Coronavirus

Hello friends may u already have heard about this new Virus, but here is what all u need to know about it - What is Coronavirus? According to the World Health Organization, coronaviruses are a family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS) and severe acute respiratory syndrome (SARS). These viruses are transmitted between animals and people. A novel coronavirus, identified by Chinese authorities on January 7 and currently named 2019-nCoV, is a new strain that had not been previously identified in humans. Little is known about it, although human-to-human transmission has been confirmed. Symptoms - According to the WHO, signs of infection include respiratory symptoms, fever, cough, shortness of breath and breathing difficulties. In more severe cases, it can lead to pneumonia, severe acute respiratory syndrome, kidney failure and even death. Reports say the incubation period of the coronavirus remains unknown, but other sources say it could be between 10 to 14 days. Prevention - There is currently no vaccine to prevent 2019-nCoV infection. The best way to prevent infection is to avoid being exposed to this virus. Wash your hands often with soap and water for at least 20 seconds. If soap and water are not available, use an alcohol-based hand sanitizer. Avoid touching your eyes, nose, and mouth with unwashed hands. Avoid close contact with people who are sick. Stay home when you are sick. Cover your cough or sneeze with a tissue, then throw the tissue in the trash. Clean and disinfect frequently touched objects and surfaces.

Quincke's Pulse

A 34-year-old man presented with a 6-to-8-week history of fatigue, malaise, fevers, and night sweats. He had a history of a congenital quadricuspid aortic valve and 16 years earlier had undergone a Ross procedure (during which the aortic valve was replaced by a pulmonary autograft and the pulmonary valve was replaced by a pulmonary homograft). On examination, the temperature was 39.2°C and the blood pressure 130/50 mm Hg. A grade 3/4 diastolic murmur was heard over the base of the heart. Alternating flushing and blanching of the nail beds of several fingers in concert with the cardiac cycle, known as Quincke's pulse, was easily visualized (see video). Transthoracic echocardiography confirmed severe insufficiency of the pulmonary autograft and homograft in association with vegetations. Blood cultures grew Streptococcus milleri. The patient underwent replacement of both grafts. Quincke's pulse is a physical finding of severe and chronic aortic insufficiency. Regurgitant blood flow into a dilated left ventricle during diastole leads to a decrease in diastolic pressure and a consequent increase in stroke volume, resulting in blanching and flushing, respectively, of the nail bed.

Reversible Cerebral Vasoconstriction after Preeclampsia

Reversible Cerebral Vasoconstriction after Preeclampsia

A 41-year-old woman underwent cesarean section for preeclampsia at 30 weeks of gestation. Two days after delivery, total visual loss occurred suddenly, followed by weakness of the left leg. Magnetic resonance imaging of the brain showed areas of restricted diffusion in both occipital cortexes, a finding that was consistent with acute infarction (Panel A). Magnetic resonance angiography (MRA) revealed generalized vasoconstriction of the anterior and posterior cerebral circulation (Panel B, arrows). The patient started to regain her vision after 12 hours, with almost complete recovery over the following days. Repeat MRA 4 weeks after the event revealed normalized vessel caliber, in keeping with reversible cerebral vasoconstriction (Panel C). Cerebral venous sinus thrombosis, the posterior reversible encephalopathy syndrome, and primary angiitis of the central nervous system should be considered initially in the differential diagnosis of reversible cerebral vasoconstriction.

Simultaneous Gangrene of Both Left Extremities

Simultaneous Gangrene of Both Left Extremities

A 47-year-old woman with a long history of diabetes mellitus, hypertension, and moderate obesity — with a body-mass index (the weight in kilograms divided by the square of the height in meters) of 34 — presented with a 1-week history of pain, paresthesia, pallor of the left arm and leg, and dry gangrene (Panels A and B). Neither a history nor a physical examination revealed evidence of a vasculitic, hypercoagulable, or embolic disorder. An ultrasound evaluation showed a thrombus of the distal two thirds of the left brachial artery and its bifurcation as well as a thrombus of the left external iliac and common femoral arteries. No definite source of the emboli was found, but an embolus from the heart released during a transient arrhythmia was suspected (she had no known history of atrial fibrillation, and her echocardiogram was normal). Balloon brachial and femoral thrombectomies and primary amputations were performed. During surgery, clots were found. The patient died a few days after surgery from the sepsis associated with the gangrene.

First 3D Printed Vascularized Heart - MEDizzy Journal

Yes, you read it right; for the first time ever, on 15th of April 2019, Israeli researchers of Tel Aviv University have printed a 3D heart, engineered entirely by human tissues. Up until this date, technological advancements had only led scientists to printing of simple tissues, with no blood vessels, making this newly engineered vascularized …

A Meningioma is a Tumor that arises from the meninges — the membranes that surround your brain and spinal cord. Most Meningiomas are noncancerous (benign), though rarely a Meningioma may be Cancerous (malignant). Some Meningiomas are classified as atypical, meaning they're neither benign nor malignant but, rather, something in between. A Meningioma doesn't always require immediate treatment. A Meningioma that causes no significant signs and symptoms may be monitored over time. Signs and symptoms of a Meningioma typically begin gradually and may be very subtle at first. Depending on where in the brain or, rarely, spine the Tumor is situated, signs and symptoms may include: Changes in vision, such as seeing double or blurriness Headaches that worsen with time Hearing loss Memory loss Loss of smell Seizures Weakness in your arms or legs

Motor cortex arteriovenous malformation

Department of Neurosurgery, Barrow Neurological Institute, St. Joseph’s Hospital and Medical Center, Phoenix, Arizona Supratentorial arteriovenous malformations in eloquent territories can be difficult to resect. This video presents the treatment of a patient with a symptomatic 3-cm arteriovenous malformation in the left motor strip. At the authors’ institution, per the surgeon’s discretion, preoperative angiography is performed to evaluate the need for preoperative embolization. Multimodality treatment reduced the microsurgical risk by allowing early occlusion of a draining vein, by decreasing overall intraoperative hemorrhage, and by allowing minimal pial dissection in the deep aspect of the arteriovenous malformation that abutted the corticospinal tract. The choice of embolysate was an additional nuance of the embolization. Alfred P. See, MD, Bruno C. Flores, MD, Karam Moon, MD, Andrew F. Ducruet, MD, Robert F. Spetzler, MD, and Felipe C. Albuquerque, MD

Nav-guided transsylvian approach & microsurgical resection of a deep left temporal low-grade AVM

This video demonstrates stereotactic-guided resection of a ruptured diffuse left temporal arteriovenous malformation (AVM) in an adolescent male who presented with headache and speech difficulties. The diffuse nidus of the AVM, 25 mm in size, was located in the posterior superior temporal gyrus, with drainage into the sylvian veins (Spetzler-Martin Grade II). The AVM was located stereotactically, and resection was performed through a small corticectomy. The clot cavity was evacuated. Feeding branches to the AVM were identified during careful dissection, and parent M1 and M2 branches were preserved. The patient recovered well, with no residual speech deficit. Postoperative angiogram demonstrated complete AVM removal. William T. Couldwell, MD, PhD Department of Neurosurgery, Clinical Neurosciences Center, University of Utah, Salt Lake City, Utah
