Thyroid Disease During Pregnancy samer kareem 2,349 Views • 2 years ago

Uncontrolled hyperthyroidism during pregnancy can lead to serious health problems in the mother and the unborn baby. During pregnancy, mild hyperthyroidism does not require treatment. More severe hyperthyroidism is treated with antithyroid medications, which act by interfering with thyroid hormone production.

Perineal Repair
Perineal Repair samer kareem 15,295 Views • 2 years ago

Perineal repair after episiotomy or spontaneous obstetric laceration is one of the most common surgical procedures. Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.3–5 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. This article discusses a repair method that emphasizes anatomic detail, with the expectation that an anatomically correct perineal repair may result in a better long-term functional outcome.

Subcuticular Suture
Subcuticular Suture samer kareem 18,764 Views • 2 years ago

The two biggest considerations when choosing a suture are the location and tension of the wound. Other important considerations are tensile strength, knot strength, handling, and tissue reactivity. Sutures are divided into two major groups: Absorbable – lose the majority of their tensile strength in less than 60 days. They are generally used for buried sutures and do not require removal. Non-absorbable – maintain the majority of their tensile strength for more than 60 days. They are generally used for skin surface sutures and do require removal postoperatively. Suture needles also come in a variety of shapes and sizes. Curved needles are almost exclusively used in dermatological surgery. Cutting needles move through the tissue more easily and may have their primary cutting edge on the inside of the curve (conventional cutting) or outside of the curve (reverse cutting). The benefit of reverse cutting is that the tapered puncture left by the suture is directed away from the wound edge and therefore tissue tearing is less common. Non-cutting round needles cause even less tissue tearing and may be especially useful in delicate areas and fascia.

Colon and Rectal Cancer samer kareem 10,115 Views • 2 years ago

Colorectal cancer (also known as colon cancer, rectal cancer or bowel cancer) is the development of cancer in the colon or rectum (parts of the large intestine). It is due to the abnormal growth of cells that have the ability to invade or spread to other parts of the body. People with HNPCC tend to develop colon cancer before age 50. Familial adenomatous polyposis (FAP). FAP is a rare disorder that causes you to develop thousands of polyps in the lining of your colon and rectum. People with untreated FAP have a greatly increased risk of developing colon cancer before age 40.

Why Do You Get Itchy?
Why Do You Get Itchy? samer kareem 2,300 Views • 2 years ago

Pruritis is itchy skin that makes you want to scratch. It can be caused by many things. Normally, itchy skin isn't serious, but it can make you uncomfortable. Sometimes, itchy skin is caused by a serious medical condition. It can occur in association with a primary rash (e.g. dermatitis) or may occur because of hypersensitive nerves in the skin (neuropathic pruritus). ... Scratching a localised itch may lead to lichen simplex, prurigo or prurigo nodularis. Systemic causes of pruritus. Sytemic diseases may cause generalised pruritus.

Breast Lumps
Breast Lumps samer kareem 5,162 Views • 2 years ago

Breast lumps facts Breast lumps can be caused by infections, injuries, non-cancerous growths, and cancer. Breast cancer usually causes no pain in the breast. The symptoms of breast cancer include painless breast lumps, nipple discharge, and inflammation of the skin of the breast. The chances that a particular breast lump could be cancerous depends on many factors, including past medical history, physical examination, as well as genetic and other risk factors. The only way to be certain that a lump is not cancerous is to have a tissue sampling (biopsy). There are several ways to do the biopsy. The treatment of a breast lump depends on its cause.

Robotic Partial Nephrectomy
Robotic Partial Nephrectomy samer kareem 2,311 Views • 2 years ago

The robotic approach to renal surgery, particularly partial nephrectomy, has some inherent challenges, and some familiarity with the da Vinci robotic system is necessary. The surgeon must gain an understanding of the robotic arm movements and range of motion, especially in relation to the clutch and camera. The advent of robotically assisted prostatectomy in 2001 [23] paved the way for widespread accessibility to the da Vinci robotic unit and its application to renal surgery. Since that time, at least one multi-institutional survey has demonstrated superiority of the robotic approach when compared to laparoscopic for outcomes of blood loss, hospital stay and a substantially shorter warm ischemia time, while maintaining equivalence in positive margin rate, operative time and complications. [11] A transperitoneal approach is most commonly used. Prior abdominal operation is not necessarily a contraindication to this procedure, but access should be approached with regard for previous operation(s) by an experienced team.

Tummy Tuck Surgery
Tummy Tuck Surgery Scott 3,610 Views • 2 years ago

Tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating an abdominal profile that is smoother and firmer. A flat and well-toned abdomen is something many of us strive for through exercise and weight control. Sometimes these methods cannot achieve our goals. Even individuals of otherwise normal body weight and proportion can develop an abdomen that protrudes or is loose and sagging. The most common causes of this include: Aging Heredity Pregnancy Prior surgery Significant fluctuations in weight What tummy tuck surgery can't do A tummy tuck is not a substitute for weight loss or an appropriate exercise program. Although the results of a tummy tuck are technically permanent, the positive outcome can be greatly diminished by significant fluctuations in your weight. For this reason, individuals who are planning substantial weight loss or women who may be considering future pregnancies would be advised to postpone a tummy tuck. A tummy tuck cannot correct stretch marks, although these may be removed or somewhat improved if they are located on the areas of excess skin that will be excised.

Neonatal Resuscitation
Neonatal Resuscitation samer kareem 28,055 Views • 2 years ago

The following guidelines are an interpretation of the evidence presented in the 2010 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations1). They apply primarily to newly born infants undergoing transition from intrauterine to extrauterine life, but the recommendations are also applicable to neonates who have completed perinatal transition and require resuscitation during the first few weeks to months following birth. Practitioners who resuscitate infants at birth or at any time during the initial hospital admission should consider following these guidelines. For the purposes of these guidelines, the terms newborn and neonate are intended to apply to any infant during the initial hospitalization. The term newly born is intended to apply specifically to an infant at the time of birth.

Digoxin is derived from the leaves of a digitalis plant. Digoxin helps make the heart beat stronger and with a more regular rhythm. Digoxin is also used to treat atrial fibrillation, a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart).

Familial Hypocalciuric Hypercalcemia
Familial Hypocalciuric Hypercalcemia samer kareem 4,346 Views • 2 years ago

There are 3 genetic types of FHH based on chromosome location. FHH type 1 accounts for 65% of cases and is due to inactivating mutations in the CASR gene, localized to 3q21.1. This gene encodes the calcium-sensing receptor (CaSR). Loss of CaSR function results in a reduction in the sensitivity of parathyroid and renal cells to calcium levels so hypercalcemia is perceived as normal. The other 35% have either a mutation GNA11 (19p13.3) seen in FHH type 2 or AP2S1 (19q13.2-q13.3) seen in FHH type 3 (see these terms) or in genes not yet discovered. FHH is rarely caused by auto-antibodies against CaSR in those without a mutation.
