Obstruction of the superior vena cava (SVC) is a rare complication after cardiac surgery in infants and children. We present the case of an 8-year-old boy who underwent bi-directional Glenn shunt followed by takedown of Glenn shunt and complete repair for cyanotic congenital heart disease. After 4 years of surgery, the child developed features of superior vena caval (SVC) syndrome. Echocardiography and CT angiography revealed complete obstruction of SVC without any forward flow. Transcatheter intervention was performed successfully to re-canalize and stent the SVC to maintain its patency. The patient was doing well at follow-up appointments, with good laminar flow through the stent. In conclusion, transcatheter management of post cardiac surgery SVC obstruction was successful in this patient.

Hypertrichosis is a condition characterized by the presence of an abnormal increase in the number of hairs and either occurs in a localized pattern or a generalized pattern. Localized hypertrichosis around a healing wound is an infrequent postsurgical complication. A 60-year-old Asian man came for a consultation because of an increase in the amount of hair around his 2-month postsurgical wound of right knee arthroplasty. Neither history of topical medications nor systemic medications, which can cause hypertrichosis, were presented. A diagnosis of postsurgical hypertrichosis was made clinically without any laboratory investigations. The patient was reassured that the medication was not necessary and he was appointed for follow-ups. Within the next 4 months, the hypertrichosis resolved spontaneously without any treatment. The case demonstrates the correlation between wound healing and hair morphogenesis, especially as both processes involve some similar growth factors and signaling molecules. Further studies might lead to discovery and better management of hair disorders.

OBJECTIVE: Thiopurines prevent Crohn\'s disease (CD) endoscopic recurrence (ER) at least in 50% of patients 1 year after surgery. This study aimed to evaluate the value of adding mesalazine in patients with subclinical ER despite preventive thiopurine therapy.
METHODS: Crohn\'s disease patients with ileocecal resection treated with thiopurines for postsurgical recurrence prevention in whom mesalazine was added (cases) to treat ER without clinical recurrence (CR) were identified and compared with those in whom no treatment was added to thiopurines (controls). All patients were followed up for at least 1 year from the index endoscopy. Development of CR as well as evolution of mucosal lesions was evaluated.
RESULTS: Thirty-seven patients were included (19 cases and 18 controls). Initial Rutgeerts\' score was i2 in 16 patients (9 cases and 7 controls), and i3 in 21 patients (10 cases and 11 controls). After a median clinical follow-up of 59 months (interquartile range 22-100) from the index endoscopy, six cases (32%) and two controls (11%) developed CR (P = 0.2). After a median time to last endoscopic follow-up of 23 months (interquartile range 17-71), 18 patients (49%) showed improvement in Rutgeerts\' score, 11 patients (30%) demonstrated progression of mucosal lesions, and 8 (22%) had no changes, with no differences between study groups.
CONCLUSIONS: The addition of mesalazine seems to be of no benefit in patients with subclinical endoscopic recurrence while on thiopurine prevention. Moderate endoscopic postsurgical recurrence while on thiopurines may even revert with no additional therapy in some patients.
