Understanding BPH and Overactive Bladder (OAB)

Pathophysiology of Benign Prostatic Hyperplasia (BPH)

Benign Prostatic Hyperplasia (BPH) is characterized by non-malignant prostate growth, which leads to Bladder Outlet Obstruction (BOO) and subsequent detrusor hypertrophy. The body's compensatory changes include increased voiding pressure, incomplete bladder emptying, and urinary stasis. BOO disrupts afferent signaling, which can cause neurogenic detrusor overactivity. Furthermore, chronic obstruction can lead to myogenic bladder dysfunction due to altered smooth muscle excitability.

Epidemiology and Demographics

BPH is more common in older patients, particularly those over 75. There are also notable racial differences:

• Black men often have a higher

Pharmacology Fundamentals

Pharmacokinetics: What the Body Does to the Drug

Phases:

1. Absorption – How a drug enters the bloodstream

2. Distribution – How a drug travels through the body

3. Metabolism – How a drug is broken down (mainly in the liver)

4. Excretion – How a drug leaves the body (mainly through the kidneys)

🧠 Memory Trick: ADME — Absorb, Deliver, Metabolize, Exit

Pharmacodynamics: What the Drug Does to the Body

• Describes how a drug works at the target site

• Involves receptor binding, enzyme interactions, and therapeutic vs. side effects

Examples:

• Beta blockers bind to beta receptors → slow heart rate

• Insulin binds to insulin receptors → lowers blood sugar

Drug Release Types: ER, IR, SR, XL, CR

Flabby Etiology and Treatment

Etiology of Flabby Tissue:

1. Old, loose dentures.
2. Anterior interference determining Vertical Dimension of Occlusion (VDO).
3. Rapid ridge resorption leading to a knife-edge ridge.
4. Complete maxillary denture opposing natural mandibular teeth.
5. Loose, ill-fitting dentures.
6. Dentures with anterior porcelain teeth and posterior resin teeth.
7. Over-eruption of opposing natural teeth.
8. Failure to remove dentures at night.
9. Overextended denture border causing epulis fissuratum.

Treatment for Flabby Tissue:

A) Removal of Cause:

• Remove pressure areas.
• Relining old dentures with soft tissue conditioning.
• Correction of occlusal disharmonies.
• Restoration of lost VDO.

B) Remove Denture: (For acute inflammation).

C) Recovery Program:

1. Massage soft tissues.

Diabetes Mellitus Essentials

• Type 1: Autoimmune, insulin-dependent, early onset.
• Type 2: Insulin resistance, gradual onset, linked to diet/weight.
• Diagnosis: Fasting glucose >126 mg/dL, HbA1c.
• Metformin: Hold before contrast dye; risk of lactic acidosis.

Hypoglycemia vs. Hyperglycemia

• Hypoglycemia (<70 mg/dL): Shaky, sweaty, confused, hungry.
• Hyperglycemia: Headache, nausea, fruity breath.
• Treatment: Juice/glucose if conscious; glucagon or D50 if unconscious.

Insulin Types and Administration

• Rapid-acting (Lispro): Onset 10–15 min, eat immediately after injection.
• Short-acting (Regular): Onset 30–60 min.
• Intermediate-acting (NPH): Peak 4–12 hr (cloudy appearance).
• Long-acting (Glargine): No peak, lasts 24 hr.
• Mixing Insulin: Clear (Regular) before
