Tetanus Learning Objective: At the end of this unit the student will be able to 1 order apcalis sx visa. Design appropriate methods of prevention for tetanus Definitions Tetanus is a neurologic disease characterized by increased muscle tone and spasms caused by toxin released from the bacteria Clostridium tetani buy discount apcalis sx line. They are also resistant to different disinfectant and even to boiling for less than 20 minutes trusted 20mg apcalis sx. Epidemiology Tetanus occurs sporadically and almost always affects non-immunized persons. Partially immunized persons or fully immunized individuals who fail to maintain adequate immunity are also affected. It also occurs more frequently in warmer climates, during summer months and in males. Neonates and young children are affected more in developing countries where immunization programs are not comprehensive. Most cases of tetanus follow injuries especially during farming, gardening or other outdoor activities. Tetanospasmin may also block neurotransmitter release at the neuromuscular junction and produce weakness or paralysis. Generalized tetanus occurs when toxin enters into blood stream and lymphatic to affect distant nerve endings. Clinical Manifestations The incubation period (time between the injury and first symptom) of tetanus is about 7 10 days but it may range from 1 day to 2 months. The shorter the incubation period and period of onset, the more severe the disease becomes. There are different forms of tetanus: neonatal, generalized and localized tetanus. Generalized Tetanus The median time of onset after injury is seven days; but could occur as early as with in three days. Usually the fist symptom is increased tone in the masseter muscle (trismus, or lockjaw) and patient is unable to open his mouth. Patients may come with wide ranges of wound severity, although most have trivial or healed wound. Neonatal tetanus: Occurs in neonates of non-immunized mother and those delivered in unhygienic condition. Treatment The goals of treatment are To eliminate source of toxin Neutralize unbound toxin and Prevent muscle spasm. These procedures are required for hypoventilation caused by laryngospasm or over sedation or to avoid aspiration. Specific Treatment; Antibiotic treatment: This helps to eradicate the vegetative bacteria, not the toxin. Erythromycin and clindamycin are alternatives in patients allergic to penicillins. Control of muscle spasms: Diazepam and Chlorpromazine are given 6 hourly, alternatively. Refer people who were bitten by rabied animals to hospitals for post exposure prophylaxis 10. Humans are occasionally infected by wild animals like foxes and bats, but domestic dogs are responsible for more than 90% of human cases worldwide. Patients may have fever, irregular pupils, salivation, perspiration and postural hypotension. Later the white cell count is usually moderately elevated, but it may as well be normal. However, the diagnosis of rabies rests on identification of the virus or serologic tests. Therefore anyone with history of domestic or wild animal bite should be taken seriously. Post exposure prophylaxis: should be considered in people who had physical contact with saliva or secretions of infected animals or bitten by unprovoked animal e. Post exposure prophylaxis of rabies includes: Rigorous cleansing and treatment of the wound Administration of rabies vaccine together with anti-rabies immunoglobulin. Anthrax Learning Objective: At the end of this unit the student will be able to 1. Design appropriate methods of prevention and control of anthrax Definition: anthrax is an infection that is caused by Bacillus anthracis. It mainly affects herbivorous animals but humans are infected by contact with the causative agent from infected animals, by contact, ingestion or inhalation. Epidemiology: Anthrax is more common in herbivorous animals like cattle, sheep and goats. Humans may acquire anthrax from agricultural sites through contact with animals like butchering and feeding or industrial sites through exposure to contaminated hides, wool or bones. It also produces anthrax toxin, which causes edema and inhibition of polymorphonuclear leucocyte function. Cutaneous anthrax: The lesions are more common on exposed areas like face, neck and extremities. This will become papular and pustular which then forms a central necrotic ulcer (black eshcar) with surrounding edema; it is painless. Inhalational anthrax (wool sorters disease): This form resembles severe viral respiratory disease and thus diagnosis is difficult. Treatment Cutaneous anthrax Can be treated with crystalline penicillin 2 million units 6 hourly until edema subsides then oral penicillin for 7-10 days. Design appropriate methods of prevention and control of brucellosis Definition: Brucellosis is a zoonotic disease caused by Brucella species, which is characterized by remittent type of fever and multi-organ involvement. They are small aerobic gram-negative bacilli; they are non-motile and facultative intracellular parasites. In communities where brucellosis is endemic, it occurs in children and family members of infected persons are at risk. Commonly affected are farmers, meat-processing workers, veterinarians, and laboratory workers. Pathogenesis: In the blood Brucella is ingested by polymorphonuclear leukocytes and macrophages but they resist intracellular phagocytosis. Severity of the disease is largely determined by the outcome of pathogen-phagocyte interaction. In infected organs there will be inflammatory responses or noncaseating granulomas. Clinical manifestations and complications: Brucellosis is a systemic illness and its manifestations mimic other febrile illnesses. Diagnosis The combination of history of exposure, clinical features and significantly raised levels of Brucella agglutinin confirms the diagnosis of active brucellosis. Treatment The combination of doxycycline and aminoglycoside (gentamicin, or streptomycin) for 4 weeks followed by the combination of doxycycline and rifampin for 4 to 8 weeks is the most effective treatment modality.
