Objective: Traditionally vascular rings in infants and children are treated through an open thoracotomy. Recently, thoracoscopic surgery has been used for these complex procedures. This study reports our early experience with thoracoscopic division of vascular rings and evaluates the efficacy and safety of this approach.
Material And Methods: Patients who underwent thoracoscopic division of vascular rings at King Khalid University Hospital, Riyadh, Saudi Arabia, from December 2004 to January 2006 are included. Their data were carefully analyzed looking at demographics, clinical presentation, diagnostic modality, type of the anomaly, operative details, complications, and outcome.
Results: A total of 9 patients underwent thoracoscopic division of vascular rings. Age at surgery ranged between 2 and 108 months (mean, 24 months). Weight varied between 5.3 and 32 kg (mean, 10.3 kg). All patients were symptomatic. Computed tomographic scan was diagnostic and accurately defined the type of anomaly in all the patients. Four patients had a right aortic arch with an aberrant left subclavian artery and left ductus/ligamentum arteriosum, 2 had double aortic arches, and 3 had a right aberrant subclavian artery. One patient developed right-sided pneumothorax on the contralateral site, and another one developed apnea 12 hours after surgery, requiring mechanical ventilation. There was no mortality. Operative time ranged between 50 and 145 minutes, the mean being 107 minutes. The average hospital stay was 4 days. Five patients had their preoperative symptoms completely resolved, and the rest are showing steady improvement. The average follow-up period is 6 months.
Conclusion: Our early experience indicates that thoracoscopic division of vascular rings is safe and effective. Because it takes away the need for thoracotomy, it is likely that it can result in less postoperative pain and rapid convalescence. It also prevents the ill effects of thoracotomy and gives good cosmetic results.

The natural products combretastatins A-1 and A-4 are potent antimitotic and vascular-disrupting agents through their binding at the colchicine site in tubulin. However, these compounds suffer from a low water solubility and a tendency to isomerize to the inactive stilbenes. In this study, we have prepared a series of 18 -restricted triazole analogues of combretastatin A-4 (CA-4), maintaining, in all cases, the 3,4,5-trimethoxy phenyl ring A, with the aim of investigating the substitution pattern on the B-ring in a systematic way.

Aortic arch anomalies represent a range of congenital vascular malformations resulting from disruptions in the typical embryological development of the aortic arch and its branches. These anomalies, which vary widely in their presentation, can lead to significant clinical symptoms depending on their structure and position. We report the case of a 75-year-old male with intermittent hypertension, palpitations, and episodic warmth in the upper body.

Objective: To clarify the role of concentrated growth factors (CGF) in the treatment of periodontal cement defects using calcium phosphate cement (CPC) with self-curing properties.
Methods: Thirty-six intrabony defects were randomly divided into two groups. The experimental group received CGF+CPC treatment (=18), while the control group received CPC treatment alone (=18).

Moyamoya disease (MMD) is characterized by distinct histopathological changes in intracranial arteries, such as narrowing of the arterial lumen due to thickening of the tunica intima, waving of the internal elastic membranes, and thinning of the tunica media. Ring finger protein 213 is a susceptibility gene for MMD that affects clinical outcomes. However, little is known about its relationship with histopathology.

Epidithio-diketopiperazine (ETP) compound is the family of natural fungal metabolites that are known to exert diverse biological effects, such as immunosuppression and anti-cancer activity, in higher animals. However, an enzyme-like catalytic activity or function of the ETP derivatives has not been reported. Here, we report the generation of novel thiol peroxidase mimetics that possess peroxide-reducing activity through strategic derivatization of the core ETP ring structure.
