Varicose veins are abnormally enlarged superficial veins that can cause symptoms like aching or throbbing. They are caused by factors that increase pressure in the veins like prolonged standing, obesity, pregnancy, or genetics. Varicose veins are diagnosed through physical examination and sometimes ultrasound. Treatment depends on severity but may include compression stockings, minimally invasive procedures to close veins, or small incision surgery. Lifestyle changes like exercise and weight loss can help prevent varicose veins.
The document discusses plastic surgery, its benefits and risks. It interviews a plastic surgeon, Dr. Ali Manafi, about his experience and views on plastic surgery. He notes that the most important factors for a successful procedure are choosing the right patient and surgical technique. While cosmetic surgery can improve self-esteem if done correctly, psychological disorders often underlie the desire for it and surgery will not satisfy patients with body dysmorphic disorder. Rhinoplasty is currently the most common cosmetic procedure performed.

The document discusses prophylaxis for deep vein thrombosis (DVT). It defines DVT and describes its pathophysiology. Risk factors for DVT include surgery, immobilization, old age, cancer, and inherited or acquired thrombophilias. Without prophylaxis, DVT can occur in 40-60% of major orthopedic surgeries and lead to pulmonary embolism. Methods of prophylaxis include mechanical methods like mobilization and compression devices as well as pharmacological methods like low molecular weight heparin, factor Xa inhibitors, and vitamin K antagonists. Guidelines recommend different prophylaxis options based on surgery type and patient risk factors
The FDA issued an update on serious complications associated with transvaginal placement of surgical mesh for pelvic organ prolapse. Based on reports from 2008-2010, complications were found to not be rare and included mesh erosion, pain, infection and organ perforation. The literature review found erosion to be the most common mesh-related complication and that mesh contraction can cause vaginal pain and tightening. The FDA recommends considering non-mesh alternatives first due to risks and that mesh placement requires specialized training. Surgeons should discuss risks and benefits of all options with patients.
Varicose vein disease, which affects 30 million Americans, is caused by damaged valves in the leg veins that allow blood to pool instead of returning to the heart. Risk factors include age, family history, jobs requiring long periods of standing or sitting, obesity, and pregnancy. Symptoms include aching, throbbing, fatigue, and heaviness in the legs that worsen throughout the day. Left untreated, varicose veins can cause skin damage and ulcers. While compression stockings provide some relief, varicose veins will progress without treatment. Modern treatments like vein ablation use laser or radiofrequency energy through a small catheter to seal the damaged vein shut, improving symptoms with little recovery time and no scarring.

1. Thrombosis is the formation of a blood clot within a blood vessel which can prevent normal blood flow. It is a leading cause of death in western countries.
2. When clots form in veins they cause deep vein thrombosis and pulmonary embolisms, while arterial clots cause heart attacks and strokes. Those at highest risk include those with atrial fibrillation, history of stroke, deep vein thrombosis, pulmonary embolism, or those having certain surgeries.
3. Anticoagulants like heparin, warfarin, and newer oral anticoagulants (NOACs) are used to prevent clotting and treat existing clots.
Vein illumination devices are used to enhance the visibility of veins and make venipuncture procedures easier. They work by using infrared light, which is absorbed by hemoglobin in the blood, making the veins appear brighter against the skin. This helps medical professionals more quickly and easily locate veins. While they can be expensive, ranging from $600 to over $30,000, vein illumination devices provide benefits like reducing multiple needle sticks, lowering patient discomfort, and improving satisfaction. They are particularly useful for patients with difficult venous access.
1) Laparoscopic hernia repair is beneficial compared to open surgery because it causes minimal pain and allows patients to return to normal activities much quicker by avoiding large incisions and muscle cutting.
2) During laparoscopic hernia repair, small incisions are made and surgical tools and a camera are inserted to place a mesh over the defect from inside the abdomen, putting less strain on muscles.
3) Studies show laparoscopic hernia repair reduces post-operative pain and recovery time and has extremely low recurrence rates compared to open surgery due to how the mesh is securely placed from inside.

Heart Valves and Heart Sounds -Congenital & valvular heart disease.pdfMedicoseAcademics
This presentation, authored by Dr. Faiza, Assistant Professor of Physiology at CIMS Multan, delivers an in-depth analysis of heart valves, heart sounds, valvular heart diseases, and congenital heart defects. It begins by distinguishing between normal and abnormal heart sounds, elucidating the timing and causes of the four heart sounds—S1, S2, S3, and S4—and their clinical significance. Detailed explanations are provided on the auscultation sounds that define conditions such as mitral stenosis, mitral insufficiency, aortic stenosis, and aortic insufficiency, with a focus on how these pathological changes affect cardiac mechanics and blood pressure.
The presentation delves into abnormal heart sounds, known as murmurs, categorizing them by their causes, which include valvular lesions, rheumatic fever, aging, congenital heart diseases, viral infections during pregnancy, and hereditary factors. It explores the various types of murmurs, their timing within the cardiac cycle, and their association with specific valvular heart diseases such as stenosis and regurgitation. The intricate relationship between systolic and diastolic murmurs and conditions like anemia and ventricular septal defects is also highlighted.
Further, the presentation covers the pathophysiology of congenital heart diseases, offering a comprehensive review of conditions such as Tetralogy of Fallot and Patent Ductus Arteriosus. It explains the mechanisms of these diseases, their impact on cardiac function, and the clinical manifestations observed in affected individuals. The physiological adjustments of the circulatory system during exercise in patients with valvular lesions are discussed, emphasizing the reduced cardiac reserve and the risk of acute pulmonary edema.
Special attention is given to the compensatory mechanisms of the heart in response to valvular diseases, including the development of concentric and eccentric hypertrophy, increased venous return, and the eventual progression to heart failure. The presentation also examines rheumatic valvular lesions, aging-related aortic stenosis, and the specific challenges posed by these conditions, such as reduced stroke volume and increased metabolic demand.
This thorough exploration of heart sounds, valvular diseases, and congenital defects is designed to enhance understanding and clinical acumen, making it a valuable resource for medical students, healthcare professionals, and educators in the field of cardiology and physiology.

Osvaldo Bernardo Muchanga- MALE CIRCUMCISION, ITS Vs SOCIOCULTURAL BELIEFS (C...Osvaldo Bernardo Muchanga
MALE CIRCUMCISION consists of the surgical act of removing the foreskin (skin that covers the glans of the penis), leaving the glans more prominent and better cleanable.
MALE CIRCUMCISION itself has medical as well as sociocultural implications, as it has been proven to be an act that can minimize SEXUALLY TRANSMITTED INFECTIONS (STIs), especially HIV, but it also represents the SOCIOCULTURAL IDENTITY of some people, respectively.
Now, in a SERO-EPIDEMIOLOGICAL PROFILE like that of Mozambique where the prevalence of HIV is around 12.5% which corresponds to approximately 2 million people living with HIV, where the province of GAZA is the most seroprevalent with a positivity rate of 21% (INSIDA, 2021), it is extremely necessary to THOROUGHLY scrutinize all possibilities for preventing or minimizing the spread of HIV and other STIs.
General Endocrinology and mechanism of action of hormonesMedicoseAcademics
This presentation, given by Dr. Faiza, Assistant Professor of Physiology, delves into the foundational concepts of general endocrinology. It covers the various types of chemical messengers in the body, including neuroendocrine hormones, neurotransmitters, cytokines, and traditional hormones. Dr. Faiza explains how these messengers are secreted and their modes of action, distinguishing between autocrine, paracrine, and endocrine effects.
The presentation provides detailed examples of glands and specialized cells involved in hormone secretion, such as the pituitary gland, pancreas, parathyroid gland, adrenal medulla, thyroid gland, adrenal cortex, ovaries, and testis. It outlines the special features of hormones, differentiating between peptides and proteins based on their amino acid composition.
Key principles of endocrinology are discussed, including hormone secretion in response to stimuli, the duration of hormone action, hormone concentrations in the blood, and secretion rates. Dr. Faiza highlights the importance of feedback control in hormone secretion, the occurrence of hormonal surges due to positive feedback, and the role of the suprachiasmatic nucleus (SCN) of the hypothalamus as the master clock regulating rhythmic patterns in biological clocks of neuroendocrine cells and endocrine glands.
The presentation also addresses the metabolic clearance of hormones from the blood, explaining the mechanisms involved, such as metabolic destruction by tissues, binding with tissues, and excretion by the liver and kidneys. The differences in half-life between hydrophilic and hydrophobic hormones are explored.
The mechanism of hormone action is thoroughly covered, detailing hormone receptors located on the cell membrane, in the cell cytoplasm, and in the cell nucleus. The processes of upregulation and downregulation of receptors are explained, along with various types of hormone receptors, including ligand-gated ion channels, G protein–linked hormone receptors, and enzyme-linked hormone receptors. The presentation elaborates on second messenger systems such as adenylyl cyclase, cell membrane phospholipid systems, and calcium-calmodulin linked systems.
Finally, the methods for measuring hormone concentrations in the blood, such as radioimmunoassay and enzyme-linked immunosorbent assays (ELISA), are discussed, providing a comprehensive understanding of the tools used in endocrinology research and clinical practice.

Harvester, new varicose veins treatment
Sun, 23 Dec 2007 18:20:08
By Patricia Khashayar, MD., Press TV, Tehran
Board certified vascular surgeon Dr. Heshmat Majlessi is a fellow of the American College of
Surgeons and International College of Surgeons and the director of Park Avenue Vein Center.
He finished his surgical residency in NY Medical College. Following his training in open heart
surgery and vascular surgery he came in contact with Professor George Fegan in England who
was the father of non-surgical treatment of varicose veins. Since then he has confined his
practice to varicose veins.
He has several inventions and patents under his name (all medical in nature); the latest one is
for permanent varicose veins treatment.
Q. What attracted you to this field initially?
A. I received training as a vascular surgeon. For many years, the field of varicose veins was
neglected. I chose this field 20 years ago. Recently many young doctors have been showing
interest in this field.
Q. Can you please explain what varicose veins are?
A. There are hundreds of small superficial veins under the skin in the legs and thighs. These tiny
veins become larger and sometimes twisted, mostly due to the pressure from so called leaks in
different part of the legs (perforators) and result in varicose veins. These in turn produce many
tiny spider veins which are not attractive.
Q. Why are varicose veins considered to be more than a cosmetic problem?
A. Varicose veins can cause pain, swelling, cramp, clots (phlebitis), ulcers and bleeding.
Q. The general belief is that varicose veins are limited to the legs. Could you tell us which organs
are frequently affected by this syndrome?
A. Varicose veins are mainly seen in the legs but they can also develop in other parts of the body
like the intestine (stomach, esophagus). Varicose veins of the rectum are called hemorrhoids.
Q. Why are women more prone to developing varicose veins?
A. Pregnancy is the most important cause of varicose veins; therefore women are affected about
5 times more than men.
Q. What are the major risk factors for developing varicose veins?
A. Pregnancy, family history, weight, being on the feet for long periods of time and possibly
hormones like progesterone.
Q. What happens if a person does not seek treatment for the syndrome?
http://www.presstv.ir/pop/print.aspx?id=36096 7/15/2008
2. Press TV Print Page 2 of 3
A. As I mentioned before, it will result in several medical complications. All the pain and swelling
disappears after treatment. Getting rid of the unpleasant looking veins is also very important for
many patients.
Q. What are the available treatment methods?
A. In the old treatment which is still practiced today, the doctor makes numerous incisions over
the veins and removes them under anesthesia.
Another technique which has become common over the past five years is to use laser or a hot
wire to burn the saphenous vein in the thigh (electrofrequency).
The Harvester technique which uses my device is the latest development in this field. It is
intended to permanently eliminate varicose veins and even spiders by closing ALL responsible
leaks. The method has resulted in a near perfect leg in 99% of the patients.
Q. Could you tell us more about your treatment method?
A. The patented Harvester technique is a 15 minutes local procedure which completely eliminates
the large leaks responsible for the varicose veins and spiders.
The procedure does not require any major anesthesia or disability. Patients can immediately fly
back to their country of origin after the treatment. They will need a couple more visits to treat all
the tiny leftover veins and spiders.
Q. What are the advantages of the Harvesting technique over regular treatments?
A. Lack of severe pain and disability, no need for major anesthesia and excellent cosmetic
outcome.
Q. What are the complications of this method?
A. The common side effect is slight bruising in the inner thigh which disappears after a few days.
We have not had any reported infections or bleeding.
Q. What is its prognosis?
A. The present varicose veins disappear permanently in all patients. We recommend the patients
to follow up every couple of years in order to treat any developed tiny veins or spiders before
they become bigger.
Q. Are there any criteria for selecting the patients who benefit most from this method? What are
the success rate predicting factors?
A. All patients with superficial varicose veins are candidates for Harvester technique. The only
exceptions are patients taking blood thinner coumadin.
Q. How many patients have benefited from this therapy so far?
A. Over 1500 patients
Q. What were some of the most rewarding and/or challenging moments you experienced in this
project?
A. For me seeing a patient's reaction after the operation is the most rewarding moment. Many of
