Diagnosis and the functions of Parkinsonism clinics

It is easy to recognize the disease when it is flowery. Typical deadpan face, stooping posture, generalized rigidity and shaking of hands are diagnostic. Secondary functions like excessive salivation (due to excess cholinergic), the infrequency of normal eye blinking, micrographia (written becoming small and distorted letters), Seborrhea and appearance of the primitive reflexes are diagnostic. Glabellar tap is a primitive reflex diagnostics that can be easily aroused. The nose is exploited gently and this evokes the eyes flashing. Tapping in the normal individual leads to the Elimination of this response, considering that in Parkinsonism this response can be raised repeatedly.

Differential diagnosis: Parkinsonism Postencephalitic is recognized by the history of encephalitis in the past and the presence of ocular manifestations as oculogyric crisis. This is sudden jerking movements conjugated eyes, occurring generally upward, less frequently in other directions as well. Parkinsonism may occur as part of other neurological diseases. It can coexist with atherosclerosis - used to be known as arteriosclerotic parkinsonism. There was no consensus of opinion if Parkinsonism is caused by atherosclerosis.

Clinical features
Four Cardinals of Parkinsonism characteristics hypokinesia, tremors, rigidity, postural riots.
1 Hypokinesia or bradykinesia: these terms relate to poverty automatic movements and Detective voluntary due to motor planning. Voluntary movements are slow to start, reduced, and lack of precision. Movements associated in footer (for example, balancing arms, etc.) has been reduced considerably. While voluntary activity is difficult and time-consuming, reflex activity remains normal for considerable periods. Although voluntary movements are slow, power is usually normal.

2 Rigidity: Increase in tone, which manifests itself as the rigidity of the limbs and the trunk is characteristic of parkinsonism. This rigidity is present in the range of motion (lead pipe stiffness), unlike spasticity injury of upper motor neuron where increased tone feels the most at the beginning of the movement. When increased tone associated with tremor, results in cogwheel rigidity type. The facial muscles stiffness gives rise to a mask with no expression-like facies.

3 Tremor: The characteristic tremor occurs at rest. Initially, sees the trembling hands, but later that this extends to the lower extremities. The thumb moves transversely across the fingertips bending rhythmically and this is appropriate describe it as the pill the rolling motion. Later, tremor becomes the largest and also in the limbs, face, lips and also tremulous language.

4. The alteration of the position: patient assumes a generalised flexion attitude makes lower us forward. Walks with short steps and walk, he gains speed, and tends to give forward. This phenomenon is called festination. Terms and retropulsion propulsion are used to denote the phenomenon seen when the patient standing is gently pushed forward or backward. The patient is moved forwards or backwards without control. Due to stiffness in movement, the patient it is difficult to turn around when walking. He tends to fall with more frequency and postural adjustments become difficult. Deep reflexes are usually affected. Normally higher faculties, as intelligence and memory are preserved. Speech becomes slow and boring. There is lack of initiative and the patient tends to restrict its activity gradually.

The normal response body to the depletion of dopamine is increasing the number of dopamine receptors. Parkinsonism symptoms only appear when it fails this compensatory mechanism. Available medications nowadays do not treat the cause of the disease. They can even reduce dopamine receptors when used in a long term basis. They can therefore fail drugs alleviate the symptoms in advanced cases. In terms of functional inability, Parkinsonism remains a disease with a poor prognosis.

Abdominal Aortic Aneurysm - Online Medical Diagnosis

Abdominal aortic aneurysm is described as a weak area in the muscular wall of the abdominal aorta, which causes a balloons of the blood vessel. This ballooned area becomes more prone to rupture grows. This condition can be life threatening and is considered a medical emergency.

In this article shall be share with you the symptoms, causes and treatments for aortic aneurysm abdominal., will then show you how the condition is diagnosed.

Abdominal aortic aneurysm

Symptoms - this condition can cause low back pain. This pain could be described as a deep or dull pain.In some cases, abdominal pain may be felt but this disorder often asymptomatic physics to all and is discovered by accident during a routine review of Physics in the doctor's Office.

Causes - an aneurysm is often seen in men who are more than 50 years.Men at high risk have a history of hardened arteries or poor circulation in limbs, i.e. frequent feet frio.Otros risk factors include poor health habits and smoking in general.

Diagnosis - during a routine by a health professional examination an abnormal pulse in the abdomen can be detected.Other possible ways to diagnose this condition include x-ray routine lumbar spine that reveals calcium deposits in the wall of the aneurysm.It can also cause significant erosion of the inferior vertebra.

Treatment - condition typically requires a surgery to reduce the aneurisma.Si delayed treatment or condition goes undetected can become a medical emergency and immediate steps must take to prevent rupture.

An abdominal aortic aneurysm is a serious condition described best as a weakened part of the large blood vessel that descends from abdomen.Los symptoms not are always experienced by the person with aneurysm and this can allow you to grow more dangerous as important crece.Es to learn more about this condition.

Diagnosis, management of coma and Brain death

In neurological disorders, the location of signs pointing to parts of the nervous system disease can be for example present, hemiplegia, palsies of cranial nerves, focal seizures, etc. Meningitis and subarachnoid haemorrhage associated with signs of meningeal irritation such as neck stiffness, Kernig sign and Brudzinski signs. In metabolic coma, location of signs may be absent. In poisoning, other effects of the poison can also be evident.

Research

1. Investigations of routine to exclude systemic disorders include a thorough analysis of urine, estimation of arterial blood gases, electrolytes, pH, blood sugar urea.

2. In the alleged poisoning, gastric chemical examination for poison materials shall be submitted.

3. The cerebrospinal fluid should be considered suspected meningitis, encephalitis, hemorrage subarachnoid or meningeal leukemia.

4 Evidence decided by clinical examination and the progress of the EEG, neurorradiologia, CT case analysis, NMR imaging and radioisotope scanning may indicate in many cases.

Management

Directorate-General: Comatose patients are very sensitive to develop several complications as a result of the loss of reflexes protectors and these must be avoided. Maintenance of the respiratory tract is paramount.The neck has to maintain extended to avoid "fall-back of the tongue. If necessary, you must enter a patient airway. Secretions must eliminate postural drainage and aspiration in cases with depression respiratory artificial ventilation must be established early.In some cases, may be necessary to tracheostomy.

Maintenance of nutrition and fluid and electrolyte balance: adequate nutrition (at least 2000 cals per day and 2 L of fluid) in the form of milk, sugar, eggs, cereals, salt and water are given on a probe nasogastric. food by mouth carries the risk of aspiration in airway and, therefore, should be avoided.Parenteral nutrition starts through intravenous route to complement the nasogastric tube feeding. Intravenous needle must maintain prolonged aseptico.Enfermedad, the position of the needle must be changed every 36 to 48 hours to avoid thrombophlebitis.

Skin care: patients develop sores due to continuous pressure on localized areas. This risk is to avoid activating the patient in bed every two to four hours and keep skin clean and dry.An adequate intake of protein helps to minimize the risk of ulcers of the cama.Cuando coma is likely to extend, special beds which are capable of converting to patients, and help to avoid pressure on localized areas can be used with advantage.

Bladder and bowel: the patient unconscious voids your bladder and bowel automatically and this causes many problems in nursing.Institution of a closed for bladder drainage system helps to avoid this clothing dirt and prevent infection.Bowels moved by small enemas or suppositories at regular intervals.

Positioning of limbs and physiotherapy: members should be kept positions best to avoid fixed deformities.Regular passive movements to limbs help in the prevention of venous thrombosis and pulmonary embolism later.

Specific therapy: this depends on the cause of the comma.Anticonvulsant medication indicated if seizures occur.Intercurrent infection (urinary or cutaneous has to be treated with antibiotics, breathing).

Brain death

This issue has gained importance from the removal of organs for transplantation is performed from patients who have no chance of recuperarse.Los patients undergoing support including artificial ventilation measures can happen in a stage where brain functions and the brain stem is irretrievably lost, the patient can continue have circulation of these housings apoyo.Retirada measures will lead to the death fisica.La decision to withdraw these housings is doctor-legales.Por therefore, brain death must have been diagnosed with the help of deep without any movement reflexes for more than 12 hours, EEG.Coma lack of brain stem (Oculocephalic reflexes, reflection of light and spontaneous breathing) reflexes and a flat EEG record indicates irreversible death cerebral.estos brain damage criteria are not valid if the comma is the result of hypothermia poisons overdose.
