Cauterization prevents hemorrhage and optimizes the surgical field during endoscopic sinus surgery but may cause injury to nearby structures. The objective of this study is to examine thermal conductance from cauterization equipment across the skull base.

Cadaver and animal model.

Surgical skills laboratory of an academic tertiary medical institution.

A pilot study was conducted with a deidentified cadaver head and expanded to a goat head animal model. Endoscopic dissection was performed to expose the lamina papyracea, ethmoid roof, sphenoid roof, and frontal sinus. Cautery was applied to the frontal sinus of goat heads, and temperatures were measured via thermocouple sensors placed along the intracranial skull base. Surgical instruments studied included monopolar, bipolar, and endoscopic bipolar devices at various power settings.

Temperature increase, as averaged across all cautery powers and measurement positions, was highest for the monopolar cautery (17.55 °C) when compared with the bipolar and during endoscopic sinus surgery.In this nested case-control study, we evaluated haematological and morphological parameters of hospitalised patients with real-time polymerase chain reaction verified COVID-19 infection compared to patients with similar symptomatology but without COVID-19 infection. Seventy-four COVID-19 positive and 228 COVID-19 negative patients were evaluated with routine haematological parameters. Severe disease was defined as death and/or need of intensive care treatment. Twenty-seven COVID-19 positive and 18 COVID-19 negative patients were furthermore included for morphological evaluation using smear examination. Significant differences were found for platelet indices and white blood cell parameters. Thus, platelet count and plateletcrit was lower in COVID-19 patients, whilst mean platelet volume, platelet distribution width, and platelet large cell ratio was significantly higher than in non-COVID-19 patients. Leukocyte, neutrophil, immature granulocyte, lymphocyte, monocyte, eosinophil, and basophil count was lower in COVID-19 patients. No significant differences were found for red blood cell count, haemoglobin, haematocrit or mean corpuscular haemoglobin for COVID-19 versus non-COVID-19 patients. COVID-19 patients with a severe disease course had higher levels of immature granulocytes, but lower lymphocyte and platelet counts compared to patients with non-severe COVID-19. In terms of morphology, 14.8% of COVID-19 patients had a normal smear examination, compared to 83.3% of non-COVID-19 patients. Hypogranulated neutrophils were more frequent in COVID-19 patients (p  less then  .001), but non-COVID-19 patients had higher levels of reactive lymphocytes, compared to COVID-19 patients. In conclusion, several haematological morphological abnormalities are more frequent in patients with COVID-19 disease, and several findings indicate that platelets play a fundamental role in the pathophysiology of the disease.Heat generation during bone cutting by sagittal saw may lead to temperature rise and possible incidence of thermal necrosis. The aim of the present research is to examine the effect of saw blade oscillation rate, blade feed rate, and irrigation by physiological saline solution on the bone temperature rise during sawing in order to determine the desired conditions for reducing the extent of thermal damage. For this purpose, empirical tests of bovine femur cutting were performed in 15 states, including five levels for the blade oscillation rate (10,000-18,000 cpm with 2000 cpm intervals) and three levels for the feed rate (10-30 mm.min-1 with 10 mm.min-1 intervals) for dry conditions; and five states, including five levels for the blade oscillation rate (10,000-18,000 cpm with 2000 cpm intervals) and one level in feed rate of 20 mm.min-1 for the irrigation conditions. The results indicated that the bone temperature rise had a direct relationship with the blade oscillation rate and an inverse relationship with its feed rate. find more In the state of no cooling, the minimum temperature rise (ΔT = 65.45°C) occurred at the blade speed of 10,000 cpm and feed rate of 30 mm.min-1, while in the state of sawing with irrigation, the temperature rise almost did not exceed the allowable range (ΔT ≤ 10°C). The results suggested that to lower the possibility of incidence of osteonecrosis in the bone resection by sagittal saw, cooling with physiological saline solution or application of the minimum blade oscillation rate and maximum feed rate is recommended.With the onset of the COVID-19 pandemic, social distancing guidelines have reshaped the way that we live our lives. Perhaps the most common and strictly adopted measure has been mask wearing. Mask wearing, whether it be cloth, surgical, or N95, has quickly become the new norm in the ongoing struggle against this pandemic and has been proven to be effective in curbing its high infection rate. There has, however, been growing opposition to these policies by a substantial part of the general population who claims that masks are ineffective and can worsen breathing. To some, the choice to use or not use a mask has morphed into a point of political contention, rather than a choice rooted in concerns for public health. This commentary attempts to investigate the validity of these claims and explore how clinicians can encourage the usage of masks despite the fears and confusion against them.
The purpose of this meta-analysis was to evaluate the overall safety and effectiveness of perioperative intravenous dexamethasone to facilitate postoperative rehabilitation in patients after total knee arthroplasty (TKA).

A comprehensive literature search was performed using the Embase, PubMed, Cochrane Library, and China National Knowledge Infrastructure (CNKI) databases for relevant randomized controlled trials (RCTs) from inception to 2020. Methodological quality of the trials was assessed using the Cochrane Risk of Bias Tool, and the relevant data were extracted using a predefined data extraction form.

Ten RCTs with 1100 knees were included. Our study showed a significant reduction in pain using a postoperative pain visual analog scale (VAS) at 24 hours and 48 hours, total opioid consumption at 24 hours and 48 hours, postoperative nausea and vomiting (PONV), active range of motion (ROM) limitation, and passive ROM limitation at 72 hours in dexamethasone-treated groups compared with controls.

Intravenous low-dose dexamethasone is potentially useful in the perioperative setting for reducing postsurgical immediate ROM limitations, pain, opioid consumption, and PONV.
