These infections are rapidly progressing entities that demand immediate therapeutic intervention. If the infection is diagnosed late in the course, pts may present with cranialnerve palsies or cavernous venous sinus thrombosis. The most common clinical syndromes are bacteremia, pneumonia, and soft tissue infections, mainly manifesting as ecthyma gangrenosum. Severe or life-threatening infections are generally treated with two antibiotics to which the infecting strain is sensitive, although evidence that this course is more efficacious than monotherapy has been lacking since the introduction of more active -lactam agents. Central venous line infection (most often in cancer pts) and ecthyma gangrenosum in neutropenic pts have been described. Miscellaneous Organisms Melioidosis is endemic to Southeast Asia and is caused by Burkholderia pseudomallei. Neutropenic host Endocarditis Pneumonia Bone infection, malignant otitis externa Central nervous system infection Eye infection Keratitis/ulcer Endophthalmitis Resistance during therapy is common. Levofloxacin may be an alternative, but there is little published clinical experience with this agent. These diseases present as acute or chronic pulmonary or extrapulmonary suppurative illnesses or as acute septicemia. Epidemiology Legionella is found in fresh water and human-constructed water sources. Outbreaks have been traced to potable-water supplies and occasionally cooling towers. The organisms are transmitted to individuals primarily via aspiration but can also be transmitted by aerosolization and direct instillation into the lung during respiratory tract manipulations. Pts who have chronic lung disease, who smoke, and/or who are elderly or immunosuppressed are at particularly high risk for disease. Diarrhea, confusion, high fevers, hyponatremia, increased values in liver function tests, hematuria, hypophosphatemia, and elevated creatine phosphokinase levels are documented more frequently than in other pneumonias. The heart is the most common extrapulmonary site of disease (myocarditis, pericarditis, and occasionally prosthetic valve endocarditis). Prognosis Mortality approaches 80% among compromised hosts who do not receive timely therapy. Among immunocompetent hosts, mortality can approach 31% without treatment but ranges from 0 to 11% if pts receive appropriate therapy. Brucellosis is transmitted via ingestion, inhalation, or mucosal or percutaneous exposure; the disease in humans is usually associated with exposure to infected animals or their products in either occupational settings. Brucellosis often presents with one of three patterns: a febrile illness similar to but less severe than typhoid fever; fever and acute monarthritis, typically of the hip or knee, in a young child (septic arthritis); or long-lasting fever and low back or hip pain in an older man (vertebral osteomyelitis). Brucella infection can cause lymphadenopathy, hepatosplenomegaly, epididymoorchitis, neurologic involvement, and focal abscess. Diagnosis Laboratory personnel must be alerted to the potential diagnosis to ensure that they take precautions to prevent occupational exposure. Brucellosis must be distinguished from tuberculosis; if this distinction is not possible, the regimen should be tailored to avoid inadvertent monotherapy for tuberculosis (see below). Brucellosis tends to cause less bone and joint destruction than tuberculosis (Table 98-1).

This chapter will discuss the clinical features and treatment of the various aspects of traumatic brain injury, the etiology of these clinical features, and the differential diagnosis between traumatic brain injury and concussion. Clinical features and treatments In considering the clinical features (and their treatments) of traumatic brain injury, it is convenient to divide them into two groups, namely an acute phase and a chronic phase. The acute phase, from a neuropsychiatric point of view, is often dominated by a delirium; as the confusion clears, patients gradually enter into the chronic phase, which in turn may be characterized by numerous sequelae, including cognitive deficits that may, at times, be severe enough to constitute a dementia. This delirium, in addition to such characteristic symptoms as confusion, disorientation, and decreased short-term memory, is also often marked by hallucinations, delusions, and, especially, agitation, which is seen in the majority of cases (Rao and Lyketsos 2000; van der Naalt et al. It must be borne in mind that although the delirium in such cases is generally due to the intracranial injuries directly caused by the trauma, that other factors, as discussed in Section 5. Toxicity from such medications as opioids, baclofen, anticholinergics, metoclopramide, and even amantadine must be considered, along with metabolic factors, such as hyponatremia, hypoglycemia, hypomagnesemia, and systemic effects of infections, such as pneumonia. Consideration may also be given to the effects of global cerebral ischemia secondary to severe hypotension and, in those with fractures of long bones, to the fat embolism syndrome. In comatose patients, intracranial pressure monitoring is often indicated, and treatment with intravenous sedation, mannitol, and other agents may be required to reduce pressure. Treatment of delirium, in all cases, involves simple environmental measures designed to reduce confusion. These include, whenever possible, having the patient in a quiet room, with a window. Sleep is essential and consequently the room should be darkened and very quiet at night, and all non-emergency procedures. In cases where these environmental measures are ineffective, pharmacologic treatment may be considered with either an antipsychotic or, in certain emergent cases, lorazepam. Antipsychotics are indicated for treatment of hallucinations or delusions, and are also effective for agitation. A secondgeneration agent, such as risperidone, is often used, and, in practice quetiapine and olanzapine are also utilized. Repeat doses, in approximately similar milligram amounts, may then be given every hour or so until the patient is calm, limiting side-effects occur, or a maximum dose is reached: rough guidelines for dose maxima are 5 mg for risperidone, 150 mg for quetiapine, 20 mg for olanzapine, and 20 mg for haloperidol. In cases when the patient responds satisfactorily, a regular daily dose is ordered for the next day (with the total daily dose approximately equivalent to the total required initially), divided into two or three doses. Provision is also made for further as-needed doses, with the total daily dose being adjusted according to the amount needed in p. The eventual maintenance dose is then continued until the patient has been stable for a significant period of time, at which point it may be gradually tapered. Lorazepam is very commonly used, and given the rapidity of its effectiveness when given intravenously, has a place in emergent situations; however, given that lorazepam may also worsen confusion, it is appropriate to substitute another agent as soon as this is practical. Once patients have been stabilized, general rehabilitation efforts may be started, including physical, speech, and occupational therapy. Eventually, most patients are transferred to a specialized rehabilitation facility, where these general efforts are continued. The Glasgow Coma Scale (Teasdale and Jennett 1974) is designed for evaluating patients in the acute phase, and involves assessing three clinical features: eye opening, motor response, and verbal response, with, as noted in Table 7. Patients with total scores of 8 are said to have a severe injury, those with scores from 9 to 12, a moderate injury, and those with scores of from 13 to 15, a mild injury. Post-traumatic seizures may occur during the acute phase, and these are discussed further, below. Chronic phase As the delirium gradually clears, almost all patients will be left with one or more chronic sequelae (Rao and Lyketos 2000), and these are discussed below, beginning with cognitive deficits, which are almost universal. In some cases these may be quite mild and not terribly limiting; however, in others they amount to a clear, and disabling, dementia. Most patients show improvement over the first 6 months, with some further, but not as impressive, gains over the next 6 months: however, after 12 months, little further spontaneous recovery can be expected. Importantly, in assessing patients with cognitive deficits it is critical to check for the presence of depression, which, in and of itself, may cause cognitive impairment.

Infection requires ingestion of a relatively large inoculum (compared with other pathogens) symptoms kidney failure naltrexone 50 mg low price. A single dose of an antibiotic can be used in conjunction: doxycycline (300 mg) treatment zona generic 50mg naltrexone amex, ciprofloxacin (30 mg/kg treatment alternatives buy naltrexone 50mg overnight delivery, not to exceed 1 g), or azithromycin (1 g). After an incubation period of 4 h to 4 days, watery diarrhea, abdominal cramps, nausea, vomiting, and occasionally fever and chills develop. In the United States, >90% of outbreaks of nonbacterial gastroenteritis are caused by noroviruses. Thus, although the fecal-oral route is the primary mode of transmission, aerosolization, fomite contact, and person-to-person contact can also result in infection. Infections with Noroviruses and Related Human Caliciviruses Only supportive measures are required. Large quantities of virus are shed in the stool during the first week of infection, and transmission takes place both via the fecal-oral route and from person to person. Vomiting often precedes diarrhea (loose, watery stools without blood or fecal leukocytes), and about one-third of pts are febrile. Disease in developing countries occurs in younger children and is more severe than in industrialized countries; further study is needed before global recommendations for vaccine use can be issued. Cysts are ingested from the environment, excyst in the small intestine, and release flagellated trophozoites. People at the extremes of age, those newly exposed, and pts with hypogammaglobulinemia are at increased risk-a pattern suggesting a role for humoral immunity in resistance. Disease ranges from asymptomatic carriage (most common) to fulminant diarrhea and malabsorption. Diagnosis Giardiasis can be diagnosed by parasite antigen detection in feces and/or examination of several samples from freshly collected stool specimens, with concentration methods used to identify cysts (oval, with four nuclei) or trophozoites (pear-shaped, flattened parasites with two nuclei and four pairs of flagella). In cases of treatment failure, document continued infection before re-treatment, and seek possible sources of reinfection. Person-to-person transmission of infectious oocysts can occur among close contacts and in day-care settings. Acute infection can begin suddenly with fever, abdominal pain, and watery, nonbloody diarrhea and can last for weeks to months. Conditions that reduce gastric acidity or decrease intestinal integrity increase susceptibility to infection. Nontyphoidal salmonellae most commonly cause gastroenteritis, invading the large- and small-intestinal mucosa and resulting in massive polymorphonuclear leukocyte infiltration. Disease results from ingestion of contaminated food or water and is rare in developed nations. Physical findings include rash ("rose spots"), hepatosplenomegaly, epistaxis, and relative bradycardia. Nontyphoidal salmonellosis: the incidence of nontyphoidal salmonellosis in the United States is 14. The main mode of transmission is from contaminated food products, such as eggs (S.
