Connell Suture Not Cause of Death.

Modified Continuous Mucosal Connell Suture for the Pharyngeal Closure After Total Laryngectomy: Zipper Suture

OBJECTIVES Pharyngocutaneous fistula is a serious complication after total laryngectomy, and there are some risk factors stated in the literature. The surgical suture techniques are not studied so much. The aim of this study is to evaluate the effectiveness of 'modified continuous mucosal Connell suture' on the incidence of pharyngocutaneous fistula after total laryngectomy. METHODS This is a...

Cause-of-death certification--not as easy as it seems.

Somatic FGFR and TWIST mutations are not a common cause of isolated nonsyndromic single suture craniosynostosis.

Pathogenic mutations in FGFR2 and TWIST genes are detected in the majority of individuals with Crouzon, Pfeiffer, Apert, and Saethre-Chotzen syndromes. In contrast, mutations have been identified rarely in cases of nonsyndromic, single suture craniosynostosis. Recently, two studies confirming somatic mosaicism with local expression of an FGFR mutation have been reported. This study investigates...

The Connell Sum Sequence

The Connell sum sequence refers to the partial sums of the Connell sequence. In this paper, the Connell sequence, Connell sum sequence and generalizations from Iannucci and Mills-Taylor are interpreted as sums of elements of triangles, relating them to polygonal number-stuttered arithmetic progressions. The n-th element of the Connell sum sequence is established as a sharp upper bound for the v...
