Acute Poisoning:We live in a world of toxins and potential toxins, and thus we are often just a misstep away from a toxic exposure and its consequences. Even that which is meant to cure can kill. All substances are poisons; there is none which is not a poison. The right dose differentiates a poison and a remedy; exposure to the wrong dose of a medication (whether accidental or not) remains a common form of toxic exposure.

Mycobacterium goodii Infection of a Total Knee ProsthesisMycobacterium goodii infection is uncommon and probablyoccurs via disruption of skin and bone integrity or theintroduction of a foreign body into viscera, namely implantationof a prosthetic device. We describe a case of nosocomial,total knee arthroplasty–associated M goodii infection thatrequired combined antibiotic and surgical therapy for clinicalmanagement. An infection control investigation revealed thatthe source of the organism might have been the water in theoperating room scrub faucets. [Infect Med. 2008;25:522-525]

How to quickly zero in on the diagnosis Hemoptysis: A review of causes, evaluation, and treatment key words: Hemoptysis, Bronchoscopy, Embolizationabstract: Hemoptysis has many causes, including bronchiectasis, lung cancer, and bronchitis. The initial goals of the history and physical examination are to differentiate hemoptysis from epistaxis and hematemesis and then to establish its severity. A variety of signs and symptoms may suggest the underlying cause. For example, hematuria suggests vasculitis or an immunologically mediated disease, such as Wegener granulomatosis or systemic lupus erythematosus. The workup includes chest radiography and measurement of hemoglobin and hematocrit levels, platelet count, international normalized ratio, activated partial thromboplastin time, and creatinine level. Chest CT scanning often identifies sources of bleeding that are not apparent on radiographs and sometimes can be used in conjunction with bronchoscopy. Patients with massive hemoptysis should be hospitalized for rapid evaluation and intervention; treatment may include interventional bronchoscopy, angiography, or embolization.

Making the most of pulmonary function testing in the diagnosis of asthmaAlthough the results of a thorough history and physicalexamination often suggest the diagnosis of asthma, confirmatorytesting is required and may be helpful in more subtlecases. Spirometry before and after bronchodilator administrationis the first step for the initial diagnosis; it also is an importantcomponent of the long-term assessment of asthma control.When the results of spirometry are normal in a patient in whomasthma is suspected, bronchoprovocation challenge testingwith methacholine is generally considered the next diagnosticstep. Numerous alternative methods of bronchoprovocationtesting have been developed, such as the challenge with adenosine5'-monophosphate. Novel methods such as the forced oscillationtechnique and the measurement of exhaled nitric oxidehold promise for more effective diagnosis and monitoringof asthma in the future.

Cerebral Phaeohyphomycosis Caused by Fonsecaea monophora in a Renal Transplant PatientFonsecaea species have been reported as causative agents ofchromoblastomycosis, eumycetoma, and fungal pneumonitis.However, Fonsecaea rarely involves the CNS, with few cases ofcerebral infection reported in the literature. Fonsecaea monophoramay have greater neurotropic potential than other species ofthis genus. We describe a rare presentation of brain abscesscaused by F monophora in an immunocompromised renaltransplant patient. [Infect Med. 2008;25:469-473]

Cryptococcal Meningitis: Review of Current Disease ManagementThe incidence of cryptococcal infections in the HIV-infectedpopulation has diminished because of the effectiveness of anti retroviraltherapy, whereas the incidence in non–HIV-infectedhosts has grown. Despite improvements in antifungal therapy,successful outcomes in the management of cryptococcalmeningitis are dependent on a high index of clinical suspicion,appropriate use of diagnostic assays, early and aggressiveantifungal therapy, and recognition of complications such asincreased intracranial pressure and immune reconstitutionsyndromes. Published guidelines for the care of patients withcryptococcal meningitis are available and may be adapted toindividual patient requirements. Basic and clinical studies areneeded to further define the components of immune protection,optimal therapy in special patient populations, and the recognitionand treatment of complications of cryptococcal meningitis.[Infect Med. 2008;25:11-23]

What are the pulmonary effects of smoking marijuana?Marijuana is the most commonly used illicit drug in the United States. The prevalence of marijuana use has remained stable over the past several years, with 14.6 million persons older than 12 years reporting past-month use in 2005. Given the prevalence of illicit use and interest in the medicinal use of marijuana, an understanding of the potential negative health consequences of marijuana smoking is needed. While tobacco smoking is clearly associated with numerous adverse respiratory complications, including increased cough and wheeze, the development of chronic obstructive pulmonary disease (COPD), lung cancer, and an increased incidence of infections,1-3 the relationship between marijuana and pulmonary disease is controversial, despite similarities in many compounds found in marijuana and tobacco smoke.

Preventing and Treating Influenzaabstract: The keystone of influenza prevention is still vaccination. The 2 available types of influenza vaccine--the inactivated vaccine, which is administered intramuscularly, and the attenuated vaccine, which is delivered via nasal spray--have efficacy rates of 70% to 80%. Unfortunately, only about 65% of persons who should receive the influenza vaccine are, in fact, vaccinated. The neuraminidase inhibitors oseltamivir and zanamivir are 70% to 90% effective in preventing influenza. These antivirals also are effective in reducing the severity of influenza symptoms and the duration of illness when administered within 48 hours of the onset of clinical disease. Some patients have difficulty in self-administering zanamivir because the inhalation process is fairly complicated. Because of the resistance pattern observed in 2005, amantadine and rimantadine are not currently recommended for prophylaxis or therapy. (J Respir Dis. 2007;28(1):21-29)

A reassessment of indications and diagnostic algorithms Bronchoscopy in HIV disease: An update in the era of HAART key words: HIV/AIDS, Bronchoscopy, PCP, Kaposi sarcoma, Lung cancerabstract: The use of fiberoptic bronchoscopy (FOB) in HIV- infected patients has sharply declined since the availability of highly active antiretroviral therapy and the resulting decrease in the incidence of opportunistic infections. Nevertheless, FOB continues to be an important diagnostic tool in this patient population. For example, FOB is useful in evaluating for Pneumocystis jiroveci (formerly carinii) pneumonia (PCP) in patients with CD4+ cell counts of less than 200/µL who have diffuse pulmonary infiltrates and in whom sputum induction has not been performed or is nondiagnostic. It is also useful for evaluating patients who have not responded adequately to empiric therapy for bacterial pneumonia or PCP. Other applications include the visual diagnosis of endobronchial Kaposi sarcoma or the assessment of suspected lung cancer. (J Respir Dis. 2007;28(6): 244-252)

Plague: What You Need to Know NowPlague is caused by Yersiniapestis, a gram-negative, nonmotile,nonsporulating bacillus.It is a zoonotic disease, and rodentsare the primary reservoir.Plague can present as bubonic,pneumonic, or primary septicemic disease.Y pestis is usually transmitted tohumans via the bites of infected fleas,causing the bubonic form of the disease.Primary septicemic and secondarypneumonic disease are muchless common. Primary pneumonicdisease results from aerosol exposureto an infected animal or human withplague pneumonia; however, it too hasbecome uncommon as a natural event.Nonetheless, primary pneumonicplague, or a similar illness, is the mostlikely manifestation following a bioterroristattack.1,2 Despite the substantialinvestment by the former Soviet Unionin this agent as a potential weapon,there is little experience from whichto predict the clinical consequencesof intentional aerosolization of thisorganism.
