Introduction: The COVID19 pandemic had a strong impact on the healthcare system, particularly in oncology. Brain tumor are usually revealed by acute and life threatening symptoms. We wanted to evaluate the possible consequences of the COVID19 pandemic in 2020 on the activity of neuro-oncology multidisciplinary tumor board in a Normandy region (France)., Methods: A descriptive, retrospective, multicenter study was conducted in the four referent centers (two universitary hospitals and two cancer centers). The main objective was to compare the average number of neuro-oncology patients presented per multidisciplinary tumor board per week between a pre-COVID19 reference period (period 1 from December 2018 to December 2019) and the pre-vaccination period (period 2 from December 2019 to November 2020)., Results: Across Normandy, 1540 cases were presented in neuro-oncology multidisciplinary tumor board in 2019 and 2020. No difference was observed between period 1 and 2: respectively 9.8 per week versus 10.7, P=0.36. The number of cases per week also did not significantly differ during the lockdown periods: 9.1/week versus 10.4 during the non-lockdown periods, P=0.26. The only difference observed was a higher proportion of tumor resection during the lockdown periods: 81.4% (n=79/174) versus 64.5% (n=408/1366), P=0.001., Conclusion: The pre-vaccination era of the COVID19 pandemic did not impact the activity of neuro-oncology multidisciplinary tumor board in the Normandy region. The possible consequences in terms of public health (excess mortality) due to this tumor location should now be investigated., (Copyright © 2023 Elsevier Masson SAS. All rights reserved.)

Multiple myeloma is a malignant proliferation of plasma cells, mainly affecting the bone marrow. It rarely occurs in young patients. The medical observation study reveals multiple myeloma discovered through a purulent pleurisy in a 28-year-old subject. This patient was admitted to the pneumology service of the Mohamed V military hospital in Rabat for a fever and dyspnea evolving into a context of poor general condition. Clinical examination found a right pleural fluid effusion syndrome. The pleural puncture reveals a germ-free exudative purulent fluid without plasma cells. The myeloma diagnosis was suspected due to the combination of an aplastic normochromic normocytic anemia at 4.5g/dL of hemoglobin, an accelerated erythrocyte sedimentation rate, hypercalcemia, renal failure and osteolytic lesions located mainly in the skull and pelvis area, oriented by electrophoresis and serum protein immunosubstraction revealing a narrow peak in monoclonal beta-2 globulin at 70.56g/L with a lambda monoclonal gammopathy with immunoglobulin G, and confirmed by the myelogram showing a 74% rate of bone marrow plasma cells. The occurrence of myeloma at a young age is rare and the purulent pleurisy without plasma cells is a rare form of presentation and represents a poor prognosis., (Copyright © 2015 Elsevier Masson SAS.

Introduction: Primary bronchial cancer (PBC) is a major public health problem. The diagnosis is often late resulting in a poor prognosis., Purpose: To determine the factors leading to a late diagnosis., Patients and Methods: All PBCs diagnosed between 01 January and 31 December were included. The factors studied were: "age, sex, smoking, place of residence, socioeconomic level, clinical signs, diagnostic means, histological types, the stages and date of treatment". The date of the first symptom (D1s), the date of care (Dpch), the date of the diagnosis (Ddg) and the date of the beginning of treatment (Dttt) were used to determine the delay before care., Results: One hundred and three cases of PBC were included. The medium delay before hospitalisation (D1s to Dpch) was 76 days, the delay before the diagnosis (Dpch to Ddg) was 25 days, the time before treatment (Ddg to Dttt) was 27 days, the time between hospitalisation and treatment (Dpch to Dttt) was 69 days, the overall delay (D1s to Dttt) was 160 days. The time before the diagnosis was longer in cases with a low socioeconomic level (30 days vs. 21 days, p: 0.06). The time before treatment was shorter for small cell carcinomas (SCC) (23 days vs. 31 days: p: 0.06). The time between hospitalisation and treatment was shorter for stages IIIB and IV of NSCBC (60 days vs. 67 days, p: 0.03). The overall delay was shorter for SCC (152 days vs. 168 days, p: 0.001)., Conclusion: The study confirms the problem of a delay in diagnosis. The effect of these delays on the prognosis has not been demonstrated and requires further study., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

Introduction: Neurological manifestations of celiac disease are rare and polymorphic. Similar to lesions of the digestive tract, the standard treatment includes steroids., Case Report: A 41-year-old woman, followed up for celiac disease resistant to gluten-free diet, developed rapidly spastic paraparesis, cerebellar syndrome, horizontal diplopia and decline of visual acuity. The diagnosis of neurological complications of celiac disease was established and the patient was treated with methylprednisolone, followed by oral prednisone. For 9 years, the patient's neurological status remained stabilized with a prednisone dose at 20mg per day. The patient relapsed when progressive reduction of prednisone dose was attempted; neurological and gastrointestinal signs worsening at 15mg per day; increasing the dose to 30mg improved the clinical status., Discussion: The mechanism of onset of neurological disease remains unknown. Immunological, nutritional, toxic or metabolic factors could be involved. The positive response to corticosteroids observed in this patient suggest an immunological mechanism.

Introduction: Calmette-Guérin bacillus (BCG) is a live attenuated strain used in tuberculosis vaccination. Local and systemic side-effects, although rare, are associated with BCG vaccine. They are common in cases of overdose and with poor vaccination techniques. These complications also occur in some cases of revaccination., Patients and Methods: This was a retrospective study over a period of 5 years between January 2000 and March 2005. 12 patients presenting complications following revaccination with BCG were observed. Patients were revaccinated with BCG following a negative intradermal reaction test. The following parameters were recorded: age, gender, history, vaccination method, type of complication, treatment and outcome., Results: There were 10 men and 2 and women of mean age 21 years (19 to 23 years). Mean time to consultation was 4 weeks. Complications comprised subcutaneous abscess in 8 cases, deep chronic ulcers in 4 cases complicated by humeral osteitis in one case. The dose administered was 0.1 ml in 9 patients and 1 ml in 3 others (i.e. 10 times the recommended dose). Six patients had extensive and progressive ulceration, with one positive culture, the presence of a granuloma with caseum necrosis and one case of humeral osteitis, and specific treatment was given., Discussion: Revaccination is no longer recommended by the WHO since efficacy is considered to be low or even nil. Intradermal injection is the reference method for BCG vaccination. Technical errors such as injection of an excessively high dose of the vaccine or subcutaneous administration of the vaccine solution increase the incidence of adverse effects. In our study, three patients erroneously received 1 ml of vaccine and the injection was too deep in 9 cases. There are few reports in the literature concerning the underlying mechanisms of these post-revaccination accidents; two major physiopathological mechanisms, infectious and immunological, are discussed. There is no consensus regarding treatment of these complications. Six of the 12 patients received specific therapy for 6 months.

Behcet syndrome is a systemic disease with venous tropism, generally expressed by thrombosis and phlebitis. Arterial involvement is more exceptional but can lead to aneurysm of the pulmonary artery, generally not more than three. We report a patient with Behcet syndrome who developed multiple aneurysms of the pulmonary artery and discuss the clinical, radiological aspects as well as the disease course and therapeutic management.

We report a case of a patient with intrathoracic extramedullary hematopoiesis presenting as a posterior mediastinal tumor, without associated myelofibrosis. Pathophysiology and the options for diagnosis and treatment in this condition are discussed.

Leptospirosis is a systemic infection transmitted to man by a variety of animals. Classical manifestations include fever, liver and renal involvement, meningoencephalitis and hemorrhage. Pulmonary involvement is less common, generally expressed by hemoptysis and bilateral reticulonodular infiltration on the chest x-ray. Pulmonary disease is one of the principal causes of mortality. We report the cases of two patients aged 22 and 32 years who were hospitalized for moderately abundant hemopysis and fever. The diagnosis of leptospirosis with pulmonary involvement, strongly suggested by the classical extrapulmonary signs and was confirmed later. The patients were given antibiotics (amoxicillin, cycline). Clinical, biological and radiological outcome was favorable.

We report a case of primary pulmonary Hodgkin's disease in a 20 year-old woman. The chest x-ray showed a chronic alveolar syndrome. The diagnosis was established from a pulmonary biopsy. The radiological features and the options for diagnosis of primary pulmonary Hodgkin's disease are discussed.
