Background: Primary spontaneous pneumothorax (PSP) tends to occur in young adults without underlying lung diseases and is usually followed by limited symptoms, while secondary spontaneous pneumothorax (SSP) is a complication of a pre-existing lung disease. Surprisingly, for such common conditions, there is a considerable inconsistency regarding management guidelines.

Objectives: To evaluate the risk factors for spontaneous pneumothoraxes and to summarize outcomes and complications based on our clinical experience.

Methods: This retrospective study group was comprised of 250 consecutive patients older than 18 years of age who were diagnosed with spontaneous pneumothorax and hospitalized at the Meir Medical Center (2004–2017). Data on demographic characteristics, indicating symptoms, chest X-rays, and chest computed tomography (CT) results were collected. Our experience and outcomes were then compared to a large multicenter study.

Results: Most of the patients were male (85%) and past or current smokers; 69% presented with PSP, while the rest were SSP. No occupational relation was noted. About 55% of the cases presented with a moderate or large pneumothorax (over 1/3 hemithorax). Most patients (56%) required chest tube drainage and 20% undergone surgery. Nearly 10% presented with a recurrent pneumothorax with the mean time to recurrence being 11 ± 20 days. Although the length of hospital stay of patients that underwent surgery was the longest (P < 0.001) for both PSP and SSP, the recurrence rate was actually reduced, suggesting some benefit for the surgical treatment option.

Conclusions: Our experience showed that the traditional approach to the PSP treatment should be further considered, as previously suggested.

Background: Patients with severe chronic obstructive pulmonary disease (COPD) experience frequent exacerbations and need to be hospitalized, resulting in an economic and social burden. Although data exist regarding reasons of frequent hospitalizations, there is no data available about the impact on the length of stay (LOS).

Objectives: To characterize the causes of prolonged hospitalizations in COPD patients.

Methods: A retrospective study was conducted of patients who were diagnosed and treated in the pulmonary department for severe COPD exacerbations. All patient demographic data and medical history were collected. Data regarding the disease severity were also collected (including Global Initiative for Obstructive Lung Disease [GOLD] criteria, pulmonologist follow-up, prior hospitalizations, and LOS).

Results: The study comprised 200 patients, average age 69.5 ± 10.8 years, 61% males. Of these patients, 89 (45%) were hospitalized for up to 4 days, 111 (55%) for 5 days or more, and 34 (17%) for more than 7 days. Single patients had longer LOS compared with married patients (48% vs. 34%, P = 0.044). Multivariate analysis showed that the number of prior hospital admissions in the last year was a predictor of LOS (P = 0.038, odds ratio [OR] = 0.807, 95% confidence interval [95%CI] = 0.659–0.988), as well as the use of non-invasive respiratory support by bilevel positive airway pressure (BiPAP) during the hospitalization (P = 0.024, OR = 4.662, 95%CI = 1.229–17.681).

Conclusions: Fewer previous hospitalizations due to COPD exacerbations and the need for non-invasive respiratory support by BiPAP were found as predictors of longer LOS.

Background: Pulmonary embolism (PE) is the third most frequently occurring cardiovascular disease. However, the clinical presentation in patients with PE is variable.

Objectives: To evaluate the prevalence of radiological findings detected in contrast-enhanced computed tomography angiography (CTA) and their significance in patients with PE; and to assess whether the CTA findings differed in patients receiving tissue plasminogen activator (tPA) therapy from those who did not.

Methods: We retrospectively reviewed CTA scans of 186 patients diagnosed with acute PE. Incidental findings on CTA scan were assessed, including mediastinal and parenchymal lymph nodes, pleural effusion, space-occupying lesions, consolidations, emphysema, and pericardial effusion.

Results: Patients receiving tPA (19.9%) were less likely to have pleural effusion (29.7% vs. 50.3%, P = 0.024). Other CTA findings did not differ between the tPA and non-tPA groups, including lung infiltrates (40.5% vs. 38.9, P = 0.857), space-occupying lesions (5.4% vs. 6.7%, P = 1), pericardial effusion (8.1% vs. 8.7%, P = 1), emphysema (21.6% vs. 17.4%, P = 0.557), lung (18.9% vs. 24.2%, P = 0.498), and mediastinal ( 24.3% vs. 25.5%, P = 0.883) lymph nodes, respectively.

Conclusion: The prevalence of pleural effusion (unilateral or bilateral) was higher in patients not treated with tPA. Therefore, in patients with a borderline condition, the presence of pleural effusion could support the decision not to give tPA treatment.

Background: Obstruction of urine outflow can result from mechanical blockade as well as from functional defects. In adults, urinary tract obstruction is due mainly to acquired defects, such as pelvic tumors, calculi, and urethral stricture. In childhood it is mostly due to congenital malformations. In this article we present two rare cases of acute obstructive renal failure that presented with hydronephrosis. These cases underline the wide range of causes that may lead to this clinical feature.
