(From Merck Index, 11th ed)Sclerosing Solutions: Chemical agents injected into blood vessels and lymphatic sinuses to shrink or cause localized THROMBOSIS; FIBROSIS, and obliteration of the vessels. This treatment is applied in a number of conditions such as VARICOSE VEINS; HEMORRHOIDS; GASTRIC VARICES; ESOPHAGEAL VARICES; PEPTIC ULCER HEMORRHAGE.Pericardial Effusion: Fluid accumulation within the PERICARDIUM. Serous effusions are associated with pericardial diseases. Hemopericardium is associated with trauma. Lipid-containing effusion (chylopericardium) results from leakage of THORACIC DUCT. Severe cases can lead to CARDIAC TAMPONADE.Chest Tubes: Plastic tubes used for drainage of air or fluid from the pleural space. Their surgical insertion is called tube thoracostomy.Cerebrospinal Fluid Shunts: Tubes inserted to create communication between a cerebral ventricle and the internal jugular vein. Their emplacement permits draining of cerebrospinal fluid for relief of hydrocephalus or other condition leading to fluid accumulation in the ventricles.Cerebrospinal Fluid Proteins: Proteins in the cerebrospinal fluid, normally albumin and globulin present in the ratio of 8 to 1. Increases in protein levels are of diagnostic value in neurological diseases. (Brain and Bannister's Clinical Neurology, 7th ed, p221)Hydrocephalus: Excessive accumulation of cerebrospinal fluid within the cranium which may be associated with dilation of cerebral ventricles, INTRACRANIAL HYPERTENSION; HEADACHE; lethargy; URINARY INCONTINENCE; and ATAXIA.Ventriculoperitoneal Shunt: Surgical creation of a communication between a cerebral ventricle and the peritoneum by means of a plastic tube to permit drainage of cerebrospinal fluid for relief of hydrocephalus. (From Dorland, 28th ed)Adsorption: The adhesion of gases, liquids, or dissolved solids onto a surface. It includes adsorptive phenomena of bacteria and viruses onto surfaces as well. ABSORPTION into the substance may follow but not necessarily.Cerebrospinal Fluid: A watery fluid that is continuously produced in the CHOROID PLEXUS and circulates around the surface of the BRAIN; SPINAL CORD; and in the CEREBRAL VENTRICLES.Particulate Matter: Particles of any solid substance, generally under 30 microns in size, often noted as PM30. There is special concern with PM1 which can get down to PULMONARY ALVEOLI and induce MACROPHAGE ACTIVATION and PHAGOCYTOSIS leading to FOREIGN BODY REACTION and LUNG DISEASES.Neurosurgery: A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system.Neurology: A medical specialty concerned with the study of the structures, functions, and diseases of the nervous system.Choroid Plexus: A villous structure of tangled masses of BLOOD VESSELS contained within the third, lateral, and fourth ventricles of the BRAIN. It regulates part of the production and composition of CEREBROSPINAL FLUID.Community Medicine: A branch of medicine concerned with the total health of the individual within the home environment and in the community, and with the application of comprehensive care to the prevention and treatment of illness in the entire community.Cross Infection: Any infection which a patient contracts in a health-care institution.Biological Science Disciplines: All of the divisions of the natural sciences dealing with the various aspects of the phenomena of life and vital processes.

In this syndrome, atrial impulses are abnormally conducted to the HEART VENTRICLES via an ACCESSORY CONDUCTING PATHWAY that is located between the wall of the right or left atria and the ventricles, also known as a BUNDLE OF KENT. The inherited form can be caused by mutation of PRKAG2 gene encoding a gamma-2 regulatory subunit of AMP-activated protein kinase.Catheter Ablation: Removal of tissue with electrical current delivered via electrodes positioned at the distal end of a catheter. Energy sources are commonly direct current (DC-shock) or alternating current at radiofrequencies (usually 750 kHz). The technique is used most often to ablate the AV junction and/or accessory pathways in order to interrupt AV conduction and produce AV block in the treatment of various tachyarrhythmias.Pre-Excitation Syndromes: A group of conditions in which HEART VENTRICLE activation by the atrial impulse is faster than the normal impulse conduction from the SINOATRIAL NODE. In these pre-excitation syndromes, atrial impulses often bypass the ATRIOVENTRICULAR NODE delay and travel via ACCESSORY CONDUCTING PATHWAYS connecting the atrium directly to the BUNDLE OF HIS.Electrocardiography: Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY.Tachycardia: Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.Tachycardia, Ectopic Atrial: Abnormally rapid heartbeats originating from one or more automatic foci (nonsinus pacemakers) in the HEART ATRIUM but away from the SINOATRIAL NODE. Unlike the reentry mechanism, automatic tachycardia speeds up and slows down gradually. The episode is characterized by a HEART RATE between 135 to less than 200 beats per minute and lasting 30 seconds or longer.Tachycardia, Supraventricular: A generic expression for any tachycardia that originates above the BUNDLE OF HIS.Ventricular Flutter: A potentially lethal cardiac arrhythmia characterized by an extremely rapid, hemodynamically unstable ventricular tachycardia (150-300 beats/min) with a large oscillating sine-wave appearance. If untreated, ventricular flutter typically progresses to VENTRICULAR FIBRILLATION.Heart Conduction System: An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.Tachycardia, Paroxysmal: Abnormally rapid heartbeats with sudden onset and cessation.Dictionaries, MedicalDictionaries as Topic: Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.Dictionaries, ChemicalTerminology as Topic: The terms, expressions, designations, or symbols used in a particular science, discipline, or specialized subject area.

A statewide survey was designed to develop a better understanding of the current practices and problems encountered with medication administration through enteral feeding catheters (EFCs). The sample of 223 registered nurses and licensed practical nurses estimated that a median of 1096 of patients received medications through an EFC. EFC obstruction was estimated to have occured a median of 1.5 times per week, with 50% of obstructions estimated to be due to medication administration. Nine of 14 spic medications reported as most frequently contributing tofeeding catheter obstruction available in liquid form, yet tablets were crushed and given When nurses perceived the pharmacy department as helping them insure that liquid dosage form was used, there was greater use of liquid forms, less use of crushed forms, and less medication-associated catheter obstruction. In this sample, the majority of nurses did not follow consistently the few recommendations available.

My senior supervisor Dr. Tomono Takahashi, whose speciality is Diabetology, also taught me about the examination and treatment of DM (diabetes mellitus). Not only did she teach me, but she organised visits for me in both Scintigraphy (of suprarenal gland) and an operation with the famous DaVinci robot in Urology (prostatectomy). It was fascinating to see them both. I also listened to a lecture about a nasal spray for allergic rhinitis in medical environment. My favourite procedure however was the adrenal vein sampling,in which I took part twice. I helped in putting the blood samples in the correct containers. I also learned how to insert a PICC (peripherally inserted central venous catheter) with ultrasound, which added a great skill to my medical carreer. Apart from professional work we went to eat out with the doctors of our team to a sushi restaurant, and we visited an owl cafe with two of the doctors, it was highly entertaining.

Abstract:. OBJECTIVE: To compare the efficacy of two concentrations of heparin to clear the lumen of in vitro clotted neonatal, peripherally inserted central catheters (PICCs).. METHODS: This is an in vitro, experimental quantitative study of 76 neonatal 2.0 Fr PICCs coagulated in vitro. The catheters were divided into two groups of 38 PICCs each. In both groups an infusion of low molecular weight heparin was administered with a dose of 25IU/mL for Group 1 and 50IU/mL for Group 2. The negative pressure technique was applied to the catheters of both groups at 5, 15 and 30minutes and at 4hours to test their permeability. Kaplan-Meier survival analysis was used to verify the outcome of the groups according to time intervals.. RESULTS: The comparison between both groups in the first five minutes showed that more catheters from Group 2 were cleared compared to Group 1 (57.9 vs. 21.1%, respectively). Kaplan-Meier survival analysis showed that less time was needed to clear catheters treated with ...
Abstract:. BACKGROUND: Peripherally inserted central venous catheters (PICCs) are widely used in patients with cancer. Catheter usage is one of the risk factors for venous thromboembolism. We aimed to scrutinize the incidence and risk factors for PICC-related upper extremity venous thrombosis (UEVT) in patients with lung cancer receiving chemotherapy.. PATIENTS AND METHODS: We performed a retrospective cohort study of patients with lung cancer with PICC insertion undergoing chemotherapy. Symptomatic PICC-UEVT was diagnosed by ultrasound. The relationship between chemotherapeutic agent exposure and PICC-UEVT was evaluated. Patient-, catheter-, and insertion-related factors were analyzed in univariable and multivariable logistic regression to identify significant independent risk factors for PICC-UEVT in patients with lung cancer.. RESULTS: A total of 328 patients with lung cancer having PICC undergoing chemotherapy were included, for a total of 34 895 catheter days. Seventeen (5.2%) patients ...

Cool the swelling. Put a cold compress on the outside of your cheek if youve got swelling from the toothache.. Chill the pain. Holding an ice cube or cold water in the. mouth may relieve the pain. But if you find that it simply aggravates your sensitive tooth, skip it.. Keep your head up. Elevating your head can decrease the pressure in the area and may lessen throbbing pain.. Rinse. You cant really rinse away the pain (although its a pleasant thought), but you can rinse with warm water to remove any food debris that may be causing or aggravating the pain. A piece of food that gets stuck in the gum can hurt as much as damaged tooth pulp. Stir one teaspoon salt in a glass of warm water, swish it around in your mouth, then spit it out.. Floss. No, its not a cure, but flossing is another way to remove any food debris that could be trapped. The rubber tip on your toothbrush or a toothpick (if used with caution) can help dislodge stuck food, too.. Be careful with the hot, the cold, and the sweet. ...

Regular dental cleanings remove the tarter, plaque, and stains that naturally collect on and in-between teeth. Even with regular brushing and flossing, these substances can build up, cause decay and gum disease, and discolor your teeth. Bi-annual cleanings by a dental hygienist can also improve your overall health. During cleanings, dentists screen for oral cancers, gum disease, tooth decay, and bite problems. Regular cleanings may even help prevent stroke and heart disease.. The Dentists and Hygienists of Premier Dental Group use a variety of tools to clean your teeth. X-rays help identify problem areas and decay present on the teeth. Dental mirrors help them see into hard-to-reach areas of your mouth to ensure a complete examination and cleaning. Ultrasonic tools are used to help loosen tartar. Curettes, or scalers, are used to remove finer deposits on the teeth. Finally, low-speed polishers with curved rubber tips are used with a grainy, toothpaste-like solution to smooth and shine the teeth. ...

Central venous catheters (CVC) are vital for patients receiving chemotherapy not compatible with peripheral infusion. Thousands of centrally and peripherally inserted central venous catheters are inserted into patients with cancer each year. All types of intravascular catheters are associated with complications. These complications may be divided into infectious, thrombotic, mechanical and occlusive events. All of these events have the potential to harm patients and cause additional expense for the health-care system. Furthermore, the above-mentioned complications are largely avoidable through proper patient selection, insertion technique, hygiene precautions and catheter maintenance.. Catheter-related infections and deep venous thrombosis are the two most common and feared CVC related complications. Infection in a catheter can cause lifethreatening bacteraemia, and thrombosis can lead to pulmonary embolisation, post-thrombotic syndrome and stenosis of the vessel affected. Many studies ...
Normal-pressure hydrocephalus (NPH) was the first treatable type of dementia everdescribed. Hakim and Adams described the entity they called normal pressurehydrocephalus in 1965 (Hakim & Adams, 1965). Cerebrospinal fluid shunting forhydrocephalus was the first wide treatment available for the disease. In the followingyears, an initially uncritical enthusiasm for cerebrospinal fluid (CSF) shunting wasgradually dampened because of the underdeveloped shunt technology, low clinicalsuccess rates, and frequent complications (Dippel & Habbema, 1993).The most frequent complication is ventricular catheter obstruction, which may accountfor 50 to 80% of newly inserted shunts (Bergsneider et al., 2006). Although many factorscontribute to this (Harris & McAllister, 2012), the main one is related to flowcharacteristics of the catheter within the hydrocephalic brain (Harris & McAllister, 2012;Lin, Morris, Olivero, Boop & Sanford, 2003).
