Simultaneous bilateral spontaneous pneumothorax as the first manifestation of primary pulmonary MALT lymphoma.

Primary pulmonary lymphoma is a rare entity. Furthermore, simultaneous bilateral spontaneous pneumothorax (SBSP) is a very rare condition which is often related to therapeutic complications. We present, to the best of our knowledge, the first case of primary pulmonary mucosa associated lymphoid tissue (MALT) lymphoma revealed by SBSP. A 50-year-old female was diagnosed with organizing pneumonia. One month later, she presented with sudden chest pain and shortness of breath due to SBSP. Bilateral chest tubes were inserted. A scan- guided right lung biopsy led to the diagnosis of primary pulmonary MALT lymphoma. The patient was treated with R-CHOP chemotherapy. The association between lymphoma and pneumothorax is extremely rare, often related to therapeutic toxicity. We report the case of SBSP as the first manifestation of primary pulmonary MALT lymphoma.

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.

Choroidal metastasis as the initial presentation of lung adenocarcinoma: A case report.

Clinical reports of symptomatic choroidal metastasis as the initial presentation of lung cancer are rare. Here, we report such a presentation in a female patient of non small cell lung cancer. She presented with loss of vision in her left eye. On further analyses, the patient was diagnosed with a lung adenocarcinoma.

[Clinical course of the ventilatory function in COPD: analytical study of 160 cases]. / Evolution de la fonction ventilatoire chez les BPCO. Etude analytique de 160 cas.

The incidence of chronic obstructive pulmonary disease (COPD) is increasing particularly in developing countries. Their prognosis depend on several factors in particular the one second forced expiratory volume (FEV1) decline. To study FEV1 decline speed and factors affecting it, we carried out a retrospective study of 160 cases of COPD in stable state and heaving at least two FEV1 measures at 6 months of interval in the minimum and. The middle age was 63 +/- 12 yr, 52% was former smokers and 46% current smokers, with middle of 50 +/- 27 pack-yr. The FEV1 decline was calculated by linear regression models. The decline average in FEV1 with time was 72 +/- 55 ml/yr. Absolute value was higher than 30 ml/yr therefore more accelerated than general population in 79% of cases. We confirmed by multivariate analysis that age and smoking habit and increased the FEV1 decline. However this last correlated with FEV1% predicted. We concluded that the decline of FEV1 is higher in COPD that in the general population and slowing it needs smoking stop.

[Thyroid assessment in suspected sleep apnea syndrome]. / Le bilan thyroidien au cours des suspicions de syndrome d'apnées du sommeil.

The sleep apnea syndrome (SAS) and hypothyroidism have several common signs. This similarity creates a significant risk of undiagnosed hypothyroidism during the SAS. We studied the interest of thyroid function testing at patients suspected of having SAS. 201 consecutive patients, having a suspicion of SAS without history of hypothyroidism, underwent polysomnography (PSG) and biochemical thyroid testing. 91 patients (47%) had a SAS. Three patients among them (1.5% of patients undergoing PSG or 3.3% of those having a SAS) had previously undiagnosed hypothyroidism. These three patients have been treated by thyroxine. After euthyroidism was obtained by the treatment, SAS disappeared in 2 patients. The prevalence of the hypothyroidism in patients suspected of having SAS is not different from the one in the general population. However it is greater in patients with SAS. So we can conclude that biochemical screening for hypothyroidism is indicated only in case of proven SAS, in order to distinguish between a primary and a secondary origin.

[Obstructive sleep apnea syndrome. Analytical study of 63 cases]. / Syndrome d'apnees obstructives du sommeil (SAOS). Etude analytique de 63 cas.

Obstructive sleep apnoea (OSA) is a relatively common disorder, in developed country with prevalence estimated to lie between 2 and 4% in adult population. The diagnosis of this syndrome is made on the basis of characteristic clinical features and the results of nocturnal polysomnography. There is no data concerning the OSA in developing country. It is therefore of interest to determine the clinic and polysomnographic profile of this disease and to landmark factors correlated with severity in our country. This was achieved by studying a set of 63 OSA. The mean of age was 53 + 13 years with sex ratio 1. The means of Epworth sleepiness scale score, BMI and Apnoea/Hypopnoea index (AHI) were respectively 16 + 4, 38.8 + 7 kg/m2 and 51.7 + 28.6. 44% of patients have OSA severe with IAH > 50/h. Arousal index and desaturation index were respectively 36.4 + 21.7 and 49 + 26. Trial of continuous positive airway pressure (CPAP) therapy was proposed first to 40 patients, 17 were able to use CPAP.

[Embolic pseudotumor diagnosed by surgery]. / Nodule pulmonaire pseudotumoral d'origine embolique de decouverte chirurgicale.

We report a case of pulmonary infarction in a 72-year-old woman who was hospitalised for hemoptysis, chest pain and weight and coin a lesion in the loss periphery of the left lower lobe. Camputed tomography of the chest demonstrated a sub pleural solitary nodule with spicular radiation. Video-assisted thoracoscopic surgery was performed to obtain a histological diagnosis. Thoracoscopic examination showed a lesion that evoked chronic abscess. Histological examination confirmed an ischemic infarction. This is the second case of pseudotumor due to pulmonary infarction that was diagnosed by video-assisted thoracoscopic resection.
