Cerebral Venous Sinus Thrombosis
Cerebral Venous Sinus Thrombosis samer kareem 5,782 Views • 2 years ago

Thrombosis of the venous channels in the brain is an uncommon cause of cerebral infarction relative to arterial disease, but it is an important consideration because of its potential morbidity. (See Prognosis.) Knowledge of the anatomy of the venous system is essential in evaluating patients with cerebral venous thrombosis (CVT), since symptoms associated with the condition are related to the area of thrombosis. For example, cerebral infarction may occur with cortical vein or sagittal sinus thrombosis secondary to tissue congestion with obstruction. (See Presentation.) Lateral sinus thrombosis may be associated with headache and a pseudotumor cerebri–like picture. Extension into the jugular bulb may cause jugular foramen syndrome, while cranial nerve palsies may be seen in cavernous sinus thrombosis as a compressive phenomenon. Cerebral hemorrhage also may be a presenting feature in patients with venous sinus thrombosis. (See Presentation.) Imaging procedures have led to easier recognition of venous sinus thrombosis (see the images below), offering the opportunity for early therapeutic measures. (See Workup.)

View Media Gallery The following guidelines for CVT have been provided by the American Heart Association and the American Stroke Association [1] : In patients with suspected CVT, routine blood studies consisting of a complete blood count, chemistry panel, prothrombin time, and activated partial thromboplastin time should be performed. Screening for potential prothrombotic conditions that may predispose a person to CVT (eg, use of contraceptives, underlying inflammatory disease, infectious process) is recommended in the initial clinical assessment. Testing for prothrombotic conditions (including protein C, protein S, or antithrombin deficiency), antiphospholipid syndrome, prothrombin G20210A mutation, and factor V Leiden can be beneficial for the management of patients with CVT. Testing for protein C, protein S, and antithrombin deficiency is generally indicated 2-4 weeks after completion of anticoagulation. There is a very limited value of testing in the acute setting or in patients taking warfarin. In patients with provoked CVT (associated with a transient risk factor), vitamin K antagonists may be continued for 3-6 months, with a target international normalized ratio of 2.0-3.0. In patients with unprovoked CVT, vitamin K antagonists may be continued for 6-12 months, with a target international normalized ratio of 2.0-3.0. For patients with recurrent CVT, venous thromboembolism (VTE) after CVT, or first CVT with severe thrombophilia (ie, homozygous prothrombin G20210A; homozygous factor V Leiden; deficiencies of protein C, protein S, or antithrombin; combined thrombophilia defects; or antiphospholipid syndrome), indefinite anticoagulation may be considered, with a target international normalized ratio of 2.0-3.0. For women with CVT during pregnancy, low-molecular-weight heparin (LMWH) in full anticoagulant doses should be continued throughout pregnancy, and LMWH or vitamin K antagonist with a target international normalized ratio of 2.0-3.0 should be continued for ≥6 weeks postpartum (for a total minimum duration of therapy of 6 months). It is reasonable to advise women with a history of CVT that future pregnancy is not contraindicated. Further investigations regarding the underlying cause and a formal consultation with a hematologist or maternal fetal medicine specialist are reasonable. It is reasonable to treat acute CVT during pregnancy with full-dose LMWH rather than unfractionated heparin. For women with a history of CVT, prophylaxis with LMWH during future pregnancies and the postpartum period is reasonable.

Though the risk of HIV transmission through oral sex is very low, but several factors might increase the risk, including sores in the mouth or vagina or on the penis, bleeding gums, having an oral contact with menstrual blood, and the presence of other sexually transmitted diseases. But still the risk is low. by the way better to think twice before having the Oralsex with strangers. because you are not safe 100%.

Majority of patients these days prefer PCNL ( Minimal Invasive Telescopic removal of kidney stones broken with lithoclast, removed through a button hole incision ). This patient with a big stone in the pelvis of the kidney wanted it open only so I did an open pyelolithotomy for this patient after a long time as I use to do it in routine in the past. Except for the long incision and scar as compared to PCNL the recovery time was the same and patient went home third day happily walking and eating.

Necrotizing Fasciitis
Necrotizing Fasciitis samer kareem 17,539 Views • 2 years ago

Two types of clinically distinct necrotizing fasciitis have been described. The most common form (type II) usually occurs in individuals with no concurrent medical illness. Many patients report a history of laceration, blunt trauma, or a surgical procedure as a predisposing factor. It is typically caused by group A Streptococcus (Streptococcus pyogenes). In contrast, type I is usually seen in patients with underlying diabetes and peripheral vascular disease. It is generally a polymicrobial infection; some commonly isolated organisms include Staphylococcus aureus, Bacteroides tragi/is, Escherichia coli, group A Streptococcus, and Pre vote/fa species. Crepitus is more common if anaerobic organisms, such as Clostridium perfringens or 8 tragi/is, are involved.

ELISA
ELISA Magdy 5,801 Views • 2 years ago

The purpose of an ELISA is to determine if a particular protein is present in a sample and if so, how much. There are two main variations on this method: you can determine how much antibody is in a sample, or you can determine how much protein is bound by an antibody. The distinction is whether you are trying to quantify an antibody or some other protein. In this example, we will use an ELISA to determine how much of a particular antibody is present in an individuals blood.

ELISAs are performed in 96-well plates which permits high throughput results. The bottom of each well is coated with a protein to which will bind the antibody you want to measure. Whole blood is allowed to clot and the cells are centrifuged out to obtain the clear serum with antibodies (called primary antibodies). The serum is incubated in a well, and each well contains a different serum (see figure below). A positive control serum and a negative control serum would be included among the 96 samples being tested.
