Hepatic cerebrospinal fluid pseudocyst mimicking hydatid liver disease: a case report

<p>Abstract</p> <p>Introduction</p> <p>An abdominal pseudocyst is a rare complication of a ventriculo-peritoneal shunt. Etiological factors include infection, obstruction and dislodgement. This is the first report of a hepatic cerebrospinal fluid pseudocyst mimicking hydatid liver disease.</p> <p>Case presentation</p> <p>We report the case of an 18-year-old Caucasian male patient who presented with a hepatic pseudocyst secondary to a ventriculo-peritoneal shunt, misdiagnosed as hydatid disease of the liver.</p> <p>Conclusion</p> <p>Hepatic pseudocysts, a rare complication of a ventriculo-peritoneal shunt, have similar clinical and radiological characteristics to those of hydatid liver disease. The formation of a pseudocyst should always be considered in patients with ventriculo-peritoneal shunts <it>in situ</it>.</p

Pancreatic Anastomosis Disruption Seven Years Postpancreaticoduodenectomy

We are reporting a case of a 22 year-old female patient, who underwent a pancreaticoduodenectomy previously for a solid-pseudopapillary neoplasm of the pancreas and was re-admitted seven years later with a pancreatic leak following disruption of the pancreatico-jejunal anastomosis. Exploratory laparotomy revealed a large collection at the level of the pancreatic anastomosis with major disruption of the pancreatico-jejunal anastomosis. The pancreatic stump was refreshed as well as the jejunal site and a duct to mucosa anastomosis was performed. She remains well with a follow up of 18 months

Successful one stage operation for a synchronous, duodenal carcinoma, colonic carcinoma and renal oncocytoma in an adult patient

We report a rare case of synchronous duodenal carcinoma, colonic carcinoma and renal oncocytoma successfully treated using a one-stage surgical approach. Potential risk factors for multiple primary malignancies associated with duodenal carcinoma are discussed. This case illustrates several practice points for consideration: 1. Patients presenting with small intestinal carcinomas have a higher than average chance of developing second primary tumors in other organs; this should be taken into consideration during staging and follow-up. 2. For full staging of patients presenting with small bowel tumors, upper and lower gastrointestinal endoscopy and PET scanning should be considered. 3. A one-stage surgical procedure can be used safely and successfully for multiple synchronous primary tumors

Community Acquired Bacteremia in Young Children from Central Nigeria- A Pilot Study

<p>Abstract</p> <p>Background</p> <p>Reports of the etiology of bacteremia in children from Nigeria are sparse and have been confounded by wide spread non-prescription antibiotic use and suboptimal laboratory culture techniques. We aimed to determine causative agents and underlying predisposing conditions of bacteremia in Nigerian children using data arising during the introduction of an automated blood culture system accessed by 7 hospitals and clinics in the Abuja area.</p> <p>Methods</p> <p>Between September 2008 and November 2009, we enrolled children with clinically suspected bacteremia at rural and urban clinical facilities in Abuja or within the Federal Capital Territory of Nigeria. Blood was cultured using an automated system with antibiotic removing device. We documented clinical features in all children and tested for prior antibiotic use in a random sample of sera from children from each site.</p> <p>Results</p> <p>969 children aged 2 months-5 years were evaluated. Mean age was 21 ± 15.2 months. All children were not systematically screened but there were 59 (6%) children with established diagnosis of sickle cell disease and 42 (4.3%) with HIV infection. Overall, 212 (20.7%) had a positive blood culture but in only 105 (10.8%) were these considered to be clinically significant. Three agents, <it>Staphylococcus aureus </it>(20.9%), <it>Salmonella typhi </it>(20.9%) and Acinetobacter (12.3%) accounted for over half of the positive cultures. <it>Streptococcus pneumoniae and non-typhi Salmonellae </it>each accounted for 7.6%. Although not the leading cause of bacteremia, <it>Streptococcus pneumoniae </it>was the single leading cause of all deaths that occurred during hospitalization and after hospital discharge.</p> <p>Conclusion</p> <p><it>S. typhi </it>is a significant cause of vaccine-preventable morbidity while <it>S. pneumoniae </it>may be a leading cause of mortality in this setting. This observation contrasts with reports from most other African countries where non-typhi Salmonellae are predominant in young children. Expanded surveillance is required to confirm the preliminary observations from this pilot study to inform implementation of appropriate public health control measures.</p

Primary undifferentiated embryonal sarcoma of the liver mistaken for hydatid disease

Primary undifferentiated embryonal sarcoma of the liver is a rare tumor with a peak incidence between the ages of 6 and 10 years. We report a case of a primary hepatic undifferentiated embryonal sarcoma arising in a 21-year-old male mistaken for hydatid disease of the liver. The rapid recurrence of this tumor along the site of attempted percutaneous drainage illustrates some important management points regarding this malignancy

Streptococcus intermedius causing infective endocarditis and abscesses: a report of three cases and review of the literature

<p>Abstract</p> <p>Background</p> <p><it>Streptococcus intermedius </it>is a member of the Streptococcus anginosus group. Clinical disease with <it>S. intermedius </it>is characterized by abscess formation and rarely endocarditis. Identification of <it>Streptococcus intermedius </it>is difficult, leading to the development of molecular methods to more accurately identify and characterize this organism.</p> <p>Case presentation</p> <p>Over a period of 6 months we encountered three cases of invasive <it>Streptococcus intermedius </it>infection presenting as hepatic abscesses, brain abscess, and endocarditis. We confirmed our microbiologic diagnosis through 16S sequencing and found a common virulence gene in each case.</p> <p>Conclusion</p> <p>Our report illustrates three different clinical manifestations due to <it>Streptococcus intermedius </it>infection that can be encountered in healthy individuals in a community hospital setting. To our knowledge, this is the first case of <it>Streptococcus intermedius </it>endocarditis confirmed by 16S sequencing analysis. The use of molecular methods may allow a better understanding of the epidemiology and pathogenesis of this organism.</p

Inflammatory pseudo-tumor of the liver: a rare pathological entity

Inflammatory pseudo-tumor (IPT) of the liver is a rare benign neoplasm and is often mistaken as a malignant entity. Few cases have been reported in the literature and the precise etiology of inflammatory pseudotumor remains unknown. Patients usually present with fever, abdominal pain and jaundice. The proliferation of spindled myofibroblast cells mixed with variable amounts of reactive inflammatory cells is characteristics of IPT. We reviewed the literature regarding possible etiology for IPT with a possible suggested etiology

Hospital performance and payment: impact of integrating pay-for-performance on healthcare effectiveness in Lebanon

Background: In 2014 the Lebanese Ministry of Public Health integrated pay-for-performance into setting hospital reimbursement tiers, to provide hospitalization service coverage for the majority of the Lebanese population. This policy was intended to improve effectiveness by decreasing unnecessary hospitalizations, and improve fairness by including risk-adjustment in setting hospital performance scores.Methods: We applied a systematic approach to assess the impact of the new policy on hospital performance. The main impact measure was a national casemix index, calculated across 2011-2016 using medical discharge and surgical procedure codes. A single-group interrupted time series analysis model with Newey ordinary least squares regression was estimated, including adjustment for seasonality, and stratified by case type. Code-level analysis was used to attribute and explain changes in casemix index due to specific diagnoses and procedures.Results: Our final model included 1,353,025 cases across 146 hospitals with a post-intervention lag-time of two months and seasonality adjustment. Among medical cases the intervention resulted in a positive casemix index trend of 0.11% per month (coefficient 0.002, CI 0.001-0.003), and a level increase of 2.25% (coefficient 0.022, CI 0.005-0.039). Trend changes were attributed to decreased cases of diarrhea and gastroenteritis, abdominal and pelvic pain, essential hypertension and fever of unknown origin. A shift from medium to short-stay cases for specific diagnoses was also detected. Level changes were attributed to improved coding practices, particularly for breast cancer, leukemia and chemotherapy. No impact on surgical casemix index was found.Conclusions: The 2014 policy resulted in increased healthcare effectiveness, by increasing the casemix index of hospitals contracted by the Ministry. This increase was mainly attributed to decreased unnecessary hospitalizations and was accompanied by improved medical discharge coding practices. Integration of pay-for-performance within a healthcare system may contribute to improving effectiveness. Effective hospital regulation can be achieved through systematic collection and analysis of routine data
