Is oncology the right choice for you? samer kareem 1,493 Views • 2 years ago

What combines research opportunities, intellectual challenge, and international collaboration in the study of a disease which affects many organs of the body and all sectors of society? And demands that specialists from many different backgrounds work together to crack sometimes intractable problems? It is, of course, oncology. As a career choice, it's demanding; it takes passion coupled with a willingness to put in the hours and to learn how to discuss death honestly and sensitively. But for the right person, it can be immensely rewarding.

Bovine Respiratory Disease
Bovine Respiratory Disease samer kareem 1,246 Views • 2 years ago

Bovine respiratory disease (BRD) has a multifactorial etiology and develops as a result of complex interactions between environmental factors, host factors, and pathogens. Environmental factors (eg, weaning, transport, commingling, crowding, inclement weather, dust, and inadequate ventilation) serve as stressors that adversely affect the immune and nonimmune defense mechanisms of the host. In addition, certain environmental factors (eg, crowding and inadequate ventilation) can enhance the transmission of infectious agents among animals. Many infectious agents have been associated with BRD. An initial pathogen (eg, a virus) may alter the animal’s defense mechanisms, allowing colonization of the lower respiratory tract by bacteria.

Cervical Disc Surgical Technique
Cervical Disc Surgical Technique samer kareem 1,304 Views • 2 years ago

Patients are generally placed in a supine position with the head in an extended position. As noted above, Gardner-Wells tongs can be used for additional cervical traction. The hands can also be tied downward to increase the operative exposure. Once the surgical site is properly prepared with cleansing material, the appropriate surgical level is identified with intraoperative radiographs. A scalpel is used to make a linear longitudinal incision just medial to the body of the sternocleidomastoid muscle. The incision is made long enough to include at least 2 vertebral levels if a 1-level discectomy is being performed. Alternatively, transverse skin incisions over the targeted vertebral level can also be performed. The platysmal muscle is identified and incised. The platysmal incision can be extended if a multilevel decompression is the surgical aim. Extensive subplatysmal dissection is performed to reduce retraction injury.

Abscess Drainage
Abscess Drainage samer kareem 1,556 Views • 2 years ago

An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).

Multiple Myeloma Mechanism of Action
Multiple Myeloma Mechanism of Action samer kareem 1,502 Views • 2 years ago

The pathobiology of MM is complex and the root underlying cause of myeloma is the multistep genetic changes in the postgerminal center B cell. In addition, the bone marrow microenvironment plays a crucial role.[2] The interaction between myeloma cells and the microenvironment is mediated through adhesive interactions via cell-surface receptors, paracrine loops involving several cytokines, such as IL-6, VEGF and IL-10, and suppression of cell-mediated immunity.[2–4] IMiDs modulate many of these interactions leading to decreased myeloma cell growth and survival. Thalidomide was the first IMiD introduced to treat MM. It was initially synthesized in Germany in the late 1950s to treat insomnia and morning sickness. It was withdrawn from the market in 1961 because of its teratogenic effects. Its immunomodulatory properties were realized when it was observed to improve erythema nodosum leprosum, a painful immunologic reaction of leprosy, leading to its approval by the FDA in 1998 with tight prescribing and marketing regulations. Subsequent research showed the diverse mechanism of action of thalidomide including its immunomodulatory effect by inhibition of de novo IgM antibody synthesis,[5] modulation of the T-cell subset by increasing the T-helper cells, inhibitory effects on the TNF-α and antiangiogenic activity leading to its use in MM. Significantly higher response rates in combination with dexamethasone led to its approval in the treatment of newly diagnosed MM in 2006. Lenalidomide, a second-generation IMiD, was developed from the structural backbone of the thalidomide molecule by the addition of an amino group (NH2-) at position 4 of the phthaloyl ring and removal of the carbonyl group (C = O) of the 4-amino-substituted phthaloyl ring (Table 1).[6] In addition to immunomodulatory effects, other mechanisms of action have been described such as direct cytotoxicity via induction of apoptosis, inhibition of cell adhesion molecules and inhibition of growth signals that promote bone marrow angiogenesis

In this video Erin K, a tubal reversal patient, explains the symptoms she experienced while suffering from Post Tubal Ligation Syndrome (PTLS). After having tubal reversal surgery her symptoms were relieved. Although numerous women suffer from adverse symptoms after having a tubal ligation, many physicians do not believe PTLS exists. In an ongoing study of over 300 patients reporting Post Tubal Ligation symptoms more than 90% have found relief after tubal reversal at Chapel Hill Tubal Reversal Center.
