The risk of recurrence of Pilonidal disease after surgical management

Background: The prevalence of primary spontaneous pneumothorax is high in the Arab region. There is a lack of studies from the Eastern Province of Saudi Arabia highlighting the associated risk factors and demonstrating the effectiveness of surgical management. Objectives: To identify risk factors associated with primary spontaneous pneumothorax and to correlate the effectiveness of surgical management with the rate of disease recurrence. Subjects and Methods: This retrospective chart review included adult patients who presented with primary spontaneous pneumothorax and were managed at King Fahd Hospital of the University, Al-Khobar, Saudi Arabia, from January 1, 2005, to December 31, 2014. The results are presented as arithmetic mean for quantitative data, and chi-square test was used for statistical analysis. P ≤0.05 was considered statistically significant. Results: In total, 151 patients with primary spontaneous pneumothorax were included, with the majority being male (98.7%) and Saudis (88.7%). The mean age was 24 ± 6 years (range: 13–49 years), mean height 171 ± 8 cm (range: 144–193 cm) and mean body mass index 19.2 ± 3.8 kg/m² (range: 13.3–39.0 kg/m²). About 62% of the patients were smokers. Ten patients had an ipsilateral recurrence of primary spontaneous pneumothorax after the first episode was successfully managed. Surgical exploration after the first episode itself was found to significantly reduce the recurrence rate. The study found that in the management of these patients, there was a shift from conventional open thoracotomy to the minimally invasive video-assisted thoracoscopic surgery method. Conclusions: The risk factors for primary spontaneous pneumothorax in this study were consistent with the current literature. Surgical exploration after the first episode of primary spontaneous pneumothorax significantly reduces the recurrence rate and there is a paradigm shift toward a less invasive surgical approach in managing these patients.

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.

Background/Objectives: Hypoparathyroidism (HPT) is a common complication following thyroid surgery with an incidence reaching up to 29%, potentially resulting in significant long-term morbidity. To improve its early identification and patient outcomes, we investigated the prevalence and predictors of postoperative HPT. Methods: This retrospective, multicenter observational study included patients who underwent thyroid surgery from 2016 to 2022 in four centers located in Saudi Arabia’s Eastern Province. We analyzed demographic data, underlying thyroid or parathyroid conditions, surgical indications, types of procedures, pathology results, and preoperative corrected calcium and vitamin D levels, along with postoperative corrected calcium and parathyroid hormone (PTH) levels. For data analysis, IBM Statistical Package for the Social Sciences (SPSS) Statistics 22 was used, with categorical variables presented as frequencies/percentages and non-normal continuous variables as the median/first quartile (Q1) and third quartile (Q3). Associations were tested with chi-square/Fisher exact tests, medians with Mann–Whitney U-tests, and odds ratios (ORs) with 95% confidence intervals (CIs) via multivariate analysis with statistical significance set at p < 0.05. Results: A total of 679 cases were included. The median age of patients was 43 years (with 48.9% of them aged 41–60 years), and 82% were female. HPT occurred in 228 cases (35.3%), with 115 (81.0%) experiencing transient HPT and 27 (19.0%) permanent HPT. Multivariate analysis identified total thyroidectomy (OR 2.7, p = 0.005), completion thyroidectomy (OR 8.4, p = 0.004), and low immediate postoperative PTH level (OR 3.1, p < 0.001) as independent predictors of HPT. Central lymph node dissection (CLND; OR 4.03, p = 0.004) and low postoperative PTH level (OR 2.56, p = 0.049) were significant predictors of permanent HPT. Conclusions: Key predictors of HPT include surgical extent and low postoperative PTH level, while CLND and low postoperative PTH level are the strongest predictors of permanent HPT. Careful assessment of these risks when determining the extent of surgery and avoiding unnecessary aggressive procedures can help to minimize the occurrence of HPT. Measuring the PTH level immediately after surgery may aid in identifying high-risk patients for early intervention and appropriate follow-up.
