Full Text Available Intussusception is the most common form of acquired gastrointestinal obstruction in children. The aim is to study the features of clinical course and treatment strategy for intussusception in children and to analyze limitations of diagnostic, clinical and special research methods. Materials and methods of the study. The analysis of treatment outcomes has been carried out in 272 children in pediatric surgery clinic from 2004 to 2015. We have developed the objective criteria for evaluation of intussusception stages that correlate with the degree of endotoxemia, changes in respiratory function and circulation, the disorders of gut motility, as well as ultrasound of the abdominal organs. Results and discussion. Patients with intussusception stage I (233 children had no signs of endotoxemia or they were non-significant. In 10 children we performed surgery, in 4 cases — laporoscopically. Of the 32 patients with stage II, in 8 cases the intussusception was straightened conservatively on the first try. We don’t make a second attempt in children with intussusception stage II. Surgical straightening was perfomed in 24 patients. Intussusception stage III in children (7 patients had signs of third degree endotoxemia. All patients of the third stage of intussusception underwent median laparotomy. In 5 cases we have detected intussusceptum necrosis, and these children were made bowel resection followed by the imposition of final ileostomy and intubation of the small intestine. In the rest (2 of patients, we managed to straighten the intussusceptum, and the gut was recognized as vital. Imposing primary anastomosis after the bowel resection in peritonitis we consider unacceptable. Conclusions. 1. Comprehensive survey of children using laboratory and instrumental methods became the basis for the allocation of 3 stages of intussusception, which correlated with the degree of endotoxemia and impaired bowel functions: stage I — compensated; stage II �

Intussusception of the small bowel through an ileostomy is very rare; when it causes necrosis of the bowel, immediate surgery is required. Computed tomography (CT) features of intussusception through an ileostomy have not been reported in the literature. Herein, we report the typical CT features of intussusception through an ileostomy, followed by a brief literature review.

Intussusception is rare in adult and usually caused by organic lesions, although there is a significant number of so-called idiopathic cases. The diagnosis of intussusception have been made by plain abdomen, barium enema and small bowel series. But recently ultrasound and computed tomography make a contribution to diagnose intussusception. Computed tomography is not the primary means for evaluating a gastrointestinal tract abnormality but also provides valuable information in evaluating disorders affecting the hollow viscera of the alimentary tract. Computed tomography image of intussusception demonstrates a whirl like pattern of bowel loops separated by fatty stripe correlating of the intestinal walls. Abdominal ultrasonogram was used as the initial diagnostic test in 2 cases out of total 4 cases, with abdominal mass of unknown cause. It revealed a typical pattern, composed of a round or oval mass with central dense echoes and peripheral poor echoes. We report 4 all cases of intussusception in adult who were performed by computed tomography and/or ultrasound. All cases were correlated with barium enema examination and/or surgical reports.

The vast majority of symptomatic intussusceptions in children arise in the ileum and are either ileocolic or ileoileocolic. The clinical diagnosis of these ''idiopathic'' intussusceptions may be difficult to make. Failure to make a prompt diagnosis and initiate appropriate treatment may lead to bowel ischemia, perforation, peritonitis, shock and even death. The clinician, therefore, may have to rely on imaging procedures to diagnose or exclude the presence of intussusception promptly and accurately. The imaging diagnosis of intussusception can be made with sonography or plain abdominal radiographs or by contrast (including air) enema examinations of the colon. This article highlights the current concepts and some controversial issues related to the imaging diagnosis of intussusception. (orig.)

Full Text Available Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma. A 33-year-old man was admitted to our hospital with three weeks history of colicky epigastric pain. Computed tomography revealed thickening of the ileal wall suggestive of intussusception. Colonoscopy revealed an ileocolic intussusception. Barium enema for reduction of ileocolic intussusception demonstrated a small bowel tumor in the ileum 15 cm proximal to the ileocecal valve. The intussusception was reduced, and the patient underwent partial resection of the ileum encompassing the small bowel tumor. Histological findings confirmed the diagnosis of lipoma of the small bowel. The patient made a satisfactory recovery and remains well.

Jejunal intussusception in a Chinese 10-year-old boy affected by the blue rubber bleb nevus syndrome is presented and discussed. The syndrome is rare, sporadically found with possible dominant inheritance, and due to a gene mutation mapped on the short arm of chromosome 9. It presents with distinctive cutaneous and gastrointestinal malformations together with possible other organ involvement. Gastrointestinal malformations tend to bleed and lead to anaemia. Infrequent complications of the gastrointestinal malformations are volvulus, intestinal infarction and intussusception. The age of the patient and the jejunal intussusception precipitated by a vascular malformation containing calcifications (which were also found in different gut segments) make this case remarkable.

2008-08-01

Full Text Available An eighty-year-old female was transferred to the hospital after experiencing abdominal pain and nausea. She had had a history of total gastrectomy for gastric cancer 14 years previously. Abdominal X-ray revealed a localized expansion of the small bowel. Computed tomography revealed a mass with a lamellar structure in a concentric circle. With a tentative diagnosis of small bowel obstruction due to intussusception, she underwent emergency operation. Laparotomy revealed a retrograde jejuno-jejunal intussusception. Bowel resection was performed due to the severe ischemic damage. All reported intussusception cases after total gastrectomy displayed retrograde characteristics and could occur both during the early and late period after surgery. It is important to consider the possibility of intussusception for patients presenting with acute abdomen who have previously undergone gastric resection.

The medical records of seven cats with intestinal intussusception that were diagnosed by abdominal ultrasonography and exploratory laparotomy were reviewed. In transverse ultrasonographic sections the intussusception appeared as a target-like mass consisting of one, two or more hyperechoic and hypoechoic concentric rings surrounding a C-shaped, circular or non-specific shaped hyperechoic centre. Part of the intestine representing the inner intussusceptum, located close to the hyperechoic centre and surrounded by concentric rings, was also detected. In longitudinal sections the intussusception appeared as multiple hyperechoic and hypoechoic parallel lines in four cases and as an ovoid mass in three cases. In one case the ovoid mass had a 'kidney' configuration. Additional ultrasonographic findings associated with intestinal intussusception included an intestinal neoplasm in one cat. The results of the present study demonstrate that the ultrasonographic findings of intestinal intussusception in cats bear some similarities to those described in dogs and humans, are relatively consistent, and facilitate a specific diagnosis.

Full Text Available Abstract Background Estimates of baseline incidence of childhood intussusception could help safety monitoring after the introduction of rotavirus vaccines. We studied the incidence of intussusception in Uzbekistan, a GAVI-fund eligible state in Central Asia. Methods We retrospectively reviewed intussusception cases in children Results Over a 5-year study period, 67 confirmed cases were identified, of which 67% were boys. The median age was 12 months, and no seasonal trend in the distribution of cases was observed. The diagnostic methods used included abdominal radiography (87% and ultrasonography (57%. Intussusception reduction by air enema was successful in 33 (49% patients and 34 (50% cases underwent surgery. A total of 4 deaths occurred, including 3 deaths in infants aged 0-6 months. The median length of hospital stay was 7.3 (range 0-37 days. The incidence of intussusception is estimated at 23 (95% CI 13.6-32.4 cases per 100,000 child-years, corresponding to approximately 237 cases annually. Conclusions This is the first study to estimate the incidence of childhood intussusception prior to the introduction of the rotavirus vaccination in Uzbekistan. A prospective surveillance system using a standardized case definition is needed in order to better examine the occurrence of intussusception in developing countries.

The incidence and location of heterotopic bone formation following total shoulder arthroplasty were evaluated in 58 Neer Mark-II total shoulder replacements. One year after surgery, 45% had developed some ectopic ossification. In six shoulders (10%) the ossifications roentgenographically bridged...... the glenohumeral and/or the glenoacromial space. There was no correlation between shoulder pain and the development of ossification. Shoulders with grade III heterotopic bone formation had a limited range of active elevation compared with shoulders without or with only a milder lesion. Men and patients...... with osteoarthritis of the shoulder joint were significantly disposed to the development of heterotopic bone. Heterotopic bone formation following total shoulder arthroplasty is frequent, but disabling heterotopic ossifications seem to be rare....

Aim: To investigate the frequency, clinical significance, and outcome of small-bowel intussusceptions in adults detected using ultrasound in an outpatient setting. Patients and methods: In two different retrospective (January 2001 to April 2003) and prospective (May 2003 to June 2005) periods, 33 small-bowel intussusceptions were found in 32 patients (13 females; mean age: 38.1 years) with known or suspected intestinal disease. Patients underwent diagnostic work-up to assess any organic disease. Patients with self-limiting intussusception were submitted to clinical and ultrasonographic follow-up. Results: Of the 32 patients with small-bowel intussusception, 25 were identified in the prospective series of 4487 examinations (0.53%) and seven in the retrospective series of 5342 examinations (0.15%; p = 0.002). Four patients had persistent and 28 self-limiting intussusceptions. Self-limiting intussusceptions were idiopathic in 11 patients (39%) or associated with organic diseases in 17 (Crohn's disease in 11 patients, celiac disease in three, ulcerative colitis in one patient, and previous surgery for cancer in two). Self-limiting intussusceptions were asymptomatic in 25% of patients. Conclusion: Small-bowel intussusceptions in adults are not rare and are frequently self-limiting, idiopathic, or related to organic diseases, mainly Crohn's disease and coeliac disease.

Intussusception is a medical emergency that occur with higher frequency in children under 2 years of age. Diagnosis can be difficult as the classical triad of abdominal pain, jelly stools and palpable abdominal mass is seen in less than 50% of the patients. However, the diagnosis of intussusception can be established with variable degree of accuracy using plain abdominal x-ray films, ultrasound, computed tomography or barium (or air/saline) enema. Some of these imaging methods are also useful during treatment of this condition. The authors present a review of the literature and a pictorial essay of the imaging findings in patients with intussusception. In addition, a discussion on the current and controversial issues related to the treatment of intussusception is presented. (author)

Intraoperative hydrostatic reduction of intussusception

Directory of Open Access Journals (Sweden)

Chatterjee Uday

2008-01-01

Full Text Available Aims: To find out an easier way of reduction of intussusception during open surgery to avoid unnecessary bowel injury. Materials and Methods: Under general anesthesia, before laparotomy, warm normal saline was infused into the rectum with a Foley catheter and an intravenous drip set maintaining the level of the bottle at 80 cm above the operating table. After opening the abdomen, pressure was applied on the colon filled with normal saline distal to the intussusceptum. The pressure was transmitted to the intussusceptum and the walls of the intussuscipient and caused reduction of intussusception without any injury to the intussuscipient and intussusceptum. This procedure was performed on those patients on whom laparotomy was performed as a primary procedure due to nonavailability of fluoroscopy or ultrasonography. Results: Between August 1998 and July 2005, we had six patients of mean (range age 11 months (7-17 months. In two cases, at laparotomy, the intussusceptions were found to have already reduced. Conclusions: Gentle finger pressure is necessary for reduction of intussusception. This subjective "gentleness" is dependant on experience of the surgeon and varies from person to person. Focal pressure on the intussuscipient and apex of the intussusceptum by the finger during reduction may be more damaging than the diffusely transmitted hydrostatic pressure even by a less-experienced surgeon. This will avoid the needless resection and anastomosis of the intestine on many occasions.

Intussusception is a common abdominal emergency in children with significant morbidity. Prompt diagnosis and management reduces associated risks and the need for surgical intervention. Despite widespread agreement on the use of contrast enema as opposed to surgery for initial management in most cases, debate persists on the appropriate contrast medium, imaging modality, pharmacological adjuvant, and protocol for delayed repeat enema, and on the best approach for surgical management for intussusception in children. To assess the safety and effectiveness of non-surgical and surgical approaches in the management of intussusception in children. We searched the following electronic databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 8) in the Cochrane Library; Ovid MEDLINE (1950 to September 2016); Ovid Embase (1974 to September 2016); Science Citation Index Expanded (via Web of Science) (1900 to September 2016); and BIOSIS Previews (1969 to September 2016).We examined the reference lists of all eligible trials to identify additional studies. To locate unpublished studies, we contacted content experts, searched the World Health Organization International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov (September 2016), and explored proceedings from meetings of the British Association of Paedatric Surgeons (BAPS), the American Soceity of Pediatric Surgery, and the World Congress of Pediatric Surgery. We included all randomised controlled trials comparing contrast media, imaging modalities, pharmacological adjuvants, protocols for delayed repeat enema, and/or surgical approaches for the management of intussusception in children. We applied no language, publication date, or publication status restrictions. Two review authors independently conducted study selection and data extraction and assessed risk of bias using a standardised form. We resolved disagreements by consensus with a third review author when necessary. We reported

To date, antegrade intussusception involving a Roux-en-Y reconstruction has been reported only once. We report a case of acute bowel obstruction due to an intussusception involving two Roux-en-Y limbs in a 40-year-old woman with a history of chronic pancreatitis due to pancreas divisum. Four years preceding this event, the patient had undergone a Whipple procedure, and three years prior to that, a Puestow operation. The patient was successfully treated with bowel resection and a side-to-side anastomosis between the most distal aspect of the bowel and the most distal Roux-en-Y reconstruction, which preserved both Roux-en-Y reconstructions.

Synostosis Between Pubic Bones due to Neurogenic, Heterotopic Ossification

Directory of Open Access Journals (Sweden)

Subramanian Vaidyanathan

2006-01-01

Full Text Available Neurogenic, heterotopic ossification is characterised by the formation of new, extraosseous (ectopic bone in soft tissue in patients with neurological disorders. A 33-year-old female, who was born with spina bifida, paraplegia, and diastasis of symphysis pubis, had indwelling urethral catheter drainage and was using oxybutynin bladder instillations. She was prescribed diuretic for swelling of feet, which aggravated bypassing of catheter. Hence, suprapubic cystostomy was performed. Despite anticholinergic therapy, there was chronic urine leak around the suprapubic catheter and per urethra. Therefore, the urethra was mobilised and closed. After closure of the urethra, there was no urine leak from the urethra, but urine leak persisted around the suprapubic catheter. Cystogram confirmed the presence of a Foley balloon inside the bladder; there was no urinary fistula. The Foley balloon ruptured frequently, leading to extrusion of the Foley catheter. X-ray of abdomen showed heterotopic bone formation bridging the gap across diastasis of symphysis pubis. CT of pelvis revealed heterotopic bone lying in close proximity to the balloon of the Foley catheter; the sharp edge of heterotopic bone probably acted like a saw and led to frequent rupture of the balloon of the Foley catheter. Unique features of this case are: (1 temporal relationship of heterotopic bone formation to suprapubic cystostomy and chronic urine leak; (2 occurrence of heterotopic ossification in pubic region; (3 complications of heterotopic bone formation viz. frequent rupture of the balloon of the Foley catheter by the irregular margin of heterotopic bone and difficulty in insertion of suprapubic catheter because the heterotopic bone encroached on the suprapubic track; (4 synostosis between pubic bones as a result of heterotopic ossification..Common aetiological factors for neurogenic, heterotopic ossification, such as forceful manipulation, trauma, or spasticity, were absent in this

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

To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

Full Text Available Adult intussusception is rare unlike childhood variety where it is the leading cause of intestinal obstruction. Preoperative diagnosis is often difficult as the symptoms are nonspecific and so high index of suspicion is needed for early diagnosis by appropriate investigations. This is a case of 65-year-old man presented with acute intestinal obstruction whose laparotomy revealed a jejunojejunal intussusception secondary to a lipomatous lesion which was successfully treated with resection and primary anastomosis. When dealing with a case of chronic intermittent intestinal obstruction, intussusception must be kept in mind as one of the differential diagnosis.

Intussusception is relatively common in children, but it is a rare cause of abdominal pain and intestinal obstruction in adults. The aetiology, clinical presentation and management of this condition differs in adults and children. Preoperative clinical diagnosis is usually difficult due to the non-specific and intermittent nature of the symptoms. Ultrasound and computed tomography can be helpful in establishing the diagnosis. We present a case of adult ileocolic intussusception with classical radiological signs and operative findings. In adults the diagnosis of intussusception should be considered in a case of intermittent abdominal pain, especially with clinical signs of intermittent bowel obstruction.

Intussusception is a common cause of intestinal obstruction in young children. The diagnosis and treatment of intussusception has evolved over the years with ultrasound being the first choice imaging technique and a major player in the non-operative reduction of intussusception owing to its advantage of reduced morbidity and non-exposure to ionizing radiation when compared to other modalities of treatment. Aim & Objectives: The aim of this study was to evaluate the efficiency of ultrasound guided hydrostatic reduction in the management of intussusception in children and assess the predictors of reducibility. A prospective study of all infants and children who presented with uncomplicated intussusception was conducted between January, 2005 and September, 2013. The diagnosis of intussusception was made clinically and this was confirmed by an abdominal ultrasonography. Ultrasound guided hydrostatic reduction of intussusception was performed on the selected patients after they were adequately resuscitated. Failed reduction was abandoned in favour of operative reduction in some patients. Data collected included the age of the patients, duration of symptoms and the outcomes of the procedure and these were analyzed. Eighty-four patients with intussusception were treated over this period, 36(42.9%) patients were found suitable for hydrostatic reduction of intussusception. Twenty-four(66.7%) patients presented within 48 hours of onset of symptoms. Twenty-one(58.3%) patients had successful hydrostatic reduction of intussusception while 15(41.7%) patients had failed reduction. The procedure was successful in majority (58%) of the patients under the age of 1 year and one of the three (33%) patients older than one year. Hydrostatic reduction of intussusception was successful in 14 out of 24 patients (58.3%) who presented within 48 hours of onset of symptoms. Hydrostatic reduction of intussusception under ultrasound guidance is an effective and useful conservative method of

2008-01-01

We describe the case of a 68-year-old otherwise healthy male who presented to our emergency room with signs and symptoms of acute appendicitis. Exploratory surgery revealed a normal appendix. Further examination revealed an enlarged lymph node-like mass of tissue near the appendix, in the ileocecal mesentery. This mass was removed and was found to be inflamed heterotopic gastric tissue. Although reports of heterotopic gastric tissue in the literature are common, we believe that this case represents the first report of inflamed heterotopic gastric tissue simulating appendicitis.

A 48-year-old man noticed nausea and took health examination. After chest X-ray and gastrointestinal barium study was underwent, he was referred to our hospital because of abnormal shadow in the chest X-ray. CT scan revealed about 4 cm tumor in the hilum of left lung and target sign in the small intestine. He was diagnosed with intussusception and emergency operation was performed. During the laparotomy, we found 2 intussusceptions in the small intestine and we performed manual reduction using Hutchinson's maneuver. We confirmed the mass in oral side of the intussusception site but we did not confirmed any tumor in anal of the intussusception. This suggests the intussusception was caused by barium. Finally 3 small intestine tumor was observed and we resected and reconstructed each of the tumor. Histopathological examination showed small intestinal metastasis from pleomorphic carcinoma of the lung.

Endoglin inhibition leads to intussusceptive angiogenesis via activation of factors related to COUP-TFII signaling pathway.

Directory of Open Access Journals (Sweden)

Ruslan Hlushchuk

Full Text Available Angiogenesis is a highly coordinated, extremely complex process orchestrated by multiple signaling molecules and blood flow conditions. While sprouting mode of angiogenesis is very well investigated, the molecular mechanisms underlying intussusception, the second mode of angiogenesis, remain largely unclear. In the current study two molecules involved in vascular growth and differentiation, namely endoglin (ENG/CD105 and chicken ovalbumin upstream promoter transcription factor II (COUP-TFII were examined to unravel their specific roles in angiogenesis. Down- respectively up-regulation of both molecules tightly correlates with intussusceptive microvascular growth. Upon ENG inhibition in chicken embryo model, formation of irregular capillary meshwork accompanied by increased expression of COUP-TFII could be observed. This dynamic expression pattern of ENG and COUP-TFII during vascular development and remodeling correlated with formation of pillars and progression of intussusceptive angiogenesis. Similar findings could be observed in mammalian model of acute rat Thy1.1 glomerulonephritis, which was induced by intravenous injection of anti-Thy1 antibody and has shown upregulation of COUP-TFII in initial phase of intussusception, while ENG expression was not disturbed compared to the controls but decreased over the time of pillar formation. In this study, we have shown that ENG inhibition and at the same time up-regulation of COUP-TFII expression promotes intussusceptive angiogenesis.

Intussusception is one of the most common causes of paediatric emergency. Fluoroscopy-guided hydrostatic reduction is a common nonoperative management strategy for the treatment of intussusception. The role of pharmacological premedication in increasing the success rate of hydrostatic reduction is still controversial. The purpose of this study was to verify the presence of a possible correlation between pharmacological premedication and the percentage of hydrostatic reduction of intussusception in paediatric patients. This study considered children with a diagnosis of idiopathic intussusception treated at our hospital between January 2007 and June 2013. One group of patients underwent hydrostatic reduction by barium enema without any preliminary therapy. A second group of patients received pharmacological premedication with both a sedative and an anti-oedematous agent before the procedure. A total of 398 patients were treated with barium enema for therapeutic purposes. In the group of patients who received no premedication (n = 254), 165 (65 %) children achieved hydrostatic reduction of the intussusception. Among the patients who received pharmacological premedication prior to barium enema (n = 144), 122 (85 %) children achieved resolution of the intussusception. Our study shows that the use of pharmacological premedication is effective for the reduction of the intussusception, as its limit patient stress, fluoroscopic time and radiation dose.

The purpose of this study was to evaluate the adult transient intestinal intussusceptions on CT before and after the administration of gastrointestinal contrast material. We evaluated two different gastrointestinal contrast materials: hyperdense and hypodense. In all cases the gastrointestinal contrast agent solved the invaginations. In the group of patients treated with hypodense contrast medium relapses occurred in the short and long term; no recurrence was observed in the other group. CT is useful in the recognition of intestinal intussusception. The gastrointestinal contrast agent could define the real transience of intussusceptions and hyperdense contrast agent could be more effective in short and long term resolution.

Full Text Available Background: Intussusception is the common acute abdomen in children with difficult clinical diagnosis. The routine ultrasound has recently been proposed as the initial diagnostic modality with high accuracy, but is not available for 24 h by gastroenterologists. We aimed to evaluate the validation of bedside ultrasound for intussusceptions performed by pediatric emergency physicians with ultrasound training during the night or holiday. Methods: A retrospective study was conducted in children with suspected intussusceptions when routine ultrasounds by gastroenterologists were not available over the period from July 2004 to July 2008. Patients were divided into two groups: those diagnosed by emergency physicians with ultrasound training and without training. The clinical characteristics and course for all patients were reviewed and compared for seeking the difference. Results: A total of 186 children were included. One hundred and thirteen (61% children were diagnosed by pediatric emergency physician with ultrasound training. The clinical symptoms were not statistically different between the two groups. The diagnostic sensitivity of the ultrasound training group was significantly higher (90% vs. 79%, p = 0.034. Children of the training group also had significantly shorter hospital stay duration at emergency departments before reduction (2.41 ± 2.01 vs. 4.58 ± 4.80 h, p = 0.002. Conclusion: Bedside ultrasound performed by pediatric emergency physicians with ultrasound training is a sensitive test for detecting intussusceptions. Knowledge and use of bedside ultrasound can aid the emergency physician in the diagnosis of pediatric intussusceptions with less delay in treatment.

To assess the success rate and efficacy of US-guided hydrostatic reduction in children with intussusception. We retrospectively evaluated the ultrasonographic findings and clinical features of 121 children (M:F=80:41, mean age= 18 months) who underwent US-guided hydrostatic reduction between November, 2002 and February, 2007 for the diagnosis and treatment of intussusception. The 121 patients underwent 147 procedures, including recurred cases. Successful reduction was achieved in 132 cases (89.8% success rate), as confirmed by post-procedure ultrasonography and clinical findings. Emergency operations were performed in the 10 (6.8%) cases of irreducible intussusceptions, 8 of ileocolic type and 2 of ileoileal type. Perforation occurred in 4 cases (2.7%), and seizure in 1 case during the procedure (0.7%). US-guided hydrostatic reduction is a safe and effective tool for the diagnosis and treatment of pediatric intussusception

Full Text Available ABSTRACT: Introduction & Objective: Heterotopic pregnancy refers to the simultaneous occurrence of pregnancy intrauterine and outside of uterine corpus. It is most often manifested in women who have undergone artificial reproductive technology (ART but rarely occurs spontaneously. Heterotopic pregnancy still remains as a diagnostic and therapeutic challenge to practitioners. In this situation physicians should have high suspicion for diagnosis and intrauterine pregnancy protection. This study reported a case of ruptured spontaneous heterotopic pregnancy. Case: A 32 year-old woman with abdominal pain, nausea, vomiting and hypovolumic shock in 1386 referred to emergency department in Sanandaj hospital. She reported one previous cesarean section. On examination, the patient's abdomen was distended. She had generalized tenderness and rebound tenderness in abdomen. The ultrasonographic examination revealed large amount of fluid in pelvic and abdominal cavity with a large hematoma in right adnex but there was intrauterine pregnancy at 7 weeks with normal fetal heart activity. She underwent laparotomy for heterotopic pregnancy and ruptured tube with tubal pregnancy removed. Intrauterine pregnancy continued without problem and led to birth of a healthy female neonate. Conclusion: Physicians should be quite cautious of heterotopic pregnancy in woman at reproductive age. Any abnormality on physical examination or ultrasonography of a patient with intrauterine pregnancy and abdominal pain should heighten the clinician's suspicion for heterotopic pregnancy

Concurrent acute appendicitis and ileocolic intussusception in a 1-year-old child

Lauren Marjon, MD

2018-06-01

Full Text Available Intussusception and acute appendicitis are part of a differential diagnosis for acute abdominal pain and vomiting in the pediatric population. We describe a unique case combining appendiceal intussusception with concurrent acute appendicitis, or “appendi-sception.” A 1-year-old boy presented with 1 day of fussiness, vomiting, and red, gelatinous stool. Initial diagnosis on ultrasound was a routine ileocolic intussusception with nonvisualization of the appendix. However, after a failed air enema decompression, the patient was taken to the operating room where the appendix was discovered to be inflamed within the intussusceptum. This case is unique as few cases of both conditions occurring simultaneously have been previously described. It is important for radiologists to be aware of this combination of diagnoses as both require urgent evaluation and prompt treatment.

The aims of this study were to describe the reports of suspected adverse events due to rotavirus vaccines, and assess the reporting sensitivity for intussusception. Descriptive study performed using the reports of suspected adverse events following rotavirus vaccination in infants aged less than 10 months, as registered in the Pharmacovigilance Centre of the Valencian Community during 2007-2011. The reporting rate for intussusception was compared to the intussusception rate in vaccinated infants obtained using the hospital discharge database (CMBD), and the regional vaccine registry. The adverse event reporting rate was 20 per 100,000 administered doses, with the majority (74%) of the reports being classified as non-serious. Fever, vomiting, and diarrhea were the adverse events reported more frequently. Two intussusception cases, which occurred within the first seven days post-vaccination, were reported as temporarily associated to vaccination. The reporting sensitivity for intussusception at the Pharmacovigilance Centre in the 1-7 day interval following rotavirus vaccination was 50%. Our results suggest that rotavirus vaccines have, in general, a good safety profile. Intussusception reporting to the Pharmacovigilance Centre shows sensitivity similar to other passive surveillance systems. The intussusception risk should be further investigated using well-designed epidemiological studies, and evaluated in comparison with the well-known benefits provided by these vaccines.

Alexander Giakoustidis

2017-01-01

Full Text Available Intestinal intussusception in adults is a rare medical condition accounting for less than 5% of all intussusceptions. Herein we present a 45-year-old patient with a history of abdominal pain and loss of weight. CT scan revealed jejunojejunal intussusceptions. The patient was subjected to exploratory operation and small intestine resection due to a mass causing intestinal intussusception. Pathology confirmed suspected diagnosis of metastatic melanoma to small intestine secondary to melanoma, 7 years after the initial manifestation. Postoperative evaluation with 18FDG-PET/CT revealed increased uptake in the thyroid gland. Subsequent total thyroidectomy revealed severe Hashimoto thyroiditis and no signs of metastasis. The patient received adjuvant immunotherapy and is healthy with no signs of recurrence 3 years after the initial diagnosis and treatment.

BARIUM REDUCTION OF INTUSSUSCEPTION IN INFANCY

Science.gov (United States)

Denenholz, Edward J.; Feher, George. S.

1955-01-01

Barium enema reduction was used as the initial routine treatment in 29 infants with intussusception. In 22 of them the intussusception was reduced by this means. In three of eight patients operated upon the intussusception was found to be reduced. Four of the remaining five patients had clinical or x-ray evidence of complications before reduction by barium enema was attempted. Twenty-one of the patients, all of whom were observed in private practice, were treated without admission to the hospital. After reduction, these patients were observed closely by the clinician. None of these patients showed clinical or x-ray signs of complications before reduction. Certain clinical and roentgen criteria must be satisfied before it can be concluded that reduction by barium enema is complete. If there are clinical signs of complications with x-ray evidence of small bowel obstruction, only a very cautious attempt at hydrostatic reduction should be made. As the time factor is generally a reliable clinical guide to reducibility, the late cases should be viewed with greater caution. Long duration of symptoms, however, is not per se a contraindication to an attempt at hydrostatic reduction. PMID:13230908

Kim, Ji Hye

2004-01-01

To describe the sonographic (US) and clinical features of spontaneously reduced small bowel intussusception, and to discuss the management options for small bowel intussusception based on US findings with clinical correlation. During a five years of period, 34 small bowel intussusceptions were diagnosed on US in 32 infants and children. The clinical presentations and imaging findings of the patients were reviewed. The clinical presentations included abdominal pain or irritability (n = 25), vomiting (n 5), diarrhea (n = 3), bloody stool (n = 1), and abdominal distension (n = 1), in combination or alone. US showed multi-layered round masses of small (mean, 1.5 ± 0.3 cm) diameters and with thin (mean, 3.5 ± 1 mm) outer rims along the course of the small bowel. The mean length was 1.8 ± 0.5 cm and peristalsis was seen on the video records. There were no visible lead points. The vascular flow signal appeared on color Doppler images in all 21 patients examined. Spontaneous reduction was confirmed by combinations of US (n = 28), small bowel series (n = 6), CT scan (n = 3), and surgical exploration (n 2). All patients discharged with improved condition. Typical US findings of the transient small bowel intussusception included 1) small size without wall swelling, 2) short segment, 3) preserved wall motion, and 4) absence of the lead point. Conservative management with US monitoring rather than an immediate operation is recommended for those patient with typical transient small bowel intussusceptions. Atypical US findings or clinical deterioration of the patient with persistent intussusception warrant surgical exploration

Full Text Available Introduction. Intussusception is a common abdominal emergency in early childhood. It is idiopathic in more than 90% of cases with incidence of 1.5-4 per 1,000 live births. The treatment of choice is nonoperative hydrostatic or air enema reduction. Objective. The aim of the study was to evaluate the influence of clinical presentation and symptom duration in non-operative treatment, considering the indications for delayed enema reduction and its efficacy. Methods. From the total number of 107 patients with intusussception, aged from 2 months to 14 years (median 9 months, 102 (95% patients with ileo-colic intussusceptions were treated initially by ultrasound guided saline enema. Records were reviewed for patients with failed initial treatment and delayed repeated enemas or operative procedure. The predictor variable included duration of presenting symptoms. Results. Successful treatment by hydrostatic saline enemas had 58/102 (57% patients. Success in reduction was greater if symptom duration was 24 hours, (4/45 cases; 9%. Despite failed initial attempts, enema reduction was reattempted in 12 patients, with success in 7/12 (60% patients. Children with symptom duration >24 hours had a greater risk of requiring surgery (41/45 cases; 91%, p<0.001, including 5 (5% patients with ileo-ileal intussusceptions. Conclusion. The accuracy of ultrasound guided saline enema in intussusception reduction is high. Delay in presentation decreases success of non-operative treatment. Delayed enema reduction is important therapeutic option for intussusceptions. Surgical treatment is indicated in cases of complications.

Neurogenic heterotopic ossification: epidemiology and morphology on conventional radiographs in an early neurological rehabilitation population

To retrospectively evaluate neurogenic heterotopic ossification in an early neurological rehabilitation population (phases B and C) with respect to epidemiology and morphology on conventional radiographs. Over a 4-year period, 1,463 patients treated at a clinic for early neurological rehabilitation were evaluated for clinical symptoms of neurogenic heterotopic ossification. In case of clinical suspicion, plain radiographs of the expected sites were obtained. If heterotopic ossification was detected, the initial and subsequent radiographs were retrospectively analyzed for sites, size, and morphology. Immature lesions were categorized as small (<10 mm) or large (10-100 mm). The prevalence rate of neurogenic heterotopic ossification was 2.05%. The condition was most common in young male adults. The hip was the most common site accounting for more than half of the cases. Two or more ossifications were seen in 56.7% of the affected patients with approximately two-thirds showing bilateral symmetric involvement of corresponding joint regions. The size of ossifications strongly varied interindividually. Small immature lesions demonstrated less progression in size than large lesions during maturation (P < 0.05). Standard radiographs, as a fast and inexpensive technique, allow the expected size progression of heterotopic ossifications during maturation to be estimated, which is relevant in terms of therapeutic decisions, patient mobilization, and neurological rehabilitation.

The author report a case of jejunojejunal intussusception caused by an adenomatous polyp in an adult. The majority of intussusception's cases occur in children with less than 2 years of age, with only 5% to 15% of cases occurring in adults. In contrast to pediatrics group intussusception, which is idiopathic in 90% of cases, adult intussusception has a demonstrable cause in more than 90% of cases. The pre-operative diagnosis is made by the association between the clinical presentation and plain abdominal radiographs, barium study of small intestine, ultrasound and computed tomography, described and discussed in this paper.

Full Text Available Background: Intussusception is one of the most common causes of intestinal obstruction in children. While the outcome has improved in the developed nations, the same cannot be said of the developing countries, more especially in the sub-Saharan region. This study aims to review our current experience in the management of childhood intussusception and factors affecting surgical outcome at the Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife. Patients and Methods: This was a retrospective study of 78 patients treated for intussusception at paediatric surgical unit of Obafemi Awolowo University Teaching Hospitals Complex Ile-Ife between January 1993 and December 2011. The case notes of the patients were retrieved and the following information was recorded: Demographic characteristics, month of occurrence, clinical presentation, investigations, and management as well as the post-operative outcome. The patients were divided into two groups in terms of outcome. Results: There were 58 males and 20 females (M:F = 2.9-1. The age of most of the patients was between 3 months and 9 months with peak incidence at 6 months. Most patients 46 (58.9% were seen during the dry season of December to April. Only six patients (7.7% presented within 24 hours of onset of illness. More than half of the patients presented after 24 hours. Passage of red currant stool, vomiting, abdominal pain, fever, and abdominal distension, passage of watery stool, anal protrusion and palpable abdominal mass in various combinations were the clinical features. All the patients had surgical operations. The most common type of intussusception was ileo-colic type in 64 patients (82.1%. Intestinal resection rate was 41%. The overall mortality rate was 15.4%. Conclusion: There was a delay in presentation of children with intussusception with high post-operative mortality.

Although heterotopic gestation is common in assisted reproductive techniques, it is very rare in natural conception and clomiphene induced pregnancy. Diagnosis and appropriate intervention of heterotopic pregnancy requires a high index of suspicious. In this paper a case of heterotopic pregnancy in a 30-year old woman with hemoperitoneum from ruptured tubal pregnancy with live intrauterine gestation at 9 weeks of gestation is reported. This case suggests that a heterotopic pregnancy must always be considered particularly after the induction of ovulation by clomiphene citrate or assisted reproductive technology. Every clinician treating women of reproductive age should keep this diagnosis in mind. It also demonstrates that early diagnosis is essential in order to salvage the intrauterine pregnancy and avoid maternal morbidity and mortality.

Appendiceal intussusception is a rare condition that can occur at any age. Only a few cases have been reported, and most are found during surgery. The therapeutic approach is usually surgical, ranging from an appendectomy to a hemicolectomy, primarily for biopsy and to rule out possible malignancy. Three cases of children under 14 years who underwent surgery for acute abdominal pain located in the right iliac fossa are presented; one with preoperative diagnosis by ultrasound, and the other two with positive intraoperative findings of intussusception of the cecal appendix, with acute appendicitis being histologically confirmed.

Intussusception is defined as telescoping of one segment of the gastrointestinal tract into an adjacent one. Unlike that in children, adult intussusception is a relatively rare condition. More than 90% of patients with adult intussusception have been reported to have an organic cause, with benign or malignant tumors for accounting for approximately 65% of the cases. In general, the diagnosis is easily made by means of computed tomography (CT) or magnetic resonance (MR) imaging. The imaging appearance of a bowel-within-bowel configuration with or without contained fat and mesenteric vessels, is pathognomonic. As the intussusceptum enters into the intussuscipiens, the mesentery is carried forward and trapped between the overlapping layers of bowel. The twisting or severe constriction of the mesenteric vessels may result in vascular compromise with subsequent edematous thickening of the involved bowel. In these circumstances, ischemic necrosis may develop if timely intervention is not undertaken. Therefore, determination of the presence or absence of intestinal necrosis in intussusception is important in patient management. On CT, the presence of well-known diagnostic CT criteria for strangulated obstruction (especially severe engorgement or twisting of the mesenteric vessels) as well as evidence of loss of the layered pattern, accumulation of extraluminal fluid collection, and bowel perforation, may suggest the diagnosis of intestinal necrosis. CT and MR imaging are limited in determining the primary disease causing intussusception. However, CT and MR provide excellent pre-operative evaluation, including the possible extension and/or dissemination of a malignant tumor. CT and MR imaging may also be useful in suggesting the presence of vascular compromise

Purpose: Osteogenesis imperfecta is a rare hereditary disease of connective tissue with a genetic defect in collagen synthesis. In osteogenesis imperfecta hyperplastic heterotopic ossification can be induced by hyperplastic callus formation caused by trauma or operation. Heterotopic ossifications can be found in numerous benign diseases. The successful use of low dose radiotherapy in the treatment of heterotopic ossifications in well-known from the literature. Patients and Methods: We treated two children (a 13-year old girl and a ten-year old boy) with heterotopic ossifications of the lower extremities in osteogenesis imperfecta type IV (Lobstein) with a low dose irradiation (10x1 Gy, respectively 6x1 Gy) under megavoltage conditions. Results: After radiotherapy the children were painfree and the hyperplastic callus was considerably reduced. The previously immobilized patients could partly be mobilized. Thereby it could be contributed to the rehabilitation of the patients. New hyperplastic callus formation was not observed in the irradiated areas so far. Conclusion: Analogous to the successful radiation of heterotopic ossifications in other benign diseases radiation therapy seems to be a successful treatment of hyperplastic callus formation in osteogenesis imperfecta. Despite the late risks of radiotherapy radiation treatment of benign diseases in children might be indicated. (orig.)

Purpose/Objective: To determine the effect of post-operative radiation on the incidence of heterotopic ossification following traumatic acetabular fracture. Materials and Methods: A retrospective analysis was performed of the medical records and radiographs of all patients who received prophylactic radiotherapy to prevent heterotopic ossification. These results were compared to a similar group of patients receiving no prophylactic radiotherapy following traumatic acetabular fracture. Between 1987 and 1994, sixty-six patients received prophylactic radiotherapy to prevent heterotopic ossification. Results: Thirty-six patients (55%) received radiotherapy following operative repair of a traumatic acetabular fracture (median follow-up: 210 days). Three dose schedules were utilized: (28(36)) (77.8%) received 700 cGy/1 fx, (2(36)) (5.5%) 800 cGy/1 fx, and (6(36)) (16.7%) 1000 cGy/5 fxs. These patients were retrospectively compared with thirty-four patients who received similar operative management of traumatic acetabular fractures without post-operative radiotherapy (median follow-up: 378 days). Of the patients with heterotopic ossification, 96% developed it within 180 days. Complications and delayed wound healing rates were not significantly different in patients treated with or without post-operative radiotherapy, 6.4% and 6.3% respectively (p=0.49). The incidence of heterotopic ossification at last follow-up in patients treated with and without post-operative radiotherapy was (5(36)) (13.9%) and (19(34)) (55.9%), respectively (p=0.000332). For all patients, type of surgical approach was associated with development of heterotopic ossification: posterior, (7(38)) (18.4%), ilio-inguinal (1(3)) (33.3%), tri-radiate (13(19)) (68.4%), p=.000511. In patients receiving post-operative radiotherapy, variables associated with heterotopic ossification included dose (p=.00962), injury-to-radiation interval (p=.0038), and surgery-to-radiation interval (p=.0238).

Post licensure studies have identified an increased risk of intussusception following vaccination with currently licensed rotavirus vaccines, raising safety concerns generic to all rotavirus vaccines. We describe the surveillance for intussusception in a phase III clinical trial with an oral monovalent rotavirus vaccine developed from the neonatal 116E strain. Using broad screening criteria and active surveillance, the incidence of intussusception between 6 weeks and 2 years of age was measured in 4532 children who received three doses of vaccine and 2267 children who received a placebo in the clinical trial. Possible intussusceptions were evaluated with a screening ultrasonogram. An independent intussusception case adjudication committee reviewed all intussusceptions and graded them on Brighton Collaboration criteria for diagnostic certainty. We identified twenty-three intussusceptions on ultrasound from 1361 evaluated sentinel events. Eleven were of level 1 diagnostic certainty as determined by the independent intussusception case adjudication committee. None required surgical intervention, and the earliest identified intussusception was at 36 days following the third dose in a placebo recipient. Among vaccine recipients the first event of intussusception occurred 112 days after the third dose. The incidence of ultrasound-diagnosed intussusception was 200/100,000 child-years (95% CI, 120, 320) among those receiving the vaccine and 141/100,000 child-years (95% CI, 50, 310) among those receiving the placebo. The incidence rate of confirmed intussusception among vaccine recipients was 94/100,000 child-years (95% CI, 41, 185) and 71/100,000 child-years (95% CI, 15, 206) among those receiving the placebo. In this licensure study, 23 cases of intussusception were identified through an active surveillance system, but there was no temporal association with rotavirus vaccination. The use of active surveillance with broad criteria intended for ensuring safety of children

The purposes of this study were to evaluate the plain radiologic findings of the childhood intussusception and to evaluate the role of plain abdominal films in predicting the success of air or barium reduction. We retrospectively reviewed 140 cases with the diagnosis of intussusception in childhood. The radiological signs that included soft tissue mass, dilatation of small bowel suggesting obstruction, crescent sign, and target sign were evaluated in terms of frequency. The relationship between radiological findings and outcome of reduction was analyzed. The site of soft tissue mass or crescent sign seen on plain radiographs was correlated with the position of the apex of the intussusceptum seen at the beginning of barium edema. The degree of dilated small bowel was evaluated by calculating the proportion of air-filled small bowel occupying peritoneal cavity and measuring the maximal diameter of dilated bowel lumen. The radiological finding for small bowel obstruction is determined by observation of the degree of small bowel dilatation and/or air-fluid levels. Ninety-two cases out of 140 showed one or more radiographic signs. Two most common signs were soft tissue mass and small bowel obstruction. The success rate of air or barium reduction was significantly lower in patients with most severe degree of dilatation of small bowel and/or more than 7 air-fluid levels on erect view. The suspected location of intussusception on plain radiographs correlated well with the true location of intussusception seen in the first few seconds of barium reduction. Plain abdominal radiography is useful in the diagnosis of intussusception and provides helpful information for the reduction procedure as well as for the exclusion of the contraindications such as bowel perforation

Pneumatic reduction of intussusception under fluoroscopic guidance is a routine procedure. The unsedated child may resist the procedure, which may lengthen its duration and increase the radiation dose. We use deep sedation during the procedure to overcome these difficulties. The purpose of this study was to summarize our experience with deep sedation during fluoroscopic reduction of intussusception and assess the added value and complication rate of deep sedation. All children with intussusception who underwent pneumatic reduction in our hospital between January 2004 and June 2011 were included in this retrospective study. Anesthetists sedated the children using propofol. The fluoroscopic studies, ultrasound (US) studies and the childrens' charts were reviewed. One hundred thirty-one attempted reductions were performed in 119 children, of which 121 (92%) were successful and 10 (8%) failed. Two perforations (1.5%) occurred during attempted reduction. Average fluoroscopic time was 1.5 minutes. No complication to sedation was recorded. Deep sedation with propofol did not add any complication to the pneumatic reduction. The fluoroscopic time was short. The success rate of reduction was high,raising the possibility that sedation is beneficial, possibly by smooth muscle relaxation.

Spontaneous Heterotopic Pregnancy: Dual Case Report and Review of Literature

Directory of Open Access Journals (Sweden)

Annika Chadee

2016-01-01

Full Text Available Introduction. Heterotopic pregnancy is a rare complication usually seen in populations at risk for ectopic pregnancy or those undergoing fertility treatments. It is a potentially dangerous condition occurring in only 1 in 30,000 spontaneous pregnancies. With the advent of Assisted Reproduction Techniques (ART and ovulation induction, the overall incidence of heterotopic pregnancy has risen to approximately 1 in 3,900 pregnancies. Other risk factors include a history of pelvic inflammatory disease (PID, tubal damage, pelvic surgery, uterine Mullerian abnormalities, and prior tubal surgery. Heterotopic pregnancy is a potentially fatal condition, rarely occurring in natural conception cycles. Most commonly, heterotopic pregnancy is diagnosed at the time of rupture when surgical management is required. Case. This paper represents two cases of heterotopic pregnancies as well as a literature review. Conclusion. Heterotopic pregnancy should be suspected in patients with an adnexal mass, even in the absence of risk factors. Clinicians must be alert to the fact that confirming an intrauterine pregnancy clinically or by ultrasound does not exclude the coexistence of an ectopic pregnancy. A high index of suspicion in women is needed for early and timely diagnosis, and management with laparotomy or laparoscopy can result in a favorable and successful obstetrical outcome.

Mantle cell lymphoma of the gastrointestinal tract presenting with multiple intussusceptions – case report and review of literature

Directory of Open Access Journals (Sweden)

Abo Stephen M

2009-07-01

Full Text Available Abstract Background Mantle cell lymphoma (MCL is an aggressive type of B-cell non-Hodgkin's lymphoma that originates from small to medium sized lymphocytes located in the mantle zone of the lymph node. Extra nodal involvement is present in the majority of cases, with a peculiar tendency to invade the gastro-intestinal tract in the form of multiple lymphomatous polyposis. MCL can be accurately diagnosed with the use of the highly specific marker Cyclin D1. Few cases of mantle cell lymphoma presenting with intussuception have been reported. Here we present a rare case of multiple intussusceptions caused by mantle cell lymphoma and review the literature of this disease. Case presentation A 68-year-old male presented with pain, tenderness in the right lower abdomen, associated with nausea and non-bilious vomiting. CT scan of abdomen revealed ileo-colic intussusception. Laparoscopy confirmed multiple intussusceptions involving ileo-colic and ileo-ileal segments of gastrointestinal tract. A laparoscopically assisted right hemicolectomy and extended ileal resection was performed. Postoperative recovery was uneventful. The histology and immuno-histochemistry of the excised small and large bowel revealed mantle cell lymphoma with multiple lymphomatous polyposis and positivity to Cyclin D1 marker. The patient was successfully treated with Rituximab-CHOP chemotherapy and remains in complete remission at one-year follow-up. Conclusion This is a rare case of intestinal lymphomatous polyposis due to mantle cell lymphoma presenting with multiple small bowel intussusceptions. Our case highlights laparoscopic-assisted bowel resection as a potential and feasible option in the multi-disciplinary treatment of mantle cell lymphoma.

Intestinal occlusion due to intussusception produced by intestinal tumors is a very rare condition. Gastrointestinal stromal tumors are also rare digestive neopasias, with an impredictable malignant behavior, which are usually growing outside the intestinal wall, being rarely the initiators of an intestinal intussusception. We present the case of a 59 years old female, admitted in our hospital to elucidate the etiology of her iron deficient anaemia, which developed an intestinal occlusion at the intestinal preparation for colonoscopy. The abdominal CT scan performed in emergency conditions highlighted occlusive intestinal tumor complicated with intestinal intussusception. We performed an emergency laparotomy that revealed intestinal occlusion due to ileo-ileal intussusception produced by an ileal tumor. The surgical intervention consisted in segmental ileal enterectomy including the tumor with latero-lateral entero-enteral anastomosis. The patient recovered without complications. The histopathological and immunohisto-chemical examinations established the diagnose of gastro-intestinal stromal tumor with high risk malignant behavior, therefore the patient was guided in the oncological department for specific treatment and oncological surveillance.

The study was undertaken to assess the efficacy of ultrasound-guided saline enema in reducing intussusception and to determine the role of age and duration of symptoms on this event. The case records of patients who were treated for intussusception at our institutions over the past 10 years were retrospectively analyzed. A total of 419 patients were treated for intussusception and 375 of them were included into the study. Patients were excluded if they had symptoms and signs of acute abdominal disease and required surgery as an initial treatment. Hydrostatic reduction was successful in 313 of the 375 patients (83.46%). The procedure-related complication rate was nil. There were 29 episodes of recurrences in 23 patients, and recurrence rates did not differ between patients who responded to hydrostatic reduction and those who required surgery. Younger age [median (range); 11 months (3-108 months) vs. 20 months (1-180 months); phydrostatic reduction. Ultrasound-guided hydrostatic reduction is an easy, safe and effective method for the treatment of intussusception in the absence of acute abdominal findings. Copyright © 2015 Elsevier Inc.

Ileocecal Burkitt's Lymphoma Presenting as Ileocolic Intussusception With Appendiceal Invagination and Acute Appendicitis

Directory of Open Access Journals (Sweden)

Sheng-Mine Wang

2010-06-01

Full Text Available Intussusception is a common cause of abdominal pain in children. Although most cases are idiopathic, about 10% of cases have a pathologic lead point. Burkitt's lymphoma is not a common etiology. Burkitt's lymphoma might present primarily as intussusception in children but has rarely been associated with appendicitis. We report a case in which a 10-year-old obese boy who initially presented with acute appendicitis due to ileocolic intussusception with appendiceal invagination. He underwent one-trocar laparoscopy and antibiotic treatment. The symptoms recurred 10 days after discharge. Colonoscopy disclosed ileocecal Burkitt's lymphoma as the pathological lead point. This case emphasizes the importance of the age of the patient and the anatomic location of the intussusception related to possible etiology, and hence the most appropriate surgical procedure.

Intussusception is defined as the telescoping of one segment of the gastrointestinal tract into an adjacent one. It is relatively common in children and is the second most common cause of an acute abdomen in this age group. It is much less common in adults and accounts for less than 5% of cases of mechanical small bowel obstruction. Whereas the diagnosis is usually already suspected in children before imaging, it is often made unexpectedly in adults. In addition, although in children there is usually no specific underlying cause, an underlying lead point is often present in adults. Plain film radiography, barium studies and ultrasound imaging play major roles in both the diagnosis and management of this condition, and it is increasingly common for the diagnosis to be made by CT and MRI, particularly in adults. This pictorial essay reviews the imaging features that may be found in patients with bowel intussusception. As well as describing the imaging features of the more commonly used tests, we also stress the role of emerging technologies such as MRI using ultrafast half-fourier sequences with single shot turbo spin echo

Gastroduodenal intussusception is a rare condition caused by the prolapse of a gastric tumor with subsequent invagination of a portion of the gastric wall into the duodenum. Various gastric lesions including adenoma, lipoma, leiomyoma, hamartoma, adenocarcinoma, gastrointestinal stromal tumor (GIST), and as in our case a Peutz- Jeghers polyp, can serve as a lead point of intussusception. Only three cases of gastroduodenal intussusception secondary to a Peutz-Jeghers polyp have been reported. We experienced a case of gastroduodenal intussusception in a 36-month-old boy who presented with intermittent nonbilious vomiting, abdominal pain, and anemia. An abdominal ultrasound and contrast enhanced CT scan showed gastrointestinal intussusception and a mass-like lesion in the second portion of duodenum. A laparotomy revealed a 7x8 cm sized mass at the gastric body, which was pathologically confirmed as a Peutz-Jeghers polyp

Limited utility of plain abdominal radiographs in evaluating intussusceptions secondary to long indwelling feeding tubes

Full Text Available Adult intussusception (AI is relatively rare and can be a difficult clinical diagnosis, often requiring cross-sectional imaging for confirmation. Unfortunately, intussusceptions in the setting of indwelling long enteral feeding tubes have been predominantly characterized in the pediatric population with minimal investigation in adults. We report three cases of AI in patients with long feeding catheters serving as anatomic lead points leading to intussusception diagnosed on cross-sectional imaging. We highlight the limited utility of the supine plain films for detection of AI, and it behooves the radiologist to hold a high index of suspicion if the patient has a long enteral catheter. Since the majority of these patients tend to be fairly ill and unable to stand for upright abdominal radiographs, in the setting of percutaneous feeding tubes, decubitus abdominal radiographs should always be obtained. These cases also highlight the importance of having a high clinical suspicion of intussusceptions in a patient presenting with abdominal pain in the setting of an enteral feeding tube. In post-operative patients, other factors can predispose the patient to intussusception, including adhesions. Another interesting feature in tube related AI is the reverse intussusception that may be seen with indwelling enteral tubes. Reverse intussusception is where the distal bowel telescopes into the proximal segment over the tube.

Full Text Available Heterotopic pancreas is a rare condition and its diagnosis is often difficult. Traditionally the condition is treated by open surgery. We report two young women with symptomatic heterotopic pancreas located in the prepyloric region. In the first patient, upper gastrointestinal endoscopy identified a round sessile lesion with a central umbilication of the mucosa without bleeding and in the second endoscopy showed a lesion with intraluminal protrusion. In both cases, a diagnostic laparoscopy identified masses amenable to laparoscopic excision. Intraoperative histology confirmed ectopic pancreatic tissue in both. In the treatment of heterotopic pancreas, laparoscopic excision provides a feasible, safe and effective treatment option.

Full Text Available Introduction. Intussusception is a rare clinical entity in adults (<1% of intestinal obstructions. Colonic intussusception is even rarer, particularly when caused by lipomas. Case Presentation. A 47-year-old woman presented to our emergency department complaining of abdominal pain with vomiting and diarrhoea. X-ray and CT showed bowel obstruction due to ileocolonic and colocolonic intussusception; a giant colonic lipoma (9 × 4 × 4 cm was recognizable immediately distally to the splenic flexure of the colon. The patient underwent emergency laparotomy and right hemicolectomy. Assessment of the resected specimen confirmed the diagnosis of giant colonic polypoid lesion near to the ileocecal valve, causing a 12 cm long intussusception with moderate ischemic damage. Conclusion. Colonic obstruction due to intussusception caused by lipomas is a very rare condition that needs urgent treatment. CT is the radiologic modality of choice for diagnosis (sensitivity 80%, specificity near 100%; since the majority of colonic intussusceptions are caused by primary adenocarcinoma, if the etiology is uncertain, the lesion must be interpreted as malignant and extensive resection is recommended. At present, surgery is the treatment of choice and determines an excellent outcome.

Methods: Data from intussusception patients who were treated with nonsurgical reduction in Chiang Mai University Hospital and Siriraj Hospital between January 2006 and December 2012 were collected. Patients aged 0–15 years and without contraindications (peritonitis, abdominal X-ray signs of perforation, and/or hemodynamic instability were included for nonsurgical reduction. The success and failure groups were divided according to the results of the reduction. Prognostic indicators for failed reduction were identified by using generalized linear model for exponential risk regression. The risk ratio (RR was used to report each factor. Results: One hundred and ninety cases of intussusception were enrolled. Twenty cases were excluded due to contraindications. A total of 170 cases of intussusception were included for the final analysis.

The authors report a case of a 28-year-old woman with ileocecocolic intussusception due to Peutz-Jeghers syndrome, an autosomal dominant disorder characterized by hamartomatous polyposis of the gastrointestinal tract and mucocutaneous pigmentation. This condition frequently presents complications such as intestinal obstruction due to invagination or hemorrhage. In this patient, the diagnosis of intussusception was made preoperatively. The excised material revealed three large polyps which were considered to be the cause of the intussusception. (author)

Full Text Available Aim: To evaluate an alternative way of reducing intussusceptions under laparoscopic guidance. Materials and Methods: This is a retrospective observational study of children who underwent laparoscopy-assisted hydrostatic in situ reduction of intussusceptions (LAHIRI. Under general anesthesia with laparoscopic vision, warm saline was infused into the rectum with a 16-18 F Foley catheter and a drip set till the intussusception was reduced. Results: Eleven patients [age 7.8 (±2.8 months] were operated over a period of 1 year. Ten (90.9% patients had ileocolic intussusception, which got completely reduced, but one (9% had ileo-ileocolic intusussception, in whom manual reduction by extending the subumbilical incision was required to reduce the ileoileal part. The mean duration of surgery was 38.5 (±6.6 min. No patient had bowel ischemia and there were no intra- or postoperative complications. Conclusions: LAHIRI appears to be an effective and safe technique in children. Specific advantages are that it is performed in a controlled environment in the operating room, avoids patient apprehension and discomfort, avoids bowel handling, provides a safe opportunity to create higher intraluminal pressure, ensures visual assessment of bowel vascularity and completeness of reduction.

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 encountered multiple cases in which the US appearance of ruptured appendicitis mimicked intussusception, resulting in diagnostic and therapeutic delay and multiple additional imaging studies. To explore the clinical and imaging discriminatory features between the conditions. Initial US images in six children (age 16 months to 8 years; 4 boys, 2 girls) were reviewed independently and by consensus by three pediatric radiologists. These findings were compared and correlated with the original reports and subsequent US, fluoroscopic, and CT images and reports. All initial US studies demonstrated a multiple-ring-like appearance (target sign, most apparent on transverse views) with diagnostic consensus supportive of intussusception. In three cases, US findings were somewhat discrepant with clinical concerns. Subsequently, four of the six children had contrast enemas; two were thought to have partial or complete intussusception reduction. Three had a repeat US examination, with recognition of the correct diagnosis. None of the US examinations demonstrated definite intralesional lymph nodes or mesenteric fat, but central echogenicity caused by debris/appendicolith was misinterpreted as fat. All showed perilesional hyperechogenicity that, in retrospect, represented inflamed fat ''walling off'' of the perforated appendix. There were four CTs, all of which demonstrated a double-ring appearance that correlated with the US target appearance, with inner and outer rings representing the dilated appendix and walled-off appendiceal rupture, respectively. All six children had surgical confirmation of perforated appendicitis. Contained perforated appendicitis can produce US findings closely mimicking intussusception. Clinical correlation and careful multiplanar evaluation should allow for sonographic suspicion of perforated appendicitis, which can be confirmed on CT if necessary. (orig.)

Duodenal obstruction caused by ileocolic intussusception in the absence of intestinal malrotation is extremely rare. We present and discuss the imaging findings in an infant with an intussusception secondary to a duplication cyst in whom sonography also showed inversion of the orientation of the mesenteric vessels and a distended stomach. A contrast medium study revealed a proximal duodenal obstruction with a beak appearance suggestive of midgut volvulus. At surgery, an ileocolic intussusception causing duodenal obstruction without concomitant malrotation or volvulus was found. The combination of duodenal obstruction and abnormal relationship of the mesenteric vessels as a result of ileocolic intussusception has not previously been reported in the literature. (orig.)

Objective: To have a further study of the value of MSCT in diagnosing acute small bowel retrograde intussusception in adults by means of 64-slice-spinal CT. Methods: A 46-year-old female patient with the history of abdominal operation was found having acute mechanical small bowel obstruction through plain X-ray radiograph. 64-slice MSCT was performed afterwards (plain scan + 3 stage contrast scans). Hence, evidence is provided for operation. Results: Using the technique of MSCT for the patient can promptly approach the diagnosis of jejuno-jejunal intussusception with severe bowel obstruction; no small bowel tumor or other organic lesion found in this case. With the patient who has the history of abdominal operations, MSCT can predict the reason of adhesion causing bowel intussusception, and provide the evidence for operation; whereas MSCT with contrast media offers a further investigation of the blood supply to the bowels through SMA, and observation of blood circulation through the intussuscepting site, which represents venous congestion of intussusception. This case is a retrograde small bowel intussusception and confirmed with operation evidence. A greater amount of gas and fluid is accumulated between the dilated space of middle-distal portion of intussusceptum and intussuscipiens. Nevertheless, less gas at the proximal portion and that can be an important sign for retrograde intussusception. Conclusion: MSCT is a good choice of examination for diagnosis of adult's intussusception. As the literature mentioned the advantages of MSCT for observing the circulation of intussusceptum and whether the diagnosis is antegrade or retrograde intussusception is also essential. (authors)

Single-dose radiation therapy was prospectively evaluated for its efficacy in prevention of heterotopic ossification in patients at high risk after total hip arthroplasty. Thirty-one patients (34 hips) were treated between 1981 and 1988. Risk factors for inclusion in the protocol included prior evidence of heterotopic ossification, ankylosing spondylitis, and diffuse idiopathic skeletal hyperostosis. Patients with hypertrophic osteoarthritis or traumatic arthritis with osteophytes were not included. Operations on 34 hips included 19 primary total and 11 revision total hip arthroplasties and 4 excisions of heterotopic ossification. All patients received radiotherapy to the hip after operation with a single dose of 700 centigray. Radiotherapy is recommended on the first postoperative day. After this single-dose radiation treatment, no patient had clinically significant heterotopic ossification. Recurrent disease developed in two hips (6%), as seen on radiography (grades 2 and 3). This series documents a 100% clinical success rate and a 94% radiographic success rate in preventing heterotopic ossification in patients at high risk after total hip arthroplasty. Single-dose radiotherapy is as effective as other radiation protocols in preventing heterotopic ossification after total hip arthroplasty. It is less expensive and easier to administer than multidose radiotherapy

Whole body /sup 99m/T-pyrophosphate bone scans were obtained and correlated with skeletal radiographs for detection of heterotopic ossification in 135 spinal injury patients. There were 40 patients with recent injury (less than 6 months) and 95 with injury of over 6 months duration. Heterotopic new bone was detected on the bone scan in 33.7% of 95 patients with spinal cord injuries of more than 6 months duration and 30% of 40 patients with injuries of less than 6 months. The radionuclide scan was found to be useful in detection of heterotopic ossification at its early stage and in its differentiation from other complications in spinal cord injury patients

Full Text Available Abstract Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. We report a case of a woman who presented an ileocecal intussusception due to a cecal endometriosis. The patient gave two months history of chronic periombilical pain requiring regular hospital admission and analgesia. The symptoms were not related to menses. A laparotomy was performed and revealed an ileocolic intussusception. The abdominal exploration did not find any endometriosis lesion. Ileocaecal resection was performed. Microscopic examination showed a cystic component, lined by a regular cylindric epithelium. Foci of endometrial tissu were oberved in the cecal subserosa and muscularis mucosal, with irregular endometrial glands lined by cylindric epithelium without atypia immunostained with CK7, and characteristic endometrial stroma immunostained with CD10. Cecal endometriosis and ileocolic intussusception due to a cecal endometriosis is extremely rare. Diagnose of etiology remains challenging due to the absence of clinical and radiological specific characteristics.

Chen Chuang-Wei

2012-12-01

Full Text Available Abstract Intussusception is uncommon in adults. To our knowledge, synchronous colocolic intussusceptions have never been reported in the literature. Here we described the case of a 59-year-old female of synchronous colocolic intussusceptions presenting as acute abdomen that was diagnosed by CT preoperatively. Laparotomy with radical right hemicolectomy and sigmoidectomy was undertaken without reduction of the invagination due to a significant risk of associated malignancy. The final diagnosis was synchronous adenocarcinoma of proximal transverse colon and sigmoid colon without lymph nodes or distant metastasis. The patient had an uneventful recovery. The case also emphasizes the importance of thorough exploration during surgery for bowel invagination since synchronous events may occur.

Perivascular epithelioid-cell tumor (PEComa) is a group of rare mesenchymal neoplasms that express myomelanocytic-cell markers and exhibit a wide variety of histopathological features. Although heterotopic pancreas has been reported to occur in the gastrointestinal tract, intrahepatic heterotopic pancreas has been reported only rarely. We present a case of intrahepatic PEComa that showed a strong regional correlation with the presence of heterotopic pancreas. An intrahepatic tumor and biliary dilatation was incidentally discovered during a diagnostic evaluation to investigate low-back pain in a 47-year-old Japanese male. Cholangiocarcinoma was suspected and a left hemihepatectomy performed. Histological examination revealed a 3 × 3.8-mm tumor in the neighboring B2 bile duct. Histological and immunohistochemical investigations revealed the presence of a PEComa and pancreatic acini within the tumor mass. PEComa in the hepatobiliary and pancreatic regions are extremely rare. The presence of heterotopic pancreas is also relatively uncommon. The strong regional association of these 2 lesions raises the possibility of a PEComa originating from heterotopic pancreas or from an irritable response caused by heterotopic pancreas.

To test the sensitivity and specificity of a clinical case definition of acute intussusception in infants to assist health-care workers in settings where diagnostic facilities are not available. Prospective studies were conducted at a major paediatric hospital in Viet Nam (the National Hospital of Pediatrics, Hanoi) from November 2002 to December 2003 and in Australia (the Royal Children's Hospital, Melbourne) from March 2002 to March 2004 using a clinical case definition of intussusception. Diagnosis of intussusception was confirmed by air enema or surgery and validated in a subset of participants by an independent clinician who was blinded to the participant's status. Sensitivity of the definition was evaluated in 584 infants agedclinical features consistent with intussusception but for whom another diagnosis was established (234 infants in Hanoi; 404 in Melbourne). In both locations the definition used was sensitive (96% sensitivity in Hanoi; 98% in Melbourne) and specific (95% specificity in Hanoi; 87% in Melbourne) for intussusception among infants with sufficient data to allow classification (449/533 in Hanoi; 50/51 in Melbourne). Reanalysis of patients with missing data suggests that modifying minor criteria would increase the applicability of the definition while maintaining good sensitivity (96-97%) and specificity (83-89%). The clinical case definition was sensitive and specific for the diagnosis of acute intussusception in infants in both a developing country and a developed country but minor modifications would enable it to be used more widely.

Chronic nonischemic ileo-ileo-colic intussusception

International Nuclear Information System (INIS)

Roic, G.; Posaric, V.; Boric, I.; Vrtar, Z.; Cigit, I.

2005-01-01

Background. Chronic intussusception is a prolapse of a portion of the bowel into the lumen of an immediately adjacent segment of the bowel; it lasts for 14 days or more. The aim of the article is to present a rare cause of nonacute abdominal pain. Case report. We report about 14-year-old girl who presented with a one-month history of intermittent cramping lower abdominal pain and change in bowel behavior. Plain abdominal x-ray, ultrasonography and CT were performed. Laparatomy revealed an ileo-ileo-colic intusussception (70 cm long); invaginated Meckel's diverticulum was a prevailing anomaly. Conclusions. Atypical clinical presentation of chronic intussusception often results in delayed or inadequate management of such cases because of the lack of suspicion of a correct diagnosis. Preoperative diagnosis of invagination was based on ultrasonography and computed tomography (CT) which proved again as the most effective and useful preoperative diagnostic method. Surgical intervention is always needed in adults and older children because of high incidence of underlying lesions in them. (author)

A Unique Surgical Technique for Tracheostomy in Heterotopic Ossification: A Case Report.

Science.gov (United States)

Cheng, Esther; Thorpe, Eric

2016-11-01

To describe a technique for tracheostomy in heterotopic ossification that has not yet been described in the literature. We report a case of difficult tracheostomy while using conventional techniques in a 68-year-old patient who underwent mitral valve replacement requiring warfarin therapy three months prior. Imaging revealed heterotopic ossification overlying the trachea. A literature review was performed to identify similar cases or techniques. Extensive surgical planning was pursued after the initial attempted tracheostomy failed, and the airway was eventually accessed using a lighted intubation stylet for guidance and a drill. Heterotopic ossification has been described after orthopedic and abdominal surgeries. We identified one case report in the literature of tracheostomy performed in the setting of heterotopic ossification by an unspecified mechanism. There are few reported cases of tracheobronchial calcification in cardiac patients receiving warfarin therapy; however, these patients had characteristic imaging findings that were not consistent with those of our patient. We illustrate a safe and effective technique for tracheostomy in heterotopic ossification that has not been reported. Coordination with the anesthesia service was paramount for a successful operation. © The Author(s) 2016.

This study was conducted to evaluate success and perforation rates of pneumatic reduction and to find the predictors of reduction failure. We reviewed 224 cases of pediatric intussusception diagnosed by air-enema between July, 1989 and June, 1992. The mean age was 9.8 months(range, 1 month to 3 years). Logistic regression analysis was used to find predictors of reduction failure. Successful reduction was achieved in 197 cases(87.9% of success rate). Bowel perforation occurred in two cases(0.9% of perforation rate). There were two statistically significant predictors of failure;(1) ileoileocolic intussusception(ρ < .001), (2) long duration of symptom (ρ < .001). Surgery was performed in 26 cases (11.6%), of which seven required bowel resection. Pneumatic reduction is a useful means in the management of pediatric intussusception with a high success rate and no mortality

Full Text Available Gastrointestinal stromal tumours (GISTs are rare tumour. It comprises 0.2% of gastrointestinal tumours and only 0.04% of small intestinal tumours. Usually this tumour is found in people in their 60s.These tumours can be found anywhere in the gastrointestinal tract but most commonly found in the stomach (40–60%. Patients with GISTs usually have vague and nonspecific symptoms. We present a 17year-old with complain of abdominal pain, distension, and few episodes of vomiting. All laboratory investigations were normal. The ultrasonography (USG and computed tomography (CT were suggestive of jejuno-jejunal intussusception. The patient had emergency exploratory laparotomy with resection of the segment with five cm healthy margin, and end to end anastomosis. Patient was discharged after 4 days and remains well.

Full Text Available We report here the case of a 32-year-old man with a history of traumatic brain injury who presented with swelling of his right thigh. Soft tissue ultrasonography performed 3 days after the onset of symptoms showed a heterogeneous hyperechoic lesion with the formation of cysts and hypervascularity in the right iliopsoas abutting the surface of the femoral bone. This became a diffuse echogenic plaque with a posterior acoustic shadowing 12 days later. A diagnosis of heterotopic ossification was made on the basis of the presence of typical ultrasonographic findings and was confirmed by pathology. We emphasize that an early diagnosis of heterotopic ossification can be made with ultrasonography and can lead to early treatment.

Heterotopic ossification (HO) is a well-known complication following the surgical treatment of fractures and dislocations about the elbow but it is not commonly discussed as a complication following arthroscopy. We present a case of a young athlete who developed HO after the arthroscopic treatment of lateral epicondylitis. This is a case report chart review of a 24 year old male with lateral epicondylitis. After failing conservative measures, arthroscopic debridement of the extensor carpi radialis brevis (ECRB) origin ensued. The treatment and patient's final disposition were reported. The patient developed heterotopic ossification of the elbow follow arthroscopic debridement of the ECRB origin. Further surgery was required to excise the heterotopic ossification. Good recovery of motion was achieved. To our knowledge, we present the first case of HO development after elbow arthroscopy for lateral epicondylitis. As the use of elbow arthroscopy continues to grow, there is a need for identification of the risk factors and primary prophylaxis for HO.

Intussusception in children: not only surgical treatment

Anna Maria Caruso

2017-02-01

Full Text Available Introduction: Intussusception is the commonest cause of acute in­testinal obstruction in children. Failure of timely diagnosis and treatment results in a surgical emergency leading to fatal outcome. The classic triad of symptoms is seen in less than one-third of the children affected. Aim of this study was to evaluate the comprehensive management of intussusception in children, evaluating the outcome of conservative treatment with hydrostatic ultrasound reduction and surgery.Material and methods: A retrospective analysis was conducted including pediatric patients (up to 14 years old with diagnosis of bowel intussusception. The management and treatment depended on the patients’ situation: for children in good general conditions initial hydrostatic reduction under continuous ultrasonographic monitoring was attempted; if severe dehydration and/or septic shock was observed, the conservative treatment was contraindicated and direct surgical treatment was performed.Result: A total of 44 pediatric patients were included in the study. The most frequent symptoms observed were paroxysmal abdominal pain (100% of cases and vomiting (72%; only 29% of patients presented with the classic triad of symptoms (abdominal pain, palpable mass and blood stained stools. 28 patients (64% were managed conservatively with ultrasound hydrostatic reduction. 10 patients (23% required primary surgical intervention because of clinical conditions; 6 patients (14% were operated after failure of conservative approach. The total percentage of operated patients was 36%, with lead points identified in 12 cases.Conclusion: Our data confirm that hydrostatic reduction is a simple, real time procedure, free of radiations, non invasive and safe. Age had no impact on the reducibility whereas bloody stool, a prolonged duration of symptoms and the presence of lead point were risk factors of failure.

MRI of laminar heterotopic grey matter

International Nuclear Information System (INIS)

Vahldiek, G.; Terwey, B.; Hanefeld, F.; Sperner, J.

1990-01-01

In one baby and 2 infants who presented with psychomotor retardation and epilepsy laminar heterotopic grey matter was demonstrated via magnetic resonance imaging. Laminar heterotopia is a rare migrational disorder with bilateral symmetric ribbons of grey matter within the centrum semiovale, separated from ventricular walls and from obviously normal-sized cortex by broad layers of white matter. The heterotopic grey matter has a signal intensity which is isointense compared with that of normal cortex irrespective of image weighting. On account of this signal behaviour differentiation against other white matter diseases is easy. The knowledge of these pathognomonic findings facilitates correct diagnosis, especially during the first and the second year of life, when signal intensities of white and grey matter differ from normal findings because of the occasionally delayed myelination process. Therefore, further diagnostic procedures can be avoided and early counseling of parents is possible. (orig.) [de

Ultrasound-guided hydrostatic reduction of intestinal intussusception: description of three cases

Full Text Available With the objective of reporting the technique of ultrasound-guided hydrostatic reduction of intestinal intussusception, three cases with confirmed diagnosis of the disease submitted to reduction with this technique are described. All cases had successful reductions with no complications. One patient experienced a recurrence of the invagination eight days after treatment, which was surgically corrected. The technique of hydrostatic reversal of intestinal intussusception guided by ultrasound may be used in place of the conventional barium enema, since it is a minimally invasive and safe method, with high rates of success and few complications.

Full Text Available Abstract Introduction Heterotopic pancreatic cancer in the duodenum is a very rare disease. Only twelve cases have been reported worldwide to date. We report a rare case of malignant transformation of heterotopic pancreas (Heinrich type III in the duodenum with long-term survival of the patient, and review the 12 cases in the literature. Case presentation A 75-year-old Japanese man was admitted to our hospital complaining of nausea and vomiting. Endoscopy and upper gastrointestinal contrast study showed marked duodenal stenosis. A pylorus-preserving pancreaticoduodenectomy was performed. Histopathological examination of the surgically resected specimen showed malignant transformation of heterotopic pancreas (Heinrich type III in the duodenum. The postoperative course was uneventful, and the patient was discharged from the hospital on postoperative day 30. He is well and shows no signs of recurrence at the time of writing, six years after the surgery. Conclusion Adenocarcinoma arising within the heterotopic pancreas appears to be rare. It is difficult to obtain a correct diagnosis preoperatively. The management of heterotopic pancreas depends on the presence or absence of symptoms. If the patient is asymptomatic or benign, conservative treatment with regular follow-up is recommended. When the patient is symptomatic or there is a suspicion of malignancy, surgical management with intra-operative frozen section diagnosis is indicated.

2018-02-21

To expose our experience in the diagnostic and surgical treatment of neurogenic heterotopic ossification of the hip. We designed an observational retrospective descriptive study including 20 patients (30 hips) with neurogenic heterotopic ossification of the hip secondary to spinal cord injury attended in our institution in the last 10 years, with a minimum of one year follow-up. Medical files and imaging studies were reviewed. The study variables analyzed were: type and localization of neurogenic heterotopic ossification, pre-post excision range of motion, level and aetiology of spinal cord injury, ASIA score, smoking history, surgical approach and complications associated with surgery. A total of 20 patients were treated with resection of heterotopic ossification in 30 hips. 16 patients presented ASIA A spinal cord injury and 4 ASIA B spinal cord injury. Preoperatively all the patients had severe ankylosis in the hip that made sitting in a wheel chair and activities such as repositioning and hygiene difficult. The average postoperative motion at the follow-up evaluation was 90° in flexion, 20° of internal rotation and 40° of external rotation. Immediately after surgery all the patients followed a specific intensive physiotherapy regime for the hip and celecoxib 200 mg was administrated daily orally for a month to prevent recurrence of heterotopic bone formation. None of the patients reviewed suffered a recurrence of heterotopic bone formation. Surgical excision of hip ossification in order to achieve functional ROM of the hip is the best treatment for patients with neurogenic heterotopic ossification of the hip. Copyright © 2018 SECOT.

Alexander L. Dodds

2014-01-01

Full Text Available Although the incidence of minor heterotopic ossification is probably higher than what is usually expected, severe heterotopic ossification (HO is an extremely rare event following total knee replacement surgery. We present the case of a 66-year-old woman who initially had achieved an excellent range of motion following bilateral uncemented rotating platform total knee replacement, before presenting with pain and loss of range of motion at 2 months after surgery. Severe HO was diagnosed on X-rays. Treatment consisted of nonoperative measures only, including physiotherapy with hydrotherapy and anti-inflammatories. She eventually regained her range of motion when seen at 8 months after operation. This case illustrates that nonoperative treatment without the use of radiotherapy or surgery can be used to safely resolve stiffness caused by HO after total knee replacement.

Functioning heterotopic grey matter? Increased blood flow with voluntary movement and sensory stimulation

Heterotopic grey matter has never been reported to have any neuronal function other than as an epileptic focus. However, recent advances in measurement of regional cerebral blood flow (rCBF) and cerebral metabolism have enabled us to assess localised function and functional changes of the brain. We saw a patient with cerebral haemorrhage with bilateral heterotopic grey matter. No neurological deficits or seizures were present before the haemorrhage. To establish the function of the heterotopic grey matter, we studied changes in their rCBF during voluntary movement and sensory stimulation of unilateral extremities using xenon-CT (Xe-CT). (orig.)

Intussusception is commonly seen in infants. It is occasionally found in adults usually due to carcinomas, colonic diverticuli, polyps and rarely Meckel's diverticulum. An adult male presented with upper abdominal pain, nausea, anorexia and loose stools. The initial investigative workup was unremarkable and patient responded to treatment given for acute gastroenteritis. After 3 days, the pain recurred in right iliac fossa with rebound tenderness and leukocytosis. Surgery was performed with provisional diagnoses of acute appendicitis and/or acute Meckel's diverticulitis. Per-operative findings revealed invaginated Meckel's diverticulum causing non-obstructing intussusception. (author)

Intussusception is one of the important causes of intestinal obstruction in children. Hydrostatic reduction under ultrasound guidance is a popular treatment method for intussusception. In the present study, we aimed to explain the demographic characteristics of and treatment approaches in patients diagnosed with intussusception by ultrasound. Forty-one patients diagnosed with intussusception by ultrasound between August 2011 and May 2013 were retrospectively analyzed. Twenty-four of these patients who had no contraindications had been treated with ultrasound-guided hydrostatic reduction. Twenty-four of the patients were male and 17 were female, a 1.4/1 male-to-female ratio. The majority of the patients were between the ages of 6-24 months and 2-5 years. The mean age was 31.12±26.32 months (range 3-125). Patients were more frequently diagnosed in April and May. Seventeen patients who had clinical contraindications enrolled directly for surgery. In 20 of the 24 patients who underwent ultrasound-guided hydrostatic reduction, reduction was achieved. Three experienced recurrence. In two of these patients, successful reduction was achieved with the second attempt. The remaining patient was enrolled for surgery. Hydrostatic reduction was performed 26 times on these 24 patients, and in 22, success was achieved (84.6%). No procedure-related complications occurred in the patients. Ultrasound-guided hydrostatic reduction, with its high success rates and lack of radiation risk, should be the first choice therapeutic approach for children diagnosed with intussusception.

Intussusception reduction: Effect of air vs. liquid enema on radiation dose

Both air and radiopaque liquid contrast are used to reduce ileocolic intussusception under fluoroscopy. Some suggest air lowers radiation dose due to shorter procedure times. However, air enema likely lowers radiation dose regardless of fluoroscopy time due to less density over the automatic exposure control cells. We test the hypothesis that air enema reduction of ileocolic intussusception results in lower radiation dose than liquid contrast enema independent of fluoroscopy time. We describe a role for automatic exposure control in this dose difference. We retrospectively evaluated air and liquid intussusception reductions performed on a single digital fluoroscopic unit during a 26-month period. We compared patient age, weight, gender, exam time of day and year, performing radiologist(s), radiographic image acquisitions, grid and magnification use, fluoroscopy time and dose area product. We compared categorical and continuous variables statistically using chi-square and Mann-Whitney U tests, respectively. The mean dose area product was 2.7-fold lower for air enema, 1.3 ± 0.9 dGy.cm{sup 2}, than for liquid, 3.5 ± 2.5 dGy.cm{sup 2} (P<0.005). The mean fluoroscopy time was similar between techniques. The mean dose area product/min was 2.3-fold lower for air, 0.6 ± 0.2 dGy.cm{sup 2}/min, than for liquid, 1.4 ± 0.5 dGy.cm{sup 2}/min (P<0.001). No group differences were identified in other measured dose parameters. Fluoroscopic intussusception reduction using air enema uses less than half the radiation dose of liquid contrast enema. Dose savings are independent of fluoroscopy time and are likely due to automatic exposure control interaction. (orig.)

Yoon, Chong Hyun; Kim, Han Suk

1986-01-01

Following on from diagnosis using ultrasound, hydrostatic reduction using saline enema under ultrasound guidance was tried in 20 cases of childhood intussusception. The conclusions were as follows: 1. Success rates of saline enema under ultrasound guidance during a first-8 month period (P1) and a second-10 month period (P2) were 55.6% (5/9) and 54.5% (6/11) respectively. Average success rate was 55% (11/20). 2. During the periods of P1 and P2, no case was reduced by barium enema in 6 cases of failed reduction with saline enema. 3. During the period of P2, 5 cases of successful reduction with saline enema were confirmed by clinical follow-up without barium enema. 4. During the periods of P1 and P2, 9 cases of failed reduction with saline enema were operated, resulting in 6 cases of segmental resection and 3 cases of manual reduction. 5. The obvious advantages of this method are: 1. No radiation hazard. 2. No fear of barium peritonitis. 3. Detection of leading point. 6. With above results, this method could completely replace barium enema. And ultrasonography should be the initial study in the evaluation of intussusception in children and then if necessary, saline enema under ultrasound guidance should be done.

2017-09-01

Full Text Available An approximately four-year-old male castrated guinea pig (Cavia porcellus was presented for painful defecation with a 24-hour history of hyporexia and intermittent episodes of rolling behavior. Upon presentation the patient was quiet, alert, and responsive, and mildly hypothermic. Abdominal palpation revealed an approximately 2-cm long oblong mass within the caudal abdomen. Abdominal radiographs revealed gastric dilation without volvulus and a peritoneal mass effect. The patient was euthanized following gastric reflux of brown malodorous fluid from his nares and oral cavity. A necropsy was performed and revealed a jejuno-jejunal intussusception causing mechanical gastrointestinal ileus, and gastric dilatation without volvulus. While non-obstructive gastrointestinal stasis is common and obstructive ileus is uncommon in guinea pigs, this report shows that intestinal intussusception is a differential in guinea pigs with ileus and gastric dilatation.

Data of randomly controlled trials comparing the hydrostatic and pneumatic reduction for intussusception in pediatric patients as initial therapy are lacking. The aim of this study was to conduct a randomly controlled trial to compare the effectiveness and safety of the hydrostatic and pneumatic reduction techniques. All intussusception patients who visited West China Hospital of Sichuan University from January 2014 to December 2015 were enrolled in this study in which they underwent pneumatic reduction or hydrostatic reduction. Patients were randomized into ultrasound-guided hydrostatic or X-ray-guided pneumatic reduction group. The data collected includes demographic data, symptoms, signs, and investigations. The primary outcome of the study was the success rate of reduction. And the secondary outcomes of the study were the rates of intestinal perforations and recurrence. A total of 124 children with intussusception who had met the inclusion criteria were enrolled. The overall success rate of this study was 90.32%. Univariable analysis showed that the success rate of hydrostatic reduction with normal saline (96.77%) was significantly higher than that of pneumatic reduction with air (83.87%) (p=0.015). Perforation after reduction was found in only one of the pneumatic reduction group. The recurrence rate of intussusception in the hydrostatic reduction group was 4.84% compared with 3.23% of pneumatic reduction group. Our study found that ultrasound-guided hydrostatic reduction is a simple, safe and effective nonoperative treatment for pediatric patients suffering from intussusceptions, and should be firstly adopted in the treatment of qualified patients.

Intussusception is a medical emergency that occur with higher frequency in children under 2 years of age. Diagnosis can be difficult as the classical triad of abdominal pain, jelly stools and palpable abdominal mass is seen in less than 50% of the patients. However, the diagnosis of intussusception can be established with variable degree of accuracy using plain abdominal x-ray films, ultrasound, computed tomography or barium (or air/saline) enema. Some of these imaging methods are also useful during treatment of this condition. The authors present a review of the literature and a pictorial essay of the imaging findings in patients with intussusception. In addition, a discussion on the current and controversial issues related to the treatment of intussusception is presented. (author)

2012-05-01

Full Text Available Intussusception is a common surgical disorder in puppies. Double intussusception (DI however, is an extremely rare form of this pathology. The authors report a case of a 3-month-old, Shih-Tzu puppy referred to Veterinary Medical Center of Chungbuk National University, Korea with symptoms of abdominal discomfort, intermittent vomiting and bloody diarrhea for 5 days. Ultrasonographic examination of the left mid-abdominal region revealed a mass with a ‘triple case’ sign completely different from the classic ‘target sign’. The surgical intervention confirmed it to be an ileocecal DI in ascending colon. The case emphasizes the rare ‘triple case’ sign as a descriptive finding on ultrasonography in DI presentations.

An Unusual Complication of an Infiltrated Intravenous Catheter: Heterotopic Ossification in a Newborn

Directory of Open Access Journals (Sweden)

Full Text Available

Heterotopic ossification refers to formation of lamellar  bone in soft tissues. The etiology is diverse and includes genetic, post-traumatic, and metabolic causes. Elicitation of  bone morphogenic proteins are thought to play a key role in the pathogenic process. Initially, heterotopic ossification presents a clinical and radiographic challenge in that it can be mistaken for other more worrisome entities which present with calcified soft tissue masses. However, a spontaneous clinical resolution, temporal relationship to an inciting agent, and radiographic evolution to a peripherally-calcified lesion are all clues to the diagnosis. Here we present the clinical and radiographic features of heterotopic ossification as a result of an infiltrated peripheral IV.

2009-01-01

The aetiology of faecal incontinence is multifactorial, yet there remains an approach to assessment and treatment that focusses on the sphincter. Rectal intussusception (RI) is underdiagnosed and manifests primarily as obstructed defecation. Yet greater than 50% of these patients admit to faecal incontinence on closer questioning. We aimed to evaluate the incidence of RI at evacuation proctography selectively undertaken in the evaluation of patients with faecal incontinence. Patients with faecal incontinence seen in a pelvic floor clinic were evaluated with anorectal physiology and ultrasound. Where the faecal incontinence was not fully explained by physiology and ultrasound, evacuation proctography was undertaken. Studies were classified as 'normal', 'low-grade RI' (recto-rectal), 'high-grade RI' (recto-anal) or 'anismus'. Forty patients underwent evacuation proctography (33 women, 83%). Median age was 63 years (range 34-77 years). Seven patients (17%) had a normal proctogram. Three (8%) had recto-rectal RI. Twenty-five (63%) demonstrated recto-anal RI. Five patients (12%) had anismus. Recto-anal intussusception is common in patients undergoing selective evacuation proctography for investigation of faecal incontinence. The role of recto-anal intussusception in the multifactorial aetiology of faecal incontinence has been largely overlooked. Evacuation proctography should be considered as part of routine work-up of patients with faecal incontinence.

Heterotopic pancreatic tissue of the stomach leading to gastric diverticulum and upper gastro-intestinal bleeding

Directory of Open Access Journals (Sweden)

Silviu Stoian

2016-11-01

Full Text Available Heterotopic pancreatic tissue of the stomach is a rare condition. Gastric diverticulum is also a rare condition, mostly located at the fornix. Therefore, the existence of a pyloric gastric diverticulum containing a submucosal tumor proved to be heterotopic pancreatic tissue of the stomach is an extremely rare condition. The patient was a young thin male with epigastralgia chronically treated for gastritis/ulcer. Following an episode of melena, he underwent gastroscopy that diagnosed antral gastric diverticulum containing a polyp. The lesion was surgically removed. The pathology report stated: heterotopic pancreatic tissue of the stomach with secondary development of a traction diverticulum. Heterotopic pancreas tissue of the stomach is a rare condition but the association with gastric diverticulum is completely unusual. The possibility of the ectopic tissue leading to secondary diverticulum development should be considered.

Intussusception is a common surgical emergency in infants and children. The incidence of intussusception is from one to four per 2,000 infants and children. If there is no peritonitis, perforation sign on abdominal radiographic studies, and nonresponsive shock, nonoperative reduction by pneumatic or hydrostatic enema can be performed. The purpose of this study was to compare the success rates of both the methods. Two institutional retrospective cohort studies were performed. All intussusception patients (ICD-10 code K56.1) who had visited Chiang Mai University Hospital and Siriraj Hospital from January 2006 to December 2012 were included in the study. The data were obtained by chart reviews and electronic databases, which included demographic data, symptoms, signs, and investigations. The patients were grouped according to the method of reduction followed into pneumatic reduction and hydrostatic reduction groups with the outcome being the success of the reduction technique. One hundred and seventy episodes of intussusception occurring in the patients of Chiang Mai University Hospital and Siriraj Hospital were included in this study. The success rate of pneumatic reduction was 61% and that of hydrostatic reduction was 44% (P=0.036). Multivariable analysis and adjusting of the factors by propensity scores were performed; the success rate of pneumatic reduction was 1.48 times more than that of hydrostatic reduction (P=0.036, 95% confidence interval [CI] =1.03-2.13). Both pneumatic and hydrostatic reduction can be performed safely according to the experience of the radiologist or pediatric surgeon and hospital setting. This study showed that pneumatic reduction had a higher success rate than hydrostatic reduction.

CONCLUSION: Bezoars are an extremely rare cause of intussusception in adults. A high level of suspicion needs to exist in the presence of a history of eating dried fruit, history of gastric surgery, diabetes mellitus, and problems with mastication. Various treatment modalities exist to treat obstructions secondary to bezoars, including open reduction and removal of bezoar via enterotomy.

Acute enteritis or gastroenteritis in young dogs as a predisposing factor for intestinal intussusception: a retrospective study.

Science.gov (United States)

Rallis, T S; Papazoglou, L G; Adamama-Moraitou, K K; Prassinos, N N

2000-10-01

Various types of intestinal intussusception were diagnosed in 29 of 220 young dogs with acute enteritis or gastroenteritis, due to canine parvovirus (85 cases) or presumably to other infectious agents, inflammation or less common hypermotility and metabolic derangements (135 cases). As the other causes of the disease were excluded, acute enteritis or gastroenteritis was considered to be the most likely predisposing factor for the intestinal intussusception. The most common type of intussusception was found to be the ileocolic. Of the 21 dogs that underwent surgical resection and anastomosis of the intestine, 18 dogs recovered completely and three died due to complications. The high survival rate was due to the effective pre-operative, surgical and post-operative therapy.

Eray Çaliskan

2012-03-01

Full Text Available The aim of this case report is to present two cases of heterotopic pregnancy in the light of the literature, to present the incidence of heterotopic pregnancy which has increased due to ovulation induction and assisted reproductive techniques and that might cause serious problems for the pregnant women and intrauterine pregnancy. A 33 year old woman who conceived via ovulation induction with gonadotropins and intrauterine insemination was evaluated due to abdominal pain at 6th weeks of gestation. Despite an unknown diagnosis with multidiciplinary approach, she was sent to our center due to acute abdomen with unstable hemodynamic status. The 9 weeks old intrauterine fetus was diagnosed to be dead. She was performed emergency laparotomy salpingectomy for the ruptured tubal pregnancy and she received whole blood transfusions. The postoperative period was uneventhful and she was recovered without any complications. Our second case is a 31 years old woman who conceived via spontaneous cycle. She was evaluated due to abdominal pain at 8th weeks of gestation. Heterotopic pregnancy could have been diagnosed with ultrasonography. She had laparascopic salpingectomy with stable vital signs and stable hemoglobin values. Blood transfusion was not necessary and intrauterine pregnancy was continued with healthy. In women admitting with pelvic pain after conceiving with assisted reproductive techniques, for early diagnosis of heterotropic pregnancy, a carefull ultrasonographic examination of the adnexal regions should be performed and heterotopic pregnancy should be kept in mind for the differential diagnosis of any cystic mass. This approach might help plan the optimum treatment and also minimize the harm to the pregnant women and the intrauterine fetus.

2011-01-01

Full text: Introduction: Metastases from malignant melanoma to the gastrointestinal tract are uncommon. Often found in jejunum and ileum, they are responsible for up to 7% of complications pre mortem. These metastases manifest with bleeding, perforation, obstruction or intussusception and require immediate surgery. Intussusception is a rare finding in the report described and is presented in a double into distinct segments. History and Physical Examination: M.H.C.S, female, 50 years, presenting 3 cm ulcerated lesion in the calcaneous region of the right foot with two years of evolution, no signs of infection or neoplastic permeation shores. Surgical excision of the lesion was performed and histopathologic analysis showed non-classifiable malignant melanoma. Submitted material to immunohistochemistry showed that markers of antigens Melan A and HMB45 positive, favoring the diagnosis of malignant melanoma. Tumor resection with expanding margins and selective inguinal lymphadenectomy through the technique of sentinel node, with rates equal to V Clark and Breslow thickness of 1.3 cm. Patient presented with acute abdominal obstruction treated surgically. Despite an uneventful post-operative, brain metastases developed, and patient is currently undergoing chemotherapy. Complementary Exams: Contrasted abdominal CT showing distension of the small bowel and an image suggestive of double intussusception. Treatment and Results: Indicated that laparotomy confirmed the presence of double intussusception in small intestine, the first being 110 cm from the angle of Treitz with a palpable tumor mass and dilatation of the upstream and the second character equal to 220 cm of the same, treated with bowel resection followed by end anastomosis. The diagnosis of malignant melanoma was confirmed by immunohistochemical analysis of surgical specimens. Discussion/Conclusion: Metastatic lesions in the gastrointestinal tract are often asymptomatic or nonspecific. The diagnosis should be

The conventional hydrostatic reduction of an intussusception with barium enema or the pneumatic reduction of an intussusception is associated with considerable ionizing radiations and a risk of perforation; while the hydrostatic reduction of an intussusception under ultrasound guidance is a very safe method because the whole procedure is visualized with real time ultrasound. Also, being a non-invasive method with a high success rate, this procedure has emerged as a useful alternative to a surgical intervention. The aim of this study was to evaluate the role of ultrasound and colour Doppler studies for the guidance of the hydrostatic reduction of a childhood intussusception by using normal saline. Among 41 children who were evaluated with ultrasonography for the confirmation of the presence of intussusceptions, hydrostatic reduction of intussusception were performed under a sonographic guidance in 30 patients, whereas 11 patients were excluded due to clinical contraindications. This disease was observed mostly at the ages of 6 months to 24 months. In 80% of the patients, there was a recent history of gastroenteritis and 40 % had a history of common cold. The most common site of the intussusception was the transverse colon near the hepatic flexor of the colon (90%), with a mean duration of 22.1±17.3 hours. The overall rate of a successful reduction was 87% and the mean reduction time was 14 minutes. None of the cases showed recurrence within 24 hrs. No complications were observed. We conclude that ultrasound with colour Doppler study is very useful for the diagnosis of intussusceptions, as well as for guided hydrostatic reductions by using normal saline enema. This is an optimal, simple, and a safe procedure for the treatment of intussusceptions in paediatric patients.

Heterotopic ossification of the elbow after closed reduction and retrograde intramedullary nailing for radial neck fracture treated by anconeus interposition.

Sreenivas, T; Menon, Jagdish; Nataraj, A R

2013-12-01

Heterotopic ossification around the elbow can lead to considerable functional disability. We describe a case of a 42-year-old man who developed heterotopic ossification of his elbow after closed reduction of the elbow dislocation and radial neck fracture and retrograde intramedullary nailing for radial neck fracture. During the follow-up after initial surgery, movements of the elbow were gradually deteriorated and diagnosed as heterotopic ossification of the elbow. Implant removal, radial head excision along with heterotopic mass, and also interposition of the anconeus muscle resulted in improvement of his elbow mobility. At 18 months of follow-up, patient had elbow flexion arc of 15°-110°, 70° of supination, and 50° of pronation without recurrence of heterotopic ossification. The uniqueness of this case lies in the treatment of heterotopic ossification of the elbow to prevent its recurrence, which was developed after retrograde intramedullary nailing for radial neck fracture following closed reduction.

Esophageal heterotopic gastric mucosa in esophageal atresia

Directory of Open Access Journals (Sweden)

Lachlan J.R. Harrison

2018-05-01

Full Text Available Heterotopic gastric mucosa (HGM is occasionally found at endoscopy in the proximal esophagus of adults and children, when it manifests as an asymptomatic small island of reddish pink mucosa just below the upper esophageal sphincter. There are few reports of esophageal HGM detected by endoscopy after repair of esophageal atresia (EA with tracheo-esophageal fistula (TEF. We report a child with multiple patches of HGM in the proximal and distal esophagus seen at endoscopy after EA/TEF repair. No obvious symptoms were related to the HGM and she remains under endoscopic surveillance. The incidence of esophageal HGM may be increased in patients with EA and its distribution can be more extensive than a simple “inlet patch”. There is evidence to suggest that esophageal HGM increases the risk of developing Barrett's esophagus and has a malignant potential. Heterotopic gastric mucosa extends the spectrum of potential pathologies affecting the esophagus in patients with EA/TEF and supports current international guidelines for endoscopic surveillance of these patients.

2011-09-01

Full Text Available Abstract Introduction The initial diagnosis of intussusception in adults very often can be missed and cause delayed treatment and possible serious complications. We report the case of an adult patient with complicated double ileoileal and ileocecocolic intussusception. Case presentation A 46-year-old Caucasian man was transferred from the gastroenterology service to the abdominal surgery service with severe abdominal pain, nausea, and vomiting. An abdominal ultrasound, barium enema, and abdominal computed tomography scan revealed an intraluminal obstruction of his ascending colon. Plain abdominal X-rays showed diffuse air-fluid levels in his small intestine. A double ileoileal and ileocecocolic intussusception was found during an emergent laparotomy. A right hemicolectomy, including resection of a long segment of his ileum, was performed. The postoperative period was complicated by acute renal failure, shock liver, and pulmonary thromboembolism. Our patient was discharged from the hospital after 30 days. An anatomical pathology examination revealed a lipoma of his ileum. Conclusions Intussusception in adults requires early surgical resection regardless of the nature of the initial cause. Delayed treatment can cause very serious complications.

A 27-year-old man with recurrent right lower quadrant pain was admitted to our hospital. Ultrasonography and computed tomography examination of the abdomen revealed a target sign in the ascending colon, which was compatible with the diagnosis of cecal intussusception. The intussusception was spontaneously resolved at that time, but it relapsed 6 mo later. The patient underwent a successful colonoscopic disinvagination; there was no evidence of neoplastic or inflammatory lesions in the colon and terminal ileum. The patient underwent laparoscopic surgery for recurring cecal intussusception. During laparoscopy, we observed an unfixed cecum on the posterior peritoneum (i.e. a mobile cecum). Thus, we performed laparoscopic appendectomy and cecopexy with a lateral peritoneal flap using a barbed wound suture device. The patient's post-operative course was uneventful, and he continued to do well without recurrence at 10 mo after surgery. Laparoscopic cecopexy using a barbed wound suture device is a simple and reliable procedure that can be the treatment of choice for recurrent cecal intussusception associated with a mobile cecum.

2013-01-01

Full Text Available Mucosa associated lymphoid tissue (MALT lymphomas are rare neoplasms. They are most common in the stomach followed by small intestine and colon. The symptoms are nonspecific and generally do not present with intussusception. Here we report a rare clinical entity in which a 35-year-old female presented to the emergency with severe abdominal pain which was sudden in onset. History revealed that she had been having vague mild abdominal pain for 2 years. Ultrasonography showed ileocolic intussusception with hypoechoic lesion of 54 × 46 mm seen at the lead point. Emergency laparotomy with the right hemi-colectomy was done. The specimen was sent for histopathological examination which revealed a diagnosis of MALT lymphoma. Awareness of the varied clinical presentation helps in formulating the appropriate therapeutic strategy.

2002-01-01

Ileocolic invagination is the penetration of an ileum segment into the right colon. Four cases of ileocolic intussisception are described by US and CT with its surgical pathologic confirmation. Three different patterns are described by CT which reflect its severity and duration. These are: target, in layers and kidney form. Ultrasound signs are: 'pseudo kidney', 'target' and 'donut crescent' being the latter the only distinctive sign. Flow suggests that the intussusception could be reductable. The presence of fluid in peritoneal cavity could mean ischemia and irreductibility. (author)

Retrospective hospital based surveillance of intussusception in children in a sentinel paediatric hospital: benefits and pitfalls for use in post-marketing surveillance of rotavirus vaccines.

Lloyd-Johnsen, C; Justice, F; Donath, S; Bines, J E

2012-04-27

Evaluation of the safety of rotavirus vaccines, particularly with respect to the risk of intussusception, is recommended for countries planning to introduce rotavirus vaccines into the National Immunisation Program. However, as prospective studies are costly, require time to conduct and may be difficult to perform in some settings, retrospective hospital based surveillance at sentinel sites has been suggested as an option for surveillance for intussusception following introduction of rotavirus vaccines. To assess the value of retrospective hospital based surveillance to describe clinical and epidemiological features of intussusception in children aged <24 months and to investigate any temporal association between receipt of a rotavirus vaccine and intussusception. A retrospective chart review of all patients diagnosed with intussusception at Royal Children's Hospital, Melbourne, Australia over an 8-year period including before and after rotavirus vaccine introduction into the National Immunisation Program, was conducted using patients identified by a medical record database (ICD-10-CM 56.1). Patient profile, clinical presentation, treatment and outcome were analysed along with records of immunisation status obtained using the Australian Childhood Immunisation Register. A 9% misclassification rate of discharge diagnosis of intussusception was identified on critical chart review. The incidence rate of intussusception at the Royal Children's Hospital over the study period was 1.91 per 10,000 infants <24 months (95% CI 1.65-2.20). Intestinal resection was required in 6.5% of infants (95% CI 3.6%, 11.0%). Intussusception occurred within 30 days after vaccination in 2 of 27 patients who had received at least 1 dose of a rotavirus vaccine. Valuable data on the incidence, clinical presentation and treatment outcomes of intussusception can be obtained from data retrieved from hospital medical records in a sentinel paediatric hospital using standardised methodology. However

Extra-pulmonary tuberculosis (TB) is more common in renal allograft recipients and may present with dissemination or an atypical features. We report a renal allograft recipient with intestinal TB presenting 3 years after transplantation with persistent fever, weight loss, diarrhea, abdominal pain and mass in the abdomen with intestinal obstruction. He was diagnosed to be having an ileocolic intussusception which on resection showed a granulomatous inflammation with presence of acid-fast bacilli (AFB) typical of Mycobacterium tuberculosis. In addition, AFB was detected in the tracheal aspirate, indicating dissemination. He received anti-TB therapy (ATT) from the fourth postoperative day. However, he developed a probable immune reconstitution inflammatory syndrome (IRIS) with multiorgan failure and died on 11(th) postoperative day. This is the first report of intestinal TB presenting as intussusception in a renal allograft recipient. The development of IRIS after starting ATT is rare in renal allograft recipients. This report highlights the need for a high index of suspicion for diagnosing TB early among renal transplant recipients and the therapeutic dilemma with overwhelming infection and development of IRIS upon reduction of immunosuppression and starting ATT.

Full Text Available Introduction. Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant. This is a report of a case of jejunojejunal intussusception secondary to non-Hodgkin’s B-cell lymphoma in an adult patient. Case Presentation. A 74-year-old male with no previous significant medical history presented with symptoms of acute intestinal obstruction. A CT scan of the abdomen and pelvis revealed 2 areas of jejunojejunal intussusception, which were surgically managed successfully. Histopathological examination of the specimen revealed the presence of high grade diffuse large B-cell-type non-Hodgkin’s lymphoma, and the patient was referred to the oncology team for further management. Discussion. B-cell lymphoma is a rare but well-documented cause of intussusception in adults, with most cases being at the ileocolic region. We present a rare case of jejunojejunal intussusception as the initial presentation of non-Hodgkin’s B-cell lymphoma in an adult patient.

Full Text Available Abstract Background Colonic intussusception is a rare congenital abnormality, mostly manifesting before the age of two with abdominal pain and acute intestinal obstruction with or without bleeding. In adults it may occur idiopathically or due to an intraluminal tumor mass. Case presentation A 25-year-old man presented with an acute abdomen and severe crampy abdominal pain. The clinical picture mimicked acute appendicitis. Transabdominal ultrasound examination revealed a 5 cm circular mass in the right upper abdomen. The ensuing computed tomography suggested an intussusception in the ascending colon. Intraoperatively, no full thickness invagination was detected. Due to a hard, intraluminal tumor a standard right hemicolectomy with ileotransversostomy was performed. The histopathological analysis revealed a cystic colon duplication leading to mucosal invagination and obstruction. Conclusions In adults, colon intussusception is a rare event causing approximately 1% of all acute intestinal obstructions. Unlike its preferentially nonsurgical management in children, a bowel intussusception in adults should be operated because an organic, often malignant lesion is present in most cases.

Small intestine intussusception in adults is a rare condition mainly caused by primary or metastatic small intestine malignancy. Here, we present a 72-year-old male patient who was diagnosed with small intestine cancer that was presented as small intestine intussusception on hybrid {sup 18}F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT). The patient was initially referred for an abnormality on a chest radiography and severe anemia. FDG PET/CT showed the lung lesion in the right upper lobe of lung as a high FDG uptake mass. Accidentally, FDG PET demonstrated another intense hypermetabolic intraluminal lesion in the small intestine accompanied with intussusception shown as a circumferential hypermetabolic wall. By pathologic examination, the patient was diagnosed as primary small intestine cancer with lung metastasis. This case highlights usefulness of hybrid FDG PET/CT to identify unexpected malignancy.

Purpose. - To report the results of postoperative radiation therapy in preventing the development of heterotopic bone formation after hip replacement surgery in high-risk patients. Patients and methods. - Between 1991 and 2007, 44 patients were preventively treated with postoperative RT after total hip replacement. In total, 47 hips were treated. All patients were considered at high risk for developing heterotopic bone formation. Most patients (63.5%) were treated because of a history of severe osteoarthritis or ankylosing spondylitis. All patients were treated with shaped parallel-opposed fields with a single fraction of 7 Gy using 6 or 18 MV photons. Most patients (94%) received radiation therapy within 72 hours postoperative and in only three patients radiation therapy was delivered after 72 hours post-surgery (5-8 days). Results. - Minimum follow-up was 1 year. There were 18 females and 26 males. Median age was 63 years (range: 18-80). Treatments were well tolerated and no acute toxicity was seen post-radiation therapy. Only one of the 47 hips (2%) developed heterotopic bone formation. This patient received postoperative radiation therapy to both hips but only developed heterotopic bone formation in one of them. None of the three patients treated beyond 72 hours failed. To date no late toxicity has been observed. Conclusion. - The use of postoperative radiation therapy was an effective and safe treatment in the prevention of heterotopic bone formation in a high-risk group of patients undergoing total hip replacement.

A quadriplegic patient with a swollen leg was suspected of having deep-venous thrombosis, and was studied with radionuclide venography (RNV) and contrast venography. Focal narrowing of the femoral vein, seen on RNV, was due to extrinsic compression. Although soft-tissue radiographs were normal, Tc-99m diphosphonate imaging established the diagnosis of early heterotopic bone formation (myositis ossificans), which was responsible for the venous compression. Clinically this inflammatory process can mimic deep-venous thrombosis, and should be considered in evaluating patients at risk for both heterotopic bone formation and deep-venous thrombosis

Patients receiving heterotopic (''piggyback'') cardiac transplants, when the patient's own and transplanted donor hearts are connected in parallel, present special problems in determining their relative contributions to total cardiac function. Three patients who had transplants because of intractable heart failure were studied using first pass and gated equilibrium technetium-99m-labeled blood pool scintigraphy. In one patient, thallium-201 myocardial perfusion scans were obtained. These nuclear cardiology techniques provided anatomic and functional information noninvasively that proved helpful in patient management

To identify changes in gray and white matter concentrations (GMC, WMC), and their relation to heterotopic neuron numbers in mesial temporal lobe epilepsy (mTLE). The gray matter or white matter concentrations of 16 left and 15 right mTLE patients who achieved an excellent surgical outcome were compared with those of 24 healthy volunteers for the left group and with 23 healthy volunteers for the right group, by optimized voxel-based morphometry using unmodulated and modulated images. A histologic count of heterotopic neurons was obtained in the white matter of the anterior temporal lobe originating from the patients' surgical specimens. In addition, the number of heterotopic neurons were tested to determine if there was a correlation with the GMC or WMC. The GMCs of the left and right mTLE groups were reduced in the ipsilateral hippocampi, bilateral thalami, precentral gyri, and in the cerebellum. The WMCs were reduced in the ipsilateral white matter of the anterior temporal lobe, bilateral parahippocampal gyri, and internal capsules, but increased in the pons and bilateral precentral gyri. The heterotopic neuron counts in the left mTLE group showed a positive correlation (r = 0.819, p < 0.0001) with GMCs and a negative correlation (r = - 0.839, p < 0.0001) with WMCs in the white matter of the anterior temporal lobe. The present study shows the abnormalities of the cortico-thalamo- hippocampal network including a gray matter volume reduction in the anterior frontal lobes and an abnormality of brain tissue concentration in the pontine area. Furthermore, heterotopic neuron numbers were significantly correlated with GMC or WMC in the left white matter of anterior temporal lobe.

Full Text Available Jejunogastric intussusception is a rare event following gastrointestinal reconstruction. We present a case report in which jejunogastric intussuception was diagnosed in a child four years after a gastrectomy with jejunogastric reconstruction for duodenal duplication. Prompt diagnosis and emergent resection of any non-viable bowel, and revision to a Roux-En-Y anastomosis with or without pexy of the Roux limb to the colon or Y-limb mesentery appear to be the appropriate treatment for this clinical entity.

Full Text Available Shigella enteritis remains an important cause of mortality and morbidity in all age groups, in developing as well as developed countries. Owing to the emerging resistance to multiple antibiotics among Shigella spp., it has been recognized as a major global public health concern and warrants constant monitoring of its resistance pattern. We report a case of segmental ileitis caused by non.-ESBL producing multidrug resistant Shigella flexneri in an infant clinically mimicking intussusception, which was effectively treated by ceftriaxone.

The bone matrix of growing rats was labeled by multiple injections of 3H-proline, and demineralized bone matrix (DBM) was prepared. The DBM was allotransplanted heterotopically into growing rats. New bone formation was induced in and around the implants. The new bone formation was accompanied by a decrease in the content of 3H; 20 and 30 days after implantation, 72% and 46%, respectively, of the activity remained in the implants. Daily injections of indomethacin (2 mg/kg) inhibited calcium uptake by about 20% at 20 and 30 days and inhibited the release of 3H from the DBM to a similar degree. Heterotopic bone induction by DBM is accompanied by matrix resorption, and inhibition of the new bone formation decreases the resorption of DBM

Full Text Available We report a case of congenital heterotopic salivary gland with draining sinus in the lower neck on the right side of a 10-year-old female, which we initially thought to be a branchial fistula. Heterotopic salivary glands are rare lesions in the neck and when present appear very similar to branchial cleft sinus or fistula. This congenital lesion is rare. This is probably the first report from India. It is important to report this case to raise the awareness of this condition.

The recent classification as threatened status of the northern koala (Phascolarctos cinereus) by the Australian Government highlights the importance of the conservation and health management of this iconic Australian marsupial. This case series describes gastrointestinal torsion and intussusception in six northern koalas (three males, three females, 2-11 yr old) at the San Diego Zoo from 1976 to 2012. Two koalas died shortly after presentation. Diagnoses of ileocecal intussusception, resulting from enteritis in one case and cecal torsion in the other, were made at postmortem examination. One koala died 4 days after an exploratory laparotomy, with negative findings, and an acute double colonic intussusception was diagnosed at postmortem examination. Two small intestinal mesenteric torsion and one proximal colon mesenteric torsion cases were successfully corrected surgically. In the case of colonic mesenteric torsion, the koala had recurrent clinical signs 2 wk later, and a second surgery requiring resection and anastomosis of ischemic jejunum was performed, with the koala dying shortly afterward. One koala with small intestinal torsion had a recurrence of torsion 22 mo later and subsequently died. The koala with the second case of small intestinal torsion remains alive 14 mo postsurgical correction. All six koalas presented with signs of colic that included anorexia, lethargy, depression, acute abdominal distension, abdominal stretching, decreased fecal output, open-mouth gasping, or a combination of symptoms. Abdominal radiographs may show stacked gastrointestinal linear gas patterns and contrast stasis. Prevalence of torsion and intussusception is low at this institution (2%), although recurrence in individuals is common (50%) and overall survival is poor (83%), which emphasizes the importance of timely recognition, surgical correction, and postoperative management. While inciting etiologies were unable to be determined in these cases, monitoring generalized

Although the gastrointestinal tract is a fairly frequent site of melanoma metastases, reports of small bowel intussusception caused by melanoma are very rare. We report the case of a 77-year-old man who was admitted to our hospital with epigastric pain, melena and anaemia. After clinical examination, laboratory evaluation and radiological work-up the diagnosis of a jejunal intussusception was made. Exploratory laparoscopy revealed a large tumour arising from the jejunum, approximately 20 cm distal to the angle of Treitz. Small bowel resection with an end-to-end anastomosis was performed. Histological examination showed an intestinal melanoma. There are different theories concerning the origin of malignant melanoma in the small bowel. Although the small and large intestines normally contain no melanocytes, these cells have occasionally been found in the alimentary and respiratory tracts and even in lymph nodes, which supports the theory of a primary origin of melanoma at these sites. Since this was a solitary intestinal lesion and there was no history of cutaneous melanoma, we conclude that this could be an example of a very rare primary melanoma of the small intestine.

To investigate the risk of intussusception after monovalent rotavirus vaccine (RV1) given to infants aged 2 and 3 months in England. Hospital Episode Statistics (HES) were used to identify infants aged 48-183 days admitted between 11/03/2013 and 31/10/2014 with intussusception. Diagnosis was confirmed from medical records and HES procedure codes. Vaccination status was obtained from general practitioners. The risk of admission within 1-7 and 8-21 days of vaccination was analysed using the self-controlled case-series (SCCS) method with age effect adjustment by including historical data before RVI introduction in July 2013. A total of 119 cases were identified during the study period and intussusception confirmed in 95 of whom 39 were vaccinated 1-21 days before onset. An increased relative incidence (RI) in this period was found, 4.53 (95% confidence interval 2.34-8.58) and 2.60 (1.43-4.81) respectively after the 1st and 2nd doses with an attributable risk of 1.91 and 1.49 per 100,000 doses respectively. The peak risk was 1-7 days after the first dose, RI 13.81 (6.44-28.32), with an estimated 93% of the 15 cases being vaccine-attributable. Mean interval between onset and admission, and clinical features were similar between vaccine-associated and background cases. Despite intussusception being a contraindication to rotavirus vaccination, 10 infants received a further dose; none had a recurrence. The RIs in a meta-analysis combing our results with Australia, Mexico, Brazil and Singapore using RV1, a 2, 4 month schedule and SCCS gave pooled RI estimates of 2.35 (1.45-3.8) and 1.77 (1.29-2.43) in the 21 day period after the 1st and 2nd doses, respectively. The earlier age at the 2nd dose in England did not affect the risk. We estimate that the RVI programme causes around 21 intussusception admissions annually in England but, since it prevents around 25,000 gastro-intestinal infection admissions, its benefit/risk profile remains strongly positive.

To describe the presence of heterotopic gastric mucosa forming an abscess associated with acute abdominal pain and shock in a puppy. A 7-month-old male intact Shih-Tzu was presented to the emergency service for evaluation of a 12-hour history of vomiting and lethargy progressing to weakness. On presentation, the puppy was obtunded and hypotensive. Radiographs revealed an ill-defined mid-ventral abdominal mass. Ultrasound revealed an echogenic, fluid-filled mass associated with the jejunum. The puppy had an exploratory celiotomy and a 2 × 4 cm oval fluid-filled soft tissue mass was found to be intimately associated, but not communicating with, a section of the mid-jejunum. The mass and associated jejunum were removed via enterectomy. Histopathology of the resected mass revealed heterotopic gastric mucosa; bacterial culture of the fluid contained in the mass revealed heavy growth of Escherichia coli. The puppy recovered from surgery, was discharged from the hospital, and has had no further complications from this episode. Heterotopic gastric mucosa is commonly found incidentally on necropsy. When it has been associated with acute gastrointestinal signs, mechanical intestinal obstruction with or without perforation was noted. To the authors' knowledge, this is the first reported case of heterotopic gastric mucosa leading to abscess formation and acute abdominal pain in the dog. © Veterinary Emergency and Critical Care Society 2014.

Full Text Available Intussusception is common cause of bowel obstruction in the paediatric age group compared to the elderly population. Many times, The diagnosis may be difficult because of asymptomatic nature of thisbowel disorder. We hereby describe the case of a 75-year-old male who presented with lethargy, weakness,loss of movement in the joints and was found to be anemic. The haemoglobin level was low so he wastransfused with packed cells. On gastrointestinal (GI endoscopy, upper GI bleed was observed. A mass was observed beyond ampulla at the 2nd and 3rd part of the duodenal junction. Computerized tomography (CTscan also showed a mass at the head of pancreas and the lesion at the left lung. In view of persistent bleed,‘Whipple’s procedure’ was performed. Histopathological examination showed small cell carcinoma of the lungs with metastasis to the pancreas and the jejunum. We here discuss the case of intussusception with intestinal metastasis which presented with gastrointestinal bleeding.

Traumatic neglected dislocations of hip in children are rare entity. Neglected traumatic dislocations of hip in children along with heterotopic ossification are still rare. Post traumatic neglected hip dislocations are to be diagnosed as early as possible and have to be treated with precision and aggression as the outcome of treatment for the same is not predictable. 5 year female with post-traumatic neglected hip dislocation with heterotopic ossification forming a pseudoacetabulum postero-superiorly in which femur head was lodged. The girl was operated by open reduction using Moore's Posterior approach and showed good results. Here is a mention of a rare case with a good 18 months follow up with no complication. Post-traumatic neglected posterior hip dislocation mostly requires open reduction and relocation of femoral head in original acetabulum with concentric reduction. Heterotopic ossification is a rare but known complication of traumatic dislocation of hip in children. Good results can be achieved in such cases and regular follow-up of patient is required post-operatively.

Midgut pain due to an intussuscepting terminal ileal lipoma: a case report.

LENUS (Irish Health Repository)

Abbasakoor, Noormuhammad O

2010-01-01

ABSTRACT: INTRODUCTION: The occurrence of intussusception in adults is rare. The condition is found in 1 in 1300 abdominal operations and 1 in 100 patients operated for intestinal obstruction. The child to adult ratio is 20:1. CASE PRESENTATION: A 52-year-old Irish Caucasian woman was investigated for a 3-month history of intermittent episodes of colicky midgut pain and associated constipation. Ileocolonoscopy revealed a pedunculated lesion in the terminal ileum prolapsing into the caecum. Computed tomography confirmed a smooth-walled, nonobstructing, low density intramural lesion in the terminal ileum with secondary intussusception. A laparoscopic small bowel resection was performed. Histology revealed a large pedunculated polypoidal mass measuring 4 x 2.5 x 2 cm consistent with a submucosal lipoma. She had complete resolution of her symptoms and remained well at 12-month follow-up. CONCLUSION: This case highlights an unusual cause of incomplete small bowel obstruction successfully treated through interdisciplinary cooperation. Ileal lipomas are not typically amenable to endoscopic removal and require resection. This can be successfully achieved via a laparoscopic approach with early restoration of premorbid functioning.

Does Excision of Heterotopic Ossification of the Elbow Result in Satisfactory Patient-Rated Outcomes?

Sandeep, K N; Suresh, G; Gopisankar, B; Abhishek, N; Sujiv, A

2017-03-01

Treatment of heterotopic ossification (HO) of the elbow is challenging and fraught with complications. Patients who sustain direct trauma to the elbow joint, the central nervous system, and thermal burns are at increased risk for development of HO. There is a paucity of studies and reports on patient's self-evaluation after the excision of the heterotopic ossification. This retrospective study assessed outcomes after excision of heterotopic ossification around the elbow in a cohort of ten patients operated from 2012 to 2015. The outcome assessment was done by the Mayo Elbow Performance index (MEPI) and the American Shoulder and Elbow Surgeons-Elbow score (ASES-E scores). The mean follow-up was 18.11 months after the operation. The Mayo Elbow Performance Score was excellent in two elbows, good in six and fair in two. The mean gain in flexion-extension arc after excision of HO was 80 degrees. All of the patients had residual flexion deformity postoperatively. Eight of the nine patients were able to do activities requiring flexion at final follow-up. Excision of HO around the elbow is associated with satisfactory patient-rated outcomes in spite of failure to regain full range of motion.

Heterotopic cardiac transplantation decreases the capacity for rat myocardial protein synthesis

Klein, I.; Samarel, A.M.; Welikson, R.; Hong, C.

Heterotopic cardiac isografts are vascularly perfused hearts that maintain structural and functional integrity for prolonged periods of time. When placed in an infrarenal location, the heart is hemodynamically unloaded and undergoes negative growth, leading to cardiac atrophy. At 7 and 14 days after transplantation, the transplanted heart was decreased in size compared with the in situ heart (p less than 0.001). To assess the possible mechanism(s) to account for this reduction in size we studied in vivo rates of total left ventricular (LV) protein synthesis, total LV RNA content, and 18S ribosomal RNA content by nucleic acid hybridization. The LV protein synthetic rate was 4.7 and 5.3 mg/day in the in situ heart and was significantly decreased to 2.9 and 2.7 mg/day in the transplanted hearts at 7 and 14 days, respectively. LV RNA content of the transplant declined to 53% and 48% of the in situ value at 7 and 14 days, respectively. Hybridization studies revealed that LV 18S ribosomal subunit content was reduced proportionately to total RNA in the heterotopic hearts. As a result of these changes, there was no significant difference in the efficiency of total LV protein synthesis between the in situ and transplanted hearts. The present studies demonstrate that the hemodynamic unloading and cardiac atrophy that is characteristic of heterotopic cardiac transplantation is accompanied by a decrease in LV total RNA content and 18S RNA, resulting in a decreased capacity for myocardial protein synthesis

In 20 patients with paralysis, 25 regions were irradiated with (mostly) 10 Gy in single fractions of 2 to 2.5 Gy using 8 MW photons. In 15 patients radiotherapy was performed as a primary treatment in the status of myositis; 7 patients were treated after (subtotal) resection of already manifest ossifications (2 patients were treated twice, primarily and postoperatively). In a minimum follow-up 12 weeks, none of the 20 irradiated patients showed any progression of the developing or already manifest ossification; thus mobilisation and rehabilitation could be carried out as desired. No side effects occurred. The preliminary results of the present study suggest that radiotherapy is an effective local treatment with minimal side effects for the prevention of heterotopic bone formation in patients with paraplegia.

The effect of vitamin D deficiency unhampered by hypocalcemia on de novo bone formation was studied in guinea pigs. Heterotopic induction of osteogenesis was evaluated 4 weeks after intramuscular transplantation of allogenic urinary bladder transitional epithelium from vitamin-D-repleted (+D) donors into +D and -D recipients. In -D recipients the frequency of osteogenesis and the amount of induced bone were significantly diminished; induced bone was less mature, scantly cellular woven bone poorly repopulated with bone marrow. No effect of vitamin D deficiency on orthotopic bone growth and on mineralization of orthotopic and heterotopically induced bone was observed. It is proposed that in addition to inducing factors (BMPs, growth factors) which may be responsible for transformation of mesenchymal cells to osteoprogenitor cells, normal concentrations of 1,25-(OH)2D3 may be required for proliferation and further differentiation of these cells into osteoblasts and for expression of genes engaged in extracellular matrix formation and maturation.

Heterotopic ossification (HO)--the formation of bone in soft tissues--is a frequent problem after surgery of the hip and pelvis, but little is known about its underlying pathogenic mechanisms. It is vital to study the underlying pathogenesis in animal models to develop and evaluate new prophylactic regimens directed against HO. However, previously developed small-animal models for the study of HO imitate neither surgery nor trauma-mechanisms that potentially cause HO. Hence, the goal of this study was to develop a novel small-animal model imitating hip surgery that can reliably produce HO. Twenty male Wistar rats were subjected to surgery of the right hip during which the femoral canal was reamed in three steps up to 2 mm, and a muscle lesion was made. Twelve weeks after surgery, the amount of heterotopic bone was assessed using micro-computed tomography. Eighteen of 20 animals showed HO around the hip 12 weeks after surgery. The amount of heterotopic bone varied from very small particles up to near ankylosis. A rat model of hip/pelvic surgery that does not use exogenous osteogenic stimulus and can reliably produce HO was developed.

Heterotopic ossification is a complication of total hip arthroplasty in 14 to 30% of patients. Significant functional impairment will occur in up to 28% of patients with ectopic bone. The high risk group includes those with preexisting heterotopic bone in either hip, those suffering from hypertrophic osteoarthritis or ankylosing spondylitis and patients who have had multiple procedures on the hip. Fifty-eight patients (67 hips) were irradiated after surgical removal of ectopic bone (53 hips) or received radiation prophylaxis of heterotopic ossification (14 hips). Ninety-five percent of patients had either no bone visible or insignificant amounts of ectopic bone visible on postoperative hip X-rays. Only 5% of patients showed significant persistence of ectopic bone. Postoperative hip function was dramatically improved compared to preoperative function in all patients treated. The importance of early commencement of irradiation is emphasized

Extensive heterotopic gastric mucosa of the small intestine is a rare, but potentially life-threatening condition characterized by multifocal or long-segment heterotopic gastric mucosa within the bowel lumen that is often associated with other anomalies including malrotation and annular pancreas. Although the imaging findings are characteristic, this entity may be unrecognized due to its unusual imaging appearance and rarity. CT or MR enterography and {sup 99m}Tc-sodium pertechnetate scintigraphy can provide complementary information that enables specific diagnosis and accurate assessment of disease extent. We present a case of extensive heterotopic gastric mucosa of the small intestine imaged by simultaneous, combined {sup 99m}Tc-sodium pertechnetate single photon-emission computed tomography (SPECT)/CT enterography to both familiarize the reader with the condition and describe an imaging strategy that enables specific diagnosis and assists with treatment planning.

Heterotopic ossifications in a mouse model of albright hereditary osteodystrophy.

David L Huso

Full Text Available Albright hereditary osteodystrophy (AHO is characterized by short stature, brachydactyly, and often heterotopic ossifications that are typically subcutaneous. Subcutaneous ossifications (SCO cause considerable morbidity in AHO with no effective treatment. AHO is caused by heterozygous inactivating mutations in those GNAS exons encoding the α-subunit of the stimulatory G protein (Gα(s. When inherited maternally, these mutations are associated with obesity, cognitive impairment, and resistance to certain hormones that mediate their actions through G protein-coupled receptors, a condition termed pseudohypoparathyroidism type 1a (PHP1a. When inherited paternally, GNAS mutations cause only AHO but not hormonal resistance, termed pseudopseudohypoparathyroidism (PPHP. Mice with targeted disruption of exon 1 of Gnas (Gnas(E1-/+ replicate human PHP1a or PPHP phenotypically and hormonally. However, SCO have not yet been reported in Gnas(E1+/- mice, at least not those that had been analyzed by us up to 3 months of age. Here we now show that Gnas(E1-/+ animals develop SCO over time. The ossified lesions increase in number and size and are uniformly detected in adult mice by one year of age. They are located in both the dermis, often in perifollicular areas, and the subcutis. These lesions are particularly prominent in skin prone to injury or pressure. The SCO comprise mature bone with evidence of mineral deposition and bone marrow elements. Superficial localization was confirmed by radiographic and computerized tomographic imaging. In situ hybridization of SCO lesions were positive for both osteonectin and osteopontin. Notably, the ossifications were much more extensive in males than females. Because Gnas(E1-/+ mice develop SCO features that are similar to those observed in AHO patients, these animals provide a model system suitable for investigating pathogenic mechanisms involved in SCO formation and for developing novel therapeutics for heterotopic bone

Intussusception in children is a common abdominal emergency. Recent years have brought a New promising method of nonsurgical invagination treatment, hydrostatic reduction under sonographic (US) guidance. The major advantage of this method is lack of the ionized radiation. The aim of our study is to asses the safety and effectiveness of hydrostatic reduction under US guidance used as a first choice method of invagination treatment in our department. >From July 2006 to December 2007, 33 procedures of hydrostatic reduction under US guidance were performed in 27 children, aged from 7 months to 6 years and 10 months. The procedure was performed in US room by radiologist and surgeon with the use of self-constructed set for saline enema. The sedation of patient was routinely performed. The initial procedure was effective in 23 patients (pts) (85%). In 5 pts the recurrence of intussusception occurred and in 3 of them next attempt of the reduction was successful. In 4 cases the initial procedures failed, and those children were operated. Total amount of 6 pts underwent an operation. We do not observe any complications connected with the procedure. Hydrostatic reduction of children intusussception under US-guidance is safe and effective method. Our initial results meet the recommended limits of successful reduction rates. It encouraged us to evaluation and further implementation of this method. Water enema is a first choice method of invagination treatment in our hospital. (authors)

Henoch-Schönlein purpura (HSP) is systemic vasculitis disease with various clinical manifestations. Gastrointestinal symptoms in patients with HSP are usually common, with an incidence rate of 62-90%. Most of these gastrointestinal symptoms occur after typical skin purpura, which is a very important clinical evidence for making a diagnosis of HSP. It is difficult to diagnose HSP without skin rash. About 25% of patients may experience gastrointestinal symptoms as their first symptoms. Herein, we report a case of ileo-colic intussusception associated with HSP in a 5-years-old girl presented with diffuse abdominal distension. Our patient did present any symptoms of HSP, such as purpura, arthralgia or arthritis, before surgery.

Sabater, Mikel; Huynh, Minh; Forbes, Neil

2015-03-01

A 23-year-old male tawny eagle (Aquila rapax) was examined because of sudden onset of lethargy, regurgitation, and hematochezia. An intestinal obstruction was suspected based on radiographic findings, and an ileo-ceco-rectal intussusception was confirmed by coelioscopy. A 14.3-cm section of intestine was resected before an intestinal anastomosis was done. Coelomic endoscopic examination confirmed a postsurgical complication of adhesions between the intestinal anastomosis and the dorsal coelomic wall, resulting in a partial luminal stricture and requiring surgical removal of the adhesions. Rectoscopy was useful in diagnosing a mild luminal stricture related to the second surgery. Complete recovery was observed 2 months after surgery. Lack of further complications in the 2 years after surgery demonstrates good tolerance of intestinal resection and anastomosis of a large segment of bowel in an eagle. This report is the first reported case of intussusception in an eagle and emphasizes the potential use of endoscopic examination in the diagnosis as well as in the management of complications.

Long-Term Symptoms Onset and Heterotopic Bone Formation around a Total Temporomandibular Joint Prosthesis: a Case Report

Directory of Open Access Journals (Sweden)

Luca Guarda-Nardini

2014-04-01

Full Text Available Background: The literature on total alloplastic temporomandibular joint (TMJ reconstructions is encouraging, and studies on total alloplastic TMJ replacements outcomes showed acceptable improvements in terms of both pain levels and jaw function. Nevertheless, some adverse events, such as heterotopic bone formation around the implanted prosthesis, may occur. In consideration of that, the present manuscript describes a case of heterotopic bone formation around a total temporomandibular joint prosthesis, which occurred several years after the implant. Methods: The present manuscript describes a case of heterotopic bone formation around a total TMJ prosthesis, which occurred several years after the implant in patients, who previously underwent multiple failed TMJ surgeries. Results: Ten years after the surgical TMJ replacement to solve an ankylotic bone block, the patient came to our attention again referring a progressive limitation in mouth opening. A computerized tomography showed evidence of marked heterotopic bone formation in the medial aspects of the joint, where a new-born ankylotic block occupied most part of the gap created by resecting the coronoid process at the time of the TMJ prosthesis insertion. Conclusions: Despite this adverse event has been sometimes described in the literature, this is the first case in which its occurrence happened several years after the temporomandibular joint replacement. It can be suggested that an accurate assessment of pre-operative risk factors for re-ankylosis (e.g., patients with multiple failed temporomandibular joint surgeries and within-intervention prevention (e.g., strategies to keep the bone interfaces around the implant separated should be better standardized and define in future studies.

The purpose of this project was to implement a protocol facilitating discharge from the emergency department (ED) after successful radiologic ileocolic intussusception reduction in a pediatric referral center. A multidisciplinary team identified drivers for successful quality improvement including educational brochures, a standardized radiologic report, an observation period in the ER with oral hydration challenges, and follow-up phone calls the day after discharge. Patient outcomes were tracked, and quarterly feedback was provided. Of 80 patients identified over a 24-month period, 34 (42.5%) did not qualify for discharge home due to need for surgical intervention (n = 9), specific radiologic findings (n = 11), need for additional intravenous hydration (n = 4), or other reasons (n = 7). Of 46 patients who qualified for discharge, 30 (65.2%) were successfully sent home from the ED. One patient returned with recurrent symptoms that required repeat enema reduction. Sixteen patients were observed and discharged within 23 hours. Adherence with discharge from the ED improved over time. Discharge from the ED was associated with cost savings and improved net margins at the hospital level for each encounter. A sustainable multidisciplinary quality improvement project to discharge intussusception patients from the ED after air-contrast enema reduction was successfully integrated in a high-volume referral center through education, standardized radiologic reporting, and protocoled follow-up.

Daniel Rusiecki

2016-06-01

Full Text Available Lhermitte-Duclos disease (LDD, a disorder first described by French physicians Lhermitte and Duclos in 1920 [25], is a benign, slow growing dysplastic gangliocytoma of the cerebellum, characterized by replacement of the granule cell layer by abnormal granule and Purkinje like cells. The most frequent presenting signs and symptoms are megalocephaly, increased intracranial pressure, nausea, hydrocephalus, ataxia, gait abnormalities, and intermittent headaches, all of which are attributed to the mass effect [6,11,25]. Many cases are associated with a mutation in the phosphatase and tensin homolog or PTEN gene which is also involved in numerous otherwise unrelated central nervous system abnormalities, namely Cowden syndrome [1,6,11], autism spectrum disorder [18], cerebral cortical dysplasia [11,30] and Bannayan-Riley-Ruvalcaba syndrome [30]. The presence of cortical heterotopia has been reported in a small number of LDD cases [3,5,17,32]. We describe a unique case of LDD with cerebral cortical heterotopic grey matter containing neurofibrillary tangles.

Full Text Available Introduction: Heterotopic pregnancy is a life threating condition of intrauterine and extrauterine gestations which occur at the same time. We report a delayed diagnosed case of heterotopic pregnancy. Case: A 31 year-old primigravida was referred to our Emergency Gynaecology Service complicated by acute abdomen. She had been treated with clomiphene citrate and on admission intrauterine a missed abortus of about 8 weeks complicated by a large subchorionic hematoma was detected. Emergency laparotomy was performed because of diffuse intra-abdominal haemorrhage. A right-sided ectopic focus was recognized and excised, and dilatation - curettage was performed. Coclusion: Delay in diagnosing the condition can be fatal to both the mother and the intrauterine fetus. [J Contemp Med 2013; 3(3.000: 207-208

Intussusception as clinical presentation of primary non-Hodgkin lymphoma of the colon in a HIV-patient

Directory of Open Access Journals (Sweden)

Marcelo Corti

Full Text Available Intestinal intussusception rarely occurs in the adult population and accounts only for 1% to 5% of all the causes of intestinal obstruction. This complication is more frequent in the small bowel and can be due to different aetiologies, including inflammatory, infectious or neoplastic diseases. Malignancies account for 50% to 60% of all cases of colon invagination. The gastrointestinal (GI tract is the most common site for extra-nodal non-Hodgkin lymphomas (NHL, representing 5% to 20% of all the cases. However, primary NHL of the GI tract is a very infrequent clinic-pathological entity and accounts only for 1% to 4% of all the neoplasms of the GI tract. Primary NHL of the colon is a rare disease and it comprises only 0.2% to 1.2% of all colonic malignancies. Here we describe a case of an AIDS adult patient who developed an intussusception secondary to a primary large B cell lymphoma of the transverse colon. English and Spanish literature was reviewed.

AIM: To investigate the effect and mechanism of acupuncture at heterotopic acupoints on jejunal motility, particularly in pathological conditions. METHODS: Jejunal motility was assessed using a manometric balloon placed in the jejunum approximately 18-20 cm downstream from the pylorus and filled with approximately 0.1 mL warm water in anesthetized normal rats or rats with diarrhea or constipation. The heterotopic acupoints including LI11 (Quchi), ST37 (Shangjuxu), BL25 (Dachangshu), and the homotopic acupoint ST25 (Tianshu), and were stimulated for 60 s by rotating acupuncture needles right and left at a frequency of 2 Hz. To determine the type of afferent fibers mediating the regulation of jejunal motility by manual acupuncture, the ipsilateral sciatic A or C fibers of ST37 were inactivated by local application of the A-fiber selective demyelination agent cobra venom or the C fiber blocker capsaicin. Methoctramine, a selective M2 receptor antagonist, was injected intravenously to identify a specific role for M2 receptors in mediating the effect of acupuncture on jejunal motility. RESULTS: Acupuncture at heterotopic acupoints, such as LI11 and ST37, increased jejunal motility not only in normal rats, but also in rats with constipation or diarrhea. In normal rats, manual acupuncture at LI11 or ST37 enhanced jejunal pressure from 7.34 ± 0.19 cmH2O to 7.93 ± 0.20 cmH2O, an increase of 9.05% ± 0.82% (P acupuncture at LI11 or ST37 increased intrajejunal pressure from 8.17 ± 0.31 cmH2O to 9.86 ± 0.36 cmH2O, an increase of 20.69% ± 2.10% (P 0.05), respectively. In contrast, acupuncture ST25, a homotopic acupoint, decreased not only intrajejunal pressure, but also significantly decreased frequency in normal rats and rats with constipation or diarrhea. Following demyelination of Aδ fibers, acupuncture at ST37 again augmented intrajejunal pressure to 121.48% ± 3.06% of baseline. Following capsaicin application for 24 h, acupuncture at ipsilateral ST37 increased

Full Text Available Heterotopic grafting sites can be useful in producing oocytes for in vitro Fertilization, therefore, maximising the oocyte yield from the graft by gonadotrophin stimulation would be advantageous. The aim of this study was to investigate the number and quality of oocytes collected from heterotopic autografted ovary after Pregnant Mare Serum Gonadothropin (PMSG induction. Graft recipients were treated either with or without PMSG stimulation 48 hours prior to graft collection. Ovarian tissue from four weeks old mice (DDY strain were autotransplanted under the kidney capsule of the same ovariectomized mice and the oocytes were collected 21 days after autotransplantation. The results showed that the average number of oocytes collected from autografted ovaries without PMSG induction were 9.0. ± 2.8 not significantly different with those received PMSG induction, 10.9 ± 5.1. The percentage of matured and fertilized oocytes and the developed embryos from the autografted ovaries without PMSG induction were 52.4, 33.4, and 26.0%, respectively not significantly different with those received PMSG induction, 53.2, 35.1, and 29.9%, respectively. The number of oocytes and the capacity to matured, fertilized and developed were significantly lower (P < 0.05 compared to the superovulated nongrafted (control ovaries. In conclusion, PMSG induction on the graft recipients did not significantly increase oocytes yield from grafted heterotopic ovaries. The number and quality of oocytes produced from the autografted ovaries were lower than the superovulated nongrafted ovaries, but still can be used for in vitro embryo production after sequential in vitro maturation and fertilization.

Menke, Jan; Kahl, Fritz

2015-03-01

In children with ileocolic intussusception sonography is increasingly being used for diagnosis, whereas fluoroscopy is frequently used for guiding non-invasive reduction. This study assessed the success rate of radiation-free sonography-guided hydrostatic reduction in children with ileocolic intussusception, using novel well-defined success rate indices. All children were evaluated who presented from 2005 to 2013 to the local university hospital with ileocolic intussusception. The patients were treated with sonography-guided hydrostatic reduction unless primary surgery was clinically indicated. The according success rate was determined by indices of Bekdash et al. They represent the ratio of persistently successful non-surgical reductions versus four different denominators, depending on including/excluding cases with primary surgery and including/excluding cases requiring bowel resection/intervention. Fifty-six consecutive patients were included (age, 3 months to 7.8 years). About 80% of the patients presented until 24 h and 20% until 48 h after the onset of symptoms. Seven patients underwent primary surgery, with bowel resection required in three cases. Hydrostatic reduction was attempted in 49 patients, being permanently successful in 41 cases (selective reduction rate 41/49 = 83.7%; crude reduction rate 41/56 = 73.2%). The remaining eight patients underwent secondary surgery, with just two patients not requiring surgical bowel resection/intervention (corrected selective reduction rate 41/43 = 95.3%). The composite reduction rate was 87.2% (successful/feasible reductions, 41/47). Radiation-free sonography-guided hydrostatic reduction has a good success rate in children with ileocolic intussusception. It may be particularly valuable in centers that are already experienced with using sonography for the diagnosis.

During the period between January 1985 and December 1987, barium reduction was performed in 146 cases of intussusception who were admitted to Kwangju Christian Hospital. The results were as follows: 1. Success rate to the symptom duration is relatively constant. 2. The success rate in infants with severe dehydration was 50% but it was gradually increased in infants with moderate dehydration and in infants with mild dehydration, 83.3% and 100% respectively. 3. The success rate of 12 cases in severely dehydrated infants with positive dissection sign was 16.7%. 4. The success rate of 15 cases in moderately dehydrated infants with positive dissection sign was 66.7%. 5. The average time requirement for barium reduction was 58.3 minutes. No serious complications were noted during barium reduction, except mild vomiting. 6. With above results, it is desirable that barium reduction should be performed according to the patient's physical status and radiologic findings.

Full Text Available Abstract Background Symptomatic heterotopic ossification (HO in multiple trauma patients may lead to follow up surgery, furthermore the long-term outcome can be restricted. Knowledge of the effect of surgical treatment on formation of symptomatic heterotopic ossification in polytrauma is sparse. Therefore, we test the effects of surgical treatment (plate osteosynthesis or intramedullary nailing on the formation of heterotopic ossification in the multiple trauma patient. Methods We retrospectively analysed prospectively documented data of blunt multiple trauma patients with long bone fractures which were treated at our level-1 trauma centre between 1997 and 2005. Patients were distributed to 2 groups: Patients treated by intramedullary nails (group IMN or plate osteosynthesis (group PLATE were compared. The expression and extension of symptomatic heterotopic ossifications on 3-6 months follow-up x-rays in antero-posterior (ap and lateral views were classified radiologically and the maximum expansion was measured in millimeter (mm. Additionally, ventilation time, prophylactic medication like indomethacine and incidence and correlation of head injuries were analysed. Results 101 patients were included in our study, 79 men and 22 women. The fractures were treated by intramedullary nails (group IMN n = 50 or plate osteosynthesis (group PLATE n = 51. Significantly higher radiologic ossification classes were detected in group PLATE (2.9 ± 1.3 as compared to IMN (2.2 ± 1.1; p = 0.013. HO size in mm ap and lateral showed a tendency towards larger HOs in the PLATE group. Additionally PLATE group showed a higher rate of articular fractures (63% vs. 28% in IMN while IMN demonstrated a higher rate of diaphyseal fractures (72% vs. 37% in PLATE; p = 0.003. Ventilation time, indomethacine and incidence of head injuries showed no significant difference between groups. Conclusion Fracture care with plate osteosynthesis in polytrauma patients is associated with

Non-hereditary heterotopic ossification (NHHO) may occur after musculoskeletal trauma, central nervous system (CNS) injury, or surgery. We previously described circulating osteogenic precursor (COP) cells as a bone marrow-derived type 1 collagen + CD45 + subpopulation of mononuclear adherent cells that are able of producing extraskeletal ossification in a murine in vivo implantation assay. In the current study, we performed a tissue analysis of COP cells in NHHO secondary to defined conditions, including traumatic brain injury, spinal cord injury, cerebrovascular accident, trauma without neurologic injury, and joint arthroplasty. All bone specimens revealed the presence of COP cells at 2-14 cells per high power field. COP cells were localized to early fibroproliferative and neovascular lesions of NHHO with evidence for their circulatory status supported by their presence near blood vessels in examined lesions. This study provides the first systematic evaluation of COP cells as a contributory histopathological finding associated with multiple forms of NHHO. These data support that circulating, hematopoietic-derived cells with osteogenic potential can seed inflammatory sites, such as those subject to soft tissue injury, and due to their migratory nature, may likely be involved in seeding sites distant to CNS injury.

Bone morphogenetic protein-induced heterotopic bone formation: What have we learned from the history of a half century?

Directory of Open Access Journals (Sweden)

Takenobu Katagiri, PhD

2015-05-01

Full Text Available Bone morphogenetic protein (BMP was originally discovered by Marshall Urist a half century ago following the observation of a unique activity that induced heterotopic bone formation in skeletal muscle tissue. The molecular mechanisms underlying the induction of heterotopic bone formation in skeletal muscle by BMPs were elucidated through the purification and molecular cloning of BMPs and identification of their functional receptors and downstream effectors, as well as from genetic disorders related to BMP activity. BMPs are important regulators of not only skeletal development and regeneration but also the homeostasis of normal skeletal muscle mass. There is still much to learn about the physiology and pathology at the interface of BMPs and skeletal muscle.

Purpose: In vivo data employing a rat model, suggest equivalent suppression of ectopic bone formation by single-fraction irradiation given either pre (≤4 h)- or post (≤24 h)-surgery. Two subsequent randomized clinical trials, from tertiary academic centers with robust experience in heterotopic bone prophylaxis, have reached similar conclusions. To assess the transferability of the above data to the community setting we reviewed our rural community hospital experience with pre- and postoperative radiation prophylaxis. Methods and Materials: Between 11/90 and 6/96, 16 surgerized hips with high risk of heterotopic bone formation received 7.00-8.00 Gy in one fraction either preoperatively (≤4 h) (n = 9) or postoperatively (≤3 days for six hips; day 7 for one hip) (n = 7). Initial patients were routinely treated postoperatively. In late 1992, treatment preference was switched to preoperative irradiation in response to evolving data. The two groups were similar with respect to age, sex, nature of surgery, presurgical Brooker and Harris scores, and in U. of Rochester risk classification distribution. Irradiation was given via 4-20 MV photons through equally weighted AP:PA portals to the periacetabular tissues and proximal one third to one-half of the femoral component. Radiation dose, energy, portal, and blocking design were all similar for the two groups. Hip radiographs were obtained immediately postsurgery and at last follow-up: Delta grades (Brooker grade at follow-up--Brooker grade immediately postsurgery) were computed. Harris scale scores of hip function and movement were assigned via personal interviews and examinations performed prior to irradiation and at last follow-up. Results: All 16 hips are evaluable. Follow-up interval among the post-operative group (mean = 39.8 months; range 18.6-65.8) was significantly longer than among the preoperative group (mean = 20.4 months; range 8.6-41.3) (p < 0.02). The mean Delta grade among the postoperative and

Extremity trauma, spinal cord injuries, head injuries, and burn injuries place patients at high risk of pathologic extraskeletal bone formation. This heterotopic bone causes severe pain, deformities, and joint contractures. The immune system has been increasingly implicated in this debilitating condition. This review summarizes the various roles immune cells and inflammation play in the formation of ectopic bone and highlights potential areas of future investigation and treatment. Cell types in both the innate and adaptive immune system such as neutrophils, macrophages, mast cells, B cells, and T cells have all been implicated as having a role in ectopic bone formation through various mechanisms. Many of these cell types are promising areas of therapeutic investigation for potential treatment. The immune system has also been known to also influence osteoclastogenesis, which is heavily involved in ectopic bone formation. Chronic inflammation is also known to have an inhibitory role in the formation of ectopic bone, whereas acute inflammation is necessary for ectopic bone formation.

Heterotopic ossification is an uncommon disorder that consists of deposition of ectopic bone outside the extraskeletal tissues. In the skin, it can be primary, in association with genetic syndromes, or be secondary to different disorders. The latter include subcutaneous ossification of the legs in chronic venousinsufficiency, an infrequent and unrecognized complication. We report the case of a patient with subcutaneous ossification of both legs secondary to venous insufficiency and review the literature.

1997-01-01

Purpose/Objective: We report our preliminary results of a randomized trial comparing one single dose of 400 cGy versus 700 cGy given postoperatively in an attempt to prevent heterotopic ossification after total hip arthroplasty. Materials and Methods: From 09/1993 and 05/1996, over 800 total hip replacements were performed at our hospital. From this group of patients, 120 hips in 114 high-risk patients (14%) were enrolled in a randomized trial to determine if 400 cGy (Group A) is as efficacious as 700 cGy (Group B) in preventing heterotopic ossification. In Group A, there were 42 males (46 hips) and 12 females (12 hips) with a mean age of 60 (range 41-79); with 18 primary cementless femoral components (33%), 30 primary cemented stems (55%) and 10 revisions. In Group B, there were 30 males (32 hips) and 30 females (31 hips) with a median age of 59 (range 41-85); with 12 primary cementless femoral components (20%), 44 primary cemented stems (73%) and 6 revisions. All acetabular components were of the cementless type. Patients were randomized to receive either 400 cGy or 700 cGy in one fraction. Radiotherapy is given within 48 hours post-operatively using paired anterior and posterior fields, with blocking of the cementless acetabular component and the femoral component. Results: All 114 patients were available for a minimum follow-up of 6 months (range 6-30 months). None of the arthroplasties has failed at the latest follow-up. There were no radiation therapy complications noted. Statistical analysis revealed no difference in the distribution of patients in either group according to age, sex, primary or revision arthroplasty, cemented or cementless femoral component fixation, preoperative heterotopic ossification risk, or surgical approach. Of the 58 hips in Group A, heterotopic ossification was graded as Grade 0 in 24 hips, Grade I in 10 hips, Grade II in 18 hips, Grade III in 6 hips, with no cases of Grade IV. Of the 63 hips in Group B, heterotopic ossification was

Heterotopic pregnancy refers to the simultaneous development of an intrauterine pregnancy and an extrauterine pregnancy. We experienced a case of a ruptured heterotopic pregnancy for a patient with a history of a right segmental salpingectomy from an ectopic pregnancy. The 30-year-old patient with amenorrhea for six weeks complained of lower abdominal pain with hypovolemic shock. Transabdominal ultrasonography showed diffuse hemoperitoneum with a structure similar to an ectatic tube or a deformed cyst with no echogenic double ring or peripheral hypervascularity in the right adnexa and an intrauterine gestational sac. We considered a ruptured corpus luteum cyst as an ultrasonographic finding and found a ruptured tubal mass in the right salpinx and hemoperitoneum through an emergency laparotomy. We performed a right salpingectomy, and the histopathologic report confirmed ectopic pregnancy.

Trauma-Induced Heterotopic Ossification Regulates the Blood-Nerve Barrier

Directory of Open Access Journals (Sweden)

Zbigniew Gugala

2018-06-01

Full Text Available De novo bone formation can occur in soft tissues as a result of traumatic injury. This process, known as heterotopic ossification (HO, has recently been linked to the peripheral nervous system. Studies suggest that HO may resemble neural crest-derived bone formation and is activated through the release of key bone matrix proteins leading to opening of the blood-nerve barrier (BNB. One of the first steps in this process is the activation of a neuro-inflammatory cascade, which results in migration of chondro-osseous progenitors, and other cells from both the endoneurial and perineurial regions of the peripheral nerves. The perineurial cells undergo brown adipogenesis, to form essential support cells, which regulate expression and activation of matrix metallopeptidase 9 (MMP9 an essential regulatory protein involved in opening the BNB. However, recent studies suggest that, in mice, a key bone matrix protein, bone morphogenetic protein 2 (BMP2 is able to immediately cross the BNB to activate signaling in specific cells within the endoneurial compartment. BMP signaling correlates with bone formation and appears critical for the induction of HO. Surprisingly, several other bone matrix proteins have also been reported to regulate the BNB, leading us to question whether these matrix proteins are important in regulating the BNB. However, this temporary regulation of the BNB does not appear to result in degeneration of the peripheral nerve, but rather may represent one of the first steps in innervation of the newly forming bone.

2018-05-09

A 19-year-old woman presented with a 3-month history of an enlarging lesion on the proximal aspect of the femur. After imaging studies and a biopsy had been performed, the mass was determined to represent heterotopic ossification (HO). The only known risk factor was a history of concussion. The mass was resected and, as of the 12-month follow-up, had not recurred. HO is a potentially serious complication of ossification in soft tissues that can develop secondary to several disease states; it commonly occurs following traumatic brain injury. To our knowledge, this is the only case report that describes HO associated with a concussion and no other risk factors.

Full Text Available We report a case of isolated ossification of iliopsoas with ankylosis of the left hip in a 27-year-old female. The patient was diagnosed to have Moyamoya disease, a rare chronic occlusive disorder of cerebrovascular circulation following an acute onset of hemiplegia. The patient presented 9 months later to us with ankylosis of left hip which was successfully treated by surgical excision of the heterotopic bone and there was no recurrence at the end of 5 years. A review of literature failed to reveal a similar case with isolated and complete ossification of iliopsoas muscle associated with Moyamoya disease which required surgical intervention. Surgical excision resulted in dramatic improvement in the quality of life. Surgical excision of neurogenic type of heterotopic ossification is a very successful procedure and timely intervention after maturity of mass is very important to prevent the onset of secondary complications and to avoid recurrence.

Full Text Available Life after severe burns is conditioned by the remaining sequelae. The pathophysiology and risk factors of Heterotopic Ossification (HO after burns are still poorly understood. The aim of this study was to determine: 1 the incidence of HO after burns and 2 the risk factors associated with HO development, in a large retrospective study.A case-control study of patients admitted to the burns intensive care unit of Percy Hospital, Paris, from the 1st January 2009 to the 31st December 2013 and then admitted to one of three centres specialised in the rehabilitation of patients with burns. Multivariate analysis was carried out to analyse the relationship between HO development and demographic and clinical data.805 patients were included. 32 patients (4.0% developed a total of 74 heterotopic ossifications, that is a little higher incidence than the incidence found in the literature. The epidemiological characteristics of the population studied was similar to the literature. HOs were mainly localized around the elbows, followed by the hips, shoulders and knees. Each case-patient was paired with 3 control-patients. There were significant associations between HO development and the length of stay in the burns intensive care unit, the extent and depth of the burns, the occurrence of pulmonary or cutaneous infections, use of curare and use of an air-fluidized bed.In addition to recognized risk factors (duration of stay in the intensive care burns unit, extent and depth of burns, pulmonary and cutaneous infections, the use of curare and the use of a fluidized bed (with the duration of use were significantly associated with HO formation.

2002-01-01

The radiotherapy (RT) in the case of non-malignant diseases is a subject of controversial standpoints. If founds increasingly restricted application in the English-American countries, while it is quite frequently applied treatment in other countries. At the present stage the indications for RT for non-malignant diseases are rather diverse. The heterotopic ossification (HO) refers to the clearly established in clinical practice cases. The present review considers in detail the frequency of HO development after endo-prosthetics, traumas in the area of the cerebrum and the spinal cord, cauterization. The aetiology, pathogenesis and early diagnostics as well as the basic therapeutic possibilities (non-steroid and anti-inflammatory remedies and radiotherapy) have been considered. The radiobiological mechanism of RT action, the type of the used radiation, the time of application (prior-to and post operation RT), doses and schemes of treatment have been analyzed in detail. The use of RT is recommended as a simple for performance and effective local treatment of HO, with absent or negligible side effects. The one-time prior-to and post operation irradiation is more preferable than the fractionated prior-to and post operation one, taking under consideration the comfort of the patients and the possible post operation complications.(author)

UK intussusception audit: A national survey of practice and audit of reduction rates

International Nuclear Information System (INIS)

Hannon, Edward; Williams, Rhianydd; Allan, Rosemary; Okoye, Bruce

2014-01-01

Aim: To define current UK reduction practice and the reductions rates achieved. Materials and methods: Electronic surveys were sent to radiologists at 26 UK centres. This assessed methods of reduction, equipment, personnel, and protocol usage. Standardized audit proforma were also sent to evaluate all reductions performed in 2011. Results: Twenty-two of 26 centres (85%) replied. All used air enema under fluoroscopic guidance. Equipment was not standardized but could be broadly categorized into hand-pumped air-supply systems (seven centres) and pressurized air systems (15 centres). Seventeen centres followed a protocol based on British Society of Paediatric Radiologists (BSPR) guidelines. In 21 of the 22 centres a consultant paediatric radiologist led reductions and only 12 centres reported a surgeon being present. Three hundred and ten cases were reported across 22 centres. Cases per centre ranged from 0–31 (median 14). Reduction rates varied from 38–90% (median 71%). The overall perforation rate was 2.5%. Caseload did not significantly correlate with reduction rate, and there was no significant difference between the two types of equipment used. Median reduction rates were 15% higher in centres with a surgeon present at reduction (p < 0.05). Conclusion: Intussusception care in the UK lacks standardization of equipment and personnel involved. National reduction rates are lower than in current international literature. Improved standardization may lead to an improvement in reduction rates and a surgeon should always be present at reduction

Prior studies have demonstrated the effectiveness of postoperative radiation therapy (RT) to the hip area following total hip replacement (THR) surgery in preventing the development of heterotopic bone formation in patients considered to be at high risk for development of this complication. Previously, patients received 20.00 Gy in 10 fractions (fx) over 2 weeks, beginning as soon postop as medically feasible (usually post-op day 2). In an effort to reduce hospital stay and risk of secondary malignancy, a prospective treatment program was initiated April 1982 using a reduced dose of 10.00 Gy in 5 fx over 5-7 days. As of February 1984, 46 consecutive hips determined to be at high risk were treated with this reduced dose. Prior studies have demonstrated that heterotopic bone is always radiographically evident by 8 weeks. Of the 46 hips, 41 had been evaluated with the minimum required 8 week follow-up X ray. Twenty-five of these hips, 61%, had a mean long term follow-up of 12 months. It historical control group, consisting of 54 consecutive high risk post-THR's, was shown to have a 68.5% incidence of heterotopic bone. The 20.00 Gy group, when RT was started by post-op day 5, demonstrated a 3.2% incidence, compared to 4.9% in the 10.00 Gy group. Complication rates were also comparable in the two RT groups, 19.4% and 7.3% respectively; 10.00 Gy is apparently as effective as 20.00 Gy in preventing heterotopic bone formation in high risk post-THR patients

Purpose: Two prospective trials were undertaken to assess the comparative efficacy of early postoperative irradiation with different radiation doses versus the postoperative use of nonsteroidal antiinflammatory drugs (NSAID) for prevention of heterotopic ossification (HO) following prothetic total hip replacement (THP). Patients and Method: Between 1992 and 1994 585 patients received THP. These patients were randomized in two longitudinal studies each with 3 treatment arms comparing postoperative irradiation with 4x3 Gy (101 patients), 1x5 Gy (93 patients), 1x7 Gy (95 patients) and the postoperative use of the NSAID indometacin for 7 days (113 patients) respectively for 14 days (90 patients) and acetyl salicyl acid (ASS) for 14 days (93 patients). Heterotopic ossification was scored according to the Brooker grading system. One hundred patients receiving no prophylactic therapy after total hip arthroplasty between 1988 and 1992 were analysed and defined as historical control group. Conclusion: Prophylactic irradiation of the operative site after hip replacement is more effective than the use of NSAID. Because no significant difference between the fractionated single dose irradiation was found and the latter is more comfortable for patients and more economical, irradiation with single 7 Gy fraction should be prefered.

Purpose: Experimental and clinical data support effectiveness of perioperative radiotherapy to prevent heterotopic ossification after hip surgery or trauma. Since 1987, two prospectively randomized trials were performed in patients with high-risk factors to develop heterotopic ossification: the first (HOP 1) to assess the prophylactic efficacy of postoperative low vs. medium dose radiotherapy, and the second (HOP 2) to assess the prophylactic efficacy of pre vs. postoperative radiotherapy. Methods and Material: 410 patients with high risk to develop heterotopic ossifications about the hip following hip surgery were recruited. Between June 1987 and June 1992, 249 patients were randomized in HOP 1 to postoperative 'low dose' (5 x 2 Gy; total: 10 Gy) or 'medium dose' (5 x 3.5 Gy; total: 17.5 Gy) radiotherapy. Between July 1992 and December 1995, 161 patients were randomized in HOP 2 to either 1 x 7 Gy preoperatively (≤4 h before surgery) or 5 x 3.5 Gy (total: 17.5 Gy) postoperatively (≤96 h after surgery). With exception of age and type of implant (cemented vs. uncemented prosthesis) all confounding patient variables (gender, prior surgery) and predisposing risk factors were similarly distributed between both trials and treatment arms. Portals encompassed the peri acetabular and intertrochanteric soft tissues. Radiographs were obtained prior and immediately after surgery and at least 6 months after surgery to assess the extent of ectopic bone formation about the hip. Modified Brooker grading was used to score the extent of heterotopic ossification. Harris scoring was applied to evaluate the functional hip status. If the scores decreased from immediate post or preoperative status, respectively, to the last follow-up, radiological or functional failures were assumed. Results: Effective prophylaxis was achieved in 227 (91%) hips of HOP 1 and in 142 (88%) of HOP 2. In HOP 1, 15 (11%) radiological failures were observed in the low-dose group compared to 7 (6%) in the

Degenerative changes and cell death in long-living homo- and heterotopic transplants from embryonic germ layers of rat neocortex.

2003-09-01

Morphological study of allotransplants of rat embryonic neocortex 14-18 months after transplantation into the neocortex, lateral cerebral ventricle, and sciatic nerve of adult animals revealed death of nerve and glial cells in the delayed postoperation period independently on the site of transplantation. After heterotopic transplantation the count of degenerated neurons was 2 times higher that after homotopic transplantation. In heterotopic transplants a considerable number of grafted neurons underwent reversible and irreversible degenerative changes accompanied by their premature aging. Neuronal death is probably determined by insufficiency of trophic influence from afferent structures and target tissues. We hypothesized that antiapoptotic preparations can be used for prevention of transplanted cell death. It was also found that degeneration of neurons was associated with impaired vascularization of transplants and pronounced immune reaction of the recipient in late posttransplantation period. Transplantation of embryonic brain structures can serve as a model system in studies concerning involutive and pathological processes in the central nervous system and in the search for factors improving survival of neurons.

Full Text Available Thyroid heterotopic bone formation (HBF in goiter is a rare finding. Five thyroid resection specimens were analyzed for HBF. The results were correlated with clinicomorphological features. All patients were women (33–82 years. The preoperative diagnosis was thyroid goiter or nodule. Treatment consisted in thyroidectomy and lobectomy (3 and 2, resp.. Microscopy showed sporadic nodular goiter. Malformative blood vessels and vascular calcifications were seen in intra- and extrathyroid location (5 and 3, resp.. The number and size of HBFs (total: 28 ranged between 1 and 23/thyroid gland (one bilateral and 1 and 10 mm, respectively. Twelve HBFs were in contact with the thyroid capsule. Most were extranodular (21, versus 6 intranodular. The medical history was positive for dyslipidemia, hyperglycemia, renal dysfunction, and hyperuricemia (2, 3, and 3 cases and 1 case, resp. without any parathyroid abnormality. In conclusion, thyroid HBF may be characterized by subcapsular or extranodular location, various size (usually ≥2 mm, and vascular calcifications and malformations. Features of metabolic syndrome and renal dysfunction may be present, but their exact role in the pathogenesis of HBFs remains to be elucidated.

To report the incidence of symptomatic heterotopic ossification (HO) in a defined civilian amputee population, describe its characteristics, and compare these findings to published data in military amputees. Retrospective chart analysis from July 1998 to July 2009. Ambulatory amputee clinic within a large university medical center. Adults with lower limb amputation (N=158). Not applicable. Patients with symptomatic HO confirmed by radiographs. A total of 261 patients were evaluated; 158 met inclusion criteria, with 59% having traumatic etiology, 18% vascular etiology, 22% infection, and 1% tumor. Symptomatic HO was diagnosed in 36 (22.8%) patients, and 94% patients had mild HO on radiographic scoring. Rate of HO in amputations related to trauma was not increased compared with those of other etiologies. Surgical resection of the ectopic bone was required in 4 (11%) patients. HO is seen commonly after civilian lower limb amputation regardless of etiology. The prevalence was less than that observed in previous reports from military populations. This is the first report estimating the prevalence of HO in adult civilian amputees. Copyright © 2014 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Full Text Available El presente artículo aborda la noción de imagen, como campo problemático, más allá del régimen semiológico instaurado desde los modelos lingüísticos. En general, la noción de imagen ha estado vinculada solo a la idea de “representación”, desde la cual se logró domesticar su potencial instaurador de estados de sensibilidad. Consideramos pertinente ampliar campos de reflexión sobre aspectos que no se restrinjan a su funcionalidad representacional y para ello, nos apoyaremos en el concepto de heterotopía de Michel Foucault, el cual nos servirá de ayuda, por cuanto expande el campo de reflexión estética y permite integrar a la dimensión simbólica, la función virtualizante de la imagen como productora de estados de sensibilidad. La imagen, a nuestro entender, funciona como una heterotopía, es una tipología espacio-temporal no convencional, y por tanto es estructurante y configuradora de realidad, tanto en términos sensibles como inteligibles.

A retrospective review was performed to evaluate the outcomes and complications following heterotopic ossification (HO) resection and lysis of adhesion procedures for posttraumatic contracture, after combat-related open elbow fractures. From 2004 to 2011, HO resection was performed on 30 blast-injured elbows at a mean 10 months after injury. Injuries included 8 (27%) Gustilo-Anderson type II fractures, 8 (27%) type III-A, 10 (33%) III-B, and 4 (13%) III-C. Mean preoperative flexion-extension range of motion (ROM) was 36.4°, compared with mean postoperative ROM of 83.6°. Mean gain of motion was 47.2°. Traumatic brain injury, need for flap, and nerve injury did not appear to have a significant effect on preoperative or postoperative ROM. Complications included one fracture, six recurrent contractures, and one nerve injury. The results and complications of HO resection for elbow contracture following high-energy, open injuries from blast trauma are generally comparable to those reported for HO resection following lower energy, closed injuries.

Full Text Available Protrusion of a bowel segment into another (intussusception produces severe abdominal pain and culminates in intestinal obstruction. In adults, intestinal obstruction due to intussusception is relatively rare phenomenon, as it accounts for minority of intestinal obstructions in this population demographic. Organic lesion is usually identifiable as the cause of adult intussusceptions, neoplasms account for the majority. Therefore, surgical resection without reduction is almost always necessary and is advocated as the best treatment of adult intussusception. Here, we describe a rare case of a 44-year-old male with a diffuse large B-cell lymphoma involving the terminal ileum, which had caused ileocolic intussusception and subsequently developed intestinal obstruction requiring surgical intervention. This case emphasizes the importance of recognizing intussusception as the initial presentation for bowel malignancy.

To establish stoma and stoma-free murine models of heterotopic small intestine transplantation in order to choose a more effective and reliable model. A total of 140 male 8-10 weeks age C57BL/6(B6) mice weighted 25-30 g were enrolled in the experiment. Syngeneic heterotopic small intestine transplantation was performed between C57BL/6 mice, and recipient mice were divided into either stoma or stoma-free group. Heterotopic small intestine transplantation was performed in 70 mice, with 35 mice in each group. After closing the proximal end of the graft by ligation, the distal end of graft was exteriorized as a stoma then secured to the skin of the abdominal wall in stoma group. In stoma-free group, the distal end of graft was anastomosed end-to-side to the recipient ileum. Successful rate of operation, two-week survival rate, operation time, associated complications, postoperative care time and body weight change were recorded and compared between two groups. The successful rate of stoma group was 65.7%, while it was 80.0% of stoma-free group (χ(2)=1.806, P=0.179). The operation time of donor in stoma group was (48.1±6.6) minutes, while it was (47.2±5.9) minutes in stoma-free group (t=0.598, P=0.552). The operation time of recipient in stoma group was (77.9±9.1) minutes, while it was (76.4±8.3) minutes in stoma-free group (t=0.683, P=0.497). The cold ischemic time of graft in stoma group was (34.7±4.0) minutes, while it was (33.9±4.6) minutes in stoma-free group(t=0.667, P=0.507). The two-week survival rate of stoma group was 45.7%, and it was 77.1% of stoma-free group(χ(2)=7.295, P=0.007). The stoma group had more complications[54.3%(19/35) vs. 22.9%(8/35), χ(2)=7.295, P=0.007], which needed more postoperative care time(191 min vs. 35 min). The weight loss in stoma group in the third day after operation was more significant [(81.52±5.20)% vs. (85.46±4.65)%, t=2.856, P=0.006]. By 2 weeks after operation, the weight of mice in both groups retruned to 95% of

Normalization of cortisol concentration by multikinase inhibitors have been reported in three patients with medullary thyroid cancer-related Cushing's syndrome. Aortic dissection has been reported in three patients with Cushing's syndrome. Diabetes insipidus without intrasellar metastasis, intestinal intussusception, and paraneoplastic dysautonomia have not been reported in medullary thyroid cancer. An adult male with metastatic medullary thyroid cancer presented with hyperglycemia, hypernatremia, hypokalemia, hypertension, acne-like rash, and diabetes insipidus (urine volume >8 L/d, osmolality 190 mOsm/kg). Serum cortisol, adrenocorticoitropic hormone, dehydroepiandrostenedione sulfate, and urinary free cortisol were elevated 8, 20, 4.4, and 340 folds, respectively. Pituitary imaging was normal. Computed tomography scan revealed jejunal intussusception and incidental abdominal aortic dissection. Sorafenib treatment was associated with Cushing's syndrome remission, elevated progesterone (>10 fold), normalization of dehydroepiandrostenedione sulfate, but persistently elevated cortisol concentration. Newly-developed proximal lower limb weakness and decreased salivation were associated with elevated ganglionic neuronal acetylcholine receptor (alpha-3) and borderline P/Q type calcium channel antibodies. Extreme cortisol concentration may have contributed to aortic dissection and suppressed antidiuretic hormone secretion; which combined with hypokalemia due cortisol activation of mineralocorticoid receptors, manifested as diabetes insipidus. This is the first report of paraneoplastic dysautonomia and jejunal intussusception in medullary thyroid cancer, they may be related to medullary thyroid cancer's neuroendocrine origin and metastasis, respectively. Remission of Cushing's syndrome without measurable reduction in cortisol concentration suggests a novel cortisol-independent mechanism of action or assay cross-reactivity.

Introduction: Following surgery, the formation of heterotopic ossification (HTO) can limit mobility and impair quality of life. Radiotherapy has been proven to provide efficacious prophylaxis against HTO, especially in high-risk settings. Purpose: The current review aims to determine the factors influencing HTO formation in patients receiving prophylactic radiotherapy. Methods: A systematic search of the literature was conducted on Ovid Medline, Embase and the Cochrane Central Register of Controlled Trials. Studies were included if they reported the percentage of sites developing heterotopic ossification after receiving a specified dose of prophylactic radiotherapy. Weighted linear regression analysis was conducted for continuous or categorical predictors. Results: Extracted from 61 articles, a total of 5464 treatment sites were included, spanning 85 separate study arms. Most sites were from the hip (97.7%), from United States patients (55.2%), and had radiation prescribed postoperatively (61.6%) at a dose of 700 cGy (61.0%). After adjusting for radiation site, there was no statistically significant relationship between the percentage of sites developing HTO and radiation dose (p = 0.1) or whether radiation was administered preoperatively or postoperatively (p = 0.1). Sites with previous HTO formation were more likely to develop recurrent HTO than those without previous HTO formation (p = 0.04). There was a statistically significant negative relationship between the HTO development and the cohort mean year of treatment (p = 0.007). Conclusion: Decreases in rates of HTO over time in this patient population may be a function of more efficacious surgical regimens and prophylactic radiotherapy

Full Text Available Abstract Background Jejunogastric intussusception (JGI is a rare but potentially very serious complication of gastrectomy or gastrojejunostomy. To avoid mortality early diagnosis and prompt surgical intervention is mandatory. Case presentation A young man presented with epigastric pain and bilous vomiting followed by hematemesis,10 years after vagotomy and gastrojejunostomy for a bleeding duodenal ulcer. Emergency endoscopy showed JGI and the CT scan of the abdomen was compatible with this diagnosis. At laparotomy a retrograde type II, JGI was confirmed and managed by reduction of JGI without intestinal resection. Postoperative recovery was uneventful. Conclusions JGI is a rare condition and less than 200 cases have been published since its first description in 1914. The clinical picture is almost diagnostic. Endoscopy performed by someone familiar with this rare entity is certainly diagnostic and CT-Scan of the abdomen could also help. There is no medical treatment for acute JGI and the correct treatment is surgical intervention as soon as possible.

Seegenschmiedt, Michael Heinrich; Makoski, Hans-Bruno; Micke, Oliver

2001-01-01

Purpose: Prophylactic radiotherapy (RT) can prevent ectopic bone formation about the hip after total hip arthroplasty. The German Cooperative Group on Radiotherapy for Benign Diseases conducted a patterns of care study about this indication addressing the involved institutions, RT dose concepts, clinical handling, and treatment outcome of prophylactic RT about the hip joint. Methods and Materials: In 1999, a patterns of care study was conducted in all German institutions to analyze the accrual pattern, number of patients, and different indications for the use and performance of prophylactic RT about the hip. The applied RT concepts of prophylactic RT were evaluated with regard to the RT technique, timing of RT (pre- or postoperative), RT dose prescription (median, range of single and total doses), and treatment outcome. All institutions were asked about the radiologic and functional failure rates at least 1 year after the completion of RT using the established radiologic (Brooker) and functional (Harris) scores with objective and subjective evaluation components. Results: One hundred fourteen institutions reported their clinical experience with prophylactic RT for the prevention of heterotopic ossification about the hip joint: 70 community hospitals, 23 university hospitals, and 21 private RT practices. In 1999, 5677 patients (5989 hips) had received prophylactic RT. The median number per institution was 36 patients (range 8-240). The interdisciplinary referral included orthopedic surgery (89 institutions; 3763 patients), trauma surgery (82 institutions; 1611 patients), or other disciplines (8 institutions; 298 patients). Preoperative RT was applied in 53 institutions 0.5-24 h before surgery, and postoperative RT was applied in 54 institutions 1-120 h after surgery. Most patients received 1 x 7 Gy either pre- or postoperatively. The total dose range was 5-10 Gy (preoperative RT) or 5-16 Gy (postoperative RT); the median total RT dose of both RT concepts was 7 Gy

: By using surgical mouse models, this study investigated how the tissue environment influences the osteogenic potential of muscle progenitors (m-progenitors) and potentially contributes to heterotopic ossification (HO). Injury was induced by clamping the gluteus maximus and medius (group M) or osteotomy of greater trochanter (group O) on the right hip, as well as combined muscle injury and osteotomy of greater trochanter (group M+O). The gluteus maximus and medius of the operated hips were harvested at days 1, 3, 5, and 10 for isolation of m-progenitors. The cells were cultured in an osteogenic medium for 3 weeks, and osteogenesis was evaluated by matrix mineralization and the expression of osteogenesis-related genes. The expression of type I collagen, RUNX2 (runt-related transcription factor 2), and osteocalcin by the m-progenitors of group M+O was significantly increased, compared with groups M and O. Osteogenic m-progenitors in group O increased the expression of bone morphogenetic protein 2 and also bone morphogenetic protein antagonist differential screening-selected gene aberrative in neuroblastoma. On histology, there was calcium deposition mostly in the muscles of group M+O harvested at day 10. CD56, representing myogenic progenitors, was highly expressed in the m-progenitors isolated from group M (day 10), but m-progenitors of group M+O (day 10) exhibited the highest expression of platelet-derived growth factor receptor α (PDGFR-α), a marker of muscle-derived mesenchymal stem cells (M-MSCs). The expressions of PDGFR-α and RUNX2 were colocalized in osteogenic m-progenitors. The data indicate that the tissue environment simulated in the M+O model is a favorable condition for HO formation. Most likely, M-MSCs, rather than myogenic progenitors, in the m-progenitors participate in HO formation. The prevalence of traumatic heterotopic ossification (HO) is high in war injury. The pathogenesis of HO is still unknown. This study clarified the contribution of a

Intussusception (IS) is a form of acute intestinal obstruction that occurs mainly in infants and is usually of unknown cause. An association between IS and the first licensed rotavirus vaccine, a reassortant-tetravalent, rhesus-based rotavirus vaccine (RRV-TV), led to the withdrawal of the vaccine. New rotavirus vaccines have now been developed and extensively studied for their potential association with IS. This study aimed to describe the epidemiology and to estimate the incidence of IS in Latin American infants prior to new vaccine introduction. Children under 2 years of age representing potential IS cases were enrolled in 16 centers in 11 Latin American countries from January 2003 to May 2005. IS cases were classified as definite, probable, possible or suspected as stated on the Brighton Collaboration Working Group guidelines. From 517 potential cases identified, 476 (92%) cases were classified as definite, 21 probable, 10 possible and 10 suspected for intussusception. Among the 476 definite IS cases, the median age at presentation was 6.4 months with 89% of cases aged days with a high prevalence of surgery as the primary treatment (65%). Most cases (88%) made a complete recovery, but 13 (3%) died. No clear seasonal pattern of IS cases emerged. This study describes the epidemiology and estimates the incidence of IS in Latin American infants prior to the introduction of new rotavirus vaccines. The incidence of IS was found to vary between different countries, as observed in previous studies. Clinical study identifier 999910/204 (SERO-EPI-IS-204).

AIM: The purpose of this study was to assess screening times and resulting dose implication at pneumatic reduction of intussusception in the paediatric age group and to examine the relationship with the outcome of the procedure. MATERIALS AND METHODS: We retrospectively reviewed the case notes and departmental records of 143 children who had undergone a total of 153 pneumatic reductions in our department over a 4-year period. Success rates, screening times and available dose-area products (DAP) were recorded. The DAPs were converted to effective dose (ED) for 77 procedures. RESULTS: A 76.5% (117/153) success rate was achieved with a recurrence rate of 6.5% and only one complication: a perforation. Screening times were recorded in 137 reductions and ranged from 15 s to 22.6 min. Although the longest screening time was associated with an unsuccessful outcome, the second longest time of 21 min was successful. This gave a DAP of 1278 cGy cm 2 and an ED of 12.73 mSv, which is equivalent to approximately 400 abdominal films for a 1-year-old. A lifetime risk of fatal cancer of one in 1000 was achieved, assuming the worst case, after a screening time of 30 min on our conventional fluoroscopy unit. CONCLUSION: Our success rate compares well with other centres. Our institution is a tertiary referral centre and the occasional long screening time may reflect the delay and complex nature of the patients referred. Persistence at air reduction may be successful and the success rate increases with delayed attempts but the risks of the increasing radiation burden must be weighed against the risks of emergency surgery and anaesthesia.

Clinically applicable immunosuppressive regimens (IS) were investigated first, then treatments known to be effective in hypersensitized patients or those with recalcitrant rejection reactions. Consecutive experiments were carried out between 2009 and 2013. Twenty-one genetically modified pigs (GGTA1-knockout/hCD46/± thrombomodulin, in one case HLA-E instead) were used as donors. In all experiments, two cycles of immunoabsorption reduced preformed antibodies. Recipient baboons were divided into two groups according to IS regimen: In group one (n = 10), pre-treatment started either one (anti-CD20) or four weeks (anti-CD20 plus the proteasome inhibitor bortezomib) prior to transplantation. The extended conventional (as for allotransplantation) immunosuppressive maintenance regimen included anti-thymocyte globuline, tacrolimus, mycophenolate mofetil, methylprednisolone and weekly anti-CD20. In group two (n = 11), myeloablative pre-treatment as in multiple myeloma patients (long and short regimens) was added to extended conventional IS; postoperative total thoracic and abdominal lymphoid irradiation (TLI; single dose of 600 cGY) was used to further reduce antibody-producing cells. In the perioperative course, the surgical technique was safely applied: 19 baboons were weaned off extracorporeal circulation and 17 extubated. Nine animals were lost in the early postoperative course due to causes unrelated to surgical technique or IS regimen. Excluding these early failures, median graft survival times of group 1 and 2 were 18.5 (12-50) days and 16 (7-35) days. Necropsy examination of group 1 donor organs revealed hypertrophy of the left ventricular wall in the six longer-lasting grafts; myocardial histology confirmed pre

Heterotopic gastric mucosa (HGM) of the esophagus is a congenital anomaly consisting of ectopic gastric mucosa. It may be connected with disorders of the upper gastrointestinal tract, exacerbated by Helicobacter pylori. The diagnosis of HGM is confirmed via endoscopy with biopsy. Histopathology provides the definitive diagnosis by demonstrating gastric mucosa adjacent to normal esophageal mucosa. HGM located in the distal esophagus needs differentiation from Barrett's esophagus. Barrett's esophagus is a well-known premalignant injury for adenocarcinoma of the esophagus. Malignant progression of HGM occurs in a stepwise pattern, following the metaplasia-dysplasia-adenocarcinoma sequence.We present a rare case of a teenage girl with HGM located in the distal esophagus, associated with chronic gastritis and biliary duodenogastric reflux. Endoscopy combined with biopsies is a mandatory method in clinical evaluation of metaplastic and nonmetaplastic changes within HGM of the esophagus.

Formation of heterotopic bone (HTB) following total hip replacement may partially or completely ankylose the joint space, causing pain and/or limiting the range of motion. Patients at high risk for formation of HTB postoperatively include those with previous HTB formation, heterotopic osteoarthritis, and active rheumatoid spondylitis. Patients in these high risk groups have a 63-69% incidence of post-operative HTB formation, usually seen radiographically by 2 months post-operation. From 1980-1986 twenty-nine hips in 28 consecutively treated patients were irradiated post-operatively at the UCLA Center for the Health Sciences. The indication for irradiation was documented HTB formation previously in 26 of the 27 hips presented below. From 1980-1982 patients received 20 Gray (Gy) in 2 Gy fractions; from 1982-1986 the dose was reduced to 10 Gy in 2 Gy fractions. Twenty-seven hips in 26 patients completed therapy and were available for evaluation, with a minimum of 2 month follow-up, and a median follow-up of 12 months. Three of 27 hips developed significant HTB (Brooker grade III or IV) post-operatively, whereas 5 of 27 hips developed minor, nonsymptomatic HTB (Brooker grade I). When irradiation was begun by postoperative day 4, 0 of 17 hips formed significant HTB. If irradiation began after post-operative day 4, 3 of 10 hips formed significant HTB (Brooker grade III or IV). These 3 hips received doses of 10 Gy in one hip and 20 Gy in the other 2 hips. There were no differences in the incidence or severity of side effects in the 10 Gy vs. the 20 Gy treatment groups. Eighteen hips received 10 Gy, 8 hips 20 Gy and, 1 hip 12 Gy. In conclusion, 10 Gy in 5 fractions appears as effective as 20 Gy in 10 fractions at preventing post-operative formation of HTB. For optimal results, treatment should begin as early as possible prior to post-operative day 4

To present an animal model to assess the effects of end-to-side innervation in the heterotopically transplanted model with reduced chances of neural contamination. The medial portion of the gastrocnemius muscle in wistar male rats was isolated and its pedicle dissected and performed a flap in the abdominal portion. To prevent neural contamination in the abdominal region, the muscle was wrapped with a Goretex(r) sheet. The specimens were divided into 2 groups (G). In G1 was performed an end-to-end suture between tibial nerve of the gastrocnemius and femoral motor nerve and between the saphenous sensory nerve and the motor nerve. In G2 was performed a end-to-side suture between the tibial nerve and the motor femoral and between the tibial nerve and saphenous motor nerve. The specimens were evaluated 60 days later to check the structure of the neurorraphy. Sections were obtained proximal and distal to the coaptation site. The medial gastrocnemius muscle had the advantage of maintaining visible mass after 60 days. No disruption of the coaptation site was found. No major injury to the donor nerve was seen in group 2. The proposed model is simple, reproduciple and prevent the neural contamination in the flap in end-to-side suture.

Full Text Available Failure of obliteration of vitellointestinal duct (VID can present with a wide variety of congenital intestinal malformations. Patient can present with the anomaly itself or due to complications secondary to the anomaly like intestinal obstruction due to volvulus, intussusception or adhesions. Prolapsed ilial loops through a patent VID is a rare presentation of the above. To date only fourteen cases of this presentation have been reported in the English medical literature. We are reporting a case of the same in a new-born presenting with it from the time of birth, which to the best of our knowledge has not been reported before and therefore this the youngest reported case of its nature in the current English medical literature.

Heterotopic ossification (HO) develops in a majority of combat-related amputations wherein early bacterial colonization has been considered a potential early risk factor. Our group has recently developed a small animal model of trauma-induced HO that incorporates many of the multifaceted injury patterns of combat trauma in the absence of bacterial contamination and subsequent wound colonization. We sought to determine if (1) the presence of bioburden (Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus [MRSA]) increases the magnitude of ectopic bone formation in traumatized muscle after amputation; and (2) what persistent effects bacterial contamination has on late microbial flora within the amputation site. Using a blast-related HO model, we exposed 48 rats to blast overpressure, femur fracture, crush injury, and subsequent immediate transfemoral amputation through the zone of injury. Control injured rats (n = 8) were inoculated beneath the myodesis with phosphate-buffered saline not containing bacteria (vehicle) and treatment rats were inoculated with 1 × 10(6) colony-forming units of A baumannii (n = 20) or MRSA (n = 20). All animals formed HO. Heterotopic ossification was determined by quantitative volumetric measurements of ectopic bone at 12-weeks postinjury using micro-CT and qualitative histomorphometry for assessment of new bone formation in the residual limb. Bone marrow and muscle tissue biopsies were collected from the residual limb at 12 weeks to quantitatively measure the bioburden load and to qualitatively determine the species-level identification of the bacterial flora. At 12 weeks, we observed a greater volume of HO in rats infected with MRSA (68.9 ± 8.6 mm(3); 95% confidence interval [CI], 50.52-85.55) when compared with A baumannii (20.9 ± 3.7 mm(3); 95% CI, 13.61-28.14; p infection but were positive for other strains of bacteria (1.33 × 10(2) ± 0.89 × 10(2); 95% CI, -0.42 × 10(2)-3.08 × 10(2) and 1.25 × 10(6) ± 0

Heterotopic salivary gland tissue (HSGT) in the lower neck is an unusual developmental anomaly with characteristic clinical and microscopic findings. The exact embryogenesis remains unclear. This rare entity must be considered in the differential diagnosis of neck mass with fistula. We present a typical HSGT totally removed using the stepladder excision technique and showing an internal fistula. Interpretation of this case from the anatomical and pathological points of view, we support the argument that the embryogenesis of HSGT is more probably related to ectodermal heteroplasia of the precervical sinus of His and further conclude that an association with branchial cleft sinus may exist and cannot be seen as an exclusion criteria for diagnosis of HSGT. Due to possible but infrequent neoplastic transformation, it is important to check HSGT in every encountered cervical anomaly related to any branchial apparatus derived lesion.

To retrospectively evaluate the CT findings and clinicopathologic features in patients with gastrointestinal (GI) involvement of recurrent renal cell carcinoma (RCC). The medical records were reviewed for 15 patients with 19 pathologically proven GI tract metastases of RCC. The CT findings were analyzed to determine the involved sites and type of involvement; lesion size, morphology, and contrast enhancement pattern; and occurrence of lymphadenopathy, ascites and other complications. The most common presentation was GI bleeding (66.7%). The average interval between nephrectomy and the detection of GI involvement was 30.4 ± 37.4 months. GI lesions were most commonly found in the ileum (36.8%) and duodenum (31.6%). A distant metastasis (80%) was more common than a direct invasion from metastatic lesions. The mean lesion size was 34.1 ± 15.0 mm. Intraluminal polypoid masses (63.2%) with hyperenhancement (78.9%) and heterogeneous enhancement (63.2%) were the most common findings. No patients had regional lymphadenopathy. Complications occurred in four patients, with one each of bowel obstruction, intussusception, bile duct dilatation, and pancreatic duct dilatation. GI involvement of recurrent RCC could be included in the differential diagnosis of patients with heterogeneous, hyperenhanced intraluminal polypoid masses in the small bowel on CT scans along with a relative paucity of lymphadenopathy.

Twenty patients who had undergone a heterotopic heart transplant were studied prospectively to determine the relationship between rejection and ventricular dysfunction assessed from gated blood pool studies. A fully automated method for detecting ventricular edges was implemented; its success rate for the grafted left and right ventricles was 94% and 77%, respectively. The parameters, peak ejection and filling rates, were calculated pixel per pixel using a two-harmonic Fourier algorithm and then averaged over the ventricular region of interest. Peak filling and ejection rates were closely related with the severity of the rejection, while the left ventricular ejection fraction was not. Peak filling rates of both ventricles were the indices closely related to the presence of moderate rejection. Despite the low number of patients, these data suggested that gated blood pool derived indices of ventricular function are associated with ventricular dysfunction resulting from myocarditis rejection. Radionuclide ventriculography provides parametric data which are accurate and reliable for the diagnosis of rejection. (orig.)

Respiratory distress associated with heterotopic gastrointestinal cysts of the oral cavity: A case report

Full Text Available Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development. The majority of these lesions occur in the anterior ventral surface of the tongue and extend to the floor of the mouth. They are confused clinically by surgeons in cases of head and neck masses in children as ranulas, dermoid and thyroglossal cysts, and lymphangioma. We report the case of a 28-day newborn with a 3.6 cm oval mass on the floor of the mouth causing difficulty eating and cyanosis during crying. Complete surgical excision was performed by an oral approach under general anesthesia. Microscopic examination revealed gastric epithelium with tall columnar mucous cells on the surface and numerous short closed crypts, resembling fundal glands and mature gastric epithelium.

Heterotopic ossification (HO) is the formation of mature, lamellar bone within soft tissues other than the periosteum. There are three recognized etiologies of HO: traumatic, neurogenic, and genetic. Presently, there are no definitively documented causal factors of HO. The following factors are presumed to place a patient at higher risk: 60 years of age or older, male, previous HO, hypertrophic osteoarthritis, ankylosing spondylitis, diffuse idiopathic skeletal hyperostosis, prior hip surgery, and surgical risk factors. A 33-year-old male, involved in a motor vehicle crash, sustained an irreducible acetabulum fracture/dislocation, displaced proximal humerus fracture, and an impacted pilon fracture. During the time of injury, he was intoxicated from inhaling the aerosol propellant used in "dust spray" cans (1,1-difluoroethane, C2H4F2). Radiographs identified rapid pathologic bone formation about the proximal humeral metaphysis, proximal femur, elbow, and soft tissue several months following the initial injury. The patient did not have any genetic disorders that could have attributed to the bone formation but had some risk factors (male, fracture with dislocation). Surgically, the recommended precautions were followed to decrease the chance of HO. Although the patient did not have neurogenic injuries, the difluoroethane in dusting spray can cause damage to the central nervous system. Signals may have been mixed causing the patient's body to produce bone instead of tissue to strengthen the injured area. What is unusual in this case is the rate at which the pathological bone formation appeared, which was long outside the 4-6 week window in which HO starts to appear. The authors are not certain as to the cause of this rapid formation but suspect that the patient's continued abuse of inhaled aerosol propellants may be the culprit.

Heterotopic ossification (HO) around shoulder arthroplasty is a frequent finding with unclear clinical relevance. This study evaluated the incidence, relevance, and predisposing factors of HO in the long head of the triceps tendon after reverse shoulder arthroplasty. Retrospective chart review was conducted to identify patients who had a reverse shoulder arthroplasty performed between 2008 and 2012. Patient demographics, implant types, and diagnoses were noted. Three fellowship-trained shoulder/elbow surgeons independently evaluated postoperative Grashey radiographs using a novel classification system. Within a 164-patient cohort, the overall HO rate in the long head of the triceps tendon was 61.6%; 23.2% of osteophytes were considered impinging, 14.6% had notching, 14.0% were free-floating, and 3.0% appeared ankylosed. Although not statistically significant, revision surgery had a higher rate of HO (68.3%) compared with primary surgery (59.4%). There was no difference in HO rates between diagnoses or implant types. Male and female HO rates were 74.0% and 56.1%, respectively (P = .0304). Between patients with and without HO, forward elevation was 121° compared with 133° (P = .0087) and external rotation was 19° compared with 25° (P = .0266); however, HO size did not significantly affect motion. Using our novel classification scheme, HO was a common finding in this series. Men had a higher rate of HO formation, and HO formation was associated with worse postoperative motion. Further study is needed to fully characterize the clinical implications of HO involving the long head of the triceps tendon and to explore potential preventive measures.

Fibrocytes are integral in the development of fibroproliferative disease after lung transplantation. Undifferentiated fibrocytes (CD45+anti-collagen 1+CXCR4+) preferentially traffic by way of the CXCR4/CXCL12 axis and differentiate into smooth muscle actin-producing (CD45+CXCR4+α-smooth muscle actin+) cells. We postulated that an antibody directed against CXCL12 would attenuate fibrocyte migration and fibro-obliteration of heterotopic tracheal transplant allografts. A total alloantigenic mismatch murine heterotopic tracheal transplant model of obliterative bronchiolitis was used. The mice were treated with either goat-anti-human CXCL12 F(ab')(2) or goat IgG F(ab')(2). Buffy coat, bone marrow, and trachea allografts were collected and analyzed using flow cytometry. Tracheal luminal obliteration was assessed using hematoxylin-eosin and Direct Red 80 collagen stain. Compared with the controls, the anti-CXCL12-treated mice showed a significant decrease in tracheal allograft fibrocyte populations at 7 and 21 days after transplantation. Bone marrow and buffy coat aspirates showed the same trend at 7 days. In the anti-CXCL12-treated mice, there was a 35% decrease in luminal obliteration at 21 days (65% vs 100% obliterated; interquartile range, 38% vs 10%; P = .010) and decreased luminal collagen deposition at 21 and 28 days after transplantation (P = .042 and P = .012, respectively). Understanding the role of fibrocytes in airway fibrosis after lung transplantation could lead to a paradigm shift in treatment strategy. Anti-CXCL12 antibody afforded protection against infiltrating fibrocytes and reduced the deterioration of the tracheal allografts. Thus, the CXCR4/CXCL12 axis is a novel target for the treatment of fibro-obliteration after lung transplantation, and the quantification of fibrocyte populations could provide clinicians with a biomarker of fibrosis, allowing individualized drug therapy.

Traumatic heterotopic ossification (HO) is the pathological formation of bone in soft tissue and is a debilitating sequela following acute trauma involving blast-related extremity musculoskeletal injuries, severe burns, spinal cord injury, and traumatic brain injury. Over 60% of combat related injuries and severe burns develop HO; often resulting in reduced mobility, chronic pain, ulceration, tissue entrapment, and reduced ambulation. Detection and prognosis is limited by current clinical imaging modalities (computed tomography, radiography, and ultrasound). This study identifies Raman spectral signatures corresponding to histological changes in a combat-trauma induced rat HO model at early time points prior to radiographic evidence of HO. HO was induced in Sprague-Dawley rats via blast over pressure injury, mid-femoral fracture, soft tissue crush injury, and limb amputation through the zone of injury. Rats were euthanized, and amputated limbs were formalin fixed and embedded in paraffin; 10 μm sections were placed on gold slides, and paraffin was chemically removed. Tissues from sham-treated animals served as controls. Tissue maps consisting of Raman spectra were generated using a Raman microprobe system with an 80-90 μm spot size and 785 nm excitation in regions exhibiting histological evidence of early HO development according to adjacent HE sections. Factors were extracted from mapping data using Band-Target Entropy Minimization algorithms. Areas of early HO were highlighted by a Raman factor indicative of the presence of collagen. Identification of collagen as an early marker of HO prior to radiographic detection in a clinically relevant animal model serves to inform future clinical work.

Purpose: To analyze the impact of different body mass index (BMI) as a surrogate marker for heterotopic ossification (HO) in patients who underwent surgical repair (SR) for displaced acetabular fractures (DAF) followed by radiation therapy (RT). Methods and Materials: This is a single-institution retrospective study of 395 patients. All patients underwent SR for DAF followed by RT ± indomethacin. All patients received postoperative RT, 7 Gy, within 72 h. The patients were separated into four groups based on their BMI: 30. The end point of this study was to evaluate the efficacy of RT ± indomethacin in preventing HO in patients with different BMI. Results: Analysis of BMI showed an increasing incidence of HO with increasing BMI: 30 (31%), 51 of 167. Chi-square and multivariate logistic regression analysis showed that the correlation between odds of HO and BMI is significant, p < 0.0001. As the BMI increased, the risk of HO and Brooker Classes 3, 4 HO increased. The risk of developing HO is 1.0× (10%) more likely among those with higher BMI compared with those with lower BMI. For a one-unit increase in BMI the log odds of HO increases by 1.0, 95% CI (1.06–1.14). Chi-square test shows no significant difference among all other factors and HO (e.g., indomethacin, race, gender). Conclusions: Despite similar surgical treatment and prophylactic measures (RT ± indomethacin), the risk of HO appears to significantly increase in patients with higher BMI after DAF. Higher single-fraction doses or multiple fractions and/or combination therapy with nonsteroidal inflammatory drugs may be of greater benefit to these patients.

Defining the roles of heterotopic and normotopic cortex in the epileptogenic networks in patients with nodular heterotopia is challenging. To elucidate this issue, we compared heterotopic and normotopic cortex using quantitative signal analysis on stereoelectroencephalography (SEEG) recordings. Clinically relevant biomarkers of epileptogenicity during ictal (epileptogenicity index; EI) and interictal recordings (high-frequency oscillation and spike) were evaluated in 19 patients undergoing SEEG. These biomarkers were then compared between heterotopic cortex and neocortical regions. Seizures were classified as normotopic, heterotopic, or normoheterotopic according to respective values of quantitative analysis (EI ≥0.3). A total of 1,246 contacts were analyzed: 259 in heterotopic tissue (heterotopic cortex), 873 in neocortex in the same lobe of the lesion (local neocortex), and 114 in neocortex distant from the lesion (distant neocortex). No significant difference in EI values, high-frequency oscillations, and spike rate was found comparing local neocortex and heterotopic cortex at a patient level, but local neocortex appears more epileptogenic (p < 0.001) than heterotopic cortex analyzing EI values at a seizure level. According to EI values, seizures were mostly normotopic (48.5%) or normoheterotopic (45.5%); only 6% were purely heterotopic. A good long-term treatment response was obtained in only two patients after thermocoagulation and surgical disconnection. This is the first quantitative SEEG study providing insight into the mechanisms generating seizures in nodular heterotopia. We demonstrate that both the heterotopic lesion and particularly the normotopic cortex are involved in the epileptogenic network. This could open new perspectives on multitarget treatments, other than resective surgery, aimed at modifying the epileptic network.

Appendiceal intussusception is a very rare pathological condition, an incidence, as revealed by appendectomy specimens, of only 0.01 percent. There are various types among which complete invagination of the appendix is very rare. We encountered a case of intussusception of the appendix with complete invagination induced by appendiceal adenocarcinoma. A preoperative diagnosis of appendiceal adenocarcinoma and intussusception was not possible, but a final pathological report confirmed these conditions and retrospective analysis of a barium enema showed a finger-like filling defect of the cecum, a relatively specific finding in such cases. We describe a case involving a 39-year old man who one month earlier had noted the onset of pain in the right lower abdomen. (author)

We encountered a case of intussusception of the appendix with complete invagination induced by appendiceal adenocarcinoma. A preoperative diagnosis of appendiceal adenocarcinoma and intussusception was not possible, but a final pathological report confirmed these conditions and retrospective analysis of a barium enema showed a finger-like filling defect of the cecum, a relatively specific finding in such cases. We describe a case involving a 39-year old man who one month earlier had noted the onset of pain in the right lower abdomen. (author)

E-mail: vivianmedvet@yahoo.com.br It is described a case of dentigerous cyst in a 2-year-old female pampa horse that showed swelling in the right temporal region and a draining tract near the right pinna. The diagnosis is established with clinical, radiographic and histopathological examination of the surrounding structures. Dentigerous cyst is an uncommon condition in horses and it occurs most frequently in young animals. Twelve 1,3-4 cm white firm structures were removed, some with central pulp canal and longitudinal grooves in the external surface, grossly resembling teeth. Microscopic examination showed a structure compatible with dental tissue lined by a non-keratinezed epithelium. A lympho-plasmocitary inflammatory reaction was also seem in the dermis. Differential diagnoses includes congenital deformities of the bone, trauma, abscess and perforating foreign bodies. Post- -operative complications include haemorrhage, fracture of the temporal bone and permanent neurological damage. This case highlights the importance of the investigation of recurrent abscess in horses that are resistant to antibiotics.

Gastric carcinoma is derived from epithelial cells in the gastric mucosa. We reported an extremely rare case of submucosal gastric carcinoma originating from the heterotopic submucosal gastric gland (HSG) that was safely diagnosed by laparoscopy and endoscopy cooperative surgery (LECS). A 66-year-old man underwent gastrointestinal endoscopy, which detected a submucosal tumor (SMT) of 1.5 cm in diameter on the lesser-anterior wall of the upper gastric body. The tumor could not be diagnosed histologically, even by endoscopic ultrasound-guided fine-needle aspiration biopsy. Local resection by LECS was performed to confirm a diagnosis. Pathologically, the tumor was an intra-submucosal well differentiated adenocarcinoma invading 5000 μm into the submucosal layer. The resected tumor had negative lateral and vertical margins. Based on the Japanese treatment guidelines, additional laparoscopic proximal gastrectomy was curatively performed. LECS is a less invasive and safer approach for the diagnosis of SMT, even in submucosal gastric carcinoma originating from the HSG. PMID:26306144

Purpose: To analyze the impact of different body mass index (BMI) as a surrogate marker for heterotopic ossification (HO) in patients who underwent surgical repair (SR) for displaced acetabular fractures (DAF) followed by radiation therapy (RT). Methods and Materials: This is a single-institution retrospective study of 395 patients. All patients underwent SR for DAF followed by RT {+-} indomethacin. All patients received postoperative RT, 7 Gy, within 72 h. The patients were separated into four groups based on their BMI: <18.5, 18.5-24.9, 25-29.9, and >30. The end point of this study was to evaluate the efficacy of RT {+-} indomethacin in preventing HO in patients with different BMI. Results: Analysis of BMI showed an increasing incidence of HO with increasing BMI: <18.5, (0%) 0/6 patients; 18.5-24.9 (6%), 6 of 105 patients developed HO; 25-29.9 (19%), 22 of 117; >30 (31%), 51 of 167. Chi-square and multivariate logistic regression analysis showed that the correlation between odds of HO and BMI is significant, p < 0.0001. As the BMI increased, the risk of HO and Brooker Classes 3, 4 HO increased. The risk of developing HO is 1.0 Multiplication-Sign (10%) more likely among those with higher BMI compared with those with lower BMI. For a one-unit increase in BMI the log odds of HO increases by 1.0, 95% CI (1.06-1.14). Chi-square test shows no significant difference among all other factors and HO (e.g., indomethacin, race, gender). Conclusions: Despite similar surgical treatment and prophylactic measures (RT {+-} indomethacin), the risk of HO appears to significantly increase in patients with higher BMI after DAF. Higher single-fraction doses or multiple fractions and/or combination therapy with nonsteroidal inflammatory drugs may be of greater benefit to these patients.

Full Text Available Aims: to analyze diagnostic and therapeutic options depending on the clinical symptoms, location, and lesions associated with intussusception, together with their follow-up and complications. Patients and methods: patients admitted to the Morales Meseguer General University Hospital (Murcia between January 1995 and January 2009, and diagnosed with intestinal invagination. Data related to demographic and clinical features, complementary explorations, presumptive diagnosis, treatment, follow-up, and complications were collected. Results: there were 14 patients (7 males and 7 females; mean age: 41.9 years-range: 17-77 who presented with abdominal pain. The most reliable diagnostic technique was computed tomography (8 diagnoses from 10 CT scans. A preoperative diagnosis was established in 12 cases. Invaginations were ileocolic in 8 cases (the most common, enteric in 5, and colocolic in 2 (coexistence of 2 lesions in one patient. The etiology of these intussusceptions was idiopathic or secondary to a lesion acting as the lead point for invagination. Depending on the nature of this lead point, the cause of the enteric intussusceptions was benign in 3 cases and malignant in 2. Ileocolic invaginations were divided equally (4 benign and 4 malignant, and colocolic lesions were benign (2 cases. Conservative treatment was implemented for 4 patients and surgery for 10 (7 in emergency. Five right hemicolectomies, 3 small-bowel resections, 2 left hemicolectomies, and 1 ileocecal resection were performed. Surgical complications: 3 minor and 1 major (with malignant etiology and subsequent death. The lesion disappeared after 3 days to 6 weeks in patients with conservative management. Mean follow-up was 28.25 months (range: 5-72 months. Conclusions: a suitable imaging technique, preferably CT, is important for the diagnosis of intussusception. Surgery is usually necessary but we favor conservative treatment in selected cases.Objetivos: analizar las opciones terap

Full Text Available Resumen Este artículo identifica algunas de las formas de organización del género y la sexualidad en el espacio sociopolítico colombiano. Haciendo uso de lo que se podría llamar un juego de escalas, que va de lo global a lo local y viceversa, se hace referencia al cuestionamiento del que es objeto actualmente el enfoque de género, en uno de los períodos más densos de la historia colombiana reciente. Para tal objeto, se exploran tres formas de relación de los actores con las políticas de género y sexualidad: las intersecciones e interfaces que se producen entre las lógicas e intereses del dogmatismo religioso y los sectores sociales conservadores, en oposición a quienes defienden la democratización de la sociedad; las periferias que dan cuenta de las áreas y actores sociales que se dejan por fuera del núcleo de la política sexual; y las heterotopías, esos lugares otros que constituyen, así sea de forma transitoria, impugnaciones del ordenamiento social y sexual.

Full Text Available Peutz-Jeghers syndrome is a rare hereditary autosomal dominant disease caused by a mutation of the tumor suppressor gene serine/threonine kinase 11 located in chromosome 19p13.3. It is characterized by the presence of extensive mucocutaneous pigmentation, especially of the lips and the occurrence of hamartomatous polyps throughout the gastrointestinal tract. Gastrointestinal hamartomas occur predominantly in the small intestine and can become symptomatic leading usually to intestinal obstruction and abdominal pain. We present a case of recurrent intestinal obstruction caused by small bowel intussusception treated by reduction, enterotomy and polypectomy and followed by intraoperative enteroscopy and endoscopic polypectomy.

Full Text Available Heterotopic ossification (HO is the ectopic development of normal bone within soft tissue that can occur after traumatic injury. It is uncommon and may be missed or misdiagnosed, which can lead to complications. We report the case of an 84-year-old male with a previous history of a laparotomy who underwent resection of an intra-abdominal tumor through a midline incision. On postoperative day six, the patient was taken to the operating room, as succus was draining from the incision. Upon re-exploration, sharp bone-like material was found in the wound directly adjacent to an enterotomy. Pathology confirmed mature lamellar bone and the diagnosis of HO. This is the first report of postoperative intestinal perforation secondary to HO in a midline wound. We report this case to encourage accurate reporting of HO and its morbidity and complications for the benefit of appropriate surgical planning and epidemiologic tracking of outcomes.

Full Text Available CONTEXT: The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy. OBJECTIVES: To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome. METHODS: Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III. In addition, sphincter damage was evaluated. Patients were grouped according to age (50y and stratified by mode of delivery and parity: group I (50y: 251 patients, 60 nulliparous, 148 vaginal delivery and 43 only caesarean section. Additionally, patients were stratified by number of vaginal deliveries: 0 - nulliparous (n = 135, 1 - vaginal (n = 46, >1 - vaginal (n = 166. RESULTS: Rectocele grade II or III, intussusception, rectocele + intussusception and sphincter damage were more prevalent in Group II (P = 0.0432; P = 0.0028; P = 0.0178; P = 0.0001. The stratified groups (nulliparous, vaginal delivery and cesarean did not differ significantly with regard to rectocele, intussusception or anismus in each age group. Entero/sigmoidocele was more prevalent in the vaginal group 50y. No correlation was found between rectocele and the number of vaginal deliveries. CONCLUSION: Higher age (>50 years was shown to influence the prevalence of significant rectocele, intussusception and sphincter damage in women. However, delivery mode and parity were not correlated with the prevalence of rectocele, intussusception and anismus in women with obstructed defecation.

Retrograde gastroesophageal intussusception after peroral endoscopic myotomy in a patient with achalasia cardia: A case report.

Retrograde gastroesophageal intussusception (RGEI) is a relatively rare gastrointestinal (GI) disorder in which a portion of the stomach wall invaginates into the esophagus. More recently, peroral endoscopic myotomy (POEM) has emerged as an endoscopic alternative to surgical myotomy for achalasia, and, to the best of our knowledge, our case is the first RGEI after POEM to be reported. A 22-year-old male was presented with a history of vomiting, intractable retching and hematemesis for 3 days. He had a history of achalasia and underwent POEM 3 years ago caused by symptoms of severe dysphagia to solid and liquid. Initially, the patient was diagnosed with a blood-filled esophagus, and the mid esophagus was occluded with a ball-like mass, however, the final diagnosis of RGEI was made by thoracotomy. A therapeutic strategy of conservative treatment and left transthoracic surgery were applied. The surgery and post operative course were uneventful, and he remained asymptomatic 1 year after operation. POEM is a reliable and minimally invasive endoscopic method for esophageal achalasia. Early recognition and severity of RGEI are essential to decrease the unwanted complications. Upper GI series, esophagogastroduodenoscopy and computed tomography scan are helpful for diagnostic purposes of RGEI. Conservative treatment, endoscopic intervention, and surgery are the mainstay of treatments for RGEI. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

Purpose: Heterotopic ossification (HO) about the elbow has been described after surgery, trauma, and burns. Even limited deposits can lead to significant functional deficits. Little data exist regarding outcomes of patients treated with radiation therapy (RT) after elbow surgery. We report here the Cleveland Clinic experience with single-fraction radiation following surgery to the elbow. The primary endpoint was the rate of new HO after RT. Secondary endpoints were range of motion, functional compromise, and toxicity. Methods and Materials: From May 1993 to July 2006, 36 patients underwent elbow surgery followed by single-fraction RT. Range of motion data were collected before and during surgery and at last follow-up. Radiographs were reviewed for persistent or new HO. Patient and treatment factors were analyzed for correlation with development of HO or functional compromise. Results: Median follow-up was 8.7 months, median age was 42 years, and 75% of patients were male. Twenty-six (72%) patients had HO prior to surgery. All patients had significant limitations in flexion/extension or pronation/supination at baseline. Thirty-one (86%) patients had prior elbow trauma, and 26 (72%) patients had prior surgery. RT was administered a median of 1 day postoperatively (range, 1-4 days). Thirty-four patients received 700 cGy, and 2 patients received 600 cGy. Three (8%) patients developed new HO after RT. All patients had improvement in range of motion from baseline. No patient or treatment factors were significantly associated with the development of HO or functional compromise. Conclusions: Single-fraction RT after surgery to the elbow is associated with favorable functional and radiographic outcomes.

Esophagus adenocarcinomas developing within heterotopic gastric mucosa are very rare and described to be found endoscopically in a prevalence of .29%. We report a case of cervical adenocarcinoma arising in ectopic gastric mucosa in a fifty-four year old man. The patient underwent a mucosal resection followed with exclusive chemoradiotherapy because of infiltration of the sub mucosa layer. A radiotherapy dose of 60 Gy ( 2 Gy/Fr, 30 Fr) was realized with a reduction of the fields at 50 Gy associated with a continuous 5FU-cisplatin combination after eliminating known mutation in the dihydro-pyrimidine of the dehydrogenase gene. for this tumor, surgery is the main treatment, (oesophagectomy associated with laryngo-pharyngectomy) and has an important repercussion on the quality of life. Because of the refusal of our patient, after a mucosal resection attempt, we proposed our patient a chemoradiotherapy. For the first time in the literature, we report the results of radio chemotherapy for this rare tumor. Eighteen months after the treatment, the patient is alive without sign of recurrence. The radio chemotherapy could be a safety treatment for this rare tumor associated with a good quality of life. A review of the literature since 1950 will be shown. (authors)

Objective: To evaluate the usefulness of CT and US in the diagnosis of gastrointestinal involvement in children with rheumatoid purpura. Methods: Abdominal CT and US findings in 14 cases of clinical and laboratory confirmed of rheumatoid purpura were analyzed. There were 9 males and 5 females with the age ranged from 6 months to 14 years. All patients was hospitalized because of acute abdominal emergency, and the clinical presentations included paroxysm of abdomen pain, vomiting, without skin rashes and subcutaneous hemorrhage. CT examination was done in 7 cases, and contrast enhancement was performed in 1 case. Abdominal ultrasound was done in 9 cases. Both CT and US were done in 2 cases. Results: All patients demonstrated multiple or single areas of bowel-wall thickening, localized intraluminal narrowing, mesenteric edema, and liquid in abdominal cavity by CT and ultrasound. Conclusion: Abdominal CT and US examination have important values in differential diagnosis of acute abdominal disorders in children patients with rheumatoid purpura. Before appearing skin rashes, classical picture can help for the diagnosis and clinical treatment. Abdominal CT and US examination can also find the intussusception, bowel obstruction, and perforation in rheumatoid purpura

There are many method of treatment of the intussusception in children, including surgery, barium reduction, air reduction, and saline enema under ultrasonographic monitoring. Among them, barium reduction and air reduction have been used widely as nonsurgical method of treatment in radiologic department. During barium reduction, the bottle filled with barium solution must not be elevated over a 3 feet from the operating table. In air reduction, diagnostic pressure is about 60 mmHg and pressure during reduction usually is maintained between 90 mmHg and 130 mmHg. The authors have studied about pressure difference of barium solution by changing height of the bottle filled with barium solution, and have compared with pressure in air reduction. The results are as follows; 1. Pressure of 20 w/v % barium solution at the 60 cm height is 44.4 mmHg, and 69.6 mmHg at the 90 cm height. 2. Pressure of 40 w/v % barium solution at the 60 cm height is 51.4 mmHg, and 80.1 mmHg at the 90 cm height. 3. Pressure of 40 w/v % barium solution at the 90cm height is much lower than the pressure maintained during air reduction, and this difference in pressure may be one of the causes of low reduction rate in barium reduction then air reduction. 4. The pressure gradient per 10 cm height is about 8.45 mmHg in 20 w/v % barium solution, about 9.21 mmHg in 30 w/v % barium solution, and about 9.72 mmHg 40 w/v % barium solution. 5. Intraluminal pressure difference between the barium reduction and the air reduction is probably of the major causes of rapid diagnosis and high reduction rate in the air reduction.

1990-01-01

To evaluate the effects of irradiation on heterotopically placed vascularized knee isografts, a single dose of 10 Gy of total-body irradiation was given to Lewis donor rats. Irradiation was delivered either 2 or 6 days prior to harvesting or subsequent transplantation, and evaluated at 1, 2, and 4 weeks after grafting. Irradiation caused endothelial depopulation of the graft artery, although vascular pedicle patency was maintained throughout the study. Bone graft viability and mineralization were normal. Dramatic changes in the bone marrow were seen that included an increase of its fat content (P less than 0.001), and a concomitant decrease in bone marrow-derived immunocompetent cells. These changes were more prominent in recipients of grafts from day -6 irradiated donor rats. Total-body irradiation did not prejudice the use of vascularized bone grafts, and exhibited an associated immunosuppresant effect over the vascular endothelium and bone marrow. This may be a further rational conditioning procedure to avoid recipient manipulation in vascularized bone allotransplantation

Incidental gastrointestinal findings are commonly detected on MDCT exams performed for various medical indications. This review describes the radiological MDCT spectrum of appearances already present in the past literature and in today's experience of several gastrointestinal acute conditions such as abdominal hernia, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies which can require medical and surgical intervention or clinical follow-up. The clinical presentation of this illness is frequently nonspecific: abdominal pain, distension, nausea, fever, rectal bleeding, vomiting, constipation, or a palpable mass, depending on the disease. A proper differential diagnosis is essential in the assessment of treatment and in this case MDCT exam plays a central rule. We wish that this article will familiarize the radiologist in the diagnosis of this kind of incidental MDCT findings for better orientation of the therapy. PMID:28638830

Incidental gastrointestinal findings are commonly detected on MDCT exams performed for various medical indications. This review describes the radiological MDCT spectrum of appearances already present in the past literature and in today's experience of several gastrointestinal acute conditions such as abdominal hernia, giant colon diverticulum, GIST, intestinal pneumatosis, colon ischemia, cold intussusception, gallstone ileus, and foreign bodies which can require medical and surgical intervention or clinical follow-up. The clinical presentation of this illness is frequently nonspecific: abdominal pain, distension, nausea, fever, rectal bleeding, vomiting, constipation, or a palpable mass, depending on the disease. A proper differential diagnosis is essential in the assessment of treatment and in this case MDCT exam plays a central rule. We wish that this article will familiarize the radiologist in the diagnosis of this kind of incidental MDCT findings for better orientation of the therapy.

To describe the characteristics of neurogenic heterotopic ossification (NHO) based on clinical tests, electroneuromyography (ENMG) and CT in a database of patients with lesions of the central nervous system who required sciatic nerve neurolysis along with posterior hip NHO resection, and to determine the respective roles of ENMG and CT in the management of posterior hip NHOs in patients who are unable to communicate or express pain. The consistency of the ENMG results with clinical findings, CT results and macroscopic signs of lesions was retrospectively assessed after sciatic nerve neurolysis and ablation of 55 posterior hip NHOs. Sciatic nerve neurolysis was necessary in 55 cases (47.4 %; 55 out of 116). CT showed contact of the NHO with the nerve in all cases: 5 in contact with no deflection, 3 in contact with deflection, 21 moulded into a gutter and 26 entrapped in the NHO. There were clinical signs of sciatic nerve lesion in 21.8 % of cases (12 out of 55). ENMG showed signs of sciatic nerve lesions in only 55.6 % (10 out of 18), only 4 of whom presented with clinical signs of a nerve lesion. No significant relationship was found between clinical symptoms and ENMG findings of sciatic nerve compression (n = 13, p = 0.77). Nerve compression by NHO is likely an underdiagnosed condition, particularly in patients who are unable to communicate. Diagnosis of sciatic compression by NHO should be based on regular clinical examinations and CT. ENMG is not sufficiently sensitive to be used alone for surgical decision-making. (orig.)

Purpose: Heterotopic ossification (HO) is a common problem following surgical repair of traumatic acetabular fracture (TAF), potentially causing severe pain and decreased range of motion. This report analyzes the role of radiation therapy for prevention of HO in TAF. Methods and Materials: The charts of all patients who received RT to the hip following TAF repair between July 1988 and January 1998 were reviewed. Sixty-six patients were identified. RT was given in 5 fractions of 2 Gy in 45 patients, 1 fraction of 8 Gy in 17 patients, and other doses in 4 patients. Treatment fields encompassed peri acetabular tissues at highest risk for HO. Time to RT was ≤ 24 hours for 46 patients. Results: Radiographic follow-up at least 6 months following RT was available in 47/66 (71%) patients to permit Brooker classification, revealing 6 cases (13%) of Grade III HO, compared to historical incidence in this population of 50%. No Grade IV HO was found. Mean follow-up was 18 months. Four of the Grade III patients had received 10 Gy/5 fractions, and 2 received 8 Gy/1 fraction. Postoperative wound infection occurred in 6 patients, and osteonecrosis of the femoral head was found in 13. Conclusions: RT following surgical repair of TAF provides effective prophylaxis against formation of clinically significant HO. We recommend a single fraction of 7-8 Gy within 24 hours of surgery to prevent HO formation and minimize patient discomfort

Noroviruses (NoVs) have been recognized as a leading cause of sporadic cases and outbreaks of acute gastroenteritis in all age groups. During the surveillance of NoVs in Chiang Mai, Thailand, four cases of the novel GII.17 NoVs were sporadically detected by RT-PCR in 2014-2015. The first case of GII.17 was detected in a healthy adult who worked for a restaurant. The second case was found in a pediatric patient who admitted to the hospital with intussusception. The third and fourth cases were found in acute gastroenteritis children. Phylogenetic analysis clearly demonstrated that GII.17 NoVs detected in this study were genetically closely related with the novel GII.17 Kawasaki reference strains. These four GII.17 NoV positive specimens were also tested by two immunochromatographic test kits in order to evaluate the sensitivity for GII.17 NoV detection. The viral loads in those specimens were determined by real-time RT-PCR. The sensitivity of GII.17 NoV detection varies by individual test kits and also depending on the amount of the viruses contained in the fecal specimens. In summary, our study reported the detection of novel GII.17 NoVs in a wide range of subjects with and without diarrhea. Therefore, continued comprehensive screening and genetic molecular characterization of NoV strains circulating in this area need to be further investigated. Copyright © 2016 Elsevier B.V.

Heterotopic ossification (HO) is defined as a formation of bone outside the skeletal system. The reported HO occurrence rate in cervical artificial disc replacement (ADR) is unexpectedly high and is known to vary. However, the predisposing factors for HO in cervical ADR have not yet been elucidated. Investigation of the predisposing factors of HO in cervical arthroplasty and the relationship between degeneration of the cervical spine and HO occurrence. Retrospective study to discover predisposing factors of HO in cervical arthroplasty. A total of 170 patients who underwent cervical ADR were enrolled including full follow-up clinical and radiologic data. Radiologic outcomes were assessed by identification of HOs according to McAfee's classifications. This study enrolled a total of 170 patients who underwent cervical ADR. Pre-existing degenerative change included anterior or posterior osteophytes, ossification of the anterior longitudinal ligament, posterior longitudinal ligament, or ligamentum nuchae. The relationships between basic patient data, pre-existing degenerative change, and HO were investigated using linear logistic regression analysis. Among all 170 patients, HO was found in 69 patients (40.6%). Among the postulated predisposing factors, only male gender and artificial disc device type were shown to be statistically significant. Unexpectedly, preoperative degenerative changes in the cervical spine exerted no significant influence on the occurrence of HOs. The odds ratio of male gender compared with female gender was 2.117. With regard to device type, the odds ratios of Mobi-C (LDR medical, Troyes, France) and ProDisc-C (Synthes, Inc., West Chester, PA, USA) were 5.262 and 7.449, respectively, compared with the Bryan disc. Definite differences in occurrence rate according to the gender of patients and the prosthesis type were identified in this study. Moreover, factors indefinably expected to influence HO in the past were not shown to be risk factors

Heterotopic pregnancy after in vitro fertilization and embryo transfer: the role of routine transvaginal ultrasonography

Spontaneous heterotopic pregnancy (HP) is a rare condition, however, the rising incidence after in-vitro fertilization and embryo transfer (IVF-ET) may present serious problems as the diagnosis of this potentially fatal condition is often missed. The purposes of this study were to investigate the frequency of HP after IVF-ET, to analyze the clinical presentation and the outcome of coincidental intrauterine pregnancy, and to evaluate the value of routine transvaginal ultrasonography in early diagnosis and treatment of HP. There were 11 cases of HP among 484 pregnancies after IVF-ET (The incidence was 2.3%) in recent 2 years. We evaluated the clinical findings and the findings of transvaginal sonography in those 11 patients. The combined extrauterine pregnancies were tubal (n = 9), cornual (n = 1), and both the tubal and cornual (n = 1). Vaginal bleeding was absent in 4 cases and one of them was asymptomatic. HP may be suspected if there was an elevated serum hCG in the absence of intrauterine multiple gestations. In all cases, the condition was diagnosed by transvaginal sonography performed prior to surgical intervention. The coincidental intrauterine pregnancies were ended in successful full-term delivery in 7 cases, while one pregnancy was ongoing at that time. The incidence of HP was evidently higher in IVF-ET than in spontaneous pregnancies. Transvaginal sonography was useful in accurate diagnosis in clinically suspected cases and even in asymptomatic cases. Routine transvaginal sonography played an important role in early diagnosis and prompt management of HP

The appendiceal intussusception is a rare entity. Usually there is a predisposing factor such as a tumor, mucocele, etc. We report the case of a 61 years old female patient, with recurrent abdominal pain, localized in the right lower quadrant. We performed different diagnostic imaging exams including: double-contrast barium enema, enteroclysis, ultrasonography, computed tomography and magnetic resonance. After endoscopy a surgical procedure removed the appendix. The pathological anatomy confirmed the diagnosis of an appendiceal intussusception, complicated with a chronic inflammatory process. Appendiceal intussusception and chronic appendicitis are infrequent; it is even more uncommon the association of both entities. In addition, it was not found a predisposing cause to intussusception. For the reasons described above, we conclude that this case is an unusual presentation of appendiceal intussusception, not previously reported. (author)

Cost of Radiotherapy Versus NSAID Administration for Prevention of Heterotopic Ossification After Total Hip Arthroplasty

Purpose: Heterotopic ossification (HO), or abnormal bone formation, is a common sequela of total hip arthroplasty. This abnormal bone can impair joint function and must be surgically removed to restore mobility. HO can be prevented by postoperative nonsteroidal anti-inflammatory drug (NSAID) use or radiotherapy (RT). NSAIDs are associated with multiple toxicities, including gastrointestinal bleeding. Although RT has been shown to be more efficacious than NSAIDs at preventing HO, its cost-effectiveness has been questioned. Methods and Materials: We performed an analysis of the cost of postoperative RT to the hip compared with NSAID administration, taking into account the costs of surgery for HO formation, treatment-induced morbidity, and productivity loss from missed work. The costs of RT, surgical revision, and treatment of gastrointestinal bleeding were estimated using the 2007 Medicare Fee Schedule and inpatient diagnosis-related group codes. The cost of lost wages was estimated using the 2006 median salary data from the U.S. Census Bureau. Results: The cost of administering RT was estimated at $899 vs. $20 for NSAID use. After accounting for the additional costs associated with revision total hip arthroplasty and gastrointestinal bleeding, the corresponding estimated costs were $1,208 vs. $930. Conclusion: If the costs associated with treatment failure and treatment-induced morbidity are considered, the cost of NSAIDs approaches that of RT. Other NSAID morbidities and quality-of-life differences that are difficult to quantify add to the cost of NSAIDs. These considerations have led us to recommend RT as the preferred modality for use in prophylaxis against HO after total hip arthroplasty, even when the cost is considered

To determine the risk of radiation-induced malignancy after prophylactic treatment for heterotopic ossification (HO). A matched case-control study was conducted within a population-based cohort of 3489 patients treated either for acetabular fractures with acetabular open reduction internal fixation or who underwent total hip arthroplasty from 1990 to 2009. Record-linkage techniques identified patients who were diagnosed with a malignancy from our state health registry. Patients with a prior history of malignancy were excluded from the cohort. For each documented case of cancer, 2 controls were selected by stratified random sampling from the cohort that did not develop a malignancy. Matching factors were sex, age at time of hip treatment, and duration of follow-up. A total of 243 patients were diagnosed with a malignancy after hip treatment. Five patients were excluded owing to inadequate follow-up time in the corresponding control cohort. A cohort of 238 cases (control, 476 patients) was included. Mean follow-up was 10 years, 12 years in the control group. In the cancer cohort, 4% of patients had radiation therapy (RT), compared with 7% in the control group. Of the 9 patients diagnosed with cancer after RT, none occurred within the field. The mean latency period was 5.9 years in the patients who received RT and 6.6 years in the patients who did not. Median (range) age at time of cancer diagnosis in patients who received RT was 62 (43-75) years, compared with 70 (32-92) years in the non-RT patients. An ad hoc analysis was subsequently performed in all 2749 patients who were not matched and found neither an increased incidence of malignancy nor a difference in distribution of type of malignancy. We were unable to demonstrate an increased risk of malignancy in patients who were treated with RT for HO prophylaxis compared with those who were not. Copyright © 2014 Elsevier Inc.

VIII, VEGF and SMCA. Proliferating cells were detected in follicles, and the rate of apoptosis was minimal in ovaries of control and autotransplanted ovaries. Conclusion These data demonstrate successful autotransplantation of a portion of frozen/thawed ovaries manifested by restoration of selected ovarian function including in vitro maturation of collected oocytes, presence of follicles from several stages of folliculogenesis and blood vessels expressing specific markers of vascularization, and proliferation and apoptosis of ovarian cells. Thus, heterotopic autotransplantation of a whole frozen/thawed ovary allows for development of preovulatory follicles, oocyte growth, and for restoration of vascularization and cellular function. However, additional improvements are required to enhance the efficiency of autotransplantation of frozen/thawed ovaries to produce more oocytes.

Purpose Diffusion tensor imaging provides better understanding of pathophysiology of congenital anomalies, involving central nervous system. This study was aimed to specify the pathogenetic mechanism of heterotopia, proved by diffusion tensor imaging, and establish new findings of heterotopia on fractional anisotropy maps. Materials and Methods Diffusion-weighted imaging data from 11 patients (M : F = 7 : 4, aged from 1 to 22 years, mean = 12.3 years) who visited the epilepsy clinic and received a routine seizure protocol MRI exam were retrospectively analyzed. Fractional anisotropy (FA) maps were generated from diffusion tensor imaging of 11 patients with heterotopia. Regions of interests (ROI) were placed in cerebral cortex, heterotopic gray matter and deep gray matter, including putamen. ANOVA analysis was performed for comparison of different gray matter tissues. Results Heterotopic gray matter showed signal intensities similar to normal gray matter on T1 and T2 weighted MRI. The measured FA of heterotopic gray matter was higher than that of cortical gray matter (0.236 ± 0.011 vs. 0.169 ± 0.015, p < 0.01, one way ANOVA), and slightly lower than that of deep gray matter (0.236 ± 0.011 vs. 0.259 ± 0.016, p < 0.01). Conclusion Increased FA of heterotopic gray matter suggests arrested neuron during radial migration and provides better understanding of neurodevelopment. PMID:20499428

Because of the difficulty associated with making an accurate diagnosis of gastric heterotopic pancreas (HP) before surgery, surgical resection is usually performed in suspected cases. However, this is an invasive procedure and prone to certain surgical complications. This study was designed to evaluate the feasibility of endoscopic excavation for gastric HP, as well as the value of endoscopic ultrasonography (EUS) in diagnosing gastric HP. Between January 2007 and January 2013, 42 consecutive patients with gastric HP were enrolled in this retrospective study. Key steps: (1) Injection of a solution (100 ml saline + 2 ml indigo carmine + 1 ml epinephrine) into the submucosal layer after making several dots around the lesion; (2) Incision of the mucosa outside the marker dots with a needle-knife, and then circumferential excavation until complete resection of the lesion; (3) Closure of the artificial ulcer with several clips after tumor removal. In this study, 18 cases (42.9%) were suspected as gastric HP (assessed by two experienced endoscopists before endoscopic excavation), 8 (19.0%) were suspected as gastrointestinal stromal tumors, 7 (16.7%) as gastric polyp, and the remaining 9 cases (21.4%) were still unknown. The mean procedure duration was 28.6 min. En bloc resection by endoscopic excavation was achieved in 40 cases (95.2%), and no massive bleeding, delayed bleeding, perforation, or other severe complication occurred in these patients. Among the 42 lesions, a tube echo could be detected in 11 cases by EUS. Those 11 cases were diagnosed as gastric HP by histopathology. Endoscopic excavation appears to be a safe and feasible procedure for accurate histopathologic evaluation and curative treatment in gastric HP. Use of EUS has some value in the diagnosis of gastric HP before the procedure

Purpose: Radiation therapy (RT) is frequently administered to prevent heterotopic ossification (HO) after total hip arthroplasty (THA). The purpose of this study was to determine if there is an increased risk of HO after RT prophylaxis with shielding of the THA components. Methods and Materials: This is a retrospective analysis of THA patients undergoing RT prophylaxis of HO at Brigham and Women's Hospital between June 1994 and February 2004. Univariate and multivariate logistic regressions were used to assess the relationships of all variables to failure of RT prophylaxis. Results: A total of 137 patients were identified and 84 were eligible for analysis (61%). The median RT dose was 750 cGy in one fraction, and the median follow-up was 24 months. Eight of 40 unshielded patients (20%) developed any progression of HO compared with 21 of 44 shielded patients (48%) (p = 0.009). Brooker Grade III-IV HO developed in 5% of unshielded and 18% of shielded patients (p 0.08). Multivariate analysis revealed shielding (p = 0.02) and THA for prosthesis infection (p = 0.03) to be significant predictors of RT failure, with a trend toward an increasing risk of HO progression with age (p = 0.07). There was no significant difference in the prosthesis failure rates between shielded and unshielded patients. Conclusions: A significantly increased risk of failure of RT prophylaxis for HO was noted in those receiving shielding of the hip prosthesis. Shielding did not appear to reduce the risk of prosthesis failure

Retrospective study of the difference of heterotopic ossification (HO) occurrence according to 3 different types of prosthesis. This study was designed to investigate the difference of HO occurrence according to different type of prosthesis. HO is defined as formation of the bone outside the skeletal system. Reported HO occurrence rate in cervical artificial disc replacement (ADR) was unexpectedly high and varied. But the influencing factors of HO in cervical ADR have not been elucidated well. The prosthesis-related factors for making difference of HO occurrence were investigated in this study. A total of 170 patients undergoing cervical arthroplasty with the Bryan cervical disc prosthesis (Medtroic Sofamor Danek, Memphis, TN), Mobi-C disc prosthesis (LDR Medical, Troyes, France), and ProDisc-C (Synthes, Inc., West Chester, PA) were included. Cervical lateral radiographs obtained before and after surgery were used to identify HO. Occurrence rate, occurrence-free period, location, and grade of HOs were investigated according to the different prosthesis. Each prosthesis group included patients as follows: Bryan disc, 81 patients; Mobi-C, 61 patients; and ProDisc-C, 28 patients. Overall HO rate was 40.6% (69 of 170 patients). Each HO occurrence rate by prosthesis was as follows: the Bryan disc group, 21.0%; Mobi-C group, 52.5%; and the ProDisc-C group, 71.4%. In the survival analysis, all patients showed 27.1 +/- 3.7 months as the median survival. The Bryan disc group showed statistically longer survival (48.4 +/- 7.4 months) than the other groups. Occurrence of HO is an inevitable postoperative complication after cervical ADR. The occurrence rate of HO was higher than our expectation. Moreover, definite differences in occurrence rate according to the prosthesis type were identified by this study.

Summary The Authors present a case of heterotopic central nervous system tissue observed in an 81-year-old male in the form of an ethmoidal polyp. A review of the literature indicates that this is a rare condition characterised by a connective tissue lesion with astrocytic and oligodendrocytic glial cells, which may be located outside the nasal pyramid in some cases and inside the nasal cavity in others. The most important diagnostic aspect involves differentiating these from meningoencephalocele, which maintains an anatomical connection with central nervous system tissue. Contrast-enhanced imaging is essential for diagnosis, as in cases of heterotopic central nervous system tissue, it will demonstrate that there are no connections with intra-cranial tissue. Endoscopic excision is the treatment of choice. PMID:20161881

Heterotopic ossification (HO) of the bone is defined as a benign condition in which abnormal bone formation occurs in soft tissue. One of the most common prophylactic treatments for HO is radiation therapy (RT). This study retrospectively reviewed 20 patients younger than the age of 40 who received radiation to prevent HO in a single fraction of 7 Gray. The purpose of this study is to assess the risk of a second malignancy in these patients by recreating their treatment fields and contouring organs at risk to estimate the radiation dose absorbed by normal tissues outside the radiation treatment field. Diagnostic computed tomography (CT) scans for each patient were used to recreate treatment fields and to calculate dose to structures of interest. The distance from the field edge to each structure and its depth was recorded. Dose measurements in a water phantom were performed for the range of depths, distances, and field sizes used in the actual treatment plans. Computer-generated doses were compared to estimates based on measurement. The structure dose recorded was the higher dose generated between the 2 methods. Scatter dose was recorded to the rectum, bladder, sigmoid colon, small bowel, ovaries and utero-cervix in female patients, and prostate and gonads in male patients. In some patients, there is considerable dose received by certain organs from scatter because of their proximity to the radiation field. The average dose to the ovarian region was 4.125 Gy with a range of 1.085 to 6.228 Gy. The risk estimate for these patients ranged from 0.16% to 0.93%. The average total lifetime risk estimate for the bladder in all patients is 0.22% and the average total lifetime risk estimate for the remainder organs in all patients is 1.25%. In conclusions, proper shielding created from multileaf collimators (MLCs), blocks, and shields should always be used when possible.

Purpose: The functional failure induced by heterotopic ossification (HO) following total hip arthroplasty (THA) was analyzed and correlated to the radiologic failure. Patients and methods: From July 1997 to July 2001, 315 patients (345 hips) received THA indicated by a hypertrophic osteoarthritis of higher degree (Kellgren grade III, IV). All patients were irradiated prophylactically for prevention of HO on the evening before surgery with a 7-Gy single fraction. The patients' median age was 66.3 years. Radiologic failure was assessed by comparison of pre- and postoperative hip X-rays (immediately and 6 months after surgery). Analysis of radiographs was performed according to the Brooker Score. Clinical failure was appraised by measurement of passive range of motion (ROM) of the hip joint with a standard goniometer. The t-test was used for statistical analysis. Results: 281 patients (81.5%) did not develop HO. HO of Brooker grade I or II was found in 58 patients (16.8%). Six patients (1.7%) developed HO Brooker grade III or IV. There was a significant negative correlation between the degree of radiologic and clinical failure. ROM differed significantly between patients with HO Brooker grade 0, I, II and patients with HO Brooker grade III, IV. Comparing the pre- and postoperative ROM, all patients with Brooker grade 0, I and II showed a significant improvement of flexion, internal and external rotation, abduction and adduction movement. Patients with HO Brooker grade III and IV showed no improvement of ROM in the postoperative follow-up. Conclusion: The development of HO following THA influences the physical function of the hip joint dependent on the degree of ossification. HO of lower degree (Brooker I, II) does not influence the clinical outcome, whereas HO of higher degree (Brooker III, IV) reduces the function of hip arthroplasty. Therefore, the purpose of a prophylactic therapy must be to reduce HO of higher degree. (orig.)

[Appendectomy for appendicitis by colonoscopy after a cecal invagination of the appendix during childhood].

2007-01-01

Appendiceal intussusception (the inside-out appendix) was often practiced in pediatric surgery when the appendectomy was performed during laparotomy. Complications are exceptional. We report the first case of appendiceal intussusception in an adult appendectomized by this procedure during childhood, reviewing the radiological aspect, pathogenesis, and treatment. This delayed complication of appendiceal intussusception should be known to the surgeon. Treatment during colonoscopy is possible. This inflammation of the vaginated appendix can be prevented by coagulating the appendicular vessels to the serous membrane before turning it inside-out.

The aim of this study was to investigate the association between the magnitude of anti-nociceptive effects induced by heterotopic noxious counter-stimulation (HNCS) and the basal μ-opioid receptor availability in the amygdala. In 8 healthy volunteers (4 females and 4 males), transcutaneous electrical stimulation was applied to the right sural nerve to produce the nociceptive flexion reflex (RIII-reflex), moderate pain, and scalp somatosensory evoked potentials (SEPs). Immersion of the left hand in cold water for 20min was used as HNCS. In a separate session, basal μ-opioid receptor availability was measured using positron emission tomography with the radiotracer [(11)C]carfentanil. HNCS produced a reduction of the P260 amplitude (pbasal μ-opioid receptor availability in the amygdala on the right (R(2)=0.55, p=0.03) with a similar trend on the left (R(2)=0.24, p=0.22). Besides, HNCS did not induce significant changes in pain and RIII-reflex amplitude (p>0.05). These results suggest that activation of μ-opioid receptors in the amygdala may contribute to the anti-nociceptive effects of HNCS. The lack of RIII-reflex modulation further suggests that μ-opioid receptor activation in the amygdala contributes to decrease pain-related brain activity through a cerebral mechanism independent of descending modulation.

Purpose: Heterotopic ossification (HO) is a frequent complication following total hip arthroplasty. This study was conducted to calculate the radiation dose to organs-at-risk and estimate the probability of cancer induction from radiotherapy for HO prophylaxis.Methods: Hip irradiation for HO with a 6 MV photon beam was simulated with the aid of a Monte Carlo model. A realistic humanoid phantom representing an average adult patient was implemented in Monte Carlo environment for dosimetric calculations. The average out-of-field radiation dose to stomach, liver, lung, prostate, bladder, thyroid, breast, uterus, and ovary was calculated. The organ-equivalent-dose to colon, that was partly included within the treatment field, was also determined. Organ dose calculations were carried out using three different field sizes. The dependence of organ doses upon the block insertion into primary beam for shielding colon and prosthesis was investigated. The lifetime attributable risk for cancer development was estimated using organ, age, and gender-specific risk coefficients.Results: For a typical target dose of 7 Gy, organ doses varied from 1.0 to 741.1 mGy by the field dimensions and organ location relative to the field edge. Blocked field irradiations resulted in a dose range of 1.4–146.3 mGy. The most probable detriment from open field treatment of male patients was colon cancer with a high risk of 564.3 × 10{sup −5} to 837.4 × 10{sup −5} depending upon the organ dose magnitude and the patient's age. The corresponding colon cancer risk for female patients was (372.2–541.0) × 10{sup −5}. The probability of bladder cancer development was more than 113.7 × 10{sup −5} and 110.3 × 10{sup −5} for males and females, respectively. The cancer risk range to other individual organs was reduced to (0.003–68.5) × 10{sup −5}.Conclusions: The risk for cancer induction from radiation therapy for HO prophylaxis after total hip arthroplasty varies considerably by

Full Text Available PJS is an autosomal dominant genetic disease associated with melanin pigment spots on the oral mucosa, lips, nasal alae, palm and soles, as well as hamartomatous polyps in the alimentary canal. Polyps are often a cause of intussusception in the affected patients. Cancers of gastrointestinal system, uterus and breast are common in patients with PJS. Long-term follow-up is required to prevent intussusception in children and cancer in adults. We report a classical case of Peutz–Jeghers syndrome presenting with jejunoileal intussusception in a 9 year old child.

Early treatment of heterotopic ossification (HO) is currently limited by delayed diagnosis due to limited visualization at early time points. In this study, we validate the use of spectral ultrasound imaging (SUSI) in an animal model to detect HO as early as one week after burn tenotomy. Concurrent SUSI, micro CT, and histology at 1, 2, 4, and 9weeks post-injury were used to follow the progression of HO after an Achilles tenotomy and 30% total body surface area burn (n=3-5 limbs per time point). To compare the use of SUSI in different types of injury models, mice (n=5 per group) underwent either burn/tenotomy or skin incision injury and were imaged using a 55MHz probe on VisualSonics VEVO 770 system at one week post injury to evaluate the ability of SUSI to distinguish between edema and HO. Average acoustic concentration (AAC) and average scatterer diameter (ASD) were calculated for each ultrasound image frame. Micro CT was used to calculate the total volume of HO. Histology was used to confirm bone formation. Using SUSI, HO was visualized as early as 1week after injury. HO was visualized earliest by 4weeks after injury by micro CT. The average acoustic concentration of HO was 33% more than that of the control limb (n=5). Spectroscopic foci of HO present at 1week that persisted throughout all time points correlated with the HO present at 9weeks on micro CT imaging. SUSI visualizes HO as early as one week after injury in an animal model. SUSI represents a new imaging modality with promise for early diagnosis of HO. Copyright © 2018 Elsevier Inc.

Purpose: To ascertain whether the time from injury to prophylactic radiation therapy (RT) influences the rate of heterotopic ossification (HO) after operative treatment of displaced acetabular fractures. Methods and Materials: This is a single-institution, retrospective analysis of patients referred for RT for the prevention of HO. Between January 2000 and January 2009, 585 patients with displaced acetabular fractures were treated surgically followed by RT for HO prevention. We analyzed the effect of time from injury on prevention of HO by RT. In all patients, 700 cGy was prescribed in a single fraction and delivered within 72 hours postsurgery. The patients were stratified into five groups according to time interval (in days) from the date of their accident to the date of RT: Groups A {<=}3, B {<=}7, C {<=}14, D {<=}21, and E >21days. Results: Of the 585 patients with displaced acetabular fractures treated with RT, (18%) 106 patients developed HO within the irradiated field. The risk of HO after RT increased from 10% for RT delivered {<=}3 days to 92% for treatment delivered >21 days after the initial injury. Wilcoxon test showed a significant correlation between the risk of HO and the length of time from injury to RT (p < 0.0001). Chi-square test and multiple logistic regression analysis showed no significant association between all other factors and the risk of HO (race, gender, cause and type of fracture, surgical approach, or the use of indomethacin). Conclusions: Our data suggest that there is higher incidence and risk of HO if prophylactic RT is significantly delayed after a displaced acetabular fracture. Thus, RT should be administered as early as clinically possible after the trauma. Patients undergoing RT >3 weeks from their displaced acetabular fracture should be informed of the higher risk (>90%) of developing HO despite prophylaxis.

Full Text Available Background/Aim. Heterotopic ossification (HO is an important complication of head and spinal cord injuries (SCI. Pulse low-intensity electromagnetic field (PLIMF therapy increases blood flow to an area of pain or inflammation, bringing more oxygen to that area and helps to remove toxic substances. The aim of this study was to determine the effect of PLIMF as prophylaxis of HO in patients with SCI. Methods. This prospective random control clinical study included 29 patients with traumatic SCI. The patients were randomly divided into experimental (n = 14 and control group (n = 15. The patients in the experimental group, besides exercise and range of motion therapy, were treated by PLIMF of the following characteristics: induction of 10 mT, frequency of 25 Hz and duration of 30 min. Pulse low-intensity electromagnetic field therapy started in the 7th week after the injury and lasted 4 weeks. The presence or absence of HO around the patients hips we checked by a plane radiography and Brookers classification. Functional capabilities and motor impairment were checked by Functional Independent Measure (FIM, Barthel index and American Spinal Injury Association (ASIA impairment class. Statistic analysis included Kolmogorov-Smirnov test, Shapiro-Wilk test, Mann Whitney Exact test, Exact Wilcoxon signed rank test and Fischer Exact test. Statistical significance was set up to p < 0.05. Results. At the end of the treatment no patient from the experimental group had HO. In the control group, five patients (33.3% had HO. At the end of the treatment the majority of the patients from the experimental group (57.14% moved from ASIA-A to ASIA-B class. Conclusion. Pulse low-intensity electromagnetic field therapy could help as prophylaxis of HO in patients with traumatic SCI.

Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder and the most disabling condition of heterotopic (extraskeletal) ossification in humans. Extraskeletal bone formation associated with inflammation preceding the osseous conversion usually begins in the first decade, predominantly in the head, neck, and shoulders. All patients have malformed great toes. Most patients have a spontaneous mutation of the ACVR1 gene. We report a 17-year-old girl with malformed great toes who had her first episode of heterotopic ossification and impaired mobility of the left hip at the age of 13 years. No inflammatory fibroproliferative masses preceded the onset of heterotopic ossification. Radiographic studies demonstrated myositis ossificans, but failure to associate the great toe malformation with heterotopic ossification led to a failure to diagnose FOP. She underwent repeated and unnecessary operative procedures to remove a recurrent lesion. FOP was finally suspected when the great toe malformation was correlated with the trauma-induced heterotopic ossification. Genetic analysis confirmed the presence of the classic FOP mutation (ACVR1 c.617G>A; R206H). This case highlights the importance of examining the great toes in anyone with heterotopic ossification. The association of malformations of the great toe with heterotopic ossification in all cases of classic FOP will lead to prompt clinical diagnosis and the prevention of iatrogenic harm.

Ninety-seven high risk hips were irradiated postoperatively for prevention of heterotopic bone (HTB) in the UCLA Department of Radiation Oncology from 1980 to 1988. Ninety-two hips in 82 patients were eligible for analysis with a minimum follow-up of 2 months and a median follow-up of 10 months. Forty-nine of the hips had porous coated ingrowth prostheses. From 1980 to 1986, 2 Gy fractions were used to deliver 20 Gy (8 hips), 12 Gy (1 hip), and 10 Gy (27 hips). Since December of 1986, 38 hips received 8 Gy in two increments and 18 hips received a single 7 Gy fraction. All porous ingrowth components were shielded with custom blocks. Six out of 92 hips developed clinically significant. There was one clinically significant failure in 78 hips (1.3%) when irradiation was initiated before post-operative day (POD) No.6 and shielding was properly placed. One clinical failure occurred in 38 hips which received 8 Gy in two increments. One clinical failure occurred out of the 18 hips treated with 7 Gy in one fraction. This failure could be related to block malposition. There were four clinical failures in the 36 hips treated with 2 Gy fractions to total doses of 10 Gy, 12 Gy, or 20 Gy. Three of these failures were associated with initiation of treatment after POD No.5, and the fourth was related to block malposition. Unshielded trochanteric osteotomies resulted in five migrations and seven fibrous unions for a total non-osseous union rate of 12/36 (33%). Shielding of the remaining 28 trochanteric osteotomies resulted in a non-osseous union rate of 7%. There were no failures of union of components, and the only side effects noted in the series were the five trochanteric migrations. In conclusion, the use of 8 Gy in two increments or 7 Gy in one fraction was found to be as efficacious as conventional 2 Gy fractionation schemes with no increase in side effects

To analyze the association between cystic dystrophy in the heterotopic pancreas (CDHP) and minor papilla abnormalities. Seventy-six patients with CDHP were retrospectively included over 14 years. Two radiologists searched for MDCT signs of CDHP (cysts and thickened intestinal wall, inflammatory changes), and minor papilla abnormalities (Santorini duct dilatation, luminal calcifications of the minor papilla). Other pancreatic abnormalities (parenchymal calcifications, main pancreatic duct dilatation) or bile duct dilatation were also analysed. CDHP was mostly located in the second part of the duodenum (71/76, 93.5 %). Median duodenal wall thickness was 20 mm (range 10-46). There were multiple cysts in 86 % (65/76, median = 3), measuring 2-60 mm. No cysts were identified in four patients (5 %). Inflammatory changes were found in 87 % (66/76). Minor papilla abnormalities were found in 37 % (28/76) and calcifications in the minor papilla without calcifications in the major papilla were only observed in three patients (4 %). Abnormalities of the pancreas and main bile duct dilatation were identified in 78 % (59/76) and 38 % (29/76). Previously described CT features were seen in most patients with CDHP. However, minor papilla abnormalities were seen in a minority of patients and, therefore, do not seem to be a predisposing factor for CDHP. (orig.)

Removing the age restrictions for rotavirus vaccination: a benefit-risk modeling analysis.

Directory of Open Access Journals (Sweden)

Manish M Patel

Full Text Available BACKGROUND: To minimize potential risk of intussusception, the World Health Organization (WHO recommended in 2009 that rotavirus immunization should be initiated by age 15 weeks and completed before 32 weeks. These restrictions could adversely impact vaccination coverage and thereby its health impact, particularly in developing countries where delays in vaccination often occur. METHODS AND FINDINGS: We conducted a modeling study to estimate the number of rotavirus deaths prevented and the number of intussusception deaths caused by vaccination when administered on the restricted schedule versus an unrestricted schedule whereby rotavirus vaccine would be administered with DTP vaccine up to age 3 years. Countries were grouped on the basis of child mortality rates, using WHO data. Inputs were estimates of WHO rotavirus mortality by week of age from a recent study, intussusception mortality based on a literature review, predicted vaccination rates by week of age from USAID Demographic and Health Surveys, the United Nations Children's Fund (UNICEF Multiple Indicator Cluster Surveys (MICS, and WHO-UNICEF 2010 country-specific coverage estimates, and published estimates of vaccine efficacy and vaccine-associated intussusception risk. On the basis of the error estimates and distributions for model inputs, we conducted 2,000 simulations to obtain median estimates of deaths averted and caused as well as the uncertainty ranges, defined as the 5th-95th percentile, to provide an indication of the uncertainty in the estimates. We estimated that in low and low-middle income countries a restricted schedule would prevent 155,800 rotavirus deaths (5th-95th centiles, 83,300-217,700 while causing potentially 253 intussusception deaths (76-689. In contrast, vaccination without age restrictions would prevent 203,000 rotavirus deaths (102,000-281,500 while potentially causing 547 intussusception deaths (237-1,160. Thus, removing the age restrictions would avert an

Full Text Available Developmental malformations are brain abnormalities that occur during embryogenesis. Neuronal migration disorders, including heterotopic lesions, constitute one type of such abnormalities. The aim of the study was to compare the epileptic clinical patterns of patients with periventricular nodular heterotopia (PNH (G1 with those affected by subcortical heterotopia (SCH (G2 looking for differences between both groups which, eventually, might suggest the type of the underlying malformation. The variables studied in both groups were: type of the heterotopia depicted on MRI studies, sex, age, age at seizure onset, annual seizure frequency, localization of the ictal symptomatogenic zone, characteristics of the EEG, other associated anomalies on the magnetic resonance images (MRI besides the heterotopia, and response to treatment. The only difference found between both groups was the type of heterotopia as shown by MRI studies. The other assessed variables did not significantly (p>0.05 differ between groups. No differences in the clinical features characterizing epilepsy could be found in patients with PNH or SCH, being the images the only tool able to differentiate them.Las malformaciones de la corteza cerebral son un grupo de entidades que se producen durante las etapas del desarrollo embrionario y cuya manifestación clínica puede ser la epilepsia.

Idiopathic intussusception is an important cause of abdominal pain, bleeding per rectum and intestinal obstruction in infancy and childhood. The main aim of this study was to undertake a retrospective review of all chidren who presented with idiopathic intussusception over a 17-year period. The medical record of children who presented idiopathic intussusception from January 1984 to December 2000 at King Fahad National Guard Hospital ,Riyadh, Kingdom of Saudi Arabia were reviewed. The data obtained included age, sex clincal presentation, diagonstic investigations, mode of treatment, length of hospital stay and results. Thirty-three chidren (21 male, 12female) presented with 37 episodes of intussusception.Their mean age was 8.4 months (range 5 hours to 36 months ). Clinical features included rectal bleeding (81%), vomiting (78%), abdominal colic/pain (65%) and abdominal mass (62%) .All cases were ileocolic intussusception with no leading point. Barium enema was attempted in 36 cases with success in 20 (56%). Laparotomy was required in 16 csaes, manual reduction being successful in 11(30%) and 6 (16%) had bowel resection. At surgery, after attempted Barium reduction, 9(56%) cases had the intussusception already reduced to cecum. Seventy percent of the cases presented within 24 hours of onset of the symptoms.The 4 recurrences in 3 children had successful enema reduction. There was no mortality but 3 operative cases of this type required late surgery for adhesive intestinal obstruction including one requiring bowel resection. Idiopathic indussusception commonly presents as an ileo-colic type but is uncommon in our institution. The clinical features are classical, rectal bleeding being the most common. The majority presented within 24 hours of onset of symptoms and Barium enema reduction was sucessfull in 20 out of 36 cases in which it was attempted . Since most intussusception were already in the cecum at surgey after failed enema reduction could be considerd in stable

The primary aim of our study was to determine the interobserver agreement of defecography in diagnosing enterocele, anterior rectocele, intussusception, and anismus in fecal-incontinent patients. The subsidiary aim was to evaluate the influence of level of experience on interpreting defecography. Defecography was performed in 105 consecutive fecal-incontinent patients. Observers were classified by level of experience and their findings were compared with the findings of an expert radiologist. The quality of the expert radiologist's findings was evaluated by an intraobserver agreement procedure. Intraobserver agreement was good to very good except for anismus: incomplete evacuation after 30 sec (kappa, 0.55) and puborectalis impression (kappa, 0.54). Interobserver agreement for enterocele and rectocele was good (kappa, 0.66 for both) and for intussusception, fair (kappa, 0.29). Interobserver agreement for anismus: incomplete evacuation after 30 sec was moderate (kappa, 0.47), and for anismus: puborectalis impression was fair (kappa, 0.24). Agreement in grading of enterocele and rectocele was good (kappa, 0.64 and 0.72, respectively) and for intussusception, fair (kappa, 0.39). Agreement separated by experience level was very good for rectocele (kappa, 0.83) and grading of rectoceles (kappa, 0.83) and moderate for intussusception (kappa, 0.44) at the most experienced level. For enterocele and grading, experience level did not influence the reproducibility. Reproducibility for enterocele, anterior rectocele, and severity grading is good, but for intussusception is fair to moderate. For anismus, the diagnosis of incomplete evacuation after 30 sec is more reproducible than puborectalis impression. The level of experience seems to play a role in diagnosing anterior rectocele and its grading and in diagnosing intussusception.

Small bowel tumours are rare and comprise less than 2% of all primary gastrointestinal neoplasms. Among these tumours, a leiomyosarcoma belonging to soft tissue sarcomas is extremely rare and accounts for about 1 % of malignant mesenchymal lesions in the gastrointestinal tract. Due to its aggressive nature and slow growth, it is often diagnosed at the late stage when curative treatment is impossible. Authors report a first case of leiomyosarcoma with chronic recurrent ileocaecal intussusception and literature review to analyse diagnosis and treatment features of the ileum mesenchymal tumours. We present a case of an 87-year-old Caucasian man suffering from cramp-like abdominal pain for months. Due to lack of clinical signs and unspecific complaints, a diagnosis was delayed. Despite a detailed in-hospital examination, a proper diagnosis was established as late as during an operation. The patient was treated by surgery with good results. An uncommon laparoscopic resection of the small bowel with a tumour was performed. A histopathological investigation confirmed a very rare mesenchymal lesion of the distal ileum. The patient is under control with no recurrence for 1 year of the follow-up period. Reported case indicates that a usually asymptomatic tumour can cause uncommon chronic recurrent ileus signs. CT and MRI scans are investigation of choice in such cases, but they are sometimes inconclusive. It might be worth highlighting the good results of laparoscopic leiomyosarcoma lesion resection with a very good outcome.

This study aimed to develop a new auxiliary heterotopic partial liver transplantation (AHPLT) technique in minipigs using a model of liver cirrhosis. Based on our previous study, 14 minipigs were induced to cirrhosis by administration of carbon tetrachloride (CCl4) through intraperitoneal injection. All of the cirrhotic animals were utilized as recipients. The donor’s liver was placed on the recipient’s splenic bed, and the anastomosis was performed as follows: end-to-end anastomosis between the donor’s portal vein and the recipient’s splenic vein, end-to-side anastomosis between the donor’s suprahepatic vena cava and the recipient’s suprahepatic vena cava, and end-to-end anastomosis between the donor’s hepatic artery and the recipient’s splenic artery. The common bile duct of the donor was intubated and bile was collected with an extracorporeal bag. Vital signs, portal vein pressure (PVP), hepatic venous pressure (HVP) and portal vein pressure gradient (PVPG) were monitored throughout the transplantation. All 8 minipigs that developed liver cirrhosis were utilized to establish the new AHPLT; 7 cases survived. Following the surgical intervention, the PVP and PVPG of the recipients were lower than those prior to the operation (P<0.05), whereas the PVP and PVPG of the donors increased significantly compared to those of the normal animals (P<0.05). A new operative technique for AHPLT has been successfully described herein using a model of liver cirrhosis. PMID:22969983

Heterotopic ossification (HO) is the pathologic process of extraskeletal bone formation. Although the exact etiology remains unknown, inflammation appears to catalyze disease progression. The goal of this study is to determine the impact of the adaptive immune system on HO. HO was induced in 8-wk-old control C57BL/6 and immunocompromised Rag1tm1Mom (Rag1 KO) male mice deficient in B- and T-lymphocytes via combined Achilles tenotomy and burn injury. Microcomputed tomography quantified the extent of HO formation at the tenotomy site. Adipose-derived mesenchymal stem cells were harvested to evaluate osteogenic differentiation potential. Areas of developing HO demonstrated substantial enrichment of CD45 + leukocytes at 3 wk after injury. HO from Rag1 KO mice was substantially less mature with foci of cartilage and disorganized trabecular bone present 12 wk after injury. Rag1 KO mice formed 60% less bone compared to immunocompetent controls (4.67 ± 1.5 mm versus 7.76 ± 0.65 mm; P = 0.001). Tartrate-resistant acid phosphatase staining and immunofluorescent analysis of osteoprotegerin and nuclear factor kappa-light-chain-enhancer of activated B cells demonstrated no appreciable difference in osteoclast number or activation. Alizarin red staining in vitro demonstrated a significant decrease in osteogenic potential in immunocompromised mice compared to controls (29.1 ± 0.54 mm versus 12.1 ± 0.14 mm; P role for the adaptive immune system in the development of HO. In the absence of mature B- and T-lymphocytes, HO growth and development are attenuated. Furthermore, we demonstrate that mesenchymal populations from B- and T-cell deficient mice are inherently less osteogenic. This study identifies a potential therapeutic role for modulation of the adaptive immune system in the treatment of HO. Copyright © 2016 Elsevier Inc. All rights reserved.

Knowledge of risk factors is particularly useful to prevent or manage pelvic floor dysfunction but although a number of such factors have been proposed, results remain inconsistent. The purpose of this study was to evaluate the impact of aging on the incidence of posterior pelvic floor disorders in women with obstructed defecation syndrome evaluated using echodefecography. A total of 334 patients with obstructed defecation were evaluated using echodefecography in order to quantify posterior pelvic floor dysfunction (rectocele, intussusception, mucosal prolapse, paradoxical contraction or non-relaxation of the puborectalis muscle, and grade III enterocele/sigmoidocele). Patients were grouped according to the age (Group I = patients up to 50 years of age; Group II = patients over 50 years of age) to evaluate the isolated and associated incidence of dysfunctions. To evaluate the relationship between dysfunction and age-related changes, patients were also stratified into decades. Group I included 196 patients and Group II included 138. The incidence of significant rectocele, intussusception, rectocele associated with intussusception, rectocele associated with mucosal prolapse and 3 associated disorders was higher in Group II, whereas anismus was more prevalent in Group I. The incidence of significant rectocele, intussusception, mucosal prolapse and grade III enterocele/sigmoidocele was found to increase with age. Conversely, anismus decreased with age. Aging was shown to influence the incidence of posterior pelvic floor disorders (rectocele, intussusception, mucosa prolapse and enterocele/sigmoidocele), but not the incidence of anismus, in women with obstructed defecation syndrome.

Neurogenic heterotopic ossification (NHO) occurs as a complication of traumatic brain injury (TBI). Management of clinically significant NHO remains variable. Complications of mature NHO include limitation of mobility. The effect of the extracorporeal shock wave therapy (ESWT) on range of motion at hip and knee, and function in patients with TBI with chronic NHO was investigated. A series of single-case studies applying ESWT to chronic NHO at the hip or knee of 11 patients with TBI were undertaken at a rehabilitation hospital. Participants received four applications of high-energy EWST delivered to the affected hip or knee over a period of 8 weeks. Two-weekly follow- up assessments were carried out; final assessments were made 3 and 6 months post-intervention. Range of motion (ROM) and Functional Reach (FR) or Modified Functional Reach (MFR) were measured. Application of high-energy ESWT was associated with significant improvement in ROM (flexion) of the NHO-affected knee (Tau = 0.833, 95% CI 0.391-1.276, p = 0.002) and significant improvement of FR (Overall Tau 0.486, 95% CI 0.141-0.832, p = 0.006); no significant improvement in hip ROM or MFR. ESWT may improve mobility and balance of patients with TBI who have chronic NHO.

Imaging findings of morphology and regional cerebral blood flow in two patients suffering from epileptic seizures are presented. CT and MRI revealed heterotopic gray matter as a probable structural correlate, causing the seizure disorder. 99m Tc hexamethyl-propylenamine oxime (HM-PAO) SPECT demonstrated focally increased regional cerebral blood flow in both patients in the areas of their heterotopic lesions. Heterotopic and orthotopic gray matter seem to have similar features in terms of regional perfusion. A focally increased brain perfusion in interictal epileptic patients may indicate an underlying migration anomaly. (orig.)

Development of the Synarcual in the Elephant Sharks (Holocephali; Chondrichthyes: Implications for Vertebral Formation and Fusion.

Directory of Open Access Journals (Sweden)

Zerina Johanson

Full Text Available The synarcual is a structure incorporating multiple elements of two or more anterior vertebrae of the axial skeleton, forming immediately posterior to the cranium. It has been convergently acquired in the fossil group 'Placodermi', in Chondrichthyes (Holocephali, Batoidea, within the teleost group Syngnathiformes, and to varying degrees in a range of mammalian taxa. In addition, cervical vertebral fusion presents as an abnormal pathology in a variety of human disorders. Vertebrae develop from axially arranged somites, so that fusion could result from a failure of somite segmentation early in development, or from later heterotopic development of intervertebral bone or cartilage. Examination of early developmental stages indicates that in the Batoidea and the 'Placodermi', individual vertebrae developed normally and only later become incorporated into the synarcual, implying regular somite segmentation and vertebral development. Here we show that in the holocephalan Callorhinchus milii, uniform and regular vertebral segmentation also occurs, with anterior individual vertebra developing separately with subsequent fusion into a synarcual. Vertebral elements forming directly behind the synarcual continue to be incorporated into the synarcual through growth. This appears to be a common pattern through the Vertebrata. Research into human disorders, presenting as cervical fusion at birth, focuses on gene misexpression studies in humans and other mammals such as the mouse. However, in chondrichthyans, vertebral fusion represents the normal morphology, moreover, taxa such Leucoraja (Batoidea and Callorhinchus (Holocephali are increasingly used as laboratory animals, and the Callorhinchus genome has been sequenced and is available for study. Our observations on synarcual development in three major groups of early jawed vertebrates indicate that fusion involves heterotopic cartilage and perichondral bone/mineralised cartilage developing outside the regular

The aim of the present study was to assess inhibition of pain and somatosensory-evoked potentials (SEPs) by heterotopic noxious counter-stimulation (HNCS) and by selective attention in patients with chronic non-specific LBP. Seventeen patients and age/sex-matched controls were recruited (10 men, 7 women; mean age ± SD: 43.3 ± 10.4 and 42.7 ± 11.1, respectively). On average, patients with LBP reported pain duration of 7.6 ± 6.5 years, light to moderate disability (19.3 ± 5.7/100) and low clinical pain intensity (21.8 ± 1.5/100), while pain catastrophizing, state and trait anxiety and depressive symptoms were not significantly different between groups (all p's >0.05). HNCS and selective attention had differential inhibitory effects on pain and SEP, but no difference was observed between groups. Across both groups, HNCS decreased pain (p = 0.06) as well as the N100 and the N150 components of SEP (p's selective attention only decreased pain (p attention was directed toward the HNCS stimulus (pselective attention. Importantly, this experiment was carefully designed to control for non-specific effects associated with the repetition of the test stimulus and the effect of an innocuous counter-stimulation. It remains to be determined if these results hold for patients with severe LBP and psychological symptoms or whether symptom severity may be associated with pain inhibition deficits.

Riddiough, Georgina E; Bhatti, Imran; Ratliff, David A

2012-01-01

Meckel's diverticulum is a rare congenital abnormality arising due to the persistence of the vitelline duct in 1-3% of the population. Clinical presentation is varied and includes rectal bleeding, intestinal obstruction, diverticulitis and ulceration; therefore diagnosis can be difficult. We report a case of acute appendicitis complicated by persistent post operative small bowel obstruction. Further surgical examination of the bowel revealed an non-inflamed, inverted Meckel's diverticulum causing intussusception. Intestinal obstruction in patients with Meckel's diverticulum may be caused by volvulus, intussusception or incarceration of the diverticulum into a hernia. Obstruction secondary to intussusception is relatively uncommon and frequently leads to a confusing and complicated clinical picture. Consideration of Meckel's diverticulum although a rare diagnosis is imperative and this case raises the question "should surgeons routinely examine the bowel for Meckel's diverticulum at laparoscopy?"

Involvement of the Reck tumor suppressor protein in maternal and embryonic vascular remodeling in mice

Full Text Available Abstract Background Developmental angiogenesis proceeds through multiple morphogenetic events including sprouting, intussusception, and pruning. Mice lacking the membrane-anchored metalloproteinase regulator Reck die in utero around embryonic day 10.5 with halted vascular development; however, the mechanisms by which this phenotype arises remain unclear. Results We found that Reck is abundantly expressed in the cells associated with blood vessels undergoing angiogenesis or remodelling in the uteri of pregnant female mice. Some of the Reck-positive vessels show morphological features consistent with non-sprouting angiogenesis. Treatment with a vector expressing a small hairpin RNA against Reck severely disrupts the formation of blood vessels with a compact, round lumen. Similar defects were found in the vasculature of Reck-deficient or Reck conditional knockout embryos. Conclusions Our findings implicate Reck in vascular remodeling, possibly through non-sprouting angiogenesis, in both maternal and embyornic tissues.

Full Text Available PurposeHeterotopic ossification (HO occurs in the setting of persistent systemic inflammation. The identification of reliable biomarkers can serve as an early diagnostic tool for HO, especially given the current lack of effective treatment strategies. Although serum biomarkers have great utility, they can be inappropriate or ineffective in traumatic acute injuries and in patients with fibrodysplasia ossificans progressiva (FOP. Therefore, the goal of this study is to profile the cytokines associated with HO using a different non-invasive source of biomarkers.MethodsSerum and saliva were collected from a model of trauma-induced HO (tHO with hind limb Achilles’ tenotomy and dorsal burn injury at indicated time points (pre-injury, 48 h, 1 week, and 3 weeks post-injury and a genetic non-trauma HO model (Nfatc1-Cre/caAcvr1fl/wt. Samples were analyzed for 27 cytokines using the Bio-Plex assay. Histologic evaluation was performed in Nfatc1-Cre/caAcvr1fl/wt mice and at 48 h and 1 week post-injury in burn tenotomy mice. The mRNA expression levels of these cytokines at the tenotomy site were also quantified with quantitative real-time PCR. Pearson correlation coefficient was assessed between saliva and serum.ResultsLevels of TNF-α and IL-1β peaked at 48 h and 1 week post-injury in the burn/tenotomy cohort, and these values were significantly higher when compared with both uninjured (p < 0.01, p < 0.03 and burn-only mice (p < 0.01, p < 0.01. Immunofluorescence staining confirmed enhanced expression of IL-1β, TNF-α, and MCP-1 at the tenotomy site 48 h after injury. Monocyte chemoattractant protein-1 (MCP-1 and VEGF was detected in saliva showing elevated levels at 1 week post-injury in our tHO model when compared with both uninjured (p < 0.001, p < 0.01 and burn-only mice (p < 0.005, p < 0.01. The Pearson correlation between serum MCP-1 and salivary MCP-1 was statistically significant (r = 0

2017-10-24

Nasal glial heterotopia ("nasal glioma") and cutaneous heterotopic meningeal nodules ("primary cutaneous meningioma") are rare congenital lesions characterized by the presence of heterotopic mature cerebral tissues. Nasal glial heterotopia occurs predominantly in the nasal area and typically does not contain meningothelial elements, whereas heterotopic meningeal nodules occur predominantly on the scalp and do not contain glial elements. In this article, we report an unusual case of cutaneous heterotopia on the nose of an infant composed of both glial and meningothelial elements. The glial component was characterized by irregular islands of predominantly astrocytic cells, on a fibrillary background. The meningothelial component was characterized by bland ovoid cells with focal intranuclear inclusions forming whorled arrangements, with associated psammomatous calcification. To our knowledge, this is the first time such a lesion has been documented. It has also provided us with an opportunity to review the literature regarding heterotopic deposits of both glial and meningothelial tissues.

In 1999, the first rhesus-human reassortant rotavirus vaccine licensed in the United States was withdrawn within a year of its introduction after it was linked with intussusception at a rate of ∼1 excess case per 10,000 vaccinated infants. While clinical trials of 60,000-70,000 infants of each of the two current live oral rotavirus vaccines, RotaTeq (RV5) and Rotarix (RV1), did not find an association with intussusception, post-licensure studies have documented a risk in several high and middle income countries, at a rate of ∼1-6 excess cases per 100,000 vaccinated infants. However, considering this low risk against the large health benefits of vaccination that have been observed in many countries, including in countries with a documented vaccine-associated intussusception risk, policy makers and health organizations around the world continue to support the routine use of RV1 and RV5 in national infant immunization programs. Because the risk and benefit data from affluent settings may not be directly applicable to developing countries, further characterization of any associated intussusception risk following rotavirus vaccination as well as the health benefits of vaccination is desirable for low income settings.

Gallium-68 DOTA-peptide positron emission tomography/computed tomography ( 68 Ga-PET/CT) has emerged as a promising tool for the diagnosis and staging of gastro-entero-pancreatic neoplasms, thanks to its high sensitivity and specificity. Heterotopic pancreas, which is relatively rare, has never been reported as a possible cause of false positives of 68 Ga-PET/CT. We report on the first case of a heterotopic pancreas showing pathological uptake at 68 Ga-PET/CT, thus mimicking an intestinal neuroendocrine tumor. The present case suggests that heterotopic pancreas should be included among the possible causes of false positives at 68 Ga PET. Copyright © 2018 Elsevier Inc. All rights reserved.

Extensive studies revealed that the human corpus callosum (CC) plays a crucial role in providing large-scale bi-hemispheric integration of sensory, motor and cognitive processing, especially within the frontal lobe. However, the literature lacks of conclusive data regarding the structural macroscopic connectivity of the frontal CC. In this study, a novel microdissection approach was adopted, to expose the frontal fibers of CC from the dorsum to the lateral cortex in eight hemispheres and in one entire brain. Post-mortem results were then combined with data from advanced constrained spherical deconvolution in 130 healthy subjects. We demonstrated as the frontal CC provides dense inter-hemispheric connections. In particular, we found three types of fronto-callosal fibers, having a dorso-ventral organization. First, the dorso-medial CC fibers subserve homotopic connections between the homologous medial cortices of the superior frontal gyrus. Second, the ventro-lateral CC fibers subserve homotopic connections between lateral frontal cortices, including both the middle frontal gyrus and the inferior frontal gyrus, as well as heterotopic connections between the medial and lateral frontal cortices. Third, the ventro-striatal CC fibers connect the medial and lateral frontal cortices with the contralateral putamen and caudate nucleus. We also highlighted an intricate crossing of CC fibers with the main association pathways terminating in the lateral regions of the frontal lobes. This combined approach of ex vivo microdissection and in vivo diffusion tractography allowed demonstrating a previously unappreciated three-dimensional architecture of the anterior frontal CC, thus clarifying the functional role of the CC in mediating the inter-hemispheric connectivity.

The new Radiation Oncology Department at the Heidelberg Repatriation Hospital in Melbourne, Australia commenced operation in June 1992. As part of quality control the Philips SL-15 linear accelerator was fitted with the Philips SRI-100 Real Time Portal Imaging Device (RTPID), the first such apparatus in Australia. One of its major advantages over older systems is its ability to provide a permanent hard copy of the image of the field treated. The computer image can be immediately manipulated and enhanced on the screen (with respect to such qualities as brightness and contrast) prior to the printing of the hard copy. This is a significant improvement over the more cumbersome older port films that required developing time, without any pre-assessment of the image quality. The utility of the Philips SRI-100 RTPID is demonstrated in the case of a patient irradiated soon after total hip replacement, as prophylaxis against heterotopic bone formation (HBF). The rapidity and quality of image production is a major advantage in these patients where post operative pain may result in positional change between film exposure and image production. Extremely accurate shielding block position is essential to shield the prosthesis(and allow bone ingrowth for fixation) whilst avoiding inadvertent shielding of the areas at risk for HBF. A review of the literature on this topic is provided. 14 refs., 4 figs

We previously generated viable heterotopic bone in living animals and found that 3 months of intrinsic vascularization improved bone formation and matrix degeneration. In this study, we varied the pre-vascularization time to determine its effects on the kinetics of bone formation and ceramic degradation. Two 25-mm-long cylindrical β-tricalcium phosphate scaffolds were filled intraoperatively with autogenous iliac crest bone marrow and implanted in the latissimus dorsi muscle in six sheep. To examine the effect of axial perfusion, one scaffold was surgically implanted with (group C) or without (group D) a central vascular bundle. All animals were sacrificed 6 months postoperatively and histomorphometric measurements were compared to previous results. All implanted scaffolds exhibited ectopic bone growth. However, bone growth was not significantly different between the 3-month (group A, 0.191±0.097 vs. group C, 0.237±0.075; P=0.345) and 6-month (group B, 0.303±0.105 vs. group D, 0.365±0.258; P=0.549) pre-vascularization durations, regardless of vessel supply; early differences between surgically and extrinsically vascularized constructs disappeared after 6 months. Here, we describe a reliable procedure for generating ectopic bone in vivo. A 3-month pre-vascularization duration appears sufficient and ceramic degradation proceeds in accordance with bone generation, supporting the hypothesis of cell-mediated resorption.

Full Text Available Abstract Introduction Conservative treatment of a heterotopic cervical pregnancy was performed with a modification of the fixation of a Foley catheter at the level of the external cervical os, followed by the ligature of the descending cervical branches of the uterine arteries and systemic methotrexate application. Case presentation A 34-year-old Caucasian woman was diagnosed with double gestation after 6 weeks of in vitro fertilization treatment. A gynecological examination and color Doppler ultrasound scan revealed intra-uterine and cervical gestational sacs both containing live fetuses. A Foley catheter balloon was inserted into the cervical canal, inflated and fixed by a cerclage suture at the level of the external cervical os, followed by ligation of the descending cervical branches of the uterine arteries. Systemic methotrexate was applied. Three days after removal of the Foley catheter, an evacuation of the intra-uterine gestational sac was performed. Hemorrhage from the implantation site was controlled immediately and a pregnancy termination was successfully performed. The procedure was uneventful and our patient was discharged with a preserved uterus. Conclusions Conservative treatment of cervical pregnancy using a Foley catheter balloon is more efficacious if the Foley catheter balloon is attached in the correct position with a cerclage suture at the level of the external os, followed by ligation of the descending cervical branches of the uterine arteries, thereby exerting maximal pressure on the bleeding vessels.

Aim Heterotopic gastric mucosa is a well-known congenital anomaly in Meckel's diverticula and duplication cysts. Solitary heterotopic gastric mucosa in the rectum is a rare and frequently overlooked abnormality. Starting from a patient history, the literature is searched and all cases reported over the past 20 years are reviewed and compared to a summary of the older cases. Differences between adult and childhood presentation are outlined and our patient is compared with prior reported cases. Case A 3-year-old girl presented with recurrent rectal blood loss caused by heterotopic gastric mucosa without duplication cyst. She was endoscopically treated with two-stage endoscopic surgical dissection (ESD). Up to now, rectal heterotopic gastric mucosa has been reported in 34 adults and 24 children, including this patient. There is an overall male dominance (69%). Presenting complaints in children were recurrent fresh blood loss per anum (96%), pain (46%), perineal ulcers (25%), diarrhoea (8%) and one patient had an ano-cutaneous fistula. Endoscopy revealed a mucosal elevation with a slightly different aspect (33%), a polyp (42%) and a solitary ulcer (25%). Endoscopy in adults reveals more frequently polyps compared to children. Treatment in childhood is mainly surgical where adults are more frequently treated with endoscopic techniques. Conclusion In a child with recurrent rectal bleeding in good general health, it is important to withhold heterotopic gastric mucosa in the differential diagnosis and take sufficient biopsies during endoscopy. © Acta Gastro-Enterologica Belgica.

A New Animal Model for Investigation of Mechanical Unloading in Hypertrophic and Failing Hearts: Combination of Transverse Aortic Constriction and Heterotopic Heart Transplantation.

Andreas Schaefer

Full Text Available Previous small animal models for simulation of mechanical unloading are solely performed in healthy or infarcted hearts, not representing the pathophysiology of hypertrophic and dilated hearts emerging in heart failure patients. In this article, we present a new and economic small animal model to investigate mechanical unloading in hypertrophic and failing hearts: the combination of transverse aortic constriction (TAC and heterotopic heart transplantation (hHTx in rats.To induce cardiac hypertrophy and failure in rat hearts, three-week old rats underwent TAC procedure. Three and six weeks after TAC, hHTx with hypertrophic and failing hearts in Lewis rats was performed to induce mechanical unloading. After 14 days of mechanical unloading animals were euthanatized and grafts were explanted for further investigations.50 TAC procedures were performed with a survival of 92% (46/50. When compared to healthy rats left ventricular surface decreased to 5.8±1.0 mm² (vs. 9.6± 2.4 mm² (p = 0.001 after three weeks with a fractional shortening (FS of 23.7± 4.3% vs. 28.2± 1.5% (p = 0.01. Six weeks later, systolic function decreased to 17.1± 3.2% vs. 28.2± 1.5% (p = 0.0001 and left ventricular inner surface increased to 19.9±1.1 mm² (p = 0.0001. Intraoperative graft survival during hHTx was 80% with 46 performed procedures (37/46. All transplanted organs survived two weeks of mechanical unloading.Combination of TAC and hHTx in rats offers an economic and reproducible small animal model enabling serial examination of mechanical unloading in a truly hypertrophic and failing heart, representing the typical pressure overloaded and dilated LV, occurring in patients with moderate to severe heart failure.

A case of inflammatory fibroid polyp of the sigmoid colon is presented. This is the eight case of this type of polyp in the colon and, to the best of our knowledge, the first one involving the sigmoid and producing intussusception. Symptomatology of the inflamed fibroid polyp in this part of the gut closely simulates gastrointestinal malignancy. The treatment is surgical excision of the polyp, or colonoscopic resection when it is possible. Intraoperative colonoscopy helps the surgeon to localize the lesion and to role out the existence of other lesions.

With the advent of cyclosporin A, accelerated coronary arteriosclerosis has become the major impediment to the long-term survival of heart transplant recipients. Due to epidemiologic reports suggesting a salutary effect of fish oil, the dose response of fish oil on graft coronary arteriosclerosis in a rabbit heterotopic cardiac allograft model was assessed using safflower oil as a caloric control. Seven groups of New Zealand White rabbits (n = 10/group) received heterotropic heart transplants from Dutch-Belted donors and were immunosuppressed with low-dose cyclosporin A (7.5 mg/kg/day). Group 1 animals were fed a normal diet and served as control. Group 2, 3, and 4 animals received a daily supplement of low- (0.25 mL/kg/day), medium- (0.75 mL/kg/day), and high- (1.5 mL/kg/day) dose fish oil (116 mg n-3 polyunsaturated fatty acid/mL), respectively. Group 5, 6, and 7 animals were supplemented with equivalent dose of safflower oil (i.e., 0.25, 0.75, and 1.5 mL/kg/day). Oil-supplemented rabbits were pretreated for 3 weeks before transplantation and maintained on the same diet for 6 weeks after operation. The extent of graft coronary arteriosclerosis was quantified using computer-assisted, morphometric planimetry. When the animals were killed, cyclosporin A was associated with elevated plasma total cholesterol and triglyceride levels in the control group. While safflower oil prevented the increase in plasma lipids at all dosages, fish oil ameliorated the cyclosporin-induced increase in total cholesterol only with high doses. Compared to control animals, there was a trend for more graft vessel disease with increasing fish oil dose, as assessed by mean luminal occlusion and intimal thickness. A steeper trend was observed for increasing doses of safflower oil; compared to the high-dose safflower oil group, animals supplemented with low-dose safflower oil had less mean luminal occlusion (16.3% +/- 5.9% versus 41.4% +/- 7.6%, p less than 0.017) and intimal thickness (7

Full Text Available Abstract Introduction Neuroglial heterotopia, heterotopic brain tissue, or differentiated neural tissue outside the cranial vault is uncommon, and these anomalies most commonly occur in the nasal cavity. Case presentation We report a case of rare pure cystic heterotopic brain tissue in a two-month-old Caucasian baby girl that presented as a large cystic neck mass and was confused with a cystic hygroma. Her mother reported a progressive increase in the size of this swelling and mild respiratory difficulty when the girl was sleeping. A computed tomography scan of the brain and neck showed a large heterogeneous mass extending from the base of the skull to the left submandibular region; a cystic component was also noted. Our patient under went total excision of the cystic mass and prevention of airway obstruction by a left submandibular approach. The final gross pathology diagnosis was heterotopic brain tissue. Conclusions Pure cystic neck heterotopic brain tissue lesions are very uncommon, and a preoperative diagnosis of this lesion is difficult. Brain heterotopia is a rare, benign condition that should be considered in the differential diagnosis of the neonatal head and neck mass.

Background: The effectiveness of pre- or postoperative radiotherapy for prevention of heterotopic ossification (HO) following total hip replacement (THR) has already been demonstrated in the past. Thereby, in most studies using preoperative radiotherapy patients were irradiated < 6 h before surgery. The purpose of this prospective study was to analyze the effectiveness of preoperative irradiation on the evening before surgery and to identify risk factors for HO in a homogeneous collective of patients. Patients and Methods: From July 1997 to July 2001, 416 patients (462 hips; 235 males, 227 females) received preoperative radiotherapy of the hip on the evening before surgery with a 7-Gy single fraction. The patients' median age was 67.1 years. The most frequent indication for radiotherapy was hypertrophic osteoarthritis (383 hips, 82.9%). Treatment results were assessed by comparison of pre- and postoperative hip X-rays (immediately and 6 months after surgery). The analysis of radiographs was performed according to the Brooker score. Results: The overall incidence of HO was 18.1% (n = 84), Brooker score 1 12.3% (n = 57), score 2 3.9% (n = 18), score 3 1.5% (n = 7), and score 4 0.4% (n = 2). Sex, body height, hypertrophic osteoarthritis of higher degree, size of the femoral component of the prosthesis, previous ipsi- or contralateral HO, and short course of nonsteroidal anti-inflammatory drug (diclofenac) therapy significantly influenced the HO rate in univariate analysis. In multivariate analysis, an interdependence of prosthesis size, sex and patient's height was found. From these three variables, only prosthesis size was statistically significant in multivariate analysis. The cumulative dose of diclofenac ({<=} 300 mg or > 300 mg) within the first 7 postoperative days and previous ipsi- or contralateral HO influenced the incidence of HO in multivariate analysis. Conclusion: Preoperative radiotherapy on the evening before surgery is an effective treatment

Cystic duplications of the biliary tract are rare anomalies, easily mistaken for choledochal cysts. Surgical drainage is the preferred therapy for choledochal cyst, but cystic duplication necessitates surgical excision as duplications may contain heterotopic gastric mucosa leading to peptic ulceration of the biliary tract. We report a case of biliary tract duplication cyst containing heterotopic alimentary mucosa which had initially been diagnosed and surgically treated as a choledochal cyst.

Differential inhibitory effect on human nociceptive skin senses induced by local stimulation of thin cutaneous fibers.

Science.gov (United States)

Nilsson, H J; Schouenborg, J

1999-03-01

It is known that stimulation of thin cutaneous nerve fibers can induce long lasting analgesia through both supraspinal and segmental mechanisms, the latter often exhibiting restricted receptive fields. On this basis, we recently developed a new method, termed cutaneous field stimulation (CFS), for localized stimulation of A delta and C fibers in the superficial part of the skin. In the present study, we have evaluated the effects of CFS on non-nociceptive and nociceptive skin senses. We compared the effects of CFS with those of conventional transcutaneous electrical nerve stimulation (TENS), known to preferentially activate coarse myelinated fibers. A battery of sensory tests were made on the right volar forearm of 20 healthy subjects. CFS (16 electrodes, 4 Hz per electrode, 1 ms, up to 0.8 mA) and TENS (100 Hz, 0.2 ms, up to 26 mA) applied either on the right volar forearm (homotopically), or on the lower right leg (heterotopically) were used as conditioning stimulation for 25 min. The tactile threshold was not affected by either homo- or heterotopical CFS or TENS. The mean thresholds for detecting warming or cooling of the skin were increased by 0.4-0.9 degrees C after homo- but not heterotopical CFS and TENS. Regarding nociceptive skin senses, homo- but not heterotopical CFS, markedly reduced CO2-laser evoked A delta- and C fiber mediated heat pain to 75 and 48% of control, respectively, and mechanically evoked pain to 73% of control. Fabric evoked prickle, was not affected by CFS. Neither homo- nor heterotopical TENS induced any marked analgesic effects. It is concluded that different qualities of nociception can be differentially controlled by CFS.

To evaluate the CT findings of small bowel metastases from primary lung cancer. Of the 1468 patients with primary lung cancer between 1990 and 2000, 13 patients who had metastasis to the small intestine were collected. Of these 13 patients, nine who underwent CT scan were included for analysis. The pathologic diagnoses of primary lung cancer in these nine patients were squamous cell carcinoma in six, adenocarcinoma in two, and large cell carcinoma in one. CT scans were analyzed with regard to the site and patterns (intraluminal mass/bowel wall thickening/bowel implants) of metastatic masses, and the presence or absence of complication such as intussusception, obstruction, or perforation of the small bowel. The medical records of the patients were also reviewed retrospectively for evaluation of presenting abdominal symptom and time interval of metastases from initial diagnosis of lung cancer. Metastatic lesions were distributed throughout the small intestine: the duodenum in five, the jejunum in four, the ileum in six, and both jejunum and ileum in one patient. The size of metastatic masses of small bowel ranged from 1.3 cm to 5.0 cm (mean size, 2.6 cm) On CT, the small bowel was involved with intraluminal masses (mean size, 3.4 cm) in eight patients, diffuse wall thickening (mean thickness, 1.6 cm) in five, and bowel implants (mean size, 2.2 cm) in two. Complications occurred in seven patients, including intussusceptions without obstruction in two patients and with obstruction in two, obstruction without intussusceptions in two, and bowel perforation in one. Of 9 patients, 6 had at least one symptom referable to the small bowel including abdominal pain in 4, anemia in 3, vomiting in 1, and jaundice in 1. Lung cancer and small bowel lesions were detected simultaneously in four patients and the time interval of metastases from initial diagnosis of lung cancer ranged from 10 days to 30 months (median interval, 54 days) in patients.

Defecography is the gold standard for assessing functional anorectal disorders but is limited by the need for a specific radiologic environment, exposure of patients to radiation, and inability to show all anatomic structures involved in defecation. Echodefecography is a 3-dimensional dynamic ultrasound technique developed to overcome these limitations. This study was designed to validate the effectiveness of echodefecography compared with defecography in the assessment of anorectal dysfunctions related to obstructed defecation. Multicenter, prospective observational study. Women with symptoms of obstructed defecation. Six centers for colorectal surgery (3 in Brazil, 1 in Texas, 1 in Florida, and 1 in Venezuela). Defecography was performed after inserting 150 mL of barium paste in the rectum. Echodefecography was performed with a 2050 endoprobe through 3 automatic scans. The κ statistic was used to assess agreement between echodefecography and defecography in the evaluation of rectocele, intussusception, anismus, and grade III enterocele. Eighty-six women were evaluated: median Wexner constipation score, 13.4 (range, 6-23); median age, 53.4 (range, 26-77) years. Rectocele was identified with substantial agreement between the 2 methods (defecography, 80 patients; echodefecography, 76 patients; κ = 0.61; 95% CI = 0.48-0.73). The 2 techniques demonstrated identical findings in 6 patients without rectocele, and in 9 patients with grade I, 29 with grade II, and 19 patients with grade III rectoceles. Defecography identified rectal intussusception in 42 patients, with echodefecography identifying 37 of these cases, plus 4 additional cases, yielding substantial agreement (κ = 0.79; 95% CI = 0.57-1.0). Intussusception was associated with rectocele in 28 patients for both methods (κ = 0.62; 95% CI = 0.41-0.83). There was substantial agreement for anismus (κ = 0.61; 95% CI = 0.40-0.81) and for rectocele combined with anismus (κ = 0.61; 95% CI = 0.40-0.82). Agreement for

Full Text Available BACKGROUND: The preoperative Heterotopic Ossification (HO extent is usually one of the main used criteria to predict the recurrence before excision. Brooker et al built a radiologic scale to assess this pre operative extent around the hip. The aim of this study is to investigate the relationship between the recurrence risk after hip HO excision in Traumatic Brain Injury (TBI and Spinal Cord Injury (SCI patients and the preoperative extent of HO. METHODOLOGY/PRINCIPAL FINDINGS: A case control study including TBI or SCI patients following surgery for troublesome hip HO with (case, n = 19 or without (control, n = 76 recurrence. Matching criteria were: sex, pathology (SCI or TBI and age at the time of surgery (+/-4.5 years. For each etiology (TBI and SCI, the residual cognitive and functional status (Garland classification, the preoperative extent (Brooker status, the modified radiological and functional status (GCG-BD classification, HO localization, side, mean age at the CNS damage, mean delay for the first HO surgery, and for the case series, the mean operative delay for recurrence after the first surgical intervention were noted. CONCLUSIONS/SIGNIFICANCE: The median delay for first HO surgery was 38.6 months (range 4.5 to 414.5; for the case subgroup and 17.6 months (range 5.7 to 339.6 for the control group. No significant link was found between recurrence and operative delay (p = 0.51; the location around the joint (0.07; the Brooker (p = 0.52 or GCG-BD status (p = 0.79. Including all the matching factors, no significant relationship was found between the recurrence HO risk and the preoperative extent of troublesome hip HO using Brooker status (OR = 1.56(95% CI: 0.47-5.19 or GCG-BD status (OR class 3 versus 2 = 0.67(95% CI: 0.11-4.24 and OR class 4 versus 2 = 0.79(95%CI: 0.09-6.91. Until the pathophysiology of HO development is understood, it will be difficult to create tools which can predict HO recurrence.

IntroductionTwo vaccines available for protection against rotavirus gastroenteritis (RVGE), Rotarix and RotaTeq, have contributed to a large decrease in the incidence of paediatric diarrhoea in countries where they have been used. However, they have also led to a small increase in the risk of intussusception. Methods: We compare the number of prevented hospitalisations for RVGE to the number of vaccine-induced hospitalised intussusceptions in France. Results: With 9.5% coverage (French 2015 estimation), vaccination was estimated to prevent, annually, a median of 1,074 hospitalisations (2.5th and 97.5th percentiles (2.5th-97.5th): 810-1,378) and 1.4 deaths (2.5th-97.5th: 1.2-1.6) from RVGE. It was also estimated to cause, annually, 5.0 hospitalisations (2.5th-97.5th: 3.2-7.7) and 0.005 deaths (2.5th-97.5th: 0.001-0.015) from intussusception. The benefit-risk ratio is therefore 214 (2.5th-97.5th: 128-362) for hospitalisations and 273 (2.5th-97.5th: 89-1,228) for deaths. Under a hypothetical 92% coverage, rotavirus vaccination with Rotarix would avoid 10,459 (2.5th-97.5th: 7,702-13,498) hospitalisations for RVGE and induce 47.0 (2.5th-97.5th: 25.1-81.4) hospitalisations for intussusception annually, thereby preventing 13.7 (2.5th-97.5th: 11.1-15.2) deaths and inducing 0.05 (2.5th-97.5th: 0.01-0.15) deaths. Conclusion: The benefit-risk ratio in France is similar to that of other European countries.

Obstructed defaecation syndrome (ODS) represents a very common clinical problem. The aim of the this prospective multicenter study was to evaluate the efficacy and safety of stapler trans-anal rectal resection (STARR) performed by a new dedicated device, CCS-30 Contour Transtar, in patients with ODS caused by rectal intussusception (RI) and/or rectocele (RE). All the patients who underwent STARR for ODS caused by RI and/or RE at Colorectal Surgery Units of S. Stefano Hospital, Naples, Gepos Hospital, Telese, Benevento and S. Maria della Pietà Hospital, Casoria, Naples, Italy were prospectively introduced into a database. Preoperatively, all the patients underwent anorectal manometry and cinedefecography. The grade of ODS was assessed using a dedicated obstructed defaecation syndrome score (ODS-S). All the patients with a ODS-S >or=12 and RI and/or RE were enrolled. Patients were followed up clinically at 6 months. Thirty patients, 28 (93.3%) women, mean age 56.6+/-12.7 years, underwent STARR, by Transtar, between February and October 2006. Preoperatively, ODS-S was 15.8+/-2.4. RI was present in 26 (89.6%) and RE (34.4+/-15.2 mm) in 27 (93.1%) patients. No major postoperative complications occurred. The length of hospital stay was 2.5+/-0.6 days. At 6-month follow-up, ODS-S was 5.0+/-2.3 (P<0.001). Successful outcome was achieved in 25 (86.2%) patients. STARR, performed by the new dedicated device, CCS-30 Contour Transtar, seems to be an effective and safe procedure to treat ODS caused by RE and/or RI. A longer follow-up and a larger number of patients is needed to confirm these results.

Diagnostic imaging of digestive tract involvement in cystic fibrosis. Part 2: pancreatic and gastrointestinal disease

Cystic fibrosis (CF) is the most common fatal, autosomal recessive disease among the white population. Although recurrent pulmonary infections and pulmonary insufficiency are the major causes of morbidity and mortality, gastrointestinal symptoms generally present earlier and may suggest the diagnosis in the newborn or even prior to birth. The changes are attributed to the secretion of an abnormally thick mucous into the intestinal lumen, leading to the hallmark of diseases of the digestive tract: obstruction. This can be detected at birth in the form of mecanium ileus, ileal atresia, mecanium peritonitis and mecomiun plug, or present later on in childhood and adolescence as distal bowel obstruction syndrome or fibrosing colonopathy. This thick mucous can also trigger intussusception or acute appendicitis. Pancreatic insufficiency or pancreatic enzyme replacement therapy is the direct cause of most of these disorders. Plain radiography is of the utmost utility in assessing the digestive tract in CF. When the disease is detected in a newborn, the recommended approach is to perform plain abdominal X-ray, followed by barium enema, always accompanied by ultrasound. In older children and adolescents, enema and ultrasound are usually sufficient, although computed tomography and magnetic resonance may sometimes be necessary. (Author) 52 refs

Myositis ossificans is a benign, self-limiting and non-neoplastic development of heterotopic bone in skeletal muscle following trauma. Although myositis ossificans can occur anywhere in the body, psoas muscle involvement is very rare. To the best of our knowledge, CT and MR imaging findings of myositis ossificans in the psoas muscle secondary to lumbar spine fracture have not been reported in the radiological literature. In this article, we describe the CT and MR imaging findings of myositis ossificans of the psoas muscle after lumbar spine fracture in a 64-year-old man, and conduct a review of the relevant literature

Eight hundred defecograms using a specially designed seat attached to the fluoroscopic table showed rectal intussusception in 78.3%, rectocele in 53.0%, enterocele in 19.7%, spastic pelvic floor in 15.1%, and normal findings in 2.1%. Pneumocolon in conjunction with defecograms showed whether enteroceles contained colon or small intestine. Because of the high incidence of enteroceles in descending pelvic floor syndrome, defecography is essential prior to pelvic surgery. In 20 patients, solitary rectal ulcer syndrome was diagnosed by means of same-day defecography, pneumocolon, and biopsy. Eighty percent showed intussusception. In two cases, the defeco gram traced the gastrointestinal (GI) bleeding to a rectal ulcer, indicating its usefulness in diagnostic workup for GI bleeding

Deformities of the cervical spine are uncommon in the coronal plane. In this report, a unique case of a 31-year-old male with a fixed, 30° left coronal deformity due to heterotopic ossification 3 years status post poly-trauma was treated with an asymmetric C7 pedicle subtraction osteotomy (PSO). Case report. Pre-operatively, the patient had a fixed 45-degree left tilt of his neck and radiographs demonstrated a rigid 30° scoliosis, 7 cm coronal imbalance, and 4 cm negative sagittal balance, diffuse bridging bone between the spinous processes and the facet joints of C5 to T1 bilaterally. An asymmetric C7 PSO with C2-T3 posterior spinal fusion was completed without complication. There was residual 9° coronal deformity, 2.9 cm left coronal imbalance, and 2.3 cm sagittal imbalance. He had a marked improvement in his function, as assessed by the SF-36 physical component score (pre-op 31.1; post-op 44.7) and mental component score (pre-op 46.0; post-op 66.8). Post-operatively, neck disability index scores also improved (pre-op 38; post-op 16). Although the patient passed away from a drug overdose 14 months post-operatively, he did not report neck pain, he had not sought evaluation from another physician for his neck, and he had not undergone a subsequent neck operation before his passing. In this one patient, an asymmetric C7 PSO was performed safely. While it was effective in addressing a fixed cervical coronal imbalance, its efficacy and safety profile should be confirmed in larger cohorts.

haematopoietic bone marrow that forms by day 15 in heterotopic rectus abdominis sites. Synergistic binary applications also induce the morphogenesis of rudimentary embryonic growth plates indicating that the "memory" of developmental events in embryo can be redeployed postnatally by the application of morphogen combinations. Synergistic binary applications or single relatively high doses of hTGF-β3 have shown that hTGF-β3 induces bone by expressing a variety of inductive morphogenetic proteins that result in the rapid induction of bone formation. Tissue induction thus invocated singly by hTGF-β3 recapitulates the synergistic induction of bone formation by binary applications of hTGF-β1 and -β3 isoforms with hOP-1. Both synergistic strategies result in the rapid induction and expansion of the transformed mesenchymal tissue into large corticalized heterotopic ossicles with osteoblast-like cell differentiation at the periphery of the implanted reconstituted specimens with "tissue transfiguration" in vivo. Molecularly, the rapid induction of bone formation by binary applications of hOP-1 and hTGF-β3 or by hTGF-β3 applied singly resides in the up-regulation of selected genes involved in tissue induction and morphogenesis, Osteocalcin, RUNX-2, OP-1, TGF-β1 and -β3 with however the noted lack of TGF-β2 up-regulation.

Defacography is a technique of examining the rectum and anal canal by using fluoroscopy during detection. This study was done to determine the range of normal findings of defecography in young asymptomatic Korean volunteers. Twenty nine asymptomatic young volunteers underwent defecography. Anorectal angle, perineal descent, length and width of anal, rectocele, rectal intussusception and incontinence were evaluated. The range of anorectal angle was 82 .deg- 149 .deg in resting state, compared to the 63 .deg-116 .deg in squeezing state, and 95 .deg- 116 .deg in straining state respectively. The pelvic floor in straining state descended on average of 1.62 cm from the inferior margin of ischial tuberosity that its broad range of position from-5.2 cm to 0.8 cm implies a wide variation of anorectal angle and perineal descent. Mild degree of rectocele with less than 2 cm of depth was found in 12 out of 29 cases. Rectal intussusception was noted in six and rectal incontinence was seen in one case. Formation of rectocele and intussusception during defecation was common in asymptomatic young volunteers. The wide range of defacographic measurements warrants the necessity of other complementary studies on anorectal function to improve the diagnostic accuracy. The interpretation of defecographic measurement should therefore be made with caution and should not be used as the sole criteria for selection of treatment modality

Approximately 0.04% of the general population will present with a complication related to Meckel diverticulum. The classic teaching is that symptomatic children with Meckel diverticulum present with painless rectal bleeding and are evaluated with a radionuclide scan. Our subjective experience is that we see children with Meckel diverticulum who present with abdominal pain and are evaluated by CT. We reviewed the findings on CT in children with pathologically proven Meckel diverticulum to identify characteristic patterns of presentation. Databases were searched (2004-2008) for all children who had a pathologic diagnosis of Meckel diverticulum and a CT scan performed prior to surgery. Demographics, pathology, and CT features were reviewed. CT features reviewed included: soft-tissue stranding, abnormal calcifications, bowel obstruction, free air, free peritoneal fluid, cystic mass, intussusception, obvious lead point, location, and whether a normal appendix was identified. The frequency of Meckel diverticulum encountered on CT scans was compared to that found during the same period of time on technetium pertechnetate studies. The review identified 16 subjects (mean age 9.5 years, M:F 9:7). CT findings included: soft-tissue stranding in nine (56%), small-bowel obstruction (SBO) in nine (56%), intussusception in three (19%), free fluid in ten (63%), cystic mass in four (25%), calcification in none (0%), free air in one (6%), and no abnormalities in two (13%). A normal appendix was identified in only five children (31%). There were three basic patterns of presentation of abnormalities: SBO only in five, intussusception with SBO in three, or cystic mass with inflammatory stranding in four (one with SBO). Also, 2.3 times more Meckel diverticulum was encountered on CT than on technetium pertechnetate studies. Meckel diverticulum is currently more commonly encountered in children on CT performed for abdominal pain than on technetium pertechnetate studies. There are three

Viral infection are an extremely serious in allogeneic bone transplantations. While it is essential to kill viruses such as HIV in allogeneic bone graft, the osteoinductive activity must be preserved. Heat treatment of allogeneic bone graft at 60 degree C for 10 hours is effective in killing viruses such as HIV, but it is unclear to what extent the activity of human bone morphogenetic protein (hBMP) is preserved. In this experiment crude hBMP was extracted from both heated and non-heated human bones which were decalcified by the Urist method. Gelatin capsules containing 5mg of crude hBMP were transplanted into the thigh muscles of 5 week old mice. Human bone samples heated in a water bath at 60 degree C for 10 hours and non-heated samples were each transplanted into 5 mice. At 20 days after transplantation, the heterotopic bone formation was compared by evaluation of X-ray and histologicic analysis. X-rays showed heterotopic bone formation in both heated and non-heated samples. Further, histologic analysis showed that peripheral osteoid tissue had developed into laminar bone formation and interlaminar bone marrow was observed. Heterotopic bone formation was induced by crude hBMP from heated bones in a similar way to crude hBMP from non-heated bones observed in X-ray. There was no significant difference in histologic analysis. The crude hBMP, extracted from bones which were heat-treated at 60 degree C for 10 hours induced heterotopic bone formation similar to that in non-heated bone observed by X-ray and histologic analysis at 20 days after transplantation. This demostrates that the heat-treated bone preserved osteoinduction

Regional blood flow in experimental myositis ossificans

1983-01-01

In a recent model for heterotopic bone formation, muscular oedema, swelling and necrosis is seen in the quadriceps muscle of rabbit hind limbs immobilized for at least 2 weeks when, from the second week, the immobilized limb is subjected to dayly forcible mobilization lasting about 5 min. According to this model, heterotopic calcification develops gradually from the second week of forcible mobilization and is located in the vastus intermedius region. Between the fourth and fifth week of immobilization and forcible mobilization, heterotopic bone formation is seen in virtually all cases. The histological findings are similar to those in human ectopic bone formation. In the present investigation the labelled microsphere technique was used to study the regional blood flow effects in the early development of myositis ossificans with this model. The results are quite different from those reported by other investigators on immobilization alone and point to a causal relation between regional blood flow and forcible mobilization of the immobilized rabbit hind limp. Prostaglandins as mediators between the traumatic inflammation, a part of the circulatory effects observed and the induction of a new bone is suggested. (author)

Specific alteration of rhythm in temperature-stressed rats possess features of abdominal pain in IBS patients

Full Text Available It is known that specific alteration of rhythm in temperature (SART stress produces somatic pain. However, it remains to be investigated whether SART stress induces visceral pain. In this study, we investigated the visceral hypersensitivity in the SART stress model by pharmacological tools and heterotopical nociception. Four-week-old Sprague–Dawley rats were exposed to repeated cold stress. Visceral pain was measured by visceromotor response to colorectal distension, and the effects of alosetron and duloxetine on visceral pain were investigated in SART rats. Heterotopical nociception was given by capsaicin injection into the left forepaw to induce diffuse noxious inhibitory controls (DNIC. SART stress induced visceral hypersensitivity that was sustained at minimum for one week. In pharmacological analysis, alosetron and duloxetine improved SART stress-induced visceral hypersensitivity. Heterotopical nociception induced DNIC in normal conditions, but was disrupted in SART rats. On the other hand, RMCP-II mRNA in distal colon was not affected by SART stress. In conclusion, SART rats exhibit several features of visceral pain in IBS, and may be a useful model for investigating the central modification of pain control in IBS.

Inflammatory fibroid polyps (IFPs) are rarely found in the gastrointestinal tract. The majority of IFPs are sessile-pedunculated or pedunculated polypoid lesions, whereas a polyp presenting like a Borrmann type II lesion is extremely unusual. This report describes the case of a 74-year-old man with a history of intussusception, in whom a preoperative diagnosis of a cecal tumor of the ileocecal valve was made. A laparotomy subsequently revealed a lesion similar to a Borrmann type II tumor located 15 cm above the ileocecal valve, but not at the valve. The lesion was diagnosed as an IFP which had been caused by repeated colostomy irrigation. The aim of the present report is to draw attention to this entity, which should be included in the differential diagnosis of intussusception and small bowel obstruction.

2011-01-01

Full Text Available Congenital diaphragmatic hernia is a common congenital anomaly of uncertain etiology. Its association with multiple congenital anomalies in various organs is well recognized and antenatal radiological evidence of congenital diaphragmatic hernia warrants thorough evaluation to detect other anomalies, some of which can be life threatening. Rarely, heterotopic hepatic tissue is identified in the hernia, a rare pathological finding, exhibiting more than one macroscopic and microscopic characteristics, and always associated with cardiac congenital anomalies. Herein, we report a case of left-sided microscopic heterotopic hepatic tissue in a congenital diaphragmatic hernia in an infant with multiple cardiac congenital anomalies, but with preserved pericardium.

We studied the neuropathologic features of a patient with Coffin-Siris syndrome. Two previously reported cases showed Dandy-Walker (D-W) malformations. In the present case there was no evidence of D-W malformation; instead there were hindbrain abnormalities of inferior and medial accessory olives, large arcuate nuclei, heterotopic olivary nuclei, and heterotopic nuclei in the white matter of the cerebellum. Although the hindbrain abnormalities in this case are different from those previously reported, they all have in common an intimate developmental relationship with the same embryological areas. This study suggests that the Coffin-Siris syndrome is a neurocutaneous disorder with hindbrain abnormalities in cerebellum and brain stem.

Full Text Available Foregut in D. hominis (Linnaeus Jr., 1781 as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the foregut. Metamoiphosis begins at the end of the larval period with signs of nuclear degeneration of all the polytenic cells, as well as the increase in number of the imaginal disk ones. The oesophagic portion intussuscepted into the cardia, everts; its cells suffer apoptosis and are replaced by the new cells growing from the imaginal disk. The external layer cells also degenerate and are pinched off into the lumen of the very anterior portion of the midgut. The newly formed oesophagus intussuscepts "de novo" to form the two internal layers of the adult cardia. At the same time the midgut regenerative cells grow anteriorly to form the new external layer of the adult cardia.

2007-11-01

Full Text Available Abstract Background Heterotopic gastric mucosa (HGM is commonly seen in the upper esophagus during endoscopyand is generally considered a benign disease. A hyperplastic polyp and an adenocarcinoma arising in heterotopic gastric mucosa are quite rare occurences. Case presentations We present two cases: The first is a patient who suffered from dysphagia because of a large hyperplastic polyp that arose from HGM; the polyp was excised endoscopically. Secondly, we report a rare case of adenocarcinoma arising in HGM of the cervical esophagus. Conclusion Morphologic changes or malignant transformation can develop in the inlet patch. Therefore, gastroenterologists should be aware of the possibility of HGM just distal to the upper esophageal sphincter.

Computed Tomography in the Diagnosis of Myositis Ossificans – Case Report

International Nuclear Information System (INIS)

Nitek, Żaneta; Czwojdziński, Adam; Wolf-Kuś, Alicja; Walecki, Jerzy

2014-01-01

The term myositis ossificans refers to the formation of ossifications in the muscles, ligaments and fascias, usually as a result of trauma. Fibrodysplasia ossificans progressiva is a rare genetic disease in which heterotopic ossifications appear in early childhood and are accompanied by feet and spine defects. We present a case of a 31-year-old woman with massive heterotopic ossifications who suffered multiple injuries. We would like to emphasize the role of computed tomography in the exact localization of ossifications. Thanks to the volume rendering techniques and 3D image reconstructions, it is possible to precisely determine the position of ossifications in relation to the internal organs and blood vessels, allowing to schedule the surgery to remove the lesions

New approaches in oral rotavirus vaccines.

Science.gov (United States)

Kuate Defo, Zenas; Lee, Byong

2016-05-01

Rotavirus is the leading cause of severe dehydrating diarrhea worldwide, and affects primarily developing nations, in large part because of the inaccessibility of vaccines and high rates of mortality present therein. At present, there exist two oral rotaviral vaccines, Rotarix™ and RotaTeq™. These vaccines are generally effective in their actions: however, associated costs often stymie their effectiveness, and they continue to be associated with a slight risk of intussusception. While different programs are being implemented worldwide to enhance vaccine distribution and monitor vaccine administration for possible intussusception in light of recent WHO recommendation, another major problem persists: that of the reduced efficacy of the existing rotaviral vaccines in developing countries over time. The development of new oral rotavirus vaccine classes - live-attenuated vaccines, virus-like particles, lactic acid bacteria-containing vaccines, combination therapy with immunoglobulins, and biodegradable polymer-encapsulated vaccines - could potentially circumvent these problems.

Accurate and reliable imaging of pelvic floor dynamics is important for tailoring treatment in pelvic floor disorders; however, two imaging modalities are available. Barium proctography (BaP) is widely used, but involves a significant radiation dose. Magnetic resonance (MR) proctography allows visualization of all pelvic midline structures but patients are supine. This project investigates whether there are measurable differences between BaP and MR proctography. Patient preference for the tests was also investigated. Consecutive patients referred for BaP were invited to participate (National Research Ethics Service approved). Participants underwent BaP in Poole and MR proctography in Dorchester. Proctograms were reported by a consultant radiologist with pelvic floor subspecialization. A total of 71 patients were recruited. Both tests were carried out on 42 patients. Complete rectal emptying was observed in 29% (12/42) on BaP and in 2% (1/42) on MR proctography. Anismus was reported in 29% (12/42) on BaP and 43% (18/42) on MR proctography. MR proctography missed 31% (11/35) of rectal intussusception detected on BaP. In 10 of these cases no rectal evacuation was achieved during MR proctography. The measure of agreement between grade of rectal intussusception was fair (κ=0.260) although MR proctography tended to underestimate the grade. Rectoceles were extremely common but clinically relevant differences in size were evident. Patients reported that they found MR proctography less embarrassing but harder to empty their bowel. The results demonstrate that MR proctography under-reports pelvic floor abnormalities especially where there has been poor rectal evacuation. © 2012 The Authors.

Jacob George

2005-01-01

Full Text Available A 13-year-old girl with seizure disorder presented with 90º fixed flexion deformity of right elbow. She had history of encephalitis, 2 years ago, from which she recovered completely except for the deformity of the elbow. Plain X-ray revealed extensive ossification of the brachialis muscle from its origin at the lower anterior aspect of the humerus to its insertion at the coronoid process of the ulna. The alkaline phosphatase value was 500 IU. The middle segment of the ossified mass was surgically excised. The mobility of the elbow was restored and she achieved a range of movement between 45–120º.

Prevention of heterotopic ossification about the hip using perioperative radiotherapy: Results of two randomized trials in 410 patients

1996-01-01

BACKGROUND: In-vivo data (Kantorowitz et al., 1991) indicate the efficacy of pre- and postoperative radiotherapy (RT) in suppressing development of heterotopic ossification (HO) after hip surgery. Since 1987 two prospective randomized trials were initiated at our institution to assess the comparative efficacy of 'high-dose RT' versus 'low-dose RT' (HOP study 1) and 'preoperative RT' versus 'postoperative RT' (HOP study 2). A control arm without radiotherapy (RT) was avoided, as only those patients (pts) were entered, who had a very high risk to develop HO after hip arthroplasty. PATIENTS and METHODS: In HOP study 1 (accrual: June 1987 - June 1992), 249 pts were randomized between the following postoperative RT schedules: 'low-dose RT' with 5 x 2 Gy, 10 Gy total RT dose (N = 129) versus 'high dose RT' with 5 x 3.5 Gy, 17.5 Gy total RT dose (N = 121); RT was applied with daily fractionation starting at postoperative day 1 - 4. In HOP study 2 (accrual : July 1992 - July 1995), 161 pts were randomized between 'preoperative RT' using a single dose of 7 Gy (N = 80 pts) and postoperative RT with 5 x 3.5 Gy (N = 51 pts). In both studies only patients were includes with one or multiple of the following risk factors for HO: ipsi- (55%) or contralateral HO (33%), hypertrophic osteoarthritis (48%), repeated hip surgery, acetabular fracture or severe hip trauma (43%); 62% of all pts had at least two risk factors. The structure of the relevant and possibly confounding patient and disease parameters and risk factors was similar in each of the treatment arms within the two randomized studies. - The assessment of 'treatment failures' was based upon the comparison of the amount of HO seen on the immediately postoperative radiograph as compared to radiographs obtained at least 6 months after surgery (Brooker Score). Any progression of HO by Brooker score was regarded as treatment failure. RESULTS: At last FU, in January 1996 both studies 369 of 410 pts (90%) had received an effective

1985-10-01

In this paper, an account is given of our experience with continent colostomy in man. In five patients, the end-sigmoidostomy was provided with an intussusception valve. Evacuation of the bowel by irrigation through a catheter was laborious and time-consuming and this method was abandoned. In another group of 30 patients, the cecum was isolated from the rest of the colon and its distal end was provided with an intussusception valve. Of the 30 patients, eight were later given continent ileostomies, two were converted to conventional sigmoidostomies, and one patient with fecal incontinence preferred to have intestinal continuity reestablished. Thus, 19 patients still have continent cecostomies and are satisfied with their function. When comparing the function of the continent cecostomy with that of the continent ileostomy, however, it is obvious that the ileostomy function is superior. The experience obtained with this group of patients has resulted in a widening of the indications for constructing a continent ileostomy, including selected patients with various anorectal disorders.

Objective: The aim of this study is to describe the main radiological aspects of postoperative intestinal obstruction in patients submitted to Roux-en-Y gastric bypass by means of the Higa's technique. Materials and methods: A total of 10 patients presenting with postoperative intestinal obstruction following a gastric reduction procedure were evaluated in the period between November 2001 and April 2006, in seven different medical centers. Results: In the ten patients, the obstruction occurred in the small bowel, five of them because of internal hernias, three because of adhesions, one because of an umbilical hernia and one because of intussusception. Four patients presented obstruction early in the postoperative period (by the seventh post-op day), and six, late in the postoperative period (between the third month and the fifth year). Conclusion: All of the cases of intestinal obstruction were found in the small bowel. Internal hernia was the most frequent cause, followed by adhesion. Other causes included umbilical hernia and intussusception. (author)

Rotavirus vaccines

2006-01-01

Full Text Available Rotavirus, the most common cause of severe diarrhea and a leading cause of mortality in children, has been a priority target for vaccine development for the past several years. The first rotavirus vaccine licensed in the United States was withdrawn because of an association of the vaccine with intussusception. However, the need for a vaccine is greatest in the developing world, because the benefits of preventing deaths due to rotavirus disease are substantially greater than the risk of intussusception. Early vaccines were based on animal strains. More recently developed and licenced vaccines are either animal-human reassortants or are based on human strains. In India, two candidate vaccines are in the development process, but have not yet reached efficacy trials. Many challenges regarding vaccine efficacy and safety remain. In addition to completing clinical evaluations of vaccines in development in settings with the highest disease burden and virus diversity, there is also a need to consider alternative vaccine development strategies.

Objective: To observe the short and intermediate-term clinical outcomes of porous coated motion (PCM) cervical prosthesis in the treatment of cervical spondylosis. Methods: The 12 (13 levels) patients who were suffered spondylotic myelopathy with PCM cervical prosthesis were treated. Evaluate the clinical outcome by comparing the JOA scores, the position of prosthesis,rotation of motion, the heterotopic ossification and Odom's scales. Results: After the average 6.5 months(3 ∼ 12 months) follow-up, the JOA scales raised from 8.35 ± 1.10 preoperatively to 15.88 ± 0.73 postoperatively (P 0.05). There was no occurrence of failures of prosthesis such as subsidence, loosening, or excursion. Heterotopic ossification was also absent. Conclusion: The clinical outcomes for cervical disc replacement in the treatment of cervical spondylopathy are satisfied. (authors)

F-18-fluoride PET for early diagnosis and evaluation of therapeutic outcome in patients with heterotopic ossification (HO) after recent paraplegia due to spinal cord injury

International Nuclear Information System (INIS)

Baum, R.P.; Niesen, A.; Schmuecking, M.; Przetak, C.; Ruhwedel, H.; Boehm, H.

2002-01-01

Aim: Heterotopic ossification (HO) is the presence of bone in soft tissue. The acquired form of HO most frequently is seen with either musculoskeletal trauma, spinal cord injury or central nervous system injury. Fever, swelling, erythema, and occasional joint tenderness seen in early HO can be difficult to distinguish from cellulitis, osteomyelitis or thrombophlebitis. As compared to paraplegia alone, combination of HO and paraplegia, especially excessive delay of diagnosis, is associated with a significantly higher incidence for thrombosis, immobilization, decubitus leading to a reduced expectation and quality of life. To evaluate the role of F-18-fluoride PET for the early diagnosis and the evaluation of the therapeutic outcome, 38 patients (56 PET examinations) were analyzed prospectively. Material and Methods: Within 8 weeks after acquired paraplegia, each patient was studied by F-18-fluoride PET in addition to clinical, serologic and conventional radiographic examinations. Whole-body PET studies (ECAT Exact 47, attenuation corrected, iterative reconstruction) were obtained 150 min. after injection of 12 MBq F-18-fluoride/kg body weight. For semi-quantitative analysis, standardized-uptake values (SUV) and the metabolic transverse diameters (MTD) of the lesions were assessed. To prevent post-traumatic neurogenic HO, patients received physiotherapy and NSA (indomethacin 3 x 50 mg per day for 4 months). In addition, external beam radiation therapy (EBRT, 1x7 Gy according to ICRU) was administered, if PET demonstrated HO. Therapeutic outcome was compared with a historical group of patients receiving only physiotherapy. Kaplan-Meier-Method, log-rank-, chi-square- and Wilcoxon-test were used for statistical analyses. Results: In the course of HO, 4/38 patients received EBRT with 1x7 Gy for a second time due to an increasing SUV and/or MTD and rising levels of alkaline phosphatase. Within a follow-up period of at least 30 months, none of the patients showed clinical

T o present the clinical findings of a patient with fibrodysplasia ossificans progressiva (FOP), highlighting peculiarities of dental treatment in patients with this condition. FOP is a rare genetic disease characterized by skeletal malformations and ectopic ossifications in skeletal muscles, tendons, ligaments and aponeurosis. Exacerbation of these ossifications can be caused by dental treatment, resulting in disease progression. A 26-year-old male patient with a diagnosis of FOP was referred to our service for dental treatment. The patient presented decreased mobility in peripheral joints (knees and elbows), postural disability (ankylosis of the vertebral column), lateral deviation and shortness of the hallux, as well as heterotopic ossifications on the hands and back. The implementation of conservative dental procedures, such as oral hygiene instructions and recurrent topical fluoride applications, were performed in addition to endodontic and restorative treatments. Brief dental appointments were conducted without using regional anesthesia or dental dam clamps. The dental chair was positioned at 45° to provide more comfort and to avoid exacerbating the disease. The patient has now completed 6 months of follow-up and is free of heterotopic ossifications resulting from dental treatment. The dental treatment modifications implemented for the present case were sufficient to establish good oral health and to prevent the formation of heterotopic ossifications in the maxillofacial region. FOP is a rare disease dentists must familiarize themselves with to provide adequate, personalized treatment, which minimizes traumas that may exacerbate the disease.

Duplications of the rectum are extremely rare embryologic events, with almost 70 cases reported in the world literature. We report on a 39-year-old female patient with a duplication of the rectum. Physical examination showed a left buttock mass; rectal examination revealed the presence of a painless mass compressing the rectum posterolaterally, confirmed by computerized tomography. The patient was operated on with a abdominal then a sacrococcygeal approach. After a complete excision, the postoperative course was unremarkable. Histology revealed a rectal duplication lined with heterotopic cylindric ciliated epithelium. This case shows that the diagnosis of rectal duplication is difficult and can be confused with other types of anorectal pathology. The presence of heterotopic ciliated epithelium has rarely been described. Complete excision of the duplication should be possible in most cases using a transcoccygeal, transanal, or abdominoperineal approach, depending on anatomic considerations.

Remodeling of the actin cytoskeleton through actin dynamics is involved in a number of biological processes, but its role in human stromal (skeletal) stem cells (hMSCs) differentiation is poorly understood. In the present study, we demonstrated that stabilizing actin filaments by inhibiting gene...... expression of the two main actin depolymerizing factors (ADFs): Cofilin 1 (CFL1) and Destrin (DSTN) in hMSCs, enhanced cell viability and differentiation into osteoblastic cells (OB) in vitro, as well as heterotopic bone formation in vivo. Similarly, treating hMSC with Phalloidin, which is known to stabilize...... polymerized actin filaments, increased hMSCs viability and OB differentiation. Conversely, Cytocholasin D, an inhibitor of actin polymerization, reduced cell viability and inhibited OB differentiation of hMSC. At a molecular level, preventing Cofilin phosphorylation through inhibition of LIM domain kinase 1...
