Background: Congenital heart disease represents a common type of birth defects. Cardiac surgery required for correction of these congenital anomalies may result in multiple neurological complications during or after surgery either transient or permanent. Aim of the Work:To determine the frequency and the outcome of the short term neurological complications in children undergoing congenital heart disease surgery. Patients and Methods: An observational prospective study was conducted in the postoperative cardiac Pediatric Intensive Care Unit (PICU) in Cairo University Children Hospital. It included 105 patients from 1 month to 12 years who underwent surgery for correction of the congenital heart disease. Follow up of the patients who developed neurological complications for 3 months post discharge from PICU was done to assess the outcome. Results: 16 patients (15.2%) developed acute neurological complications. Seizures were in 11 patients, 3 of them had associated disturbed conscious level (DCL) and stroke. Delayed recovery of consciousness was found in 6 patients, 5 of them were associated with seizures. Intensive care unit acquired weakness (ICUAW) was reported in 5 patients. Five patients with seizures were discharged, 3 of them with regressive course post discharge where seizures were controlled on a single antiepileptic drug (AED) and the other 2 with progressive course that necessitated addition of another AED. Four patients with ICUAW had regressive course post discharge. Conclusion: Acute neurological complications post congenital heart diseases surgery are serious morbidities and are associated with high risk of mortality. Primary prevention of these complications by using neuroprotective measures and avoiding the development of shock, and infection beside reduction of hospital stay can be helpful in decreasing incidence of complications and improving outcome among those patients.

The subject of this research is based on a survey of Ottoman mosques by the author in Greece, where around seven types were used in the Mosque design; three of them were very common and were separated across Greece (the single-unit-the T-plan-the "Eywan" Mosque-the quatrefoil plan), while three layouts were considered uncommon types of Ottoman mosques in Greece (the courtyard-the octagonal-the multi-domed mosques). In addition, uncommon elements were used in some mosques, such as the pogada roof of Ali Paşa Hilmi in Rhodes Island. The research aims to study the unconventional plan layout typology of Ottoman mosques and identify the extent to which these layouts were connected with the known Ottoman architecture. By offering the common Ottoman styles in Greece in general, the author selects some examples of Mosques and analyzes their morphologies. As a result, the architectural typologies of the floor plan of historical mosques in Greece were identified. The study concluded several types of plans. The current paper revealed that the typology of plans in historical mosques in Greece related to the plan typology of Islamic known styles.
