Echinococcosis in Tambool, Central Sudan: a knowledge, attitude and practice (KAP) study.

Introduction: In Sudan, echinococcosis (EC) is a chronic neglected zoonotic parasitic disease caused by Echinococcus granulosus. Studies have shown high prevalence rates in dogs (50-70%), camels (35%) and sheep, goats and cattle (10-11%). In total, 0.3-1.0% of humans in Central and South Sudan are infected with the G6 camel strain. This strain is almost exclusively the cause of human infections. The objective of this study was to explore knowledge, attitudes and practices (KAP) regarding the disease among people living around Tambool city, Central Sudan. Methods: A cross-sectional survey was conducted in three villages around the city of Tambool in Central Sudan. Three-hundred-and-twelve households were selected from the administrative unit of the area for participation in the study, of which 300 agreed to partake. A standardized questionnaire was designed to collect data on EC in animals, humans and the environment. The questionnaire domains were socio-demographic characteristics, KAP regarding echinococcosis. Results: The population surveyed showed that 68.7% (206/300) had never heard of the disease, while 31.3% (94/300) had heard about it. The level of knowledge among the 31.3% of those that had heard about the disease was excellent (69/94; 73.4%); so were their attitudes (76/94; 80.9%). However, the majority of the participants (64/94; 68%) showed poor practice regarding this disease, enhancing the odds for further propagation of parasite circulation in the animal and human populations at risk. Knowledge was found to be significantly associated with marital status. Practice was found to be significantly associated with occupation. Conclusions: There is a need for the implementation of a multidisciplinary program using the One Health approach to effectively control and prevent EC.

Complications of Anterior Cervical Fusion using a Low-dose Recombinant Human Bone Morphogenetic Protein-2.

OBJECTIVE: There are several reports, which documented a high incidence of complications following the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in anterior cervical fusions (ACFs). The objective of this study is to share our experience with low-dose rhBMP-2 in anterior cervical spine. METHODS: We performed a retrospective analysis of 197 patients who underwent anterior cervical fusion (ACF) with the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) during 2007-2012. A low-dose rhBMP-2 (0.7mg/level) sponge was placed exclusively within the cage. In 102 patients demineralized bone matrix (DBM) was filled around the BMP sponge. Incidence and severity of dysphagia was determined by 5 points SWAL-QOL scale. RESULTS: Two patients had prolonged hospitalization due to BMP unrelated causes. Following the discharge, 13.2%(n=26) patients developed dysphagia and 8.6%(n=17) patients complained of neck swelling. More than half of the patients (52.9%, n=9) with neck swelling also had associated dysphagia; however, only 2 of these patients necessitated readmission. Both of these patients responded well to the intravenous dexamethasone. The use of DBM did not affect the incidence and severity of complications (p>0.05). Clinico-radiological evidence of fusion was not observed in 2 patients. CONCLUSION: A low-dose rhBMP-2 in ACFs is not without risk. However, the incidence and severity of complications seem to be lower with low-dose BMP placed exclusively inside the cage. Packing DBM putty around the BMP sponge does not affect the safety profile of rhBMP-2 in ACFs.

Impact of elective versus emergent admission on perioperative complications and resource utilization in lumbar fusion.

BACKGROUND: The notion of higher complication rate and mortality in emergency surgeries is well established. There is a paucity of literature demonstrating the impact of emergent versus elective admissions for spinal surgery on the perioperative outcomes. We aim to evaluate the influence of the type of admission (elective or emergent) and day of surgery (same day versus other days within the emergent group) on the incidence, pattern of perioperative complications and hospital charges in the patients undergoing lumbar fusion for degenerative spine disease. METHODS: Data was obtained from the Nationwide Inpatient Sample (NIS) database between 2002 and 2011. We performed multivariate analysis to evaluate the impact of admission type and day of surgery on perioperative outcomes. RESULTS: A total of 266439 patients were identified. The majority of the admissions were elective (92.6%). Emergent admission comprised 7.4% of the total admission. Mean Charlson comorbidity index (CCI) was significantly higher in emergent and 'other days' (<0.001) groups. Emergent admission and surgery performed on the 'other days' were the independent risk factors for the higher incidence of the venous thromboembolic events, surgical site infection and wound dehiscence. The patients in the emergent and 'other days' surgery groups had a longer stay in the hospital (P<0.001). The mean total hospital charges were higher in the emergent admission and 'other days' surgery groups (P<0.001). CONCLUSIONS: 'Emergent admission' and surgery performed on the 'other days' in lumbar fusion are independent risk factors for the higher incidence of perioperative complications. Complicated hospital course and longer stay of the patients in the emergent admission and 'other days' group seems to be associated with higher total hospital charges.
