This document discusses the management of anterior uveitis. It begins by defining anterior uveitis and its subtypes. It then outlines the investigations performed which include hematological, radiological, skin and biopsy tests. Treatment involves non-specific local and systemic therapies like cycloplegic drugs, corticosteroids, NSAIDs and immunosuppressants. Specific treatment targets the underlying cause if identified. Complications are managed separately. Hypopyon, a sign of severe inflammation, is also explained.

The skin is not only the largest organ of the body, but it also forms a living biological barrier with several functions.
Pyodermas are any pyogenic skin disease (has pus). Skin infections can be caused by bacteria (often Staphylococcal or Streptococcal) either invading normal skin, or affecting a compromised skin barrier
Some bacterial skin infections resolve without serious morbidity. However, skin infections can be severe and result in sepsis or death, particularly in vulnerable patient groups.

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. • Inflammation of the uveal tissue from iris upto
pars plicata of the ciliary body.
• Subdivided into :
– Iritis – iris
– Iridocyclitis – iris + pars plicata equally
– Anterior cyclitis – pars plicata
3. Investigations
• Thorough ocular examination.
1) Haematological investigations
• TLC and DLC to have a general information about
inflammatory response of body.
• ESR to ascertain existence of any chronic inflammatory
condition in the body.
• Blood sugar levels to rule out diabetes mellitus.
• Blood uric acid in patients suspected of having gout.
• Serological tests for syphilis, toxoplasmosis and
histoplasmosis.
• Tests for antinuclear antibodies, Rh factor, LE cells, C-
reactive proteins antistreptolysin-0, ACE (for
sarcoidosis).
4. • 2) Urine examination for WBCs, pus cells, RBCs and
culture to rule out urinary tract infections.
• 3) Stool examination for cyst and ova to rule out
parasitic infestations.
• 4) Radiological investigations include:
• X-rays of chest, paranasal sinuses, sacroiliac joints
and lumbar spine.
• CT scan high resolution. CT scan of thorax should
be considered for suspected sarcoidosis cases.
• MRI scan of head for suspected sarcoidosis,
demyelination and lymphomas.
• 5) Skin tests. These include tuberculin test, Kveim’s
test for sarcoidosis, toxoplasmin test, lepromin test
and pathergy test for Behcet’s disease.
5. • 6. Biopsy/intraocular fluid samples for
examination
– Aqueous samples for PCR
– Vitreous biopsy for culture and PCR
– Lungs and lymph node biopsy for sarcoidosis
6. Treatment
• I) Non specific treatment
(A) Local therapy
1) Cycloplegic drugs – very effective during acute phase
– Commonly used : 1% atropine sulfate eye ointment or
drops instilled 2-3 times a day
– Atropine allergy - 2% homatropine or 1% cyclopentolate
eyedrops may be instilled 3-4 times a day
– For more powerful cycloplegic effect : a subconjunctival
injection of 0.25 ml in mydricain (a mixture of atropine,
adrenaline and procaine)
– should be continued for at least 2–3 weeks after the eye
becomes quiet, otherwise relapse may occur.
7. • Mode of action :
– (i) gives comfort and rest to the eye by relieving
spasm of iris sphincter and ciliary muscle
–(ii) prevents the formation of synechiae and
may break the already formed synechiae
–(iii) reduces exudation by decreasing
hyperaemia and vascular permeability
–(iv) increases the blood supply to anterior uvea
by relieving pressure on the anterior ciliary
arteries.
8. 2) Corticosteroids
• Commonly used preparations contain - dexamethasone,
betamethasone, hydrocortisone or prednisolone
• Route of administration :
– (i) eye drops 4–6 times a day
– (ii) eye ointment at bed time
– (iii) Anterior sub-Tenon injection is given in severe cases
• Mode of action :
– They reduce inflammation by their anti-inflammatory effect
– Anti-allergic - used in allergic type of uveitis
– Antifibrotic activity - they reduce fibrosis and thus prevent
disorganisation and destruction of the tissues.
9. (B) Systemic therapy
1) Corticosteroids
– a definite role in nongranulomatous iridocyclitis, where
inflammation, most of the times, is due to antigen-antibody
reaction.
– anti-inflammatory and antifibrotic effects
– indicated in intractable anterior uveitis resistant to topical
therapy
• Dosage : Treatment is started with high doses of
prednisolone (60–100 mg) or equivalent quantities of
other steroids (dexamethasone or betamethasone).
– Daily therapy regime is preferred for marked inflammatory
activity for at least 2 weeks.
– In the absence of acute disease, alternate day therapy
regime should be chosen.
– Dose of steroids is decreased by a week’s interval and
tapered completely in about 6–8 weeks in both the regimes
10. 2) NSAIDs
• Can be used where steroids are
contraindicated.
• In uveitis associated with rheumatoid disease
- Phenylbutazone and oxyphenbutazone
• Ankylosing spondylitis - Naproxen
11. 3) Immunosuppressive drugs
• Should be used only in desperate and extremely
serious cases of uveitis, in which vigorous use of
steroids have failed to resolve the inflammation
and there is an imminent danger of blindness.
• Indications : Severe cases of Behcet’s syndrome,
sympathetic ophthalmia, pars planitis and VKH
syndrome.
• Eg : cyclophosphamide, chlorambucil and
methotrexate
12. Azithromycin or tetracycline or
erythromycin
• To treat chlamydial infection in patients and
their sexual partners with Reiter’s syndrome
having urethritis and iritis.
13. (C) Physical measures
• 1. Hot fomentation. It is very soothing,
diminishes pain and increases circulation, and
thus reduces the venous stasis. As a result, more
antibodies are brought and toxins are drained.
Hot fomentation can be done by dry heat or wet
heat.
• 2. Dark goggles. These give a feeling of comfort,
especially when used in sunlight, by reducing
photophobia, lacrimation and blepharospasm
14. II) Specific treatment of the cause
• Nonspecific treatment is very effective and usually
controls the uveal inflammation, in most of the cases,
but it does not cure the disease, resulting in relapses
• All possible efforts should be made to find out and
treat the underlying cause
• Eg : a full course of antitubercular drugs for underlying
Koch’s disease, adequate treatment for syphilis,
toxoplasmosis
• When no cause is ascertained, a full course of broad
spectrum antibiotics may be helpful by eradicating
some masked focus of infection in patients with
nongranulomatous uveitis.
15. III) Treatment of complications
• 1. Inflammatory glaucoma
– Drugs to lower intraocular pressure such as 0.5%
timolol maleate eyedrops twice a day and tablet
acetazolamide (250 mg thrice a day)
– Pilocarpine and latanoprost eye drops are
contraindicated in inflammatory glaucoma
• 2. Post inflammatory glaucoma
– Treated by laser iridotomy
– Surgical iridectomy may be done when laser is not
available
16. • 3. Complicated cataract requires lens
extraction. Presence of fresh KPs is considered
a contraindication for intraocular surgery
• 4.Retinal detachment of exudative type
usually settles itself if uveitis is treated
aggressively. A tractional detachment requires
vitrectomy and management of complicated
retinal detachment, with poor visual
prognosis.
• 5. Phthisis bulbi especially when painful,
requires removal by enucleation operation
17. Hypopyon :A hypopyon consists of polymorphonuclear
leucocytes which accumulate in the lower angle of the
anterior chamber and eventually become enmeshed in
a network of fibrin
19. Mechanism of development
• Diffusion of bacterial toxins results in iritis
• When iritis is severe, massive outpouring of
leucocytes from the vessels occurs – the cells
gravitate to the bottom of the anterior
chamber
• Pseudohypopyon – due to collection of tumor
cells
20. • The development of a hypopyon depends on two
factors: (i) the virulence of the infecting organism
and (ii) resistance of the tissues.
• Hypopyon ulcers are much more common in old,
debilitated or alcoholic subjects.
• Hypopyon is usually sterile – the leucocytosis is
due to toxins and not due to actual invasion by
bacteria
• Descemet’s membrane is impermeable to
bacteria and leucocytes – this accounts for the
ease and rapidity with which it is often absorbed
21. Grading
• H0 – Absent
• + - less than 2mm
• ++ - less than 5mm (filling up to half of
anterior chamber
• +++ - 5mm or more (filling more than half of
anterior chamber)
22. Management
• It may develop in an hour or two,rapidy
disappear and readily reappear
• It is usually unnecessary to remove the pus; if
ulcerative process is controlled, it will be
absorbed
• In some cases of recalcitrant fungal ulcers, an
anterior chamber tap to test the hypopyon for
fungal invasion , followed by an anterior chamber
wash with antifungals may be required
23. • Hypopyon can cause secondary glaucoma –
treated with 0.5% timolol maleate, bid eye
drops and oral acetazolamide
• If source of infection is dacryocystitis –
dacryocystectomy
