Out of 2802 respiratory panels, 1258 (44.8%) turned out positive.

Community perception of malaria in a vulnerable municipality in the Colombian Pacific.

Background: Malaria primarily affects populations living in poor socioeconomic conditions, with limited access to basic services, deteriorating environmental conditions, and barriers to accessing health services. Control programmes are designed without participation from the communities involved, ignoring local knowledge and sociopolitical and cultural dynamics surrounding their main health problems, which implies imposing decontextualized control measures that reduce coverage and the impact of interventions. The objective of this study was to determine the community perception of malaria in the municipality of Olaya Herrera in the Colombian Pacific.

Pseudo skin flash on VMAT in breast radiotherapy: Optimization of virtual bolus thickness and HU values.

Purpose: Optimisation strategies for volumetric modulated arc therapy (VMAT) in most treatment planning systems for breast cancer do not account for patient positioning, breathing, or anatomical changes. To overcome this limitation, a pseudo-skin flash strategy using a virtual bolus has been proposed. Using this strategy, we determined optimal thickness and value of Hounsfield units (HU) assigned to the virtual bolus to ensure adequate CTV irradiation.

Association of vitamin D and vitamin B with cognitive impairment in elderly aged 80 years or older: a cross-sectional study.

Background: The present study aimed to assess the association of vitamin D and vitamin B with cognitive impairment in elderly people.

Methods: The data were obtained from a cross-sectional study that included individuals aged 80 years or older living in the urban and rural areas of the cities of Siderópolis and Treviso in the state of Santa Catarina, Brazil. In total, 165 elderly people were included in the analysis.

In vitro development of Haemoproteus columbae (Haemosporida: Haemoproteidae), with perspectives for genomic studies of avian haemosporidian parasites.

The evolutionary origin of wildlife and human malaria parasites (Plasmodium spp.) has been discussed for several decades. The lack of genomic data about species of wildlife haemosporidian parasites related to Plasmodium limits the number of taxa available for phylogenetic analysis.

Prevalence, resistance patterns, and risk factors for antimicrobial resistance in bacteria from retail chicken meat in Colombia.

As a step toward implementing the Colombian Integrated Program for Antimicrobial Resistance Surveillance (COIPARS), this study aimed to establish the baseline antimicrobial resistance patterns of Salmonella serovars, Escherichia coli, and Enterococcus spp. isolates in retail poultry meat from independent stores and from a main chain distributor center. MICs of the isolates were determined for antimicrobials used both in humans and animals, using an automated system.

Sublingual [corrected] misoprostol as first-line care for incomplete abortion in Burkina Faso.

Objective: To explore 400-μg sublingual misoprostol as primary treatment in lower-level facilities with no previous experience providing postabortion care.

Methods: Women presenting with incomplete abortion were offered a single dose of 400-μg sublingual misoprostol. Incomplete abortion was defined as uterine size consistent with fewer than 12 weeks of gestation, open cervical os, and reports of past or present history of vaginal bleeding.

Variation between experienced observers in the interpretation of accident and emergency radiographs.

Skill mix and role extension initiatives have highlighted the difficulty of establishing quality standards for the accuracy of plain film reporting. An acceptable performance might be one which is indistinguishable from that of a group of experienced consultant radiologists. In order to assess the feasibility of setting such a standard, the variation between experienced observers must first be established.

Castleman's disease of the erector spinae muscle.

Castleman's disease, angio-follicular lymph node hyperplasia, is a relatively rare benign tumour. It typically arises in the mediastinum. We report a unique case arising in the erector spinae muscle.

Bilateral three-compartment wrist arthrography in patients with unilateral wrist pain: findings and implications for management.

Bilateral three-compartment wrist arthrography was performed in 30 patients with unilateral posttraumatic wrist pain to assess the incidence of bilateral findings. The mean age of patients was 30 (range 18-55) years. Thirty-three percent of patients were normal bilaterally, 30% had unilateral communication in the symptomatic wrist, 30% had communications in both the symptomatic and asymptomatic wrists and 7% had communication in the asymptomatic wrist only.

Prone oblique positioning for computed tomographic arthrography of the shoulder.

Computed tomographic arthrography (CTA) of the shoulder is currently the best investigation of the unstable shoulder. 47 patients had CTA in the prone oblique position to assess its ability to demonstrate both anterior and posterior capsular mechanisms simultaneously. The first five patients were also scanned supine oblique to allow direct comparison with the prone oblique position.

Magnetic resonance imaging of septic sacroiliitis.

Five cases of septic sacroiliitis diagnosed by magnetic resonance imaging (MRI) are presented. Imaging was performed between 2 and 14 days after onset of symptoms and consisted of varying combinations of coronal short tau inversion recovery (STIR), axial T2-weighted spin echo (SE), and coronal and axial pre- and postcontrast T1-weighted SE scans. Abnormalities included demonstration of sacroiliac joint effusions, bone oedema and adjacent inflammation as high signal on STIR and T2-weighted SE scans, and identification of abscesses in two cases as rim-enhancing lesions anterior to the joint on gadolinium-enhanced T1-weighted SE scans.

Case report 745: Synovial lipoma arborescens.

A case is presented of lipoma arborescens of the knee with an atypical, sudden onset. Arthrography and ultrasound confirmed a synovially based lesion in the suprapatellar pouch. CT enabled a preoperative diagnosis of lipoma arborescens to be made, which was confirmed by surgical excision of a fronded fatty mass.

Villous adenoma of the common hepatic duct: the role of ultrasound in management.

A case of villous adenoma of the common hepatic duct causing obstructive jaundice, where the diagnosis was made by ultrasound guided percutaneous biopsy is reported. At surgery ultrasonography was used to define the extent and operability of the tumour.

Growing bone cysts in long-term hemodialysis.

All patients with chronic renal failure undergoing hemodialysis for more than 10 years in the university hospitals of Leuven were selected for this study. The medical records and radiographs of these 21 patients were studied retrospectively. Skeletal surveys were examined for the presence and location of subchondral cysts.

Tortuous vertebral artery--onset of symptoms during pregnancy.

A case of tortuous vertebral artery causing neurological symptoms and expansion of an intervertebral foramen in a 33-year-old pregnant woman is described. The literature on this condition is reviewed.

Bronchoalveolar lavage cell counts as a predictor of short term outcome in pulmonary sarcoidosis.

Sixty seven patients with biopsy proven pulmonary sarcoidosis were prospectively studied to determine whether single point bronchoalveolar lavage cell counts were a useful indicator of functional outcome and whether repeated lavage helped in management. The mean follow up period was 25 (range 13-37) months. No patient was having corticosteroid treatment at the time of initial bronchoalveolar lavage.
