Molar-incisor hypomineralization (MIH), a developmental enamel defect affecting one or more first permanent molars (FPMs) and sometimes incisors (PIs), is one of the most common pandemic health problems in the world. MIH etiology is still unclear and has been suggested to be related to exposure to environmental toxicants during enamel mineralization. ⋯ MIH prevalence among children born around 2006 Lebanese war is high. The hypothesis of a relation between MIH susceptibility and war pollutants in bombarded regions is legible but requires to be elucidated via additional in vitro and in vivo studies for accurate risk assessment.

Uncorrected refractive error has profound effects on children's educational and social development and spectacles are cost-effective in correcting this. However, the cosmetic appearance of spectacles may affect compliance to prescribed spectacles. ⋯ Spectacle preferences exist among the study population and some demographic factors are associated with these preferences which should be considered in any childhood refractive error services.

Case Reports
Mechanic ileus due to retroperitoneal migration of total hip prosthesis; A case report.
Intrapelvic migration of total hip prosthesis is a rare but severe complication of total hip arthroplasty that can cause severe outcomes for elderly patients. A 78-year-old female patient was referred to our hospital with the complaint of no gas-stool excretion for 3-4 days, abdominal distension, nausea, vomiting, and a preliminary diagnosis of ileus. Computed tomography showed the migration of the left total hip prosthesis to the pelvis, causing a hematoma around the prosthesis and mechanical ileus due to the compression of the hematoma. ⋯ Although postop paralytic ileus is one of the complications of total hip arthroplasty, mechanical ileus has not been described before. This case report shows that mechanical ileus might be an unreported complication of total hip arthroplasty. It should be kept in mind that mechanical ileus complications may also occur after hip arthroplasty.

Recent reports have shown that left-and right-sided colon cancers display different clinical and biological features. Chromosomal instability, epigenetic alterations, and defects in the deoxyribonucleic acid (DNA) mismatch repair (MMR) system may lead to the development of colorectal cancer (CRC). Besides microsatellite instability (MSI) caused by DNA MMR activity degradation increases the risk for CRC. ⋯ Although it was not statistically significant, tumors with MMR deficiency (dMMR) and high microsatellite instability (MSI-H) are more common in right-sided colon tumors.

This study aims to investigate the potential application of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict concurrent chemoradiation (CRT) in locally advanced esophageal carcinoma. ⋯ Pre-Ktrans could be a promising parameter to forecast how patients with locally advanced esophageal cancer will respond to CRT.
