Lung Cancer Classification and Characteristics

Small Cell Lung Cancer (SCLC)

• Usually originates in a central location.
• High risk of lymph node metastases.
• Most patients present with metastases at diagnosis.

Non-Small Cell Lung Carcinoma (NSCLC)

• Adenocarcinoma

  • Usually peripheral.
  • More frequent in nonsmokers and women.
  • High risk of lymph node invasion and distant metastases.

• Squamous Cell Carcinoma

  • The most common of all lung cancers.
  • Normally affects the bronchi.
  • High risk of nodal involvement.

• Large Cell Carcinoma

Other Lung Tumors

• Carcinoid Tumors

Oncological Treatment for Lung Cancer

Treatment for Stages I and II Lung Cancer

Surgical Treatment (Surgery)

• Lobectomy: Excision of the lobe containing the tumor.
• Pneumonectomy: Full excision of the lung. Performed if

Foundations of Health and Well-being

Defining Health

Health encompasses social, cultural, economic, and biological factors, leading to continuous change.

The World Health Organization (WHO) states that health is a complete state of physical, mental, and social well-being, not merely the absence of disease, plus the ability to function.

Levels of Health and Well-being

Achieving a perfect state of health involves optimal physical and mental well-being, leading to a perfect state of welfare.

Primary Health Care (PHC) is defined as essential assistance that should be generally available to all individuals and families in the community, through appropriate means accessible to them.

Fetal Development: The Journey to Birth

First Trimester Milestones (Weeks 8–11)

By 8 weeks, the embryo transitions into a fetus.

Week 9: Nervous System and Movement

• The nervous system generates neurons.
• The fetus begins to tremble, strengthening muscles through involuntary spasms.
• The brain does not yet control the heartbeat.

Week 11: Reflexes and Growth Spurt

• The kicking reflex begins (the fetus starts experimenting with its feet).
• The period from Week 6 to 11 shows the most notable growth.

Second Trimester Development (Up to Week 18)

The fetus develops strong muscles and bones, connecting all organs of the nervous system. It gains total control of the brain and becomes sensitive to touch. The fetus is aware of its space and performs countless movements.... Continue reading "Fetal Development Timeline: From Embryo to Newborn Senses" »

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

Measles Protection: Vaccination and Natural Immunity

A concerned aunt has two children: one 8 years old and another 1 year and 8 months old. The younger child has contracted measles. The aunt is particularly worried about her 8-year-old, fearing that contracting measles at that age could lead to sterility. She asks why the doctor assured her that her 8-year-old son was already protected.

Explanation of Protection:

• Vaccine-Acquired Immunity: The 8-year-old child is likely protected because, at 12 months of age, children typically receive the Measles, Mumps, and Rubella (MMR) vaccine. This is a preventive vaccine that provides acquired immunity through the introduction of an external agent (the vaccine).
• Natural Immunity from Prior Illness: Another

Welcome to Redheads United

Redheads United is an organization for redheads who believe that anti-redhead behavior, or Reddism, must come to an end. We refuse to accept that redhead jokes are something we should simply endure. We firmly believe that Reddism is no better than racism, and we advocate for redheads to be recognized as a minority group in the UK, in the same way as ethnic and religious minorities.

You've also shared your feelings about having red hair, and we're here to amplify those voices.

Phonemes and Distinctive Phonological Features

Phonemes: abstract units in the sound system of a language. A phoneme is the mental image that speakers have; each time a phoneme is realized in speech it may have a different physical sound but changes in phonemes can alter the meaning of a word. Phonemes are typically represented between slashes, e.g., /p/ or /a/.

Sound (phonetic realization): the practical articulation of a phoneme — the actual acoustic and articulatory realization in speech.

Phonetics: the physical science that studies the linguistic articulation of each human speech sound and its acoustic characteristics.

Letter: visual symbols through which phonemes are expressed in written form.

Diphthongs: the union of two vowel phonemes within... Continue reading "Phonemes, Vowels, Consonants and Distinctive Features" »

Breast Cancer Screening Programs

Screening typically involves mammography, often starting around age 50, with the goal of detecting emerging cancer (Ca).

• Sensitivity: > 85%
• Specificity: > 90%

Early Detection Recommendations

Monthly breast self-examination (BSE) is generally not recommended due to potential issues:

• Causes anxiety.
• High rate of false positives (FP+).
• May lead to unnecessary biopsies and expense.

Recommendations by Age Group

• Women 35–40 years: Annual clinical breast examination and bilateral mammography (only if clinically indicated).
• Women over 40 years: Annual clinical breast examination and mammography every 1–2 years.

Clinical Presentation and Diagnosis

Clinical diagnosis typically follows two pathways:

1. Asymptomatic Women: Suspicious
