Abdominal Ultrasound (abdominal + ultrasound)
Selected AbstractsENDOSCOPIC NECROSECTOMY UNDER DIRECT VISION AFTER ENDOSCOPIC ULTRASOUND-GUIDED CYSTGASTROSTOMY FOR ORGANIZED PANCREATIC NECROSISDIGESTIVE ENDOSCOPY, Issue 1 2008Takeshi Hisa A 56-year-old man was referred for an enlarging pancreatic pseudocyst that developed after severe acute pancreatitis with gallstones. Abdominal ultrasound showed a huge cystic lesion with a large amount of solid high echoic components. Arterial phase contrast-enhanced computed tomography scan revealed arteries across the cystic cavity. Stents were placed after endoscopic ultrasound-guided cystgastrostomy; however, the stents were obstructed by necrotic debris, and secondary infection of the pseudocyst occurred. Therefore, the cystgastrostomy was dilated by a dilation balloon, and a forward-viewing endoscope was inserted into the cystic cavity. Many vessels and a large amount of necrotic debris existed in the cavity. Under direct vision, all necrotic debris was safely removed using a retrieval net and forceps. One year after this procedure, there was no recurrence. Our case indicates that peripancreatic fat necrosis can cause exposure of vessels across/along the cystic cavity, and blind necrosectomy should be avoided. [source] Alanine transaminase rather than abdominal ultrasound alone is an important investigation to justify cholecystectomy in patients presenting with acute pancreatitisHPB, Issue 5 2010Kerry Anderson Abstract Objectives:, The aims of this study were to investigate the predictive value of an elevated level of alanine transaminase (ALT) for biliary acute pancreatitis (AP) and to reconsider the role of abdominal ultrasound (AUS). Methods:, All patients admitted to Christchurch Public Hospital with AP between July 2005 and December 2008 were identified from a prospectively collected database. Peak ALT within 48 h of presentation was recorded. Aetiology was determined on the basis of history, AUS and other relevant investigations. Results:, A total of 543 patients met the inclusion criteria. Patients with biliary AP had significantly higher median (range) ALT than those with non-biliary causes (200 units/l [63,421 units/l] vs. 33 units/l [18,84 units/l]; P < 0.001). An ALT level of >300 units/l had a sensitivity of 36%, specificity of 94%, positive predictive value of 87% and positive likelihood ratio of 5.6 for gallstones. An elevated ALT and negative AUS had a probability of 21,80% for gallstones. Conclusions:, An elevated ALT strongly supports a diagnosis of gallstones in AP. Abdominal ultrasound effectively confirms this diagnosis; however, a negative ultrasound in the presence of a raised ALT does not exclude gallstones. In some patients consideration could be given to proceeding to laparoscopic cholecystectomy based on ALT alone. [source] Renal abscess in a dog with transient diabetes mellitusJOURNAL OF SMALL ANIMAL PRACTICE, Issue 1 2003R. S. Hess A nine-year-old, intact female dalmatian with diabetes mellitus and a renal abscess is described. The renal abscess was treated surgically by nephrectomy, and the diabetes mellitus resolved with ovariohysterectomy. Abdominal ultrasound and ultrasound-guided aspiration of the abscess were helpful in establishing a diagnosis. To the authors'knowledge, this is the first report of a renal abscess in a dog with diabetes mellitus. [source] Compound melanocytic nevus arising in a mature cystic teratoma of the ovaryPATHOLOGY INTERNATIONAL, Issue 11 2001Naoto Kuroda A 28-year-old woman complained of irregular menstruation. Abdominal ultrasound and magnetic resonance imaging (MRI) examinations revealed a cystic tumor in the left ovary. A histological examination of the resected ovary revealed that the lesion was a mature cystic teratoma. In this tumor, components such as skin with appendages, a thyroid gland, mucosa of the digestive tract and a submandibular gland were observed. Interestingly, compound melanocytic nevus was also present in the skin component. To the best of our knowledge, this is the sixth reported case of nevus arising in a mature cystic teratoma of the ovary. Despite the extreme rarity of such a lesion, pathologists should recognize the possibility of such lesions occurring in ovarian teratoma. [source] Emergency laparoscopic splenectomy for haemoperitoneum because of ruptured primary splenic pregnancy: a case report and review of literatureANZ JOURNAL OF SURGERY, Issue 1-2 2010Federico Biolchini Abstract Background:, Primary abdominal pregnancies are potentially life-threatening, particularly without an accurate preoperative diagnosis. Case:, A 41-year-old woman presented to the emergency room with 2 days-lasting left upper quadrant abdominal pain, irradiated to the left shoulder. An urine ,-human chorionic gonadotropin test was positive. Transvaginal sonography raised a suspicion of ectopic pregnancy. The patient was then submitted to abdominal laparoscopy that revealed no sign of active bleeding or ectopic pregnancy. Because of worsening of abdominal pain and progressive anaemia, the patient underwent abdominal ultrasound and multislice computerized tomography scan (TC) that showed the presence of a mass at the superior splenic pole with haemoperitoneum. The patient was taken to the operating room and submitted to a laparoscopic total splenectomy. The post-operative course was uneventful, and the patient was discharged 8 days after intervention. Conclusion:, Abdominal pregnancy should be considered in the differential diagnosis of acute abdomen in women of reproductive age. Abdominal ultrasound and computerized tomography studies must be performed before operative treatment if an ectopic pregnancy is suspected and no intrauterine gestational sac could be showed on transvaginal sonography. [source] Small bowel tumours: a 10 year experience in four sydney teaching hospitalsANZ JOURNAL OF SURGERY, Issue 9 2004David S. Rangiah Background: Small bowel tumours are uncommon and can have a long delay prior to diagnosis. The present study aims to compare the use of computed tomography (CT) and contrast small bowel series (SBS) in their diagnosis and to outline the clinical features of small bowel tumours. Methods: A retrospective, case note study was conducted between 1990 and 2000 in four Sydney teaching hospitals. The data collected included clinical features, investigations and tumour characteristics. Results: One hundred and sixty-six people with small bowel tumours were identified (91 malignant; 75 benign). Malignant tumours consisted of adenocarcinomas (31%), carcinoid tumours (12%), lymphomas (7%) and leiomyosarcomas (5%). Benign tumours consisted of adenomas (22%), hamartomas (13%), leiomyomas (4%), inflammatory polyps (4%) and hyperplastic polyps (2%) and a benign schwannoma (1%). Adenocarcinomas were mainly located in the duodenum (P < 0.001) and carcinoid tumours in the ileum (P < 0.001). Malignant tumours were associated with a higher proportion of symptoms (P < 0.01), signs (P < 0.001) and episodes of small bowel obstruction (P < 0.01). Abdominal CT scans demonstrated a greater sensitivity (87.7%) than SBS (72.9%) with a slightly improved sensitivity when both investigations were used (89.3%). Abdominal ultrasound had a lower sensitivity than both of the above investigations of 65%. Gastroduodenoscopy had a sensitivity of 90% for diagnosing duodenal tumours. Operative procedures were performed on 92 patients with a preoperative diagnosis made in 77%. Metastatic spread of malignant tumours was evident in 46%. The sites of spread were to lymph nodes (23%), liver (21%) and distant locations (2%) at diagnosis. Conclusions: Malignant small bowel tumours are more likely to produce symptoms and signs than benign tumours, particularly caused by small bowel obstruction. Abdominal CT is the best radiological investigation for small bowel tumours and has a slight complimentary effect with SBS in improving the chances of detection. Gastroduodenoscopy remains the best investigation of duodenal tumours. [source] Serum and 24-hour Urine Analysis in Adult Cyanotic and Noncyanotic Congenital Heart Disease PatientsCONGENITAL HEART DISEASE, Issue 3 2009Efrén Martínez-Quintana MD ABSTRACT Introduction., Glomerulopathy is a complication of congenital heart disease patients. The risk of developing renal impairment is particularly high in cyanotic patients. Objective., The aim of this study was to determine the prevalence of renal dysfunction and microalbumiuria in adult cyanotic and non cyanotic congenital heart disease patients. Methods., Fourteen cyanotic and 22 noncyanotic congenital heart disease patients were studied in the Adult Congenital Heart Disease Unit at the Complejo Hospitalario Universitario Insular-Materno Infantil. Demographic characteristics, complete blood count, and 24-hour urianalysis were obtained, including abdominal ultrasound in those with cyanosis. Results., No differences were seen between age (years) (27.4 ± 8.2; 26.4 ± 8.3; P = .71), sex, size, weight, or glomerular filtration rate (mL/min/1.73 m2) (81.1 ± 22.9 vs. 84.9 ± 9.2, P = .482) between cyanotic and noncyanotic patients. However, Eisenmenger patients had significantly impaired renal function when compared with noncyanotic patients (73.0 ± 17.3 vs. 84.9 ± 9.2 mL/min/1.73 m2, P = .023). Significant differences were obtained in oxygen saturation (%) (83.8 ± 5.8 vs. 97.8 ± 0.8; P = .000), hematocrit (%) (59.3 ± 8.1 vs. 40.9 ± 8.5; P = .000), platelets (103/µL) (161.5 ± 70.5 vs. 277.9 ± 57.6; P = .000), serum uric acid (mg/dL) (7.5 ± 2.3 vs. 5.6 ± 1.5; P = .008) and microalbuminuria (mg/24 hours) (12.8 [0, 700.2] vs. 2.4 [0, 18.9]; P = .000) between cyanotic and noncyanotic patients. Five cyanotic patients (35.7%) had microalbuminuria (>30 mg/24 hours) and three of them (21.4%) proteinuria (>1 g/24 hours). No significant differences were seen between serum and urine parameters between cyanotic patients who had microalbuminuria (>30 mg/24 hours) and those cyanotic patients who did not have it (<30 mg/24 hours). Conclusions., Renal impairment is frequently seen in congenital heart disease patients, being associated occasionally with proteinuria and microalbuminuria in cyanotic ones.

An ALT level of >300 units/l had a sensitivity of 36%, specificity of 94%, positive predictive value of 87% and positive likelihood ratio of 5.6 for gallstones. An elevated ALT and negative AUS had a probability of 21,80% for gallstones. Conclusions:, An elevated ALT strongly supports a diagnosis of gallstones in AP. Abdominal ultrasound effectively confirms this diagnosis; however, a negative ultrasound in the presence of a raised ALT does not exclude gallstones. In some patients consideration could be given to proceeding to laparoscopic cholecystectomy based on ALT alone. [source] Intra-abdominal sequestration of the lung and elevated serum levels of CA 19-9: a diagnostic pitfallHPB, Issue 1 2004C Armbruster Background Extralobar pulmonary sequestration is an uncommon congenital abnormality that is rarely diagnosed after the age of 40 years. We describe a 64-year-old woman with an intra-abdominal sequestration of the lung and elevated carbohydrate antigen (CA) 19-9 serum levels. Case outline On abdominal ultrasound a semi-solid cystic tumour was demonstrated that showed tight connection to the tail of the pancreas according to computed tomography. Cytological examination of the percutaneous biopsy did not lead to a definitive diagnosis. CA 19-9 serum levels were repeatedly elevated >250 IU/ml. With a tentative diagnosis of a tumour of the tail of pancreas the semi-solid cystic mass was resected. Frozen section histology suggested the diagnosis of pulmonary sequestration, which was confirmed by definitive histological examination. Immunohistochemical staining of the specimen with a specific monoclonal antibody against CA 19-9 showed strong immunoreactivity. Three months later the elevated CA 19-9 serum levels returned to normal. Discussion Elevated CA 19-9 serum levels have been described in benign pulmonary and mediastinal cystic lesions and in one case of extralobar intrathoracic lung sequestration. Although there is evidence that malignancies may arise in congenital lung cysts, CA 19-9 serum levels have not been investigated in such cases. Based on our results elevated serum values of CA 19-9 in combination with a cystic semi-solid mass in the left subphrenic space should include the differential diagnosis of extralobar pulmonary sequestration. [source] Bullous variant of Sweet's syndromeINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 11 2005Susanne Voelter-Mahlknecht MD A 69-year-old woman presented to our clinic as an emergency with erythematous, well-circumscribed plaques, which were partly vesicular, on her extremities and in her armpits, and additionally hemorrhagic blisters on both her palms and her fingers (Fig. 1a), which had developed 2 days after the first appearance of the skin lesions. The rapid onset of the lesions (within a few hours) and the pain associated with them were extremely troublesome to the patient. On admission she complained of fever, tiredness and being easily fatigued. Because of a urinary tract infection 1 month prior to admission, trospiumchloride was given. On clinical examination, body temperature was found to be above 38 °C and infraclavicular lymph nodes were enlarged but not tender. Figure 1. (a) Bullae on the patient's right hand. (b) Multiple partly confluent vesicles with neutrophilic granulocytes intraepidermally and a dense interstitial perivascular infiltration of neutrophilic granulocytes and lymphomononuclear cells (H&E, ×200) Normal or negative laboratory tests included blood counts, liver and kidney parameters, electrolytes and infection screen. Laboratory examination demonstrated minor leukocytosis and absolute neutrophilia (white blood cell count 10 440 cells/µL, neutrophils 8030 cells/µL). X-ray screening, abdominal ultrasound and laboratory investigations were all normal. There was no response to antibiotics when erythromycine was given. However, there was a good response to systemic corticosteroids. The patient was treated with a low dosage of prednisolone, beginning at 50 mg/day, which was then tapered off. Skin lesions resolved within 7 days. Histology from a lesion on the patient's left forearm showed a dense interstitial inflammatory infiltration consisting predominantly of neutrophilic granulocytes from the subepidermal layer to the middle of the reticular dermis. Inflammatory cells penetrated into both blood vessels and vessel walls; vasculitis was not prominent. In the lower dermis, perivascular infiltrations of lymphomononuclear cells were found. In addition, intraepidermally multiple partly confluent vesicles, with inclusions of neutrophilic granulocytes, were found, confirming the diagnosis of this rare variant of an acute febrile neutrophilic dermatosis (Fig. 1b). [source] Cytokine responses in a severe case of glandular fever treated successfully with foscarnet combined with prednisolone and intravenous immunoglobulinJOURNAL OF MEDICAL VIROLOGY, Issue 1 2009Christine Ma Abstract Viral loads and cytokine responses Epstein,Barr virus (EBV) were measured in an 18-year-old boy with severe glandular fever complicated by a mild anaemia, severe thrombocytopaenia and neutropaenia. Hepatosplenomegaly was detected by abdominal ultrasound in the presence of significant hepatitis. Cytokine testing demonstrated elevated cell-mediated Th1 (IFN-,, IL-12, sTNFR1, CXCL10, CXCL9 and CCL3) and humoral Th2 (IL-4) immune responses. Serum antibodies to EBV virus capsid antigen (VCA) IgM and IgG antibodies were detected, together with a raised EBV DNA level (up to about 70,000 DNA copies/mL) in the acute phase of the illness. This EBV DNA load decreased rapidly in response to treatment with a combination of foscarnet, intravenous immunoglobulin and prednisolone, and the boy's symptoms settled eventually after approximately 50 days of illness, following this combined antiviral and immune-modulating therapy. Detailed immunological, virological, haematological and biochemical laboratory parameters are presented to document this patient's severe EBV disease and eventual recovery. J. Med.

Mayhew Extrahepatic biliary obstruction (EHBO) was confirmed at surgery or necropsy in 22 cats. Biliary or pancreatic adenocarcinoma was diagnosed by histopathology in six cats and one cat had an undiagnosed mass in the common bile duct. The remaining 15 cats had at least one of a complex of inflammatory diseases including pancreatitis, cholangiohepatitis, cholelithiasis and cholecystitis. The most common clinical signs were jaundice, anorexia, lethargy, weight loss and vomiting. Hyperbilirubinaemia was present in all cases. Distension of the common bile duct and gall bladder was the most commonly observed finding on abdominal ultrasound. Nineteen cats underwent exploratory laparotomy for biliary decompression and diversion. Mortality in cats with underlying neoplasia was 100 per cent and, in those with non-neoplastic lesions, was 40 per cent. Long-term complications, in those that survived, included recurrence of cholangiohepatitis, chronic weight loss and recurrence of obstruction. Based on these findings, the prognosis for EHBO in cats must be considered guarded.

Statz DVM Abstract Objective: To describe the surgical repair and pre- and postoperative management of a peritoneopericardial diaphragmatic hernia (PPDH) in a pregnant dog. Case summary: A pregnant dog was presented for vomiting, lethargy, and pale mucous membranes. Pulsus paradoxus was noted on physical examination. The dog was diagnosed with a PPDH via thoracic radiographs, abdominal ultrasound, and an echocardiogram. The hernia was surgically repaired and the dog received supportive medical care until the puppies were old enough to be delivered via cesarean section. The mother and all puppies survived. New or unique information provided: This is the first report that describes the surgical repair and postoperative management of a PPDH in a pregnant dog. [source] Stage Migration in Dogs with LymphomaJOURNAL OF VETERINARY INTERNAL MEDICINE, Issue 5 2007Andrea B. Flory Background: Various diagnostic tests have been used to assign a clinical stage to dogs with lymphoma. As more sensitive staging methods are introduced, dogs are reclassified as having a higher disease stage, thereby affecting comparisons of dogs across differently staged clinical trials, and possibly, prognosis. Hypothesis: The addition of more sensitive staging tests causes stage migration in dogs with lymphoma. Animals: Fifty-nine client-owned dogs with previously untreated cytologically or histologically confirmed lymphoma Methods: For every dog, the World Health Organization stage classification (I-V) was based on 5 groupings of various diagnostic tests: A (physical examination [PE] and quantitative blood count [QBC]), B (PE, QBC, thoracic and abdominal radiographs), C (PE, complete blood count with blood-smear evaluation [CBC], thoracic and abdominal radiographs), D (PE, CBC, thoracic radiographs, abdominal ultrasound), and E (PE, CBC, thoracic radiographs, abdominal ultrasound, and bone-marrow cytology). Dogs were treated with doxorubicin-based protocols. Results: There was migration between all of the staging methods except D to E. However, the stage was not a predictor of remission rate, remission duration, or survival, regardless of staging method used. Conclusions and Clinical Importance: These data emphasized the need for standardized methods to determine the clinical stage in dogs with lymphoma. [source] Non-alcoholic fatty liver disease , a common and benign finding in octogenarian patientsLIVER INTERNATIONAL, Issue 6 2004Nadya Kagansky Kagansky N, Levy S, Keter D, Rimon E, Taiba Z, Fridman Z, Berger D, Knobler H, Malnick S. Non-alcoholic fatty liver disease , a common and benign finding in octogenarian patients. Liver International 2004: 24: 588,594. © Blackwell Munksgaard 2004 Abstract: Background: Non-alcoholic fatty liver disease (NAFLD), a common entity in the general population, has been shown to be linked with insulin resistance and metabolic syndrome. Several of the components of the metabolic syndrome are more common in the aged population. The aims of the current study were to determine in the aged, the prevalence and the clinical presentation of NAFLD, as well as the relation to the underlying metabolic abnormalities. Method: In this prospective study, we evaluated 91 octogenarians with a mean age of 85.56±3.76 years, who were admitted to the rehabilitation departments of a geriatric hospital. Clinical evaluation included: abdominal ultrasound (US), fasting glucose and lipid levels, serum liver enzymes, ferritin, iron and transferrin saturation. Elderly patients with NAFLD were compared with 46 young patients with NAFLD. Results: NAFLD diagnosed by US was a common finding in this aged population, is present in 42/91 patients (46.2%). No significant differences were observed between the patients with or without NAFLD in the following: age, gender, chronic illnesses, anthropometric parameters, lipid profile, fasting glucose levels, metabolic syndrome prevalence, serum levels of transaminases, ferritin and iron. Young patients with NAFLD had significantly higher serum levels of triglycerides and a significantly higher prevalence of glucose intolerance, obesity and the metabolic syndrome compared with the elderly patients with NAFLD. Conclusions: NAFLD was a common finding in our group of elderly patients and the prevalence was higher than reported in the general population. In contrast to the well-described association between the metabolic syndrome and NAFLD in the general population, we did not find this association in the aged group. In addition, none of the patients had stigmata of advanced liver disease. These data suggest that NAFLD is a common and benign finding in the elderly population, but is not associated with the metabolic syndrome. [source] Stiff Limb Syndrome: End of Spectrum or A Separate Entity?PAIN MEDICINE, Issue 3 2009Usha K. Misra DM ABSTRACT Background., Stiff-person syndrome is a rare disorder characterized by rigidity of axial or limb muscles with episodes of co-contraction of agonist and antagonist muscles during the spasms. In some patients axial or limb involvement may predominate and may have unusual manifestations. Design., Case report. Setting., Tertiary care teaching hospital. Patient., A 42-year-old farmer presented with seasonal occurrence of hiccup and vomiting during summer months for the last 3 years. He had painful lower limb spasms lasting for 2,3 minutes every 10,15 minutes for the past 20 days. His neurological examination was normal, erythrocyte sedimentation rate (ESR) was 50 mm at 1st hour, and cerebrospinal fluid protein 78 mg/dL without pleocytosis. Radiograph of chest, abdominal ultrasound, and craniospinal magnetic resonance imaging were normal. The patient improved on diazepam. Conclusion., Our patient is a forme fruste of stiff person syndrome with hiccups and vomiting due to diaphragmatic spasm. [source] Cholelithiasis in infant and pediatric heart transplant patientsPEDIATRIC TRANSPLANTATION, Issue 3 2002Andreas G. Sakopoulos Abstract: There have been numerous studies which demonstrate a relatively high incidence of gallstones in adult solid-organ transplant recipients receiving cyclosporin A (CsA) immunosuppression. The purpose of the present study was to investigate our experience with cholelithiasis in babies and children undergoing heart transplant (HTx). From May 1985 to December 1998, 311 neonatal and pediatric cardiac transplants were performed at our institution. Routine abdominal ultrasound was performed at 3 months, 1 yr, and bi-annually thereafter on all transplant recipients. Asymptomatic or symptomatic gallstone development was detected during abdominal ultrasound in 10 of 311 patients (3.2%). Eight of these 10 patients (80%) were transplanted when younger than 3 months of age. Eight per cent of all infants transplanted at < 3 months of age developed cholelithiasis (p < 0.05 compared to older age at HTx). Fifty per cent of gallstones were detected and treated within 6 months post-HTx, while the remaining 50% of patients with gallstones underwent cholecystectomy 3,6 yr later. Only 20% (two of 10) had symptoms of cholelithiasis/cholecystitis. Five patients (50%) underwent laparoscopic cholecystectomy. Only one patient older than 1 yr of age, who was symptomatic, underwent open cholecystectomy. There were no complications from surgery. There were no differences in liver function tests or cholesterol levels in transplant recipients with or without gallstones, and all mean values were within normal limits. Hence, although the incidence of pediatric post-transplant cholelithiasis in infant and pediatric heart transplant recipients is low, almost all occurrences are associated with HTx during early infancy and, because of this, patients in this group should be routinely screened. Laparoscopic or open cholecystectomy are extremely well tolerated and we recommend that surgery be performed when cholelithiasis is found in pediatric heart treatment patients. [source] Diagnostics and staging procedures in non-small cell lung cancer , is less more?THE CLINICAL RESPIRATORY JOURNAL, Issue 2 2008David Felix Heigener Abstract Introduction:, Non-small cell lung cancer (NSCLC) is a common cancer with approximately 85% of patients dying of the disease. The only chance for cure is in the early stages, when surgery or definite chemoradiotherapy can be performed. Diagnosis and staging of lung cancer can sometimes be difficult, particularly because the intrathoracic structures are not easy to reach. Objective:, This review discusses the diagnosis and staging of lung cancer. Results:, When performing lung cancer diagnostics, both invasive and noninvasive procedures, such as computed tomogram of the chest, bronchoscopy and abdominal ultrasound, are mandatory. Suspected mediastinal involvement should be differentiated: bulky disease, contralateral or high mediastinal nodes need further clarification by endoscopic ultrasound, endobronchial ultrasound or mediastinoscopy. In opposition to current guidelines, in all other cases, surgery should be performed. Positron emission tomography will gain even more importance when becoming widely accessible and might replace other imaging techniques in the future. In case of advanced disease, staging should be limited to those examinations with impact on symptom control. Conclusion:, The diagnosis and staging of lung cancer should involve both invasive and noninvasive diagnostic procedures. In the case of advanced disease, staging should be limited to those examinations with impact on symptom control, whereas early stages call for rapid and thorough diagnosis.

[source] Emergency laparoscopic splenectomy for haemoperitoneum because of ruptured primary splenic pregnancy: a case report and review of literatureANZ JOURNAL OF SURGERY, Issue 1-2 2010Federico Biolchini Abstract Background:, Primary abdominal pregnancies are potentially life-threatening, particularly without an accurate preoperative diagnosis. Case:, A 41-year-old woman presented to the emergency room with 2 days-lasting left upper quadrant abdominal pain, irradiated to the left shoulder. An urine ,-human chorionic gonadotropin test was positive. Transvaginal sonography raised a suspicion of ectopic pregnancy. The patient was then submitted to abdominal laparoscopy that revealed no sign of active bleeding or ectopic pregnancy. Because of worsening of abdominal pain and progressive anaemia, the patient underwent abdominal ultrasound and multislice computerized tomography scan (TC) that showed the presence of a mass at the superior splenic pole with haemoperitoneum. The patient was taken to the operating room and submitted to a laparoscopic total splenectomy. The post-operative course was uneventful, and the patient was discharged 8 days after intervention. Conclusion:, Abdominal pregnancy should be considered in the differential diagnosis of acute abdomen in women of reproductive age. Abdominal ultrasound and computerized tomography studies must be performed before operative treatment if an ectopic pregnancy is suspected and no intrauterine gestational sac could be showed on transvaginal sonography. [source] Generalized lymphedema in a sirolimus-treated renal transplant patientCLINICAL TRANSPLANTATION, Issue 2 2008Carmine De Bartolomeis Abstract:, Generalized lymphedema is an extremely rare effect of sirolimus therapy in renal transplant recipients. We describe the development of this complication in a 56-yr-old woman, who was given an experimental protocol with cyclosporine, sirolimus, steroids, and basiliximab. Following the protocol, after one month, the patient was randomized to the "sirolimus only" group, while cyclosporine was completely suspended and the oral steroids were continued. Three months later, the patient was admitted for severe lymphedema of the lower limbs, with significant weight increase, massive ascites and dyspnea, but excellent renal function. A chest radiography and an ultrasound study of the heart showed a moderate pleural and pericardial effusion. An abdominal ultrasound scan showed two small lymphoceles next to the transplanted kidney, confirmed with a CT scan. After sirolimus discontinuation the generalized lymphedema started to improve and three months later all the symptoms had disappeared. [source] Obese Patients with Abdominal Pain Presenting to the Emergency Department Do Not Require More Time or Resources for Evaluation Than Nonobese PatientsACADEMIC EMERGENCY MEDICINE, Issue 8 2005Timothy F. Platts-Mills MD Abstract Objectives: The authors describe the evaluation of obese and nonobese adult patients with abdominal pain presenting to an emergency department (ED). The hypothesis was that more ED and hospital resources are used to evaluate and treat obese patients. Methods: A prospective observational study of obese (n= 98; body mass index ,30 kg/m2) and nonobese (n= 176; body mass index < 30 kg/m2) adults presenting to the ED with abdominal pain was performed. ED length of stay (LOS) was the primary outcome. Secondary outcomes included use of laboratory tests, computed tomography, and ultrasonography, and rates of consultations, operations, and admissions. ED diagnoses were compared between the two groups. Results: Obese patients were older (41.9 vs. 38.3 years; p = 0.027) and more often female (69% vs. 51%; p = 0.003) than nonobese patients. There were no significant differences between obese and nonobese patients in either the primary or the secondary outcome measures. Obese patients were similar to nonobese patients in regard to LOS (457 vs. 486 minutes), laboratory studies (3.2 vs. 2.9 tests), abdominopelvic computed tomographic scans (30% vs. 31%), and abdominal ultrasounds (16% vs. 13%). Obese and nonobese patients were also similar in their rates of consultations (27% vs. 31%), operations (14% vs. 12%), and admissions (18% vs. 24%). No difference was found for LOS between obese and nonobese patients as evaluated by the Wilcoxon rank-sum test (p = 0.81). Logistic regression analysis controlling for baseline characteristics revealed no significant differences between obese and nonobese patients for secondary outcome variables. ED diagnoses for obese and nonobese patients were similar except that genitourinary diagnoses were less common in obese patients (8% vs. 21%; p = 0.01). Conclusions: In contradiction to the hypothesis, the results suggest that LOS and ED resource use in obese patients with abdominal pain are not increased when compared with nonobese patients. [source] O knowledge, where art thou?JOURNAL OF EVALUATION IN CLINICAL PRACTICE, Issue 6 2009Evidence, suspected appendicitis Abstract Background, Much effort goes into developing and publishing guidelines which physicians fail to implement. We feel that major discrepancies still exist between theory and reality and that the translational approach to this aspect of medical care has not yet established itself. We therefore decided to investigate in an exemplary audit how liberally inappropriate imaging is used in our emergency department (ED) to rule out acute appendicitis. Material and methods, Our electronic medical record ED database ,Qualicare' (http://www.qualidoc.ch) was searched using the ,appendicitis' sub data base. The frequency and accuracy of abdominal imaging was determined in patients with clinically suspected appendicitis on admission over a 5-year period at a university hospital emergency unit. Results, In total, 272 (41.2%) of the 577 patients were male and 305 (46.3%) were female. The attending physicians ordered abdominal X-rays in 133 patients, abdominal ultrasounds in 319, and abdominal computerized tomography (CT) scans in 93 patients. 125 patients underwent more than one imaging procedure. In all, 85/125 patients received a combination of X-rays, ultrasound and CT scanning! Discussion, Physicians are often insecure about indications for surgery and therefore order useless imaging procedures. The reliability of such procedures in excluding acute appendicitis is limited, which was confirmed by our results. Although evidence-based medicine guidelines exist, they are neglected for many reasons. Future academic efforts should therefore focus more on knowledge translation and the implementation of existing knowledge by heightening awareness, rather than on simply creating new guidelines.
