Miliary tuberculosis following intravesical Bacillus Calmette and Guérin therapy: A rare complication of a frequent procedure.

The standard treatment for superficial vesical tumors is transurethral resection (TUR) followed by intravesical instillation of Bacillus Calmette and Guérin (BCG). Pulmonary complications of BCG-therapy are rare but could be life threatening. We report the case of a 54-year-old patient who received BCG-therapy after TUR. After the sixth session of BCG instillations, the patient was diagnosed with a miliary tuberculosis secondary to BCG-therapy. We observed a progressive clinical and radiological improvement under specific tuberculosis treatment. Early diagnosis of pulmonary side effects of BCG-therapy and prompt treatment are the keys to complete recovery and survival.

Bilateral pleural metastases of a primary central nervous system neuroblastoma in an adult: First case in the world.

Primary central nervous system neuroblastoma (PCNS-NBL) is a rare and aggressive malignant tumour. Pleural metastases of PCNS-NBL have not been documented before. We report a case of a 30-year-old male patient, with a history of PCNS-NBL treated with surgery, radiation and chemotherapy. Three years later, he presented an aggravated dyspnoea with impaired general condition. The different investigations confirmed that his PCNS-NBL has relapsed with bone, lymph nodes and bilateral pleural metastases. Because of the disseminated disease and the poor general condition of the patient, only symptomatic treatment measures were preconized. The patient died 3 months later following cardiorespiratory arrest. To the best of our knowledge, this is the first case reporting bilateral pleural metastases of a PCNS-NBL in a young adult.

[Factors predicting the need for invasive mechanical ventilation in patients with chronic obstructive pulmonary disease (COPD)]. / Facteurs prédictifs de la ventilation mécanique invasive chez les patients atteints de broncho-pneumopathie chronique obstructive (BPCO).

INTRODUCTION: the use of invasive mechanical ventilation (IMV) in acute exacerbations of chronic obstructive pulmonary disease (AECOPD) constitutes a negative turning point in the progression of the disease. The purpose of this study is to determine factors predicting the need for IMV in AECOPD. METHODS: we conducted a retrospective study by reviewing the medical records of patients with AECOPD hospitalized in our Department over a 18-year period (2000-2017). We compared 2 groups: G1: patients with AECOPD undergoing at least one IMV and G2: patients who had never undergone IMV following AECOPD. RESULTS: the study included 1152 patients with COPD: 133 in the G1 group (11.5%), and 1019 in the G2 group (88.5%). G1 patients were more symptomatic (p < 0.001), with more severe bronchial obstruction (p < 0.001). G1 patients had more exacerbations (p < 0.001), more hospitalizations and a higher need for non-invasive ventilation (NIV) (p < 0.001). Similarly, G1 patients more often developed chronic respiratory failure (p < 0.001) and had significantly lower survival rates. Independent risk factors associated with IMV were hypercapnia and decreased pH (in patients with severe AECOPD), a history of NIV, and chronic respiratory failure (CRF). CONCLUSION: respiratory function impairment, the severity of exacerbation and the need for NIV in a previous episode are factors predicting the need for IMV and poor outcomes.

[Influence of co-morbidities on the progression and prognosis of patients with chronic obstructive pulmonary disease in a Tunisian Hospital]. / Influence des comorbidités sur l'évolution et le pronostic des patients porteurs de broncho-pneumopathie chronique obstructive dans un centre tunisien.

INTRODUCTION: chronic obstructive pulmonary disease (COPD) has been frequently associated with co-morbidities. The purpose of our study is to analyze the impact of co-morbidities on the progression and prognosis of COPD. METHODS: we conducted a retrospective study of patients with COPD hospitalized and/or followed up in the Department of Pneumology at the Fattouma Bourguiba University Hospital in Monastir over the period January 2000-December 2017. The patients were initially divided into two groups, the G0 group (isolated COPD) and the G1 group (with at least one comorbidity). Patients in the G1 group were divided in two subgroups: A group (patients with 1-2 co-morbidities) and B group (≥ 3 comorbidities associated). Different parameters of COPD severity were compared between the different groups. RESULTS: a total of 1152 patients with COPD were enrolled. Seventy-nine percent of patients had at least a chronic disease associated with COPD. The presence of at least one co-morbidity was associated with an increase in the number of severe exacerbations (p = 0.004), in the use of Long-term oxygen therapy (p = 0.006) and with reduced survival (p = 0.001). Similarly, a greater number of co-morbidities (≥ 3 co-morbidities) were associated with more severe systemic inflammation, more frequent use of mechanical ventilation or non-invasive ventilation (p=0.04) and reduced survival (p = 0.05). CONCLUSION: the presence of co-morbidities in patients with COPD is associated with higher severity and poorer prognosis.

Mounier-Kuhn syndrome: A variable course disease.

Mounier-Kuhn syndrome or tracheobronchomegaly is a rare disease characterized by marked dilation of the trachea and proximal bronchi with recurrent lower tract respiratory infections. Computed tomography and bronchoscopy are the key tools to accomplish the diagnosis. This is a condition with a clinical polymorphism, symptoms vary from minor with preserved respiratory function, to very severe with life threatening exacerbations leading to respiratory failure and premature death. The treatment is mainly symptomatic, stenting or surgery are reserved to extreme cases.Herein, we report two cases of the same condition with different clinical signs and diverse outcome.
