Molar Uprighting for Implant
Molar Uprighting for Implant samer kareem 11,170 Views • 2 years ago

Aim: To detail two different clinical protocols and case studies using mini-implant anchorage developed to respond to certain clinical conditions. Methods: Two clinical protocols are described to upright mesially tilted mandibular molars. In the first protocol, a single mini-implant is inserted distally to the molar to be uprighted, and an elastic traction chain is applied to the tooth. In the second clinical approach, two mini-implants are inserted mesially. A screw-suspended TMA sectional archwire is applied (Derton-Perini technique). Two cases, descriptive of the two different treatment protocols, are described. In the first case, the mandibular right second premolar was missing and the adjacent first molar needed to be uprighted. A single screw was inserted distally to the first molar, and an elastic chain was applied. In the second case, the mandibular left second molar was missing and the third molar needed to be uprighted. Two mini-implants were inserted mesially and a fully screw-supported sectional archwire was used to upright and bodily mesialize the third molar. Results: Both uprighting approaches uprighted the molar axis without loss of anchorage. Conclusion: The two approaches to mandibular molar uprighting, developed as rational responses to different clinical cases, were both found to be effective.

Devastating Consequences of Tooth Loss
Devastating Consequences of Tooth Loss samer kareem 10,354 Views • 2 years ago

Tooth loss can make you look older. When you lose a tooth and don’t replace it with a dental implant, you risk the chance of jawbone loss. Normally, your tooth root stimulates the continued growth and health of your jawbone. Dental implants mirror your natural tooth root and keep your jawbone healthy.

Medulloblastoma Brain Tumor Surgery
Medulloblastoma Brain Tumor Surgery samer kareem 2,575 Views • 2 years ago

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

Removes HIV-1 DNA From Human Cells
Removes HIV-1 DNA From Human Cells samer kareem 5,845 Views • 2 years ago

Scientists have developed a gene editing technique which targets HIV-1 DNA. Through the technique, scientists successfully edited the virus out the genome in human cells; their study also showed the technique can prevent viral replication in cleared cells. Using CRISPR/Cas9 gene editing, the team tested patient cells grown in a lab which were no longer susceptible to HIV infection.

Developmental Dysplasia of the Hip SurgicalTreatment
Developmental Dysplasia of the Hip SurgicalTreatment samer kareem 4,249 Views • 2 years ago

The definition of DDH is not universally agreed upon. Typically, the term DDH is used in referring to patients who are born with dislocation or instability of the hip, which may then result in hip dysplasia. More broadly, DDH may be defined simply as abnormal growth of the hip. Abnormal development of the hip includes the osseous structures, such as the acetabulum and the proximal femur, as well as the labrum, capsule, and other soft tissues. This condition may occur at any time, from conception to skeletal maturity. The author prefers to use the term hip dysplasia, considering it both simpler and more accurate. Internationally, this disorder is still referred to as congenital dislocation of the hip.

Understanding COPD
Understanding COPD samer kareem 2,398 Views • 2 years ago

COPD stands for chronic obstructive pulmonary (lung) disease. COPD is a term applied to a family of diseases that includes emphysema, chronic bronchitis, and emphysema due to alpha-1 antitrypsin deficiency. COPD usually progresses gradually, causing limited airflow in and out of the lungs. COPD adds to the work of the heart. Diseased lungs might reduce the amount of oxygen that goes to the blood. High blood pressure in blood vessels from the heart to the lungs makes it difficult for the heart to pump. Lung disease can also cause the body to produce too many red blood cells, which might make the blood thicker and harder to pump.

Questions about penile implantation surgery.
Questions about penile implantation surgery. samer kareem 7,669 Views • 2 years ago

The inflatable penile prosthesis consists of two attached cylinders -- a reservoir and a pump -- which are placed surgically in the body. The two cylinders are inserted in the penis and connected by tubing to a separate reservoir of saline. The reservoir is implanted under the rectus muscles in the lower abdomen. A pump is also connected to the system and sits under the loose skin of the scrotal sac, between the testicles. This penile prosthesis is referred to as a 3-piece inflatable penile prosthesis, due to the three different components. A 2-piece inflatable penile prosthesis consists of only two components: the attached cylinders and the combined reservoir and pump unit. Instead of the reservoir being placed behind the groin, it is combined with the pump into one housing unit that fits comfortably within the scrotum. The advantage of a 2-piece prosthesis in that the surgery is shorter and less complicated and there is no device parts in the abdomen. The disadvantage of the 2-piece prosthesis is that the smaller reservoir may not result in adequate erections in some men. To inflate the prosthesis, the man presses on the pump. The pump transfers saline from the reservoir to the cylinders in the penis, inflating them and causing an erection. Pressing on a deflation valve at the base of the pump returns the fluid to the reservoir, deflating the penis and returning it to the normal flaccid state.

Stab heart closing the pericardium,leaving a small window

Pericardial window is used diagnostically and, more often, therapeutically for drainage of accumulated pericardial fluid (a condition that most often occurs after cardiac surgery but has many other possible causes). The pericardium envelops the heart like a cocoon; its cardiac filling can be impaired when this cavity fills with excess fluid. When the limited space between the noncompliant pericardium and heart is acutely filled with blood or fluid, cardiac compression and tamponade may result. Pericardial window in combination with systemic chemotherapy may also prevent accumulation of large fluid volumes in patients with neoplastic pericardial disease. [1, 2] Indications The following are indications for a pericardial window [6] : Symptomatic pericardial effusions Asymptomatic pericardial effusions that warrant a pericardial window for diagnosis Hemodynamically stable patients with an undiagnosed pericardial effusion (a thoracoscopic approach is ideal) Coexisting pericardial, pleural, or pulmonary pathology that requires diagnosis or therapy (a thoracoscopic approach is ideal) Known benign effusions that reaccumulate after aspiration Drainage of a purulent pericardial effusion Early fungal or tuberculous pericarditis in which resection of the pericardium is required to prevent future pericardial constriction Use as part of the mediastinal debridement, in patients with descending mediastinitis
