Microcytic Hypochromic Anemia

1. Iron Deficiency Anemia

Causes

• Physiological: Nutritional deficiency, menstrual iron loss, pregnancy, blood donation, gastrointestinal bleeding.
• Pathological: Excessive blood loss (peptic ulcers, carcinoma), excessive uterine bleeding.

Clinical Features

• Fatigue, pale oral mucosa/lips/eyes, koilonychia, sparse hair.

Oral Manifestations

• Glossitis, stomatitis, angular cheilitis, oral candidiasis, aphthous ulcers.
• Treatment: Ferrous sulfate, eliminate underlying cause.

2. Thalassemia

Also known as Cooley's anemia. Features include kyphosis, dark urine, and jaundice.

Oral Manifestations

• Spiky short roots, taurodontism, enlarged bone marrow, parotid gland swelling (iron deposition), caries.
• Treatment: Deferoxamine mesylate, RBC

Classification and Therapeutic Uses of NSAIDs

Classification of NSAIDs

NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) are classified based on their chemical structure or COX (cyclooxygenase) enzyme selectivity.

I. Classification by COX Selectivity

1. Non-selective COX Inhibitors

These inhibit both COX-1 and COX-2 enzymes:

• Aspirin (acetylsalicylic acid)
• Ibuprofen
• Naproxen
• Indomethacin
• Ketorolac
• Diclofenac
• Piroxicam

2. Preferential COX-2 Inhibitors

These selectively inhibit COX-2 more than COX-1, but not exclusively:

• Meloxicam
• Nabumetone
• Etodolac

3. Selective COX-2 Inhibitors (Coxibs)

These minimally affect COX-1, resulting in lower GI side effects:

• Celecoxib
• Etoricoxib
• Parecoxib
• Valdecoxib (withdrawn in some countries due to cardiovascular risk)
• Rofecoxib (withdrawn

Maxillofacial Defects: Classification

Congenital Defects

• Cleft lip and palate
• Microtia and Anotia
• Congenital anophthalmia

Acquired Defects

• Surgical resection
• Trauma
• Pathological: Osteomyelitis, post-radiation necrosis

Developmental Defects

• Micrognathia
• Maxillary hypoplasia
• Hemifacial microsomia

Objectives of Maxillofacial Restoration

• Restoration of function
• Restoration of esthetics
• Psychological rehabilitation
• Surgical reconstruction

Rehabilitation of Maxillofacial Defects

• Surgical reconstruction
• Prosthetic rehabilitation
• Combined surgical and prosthetic approach

Palatal Development

• Primary Palate: 5th week, median nasal process rises to form the premaxilla.
• Secondary Palate: 7th week, fusion begins at the nasal septum, giving rise to the hard and soft palate.

Medical Prescription Components and Units

A medical prescription includes the date, patient identification (such as name, age, and weight if relevant), the Rx symbol (meaning "take"), the inscription (drug name, strength, dosage form, and quantity), the subscription (instructions to the pharmacist), the signatura or "Sig." (directions for the patient including route, frequency, and duration), the prescriber's information (name, signature, license number), and refill instructions. Units of measurement include micrograms (µg), milligrams (mg), grams (g), milliliters (mL), liters (L), concentrations such as percentage (%) and mg/mL, international units (IU), and sometimes weight per kilogram of body weight. Obsolete units... Continue reading "Pharmacology Essentials: Drug Forms, Actions, and Therapeutic Classes" »

I. Foundations

Epidemiology: The study of the distribution (who, where, when) and determinants (why, how) of health and disease in populations.

• Goal: Reduce morbidity and mortality through prevention.
• Scientific Method: Observation → Hypothesis → Test → Conclusion → Action.

Key Definitions:

• Distribution: Frequency and pattern of health events by person, place, and time.
• Determinants: Causes, risk factors, or exposures that affect health outcomes.
• Population: The group under study.
• Prevention: Primary (prevent onset), Secondary (early detection), Tertiary (reduce disability).

II. Measures of Disease Frequency

Asthma Management Case Study

Patient: Michael Adams, 55-year-old male.

History: Diagnosed with asthma in early adulthood. No other relevant medical conditions or drug allergies. Uses a salbutamol inhaler as needed and a preventer inhaler twice daily.

Emergency Presentation

Admitted to A&E on Thursday afternoon following increasing shortness of breath and wheezing while cleaning his garage. Symptoms included chest tightness, wheezing, and anxiety.

Clinical Assessment

• SpO₂: 89% on room air
• RR: 28 bpm
• BP: 140/85 mmHg
