Dry Friction01:30

Dry Friction

996
Dry friction occurs between two solid surfaces in contact as they attempt to move relative to one another. In daily life, dry friction is encountered in various forms, such as when walking on the ground, sliding an object across a table, or rubbing hands together. Despite its ubiquity, the underlying mechanisms behind dry friction are not readily visible.
To illustrate this concept, imagine a wooden crate resting on a rough, non-uniform horizontal surface. When an external force is applied to...

Drying Shrinkage01:21

Drying Shrinkage

385
When hardened concrete is exposed to air with a relative humidity of less than 100 percent, it begins to lose the free water within its capillaries. As this water evaporates, the water initially adsorbed onto the calcium silicate hydrates migrates towards these now empty spaces and eventually evaporates as well. Over time, as more water leaves, the volume of the concrete decreases, a phenomenon known as drying shrinkage.
A portion of this drying shrinkage can be reversed; if the concrete is...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

808
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Irritable Bowel Syndrome I: Introduction

1.1K
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
Altered...

Characteristics of Dry Friction01:21

Characteristics of Dry Friction

996
Dry friction occurs when two solid surfaces slide against each other without any lubrication or fluid present. It causes resistance when pushing objects along a surface, like a gardener pushing a wheelbarrow. The force applied to move the cart causes dry friction between the wheel and the ground.
Before the wheelbarrow starts moving, the static frictional force acts tangentially to the contact surface, opposing the force that is about to induce the motion. This frictional force prevents the...

Inflammatory Bowel Disease I: Ulcerative Colitis

1.1K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

This summary is machine-generated.

A rare case of small bowel obstruction caused by a large dried persimmon phytobezoar in an elderly female is presented. Surgical intervention was required after conservative treatment failed to resolve the obstruction.

Area of Science:

  • Gastroenterology
  • Surgical Pathology

Background:

  • Dried persimmon consumption is common in East Asia.
  • Phytobezoars, particularly from persimmons, are a rare cause of small bowel obstruction (2-4%).

Observation:

  • An 87-year-old female presented with symptoms of small bowel obstruction.
  • The obstruction was attributed to a large phytobezoar formed from a dried astringent persimmon.

Findings:

  • Initial conservative management for the phytobezoar-induced obstruction was unsuccessful.
  • Enterotomy was performed for the successful removal of the large dried persimmon phytobezoar.

Implications:

  • This case highlights the potential for large phytobezoars from dried persimmons to cause significant gastrointestinal obstruction.
  • It underscores the importance of considering phytobezoars in the differential diagnosis of small bowel obstruction, especially in at-risk populations.
  • Surgical intervention may be necessary when conservative measures fail.
