Previous studies have reported conflicting survival rates for connective tissue disease (CTD)-associated usual interstitial pneumonia (UIP) and idiopathic pulmonary fibrosis (IPF/UIP). This study investigated the differences in the clinical characteristics and prognoses of patients diagnosed with CTD-UIP and IPF/UIP. ⋯ Our findings indicate that the survival of CTD-UIP patients was similar compared with that of IPF/UIP patients. However, it appears that UCTD influences the survival rate of CTD-UIP patients.

Double lung point is a rare sign of pneumothorax in clinical practice. In this report I presented an 18-month-old child who presented with bilateral pneumothorax. ⋯ To the best of our knowledge, this is the first case of double lung point identified with ultrasonography in child. The strength of the case is that the double lung point sign is supported by computed tomography (CT). Furthermore, we propose that the presence of double lung point indicates limited pneumothorax and conservative management may well be attempted.

Prone positioning for acute respiratory distress syndrome (ARDS) has no impact on mortality despite significant improvements in oxygenation. However, a recent trial demonstrated reduced mortality rates in the prone position for severe ARDS. We evaluated effects of prone position duration and protective lung strategies on mortality rates in ARDS. ⋯ Prone positioning tends to reduce the mortality rates in ARDS patients, especially when used in conjunction with a lung protective strategy and longer prone position durations. Prone positioning for ARDS patients should be prioritized over other invasive procedures because related life-threatening complications are rare. However, further additional randomized controlled design to study are required for confirm benefit of prone position in ARDS.

We present an extremely rare case of a giant pulmonary hamartoma (PH) coexisting with an anomalous common pulmonary venous trunk (ACPVT). An asymptomatic 39-year-old man was referred for evaluation of a giant pulmonary lesion in his left thorax detected on chest X-ray during a routine medical examination. After clinical work-up, the patient underwent left exploratory thoracotomy. ⋯ Histology revealed a blend of pieces of rounded cartilage separated by fibrous bands in which mature adipose tissue and cleft-like structures lined. The features were consistent with those of a chondromatous hamartoma. The patient made a satisfactory recovery and 10 months after the operation was asymptomatic.
