Medical Finals & OSCEs Notes

Approximately 119 pages

This is my collection of typed notes and diagrams made for my Finals in Medicine, both the written exams and the Objective Structured Clinical Examinations, OSCEs, which we all dread. I found that making not only academic notes, but also notes of practical use for the OSCEs was very valuable.

This pack includes OSCE notes of clinical examination walkthroughs and clinical signs, examination interpretation, presentation and summaries for various OSCE subjects, as well as chest x-ray Interpretati...

The following is a more accessible plain text extract of the PDF sample above, taken from our Medical Finals & OSCEs Notes. Due to the challenges of extracting text from PDFs, it will have odd formatting:

Cancer and Histology

Adenocarcinoma=neoplasia of epithelial tissue of glandular origin

Carcinoma=neoplasia of epithelial tissue

Carcinoma-in-situ=neoplasia of epithelial tissue that has not (yet) eroded through the basement membrane

Squamous cell carcinoma=neoplasia of epithelial tissue of squamous cells

Sarcoma=cancer of connective tissue

Cancer Histological classification/Cell type
Pancreatic Ductal adenocarcinoma
Pancreatic (MEN1) Insulinoma, gastrinoma, glucagonoma, non-functioning
Breast
  • Non-invasive ductal carcinoma-in-situ (premalignant)

  • Non-invasive lobular carcinoma-in-situ (premalignant)

  • Invasive ductal carcinoma (70% of all breast cancers)

  • Invasive lobular carcinoma

  • Medullary carcinoma

  • Colloid cancer

  • Tubular cancer

  • Cystadenocarcinoma

Paget’s disease of the breast Thought to be ductal carcinoma-in-situ
Kidney Clear cell carcinoma/renal cell carcinoma (vHL)
Kidney in sickle cell trait Renal medullary carcinoma
Bladder Urothelial cell carcinoma/transitional cell carcinoma
Bladder (schistosomiasis) Squamous cell carcinoma
Prostate Adenocarcinoma
Prostatic intraepithelial neoplasia/PIN Premalignant carcinoma-in-situ that develops into prostatic adenocarcinoma
Thyroid

Commonest: papillary thyroid cancer

Second commonest: follicular thyroid cancer

Thyroid (MEN2A/B)(NF1) Medullary thyroid cancer
Parathyroid Parathyroid carcinoma (seen in MEN1) (much less common than benign parathyroid adenoma)
Small cell lung cancer/SCLC

Oat cell carcinoma; derived from APUD cells

(20% of all lung cancers)

Non-small cell lung cancer/NSCLC

Many:

  • Squamous cell carcinoma (20% of all lung cancers)

  • Adenocarcinoma (40% of all lung cancers)

  • Large cell carcinomas

  • Adenosquamous carcinomas

Mesothelioma Derived from mesothelium
Colorectal/CRC Adenocarcinoma
Gastric Adenocarcinoma
Oesophageal

Upper two-thirds=squamous cell carcinoma

Lower third=adenocarcinoma (from GORD and Barrett’s oesophagus)

Laryngeal Squamous cell carcinoma
Liver Hepatocellular carcinoma
Gall bladder Adenocarcinoma
Basal cell carcinoma/BCC ‘Rodent ulcers’ from keratinocytes in the epidermis
Melanoma Epidermal malignancy of melanocytes
Squamous cell carcinoma/SCC Neoplasia of keratinocytes in the epidermis that destroys the dermoepidermal junction and invades down into the dermis
Bile duct Cholangiocarcinoma
Bowen’s disease/SCC-in-situ Premalignant SCC confined to the epidermis
Epithelial cells of vessel walls Angiosarcoma
Lymphoma B or T cell lymphocytes
Lymphocytic leukaemia Marrow cell precursors of lymphocytes
Myeloid leukaemia Marrow cell precursors of myeloid cells (RBCs, platelets, granulocytes)
Cholesteatoma Not actually cancer; a destructive growth of keratinising epithelial cells of the middle ear
Testicular

95% are germ cell cancers:...
