At least five agents have been identified as causes of viral hepatitis. Hepatitis a virus (hay) has no vertical transmission and will not be discussed. Hepatitis b virus (hbv). Hepatitis c virus (hcv) (post-transfusion non-a, non-b [nanb] hepatitis virus). Hepatitis d virus (hdv). And hepatitis e virus (hey) (enteric, epidemic nanb hepatitis virus). Hdv, also referred to as the delta agent, is a defective virus that requires coinfection or superinfection with hbv. Hdv is coated with hepatitis b surface antigen (hbsag). Specific antibodies to hdv can be detected in infected individuals, but there is no known therapy to prevent infection in exposed hbsag-positive patients. For the newborn, therapy directed at the prevention ofhbv infection should also prevent hdv infection because coinfection is required. A.. Hbv (perinatal and congenital). This dna virus is one of the most common causes of acute and chronic hepatitis worldwide. 1. Epidemiology. In endemic populations, the carrier state is high, and perinatal transmission is a common event. The risk of chronic infection is inversely infectious diseases i 611 proportional to age, with a 90% carriage rate following infection in neonates. The overall incidence of hbv infections in the united states is relatively low. Approximately 300,000 infections occur yearly, with 250 deaths from fulminate disease. The incubation period for hbv infection is approximately 120 days (range 45-160 days). High-risk groups for hbv infection in the united states include the following. A. Persons hom in endemic areas. Alaskan natives and pacific islanders and natives of china, southeast asia, most ofafrica, parts of the middle east, and the amazon basin. Descendants of individuals from endemic areas. B. Persons with high-risk behavior. Men who have sex with men, intravenous drug use, and multiple sex partners. C. Oose contacts with hbv-infected. Persons (sex partners, family members). D. Selected patient populations, particularly those receiving multiple blood or blood product transfusions.

Levels between 20 to 50 percent associated with mild-to-moderate bmd. Motor neuron disease als t e pathogenesis o sporadic orms o motor system diseases is unknown. However, 10 percent o als cases are caused by autosomal dominant gene mutations. Wenty- ve percent o als cases caused by genetic mutations are due to mutations in the gene coding or cytosolic enzyme cu-zn superoxide dismutase. Neuromuscular junction congenital mg congenital myasthenic syndrome is a group o conditions characterized by muscle weakness worsened with physical exertion. Symptoms usually begin with weakness in acial muscles, ptosis, and dysphagia leading to eeding di culties. Mutations in many genes lead to congenital myasthenic syndrome. Mutations in the chrne gene are responsible or more than hal o all cases. A large number o cases are also caused by mutations in the rapsn, chat, colq, and dok7 genes. 259 periodic paralyses hyperkalemic periodic paralysis hyperkalemic periodic paralysis is an autosomal dominant disorder due to mutations in the scn4a gene. T e scn4a protein orms channels that control the ow o sodium ions into these cells. Mutations in the scn4a gene alter the unction o sodium channels, leading to increased levels o sodium in the muscle cell. An increase in sodium triggers the release o potassium rom muscle cells, causing increasing sodium channels to open. T ese changes in ion transport reduce muscle contraction and result in episodes o muscle weakness or paralysis. Hypokalemic periodic paralysis hypokalemic periodic paralysis is an autosomal dominant disorder due to mutations in the cacna1s and scn4a genes. T e cacna1s protein transports calcium ions into cells required or contraction o skeletal movement, while the scn4a protein transports sodium ions. Mutations in the cacna1s or scn4a gene alter the structure and unction o calcium or sodium channels. Mutations in these proteins ultimately lead to episodic muscle weakness or paralysis. General principles of management respiratory failure and autonomic x dysfunction in patients with progressive generalized weakness in the setting o neuromuscular disorders, it is essential to recognize the signs o impending respiratory ailure. Delayed intubation can lead to higher risk o aspiration pneumonia and increased morbidity. T e high incidence o respiratory complications is due to the requent involvement o respiratory and pharyngeal muscles in patients with neuromuscular diseases. Progressive spine de ormities (eg, kyphoscoliosis) commonly occur in patients with progressive muscular dystrophies, and congenital myopathies can cause restrictive lung diseases and aggravate chronic respiratory insu ciency. Clinical examination should be ocused on assessing or signs o respiratory distress. T e examination may reveal use o accessory muscles, generalized weakness, tachycardia, staccato speech (pausing between words while speaking), dysarthria, and inability to clear secretions. T e inability or a patient to li their head o the bed may be a sign o worsening diaphragmatic weakness. Singlebreath-count test per ormed at the bedside tests the ability to count out loud a er maximal inspiration. Patients with normal respiratory unction can reach up to 50. Less than 15 correlates with severely impaired vital capacity. Serial monitoring o vital capacity is the best studied ancillary 260 ch a pt er 16 tool in predicting neuromuscular respiratory ailure, and spirometry should be checked 2–4 times a day. When vital capacity drops less than 15 ml/kg, intubation is generally required. Measuring maximum inspiratory pressure (mip) and maximum expiratory pressure (mep) can also be measured. T e “20/30/40 rule” o (vc < 20 ml/kg. Pimax < –30 cm h 2o and pemax < 40 cm h 2o levels) is concerning or impending neuromuscular respiratory ailure.

By using this rule, providers can identi y predict patients that may require close respiratory monitoring and potential mechanical ventilation. Absolute criteria or intubation include impaired consciousness, respiratory or cardiac arrest, arrhythmias, blood gas alterations such as hypercarbia, and bulbar dys unction leading to aspiration.
