Meralgia paresthetica (MP) is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) caused by external compression of the nerve during its course close to the anterior superior iliac spine. We present a case of a patient with acute respiratory distress induced by Legionella pneumonia who was admitted to the intensive care unit (ICU) for mechanical ventilation. In the ICU, the patient received one session of prone position ventilation for 8.5 consecutive hours. At evaluation six months later, the patient reported persistent bilateral numbness of the anterolateral thigh, which he complained had begun right after he woke up at the ICU. He was referred for further neurological and neurophysiological examination and was diagnosed with bilateral MP, a condition never previously described as a complication to mechanical ventilation in prone position in the ICU.

Legionella pneumophila is a common, usually underreported and undiagnosed cause of community acquired pneumonia which can lead to significant morbidity and mortality. Diffuse alveolar hemorrhage rarely have been associated with legionella infection. We present a 61-year-old man with hypertension, diabetes mellitus and obesity admitted with severe acute respiratory distress syndrome. He was found to have Legionella pneumonia with associated diffuse alveolar hemorrhage diagnosed with bronchoscopic sequential bronchoalveolar lavage. He was successfully managed with antibiotics, lung protective strategies and intravenous pulse dose steroids. This patient highlights the unusual association of Legionella infection and diffuse alveolar hemorrhage. Additionally, the case re-enforces the need for early and aggressive evaluation and management of patients presenting with pneumonia and progressive hypoxia despite adequate treatment.

Early antibiotic administration is critical in cases of sepsis and severe community-acquired pneumonia, which is frequently due to Streptococcus pneumoniae, Staphylococcus aureus, Legionella species, or influenza. We describe the case of a 29-year-old previously healthy man who presented to an urban emergency department (ED) in the North Central U.S. with fever, hip pain, severe hypoxemia, and diffuse pulmonary infiltrates. He was intubated and received piperacillin/tazobactam, levofloxacin, vancomycin, and oseltamivir; given his fulminant presentation and predicted high mortality, doxycycline, methylprednisolone, and amphotericin B were also administered empirically in the ED. A respiratory culture eventually grew Blastomyces dermatitidis, and the patient survived. Severe acute respiratory distress syndrome due to fulminant pneumonitis carries a high mortality. Faced with this scenario and no room for error, it is important that the emergency physician cover for all possible pathogens, including zoonotic bacteria and endemic fungi.

The water crisis in Flint, Michigan raised national awareness about lead- tainted drinking water, particularly its harm to children and pregnant and lactating women. However, according to recent findings, there may be another by-product of this man-made crisis. Failure to use anticorrosive material in the water, a practice mandated by the 1978 Clean Water Act, is being linked to an outbreak of Legionnaires' disease, an illness detrimental primarily to adults over 65 years of age. While Legionnaires' disease is relatively rare, it is also likely to remain undiagnosed. Clinicians, therefore, are urged to consider this diagnosis in adults with pneumonia that does not respond to typical antibiotic treatment, and in newborns with respiratory distress along with other non-typical symptoms as well as those who have had water births or who were exposed to ultrasonic, cool-mist humidification.

Legionella community-acquired pneumonia necessitating veno-venous extracorporeal membrane oxygenation for severe acute respiratory distress syndrome has been reported in adults. However, few options remain in cases of refractory hypoxemia on veno-venous extracorporeal membrane oxygenation. Herein, we describe adjunctive extended therapeutic hypothermia for refractory hypoxemia despite veno-venous extracorporeal membrane oxygenation for successful management of severe acute respiratory distress syndrome secondary to Legionella.

L. pneumophila is an unusual cause of pneumonia with a prevalence of 2.7%, and it is even more uncommon in pregnancy. To date, only 11 cases of Legionnaire's Disease in pregnancy have been reported, though this small number could possibly be attributed to underdiagnoses and under documentation. Case Presentation: In this paper, we present a 31-year-old Hispanic female, gravida 4, para 1 from the southwest United States who presented with a 3-week history of fever, worsening cough, dyspnea on exertion, and hypoxemia. Chest x-ray showed bibasilar infiltrates, with positive serology for Legionella IgM and IgG (1:250 and 1:640 respectively), as well as positive urinary antigen. Despite appropriate treatment with azithromycin 500 mg, she continued to have dyspnea and mild respiratory distress. Conclusion: Upon follow up, mother and fetus initially remained stable without any signs of sequelae from Legionnaire's disease, but the patient miscarried 5 weeks after the second admission to the hospital. The chest x-ray eventually cleared up after almost 21 days of azithromycin.
