Sarcoidosis treatment suppresses the granulomatous process and its clinical, functional and radiographic consequences but it is not etiological. Only a minority of patients necessitate systemic therapy. This is definitely required in severe extra-respiratory sarcoidosis including cardiac, neurological, renal, ocular involvement not responding to topical therapy and malignant hypercalcemia. ⋯ One of the following sparing agents can be associated with steroids when the threshold level to control the disease is high: hydroxychloroquine, methotrexate or azathioprine. An alternative option to corticosteroids is proposed in case of contra-indication or cortico-resistant sarcoidosis; methotrexate is then the treatment of choice. Although other drugs are only occasionnally needed, the available therapeutical range is wide (thalidomide, infliximab, cyclophosphamide, leflunomide...).

Cushing's syndrome results from inappropriate exposure to excessive endogenous glucocorticoids. Untreated, it has an important morbidity and a significant mortality. The syndrome remains a challenge to diagnose and manage. Here, we propose algorithms for the diagnosis of Cushing's syndrome and its cause, and review pathogenesis, clinical features, and treatment.

Aspergillosis, due to moulds belonging to the genus Aspergillus, occurs in patients with residual lung cavities. The clinical manifestations are determined by the host immune response, ranging from a local inflammatory response to the systemic dissemination. ⋯ The chest X-ray reveals a round mass with a radio-lucent crescent of air. The antifungal treatments are successful.

Acute ingestion of acetaminophen can induce a dose-dependent hepatotoxicity and lead to death. The management of acute acetaminophen poisoning at the early stage is well codified. A reported amount of ingestion > 200 mg/kg in a child, > 150 mg/kg in an adult (125 mg/kg if risk factors are present) require hospitalisation. ⋯ NAC is indicated if the serum acetaminophen level drawn 4 hours after ingestion and plotted on the nomograme falls above the "200 mg/L-4 hours" line. Nomograme is not usable with repeated acute ingestion or repeated supratherapeutic doses; presence of risk factors (enzymatic induction, malnutrition, chronic alcoholism) must be taken into account ("100 mg/L - 4 hours" line). Outcome is favorable with respect to these conditions.
