BACKGROUND Although laparoscopic sleeve gastrectomy is known, in general, to improve renal function in patients with obesity and chronic kidney disease (CKD), its effect on estimated glomerular filtration rate (eGFR) stratified by the stage of CKD is less clear. OBJECTIVES We aimed to evaluate the impact of sleeve gastrectomy on renal function in a stratified cohort of patients with CKD. SETTING University Hospital. METHODS We performed a retrospective review of 1932 patients who met National Institutes of Health's guidelines for metabolic surgery and underwent laparoscopic sleeve gastrectomy performed by 1 of 3 surgeons. One hundred sixty-four patients with CKD stages 1 through 4 were identified. RESULTS Mean follow-up period was 1.57 ± 1.0 years. Mean age was 56.4 ± 9.9 years with a preoperative body mass index of 47 ± 9 kg/m2, which decreased to 38.9 ± 8.7 kg/m2 at most recent follow-up (P less then .001). In the cohort of patients with diabetes, significant decreases were observed in mean glycated hemoggression to end-stage renal disease. PURPOSE Thumb carpometacarpal (CMC) joint arthroplasty is one of the most commonly performed surgeries by hand surgeons. A large portion of these patients also have scaphotrapezoidal (ST) arthritis in addition to CMC arthritis. The purposes of this study were to quantify the amount of transverse trapezoid resection necessary to prevent ST impingement and to compare an oblique with a transverse osteotomy of the trapezoid. METHODS A total of 9 cadaveric specimens were used and were randomly placed into 2 groups. Group 1 had sequential transverse osteotomies and the space between the scaphoid and trapezoid was measured in various wrist positions. Group 2 had oblique osteotomies and the ST distance was measured in multiple wrist positions. RESULTS In group 1, there was no contact between the scaphoid and trapezoid in neutral wrist position after any resection. The half and two-thirds transverse osteotomies did not have contact at 20° radial deviation (RD) and 30° wrist flexion (WF). In 1 of the 5 specimens, thereitis, an oblique osteotomy of the trapezoid may prevent impingement while allowing for less overall bony resection compared with a transverse osteotomy. A new classification for congenital upper-extremity anomalies was first published in 2010. It has come to be known as the OMT classification highlighting the thought leaders behind it Kerby Oberg, Paul Manske, and Michael Tonkin. Based on a dysmorphology framework, the OMT has been adopted by the International Federation of Society for Surgery of the Hand and surgeons who treat congenital upper-extremity anomalies. As predicted in the first publication, updates will be necessary based on an improved understanding of morphogenesis; the first update was in 2014 and this represents the second update to the original OMT classification. We carefully reviewed all aspects of the OMT classification, its current stratification, and updated literature on the developmental basis of limb anomalies. We also considered the clinical usefulness and challenges of the classification through discussions with stakeholders and those who care for patients with congenital upper-limb anomalies. These factors guided the current modifications of the OMT classification. In providing the updated classification, we provide the rationale for these changes. The updated OMT classification is by no means final. As our understanding of congenital anomalies progresses, we anticipate subsequent updates in the years to come. PURPOSE With radial nerve lesions, the results of nerve transfers and how they objectively compare with the outcomes of tendon transfers remain unstudied. We compared the results after nerve transfer in patients with less than 12 months since radial nerve injury with the results after tendon transfer in patients not eligible for nerve surgery because of longstanding paralysis (minimum of 15 months). METHODS In 14 patients with radial nerve lesions incurred less than 12 months previously, we transferred the anterior interosseous nerve to the nerve of the extensor carpi radialis brevis (ECRB), while the nerve to the flexor carpi radialis was transferred to the posterior interosseous nerve. In 13 patients with lesions of longer duration, we transferred the pronator teres tendon to the ECRB, the flexor carpi ulnaris tendon to the extensor digitorum communis, and the palmaris longus to the rerouted extensor pollicis longus (EPL) tendon. At a final evaluation, we measured passive and active range of motion (ROM) of remains for improved thumb motion with both procedures. TYPE OF STUDY/LEVEL OF EVIDENCE Therapeutic IV. BACKGROUND When introducing a microguidewire into an occluded vessel during mechanical thrombectomy (MT), visual information on the vessel course distal to the occluded site could help to avoid perforation. We examined whether visualization of the middle cerebral artery (MCA) by coronal images of nonenhanced computed tomography (coronal CT) provides useful preoperative information on the vessel course in the setting of MT. METHODS AND RESULTS We retrospectively studied 29 patients with ischemic stroke of the internal carotid artery and MCA occlusion who were admitted to our hospital within 4.5 hours from stroke onset and underwent MT. Coronal CT images were preoperatively created by a dedicated workstation and adjusted to visualize the M1 segment of the MCA (M1) and nearby areas.  https://www.selleckchem.com/products/mivebresib-abbv-075.html  We referred to these images while performing MT. The shape and course of M1 on preoperative coronal CT images were compared with that in intraoperative angiography after recanalization. The median time from the start of imaging to arterial puncture was 40 minutes (interquartile range 32.5-55.0 minutes). Successful recanalization of the thrombolysis in cerebral infarction 2b-3 was achieved in 89.7% of patients. The degree of matching was assessed as moderate to excellent, and was useful as preoperative information in 27 (93.1%) patients. CONCLUSIONS Preoperative information on the vessel course by coronal CT well matched that in the intraoperative angiography. Only a little extra time and a small additional procedure are necessary for this technique. The addition of coronal CT images could contribute to a safe and successful MT.
