Aims and Scope
Evaluation of Prognostic Factors Associated with Postoperative Complications Following Pulmonary Hydatid Cyst SurgeryMojtaba Ahmadinejad, Mozaffar Hashemi, Nasim Azizallahi
Hydatid cysts are one of the serious complications following echinococcus infection. The liver and the lungs are the most affected organs, respectively. The severity of the disease is associated with the increase in the number and the size of the cysts, cysts rupture, and systemic effects. The aim of this study is to evaluate prognostic factors that are associated with the increased incidence of postoperative complications following pulmonary hydatid cyst surgery.
Patients referred to Madani hospital from 2014-2018, presenting pulmonary hydatid cysts were included in this study. All the patients were evaluated based on the following parameters: age, gender, location and size of the cysts, rupture status of the cysts (intact or perforated), type of surgical intervention (capitonnage or segmentectomy) and Erythrocyte Sedimentation Rate (ESR). The factors were then compared with postoperative complications. Statistical analysis of the data obtained was conducted using R-software
Of 76 patients enrolled in our study, 52.63% were males and 47.36% were female. Air leak complication was reported in 13.15% of the patients and 3.94% of the patients were presented with pleural effusion. Postoperative complications were significantly associated with the perforated (ruptured) cysts p= 0.001, segmentectomy p= 0.013, giant hydatid cysts p= 0.007 and ESR p= 0.014. However, the side of the lung was not significantly related to postoperative complications.
Our study reports that perforated cysts, increased size, segmentectomy and abnormal ESR are likely to increase postoperative complications following pulmonary hydatid cysts surgery. Prospective studies with perioperative parameters and greater sample size can help to deduce better inferences.

Evaluation of Breath-Holding Test in Assessment of Peripheral Chemoreflex Sensitivity in Patients with Chronic Heart FailureNikita Trembach, Igor Zabolotskikh
The sensitivity of peripheral chemoreflex is a marker of the severity of heart failure and the prognosis of the outcome in these patients. The assessment of chemosensitivity in these patients remains an actual problem.
The aim of the study was to explore the relationship between a Breath-Holding Test (BHT) and single-breath carbon dioxide test and to evaluate the reliability of both tests in patients with Heart Failure (HF).
The study was performed in 43 patients with chronic heart failure. All subjects underwent BHT and single-breath carbon dioxide (CB-CO2), the evaluation of both tests was repeated a month later. Relationship of two test was evaluated by correlation analysis. Reliability was assessed with calculation of Standard Error of Measurement (SEM), Coefficient of Variation (CV) and Intraclass Correlation Coefficient (ICC).
The duration of the breath-holding was inversely correlated to the result of CB-CO2 test (r = -0.86 at first measurement and r = -0.79 after a month) The ICC was 0.87 (95%CI: 0.78–0.93) for SB-CO2 test and 0,93 (95%CI: 0.88–0.96) for BHT, the CV was 24% for SB-CO2 and 13% for BHT. SEM for SB-CO2 test was 0.04 L / min / mmHg and limits of variation was 0.11 L / min / mmHg; SEM for BHT was 3.6 sec and limits of variation was10 sec.
Breath-holding test is a reliable and safe method for assessing the sensitivity of peripheral chemoreflex to carbon dioxide in patients with heart failure.
