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
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

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!
New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

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

2. CASE REPORT
A 26-year-old female was referred for extraction of
her upper left third molar due to irreversible pulpitis.
The patient had no medical concerns contraindicating
the extraction. One cartridge of 1.8 ml 2% lidocaine
with 1:80000 adrenaline was administered with 27-
gaug short needle on non-aspirating syringe. The
tooth was luxated with elevator, and removed with
forceps. Shortly after extraction the patient reported
double vision. Ocular examination revealed normal
pupils, no evidence of ptosis or conjunctivitis. Ocular
movements in all direction were normal except that
the left eye can not abduct past the midline.
4. DIPLOPIA
Diplopia occurs in two forms:
1. Monocular Diplopia: patient experiences
double vision in only one eye.
2. Binocular Diplopia: It occurs only when both
eyes are working together
5. DIPLOPIA
Diplopia can be:
1. Horizontal; images beside each other
2. Vertical; images above each other
3. Oblique; images separated horizontally and
vertically
6. DIPLOPIA
Since much of the vision is binocular, it is
clear that a very high order of coordination of
movements of the two eyes is necessary if
visual images are to fall at all times on
corresponding points in the two retinas and
diplopia is to be avoided.

12. OCULAR COMPLICATIONS OF LOCAL
ANAESTHESIA
Diplopia (double vision)
Amaurosis (Blindness)
Palpebral ptosis (dropping of eyelid)
Mydriasis (dilation of pupil)
Miosis (constriction of pupil)
Horner-like syndrome (ptosis, miosis, enophthalmos and
vascular dilatation of the conjunctiva)
13. OCULAR COMPLICATIONS OF LOCAL
ANAESTHESIA
For the past 45 years, ocular complications
after middle or posterior alveolar nerve block
were reported twice more frequent than
inferior alveolar nerve block. A literature
review by the author of the present paper
reveals more than 20 cases of ocular
complications after IANB. About two thirds of
cases had ocular complications of diplopia.
Chun-kei Lee 2006
Dental Bulletin
14. OCULAR COMPLICATIONS OF LOCAL
ANAESTHESIA
In the literature, only very few cases of ocular
complications were reported in children. This may be
due to the temporary effect of the complication and
its rapid recovery without sequelae but it has been
queried that these complications are under-reported.
Moreover, it has been suggested that sudden
monocular amaurosis may pass unnoticed by the
patient and cases of visual disturbance following local
anesthesia in dentistry occur more often than are
recognised.
Chun-kei Lee 2006
Dental Bulletin
15. OCULAR COMPLICATIONS OF LOCAL
ANAESTHESIA
ophthalmologic complications after dental
anesthesia might be more common than
reported to date. The benign and transient
nature of these conditions and their resolution
without sequelae may be the reason for this
scant representation in the literature.
Peñarrocha-Diago & Sanchis-Bielsa 2000
Oral Surg Oral Med Oral Pathol
16. OCULAR COMPLICATIONS OF LOCAL
ANAESTHESIA
The symptoms develop immediately after the
injection of the anesthetic solution and can
persist for between 1 minute and several
hours, though they only very rarely exceed
the duration of the anesthetic effect.
Average duration for diplopia was 50 minutes
Peñarrocha-Diago &Sanchis-Bielsa 2000
J. Oral Surg Oral Med Oral Pathol
17. DIPLOPIA
In case of paralysis of the extrinsic musculature of
the eye (especially the external rectus muscle),
synchronic movement of the eyes becomes
impossible, and diplopia appears.
Peñarrocha-Diago 2000
J. Oral Surg Oral Med Oral Pathol
18. DIPLOPIA
External rectus muscle palsy, with ocular
abduction difficulties, is the most frequent
finding

19. Symptoms and signs of lateral rectus paralysis
Symptom:
Diplopia
Signs:
1- Esotropia
2- Inability to abduct the affected eye
Kelly R. Magliocca et al 2006
J. Oral Surg Oral Med Oral Pathol
20. DIPLOPIA
Most of the cases reported in the literature
were produced by both lidocaine and
mepivacaine. These complications could also
be caused by articaine, in our opinion,
because of its improved bone diffusion.
Peñarrocha-Diago 2000

21. Hypothesis of ocular complications
Bony pathways
Direct flow of local anaesthetic
solution through the inferior
orbital fissure from:
1. pterygopalatine fossa
2. infratemporal fossa
22. Hypothesis of ocular complications
Vascular pathways
Intra-arterial injection of local
anaesthetic in patients with
uncommon vascular pattern
1. Solution is deposited within the
posterior superior alveolar
artery and forced back into the
maxillary artery and
subsequently into the middle
meningeal artery and then into
the ophthalmic artery
23. Hypothesis of ocular complications
Vascular pathways
Intra-arterial injection
2. Solution is deposited within the
inferior alveolar artery and
forced back into the maxillary
artery and subsequently into
the middle meningeal artery
and then into the ophthalmic
artery
24. Hypothesis of ocular complications
Vascular pathways
Intra-venous injection
of anaesthetic solution:
1. Solution reaches the
abducent nerve within
the cavernous sinus,
arriving via the
pterygoid plexus
25. Hypothesis of ocular complications
Vascular pathways
Intra-venous injection
2. Solution reaches the
inferior ophthalmic vein
via the pterygoid plexus
or its communicating
branches
26. MANAGEMENT OF DIPLOPIA
1. Reassure patients as to the usually transient
nature of these complications
2. Cover the affected eye with a gauze dressing
to protect the cornea and restore normal
monocular vision for the duration of
anaesthesia
Chun-kei Lee 2006
Dental Bulletin
27. MANAGEMENT OF DIPLOPIA
3. The patient should be escorted home by a
responsible adult, since monocular vision is
devoid of distance-judging capability
4. Should the complication last longer than 6
hours, refer the patient to an
ophthalmologist for evaluation
Chun-kei Lee 2006
Dental Bulletin
28. COCLUSION
The physical signs of an inadvertent paresis
of the abducent nerve will no doubt alarm the
unprepared clinician. For the patient’s benefit,
a calm demeanor is imperative. The patient
can be assured of a good prognosis since
cessation of symptoms generally occurs
within a few hours.
