Insights

Diarrhoea diseases are a significant public health issue in Ghana, particularly affecting children under one year old. The study found that diarrhoea accounted for 4% of all illnesses and was more prevalent in non-poorest districts.

Area of Science:

  • Public Health
  • Epidemiology
  • Infectious Diseases

Background:

  • Diarrhoea diseases represent a major global public health challenge, causing nearly 1.7 billion cases annually.
  • In Ghana, diarrhoea is a leading cause of mortality in children under five, with approximately 14,000 deaths each year.

Purpose of the Study:

  • To analyze the morbidity patterns of diarrhoea diseases in Ghana's Central Region.
  • To identify demographic and socioeconomic factors associated with diarrhoea incidence.

Main Methods:

  • Retrospective review of health facility morbidity data from 2008 to 2012.
  • Extraction of monthly diarrhoea data by sex, age, and district from the District Health Information Management System.
  • Analysis of bloody diarrhoea data from surveillance reports using descriptive statistics and C2 threshold for aberrations.

Main Results:

  • Diarrhoea diseases constituted 4% of total morbidity (306,854 cases out of 7,642,431).
  • Infants under one year (8.4% proportionate morbidity rate) and males (4.4% pmr) were most affected.
  • Bloody diarrhoea represented 2.2% of cases, with low laboratory confirmation rates (0.7%). Cases peaked in June, and were higher in non-poorest districts.

Conclusions:

  • Diarrhoea significantly contributed to the overall disease burden in the Central Region of Ghana.
  • Morbidity rates decreased with age, and were higher in non-poorest districts.
  • The high proportion of untested bloody diarrhoea cases necessitates improved diagnostic practices, including stool sample testing.

Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents

Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...

Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents

Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.

Drugs for Treatment of Diarrhea-Predominant IBS01:17

Drugs for Treatment of Diarrhea-Predominant IBS

Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Drugs Affecting GI Tract Motility: Opioids as Antidiarrheal Agents

Diarrhea, a condition marked by frequent loose or watery bowel movements, can be triggered by multiple factors such as viral or bacterial infections, food intolerances, anxiety, medications, and digestive disorders. Symptoms may include abdominal pain, bloating, nausea, and cramping. Severe or prolonged diarrhea can lead to complications like electrolyte imbalances, malnutrition, and dehydration if left untreated.
Opioids, widely used antidiarrheal agents, mitigate diarrhea by slowing down...

Inflammatory Bowel Disease II: Crohn's Disease

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
