SARS-CoV-2 disease too comes about in a really solid reaction by the safe framework. This safe reaction may directly cause neurological disarranges within the shape of Guillain–Barré disorder. But brain irritation might too by implication cause neurological harm, such as through brain swelling. And it’s related with – in spite of the fact that doesn’t fundamentally cause – neurodegenerative illnesses such as Alzheimer’s and Parkinson’s.

Pancreatic cancer emerges when cells within the pancreas, a glandular organ behind the stomach, start to increase out of control and frame a mass.These cancerous cells have the capacity to attack other parts of the body. There are a number of types of pancreatic cancer. The foremost common, pancreatic adenocarcinoma, accounts for around 90% of cases, and the term "pancreatic cancer" .

The parotid gland Anatomy

2020-01-11T20:12:00.001+02:00

Anatomical Position

The parotid gland is a bilateral structure, which displays a lobular and irregular morphology. Anatomically, it can be divided into deep and superficial lobes, which are separated by the facial nerve.

It lies within a deep hollow, known as the parotid region. The parotid region is bounded as follows:

Superiorly – Zygomatic arch.
Inferiorly – Inferior border of the mandible.
Anteriorly – Masseter muscle.
Posteriorly – External ear and sternocleidomastoid.

The secretions of the parotid gland are transported to the oral cavity by the Stensen duct. It arises from the anterior surface of the gland, traversing the masseter muscle. The duct then pierces the buccinator, moving medially. It opens out into the oral cavity near the second upper molar.

Anatomical Relationships

The anatomical relationships of the parotid gland are of great clinical importance – particularly during parotid gland surgery.

Several important neurovascular structures pass through the gland:

The facial nerve (cranial nerve VII), gives rise to five terminal branches within the parotid gland. These branches innervate the muscles of facial expression.

The external carotid artery (ECA) ascends through the parotid gland. Within the gland, the ECA gives rise to the posterior auricular artery. The ECA then divides into its two terminal branches – the maxillary artery and superficial temporal artery.

The retromandibular vein is formed within the parotid gland by the convergence of the superficial temporal and maxillary veins. It is one of the major structures responsible for venous drainage of the face.

Digital nerve block video demonsetration

2013-03-15T20:10:00.003+02:00

Digital nerve blocks involve infiltrating local anesthesia around the two nerves that supply a digit. Historically this has been done with a local anesthetic without epinephrine however the use of a solution with epinephrine appears to be safe.

Regional nerve blockade, or more commonly nerve block, is a general term used to refer to the injection of local anesthetic onto or near nerves for temporary control of pain. It can also be used as a diagnostic tool to identify specific nerves as pain generators. Permanent nerve block can be produced by destruction of nerve tissue.

Squalamine for Macular Degeneration - 3D Medical Animation

2013-02-22T23:02:00.001+02:00

Neovascular or exudative AMD, the "wet" form of advanced AMD, causes vision loss due to abnormal blood vessel growth (choroidal neovascularization) in the choriocapillaris, through Bruch's membrane, ultimately leading to blood and protein leakage below the macula. Bleeding, leaking, and scarring from these blood vessels eventually cause irreversible damage to the photoreceptors and rapid vision loss if left untreated.Only about 10% of patients suffering from macular degeneration have the wet type.Macular degeneration is not painful, which may allow it to go unnoticed for some time.

Acne Vulgaris laser treatment & diagnosis

2013-02-19T16:33:00.003+02:00

Laser treatment :

Laser surgery has been in use for some time to reduce the scars left behind by acne, but research has been done on lasers for prevention of acne formation itself. The laser is used to produce one of the following effects: to burn away the follicle sac from which the hair grows to burn away the sebaceous gland, which produces the oil to induce formation of oxygen in the bacteria, killing them Since lasers and intense pulsed light sources cause thermal damage to the skin, there are concerns that laser or intense pulsed light treatments for acne will induce hyperpigmented macules (spots) or cause long-term dryness of the skin. The FDA has approved the use of a cosmetic laser for the treatment of acne. However, efficacy studies have used very small sample sizes for periods of six months or less, and have shown contradictory results. Also, laser treatment being relatively new, protocols remain subject to experimentation and revision, and treatment can be quite expensive. Also, some Smoothbeam laser devices had to be recalled due to coolant failure, which resulted in painful burn injuries to patients.

Atherosclerosis powerpoint presentation collection

2013-02-15T20:48:00.000+02:00

Atherosclerosis is a chronic disease that remains asymptomatic for decades. Atherosclerotic lesions, or atherosclerotic plaques are separated into two broad categories: Stable and unstable (also called vulnerable).The pathobiology of atherosclerotic lesions is very complicated but generally, stable atherosclerotic plaques, which tend to be asymptomatic, are rich in extracellular matrix and smooth muscle cells, while, unstable plaques are rich in macrophages and foam cells and the extracellular matrix separating the lesion from the arterial lumen (also known as the fibrous cap) is usually weak and prone to rupture.

Psychiatry is the medical specialty devoted to the study, diagnosis, treatment, and prevention of mental disorders. These include various affective, behavioural, cognitive and perceptual abnormalities. The term was first coined by the German physician Johann Christian Reil in 1808, and literally means the 'medical treatment of the soul' (psych-: soul; from Ancient Greek psykhē: soul; -iatry: medical treatment; from Gk. iātrikos: medical, iāsthai: to heal). A medical doctor specializing in psychiatry is a psychiatrist.

The Life Cycle of the Hepatitis C Virus

2013-02-13T12:30:00.000+02:00

Hepatitis C virus (HCV) infection afflicts more than 170 million people worldwide, with the great majority of patients with acute hepatitis C developing chronic HCV infection. It can ultimately result in liver cirrhosis, hepatic failure or hepatocellular carcinoma, which are responsible for hundreds of thousands of deaths each year. Despite the discovery of HCV over 15 years ago, our knowledge of the HCV lifecycle has been limited by our inability to grow the virus in cell culture, as well as by the lack of small-animal models of HCV infection. Nevertheless, data accumulated through the use of multiple in vitro and in vivo study systems have provided a general picture of the biology of HCV, although sometimes with contradictory results. Herein, we summarize our current understanding of the HCV genome and how its structure and encoded gene products, in a complex interplay with host cell factors, might orchestrate a productive viral lifecycle while evading the scrutiny of the host immune system. The recently developed robust in vitro HCV infection systems should help fill in some of the gaps in understanding the HCV lifecycle in the next few years.

What is Blood Cancer ?

2013-02-12T20:04:00.002+02:00

For the analysis of a suspected hematological malignancy, a complete blood count and blood film are essential, as malignant cells can show in characteristic ways on light microscopy. When there is lymphadenopathy, a biopsy from a lymph node is generally undertaken surgically. In general, a bone marrow biopsy is part of the "work up" for the analysis of these diseases. All specimens are examined microscopically to determine the nature of the malignancy. A number of these diseases can now be classified by cytogenetics (AML, CML) or immunophenotyping (lymphoma, myeloma, CLL) of the malignant cells.

Breast Cancer 3D Animation

2013-02-07T18:51:00.002+02:00

Breast cancer is a type of cancer originating from breast tissue, most commonly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Cancers originating from ducts are known as ductal carcinomas, while those originating from lobules are known as lobular carcinomas. Breast cancer occurs in humans and other mammals. While the overwhelming majority of human cases occur in women, male breast cancer can also occur.The benefit versus harms of breast cancer screening is controversial. The characteristics of the cancer determine the treatment which may include surgery, medicationss (hormonal therapy and chemotherapy), radiation and/or immunotherapy. Surgical provides the single largest benefit, and to increase the likelihood of cure, several chemotherapy regimens are commonly given in addition. Radiation is used after breast-conserving surgery and substantially improves local relapse rates and in many circumstances also overall survival.Worldwide, breast cancer accounts for 22.9% of all cancers (excluding non-melanoma skin cancers) in women. In 2008, breast cancer caused 458,503 deaths worldwide (13.7% of cancer deaths in women). Breast cancer is more than 100 times more common in women than in men, although men tend to have poorer outcomes due to delays in diagnosis.Prognosis and survival rates for breast cancer vary greatly depending on the cancer type, stage, treatment, and geographical location of the patient. Survival rates in the Western world are high; for example, more than 8 out of 10 women (84%) in England diagnosed with breast cancer survive for at least 5 years. In developing countries, however, survival rates are much poorer.

Stroke 3D Animation

Risk factors

The most important modifiable risk factors for stroke are high blood pressure and atrial fibrillation (although magnitude of this effect is small: the evidence from the Medical Research Council trials is that 833 patients have to be treated for 1 year to prevent one stroke. Other modifiable risk factors include high blood cholesterol levels, diabetes, cigarette smoking (active and passive), heavy alcohol consumption and drug use, lack of physical activity, obesity, processed red meat consumption and unhealthy diet. Alcohol use could predispose to ischemic stroke, and intracerebral and subarachnoid hemorrhage via multiple mechanisms (for example via hypertension, atrial fibrillation, rebound thrombocytosis and platelet aggregation and clotting disturbances).The drugs most commonly associated with stroke are cocaine, amphetamines causing hemorrhagic stroke, but also over-the-counter cough and cold drugs containing sympathomimetics.No high quality studies have shown the effectiveness of interventions aimed at weight reduction, promotion of regular exercise, reducing alcohol consumption or smoking cessation. Nonetheless, given the large body of circumstantial evidence, best medical management for stroke includes advice on diet, exercise, smoking and alcohol use. Medication or drug therapy is the most common method of stroke prevention; carotid endarterectomy can be a useful surgical method of preventing stroke.
