Article Synopsis
  • * In a cohort of 51 CRC patients from Rwanda, TP53 variants were found in 45.1% of cases, primarily of the missense type, with notable mutations including c.455dup, c.524G>A, and c.733G>A, and a predominance of specific mutation sequences.
  • * The study also revealed that most TP53 mutations were associated with the CMS2 subtype, suggesting that these variants may play a significant role in the development of this

Article Synopsis
  • Mutations in the TP53 gene are commonly found in various cancers, particularly in colorectal carcinoma.
  • The study utilized bioinformatics to identify mutation hotspots in the TP53 gene by comparing sequences from 50 healthy individuals to those from 50 patients with colon cancer.
  • Findings showed that the most frequent mutations were in exons 5 and 8, indicating an uneven distribution of mutations, and underscoring that not all structural changes in the gene lead to increased cancer susceptibility, highlighting a multifactorial approach to cancer pathology.

Background: Healthcare professionals constitute a critical component of clinical care services. To provide the expected service, they must continuously develop their profession through continuous learning. This kind of learning is recognized as continuing professional development (CPD).

Background: Depression is a significant global public health concern, affecting individuals across different age groups and cultural backgrounds. However, screening for depression remains an essential but often neglected aspect of healthcare, particularly in outpatient settings. This study aimed to assess the prevalence of depression among outpatients visiting the internal medicine department of the University Teaching Hospital of Kigali in Rwanda and evaluate the feasibility of implementing a depression screening program in this setting.

Background: Gastric cancer is the sixth most frequently diagnosed cancer and third in causing cancer-related death globally. The most frequently mutated gene in human cancers is TP53, which plays a pivotal role in cancer initiation and progression. In Africa, particularly in Rwanda, data on TP53 mutations are lacking.

Background: Colorectal cancer (CRC) has been ranked as the second most deadly cancer and the third most diagnosed cancer cases for the year 2020. Specifically for Romania, the number of CRC-related deaths in 2019 was estimated at 6307 people, with a standardized mortality rate of 33.8 per 100,000 inhabitants.

Article Synopsis
  • Cancer research in Rwanda accounts for less than 1% of Africa's total output, with limited studies on colorectal cancer (CRC), which predominantly affects younger females and often presents at an advanced stage.
  • Researchers conducted a study on CRC tissue mutations, focusing on specific genes, through Sanger sequencing of samples from 54 patients, revealing a high prevalence of low-grade tumors primarily in the rectum.
  • The study identified 27 genetic variants, including three novel deleterious mutations, and provided important genetic variations and clinical information regarding CRC in the Rwandan population.

Objective: The shortage of pathologists is a worldwide problem that is more severe in Africa. One of the solutions is the use of telepathology (TP); however, most of the TP systems are expensive and unaffordable in many developing countries. At the University Teaching Hospital of Kigali, Rwanda, we assessed the possibility of combining commonly available laboratory tools into a system that can be used for diagnostic TP using Vsee videoconferencing.

Aim: Mutation spectrum of TP53 in gastric cancer (GC) has been investigated world-widely, but a comparison of mutation spectrum among GCs from various regions in the world are still sparsely documented. In order to identify the difference of TP53 mutation spectrum in GCs in Eastern Europe and in East Asia, we sequenced TP53 in GCs from Eastern Europe, Lujiang (China), and Yokohama, Kanagawa (Japan) and identified the feature of TP53 mutations of GC in these regions.

Subjects And Method: In total, 689 tissue samples of GC were analyzed: 288 samples from East European populations (25 from Hungary, 71 from Poland and 192 from Romania), 268 from Yokohama, Kanagawa, Japan and 133 from Lujiang, Anhui province, China.

Background: Cervical cancer is a global public health problem with marked geographical disparity. High morbidity and mortality rates in developing countries are associated with low screening rates. In 2020, in Rwanda, 3.

Background: Lymphomas have been a global challenge for many decades and despite measures for prevention and management, the incidence continues to increase. There are two main categories, which are Non-Hodgkin's Lymphomas and Hodgkin's Lymphomas and most common etiologies are environmental, genetic alteration, radiation and some viruses.

Objective: To describe pathology characteristics of lymphomas in Rwanda based on Hematoxylin and Eosin stained glass slides and immuno histo chemistry, and classify them according to clinical aggressiveness.

Article Synopsis
  • The study investigates the prevalence of H. pylori infection in patients with gastritis and gastric adenocarcinoma using histopathological tissue samples from a hospital in Rwanda.
  • The research involved 307 cases diagnosed between 2016-2018, finding a high overall infection rate of 77.5%, with no significant association noted with age or sex.
  • The findings suggest that pathologists should routinely check for H. pylori in gastric biopsies, as the immunohistochemistry technique proved effective for detection to aid in timely treatment.

Purpose: In most low- and lower middle-income countries (LMICs), minimally invasive tissue sampling (MITS) is a relatively new procedure for identifying the cause of death (CoD). This study aimed to explore perceptions and acceptance of bereaved families and health-care professionals regarding MITS in the context of MITS initiation in Rwanda as an alternative to clinical autopsy.

Methods: This was a qualitative phenomenological study with thematic analysis.

  • Tuberculosis (TB) is caused by the bacteria Mycobacterium tuberculosis and can affect not only the lungs but also other organs, including bones, which can resemble other conditions.
  • A 9-year-old girl presented with an ulcerated heel and swollen foot, leading to the diagnosis of extrapulmonary TB after various tests, including a biopsy and special staining.
  • Clinicians in regions with high TB rates should consider skeletal TB in their diagnoses to ensure accurate detection and treatment, even though it is rare.

Introduction: Multiple hereditary exostoses (MHE) is a rare autosomal dominant disorder characterized by the presence of multiple skeletal deformities. They are painless slow-growing lesions. Malignant transformation tends to occur later in adulthood and has only been seen in 1-5% of patients.

We examined the possible risk factors for poor prognostic in cerebral malaria in 31 adults from Burundi, an area of high prevalence rate of HIV-1 infection. Depth of coma, temperature, vomiting, seizures, parasite load, or anaemia did not modify the outcome. High levels of creatinine, bilirubin, and/or lactates were indicators of poor prognostic.
