Bacterial meningitis Bacterial meningitis is a very common cause of morbidity purchase combivent 100mcg free shipping, mortality and neurological compli- cations in both children and adults, especially in children. It has an annual incidence of 4 6 102 Neurological disorders: public health challenges cases per 100 000 adults (dened as patients older than 16 years of age), and Streptococcus pneumoniae and Neisseria meningitidis are responsible for 80% of all cases (20). In developing countries, overall case-fatality rates of 33 44% have been reported, rising to over 60% in adult groups (21). Bacterial meningitis can occur in epidemics that can have a serious impact on large populations. The highest burden of meningococcal disease occurs in sub-Saharan Africa, which is known as the meningitis belt, an area that stretches from Senegal in the west to Ethiopia in the east, with an estimated total population of 300 million people. The hyperendemicity in this area is at- tributable to the particular climate (dry season between December and June, with dust winds) and social habits: overcrowded housing at family level and large population displacements for pilgrim- ages and traditional markets at regional level. Because of herd immunity (whereby transmission is blocked when a critical percentage of the population had been immunized, thus extending protection to the unvaccinated), the epidemics occur in a cyclical fashion. Meningitis is characterized by acute onset of fever and headache, together with neck stiffness, altered consciousness and seizures. Antibiotic treatment is effective in most cases but several neurological complications can remain, such as cognitive difculties, mo- tor disabilities, hypoacusia and epilepsy. In a recent review, treatment with corticosteroids was associated with a signicant reduction in neurological sequelae and mortality (22). Progress is more likely to come from investigations into preventive measures, especially the use of available vaccines and the development of new vaccines. Meningitis caused by Haemophilus inuenzae type B has been nearly eliminated in developed countries since routine vaccination with the H. The approval in 2005 of a conjugate meningococcal vaccine against serogroups A, C, Y and W135 is also an important advance that may decrease the incidence of this devastating infection. Local and nationwide surveillance, in- cluding the laboratory investigation of suspected cases, is critical for early detection of epidemics and the formulation of appropriate responses. Tetanus Tetanus is acquired through exposure to the spores of the bacterium Clostridium tetani which are universally present in the soil. The disease is caused by the action of a potent neurotoxin produced during the growth of the bacteria in dead tissues, e. Tetanus is not transmitted from person to person: infection usually occurs when dirt enters a wound or cut. At the end of the 1980s, neonatal tetanus was considered a major public health problem. A worldwide total of 213 000 deaths were estimated to have occurred in 2002, 198 000 of them concerning children younger than ve years of age (23). Unlike poliomyelitis and smallpox, the disease cannot be eradicated because tetanus spores are present in the environment. Once infection occurs, mortality rates are extremely high, especially in areas where appropriate medical care is not available. Neonatal tetanus can be prevented by immunizing pregnant women and improving the hygienic conditions of delivery. Adult tetanus can be prevented by immunizing people at risk, such as work- ers manipulating soil; others at risk of cuts should be also included in the prevention measures. The adult tapeworm (at, ribbon-like, approximately 2 4 m long) lives only in the small intestine of humans, who acquire it (taeniasis) by eating undercooked pork containing the viable larvae or cysticerci. A tapeworm carrier passes microscopic Taenia eggs with the faeces, contaminating the close en- vironment and contacts and causing cysticercosis to pigs and humans. Human beings therefore acquire cysticercosis through faecal oral contamination with T. Thus, vegetar- ians and other people who do not eat pork can acquire cysticercosis. Recent epidemiological evidence suggests that the most common source of infective eggs is a symptom-free tapeworm carrier in the household. Therefore, cysticercosis should be seen as a disease mostly transmitted from person to person (25). In addition, because of high immigration rates from endemic to non-endemic areas and tourism, neurocys- ticercosis is now commonly seen in countries that were previously free of the disease. Despite the advances in diagnosis and therapy, neurocysticercosis remains endemic in most low income countries, where it represents one of the most common causes of acquired epilepsy (27). Many more patients survive but are left with irreversible brain damage with all the social and economic consequences that this implies (28). Several articles from different countries in Latin America consistently showed an association between around 30% of all seizures and cysticercosis (29). Accurate diagnosis of neurocysticercosis is based on assessment of the clinical and epidemio- logical data and the results of neuroimaging studies and immunological tests (30). Therapy must be individualized according to the location of parasites and the degree of disease activity: this implies symptomatic therapy, anticysticidal drugs (albendazole/praziquantel), antiepileptic drugs and surgical treatment of complications such as hydrocephalus. Neurocysticercosis is one of a few conditions included in a list of potentially eradicable infec- tious diseases of public health importance (31).

The clinical impact of sarcoidosis depends on which organs are involved and the extent of the granulomatous inflammation. Once the diagnosis is confirmed the patient should be evaluated as to the extent and severity of disease and then followed at regular intervals. Symptoms should prompt evaluation of the relevant organ(s) and treatment would be based on the severity of that involvement. Even if asymptomatic, all sarcoid patients should have their lungs, eyes, heart and calcium levels evaluated at the time of initial diagnosis and probably annually thereafter. Treatment of sarcoidosis is indicated when organ dysfunction is clinically significant. In sarcoidosis, oral corticosteroids are used to improve function of the involved organ (assessed by pulmonary function tests and oxygen levels) thereby, providing symptom relief and an improved quality of life while possibly preventing disease progression. However, these goals must be balanced by the potential for serious side effects from the long-term use of corticosteroids and the lack of certainty that disease progression can be influenced over the long-term. For this reason, it is not recommended to treat asymptomatic patients with minimal organ involvement (ex. Indications for treatment with oral corticosteroids would include lung involvement with impaired gas exchange (reduced diffusion and hypoxemia), eye disease that has failed to improve with topical treatment, cardiac involvement (e. A typical starting dose is 40 mg of prednisone, or its equivalent, daily or on alternate days. Patients are followed carefully and those with objective improvement begin to gradually and slowly taper or reduce their corticosteroid dose over the next 6 to 12 months to as low a level as tolerated without return of symptoms or organ dysfunction. Many patients will have a good clinical response and objective measures of improved organ function, allowing corticosteroids to be discontinued. In some patients, either during initial treatment or re-treatment with corticosteroids, side effects are intolerable or treatment response is inadequate. Hydroxychloroquine is a first-line or second-line drug used when sarcoidosis is the cause of isolated skin, bone or calcium problems. Rarely, (approximately 1% of patients) develop severe life-threatening pulmonary disease (severe hypoxemia and pulmonary hypertension) despite aggressive use of immunosuppressive medications and may be candidates for lung transplantation. This review was accomplished as follows: (a) all films were routinely interpreted by a board-certified radiologist without knowledge that a study was underway; and (b) if the radiographic findings as evaluated by the radiologist were abnormal, the chest radiograph was reviewed by our board-certified pulmonologist, who was aware that a pulmonary surveillance study (for all lung disease, not just sarcoidosis) was underway. Fourth, all disability leave and retirement applications were reviewed for sarcoidosis cases. To ensure the latter, an independent radiologist, without knowledge of the study or diagnosis in question, reviewed the pre-employment chest radiographs in suspected cases. Pre- and post-9/11/01, the majority of biopsies were obtained by mediastinoscopy of intra-thoracic lymph nodes. Although, shortness of breath on exertion was the most common symptom, (nearly 50% of the cases) it was mild and most had normal pulmonary functions. None had evidence for asthma or airway hyperreactivity on bronchodilator testing and cold air challenge testing, and only one had abnormal gas exchange with a reduced diffusion of oxygen. Three patients (14%) were treated with oral corticosteroids; two cases with shortness of breath and abnormal pulmonary function, and one case with joint aches and normal pulmonary function. After 12 to 18 months, all three fire fighters were off medication, asymptomatic, and returned to full fire fighter duties without further exacerbations. Nearly identical increases in incidence rates were seen in patients whose diagnostic evaluation was initiated due to an abnormal chest radiograph as compared to those initiated due to symptoms. Only 35% presented with Stage 0 or Stage I sarcoidosis on chest radiographic imaging. Asthma-like symptoms were now common, with nearly 70% reporting cough, shortness of breath, chest tightness and/or wheezing exacerbated by exercise/irritant exposure or improved by bronchodilators. Pulmonary functions confirmed reversible airways obstruction in at least a third of these cases. New-onset airway obstruction was evident on spirometry in four (15%) patients, two of whom had a bronchodilator response. Airway hyperreactivity was assessed in 21 of 26 patients by either methacholine or cold air challenge and positive results were found in eight (38%). What remained similar to pre-9/11 was that gas exchange abnormalities remained rare with abnormal diffusion of oxygen evident in only two patients (8%). Pulmonary function improved in the two patients with abnormally low diffusion of oxygen (both treated with oral corticosteroids) and remained stable in the other 24 patients. Chest imaging abnormalities remained unchanged in 12 (two received oral corticosteroids), improved in four (two received oral corticosteroids), and resolved in six patients (two received oral corticosteroids).
