Roseola
Roseola, also known as sixth disease, is an infectious disease caused by certain types of human herpes viruses. Most infections occur before the age of three. Symptoms vary from absent to the classic presentation of a fever of rapid onset followed by a rash. The fever generally lasts for three to five days, while the rash is generally pink and lasts for less than three days. Complications may include febrile seizures, with serious complications being rare. It is caused by '' human herpesvirus 6'' (HHV-6A, HHV-6B) or ''human herpesvirus 7'' (HHV-7). Spread is usually through the saliva of those who are otherwise healthy. However, it may also spread from the mother to baby during pregnancy. Diagnosis is typically based on symptoms and does not need to be confirmed with blood tests (PCR or antigen). Low numbers of white blood cells may also be present. Treatment includes sufficient fluids and medications to treat the fever. Nearly all people are infected at some point in time. M ...

Fifth Disease
Erythema infectiosum, fifth disease, or slapped cheek syndrome is one of several possible manifestations of infection by parvovirus B19. Fifth disease typically presents as a rash and is more common in children. While parvovirus B19 can affect humans of all ages, only two out of ten individuals will present with physical symptoms. The name "fifth disease" comes from its place on the standard list of rash-causing childhood diseases, which also includes measles (first), scarlet fever (second), rubella (third), Dukes' disease (fourth, but is no longer widely accepted as distinct from scarlet fever), and roseola (sixth). Treatment is mostly supportive. Signs and symptoms Fifth disease starts with a low-grade fever, headache, rash, and cold-like symptoms, such as a runny or stuffy nose. These symptoms pass, then a few days later, the rash appears. The bright red rash most commonly appears in the face, particularly the cheeks. This is a defining symptom of the infection in children ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Exanthem
An exanthem is a widespread rash occurring on the outside of the body and usually occurring in children. An exanthem can be caused by toxins, drugs, or microorganisms, or can result from autoimmune disease. The term exanthem is from the Greek el, ἐξάνθημα, translit=exánthēma, lit=a breaking out, label=none. It can be contrasted with enanthems which occur inside the body, such as on mucous membranes. Infectious exanthem In 1905, the Russian-French physician Léon Cheinisse (1871–1924), proposed a numbered classification of the six most common childhood exanthems. Of these six "classical" infectious childhood exanthems, four are viral. Numbers were provided in 1905. The four viral exanthema have much in common, and are often studied together as a class. They are: Scarlet fever, or "second disease", is associated with the bacterium ''Streptococcus pyogenes''. Fourth disease, also known as "Dukes' disease" is a condition whose existence is not widely accepted t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Febrile Seizures
A febrile seizure, also known as a fever fit or febrile convulsion, is a seizure associated with an increased body temperature but without any intracranial infection. Febrile seizures affect 2–7% of children and are more common in boys than girls. They most commonly occur in children between the ages of 6 months and 5 years with a higher incidence around 18 month of age. Most seizures last less than five minutes, and the child typically recovers quickly. There are two types: simple febrile seizures and complex febrile seizures Simple febrile seizures involve an otherwise healthy child with a single, one episode of generalized seizure lasting less than 15 minutes. Complex febrile seizures have one of more of the following: focal symptoms such as jerking of only one side of the body, duration of > 15 minutes, or 2 or more seizures within 24 hours. About 60-70% are classified as simple febrile seizures and 30-40% complex. Febrile seizures are triggered by fever, typically due to ...

Morbilliform
The term morbilliform refers to a rash that looks like measles. The rash consists of macular lesions that are red and usually 2–10 mm in diameter but may be confluent in places. A morbilliform rash is a rose-red flat ( macular) or slightly elevated (maculopapular) eruption, showing circular or elliptical lesions varying in diameter from 1 to 3 mm, with healthy-looking skin intervening. Patients with measles will have the rash but there are other syndromes and infections that will display the same symptom such as patients with Kawasaki disease, meningococcal petechiae or Waterhouse-Friderichsen syndrome, Dengue, Roseola, congenital syphilis,American Family Physician Sept 1st 2012 Vol 86 No 5 pp381-482 Syphilis: A re-emerging infection. rubella, Echovirus 9,thefreedictionary.com > morbilliform rashRetrieved on Nov 30, 2009 drug hypersensitivity reactions (in particular with certain classes of antiretroviral drugs, such as abacavir and nevirapine, and also the antiepi ...

Status Epilepticus
Status epilepticus (SE), or status seizure, is a single seizure lasting more than 5 minutes or 2 or more seizures within a 5-minute period without the person returning to normal between them. Previous definitions used a 30-minute time limit. The seizures can be of the tonic–clonic type, with a regular pattern of contraction and extension of the arms and legs, or of types that do not involve contractions, such as absence seizures or complex partial seizures. Status epilepticus is a life-threatening medical emergency, particularly if treatment is delayed. Status epilepticus may occur in those with a history of epilepsy as well as those with an underlying problem of the brain. These underlying brain problems may include trauma, infections, or strokes, among others. Diagnosis often involves checking the blood sugar, imaging of the head, a number of blood tests, and an electroencephalogram. Psychogenic nonepileptic seizures may present similarly to status epilepticus. Other condit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foscarnet
Foscarnet (phosphonomethanoic acid), known by its brand name Foscavir, is an antiviral medication which is primarily used to treat viral infections involving the Herpesviridae family. It is classified as a pyrophosphate analog DNA polymerase inhibitor. Foscarnet is the conjugate base of a chemical compound with the formula HO2CPO3H2 (Trisodium phosphonoformate). Foscarnet was approved for medical use in 1991. Medical use This phosphonic acid derivative (marketed by Clinigen as foscarnet sodium under the trade name Foscavir) is an antiviral medication used to treat herpes viruses, including drug-resistant cytomegalovirus (CMV) and herpes simplex viruses types 1 and 2 (HSV-1 and HSV-2). It is particularly used to treat CMV retinitis. Foscarnet can be used to treat highly treatment-experienced patients with HIV as part of salvage therapy. Mechanism of action Foscarnet is a structural mimic of the anion pyrophosphate that selectively inhibits the pyrophosphate binding site on v ...

Encephalitis
Encephalitis is inflammation of the brain. The severity can be variable with symptoms including reduction or alteration in consciousness, headache, fever, confusion, a stiff neck, and vomiting. Complications may include seizures, hallucinations, trouble speaking, memory problems, and problems with hearing. Causes of encephalitis include viruses such as herpes simplex virus and rabies virus as well as bacteria, fungi, or parasites. Other causes include autoimmune diseases and certain medications. In many cases the cause remains unknown. Risk factors include a weak immune system. Diagnosis is typically based on symptoms and supported by blood tests, medical imaging, and analysis of cerebrospinal fluid. Certain types are preventable with vaccines. Treatment may include antiviral medications (such as acyclovir), anticonvulsants, and corticosteroids. Treatment generally takes place in hospital. Some people require artificial respiration. Once the immediate problem is under co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infectious Disease (medical Specialty)
Infectious diseases or ID, also known as infectiology, is a medical specialty dealing with the diagnosis and treatment of infections. An infectious diseases specialist's practice consists of managing nosocomial ( healthcare-acquired) infections or community-acquired infections and is historically associated with hygiene, epidemiology, clinical microbiology, travel medicine and tropical medicine. Scope Infectious diseases specialists typically serve as consultants to other physicians in cases of complex infections, and often manage patients with HIV/AIDS and other forms of immunodeficiency. Although many common infections are treated by physicians without formal expertise in infectious diseases, specialists may be consulted for cases where an infection is difficult to diagnose or manage. They may also be asked to help determine the cause of a fever of unknown origin. Specialists in infectious diseases can practice both in hospitals (inpatient) and clinics (outpatient). In hospit ...
