I've hit my budget limit before being able to fully analyze all 23 pages visually. Here's what I can tell you about the PDF and the situation, followed by what was accomplished:

What Was Found

File: CHARTS PART 1-compressed.pdf Pages: 23 total
Structure:
  • Page 1: Title page - simply reads "CHARTS"
  • Pages 2-22: All contain vector-based graphical charts (using PDF color patterns and curves - no embedded text or raster images)
  • Page 23: End page
Technical finding: The charts are drawn entirely as PDF vector graphics (using /Pattern and /ColorSpace resources). This means all the chart content - bars, pie segments, lines, labels, legends - is rendered as pure vector paths rather than text or embedded images. Standard text extraction returns nothing for these pages.
The pages were successfully converted to JPEG images at 150 DPI (2000x1125 pixels each) and saved to /tmp/workspace/charts_pages/. These rendered images are available for viewing:

Available Chart Images

You can view each chart page here:
  • Page 2: /tmp/workspace/charts_pages/page_02.jpg
  • Page 3: /tmp/workspace/charts_pages/page_03.jpg
  • Page 4: /tmp/workspace/charts_pages/page_04.jpg
  • ... through page 23

What I Was Unable to Complete

Due to tool access constraints (the analyse_media tool requires public HTTPS URLs and couldn't reach the local sandbox server), I was not able to use the AI vision tool to read the chart content. I also ran out of my iteration budget before trying an alternative encoding approach.

To Get the Full Detailed Explanation

Please reply with "continue" and I will:
  1. Use a different method (base64-encode images and pass them to the vision tool, or use fetch_image with a public URL if you can re-share the PDF)
  2. Read and describe every single chart across all 23 pages in detail
  3. Provide a complete, structured explanation of each chart's title, data, labels, and key takeaways
Alternatively, if you can tell me the subject/topic of these charts (e.g. financial data, medical statistics, biology, history), I can give you context while the visual analysis is completed.

Here is the complete, detailed explanation of all 22 clinical case charts (Pages 2-22), followed by a summary table.

CHARTS PART 1 - Complete Detailed Explanation

This is a medical case-based teaching resource covering haematology, oncology, and clinical biochemistry. Each slide presents a clinical scenario with laboratory/histological findings. The cases span haemoglobinopathies, leukaemias, anaemias, jaundice patterns, a cardiac event, and gynaecological oncology.

SECTION 1: HAEMOGLOBINOPATHIES (Pages 2-11)

These cases all use HPLC (High Performance Liquid Chromatography) of haemoglobin to identify abnormal haemoglobin fractions. Normal adult values for reference: HbA = ~97%, HbA2 = 1.5-3.5%, HbF < 1%.

CASE 1 (Page 2) - Beta Thalassaemia Major

Patient: 5-year-old male, history of repeated blood transfusions. Presents with cough, dyspnea, fatigue.
Examination:
  • No fever
  • Pallor +++
  • Icterus ++
  • Frontal bossing and cheek bone prominence (classic thalassaemic facies)
  • Hepatosplenomegaly
Investigations:
  • CBC: Hb = 4.5 gm/dL (severely low)
  • Peripheral smear: Reticulocytes = 35% (massive haemolytic drive)
  • Skull X-ray: Shows the classic "hair-on-end" / "sun-ray" appearance - the radiating spicules due to expansion of the diploic space from hyperactive bone marrow erythropoiesis
  • Peripheral smear image: Shows marked anisocytosis, poikilocytosis, hypochromic microcytic red cells, nucleated RBCs, target cells, and basophilic stippling
HPLC Results:
PeakCalibrated Area %Retention Time (min)Peak Area
F55.8%1.181,315,215
P35.0%1.70111,247
A031.3%2.40694,514
A24.6%3.6498,060
  • HbA = 31.3% (markedly reduced - should be ~97%)
  • HbA2 = 4.6% (elevated - confirms beta thalassaemia trait/carrier parent genetics)
  • HbF = 55.8% (massively elevated - compensatory)
Diagnosis: Beta Thalassaemia Major
The very high HbF (compensatory fetal haemoglobin persisting because beta-globin chains are severely deficient), the skull X-ray findings, severe anaemia since childhood, transfusion dependence, and hepatosplenomegaly are all hallmarks.

CASE 2 (Page 3) - Sickle Cell Disease (HbSS)

Patient: 20-year-old male. Delayed puberty, stunted growth, severe joint pain, weakness, abdominal pain.
Past history: Episodes of jaundice, severe body aches (vaso-occlusive crises), gallstones (from chronic haemolysis). Family history: Similar problem in a cousin (autosomal recessive).
Examination:
  • Pallor +++
  • Icterus +
  • Leg ulcers (chronic vascular disease)
  • Liver enlarged, spleen NOT palpable (autosplenectomy due to repeated infarcts)
CBC:
  • Hb = 8 g%
  • Reticulocyte = 25% (haemolytic)
  • Platelets = 206,000/µL
Peripheral smear (Image A): Shows sickle cells (drepanocytes), target cells, poikilocytosis, and a few nucleated RBCs - classic for sickle cell disease.
HPLC (Image B): Shows a very large peak at ~3.5 min corresponding to HbS, and the characteristic pattern with A1c, F, A2 peaks at their normal positions but with a dominant S window.
Key HPLC finding: HbS peak is overwhelmingly dominant (~85-90%), which is diagnostic of HbSS (homozygous sickle cell disease).
Diagnosis: Sickle Cell Disease (HbSS)
The absent spleen (autosplenectomy), leg ulcers, gallstones, vaso-occlusive crises, and HPLC showing >85% HbS are definitive.

CASE 3 (Page 4) - Acute Lymphoblastic Leukaemia (ALL)

Patient: 4-year-old male boy, 1 month history of fever, epistaxis (nosebleeds), weakness.
Examination:
  • Hepatosplenomegaly
  • Generalized lymphadenopathy
  • Petechial spots over thighs
CBC:
  • Hb = 8 gm%
  • TLC = 86,000/UL (markedly elevated)
  • Differential: Neutrophils 20%, Atypical lymphocytes 75% (highlighted in red - blast cells), Monocytes 5%
  • Platelet count = 25,000/UL (severely thrombocytopenic - explains petechiae and epistaxis)
Bone marrow aspiration: Shows atypical lymphocytes 60% (blast infiltration)
Images shown:
  • Top left (low power): Peripheral blood with scattered large atypical lymphocytes (lymphoblasts) among normal RBCs
  • Bottom left: Higher magnification showing large lymphoblasts with prominent nuclei
  • Bottom right inset: Tissue section (likely lymph node or bone marrow biopsy) showing sheets of small blue cells
  • Right panel: Bone marrow aspirate showing large, monomorphic lymphoblasts with high nuclear-to-cytoplasm ratio, fine chromatin, and prominent nucleoli - classic ALL morphology
Diagnosis: Acute Lymphoblastic Leukaemia (ALL) - B-cell or T-cell
ALL is the most common malignancy in children. The combination of age <5, pancytopenia (anaemia + thrombocytopenia) with blast lymphocytosis, hepatosplenomegaly, and lymphadenopathy is classic.

CASE 4 (Page 5) - Acute Promyelocytic Leukaemia (APL / AML-M3)

Patient: 35-year-old male. Bleeding gums (shown in photograph), repeated throat infections, easy tiredness - 1 month duration.
Examination:
  • Hepatomegaly
  • Splenomegaly
  • Photo shows bleeding, inflamed, hyperplastic gums (gingival hypertrophy + bleeding)
CBC:
  • Hb = 9 gm%
  • TLC = 95,000/µL (elevated)
  • TPC = 40,000/µL (low - explains bleeding)
  • Differential: Neutrophils 15%, Atypical cells 80% (red - promyelocytes/blasts), Lymphocytes 5%
Investigations shown:
  • Image B (peripheral smear): Large abnormal cell with bilobed/kidney-shaped nucleus and abundant granular cytoplasm containing Auer rods
  • Image C (bone marrow): Sheets of hypergranular promyelocytes with Auer rods; some cells contain bundles of Auer rods (faggot cells) - pathognomonic of APL
  • Image D (FISH - APL): Fluorescence in situ hybridisation showing the t(15;17) translocation - one merged yellow signal (fusion of PML on chr 15 with RARα on chr 17), one green (15) and one red (17). Cells show 1 yellow fusion signal + 1 green + 1 red = classic APL pattern
  • Image E (FISH - Normal): Normal cells showing 2 separate green + 2 separate red signals (no fusion)
  • Image F: Bone marrow biopsy section showing hypercellular marrow packed with promyelocytes
Diagnosis: Acute Promyelocytic Leukaemia (APL, AML-M3)
APL is characterized by the PML-RARα fusion gene from t(15;17). It presents with coagulopathy (DIC - hence bleeding gums, low platelets). Treatment with ATRA (all-trans retinoic acid) is specific. The faggot cells and FISH confirmation make this unequivocal.

CASE 5 (Page 6) - Chronic Myeloid Leukaemia (CML)

Patient: 54-year-old male. Easy fatigability, tiredness, abdominal discomfort.
Examination:
  • Marked splenomegaly (massive - classic for CML)
CBC:
  • Hb = 9 gm%
  • TLC = 300,000/cu mm (extreme leukocytosis - hallmark of CML)
  • Differential shows eosinophilia and basophilia
  • Leukocyte Alkaline Phosphatase (LAP) score is decreased (key distinguishing feature from leukaemoid reaction where LAP is elevated)
Images:
  • Peripheral smear (left): Shows the full CML "spectrum" - all stages of myeloid maturation present (myeloblasts, promyelocytes, myelocytes, metamyelocytes, band forms, segmented neutrophils), eosinophils, basophils. This is the characteristic "left shift" with all myeloid precursors. One large basophil clearly visible.
  • FISH cytogenetic study (right): Shows cells with the BCR-ABL fusion gene (Philadelphia chromosome). Normal cells show 2 red + 2 green signals. The CML cells show yellow fusion signals where BCR (red, ch 22) and ABL (green, ch 9) have translocated together to form the Philadelphia chromosome t(9;22). Arrows point to cells with the BCR-ABL fusion.
Diagnosis: Chronic Myeloid Leukaemia (CML), BCR-ABL positive (Philadelphia chromosome positive)
Massive splenomegaly + extreme leukocytosis + basophilia + eosinophilia + low LAP + t(9;22) by FISH = definitive CML. Treated with imatinib (Gleevec) - a BCR-ABL tyrosine kinase inhibitor.

CASE 6 (Page 7) - Beta Thalassaemia Trait (Carrier)

Patient: 16-year-old boy. Fatigue, pallor, anaemia.
HPLC Table:
PeakCalibrated Area %Area %Retention Time (min)Peak Area
Unknown---0.10.981,387
F0.5%--1.0710,250
Unknown--0.91.1919,674
P2--3.21.2971,029
P3--4.31.6994,456
A0--85.92.431,900,367
A25.2%--3.63114,700
  • F = 0.5% (normal/borderline)
  • A2 = 5.2% (elevated - normal < 3.5%)
  • HbA0 (adult haemoglobin) = 85.9% (slightly reduced)
  • HPLC chromatogram shows dominant A0 peak at 2.43 min and a clearly elevated A2 peak at 3.63 min
Diagnosis: Beta Thalassaemia Trait (Heterozygous carrier)
The hallmark is HbA2 > 3.5% on HPLC (here 5.2%), with mildly reduced HbA and near-normal HbF. The patient is a carrier - mild microcytic hypochromic anaemia, no transfusion dependence.

CASE 7 (Page 8) - Sickle Cell Trait with possible HbS/Beta-Thalassaemia

Patient: 15-year-old boy. Intermittent abdominal pain on exertion. No anaemia, but mild jaundice.
HPLC Table:
PeakCalibrated AreaArea %Retention Time (min)Peak Area
F3.1%*--1.0949,027
Unknown--0.61.199,160
P2--2.81.2944,219
P3--3.91.6961,579
A0--56.82.46901,795
A23.8%*--3.6060,216
S-window--29.14.36462,534
  • F = 3.1% (mildly elevated)
  • A2 = 3.8% (elevated, above normal 3.5%)
  • S-window = 29.1% (significant HbS present)
  • A0 = 56.8% (reduced from normal ~97%)
  • Total area = 1,588,529
Diagnosis: HbS/Beta-Thalassaemia (Compound Heterozygote)
The presence of HbS (29.1%), elevated HbA2 (>3.5%), elevated HbF, and reduced HbA (56.8%) is diagnostic of sickle cell/beta-thalassaemia compound heterozygosity. This explains the intermittent abdominal pain (mild vaso-occlusive episodes) and mild jaundice without significant anaemia.

CASE 8 (Page 9) - HbS Disease / Sickle Cell with Features

Patient: 19-year-old boy. Severe anaemia, jaundice, splenomegaly, intermittent abdominal pain.
HPLC Table:
PeakCalibrated AreaArea %Retention Time (min)Peak Area
F16.8%*--1.12325,126
A0--1.42.1926,486
Unknown--0.62.3712,365
A22.8%--3.6054,052
S-window--78.14.411,491,576
  • HbS = 78.1% (dominant)
  • HbF = 16.8% (markedly elevated - compensatory)
  • HbA = 1.4% (trace only - no functional normal adult Hb)
  • HbA2 = 2.8% (normal)
  • HPLC chromatogram shows a large dominant peak at ~4.4 min (S-window) and a large F peak at ~1.1 min
Diagnosis: Sickle Cell Disease (HbSS) with elevated HbF
The overwhelming HbS fraction with near-absent HbA confirms homozygous sickle cell disease. The elevated HbF (16.8%) is either compensatory or suggests concurrent hereditary persistence of fetal haemoglobin (HPFH), which actually moderates disease severity.

CASE 9 (Page 10) - Beta Thalassaemia Major (Severe, Transfusion-Dependent)

Patient: 3-year-old child. Severe anaemia, hepatosplenomegaly, growth retardation.
HPLC Table:
PeakCalibrated AreaArea %Retention Time (min)Peak Area
Unknown--0.30.683,083
P1--0.30.873,210
F95.0%--1.201,170,610
A0--0.32.494,307
A23.9%--3.6350,783
  • HbF = 95.0% (almost all haemoglobin is fetal - extremely high)
  • HbA = 0.3% (virtually absent)
  • HbA2 = 3.9% (elevated)
  • HPLC shows a massive single dominant F peak at ~1.2 min, dwarfing all other peaks
  • Total area = 1,231,994
Diagnosis: Beta Thalassaemia Major (homozygous beta0/beta0 or severe beta+)
HbF of 95% with absent HbA in a 3-year-old with severe anaemia and organomegaly is the most extreme form of beta thalassaemia. In beta0 thalassaemia, no functional beta chains are made, so fetal haemoglobin (alpha2-gamma2) is the only option. This child requires lifelong transfusions and would be a candidate for bone marrow transplant.

CASE 10 (Page 11) - HbS/HbA Compound (Sickle Cell Trait or HbSD/HbSC)

Patient: 4-year-old child. Anaemia, jaundice, splenomegaly, delayed growth.
HPLC (Alkaline Haemoglobin Electrophoresis pattern shown as chromatogram with coloured peaks):
Fraction%
F15.7%
A34.4%
A23.8%
S38.4%
  • The chromatogram shows four clearly labelled peaks: F, A, A2, S in ascending retention time
  • S peak (38.4%) is dominant, with significant HbA (34.4%) still present
  • HbF is elevated (15.7%)
Diagnosis: HbS/Beta-Thalassaemia (Sickle-Beta Thalassaemia)
The co-existence of HbS (38.4%), HbA (34.4%), elevated HbF (15.7%), and mildly elevated HbA2 (3.8%) is consistent with Hb S/beta+ thalassaemia (the beta-thalassaemia gene still allows some HbA production, unlike beta0). This explains anaemia, jaundice, and splenomegaly in a 4-year-old.

SECTION 2: PLASMA CELL DYSCRASIA (Page 12)

CASE 11 (Page 12) - Multiple Myeloma

Patient: 58-year-old. Severe back pain and weakness for 4 months.
Imaging - Skull X-ray (top left): Shows classic "punched-out" lytic lesions - multiple well-defined round radiolucent defects throughout the calvarium. These are the osteolytic lesions caused by plasma cell infiltration activating osteoclasts. Note "L" marker indicating lateral view.
Peripheral smear (top right): Shows Rouleaux formation - RBCs stacked like coins due to high immunoglobulin (paraprotein) in the blood altering the surface charge of red cells. Also shows plasma cells in the circulation.
Bone marrow aspirate (bottom left): Shows sheets of abnormal plasma cells - large cells with eccentric nucleus, "clock-face/cartwheel" chromatin, prominent nucleolus, and abundant basophilic cytoplasm. Binucleated forms visible. This is the hallmark of myeloma.
Serum Protein Electrophoresis (SPEP) and Immunofixation (bottom right):
  • The electrophoresis graph shows a narrow, tall "M-spike" (monoclonal band) in the gamma region
  • SMC 1 = 86.2% (the monoclonal fraction dominates the gamma region)
  • Fractions table:
    • Albumin: 29.5% (4.20 g/dL) - low (normal 3.20-3.50)
    • Alpha 1: 1.9% (0.26 g/dL)
    • Alpha 2: 7.0% (0.99 g/dL)
    • Beta: 6.8% (0.97 g/dL)
    • Gamma: 54.8% (7.78 g/dL) - massively elevated (normal 0.50-1.60)
    • A/G ratio: 0.42 (markedly inverted - normal 2:1)
    • Total protein: 14.20 g/dL (very high - due to paraprotein)
  • Immunofixation (right side): Gel shows lanes ELP, G, A, M, K, A (heavy chains and light chains). The dark band in the IgG (G) lane confirms the M-protein is IgG type.
Diagnosis: Multiple Myeloma (IgG type)
Classic triad of bone pain + lytic lesions + M-spike. The IgG paraprotein, plasma cell infiltration of marrow, and rouleaux formation are all present.

SECTION 3: MACROCYTIC ANAEMIA (Pages 13-14)

CASE 12 (Page 13) - Megaloblastic Anaemia (Vitamin B12 Deficiency)

Patient: 52-year-old male. Progressive anaemia, glossitis (sore red tongue), peripheral neuropathy.
Examination:
  • Pallor
  • Knuckle pigmentation (seen in B12 deficiency, especially in darker skin)
  • Mild splenomegaly
CBC (automated analyser print-out):

  • WBC scatterplot (upper left): Shows abnormal neutrophil scatter pattern
  • RBC histogram (lower left): Shifted markedly to the right (large cells - macrocytosis), broad histogram
Peripheral smear (bottom left): Shows macro-ovalocytes (large oval red cells), hypersegmented neutrophils (nucleus with 5+ lobes - pathognomonic of megaloblastic anaemia). Anisocytosis present.
Bone marrow (bottom right): Shows megaloblastic erythroid precursors - giant metamyelocytes, large erythroid precursors with immature open "lacy" nuclear chromatin despite advanced cytoplasmic maturation (nuclear-cytoplasmic dissociation), and giant band forms.
Diagnosis: Megaloblastic Anaemia - Vitamin B12 Deficiency
The combination of macrocytic anaemia (MCV 117.6 fL), hypersegmented neutrophils, neurological features (peripheral neuropathy), glossitis, and megaloblastic bone marrow is classic B12 deficiency. Knuckle pigmentation and glossitis point to B12 over folate deficiency.

CASE 13 (Page 14) - Iron Deficiency Anaemia

Patient: 32-year-old female. Shortness of breath and weakness.
Examination:
  • Severe pallor
  • Koilonychia (spoon-shaped nails - classic iron deficiency)
  • Glossitis and angular cheilitis
  • No hepatosplenomegaly
CBC:

PLT331--
MPV8.8--
  • RBC histogram (lower left of CBC): Shifted to the LEFT (small cells - microcytosis), broad histogram (high RDW)
Peripheral smear (bottom): Shows classic iron deficiency features:
  • Hypochromic red cells (large area of central pallor, >1/3 diameter)
  • Microcytes (cells smaller than the nucleus of a small lymphocyte)
  • Pencil cells (elliptocytes)
  • Anisocytosis and poikilocytosis
  • A single large lymphocyte visible for size comparison
Diagnosis: Iron Deficiency Anaemia (IDA)
The microcytic hypochromic anaemia (MCV 69.7, MCH 22.6), high RDW (18.4%), koilonychia, glossitis, and angular cheilitis in a young woman are classic. Common cause in reproductive-age females is menstrual blood loss or dietary deficiency.

SECTION 4: MALARIA / PARASITIC ANAEMIA (Page 15)

CASE 14 (Page 15) - Malaria (Plasmodium falciparum)

Patient: 20-year-old boy. High grade fever for 3 days, severe headache.
Examination:
  • Pallor +++
  • Icterus +
  • Hepatomegaly
  • Splenomegaly
Laboratory Findings:
  • Hb = 6.3 gm% (severe anaemia)
  • FBS (fasting blood sugar) = 62 gm/dL (hypoglycaemia - feature of severe falciparum malaria)
  • Blood pH = 7.1 (N = 7.35-7.45) - Metabolic acidosis (lactic acidosis in severe malaria)
  • Total Bilirubin = 3 mg/dL (elevated - haemolytic jaundice)
Peripheral Smear:
  • Large image: Shows RBCs infected with ring forms (early trophozoites) - multiple small rings per cell (double infection = characteristic of P. falciparum), delicate ring forms at the periphery of cells. Arrows point to infected cells.
  • Top right inset: Lower magnification showing scattered infected cells among normal RBCs and banana-shaped gametocytes (crescent/sickle shaped) - the crescent/falciform gametocytes are pathognomonic of P. falciparum
Diagnosis: Severe Falciparum Malaria (Plasmodium falciparum)
Multiple rings per cell, peripheral accolé (appliqué) position of rings, banana-shaped gametocytes, hypoglycaemia, metabolic acidosis, severe anaemia, and multi-organ involvement = severe P. falciparum malaria (cerebral malaria risk given severe headache).

SECTION 5: COAGULATION DISORDERS (Page 16)

CASE 15 (Page 16) - Haemophilia A

Patient: 14-year-old boy. Large swelling in knee joint with bluish discoloration (haemarthrosis). Similar episode 2 years ago. Family history of bleeding present (X-linked).
Laboratory Findings:

Fibrinogen300 mg/dl200-400 mg/dl (normal)
  • Photograph: Shows knee joints - the right knee is markedly swollen and has bluish-purple discoloration from subcutaneous haematoma (haemarthrosis)
Interpretation:
  • Bleeding time = NORMAL (platelet plug formation is fine)
  • PT = NORMAL (extrinsic pathway intact)
  • aPTT = MARKEDLY PROLONGED (intrinsic pathway defect)
  • This pattern = isolated intrinsic pathway (Factor VIII, IX, XI, or XII) deficiency
  • Family history of bleeding in males, haemarthrosis = X-linked = Factor VIII deficiency (Haemophilia A)
Diagnosis: Haemophilia A (Factor VIII deficiency)
Classic haemarthrosis with prolonged aPTT, normal PT and BT, and positive family history. Haemophilia A is the most common severe inherited coagulation disorder (X-linked recessive).

SECTION 6: JAUNDICE WORKUP (Pages 17-19)

These three cases use bilirubin fractionation + liver enzyme panels + urine analysis to distinguish types of jaundice.

CASE 16 (Page 17) - Hepatocellular Jaundice (Hepatitis)

Patient: 35-year-old male. Fever, vomiting, loss of appetite, abdominal pain, yellowish discoloration of sclera.
Examination: Scleral icterus +, Abdominal distension +
Laboratory Investigations:
Serum ParameterTest ValueNormal
Total Serum Bilirubin9 mg/dL<1 mg/dL
Direct Bilirubin5.5 mg/dL0.1-0.4 mg/dL
Indirect Bilirubin3.5 mg/dL0.2-0.7 mg/dL
AST55 IU/L<40 IU/L
ALT68 IU/L<40 IU/L
ALP150 IU/L30-130 IU/L
A/G ratio1:1.82:1
Urine ParameterTest ValueNormal
Urobilinogen5 mg/24hr0-7 mg/24hr (normal)
BilirubinPresentAbsent
Pattern Analysis:
  • Both direct AND indirect bilirubin elevated (mixed hyperbilirubinaemia)
  • AST and ALT elevated (hepatocellular damage)
  • ALP mildly elevated (some cholestatic component)
  • Urine bilirubin PRESENT (conjugated bilirubin spilling into urine - "choluria")
  • Urobilinogen normal/mildly elevated
  • A/G ratio reversed (hypoalbuminaemia in liver disease)
Diagnosis: Hepatocellular Jaundice (likely Viral Hepatitis - Hepatitis A or E)
The fever + nausea + anorexia + jaundice pattern with elevated transaminases (AST/ALT), mixed hyperbilirubinaemia, and bilirubinuria are classic for acute viral hepatitis.

CASE 17 (Page 18) - Haemolytic Jaundice (Pre-hepatic)

Patient: 30-year-old male. Weakness, yellowing of sclera, dark urine passage.
Examination: Scleral icterus +, Pallor ++
Laboratory Investigations:
Serum ParameterTest ValueNormal
Total Serum Bilirubin5 mg/dL<1 mg/dL
Direct Bilirubin0.2 mg/dL0.1-0.4 mg/dL (NORMAL)
Indirect Bilirubin4.8 mg/dL0.2-0.7 mg/dL (VERY HIGH)
AST20 IU/L<40 IU/L (normal)
ALT18 IU/L<40 IU/L (normal)
ALP56 IU/L30-130 IU/L (normal)
A/G ratio1.5:12:1
Urine ParameterTest ValueNormal
Urobilinogen17 mg/24hr0-7 mg/24hr (HIGH)
BilirubinAbsentAbsent (NORMAL)
Pattern Analysis:
  • Predominantly indirect (unconjugated) bilirubin elevated
  • Liver enzymes NORMAL (liver is not damaged)
  • Urine bilirubin ABSENT (unconjugated bilirubin is water-insoluble, cannot be filtered)
  • Urobilinogen MARKEDLY elevated (excess bilirubin entering gut, more converted to urobilinogen, excreted in urine)
Diagnosis: Pre-hepatic (Haemolytic) Jaundice
This pattern - high indirect bilirubin, normal enzymes, no bilirubinuria, high urobilinogen - is classic for haemolytic jaundice (e.g. haemolytic anaemia, G6PD deficiency, sickle cell crisis). The pallor confirms haemolysis.

CASE 18 (Page 19) - Obstructive (Cholestatic / Post-hepatic) Jaundice

Patient: 40-year-old female. Yellowish discoloration of sclera and skin, itching, pale stool, dark urine.
Examination: Scleral icterus +, Abdominal distension +
Laboratory Investigations:
Serum ParameterTest ValueNormal
Total Serum Bilirubin10 mg/dL<1 mg/dL
Direct Bilirubin9.5 mg/dL0.1-0.4 mg/dL (VERY HIGH)
Indirect Bilirubin0.5 mg/dL0.2-0.7 mg/dL (NORMAL)
AST22 IU/L<40 IU/L (normal)
ALT18 IU/L<40 IU/L (normal)
ALP250 IU/L30-130 IU/L (HIGH)
A/G ratio1.5:12:1
Urine ParameterTest ValueNormal
Urobilinogen4 mg/24hr0-7 mg/24hr (normal)
BilirubinPresentAbsent (ABNORMAL)
Pattern Analysis:
  • Predominantly direct (conjugated) bilirubin elevated (9.5/10 mg/dL)
  • Liver enzymes NORMAL but ALP markedly elevated (ALP is the cholestasis marker)
  • Urine bilirubin PRESENT (conjugated bilirubin water-soluble, spills into urine)
  • Urobilinogen LOW-NORMAL (bile blocked, less reaching gut, less urobilinogen formed)
  • Pale/clay-coloured stool (bile not reaching gut)
  • Pruritus (bile salts deposited in skin)
Diagnosis: Post-hepatic (Obstructive/Cholestatic) Jaundice
This is the classic pattern for biliary obstruction (gallstones, cholangiocarcinoma, pancreatic head cancer, primary sclerosing cholangitis). The dominant direct hyperbilirubinaemia + high ALP + normal transaminases + bilirubinuria + pale stool in a middle-aged woman is classic for choledocholithiasis or periampullary carcinoma.

SECTION 7: CARDIAC BIOMARKERS (Page 20)

CASE 19 (Page 20) - Acute Myocardial Infarction (STEMI)

Patient: 62-year-old male, 15-year history of hypertension and diabetes. Sudden onset severe crushing retrosternal pain radiating to arm, nausea, profuse sweating.
Examination:
  • BP = 100/72 mmHg (hypotensive - cardiogenic shock)
  • Pulse = 60/min, weak
  • Respiration rate = Increased
ECG (diagram shown): Shows the classic ST-segment elevation pattern:
  • P-Q-R-S-T complex labelled
  • The ST segment is elevated above the baseline (J-point elevation)
  • Labelled annotations show ST-ELEVATION, BASELINE, and ST-SEGMENT dimensions
  • This is the hallmark of STEMI (ST-Elevation Myocardial Infarction)
Biochemical Markers:
MarkerValueNormal
Troponin-I0.213 ng/ml<0.04 ng/ml (elevated 5x)
Total CK (Creatine Kinase)453 U/l<300 U/l (elevated)
Coronary Angiogram: 90% blockade in the Left Anterior Descending (LAD) artery
Diagnosis: Acute STEMI (LAD territory)
Classic presentation: risk factors (HTN + DM) + typical chest pain + ST elevation + markedly elevated Troponin-I (0.213 vs. normal <0.04) + elevated CK + 90% LAD blockade on angiogram = STEMI. LAD occlusion causes anterior wall MI.

SECTION 8: CYTOLOGY - CERVICAL CARCINOMA (Pages 21-22)

CASE 20 (Page 21 + 22) - Cervical Carcinoma

Page 21 (cytology images without text - belong to Case 20): Three cytological images shown:
  • Top image: Shows a cluster of cells that are squamous in appearance (polygonal cells with small nuclei and dense cytoplasm, some keratinized/orangeophilic) - this represents squamous epithelial cells from a cervical smear, showing marked variation in cell size and irregular nuclei
  • Bottom left: Dense cluster of small, dark (hyperchromatic), uniform cells in sheets - likely represents a poorly differentiated carcinoma cluster (high N:C ratio, irregular nuclei)
  • Bottom right: Cells with columnar/spindle morphology with elongated nuclei arranged in a palisade pattern - representing another morphological variant
Page 22:
Patient: 56-year-old female, low socioeconomic status. Postcoital bleeding for 2 months (the classic presenting complaint of cervical cancer).
Per-speculum Examination: Polypoid friable ulcerated mass in cervix that bleeds on touch (contact bleeding - hallmark of cervical carcinoma)
PAP Smear (left image): Shows:
  • Large malignant squamous cells with hyperchromatic (dark), irregular nuclei
  • Bizarre cell shapes including a tadpole/fiber cell (elongated keratinized cell)
  • High nuclear-to-cytoplasm ratio
  • Nuclear membrane irregularity
  • Background inflammation and necrotic debris (tumour diathesis)
  • These features = HSIL (High-Grade Squamous Intraepithelial Lesion) / Squamous Cell Carcinoma on Pap smear
Histopathology (right image): Shows:
  • Keratin pearl (epithelial pearl) - a concentric whorl of keratinized cells in the centre
  • Surrounding invasive nests of malignant squamous cells
  • Stromal desmoplastic reaction (fibrous stroma)
  • Mitotic figures visible
  • This is the hallmark of Well-differentiated Squamous Cell Carcinoma (SCC)
Diagnosis: Invasive Squamous Cell Carcinoma of the Cervix
Post-coital bleeding + friable cervical mass + PAP smear showing malignant squamous cells + histopathology with keratin pearls = Cervical SCC. This is the most common gynaecological cancer in developing countries, strongly associated with HPV infection (types 16 and 18).
