Autopsy Method

Scissors: Between the thumb and the index finger, the heart is cut. External review, there are gutting and joint dissection.

External Review

External review involves the inspection and palpation of the body from head to toe. The pathologist and the technician must assist in mobilizing the body, annotating data in the autopsy report, and having the necessary equipment for the collection of samples. The pathologist will be placed on the right of the body and the technician on the left.

Check:

• Signs of death: Stiffness, lividities, putrefaction.
• External Review: Sex, age, height, weight, and head circumference (in children), muscle development, color, skin changes and hair distribution, natural orifices and external genitalia, palpable

Intervention in Language Problems

This relates to patients with difficulties in language acquisition, verbal expression, pronunciation, reading, and writing. The speech therapist's role is to teach effective communication strategies and provide systems that enable individuals to express themselves through spoken, written, or gestural means.

Speech Therapy

Speech therapy is a discipline encompassing the study, prevention, assessment, diagnosis, and treatment of language pathologies.

Speech Articulation Disorders

• Dyslalia: Difficulty articulating phonemes (vowels and consonants) correctly.
  • Evolutionary: Language immaturity.
  • Audiogenic: Hearing impairment.
  • Functional: Difficulty controlling speech organs.
  • Organic: Organ impairment.
• Diglossia: Changes in

Esophagus: Symptoms and Conditions

The following symptoms are commonly associated with esophageal disorders:

• Dysphagia: Difficulty swallowing, often described as a retrosternal sensation of bolus detention.
• Odynophagia: Painful swallowing.
• Regurgitation: The return-to-mouth of food originating from the esophagus.
• Sialorrhea: Excessive production and flow of saliva.
• Heartburn (Pyrosis): A burning sensation caused by the reflux of gastric contents.
• Aerophagia: The sudden evacuation of swallowed air.
• Esophagorrhagia: Expulsion of blood via vomiting (hematemesis).

Major Esophageal Conditions

Megaesophagus or Achalasia

Diffuse dilation of the esophageal wall, characterized by internal dysphagia. It presents as permanent retrosternal or interscapular odynophagia,...

Acute Hepatitis: An Overview

Acute hepatitis is a necroinflammatory liver disease caused by infection from hepatitis viruses A, B, C, D, and E. The key difference between acute and chronic hepatitis is the duration, with the distinction typically made at 6 months.

Hepatitis A

Hepatitis A is caused by an RNA virus. Transmission is typically fecal-oral and can, in rare cases, be fatal, leading to fulminant hepatitis.

Epidemiology

Hepatitis A often occurs in cycles every 5 to 10 years, with seasonal predominance in childhood. The infection spreads through the fecal-oral route, often via contaminated food and water. Parenteral transmission is rare.

Symptoms

Symptoms include coluria (dark urine) followed by scleral icterus (jaundice) and hypocholia (pale...

The Role of School Dining in Education

School dining serves as an essential educational service. In developed countries, these programs have evolved to become sociocultural spaces that help children build healthy habits from their first days of life. This process begins within the family, continues through high school, and is enriched by the school dining experience, which strengthens the link between parents and educators. Consequently, healthy eating habits are now a core objective of the school curriculum.

Key Components of a School Dining Project

For a school dining program to function effectively, it must be integrated into the school's broader educational project, incorporating the following points:

• Professional Coordination: Alignment regarding

Understanding Food Additives

Additives are substances used to prolong the shelf life of food, prevent microbiological contamination, and enhance flavor, texture, and color. They are strictly regulated by the FAO and WHO, and in Europe, by the Scientific Committee for Food.

Types of Food Additives

• Colors (E1...): Natural and artificial substances that provide color to food; some may cause allergic reactions.
• Preservatives (E2...): Prevent the growth of bacteria, fungi, and yeasts. Examples include sorbic acid (jams/yoghurts), sulfur acid (wine fermentation), and nitrates/nitrites (meat products to prevent botulism). Some, like benzoic acid, can be allergenic.
• Antioxidants (E3...): Prevent fat rancidity. These include tocopherols and vitamin E, though

Hyperaldosteronism

Concept:

A disorder of the adrenal gland that releases large amounts of aldosterone into the bloodstream.

Types:

• Primary Hyperaldosteronism: Overproduction of aldosterone by a disorder of the adrenal gland.
• Secondary Hyperaldosteronism: An increase in aldosterone and renin due to activation of the renin-angiotensin system.

Etiology:

Primary Hyperaldosteronism:

• Adrenal adenoma (Conn's Syndrome)
• Bilateral adrenal hyperplasia
• Unilateral adrenal hyperplasia
• Adrenal carcinoma

Secondary Hyperaldosteronism:

• Increased production of renin by the kidney
• Hypersecretion of renin (e.g., Bartter's Syndrome)

Epidemiology:

Primarily affects women between 30-50 years of age.

Clinical Manifestations:

• Hypertension
• Hypernatremia (increased sodium)
• Hypokalemia (

Premature Ejaculation (PE) Management

Dapoxetine (Priligy)

Dapoxetine is a selective serotonin reuptake inhibitor (SSRI) that modulates the ejaculatory reflex.

• Dose: 30 mg, taken 1–3 hours before anticipated intercourse.
• Maximum Frequency: One dose per 24 hours.

Side Effects

• Dizziness
• Vomiting
• Fainting (Syncope)
• Hypotension

Contraindications

• Significant cardiac conditions.
• Hepatic impairment.
