Brachial neuritis with bilateral hemidiaphragmatic paralysis has been reported in two previous cases in the literature. We report a patient who experienced severe right shoulder discomfort three weeks prior to hospital admission which evolved to include both shoulders. Two weeks prior to admission he noticed the onset of discomfort in breathing in the supine position and shortness of breath with minor exertion. The admitting diagnoses were myocardial infarction due to significant ECG changes and idiopathic elevated bilateral hemidiaphragms. The patient had findings significant for tachypnea, dyspnea, decreased breath sounds at the bases bilaterally, impaired motion of the bilateral lung bases on inspiration and paradoxical respirations. Comprehensive medical testing and evaluation revealed bilateral elevated hemidiaphragms and vital capacity 40% of normal. Weakness of the proximal shoulder girdle and bicep musculature bilaterally was noted. Electromyography was significant for reduced recruitment pattern in the bilateral shoulder girdle musculature. Nerve conduction studies suggested bilateral phrenic neuropathy. This case is an unusual presentation of brachial neuritis affecting the bilateral shoulder girdle with phrenic nerve involvement. The differential diagnosis of acute shoulder pain associated with respiratory symptomatology should therefore include brachial neuritis.

During the 1995 outbreak of Ebola hemorrhagic fever in the Democratic Republic of the Congo, a series of 103 cases (one-third of the total number of cases) had clinical symptoms and signs accurately recorded by medical workers, mainly in the setting of the urban hospital in Kikwit. Clinical diagnosis was confirmed retrospectively in cases for which serum samples were available (n = 63, 61% of the cases). The disease began unspecifically with fever, asthenia, diarrhea, headaches, myalgia, arthralgia, vomiting, and abdominal pain. Early inconsistent signs and symptoms included conjunctival injection, sore throat, and rash. Overall, bleeding signs were observed in <45% of the cases. Typically, terminally ill patients presented with obtundation, anuria, shock, tachypnea, and normothermia. Late manifestations, most frequently arthralgia and ocular diseases, occurred in convalescent patients. This series is the most extensive number of cases of Ebola hemorrhagic fever observed during an outbreak.

Nucleoside reverse-transcriptase inhibitors (NRTIs) have been associated with functional and structural mitochondrial abnormalities, leading to several adverse events, such as increased serum lactic acid levels and lactic acidosis. Mild-to-moderate, asymptomatic hyperlactataemia has been frequently reported in human immunodeficiency virus (HIV)-infected patients treated with NRTIs, with an estimated prevalence between 15% and 35%. On the contrary, symptomatic, severe hyperlactataemia and lactic acidosis are less common, with an incidence ranging from 1.7 to 25.2 cases per 1000 person-years of antiretroviral treatment, and are associated with a remarkable mortality rate, which varies from 30% to 60% in different studies. The clinical presentation of lactic acid syndrome is non-specific and includes asthenia, malaise, nausea, vomiting, abdominal pain, weight loss, tachypnoea, dyspnoea, liver steatosis and increased transaminase levels, and risk factors include previous or concurrent therapy with stavudine or didanosine. Management of symptomatic lactic acid alterations involves NRTI-therapy interruption and supportive care, while natural history of hyperlactataemia is still unknown, and it is uncertain whether asymptomatic patients with increased lactate concentrations are at increased risk of developing lactic acidosis.
