“…The best option for CVC placement will continue to be US‐guided techniques performed or supervised by trained health care professionals. However, many centers, especially in global south countries (regions outside of Europe and North America, that have economic and health inequities and are economically, politically, or culturally marginalized), or public institutions may lack resources and tools like the US (Quiroga‐Garza et al, 2022). Added techniques such as the use of anatomical landmarks, TP, and HR can improve patient safety and outcomes, and should be considered when patient condition and environment allow it (Tapia‐Nañez et al, 2022).…”

Trendelenburg (Head‐Down tilt) and head rotation: Ultrasonographic effects on the internal jugular vein for catheterization safety

et al. 2022

Most guidelines fail to specify patient positioning during central venous catheterization. The objective was to determine the effects of head‐down tilt (Trendelenburg position) and head rotation on the internal jugular vein (IJV). A prospective, observational, longitudinal, and descriptive study using healthy adult volunteers, of both sexes, was performed. The change in position and cross‐sectional areas (CSA) of the right IJV and common carotid artery (CA) were measured by ultrasonography during Trendelenburg position (TP) (0°, 5°, 10°, and 15°) and contralateral head‐rotation (HR) (0°, 45°, and 90°) for a total of 12 positions. The neutral supine position was first, randomizing the other 11 positions, with 5‐min rest intervals in between. Vital signs and symptoms were recorded. A total of 54 volunteers were recruited between the ages of 21 and 32, of which 30 were men. Any degree of TP or HR significantly increased the CSA. The largest area obtained was 1.78 cm2 with a TP15HR90 which did not have a statistical difference with TP10HR45 1.59 cm2. A HR90 tended to displace the IJV medially, overlaying the CA. Any degree of TP or HR will significantly increase CSA or the right IJV. A 5° to 10° TP is recommended when the patient's condition allows it, with a 45° HR, without significantly displacing the IJV anterior to the CCA.

“…The procedure may be well under-reported, as it is performed by different surgical professionals ranging from dentists, maxilo-facial surgeons, and aesthetic plastic surgeons [22]. The procedure, although simple and managed as out-patient, should be performed by trained personnel, as it can present important complications [19,21,25].…”

Purpose: To determine the volume of the buccal fat pad (BFP), and its relationship with the upper 2nd molar and the facial artery (FA). Methods: A cross-sectional, observational study. Computed tomography was used to obtain 3D images to determine volume, length, and width. Distances from the 2nd molar to each extension, and the nearest distance to the FA. Results: A total of 106 BFP (70 male) were included. The mean age was 51±21. The mean volume, length, and width were 13.8±5.4mL, 72.9±10.7mm, and 21.4±5.6mm, respectively. The BFP extends mainly cephalic and caudally from the second molar, reaching upto 8.5 cm and 32mL. The mean distance between the second molar and FA was 12.9mm, but as close as 3mm. The FA had a mean distance of 2.1mm to the nearest BFP extension, with 42.5% in intimate contact, and another 9.4% crossing the center of the masseter extension. There were no statistically significant differences between sexes. Conclusions: The BFP has a dynamic shape with highly variable size and volume. Although removed for cosmetic procedures or reconstructive purposes, the FA is often at risk of damage during procedures due to its proximity. Procedures must be performed by highly trained medical professionals with anatomical knowledge of its morphometry and variability.

Psidium guajava L.: From byproduct and use in traditional Mexican medicine to antimicrobial agent

et al. 2023

Mexico is one of the largest guava producers in the world, so it has access to a huge amount of waste and byproducts obtained after the industrial processing of the fruit. This review discusses the potential recovery of this residue for its application as an antimicrobial agent, considering the phytochemical composition, the bioactivity reported in-vivo and in-vitro, and the toxicology of the plant. Nowadays there is a growing demand for more natural and safer products, so the use of guava extracts is an interesting initiative, especially due to its availability in the country, its wide variety of traditional uses, and its phytochemical profile. This review highlights the importance and potential antimicrobial use of this plant in today's world.
