Bystander intervention is associated with reduced early mortality among injury victims in Cameroon.

Despite high injury mortality rates, Cameroon currently lacks a formal prehospital care system. In other sub-Saharan African low and middle-income countries, Lay First Responder (LFR) programs have trained non-medical professionals with high work-related exposure to injury in principles of basic trauma care. To develop a context-appropriate LFR program in Cameroon, we used trauma registry data to understand current layperson bystander involvement in prehospital care and explore associations between current non-formally trained bystander-provided prehospital care and clinical outcomes.

Crystalloid resuscitation is associated with decreased treatment delays and improved systolic blood pressures in a blood-constrained setting.

Objectives: We analyzed resuscitation practices in Cameroonian patients with trauma as a first step toward developing a context-appropriate resuscitation protocol. We hypothesized that more patients would receive crystalloid-based (CB) resuscitation with a faster time to administration than blood product (BL) resuscitation.

Methods: We included patients enrolled between 2017 and 2019 in the Cameroon Trauma Registry (CTR).

Prevalence, clinical presentation, and risk factors of chronic venous disease in Cameroon: A general population-based study.

Introduction: Chronic venous disease is a global public health problem, with high morbidity and economic distress. There is scarcity of data on this disease in sub-Saharan Africa.

Methods: We conducted the first population-based study over a period of 20 months from 1st February 2020 to 30th September 2021 in the 10 regions of Cameroon.

Failure to receive prescribed imaging is associated with increased early mortality after injury in Cameroon.

Despite having the highest rates of injury-related mortality in the world, trauma system capacity in sub-Saharan Africa remains underdeveloped. One barrier to prompt diagnosis of injury is limited access to diagnostic imaging. As part of a larger quality improvement initiative and to assist priority setting for policy makers, we evaluated trauma outcomes among patients who did and did not receive indicated imaging in the Emergency Department (ED).

Building on Capacity Established through US Centers for Disease Control and Prevention Global Health Programs to Respond to COVID-19, Cameroon.

The COVID-19 pandemic has highlighted the need for resilient health systems with the capacity to effectively detect and respond to disease outbreaks and ensure continuity of health service delivery. The pandemic has disproportionately affected resource-limited settings with inadequate health capacity, resulting in disruptions in health service delivery and worsened outcomes for key health indicators. As part of the US government's goal of ensuring health security, the US Centers for Disease Control and Prevention has used its scientific and technical expertise to build health capacity and address health threats globally.

How trauma patients die in low resource settings: Identifying early targets for trauma quality improvement.

Background: Injury deaths in sub-Saharan Africa are among the world's highest, but hospital data rarely have sufficient granularity to direct quality improvement. We analyzed clinical care patterns among trauma patients who died in a prospective, multicenter sub-Saharan cohort to pinpoint trauma quality improvement intervention targets.

Methods: In-hospital trauma deaths in four Cameroonian hospitals between 2017 and 2019 were included.

Factors predicting in-hospital all-cause mortality in COVID 19 patients at the Laquintinie Hospital Douala, Cameroon.

Background: Despite being a global pandemic, little is known about the factors influencing in-hospital mortality of COVID-19 patients in sub-Saharan Africa. This study aimed to provide data on in-hospital mortality among COVID-19 patients hospitalized in a single large center in Cameroon.

Methods: A hospital-based prospective follow-up was conducted from March 18 to June 30, 2020, including patients >18 years with positive PCR for SARS-COV-2 on nasopharyngeal swab admitted to the Laquintinie Douala hospital COVID unit.

Associations between social determinants of health and interpersonal violence-related injury in Cameroon: a cross-sectional study.

Introduction: Risk factors for interpersonal violence-related injury (IPVRI) in low-income and middle-income countries (LMICs) remain poorly defined. We describe associations between IPVRI and select social determinants of health (SDH) in Cameroon.

Methods: We conducted a cross-sectional analysis of prospective trauma registry data collected from injured patients 15 years old between October 2017 and January 2020 at four Cameroonian hospitals.

Determinants of hearing loss severity in tympanic membrane perforations in a sub-Saharan African setting.

Background: Factors specific to sub-Saharan Africa could have an impact on tympanic membrane perforation characteristics. Obtaining precise information on these characteristics and determinants of hearing loss severity would enable better management.

Objective: To determine the relationship between characteristics of tympanic membrane perforation and subsequent hearing impairment.

Effect of HIV Infection and Highly Active Antiretroviral Therapy on Hearing Function: A Prospective Case-Control Study From Cameroon.

Importance: Human immunodeficiency virus (HIV) infection remains a major cause of morbidity and mortality worldwide. Many studies have found a higher prevalence of hearing impairment among HIV-positive individuals.

Objective: To investigate the effect of HIV and highly active antiretroviral treatment (HAART) on the hearing function in a Cameroonian population.

Aetiology of childhood hearing loss in Cameroon (sub-Saharan Africa).

Background: Severe hearing loss is a global problem affecting particularly developing countries. There is scarcity of recent published data on the epidemiology of childhood deafness in sub-Saharan Africa.

Objective: To determine the etiological profile of severe childhood deafness in Cameroon.

[Facial entomophtoromycosis: à propos of a case].

We report one case of rare facial entomophtoromycosis which occured in a young male patient of 16 years of age, in Cameroon. The clinical presentation was a central mass of the face. We show the interest of the diagnosis of this rare fungal infection through biopsy and its medical treatment.

[Management of laryngeal cancer in an ENT Service in subSaharan Africa].

Introduction: The management of cancers of the larynx remains a challenge to most ENT specialists in Cameroon due to a multitude of factors linked to their management. The aim of this study is to identify the important factors that militate against the proper management of these cancers and to propose solutions.

Materials And Methods: A retrospective study was carried out in the ENT service of the General Hospital of Douala over six years (April 1998 to June 2006).

[Masticatory pain-dysfunction syndrome apropos of 60 cases].

Costen syndroma or temporo-mandibular joint disorders is not welknow in the ENT service, despite the common presentation with otalgia. We therefore present 60 cases diagnose in our hospital and present clinical and therapeutic aspect.

[Early ENT manifestations of HIV infection/AIDS. An analysis of 76 cases observed in Africa].

Objective: The aim of this work is to describe the ENT clinical manifestations by which HIV positive patients inaugurate their AIDS-illness and to classify these manifestations in respect to the biological state of the infection.

Material And Method: It was a multicenter, prospective study carried out in the ENT services of Yaounde (Cameroon), between the period of September 2000 and June 2002. Included in this study were HIV patients who started their AIDS with an ENT illness.
