Summary
The incidence of rectal foreign bodies in adults shows seasonal variation, with a peak observed in October. This finding suggests potential links to environmental or behavioral changes during the fall season.
Area of Science:
- Medical research
- Public health
- Epidemiology
Background:
- Human behavior and functioning exhibit seasonal patterns, prompting increased research interest.
- Understanding seasonality is crucial for public health initiatives and medical practice.
Purpose of the Study:
- To investigate seasonal variations in the occurrence of rectal foreign bodies among adults in the United States.
- To analyze trends in rectal foreign body admissions using a comprehensive inpatient database.
Main Methods:
- Utilized the Nationwide Inpatient Sample database (2009-2011) for patient identification (age ≥18).
- Employed Edward's recognition and estimation of cyclic trend method to assess seasonality.
- Applied Z-test for statistical comparison of seasonal incidences.
Main Results:
- Identified 3,359 hospitalizations for rectal foreign bodies between 2009 and 2011.
- Observed a peak incidence in October, with a peak-to-low ratio of 1.20 (95% CI: 1.10-1.32).
Conclusions:
- Limited data exists on the seasonality of rectal foreign bodies.
- Further research is needed to confirm findings and explore potential contributing factors like daylight, climate, or behavioral changes.
- Increased clinical suspicion during fall may aid in prompt diagnosis and management.

01:25Assessment of the Rectum and Anus
1.7K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

01:27Assessing Body Temperature - Rectal
14.2K
Rectal temperature measurement is considered the most precise method for assessing core body temperature and typically registers higher than oral temperature. For adults, the rectal thermometer should be inserted 1 to 1.5 inches into the rectum to obtain the most accurate reading.
Follow these steps for rectal temperature assessment:
Step 1: Perform hand hygiene and don clean gloves to prevent cross-infection.
Step 2: Position the patient in a side-lying position to better visualize the rectal...

2.3K
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
