Additional findings that may raise ones concerns for the diagnosis of meningitis include seizures generic modafinil 200mg without prescription sleep aid cvs, focal neurologic deficits, rash, septic arthritis, papilledema and photophobia. Seizures have been described in 15% to 30% of patients and are most commonly associated with infections due to Streptococcus pneumoniae. Focal neuro- logical deficits are seen in 10% to 35% of patients with Listeria monocytogenes as part of a rhombencephalitis syndrome including ataxia with or without nystagmus, and cranial nerve palsies. Neisseria meningitidis may cause palpable purpura in 11% to 64% of patients, and concomitant septic arthritis in 7% to 11%. Papilledema and/or photophobia are rarely present, having been described in less than 5% of cases. Although no randomized controlled trial exists to prove it, the best experimental and observational data suggest that time to antibiotics has a profound effect on clinical outcomes. Therefore, our goal in the emergency department is to maintain a high index of suspicion and not delay treatment while diagnostic studies are being completed. Pneumococcal infections, however, will typically remain culture positive up to 4 to 10 hours after administration of parenteral antibi- otics. Importantly, Gram stains can positively identify an organism in 10% to 15% of patients who have sterile cultures after antibiotic administration. Identification of the causative organism allows clinicians to safely narrow the spectrum of antimicrobial therapy. However, in the emergency department we are often unable to know with certainty what organism will eventually be identified, and are therefore required to initiate empiric therapy on the basis of epidemiologic data and local resistance patterns. As Gram stain results are typi- cally available 1 to 2 days before culture results, it is helpful to know the Gram-stain pattern of the most common organisms. The presence of gram-positive diplococci suggests Streptococcus pneumoniae infection, while gram-negative diplococci suggest Neisseria meningitidis infection. Small pleomorphic gram-negative coccobacilli suggests Haemophilus influenzae, while gram-positive rods and coccobacilli suggest Listeria monocytogenes infection. Unfortunately, despite all of these tests it can still be quite difficult to distinguish between the possible causes of meningitis (bacterial, viral, tubercular, neoplasms, autoimmune, etc) (Table 30–2). Ceftriaxone or cefotaxime at a dose of 2 g is typically recommended in the United States. As a result of an increasing worldwide prevalence of drug resistant Streptococcus pneumoniae, most authorities now recommend a dose of vancomycin along with the third-generation cephalosporin until a resistance profile can be obtained. Patients who are older than 50 years of age, alcoholic, or immunocompromised are at higher risk for additional organisms including Listeria monocytogenes, Hae- mophilus influenzae, and aerobic gram-negative bacilli, and should therefore have ampicillin added to the empiric antibiotic regimen. Patients less than 1 month of age are at risk for infection with Streptococcus agalactiae, Klebsiella sp, E coli, and L monocytogenes and require yet another empiric regimen (Table 30–3). In addition to adequate antimicrobial therapy, a number of recent studies have shown improved outcomes with adjunctive dexamethasone either before or with the first dose of antibiotics. If antibiotics have already been initiated as an outpatient or before steroid administration, the subsequent addition of dexamethasone has no demonstrated efficacy and may cause harm. For most patients, a single dose of dexamethasone is unlikely to be harmful, and in general most authorities recommend that if you are giving antibiotics for suspected bacterial meningitis, it should be preceded or accompanied by a dose of dexamethasone. Once a patient is diagnosed with bacterial meningitis, family members and close contacts (such as this patient’s roommate) are often concerned about whether they should receive antibiotic prophylaxis to prevent them from developing a similar infection. Antibiotics for close contacts of patients with meningitis due to Haemophilus influenzae are no longer rec- ommended if all contacts 4 years of age or younger are fully vaccinated against Hib disease. Given the high morbidity and mortality of meningococcal infections, vacci- nation against N meningitidis is recommended for freshmen college students who live in dormitories, as they are at moderately increased risk of contracting this disease. Neuroimaging is indicated in this patient prior to lumbar puncture given his altered mental status. It is expected that one would obtain blood cultures and administer dexamethasone prior to the antibiotics in this case. All adults with suspected bacterial meningitis get a third-generation cepha- losporin and most institutions advocate for vancomycin to cover drug-resistant Streptococcus pneumoniae. Although the triad in the question is considered classic, studies have found that it is only present in less than half of the cases. If headache is added to the other 3, then at least 2 of the 4 symptoms are present in approximately 95% of patients. Initial antimicrobial therapy in adults should include a third-generation cephalosporin and vancomycin to cover drug-resistant S pneumoniae.
Tamponade may develop if pressure from the effusion is great enough to significantly impair cardiac filling purchase modafinil 200mg with amex kirkland sleep aid 96. Emergent treatment consists of immediate pericardial drainage by needle aspiration. A high suspicion must be maintained for aneurysm/dissection and pulmonary embolism to avoid missed diagnosis and potentially catastrophic outcomes for the patients. This entity involves a traumatic mucosal disruption usually located either at the gastroesophageal junction or gastric cardia. Deeper tears of the esophageal mucosa may manifest as intramural esophageal hematomas which can develop into full esophageal perforations with delayed rupture during the inflammatory weaken- ing that accompanies healing. Spontaneous pneumomediastinum without evidence of gastrointestinal or pleu- ral source has been reported. It is usually seen in patients who have suffered from a valsalva episode against a closed glottis such as may occur during powerful coughing. Chest pain is universal and on exam a loud crunching sound may be heard as mediastinal air is squeezed by the beating heart (Hamman crunch). It is hypoth- esized that the mediastinal air arises from pulmonary interstitial emphysema caused by bronchoalveolar barotrauma. Nonetheless, the diagnosis of pneumomediastinum requires a diligent and exhaus- tive search for both pulmonary and gastrointestinal sources. Causes of breast pain include infectious etiologies, mastitis or abscess, benign lumps, cysts, or inflammatory carcinoma. Physical examination may reveal an asymmetric breast mass with or without signs of significant local induration, erythema, and tenderness. Intravenous analgesics, antibiotics and early surgical consultation are appropriate. As such, it is imperative that early primary care follow-up be arranged for patients given this diagnosis. Odyno- phagia, dyspnea, tachypnea, cyanosis, fever, and shock may all develop thereafter. The diagnosis of Boerhaave Syndrome may be delayed because the clinical presentation may not be typical and causes are broad: childbirth, defecation, seizures, and heavy lifting. Common misdiagnoses include: myocardial infarction, pancreatitis, lung abscess, pericarditis, and spontaneous pneumothorax. Gastrografin should be used instead of barium to avoid severe medi- astinal and intra-pleural inflammatory reactions when doing contrast studies to locate the site of esophageal perforation.

The cardiac examination reveals normal rate, no murmurs or rubs, and a positive S4. The abdomen is soft and nontender to palpation, with hypoactive bowel sounds and no organomegaly. The physi- cal examination reveals moderate jugular venous distension, some minor bibasilar rales, and lower extremity edema.
