Understanding multiple sclerosis and what it does to the body
Understanding multiple sclerosis and what it does to the body samer kareem 5,559 Views • 2 years ago

Multiple sclerosis (MS) is a disease of the central nervous system estimated to affect 2.3 million people worldwide. It is a chronic disease in which the immune system abnormally attacks the insulation and support around the nerve cells (myelin sheath) in the brain, spinal cord and optic nerves, causing inflammation and consequent damage. MS is a leading cause of non-traumatic disability in young people, usually striking between 20 and 40 years of age. There is no cure for MS, but research continues to better understand and treat the disease.

Sonographic Hematoma Guided resection of mammogram only visible breast cancer DrHouse 15,542 Views • 2 years ago

Excision of breast cancer that is visible only on mammogram. diagnosis is typically established on stereotactic biospy and excision is done with wire localization. This techniques involves localization by sonography of the hematoma that is left behind at the time of biopsy. It provides not only accu...rate location of the tumor but ensures adequate margins of excision.

Keratoderma Blennorrhagicum is a manifestation on the skin that appears in patients diagnosed with reactive arthritis (this condition was previously known as Reiter syndrome). The condition manifests itself by lesions that appear on the skin, initially on the palm of the hands and soles of the feet. The lesions have the tendency to spread, affecting other parts of the body, such as the scrotum, scalp or trunk. Because of their appearance, the lesions might be easily confused with the ones from psoriasis. Keratoderma blennorrhagicum is one of the symptoms that can be used for the clinical diagnosis of reactive arthritis.

Seizure
Seizure samer kareem 2,130 Views • 2 years ago

A seizure occurs when there’s abnormal electrical activity in the brain. Seizures may go virtually unnoticed. Or, in severe cases, they may produce a change or loss of consciousness and involuntary muscle spasms called convulsions. Seizures usually come on suddenly and vary in duration and severity. A seizure may be a one-time event, or you may have seizures repeatedly. Recurrent seizures are called epilepsy, or a seizure disorder. Less than one in 10 people who has a seizure develops epilepsy. Experts classify seizures into two general categories and many subtypes based on the pattern of the attack. Generalized seizures involve both sides of the brain from the start of the attack. Common subtypes include tonic-clonic (grand mal) and absence seizures (petit mal). Febrile and infantile spasms are two types of generalized seizures that occur almost exclusively in young children. Partial (or focal) seizures are the second major seizure type. These begin in a specific area of the brain and may be contained there. Or they may spread to the entire brain. With simple partial seizures, the person remains conscious. Complex partial seizures involve impaired consciousness. What Causes Seizures? Often the cause of a seizure is unknown. Many conditions can provoke seizures, including: Stroke Brain tumors Head injuries Electrolyte imbalance Very low blood sugar Repetitive sounds or flashing lights, such as in video games Medications, such as antipsychotics and some asthma drugs Withdrawal from medications, such as Xanax, narcotics, or alcohol Use of drugs such as cocaine and heroin Cancer Brain infections, such as meningitis

Posterior Elbow Dislocation Reduction
Posterior Elbow Dislocation Reduction samer kareem 1,948 Views • 2 years ago

Posterior dislocations with associated fractures, also known as complex posterior dislocations, often require open reduction and fixation (ORIF). These dislocations are often associated with significant ligamentous injury. In some cases, complex posterior elbow dislocations may be managed with closed reduction. Posterior elbow dislocations that are neglected, as is not uncommon in developing countries, can often be effectively treated with open reduction. [9] Delayed vascular compromise is an important complication after reduction. All patients should be observed for a period of approximately 2-3 hours after reduction. If no evidence of vascular compromise arises, patients can be sent home with appropriate follow-up and instructions to watch for further problems.

Partial Nephrectomy
Partial Nephrectomy Doctor 32,947 Views • 2 years ago

PURPOSE: Laparoscopic partial nephrectomy (LPN) is an alternative modality of treatment for small sized renal cell carcinoma. Robot assisted laparoscopic partial nephrectomy (RLPN) has also been performed with an advantage in repairing resected surface after tumor resection. We compare the periopera...

tive data of patients treated with laparoscopic partial nephrectomy with those of RLPN undertaken patients. MATERIAL AND METHOD: From September 2006 to April 2008, 22 patients were treated with LPN and 22 were RLPN. 3 arms were used for RLPN; camera was inserted through the 12mm, umbilical trocar port. The laparoscopic Bulldog clamp was used for the clamping of renal hilum. We retrospectively compared each group about tumor size, operation time, estimated blood loss, warm ischemic time and hospital stay. RESULT: Operation time of LPN was shorter than that of RLPN (p=0.033). Tumor size, estimated blood loss and hospital stay was not significant different in each group. No case had conversion to open surgery. 1 patient of RLPN group, however, had conversion to radical nephrectomy due to severe bleeding. CONCLUSION: RLPN was safe and feasible in small sized renal cell carcinoma. Warm ischemic time was reasonable and morbidity associated with RLPN was also low. RLPN LPN p-value Tumor Size (cm) 2.5 2.1 0.605 Op time (min) 169.3 140.8 0.033 EBL (ml) 243.2 213.2 0.878 Warm Ischemic Time (min) 29.2 26.4 0.237 Transfusion (%) 4.5 4.5 0.756 Hospital stay (day) 4.4 5.5 0.053

Upper Lip Tie Treatment
Upper Lip Tie Treatment samer kareem 1,417 Views • 2 years ago

Tongue and lip-tie are common causes of nipple pain, uneven breast drainage, slow weight gain and low milk supply. Many physicians do not properly assess for tongue or lip-tie or recognize their impact on the breastfeeding relationship, leaving babies vulnerable to early weaning. Ultrasound studies have shown that the tongue movements used by tongue-tied babies are qualitatively different from those used by by babies who are not tongue-tied. These movements are not as effective at removing milk from the breast and can cause significant pain and nipple damage. In these studies, tongue-tied babies also did not draw the nipple as deeply into the mouth as babies who were not tongue-tied.

HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,455 Views • 2 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.
