Steinert's syndrome presenting as anal incontinence: a case report

<p>Abstract</p> <p>Introduction</p> <p>Myotonic dystrophy (MD) or Steinert's syndrome is a rare cause of chronic diarrhea and anal incontinence. In the presence of chronic diarrhea and fecal incontinence with muscle weakness, neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.</p> <p>Case Presentation</p> <p>We present the case of a 45-year-old Turkish man with Steinert's syndrome, who was not diagnosed until the age of 45.</p> <p>Conclusions</p> <p>In clinical practice, the persistence of diarrhea and fecal incontinence with muscle weakness should suggest that the physician perform an anal manometric study and electromyography. Neuromuscular disorders such as myotonic dystrophy should be considered in the differential diagnosis.</p

ELECTROINITIATED POLYMERIZATION OF N-VINYLCARBAZOLE BY DIRECT ELECTRON-TRANSFER

Electroinitiated polymerization of N-vinylcarbazole has been accomplished by constant potential electrolysis. It was found that direct electron transfer from the monomer to the anode initiates the polymerization even at a potential as low as +0.95 V versus Ag−/ Ag+. Dichloromethane was used as the solvent, and the electrolyte was tetrabutylammonium fluoroborate. Conversions as high as 86% were reached even when a microelectrode was used. Effects of electrode area, temperature, and electrode potential on polymerization were studied. Percent conversion was followed by cyclic voltammetry

Clinical Impact of Preoperative Sentinel Lymph Node Imaging With SPECT/CT in the Management of Interscapular Malignant Melanoma

A 31-year-old male patient with a biopsy-proven cutaneous malignant melanoma located in the interscapular area was referred to lymphoscintigraphy for preoperative sentinel lymph node mapping. Anterior and posterior planar images showed 3 hot spots suggesting left axillary sentinel nodes. Herein, we reported the contribution of preoperative SPECT/CT-guided sentinel lymph node excision on accurate staging, management, prognostic evaluation, and determination of the proper surgical positioning preoperatively
