Dentinogenic ghost cell tumor associated with odontoma: report of a rare case and review of literature.

Dentinogenic ghost cell tumor (DGCT) is an uncommon odontogenic tumor considered to be the solid, tumorous variant of calcifying odontogenic cyst. DGCT is characterized by islands of ameloblastoma-like epithelial cells that resemble the enamel organ, the presence of ghost cells, and dentinoid material. This article reports a rare case of dentinogenic ghost cell tumor associated with an odontoma in an adult patient, with a review of the literature.

Deep transfer learning with multimodal embedding to tackle cold-start and sparsity issues in recommendation system.

Recommender systems (RSs) have become increasingly vital in the modern information era and connected economy. They play a key role in business operations by generating personalized suggestions and minimizing information overload. However, the performance of traditional RSs is limited by data sparseness and cold-start issues.

Analyzing central-line associated bloodstream infection prevention bundles in 22 countries: The results of ID-IRI survey.

Background: Because central line-associated bloodstream infections (CLABSIs) are a significant complication of central venous access, it is critical to prevent CLABSIs through the use of central line bundles. The purpose of this study was to take a snapshot of central venous access bundles in various countries.

Methods: The participants in intensive care units (ICUs) completed a questionnaire that included information about the health center, infection control procedures, and central line maintenance.

Midsagittal Plane First: Building a Strong Facial Reference Frame for Computer-Aided Surgical Simulation.

Purpose: A facial reference frame is a 3-dimensional Cartesian coordinate system that includes 3 perpendicular planes: midsagittal, axial, and coronal. The order in which one defines the planes matters. The purposes of this study are to determine the following: 1) what sequence (axial-midsagittal-coronal vs midsagittal-axial-coronal) produced more appropriate reference frames and 2) whether orbital or auricular dystopia influenced the outcomes.

Brucella melitensis Biovar 1 and Brucella abortus S19 Vaccine Strain Infections in Milkers Working at Cattle Farms in the Khartoum Area, Sudan.

Background: Human brucellosis is a preventable zoonoses that may become persistent, causing, if left untreated, severe localized disease. Occupational exposure to infected animals or animal products and consumption of fresh contaminated dairy are main risk factors.

Methods: One hundred farmworkers employed at two cattle farms one in Khartoum North and one in Omdurman were screened for the presence of specific antibodies and seropositive workers were invited to donate a blood sample for blood culture.

Lessons learned: cultural and linguistic enhancement of surveys through community-based participatory research.

Background: Surveys are frequently implemented in community-based participatory research (CBPR), but adaptation and translation of surveys can be logistically and methodologically challenging when working with immigrant and refugee populations.

Objective: To describe a process of participatory survey adaptation and translation.

Methods: Within an established CBPR partnership, a survey about diabetes was adapted for health literacy and local relevance and then translated through a process of forward translation, group deliberation, and back translation.

Physical activity among Somali men in Minnesota: barriers, facilitators, and recommendations.

Immigrants and refugees arrive to the United States healthier than the general population, but this advantage declines with increasing duration of residence. One factor contributing to this decline is suboptimal physical activity, but reasons for this are poorly understood. Persons from Somalia represent the largest African refugee population to the United States, yet little is known about perceptions of physical activity among Somali men.

Study of patients with community-acquired abscesses.

Background: Abscess incision and drainage (I&D) operations form the bulk of surgical procedures in the emergency department (ED). Nevertheless, epidemiologic, clinical, and bacteriology data are lacking for patients with abscesses presenting at Sudanese hospitals. Information also is unavailable on the magnitude of the problem of community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) and its susceptibility to the most commonly used antibiotics.

Efficacy of monotherapies and artesunate-based combination therapies in children with uncomplicated malaria in Somalia.

In order to guide the antimalarial treatment policy of Somalia, we conducted therapeutic efficacy studies of routinely used antimalarial monotherapies as well as artemisinin-based combination therapies (ACTs) for uncomplicated malaria in three sentinel sites during 2003-2006. Therapeutic efficacy of chloroquine (CQ), amodiaquine (AQ) and sulfadoxine/pyrimetahmine (SP) monotherapies, and artesunate plus SP (AS+SP) or AQ (AS+AQ) were evaluated in children 6 months to 10 years old with uncomplicated malaria. For the assessment of the monotherapies, 2003 WHO protocol with 14-day follow-up was used while the 2005 WHO protocol with 28-day follow-up was used for testing the ACTs.

Comamonas testosteroni meningitis in a patient with recurrent cholesteatoma.

Comamonas testosteroni, a lesser-known member of the genus, has shown little apparent capacity for causing infections in humans. We here present a case of purulent meningitis due to C. testosteroni, which occurred in a patient who had recurrent cholesteatoma.
