Disease Prevalence, Incidence, and Risk Factors

Set 1: Disease Prevalence and Incidence

1. Population with a Stable Age Distribution:

How can the prevalence of a disease decrease despite a constant incidence rate?

Prevalence is a function of the incidence rate and the average duration of the disease. If the incidence rate is constant, a decrease in the average disease duration can cause prevalence to decrease. This can happen due to improved treatment (leading to quicker cures) or if the disease becomes more rapidly fatal.

2. Evaluating Preventive

Endometrial Cancer: Natural History, Diagnosis, and Treatment

Endometrial Cancer: Natural History

ITEM 17: Natural History of ENDOMETRIAL CANCER

Endometrial cancer, limited to the uterus, may not involve lymph node metastasis (LN). When diagnosing, consider that local growth originates without uterine mucosa involvement and may extend in two main ways:

  • Extension into the uterus
  • Extension into the myometrium

Pathological Classification

The vast majority of endometrial cancers are adenocarcinomas, including:

  • Endometrioid
  • Serous papillary
  • Mucinous
  • Clear cell
  • Mixed cell

Understanding Shingles: Symptoms, and Treatment

Zoster (Herpes Zoster, Shingles)

Definition, Epidemiology, Pathogenesis, Clinical Features, Complications, Differential Diagnosis, Treatment

Definition

Segmental (dermatomal) painful skin disease caused by reactivation of Varicella-Zoster Virus (VZV).

Epidemiology

Approximately 10–20% of seropositive adults develop clinically apparent zoster. The peak incidence is between 50–70 years of age. In younger patients, consider HIV and iatrogenic immunosuppression.

Pathogenesis

Following the initial varicella

Brain Anatomy and Function

Understanding the Human Brain and Nervous System

The brain is the control center for the entire nervous system. It can be divided into three main sections: the cerebrum, the cerebellum, and the brain stem.

The Cerebrum

The cerebrum is divided into two halves, called hemispheres, which are connected by bundles of nerves. The cerebrum controls all conscious activities, intelligence, memory, language, skeletal muscle movements, and senses.

The outer surface of the cerebrum, called the cerebral cortex,
