[Symptoms and natural history of hospital chronic obstructive pulmonary disease]. / Symptômes et histoire naturelle de la broncho-pneumopathie chronique obstructive en milieu hospitalier.

BACKGROUND: Since few years, the data describing the chronic obstructive pulmonary disease (COPD) have changed and new concepts have emerged. AIM: To study the clinical characteristics and outcome of patients with COPD in a Tunisian population. METHODS: It is a retrospective study including 150 patients with COPD admitted at the pulmonary department of Charles Nicolle Hospital in Tunis, during a period of ten years. RESULTS: Data from 150 patients hospitalized at the pulmonary department of Charles Nicolle Hospital in Tunis, were analyzed. They were 126 men and 24 women with a mean age of 67 years. Tobacco was the predominant risk factor. Eighty-two (55%) patients were classified GOLD stage IV at diagnosis. The number of exacerbation varied from 1 to 7 with an average higher in patients classified as stage IV (p = 0.007). CONCLUSION: The COPD is pathology of smoking men. Comorbidities and exacerbations prevalence increase according the disease severity. In fact, better knowledge of exacerbations etiologies allows considering better measurement of prevention.

Assessment of EGFR mutation status in Tunisian patients with pulmonary adenocarcinoma.

BACKGROUND: Despite recent advances, non-small cell lung cancer carries a grim prognosis. For appropriate treatment selection, the updated guidelines recommend broad molecular profiling for all patients with pulmonary adenocarcinoma. Precise histological subtyping and targeted epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) testing are mandatory. METHODS: Herein, we assessed the EGFR mutation status of 26 formalin fixed-paraffin embedded (FFPE) samples of lung adenocarcinoma. Mutational analysis concerned exons 18-21 of EGFR by real-time polymerase chain reaction (Real time-PCR) using the Therascreen EGFR RGQ PCR mutation kit. ALK status was established on 22 among 26 patients using D5F3 antibody with a fully automated Ventana CDx technique. RESULTS: Activating EGFR mutations were found in 3 men among 26 patients (11.5%). Positive ALK expression was found in 2 cases among 22 patients (9.09%). CONCLUSION: Frequency of EGFR mutations in pulmonary adenocarcinomas of our series is similar to that found in the European ones with some particularities. The mutations detected are uncommon. Whereas, we found a high frequency of positive ALK expression in our series compared to frequency reported in literature. Further studies with larger Tunisian series are required to obtain more conclusive results.

[Alveolar haemorrhage following a cannabis water pipe]. / Hémorragie alvéolaire suite à un bang de cannabis.

Respiratory toxicity of cannabis is well-known today particularly with the new consumption patterns. We report the case of a 25-year-old man admitted for haemoptysis, with unfavourable outcome and acute respiratory failure. Various explorations concluded to acute respiratory distress syndrome secondary to diffuse alveolar haemorrhage. Etiological assessment was initially negative. Outcome was favourable during hospitalization, authorizing the discharge of our patient. Two days later, alveolar haemorrhage recur, with positive toxicological tests for cannabis and the patient admits smoking cannabis by plastic "bang". We illustrate, through this case, the severity of respiratory complications caused by new methods of using cannabis, particularly with plastic 'bang', hence the need to insist of the importance of supported withdrawal and to inform young people how these techniques are serious.ssss.

Recurrent iliac hydatidosis: A case report.

INTRODUCTION: Hydatid cysts may occur in any area of the body, but they usually localize to the liver and the lungs. Primary localization in bone is not common. PRESENTATION OF CASE: The authors report the case of multifocal hydatid disease appeared 3 years after the surgical treatment of a cyst of the hip. The patient presented with cough and chest pain of 2 months duration. Only the lung localization was symptomatic. The thoracic echography, the abdominal and chest scan allowed the diagnosis. DISCUSSION: Hydatid recurrence remain frequent, whatever is the nature of the treatment, surgical or chemical. CONCLUSION: The premature detection of recurrence is of great importance.

[Bilateral pleural thickening]. / Épaississement pleural bilatéral de la plèvre.
