Ovarian Cycle01:27

Ovarian Cycle

4.2K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Nephrotic Syndrome I : Introduction

689
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Acute Coronary Syndrome I: Introduction

1.1K
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Hormonal Control of the Ovarian Cycle01:30

Hormonal Control of the Ovarian Cycle

7.0K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle.  At puberty, GnRH secretion increases in both frequency and...

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...

Restless Leg Syndrome and Night Terrors01:27

Restless Leg Syndrome and Night Terrors

583
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

Summary
This summary is machine-generated.

Ovarian hyperstimulation syndrome (OHSS) is a rare but serious complication of assisted reproductive technology (ART). While new triggers have reduced OHSS incidence, it remains a concern, necessitating continued research into its classification, pathophysiology, and treatment.

Area of Science:

  • Reproductive Endocrinology
  • Obstetrics & Gynecology

Background:

  • Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of assisted reproductive technology (ART).
  • The popularity of ART has led to an increase in OHSS cases.
  • Severe and fatal cases of OHSS, though infrequent, have been reported.

Purpose of the Study:

  • To summarize the classification of OHSS.
  • To review the pathophysiology of OHSS.
  • To outline the current treatment strategies for OHSS.

Main Methods:

  • Review of existing literature on OHSS.
  • Analysis of trends in OHSS incidence.
  • Synthesis of current understanding of OHSS mechanisms and management.

Main Results:

  • The incidence of OHSS has increased with the rise of ART.
  • Substitution of human chorionic gonadotropin (hCG) trigger with gonadotropin-releasing hormone (GnRH) agonist trigger has decreased OHSS rates.
  • OHSS has not been completely eliminated despite changes in ART protocols.

Conclusions:

  • OHSS remains a significant concern in ART.
  • Understanding OHSS classification, pathophysiology, and treatment is crucial for patient safety.
  • Further research may be needed to fully mitigate OHSS risks.
