This document discusses pulmonary embolism (PE), including its incidence, sources, clinical presentation, investigations, and treatment. Some key points:
- PE is a common postoperative complication and causes 2-3% of hospital mortalities. Sources include deep vein thrombosis (DVT), infective endocarditis, and fat or amniotic fluid embolism.
- Clinical presentation depends on embolism size - small emboli may be asymptomatic, medium emboli can cause infarction or chest pain/dyspnea, and massive PE severe chest pain and shock.
- Investigations include blood tests, CT, lung scan, and pulmonary angiography. Treatment involves anticoagulation for DVT prophyl

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

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

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 Reports of Gastric Ultrasound
2. These items will be discussed:
• 1- Incidence
• 2- Sources of emboli
• 3- Clinical presentation
• 4- Investigations
• 5- Treatment
3. 1- Incidence
• Statistics about the incidence of pulmonary in
Egypt is Widely variable and unreliable but
DVT & PE are common post operative
complications
• 2-3 % of all hospital mortalities are due to PE
4. 2- Sources of emboli
• DVT (most common)
• Infective endocarditis and thrombi of the Rt
side of the heart
• Fat embolism ( Bone fracture)
• Amniotic Fluid Embolism
• Air Embolism
6. 3- Clinical Picture:
• According to the size of Embolism
1- Small sized emboli
(impacted in peripheral arterioles)
2- Medium sized emboli
(impacted in branches of pulmonary a.)
3- Large sized emboli
(in main Pulmonary a. or one of its branches)
7. 1- Small sized emboli
• Usually asymptomatic but cough, dyspnea or
chest discomfort may occur.
• Recurrent small emboli with obliteration of
more than 65% of pulmonary vascular bed
leads to thromboembolic pulmonary
hypertension that leads RV++ & RHF
( subacute corpulmonale)
8. 2- Medium sized emboli
• Leads to pulmonary infarction
• CO
- cough - Haemoptysis
- Pleuritic chest pain - Dyspnea
- Fever
• OE
- Pleural rub
- Crepitations over the involved area (may be)
19. 5- Treatment
• Prophylaxis & TTT of DVT is very important in
prevention of PE:
• Prophylaxis:
1- Early mobilization after surgeries
2- Exercises of the leg in bed
3- Elastic stocks
4- Adequate hydration postoperative
5- Anticoagulant in high risk patients
( low dose heparin 5000 IU S.C 2 hrs before operation &
every 12 hrs post. Till the pt. is ambulant.
OR LMWH at the night of the operation & 12 hrs post.)
20.
21. • 2- Oral anticoagulant (Warfarin)
- Heparin is discontinuated after 3 days
of overlap TTT.
- needs follow up by INR (PT)
- Given for 3-6 months & if liable for
rethrombosis warfarin is given for life
22. TTT of massive PE
• Resuscitation:
1- Oxygen therapy
2- Analgesics >>> Pethidine
3- Dobutamine may improve RV function
4- CPR if arrest
23. • Thrombolytic therapy:
- Cardiac catheter is inserted into the pulmonary
artery & 600000 units of Streptokinase are injected
followed by 100000 unitshr for 72 hrs.
• Catheter Suction Embolectomy:
Via the IJV or CFV by local anaesthesia & under image.
• Urgent open pulmonary embolectomy:
24. TTT of mild to moderate PE
• Anticoagulant therapy:
as DVT
• For recurrent small emboli that cause
