Variations in Epithelial Lining of Duplication Cysts Cannot be Explained by Known Theories.

Duplication cysts are found in any part of the gastrointestinal tract from the oropharynx to anus. Although duplication cysts usually have similar epithelium with the adjacent organ, respiratory epithelium in the enteric duplication cysts is rarely reported. This study was performed to evaluate the variations in the epithelial lining of duplication cysts and its clinical implications.

Magnet ingestion in growing children: a multi-center observational study on single and multiple magnet incidents.

Over the past 15 years, there has been a noticeable uptick in incidents involving children ingesting multiple magnetic foreign bodies which can cause injuries and gastrointestinal complications including death. The current study aimed to identify the prevalence, clinical presentation, and management of single or multiple magnet ingestions. A retrospective multi-central cross-sectional study was conducted to include all pediatric patients < 18 years presented to the emergency department with ingestion of single or multiple magnets and admitted across hospitals in Qatar, UAE, KSA, Tunisia, and Turkey between January 2011 and December 2021.

The miRNA-24, miRNA-21 expressions and matrix metalloproteinase-7 level in exhaled breath condensate of children with primary spontaneous pneumothorax.

Bullous lung diseases may cause primary spontaneous pneumothorax (PSP) in children. The microRNAs (miRNAs) are non-coding RNAs that participate in regulation of inflammation and cancer. We hypothesized that children with bullous lung disease and PSP may have altered miRNA expressions in their exhaled breath condensates (EBCs).

The results and outcome of primary spontaneous pneumothorax in adolescents.

Aim: Primary spontaneous pneumothorax (PSP) is a rare pulmonary pathology that occurs in the absence of known lung disease. A retrospective study was performed to evaluate the results and outcome of PSP treatment in adolescents.

Methods: The cases with PSP from January 2004 to December 2017 were evaluated for age, sex, family and smoking history, clinical and radiological findings and results of treatment.
