    Ascariasis is a helminthic infection commonly found in tropical climates. It often propagates in communities of low socioeconomic status secondary to contamination of the soil and water supply with human feces. We present a case report of a 42-year-old Asian-Indian female presenting with a long-standing history of severe recurrent postprandial epigastric pain, requiring multiple hospital admissions. Ultrasound, computed tomography (CT), and nuclear biliary scan were negative. She underwent esophagogastroduodenoscopy that suggested ischemia. Magnetic resonance angiography (MRA) and mesenteric angiography were inconclusive. As conservative treatment had been unsuccessful, a small bowel series was performed. The radiographs demonstrated characteristic findings of Ascaris lumbricoides infestation. Although the prevalence, diagnosis, and subsequent treatment of an acute abdomen secondary to Ascaris lumbricoides infestation is commonly seen in developing countries, clinicians in developed countries may not consider this entity when faced with a patient with similar symptoms. We frequently care for immigrants from developing countries and our own citizens who visit the countries where ascariasis is endemic. Therefore, heightened awareness of Ascaris lumbricoides infection (ALI) presenting as an acute abdomen is necessary. The diagnosis requires an experienced radiologist and knowledge by the clinician of treatment options and of when a surgeon should be involved.

    The popularity in Western countries of dishes based on raw fish has led to an increased incidence of anisakiasis, a human parasitic disease caused by the ingestion of live anisakid larvae. The entire digestive tract may be involved, but the stomach and the small intestine are the most frequently affected sites. We report a case of acute abdomen due to Anisakis simplex infection that caused small bowel obstruction. PMID:15702863

    MDCT has become a fundamental tool for determining the causes of acute abdomen. CT is considered the imaging technique of choice in the diagnostic workup of both localized and diffuse acute abdomen, except in patients in whom acute cholecystitis or acute gynecological disease is suspected and in children, adolescents, and pregnant patients, in whom ultrasonography is the imaging technique of choice. Plain-film X-ray examination has been relegated to the initial management of renal colic, suspected foreign bodies, and intestinal obstruction. One of the drawbacks of MDCT is its use of ionizing radiation, which makes it necessary to filter and direct the examinations as well as to ensure that the most appropriate protocols are used. For this reason, low dose protocols have been developed so that diagnostic studies can be performed with doses of radiation between 2 and 3 mSv; these are normally used in the diagnosis of renal colic and can also be used in selected patients with suspected appendicitis and acute diverticulitis.

    Brucellosis is a zoonotic infection that is transmitted from animals to humans by ingestion of infected food products, direct contact with an infected animal, or aerosol inhalation. The disease is endemic in many countries, including the Mediterranean basin, the Middle East, India, Mexico, Central and South America and, central and southwest Asia. Human brucellosis is a systemic infection with a wide clinical spectrum. Although hepatic involvement is very common during the course of chronic brucellosis, hepatic abscess is a very rare complication of Brucella infection. We present a case of hepatic abscess caused by Brucella, which resembled the clinical presentation of surgical acute abdomen.

    Jejunal pseudo-diverticulosis is a rare acquired herniation of the mucosa and submucosa through weakened areas of the muscularis mucosa of the mesenteric aspect of the bowel. They are asymptomatic in the majority of cases; however, they can present with a wide spectrum of non-specific symptoms such as chronic abdominal discomfort, postprandial flatulence, diarrhoea, malabsorption and steattorhoea. In up to 15% of cases, more serious acute complications may arise such as the development of intestinal obstruction, haemorrhage or as in our case, localized peritonitis secondary to perforation. Perforation carries an overall mortality rate of up to 40% and exploratory laparotomy followed by copious lavage with segmental resection and primary anastomosis remains the mainstay of managing such sequalae of jejunal pseudo-diverticulosis. Our case report highlights the importance of maintaining a high clinical suspicion of a perforated jejunal diverticulum in an elderly patient presenting with an acute abdomen. PMID:27765806

    The authors share their experience in treating children aged 1 day to 14 years with acute processes in the abdomen induced by various tumors. During 10 years 51 patients have been observed. "Acute abdomen" was induced by tumors and cysts of ovaries (16 patients), lymphangiomas, cysts and tumors of the mesentery, greater and lesser omentum, retroperitoneal cavity (14 patients), intestinal tumors (7), small pelvis tumors (6), tumors of kidneys (4), liver (3), cyst of the pancreatic gland (1). The clinical picture of the disease, possible timely diagnosing and tactics are presented. All the patients were operated urgently. After operation 44 patients recovered and were discharged from the hospital, 7 patients died.

    Postpartum Ovarian Vein Thrombosis (POVT) is a rare, but serious condition that causes slow quadrant pain in the postpartum period. POVT must be considered in the differential diagnosis of postpartum acute abdomen. We hereby report a case on a 36-year-old Italian woman who developed an acute abdomen a week after spontaneous vaginal delivery. She had persistent fever and constipation. Diagnosis of POVT was made with an abdominal Computed Tomography (CT) and treatment with heparin and broad-spectrum antibiotics were started. After 72 hours, the patient was switched from low molecular weight heparin to oral anticoagulant treatment. After 5 months a complete recanalization was demonstrated by abdomen CT and the treatment was stopped 6 months after diagnosis. POVT is a diagnosis of exclusion in the puerperium. This case illustrated that POVT may also occur in low risk patient. PMID:27042537

    Acute abdominal pain in childhood is a frequent reason for a medical consultation. The main diseases that lead to the clinical situation of acute abdomen show a significant age dependency. It is reasonable to group such ailments into three age categories: (1) the neonatal and infant period, (2) toddlerhood to kindergarten and (3) school age children. The task of the pediatric radiological examination is the differential diagnostic correlation of symptoms to the respective diseases. In children ultrasound is the appropriate method of choice.

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

    Abdominal involvement in brucellosis is seen in the acute, subacute and chronic disease. It is not typical, however, that acute abdomen is the presenting feature of brucellosis. In this paper, two cases of serologically diagnosed brucellosis are reported, both presenting initially with acute abdomen and fever. In brucella-endemic regions of the world, brucellosis has to be considered in the differential diagnosis of acute abdomen and fever. With definitive diagnosis, unnecessary laparotomy can be avoided.

    Background Gardner's syndrome can occasionally be complicated with intra-abdominal desmoid tumor. These tumors usually remain asymptomatic but can exhibit symptoms due to intestinal, vascular and ureteral compression and obstruction. Case presentation A rare case of a 41-year-old male patient with Gardner's syndrome complicated with intra-abdominal desmoid tumor, which first presented as acute abdomen, is presented. Conclusion Extra-abdominal manifestations of Gardner's syndrome along with a palpable abdominal mass would raise suspicion for the presence of a desmoid tumor in the majority of cases. In life-threatening cases, surgical treatment should be considered as a palliative approach, though the extent of excision remains debatable PMID:16569244

    Torsion of the greater omentum is a rare cause of acute abdomen. Based on etiopathogenesis, it can be classified as primary or secondary. However, regardless of the cause, segmentary or diffuse omental necrosis will follow. Preoperative diagnosis is not easy, though abdominal ultrasound and computed tomography (CT) scans may show peculiar features suggestive of omental torsion. Laparoscopic resection of the affected omentum is the treatment of choice. Presently reported was a case of primary omental torsion, in addition to a comprehensive literature review. PMID:27598614

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

    Antecedentes: la enteritis eosinofílica es un padecimiento raro y los casos de abdomen agudo que origina suponen un mínimo porcentaje. Su etiología aún no está aclarada pero se asocia con enfermedades del colágeno, intolerancias alimentarias e infestaciones por parásitos, como anisakis, descubierto en una de las histologías de nuestros casos. Casos clínicos: de 1997 a 2011 se diagnosticaron seis casos de abdomen agudo; en tres de ellos la enteritis eosinofílica causó necrosis irreversible de un segmento intestinal y hubo que practicar una resección intestinal segmentaria. En dos de ellos había un segmento intestinal con aspecto inflamatorio, que fue el único hallazgo causante del cuadro agudo y en los que sólo se practicó biopsia y otro caso donde fue un hallazgo sin relación con el proceso agudo. Conclusiones: la enteritis eosinofílica puede ocasionar cuadros de abdomen agudo que requieren intervención quirúrgica urgente. El aspecto intraoperatorio es el de un segmento con aspecto inflamatorio que puede llegar a ser macroscópicamente irreversible y donde sólo la resección parcial es el tratamiento correcto, que puede hacerse por vía laparoscópica.

    Acute abdomen is a rare entity in the pregnant patient, with an incidence of one in 500-635 patients. Its appearance requires a quick response and an early diagnosis to treat the underlying disease and prevent maternal and fetal morbidity. Imaging tests are essential, due to clinical and laboratory masking in this subgroup. Appendicitis and complicated biliary pathology are the most frequent causes of non-obstetric acute abdomen in the pregnant patient. The decision to operate, the timing, and the surgical approach are essential for a correct management of this pathology.

    It is well known that half of the cases admitted to hospital emergency services complain of abdominal pain and that nearly half of these cases are diagnosed with nonspecific abdominal pain. The population of patients with celiac sprue is rarely encountered at the emergency room. Although acute abdominal pain is rarely seen in adult celiac sprue, it should be added to the differential diagnosis. It should also be remembered that acute abdominal pain in these patients could be originating from perforation, intussusceptions and/or intestinal lymphoma. Herein we report a case of adult celiac sprue where successful surgical exploration was carried out because of entero-enteral intussusception. PMID:17602358

    We present a retrospective study based on 50 diabetic patients with acute abdominal diseases. Usually, clinical features were not typical, without defining signs of acute abdomen, despite frequent severe anatomo-pathological forms (6 of 12 acute appendicitis were gangrenous, with generalised or localised peritonitis; 15 of 22 acute colecystitis were gangrenous). In diabetic patients, with metabolic disorders and cetoacidosis, positive diagnosis and the decision of laparotomy are difficult problems, often delated, with a negative influence on the evolutions and prognosis of these patients.

    We present the case of a 58-year old male patient admitted in the surgery section of the University Emergency Hospital of Bucharest and diagnosed with acute abdomen. The minimal clinical-paraclinical investigation (i.e., thorax-pulmonary Xray, biological probes) raises questions as to the differentiated diagnosis and other associated diseases, also suggesting the existence of voluminous diaphragmatic hernia. The CT thorax-abdomen examination confirms the diaphragmatic hernia suspicion, with intra-thorax ascent of the colon up to the anterior C4 level, but does not explain the abdominal suffering; thus we suspected a biliary ileus or acute appendicitis. Medial laparotomy was imperative. Intrasurgically peritonitis was noticed located by gangrenous acute apendicitis, perforated, with coprolite, for which apendictomy and lavage-drainage pf the peritoneal cavity was performed. Post-surgical status: favourable to recovery.

    Undescended testicle is the most common congenital anomaly among males. Testicular tumor develops in 3–5% of the boys with a complaint of undescended testicle. The clinical presentation of malignant intra-abdominal testicular tumors ranges from asymptomatic cases to acute abdomen. In this study, we present a child with testicular tumor rupture which is observed very rarely. A 16-year-old boy presented 24 hours after the sudden onset of right lower quadrant pain, nausea, vomiting and fever. On physical examination, extensive tenderness in the abdomen and abdominal guarding were found. The right testicle was not palpable. The serum white blood cell count was elevated. Ultrasonography and abdominal computerized tomography scan demonstrated a perforated, hyperdense mass with free fluid in the abdomen. The preoperative alpha fetoprotein level was found to be increased. We performed surgery with laparoscopy and a perforated right intraabdominal testicle was found in the right iliac fossa. The mass was excised. Histopathological examination revealed a yolk sac tumor. Ruptured nonpalpable testicular tumors are very rare. To our knowledge, this is the first adolescent case reported so far. Testicular tumor rupture should be considered in patients with nonpalpable testicle and acute abdomen. Laparoscopy may be performed in differential diagnosis and treatment of these patients. PMID:27738401

    Hepatic adenomas are uncommon benign tumours of the liver which may eventually present with acute onset following rupture of the lesion and haemorrhage. We present here a unique case of strangulated adenoma of the liver presenting as acute abdomen. A 27-year-old woman taking oral contraceptives, presented to the emergency department with abdominal pain, palpable abdominal mass, fever, and neutrophilia. An abdominal ultrasound showed a 3-cm hepatic nodule and an 11-cm mesogastric mass. Computed tomography of the abdomen revealed a 2.3-cm liver adenoma and a 13-cm pedunculated mass of the liver showing no contrast enhancement suggestive of pedicle torsion with ischemia of the mass. The patient underwent an emergent open resection of the strangulated liver mass, she recovered without complications, and was discharged home after three days. Final pathology confirmed an hepatocellular adenoma with areas of necrosis and hemorrhage. The clinical significance of the disease is discussed.

    Among 328 patients with dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS), 14 (4 men and 10 women, median age 44 years) had acute abdomen. DHF/DSS was initially suspected in only 2 of these 14 patients. Presumptive diagnoses of acute cholecystitis (6 acalculus and 4 calculus cholecystitis) were made in 10 patients, non-specific peritonitis in three patients, and acute appendicitis in one patients. Cholecystectomy, percutaneous transhepatic gallbladder drainage, and appendectomy were performed in three patients. Transfused blood in the three patients who underwent invasive procedures and the 11 patients who received supportive treatment included packed red blood cells (24 versus 0 units; P = 0.048), fresh frozen plasma (84 versus 0 units; P = 0.048), and platelets (192 versus 180 units; P = 0.003). Patients who underwent invasive procedures also had prolonged time in the hospital (median = 11 versus 7 days; P = 0.015). To avoid unnecessary invasive procedure-related morbidity and mortality, this report underscores the importance of a careful differential diagnosis in patients with acute abdomen in a dengue-endemic setting.

  15. The role of gasless laparoscopy in differential diagnosis of acute abdomen

    Background: The diagnosis of acute abdomen in the emergency setting, still remains a challenging problem. In these cases timely diagnosis and management is of great importance, while the anesthetic risk is high. The combination of the risk of an open laparotomy and the relative high likelihood of negative findings when performed, creates the need for a better approach. The alternative actually exists since 1911 when Eruheim made the first gasless laparoscopy. The aim of this study is to put back into the spotlight, gasless laparoscopy in the differential diagnosis of acute abdomen and to underline the advantages of this simple, cheap and very useful technique, especially in patients that require prompt diagnosis and have relative or absolute contraindications to general anesthesia or pneumoperitoneum. Methods: This study included 49 patients that were managed with gasless laparoscopy for the diagnosis of acute abdomen, from 2011 to 2013. Two techniques were used: the mechanical lift of the anterior abdominal wall and the LapVision device. Results: From the 49 patients included in the study, 41 were diagnosed with gasless laparoscopy while in eight the results were uncertain or there wasn’t any pathology involved. With both techniques used, sample of the intraperitoneal fluid or biopsy could be obtained. Conclusion: The gasless technique for laparoscopy is an extremely useful mean of diagnosis in emergency conditions, or for patients with contraindications to undergo laparoscopy by pneumoperitoneum. Requiring only local or regional anesthesia, this technique could easily find application in diagnosis and treatment, while avoiding unnecessary laparotomies. Hippokratia 2015, 19 (1): 69-72.

    Adrenal gland pseudocysts are not common conditions, and most of them are nonfunctional and asymptomatic. However, large pseudocysts may causes abdominal discomfort and have compressive effects on adjacent organs. They may rupture spontaneously or after trauma, and lead to retroperitoneal hemorrhage and surgical emergency. Herein, we report a case of 21-year-old female who presented with acute abdomen and hemorrhagic shock due to spontaneous rupture of adrenal pseudocyst. She was treated successfully by open surgery, removal of adrenal pseudocyst and unilateral adrenalectomy.

    The susceptibility of the undescended testis to malignant transformation is well documented. The most common location of the undescended testis is within the inguinal canal, with only a minority located within the abdominal cavity. When a testicular mass develops, the risk of torsion increases. We describe a large intra-abdominal testicular seminoma that had undergone torsion, rupture and haemorrhage, presenting as an acute abdomen. A 30 year old man presented to the emergency department with right iliac fossa pain. Computed tomography in the emergency department showed haemoperitoneum and a torted large left testicular mass, likely malignant. The patient underwent laparotomy and excision of the mass. Histologic examination revealed a grossly enlarged seminomatous testis which had torted and ruptured. While pre-operative imaging diagnosis of an intra-abdominal testicular seminoma has been published, reports are few. To the best of the author's knowledge pre-operative imaging diagnosis of a malignant testicular mass with torsion and intra-abdominal haemorrhage presenting as an acute abdomen has not been described before.

    2013-01-01

    Acute abdominal pain is a common complaint in pediatric emergency departments. A complete evaluation is the key factor approaching the disease and should include the patient’s age, any trauma history, the onset and chronicity of the pain, the related symptoms and a detailed physical examination. The aim of this review article is to provide some information for physicians in pediatric emergency departments, with the age factors and several causes of non-traumatic acute abdominal pain. The leading causes of acute abdominal pain are divided into four age groups: infants younger than 2 years old, children 2 to 5, children 5 to 12, and children older than 12 years old. We review the information about acute appendicitis, intussusception, Henoch-Schönlein purpura, infection, Meckel’s diverticulum and mesenteric adenitis. In conclusion, the etiologies of acute abdomen in children admitted to the emergency department vary depending on age. A complete history and detailed physical examination, as well as abdominal imaging examinations, could provide useful information for physicians in the emergency department to narrow the differential diagnosis of abdominal emergencies and give a timely treatment.

    Patient: Female, 43 Final Diagnosis: Myeloid sarcoma appendicitis Symptoms: Abdominal pain • chills • fever Medication: — Clinical Procedure: Laparoscopic appendectomy, bone marrow biopsy Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: The gastrointestinal tract is a rare site for extramedullary involvement in acute promyelocytic leukemia (APL). Case Report: A 43-year-old female with no past medical history presented complaining of mild abdominal pain, fever, and chills for the past day. On examination, she was tachycardic and febrile, with mild tenderness of her right lower quadrant and without signs of peritoneal irritation. Laboratory examination revealed pancytopenia and DIC, with a fibrinogen level of 290 mg/dL. CT of the abdomen showed a thickened and hyperemic appendix without perforation or abscess, compatible with acute appendicitis. The patient was given IV broad-spectrum antibiotics and was transfused with packed red blood cells and platelets. She underwent uncomplicated laparoscopic appendectomy and bone marrow biopsy, which revealed neo-plastic cells of 90% of the total bone marrow cellularity. Flow cytometry indicated presence of 92.4% of immature myeloid cells with t (15: 17) and q (22: 12) mutations, and FISH analysis for PML-RARA demonstrated a long-form fusion transcript, positive for APL. Appendix pathology described leukemic infiltration with co-expression of myeloperoxidase and CD68, consistent with myeloid sarcoma of the appendix. The patient completed a course of daunorubicin, cytarabine, and all trans-retinoic acid. Repeat bone marrow biopsy demonstrated complete remission. She will follow up with her primary care physician and hematologist/oncologist. Conclusions: Myeloid sarcoma of the appendix in the setting of APL is very rare and it might play a role in the development of acute appendicitis. Urgent management, including bone marrow biopsy for definitive diagnosis and urgent surgical intervention

    Introduction Hemangioma is the most common benign tumor of the liver. Most cases are asymptomatic and do not require treatment. A hemangioma can rarely be pedunculated; as a result, it may undergo torsion and infarction, which can make it symptomatic. Case Presentation We report the case of a 45-year-old woman with acute abdominal pain due to torsion of a giant pedunculated hepatic hemangioma around its vascular stalk. Conclusions Pedunculated hemangioma of the liver is an uncommon benign tumor, a rare differential diagnosis for a mass located in the upper abdomen. All incidentally detected pedunculated hemangiomas must be surgically managed, as these have a tendency to become torsioned, and there is also a risk of malignancy or rupture.

    Digestive disorders caused by sudden changes in diet or inappropriate diet are among the most common disorders of the digestive system. Cecal or intestinal tympany, one consequence of inappropriate diet, is characterized by the accumulation of gases, marked distension of the cecum and colon and the induction of inflammatory processes. To know the effects of intestinal tympany on the enteric plexuses, we developed a method of experimental tympanic colic (TC) in the Chinchilla lanigera. This species was used in view of its susceptibility to TC. TC was induced with a diet rich in alfalfa associated with grain overload for two weeks. Physical and clinical examination including the von Frey test confirmed the diagnosis. The chinchillas with acute abdomen were treated with 1% ketoprofen and resumption of a balanced diet. Necropsy and histopathological analysis showed tympany-induced alterations mainly in the cecum and colon. After treatment, the control conditions were restored. The TC protocol is proposed as an experimental approach designed to aid the study of the effects of acute intestinal inflammation and obstruction caused by an inappropriate diet. PMID:25324875

    Lymphangioma is a rare, benign lesion derived from a malformation of the lymphatic system, which is more frequently found in the head, neck, and axilla. However, it may be present anywhere in the body, and the diagnosis involves adults as children with some distinct clinical features among them. In pediatric patients, abdominal cystic lymphangioma occurs mostly in the mesentery presenting abdominal pain, intestinal obstruction, or, more rarely, hemorrhage. The authors report the case of a child with a short-course history of fever, abdominal pain, and constipation. The physical examination disclosed the presence of an abdominal mass and signs of peritoneal irritation. Imaging was consistent with a cystic lesion compressing the sigmoid colon and laterally displacing the remaining loops. Exploratory laparotomy was undertaken, and a sigmoidectomy, followed by Hartman’s colostomy, was performed. Histological examination revealed the nature of the lesion as a cystic lymphangioma. The authors highlight the clinical features of this entity and call attention to this disease in the differential diagnosis of acute abdomen or abdominal pain, mainly in pediatric patients.

  3. Abscess of urachal remnants presenting with acute abdomen: a case series

    PubMed Central

    2012-01-01

    Introduction Urachal diseases are rare and may develop from a congenital anomaly in which a persistent or partial reopening of the fetal communication between the bladder and the umbilicus persists. The most frequently reported urachal anomalies in adults are infected urachal cyst and urachal carcinoma. The diagnosis of this entity is not always easy because of the rarity of these diseases and the atypical symptoms at presentation. Imaging techniques, such as ultrasonography and computed tomography have a significant role in recognizing the presence of urachus-derived lesions. Cases presentations Case presentation 1: A 25-year-old Arab-Berber man presented with a 10-day history of progressive lower abdominal pain accompanied by fever, vomiting, and low urinary tract symptoms to our emergency department. Laboratory data revealed leucocytosis. The diagnosis of an acute peritonitis was made initially. Abdominal ultrasonography revealed a hypoechoic tract from the umbilicus to the abdominal wall, and the diagnosis was rectified (infected urachal remnants). The patient was initially treated with intravenous antibiotics in combination with a percutaneous drainage. Afterwards an extraperitoneal excision of the urachal remnant including a cuff of bladder was performed. The histological analysis did not reveal a tumor of the urachal remnant. Follow-up examinations a few months later showed no abnormality. Case presentation 2: A 35-year-old Arab-Berber man, without prior medical history with one week of abdominal pain, nausea and vomiting, associated with fever but without lower urinary tract symptoms visited our emergency department. Laboratory data revealed leucocytosis. Abdominal ultrasonography was not conclusive. Computed tomography of the abdomen was the key to the investigation and the diagnosis of an abscess of urachal remnants was made. The patient underwent the same choice of medical-surgical treatment as previously described for case one, with a good follow

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

    2016-09-01

    Traditionally, the surgical approach to managing abdominal injuries was to assess the extent of trauma, repair any damage and close the abdomen in one definitive procedure rather than leave the abdomen open. With advances in medicine, damage control surgery using temporary abdominal closure methods is being used to manage the open abdomen (OA) when closure is not possible. Although OA management is often observed in traumatic injuries, the extension of damage control surgery concepts, in conjunction with OA, for the management of the septic patient requires that the general surgeon who is faced with these challenges has a comprehensive knowledge of this complex subject. The purpose of this article is to provide guidance to the acute care and general surgeon on the use of OA negative pressure therapy (OA-NPT; ABTHERA™ Open Abdomen Negative Pressure Therapy System, KCI, an ACELITY Company, San Antonio, TX) for OA management. A literature review of published evidence, clinical recommendations on managing the OA and a case study demonstrating OA management using OA-NPT have been included. PMID:27547961

    In the last years, operative laparoscopy became a standard approach in gynaecology and general surgery. Even in pregnancy its use is becoming more widely accepted. In fact, it offers advantages similar to those in no pregnant women, associated with good maternal and fetal outcomes. Around 0.2% of pregnant women require abdominal surgery. The most common indications of laparoscopy in pregnancy are cholelithiasis complications, appendicitis, persistent ovarian cyst and adnexal torsion. Authors describe a very rare case of acute abdomen due to isolated Fallopian tube torsion in a 24th weeks pregnant woman, managed by laparoscopic salpingectomy. PMID:25405198

    Autosomal dominant polycystic kidney disease is an important cause of end stage renal failure. Rarely, these patients may present with hemorrhagic shock caused by rupture of the renal cyst. The aim of this study was to report a rare case of a patient who arrived at the emergency department with autosomal dominant polycystic kidney disease presenting with acute abdominal pain and hemorrhagic shock. A 58-year-old male with chronic renal failure was admitted to the emergency department with acute abdominal pain and hemorrhagic shock. The patient was admitted to the Department of Surgery with diagnosis of acute abdomen and perirenal hematoma. Although the patient was on conservative treatment, his symptoms did not improve and the patient was operated emergently. During exploration, there was bleeding from the right polycystic kidney, which was 30×20 cm in dimension. The patient underwent nephrectomy and drainage of the hematoma, and was discharged on the fifth postoperative day without any problems. Bleeding due to rupture of a cyst in autosomal dominant polycystic kidney disease occurs rarely but it may be life threatening. Although conservative methods are often preferable in treatment, surgery can be life saving for patients in whom the clinical situation does not improve.

    Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis.

    Patients with ureteropelvic junction (UPJ) obstruction can present with flank pain or hematuria. We present 20-year-old male presenting with acute pain in lumbar and right fossa with tenderness and guarding, this case was clinically mimicking general surgical emergency. On computed tomography with urography and angiography, there was 15 cm × 11 cm × 10 cm size non-enhancing hyperdense lesion (average Hounsfield units - +64) in right renal pelvis suggestive of hematoma. Patient's diethylenetriaminepentaacetic acid diuretic renography was suggestive of right kidney glomerular function rate of 48.4 ml/min with the relative function of 43%, Peak to half peak was not achieved. The patient was managed by retrograde ureteropyelography and double J stenting. After 1 month, clot size decreased to 4 cm × 3 cm × 2 cm. The patient had undergone open reduction Anderson hynes dismembered pyeloplasty with the removal of pelvis clot after 6 weeks. We report the first case of UPJ obstruction presenting as an acute abdomen and spontaneous hematuria with large pelvis clot without rupture of the renal pelvis. PMID:27141202

    Retroperitoneal haemorrhage (or retroperitoneal haematoma) refers to an accumulation of blood found in the retroperitoneal space. It is a rare clinical entity with variable aetiology including anticoagulation, ruptured aortic aneurysm, acute pancreatitis, malignancy, and bleeding from renal aneurysm. Diagnosis of retroperitoneal bleed is sometimes missed or delayed as presentation is often nonspecific. Multislice CT and arteriography are important for diagnosis. There is no consensus about the best management plan for patients with retroperitoneal haematoma. Stable patients can be managed with fluid resuscitation, correction of coagulopathy if any, and blood transfusion. Endovascular options involving selective intra-arterial embolisation or stent-grafts are clearly getting more and more popularity. Open repair is usually reserved for cases when there is failure of conservative or endovascular measures to control the bleeding or expertise is unavailable and in cases where the patient is unstable. Mortality of patients with retroperitoneal haematoma remains high if appropriate and timely measures are not taken. Haemorrhage from a benign renal tumour is a rarer entity which is described in this case report which emphasizes that physicians should have a wide index of suspicion when dealing with patients presenting with significant groin, flank, abdominal, or back pain, or haemodynamic instability of unclear cause. Our patient presented with features of acute abdomen and, being pregnant, was thought of having a ruptured ectopic pregnancy. PMID:27429809

    2016-01-01

    Background Acute febrile abdomen represents a diagnostic challenge in patients with autosomal dominant polycystic kidney disease (ADPKD). Although criteria have been proposed for cyst infection (CyI) and hemorrhage (CyH), there is a lack of comparative assessments. Furthermore, distinguishing cystic from non-cystic complications remains problematic. Design ADPKD patients presenting with abdominal pain and/or fever between 01/2005 and 06/2015 were retrospectively identified in a systematic computerized billing database. CyH was defined as spontaneous intracystic density above 50 Hounsfield units on computed tomography (CT). CyI was definite if confirmed by cyst puncture, and probable if 4 criteria were met: 3-day fever, loin/liver tenderness, C-reactive protein (CRP) plasma levels >50mg/L and no CT evidence for CyH. Other episodes were grouped as inflammation of unknown origin (IUO). Results Among a cohort of 173 ADPKD patients, 101 presented with 205 episodes of abdominal pain (n = 172) and/or fever (n = 33). 20 patients experienced 30 CyH, whereas 16 presented 23 episodes of definite (n = 11) or probable (n = 12) CyI. 35 IUO were observed in 31 patients. Clinically, fever was observed in 7% vs. 100% vs. 66% of CyH, CyI and IUO, respectively. Biologically, CRP cut-off at 70 mg/dl showed 92% sensitivity and 81% specificity in CyI diagnosis. Urine or blood cultures remained sterile in >90% of CyH, but were contributive in 53.4% of CyI and IUO, with a 74.2% prevalence for E. coli. Radiologically, ultrasounds, CT and magnetic resonance diagnosed CyI in 2.6%, 20% and 16.7% of cases, respectively. 18F-FDG positron-emission tomography (PET)/CT was done within a median period of 7 days post antibiotics, and significantly changed patient management in 71.4%. Conclusions This retrospective single-center series underscores the usefulness of clinical–fever–and biological–CRP–parameters, but emphasizes the limitations of bacteriological and radiological investigations

She had a history of left lower limb deep vein thrombosis and pulmonary embolism and was taking warfarin potassium. Acute gastroenteritis was suspected and an antibiotic was administered, but symptoms progressed. Abdominal ultrasonography showed occlusion of the left hepatic vein and the middle hepatic vein and her D-dimer level was high. Accordingly, Budd-Chiari syndrome was diagnosed and high-dose intravenous infusion of heparin was initiated. Her abdominal symptoms improved and the levels of inflammatory parameters and D-dimer decreased rapidly. It is known that antiphospholipid syndrome can be complicated by Budd-Chiari syndrome that usually occurs as subacute or chronic onset, but acute onset is rare. It is difficult to diagnose acute Budd-Chiari syndrome complicating antiphospholipid syndrome and this complication generally has a poor outcome.

    2016-01-01

    Background. Inflammatory Fibroid Polyp (IFP) of the colon is an exceedingly rare condition. Since 1952 till now only 32 cases have been reported worldwide of which only 5 were giant (>4 cm) polyps mostly found in the caecum (15 cases) with only 3 in the descending colon. Case Presentation. A 36-year-old female with no previous illness presented to the emergency unit with an acute onset pain over the right hypochondrium for 3 days associated with intermittent fever and anorexia. As she had evidence of localized peritonitis she underwent a diagnostic laparoscopy and subsequently an exploratory laparotomy. A mass measuring 8 × 7 × 5 cm arising from the hepatic flexure of colon was noted. Right hemicolectomy with ileotransverse anastomosis was performed. The mass was subsequently reported to be IFP. Conclusion. IFP is a very rare condition with clinical presentation depending upon its size and location. Definitive diagnosis is possible with histopathological examination of tissue aided by immunohistochemical studies. Surgical resection has been the most common method of treatment especially for large and giant colonic IFPs owing to challenges in terms of diagnosis and technical difficulties associated with endoscopic methods.

    Abdominal complaints are common in the HIV-infected patient, and the signs and symptoms of disease may be masked by concurrent illness and a weak immune response, making accurate diagnosis difficult. Patients with acquired immunodeficiency syndrome (AIDS) are susceptible to diseases common to the general population; however, their generalized state of immunodeficiency places them at increased risk for many unusual disorders, predominately infectious and neoplastic. Radiologic evaluation, in particular, computed tomography (CT) with its ability to image the entire abdomen and pelvis, plays a crucial role in the prompt and accurate diagnosis and treatment of these patients.

    Introduction. We report the management of a septic Open Abdomen (OA) patient by the help of negative pressure therapy (NPT) and abdominal reapproximation anchor (ABRA) system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S) with confounding factor of mild acute pancreatitis (AP). Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR). There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU) with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF) to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient. PMID:27006853

    Introduction. We report the management of a septic Open Abdomen (OA) patient by the help of negative pressure therapy (NPT) and abdominal reapproximation anchor (ABRA) system in pregnant woman with spontaneous jejunal perforation after emergent cesarean section (C/S) with confounding factor of mild acute pancreatitis (AP). Presentation of Case. A 29-year-old and 34-week pregnant woman with AP underwent C/S. She was arrested after anesthesia induction and responded to cardiopulmonary resuscitation (CPR). There were only ash-colored serosanguinous fluid within abdomen during C/S. After C/S, she was transferred to intensive care unit (ICU) with vasopressor support. On postoperative 1st day, she underwent reoperation due to fecal fluid coming near the drainage. Leakage point could not be identified exactly and operation had to be deliberately abbreviated due to hemodynamic instability. NPT was applied. Two days later source control was provided by conversion of enteroatmospheric fistula (EAF) to jejunostomy. ABRA was added and OA was closed. No hernia developed at 10-month follow-up period. Conclusion. NPT application in septic OA patient may gain time to patient until adequate source control could be achieved. Using ABRA in conjunction with NPT increases the fascial closure rate in infected OA patient. PMID:27006853

    Acute cholangitis secondary to ascariasis is rare and occurs mainly in areas of high endemicity. The clinical presentation is non-specific, sometimes complicated by liver abscess. Abdominal ultrasound plays an important role in diagnosis and therapeutic surveillance. We report the case of a 35-year-old Malagasy woman with an acute cholangitis secondary to ascariasis and complicated by liver abscesses and its course to full recovery under medical treatment.

    Streptococcus pyogenes (group A streptococcus) is an aerobic gram-positive coccus that causes infections ranging from non-invasive pharyngitis to severely invasive necrotizing fasciitis. Mutations in csrS/csrR and rgg, negative regulator genes of group A streptococcus, are crucial factors in the pathogenesis of streptococcal toxic shock syndrome, which is a severe, invasive infection characterized by sudden onset of shock and multiorgan failure, resulting in a high mortality rate. Here we present a case of group A streptococcal bacteremia in a 28-year-old Japanese woman with no relevant previous medical history. The patient developed progressive abdominal symptoms that may have been due to spontaneous bacterial peritonitis, followed by a state of shock, which did not fulfill the proposed criteria for streptococcal toxic shock. The isolate was found to harbor a mutation in the negative regulator csrS gene, whereas the csrR and rgg genes were intact. It was noteworthy that this strain carrying a csrS mutation had caused group A streptococcal bacteremia characterized by acute abdomen as the presenting symptom in a young individual who had been previously healthy. This case indicates that group A streptococcus with csrS mutations has potential virulence factors that are associated with the onset of group A streptococcal bacteremia that does not meet the diagnostic criteria for streptococcal toxic shock syndrome.

    A 17-year-old girl presented with bilious vomiting and abdominal pain to the surgery department. The history was positive for trichotillomania and trichophagia. A CT scan showed a mass in the stomach, which was highly suspicious for a gastric bezoar. Drooping parts of the bezoar caused a duodenal obstruction with secondary acute pancreatitis. The bezoar was removed via a laparoscopically performed gastrotomy. PMID:27144047

    Rationale: To assess the importance of the new radiographic sign of faecal loading in the cecum for the diagnosis of acute appendicitis, in comparison with other inflammatory diseases, and to verify the maintenance of this radiographic sign after surgical treatment of appendicitis. Methods: 470 consecutive patients admitted to the hospital due to acute abdomen were prospectively studied: Group 1 [n=170] – diagnosed with acute appendicitis, subdivided into: Subgroup 1A – [n=100] – submitted to an abdominal radiographic study before surgical treatment, Subgroup 1B – [n=70] – patients who had plain abdominal X-rays done before the surgical procedure and also the following day; Group 2 [n=100] – right nephrolithiasis; Group 3 [n=100] – right acute inflammatory pelvic disease; Group 4 [n=100] – acute cholecystitis. The patients of Groups 2,3 and 4 were submitted to abdominal radiography during the pain episode. Results: The sign of faecal loading in the cecum, characterized by hypo transparency interspersed with multiple small foci of hyper transparent images, was present in 97 patients of Subgroup 1A, in 68 patients of Subgroup 1B, in 19 patients of Group 2, in 12 patients of Group 3 and in 13 patients of Group 4. During the postoperative period the radiographic sign disappeared in 66 of the 68 cases that had presented with the sign. The sensitivity of the radiographic sign for acute appendicitis was 97.05% and its specificity was 85.33%. The positive predictive value for acute appendicitis was 78.94% and its negative predictive value was 98. 08%. Discussion: The radiographic image of faecal loading in the cecum is associated with acute appendicitis and disappears after appendectomy. This sign is uncommon in other acute inflammatory diseases of the right side of the abdomen. PMID:22574093

    Acute pharyngotonsillitis is one of the most common diseases in children and adolescents. The most frequent etiology is virus, followed by bacteria. The main bacterial agent is beta hemolytic Streptococcus group A. A rare complication of pharyngeal infectious processes is septic thrombophlebitis of the internal jugular vein. The diagnosis is suspected in the presence of an inflammatory unilateral neck swelling. The diagnosis is confirmed by contrast computed tomography. Treatment consists of prolonged administration of antibiotics, being the use of anticoagulants controversial. Early diagnosis and appropriate treatment are essential to prevent persistent vascular occlusion and progression of the thrombus, which can cause pulmonary emboli. In the present study, we present a teenager with thrombophlebitis of the internal jugular vein secondary to acute streptococcal pharyngotonsillitis. Clinical manifestations, diagnostic methods and treatment of this rare vascular complication are described herein.

    Takotsubo syndrome, also known as broken-heart syndrome, stress-induced cardiomyopathy or transient apical ballooning syndrome, is a transient disorder characterized by segmental left ventricular failure in the absence of obstructive coronary artery disease. Most cases of Takotsubo syndrome are caused by acute stress that leads to a sudden, temporary weakening of the cardiac musculature. This stress triggers a rise in circulating catecholamine levels that results in acute ventricular dysfunction. In this report, we describe two cases of Takotsubo syndrome in the early postoperative period after bariatric surgery.

    We present a case of a 50-year-old woman with acute dacryocystitis that was complicated by posterior rupture of the lacrimal sac causing an orbital cellulitis with subsequent visual acuity of no light perception. Upon presentation, she was immediately started on broad-spectrum antibiotics and underwent surgical incision and drainage of the lacrimal sac abscess but never regained vision. There are 4 cases in the literature of permanent severe vision loss from acute dacryocystitis. Prompt diagnosis and close monitoring of acute dacryocystitis are therefore essential to prevent extension into the orbit and possible optic nerve compromise. PMID:27803829

    Trauma to the neck musculature and cervical spine is frequently caused by hyperextension injuries which may result in muscular spasm or rupture. Partial rupture of the sternocleidomastoid muscle with subsequent formation of a fibrotic band is an unusual cause of acute torticollis. The case of a 21-year-old man who developed an acute torticollis and cervical pain after a motor vehicle accident is presented. Computed tomography scan demonstrated 75% rupture of the left sternocleidomastoid muscle with fibrotic band replacing the absent muscle tissue. Neck range of motion was markedly decreased. The patient underwent a trial of muscle relaxants and intensive physical therapy with no significant improvement. Surgical release of the residual fibrotic band was performed, and the left deviation of the neck was reduced from 25 degrees preoperatively to 5 degrees postoperatively. With surgical release and intensive postoperative physical therapy, the patient regained full motion and strength of the cervical spine musculature.

    Disseminated gonococcal infection (DGI) is a rare complication of primary infection with Neisseria gonorrhoeae. Cardiac involvement in this condition is rare, and is usually limited to endocarditis. However, there are a number of older reports suggestive of direct myocardial involvement. We report a case of a 38-year-old male with HIV who presented with chest pain, pharyngitis, tenosynovitis, and purpuric skin lesions. Transthoracic echocardiogram showed acute biventricular dysfunction. Skin biopsy showed diplococci consistent with disseminated gonococcal infection, and treatment with ceftriaxone improved his symptoms and ejection fraction. Though gonococcal infection was never proven with culture or nucleic acid amplification testing, the clinical picture and histologic findings were highly suggestive of DGI. Clinicians should consider disseminated gonococcal infection when a patient presents with acute myocarditis, especially if there are concurrent skin and joint lesions. PMID:26246922

    Several medications or their metabolites have been associated with urolithiasis, although overall they remain an infrequent cause of urolithiasis. Guaifenesin stones were originally reported as complexed with ephedrine, and subsequent reports have demonstrated pure guaifenesin stones, occurring after long term abuse. We report a case of a 23-year-old male who ingested a large, one time dose of guaifenesin, resulting in acute bilateral ureteral obstruction, which, to our knowledge, is the first such reported case in the literature.

    Cutaneous anaplastic large cell lymphoma (ALCL) is an uncommon diagnosis that may either present as a primary cutaneous process or develop secondary to systemic disease. It is imperative to distinguish between these two entities due to differences in treatment recommendations and prognosis. Here, their salient features will be reviewed. It is also important that clinicians recognize atypical clinical morphologies of cutaneous ALCL, including pustular lesions, which may masquerade as infectious or other inflammatory conditions, thereby delaying the onset of treatment. In this report, we present a case of secondary cutaneous ALCL associated with an atypical pustular morphology and an aggressive, fatal course.

    Poor prognosis is strongly associated with Acute Coronary Syndrome (ACS) and, even though a number of treatment strategies are available, the incidence of subsequent serious complications after an acute event is still high. Statins are hypolipidemic factors and recent studies have demonstrated that they have a protective role during the process of atherogenesis and that they reduce mortality caused by cardiovascular diseases. This review tries to reveal the function of the statins as a component of the primary and secondary action of acute coronary syndrome and to describe the lifestyle changes that have the same effect as the use of statins.

    2011-01-01

    Ischemic colitis (IC) secondary to air embolism from decompression sickness or barotrauma during diving is an extremely rare condition. After extensive review of the available literature, we found that there has been only one reported case of IC secondary to air embolism from diving. Although air embolization from diving and the various medical complications that follow have been well documented, the clinical manifestation of IC from an air embolism during diving is very rare and thus far unstudied. Common symptoms of IC include abdominal pain, bloody or non-bloody diarrhea or nausea or vomiting or any combination. Emergency physicians and Critical Care specialists should consider IC as a potential diagnosis for a patient with the above-mentioned symptoms and a history of recent diving. We report a case of IC from air embolism after a routine dive to 75 feet below sea level in a 53-year-old White female who presented to a community Emergency Department complaining of a 2-day history of diffuse abdominal pain and nausea. She was diagnosed by colonoscopy with biopsies and treated conservatively with antibiotics, bowel rest, and a slow advancement in diet.

    Rhabdomyolysis is a serious medical condition in which the skeletal muscle tissue gets damaged and breaks down at rapid rates, potentially leading to death if not managed early on. Rhabdomyolysis in adults has several etiologies such as crush injuries, prolonged immobilization, strenuous exercise, hormonal or metabolic causes, infections, and drug-drug interactions. We present a case report of the interaction of two drugs that are used commonly in the general population. We here discuss a case of a 60-year-old female who presented to the hospital with complaints of generalized weakness, muscle aches, and atypical chest pain for a week after her primary care physician started her on sitagliptin while she was already on atorvastatin. After review of literature, this is the second known case of such an interaction causing acute breakdown of skeletal musculature. PMID:27199569

    The acute renal failure is a grave pathology, of rapid establishment and relatively frequent in the hospital environment. We can describe three etiological groupS, which are responsible for it, amongst which are emphasized the pre-renal reasons. The obstructive pathology, of minor incidence, increases with the age. It is described the case of a 67-yr-old patient who was admitted in the Nephrology Service because of abrupt decline of the renal function. Among the initial symptoms, he presented arterial hypertension (190/90) and preserved diuresis. Blood analysis: urea 199 mg/dl, creatinine 7.7 mg/dl, without proteinuria. Sonography reported a bilateral ureteral hydronephrosis with simple cyst of possible ischemic origin. In view of the absence of previous biochemical data of renal failure, we considered possible reasons which start with an acute pattern. In initial evaluation, pre-renal etiology was not seen (high blood pressure, right cardiac systole function). The absence of prostatic syndrome and sonography discovery did not justify a diagnosis of urinary tract obstruction. Finally, abdominal-pelvic scan showed a periaortic retroperitoneal mass which included both ureters and appeared to trigger the obstruction. Combined efforts were pursued with the Urology Service, which implanted a bilateral "double J" catheter and later operated surgically on the patient, carrying out an alternating ureterolysis of both ureters. The biopsy manifested a retroperitoneal fibrosis, and the renogram showed a residual renal function of 20% in the right kidney and 80% in the left kidney. Due to the failure of the previous measures and as a last therapeutic recourse when one year had passed from the diagnosis, a continuous regimen with tamoxifen (anti-estrogen drug) in dose of 20 mg/dl each 12 hours was started, which began a progressive remission in the size of the observed mass by scan (CT) and magnetic resonance (MR). The treatment was completed during 12 months and in this time

  14. Persistent pseudobulbar affect secondary to acute disseminated encephalomyelitis

    2015-01-01

    Pseudobulbar affect (PBA) is a common complication of central nervous system diseases such as stroke, multiple sclerosis, and other neurological diseases, but it remains under-recognized and under-treated in the clinic. PBA caused by acute disseminated encephalomyelitis (ADEM) has rarely been reported. Here, we report a 30-year-old Chinese woman who has experienced PBA from ADEM for 7 years. The patient's principal manifestations were extreme emotions or tears when she saw, heard, or spoke about sad news or other sad things; the durations of these unmanageable emotions were often less than 30 sec, and they occurred at frequencies that ranged from one to several times a day. Occasionally, she laughed uncontrollably while people were talking despite a lack of funny or sad stimuli in the conversation or the surrounding environment.

    The formation of aortic thrombi is an extremely rare complication of acute pancreatitis. Here we report a case of acute pancreatitis complicated by a paraesophageal pseudocyst, necrotizing mediastinitis, and the formation of multiple thrombi in the ascending aorta. The patient was successfully treated by surgical therapy, which included extensive debridement of the mediastinum and removal of the aortic thrombi under cardiopulmonary bypass. Although esophageal resection was not carried out concomitantly, the lesions were resolved and the patient remained free of complications over 2 years of follow-up care. PMID:27734004

    A 30-year-old HIV-positive man presented with acute hydrocephalus secondary to tuberculous meningitis, for which an external ventricular drain was inserted. He developed marked natriuresis in the postoperative period, which resulted in acute hyponatraemia (131 to 122 mmol/l) and a contraction of his intravascular volume. A diagnosis of cerebral salt wasting syndrome was made, and he responded to sodium and fluid loading. This case highlights the differentiation of cerebral salt wasting syndrome from the more commonly occurring syndrome of inappropriate anti-diuretic hormone secretion as the aetiology of the hyponatraemia.

    Blast cells from five cases of secondary unclassifiable leukemia following therapy for Hodgkin's disease were studied by cytochemical, immunological and cytogenetic analyses. Cytochemical and immunological reactivity were in accordance with poorly differentiated, myeloid blasts. The four cases in which karyotype analysis was performed showed specific chromosomal abnormalities. No evidence of multiple lineage involvement was found. Problems in classifying these cases of secondary ANLL were due to the high grade of undifferentiation of the blast cells. Their low cytochemical reactivity with markers of myeloid differentiation was similar to what may be observed in patients with acute undifferentiated leukemia or with chronic myeloid leukemia in blast crisis.

    Cardiovascular disease is the main health problem in Europe and the rest of the world and is the leading cause of death and health care expenditure. By reducing mortality and ischemic event recurrence, prevention strategies play a fundamental role in patients who have had an acute coronary syndrome. Although these prevention strategies have focused with great success on high-risk individuals, they should also be used in the general population, which is showing an increase in the prevalence of obesity, diabetes mellitus, and other comorbidities that may reverse this trend toward reduced mortality. The present article consists of an up-to-date review of the main cardiovascular prevention measures, particularly the new developments of the last year, as well as the particularities of these measures when they are targeted at patients with a prior acute coronary syndrome.

    BACKGROUND: Acute esophageal variceal bleeding (EVB) is a major cause of morbidity and mortality in patients with liver cirrhosis. Guidelines have been published in 1997; however, variability in the acute management and prevention of EVB rebleeding may occur. METHODS: Gastroenterologists in the provinces of British Columbia, Alberta, Manitoba and Saskatchewan were sent a self-reporting questionnaire. RESULTS: The response rate was 70.4% (86 of 122). Intravenous octreotide was recommended by 93% for EVB patients but the duration was variable. The preferred timing for endoscopy in suspected acute EVB was within 12 h in 75.6% of respondents and within 24 h in 24.6% of respondents. Most (52.3%) gastroenterologists do not routinely use antibiotic prophylaxis in acute EVB patients. The preferred duration of antibiotic therapy was less than three days (35.7%), three to seven days (44.6%), seven to 10 days (10.7%) and throughout hospitalization (8.9%). Methods of secondary prophylaxis included repeat endoscopic therapy (93%) and beta-blocker therapy (84.9%). Most gastroenterologists (80.2%) routinely attempted to titrate beta-blockers to a heart rate of 55 beats/min or a 25% reduction from baseline. The most common form of secondary prophylaxis was a combination of endoscopic and pharmacological therapy (70.9%). CONCLUSIONS: Variability exists in some areas of EVB treatment, especially in areas for which evidence was lacking at the time of the last guideline publication. Gastroenterologists varied in the use of prophylactic antibiotics for acute EVB. More gastroenterologists used combination secondary prophylaxis in the form of band ligation eradication and beta-blocker therapy rather than either treatment alone. Future guidelines may be needed to address these practice differences. PMID:16955150

    Pseudoaneurysm of a cystic artery is a rare entity that commonly occurs secondary to biliary procedures. Most of the cases in literature are consisted of ruptured aneurysms and to our knowledge, except our case, there were only 3 cases with unruptured aneurysms, which incidentally were detected by radiological methods. When cystic artery pseudoaneurysm is present with acute cholecystitis, most of the reports in literature suggested open cholecystectomy with the ligation of the cystic artery as a main treatment option. In this paper we present a case of acute cholecystitis with unruptured cystic artery pseudoaneurysm that incidentally was detected by computed tomography (CT). Cystic artery pseudoaneurysm was handled laparoscopically with simultaneous cholecystectomy. Due to high risk of rupture, surgeons have evaded laparoscopic approach to acute cholecystitis, which accompanied cystic artery pseudoaneurysm. However herein, we proved that laparoscopic management of cystic artery pseudoaneurysm with simultaneous cholecystectomy is feasible and reliable method. PMID:27635274

    Acute gastric dilation is a rare but recognised complication in patients with bulimia and anorexia following binge episodes owing to decreased bowel motility. We present a rare case of acute gastric dilation secondary to bulimia in an otherwise healthy 18-year-old female patient that resulted in compression and complete occlusion of the abdominal aorta, leading to acute mesenteric and bilateral lower limb ischaemia. This resolved immediately following a laparotomy and gastric decompression. Management of these patients is very challenging owing to the lack of a successful precedent. To our knowledge, such a catastrophic complication has only ever been reported once in the literature and the outcome was fatal. Our case is of additional importance as it offers a successful management strategy for these patients.

    2015-01-01

    Many diseases cause substantial changes in the mechanical properties of tissue and this provides motivation for developing methods to non-invasively assess the stiffness of tissue using imaging technology. Magnetic resonance elastography (MRE) has emerged as a versatile MRI-based technique, based on direct visualization of propagating shear waves in the tissues. The most established clinical application of MRE in the abdomen is in chronic liver disease. MRE is currently regarded as the most accurate non-invasive technique for detection and staging of liver fibrosis. Increasing experience and ongoing research is leading to exploration of applications in other abdominal organs. In this review article, the current use of MRE in liver disease and the potential future applications of this technology in other parts of the abdomen are surveyed. PMID:25488346

    Compared to secondary acute myeloid leukemia, secondary acute lymphoblastic leukemia (sALL) is poorly characterized. We utilized data from the Surveillance, Epidemiology, and End Results (SEER) 13 database to further elucidate patient characteristics and prognostic factors in sALL. Cases of adult de novo acute lymphoblastic leukemia (ALL) and sALL in patients with primary breast, rectum, cervix, or ovarian cancers or lymphoma with a latency period of at least 12 months were identified within the SEER 13 database. Survival in sALL and de novo ALL were compared after propensity matching based on age, gender, race, ALL subtype, and year of diagnosis. 4124 cases of de novo ALL and 79 cases of sALL were identified. sALL patients were older at diagnosis (median 62 years vs. 44 years; p<0.01). Overall survival (OS) in sALL was lower than de novo ALL (median 8 months vs. 11 months), 1 year OS: 35% vs. 47% (p=0.05), 2 year OS: 16% vs. 31% (p<0.01), and 5 year OS: 7% vs. 21% (p<0.01). Multivariate analysis revealed sALL as an independent predictor of worsened survival (adjusted HR 1.54; 95% CI 1.16-2.04, p<0.01) after propensity matching.

    Secondary myeloid neoplasia may be a complication of intensive cytostatic therapy. The most common types of secondary neoplasias are acute myeloid leukemia and myelodysplastic syndrome. The development of secondary atypical chronic myeloid leukemia (aCML) is an extremely rare phenomenon. The paper describes transformation of secondary myelodysplastic syndrome to aCML 6 months after its diagnosis. The development of aCML was accompanied by additional chromosomal aberration as monosomy of chromosome 17. No mutations in the JAK2, MPL, and CalR genes were detected. It is concluded that the clinical course of secondary myeloid neoplasias is variable.

    The lymphatic system of the abdomen comprises of the cisterna chyli, its major and minor lymphatic tributaries, and lymph nodes. Disorders of the lymphatic system of the abdomen are rarely encountered and consist of primary and secondary types. Abdominal lymphangiomas constitute the majority and have characteristic imaging features. Complicated lymphangiomas may pose a diagnostic dilemma. Generalised systemic lymphangiomatosis is a rare condition and affects major organs with a poor prognosis. Retroperitoneal lymphangiectasia in the appropriate setting might predict underlying infection, such as filariasis. Other acquired conditions include iatrogenic or treatment-induced chylocoele. Chylous ascites can be secondary to multiple causes and can be confirmed by biochemical testing and lymphangiogram in appropriate settings. PMID:27450410

    We report a case of acute compartment syndrome of the thigh secondary to common femoral vessel injury. The lesion was associated with common femoral artery dissection and common femoral vein rupture. Emergency surgical treatment consisted of resection-anastomosis of the arterial dissection, vein ligature, and fasciotomies. The patient is symptom-free after 15 months of follow-up. Isolated vascular injury is an unusual cause of acute compartment syndrome of the thigh. This case serves to increase awareness that isolated vascular injury, without femoral fracture or multiple injury, can result in thigh compartment syndrome. Early recognition and treatment of vascular involvement contributes to better functional outcome of this rare condition, but treatment modalities remain subject to discussion.

    The current definitive treatment for acute or chronic liver condition, that is, cirrhosis, is liver transplantation from a limited number of donors, which might cause complications after donation. Hence, bone marrow stem cell transplantation has been developed, but the risk of carcinogenesis remains. We have recently developed a protocol for hepatic differentiation of CD117+ stem cells from human exfoliated deciduous teeth (SHED). In the present study, we examine whether SHED hepatically differentiated (hd) in vitro could be used to treat acute liver injury (ALI) and secondary biliary cirrhosis. The CD117+ cell fraction was magnetically separated from SHED and then differentiated into hepatocyte-like cells in vitro. The cells were transplanted into rats with either ALI or induced secondary biliary cirrhosis. Engraftment of human liver cells was determined immunohistochemically and by in situ hybridization. Recovery of liver function was examined by means of histochemical and serological tests. Livers of transplanted animals were strongly positive for human immunohistochemical factors, and in situ hybridization confirmed engraftment of human hepatocytes. The tests for recovery of liver function confirmed the presence of human hepatic markers in the animals' blood serum and lack of fibrosis and functional integration of transplanted human cells into livers. No evidence of malignancy was found. We show that in vitro hdSHED engraft morphologically and functionally into the livers of rats having acute injury or secondary biliary cirrhosis. SHED are readily accessible adult stem cells, capable of proliferating in large numbers before differentiating in vitro. This makes SHED an appropriate and safe stem cell source for regenerative medicine. PMID:25234861

    Clinical practice guidelines can be used to help improve health care quality, but they are often not optimally implemented. Practice enabling and reinforcing techniques, such as clinical reminders and academic detailing are effective methods for translating guidelines into practice. Following a study showing that we could improve adherence to secondary prevention guidelines for acute myocardial infarction (AMI) using computerized alerts and academic detailing, we implemented an automated monitor to accomplish the same goal in a less labor-intensive manner. This paper describes the implementation of this production application. PMID:12463887

We report a 55-year-old Saudi female, known to have atrial fibrillation secondary to mitral stenosis due to rheumatic heart disease. She presented with a two day history of right flank pain that was treated initially as a renal stone. Further investigations confirmed her as a case of renal infarction. Renal infarction is under-diagnosed because the similarity of its presentation to renal stone. Renal infarction should be considered in the differential diagnosis of loin pain, particularly in a patient with atrial fibrillation.

    Hemophagocytic lymphohistiocytosis (HLH) is a rare life-threatening systemic disease, characterized by overwhelming stimulation of the immune system and categorized as primary or secondary types. Occasionally, acute liver failure (ALF) may dominate the clinical presentation. Given the systemic nature of HLH and risk of recurrence, HLH is considered by many a contraindication to liver transplantation (LT). The aim of this study is to review our single-center experience with LT in children with secondary HLH and ALF (HLH-ALF). This is a cross-sectional, retrospective study of children with secondary HLH-ALF that underwent LT in 2005-2014. Of 246 LTs, 9 patients (3 males; median age, 5 years; range, 0.7-15.4 years) underwent LT for secondary HLH-ALF. Disease progression was rapid with median 14 days (range, 6-27 days) between first symptoms and LT. Low fibrinogen/high triglycerides, elevated ferritin, hemophagocytosis on liver biopsy, and soluble interleukin 2 receptor levels were the most commonly fulfilled diagnostic criteria; HLH genetic studies were negative in all patients. Immunosuppressive therapy after LT included corticosteroids adjusted to HLH treatment protocol and tacrolimus. Thymoglobulin (n = 5), etoposide (n = 4), and alemtuzumab (n = 2) were used in cases of recurrence. Five (56%) patients experienced HLH recurrence, 1 requiring repeat LT, and 3 died. Overall graft and patient survival were 60% and 67%, respectively. Six patients are alive and well at a median of 24 months (range, 15-72 months) after transplantation. In conclusion, LT can be beneficial in selected patients with secondary HLH-ALF and can restore good health in an otherwise lethal condition. Liver Transplantation 22 1245-1253 2016 AASLD.

    ABSTRACT OBJECTIVE : To analyze if the demographic and socioeconomic variables, as well as percutaneous coronary intervention are associated with the use of medicines for secondary prevention of acute coronary syndrome. METHODS : In this cohort study, we included 138 patients with acute coronary syndrome, aged 30 years or more and of both sexes. The data were collected at the time of hospital discharge, and after six and twelve months. The outcome of the study was the simultaneous use of medicines recommended for secondary prevention of acute coronary syndrome: platelet antiaggregant, beta-blockers, statins and angiotensin-converting-enzyme inhibitor or angiotensin receptor blocker. The independent variables were: sex, age, education in years of attending, monthly income in tertiles and percutaneous coronary intervention. We described the prevalence of use of each group of medicines with their 95% confidence intervals, as well as the simultaneous use of the four medicines, in all analyzed periods. In the crude analysis, we verified the outcome with the independent variables for each period through the Chi-square test. The adjusted analysis was carried out using Poisson Regression. RESULTS : More than a third of patients (36.2%; 95%CI 28.2;44.3) had the four medicines prescribed at the same time, at the moment of discharge. We did not observe any differences in the prevalence of use in comparison with the two follow-up periods. The most prescribed class of medicines during discharge was platelet antiaggregant (91.3%). In the crude analysis, the demographic and socioeconomic variables were not associated to the outcome in any of the three periods. CONCLUSIONS : The prevalence of simultaneous use of medicines at discharge and in the follow-ups pointed to the under-utilization of this therapy in clinical practice. Intervention strategies are needed to improve the quality of care given to patients that extend beyond the hospital discharge, a critical point of transition

    In a few short years, computed tomography has become an important diagnostic procedure in the examination of the abdomen and pelvis. Its forte lies in its ability to provide cross-sectional views of excellent anatomical detail. Imaging of deep-seated structures such as the pancreas, adrenal glands, and enlarged retroperitoneal lymph nodes is now possible. The ability to distinguish small variations in tissue density enables the radiologist to evaluate the texture of solid structures, and to differentiate them from cysts or abscesses. The addition of contrast enhancement makes it possible to determine the vascularity of a lesson. The major limitation of CT is poorer delineation of structures in thin patients, and in patients in whom voluntary and involuntary motion cannot be interrupted. Computed tomography is compared with other complementary imaging procedures to include sonography, radionuclide imaging, and conventional radiograph procedures. It has replaced invasive diagnostic procedures in many instances. In a given situation, one or more imaging modalities may be appropriate.

    Summary Background Omental cyst and omental torsion both are uncommon but important causes of acute abdomen with a difficult clinical diagnosis due to nonspecific features. Here we report a case of an eight year old child with acute abdominal pain referred for USG and CT scan which revealed two cysts in greater omentum leading to secondary omental torsion. Case Report An eight year old male child presented to casualty with severe pain abdomen since 1 day. There was no history of vomiting or altered bowel habits. The patient was febrile with tachycardia on arrival. On examination rigidity and tenderness all over abdomen were present. Serum amylase was within normal range. USG and CECT abdomen were done subsequently. USG showed two well defined cystic lesions in lower abdomen with presence of some internal echogenic debris and calcified foci in their dependent part. There was also presence of omentum with a whirl of blood vessels seen along anterior abdominal wall leading to these lesions suggesting torsion. On colour Doppler the presence of blood flow within the whirl of vessels was seen. Mild amount of free fluid was also seen in the peritoneal cavity. On CECT abdomen the findings of omental cysts and torsion of greater omentum with free fluid in abdomen were confirmed. The cysts measured 60×55 and 65×55mm on CT. The patient was taken for an emergency laparotomy for indication of acute generalized peritonitis. Two large omental cysts were found in the pelvic cavity along with torsed greater omentum along with 150 ml of hemorrhagic fluid in peritoneal cavity. The cysts and twisted necrotic part of the greater omentum were excised at surgery. No postoperative complications were observed. Histopathologic examination was suggestive of lymphangioma of omentum. Conclusions Lymphangioma of the omentum is an not very uncommon however acute presentation with omental torsion and infarction is an unusual entity. Optimal utilization of preoperative imaging with USG, Doppler

    Acute rhinosinusitis is frequently associated with secondary orbital infection, most commonly subperiosteal abscess. Although orbital subperiosteal abscess is a deadly disease that might lead to blind and cavernous sinus thrombosis, recent review of literature showed that immediate surgical intervention might not always be necessary for subperiosteal abscess. Orbital inflammation secondary to sinusitis is common in children, whereas orbital subperiosteal hematoma secondary to sinusitis is extremely rare, with only 11 reported cases, including one case in children. All the cases were treated with surgical intervention. Here we present a 12-year-old girl with rhinosinusitis and proptosis. Emergent endoscopic sinus surgery with partial removal of the lamina papyracea revealed dark brown fluid in the subperiosteal space. The patient was symptom-free 2 weeks after surgery. The present case was treated exclusively via an endonasal approach, whereas all 11 previous cases of subperiosteal hematoma were treated with external incision. The endonasal approach is favorable, especially for young female patients. Our review of literature shows that sudden onset, afebrile, and few signs of inflammation on blood test in patients with subperiosteal lesion may indicate subperiosteal hematoma. Surgery rather than antibiotic administration should be considered for the treatment of suspected subperiosteal hematoma. Treatment through only the endonasal approach is possible even if the hematoma is located in the roof of the orbit. PMID:24965687

    Although cardiovascular disease mortality rates seem to decline, especially among middle-aged people in developed countries, the prevalence of acute coronary syndrome (ACS) increases, representing the most common cause of morbidity in both developed and developing countries and generating large economic burden. It is estimated that one fifth of the ACS patients die suddenly and half of them belong to a fast growing popula- tion age-group, i.e., those between 70 and .80 years. A substantial number of these deaths has been attributed to various lifestyles, modifiable factors; therefore, it can be prevented. However, factors such as dietary habits and behaviours, physical activity, life stress and smoking habits, although thoroughly discussed, are not well understood and appreciated in the spectrum of secondary ACS prevention. The latter deserves further attention under the prism of socio-economic status that has changed dramatically in the last years in some populations. The aim of this review was to discuss the role of lifestyle factors on secondary ACS prevention under the prism of individual's socio-economic status. Based on the retrieved information it was revealed that there is vast evidence that secondary prevention of cardiovascular events cannot be accomplished simply through medical treatment, but it requires a multifaceted approach incorporating lifestyle modifications, too. Therefore, public health policy endeavours should be directed towards multifocal strategies, i.e., to motivate and support cardiac patients to consistently follow treatment regimens and to establish more effective and efficient community lifestyle interventions.

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

    The deep midpalmar space of the hand communicates with the space of Parona in the forearm. Infection of these deep spaces can be difficult to diagnose. This article presents the first reported case of acute compartment syndrome of the forearm secondary to infection within the space of Parona. This article discusses the anatomy of the space of Parona, highlighting its communicating spaces and the importance of recognizing a deep-space infection of the hand as a possible cause of compartment syndrome of the forearm. This article also suggests a method of clinical examination to aid in the diagnosis of infection within the space of Parona to allow more specific planning of surgical intervention through early decompressive surgery, with surgical exploration to exclude and drain infection when no other clear cause for the rise in pressure within the osteofascial compartment is apparent.

    Secondary leptomeningeal dissemination of oligodendroglioma is very rare. We report the case of a 38-year-old Caucasian male who presented with acute hydrocephalus. 8 months before, the patient had undergone craniotomy for right frontal anaplastic oligodendroglioma, WHO grade III. By that time, there was no evidence of tumor dissemination. MRI now ruled out local tumor progression but revealed meningeal contrast enhancement along the medulla, the myelon, and the cauda equina. Repeated lumbar puncture revealed increased cerebro-spinal fluid (CSF) pressure and protein content. Malignant cells were not detectable. Surgical treatment consisted in (1) placement of an ommaya reservoir for daily CSF puncture, (2) Spinal dural biopsy confirming leptomeningeal oligodendroglioma metastasis, and (3) ventriculo-peritoneal shunt placement after CSF protein has decreased to 1500–2000 mg/l.

    Hypoparathyroidism is the most common cause of symmetric calcification of the basal ganglia. Herein, a case of primary hypoparathyroidism with severe tetany, rhabdomyolysis, and acute kidney injury is presented. A 26-year-old male was admitted to the emergency clinic with leg pain and cramps, nausea, vomiting, and decreased amount of urine. He had been treated for epilepsy for the last 10 years. He was admitted to the emergency department for leg pain, cramping in the hands and legs, and agitation multiple times within the last six months. He was prescribed antidepressant and antipsychotic medications. He had a blood pressure of 150/90 mmHg, diffuse abdominal tenderness, and abdominal muscle rigidity on physical examination. Pathological laboratory findings were as follows: creatinine, 7.5 mg/dL, calcium, 3.7 mg/dL, alanine transaminase, 4349 U/L, aspartate transaminase, 5237 U/L, creatine phosphokinase, 262.000 U/L, and parathyroid hormone, 0 pg/mL. There were bilateral symmetrical calcifications in basal ganglia and the cerebellum on computerized tomography. He was diagnosed as primary hypoparathyroidism and acute kidney injury secondary to severe rhabdomyolysis. Brain calcifications, although rare, should be considered in dealing with patients with neurological symptoms, symmetrical cranial calcifications, and calcium metabolism abnormalities. PMID:27034860

    To evaluate patients' adherence to evidence-based therapies at an average of 2 years after discharge for Acute Coronary Syndrome (ACS) and to identify factors associated with non-adherence. This study was conducted at Hospital Pulau Pinang, Malaysia. A random sample of ACS patients (n=190) who had discharged on a regimen of secondary preventive medications were included and followed up over a three follow-up appointments at 8, 16, and 23 months post discharge. At each appointment, patients were interviewed and given Morisky questioner to complete in order to compare their level of adherence to the prescribed regimens across the three consecutive time periods. Majority of patients reported either medium or low adherence across the three time periods with only small portion reported high adherence. Furthermore, there was a significant downward trend in the level of adherence to cardio protective medications during the study period (p<0.001). This study also identified 6 factors-age, gender, employment status, ACS subtype, number of co morbidities and number of prescription medications per day that may influence Patients' adherence to their medications. Our findings suggest that long-term adherence to secondary prevention therapies among patients with ACS in Malaysia is sub optimal and influenced by many demographic, social as well as clinical factors.

    We report the case of an 11-year-old female with acute pancreatitis, and review the literature highlighting the presenting symptoms and signs, laboratory tests, and investigational tools that helped in the establishment of a correct diagnosis. First, the patient presented to a regional hospital reporting abdominal pain, vomiting and liquid stool. She was admitted with the diagnosis of acute surgical abdomen and underwent surgery. Upon admission in our department, laboratory findings showed high values for total lipids = 2600 mg/dL and triglycerides 1200 mg/dL. Abdominal ultrasound revealed a pancreas with a small enlargement of the head (19 mm), and with a heterogeneous structure of the parenchyma. Abdominal computed tomography showed small left pleural collection and a high-dimensioned pancreas, particularly at the head, with heterogeneous structure, and peripancreatic collections. The patient was treated by fasting, gastric decompression by nasogastric tube, and intravenous antibiotherapy followed by antialgic and antispasticity treatment. Time of the patient’s first feeding was after the 7th day of hospitalization. The patient was discharged in a very good condition after 22 days of hospitalization. PMID:23599811

    A combination of acute urinary retention and aseptic meningitis has occasionally been described, which is referred to as meningitis-retention syndrome. In contrast, acute urinary retention has rarely been reported in bacterial meningitis. We herein report a case of Streptococcus pneumoniae meningitis presenting with acute urinary retention which led to emphysematous cystitis in an elderly woman. She presented with impaired consciousness and a distended lower abdomen. She was diagnosed with pneumococcal meningitis by lumbar puncture. Abdominal computed tomography revealed the presence of emphysematous cystitis. She completely recovered with antibiotic therapy without any complications. Acute urinary retention can occur secondary to pneumococcal meningitis. PMID:27477423

    In the past 3 decades, a better understanding of the pathophysiology of cardiovascular disease has resulted in innovations in the treatment and prevention of its clinical manifestations such as death, myocardial infarction, or stroke. After an acute coronary syndrome there are short- and long-term risks of subsequent cardiovascular events. This leads to opportunities to initiate strategies to reduce complications resulting from myocardial injury (cardiac protection) and to prevent recurrent acute coronary events (vascular protection). The results from clinical trials inform best practice and guidelines for patient management. Despite clear and consistent guidelines, an important number of patients are not receiving these treatments. Moreover, many others do not receive treatment that follows the strategy proven in the clinical trial and this is associated with a significant loss of opportunities to improve outcomes. The Canadian Heart Research Centre has therefore assembled a panel of experts to provide a review of available data and distill it to specific evidence-based recommendations that can be used by specialists and primary care physicians as a platform for secondary prevention. The therapeutic recommendations are conveniently divided into vascular protection (dual antiplatelet therapy, lipid-lowering, and renin angiotensin system inhibition) which should be considered in all patients; cardiac protection (addition of β-blocker therapy) in patients with left ventricular dysfunction including consideration for management of heart failure; and continuing management of risk factors and comorbid conditions on the basis of the specific patient profile. These recommendations are intended as a decision support tool and a quick reference for Canadian physicians. PMID:27342696

    The incidence and nature of acute secondary irradiation esophagitis was studied in a series of 38 patients undergoing 60Co teletherapy for carcinoma of the lung. Thirty-four patients were male and four female, with ages ranging from 38 to 78 years. The mediastinum being irradiated in the process, all the patients underwent endoscopy for signs of esophagitis and/or gastritis after a dose of 30-40 Gy was delivered to the esophagus. Eighteen patients complained of dysphagia, but only in 12 of them did endoscopy show esophagitis. Of the remaining patients without complaints five had endoscopic signs of esophagitis. Gastritis was found in 18 cases and confirmed histologically in 14. In 17 cases, esophagitis and/or gastritis were confirmed histologically. It is believed that there is a fairly close correlation among clinical, endoscopic, and histological findings to support the claim that esophagitis in these patients is radiation induced. However, the cause of gastritis is not well understood. Data in the literature suggest that nonsteroid anti-inflammatory agents can act as prophylactic means of preventing radiation esophagitis.

    A 27-year-old woman was admitted to our ICU with acute hypoxemic respiratory failure and criteria for ARDS. Despite an F(IO(2)) of 1.0 and a lung protective strategy, the patient died on day 15 without any improvement. The relatives gave consent for post-mortem analysis. The histopathologic study of the lung showed findings typical of an acute fibrinous and organizing pneumonia. Apropos of this case we performed a PubMed search. We found 13 articles, including a total of 29 patients. Acute fibrinous and organizing pneumonia is an unusual cause of acute lung injury. The diagnostic criterion is histopathologic. There is little information regarding the pathophysiology of this illness. Important questions remain regarding this disease, including predisposing factors and management. Patients who require mechanical ventilation have poor outcomes.

The damaging nature of the projectile, the nature of the damage and the combination with damage to other body parts were studied. The anesthesiologist--resuscitator and surgeon actions after hospitalisation of injured persons were postulated. The emergency victim examination was reduced to ultrasound and SCT. The indications for laparotomy in abdominal gunshot injuries were defined. Three most common variants of gunshot abdomen injuries were found. In surgical treatment we applied "damage control" strategy included the initial (abbreviated) operation, resuscitative therapy and final operation. The postoperative complications, couse of deaths was investigated.

  18. Cholestatic jaundice, acute kidney injury and acute pancreatitis secondary to the recreational use of methandrostenolone: a case report

    PubMed Central

    2011-01-01

    Introduction Over the last few years the use of anabolic steroids has become increasingly common amongst amateur athletes and for aesthetic purposes. As a result, the adverse events related to their use are being seen more frequently. Methandrostenolone is an anabolic steroid which is widely available and has been used for both performance enhancement and aesthetic purposes. This drug has also been reported to cause cholestasis of the intra-hepatic bile ducts resulting in elevated aminotransferases, hyperbilirubinemia and clinical jaundice. However, to the best of our knowledge this agent has not been previously reported to cause pancreatitis or acute kidney injury. Case presentation In this paper, we report the case of a 50-year-old man of Indian descent who presented with a six week history of diffuse abdominal pain, anorexia and weight loss following an eight week cycle of methandrostenolone use. At initial presentation, his lipase level was 785 U/L, bilirubin was 922 μmol/L and creatinine was 200 U/L while his aspartate aminotransferase and alanine aminotransferase levels were only mildly elevated at 61 U/L and 56 U/L respectively. His lipase peaked on day nine at >3000 U/L whilst his creatinine level was 299 U/L. Imaging was consistent with acute pancreatitis while a liver biopsy was consistent with intra-hepatic cholestasis and a kidney biopsy revealed evidence of acute tubular necrosis. Conclusion Both acute pancreatitis and acute kidney injury have rarely been reported with anabolic steroid use and they have not been previously reported to occur in the same patient. This case demonstrates some potentially new and serious adverse consequences occurring with the use of anabolic steroids, of which physicians need to be aware. PMID:21470406

He was found to have pneumatosis intestinalis on computerized axial tomography scan of the abdomen. He underwent emergent explorative laparotomy, which revealed a necrotic large bowel segment for which a right-sided hemicolectomy and ileostomy were performed. The patient subsequently developed septic shock and hypoxic respiratory failure. He expired a week after the surgical procedure. Acute abdominal events due to vascular catastrophes secondary to hypercoagulability, endothelial dysfunction and accelerated atherosclerosis have been reported in HIV positive patients.

    Compressive myopathy syndrome (SCM) is a syndrome characterized by the lesion of skeletal muscle resulting in subsequent release of intracellular contents (myoglobin, creatine phosphokinase, potassium, etc.) into the circulatory system, which can cause potentially lethal complications. There are numerous causes that can lead to SCM resulting to acute rhabdomyolysis, and many patients present with multiple causes. The most common potentially lethal complication is acute renal failure. The occurrence of acute rhabdomyolysis should be considered as a possibility in any patient who can remain stationary for long periods, or is in a coma, or is intoxicated in any form. We report the rare case of a 26-year-old patient who developed SCM caused by ischemia reperfusion, with subsequent acute rhabdomyolysis and acute renal failure after prolonged compression of the right upper extremity.

    Causes of a massive elevation in serum aminotransferases (aspartate aminotransferase [AST] and alanine aminotransferase [ALT]) in the substance-abusing patient include viral hepatitis and drug hepatotoxicity. A patient chronically addicted to injection heroin and cocaine presented to the emergency room in a confused state and was admitted to a medical ward with an AST of 4120 U/L, ALT 3820 U/L and right upper quadrant discomfort. Investigations for viral and hepatotoxic causes for the liver dysfunction revealed only hepatitis C seropositivity. A computed tomogram of the abdomen, however, revealed a significant contusion to the right lobe of the liver consistent with traumatic injury. A motor vehicle accident, in which the patient was wearing a seat belt, and which had occurred a few days before admission and had been thought to be minor, was the cause of the liver dysfunction. Significant blunt abdominal traumatic injuries are usually managed exclusively by surgical trauma units. This case underlines the need for medical specialists to be aware of hepatic contusion injuries and to have a high index of suspicion when investigating unexplained hepatocellular dysfunction in chronic substance abusers who have been in motor vehicle accidents.

    There are some reports of renal vein thrombosis associated with acute pyelonephritis, but a case of renal artery thrombosis in acute pyelonephritis has not been reported yet. Here we report a case of renal artery thrombosis which developed in a patient with acute pyelonephritis complicated with sepsis-induced disseminated intravascular coagulation (DIC). A 65-year-old woman with diabetes was diagnosed with acute pyelonephritis complicated with sepsis. Escherichia coli was isolated from both blood and urine cultures. When treated with antibiotics, her condition gradually improved. She suddenly complained of severe right flank pain without fever in the recovery phase. A computed tomography scan revealed right renal artery thrombosis with concomitant renal infarction. Prophylactic anticoagulation therapy was not suggested because of sustained thrombocytopenia and increased risk of bleeding. Flank pain resolved with conservative treatment and perfusion of infarcted kidney improved at the time of discharge. To our knowledge, this is the first case of renal artery thrombosis related to acute pyelonephritis with sepsis-induced DIC. PMID:26889428

    Acute catecholamine cardiomyopathy is an uncommon, life-threatening manifestation of pheochromocytoma. The massive release of catecholamines from the adrenal medulla and their toxic effects on the coronary vessels and the cardiac myocytes play a significant role in the pathogenesis of cardiomyopathy in patients with pheochromocytoma. Severe manifestations, such as acute catecholamine cardiomyopathy, may be the initial presentation, especially in unsuspected and untreated pheochromocytoma cases. The clinical course of catecholamine-induced cardiomyopathy is unpredictable as patients may rapidly deteriorate into circulatory collapse and multisystem crisis. We report a case of a 25-year-old man who presented with catecholamine-induced cardiomyopathy. PMID:26512333

    Occipital lobe infarction secondary to tentorial herniation is a rare but well-recognized complication of posterior cerebral artery interruption during acute hydrocephalus; however, a similar event in which tonsillar herniation leads to symptomatic occlusion of the anterior spinal arteries (ASAs) has not been reported. The authors present the case of a third ventricular colloid cyst in a previously healthy 24-year-old man who presented with symptoms and signs of critically raised intracranial pressure. He subsequently survived the ictus of insults following emergency external cerebrospinal fluid drainage and definitive resection of the colloid cyst, but he sustained occipital lobe and spinal cord infarction despite the absence of systematic hypotension. The presence of watershed cervicothoracic cord infarction on magnetic resonance imaging suggested that the most likely causes were compromise of ASAs during the period of acute hydrocephalus and the accompanying downward brain herniation. To the authors' knowledge, this is the first report to provide evidence that acute hydrocephalus may lead to ASA syndrome.

    Acute respiratory distress syndrome (ARDS) continues to have significant mortality and morbidity. The only intervention proven to reduce mortality is the use of lung-protective mechanical ventilation strategies, although such a strategy may lead to problematic hypercapnia. Extracorporeal carbon dioxide removal (ECCO₂R) devices allow uncoupling of ventilation from oxygenation, thereby removing carbon dioxide and facilitating lower tidal volume ventilation. We performed a systematic review to assess efficacy, complication rates, and utility of ECCO₂R devices. We included randomised controlled trials (RCTs), case-control studies and case series with 10 or more patients. We searched MEDLINE, Embase, LILACS (Literatura Latino Americana em Ciências da Saúde), and ISI Web of Science, in addition to grey literature and clinical trials registries. Data were independently extracted by two reviewers against predefined criteria and agreement was reached by consensus. Outcomes of interest included mortality, intensive care and hospital lengths of stay, respiratory parameters and complications. The review included 14 studies with 495 patients (two RCTs and 12 observational studies). Arteriovenous ECCO₂R was used in seven studies, and venovenous ECCO₂R in seven studies. Available evidence suggests no mortality benefit to ECCO₂R, although post hoc analysis of data from the most recent RCT showed an improvement in ventilator-free days in more severe ARDS. Organ failure-free days or ICU stay have not been shown to decrease with ECCOvR. Carbon dioxide removal was widely demonstrated as feasible, facilitating the use of lower tidal volume ventilation. Complication rates varied greatly across the included studies, representing technological advances. There was a general paucity of high-quality data and significant variation in both practice and technology used among studies, which confounded analysis. ECCO₂R is a rapidly evolving technology and is an efficacious treatment

It also discusses the advantages and disadvantages of the different imaging techniques that can be used to guide these procedures (ultrasound, CT, and fluoroscopy) as well as the possible complications that can develop from each procedure. Finally, it shows the importance of following up patients clinically and of taking care of catheters.

    Tuberculosis, in its various forms, remains an important cause of morbidity and mortality in developing countries in immunodeficitary patients. The indicatives of epidemiology of tuberculosis show that Romania presents a fresh outbreak of the disease in the last few years. The purpose of this paper is to present from the various forms of extrapulmonary tuberculosis, the intestinal tipe which have a high incidence. The authors describe theirs preliminary experience of intraoperative small and large bowel emergencies resections in a short period (1 year) of three young patients (between 30 and 40 years old) with history of pulmonary tuberculosis. The pathology was complex (bowel obstructions, peritonitis) and so were the surgical operations (resections, devirations). The patients showed short and long term good results.

    Nonostante i significativi vantaggi della chirurgia laparoscopica rispetto a quella laparotomica, essa era considerata controindicata per le donne gestanti. Attualmente si confrontano opinioni contrastanti riguardo alla sicurezza durante la gestazione della chirurgia laparoscopica, specie se nell’ultimo trimestre. Lo scopo di questo studio è quello di valutare la fattibilità della chirurgia laparoscopica in donne gestanti in caso di addome acuto analizzando retrospettivamente la casistica della pazienti ricoverate tra il gennaio 1995 ed il gennaio 2013 presso l’Emergency Department della Cerrahpasa Medical Faculty. Sono stati pertanto analizzati tutti i dati clinici riguardanti le gestanti sottoposte a chirurgia laparoscopica, comprese le cartelle cliniche, gli interventi eseguiti, i reperti anatomopatologici, e le informazioni riguardanti il parto. Nella casistica sono rientrate 14 donne gravide (in media alla 19,2° settimana di gestazione, distribuite tra 9 e 33 settimane), di cui 11 sottoposte ad appendicectomia laparoscopica, 2 a colecistectomia laparoscopica ed 1 per scopi diagnostici. In media il parto si è espletato alla 37,4° settimana di gestazione (tra la 35° e la 40° settimana). Due pazienti hanno avuto un parto prematuro, ma in nessune dei casi si sono verificate complicazioni durante le manovre laparoscopiche, e cioè danni all’utero, morti fetali o mortalità materna. Si conclude che la chirurgia laparoscopica può essere effettuata nel corso di tutti i trimestri della gravidanza, con il possibile vantaggio di una utile diagnosi differenziale in caso di dolori addominali acuti durante la gravidanza, e diminuzioni delle morti fetali dovute a ritardi diagnostici, e che tempi chirurgici più brevi riducono gli effetti negativi sulla madre e sul feto.

    Gastric duplication cysts are rare variety of gastrointestinal duplications. Sometimes they may present with complications like hemorrhage, infection, perforation, volvulus, intussusception and rarely neoplastic changes in the gastric duplication cyst. We present one and half year old male child who developed sudden abdominal distension with pain and fever for two days. Ultrasound revealed a cystic mass in the hypochondrium and epigastric regions. On exploration an infected and perforated gastric duplication cyst was found. Surgical excision of most part of cyst wall with mucosal stripping of the rest was performed. Histopathology confirmed the diagnosis of gastric duplication cyst. Early surgical intervention can result in good outcome. PMID:22953249

    Interstitial lung diseases belong to a group of diseases that typically exhibit a subacute or chronic progression but that may cause acute respiratory failure. The male patient, who was 37 years of age and undergoing therapy for non-Hodgkin's lymphoma, was admitted with cough, fever, dyspnea and acute hypoxemic respiratory failure. Mechanical ventilation and antibiotic therapy were initiated but were associated with unfavorable progression. Thoracic computed tomography showed bilateral pulmonary "ground glass" opacities. Methylprednisolone pulse therapy was initiated with satisfactory response because the patient had used three drugs related to organizing pneumonia (cyclophosphamide, doxorubicin and rituximab), and the clinical and radiological symptoms were suggestive. Organizing pneumonia may be idiopathic or linked to collagen diseases, drugs and cancer and usually responds to corticosteroid therapy. The diagnosis was anatomopathological, but the patient's clinical condition precluded performing a lung biopsy. Organizing pneumonia should be a differential diagnosis in patients with apparent pneumonia and a progression that is unfavorable to antimicrobial treatment. PMID:23917942

    A 29-year old female presented with a one-week history of vomiting, diarrhoea, abdominal pain, and headache. On admission, she had acute renal failure requiring dialysis. Tests revealed a hemolytic anemia with thrombocytopenia. An initial diagnosis of thrombotic thrombocytopenic microangiopathy was made and plasma exchange was instigated. However, renal biopsy did not show thrombotic microangiopathy but instead revealed acute kidney injury with mild tubulointerstitial nephritis and numerous oxalate crystals, predominantly in the distal tubules. The patient had been taking large doses (>1100 mg daily) of vitamin C for many months. She also gave a history of sclerotherapy using injections of an ethylene glycol derivative for superficial leg veins. The patient completed five sessions of plasma exchange and was able to discontinue dialysis. She eventually achieved full renal recovery. She has now discontinued sclerotherapy and vitamin supplementation. PMID:21785726

    A 78-year-old man, with a 6-year history of stable chronic myelomonocytic leukaemia (CMML), presented with general deterioration and worsening pancytopenia. Bone marrow biopsy showed that his disease had transformed into acute myeloid leukaemia (AML). He was started on a supportive transfusion regimen and did not receive any chemotherapy or corticosteroids. Several weeks later, he developed acute renal failure and was admitted to a medical admissions ward. Spontaneous tumour lysis syndrome (sTLS, grade 1) was diagnosed, as per the Cairo and Bishop criteria. He was treated with intravenous fluids, rasburicase and allopurinol. His renal function improved and he recovered from the sTLS. The authors believe that this is the first published case of sTLS occurring as a result of CMML transforming into AML; it highlights the importance of recognising sTLS as a cause of renal failure and electrolyte disturbance before cancer treatment begins.

    Complementary and alternative medicine (CAM) use among cancer patients is widely prevalent and often underreported. Advanced stage of disease is significantly associated with CAM use. The concurrent use of alternative medicines and chemotherapy drugs has the potential to lead to toxicities as well as altered therapeutic activity due to unknown interactions. We report a case of early breast cancer who presented to us with non-oliguric acute renal failure related concurrent use of Ayurvedic medicines and adjuvant anthracycline based.

    Patients with multifocal epilepsy are often considered unsuitable for epilepsy surgery. We report an adolescent with intractable frontal and occipital lobe seizures, secondary to complications of treatment for acute lymphoblastic leukaemia as a young child. Chemotherapy and radiotherapy were complicated by bilateral, posterior leukoencephalopathy and later an acquired frontal cerebral cavernous malformation (CCM). Detailed electro-clinical and imaging studies showed multiple, frontal lobe seizures per day with less frequent and non-debilitating, simple, occipital lobe seizures. Focal resection of the frontal CCM abolished the socially-disabling seizures with resultant marked improvement in the patient's quality of life at 12 months. Careful analysis of the type and impact of focal seizures in the setting of multifocal epilepsy may demonstrate that one seizure type is more deleterious to quality of life and may be amenable to surgery. In this situation, the patient may benefit significantly from surgery to resect the more active epileptic focus.

    Complete congenital absence of the omentum is very rare with only one previously reported case. We present a unique case of the management of a pregnant woman with a large pelvic pseudocyst caused by complications related to congenital absence of omentum, resulting in acute kidney injury, likely secondary to acute compartment syndrome. This case highlights the importance of considering acute compartment syndrome in critically unwell pregnant women and reiterates the need to measure intra-abdominal pressure when clinically indicated. Given that pregnancy is in itself a state of intra-abdominal hypertension, obstetricians should maintain a high index of suspicion in the context of additional risk factors. PMID:27630753

    Lung cancer is one of the most frequent neoplasms. The symptoms are due to the cancer itself, its extension, and associated paraneoplastic syndromes. Although biliopancreatic metastases are common, biliopancreatic involvement as the initial symptom of lung cancer--whether as pancreatitis or obstructive jaundice--is rare. We describe our clinical experience, reporting two patients with acute pancreatitis and one patient with obstructive jaundice as the clinical presentation of advanced lung cancer. We also provide a brief review that highlights the absence of guidelines in this situation.

    We present a typical case of acute suppurative thyroiditis (AST), associated with a piriform sinus fistula. We illustrate the case with an ultrasound picture of a hypoechogenic perithyroid mass and a CT scan using intravenous iodine contrast showing a perithyroid hypodense mass with peripheral enhancement, the mass also having intrathyroid involvement. When clinical and radiological findings suggest the presence of AST, it is necessary to rule out the presence of a piriform sinus fistula by means of a radiological study with barium contrast. Piriform sinus fistula is a rare abnormality derived from the branchial arch which is directly related to recurrent episodes of AST; surgical excision is hence, necessary to avoid such episodes.

    Background and objectives: Extended hemodialysis using a high cut-off dialyzer (HCO-HD) removes large quantities of free light chains in patients with multiple myeloma. However, the clinical utility of this method is uncertain. This study assessed the combination of chemotherapy and HCO-HD on serum free light chain concentrations and renal recovery in patients with myeloma kidney (cast nephropathy) and dialysis-dependent acute renal failure. Design, setting, participants, & measurements: An open-label study of the relationship between free light chain levels and clinical outcomes in 19 patients treated with standard chemotherapy regimens and HCO-HD. Results: There were sustained early reductions in serum free light chain concentrations (median 85% [range 50 to 97]) in 13 patients. These 13 patients became dialysis independent at a median of 27 d (range 13 to 120). Six patients had chemotherapy interrupted because of early infections and did not achieve sustained early free light chain reductions; one of these patients recovered renal function (at 105 d) the remaining 5 patients did not recover renal function. Patients who recovered renal function had a significantly improved survival (P < 0.012). Conclusion: In dialysis-dependent acute renal failure secondary to myeloma kidney, patients who received uninterrupted chemotherapy and extended HCO-HD had sustained reductions in serum free light chain concentrations and recovered independent renal function.

    Pure erythroid leukaemia is a rare subtype of acute myeloid leukaemia (AML) and its occurrence at acute lymphoblastic leukaemia (ALL) relapse has not been reported earlier. A 39-year-old man received chemotherapy for Philadelphia-negative B cell ALL. Subsequently, he developed pure erythroid leukaemia with >80% immature erythroid precursors in bone marrow showing block positivity on periodic acid-Schiff stain, expressing CD71, CD34 but lacking CD235a. The interval between exposure to multidrug chemotherapy including cyclophosphamide and AML diagnosis was 2 years and 9 months. No cytogenetic abnormality was detected at the time of relapse. The patient died 2 weeks after starting AML chemotherapy. The relatively narrow time interval (usually 5-10 years) between chemotherapy and AML development and normal karyotype at relapse raises a possibility of lineage switch besides therapy-related AML as the likely pathogenesis. Further exploration of such cases may unravel the pathways responsible for lineage assignment in pluripotent stem cells.

He had no other significant past medical history. The child was shifted to nearby health facility where he was managed as a case of acute abdomen on the basis of suggestive history and clinical findings. Within 2 h after the onset of clinical features suggestive of acute abdomen the patient went on to develop marked ptosis and flaccid quadriplegia. The young boy underwent a sequence of clinical tests which were noncontributory. Based on the clinical picture, a differential diagnosis of hypokalemic paralysis, botulism, Miller Fischer syndrome and EMNS were considered. Through exclusion, the most probable diagnosis for the symptoms was elapid envenomation hence he was started on anti-snake venom (ASV) with working diagnosis of EMNS. Within 2 h, he began to show improvement. This recovery with ASV suggests the possibility of elapid envenomation.

    Five stocks of Drosophila buzzatii with superficially similar abdominal disruptions including partial tergite and sternite loss were isolated by inbreeding. Three of the stocks have indistinguishable phenotypes, the inheritance of which is maternally influenced. This phenotype and its mode of inheritance bear similarities with those of Abnormal abdomen in D. melanogaster. The phenotype in the fourth stock is slightly different and is due to a single autosomal recessive gene, which we denote incomplete abdomen. In the fifth stock the trait is limited to females, and in appearance and mode of inheritance resembles bobbed in D. melanogaster. Furthermore, only in this stock are rDNA deletions evident. The combined frequencies of the three types of abdominal aberration were found to be around 1% in several samples from wild and laboratory populations of D. buzzatii. PMID:2620817

    1994-12-01

    Folic acid-induced acute renal injury results in dramatic changes in gene expression. Among the genes affected by folic acid treatment are the primary response genes, c-fos and c-myc, which are thought to function to initiate cell cycle events. In this report, changes in the expression of three other genes in response to folic acid injury have been investigated: ornithine decarboxylase, epidermal growth factor (EGF), and sulfated glycoprotein-2 (SGP-2). Renal injury was found to cause a rapid decrease in EGF mRNA, which remained absent for several days after the initial injury, gradually returning to normal levels over an approximately 3-wk regeneration and recovery period. Ornithine decarboxylase mRNA showed a similar decrease. In contrast, folic acid caused a rapid increase in SGP-2 mRNA, which peaked several days after treatment, decreasing to normal levels over the 3-wk period. The mRNAs for the primary response genes were superinduced in the injured kidneys in the presence of the protein synthesis inhibitor cycloheximide. In contrast, the changes in EGF and SGP-2 mRNA levels were blocked by cycloheximide, indicating that these responses required new protein synthesis during the first few hours after folic acid injury. The opposite but parallel responses in the expression of the EGF and SGP-2 genes suggest that their regulation is coupled to the initial injury-induced dedifferentiation and subsequent return to the fully differentiated state.

    Leukostasis is a relatively uncommon but potentially catastrophic complication of acute myelogenous leukemia (AML). Prompt leukoreduction is considered imperative to reduce the high mortality rate in this condition. Leukapheresis, usually associated with chemotherapy, is an established approach to diminish blast cell counts. We report a single center experience in managing leukostasis with leukapheresis. Fifteen patients with leukostasis of 187 patients with AML (8.02%) followed at our institution were treated with leukapheresis associated with chemotherapy. The procedures were scheduled to be performed on a daily basis until clinical improvement was achieved and WBC counts were significantly reduced. Overall and early mortalities, defined as that occurred in the first 7 days from diagnosis, were reported. A high proportion of our patients with leukostasis (46.66%) had a monocytic subtype AML (M4/M5, according to French-American-British classification). The median overall survival was 10 days, despite a significant WBC reduction after the first apheresis procedure (from 200.7 × 10⁹/L to 150.3 × 10⁹/L). Almost half of patients (7/15) had an early death. Therapeutic leukapheresis, associated or not to chemotherapy, is an effective approach to reduce WBC counts in patients with AML and leukostasis; however, this therapeutic procedure does not appear to change significantly the sombre prognosis observed in the majority of patients with this complication. Other forms of treatment must be found to reduce the high mortality rate related to leukostasis.

    Acute pancreatitis (AP) is a frequent and potentially life-threatening disease with high morbidity and mortality. The overall mortality of AP is approximately 5%. Alcohol consumption and gallstones are the main etiology of AP. Hypertriglyceridemia, idiosyncratic reactions to drugs, anatomic alterations and ascaris lumbricoides can also give rise to AP. Although spinal cord injury (SCI) can cause AP, however, the case of induced by cervical spine surgery has not been reported. A 61-year-old man with quadriplegic and respiratory distress received cervical spine surgery for spinal cervical spondylosis and multi-stage longitudinal ligament. He was admitted to intensive care unit (ICU) after tracheotomy for progressive dyspnea, one day after the cervical spine surgery. The patient was diagnosed with AP, in the absence of any identifiable causes of pancreatitis. He was treated with intravenous fluids, no oral feeding, enteral and parenteral nutrition, antibiotic and mechanical ventilation. The patient's condition gradually improved after the treatment. This case describes a case of postoperative cervical spondylosis that led to AP. In this report, we highlight the importance of early diagnosis and subsequent appropriate treatment. We conclude that the outcome can be favorable, if the treatment is appropriate. PMID:26707037

    Dragonflies are able to achieve fast turning maneuvers during take-off flights. Both asymmetric wing flapping and abdomen flexion have been observed during the fast turning. It's widely thought that the asymmetric wing beats are responsible of producing the aerodynamic moment needed for the body rotation. However, the dynamic effect of the abdomen flexion is not clear yet. In this study, an integrated experimental and computational approach is used to study the underlying dynamic effect of dragonfly abdomen flexion. It's found that dragonfly abdomen tended to bend towards the same side as the body reorienting to. Quantitative analysis have shown that during take-off turning maneuver the abdomen flexion can modulate the arm of force by changing the position of the center of mass relative to the thorax. As a result, roll and yaw moments produced by the wing flapping can be enhanced. This work is supported by NSF CBET-1313217. This work is supported by NSF CBET-1313217.

    Acute kidney injury induced by renal ischemia-reperfusion (I/R) compromises microvascular density and predisposes to chronic kidney disease (CKD) and sodium-dependent hypertension. VEGF-121 was administered to rats fed a standard (0.4%) sodium diet at various times following recovery from I/R injury for up to 35 days. VEGF-121 had no effect on the initial loss of renal function, as indicated by serum creatinine levels measured 24 h after injury. Serum creatinine levels declined thereafter, indicative of renal repair. Rats were then switched to an elevated (4.0%) sodium diet for an additional 28 days to induce CKD. The 4.0% sodium diet enhanced renal hypertrophy, interstitial volume, albuminuria, and cardiac hypertrophy relative to postischemic animals maintained on the 0.4% sodium diet. Administration of VEGF-121 from day 0 to 14, day 0 to 35, or day 3 to 35 after I/R suppressed the effects of sodium diet on CKD development, while delayed administration of VEGF-121 from day 21 to 35 had no effect. Endothelial nitric oxide synthase protein levels were upregulated in postischemic animals, and this effect was significantly increased by the 4.0% sodium diet but was not influenced by prior treatment with VEGF. Conversely, microvascular density was preserved in postischemic animals treated with VEGF-121 relative to vehicle-treated postischemic animals. These data suggest that early, but not delayed, treatment with VEGF-121 can preserve vascular structure after ischemia and influence chronic renal function in response to elevated sodium intake.

    Introduction The unique pharmacokinetic properties of remifentanil with a context-sensitive half-life unaffected by length of infusion contribute to its frequent use during anesthetic management during posterior spinal fusion in children and adolescents. However, its intraoperative administration can lead to increased postoperative analgesic requirements, which is postulated to be the result of acute opioid tolerance with enhancement of spinal N-methyl-D-aspartate receptor function. Although strategies to prevent or reduce tolerance have included the coadministration of longer acting opioids or ketamine, the majority of these studies have demonstrated little to no benefit. The current study retrospectively evaluates the efficacy of intrathecal morphine (ITM) in preventing hyperalgesia following a remifentanil infusion. Methods We retrospectively analyzed 54 patients undergoing posterior spinal fusion with segmental spinal instrumentation, to evaluate the effects of ITM on hyperalgesia from remifentanil. Patients were divided into two groups based on whether they did or did not receive remifentanil during the surgery: no remifentanil (control group) (n=27) and remifentanil (study group) (n=27). Data included demographics, remifentanil dose and duration, Wong–Baker visual analog scale postoperative pain scores, and postoperative intravenous morphine consumption in the first 48 postoperative hours. Results The demographics of the two study groups were similar. There were no differences in the Wong–Baker visual analog scale pain scores in the postanesthesia care unit and on postoperative days 1 and 3. Pain scores were higher in the remifentanil group on postoperative day 2 (2.9 vs 3.8). Postoperative morphine requirements were similar between the two groups (0.029 vs 0.017 mg/kg/48 h for the control group and the study group, respectively). Conclusion In patients receiving preincisional ITM during spinal surgery, intraoperative remifentanil does not increase

    Clonal architecture in myeloproliferative neoplasms (MPNs) is poorly understood. Here we report genomic analyses of a patient with primary myelofibrosis (PMF) transformed to secondary acute myeloid leukemia (sAML). Whole genome sequencing (WGS) was performed on PMF and sAML diagnosis samples, with skin included as a germline surrogate. Deep sequencing validation was performed on the WGS samples and an additional sample obtained during sAML remission/relapsed PMF. Clustering analysis of 649 validated somatic single nucleotide variants revealed four distinct clonal groups, each including putative driver mutations. The first group (including JAK2 and U2AF1), representing the founding clone, included mutations with high frequency at all three disease stages. The second clonal group (including MYB) was present only in PMF, suggesting the presence of a clone that was dispensable for transformation. The third group (including ASXL1) contained mutations with low frequency in PMF and high frequency in subsequent samples, indicating evolution of the dominant clone with disease progression. The fourth clonal group (including IDH1 and RUNX1) was acquired at sAML transformation and was predominantly absent at sAML remission/relapsed PMF. Taken together, these findings illustrate the complex clonal dynamics associated with disease evolution in MPNs and sAML. PMID:25252869

    The atonal (ato) proneural gene specifies a stereotypic number of sensory organ precursors (SOP) within each body segment of the Drosophila ectoderm. Surprisingly, the broad expression of Ato within the ectoderm results in only a modest increase in SOP formation, suggesting many cells are incompetent to become SOPs. Here, we show that the SOP promoting activity of Ato can be greatly enhanced by three factors: the Senseless (Sens) zinc finger protein, the Abdominal-A (Abd-A) Hox factor, and the epidermal growth factor (EGF) pathway. First, we show that expression of either Ato alone or with Sens induces twice as many SOPs in the abdomen as in the thorax, and do so at the expense of an abdomen-specific cell fate: the larval oenocytes. Second, we demonstrate that Ato stimulates abdominal SOP formation by synergizing with Abd-A to promote EGF ligand (Spitz) secretion and secondary SOP recruitment. However, we also found that Ato and Sens selectively enhance abdominal SOP development in a Spitz-independent manner, suggesting additional genetic interactions between this proneural pathway and Abd-A. Altogether, these experiments reveal that genetic interactions between EGF-signaling, Abd-A, and Sens enhance the SOP-promoting activity of Ato to stimulate region-specific neurogenesis in the Drosophila abdomen.

    Background Clopidogrel’s effectiveness is likely reduced significantly for prevention of thrombotic events after acute coronary syndrome (ACS) in patients exhibiting a decreased ability to metabolize clopidogrel into its active form. A genetic mutation responsible for this reduced effectiveness is detectable by genotyping. Ticagrelor is not dependent on gene-based metabolic activation and demonstrated greater clinical efficacy than clopidogrel in a recent secondary prevention trial. In 2011, clopidogrel will lose its patent protection and likely will be substantially less expensive than ticagrelor. Objective To determine the cost-effectiveness of ticagrelor compared with a genotype-driven selection of antiplatelet agents. Methods A hybrid decision tree/Markov model was used to estimate the 5-year medical costs (in 2009 US$) and outcomes for a cohort of ACS patients enrolled in Medicare receiving either genotype-driven or ticagrelor-only treatment. Outcomes included life years and quality-adjusted life years (QALYs) gained. Data comparing the clinical performance of ticagrelor and clopidogrel were derived from the Platelet Inhibition and Patient Outcomes trial. Results The incremental cost-effectiveness ratio (ICER) for universal ticagrelor was $10,059 per QALY compared to genotype-driven treatment, and was most sensitive to the price of ticagrelor and the hazard ratio for death for ticagrelor compared with clopidogrel. The ICER remained below $50,000 per QALY until a monthly ticagrelor price of $693 or a 0.93 hazard ratio for death for ticagrelor relative to clopidogrel. In probabilistic analyses, universal ticagrelor was below $50,000 per QALY in 97.7% of simulations. Conclusion Prescribing ticagrelor universally increases quality-adjusted life years for ACS patients at a cost below a typically accepted threshold. PMID:21669373

    Abdominal aortic injury as a result of blunt trauma is a rare event and has been described in few children. A 6-year-old girl presented with acute bilateral lower extremity ischemia, and a triad of acute aortic occlusion, intra-abdominal visceral injury, and a lumbar chance fracture after sustaining a seat belt injury from a motor vehicle collision. An emergency aortic thromboendarterectomy and primary repair were performed. This represents one of the few reports of acute traumatic aortic thrombosis in a child and highlights the surgical treatment of acute abdominal aortic injury in a pediatric patient.

    The authors report a new technique for secondary abdominal closure after burst abdomen as illustrated by the case of a patient who developed a perforated sigmoid diverticulitis following septic polyarthritis. Sigmoid resection was followed on the sixth day postoperative by a burst abdomen. Upon abdominal revision the burst abdomen was found to be caused by necrotic destruction of the linea alba. Abdominal wall closure was achieved using the novel technique of inverting bilateral interrupted figure-of-eight suture of the anterior and posterior rectus sheaths in combination with relieving lateral incisions and mesh implantation in the sublay technique. It remains for future studies to show whether this technique can reduce the high incisional hernia rate following secondary abdominal wall closure.

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

    Objectives: To discuss our center’s experience with acute respiratory distress syndrome (ARDS) secondary to pulmonary tuberculosis (TB) in a major tertiary referral hospital in the Kingdom of Saudi Arabia. Methods: A retrospective review of medical records of all patients with community-acquired pneumonia secondary to mycobacterium TB infection who were admitted for critical care in a single center of King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia from 2004 to 2013. Results: In our review of 350 patients with community-acquired pneumonia admitted to Intensive Care Unit, 11 cases of TB complicated with ARDS were identified. The mean age of patients was 51.9 years. The median time from hospital admission to pulmonary TB diagnosis and start of therapy was 5 days, while the median time from onset of symptoms to initiation of treatment was 18 days. The mortality rate was 64%, and the median length of hospital stay before death was 21.4 days. Delayed treatment, as well as high acute physiology and chronic health evaluation II and CURB-65 scores at presentation, were independent risk factors for death. Conclusion: Patients with pulmonary TB infrequently present to intensive care with acute symptoms that meet all criteria for ARDS. Such a presentation of TB carries a high mortality risk.

    Abdominal compartment syndrome (ACS) is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not. PMID:22606517

    "Open abdomen" is a strategy used to avoid or treat abdominal compartment syndrome. It has reduced mortality both in trauma and non-trauma abdominal catastrophes but also has created a challenging clinical problem. Traditionally, open abdomen is closed in two phases; primarily with a free skin graft and later with a flap reconstruction. A modern trend is to close the abdomen within the initial hospitalization. This requires multi-professional co-operation. Temporary abdominal closure methods, e.g. negative pressure wound therapy alone or combined with mesh-mediated traction, have been developed to facilitate direct fascial closure. Components separation technique, mesh reinforcement or bridging of the fascial defect with mesh and perforator saving skin undermining can be utilized in the final closure if needed. These techniques can be combined. Choice of the treatment depends on the condition of the patient and size of the fascia and skin defect, and the state of the abdominal contents. In this paper we review the literature on the closure of an open abdomen and present the policy used in our institution in the open abdomen situations.

    The traditional treatment of venous thromboembolism (VTE) has been use of heparin and vitamin K antagonists (VKA), and although shown to be effective, they have numerous limitations. New oral anticoagulants (NOACs) including direct thrombin (factor IIa) inhibitors (dabigatran) and selective factor Xa inhibitors (rivaroxaban, apixaban and edoxaban) have emerged as promising alternatives with the potential to overcome the limitations of traditional treatments. Clinical trials have been performed with a view to making significant changes to the acute, long-term and extended treatment of VTE. Data are now available on the efficacy and safety, including bleeding rates, of the NOACs in comparison with VKA in the acute treatment and secondary prevention of VTE as well as in comparison with placebo extended VTE treatment. This review compares and contrasts the design and results of the Phase III trials of NOACs in VTE and discusses the implications of the NOACs in terms of treatment strategies in VTE patients.

    Case records of 43 horses with pleural effusion associated with acute pleuropneumonia, chronic pleuropneumonia, or pleuritis secondary to a penetrating thoracic wound were reviewed to determine the predisposing factors, diagnosis, and treatment of this condition. Acute pleuropneumonia was diagnosed in 36 horses, the majority of which were Thoroughbreds (89%). Of 22 (61%) horses that were in race training at the onset of illness, 11 (31%) had been recently transported a long distance and 4 (11%) had evidence of exercise-induced pulmonary hemorrhage. Physical examination findings and hematologic data were nonspecific. The most consistent abnormality was hyperfibrino-genemia. Affected horses were treated with antibiotics, thoracic drainage, nonsteroidal anti-inflammatory drugs, and supportive care. Twenty-two (61%) horses were discharged from the hospital, with the mean duration of hospitalization for those discharged being 23 days. Nine (25%) horses were euthanatized and 5 (14%) died. Bacterial culturing of thoracic fluid resulted in growth in 30 of the 36 (83%) horses. The finding of anaerobic bacteria in thoracic fluid was not associated with a lower survival rate (62%) than the overall survival rate (61%). Four horses with chronic pleuropneumonia had a history of lethargy and inappetence for > 2 weeks. Actinobacillus equuli was isolated, either alone or in combination with other bacteria, from thoracic fluid of these 4 horses. Each horse was treated with broad spectrum antibiotics and made a rapid recovery. Three horses with acute pleuritis secondary to penetrating thoracic wounds also had nonspecific clinical signs, apart from the wound and a large volume of pleural effusion. Bacteriologic isolates from these horses differed slightly from those of horses with acute pleuropneumonia. PMID:7744650

    Studies have consistently shown that both consumption of acute amounts of alcohol and elevated antisocial psychopathic traits are associated with an impaired ability for prepotent response inhibition. This may manifest as a reduced ability to inhibit prepotent race biased responses. Here, we tested the effects of acute alcohol consumption, and elevated antisocial psychopathic traits, on judgments of the attractiveness and health of ethnic ingroup and outgroup faces. In the first study, we show that following acute alcohol consumption, at a dose that is sufficient to result in impaired performance on tests of executive function, Caucasian participants judged White faces to be more attractive and healthier compared to when sober. However, this effect did not extend to Black faces. A similar effect was found in a second study involving sober Caucasian participants where secondary psychopathic traits were related to an intergroup bias in the ratings of attractiveness for White versus Black faces. These results are discussed in terms of a model which postulates that poor prefrontal functioning leads to increases in ingroup liking as a result of impaired abilities for prepotent response inhibition.

    Background The Clinical Assessment Program and Teflaro® Utilization Registry is designed to collect information on the clinical use of ceftaroline fosamil in the Unites States. This report presents data on the treatment of patients with Staphylococcus aureus bacteremia (SAB) secondary to acute bacterial skin and skin structure infections (ABSSSIs) or community-acquired bacterial pneumonia (CABP). Methods Patients diagnosed with ABSSSI or CABP were identified through sequential review of randomly ordered charts generated from pharmacy listings from August 2011 to February 2013. Data were collected by chart review 30 days or more after completion of ceftaroline fosamil therapy. Results Secondary SAB was reported in a total of 48 of 1428 evaluable patients (27 with ABSSSI, 21 with CABP). The mean (SD) patient age was 61 (15) years. At least 1 comorbidity was recorded for 74% of patients with ABSSSI and 81% with CABP. Methicillin-resistant S. aureus was isolated from 59% of patients with ABSSSI and 76% with CABP. The mean (SD) duration of ceftaroline fosamil therapy was 5.8 (4.8) days for ABSSSI and 7.0 (3.8) days for CABP. Clinical success among all patients with SAB treated with ceftaroline fosamil was 58% (52% for SAB secondary to ABSSSI, 67% for SAB secondary to CABP). Clinical success rates of methicillin-resistant S. aureus SAB were 50% (8/16) for ABSSSI and 63% (10/16) for CABP. Conclusions This study supports the use of ceftaroline fosamil as a viable treatment option in hospitalized patients with SAB secondary to ABSSSI or CABP. Further studies evaluating the use of ceftaroline fosamil for the treatment of SAB are warranted. PMID:25574117

    The most common indications for an open abdomen (OA) are abdominal compartment syndrome, damage control surgery, diffuse peritonitis and wound dehiscence, and often require a temporary abdominal closure (TAC). The different TAC methods that are currently available include skin closure techniques, mesh products and negative pressure therapy (NPT) systems. For this study, we retrospectively reviewed records of 115 OA patients treated with the commercially available NPT systems (V.A.C.(®) Abdominal Dressing System and ABThera™ Open Abdomen Negative Pressure Therapy System) using a new method of applying the system - the narrowing technique - over a 5-year period. Endpoints included fascial closure and 30-day mortality rates and presence of enteroatmospheric fistulas. Secondary closure of the fascia was obtained in 92% (106/115) of the patients with a mortality rate of 17% (20/115) and a fistula rate of 3·5% (4/115). The use of the narrowing technique to apply NPT may explain the high closure rates observed in the patient population of this study. Further studies are necessary to compare the different methods and to evaluate the long-term outcomes.

    The immunosuppression following initial septic insult impairs resistance to secondary infection. Modulation of lymphocytes population may help to develop an effective therapeutic strategy. In this study, lipopolysaccharide (LPS)-induced endotoxemia was employed as the initial septic insult. 24 hours later, mice underwent cecal ligation and puncture to induce chronic or sub-acute peritonitis. Potential usefulness of T regs deletion antibody (anti-CD25) in improving LPS-induced immunosuppression and the survival of subsequent different infections were evaluated. LPS injection induced lymphocyte loss and led to decreased IL-6, TNF-α and IFN-γ, and weakened bacteria clearance upon chronic peritonitis at 24 h post-LPS, whereas reconstitution with lymphocytes reversed these changes. LPS-induced T regs expansion contributed to T and NK cells decrease in number and activity during sepsis. Depletion of T regs using anti-CD25 antibodies partly prevented lymphocyte loss and increased the responses of T and NK cells to subsequent stimulation, resulting in significantly increased bacterial clearance and survival in a 2-hit model of chronic peritonitis, but which significantly increased early mortality upon subsequently sub-acute infection. Yet, using lower dosage of anti-CD25 antibodies to moderate down-regulate T regs levels could partly improve bacterial clearance and survival in either chronic or sub-acute infection. These results demonstrate that using anti-CD25 antibodies to deplete T regs can ameliorate immunosuppression through increasing T cells and NK cells responses in sepsis, which is beneficial for preventing subsequently chronic infection, but will probably bring some deleterious effects for subsequent sub-acute infection.

    Honey bees have the ability to detect the Earth's magnetic field, and the suspected magnetoreceptors are the iron granules in the abdomens of the bees. To identify the sensing route of honey bee magnetoreception, we conducted a classical conditioning experiment in which the responses of the proboscis extension reflex (PER) were monitored. Honey bees were successfully trained to associate the magnetic stimulus with a sucrose reward after two days of training. When the neural connection of the ventral nerve cord (VNC) between the abdomen and the thorax was cut, the honey bees no longer associated the magnetic stimulus with the sucrose reward but still responded to an olfactory PER task. The neural responses elicited in response to the change of magnetic field were also recorded at the VNC. Our results suggest that the honey bee is a new model animal for the investigation of magnetite-based magnetoreception. PMID:27005398

    The usefulness and advantages of diagnostic ultrasound (sonar) scanning as an aid in the investigation of soft-tissue masses, are illustrated in a number of patients with such masses in the left upper quadrant of the abdomen. These illustrative cases show that sonar scanning can reveal the size, shape, anatomical relations, and consistency of intraperitoneal and retroperitoneal masses. Sonar scanning is particularly valuable in differentiating cystic from solid masses. Furthermore, clinically unsuspected masses can be detected. Sonar scanning is harmless, relatively quick, non-invasive and causes no pain or discomfort. These factors are of particular importance in postoperative and acutely ill patients.

    OBJECTIVE: To present a practical overview of the methods and techniques of auscultation of the chest and abdomen for use during the physical examination of athletes. Our intent is to provide information on this clinical technique to assist athletic trainers in recognizing and referring athletes presenting with potentially serious internal organ conditions. BACKGROUND: Use of the stethoscope is a clinical skill increasingly necessary for athletic trainers. Given the expanding breadth of both the assessment techniques used by athletic trainers and the populations they care for and the fact that clinical instruction guidelines have changed in the newly adopted National Athletic Trainers' Association Educational Competencies, our goal is to provide a framework upon which future instruction can be based. DESCRIPTION: This review covers the use of a stethoscope for auscultation of the chest and abdomen. Auscultation of the heart is covered first, followed by techniques for auscultating the breath sounds. Lastly, auscultation of the abdomen describes techniques for listening for bowel sounds and arterial bruits. CLINICAL ADVANTAGES: During the assessment of injuries to and illnesses of athletes, knowledge of auscultatory techniques is valuable and of increasing importance to athletic trainers. Athletic trainers who do not know how to perform auscultation may fail to recognize, and therefore fail to refer for further evaluation, athletes with potentially serious pathologic conditions.

Jejunal biopsies performed before and after cows' milk provocation were subjected to histological examination and to mucosal disaccharidase enzyme (lactase, sucrase, and maltase) analyses. After milk challenge, changes in mucosal histology were observed in 18 infants, in 17 of them the levels of all 3 mucosal disaccharidases were much reduced. 10 of these infants developed diarrhoea and, in 6, the stools were positive for reducing sugar. It is concluded that CMP has a deleterious effect on the jejunal mucosa of young infants recovering from infective enteritis, so that in the management of young infants with sugar intolerance secondary to infective enteritis, CMP and lactose should be excluded from the diet.

    Hypoxic hepatitis (HH) is a severe complication of postoperative low output syndrome, associated with high mortality rates despite appropriate drug therapy. Recently several extracorporeal supportive techniques have become available. We describe the case of a 70-year-old woman who developed HH secondary to cardiogenic shock after cardiac surgery. CPFA proved to be a valid tool for concomitant hemodynamic support and organ replacement therapy.

    Children with cerebral palsy and other neurologic diseases often present with sialorrhea. Intraglandular botulinum neurotoxin is being increasingly reported to be clinically effective for the treatment of sialorrhea. This treatment is becoming more popular in recent years because of being less invasive than surgical procedures. In addition, fewer adverse effects have been documented compared with oral or topical anticholinergic medication. We report the first case in a child with cerebral palsy who developed serious acute sialadenitis with submandibular sialolithiasis after intraglandular botulinum neurotoxin injection for sialorrhea.

    Aspergillus species have angioinvasive properties and can involve extrapulmonary organs by hematogenous spread from the lungs. However, renal involvement by Aspergillus is uncommon and is usually associated with the formation of abscesses. We report an unusual case of invasive renal aspergillosis presenting with extensive renal infarction in a 5-year-old girl with acute lymphoblastic leukemia. This case emphasizes the fact that renal aspergillosis initially presents with only renal infarction, and metastatic-embolism by invasive aspergillosis should be considered in differential diagnosis for any focal lesion of kidney in a patient with leukemia.

    Histiocytic sarcoma (HS) is a rare disease with poor prognosis which may develop subsequent to acute lymphoblastic leukemia (ALL). Here we report two children treated within the AIEOP-BFM ALL 2009 trial: one patient succumbed to fulminant hemophagocytic lymphohistiocytosis triggered by HS during ALL maintenance therapy, the other patient had a smoldering course of HS for over 2 years, and subsequently died after allogeneic stem cell transplantation. In both cases, HS and ALL were clonally related and apparent return of minimal residual disease (MRD) was detected by qPCR in bone marrow. Thus, HS should be considered in ALL when MRD appears to persist or reappear.

    Objective The purpose of this study was to assess satisfaction with specific aspects of care for acute neck pain and explore the relationship between satisfaction with care, neck pain and global satisfaction. Methods This study was a secondary analysis of patient satisfaction from a randomized trial of spinal manipulation therapy (SMT) delivered by doctors of chiropractic, home exercise and advice (HEA) delivered by exercise therapists, and medication (MED) prescribed by a medical physician for acute/subacute neck pain. Differences in satisfaction with specific aspects of care were analyzed using a linear mixed model. The relationship between specific aspects of care and 1) change in neck pain (primary outcome of the randomized trial) and 2) global satisfaction were assessed using Pearson’s correlation and multiple linear regression. Results Individuals receiving SMT or HEA were more satisfied with the information and general care received than MED group participants. SMT and HEA groups reported similar satisfaction with information provided during treatment; however, the SMT group was more satisfied with general care. Satisfaction with general care (r=−0.75 to −0.77, R2= 0.55 to 0.56) had a stronger relationship with global satisfaction compared to satisfaction with information provided (r=−0.65 to 0.67, R2=0.39 to 0.46). The relationship between satisfaction with care and neck pain was weak (r=0.17 to 0.38, R2=0.08 to 0.21). Conclusions Individuals with acute/subacute neck pain were more satisfied with specific aspects of care from SMT delivered by doctors of chiropractic or HEA interventions compared to MED prescribed by a medical physician.

    Introduction Recent research suggests that priapism in Sickle Cell Disease (SCD) is due to dysregulation of penile erection homeostasis including alteration of nitric oxide synthase (NOS) and phosphodiesterase 5 (PDE5) activities by excessive levels of reactive oxygen species (ROS) released during hemolysis. It is unknown if sub-acute exposure to hemolysis is sufficient or if chronic reconditioning of erectile tissues is required for perturbation of homeostatic pathways and whether PDE5 inhibitor (PDE5I) treatment can restore erectile homeostasis in the sub-acute setting. Aims To investigate the effects of sub-acute hemolysis (3 month exposure) on priapism and NO pathway regulation. Methods Mice underwent bone marrow transplantation with either SCD (BM-SS) or wild type (WT) bone marrow. BM-SS mice were treated with sildenafil 100mg/kg/day. We measured intracavernous pressure (ICP) measurements with or without cavernosal nerve stimulation (CNS) following bone marrow transplantation to assess for priapism. Main Outcome Measures ICP and frequency of erections were assessed. Penile tissues were analyzed for NOS, PKG, PDE5, and ROS activities. Results BM-SS mice demonstrated a priapism phenotype. PDE5I treatment reduced the frequency of erections in BM-SS mice (1.7 ± 1.1 vs. 5.5 ± 2.8 erections/hour, p<0.05). Penile tissues from BM-SS mice demonstrated decreased NOS, PKG, PDE5 and elevated ROS activities compared to that of control mice. PDE5I treatment increased NOS (11.6 ± 1.3% vs. 7.8 ± 2.3%, p<0.05) and PDE5 (76.3 ± 9.8% vs. 52.3 ± 11.1%, p<0.05) activities and decreased ROS activity (137.8 ± 12.1% vs. 199.1 ± 11.3%, p<0.05) compared to non-PDE5I treated BM-SS mice. PKG activity was increased beyond control levels with PDE5I treatment (158.4 ± 10.3%, p<0.05). Conclusion Short-term hemolysis is sufficient to establish a priapism phenotype and results in loss of erectile function. PDE5I treatment ameliorates priapism, in part, due to restored NO balance with

    We tested the hypothesis that proliferative activity of hematopoietic stem cells has impact on survival in newly diagnosed patients with myelodysplastic syndrome (MDS) and secondary acute myeloid leukemia (AML). RNA expression profiles of CD34(+) cells were analyzed in 125 MDS patients and compared to healthy controls. Prognostic impact on overall survival (OS) of mRNA proliferation signatures established for solid tumor cells was analyzed retrospectively. For validation on the protein level, immunofluorescence and immunohistochemistry analyses in bone marrow (BM) biopsies were performed, and an independent cohort of 223 MDS and secondary AML patients was investigated. Lower proliferative activity correlated with the expression of cyclin-dependent kinase inhibitor 1C (CDKN1C) and with shorter OS (p < 0.001). In multivariable analysis, higher CDKN1C expression was associated with worse OS (p = 0.02). On the BM level, a total of 84 (38%) patients showed CDKN1C protein expression before start of treatment. Patient, disease and treatment characteristics did not differ between CDKN1C-positive and -negative patients. Positive CDKN1C BM status was associated with shorter OS in multivariable analysis (HR 1.54, p = 0.04). There was an interaction between CDKN1C BM status and subsequent treatment with negative impact on OS being most pronounced in patients receiving conventional cytotoxic chemotherapy (n = 83, 2-year OS 30% versus 58%, p = 0.002). In conclusion, low-proliferative phenotype and CDKN1C expression were associated with shorter OS. CDKN1C protein expression in the BM of newly diagnosed, treatment-naïve MDS and secondary AML patients was identified as a prognostic factor for poor survival in patients treated with antiproliferative chemotherapy.

    ABSTRACT Statin and antiplatelet drugs are widely used for prevention of ischaemic stroke and other cardiovascular diseases in high-risk patients. We report a rare case of a 49-year old man with a history of myocardial infarction and hyperlipidaemia who suffered an acute occlusion of his innominate artery (IA) accompanied by subclavian steal syndrome and cerebral infarction, on day seven after abrupt cessation of aspirin and statin, as confirmed by magnetic resonance and computed tomographic angiography of head and neck, and colour-coded Duplex ultrasonography (CCDU). Aspirin and atorvastatin were immediately re-started on admission. Spontaneous recanalization of IA was shown on repeat CCDU and digital subtraction angiography on day 10 after stroke onset. This case serves as a reminder that abrupt discontinuation of both aspirin and statin in patients with previous history of cardiovascular disease may increase the risk of ischaemic stroke.

    Experimental and clinical studies analyzing the impact of AVF on cardiovascular and renal parameters, as well as outcomes, in kidney transplant recipients are lacking. On the other hand, it is not known whether AVF ligation after transplantation modifies hemodynamic parameters and kidney function. We report a case of a renal transplant recipient who developed an acute congestive heart failure accompanied by renal failure, which were triggered by femorofemoral AVF angioplasty. Prompt AVF ligation rapidly reversed clinical symptoms and normalized cardiac and renal functions. This paper illustrates the potential deleterious consequences of high-output AVF after kidney transplantation and raises considerations regarding the impact of the fistula on cardiac status and kidney function after kidney transplantation and, consequently, the management AVF after transplantation.

    The case of a 78-year-old African American woman who presented at the Mount Sinai Medical Center (Chicago, USA) with excruciating backache is presented. Computed tomography of the chest at the time of admission showed dissection of the aortic arch, descending aorta and dissection of an aberrant right subclavian artery. She was managed medically for Stanford type B acute aortic dissection. The patient was asymptomatic at presentation, but started complaining of new-onset dysphagia during her stay in the hospital. An esophagogram was performed and suggested posterior impingement of the esophagus, a classic sign of an aberrant right subclavian artery. Because the patient had multiple underlying comorbidities and the dysphagia was mild and intermittent, surgery was deferred. The patient was discharged home after complete stabilization and was scheduled for a follow-up appointment. PMID:18209773

    We report on a 42-year-old male who presented with priapism, severe scrotal swelling, and left lower extremity pain and swelling. Initial management of priapism failed, and he was noted to have both cavernosal and glandular venous obstruction. Computed tomography (CT) was performed and identified extensive acute thrombosis involving the distal inferior vena cava and the left iliac veins. Pharmacomechanical thrombolysis (PMT) was started over the course of two days. At completion of thrombolysis, the culprit lesion in the left common iliac vein was treated with angioplasty and stenting. His postoperative course was uneventful, and his priapism as well as the scrotal and leg swelling improved. He was discharged home on full anticoagulation. To our knowledge, this is the first available description of this rare presentation along with a literature review of the underlying vascular etiology for priapism.

    Injury potential, which refers to a direct current voltage between intact and injured nerve ends, is mainly caused by injury-induced Ca2+ influx. Our previous studies revealed that injury potential increased with the onset and severity of spinal cord injury (SCI), and an application of applied electric field stimulation (EFS) with the cathode distal to the lesion could delay and attenuate injury potential formation. As Ca2+ influx is also considered as a major trigger for secondary injury after SCI, we hypothesize that EFS would protect an injured spinal cord from secondary injury and consequently improve functional and pathological outcomes. In this study, rats were divided into three groups: (1) sham group, laminectomy only; (2) control group, subjected to SCI only; and (3) EFS group, received EFS immediately post-injury with the injury potential modulated to 0±0.5 mV by EFS. Functional recovery of the hind limbs was assessed using the Basso, Beattie, and Bresnahan (BBB) locomotor scale. Results revealed that EFS-treated rats exhibited significantly better locomotor function recovery. Luxol fast blue staining was performed to assess the spared myelin area. Immunofluorescence was used to observe the number of myelinated nerve fibers. Ultrastructural analysis was performed to evaluate the size of myelinated nerve fibers. Findings showed that the EFS group rats exhibited significantly less myelin loss and had larger and more myelinated nerve fibers than the control group rats in dorsal corticospinal tract (dCST) 8 weeks after SCI. Furthermore, we found that EFS inhibited the activation of calpain and caspase-3, as well as the expression of Bax, as detected by Western blot analysis. Moreover, EFS decreased cellular apoptosis, as measured by TUNEL, within 4 weeks post-injury. Results suggest that early EFS could significantly reduce spinal cord degeneration and improve functional and historical recovery. Furthermore, these neuroprotective effects may be related to

    Management of the burst abdomen is complex due to the co-morbidities associated with it. When coupled with intraabdominal sepsis and pregnancy, it becomes even more difficult due to the ethical issues that have to be considered when managing both mother and child. Due to the paucity of literature on this subject, a management algorithm has been proposed which aims at tackling this delicate issue. However, the major consideration in the management of these cases is that decisions are to be made based on optimization of the condition of the mother. PMID:27635100

This article presents the case of a 41-year-old office worker, whose job involved client services. While attending a very aggressive customer she developed solid stress that resulted in symptoms of the central nervous system (headache, speech disturbances). During her hospitalisation at the neurological unit ischemic stroke with transient mixed type aphasia was diagnosed. Magnetic resonance imaging (MRI) scan of the head revealed subacute ischemia. After an analysis of the accident circumstances, the employer's post accidental team decided that ischemic stroke had been an accident at work, because it was a sudden incident due to an external cause inducing work-related traumatic stroke. As a primary cause tough stress and emotional strain due to the situation developed while attending the customer were acknowledged. During control medical check up after 5 months the patient was found to be fit for work, so she could return to work. However, it should be noted that such a check up examination of subjects returning to work after stroke must be holistic, including the evaluation of job predispositions and health education aimed at secondary prevention of heart and vascular diseases with special reference to their risk factors.

    Immediate closure of abdominal incisions after exploration and treatment of gunshot wounds is not always feasible or advisable. Significant bowel edema after massive fluid resuscitation might preclude primary closure, whereas any attempt to close under tension might result in complications ranging from wound dehiscence, infection, and necrosis to the abdominal compartment syndrome with abdominal, cardiopulmonary, and renal complications. For these difficult cases, the open technique has been recommended. The abdomen is left open and is closed when the patient's condition permits. When immediate wound approximation is not possible, temporary coverage can be achieved with a mesh, patch, or a split-thickness skin graft and the definitive reconstruction is deferred for a more optimal time. The purpose of this retrospective study is to report the authors' experience with staged abdominal wall reconstruction after gunshot wounds. From 1989 to 1998, 1933 patients underwent exploratory laparotomy for penetrating wounds to the abdomen. Twenty-nine patients in grave condition and with multiple medical problems were comanaged by the Trauma and Plastic Surgery Services at Cook County Hospital with the following protocol: The abdomen was initially left open and exposed viscera were covered with a variety of methods, including a Gore-Tex patch (W. L. Gore and Associates, Inc., Flagstaff, Ariz.). A split-thickness graft was subsequently placed on the granulation tissue over viscera at an average of 14 days after the last laparotomy. These planned ventral hernias were definitively treated at an average of 7 months after the skin grafting procedure, primarily using the components separation technique. In 24 patients, the fascia was closed primarily without tension, while five patients required the use of synthetic mesh to restore fascial continuity. Nine patients underwent closure of a colostomy or repair of fistulas simultaneously with abdominal wall reconstruction. One patient

    The authors present the complications due to subcutaneous injections on two patients suffering from morbid obesity with an abdomen pendulum. In the first case, injections of heparin of low molecular weight at curative dose, for treatment of a pulmonary embolism, have been complicated with a giant abdominal wall haematoma, the biggest ever reported. The initial treatment was insufficient so we had to practice a dermolipectomy to take off the haematoma of four litters. In the second case, insulin injections were complicated with cellulitis of the abdominal wall and a surgical treatment has been practiced in emergency. The first case reminds us the importance to change the sites of injections and to accommodate the dose, surgical treatment staying as simple as possible. The second case allows us to report a rare complication, not often published but known with obese patients. These two cases illustrate the importance of therapeutic education of the patient and the fact that a simple injection can be life threatening.

    Different possibilities of coordination between circulation, respiration and abdominal movements were found in pupae of Pieris brassicae, Tenebrio molitor, Galleria mellonella and Leptinotarsa decemlineata. Coordination principles depend on metabolic rate: the need to support circulation with abdominal movements appears only at higher metabolic rates. Integration between different abdominal movements and circulation depends on species, on physiological state and, supposedly, on internal morphology. At low metabolic rates, there is no need for a very intensive hemolymph flow, and the dorsal vessel is capable of initiating and/or maintaining necessary hemolymph flow. Starting from a certain metabolic level, it is possible that the abdomen is used to accelerate hemolymph flow in the case of a large amount of hemolymph. When the necessary flow speed has been reached, relatively weak pulsation of the dorsal vessel with accessory pulsatile organs and diaphragms can easily maintain the necessary flow intensity. Heart activity may sometimes be initiated by abdominal movements via cardiac reflex or mechanical excitation. Sometimes, when heart function is weakened by histolysis, the abdomen may temporarily take over the main circulatory function or occasionally contribute to acceleration of low-speed hemolymph flow. In this case the functions are simultaneous and may be triggered by some mediator(s). In active adult insects the whole body is moving, and hence hemolymph circulates and the tracheal system is effectively ventilated by a whole body ensemble consisting of the dorsal vessel, moving organs, body appendages and accessory pulsatile organs. The mechanism of autocirculation (analogous to autoventilation in gas exchange) is a probable mechanism in circulation in adult insects. PMID:12443919

    INTRODUCTION Traumatic abdominal wall hernia (TAWH) and traumatic abdominal aortic injury (TAAI) are two uncommon complications secondary to blunt trauma. In both TAWH and TAAI, reported cases are often associated with poly-trauma. TAWH may be initially missed if more pressing issues are identified during the patient's primary survey. TAAI may be an incidental finding on imaging or, if severe, a cause of an acute abdomen and hemodynamic abnormality. PRESENTATION OF CASE A 54-year-old white male suffered a TAWH and TAAI (pseudoaneurysm) due to severe blunt trauma. TAWH was apparent on physical exam and the TAAI was suspected on computed tomography (CT). The patient's TAWH was managed with a series of abdominal explorations and the TAAI was repaired with endovascular stenting. DISCUSSION TAWH and TAAI are commonly due to severe blunt trauma from motor vehicle collisions. Diagnosis is made through physical exam, imaging studies, or surgical exploration. A variety of surgical techniques achieve technical success. CONCLUSION The patient with blunt trauma to the abdomen is at risk for TAWH and TAAI, which are often associated with other injuries. Investigations should include thorough clinical exam through secondary survey and radiologic imaging in the hemodynamically normal patient. PMID:25437685

    Magnetic resonance (MR) imaging provides multiplanar large field-of-view images of the body with excellent soft-tissue contrast and without ionizing radiation. As a result, MR imaging is increasingly being used to image the maternal abdomen and pelvis during and immediately after pregnancy. Results of rapid T1- and T2-weighted imaging are often diagnostic, and blood vessels, ductal structures, and the urinary tract can frequently be visualized without intravenous administration of contrast material. Until more conclusive safety data become available, MR imaging should be reserved for cases in which results of ultrasonography are inconclusive and patient care depends on further imaging. In the setting of acute abdomen during pregnancy, MR imaging allows identification of areas of inflammation, abscess formation, hemorrhage, and bowel obstruction. MR imaging also helps determine the organ of origin, extent, and composition of maternal neoplasms and is useful in evaluation of müllerian duct anomalies and abnormalities of placental formation, position, and implantation. Many postpartum complications such as retained products of conception and uterine dehiscence may be diagnosed with MR imaging when results of other modalities are indeterminate.

    A resource allocation trade-off is expected when resources from a common pool are allocated to two or more traits. In holometabolous insects, resource allocation to different functions during metamorphosis relies completely on larval-derived resources. At adult eclosion, resource allocation to the abdomen at the expense of other body parts can be seen as a rough estimate of resource allocation to reproduction. Theory suggests geographic variation in resource allocation to the abdomen, but there are currently no empirical data on it. We measured resource allocation to the abdomen at adult eclosion in four geometrid moths along a latitudinal gradient. Resource (total dry material, carbon, nitrogen) allocation to the abdomen showed positive allometry with body size. We found geographic variation in resource allocation to the abdomen in each species, and this variation was independent of allometry in three species. Geographic variation in resource allocation to the abdomen was complex. Resource allocation to the abdomen was relatively high in partially bivoltine populations in two species, which fits theoretical predictions, but the overall support for theory is weak. This study indicates that the geographic variation in resource allocation to the abdomen is not an allometric consequence of geographic variation in resource acquisition (i.e., body size). Thus, there is a component of resource allocation that can evolve independently of resource acquisition. Our results also suggest that there may be intraspecific variation in the degree of capital versus income breeding.

    The subserous space is a large, anatomically continuous potential space that interconnects the chest, abdomen, and pelvis. The subserous space is formed from areolar and adipose tissue, and contains branches of the vascular, lymphatic, and nervous systems. As such, it provides one large continuous space in which many disease processes can spread between the chest, abdomen, and the pelvis.

    A resource allocation trade-off is expected when resources from a common pool are allocated to two or more traits. In holometabolous insects, resource allocation to different functions during metamorphosis relies completely on larval-derived resources. At adult eclosion, resource allocation to the abdomen at the expense of other body parts can be seen as a rough estimate of resource allocation to reproduction. Theory suggests geographic variation in resource allocation to the abdomen, but there are currently no empirical data on it. We measured resource allocation to the abdomen at adult eclosion in four geometrid moths along a latitudinal gradient. Resource (total dry material, carbon, nitrogen) allocation to the abdomen showed positive allometry with body size. We found geographic variation in resource allocation to the abdomen in each species, and this variation was independent of allometry in three species. Geographic variation in resource allocation to the abdomen was complex. Resource allocation to the abdomen was relatively high in partially bivoltine populations in two species, which fits theoretical predictions, but the overall support for theory is weak. This study indicates that the geographic variation in resource allocation to the abdomen is not an allometric consequence of geographic variation in resource acquisition (i.e., body size). Thus, there is a component of resource allocation that can evolve independently of resource acquisition. Our results also suggest that there may be intraspecific variation in the degree of capital versus income breeding.

    Background and Objectives The differential benefit of statin according to the state of dyslipidemia has been sparsely investigated. We sought to address the efficacy of statin in secondary prevention of myocardial infarction (MI) according to the level of triglyceride and high density lipoprotein cholesterol (HDL-C) on admission. Subjects and Methods Acute MI patients (24653) were enrolled and the total patients were divided according to level of triglyceride and HDL-C on admission: group A (HDL-C≥40 mg/dL and triglyceride<150 mg/dL; n=11819), group B (HDL-C≥40 mg/dL and triglyceride≥150 mg/dL; n=3329), group C (HDL-C<40 mg/dL and triglyceride<150 mg/dL; n=6062), and group D (HDL-C<40 mg/dL & triglyceride≥150 mg/dL; n=3443). We evaluated the differential efficacy of statin according to the presence or absence of component of dyslipidemia. The primary end points were major adverse cardiac events (MACE) for 2 years. Results Statin therapy significantly reduced the risk of MACE in group A (hazard ratio=0.676; 95% confidence interval: 0.582-0.785; p<0.001). However, the efficacy of statin was not prominent in groups B, C, or D. In a propensity-matched population, the result was similar. In particular, the benefit of statin in group A was different compared with group D (interaction p=0.042) Conclusion The benefit of statin in patients with MI was different according to the presence or absence of dyslipidemia. In particular, because of the insufficient benefit of statin in patients with MI and dyslipidemia, a different lipid-lowering strategy is necessary in these patients. PMID:27275169

    Objective Comprehensive profiling of gene expression in peripheral blood leucocytes (PBLs) in patients with acute coronary syndrome (ACS) as a prognosticator is needed. We explored the specific profile of gene expression in PBLs in ACS for long-term risk stratification. Methods 30 patients with ACS who underwent primary percutaneous coronary intervention (PCI) and 15 age-matched adults who participated in medical check-ups were enrolled from three centres. Peripheral blood samples were collected to extract RNA for microarray analyses. Results During the 5-year follow-up, 36% of this cohort developed the expected non-fatal coronary events (NFEs) of target lesion revascularisation (TLR) and PCI for a de novo lesion. Class comparison analysis (p<0.005) demonstrated that 83 genes among 7785 prefiltered genes (41 upregulated vs 42 downregulated genes) were extracted to classify the patients according to the occurrence of NFE. Pathway analysis based on gene ontology revealed that the NFEs were associated with altered gene expression regarding the T-cell receptor signalling pathway in ACS. Univariate t test showed that the expression level of death-associated protein kinase1 (DAPK1), known to regulate inflammation, was the most significantly negatively regulated gene in the event group (0.61-fold, p<0.0005). Kaplan-Meier curve analysis and multivariate analysis adjusted for baseline characteristics or clinical biomarkers demonstrated that lower DAPK1 expression in PBL emerged as an independent risk factor for the NFEs (HR: 8.73; CI 1.05 to 72.8, p=0.045). Conclusions Altered gene expression in T-cell receptor signalling in PBL in ACS could be a prognosticator for secondary coronary events. Trial registration number UMIN000001932; Results.

    INTRODUCTION Acute appendicitis commonly presents as an acute abdomen. Cases of acute appendicitis caused by blunt abdominal trauma are rare. We present a systematic review of appendicitis following blunt abdominal trauma. The aim of this review was to collate and report the clinical presentations and experience of such cases. SUBJECTS AND METHODS A literature review was performed using PubMed, Embase and Medline and the keywords ‘appendicitis’, ‘abdominal’ and ‘trauma’. RESULTS The initial search returned 381 papers, of which 17 articles were included. We found 28 cases of acute appendicitis secondary to blunt abdominal trauma reported in the literature between 1991 and 2009. Mechanisms of injury included road-traffic accidents, falls, assaults and accidents. Presenting symptoms invariably included abdominal pain, but also nausea, vomiting and anorexia. Only 12 patients had computed tomography scans and 10 patients had ultrasonography. All reported treatment was surgical and positive for appendicitis. CONCLUSIONS Although rare, the diagnosis of acute appendicitis must be considered following direct abdominal trauma especially if the patient complains of abdominal right lower quadrant pain, nausea and anorexia. Haemodynamically stable patients who present shortly after blunt abdominal trauma with right lower quadrant pain and tenderness should undergo urgent imaging with a plan to proceed to appendicectomy if the imaging suggested an inflammatory process within the right iliac fossa.

    Abdominal compartment syndrome (ACS) is a known complication of laparotomy; however, the literature is lacking in regards to treatment of this entity in pregnant patients. We present a case of acute perforated appendicitis in a second trimester primagravida, complicated by gangrenous necrosis of the contiguous bowel with subsequent development of ACS and intra-abdominal sepsis. This was treated with a novel approach, using non-commercial negative pressure wound therapy and open abdomen technique. Gestational integrity was preserved and the patient went on to experience a normal spontaneous vaginal delivery. At 5 years post-delivery the patient has had no surgical complications and her baby has met all developmental milestones. PMID:27302498

    Radiological measurements are one of the key variables in widely adopted guidelines (WHO, RECIST) that standardize and objectivize response assessment in oncology care. Measurements are typically described in free-text, narrative radiology reports. We present a natural language processing pipeline that extracts measurements from radiology reports and pairs them with extracted measurements from prior reports of the same clinical finding, e.g., lymph node or mass. A ground truth was created by manually pairing measurements in the abdomen CT reports of 50 patients. A Random Forest classifier trained on 15 features achieved superior results in an end-to-end evaluation of the pipeline on the extraction and pairing task: precision 0.910, recall 0.878, F-measure 0.894, AUC 0.988. Representing the narrative content in terms of UMLS concepts did not improve results. Applications of the proposed technology include data mining, advanced search and workflow support for healthcare professionals managing radiological measurements. PMID:24551406

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

    Active shape models (ASMs) have been widely used for extracting human anatomies in medical images given their capability for shape regularization of topology preservation. However, sensitivity to model initialization and local correspondence search often undermines their performances, especially around highly variable contexts in computed-tomography (CT) and magnetic resonance (MR) images. In this study, we propose an augmented ASM (AASM) by integrating the multiatlas label fusion (MALF) and level set (LS) techniques into the traditional ASM framework. Using AASM, landmark updates are optimized globally via a region-based LS evolution applied on the probability map generated from MALF. This augmentation effectively extends the searching range of correspondent landmarks while reducing sensitivity to the image contexts and improves the segmentation robustness. We propose the AASM framework as a two-dimensional segmentation technique targeting structures with one axis of regularity. We apply AASM approach to abdomen CT and spinal cord (SC) MR segmentation challenges. On 20 CT scans, the AASM segmentation of the whole abdominal wall enables the subcutaneous/visceral fat measurement, with high correlation to the measurement derived from manual segmentation. On 28 3T MR scans, AASM yields better performances than other state-of-the-art approaches in segmenting white/gray matter in SC. PMID:27610400

    The modern ultrasound dopplerography give us the big possibilities in investigation of gemodynamical changes in all stages of abdomen pathology. Many of researches devoted to using of noninvasive methods in practical medicine. Now ultrasound Dopplerography is one of the basic one. We investigated 250 patients from 30 to 77 ages, including 149 men and 101 women. The basic diagnosis of all patients was the Ischaemic Pancreatitis. The Second diagnoses of pathology were the Ischaemic Disease of Heart, Gypertension, Atherosclerosis, Diabet, Vascular Disease of Extremities. We researched the abdominal aorta and her branches: Arteria Mesenterica Superior (AMS), truncus coeliacus (TC), arteria hepatica communis (AHC), arteria lienalis (AL). For investigation we use the following equipment: ACUSON 128 XP/10c, BIOMEDIC, GENERAL ELECTRIC (USA, Japan). We analyzed the following componetns of gemodynamical changes of abdominal vessels: index of pulsation, index of resistance, ratio of systol-dystol, speed of blood circulation. Statistical program included the following one: 'basic statistic's,' 'analytic program.' In conclusion we determined that the all gemodynamical components of abdominal vessels had considerable changes in abdominal ischaemia than in normal situation. Using the computer's program for definition degree of gemodynamical changes, we can recommend the individual plan of diagnostical and treatment program.

    Dual-energy computed tomographic (DECT) technology offers enhanced capabilities that may benefit oncologic imaging in the abdomen. By using two different energies, dual-energy CT allows material decomposition on the basis of energy-dependent attenuation profiles of specific materials. Although image acquisition with dual-energy CT is similar to that with single-energy CT, comprehensive postprocessing is able to generate not only images that are similar to single-energy CT (SECT) images, but a variety of other images, such as virtual unenhanced (VUE), virtual monochromatic (VMC), and material-specific iodine images. An increase in the conspicuity of iodine on low-energy VMC images and material-specific iodine images may aid detection and characterization of tumors. Use of VMC images of a desired energy level (40-140 keV) improves lesion-to-background contrast and the quality of vascular imaging for preoperative planning. Material-specific iodine images enable differentiation of hypoattenuating tumors from hypo- or hyperattenuating cysts and facilitate detection of isoattenuating tumors, such as pancreatic masses and peritoneal disease, thereby defining tumor targets for imaging-guided therapy. Moreover, quantitative iodine mapping may serve as a surrogate biomarker for monitoring effects of the treatment. Dual-energy CT is an innovative imaging technique that enhances the capabilities of CT in evaluating oncology patients. PMID:24819783

    Honeybees (Apis mellifera) curl their abdomens for daily rhythmic activities. Prior to determining this fact, people have concluded that honeybees could curl their abdomen casually. However, an intriguing but less studied feature is the possible unidirectional abdominal deformation in free-flying honeybees. A high-speed video camera was used to capture the curling and to analyze the changes in the arc length of the honeybee abdomen not only in free-flying mode but also in the fixed sample. Frozen sections and environment scanning electron microscope were used to investigate the microstructure and motion principle of honeybee abdomen and to explore the physical structure restricting its curling. An adaptive segmented structure, especially the folded intersegmental membrane (FIM), plays a dominant role in the flexion and extension of the abdomen. The structural features of FIM were utilized to mimic and exhibit movement restriction on honeybee abdomen. Combining experimental analysis and theoretical demonstration, a unidirectional bending mechanism of honeybee abdomen was revealed. Through this finding, a new perspective for aerospace vehicle design can be imitated. PMID:26223946

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

    A contained open abdomen is commonly used during damage control laparotomy and consists of the temporary coverage of the abdomen for protection of the viscera and reduction of intra-abdominal pressure. Definitive closure of a contained open abdomen is technically difficult due to the inability to obtain primary fascial suture. The insertion of a prosthetic mesh can be complicated with enterocutaneous fistula, and other definitive closure techniques need several surgical procedures. We describe a low cost technique that allows definitive closure of large abdominal wall defects avoiding the risk of intestinal fistula.

    Three cases of acute intermittent porphyria are reported. While in first case severe pain in abdomen with intermittent exacerbation was the only presentation, the second patient presented as accelerated hypertension and acute abdominal crises in whom the clinical course was characterized by development of deep coma due to inappropriate secretion of antidiuretic hormone before she made complete recovery. The third patient, initially manifested as acute encephalitic syndrome. After initial improvement, she developed features of acute intermittent porphyria i.e. acute abdomen, neuropsychiatric symptoms, and rapidly progressing acute motor neuropathy leading to respiratory and bulbar paralysis. In addition, she developed severe and fluctuating dysautonomia leading to cardiac arrest and fatal termination. The importance of early diagnosis, recognition of autonomic disturbances, prompt treatment and counseling for avoidance of precipitating factors is stressed.

    Torsion of the fatty appendage of the falciform ligament is an extremely rare condition that leads to severe abdominal pain and raised inflammatory markers. It can be recognised on ultrasound or CT scan. The pathophysiology is the same as that involved in the more common torsion and/or infarction of the greater omentum or epiploic appendages. The condition is best managed conservatively with anti-inflammatory analgesia, and the early recognition of this type of torsion may prevent unnecessary operative intervention to look for a source of abdominal pain. There have been five reported adult cases of a torted fatty appendage of the falciform ligament identified on ultrasound and CT scan, but no paediatric cases. We report a case of torsion of the fatty appendage of the falciform ligament in a ten-year-old boy and describe its imaging characteristics on CT scan. PMID:26664796

    During the 10-year period 1974-1983, 68 patients with intraperitoneal haemorrhage as a result of the rupture of a corpus luteum were managed at the University Hospital, Kuala Lumpur, Malaysia. Most of the patients were aged between 18 and 35 years. In 63% of the patients the rupture occurred between the 14th and the 35th day of the menstrual cycle, and 10 patients had intraperitoneal bleeding severe enough (450-1500 mL) to require blood transfusion. The condition is often confused with other surgical emergencies such as appendicitis and ectopic pregnancy. An increased awareness of the problem in women of reproductive age and the use of laparoscopy, when indicated, will allow a more conservative approach to be adopted for those patients with minimal bleeding. The performance of an appendicectomy in the presence of blood in the peritoneal cavity did not appear to increase morbidity in those patients with a preoperative diagnosis of "appendicitis".

    The folded intersegmental membrane is a structure that interconnects two adjacent abdominal segments; this structure is distributed in the segments of the honey bee abdomen. The morphology of the folded intersegmental membrane has already been documented. However, the ultrastructure of the intersegmental membrane and its assistive role in the telescopic movements of the honey bee abdomen are poorly understood. To explore the morphology and ultrastructure of the folded intersegmental membrane in the honey bee abdomen, frozen sections were analyzed under a scanning electron microscope. The intersegmental membrane between two adjacent terga has a Z-S configuration that greatly influences the daily physical activities of the honey bee abdomen. The dorsal intersegmental membrane is 2 times thicker than the ventral one, leading to asymmetric abdominal motion. Honey bee abdominal movements were recorded using a high-speed camera and through phase-contrast computed tomography. These movements conformed to the structural features of the folded intersegmental membrane. PMID:27456912

    In this paper, we derive longitudinal nonlinear equations of motion of a hovering insect with deformable abdomen to investigate the effect of the abdominal motion to the longitudinal dynamics. The blade-element theory, which is based on experimentally obtained aerodynamic coefficients, is used for the periodic force and moment excitation to the system. Here, we focus on the role of the deformable abdomen to investigate whether or not the flexible body is a decisive factor to the longitudinal flight dynamic stability. Three cases: 1) rigid connection between the thorax and abdomen, 2) flexible connection, and 3) active connection with a feedback control, are compared to check the role of the abdomen deformation on the longitudinal flight dynamic stability, by examining eigenvalues of the linearized system model of each case. The results show that an active control of the abdominal angle can stabilize the longitudinal flight dynamics of the insect modeled in this study.

    According to accident analysis, submarining is responsible for most of the frontal car crash AIS 3+ abdominal injuries sustained by restrained occupants. Submarining is characterized by an initial position of the lap belt on the iliac spine. During the crash, the pelvis slips under the lap belt which loads the abdomen. The order of magnitude of the abdominal deflection rate was reported by Uriot to be approximately 4 m/s. In addition, the use of active restraint devices such as pretensioners in recent cars lead to the need for the investigation of Out-Of-Position injuries. OOP is defined by an initial position of the lap belt on the abdomen instead of the pelvis resulting in a direct loading of the abdomen during pretensioning and the crash. In that case, the penetration speed of the belt into the abdomen was reported by Trosseille to be approximately 8 to 12 m/s. The aim of this study was to characterize the response of the human abdomen in submarining and OOP. A total of 8 PMHS abdomens were loaded using a lap belt. In order to investigate the injury mechanisms, the abdominal deflection rate and the compression were imposed such that they were not correlated. The specimens were seated upright in a fixed back configuration. The lap belt was placed at the level of the mid-umbilicus, between the iliac crest and the 12th rib. The belt was pulled horizontally along the sides of the specimens causing a symmetrical loading of the abdomen. In addition to the local parameters such as the belt and back forces or the belt displacements, the 3D external deformation of the abdomen was recorded. The forces measured between the back of the cadaver and the seat showed that a mass effect should be taken into account in the abdominal behaviour in addition to viscosity. The back force was greater than the belt force in low speed (submarining like) tests while it was lower for high-speed (OOP like) tests. A lumped parameter model was developed to confirm the experimental results and

    Ferromagnetic resonance temperature dependence is used to study the magnetic material in smashed head, thorax, and abdomen of Solenopsis substituta ants. These three body parts present the five lines previously observed in other social insects. The magnetic material content is slightly higher in heads with antennae than in abdomen with petiole. Isolated nanoparticle diameters were estimated as 12.5 ± 0.1 and 11.0 ± 0.2 nm in abdomen with petiole and head with antennae, respectively. The presence of linear chains of these particles or large ellipsoidal particles are suggested. A bulk-like magnetite particle was observed in the thorax. The Curie-Weiss, the structural-electronic and ordering transition temperatures were obtained in good agreement with those proposed for magnetite nanoparticles.

    A 52-year-old woman presented to the accident and emergency department 5 h after deliberately stabbing herself with two pens through her midline laparotomy scar. Her medical history included an emotionally unstable (borderline) personality disorder and she was currently an inpatient in a psychiatric hospital. She had multiple accident and emergency attendances with previous episodes of self-harm. Clinical examination revealed evidence of trauma to her midline laparotomy scar with congealed blood covering the puncture site. Her abdomen was soft and non-tender on palpation. A chest radiograph revealed no air beneath her diaphragm and her abdominal radiograph identified a radiopacity in her upper right abdomen and dilated loops of small bowel. CT of the abdomen and pelvis confirmed two pens, with the lower pen tip reaching the pancreas. A midline laparotomy was performed and both foreign bodies were extricated unremarkably. The patient's postoperative recovery was uneventful. The second case involves a 22-year-old woman, a psychiatric hospital resident, presenting to the accident and emergency department 5 h after deliberately inserting the metal nib and inner plastic ink containing tube of a pen through her umbilicus. Her medical history included an emotionally unstable (borderline) personality disorder and paranoid schizophrenia. She had multiple accident and emergency department attendances with previous episodes of self-harm. Clinical examination revealed a soft, non-tender abdomen. Her chest radiograph was unremarkable and her abdominal radiograph identified a radiopaque foreign body at the right upper quadrant of the abdomen. CT of the abdomen and pelvis confirmed a metallic foreign body in the small bowel mesentery. An exploratory laparotomy converted to a midline laparotomy was performed and the foreign body was extricated. The patient's postoperative recovery was uneventful. PMID:26245285

    In this report, we describe the case of an adult male who developed an acute compartment syndrome localized to the anterior compartment of the leg following an ankle sprain. Compartment syndrome in association with ankle sprain is unusual, and has been previously described in association with avulsion of the perforating peroneal artery. Because of the potential for severe morbidity, we feel that it is important to make foot and ankle surgeons aware of this unusual injury.

    Patient: Female, 33 Final Diagnosis: Acute cholecystitis after Familial Mediterranean Fever-related peritonitis Symptoms: Acute abdomen • fever Medication: Colchicine Clinical Procedure: Laparoscopic cholecystectomy and adhesiolysis in the second trimester of pregnancy Specialty: Surgery Objective: Rare co-existance of disease or pathology Background: Differential diagnosis of acute abdomen in pregnant patients is one of the greatest challenges for the clinician. Occurrence of Familial Mediterranean Fever (FMF) paroxysm of peritonitis and acute cholecystitis during pregnancy is a unique clinical entity that leads to serious diagnostic and therapeutic dilemmas. Case Report: We present the case of a 33-year-old Armenian patient at 16 weeks’ gestational age with a history of FMF, who was admitted twice within 1 month with acute abdomen. The first episode was attributed to FMF and successfully treated conservatively with colchicine. The second episode was diagnosed as acute cholecystitis and led to emergent laparoscopic cholecystectomy and lysis of peritoneal adhesions from previous FMF attacks. The patient presented an uneventful postoperative clinical course and had a normal delivery of a healthy infant at the 39th week of gestation. Conclusions: Pregnant patients with acute abdomen should be evaluated with open mind. To the best of our knowledge, this is the first published report of the coexistence of 2 different causes of acute abdomen during pregnancy. Meticulous history and thorough physical, laboratory, and radiologic examination are the keys to reach a correct diagnosis. Treatment of pregnant patients with acute abdomen should be individualized. Administration of colchicine should be continued during conception, pregnancy, and lactation in patients with FMF history. Laparoscopic intervention in pregnant patients with surgical abdomen such as acute cholecystitis is the optimal method of treatment. PMID:26907752

    Sebaceous carcinoma is a rare, aggressive cutaneous tumor most commonly involving the head and neck, especially the periorbital area. It has been associated with Muir–Torre syndrome, human papillomavirus infection, and radiotherapy. This case report describes an unusual clinical presentation of a large sebaceous carcinoma on the abdomen of an African-American male patient who was successfully treated with Mohs micrographic surgery. The case is reported due to the unusual location of the lesion on the abdomen and the rare occurrence of this tumor type in an African-American male. PMID:26904445

    Choroid plexus cysts are common and typically asymptomatic abnormal folds of the epithelial lining of the choroid plexus. Rarely, these cysts may gradually enlarge and cause outflow obstruction of cerebrospinal fluid. The authors present a case of a large choroid plexus cyst causing acute hydrocephalus in a previously healthy 2-year-old boy. The patient presented with markedly declining mental status, vomiting, and bradycardia over the course of several hours. Computed tomography scans demonstrated enlarged lateral and third ventricles with sulcal effacement, but no obvious mass lesions or hemorrhage. There was no antecedent illness or trauma. A right frontal external ventricular drain was placed in the patient, resulting in decompression of only the right lateral ventricle. Magnetic resonance (MR) imaging demonstrated a lobulated cyst arising from the choroid plexus of the left lateral ventricle and herniating through the foramen of Monro into the third ventricle, occluding both the foramen of Monro and the cerebral aqueduct. The patient underwent an endoscopic fenestration of the cyst, and histological results confirmed that it was a choroid plexus cyst. Postoperative MR imaging showed a marked reduction in the cyst size. The cyst was no longer in the third ventricle, the foramen of Monro and the aqueduct were patent, and the ventricles were decompressed. The patient was discharged home with no deficits. To the authors' knowledge, there are no previous reports of a choroid plexus cyst causing acute hydrocephalus due to herniation into the third ventricle. This case is illustrative because it describes this entity for the first time, and more importantly highlights the need to obtain a diagnosis when a patient presents with acute hydrocephalus without a clear cause.

The sea lion was successfully managed with fluid therapy, antiprotozoals, antibiotics, anti-inflammatories, antiemetics, gastroprotectants, and diuretics, but developed severe delayed hypercalcemia, a syndrome identified in humans after traumatic or exertion-induced rhabdomyolysis. Treatment with calcitonin was added to the management, and the individual recovered fully. The case emphasizes that animals with rhabdomyolysis-induced renal failure risk developing delayed hypercalcemia, which may be life threatening, and calcium levels should be closely monitored past the resolution of renal failure.

    We investigated a dose-reduced conditioning regimen consisting of treosulfan and fludarabine followed by allogeneic stem cell transplantation (SCT) in 26 patients with secondary AML or MDS. Twenty patients were transplanted from matched or mismatched unrelated donors and six from HLA-identical sibling donors. The median age of the patients was 60 years (range, 44-70). None of the patients was eligible for a standard myeloablative preparative regimen. No graft-failure was observed, and leukocyte and platelet engraftment were observed after a median of 16 and 17 days, respectively. Acute graft-versus-host disease (GvHD) grade II-IV was seen in 23% and severe grade III GvHD in 12% of the patients. No patients experienced grade IV acute GvHD. Chronic GvHD was noted in 36% of the patients, which was extensive disease in 18%. The 2-year cumulative incidence of relapse was 21%. The relapse rate was higher in patients beyond CR1 or with intermediate two or high risk MDS (P = 0.02). The treatment-related mortality at day 100 was 28%. The 2-year estimated overall and disease-free survival was 36-34%, respectively. No difference in survival was seen between unrelated and related SCT.

    The purpose of the study was to determine if abdomen/pelvis computed tomography (CT) can be safety omitted in the initial staging of a subgroup of children affected by Hodgkin Lymphoma (HL). Every participating center of A.I.E.O.P (Associazione Italiana di Ematologia ed Oncologia Pediatrica) sent local staging reports of 18F-fluorodeoxyglucose positron emission tomography (PET) and abdominal ultrasound (US) along with digital images of staging abdomen/pelvis CT to the investigation center where the CT scans were evaluated by an experienced pediatric radiologist. The local radiologist who performed the US was unaware of local CT and PET reports (both carried out after US), and the reviewer radiologist examining the CT images was unaware of local US, PET and CT reports. A new abdominal staging of 123 patients performed on the basis of local US report, local PET report, and centralized CT report was then compared to a simpler staging based on local US and PET. No additional lesion was discovered by CT in patients with abdomen/pelvis negativity in both US and PET or isolated spleen positivity in US (or US and PET), and so it seems that in the initial staging, abdomen/pelvis CT can be safety omitted in about 1/2 to 2/3 of children diagnosed with HL.

    INTRODUCTION Pneumatosis sistoides intestinalis (PSI) is a rare condition with unknown origin, defined as the appearance of gas-filled cysts in the intestinal wall. It usually occurs due to respiratory infections, tumor or collagen disease, traumas, immunosuppression. PRESENTATION OF CASE Three patients with PSI were examined that followed up and treated in our clinic. The first patient was hospitalized for emergency treatment of previously diagnosed free-air under the diaphragm. He had a defense on physical examination and free-air was detected in X-ray and abdomen CT. We decided to laparatomy and peroperatively, stenotic pylorus with an abnormally increased stomach and gas-filled cysts were seen in the terminal ileum. Antrectomy and gastrojejunostomy with partial ileum and cecum resection and end ileostomy were performed. The second patient underwent laparatomy because of intraperitoneal free-air and acute abdomen. Partial ileum and cecum resection and ileotransversostomy were performed. The third patient with intraperitoneal free-air was treated with antibiotics, oxygen treatment and bowel rest. DISCUSSION PSI is usually asymptomatic. Plain radiographs, USG, CT, upper gastrointestinal endoscopy, colonoscopy can use for diagnosis. Treatment of PSI depends on the underlying cause; include elemental diet, antibiotics, steroids, hyperbaric oxygen therapy and surgery. CONCLUSION In patients with asymptomatic and symptomatic PSI are different treat. Symptomatic PSI can be safely treated antrectomy and gastrojejunostomy with partial ileum and cecum resection.

    A 38-year-old African American woman presenting with acute abdominal pain and nonobstructive renal failure was found to have an enlarged fibroid uterus. A differential for sepsis was considered. Lab evaluation revealed an elevated creatinine and myoglobin level at 3.9 mg/dL and 2140 ng/mL, respectively. Ongoing hemodynamic instability mandated surgery for acute abdomen. A 25 cm fibroid uterus was extirpated through a total abdominal hysterectomy. Immediate improvement of acute nephropathy mirrored the postoperative decline in serum myoglobin levels. Myoglobinemia from a massive degenerating fibroid is associated with nonobstructive acute renal failure. PMID:27375910

    The benefit to be gained from carrying out computed tomography of brain and abdomen in addition to the chest has been evaluated retrospectively in 114 consecutive patients with non-small cell lung cancer who, on the basis of history, clinical examination, chest radiography, and bronchoscopy had been considered potentially operable. Computed tomography of the chest showed potentially inoperable tumour in 37 patients, of whom 25 had tumour confined to the chest. Three patients were shown to have malignant disease within the mediastinum and abdomen; five within the mediastinum and brain; and four within the mediastinum, abdomen, and brain. Computed tomography of the abdomen disclosed deposits in nine patients, but in only two were the abnormalities restricted to the abdomen. Computed tomography of the brain showed metastases in 10 patients, of whom only one had metastatic disease confined to the brain. Thus three patients had isolated deposits in the abdomen and brain. In 12 patients the identification of metastases in the abdomen and brain removed the need for mediastinoscopy. Preoperative computed tomography of the abdomen and brain detected occult metastases in 15 patients (13%) in this study. In three patients the extrathoracic abnormality proved the only contraindication to surgery, but in the other 12 it provided valuable corroborative evidence of incurability and facilitated the assessment of the mediastinal abnormality.

    2013-01-01

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

    A 66-year-old man was admitted to our hospital because of uncomplicated Stanford B acute aortic dissection. Antihypertensive therapy was initially started; however, he suddenly experienced vomiting, diarrhea, anuria, and paraparesis on the fourteenth hospital day. Contrast-enhanced computed tomography (CECT) revealed expansion of the false lumen and severe stenosis of the true lumen at the distal aortic arch, which caused malperfusion syndrome of the lower body. Percutaneous cardiopulmonary support (PCPS) was immediately initiated to restore lower body organ perfusion, and an extra-anatomic ascending-to-abdominal aorta bypass was performed with a 16-mm Dacron graft. Postoperative CECT revealed expansion and good patency of both of the true lumen and the bypass graft. His symptoms improved except for the paraparesis; he was eventually able to ambulate using a crutch after postoperative rehabilitation. PMID:27220932

    Recent evidence suggests that Ca supplements increase the risk of cardiovascular events, but the mechanism(s) by which this occurs is uncertain. In a study primarily assessing the effects of various Ca supplements on blood Ca levels, we also investigated the effects of Ca supplements on blood pressure and their acute effects on blood coagulation. We randomised 100 post-menopausal women to 1 g/d of Ca or a placebo containing no Ca. Blood pressure was measured at baseline and every 2 h up to 8 h after their first dose and after 3 months of supplementation. Blood coagulation was measured by thromboelastography (TEG) in a subgroup of participants (n 40) up to 8 h only. Blood pressure declined over 8 h in both the groups, consistent with its normal diurnal rhythm. The reduction in systolic blood pressure was smaller in the Ca group compared with the control group by >5 mmHg between 2 and 6 h (P≤0·02), and the reduction in diastolic blood pressure was smaller at 2 h (between-groups difference 4·5 mmHg, P=0·004). Blood coagulability, assessed by TEG, increased from baseline over 8 h in the calcium citrate and control groups. At 4 h, the increase in the coagulation index was greater in the calcium citrate group compared with the control group (P=0·03), which appeared to be due to a greater reduction in the time to clot initiation. These data suggest that Ca supplements may acutely influence blood pressure and blood coagulation. Further investigation of this possibility is required.

    It has been demonstrated that patients receiving mobilization techniques do not exhibit tolerance to repeated applications. However, this phenomenon has not been investigated for thoracic manipulation. Our aim was to determine if patients receiving thoracic thrust manipulation exhibit tolerance to repeated applications in acute mechanical neck pain. Forty-five patients were randomly assigned to two groups. The control group received electro- and thermotherapy for 5 sessions, and the experimental group received the same program and also received a thoracic thrust manipulation once a week for 3 consecutive weeks. Outcome measures included neck pain and cervical mobility. Within-session change scores for pain and mobility during treatment sessions #1, 3, and 5 were examined with a one-way repeated measured ANOVA. A 2-way ANOVA with session as within-subject variable and group as between-subject variable was used to compare change scores for each visit between groups to ascertain if there were significant between-group differences in within-session changes for the experimental versus the control group. The ANOVA showed that for either group the 3 within-session change scores were not significantly different (P > 0.1). The 2-way ANOVA revealed significant differences between groups for both pain and neck mobility in within-session change scores (all, P < 0.001). Change scores in each session were superior in the experimental group as compared to those in the control group. The results suggest that patients receiving thoracic manipulation do not exhibit tolerance to repeated applications with regard to pain and mobility measures in acute mechanical neck pain. Further studies should investigate the dose-response relationship of thoracic thrust manipulation in this population. PMID:20046622

    Diagnosis and treatment of common conditions in morbidly obese patients still pose a challenge to physicians and surgeons. Sometimes too much reliance is put on investigations that can lead to a misdiagnosis. This case demonstrates an obese woman admitted under the medical team with a presumed diagnosis of pneumonia, who was later found to have an acute abdomen and raised amylase, which led to an assumed diagnosis of pancreatitis. She died within 24 h of admission and post mortem confirmed the cause of death as systemic sepsis due to perforated appendicitis, with no evidence of pancreatitis. Significantly elevated serum amylase level may occur in non-pancreatitic acute abdomen.

    An 86-year-old man presented with severe pain in the upper abdomen along with fever. On physical examination, we found an arterial blood pressure of 84/43 mm Hg, a heart rate of 80 bpm and a temperature of 38.3°C. The abdomen was painful and peristalsis was absent. Empiric antibiotic therapy for sepsis was started with amoxicillin/clavulanate and gentamicin. CT scan of the abdomen revealed an emphysematous cholecystitis. Percutaneous ultrasound-guided cholecystostomy was applied. Bile cultures revealed Clostridium perfringens. Emphysematous cholecystitis is a life-threatening form of acute cholecystitis that occurs as a consequence of ischaemic injury to the gallbladder, followed by translocation of gas-forming bacteria (ie, C. perfringens, Escherichia coli, Klebsiella and Streptococci). The mortality associated with emphysematous cholecystitis is higher than in non-emphysematous cholecystitis (15% vs 4%). Therefore, early diagnosis with radiological imaging is of vital importance.

    Recent clinical trials of primary and secondary prevention of cardiovascular disease have demonstrated that lowering plasma cholesterol decreases the incidence of coronary heart disease in patients with elevated plasma cholesterol. However, it is not known whether patients with established coronary artery disease and normal plasma cholesterol can be benefited. Several previous prevention trials reviewed in this report found that patients who had plasma cholesterol levels at baseline in the upper portion of the eligibility range (e.g., greater than 240 mg/dl) received greater benefit from hypolipidemic diet or drug therapy than patients who had lower plasma cholesterol levels at baseline. The recent availability of drugs that are more potent and less prone to cause adverse reactions than previous regimens permits this important question to be addressed. The Cholesterol and Recurrent Events trial is testing whether pravastatin, a hydroxymethylglutaryl coenzyme A reductase inhibitor, will decrease the sum of fatal coronary heart disease and nonfatal myocardial infarction (MI) in patients who have recovered from a MI and who have normal total cholesterol levels. Fatal cardiovascular disease and total mortality are important secondary end points. The trial is enrolling 4,000 men and women from 80 centers throughout North America, age 21 to 75 years, who have survived MI for 3 to 20 months, who have plasma total cholesterol less than 240 mg/dl (6.2 mmol/liter) and low-density cholesterol of 115 to 174 mg/dl (3.0 to 4.5 mmol/liter), and who are representative of the general population of patients with MI. Patients are randomized to either active or inactive drug therapy. Active therapy consists of pravastatin, 40 mg/day, designed to achieve an average decrease in low-density lipoprotein cholesterol of approximately 30%, and an increase in high-density lipoprotein of 5%. The average duration of follow-up will be greater than or equal to 5 years. To protect against a lower

    Purpose This study evaluates the diagnostic accuracy of [F-18]-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) of the chest/upper abdomen compared to the generally performed scan from head to upper thighs, for staging and management of (suspected) lung cancer in patients with no history of malignancy or complaints outside the thorax. Methods FDG-PET/CT scans of 1059 patients with suspected or recently proven lung cancer, with no history of malignancy or complaints outside the thorax, were analysed in a retrospective multi-centre trial. Suspect FDG-avid lesions in the chest and upper abdomen, the head and neck area above the shoulder line and in the abdomen and pelvis below the caudal tip of the liver were noted. The impact of lesions detected in the head and neck area and abdomen and pelvis on additional diagnostic procedures, staging and treatment decisions was evaluated. Results The head and neck area revealed additional suspect lesions in 7.2%, and the abdomen and pelvis in 15.8% of patients. Imaging of the head and neck area and the abdomen and pelvic area showed additional lesions in 19.5%, inducing additional diagnostic procedures in 7.8%. This resulted in discovery of additional lesions considered malignant in 10.7%, changing patient management for lung cancer in 1.2%. In (suspected) lung cancer, PET/CT limited to the chest and upper abdomen resulted in correct staging in 98.7% of patients, which led to the identical management as full field of view PET in 98.8% of patients. Conclusion High value of FDG-PET/CT for staging and correct patient management is already achieved with chest and upper abdomen. Findings in head and neck area and abdomen and pelvis generally induce investigations with limited or no impact on staging and treatment of NSCLC, and can be interpreted accordingly. PMID:27556809

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

    Background The objective of this study was to investigate the efficacy, safety, and subject satisfaction of the calcium hydroxylapatite-based dermal filler Radiesse® in a novel body vectoring technique to correct skin flaccidity in the thighs, abdomen, and brachial zones. Methods Female subjects with self-evaluated flaccidity scores ≥3 on a 6-point scale (0, no flaccidity; 5, very severe flaccidity) in the zones of interest were included. Radiesse was injected according to predesigned vector maps (3 mL per thigh, 1.5 mL per hemiabdomen or brachial zone). Clinical assessments (skin density and thickness) were made by an independent reviewer at an exact position before and 5 weeks after treatment using a cutometer and an ultrascan. Subjects rated skin flaccidity before and 5 weeks after treatment on the 6-point scale and performed a pinch test to self-assess changes in skin thickness. All adverse events were recorded. Results Twenty females (aged 28–67 years) were enrolled, contributing 36 treatment zones. Across all zones, 78% of flaccidity measurements improved after treatment. Improvements in skin flaccidity were most common in the thighs (82% of cases). An improvement in skin density versus baseline was observed in the majority across all zones, most frequently in the abdomen (88% of cases). Skin thickness in each zone also improved versus baseline for the majority, most frequently in the thighs (88% of cases). Mean self-assessed flaccidity scores at baseline were 3.6 (thighs), 3.7 (abdomen), and 3.8 (brachial zone), and 2.6, 2.7, and 3.0, respectively, posttreatment. All subjects reported a positive pinch test. In total, 47.0% of subjects had bruising after treatment, which resolved within a week. No serious adverse events were reported. Conclusion Using this novel technique, Radiesse had notable results on skin flaccidity, density and thickness in the thighs, abdomen, and brachial zones, and was well tolerated. PMID:26056483

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

    The open abdomen is an ongoing challenge for professionals engaged in its treatment. The change in the integrity of the abdominal wall, the loss of fluids, heat and proteins and contamination of the wound are the main problems. The objective of this article is to describe our experience using the abdominal dressing vacuum-assisted closure therapy in treatment of the open abdomen. Since December 2006, all patients requiring treatment with the open abdomen technique have been treated with the abdominal dressing system and vacuum-assisted closure therapy (VAC(®) KCI, San Antonio, USA). The results obtained with this technique in non traumatic patients are analysed herein. The abdominal dressing system was used on 46 patients in the period between January 2006 and December 2009, with a mean 63 years old (29-80), with a gender distribution of 33 men (72%) and 13 women (28%). Closure of the abdominal wall was possible in 24 patients, 5 of which were primary in the recent postoperative phase, 5 had primary suture of the fascia and application of the supra-aponeurotic prosthesis and 14 had closure of the abdominal wall with a composite polytetrafluoroethylene (PTFE) and polypropylene mesh. Second intention closure took place in the remaining 22 patients (48%), as their conditions did not allow primary closure. The mean treatment time with abdominal dressing was 26 days (6-92) with an average of eight changes per patient. The abdominal dressing topical negative pressure system is a useful option for consideration in the event of needing to leaves the abdomen open. It stabilises the abdominal wall and quantifies and collects exudate from the wound, protects the intra-abdominal viscera and keeps the fascia intact and the cutaneous plane for subsequent closure of the wall.

    A new device for reducing the amplitude of breathing motion by pressing a patient's abdomen using an air-injected blanket (AIB) for external beam radiation treatments has been designed and tested. The blanket has two layers sealed in all four sides similar to an empty pillow made of urethane. The blanket is spread over the patient's abdomen with both ends of the blanket fixed to the sides of the treatment couch or a baseboard. The inner side, or patient side, of the blanket is thinner and expands more than the outer side. When inflated, the blanket balloons and effectively puts an even pressure on the patient's abdomen. Fluoroscopic observation was performed to verify the usefulness of AIB for patients with lung, breast cancer, or abdominal cancers. Internal organ movement due to breathing was monitored and measured with and without AIB. With the help of AIB, the average range of diaphragm motion was reduced from 2.6 to 0.7 cm in the anterior-to-posterior direction and from 2.7 to 1.3 cm in the superior-to-inferior direction. The motion range in the right-to-left direction was negligible, for it was less than 0.5 cm. These initial testing demonstrated that AIB is useful for reducing patients' breathing motion in the thoracic and abdominal regions comfortably and consistently.

    Radionuclide hepatobiliary imaging with Tc-99m IDA is a useful procedure for the diagnosis of acute cholecystitis. Visualization of the gallbladder essentially rules out acute cholecystitis. Nonvisualization suggest acute cholecystitis but may also be associated with chronic gallbladder disease or other conditions. The authors recently observed five patients in whom a rim of increased parenchymal liver activity was seen adjacent to the gallbladder fossa. All five patients had acute gangrenous cholecystitis. The rim of increased activity appears to be a useful secondary sign of acute cholecystitis.

    Major replantation of a traction avulsion amputation is undertaken with the goal of not only the reestablishment of circulation, but also functional outcome. This type of amputation is characterized by different levels of soft-tissue divisions involving crushing, traction, and avulsion injuries to various structures. Between 1985 and 1998, 27 cases were referred for secondary reconstruction following amputation of the upper extremity involving both arm and forearm. Replantation was performed by at least 12 qualified plastic surgeons using different approaches and management, resulting in different outcomes. Initial replantation management significantly affects the later reconstruction. For comparing studies and prognostic implications, the authors propose a new classification according to the level of injury to muscles and innervated nerves: type I, amputation at or close to the musculotendinous aponeurosis with muscles remaining essentially intact; type II, amputation within the muscle bellies but with the proximal muscles still innervated; type III, amputation involving the motor nerve or neuromuscular junction, thereby causing total loss of muscle function; and type IV, amputation through the joint; i.e., disarticulation of the elbow or shoulder joint. Some patients required further reconstruction for functional restoration after replantation, but some did not. Through this retrospective study based on the proposed classification system, prospective guidelines for the management of different types of traction avulsion amputation are provided, including the value of replantation, length of bone shortening, primary or delayed muscle or nerve repair, necessity of fasciotomy, timing for using free tissue transfer for wound coverage, and the role of functioning free muscle transplantation for late reconstruction. The final functional outcome can also be anticipated prospectively through this classification system.

    Introduction: Knowledge on epidemiology of the disease in the contemporary world will help to develop appropriate strategies to curtail the transmission during an outbreak. This study was carried out during an outbreak of conjunctivitis in selected areas of Puducherry, South India, to assess the attack rate of conjunctivitis, identify factors associated with developing conjunctivitis and calculate household secondary attack rate (HSAR) of conjunctivitis and its correlates. Methodology: During December 2014, a community-based survey was conducted in a selected urban and rural area in Puducherry, South India. Simple random sampling was used to select primary sampling units and systematic sampling to select households. All individuals in the selected households were studied. A questionnaire was used to obtain data on sociodemographic characteristics, conjunctivitis during September-November, 2014, and number of household contacts who developed conjunctivitis within 7 days of index case. The attack rate and HSAR of conjunctivitis was expressed as percentage. Multivariate logistic regression was used to find factors independently associated with developing conjunctivitis and also 100% HSAR. Results: Of 3193 study participants from 772 households, 509 (15.9%, 95% confidence interval 14.7-17.2%) had an attack of conjunctivitis during the reference period. Of the 772 households, 218 (28.2%) had at least one case of conjunctivitis. Of 218 households, 33 (15.1%) households had 100% HSAR. Lower age, not being unemployed, low socioeconomic status, and residing in rural area were independently associated with developing conjunctivitis. Index case being male and living in a household with ≥5 members were independently associated with 100% HSAR. Conclusion: In the outbreak under study, more than one-fourth of households had at least one case of conjunctivitis and about one in every six individuals had an attack of conjunctivitis.

    Streptomyces organisms are soil inhabitants rarely causing nonmycetomic infections. We describe a case of secondary peritonitis caused by Streptomyces viridis in a chronic alcoholic patient who presented with fever, abdominal distension, and pain in the abdomen. The most likely source of infection was by inoculation through multiple paracenteses, done for treatment of ascites, before the patient came to our health care center. This is the second case report of Streptomyces peritonitis and the first case caused by Streptomyces viridis, which is usually found in the soil in our geographic region. PMID:22337982

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    Background: Acute appendicitis is the most common cause of acute abdomen. Approximately 7% of the population will be affected by this condition during full life. The development of AIR score may contribute to diagnosis associating easy clinical criteria and two simple laboratory tests. Aim: To evaluate the score AIR (Appendicitis Inflammatory Response score) as a tool for the diagnosis and prediction of severity of acute appendicitis. Method: Were evaluated all patients undergoing surgical appendectomy. From 273 patients, 126 were excluded due to exclusion criteria. All patients were submitted o AIR score. Results: The value of the C-reactive protein and the percentage of leukocytes segmented blood count showed a direct relationship with the phase of acute appendicitis. Conclusion: As for the laboratory criteria, serum C-reactive protein and assessment of the percentage of the polymorphonuclear leukocytes count were important to diagnosis and disease stratification.

    Acute pancreatitis is an acute inflammatory disease of the pancreas that may also involve surrounding tissues or remote organs. The Atlanta classification of acute pancreatitis was introduced in 1992 and divides patients into mild and severe groups based on clinical and biochemical criteria. Recently, the terminology and classification scheme proposed at the initial Atlanta Symposium have been reviewed and a new consensus statement has been proposed by the Acute Pancreatitis Classification Working Group. Generally, imaging is recommended to confirm the clinical diagnosis, investigate the etiology, and grade the extend and severity of the acute pancreatitis. Ultrasound is the first-line imaging modality in most centers for the confirmation of the diagnosis of acute pancreatitis and the ruling out of other causes of acute abdomen, but it has limitations in the acute clinical setting. Computed tomography not only establishes the diagnosis of acute pancreatitis, but also enables to stage severity of the disease. Magnetic resonance imaging has earned an ever more important role in the diagnosis of acute pancreatitis. It is especially useful for imaging of patients with iodine allergies, characterizing collections and assessment of an abnormal or disconnected pancreatic duct. The purpose of this review article is to present an overview of the acute pancreatitis, clarify confusing terminology, underline the role of ultrasound, computed tomography and magnetic resonance imaging according to the proper clinical context and compare the advantages and limitations of each modality.

    Hypertension is a common disease and a crucial predisposing factor of cardiovascular diseases. Approximately 10% of hypertensive patients are secondary hypertension, a pathogenetic factor of which can be identified. Secondary hypertension consists of endocrine, renal, and other diseases. Primary aldosteronism, Cushing's syndrome, pheochromocytoma, hyperthyroidism, and hypothyroidism result in endocrine hypertension. Renal parenchymal hypertension and renovascular hypertension result in renal hypertension. Other diseases such as obstructive sleep apnea syndrome are also very prevalent in secondary hypertension. It is very crucial to find and treat secondary hypertension at earlier stages since most secondary hypertension is curable or can be dramatically improved by specific treatment. One should keep in mind that screening of secondary hypertension should be done at least once in a daily clinical practice. PMID:26619670

    The purpose of this study is to develop a method for estimating patient-specific dose from abdomen-pelvis CT examinations and to investigate dose variation across patients in the same weight group. Our study consisted of seven pediatric patients in the same weight/protocol group, for whom full-body computer models were previously created based on the patients' CT data obtained for clinical indications. Organ and effective dose of these patients from an abdomen-pelvis scan protocol (LightSpeed VCT scanner, 120-kVp, 85-90 mA, 0.4-s gantry rotation period, 1.375-pitch, 40-mm beam collimation, and small body scan field-of-view) was calculated using a Monte Carlo program previously developed and validated for the same CT system. The seven patients had effective dose of 2.4-2.8 mSv, corresponding to normalized effective dose of 6.6-8.3 mSv/100mAs (coefficient of variation: 7.6%). Dose variations across the patients were small for large organs in the scan coverage (mean: 6.6%; range: 4.9%-9.2%), larger for small organs in the scan coverage (mean: 10.3%; range: 1.4%-15.6%), and the largest for organs partially or completely outside the scan coverage (mean: 14.8%; range: 5.7%-27.7%). Normalized effective dose correlated strongly with body weight (correlation coefficient: r = -0.94). Normalized dose to the kidney and the adrenal gland correlated strongly with mid-liver equivalent diameter (kidney: r = -0.97; adrenal glands: r = -0.98). Normalized dose to the small intestine correlated strongly with mid-intestine equivalent diameter (r = -0.97). These strong correlations suggest that patient-specific dose may be estimated for any other child in the same size group who undergoes the abdomen-pelvis scan.

    Freons are generally considered to be minimally toxic. There are no reports in the literature of Freons causing secondary arterial hypertension. We report two cases of acute, massive Freon exposure that preceded secondary arterial hypertension. We hypothesize that the arterial hypertension was precipitated by renal proximal tubular damage, although several other mechanisms are possible.

    Acute abdomen is one of the most common clinical conditions requiring a radiological investigation. Ultrasound is the primary modality of choice which can diagnose some of the common causes of acute abdomen. However, sometimes the underlying cause for the pain is far more complicated than expected mandating a high degree of suspicion to suggest further investigation with contrast enhanced computed tomography or magnetic resonance imaging. Here, we have compiled a comprehensive series of selected cases to highlight the conditions which can be easily overlooked unless carefully sought for. This article also emphasizes the importance of multimodality approach to arrive at the final diagnosis with an increased overall diagnostic accuracy which in turn improves patient management and prognosis.

  16. Association between brain imaging signs, early and late outcomes, and response to intravenous alteplase after acute ischaemic stroke in the third International Stroke Trial (IST-3): secondary analysis of a randomised controlled trial

    PubMed Central

    2015-01-01

    Summary Background Brain scans are essential to exclude haemorrhage in patients with suspected acute ischaemic stroke before treatment with alteplase. However, patients with early ischaemic signs could be at increased risk of haemorrhage after alteplase treatment, and little information is available about whether pre-existing structural signs, which are common in older patients, affect response to alteplase. We aimed to investigate the association between imaging signs on brain CT and outcomes after alteplase. Methods IST-3 was a multicentre, randomised controlled trial of intravenous alteplase (0·9 mg/kg) versus control within 6 h of acute ischaemic stroke. The primary outcome was independence at 6 months (defined as an Oxford Handicap Scale [OHS] score of 0–2). 3035 patients were enrolled to IST-3 and underwent prerandomisation brain CT. Experts who were unaware of the random allocation assessed scans for early signs of ischaemia (tissue hypoattenuation, infarct extent, swelling, and hyperattenuated artery) and pre-existing signs (old infarct, leukoaraiosis, and atrophy). In this prespecified analysis, we assessed interactions between these imaging signs, symptomatic intracranial haemorrhage (a secondary outcome in IST-3) and independence at 6 months, and alteplase, adjusting for age, National Institutes of Health Stroke Scale (NIHSS) score, and time to randomisation. This trial is registered at ISRCTN.com, number ISRCTN25765518. Findings 3017 patients were assessed in this analysis, of whom 1507 were allocated alteplase and 1510 were assigned control. A reduction in independence was predicted by tissue hypoattenuation (odds ratio 0·66, 95% CI 0·55–0·81), large lesion (0·51, 0·38–0·68), swelling (0·59, 0·46–0·75), hyperattenuated artery (0·59, 0·47–0·75), atrophy (0·74, 0·59–0·94), and leukoaraiosis (0·72, 0·59–0·87). Symptomatic intracranial haemorrhage was predicted by old infarct (odds ratio 1·72, 95% CI 1·18–2·51), tissue

    The term "acute interstitial pneumonia" (AIP) describes an idiopathic clinicopathological condition, characterized clinically by an interstitial lung disease causing rapid onset of respiratory failure, which is distinguishable from the other more chronic forms of interstitial pneumonia. It is synonymous with Hamman-Rich syndrome, occurring in patients without pre-existing lung disease. The histopathological findings are those of diffuse alveolar damage. AIP radiologically and physiologically resembles acute respiratory distress syndrome (ARDS) and is considered to represent the small subset of patients with idiopathic ARDS. It is frequently confused with other clinical entities characterized by rapidly progressive interstitial pneumonia, especially secondary acute interstitial pneumonia, acute exacerbations and accelerated forms of cryptogenic fibrosing alveolitis . Furthermore, many authors use the above terms, both erroneously and interchangeably. It has a grave prognosis with >70% mortality in 3 months, despite mechanical ventilation. This review aims to clarify the relative clinical and pathological issues and terminology.

    La rate ectopique est une entité rare dont l'incidence est mal connue. La torsion de son pédicule est une complication grave, qui doit bénéficier d'un diagnostic précoce; évitant ainsi la splénectomie surtout chez des patients jeunes. Nous rapportons le cas d'une patiente âgée de 39 ans; admise aux urgences dans un tableau d'abdomen aigu chirurgical, l'examen clinique, l’échographie et la tomodensitométrie abdominale ont contribué au diagnostic de torsion d'une rate ectopique en position hypogastrique, la splénectomie a été réalisée devant la découverte peropératoire de taches de nécrose sur la rate tordue. Le diagnostic de torsion d'une rate ectopique doit être suspecté devant l'association d'un abdomen aigu et la palpation d'une masse abdominale. L’échographie et la tomodensitométrie abdominale confirment le diagnostic. Le traitement est chirurgical; il consiste en une splénopexie qui est plus approprié. En présence de nécrose, la splénectomie doit être réalisée aussi bien par voie laparoscopique que par laparotomie. PMID:22655096

  1. Swordfish bill injury involving abdomen and vertebral column: case report and review

    PubMed Central

    2010-01-01

    Background Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks. Case presentation In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma. Conclusions Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature. PMID:20969749

    The present study explored the relationship between the regional Cold-Heat sensation, the key indicator of the Cold-Heat patterns in traditional East Asian medicine (TEAM), and various biomarkers in Korean population. 734 apparently healthy volunteers aged 20 years and older were enrolled. Three scale self-report questions on the general thermal feel in hands, legs, and abdomen were examined. We found that 65% of women tended to perceive their body, particularly their hands and legs, to be cold, versus 25% of men. Energy expenditure and temperature load at resting state were lower in women, independently of body mass index (BMI). Those with warm hands and warm legs had a 0.74 and 0.52 kg/m2 higher BMI than those with cold hands and cold legs, respectively, regardless of age, gender, and body weight. Norepinephrine was higher, whereas the dynamic changes in glucose and insulin during an oral glucose tolerance test were lower in those with cold extremities, particularly hands. No consistent differences in biomarkers were found for the abdominal dimension. These results suggest that gender, BMI, the sympathetic nervous system, and glucose metabolism are potential determinants of the Cold-Heat sensation in the hands and legs, but not the abdomen.

    Portal vein (PV) thrombosis (PVT) is a rare condition with development of thrombosis in the PV and its branches. Further extension to the splenic and superior mesenteric vein (SMV) causes intestinal infarction, with a reported mortality of up to 50%. A variety of treatments for PVT exist including anticoagulation, thrombolysis, surgical thrombectomy, insertion of shunts, bypass surgery, and liver transplantation. We experienced a case of successfully treated by surgical thrombectomy with direct thrombolysis into the thrombosed-PV and SMV. A 31-year-old male presented worsening abdominal pain for one week. Preoperative contrast enhanced computed tomography scan revealed complete PVT extending to splenic vein and SMV. The PV was accessed surgically and opened by thrombectomy; visual inspection confirmed proximal and distal flow. Urokinase was administered directly into the inferior mesenteric vein with successful decrease in thrombus burden. The complete angiography showed complete dissolution of thrombosis in PV and SMV.

    BACKGROUND Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil's disease. CASE REPORT A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient's condition drastically improved after initiation of doxycycline. On subsequent days, the patient's Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. CONCLUSIONS As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis presenting as Weil's disease is a common cause of renal and hyperbilirubinemia in endemic areas. Often, as was the case for our patient where the time from presentation to acute

    Introduction Intestinal malrotation refers to the partial or complete failure of rotation of midgut around the superior mesenteric vessels in embryonic life. Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. Presentation of case 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating “whirpool sign”. Discussion Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. Conclusion Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality. PMID:27015011

    Abdominal pain with dengue fever can be a diagnostic challenge. Typically, pain is localised to the epigastric region or associated with hepatomegaly. Patients can also present with acute abdomen. We report a case of a girl with dengue fever and right iliac fossa pain. The diagnosis of acute appendicitis was made only after four days of admission. An appendicular mass and a perforated appendix was noted during appendectomy. The patient recovered subsequently. Features suggestive of acute appendicitis are persistent right iliac fossa pain, localised peritonism, persistent fever and leucocytosis. Repeated clinical assessment is important to avoid missing a concurrent diagnosis like acute appendicitis. PMID:27326951

    Acute pancreatitis during pregnancy is a rare event, and can be associated with high maternal mortality and fetal loss. Gallstone disease is thought to be the most common causative factor of acute pancreatitis, but, in many cases, the cause remains unclear. We report a case of a 36-year-old woman at 35 wk of gestation, who presented with severe pain confined to the upper abdomen and radiating to the back. The patient was diagnosed with acute idiopathic pancreatitis, which was managed conservatively; she recovered within several days and then delivered a healthy baby. Therefore it is important to consider acute pancreatitis when a pregnant woman presents with upper abdominal pain, nausea and vomiting in order to improve fetal and maternal outcomes for patients with acute pancreatitis.

    Increased of proinflammatory cytokines levels, including interleukin-8 (IL-8) and tumor necrosis factor-alpha (TNF-alpha) on severe acute pancreatitis causes vasodilatation, increased permeability of the wall, accumulation of fluid in lung tissue and pleural sinuses. Transudate from acute parapancreatyc clusters of hot liquid and abdomen falls into the chest cavity through microscopic defects in the diaphragm due to the formation of pathological pleural-peritoneal connections or the relevant pressure gradient between the abdominal and pleural cavities. Remediation and removal of acute parapancreatyc clusters combined with the use of a multicomponent drug infusion therapy Cytoflavin provide a reduction in the frequency of pulmonary complications of acute pancreatitis from 48.3 to 31.0%. Use of the drug Cytoflavin reduces the severity of endogenous intoxication and mortality from acute lung injury from 12.9 to 6.1%. PMID:26521460

    Acute rhinosinusitis is a common illness in children. Viral upper respiratory tract infection is the most common presentation of rhinosinusitis. Most children resolve the infection spontaneously and only a small proportion develops a secondary bacterial infection. The proper choice of antibiotic therapy depends on the likely infecting pathogens, bacterial antibiotic resistance, and pharmacologic profiles of antibiotics. Amoxicillin-clavulanate is currently recommended as the empiric treatment in those requiring antimicrobial therapy. Isolation of the causative agents should be considered in those who failed the initial treatment. In addition to antibiotics, adjuvant therapies and surgery may be used in the management of acute bacterial rhinosinusitis.

This topic is increasingly being discussed as e.g. more than 50% of Slovak population die on atherosclerotic complications. According to etiology we distinguish primary dyslipidemias with strictly genetic background and secondary ones with origin in other disease or pathological state. Secondary dyslipidemias accompany various diseases, from common (endocrinopathies, renal diseases etc) to rare ones (thesaurismosis etc.) and represents one of symptoms of these diseases. Apart from particular clinical follow up of diagnosed dysipidemias, basic screening and secondary causes as well as treatment due to updated guidelines is recuired. In this review we present the most frequent dyslipidemias of clinical practice.

    A suspected case of localized visceral hyperpigmentation was described for a breed of broiler in China. Using optical microscopy, the accumulation of pigments in the abdominal skin and visceral peritoneum was observed. Electron microscopy was used to further study the ultrastructure of the pigmented peritoneum, and pigment granules resembling melanosomes at different stages were found, and melanocytes were present in this tissue. Infrared spectroscopy was used to analyze the physical-chemical properties of pigments extracted from these broilers. Using synthetic melanin as a reference and the melanin from the peritoneum of Silkie fowls as a control, the pigments in the peritonea of these broilers were found to be melanin, and it had a chemical structure similar to that of melanin from the Silkie fowl peritoneum. In this way, the black abdomens of these broilers were found to have been caused by accumulation of melanin produced by melanocytes in visceral peritonea.

    2014-05-01

    Recent technologic advances in computed tomography (CT)--enabling the nearly simultaneous acquisition of clinical images using two different x-ray energy spectra--have sparked renewed interest in dual-energy CT. By interrogating the unique characteristics of different materials at different x-ray energies, dual-energy CT can be used to provide quantitative information about tissue composition, overcoming the limitations of attenuation-based conventional single-energy CT imaging. In the past few years, intensive research efforts have been devoted to exploiting the unique and powerful opportunities of dual-energy CT for a variety of clinical applications. This has led to CT protocol modifications for radiation dose reduction, improved diagnostic performance for detection and characterization of diseases, as well as image quality optimization. In this review, the authors discuss the basic principles, instrumentation and design, examples of current clinical applications in the abdomen and pelvis, and future opportunities of dual-energy CT.

    The basal ant Dinoponera (Hymenoptera: Ponerinae) has lost the morphologic queen caste so that all females may be potential reproductive individuals, and the nestmate recognition results from cuticular hydrocarbons cues. However, data about the origin of that substance in Ponerinae ants are scarce. This study reports the occurrence of epidermal glands in the abdomen of the ant Dinoponera lucida. In this ant, the epidermis of the abdominal sternites has tall cells with well-developed nucleus contrasting with flattened and collapsed epidermis in the tergites, suggesting a glandular function in the epidermis of the sternites. The possible role of the glandular epidermis in the synthesis of cuticular hydrocarbons for the nestmate recognition is discussed. PMID:18816599

    Diagnosis of Strongyloides stercoralis hyperinfection can be a challenge. The key to a timely diagnosis is to have a high index of suspicion. We present a rare case of a 36-year-old human immunodeficiency virus negative male patient, who was on multidrug therapy for lepromatous leprosy and was treated for type 2 lepra reactions with steroids in the past. The patient presented with vomiting and pain abdomen, persistent hyponatremia, and terminal hypoglycemia. He had features of malnutrition and had a rapid downhill course following admission. A diagnosis of S. stercoralis hyperinfection with sepsis and multiorgan failure, adrenal hemorrhage, and syndrome of inappropriate antidiuretic hormone secretion was established on a postmortem examination.

    Dual energy CT (DECT) is a new technique that allows differentiation of materials and tissues based on CT density values derived from two synchronous CT acquisitions at different tube potentials. With the introduction of a new dual source CT system, this technique can now be used routinely in abdominal imaging. Potential clinical applications include evaluation of renal masses, liver lesions, urinary calculi, small bowel, pancreas, and adrenal glands. In CT angiography of abdominal aortic aneurysms, dual energy CT techniques can be used to remove bones from the datasets, and virtual unenhanced images allow differentiation of contrast agent from calcifying thrombus in patients with endovascular stents. This review describes potential applications, practical guidelines, and limitations of dual energy CT in the abdomen.

    In migrant countries, ethnic origin may represent a complex of cultural, behavioral and possibly genetic differences. These have been shown to influence acute myocardial infarction (AMI) incidence. How ethnic origin may affect survival after AMI is unknown. Data from 5,692 patients included in the Secondary Prevention Reinfarction Israeli Nifedipine Trial (SPRINT) registry were analyzed. Patients were divided into eight different ethnic groups, according to birthplaces from five continents, representing major socio-economic and possibly some genetic variation. Mortality was analyzed after adjustment for baseline characteristics known to predict death from coronary artery disease (CAD) using Jews born in Israel as a reference. The odds ratio for in-hospital mortality was higher in women than in men, but unrelated to ethnic origin. The odds ratio for men ranged between 1.08 (95% confidence interval (CI): 0.67-1.73) for Jews born in Eastern Europe and 1.84 (95% CI: 1.07-3.15) for counterparts born in the Middle East. The odds ratio for women ranged between 0.73 in Jews born in Central Europe (95% CI: 0.35-1.50) and 1.45 (95% CI: 0.76-3.15) for Jewish women born in the Balkan countries. Among 4,686 patients surviving the hospital phase, long-term mortality rates (mean follow-up 7.1 +/- 3.5 years) were 43.3% in men and 57.6% in women. Among 3,586 surviving men, the adjusted risk ratios for 10-year mortality varied between 0.92 (95% CI: 0.72-1.18) for men born in Romania and 1.49 (95% CI: 1.07-2.09) for Israeli born Arabs. The variation among men is within the limits of statistical error. However, among 1,100 surviving women, the risk ratio for 10-year mortality differed significantly, from as low as 1.43 (95% CI: 0.84-2.41) in Jewish women born in Central Europe to as high as 2.83 (95% CI: 1.67-4.79) in counterparts born in the Middle East. The latter observations were consistent with the mortality after 3 years. Thus, ethnic origin of Israelis marginally influenced the

    Purpose: Whole Abdomen Radiation Therapy (WART) is used in the treatment of desmoplastic small round cell tumors as well as other tumors with peritoneal dissemination. Intensity modulated radiation therapy (IMRT) is conventionally used to cover the multiple planning target volumes (PTVs) while sparing nearby critical structures, but this approach often requires two isocenters and ≥20 individual treatment fields. Four-field volumetric arc therapy (VMAT) can produce clinically similar treatment plans with the potential to reduce treatment time substantially. Here we examine treatment times and plan robustness for patients undergoing WART. Methods: Twenty patients undergoing WART at our institution were included in this study. Twelve IMRT and 8 VMAT plans utilized upper and lower abdominal isocenters and met similar dose constraints. Treatment times were tabulated from start of daily kV imaging to beam delivery end. Daily treatment couch coordinates were also recorded. From these couch coordinates, difference between actual and planned separation between isocenters was computed. Plan robustness with regard to PTV coverage within the region of field overlap was analyzed for 3 VMAT and 3 IMRT plans assuming a 2σ deviation in isocenter location. Results: The average treatment time for VMAT was 15 minutes shorter than for IMRT (27 minutes vs. 42 minutes). The average deviation in isocenter separation was 0.0 – 0.1 cm in each direction, with a standard deviation of 0.2 – 0.3 cm. Compared with IMRT plans, VMAT plans showed similar loss in PTV coverage for increasing isocenter displacement and similar dose inhomogeneity with decreasing isocenter displacement. Conclusion: Use of VMAT results in substantial time-savings for 2-isocenter whole abdomen radiotherapy plans. VMAT plans show robustness similar to IMRT with respect to isocenter displacement. VMAT should be considered for these very complicated treatments to minimize risk of patient movement during therapy and

    Small bowel perforation is a unique, serious complication during endometrial biopsy. The authors report a case of a double uterine-ileal perforation totally managed by primary laparoscopic repair. A 63-year-old female was admitted with acute abdomen 2 days after an endometrial curettage. Abdominal X-ray shows signs of pneumoperitoneum. Emergency diagnostic laparoscopy was performed and a uterine-ileal perforation was identified. Repair was accomplished by a totally laparoscopic intracorporeally suturing of the 2 breaches. Postoperative course showed only a delayed ileus and the patient was discharged after 5 days with no complications. When acute abdomen arises following uterine biopsy, a potential iatrogenic intestinal laceration always has to be ruled out. Laparoscopic approach is a quick and safe technique in these cases. Totally laparoscopic primary closure of the iatrogenic ileal laceration may be accomplished with low morbidity. PMID:25692425

    Electron spin resonance (ESR) imaging can visualize the distribution of free radicals in living systems according to their concentrations. However, the application of ESR imaging to living animals has not been well established. Using a rapid field scan L-band ESR imaging system, we have successfully obtained two-dimensional ESR projection (xz-plane projection) and three-dimensional ESR-CT (trans-axial section along the y-axis) images of the abdomen of living mice after an injection of 3-carbamoyl-2,2,5,5-tetramethylpyrrolidine-1-oxyl (carbamoyl-PROXYL) into the tail vein. The in vivo two-dimensional ESR projection imaging clearly visualized the carbamoyl-PROXYL distribution and the rapid decay process in the abdomen. Because among the viscera, the liver is most abundantly associated with a blood volume, the outline of the image can be composed mainly of this organ. We therefore attempted to find whether there will be a difference in spatiotemporal dynamics of carbamoyl-PROXYL in the abdomens between the control and the mice with liver damage by two-dimensional ESR projection. In the control mice, carbamoyl-PROXYL was almost completely eliminated from the abdomen within 5 minutes after administration. On the other hand, in mice with carbon tetrachloride-damaged livers, the decay of carbamoyl-PROXYL was markedly prolonged. Even at 5 min after administration, carbamoyl-PROXYL remained clearly visible in the abdomen. In vivo three-dimensional ESR-CT imaging showed an even distribution of carbamoyl-PROXYL throughout the whole liver, which corresponded well with the images of trans-axial sections of the murine abdomen. We have succeeded in displaying two-dimensional ESR projection and three-dimensional ESR-CT images of carbamoyl-PROXYL distribution and clearance in the abdomen of a living animal. The ESR-CT imaging technique is considered to be a powerful new tool for noninvasive investigations of the in vivo spatiotemporal dynamics of free radical distribution and

    Secondary osteoporosis is less common than primary osteoporosis. It may be suspected in patients who present with a fragility fracture despite having no risk factors for osteoporosis. In addition, secondary osteoporosis should be considered if the bone density Z-score is -2.5 or less. Consider the fracture site and presence of other clinical clues to guide investigations for an underlying cause. The tests to use are those that are indicated for the suspected cause. Baseline investigations include tests for bone and mineral metabolism (calcium, phosphate, alkaline phosphatase, 25-hydroxyvitamin D, parathyroid hormone), liver and kidney function, full blood count and thyroid-stimulating hormone. More detailed testing may be required in patients with severe osteoporosis.

    Background The aim was to determine the incidence of seed migration not only to the chest, but also to the abdomen and pelvis after transperineal interstitial prostate brachytherapy with loose 125I seeds. Methods We reviewed the records of 267 patients who underwent prostate brachytherapy with loose 125I seeds. After seed implantation, orthogonal chest radiographs, an abdominal radiograph, and a pelvic radiograph were undertaken routinely to document the occurrence and sites of seed migration. The incidence of seed migration to the chest, abdomen, and pelvis was calculated. All patients who had seed migration to the abdomen and pelvis subsequently underwent a computed tomography scan to identify the exact location of the migrated seeds. Postimplant dosimetric analysis was undertaken, and dosimetric results were compared between patients with and without seed migration. Results A total of 19,236 seeds were implanted in 267 patients. Overall, 91 of 19,236 (0.47%) seeds migrated in 66 of 267 (24.7%) patients. Sixty-nine (0.36%) seeds migrated to the chest in 54 (20.2%) patients. Seven (0.036%) seeds migrated to the abdomen in six (2.2%) patients. Fifteen (0.078%) seeds migrated to the pelvis in 15 (5.6%) patients. Seed migration occurred predominantly within two weeks after seed implantation. None of the 66 patients had symptoms related to the migrated seeds. Postimplant prostate D90 was not significantly different between patients with and without seed migration. Conclusion We showed the incidence of seed migration to the chest, abdomen and pelvis. Seed migration did not have a significant effect on postimplant prostate D90. PMID:21974959

    Endometriosis is a quite common pathology, however, intestinal endometriosis is a rare condition, which typically occurs with chronic symptoms. Its acute presentation is very infrequent. We herein report four cases of intestinal endometriosis, in which the clinical debut occurred acutely: two as an acute small bowel obstruction and two as a small bowel perforation. None of the cases had a preoperative diagnosis of endometriosis. The interest of these cases lies in this exceptional form of presentation, such as a surgical acute abdomen. Therefore, intestinal endometriosis should be taken into account in the differential diagnosis of an acute obstructive or perforative process of the small or large bowel. PMID:27629952

Hence, it is important to develop an autonomous robotic system to perform remote ultrasound scans. Previously, we developed a robotic system for automatic ultrasound scan focusing on human's liver. In order to make it a completely autonomous system, we present in this paper a way to autonomously localize the epigastric region as the starting position for the automatic ultrasound scan. An image processing algorithm marks the umbilicus and mammary papillae on a digital photograph of the patient's abdomen. Then, we made estimation for the location of the epigastric region using the distances between these landmarks. A supporting algorithm distinguishes rib position from epigastrium using the relationship between force and displacement. We implemented these algorithms with the automatic scanning system into an apparatus: a Mitsubishi Electric's MELFA RV-1 six axis manipulator. Tests on 14 healthy male subjects showed the apparatus located the epigastric region with a success rate of 94%. The results suggest that image recognition was effective in localizing a human body part. PMID:24110822

    Recent innovations in computed tomographic (CT) hardware and software have allowed implementation of low tube voltage imaging into everyday CT scanning protocols in adults. CT at a low tube voltage setting has many benefits, including (a) radiation dose reduction, which is crucial in young patients and those with chronic medical conditions undergoing serial CT examinations for disease management; and (b) higher contrast enhancement. For the latter, increased attenuation of iodinated contrast material improves the evaluation of hypervascular lesions, vascular structures, intestinal mucosa in patients with bowel disease, and CT urographic images. Additionally, the higher contrast enhancement may provide diagnostic images in patients with renal dysfunction receiving a reduced contrast material load and in patients with suboptimal peripheral intravenous access who require a lower contrast material injection rate. One limitation is that noisier images affect image quality at a low tube voltage setting. The development of denoising algorithms such as iterative reconstruction has made it possible to perform CT at a low tube voltage setting without compromising diagnostic confidence. Other potential pitfalls of low tube voltage CT include (a) photon starvation artifact in larger patients, (b) accentuation of streak artifacts, and (c) alteration of the CT attenuation value, which may affect evaluation of lesions on the basis of conventional enhancement thresholds. CT of the abdomen with a low tube voltage setting is an excellent radiation reduction technique when properly applied to imaging of select patients in the appropriate clinical setting. PMID:26473536

  8. miR-965 controls cell proliferation and migration during tissue morphogenesis in the Drosophila abdomen

    Formation of the Drosophila adult abdomen involves a process of tissue replacement in which larval epidermal cells are replaced by adult cells. The progenitors of the adult epidermis are specified during embryogenesis and, unlike the imaginal discs that make up the thoracic and head segments, they remain quiescent during larval development. During pupal development, the abdominal histoblast cells proliferate and migrate to replace the larval epidermis. Here, we provide evidence that the microRNA, miR-965, acts via string and wingless to control histoblast proliferation and migration. Ecdysone signaling downregulates miR-965 at the onset of pupariation, linking activation of the histoblast nests to the hormonal control of metamorphosis. Replacement of the larval epidermis by adult epidermal progenitors involves regulation of both cell-intrinsic events and cell communication. By regulating both cell proliferation and cell migration, miR-965 contributes to the robustness of this morphogenetic system. DOI: http://dx.doi.org/10.7554/eLife.07389.001 PMID:26226636

    Transmesocolic hernia is an uncommon type of internal hernia with incidence ranging from approximately 5-10%. To the best of our knowledge, this is the first reported case of a transmesocolic hernia through a gap within the descending mesocolon presenting clinically as an intestinal obstruction. A 75-year-old man was admitted with clinical features of intestinal obstruction. An abdominal X-ray showed multiple small bowel loops with air fluid levels. Contrast-enhanced CT of the abdomen revealed small bowel obstruction not only on the right, but also on the left side of the collapsed descending colon. Emergency surgery was performed. Strangulated bowel loops with gangrenous changes were resected and double-barrel ileostomy was carried out. The postoperative period was uneventful. Restoration of bowel was performed after 6 weeks. Preoperative diagnosis of bowel obstruction caused by a transmesocolic hernia remains difficult despite the currently available imaging techniques. Prompt surgery can prevent serious complications such as peritonitis and sepsis.

    Non-permanent, non-woven options for the closure of an open abdomen have previously been limited to biologics such as Permacol or Strattice. Gore Bio-A is constructed from biocompatible synthetic fibres, the use of which has only been described in the repair of inguinal hernia, hiatal hernia and fistula-in-ano. A 60-year-old male underwent emergency laparotomy, partial gastrectomy and formation of a feeding jejunostomy for a strangulated and perforated intrathoracic hiatus hernia. His abdominal wall subsequently dehisced for which he underwent laparostomy and subsequent early closure with a Gore Bio-A mesh, secured in an onlay manner with 2/0 vicryl. Functional and cosmetic outcomes were satisfactory and the patient was discharged home. The use of Gore Bio-A is a safe, feasible and cost effective alternative to traditional biologics for the closure of a laparostomy, deployment of which is safe within a contaminated field. Further prospective data is needed to clarify its role.

    Hypocholesterolemia is characterized by serum total cholesterol that is lower than the 5th percentile for age and sex, or the cut-off value which predicts the adverse prognosis by epidemiological study. Unlike hypercholesterolemia, physicians pay less attention to the morbidity, causes and consequences of hypocholesterolemia in clinical practice. In fact, hypocholesterolemia is a common dislipidemia, and mainly results from secondary factors. The causes of primary hypocholesterolemia are some disorders owing to genetic mutation in the pathway of cholesterol absorption, biosynthesis or metabolism, including abetalipoproteinemia, hypobetalipoproteinemia, Tangier disease, chylomicron retention disease and inherited disorders of cholesterol biosynthesis. The causes of secondary hypocholesterolemia comprise anemia, hyperthyroidism, malignancy, live disease, critical illness, serious stress, malabsorption or malnutrition, acute or chronic infection, chronic inflammation, and use of some drugs. In addition, what's more important is that hypocholesterolemia can result in some adverse events, such as increased mortality, intracerebral hemorrhage, cancer, infection, adrenal failure, suicide and mental disorder. Therefore, with the practice of intensive lipid-lowering treatment and the tendency to the increased indications of statins, it's high time that physicians attached more importance to hypocholesterolemia.

  2. Patterns of peritoneal spread of tumor in the abdomen and pelvis.

    PubMed

    Le, Ott

    2013-03-28

    The spread of tumor in the peritoneum can be understood, although it is a complex organ. A study of its embryology, anatomy and function is of clear benefit. It is formed from a network of folds, reflections, and potential spaces produced by the visceral and parietal peritoneum. These folds and reflections begin as a dorsal and ventral mesentery, supporting the primitive gut in early embryologic development. The dorsal mesentery connects the stomach and other organs to the posterior abdominal wall, while the ventral mesentery connects the stomach to the ventral abdominal wall. As the embryo develops, there is further organ growth, elongation, cavitation and rotation. The dorsal and ventral mesentery also develops along with the viscera, forming ligaments, mesenteries, omenta and potential spaces from the resulting reflections and folds. These ligaments, mesenteries, and omenta, support and nurture the organs of the peritoneum, providing a highway for arteries, veins, nerves and lymphatics. The potential spaces created from these folds and reflections of the visceral and parietal peritoneum are also important to realize. For example, the transverse mesocolon divides the peritoneal cavity into a supramesocolic and inframesocolic space in the abdomen and paravesicular spaces within the pelvis. The falciform ligament is well known in the supramesocolic space, dividing it further into a left and right compartment. Knowledge of the peritoneal vascular anatomy is beneficial in locating the spaces and ligaments about the peritoneum. For example, identifying the left gastric artery or vein will lead to the gastrohepatic ligament, which is part of the supramesocolic space. Besides serving a life sustaining role, the multiple compartments, ligaments, mesenteries and omenta within the peritoneum can also facilitate the spread of disease. Tumors can spread directly from one organ to another, seed metastatic deposits in the peritoneal cavity, and travel through the lymphatic or

    To determine the influence of body position on chest wall and pulmonary function, we studied the ventilatory, pulmonary mechanics, and thoracoabdominal motion profiles in 20 preterm infants recovering from respiratory disease who were positioned in both the supine and prone position. Thoracoabdominal motion was assessed from measurements of relative rib cage and abdominal movement and the calculated phase angle (an index of thoracoabdominal synchrony) of the rib and abdomen Lissajous figures. The ventilatory and pulmonary function profiles were assessed from simultaneous measurements of transpulmonary pressure, airflow, and tidal volume. The infants were studied in quiet sleep, and the order of positioning was randomized across patients. The results demonstrated no significant difference in ventilatory and pulmonary function measurements as a function of position. In contrast, there was a significant reduction (-49%) in the phase angle of the Lissajous figures and an increase (+66%) in rib cage motion in prone compared with the supine position. In addition, the degree of improvement in phase angle in the prone position was correlated to the severity of asynchrony in the supine position. We speculate that the improvement in thoracoabdominal synchrony in the prone position is related to alterations of chest wall mechanics and respiratory muscle tone mediated by a posturally related shift in the area of apposition of the diaphragm to the anterior inner rib cage wall and increase in passive tension of the muscles of the rib cage. This study suggests that the mechanical advantage associated with prone positioning may confer a useful alternative breathing pattern to the preterm infant in whom elevated respiratory work loads and respiratory musculoskeletal immaturity may predispose to respiratory failure.

    Members of many species tend to congregate, a behavioral strategy known as local enhancement. Selective advantages of local enhancement range from efficient use of resources to defense from predators. While previous studies have examined many types of social behavior in fruit flies, few have specifically investigated local enhancement. Resource-independent local enhancement has recently been described in the fruit fly using a measure called social space index, although the neural mechanisms remain unknown. Here we analyze resource-independent local enhancement of Drosophila under conditions that allow us to elucidate its neural mechanisms. We have investigated the effects of general volatile anesthetics, compounds that compromise higher order functioning of the type typically required for responding to social cues. We exposed Canton-S flies to non-immobilizing concentrations of halothane and found that flies had a significantly decreased social space index compared to flies tested in air. Narrow abdomen (na) mutants, which display altered responses to anesthetics in numerous behavioral assays, also have a significantly reduced social space index, an effect that was fully reversed by restoring expression of na by driving a UAS-NA rescue construct with NA-GAL4. We found that na expression in cholinergic neurons fully rescued the behavioral defect, whereas expression of na in glutamatergic neurons did so only partially. Our results also suggest a role for na expression in the mushroom bodies, since suppressing na expression in the mushroom bodies of NA-GAL4 rescue flies diminishes social space index. Our data indicate that resource-independent local enhancement, a simple behavioral strategy, requires complex neural processing. PMID:23398613

    In the genus Panorpa (Insecta: Mecoptera), also known as scorpionflies, premating behavior includes repeated sequences of slow wing movements (waving, fanning, flagging) which are accompanied by rapid abdomen vibrations that generate substantial substrate-borne sound. It is still unknown whether wing patterns or vibratory signals contain information about species identity, sex and/or the quality of potential mating partners. Besides species-specific pheromones, these multimodal signals may be of particular importance for the maintenance of reproductive isolation in sympatrically occurring scorpionfly species. Here, we analyzed phyologenetic relationships among, and the pattern of forewings as well as substrate-borne sound in 3 different sympatric Central-European scorpionfly species (P. communis, P. germanica, and P. alpina). Divergence time estimates, based on 879 bp of the mitochondrial COI gene, indicate longstanding separate evolutionary histories for the studied Panorpa species. Morphological analysis revealed that wing length as an indicator of body size increased in the following order: P. alpina < P. germanica < P. communis. Individuals can be assigned to the correct species and sex with high accuracy just by evaluation of the number of dark spots and the proportion of wing pigmentation. Despite high variability of interpulse period at an individual level, across species analysis revealed a positive correlation of average interpulse period as well as mean signal amplitude with forewing length. These results suggest wing patterns, but less likely vibratory signals, to contain information about species identity. Furthermore, receivers may be able to estimate the body size of a signaler solely on the basis of substrate-borne sound. PMID:24818592

    Cytokines have been shown to play a pivotal role in multiple organ dysfunction, a major cause of death in severe acute pancreatitis. Moreover, the two-hit hypothesis of the cytokine-induced systemic inflammatory response syndrome explains the variable individual response to severe acute pancreatitis and the impact of secondary events such as sepsis or therapeutic intervention. Many experimental anti-cytokine therapies have been administered following induction of experimental pancreatitis, and have proved to be therapeutic. Patients with severe pancreatitis present early because of pain. Clearly then a window for therapeutic intervention is available between onset of symptoms and peak pro-inflammatory cytokine expression. It is this fundamental observation that convinces many in the field that the treatment of AP will be one of the first clinical successes for novel drugs or therapy that seek to modulate the inflammatory response.

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

    The efficacy of high intensity focused ultrasound (HIFU) for the non-invasive treatment of cancer has been demonstrated for a range of different cancers including those of the liver, kidney, prostate and breast. As a non-invasive focused therapy, HIFU offers considerable advantages over other techniques such as chemotherapy and surgical resection, in terms of its non-invasiveness and low risk of harmful side effects. There is, however, a number of significant challenges which currently hinder its widespread clinical application. One of these challenges is the need to transmit sufficient energy through the ribcage to induce tissue necrosis at the required foci whilst minimising the formation of side lobes and sparing healthy tissue. Ribs both absorb and reflect ultrasound strongly. As such, a common side effect of focusing ultrasound in regions located behind the rib cage is the overheating of bone and surrounding tissue, which can lead to skin burns. Successful treatment of a patient with tumours in the upper abdomen therefore requires a thorough understanding of the way acoustic and thermal energy are deposited. This is likely to rely on a treatment planning procedure in which optimal source velocity distributions are obtained so as to maximise a dose quantity at the treatment sites, whilst ensuring that this quantity does not exceed a specified threshold at other field locations, particularly on the surface of the ribs. Previously, a boundary element approach based on a Generalised Minimal Residual (GMRES) implementation of the Burton-Miller formulation was developed to predict the field of a multi-element HIFU array scattered by human ribs, the topology of which was obtained from CT scan data [1]. This work describes the reformulation of the boundary element equations as a least-squares minimisation problem with non-linear constraints. The methodology was subsequently tested at an excitation frequency of 100 kHz on a spherical multi-element array in the presence

    Up to the present, the optimal time to close an open abdomen remains controversial. This study was designed to evaluate whether early fascial abdominal closure had advantages over delayed approach for open abdomen populations. Medline, Embase, and Cochrane Library were searched until April 2013. Search terms included “open abdomen,” “abdominal compartment syndrome,” “laparostomy,” “celiotomy,” “abdominal closure,” “primary,” “delayed,” “permanent,” “fascial closure,” and “definitive closure.” Open abdomen was defined as “fail to close abdominal fascia after a laparotomy.” Mortality, complications, and length of stay were compared between early and delayed fascial closure. In total, 3125 patients were included for final analysis, and 1942 (62%) patients successfully achieved early fascial closure. Vacuum assisted fascial closure had no impact on pooled fascial closure rate. Compared with delayed abdominal closure, early fascial closure significantly reduced mortality (12.3% versus 24.8%, RR, 0.53, P < 0.0001) and complication incidence (RR, 0.68, P < 0.0001). The mean interval from open abdomen to definitive closure ranged from 2.2 to 14.6 days in early fascial closure groups, but from 32.5 to 300 days in delayed closure groups. This study confirmed clinical advantages of early fascial closure over delayed approach in treatment of patients with open abdomen. PMID:24987411

    Atraumatic splenic rupture is an uncommon complication of acute pancreatitis. This report describes the case of a 30-year-old man with acute pancreatitis and splenic vein thrombosis complicated by splenic rupture. The patient was admitted to the emergency department with pain in the upper abdomen that had been present for six hours and was associated with vomiting and sweating. He was diagnosed with acute pancreatitis of alcoholic etiology. Upon computed tomography (CT) of the abdomen, the pancreatitis was scored as Balthazar C grade, and a suspicious area of necrosis affecting 30% of the pancreas with splenic vein thrombosis was revealed. Seventy-two hours after admission, the patient had significant improvement in symptoms. However, he showed clinical worsening on the sixth day of hospitalization, with increasing abdominal distension and reduced hemoglobin levels. A CT angiography showed a large amount of free fluid in the abdominal cavity, along with a large splenic hematoma and contrast extravasation along the spleen artery. The patient subsequently underwent laparotomy, which showed hemoperitoneum due to rupture of the splenic parenchyma. A splenectomy was then performed, followed by ultrasound-guided percutaneous drainage.

    Acute gastroenteritis is a common infectious disease syndrome, causing a combination of nausea, vomiting, diarrhea, and abdominal pain. There are more than 350 million cases of acute gastroenteritis in the United States annually and 48 million of these cases are caused by foodborne bacteria. Traveler's diarrhea affects more than half of people traveling from developed countries to developing countries. In adult and pediatric patients, the prevalence of Clostridium difficile is increasing. Contact precautions, public health education, and prudent use of antibiotics are necessary goals in decreasing the prevalence of Clostridium difficle. Preventing dehydration or providing appropriate rehydration is the primary supportive treatment of acute gastroenteritis.

    Patient: Female, 66 Final Diagnosis: Calciphylaxis Symptoms: Gastrointesinal haemorrhage Medication: None Clinical Procedure: Hemodialysis • blood transfusions Specialty: Gastroenterology and Hepatology Objective: Rare disease Background: Calciphylaxis is associated with a high mortality that approaches 80%. The diagnosis is usually made when obvious skin lesions (painful violaceous mottling of the skin) are present. However, visceral involvement is rare. We present a case of calciphylaxis leading to lower gastrointestinal (GI) bleeding and rectal ulceration of the GI mucosa. Case Report: A 66-year-old woman with past medical history of diabetes mellitus, hypertension, end-stage renal disease (ESRD), recently diagnosed ovarian cancer, and on hemodialysis (HD) presented with painful black necrotic eschar on both legs. The radiograph of the legs demonstrated extensive calcification of the lower extremity arteries. The hospital course was complicated with lower GI bleeding. A CT scan of the abdomen revealed severe circumferential calcification of the abdominal aorta, celiac artery, and superior and inferior mesenteric arteries and their branches. Colonoscopy revealed severe rectal necrosis. She was deemed to be a poor surgical candidate due to comorbidities and presence of extensive vascular calcifications. Recurrent episodes of profuse GI bleeding were managed conservatively with blood transfusion as needed. Following her diagnosis of calciphylaxis, supplementation with vitamin D and calcium containing phosphate binders was stopped. She was started on daily hemodialysis with low calcium dialysate bath as well as intravenous sodium thiosulphate. The clinical condition of the patient deteriorated. The patient died secondary to multiorgan failure. Conclusions: Calciphylaxis leading to intestinal ischemia/perforation should be considered in the differential diagnosis in ESRD on HD presenting with abdominal pain or GI bleeding. PMID:26572938

    Encapsulated collections of bile (“biloma”) may be a sequela of liver trauma, operative injury or disease. Such collections may be intrahepatic or extrahepatic and usually in the supramesocolic compartment of the abdomen. This is a report of a retroperitoneal biloma, an entity that has been reported only twice to date but this is the first secondary to an operative common bile duct lesion. Evacuation of the biloma and reconstruction of the associated biliary stricture were successfully carried out. The patient remains sympton free with normal clinical and laboratory data more than 14 months after surgery. Operative common bile duct (CBD) injury may be followed by a number of complications. To our knowledge retroperitoneal biloma secondary to a CBD lesion has not been previously reported. PMID:2043516

    Primary immune thrombocytopenic purpura (ITP) remains a diagnosis of exclusion both from nonimmune causes of thrombocytopenia and immune thrombocytopenia that develops in the context of other disorders (secondary immune thrombocytopenia). The pathobiology, natural history, and response to therapy of the diverse causes of secondary ITP differ from each other and from primary ITP, so accurate diagnosis is essential. Immune thrombocytopenia can be secondary to medications or to a concurrent disease, such as an autoimmune condition (eg, systemic lupus erythematosus [SLE], antiphospholipid antibody syndrome [APS], immune thyroid disease, or Evans syndrome), a lymphoproliferative disease (eg, chronic lymphocytic leukemia or large granular T-lymphocyte lymphocytic leukemia), or chronic infection, eg, with Helicobacter pylori, human immunodeficiency virus (HIV), or hepatitis C virus (HCV). Response to infection may generate antibodies that cross-react with platelet antigens (HIV, H pylori) or immune complexes that bind to platelet Fcγ receptors (HCV) and platelet production may be impaired by infection of megakaryocyte bone marrow-dependent progenitor cells (HCV and HIV), decreased production of thrombopoietin (TPO), and splenic sequestration of platelets secondary to portal hypertension (HCV). Sudden and severe onset of thrombocytopenia has been observed in children after vaccination for measles, mumps, and rubella or natural viral infections, including Epstein-Barr virus, cytomegalovirus, and varicella zoster virus. This thrombocytopenia may be caused by cross-reacting antibodies and closely mimics acute ITP of childhood. Proper diagnosis and treatment of the underlying disorder, where necessary, play an important role in patient management. PMID:19245930

    The abdomen is the second most commonly injured region in children using adult seat belts, but engineers are limited in their efforts to design systems that mitigate these injuries since no current pediatric dummy has the capability to quantify injury risk from loading to the abdomen. This paper develops a porcine (sus scrofa domestica) model of the 6-year-old human's abdomen, and then defines the biomechanical response of this abdominal model. First, a detailed abdominal necropsy study was undertaken, which involved collecting a series of anthropometric measurements and organ masses on 25 swine, ranging in age from 14 to 429 days (4-101 kg mass). These were then compared to the corresponding human quantities to identify the best porcine representation of a 6-year-old human's abdomen. This was determined to be a pig of age 77 days, and whole-body mass of 21.4 kg. The sub-injury, quasistatic response to belt loading of this porcine model compared well with pediatric human volunteer tests performed with a lap belt on the lower abdomen. A test fixture was designed to produce transverse, dynamic belt loading on the porcine abdomen. A detailed review of field cases identified the following test variables: loading location (upper/lower), penetration magnitude (23%-68% of initial abdominal depth), muscle tensing (yes/no), and belt penetration rate (quasistatic, dynamic 2.9 m/s - 7.8 m/s). Dynamic tests were performed on 47 post-mortem subjects. Belt tension and dorsal reaction force were cross-plotted with abdominal penetration to generate structural response corridors. Subcutaneous stimulation of the anterior abdominal muscle wall stiffened the quasistatic response significantly, but was of negligible importance in the dynamic tests. The upper abdomen exhibited stiffer response quasistatically, and also was more sensitive to penetration rate, with stiffness increasing significantly over the range of dynamic rates tested here. In contrast, the lower abdomen was relatively

    The use of three physical image quality metrics, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and mean effective noise equivalent quanta (eNEQm) have recently been examined by our group for their appropriateness in the calibration of an automatic exposure control (AEC) device for chest radiography with an Agfa computed radiography (CR) imaging system. This study uses the same methodology but investigates AEC calibration for abdomen, pelvis and spine CR imaging. AEC calibration curves were derived using a simple uniform phantom (equivalent to 20 cm water) to ensure each metric was held constant across the tube voltage range. Each curve was assessed for its clinical appropriateness by generating computer simulated abdomen, pelvis and spine images (created from real patient CT datasets) with appropriate detector air kermas for each tube voltage, and grading these against reference images which were reconstructed at detector air kermas correct for the constant detector dose indicator (DDI) curve currently programmed into the AEC device. All simulated images contained clinically realistic projected anatomy and were scored by experienced image evaluators. Constant DDI and CNR curves did not provide optimized performance but constant eNEQm and SNR did, with the latter being the preferred calibration metric given that it is easier to measure in practice. This result was consistent with the previous investigation for chest imaging with AEC devices. Medical physicists may therefore use a simple and easily accessible uniform water equivalent phantom to measure the SNR image quality metric described here when calibrating AEC devices for abdomen, pelvis and spine imaging with Agfa CR systems, in the confidence that clinical image quality will be sufficient for the required clinical task. However, to ensure appropriate levels of detector air kerma the advice of expert image evaluators must be sought.

    Thoracic duct cysts, which may be of congenital or degenerative origin, are very rare lesions. Most patients are asymptomatic, but when symptoms are present they include cough, dyspnea, dysphagia and chest pain. However, in this case report a 35-year-old male patient presented to us with intermittent abdomen pain. Clinical symptoms and radiographic findings helped to identify a giant thoracic duct cyst in this patient. Surgical resection of the cyst resolved the abdominal symptoms. This was the first case reported in the literature of a thoracic duct cyst with the symptoms of abdominal pain. PMID:26004105

    Pazopanib is an oral angiogenesis inhibitor targeting vascular endothelial growth factor receptors, platelet-derived growth factor receptors, and c-Kit approved for the treatment of renal cell carcinoma and soft tissue sarcoma. Nonselective kinase inhibitors, such as sunitinib and sorafenib, are known to be associated with acute pancreatitis. There are few case reports of severe acute pancreatitis induced by pazopanib treatment. We present a case of severe acute pancreatitis caused by pazopanib treatment for cutaneous angiosarcoma. The patient was an 82-year-old female diagnosed with cutaneous angiosarcoma. She had been refractory to docetaxel treatment and began pazopanib therapy. Three months after pazopanib treatment, CT imaging of the abdomen showed the swelling of the pancreas and surrounding soft tissue inflammation without abdominal pain. After she continued pazopanib treatment for 2 months, she presented with nausea and appetite loss. Abdominal CT showed the worsening of the surrounding soft tissue inflammation of the pancreas. Serum amylase and lipase levels were 296 and 177 IU/l, respectively. She was diagnosed with acute pancreatitis induced by pazopanib treatment and was managed conservatively with discontinuation of pazopanib, but the symptoms did not improve. Subsequently, an abdominal CT scan demonstrated the appearance of a pancreatic pseudocyst. She underwent endoscopic ultrasound-guided pseudocyst drainage using a flared-end fully covered self-expandable metallic stent. Then, the symptoms resolved without recurrence. Due to the remarkable progress of molecular targeted therapy, the oncologist should know that acute pancreatitis was recognized as a potential adverse event of pazopanib treatment and could proceed to severe acute pancreatitis.

    Purpose: To present a study of radiation dose measurements with a human cadaver scanned on a clinical CT scanner. Methods: Multiple point dose measurements were obtained with high-accuracy Thimble ionization chambers placed inside the stomach, liver, paravertebral gutter, ascending colon, left kidney, and urinary bladder of a human cadaver (183 cm in height and 67.5 kg in weight) whose abdomen/pelvis region was scanned repeatedly with a multidetector row CT. The flat energy response and precision of the dosimeters were verified, and the slight differences in each dosimeter's response were evaluated and corrected to attain high accuracy. In addition, skin doses were measured for radiosensitive organs outside the scanned region with OSL dosimeters: the right eye, thyroid, both nipples, and the right testicle. Three scan protocols were used, which shared most scan parameters but had different kVp and mA settings: 120-kVp automA, 120-kVp 300 mA, and 100-kVp 300 mA. For each protocol three repeated scans were performed. Results: The tube starting angle (TSA) was found to randomly vary around two major conditions, which caused large fluctuations in the repeated point dose measurements: for the 120-kVp 300 mA protocol this angle changed from approximately 110° to 290°, and caused 8% − 25% difference in the point dose measured at the stomach, liver, colon, and urinary bladder. When the fluctuations of the TSA were small (within 5°), the maximum coefficient of variance was approximately 3.3%. The soft tissue absorbed doses averaged from four locations near the center of the scanned region were 27.2 ± 3.3 and 16.5 ± 2.7 mGy for the 120 and 100-kVp fixed-mA scans, respectively. These values were consistent with the corresponding size specific dose estimates within 4%. The comparison of the per-100-mAs tissue doses from the three protocols revealed that: (1) dose levels at nonsuperficial locations in the TCM scans could not be accurately deduced by simply scaling the

Here we present an extremely rare case of PCCof the appendix in a 32-year-old male who presented with acute pain abdomen. Histopathological examination revealed PCC of the appendix. Examination of the testis was unremarkable. Further investigations revealed a very high serum beta-human chorionic gonadotropin (b-HCG) titer with a normal carcinoembryonic antigen (CEA). Radiological imaging showed multiple areas of liver metastasis. Chemotherapy-based treatment with bleomycin, etoposide, and cisplatin (BEP) regime was advised, however the patient failed to follow-up for further management. PMID:26881617

    We used a vascular access system (VAS) for continuous arterial infusion (CAI) of a protease inhibitor in two patients with acute necrotizing pancreatitis. The infusion catheter was placed into the dorsal pancreatic artery in the first patient and into the gastroduodenal artery in the second, via a femoral artery approach. An implantable port was then connected to the catheter and was secured in a subcutaneous pocket prepared in the right lower abdomen. No complications related to the VAS were encountered. This system provided safe and uncontaminated vascular access for successful CAI for acute pancreatitis.

    Accidental genital trauma is most commonly caused by straddle-type injuries and is usually treatable by nonoperative management, and most of the injuries have a good prognosis. When the bleeding occurred due to straddle injury in adolescent girl, experienced gynecological examination and treatment were very important. We experienced a case of straddle injury to the posterior fourchette that caused acute hematocolpos due to delayed adequate treatment with hypotension and acute abdomen in an adolescent girl. This case shows the importance of careful and accurate physical and gynecological examination and adequate and prompt treatment of genital trauma in adolescent girls.

    In 21 healthy volunteers the ratio of amylase clearance and creatinine clearance (Cam/Ccr) was determined in urine collected at admission, after a 1-hour collection period and after a 2-hour collection period. The normal values were 1.8 +/- 1.6%, 1.9 +/- 2% and 2.0 +/- 1.7% respectively. They were comparable with those published by others. The reproducibility of the method was acceptable (r = 0.62). When compared with serum amylase determinations, Cam/Ccr showed neither better sensitivity in 19 patients suffering an acute episode of proven pancreatitis, nor better specificity in 19 patients with acute abdomen but no evidence of pancreatitis.

    We report a case of heparin-induced thrombocytopenia in a patient on low molecular weight heparin bridge therapy who developed acute abdominal aortic stent-graft thrombosis 1 week after uncomplicated endovascular abdominal aortic aneurysm repair. The diagnosis was confirmed by a computed tomographic scan of the abdomen. The patient was successfully treated by conversion to open repair. The postoperative course was marked by subacute left limb ischemia related to an in vivo cross-reactivity of danaparoid with the heparin immune complex. To our knowledge, this is the first case report of heparin-induced thrombocytopenia with acute abdominal aortic stent-graft thrombosis. PMID:23711968

    We describe a rare case of a patient with colonic diverticular perforation manifested only by subcutaneous emphysema of the neck, chest, and abdomen, as visualized by a computed tomography (CT) scan. The 76-year-old female patient with a history of internal diseases was urgently admitted to the Clinic of Internal Diseases due to a urinary tract infection. During the hospitalization, further diagnostic procedures were performed due to palpable subcutaneous emphysema of the neck, chest, and abdomen. Computed tomography examination revealed massive intra-abdominal, intramuscular, and subcutaneous emphysema. A decision was made to perform exploratory laparotomy; the procedure exposed an inveterate diverticular perforation of the sigmoid-rectal flexure as well as air-inflated retroperitoneal tissue. The perforated colon was resected, and a stoma was formed. On the 15th postoperative day, the patient died due to cardiorespiratory failure. Although subcutaneous emphysema is a common symptom in everyday medical practice, its etiology remains complex. One should consider this clinical presentation of colonic diverticular perforation, especially in elderly patients in whom the perforation signs may be clinically less marked. PMID:27212982

    Purpose To evaluate image quality and radiation dose of routine abdomen computed tomography exam with the automatic current modulation technique (ATCM) performed in two different brand 64-slice CT scanners in our site. Materials and Methods A retrospective review of routine abdomen CT exam performed with two scanners; scanner A and scanner B in our site. To calculate standard deviation of the portal hepatic level with a region of interest of 12.5 mm x 12.5mm represented to the image noise. The radiation dose was obtained from CT DICOM image information. Using Computed tomography dose index volume (CTDIv) to represented CT radiation dose. The patient data in this study were with normal weight (about 65–75 Kg). Results The standard deviation of Scanner A was smaller than scanner B, the scanner A might with better image quality than scanner B. On the other hand, the radiation dose of scanner A was higher than scanner B(about higher 50–60%) with ATCM. Both of them, the radiation dose was under diagnostic reference level. Conclusion The ATCM systems in modern CT scanners can contribute a significant reduction in radiation dose to the patient. But the reduction by ATCM systems from different CT scanner manufacturers has slightly variation. Whatever CT scanner we use, it is necessary to find the acceptable threshold of image quality with the minimum possible radiation exposure to the patient in agreement with the ALARA principle.

    Patient: Male, 53 Final Diagnosis: Leptospirosis Symptoms: — Medication: — Clinical Procedure: None Specialty: Infectious Diseases Objective: Rare disease Background: Unexplained renal insufficiency combined with hepatic failure is a common problem encountered by clinicians. As with many disease processes involving multi-organ systems, reversible causes are usually not readily identifiable, and for many patients their health deteriorates rapidly. We present a rare cause of acute renal failure and hyperbilirubinemia occurring simultaneously, with leptospirosis presenting as Weil’s disease. Case Report: A 53-year-old male presented to our clinic with complaints of anuria over the past two days. His symptoms started with dark urine, severe cramps in the thighs, and chills. The patient was a visitor to the United States from Guyana. Positive physical examination findings included mild tachycardia and hypotension, scleral icterus, and tenderness over abdomen, costovertebral angles, and thighs. The patient had a high white blood cell count, thrombocytopenia, renal/hepatic insufficiency, and an urinary tract infection (UTI). The patient was initially treated under the suspicion of acute kidney injury secondary to rhabdomyolysis and pyelonephritis. The patient continued to deteriorate with decreasing platelet counts, worsening renal function, hyperbilirubinemia, and respiratory distress, with no improvement with hemodialysis. Broad-spectrum antibiotics were administered, including doxycycline, due to a high suspicion of leptospirosis. The patient’s condition drastically improved after initiation of doxycycline. On subsequent days, the patient’s Leptospira antibody results were available, showing titers of more than 1:3200. Hemodialysis was discontinued as the patient started producing urine with improved kidney function. Conclusions: As world travel becomes more economically feasible, we will continue to encounter foreign endemic diseases. Leptospirosis

    The so-called stunned myocardium, defined as transitory myocardial contractile dysfunction, has been clearly demonstrated in diverse clinical situations. However, stunned myocardium related to ischemic stroke has been poorly identified. We describe two patients with diagnosis of acute ischemic stroke who developed eletrocardiographic changes, cardiac enzyme increasing levels and myocardial dysfunction secondary to abnormal cardiac wall motion. At the same time the patients developed acute lung injury with rapid resolution, perhaps as a consequence of neurocardiogenic components.

    Acute hypertension (HTN) in hospitalized children and adolescents occurs relatively frequently and in some cases, if not recognized and treated promptly, it can lead to hypertensive crisis with potentially significant morbidity and mortality. In contrast to adults, where acute HTN is most likely due to uncontrolled primary HTN, children and adolescents with acute HTN are more likely to have secondary HTN. This review will briefly cover evaluation of acute HTN and various age specific etiologies of secondary HTN and provide more in-depth discussion on treatment target, potential risks of acute HTN therapy, available pediatric data on intravenous and oral antihypertensive agents, and propose treatment schema including unique therapy of specific secondary HTN scenarios.

    The sensitivity and specificity of amylasemia, the ratios of amylase/creatinine clearance and amylasuria/creatininuria were determined in four groups of patients: a control group (n = 43), patients with acute pancreatitis detected on computed tomography (n = 30, 25 cases of alcoholic pancreatitis), patients with an acute surgical abdomen without pancreatitis (n = 25), and patients with renal failure (n = 20). Sensitivity was defined for the acute pancreatitis group and specificity for the other groups. When amylasemia was greater than 20 UI/dl and the amylasuria/creatininuria ratio greater than 100, sensitivity was 98 per cent. The specificity of these two results in patients with an acute surgical abdomen was 98 per cent. When the ratio amylase/creatinine clearance ratio was greater than 4 sensitivity was 73 per cent and specificity in patients with acute surgical abdomen was 75 per cent. These two values were lower than those of the two preceding tests (p less than 0.01). Sensitivity of the association of an amylasemia greater than 13 UI/dl (m + 2SD) with a clearance ratio greater than 4 was 73 per cent. The amylase/creatinine clearance ratio did not seem to be reliable since its change was delayed with respect to the increase of amylasemia and amylasuria. This ratio has a poor specificity as it increased when the clearance of creatinine decreased in the group with an acute surgical abdomen associated with functional or organic renal failure. In these two groups, the correlation between the amylase/creatinine clearance ratio and creatininemia was significant. This suggested that the clearance of creatinine fell more rapidly than the clearance of amylase as renal failure increased.

    Acute rhinosinusitis is a common disease with worldwide prevalence. It is a significant burden on the health services. It is most commonly caused by viruses and is self‐limiting in nature. The diagnosis of acute rhinosinusitis is clinical and sinus radiography is not indicated routinely. Most cases of acute rhinosinusitis are treated symptomatically. However, symptoms may persist beyond 10 days when secondary bacterial infection prevails. Antibiotics are reserved for moderate or severe cases or when there is development of complications of acute rhinosinusitis. This paper provides an update on the current management of acute rhinosinusitis. PMID:17551072

    For many decades two types of acute pancreatitis have been recognized: the edematous or interstitial and the hemorrhagic or necrotic. In most cases acute pancreatitis is associated with alcoholism or biliary tract disease. Elevated serum or urinary α-amylase is the most important finding in diagnosis. The presence of methemalbumin in serum and in peritoneal or pleural fluid supports the diagnosis of the hemorrhagic form of the disease in patients with a history and enzyme studies suggestive of pancreatitis. There is no characteristic clinical picture in acute pancreatitis, and its complications are legion. Pancreatic pseudocyst is probably the most common and pancreatic abscess is the most serious complication. The pathogenetic principle is autodigestion, but the precise sequence of biochemical events is unclear, especially the mode of trypsinogen activation and the role of lysosomal hydrolases. A host of metabolic derangements have been identified in acute pancreatitis, involving lipid, glucose, calcium and magnesium metabolism and changes of the blood clotting mechanism, to name but a few. Medical treatment includes intestinal decompression, analgesics, correction of hypovolemia and other supportive and protective measures. Surgical exploration is advisable in selected cases, when the diagnosis is in doubt, and is considered imperative in the presence of certain complications, especially pancreatic abscess.

    Recent advances in radiotherapy techniques have allowed a significant improvement in the therapeutic ratio of whole abdominal irradiation (WAI) through linear-accelerator (Linac) based intensity-modulated radiotherapy (IMRT) and helical tomotherapy (HT). IMRT has been shown to reduce the dose to organs at risk (OAR) while adequately treating the tumor volume. HT operates by adjusting 51 beam directions, couch speed, pitch and shapes of a binary multileaf collimator (MLC), with the purpose of clinically increasing the befit to the patient. We incorporated helical tomotherapy as a new modality for WAI for the treatment of non-Hodgkin's lymphoma patients whose disease involved the intestine and the mesenteric lymph nodes. Excellent tumor coverage with effective sparing of normal organ sparings, and homogeneous dose distribution could be achieved. This study dosimetrically compared HT and linac-based IMRT by using several indices, including the conformity index (CI) and the homogeneity index (HI) for the planning target volume (PTV), as well as the, max dose and the mean dose and the quality index (QI) for five organs at risk (OARs). The HI and the CI were used to compare the quality of target coverage while the QI was used compare the dosimetric performans for OAR systems. The target coverages between the two systems were similar, but the most QIs were lower than 1, what means that HT is batter at sparing OARs than IMRT. Tomotherapy enabled excellent target coverage, effective sparing of normal tissues, and homogeneous dose distribution without severe acute toxicity.

    The article presents a case study of a 37-year-old male who was admitted to the Acute Cardiology Unit of our hospital with suspicion of acute coronary syndrome. By invasive imaging examination, acute coronary syndrome was ruled out, but as a secondary finding a foreign body was found in the pericardium - a broken needle that had travelled to the heart after intravenous heroin administration into the right femoral vein, which was also confirmed on a computed tomography scan. Because of a developing pericardial tamponade, surgical intervention and the extraction of the foreign body was indicated. PMID:24640524

    The existing animal models used for the simulation of acute gastrointestinal bleedings are usually non-survival models. We developed and evaluated a new porcine model (domestic pig, German Landrace) in which the animal remains alive and survives the artificial bleeding without any cardiovascular impairment. This consists of a bleeding catheter which is implanted into the stomach, then subcutaneously tunnelled from the abdomen to the neck where it is exteriorized and fixed with sutures. Using the injection of porcine blood, controllable and reproducible acute upper gastrointestinal bleeding can be simulated while maintaining normal gastrointestinal motility and physiology. Depending on the volume of blood applied through the gastric catheter, the bleeding intensity can be varied from traces of blood to a massive haemorrhage. This porcine model could be valuable, e.g. for testing the efficacy of new bleeding diagnostics in large animals before human use. PMID:26306615

    This is a case report of a 30-year-old man found dead in his flat lying on the floor with multiple stab wounds over the body, surrounded by an extensive volume of blood. Examination of the scene of death showed a secure flat, locked from inside. A blood-stained knife was present close to the body and two unstained notes left on the sofa at the locus. A small plastic bag containing white powder (which following toxicological examinations appeared to be cocaine) and an almost full bottle of beer were present on a table. Autopsy revealed more than 40 stab wounds to neck, chest, and abdomen arranged in isolated groups within which the wounds showed similar directions and had a transverse orientation. Together with hesitation marks located on the neck and wrists these characteristics allowed to interpret this case as a suicide. PMID:20202068

    Chronic aortocaval fistula (ACP) is a rare complication of penetrating trauma to the abdomen. We report a case of traumatic ACP presenting with pulmonary hypertension and right heart failure symptoms 15 years after the initial penetrating injury. Although symptoms of pulmonary hypertension started 5 years ago, it was wrongly diagnosed and treated as chronic obstructive pulmonary disease. The presence of a continuous abdominal bruit and history of penetrating abdominal trauma gave rise to suspicion of a fistula, which was confirmed by computed tomography and angiography. Percutaneous closure of ACP was planned, but the patient died of severe pneumonia. The clinical presentation of chronic ACP can vary from being asymptomatic to symptoms related to pulmonary hypertension, right heart failure, and pulmonary embolism; thus, definitive diagnosis can be challenging.

    The apparent diffusion coefficient (ADC) is an imaging biomarker providing quantitative information on the diffusion of water in biological tissues. This measurement could be of relevance in oncology drug development, but it suffers from a lack of reliability. ADC images are computed by applying a voxelwise exponential fitting to multiple diffusion-weighted MR images (DW-MRIs) acquired with different diffusion gradients. In the abdomen, respiratory motion induces misalignments in the datasets, creating visible artefacts and inducing errors in the ADC maps. We propose a multistep post-acquisition motion compensation pipeline based on 3D non-rigid registrations. It corrects for motion within each image and brings all DW-MRIs to a common image space. The method is evaluated on 10 datasets of free-breathing abdominal DW-MRIs acquired from healthy volunteers. Regions of interest (ROIs) are segmented in the right part of the abdomen and measurements are compared in the three following cases: no image processing, Gaussian blurring of the raw DW-MRIs and registration. Results show that both blurring and registration improve the visual quality of ADC images, but compared to blurring, registration yields visually sharper images. Measurement uncertainty is reduced both by registration and blurring. For homogeneous ROIs, blurring and registration result in similar median ADCs, which are lower than without processing. In a ROI at the interface between liver and kidney, registration and blurring yield different median ADCs, suggesting that uncorrected motion introduces a bias. Our work indicates that averaging procedures on the scanner should be avoided, as they remove the opportunity to perform motion correction.

    Reconstruction of open abdominal defects is a clinical problem which general and plastic surgeons have to address in cooperation. We report the case of a 66-year-old man who presented an abdominal dehiscence after multiple laparotomies for a sigmoid-rectal adenocarcinoma that infiltrated into the abdominal wall, subsequently complicated by peritonitis and enteric fistula. A cutaneous dehiscence and an incontinent abdominal wall resulted after the last surgery. The abdominal wall was reconstructed using a biological porcine cross-linked mesh Permacol (Covidien Inc., Norwalk, CT). Negative Pressure Wound Therapy (NPWT), instead, was used on the mesh in order to reduce wound dimensions, promote granulation tissue formation, and obtain secondary closure of cutaneous dehiscence which was finally achieved with a split-thickness skin graft. Biological mesh behaved like a scaffold for the granulation tissue that was stimulated by the negative pressure. The biological mesh was rapidly integrated in the abdominal wall restoring abdominal wall continence, while the small dehiscence, still present in the central area, was subsequently covered with a split-thickness skin graft. The combination of these different procedures led us to solve this complicated case obtaining complete wound closure after less than 2 months.

    Acute vascular injuries are the second most common cause of fatalities in patients with multiple traumatic injuries; thus, prompt identification and management is essential for patient survival. Over the past few years, multidetector CT (MDCT) using dual-phase scanning protocol has become the imaging modality of choice in high-energy deceleration traumas. The objective of this article was to review the role of dual-phase MDCT in the identification and management of acute vascular injuries, particularly in the chest and abdomen following multiple traumatic injuries. In addition, this article will provide examples of MDCT features of acute vascular injuries with correlative surgical and interventional findings.

    The presentation of acute vertigo may represent both a common benign disorder or a life threatening but rare one. Familiarity with the common peripheral vestibular disorders will allow the clinician to rapidly “rule-in” a benign disorder and recognize when further testing is required. Key features of vertigo required to make an accurate diagnosis are duration, chronicity, associated symptoms, and triggers. Bedside tests that are critical to the diagnosis of acute vertigo include the Dix-Hallpike maneuver and canalith repositioning manuever, occlusive ophthalmoscopy, and the head impulse test. The goal of this review is to provide the clinician with the clinical and pathophysiologic background of the most common disorders that present with vertigo to develop a logical differential diagnosis and management plan.

  13. The effect of secondary inorganic aerosols, soot and the geographical origin of air mass on acute myocardial infarction hospitalisations in Gothenburg, Sweden during 1985–2010: a case-crossover study

    PubMed Central

    2014-01-01

    Background The relative importance of different sources of air pollution for cardiovascular disease is unclear. The aims were to compare the associations between acute myocardial infarction (AMI) hospitalisations in Gothenburg, Sweden and 1) the long-range transported (LRT) particle fraction, 2) the remaining particle fraction, 3) geographical air mass origin, and 4) influence of local dispersion during 1985–2010. Methods A case-crossover design was applied using lag0 (the exposure the same day as hospitalisation), lag1 (exposure one day prior hospitalisation) and 2-day cumulative average exposure (CA2) (mean of lag0 and lag1). The LRT fractions included PMion (sum of sulphate, nitrate and ammonium) and soot measured at a rural site. The difference between urban PM10 (particulate matter with an aerodynamic diameter smaller than 10 μm) and rural PMion was a proxy for locally generated PM10 (PMrest). The daily geographical origin of air mass was estimated as well as days with limited or effective local dispersion. The entire year was considered, as well as warm and cold periods, and different time periods. Results In total 28 215 AMI hospitalisations occurred during 26 years. PM10, PMion, PMrest and soot did not influence AMI for the entire year. In the cold period, the association was somewhat stronger for PMrest than for urban PM10; the strongest associations were observed during 1990–2000 between AMI and CA2 of PMrest (6.6% per inter-quartile range (IQR), 95% confidence interval 2.1 to 11.4%) and PM10 (4.1%, 95% CI 0.2% − 8.2%). Regarding the geographical air mass origins there were few associations. Days with limited local dispersion showed an association with AMI in the cold period of 2001–2010 (6.7%, 95% CI 0.0% − 13.0%). Conclusions In the cold period, locally generated PM and days with limited local dispersion affected AMI hospitalisations, indicating importance of local emissions from e.g. traffic. PMID:25069830

    Diarrhea, defined as three or more loose or watery stools per day, represents a frequent problem in outpatients as well as inpatients. As most of the patients with acute diarrhea show a self-limiting disease course, the main challenge for the physician is to discriminate patients for whom symptomatic therapy is sufficient from those with severe disease course and threatening complications. This review aims to provide a practical guidance for such decisions.

    The author interprets disability on the basis of the "International Classification of Functioning, Disability and Health (ICF)". In this review the applied method is a purpose oriented, restricted survey of continuously increasing articles published during the last two decades. Definition and interpretation of secondary conditions are based on the cited international classification. It is noted that secondary conditions frequently develop during acute care and usually require rehabilitation. Significance of secondary conditions in rehabilitation is highlighted by selected examples of traumatic spinal cord injury, stroke, lower limb amputation and intellectual disabilities. The author states that there is an insufficiency of presently available knowledge and raises the need for the use of the International Classification of Functioning, Disability and Health as foundation of future research.

    Stroke causes a vast amount of death and disability throughout the world, yet for many healthcare professionals it remains an area of therapeutic nihilism, and thus uninteresting. This negative perception is shared by the general public, who often have a poor understanding of the early symptoms and significance of a stroke. Yet within the past few years there have been many important developments in the approach to caring for stroke patients, for both the acute management and secondary prevention. After the completion of numerous clinical trials, there is now robust evidence to either support or discredit various interventions. Even more exciting is the prospect of yet more data becoming available in the near future, testing a whole array of treatments, as clinical interest in stroke expands exponentially. In this review an evidence based approach to the management of acute stroke within the first few days is presented, including ischaemic and haemorrhagic events, but not subarachnoid haemorrhage. It is explained why stroke is regarded as a medical emergency, and the importance of a rational, methodic approach to the initial assessment, which is the key to accurate diagnosis and subsequent management, is emphasised. The potential early problems associated with stroke are identified and specific interventions for different stroke types are discussed. The review ends with a brief discussion of the implications that the evolving treatments have for the organisation of modern stroke services.

    Secondary (specialized) metabolites, produced by bacteria, fungi, plants, and other organisms, exhibit enormous structural variation, and consequently display a wide range of biological activities. Secondary metabolism improves and modulates the phenotype of the host producer. Furthermore, these biological activities have resulted in the use of secondary metabolites in a variety of industrial and pharmaceutical applications. Metabolic engineering presents a powerful strategy to improve access to these valuable molecules. A critical overview of engineering approaches in secondary metabolism is presented, both in heterologous and native hosts. The recognition of the increasing role of compartmentalization in metabolic engineering is highlighted. Engineering approaches to modify the structure of key secondary metabolite classes are also critically evaluated.

    Acute panmyelosis with myelofibrosis (APMF) is an ill-defined disorder that may either evolve as a clonal hematopoietic condition or as a sequel of toxic exposure to the bone marrow (BM). Therefore, controversy and discussion continues as to whether APMF may be considered as a hyperfibrotic (de novo) myelodysplastic syndrome (MDS), as acute myeloid leukemia (AML) or as a severe toxic myelopathy with accompanying myelofibrosis. In this context scant knowledge exists about BM findings, but especially evolution of this disorder according to sequential examinations. Clinically patients present with pancytopenia, a very few blasts in the peripheral blood and no or little splenomegaly. Initially BM histopathology is characterized by different degrees of reticulin-collagen fibrosis and wide ranges of cellularity with a prominent left-shifted and often macrocytic erythropoiesis associated with a reduction and maturation defects of the neutrophil series. Most conspicuous are abnormalities of the megakaryocytes including loose clustering, dislocation towards the endosteal border and appearance of atypical microforms with compact nuclei. Moreover, besides myelofibrosis in a number of patients the interstitial compartment displays a remarkable inflammatory reaction with lymphoid nodules, abundant iron-laden macrophages, perivascular plasmacytosis and increase in microvessels. Repeatedly performed BM biopsies reveal an accumulation of dispersed or clustered CD34+ and lysozyme-expressing blasts in keeping with the insidious transformation into acute leukemia. Prognosis is unfavorable with a median survival of less than 1 year. In conclusion, APMF has to be regarded as a condition that shows considerable overlappings with primary hyperfibrotic MDS, AML and toxic myelopathy (secondary MDS) with accompanying myelofibrosis and therefore can not be considered as a definite clinical entity.

    In aeronautical engineering secondary power systems have long played second fiddle to the airframe, the engine, and indeed, the avionics. This collection of papers is thus timely, and its publication by the Institution of Mechanical Engineers appropriate, as secondary power systems in modern aircraft present challenging mechanical engineering problems. In military aircraft demands for electrical and hydraulic power and high pressure air have grown over the past two decades. To these basic needs are added requirements for emergency power, ground power, and independent engine starting. Additionally increased reliability and maintainability is demanded from all secondary power systems. Complete contents: What is a secondary power system.

    Venereal syphilis is a multi-stage, sexually transmitted disease caused by the spirochetal bacterium Treponema pallidum (Tp). Herein we describe a cohort of 57 patients (age 18–68 years) with secondary syphilis (SS) identified through a network of public sector primary health care providers in Cali, Colombia. To be eligible for participation, study subjects were required to have cutaneous lesions consistent with SS, a reactive Rapid Plasma Reagin test (RPR-titer ≥1∶4), and a confirmatory treponemal test (Fluorescent Treponemal Antibody Absorption test- FTA-ABS). Most subjects enrolled were women (64.9%), predominantly Afro-Colombian (38.6%) or mestizo (56.1%), and all were of low socio-economic status. Three (5.3%) subjects were newly diagnosed with HIV infection at study entry. The duration of signs and symptoms in most patients (53.6%) was less than 30 days; however, some patients reported being symptomatic for several months (range 5–240 days). The typical palmar and plantar exanthem of SS was the most common dermal manifestation (63%), followed by diffuse hypo- or hyperpigmented macules and papules on the trunk, abdomen and extremities. Three patients had patchy alopecia. Whole blood (WB) samples and punch biopsy material from a subset of SS patients were assayed for the presence of Tp DNA polymerase I gene (polA) target by real-time qualitative and quantitative PCR methods. Twelve (46%) of the 26 WB samples studied had quantifiable Tp DNA (ranging between 194.9 and 1954.2 Tp polA copies/ml blood) and seven (64%) were positive when WB DNA was extracted within 24 hours of collection. Tp DNA was also present in 8/12 (66%) skin biopsies available for testing. Strain typing analysis was attempted in all skin and WB samples with detectable Tp DNA. Using arp repeat size analysis and tpr RFLP patterns four different strain types were identified (14d, 16d, 13d and 22a). None of the WB samples had sufficient DNA for typing.

    Rhabdomyolysis is a rare complication that emerges in a variety of infectious diseases, such as tsutsugamushi infection. In this study, we report a 71-year-old female patient with tsutsugamushi infection who exhibiting rhabdomyolysis and acute renal failure. On admission, an eschar, which is characteristic of tsutsugamushi infection, was found on her right flank area. Moreover, her tsutsugamushi antibody titer was 1:40960. The elevated values of serum creatinine phosphokinase (CPK), aldolase, creatinine and dark brown urine secondary to myoglobinuria are consistent with indications of rhabdomyolysis and acute renal failure due to tsutsugamushi infection. Her health improved without any residual effects after treatment with doxycyclin and hydration with normal saline. PMID:14717236

    Primary HIV prevention, preventing HIV exposure among uninfected persons, has been the focus of much attention. However, secondary HIV prevention, preventing HIV transmission from infected people to their uninfected contacts, has not received as much interest or attention from HIV researchers, clinicians, and policymakers. The concept of secondary HIV prevention, as distinguished from primary prevention, is clarified, and the current and future strategies to further secondary HIV prevention efforts are explored. Secondary prevention strategies can be incorporated into comprehensive programs and result in shifts in attitudes and behaviors. This could reduce the size of the epidemic, while also benefiting the individual and his or her close relationships.

    The medical treatment of acute pancreatitis continues to focus on supportive care, including fluid therapy, nutrition, and antibiotics, all of which will be critically reviewed. Pharmacologic agents that were previously studied were found to be ineffective likely due to a combination of their targets and flaws in trial design. Potential future pharmacologic agents, particularly those that target intracellular calcium signaling, as well as considerations for trial design will be discussed. As the incidence of acute pancreatitis continues to increase, greater efforts will be needed to prevent hospitalization, readmission and excessive imaging in order to reduce overall healthcare costs. Primary prevention continues to focus on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis and secondary prevention on cholecystectomy for biliary pancreatitis as well as alcohol and smoking abstinence.

    Speech motor control emerges in the neurophysiologic context of widely distributed, powerful coordinative mechanisms, including those mediating respiratory function. It is unknown, however, whether developing children are able to exploit the capabilities of neural circuits controlling homeostasis for the production of speech and voice. Speech and rest breathing were investigated in eleven 15-month-old children using inductance plethysmography (Respitrace). Rib cage and abdominal kinematics were studied using a time-varying correlational index of thoracoabdominal coupling (i.e., reflecting the synchrony of movement of the rib cage and abdomen) as well as simple classification of the moment-to-moment kinematic relationship of these two functional components (i.e., concurrent expansion or compression, or oppositional movement). Results revealed markedly different patterns of movement for rest breathing and speech breathing, although within types of vocalization (nonspeech vocalization, babbling, true word production) no differences were apparent. Whereas rest breathing was characterized by tight coupling of rib cage and abdominal movement (average correlation coefficients usually exceeded .90), speech breathing exhibited weak coupling (the correlation coefficient ranged widely, but averaged about .60). Furthermore, speech production by these toddlers included the occurrence of both rib cage and abdominal paradoxing, which are observed infrequently in adult speakers. These results fail to support the suggestion that speech emerges from the extant coordinative organization of rest breathing. Rather, even in its earliest stages breathing for speech and voice exhibits kinematic properties distinct from those of other observed behaviors.

    Indium-111 leukocyte scanning of the abdomen (IAS) was performed in 10 patients with ulcerative colitis and in 39 patients with Crohn's disease involving the small intestine (in 25 occasions) and/or the colon (17 cases). Radionuclide uptake by the gut was seen in 84% of the patients with active inflammation. We compared the extent of the disease displayed by IAS with the findings obtained by either radiological or endoscopic studies or at surgery. In two-thirds of the patients, the IAS gave an accurate evaluation of the extent of the disease (sensitivity 68%). False-positive IASs were not seen in small bowel disease (specificity 100%), but were observed on 4 occasions on the colon (specificity 86%). The intensity of the radionuclide uptake could not be correlated with the clinical activity of the disease as evaluated by the Crohn's disease activity index. These results suggest that IAS is not superior to the standard procedures used to detect and localize inflammatory bowel disease and that IAS cannot replace these techniques. However, the simplicity of IAS and the complete lack of complications associated with its use render it useful in the evaluation of the extent and distribution of inflammation in some patients, mainly those with severe disease in whom standard diagnostic procedures would be contraindicated.

    Significant percentage of today's knowledge of ancient Egyptian medicine has been acquired from papyri left behind from various periods of Egyptian history. The longest and the most comprehensive is the Ebers papyrus, kept at the University Museum of Leipzig, which was written more than one thousand years before Hippocrates (c. 460-377 BC). One of the riddles among the prescriptions of the Ebers papyrus Eb20 has been used in order to remove the so called "wemyt" weremit from the abdomen with the help of a drink, which consists of "jnnk", Conyza dioscoridis in milk or sweet beer. The authors assume that the disease could be an infection of Schistosoma haematobium and/or Schistosoma mansoni. Nowadays the tea of Conyza dioscoridis is widely used as an important part of traditional medicine against rheumatism, intestinal distention and cramps, as well as an antiperspirant, and with external use for wound healing. The authors' intent is to interpret the efficacy of the above-mentioned ancient prescription with the help of modern medical and pharmaceutical knowledge. PMID:26639646

    This report presents the feasibility of phase-recordered contrast-enhanced three-dimensional MR angiography in 32 consecutive patients with vascular abnormalities in the chest and abdomen. To suppress motion artifacts due to respiratory corruption, a phase-reordering technique was introduced so that the low frequency components of the phase data were obtained first during the imaging period. Image quality and degree of motion suppression were assessed by four radiologists independently without information on breath-holding time. Abnormalities were detected in 30 cases (93.8%), and their extent was correctly assessed in 28 cases (87.5%). More confident assessment was possible in abnormalities of the pulmonary vessels and thoracic aorta than in those of the abdominal aorta and portal venous system. With phase reordering, more than 20 seconds of breath-holding ensured image quality sufficient to correctly assess the vascular abnormalities. While this technique is easy and requires only single breath-holding, it can provide excellent MRA without slice-to-slice spatial misregistration.

    Acute superior mesenteric venous thrombosis is rare. With advance in CT venography, angiography and diagnostic laparoscopy, the incidence of acute superior mesenteric venous thrombosis has increased worldwide with more access to early diagnosis. The use of anticoagulation medication, interventional radiology, and damage control approach has resulted in better clinical outcomes. At present, the new step-up approach for acute superior mesenteric venous thrombosis includes CT venography as the main diagnostic technique, anticoagulation as the cornerstone of therapy, local transcatheter thrombolytic therapy as the key recanalization method, and adjunctive use of arterial spasmolysis and various endovascular manipulation and damage control surgery by intestinal resection plus jejunostomy and ileostomy or open abdomen. This strategy may further improve clinical outcomes. This review will present the most recent advance in this strategy.

    Acute pancreatitis is one of the main causes of intra-abdominal hypertension (IAH). IAH contributes to multiple physiologic alterations and leads to the development of abdominal compartment syndrome (ACS) that induces multiorgan failure. We report a case of ACS in a patient with severe acute pancreatitis. A 44-year-old man who was admitted in a drunk state was found to have severe acute pancreatitis. During management with fluid resuscitation in an intensive care unit, drowsy mentality, respiratory acidosis, shock requiring inotropes, and oliguria developed in the patient, with his abdomen tensely distended. With a presumptive diagnosis of ACS, abdominal decompression through percutaneous catheter drainage was performed immediately. The intraperitoneal pressure measured with a drainage catheter was 31 mm Hg. After abdominal decompression, the multiorgan failure was reversed. We present a case of ACS managed with percutaneous catheter decompression. PMID:25325011

    Sinusitis is a common patient complaint that carries with it a large economic burden. It is one of the most common reasons patients visit their primary care physician. Acute bacterial rhinosinusitis (ABRS) can be distinguished from other forms of rhinosinusitis based on symptom duration of <4 weeks in a patient with purulent rhinorrhea associated with facial pain or pressure. Native upper aerodigestive tract bacteria are the most common etiologic agents. Treatment of ABRS is targeted primarily at symptom improvement. Amoxicillin can be used based on the clinical scenario and patient comorbidities. Computed tomographic scans are reserved for complicated presentations or when there is concern for intracranial extension or other complications. A systematic approach to ABRS will allow for improved patient quality of life and a decreased overall economic burden of this common entity.

  4. Severe acute pancreatitis: Clinical course and management.

    Beger, Hans G; Rau, Bettina M

    Severe acute pancreatitis (SAP) develops in about 25% of patients with acute pancreatitis (AP). Severity of AP is linked to the presence of systemic organ dysfunctions and/or necrotizing pancreatitis pathomorphologically. Risk factors determining independently the outcome of SAP are early multi-organ failure, infection of necrosis and extended necrosis (>50%). Up to one third of patients with necrotizing pancreatitis develop in the late course infection of necroses. Morbidity of SAP is biphasic, in the first week strongly related to early and persistence of organ or multi-organ dysfunction. Clinical sepsis caused by infected necrosis leading to multi-organ failure syndrome (MOFS) occurs in the later course after the first week. To predict sepsis, MOFS or deaths in the first 48-72 h, the highest predictive accuracy has been objectified for procalcitonin and IL-8; the Sepsis-Related Organ Failure Assessment (SOFA)-score predicts the outcome in the first 48 h, and provides a daily assessment of treatment response with a high positive predictive value. Contrast-enhanced CT provides the highest diagnostic accuracy for necrotizing pancreatitis when performed after the first week of disease. Patients who suffer early organ dysfunctions or at risk of developing a severe disease require early intensive care treatment. Early vigorous intravenous fluid replacement is of foremost importance. The goal is to decrease the hematocrit or restore normal cardiocirculatory functions. Antibiotic prophylaxis has not been shown as an effective preventive treatment. Early enteral feeding is based on a high level of evidence, resulting in a reduction of local and systemic infection. Patients suffering infected necrosis causing clinical sepsis, pancreatic abscess or surgical acute abdomen are candidates for early intervention. Hospital mortality of SAP after interventional or surgical debridement has decreased in high volume centers to below 20%.

    A secondary fuel delivery system for delivering a secondary stream of fuel and/or diluent to a secondary combustion zone located in the transition piece of a combustion engine, downstream of the engine primary combustion region is disclosed. The system includes a manifold formed integral to, and surrounding a portion of, the transition piece, a manifold inlet port, and a collection of injection nozzles. A flowsleeve augments fuel/diluent flow velocity and improves the system cooling effectiveness. Passive cooling elements, including effusion cooling holes located within the transition boundary and thermal-stress-dissipating gaps that resist thermal stress accumulation, provide supplemental heat dissipation in key areas. The system delivers a secondary fuel/diluent mixture to a secondary combustion zone located along the length of the transition piece, while reducing the impact of elevated vibration levels found within the transition piece and avoiding the heat dissipation difficulties often associated with traditional vibration reduction methods.

    Appendiceal mucocele is a rare cause of acute abdomen. Mucinous appendiceal neoplasms represent 0.2–0.7% of all appendix specimens. The aim of this study is to report a case of a mucinous appendiceal neoplasm presented as acute appendicitis, discussing the clinical and surgical approach in the emergency setting. A 72-year-old female patient was admitted to the emergency department with a clinical examination indicative of acute abdomen. The patient underwent abdominal computed tomography scan which revealed a cystic lesion in the right iliac fossa measuring 8.3 × 5.2 × 4.1 cm, with calcified walls, and a mean density indicative of high protein content. The patient was taken to the operating room and a right hemicolectomy was performed. The postoperative course was unremarkable. The histopathological examination revealed a low-grade mucinous appendiceal neoplasm with negative regional lymph nodes. Ultrasound and CT are useful in diagnosing appendiceal mucocele and synchronous cancers in the emergency setting. The initial operation should include appendectomy and resection of the appendicular mesenteric fat along with any fluid collection for cytologic examination. During urgent appendectomy it is important to consider every mucocele as malignant in order to avoid iatrogenic perforation causing pseudomyxoma peritonei. Although laparotomy is recommended, the laparoscopic approach is not contraindicated. PMID:27066284

    We report a case of a 63-year-old man, with a previous history of hypertension and glucose intolerance associated troncular obesity that was emergently admitted to our Institution for evaluation of a severe, constant posterior chest pain which radiated anteriorly and dyspnoea with a suspected diagnosis of acute aortic dissection. A CT scan of thorax and abdomen demonstrated a dissection starting just below left succlavian artery and extending downward to the left renal artery, involving the celiac tripod and superior mesenteric artery. The dissection was classified as Stanford B, De Bakey III. Moreover, CT scan of abdomen revealed incidentally a left adrenal tumor of 25 mm of diameter. An emergent prosthetic graft was placed just below the origin of the left succlavian artery up-to the diaphragmatic hiatus. Furthermore, a diagnostic evaluation of the mass revealed an increase of cortisol production, and a diagnosis of Cushing's syndrome was done and the patient underwent an adrenalectomy via laparotomic approach. We report an association of acute aortic dissection of acute aortic dissection type B associated to Cushing's syndrome.

    2016-01-01

    Summary Adrenal haemorrhage is a rare cause of adrenal crisis, which requires rapid diagnosis, prompt initiation of parenteral hydrocortisone and haemodynamic monitoring to avoid hypotensive crises. We herein describe a case of bilateral adrenal haemorrhage after hemicolectomy in a 93-year-old female with high-grade colonic adenocarcinoma. This patient’s post-operative recovery was complicated by an acute hypotensive episode, hypoglycaemia and syncope, and subsequent computed tomography (CT) scan of the abdomen revealed bilateral adrenal haemorrhage. Given her labile blood pressure, intravenous hydrocortisone was commenced with rapid improvement of blood pressure, which had incompletely responded with fluids. A provisional diagnosis of hypocortisolism was made. Initial heparin-induced thrombocytopenic screen (HITTS) was positive, but platelet count and coagulation profile were both normal. The patient suffered a concurrent transient ischaemic attack with no neurological deficits. She was discharged on a reducing dose of oral steroids with normal serum cortisol levels at the time of discharge. She and her family were educated about lifelong steroids and the use of parenteral steroids should a hypoadrenal crisis eventuate. Learning points: Adrenal haemorrhage is a rare cause of hypoadrenalism, and thus requires prompt diagnosis and management to prevent death from primary adrenocortical insufficiency. Mechanisms of adrenal haemorrhage include reduced adrenal vascular bed capillary resistance, adrenal vein thrombosis, catecholamine-related increased adrenal blood flow and adrenal vein spasm. Standard diagnostic assessment is a non-contrast CT abdomen. Intravenous hydrocortisone and intravenous substitution of fluids are the initial management. A formal diagnosis of primary adrenal insufficiency should never delay treatment, but should be made afterwards.

    Acute disseminated encephalomyelitis is a demyelinating disease, typically occurring in children following a febrile infection or a vaccination. Primary and secondary immune responses contribute to inflammation and subsequent demyelination, but the exact pathogenesis is still unknown. Diagnosis of acute disseminated encephalomyelitis is strongly suggested by temporal relationship between an infection or an immunization and the onset of neurological symptoms. Biopsy is definitive. In general, the disease is self-limiting and the prognostic outcome is favorable with anti-inflammatory and immunosuppressive agents. Locked-in syndrome describes patients who are awake and conscious but have no means of producing limb, speech, or facial movements. Locked-in syndrome is a rare complication of acute disseminated encephalomyelitis. We present a case of incomplete locked-in syndrome occurring in a 34-year-old male secondary to acute disseminated encephalomyelitis. Our case is unique, as acute disseminated encephalomyelitis occurred in a 34-year-old which was poorly responsive to immunosuppression resulting in severe disability. PMID:24977089

    PubMed

    Estenssoro, Elisa; Dubin, Arnaldo

    2016-01-01

    Acute respiratory distress syndrome (ARDS) is an acute respiratory failure produced by an inflammatory edema secondary to increased lung capillary permeability. This causes alveolar flooding and subsequently deep hypoxemia, with intrapulmonary shunt as its most important underlying mechanism. Characteristically, this alteration is unresponsive to high FIO2 and only reverses with end-expiratory positive pressure (PEEP). Pulmonary infiltrates on CXR and CT are the hallmark, together with decreased lung compliance. ARDS always occurs within a week of exposition to a precipitating factor; most frequently pneumonia, shock, aspiration of gastric contents, sepsis, and trauma. In CT scan, the disease is frequently inhomogeneous, with gravitational infiltrates coexisting with normal-density areas and also with hyperaerated parenchyma. Mortality is high (30-60%) especially in ARDS associated with septic shock and neurocritical diseases. The cornerstone of therapy lies in the treatment of the underlying cause and in the use mechanical ventilation which, if inappropriately administered, can lead to ventilator-induced lung injury. Tidal volume = 6 ml/kg of ideal body weight to maintain an end-inspiratory (plateau) pressure = 30 cm H2O ("protective ventilation") is the only variable consistently associated with decreased mortality. Moderate-to-high PEEP levels are frequently required to treat hypoxemia, yet no specific level or titration strategy has improved outcomes. Recently, the use of early prone positioning in patients with PaO2/FIO2 = 150 was associated with increased survival. In severely hypoxemic patients, it may be necessary to use adjuvants of mechanical ventilation as recruitment maneuvers, pressure-controlled modes, neuromuscular blocking agents, and extracorporeal-membrane oxygenation. Fluid restriction appears beneficial. PMID:27576283

    Summary Background Identifying patients at risk for acute respiratory distress syndrome (ARDS) before their admission to intensive care is crucial to prevention and treatment. The objective of this study is to determine the performance of an automated algorithm for identifying selected ARDS predisposing conditions at the time of hospital admission. Methods This secondary analysis of a prospective cohort study included 3,005 patients admitted to hospital between January 1 and December 31, 2010. The automated algorithm for five ARDS predisposing conditions (sepsis, pneumonia, aspiration, acute pancreatitis, and shock) was developed through a series of queries applied to institutional electronic medical record databases. The automated algorithm was derived and refined in a derivation cohort of 1,562 patients and subsequently validated in an independent cohort of 1,443 patients. The sensitivity, specificity, and positive and negative predictive values of an automated algorithm to identify ARDS risk factors were compared with another two independent data extraction strategies, including manual data extraction and ICD-9 code search. The reference standard was defined as the agreement between the ICD-9 code, automated and manual data extraction. Results Compared to the reference standard, the automated algorithm had higher sensitivity than manual data extraction for identifying a case of sepsis (95% vs. 56%), aspiration (63% vs. 42%), acute pancreatitis (100% vs. 70%), pneumonia (93% vs. 62%) and shock (77% vs. 41%) with similar specificity except for sepsis and pneumonia (90% vs. 98% for sepsis and 95% vs. 99% for pneumonia). The PPV for identifying these five acute conditions using the automated algorithm ranged from 65% for pneumonia to 91 % for acute pancreatitis, whereas the NPV for the automated algorithm ranged from 99% to 100%. Conclusion A rule-based electronic data extraction can reliably and accurately identify patients at risk of ARDS at the time of hospital

  12. The muscle pattern of the Drosophila abdomen depends on a subdivision of the anterior compartment of each segment

    2012-01-01

    In the past, segments were defined by landmarks such as muscle attachments, notably by Snodgrass, the king of insect anatomists. Here, we show how an objective definition of a segment, based on developmental compartments, can help explain the dorsal abdomen of adult Drosophila. The anterior (A) compartment of each segment is subdivided into two domains of cells, each responding differently to Hedgehog. The anterior of these domains is non-neurogenic and clones lacking Notch develop normally; this domain can express stripe and form muscle attachments. The posterior domain is neurogenic and clones lacking Notch do not form cuticle; this domain is unable to express stripe or form muscle attachments. The posterior (P) compartment does not form muscle attachments. Our in vivo films indicate that early in the pupa the anterior domain of the A compartment expresses stripe in a narrowing zone that attracts the extending myotubes and resolves into the attachment sites for the dorsal abdominal muscles. We map the tendon cells precisely and show that all are confined to the anterior domain of A. It follows that the dorsal abdominal muscles are intersegmental, spanning from one anterior domain to the next. This view is tested and supported by clones that change cell identity or express stripe ectopically. It seems that growing myotubes originate in posterior A and extend forwards and backwards until they encounter and attach to anterior A cells. The dorsal adult muscles are polarised in the anteroposterior axis: we disprove the hypothesis that muscle orientation depends on genes that define planar cell polarity in the epidermis.

    Acute kidney injury following immersion or near-drowning is rarely described and no data from Malaysia have been found. We report a case of acute kidney injury following a near-drowning event. A 20-year-old man who recovered from near-drowning in a swimming pool 5 days earlier presented to our clinic with abdominal pain, anorexia, nausea and polyuria. Dipstick urinalysis showed a trace of blood. The serum creatinine level was 10-fold higher than the normal range. A bedside ultrasound showed features suggestive of acute tubular necrosis. He is then referred to the hospital with the diagnosis of acute kidney injury with the possibility of acute tubular necrosis secondary to near-drowning. We suggest that any patient presenting after immersion or near-drowning to be should assessed for potential acute kidney injury.

    1975-06-01

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    2015-01-01

    Chondrosarcomas are malignant bone tumors originating in cartilage. Chondrosarcoma is the third most common malignant bone tumor after multiple myeloma and osteosarcoma. About 75% of chondrosarcomas are primary lesions. The remaining 25% belong to special categories such as histologic variants and secondary forms. A secondary chondrosarcoma is one that appears in a pre-existing benign chondral lesion; the different types of secondary chondrosarcomas include solitary osteochondroma, multiple osteochondromatosis, enchondroma, the different types of enchondromatosis, and primary synovial chondromatosis. The incidence of this malignant transformation varies widely in function of the type of lesion. In this article, we discuss and illustrate the different types of secondary chondrosarcomas, placing special emphasis on the imaging findings that should alert to these lesions and give radiologists a key role in the diagnosis, management, and follow-up of these patients.

Secondary metabolites such as alkaloids, iridoids and phenolics generally produced by plants for their defence mechanisms have been implicated in the therapeutic properties of most medicinal plants. Hence, quantification of these metabolites will aid to discover new and effective drugs from plant sources and also to scientifically validate the existing traditional practices. Quantification of large group of phytochemicals such as phenolics and flavonoids is quantified in this context.

Information in this paper permits rapid determination of blur spot size, and resulting image quality degradation, due to secondary color for a refracting lens system that has been designed with normal optical glasses and is free of primary color (achromatic). Included here is a brief description of the basic theory involved and an example of how the plotted data are used. PMID:20856581

    A pool boiling phenomenon referred to as secondary boiling effects is discussed. Based on the experimental trends, a mechanism is proposed that identifies the parameters that lead to this phenomenon. Secondary boiling effects refer to a distinct decrease in the wall superheat temperature near the critical heat flux due to a significant increase in the heat transfer coefficient. Recent pool boiling heat transfer experiments using femtosecond laser processed Inconel, stainless steel, and copper multiscale surfaces consistently displayed secondary boiling effects, which were found to be a result of both temperature drop along the microstructures and nucleation characteristic length scales. The temperature drop is a function of microstructure height and thermal conductivity. An increased microstructure height and a decreased thermal conductivity result in a significant temperature drop along the microstructures. This temperature drop becomes more pronounced at higher heat fluxes and along with the right nucleation characteristic length scales results in a change of the boiling dynamics. Nucleation spreads from the bottom of the microstructure valleys to the top of the microstructures, resulting in a decreased surface superheat with an increasing heat flux. This decrease in the wall superheat at higher heat fluxes is reflected by a "hook back" of the traditional boiling curve and is thus referred to as secondary boiling effects. In addition, a boiling hysteresis during increasing and decreasing heat flux develops due to the secondary boiling effects. This hysteresis further validates the existence of secondary boiling effects.
