“…In our study, more than half of the cases involved perforated cysts (50.4%). A very similar frequency (53.1%) was seen in a study conducted by Ashour et al [9], but a lower rate (41%) was observed in children under 16 years old in a study conducted by Onal and Demir [10]. The male-to-female ratio in the present study was 1:1.5 for group 1 and 1:1.7 for group 2, while it was 2:1 in both groups in the study by Ashour et al [9].…”

Background: Hydatidosis is a major health problem around the world, especially in the Mediterranean region. Cysts can break open or develop secondary bacterial infections, alter ing the clinical presentation. Methods: Patients who underwent hydatid cyst surgery at AlMouassat University Hos pital in Damascus, Syria between January 2006 and December 2017 were evaluated. Cases involving isolated hepatic cysts were excluded. The patients were divided into those with perforated hydatid cysts (group 1) and those with intact hydatid cysts (group 2). Results: This study included 224 cases: 113 in group 1 (50.4%) and 111 in group 2 (49.6%). The median chest tube duration, hospitalization time, and postoperative complication rate were higher in group 1 than in group 2 (p=0.003, p=0.002, and p=0.006, respectively). In both groups, the most common symptom was cough (present in 178 patients in total [79.5%]), while chest pain (121 patients [54%]) and dyspnea (113 patients [50.4%]) were also common. Cough, hemoptysis, fever, and expectoration of cystic contents were signifi cantly more frequent in group 1 than in group 2 (p<0.001). Conclusion: The early discovery and treatment of intact pulmonary hydatid cysts re duced the hospitalization time, chest tube duration, and postoperative complication rate. Relative to intact cysts, perforated cysts are more complex and are associated with more expensive and timeconsuming surgical treatment.

“…This increased tension on the wall of a cyst, resulting in its rupture, has been proven elsewhere as a cause of rupture of pulmonary hydatid cyst. 17 In a retrospective study conducted in China on 337 patients with PSP, a strong correlation was found between the occurrence of PSP and fall in the mean atmospheric pressure. The mean atmospheric pressure in PSP days was obviously lower than that of non-PSP days.…”

Introduction Although links between meteorological conditions and primary spontaneous pneumothorax have been proposed, the reports are controversial. The aim of the study is to correlate between climatic changes and the development of this condition. Materials and methods A retrospective chart review included all patient presenting with primary spontaneous pneumothorax to King Fahd Hospital, Imam Abdulrahman Bin Faisal University, Alkhobar, Saudi Arabia, from 1 January 2005 to 31 December 2016. Meteorological data were collected from King Abdulaziz airbase station using an online source for the same time interval. The data were analysed to determine differences in weather conditions between days on which primary spontaneous pneumothorax occurred and those in which it did not. Logistic regression model was used to obtain predicted risks for the onset of primary spontaneous pneumothorax with respect to weather conditions. Result Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without. Conclusion Two hundred and eighty-nine patients were found to have primary spontaneous pneumothorax in the 281 days included in the study. Among the meteorological parameters, significant differences were found in average temperature and atmospheric pressure difference between day of admission and two days before the admission, between days with primary spontaneous pneumothorax and days without. There was no significant difference in the other meteorological factors between days with primary spontaneous pneumothorax and days without.

“…Clinical presentation depends on whether the cyst is intact or ruptured [4,11]. Rupture of the cyst into bronchus causes hemoptysis or expectoration of the cystic content [12][13][14][15]. Purulent sputum with fever might occur in cases with infected cyst.…”

“…In addition to these, sometimes life-threatening complications might arise following the rupture of HC. Rupture of cyst may lead to asphyxia due to flooding of bronchial tree with hydatid fluid or blockage of bronchial lumen due to germinal membrane [12]. We had two cases where emergency intervention and surgery were needed.…”
