Summary
Intestinal nematode infections, like Ascariasis, impact over a billion people globally, causing malnutrition and reduced work capacity. This case highlights a rare diagnosis in an elderly traveler returning from Greece.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Parasitology
Background:
- Intestinal nematodes are a significant global health concern, particularly in areas with inadequate sanitation.
- These infections, while often non-fatal, lead to substantial morbidity, including malnutrition and decreased work capacity.
Observation:
- An 80-year-old male presented with symptoms following recent travel to Greece.
- Clinical examination and endoscopic procedures were performed.
Findings:
- The patient was diagnosed with an Ascaris Lumbricoides infection.
- Clinical endoscopic images were obtained to document the findings.
Implications:
- This case underscores the importance of considering parasitic infections in elderly travelers returning from endemic regions.
- Highlights the need for diagnostic vigilance for Ascariasis even in non-traditional demographics.
- Emphasizes the clinical relevance of parasitic infections in contributing to global health burdens.

Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Large Intestine
The large intestine is divided into three main regions: the cecum, colon, and rectum. Extending from the ileocecal valve to the anus, it frames the small intestine on three sides.
The ileocecal sphincter, a mucous membrane fold, guards the opening from the ileum to the large intestine. This valve permits material from the small intestine to pass into the large intestine. Attached to the ileocecal valve is the cecum. This small pouch, approximately 6 cm long, has a twisted, coiled tube known as...

Anthelminthic Agents
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...
Drugs Affecting GI Tract Motility: Other Laxatives
Laxatives are primarily used to alleviate constipation, a common gastrointestinal disorder characterized by infrequent bowel movements and difficulty passing stools. They work by various mechanisms to increase the volume or frequency of bowel movements. The primary modes of action of laxatives include increasing stool bulk, softening the stool, stimulating intestinal motility, and osmotically drawing water into the intestines.
