Renaudin First page of article [source] Ultrasonographic Screening of Clinically-suspected Necrotizing FasciitisACADEMIC EMERGENCY MEDICINE, Issue 12 2002Zui-Shen Yen MD Objective: To determine the accuracy of ultrasonography for the diagnosis of necrotizing fasciitis. Methods: This study was a prospective observational review of patients with clinically-suspected necrotizing fasciitis presenting to the emergency department of an urban (Taipei) medical center between October 1996 and May 1998. All patients underwent ultrasonographic examination, with the ultrasonographic diagnosis of necrotizing fasciitis based on the criterion of a diffuse thickening of the subcutaneous tissue accompanied by a layer of fluid accumulation more than 4 millimeters in depth along the deep fascial layer, when compared with the contralateral position on the corresponding normal limb. The final diagnosis of necrotizing fasciitis was determined by pathological findings for patients who underwent fasciotomy or biopsy results for patients managed nonoperatively. Results: Data were collected for 62 patients, of whom 17 (27.4%) were considered to suffer from necrotizing fasciitis. Ultrasonography revealed a sensitivity of 88.2%, a specificity of 93.3%, a positive predictive value of 83.3%, a negative predictive value of 95.4%, and an accuracy of 91.9% as regards the diagnosis of necrotizing fasciitis. Conclusions: Ultrasonography can provide accurate information for emergency physicians for the diagnosis of necrotizing fasciitis. [source] Three-dimensional ultrasonographic diagnosis and hysteroscopic management of a viable cesarean scar ectopic pregnancyJOURNAL OF OBSTETRICS AND GYNAECOLOGY RESEARCH (ELECTRONIC), Issue 6 2007Sebiha Özkan Abstract Implantation of conception material within a cesarean section scar is an extremely rare form of ectopic pregnancy with devastating complications, such as uterine rupture and intractable bleeding. Both 2-D and 3-D transvaginal ultrasonographic devices are used adequately for precise diagnosis, but there is still a lack of consensus concerning management strategies. No therapeutic modality is suggested to be entirely efficacious and safe for preserving uterine integrity. We present here a 29-year-old woman with vaginal bleeding and a gestational sac with a viable embryo of 6 weeks of age that was implanted in a cesarean section scar. Serum ,-hCG levels were 16 792 mIU/mL. Following an unsuccessful treatment course of systemic methotrexate, the patient underwent operative hysteroscopy. Minimally invasive hysteroscopic resection of the ectopic gestational mass without major complication appears to be an alternative therapeutic approach with minimal morbidity and preservation of future fertility.

Mesich Objective: To investigate the relationship between endocrinopathies and diagnosis of gall bladder mucocele in dogs via a retrospective case-control study. Methods: Records of 78 dogs with a surgical or ultrasonographic diagnosis of gall bladder mucocele were examined for the presence or absence of hyperadrenocorticism, hypothyroidism and diabetes mellitus. Two age- and breed-matched controls for each gall bladder mucocele dog (156 total control dogs) were examined for the same concurrent diseases. A matched case-control analysis was performed using conditional logistic regression. Results: The odds of mucocele in dogs with hyperadrenocorticism were 29 times that of dogs without hyperadrenocorticism (P=0·001; 95 per cent CI 3·8, 219·9). No difference was found between dogs with and without diabetes mellitus. Although a significant association was found between gall bladder mucocele and hypothyroidism, potential observation bias was also identifi ed. Clinical Significance: Hyperadrenocorticoid dogs that were presented for acute illness with laboratory evidence of hepatobiliary disease should undergo evaluation for the presence of a biliary mucocele. Dogs diagnosed with a gall bladder mucocele should be screened for concurrent hyperadrenocorticism if clinical suspicion exists. [source] Obstetric risk factors and persistent increases in brain parenchymal echogenicity in preterm infantsBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 9 2004Arsenio Spinillo Objective To assess the risk of persistent (>7 days) increases in brain parenchymal echogenicity in preterm infants and their association with known obstetric risk factors. Design Case,control study of prospectively collected data. Setting A University hospital in Northern Italy. Population Eighty-five singleton infants between 24 and 34 weeks of gestation with a cranial ultrasonographic diagnosis of persistently increased parenchymal echogenicity without development of cystic degeneration, and 170 control infants with negative cranial ultrasonographic findings. Methods A comparison of the prevalence of selected obstetric risk factors between infants with persistent echo-dense lesions and negative controls. Main outcome measures Odds ratios of persistent echo-dense lesions including first-degree interactions between variables. Results After adjusting for birthweight, logistic regression analysis showed that the only factor associated with an increased risk of persistent brain echo-dense lesions in infants was multiple courses of antenatal steroids (OR = 2.14, 95% CI = 1.11,4.15, P= 0.024). In this group, the risk of persistent echo-dense lesions was particularly high in: (i) mothers receiving dexamethasone rather than betamethasone (P value for interaction = 0.015) and (ii) after expectant management of pre-eclampsia or intrauterine growth retardation (P value for interaction = 0.03). Conclusions Multiple doses of antenatal steroids, especially dexamethasone, could influence the prevalence of persistent increases in brain parenchymal echogenicity in preterm infants. [source] Experience with laparoscopic ultrasonography for defining tumour resectability in carcinoma of the pancreatic head and periampullary regionBRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 8 2001Dr A. M. Taylor Background: Computed tomography (CT) is currently the most widely available staging investigation for pancreatic tumours. However, the accuracy of CT for determining tumour resectability is variable and can be poor. Laparoscopic ultrasonography (LUS) is potentially a more accurate method for disease staging. The authors' experience of LUS for staging carcinoma of the pancreatic head and periampullary region is described. Methods: Fifty-one patients with potentially resectable pancreatic tumours defined at CT underwent further investigation with LUS. Twenty-seven patients subsequently had an open laparotomy. The evaluations of tumour resectability at CT and LUS were compared with the operative findings. Results: At LUS, 24 patients were considered to have resectable tumours, 21 non-resectable tumours and six patients were shown to have no pancreatic tumour mass. Twenty-two patients deemed to have a resectable tumour at LUS underwent surgery. Twenty patients were confirmed to have resectable disease and two patients had non-resectable disease. A further five patients underwent surgery. In all five the ultrasonographic diagnosis was confirmed at surgery (four patients with non-resectable disease and no pancreatic tumour in one patient). LUS prevented unnecessary extensive surgery in 53 per cent of patients. For the 22 patients who underwent surgery for potentially resectable disease, the positive predictive value of LUS for defining tumour resectability was 91 per cent. Conclusion: LUS is an accurate additional investigation for defining tumour resectability and directing management in patients with potentially resectable carcinoma of the pancreatic head or periampullary region. © 2001 British Journal of Surgery Society Ltd [source] | ||||||||||
