Chiari type 1 Malformation (CM 1) is a structural defect consisting of a displacement of the cerebellar tonsils through the foramen magnum causing obstruction of cerebrospinal fluid (CSF) outflow. CM 1 has a variety of presentation with headache being the most common symptom. The evaluation and treatment of headache related to CM 1 are often difficult, because the pain in the occipital-suboccipital region or headache that is of cough-type suggests symptomatic CM 1, but patients suffering from CM 1 can also report migraine or tension-type headache. In 2015 we started a collaborative project in which our group of neurologists, neurosurgeons and neuroradiologists contribute to create a Chiari Special Outpatient Service; this was set up to provide a multidisciplinary evaluation, treatment and follow-up of patient suffering from CM 1. 201 patients (58 males, 143 females) suffering from CM 1 were multidisciplinary evaluated. Headache characteristics, clinical features, and treatment of patients are discussed. Further progress in multidisciplinary care of headache and CM 1 should be performed to define guidelines.

Aim Recent meta-analyses and randomized clinical trials have concluded that mechanical bowel preparation (MBP) before elective colorectal surgery is not associated with a reduction of surgical site infection (SSI). The aim of this randomized clinical trial was to evaluate the impact of preoperative MBP for colon and rectal cancer surgery in comparison with a single glycerine enema. Method Patients scheduled for radical colorectal resection for malignancy with primary anastomosis were randomized to preoperative MBP (4 l of polyethylene glycol) (group 1, 114 patients) plus a glycerine 5% enema (2 l) or a single glycerine 5% enema (2 l) (group 2, 115 patients). The postoperative incidence of SSI was recorded prospectively. Patients undergoing minimally invasive surgery (laparoscopy or robotic) accounted for 55 and 51 in groups 1 and 2 respectively. Results In all, 229 patients were included in the study, 114 in group 1 and 115 in group 2. At least one SSI was reported in 16 (14.0%) group 1 and in 20 (17.8%) group 2 patients ( P = 0.475). Perioperative mortality was nil. The incidence of SSI was comparable also in the 73 patients who had a low anterior resection (seven of 33 vs eight of 40, P = 1.000), and for the 106 patients who underwent a minimally invasive procedure (nine of 55 vs four of 51, P = 0.241). Conclusion A single large-volume glycerine enema is effective bowel preparation before colorectal resection whether performed by an open or minimally invasive technique. [ABSTRACT FROM AUTHOR]
