Let’s Talk Cervical Cancer

Cervical cancer develops in the cervix (the opening between the womb and va**na) and is one of the most preventable cancers yet many people don’t realise how important early screening is.

Almost all cervical cancers are caused by high risk HPV

In the early stages, there are often NO symptoms

That’s why regular cervical screening is essential for anyone aged 25–64 with a cervix

Common symptoms to watch for:

Unusual va**nal bleeding (after s*x, between periods or after menopause)

Unusual discharge

Pain during s*x or pelvic pain

If you notice any of these, contact your doctor,don’t wait. Early detection saves lives.

Prevention

Go for screening

Get the HPV vaccine if eligible

Avoid smoking

Practise safer s*x

Cervical cancer can often be prevented or treated early but only if we take action. Share this message to help raise awareness.

🔹 1. Viral Conjunctivitis

Cause: Viruses (commonly adenovirus)
Onset: Sudden, often after a cold or sore throat
Discharge: Watery or thin mucus
Symptoms:

Redness (especially on the inner side of eyelids)

Watery eyes

Burning or gritty sensation

Often starts in one eye → spreads to the other

Associated with preauricular lymph node swelling (small tender node near the ear)

Contagious: ✅ Highly contagious
Treatment: Supportive — artificial tears, cold compress, hygiene. (No antibiotics needed)

🔹 2. Bacterial Conjunctivitis

Cause: Bacteria (Staphylococcus, Streptococcus, Haemophilus, etc.)
Onset: Rapid
Discharge: Thick yellow or green pus, causing eyelids to stick together (especially in the morning)
Symptoms:

Red eyes

Swollen eyelids

Crusting and sticky lashes

Usually starts in one eye but may spread to the other

Contagious: ✅ Contagious
Treatment: Topical antibiotic drops or ointment (e.g., Tobramycin, Chloramphenicol)

🔹 3. Allergic Conjunctivitis

Cause: Allergy (pollen, dust, animal dander, etc.)
Onset: Seasonal or after allergen exposure
Discharge: Watery or stringy mucus
Symptoms:

Severe itching (main symptom)

Redness and swelling (especially of eyelids)

Both eyes affected simultaneously

May occur with sneezing or nasal allergy

Contagious: ❌ Not contagious
Treatment: Antihistamine or mast cell stabilizer eye drops (e.g., Olopatadine), cold compress, avoid allergens

🧠 Quick Summary Table

Feature Viral Bacterial Allergic

Discharge Watery Thick, purulent Watery/stringy
Itching Mild None Severe
Laterality One → both One → both Both
Contagious Yes Yes No
Treatment Supportive Antibiotic drops Antihistamine drops

Bell's palsy is a sudden weakness or paralysis on one side of the face caused by swelling or compression of the facial nerve. Symptoms include facial drooping, a sagging mouth or eyelid, drooling, and difficulty closing the eye on the affected side. While the exact cause is often unknown, it is linked to viral infections, and recovery typically begins within a few weeks, though full recovery may take months.

🔹 How to Interpret Corneal Topography
1. Look at the Color Scale (Curvature Map)
Warm colors (red/orange): Steeper areas of the cornea.
Cool colors (blue/green): Flatter areas of the cornea.
👉 A normal cornea shows a smooth, symmetric “bow-tie” pattern (with-the-rule astigmatism).
2. Check the Axial Map (Most Commonly Used)
Symmetric bow-tie = normal astigmatism.
Irregular/asymmetric bow-tie = irregular astigmatism, suspect keratoconus or ectasia.
Central steepening = keratoconus.
Peripheral steepening = pellucid marginal degeneration.
3. Evaluate Keratometry Values (K1 & K2)
Normal cornea: 40–48 D.
K > 47 D: Suggestive of keratoconus/ectasia.
High difference (>3 D) between K1 & K2: Significant astigmatism.
4. Look at the Elevation Map
Shows cornea compared to a “best fit sphere.”
Red/orange elevation areas: High risk of ectasia.
Useful for keratoconus screening.
5. Check Pachymetry Map (Thickness)
Central cornea normally ~540 µm.
Thin cornea (

🧬✂️ CRISPR Just Cut HIV Out of Human Immune Cells — And It’s Not Coming Back

In a groundbreaking achievement, scientists have used CRISPR/Cas9 to completely delete HIV-1 DNA from human T-cells — not just suppress it.

The result?
✅ Virus removed from the immune system’s core cells
✅ Edited cells resisted reinfection in lab tests
✅ A potential path to a permanent cure

This could be the game-changer the world has been waiting for — tackling HIV at its genetic roots and removing it from the body once and for all.
