Breast Cancer
Breast Cancer samer kareem 1,388 Views • 3 years ago

Breast cancer usually starts off in the inner lining of milk ducts or the lobules that supply them with milk. A malignant tumor can spread to other parts of the body. A breast cancer that started off in the lobules is known as lobular carcinoma, while one that developed from the ducts is called ductal carcinoma. The vast majority of breast cancer cases occur in females. This article focuses on breast cancer in women. We also have an article about male breast cancer. Breast cancer is the most common invasive cancer in females worldwide. It accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide, including both males and females, are from breast cancer. Breast cancer rates are much higher in developed nations compared to developing ones. There are several reasons for this, with possibly life-expectancy being one of the key factors - breast cancer is more common in elderly women; women in the richest countries live much longer than those in the poorest nations. The different lifestyles and eating habits of females in rich and poor countries are also contributory factors, experts believe. According to the National Cancer Institute, 232,340 female breast cancers and 2,240 male breast cancers are reported in the USA each year, as well as about 39,620 deaths caused by the disease.

‘Surgeon’ struggles to remove live snake from woman’s ear in viral video
‘Surgeon’ struggles to remove live snake from woman’s ear in viral video Scott 222 Views • 3 years ago

Thought a snake in your boot was bad? That old 19th-century idiom is nothing compared to one in your ear.

Shocking footage captured the alleged moment that a “surgeon” tried to remove a live snake that infiltrated a woman’s ear. Video of the herpetological surgery has racked up more than 125,000 views as viewers speculate whether or not the squirm-inducing footage is authentic.

“The snake has gone in the ear,” reads the caption to the bizarre Facebook clip, which was posted Sept. 1 by an India-based social media star named Chandan Singh to his 20,126 followers. However, it’s unclear where, when or how this unfortunate event transpired, local outlet the Economic Times reported.

In the nearly four-minute clip, an alleged medical practitioner can be seen using tweezers in a desperate attempt to extract a black and yellow serpent that’s peeking its head out from a female patient’s ear.

CHICKEN POX
CHICKEN POX samer kareem 1,641 Views • 3 years ago

Chickenpox (varicella) is a viral infection that causes an itchy rash with small, fluid-filled blisters. Chickenpox is highly contagious to people who haven't had the disease or been vaccinated against it. Before routine chickenpox vaccination, virtually all people had been infected by the time they reached adulthood, sometimes with serious complications. Today, the number of cases and hospitalizations is down dramatically. For most people, chickenpox is a mild disease. Still, it's better to get vaccinated. The chickenpox vaccine is a safe, effective way to prevent chickenpox and its possible complications.

Venipuncture Technique
Venipuncture Technique Mohamed Ibrahim 10,842 Views • 3 years ago

The venipuncture procedure is complex, requiring both knowledge and skill to perform. Each phlebotomist generally establishes a routine that is comfortable for her or him. Several essential steps are required for every successful collection procedure: Identify the patient. Assess the patient's physical disposition (i.e. diet, exercise, stress, basal state). Check the requisition form for requested tests, patient information, and any special requirements. Select a suitable site for venipuncture. Prepare the equipment, the patient and the puncture site. Perform the venipuncture. Collect the sample in the appropriate container. Recognize complications associated with the phlebotomy procedure. Assess the need for sample recollection and/or rejection. Label the collection tubes at the bedside or drawing area. Promptly send the specimens with the requisition to the laboratory.

Premature Ejaculation - Causes and how to Avoid it
Premature Ejaculation - Causes and how to Avoid it samer kareem 44,887 Views • 3 years ago

Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than he or his partner would like. Premature ejaculation is a common sexual complaint. Estimates vary, but as many as 1 out of 3 men say they experience this problem at some time. As long as it happens infrequently, it's not cause for concern. However, you may meet the diagnostic criteria for premature ejaculation if you: Always or nearly always ejaculate within one minute of penetration Are unable to delay ejaculation during intercourse all or nearly all of the time Feel distressed and frustrated, and tend to avoid sexual intimacy as a result Both psychological and biological factors can play a role in premature ejaculation. Although many men feel embarrassed to talk about it, premature ejaculation is a common and treatable condition. Medications, counseling and sexual techniques that delay ejaculation — or a combination of these — can help improve sex for you and your partner.

Examination of the Thyroid - Clinical Examination
Examination of the Thyroid - Clinical Examination DrPhil 173 Views • 3 years ago

The thyroid gland lies in the midline of the anterior neck, just caudal to the thyroid cartilage. To inspect the thyroid gland, the examiner stands in front of the patient. The examiner asks the seated patient to dorsiflex (extend) the neck and swallow a sip of water. Minor enlargement of the gland may only become apparent on inspection in this position. Palpation of the thyroid gland is typically performed with the examiner standing behind the patient. Both lobes and the isthmus of the thyroid gland should be palpated for any nodules or diffuse enlargement. Mobility of the thyroid gland with swallowing should be assessed with palpation. Nodules arising from the thyroid gland typically move with swallowing. A hard, fixed thyroid gland could indicate malignancy. If a central nodule is identified, the patient is asked to protrude the tongue. Upward movement of the central nodule on protrusion of the tongue indicates a thyroglossal cyst. Auscultation is performed at the superior poles of bilateral lobes as this is where the superior thyroid artery is most superficial and bifurcates into its terminal branches. A bilateral bruit over the superior poles suggests Graves disease. Examination of the thyroid gland is completed by palpating the regional cervical lymph nodes for any enlargement.
