This document summarizes the best medical treatment of venous insufficiency in 2013. It discusses the epidemiology, etiology, socioeconomic aspects, and management of chronic venous disorders. It provides details on medical therapeutic methods, including venoactive drugs, compression therapy, and lifestyle adaptations. It evaluates the efficacy of various venoactive drugs like calcium dobesilate, MPFF, and hydroxyethyl rutosides in treating symptoms and venous leg ulcers based on clinical trials and meta-analyses. It also explains the effects of drugs on the macrocirculation, microcirculation, and leukocyte-endothelium interaction in attenuating venous inflammation.
Venous thrombectomy can help treat acute iliofemoral deep vein thrombosis (DVT) and reduce long-term complications. The procedure removes the thrombus to eliminate obstruction and preserve valve function. Randomized trials found that venous thrombectomy plus anticoagulation led to better long-term outcomes than anticoagulation alone, including lower venous pressures, less venous reflux, fewer symptoms of post-thrombotic syndrome, and better patency rates. Contemporary venous thrombectomy techniques use dual catheter techniques and angiovenous fistulas to effectively clear thrombus and reduce venous hypertension in order to decrease long-term morbidity from extensive DVT.

Recent management of primary varicose veinsMohamed Kabis
This document discusses the classification and management of primary varicose veins. It describes the CEAP classification system used to classify venous disease based on clinical, etiological, anatomical and pathophysiological factors. For primary varicose veins, the recommended treatments include venoactive drugs, compression stockings, saphenous vein ablation or stripping, sclerotherapy, and phlebectomy. Recurrence after surgery is common due to neovascularization, and endovenous ablation has become the preferred treatment for recurrent varicose veins.
Actinic keratoses: Erythematous scaly lesions on sun-damaged skin & considered “precancerous” lesions that have the potential to progress into invasive SCC.
Bowen’s disease: SCC in situ It has the potential to progress to invasive SCC.
Leukoplakia: Leukoplakia refers to a white patch or plaque on the oral mucosa that cannot be wiped off and cannot be characterized clinically or pathologically as any other disease.
This document discusses various treatment options for varicose veins, including conservative management using compression bandages and stockings, medications to improve lymph flow and protect veins, sclerotherapy to harden problematic veins, and surgical procedures such as vein ligation and stripping. More minimally invasive options like endovenous laser ablation and radiofrequency ablation are also covered, which involve inserting a laser or radiofrequency catheter into the vein to cause thermal damage and occlusion. All treatments have potential complications like pain, bruising, bleeding, or deep vein thrombosis.
Neuropathy, deformities, limited joint mobility, and gait abnormalities in diabetics alter biomechanics and increase plantar pressures. Neuropathy is a primary factor, reducing sensation and muscle function. Deformities like claw toes and equinus contractures further increase pressures. Limited joint mobility from collagen crosslinking reduces shock absorption. Together, these changes cause abnormal gait and high pressures, risk factors for foot ulceration in over 63% of cases. Early intervention to prevent deformities and reduce pressures can help avoid ulcers.

The document discusses endovenous radiofrequency ablation (RFA) for treating varicose veins caused by venous reflux disease. It notes that over 25 million Americans suffer from venous reflux disease, which often leads to varicose veins. RFA uses a catheter-based approach to deliver radiofrequency energy to heat and collapse the vein, providing an alternative treatment to surgery. Studies show RFA results in high occlusion rates with less pain and bruising than laser ablation treatment.
Varicose Veins were first documented by Sushrutha in India as "Siragranthi". The first surgery for varicose veins was described by Galen in 2nd century AD. Varicose veins are dilated, elongated and tortuous superficial veins caused by venous hypertension due to valvular incompetence or obstruction. Investigations like Doppler ultrasound and air plethysmography help in diagnosis. Management includes conservative measures, sclerotherapy, surgery like vein stripping or ligation of saphenofemoral junction, and newer minimally invasive procedures like radiofrequency ablation and endovenous laser ablation.
This document summarizes systemic therapy options for malignant melanoma, including cytotoxics, immunotherapy, targeted therapies, and their outcomes. Key points discussed are: (1) Immunotherapy with checkpoint inhibitors like ipilimumab and pembrolizumab have significantly improved response rates and survival compared to traditional chemotherapies; (2) Combining BRAF and MEK inhibitors has become an important targeted therapy approach as it improves outcomes over BRAF inhibitors alone by delaying resistance; (3) Emerging evidence suggests combining immunotherapy and targeted therapies may provide further benefit.

Chordoma is a rare, slow-growing bone cancer that arises from notochord remnants in the axial skeleton. It has a predilection for the skull base, sacrum, and spine. Management involves maximal safe resection followed by radiation therapy, as chordomas are locally aggressive and have a poor long-term prognosis.
This document provides guidelines for foam sclerotherapy treatment of varicose veins and superficial venous insufficiency. It discusses indications for treatment, sclerosing agents such as polidocanol and sodium tetradecyl sulfate, how to make and administer foam, and results from studies on occlusion rates. Foam sclerotherapy is recommended for treating saphenous veins and tributaries as it displaces blood better than liquid sclerosants, allowing for more effective endothelial contact and occlusion rates of 70-90% in studies with follow-ups of 6-46 months and a single treatment session in most cases. Compression is also important after the procedure.
Varicose veins are dilated, elongated superficial veins caused by venous hypertension. They commonly affect the lower limbs and long saphenous system. Risk factors include prolonged standing, family history, pregnancy, aging, deep vein thrombosis, oral contraceptives and obesity. Left untreated, varicose veins can develop into varicose ulcers, which are chronic non-healing wounds above the ankle caused by damaged skin from high blood pressure in the leg veins. Conservative treatments include compression bandages, leg elevation and addressing underlying risk factors. Sclerotherapy involves injecting chemicals to obliterate veins, while surgical options are high ligation and stripping of veins. Post-procedure care involves rest, compression stockings, elevation and
Peripheral Arterial Occlusive Disease (PAOD) is atherosclerosis of the arteries in the extremities, causing reduced blood flow and ischemia. It affects up to 10% of people over 65 in Western countries. Left untreated, mortality rates increase to 30% at 5 years, 50% at 10 years, and 70% at 15 years. Risk factors include diabetes, hypertension, smoking, and family history. Smoking is the greatest risk factor and cessation is paramount for treatment.

Low dose dopamine increases GFR and RBF. The DAD-HF trial investigated 60 patients randomized to low dose furosemide (continuous infusion 0.5 mg/kg/day) with or without low dose dopamine (2 μg/kg/min). Dopamine preserved renal function compared to furosemide alone in patients with acute decompensated heart failure. There were no significant differences found in a trial comparing high vs low dose furosemide or bolus vs continuous infusion on renal function or symptoms. Novel agents targeting fluid overload, renal function, contractility, and vasomotion may provide new therapeutic options for acute heart failure.
Prof. U. C. SAMAL provides an overview of acute decompensated heart failure and what is new in the field. He discusses similarities and differences between acute myocardial infarction and acute heart failure syndromes. Mortality rates are high for both conditions, though clinical benefits of interventions are greater for acute MI based on published clinical trials. The document then discusses definitions and classifications of acute heart failure syndromes, as well as guidelines for diagnosis and treatment from ESC and ACC/AHA. Biomarkers that can help with diagnosis, prognosis, and guiding therapy are also summarized.

1. Pazopanib is a tyrosine kinase inhibitor that has shown activity against soft tissue sarcomas in phase II trials.
2. A phase III randomized controlled trial of pazopanib versus placebo in patients with advanced soft tissue sarcomas found that pazopanib significantly prolonged progression-free survival compared to placebo.
3. The most common adverse events with pazopanib were fatigue, diarrhea, nausea, decreased appetite, hypertension, and hair color changes, though most were grade 1 or 2.
This document summarizes a randomized controlled trial that investigated whether stable patients with infective endocarditis on the left side of the heart could be safely treated with oral antibiotics instead of continued intravenous antibiotics. The trial involved 400 patients randomized to either continued intravenous or oral antibiotic treatment according to predefined regimens. The primary outcome was a composite of death, embolic events, or recurrence of infection. The results showed that oral antibiotic treatment was noninferior to continued intravenous treatment.
This document summarizes a presentation given by Prof Kyaw Soe Win on arterial health in hypertension. The presentation covered:
- Cardiovascular diseases are now major causes of mortality, with hypertension as a common risk factor.
- Lifestyle changes like urbanization have led to increased stress and sedentary lifestyles, contributing to rising hypertension rates globally.
- Treating hypertension can significantly reduce cardiovascular outcomes. More intensive control of blood pressure through 24-hour coverage can further reduce risks.
- Choosing antihypertensive drugs that improve arterial health in addition to blood pressure control may maximize cardiovascular protection. Perindopril was highlighted as having properties that protect the endothelium.
Venous Thromboembolism (VTE): Recent Advances in Reducing the Disease BurdenNBCA
- Venous thromboembolism (VTE), which includes deep vein thrombosis (DVT) and pulmonary embolism (PE), is a major cause of morbidity and mortality worldwide. It is estimated that there are 900,000 cases of VTE per year in the US.
- Recent clinical trials have found that the direct oral anticoagulants rivaroxaban, apixaban, edoxaban and dabigatran are non-inferior to standard therapy for treating VTE and reduce the risk of recurrence, while having a similar or lower risk of bleeding.
- The EINSTEIN DVT and EINSTEIN PE trials found that rivaroxaban was non-infer
1) Chronic Venous Insufficiency (CVI) results from venous reflux or obstruction leading to venous hypertension.
2) Risk factors for CVI include older age, female sex, family history, obesity, and prolonged standing.
3) Treatment options for CVI range from conservative measures like compression stockings to interventional procedures like phlebectomy (surgical removal of varicose veins) and radiofrequency or laser ablation.

Why Psychological Safety Matters for Software Teams - ACE 2024 - Ben Linders.pdfBen Linders
Psychological safety in teams is important; team members must feel safe and able to communicate and collaborate effectively to deliver value. It’s also necessary to build long-lasting teams since things will happen and relationships will be strained.
But, how safe is a team? How can we determine if there are any factors that make the team unsafe or have an impact on the team’s culture?
In this mini-workshop, we’ll play games for psychological safety and team culture utilizing a deck of coaching cards, The Psychological Safety Cards. We will learn how to use gamification to gain a better understanding of what’s going on in teams. Individuals share what they have learned from working in teams, what has impacted the team’s safety and culture, and what has led to positive change.
Different game formats will be played in groups in parallel. Examples are an ice-breaker to get people talking about psychological safety, a constellation where people take positions about aspects of psychological safety in their team or organization, and collaborative card games where people work together to create an environment that fosters psychological safety.

Carrer goals.pptx and their importance in real lifeartemacademy2
Career goals serve as a roadmap for individuals, guiding them toward achieving long-term professional aspirations and personal fulfillment. Establishing clear career goals enables professionals to focus their efforts on developing specific skills, gaining relevant experience, and making strategic decisions that align with their desired career trajectory. By setting both short-term and long-term objectives, individuals can systematically track their progress, make necessary adjustments, and stay motivated. Short-term goals often include acquiring new qualifications, mastering particular competencies, or securing a specific role, while long-term goals might encompass reaching executive positions, becoming industry experts, or launching entrepreneurial ventures.
Moreover, having well-defined career goals fosters a sense of purpose and direction, enhancing job satisfaction and overall productivity. It encourages continuous learning and adaptation, as professionals remain attuned to industry trends and evolving job market demands. Career goals also facilitate better time management and resource allocation, as individuals prioritize tasks and opportunities that advance their professional growth. In addition, articulating career goals can aid in networking and mentorship, as it allows individuals to communicate their aspirations clearly to potential mentors, colleagues, and employers, thereby opening doors to valuable guidance and support. Ultimately, career goals are integral to personal and professional development, driving individuals toward sustained success and fulfillment in their chosen fields.

Suzanne Lagerweij - Influence Without Power - Why Empathy is Your Best Friend...Suzanne Lagerweij
This is a workshop about communication and collaboration. We will experience how we can analyze the reasons for resistance to change (exercise 1) and practice how to improve our conversation style and be more in control and effective in the way we communicate (exercise 2).
This session will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
Abstract:
Let’s talk about powerful conversations! We all know how to lead a constructive conversation, right? Then why is it so difficult to have those conversations with people at work, especially those in powerful positions that show resistance to change?
Learning to control and direct conversations takes understanding and practice.
We can combine our innate empathy with our analytical skills to gain a deeper understanding of complex situations at work. Join this session to learn how to prepare for difficult conversations and how to improve our agile conversations in order to be more influential without power. We will use Dave Gray’s Empathy Mapping, Argyris’ Ladder of Inference and The Four Rs from Agile Conversations (Squirrel and Fredrick).
In the session you will experience how preparing and reflecting on your conversation can help you be more influential at work. You will learn how to communicate more effectively with the people needed to achieve positive change. You will leave with a self-revised version of a difficult conversation and a practical model to use when you get back to work.
Come learn more on how to become a real influencer!

18. Mode of Action of Venoactive Drugs
1- Effects on Macrocirculation
Most VADs increase the venous tone by a
mechanism related to noradrenaline pathway.
Especially. MPFF and hydroxyethylruosides
have more affinity to venous wall.
Last studies show that CVD is closely related to
primary insufficiency of venous valves origined
from inflammation.
MPFF: Potential anti-inflammatory effect on an
animal model of acute venous HT. The
protective effect on venous valves in CVD..
19. 2-Effects on Microcirculation
Capillary resistance:: To increase capillary resistance
and to decrease capillary filtration.
Especially MPFF enhanced inhibition of
adhesion of leukocytes on capillariees by
micronisation..
Lymphatic drainage
Coumarin and rutin edema lysis effect by proteolysis.
MPFF: increase both lymphatic flow and lymphatic
channels
Ca dobesilate: increases lymphatic drainage.
20. Protection against inflammation: The attenuation of
inflammatory response by free radical scavenging,
anti-elastase and anti-hyaluranidase properties of
VADs (rutosides, escin, ruscus extracts,
proanthocyanidines, Ca dobesilate, MPFF).
Hemorrheological disorders: Inflammation
increased fibrinogen, plasma volume contraction,
increased blood viscosity accumulation of
huge red cell aggregates around the venules,
reduced blood flow and poor O2 delivery
lipodermatosklerosis.
Decrease in viscosity: MPFF, Ca dobesilate,
Increase in red cell velocity: MPFF
21. Efficacy on edema of Venous Origin
The confirmed efficacy by meta analyses: MPFF, Ca
debosilate, rutosides, escin, proanthocyanidine and
coumarin rutin..
Pharmacological Treatment of Leg Ulcers
Only MPFF: This efficacy was confirmed in 2005 by a
meta-analysis of 5 trials using MPFF as an adjunct
to standard treatment in 723 patients of stage 6 of
the CEAP classification.
23. At the level of microcirculation: Hyperpressure at the capillary level induces capillary leakage
allowing the accumulation of fluids, protein, and red blood cells in the interstitial space, forming
edema. Red blood cell degradation products and protein extravasations are the initial inflammatory
signals that result in leukocyte migration into the interstitial space..

1-“Early treatment aimed at
preventing venous hypertension,
reflux, and inflammation could
alleviate symptoms of chronic
venous disease and reduce the risk
of ulcers.”
2-“Treatment to inhibit inflammation
may offer the greatest opportunity to
prevent disease–related
complications.”
27. • Among the medical therapy options, especially
MPFF has a confirmed protective effect on
mıcrocirculation against the ambulatory venous
hypertension.
• MPFF attenuates the leukocyte/endothelium
interaction by inhibiting and/or reducing the
release of endothelial intercellüler adhesion
molecule I, vasculary cell adhesion molecule
and some other leukocyte adhesion molecules.
28. • The healing effect of MPFF is most evident in
patients with leg ulcers.
• The patients who were treated with MPFF and
compression combination showed 32% better
healing rate than the patients who were treated
topical care and compression alone during 6-
month follow-up.
29. Other Drugs Having Effect on Venous System
• Pentoxifilline: Reduces leukocyte adhesion and erythrocyte
aggregation, and a mild fibrinolytic action. Although it is relatively
well tolerated, its value for treating leg ulcers remain debatable
until new data become available.
• Stanozolol: Stanozolol (stanazol), an anabolic steroid, stimulates
blood fibrinolysis and has been evaluated with several
randomized trials for the treatment of the more advanced skin
changes associated with lipodermatosclerosis. and it possibly
faster ulcer healing rates.
• Prostoglandins E: Augments blood flow in the capillaries,
increases fibrinolytic activity, reduces platelet and leukocyte
aggregation and adhesion to endothelium. A significant
improvement in the status of leg ulcers with intra-venous
systemic application. (No recommendation can be made)
• Topical prostacyclin-Iloprost: Local application to the ulcer edge
and surrounding skin. No clear benefit.
30. VAD Adverse Events
• Safety of VADs is in general good and well
tolerated,
• Hepatotoxicity: Coumarin and benzarone,
• Gastrointestinal and autonomic adverse
events, 5%,
• Usage in pregnancy: Some VADs have
been used without any problem during 2.
and 3. trimester of pregnancy, but there
are no long-term series documenting this.
• Caution is recommended during breast
feeding also.
31. INDICATIONS FOR VADs
• Symptomatic CVD: Heavy legs, pain, resless legs, night
cramps, itching, numbness. If there is no symptom
recurrence; max. 3-month usage. Combined usage of VADs
is not appropriate.
• Anti-edema effecti: A clear effect proved by double-blind
studies
• Lymphedema, MPFF, Coumarine and rutin, Ca dobesilate
• Venous ulcer treatment: MPFF,
• Additive effect in combination with sclerotherapy, surgery
and compression.
• Compression + VAD > compression,
• Compression necessary but contra-indicated (arterial
insufficiency, neuropathies),
• Topical treatment: VADs + heparinoids (anti-inflammatory
effect + analgesic effect by inactivating histamine and anti-
thrombotic effect),
• Prevention of venous hypertension and inflammation,
protection of venous valves; MPFF

• Only, the superiority of multi-layer (four layer) bandaging
was shown in treatment of active venous ulcers.
36. Intermittant pneumatic compression devices
• Shortens the healing time in treatment of active
venous ulcers. (recommendation and evidence

Caution in arterial insufficiency:
Can not be used if the patient
has ABI<0,4, or can be used
after revascularization
Should not be used in dermatitis
origined from synthetic
materials used for compression.
37. Adaptation of lifestyle
There is no evidence-based recommendation
about their efficacy.
• Walking exercises
• Avoiding from long-time stand up position
• Avoiding from obesity
• Leg elevation and bed rest
• Avoiding from heat, hot water
38. Ineffective adjuncts to ulcer care
• Hyperbaric oxygen —
• Electromagnetic therapy — .
• Therapeutic ultrasound —
• Medical management of lower extremity chronic venous disease
Literature review current through: Sep 2013.
39. Conclusion
• The combination of medical treatment with
compression provides considerably superior healing
results and better life quality than the compression
alone.
• Medical treatment has a considerable efficacy in
almost every stages of CVD by both alleviating the
symptoms and preventing the progression of
symptoms as well as complications.
Editor's Notes
Among the many proposed mechanisms linking venous hypertension to macroscopic and microcirculatory changes, “leukocyte-endothelium interaction” is currently the most credible.
Activated endothelium, leukocytes, mast cells, macrophages, fibroblast, target the extracellular matrix as well as parenchymal cells and produce a spectrum of inflammatory mediators and metabolites, cell membrane adhesion molecules, prothrombotic receptors, growth factors, and chemotactic agents. The inflammatory cascade in chronic venous insufficiency serves on one hand as a tissue repair mechanism but with resulting valvular incompetence may favor further inflammation which leads to varicosities and venous stasis and ultimately the occurrence of ulcers.
At the level of microcirculation: Hyperpressure at the capillary level induces capillary leakage allowing the accumulation of fluids, protein, and red blood cells in the interstitial space, forming edema.
Red blood cell degradation products and protein extravasations are the initial inflammatory signals that result in leukocyte migration into the interstitial space.
A cascade of pathologic events occurs during leukocyte migration into the dermis and the end product is intense dermal fibrosis and tissue remodeling leading to skin changes and finally to open ulceration.
So how do symptoms occur at the early beginning of the disease?
It is thought that the cascade of inflammation that follows activation of the venous endothelium after its interaction with leukocytes induces the release of abundant biochemical mediators that are presumed responsible for stimulating the sensory venous nerve extremities of C fibers present in the venous wall, relaying venous pain.
These C fiber extremities are believed to act as nociceptors (C nociceptors), which are primarily sensitive to chemical mediators.
The early inflammation associated with changes in the venous valves and wall can thus explain why patients suffer from pain from the earliest stages of the disease process.
NEJM review article added on the previous theories abut chronic venous disease:
CVD is now considered as an acquired inflammatory disease that should be treated as early as possible with a drug that is capable of preventing venous hypertension, reflux and inflammation.
Daflon 500mg was referenced in the NEJM publication as a treatment to inhibit inflammation.
