Amputations of diabetic patients from Metropolitan Monterrey Mexico show a seasonal pattern being the winter months those that present highest frequency.

Background:The amputation of an extremity is a main complication of Diabetes mellitus. Worldwide the prevalence of amputations associated with diabetes mellitus is variable and had a considerable impact in the quality of life. Objective: Analyze the frequency of amputations in the University Hospital, Dr José E González and evaluate if a seasonal pattern is present. Method: A retrospective analysis from 2009 to 2012 was carried out. Clinical files of diabetic patients undergoing to amputation were studied. The seasonality was evaluated with a chi square goodness of fit. Results: A total of 456 amputations were studied. Results shown that February was the month with highest frequency of amputations while winter was the annual season with highest frequency of amputations. Conclusions: Amputations of diabetic patients from Metropolitan Monterrey Mexico show a seasonal pattern being the winter months those that present highest frequency.

Introduction: Management of the airway is one of the challenges in anesthesiology; multiple devices and techniques have been developed to manage it, preventing a catastrophic outcome for the patient in different scenarios. Objective: The objective of the study was to demonstrate that our modified laryngoscope, using a cell phone as a screen monitor, is useful and safe in the management of the adult patient's airway. Materials and methods: This was a descriptive, observational, and prospective study, using the modified laryngoscope for intubation in 139 elective patients, with airway check-up, intubation time measurement, number of attempts, observed Cormack-Lehane, percentage of glottis observed (POGO) scale, and adverse events registry. Results: There were 138 patients with successful intubations and one failure. Of these, 66.1% were female, and 33.9% were male, 92% were intubated on the first attempt. About 61% were intubated in 30 s or less and 35% in <1 min, visualization of the glottal ring was 82%, 72% of which were recorded as Cormack-Lehane I, and with POGOs of 100%, the burp maneuver was used to assist in 38%. Conclusions: The device proved to be useful and safe in the management of the patient's airway, with a success rate of 92% in the first attempt.
