Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...

Disorders of the Female Reproductive System

The female reproductive system can be affected by several disorders, including Premenstrual Syndrome (PMS), Premenstrual Dysphoric Disorder (PMDD), endometriosis, and various forms of cancer. PMS and PMDD are cyclical conditions that cause physical and emotional distress, with symptoms that include edema, mood swings, and food cravings. PMDD is a more severe form of PMS characterized by increased symptom severity that peaks during the luteal phase and tends to improve or resolve shortly after...
Appendicitis01:19

Appendicitis

Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Intestinal Obstruction II: Pathophysiology01:07

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...

Summary

Enterobius vermicularis, a common pinworm, can cause rare peritoneal infections presenting as abdominal pain. Diagnosis and treatment with mebendazole resolved symptoms, highlighting its role in differential diagnosis.

Area of Science:

  • Parasitology
  • Gastroenterology
  • Gynecology

Background:

  • Enterobiasis, caused by Enterobius vermicularis (pinworm), is a common intestinal infection.
  • Extraintestinal infections are rare but can involve the female genital tract and peritoneal cavity.
  • Peritoneal enterobiasis may present asymptomatically or with abdominal pain.

Observation:

  • A 32-year-old patient presented with cyclical lower abdominal pain, initially suspected as endometriosis.
  • Diagnostic autofluorescence laparoscopy revealed extensive peritoneal deposits not typical for endometriosis.
  • Histological examination confirmed granulomas caused by Enterobius vermicularis eggs.

Findings:

  • The patient received mebendazole treatment for peritoneal enterobiasis.
  • Post-treatment, the patient became asymptomatic.
  • Second-look laparoscopy showed complete resolution of peritoneal changes.

Implications:

  • Enterobius vermicularis should be considered in the differential diagnosis of conditions presenting with abdominal pain, especially when endometriosis is suspected.
  • This case underscores the importance of considering parasitic infections in unexplained abdominal symptoms.
  • Prompt diagnosis and antiparasitic treatment can lead to complete symptom resolution and prevent misdiagnosis.
