Objective: The aim of this study was to compare the effect of tourniquet time less than or in excess of 120 minutes on foot surgery wound healing.

Null hypothesis: A tourniquet time of over 120 minutes will not affect wound healing in foot surgery.

Design, setting, participants and method: A retrospective comparative cohort analysis was performed on 96 patients undergoing complex hindfoot surgery in a large central teaching hospital. Fifty-five patients receiving tourniquet pressure for >120 minutes and 41 receiving <120 minutes of tourniquet pressure were identified from electronic case records. The primary outcome was surgical wound healing. Secondary outcomes were discharge date and complication rate.

Results: There was no significant difference in reported time for wounds to heal in the <120-minute or >120-minute cohort. There were no other significant differences in secondary clinical outcomes and no significant variations in patient demographics.

Conclusion: This study suggests that tourniquet times from 2 to 3 hours in foot and ankle surgery with pressures up to 300 mmHg are not associated with a significant effect on wound healing.

Objective: The objective of this study was to identify, among the different anthropometric indicators, the one that shows higher discriminatory power for the prognosis of Obstructive Sleep Apnea Syndrome (OSAS).

Design: Observational cross-sectional study PARTICIPANTS: Obese individuals elective to bariatric surgery METHODS: A study based on data of 758 patients aged ≥ 21 years old, of both sexes, in the pre-operatory stage of the surgical procedure of gastric bypass. Obstructive sleep apnea and obstructive sleep hypopnea were evaluated and classified through the apnea-hypopnea index, which was obtained through the examination of polysomnography. Variables were divided into two groups: individuals with and without OSAS. As predictors, measures of body mass index (BMI), neck circumference (NC), and waist circumference (WC) were used.

Results: The area under the ROC curve was used to check the sensitivity and specificity. All evaluated anthropometric indicators showed statistical significance. WC: area of 0.62 (CI 95%: 0.58 - 0.67), NC: area of 0,68 (CI 95%: 0.64 - 0.72) and BMI: area of 0.58 (CI 95%: 0.54 - 0.63).

Conclusion: The investigated anthropometric indicators performed as good predictors of OSAS. However, NC seems to be the best anthropometric indicator for the prognosis of OSAS in obese individuals when compared to BMI and WC.

Background: Our study objective was to assess if multi-modal analgesia with meperidine-ketorolac combination provides superior analgesia or reduces opioid requirement following surgery compared to Meperidine alone.

Design: Double-blind randomized controlled trial.

Setting: Postoperative pain control in orthopedic ward after spinal anesthesia.

Patients: American Society of Anesthesiology (ASA) risk I or II (ASA I/II) patients who had lower limb implant surgery (88) at our center from September 2014 to July 2015.

Interventions: Patients were randomly assigned to receive either 1 mg/kg of intravenous (IV) meperidine and 30 mg of IV ketorolac (treatment group) or 1 mg/kg of IV meperidine (control group) post-surgery, administered every hour for the first 6 hours during the first 24 hours post-surgery. In addition, patients received intravenous meperidine on an 'as needed basis' during the first 24 hours of the postoperative period.

Measurements: Outcomes were time-to-first analgesia request postoperatively; cumulative opioid dose in first 24 hours post-surgery; frequency of side effects; and patient satisfaction with pain relief using a Likert scale. Numerical rating scale (NRS) pain scores hourly for the first 6 hours, then the 8th, 12th, 16th, 18th and 24th hour post-surgery were assessed.

Results: There was a significant delay in time of first request for analgesia (460 min vs 225 min; P=0.03) and a reduction in opioid consumption in 24 hours (299 mg vs 325 mg; P=0.01) in the meperidine/ketorolac group compared with the meperidine alone group which were both statistically significant. Patient satisfaction with pain relief was better in the treatment group (P=0.01). Additionally, there were fewer side effects in the treatment group than in the control group but this was not statistically significant.

Conclusions: Adding ketorolac to meperidine reduced postoperative pain, reduced patient daily opioid requirement, increased patient satisfaction with pain relief, without increasing the frequency of side effects. Therefore, IV ketorolac addition to opioids may be a reasonable option in multimodal analgesic protocol.

Objective: Sesame allergy is the most prevalent allergy to seeds. Oral immunotherapy (OIT) is defined as continuous consumption of an allergen at special doses and time. Omalizumab (Anti-IgE) increases tolerance to allergens used in OIT. This study evaluated the effectiveness of a new sesame OIT protocol in patients with sesame anaphylaxis in combination with omalizumab.

Methods: In this prospective open-label interventional trial study, 11 patients with a history of sesame anaphylaxis were enrolled after confirmation by oral food challenge (OFC) test. At baseline, skin prick test (SPT) and skin prick to prick (SPP) test were performed. Serum sesame-specific IgE (sIgE) levels were measured. The maintenance phase was continued at home with daily sesame intake for 4 months. At the end of month 4, the OFC and above-mentioned tests were repeated to evaluate the treatment effectiveness.

Results: All 11 patients who underwent sesame OIT after 4 months could tolerate a dietary challenge of 22 ml tahini (natural sesame seed, equal to 5,000 mg of sesame protein and higher) and the average of wheal diameter in the SPT and SPP tests significantly decreased after desensitization.

Conclusion: This OIT protocol may be a promising desensitization strategy for patients with sesame anaphylaxis. Also, omalizumab appears to have reduced the severity of reactions.

Contagion is a function of the properties of the pathogen, social interactions, and personal relationships in the society it attacks. Filmmakers in the horror genre were inspired by the idea of rabies as a virus that could mutate into something more dangerous. Fictional epidemics of scavenging undead were often attributed to encephalitis caused by rabies or a mutated rabies virus. During the early months of the SARS-COV-2 pandemic, there was a spike in streaming of Contagion that portrays a viral infectious disease modeled after a bat virus that spreads at an alarming rate, unleashing a global public panic and a clueless governmental response. We wanted to trace how filmmakers used rabies pathology as source material for their plots. We searched internet film databases and reviewed fictional films that utilized this plot device. Many dystopic, rabies-induced pandemic scenarios - mostly from the zombie genre - reveal parallels to the COVID-19 pandemic. Many zombie films, despite their absurd premise, anticipated the realities of future pandemics.

Background: Nonocclusive mesenteric ischemia (NOMI) is due to mesenteric arterial hypoperfusion from several causes, such as hypovolemia, heart failure, shock, vasoconstrictors, and severe liver or renal disease. Vasoconstrictor-induced NOMI is usually iatrogenic or associated with cocaine use.

Objectives: Anecdotal reports suggest that cocaine-induced NOMI has the highest mortality among vasoconstrictors. This review aims to compare the outcomes of colonic NOMI secondary to cocaine versus other vasoconstrictors.

Methods: We conducted a systematic search of MEDLINE from inception through October 2016 to find articles on colonic NOMI. The study's primary outcomes were mortality and hospital length of stay (LOS), while secondary outcomes included the need for surgery. We reported descriptive statistics as percentages or median and interquartile range (IQR). We compared continuous data with the Mann-Whitney test and categorical data with Fisher's exact test; P < 0.05 was statistically significant.

Results: Of the 59 studies, 20 case reports and 3 case series (n= 27 patients) met the inclusion criteria. There was no difference in mortality between cocaine-induced NOMI and non-cocaine NOMI (P=1.0). There were statistically significant differences between cocaine and non-cocaine vasoconstrictor-induced colonic NOMI regarding surgery (60% vs. 5.8%, P=0.03) and median LOS (7 days vs. 4 days, P=0.04).

Conclusion: Cocaine-induced NOMI and non-cocaine NOMI both appear to have a relatively high but similar mortality rate, but the former is associated with increased requirement for surgery and LOS; prompt recognition of this clinical entity is required to improve outcomes.

Suture-related complications can occur in response to a patient's immune system activation regardless of surgical site. However, there is minimal literature describing complications related to commonly used Polydek sutures. We report the diagnosis, treatment, and follow up of four cases of Polydek suture-related complications post-eyelid lateral tarsal strip procedures, including an early wound healing problem/infection and later granuloma formation and/or suture extrusion that only resolved after removal of the Polydek suture or granuloma tissue. Use of non-Polydek sutures may reduce the likelihood for post-operative suture complications.
