Wearable devices for remote monitoring of hospitalized patients with COVID-19 in Vietnam.

Patients with severe COVID-19 disease require monitoring with pulse oximetry as a minimal requirement. In many low- and middle- income countries, this has been challenging due to lack of staff and equipment. Wearable pulse oximeters potentially offer an attractive means to address this need, due to their low cost, battery operability and capacity for remote monitoring. Between July and October 2021, Ho Chi Minh City experienced its first major wave of SARS-CoV-2 infection, leading to an unprecedented demand for monitoring in hospitalized patients. We assess the feasibility of a continuous remote monitoring system for patients with COVID-19 under these circumstances as we implemented 2 different systems using wearable pulse oximeter devices in a stepwise manner across 4 departments.

Perforator Mapping of the Superficial and Deep Inferior Epigastric Artery in the Abdominal Region of the Vietnamese.

BACKGROUND: Previous studies worldwide have investigated the anatomy of the perforators of the deep inferior epigastric arteries to figure out the navigation patterns of the perforators on the abdominal wall. This has been inconsistent amongst the researchers about how to select the perforator to increase the blood supply area for the flap. AIM: To explore the blood supply area of the perforators of the superficial and deep inferior epigastric artery in the abdominal region of the Vietnamese by dissection and 64-slice multislice computed tomography (64-slice MSCT). METHODS: A descriptive cross-sectional study Center from September 2014 to September 2016 on two groups including 30 cadavers fixed by formalin 10% in Anatomy Department of UPNT, and 37 patients getting the 64-slice MSCT abdominal arteries angiogram. RESULTS: The superficial epigastric arteries at the level of the inguinal ligament were located in the middle region, with 96% (right) and 88.5% (left). The anterior superior iliac spine level was in the middle, and lateral regions of 68% and 32% respectively. The level of the umbilical cord was in the lateral region with 66.7% and 85.7%, respectively. There were about 6 perforators of the deep inferior epigastric arteries located in the navel area. These perforators were 70% in the medial region and 30% in the middle region. CONCLUSION: Mapping the blood supply based on the fourth space in the abdominal region in which the superfical inferior epigastric arteries supplied the lateral area. The middle and the internal ones were the perforators of the deep inferior epigastric arteries.

The Correlation between the Structures of the Nasal Tip on the Ultrasound and the Anthropometry of the Nose in Vietnamese.

BACKGROUND: Nowadays, there are few types of research held in Vietnam to investigate the anthropometric index of the nose as well as analysis the structure of nasal tip on ultrasound to identify the relationship between these parameters. AIM: To determine the relationship between the height and the width of the nasal tip and the structures constructed these areas by anthropometric and ultrasound measurement. METHODS: A descriptive study in Thanh Van Hospital from December 2017 to April 2019. RESULTS: There were 94 women (62.7%), and 56 men (37.3%) and the average age were 33.6 years old. The height and width of the nasal tip are 10.1 mm and 21.7 mm, respectively. Through the ultrasound, the thickness of the adipose tissues is 3 mm. The width of the interdomal fat pad is 6.5 mm and the distance between two tip point is 5.6 mm. There are the relationships between the distance of two tip points and the width of the tip (r = 0.341), and the width of the interdomal fat pad (r = 0.72). There is also the correlation between the width of the nasal tip with the distance of two tip points (r = 0.46) and the height of the tip with the thickness of the interdomal fat pad (r = 1.23). CONCLUSION: The thickness of the interdomal fat affects the height of the tip, and the distance of two tip points influences the width of the tip.

Research on Macroanatomic and Histologic Characteristics of the Lower Lateral Nasal Cartilages in Vietnamese.

BACKGROUND: There are recently many studies about the anatomy of lower lateral cartilage (LLC). However, the microanatomic studies to identify the segments of most LLC at the nasal tip in Vietnamese are very rare. AIM: Investigate the macroanatomic and microanatomic characteristics of the LLC and the structures of the nasal tip. METHODS: Descriptive study, 30 cadaver noses fixed by 10% formalin, 2 cadaver noses fixed by HE in 69 Institutes in Vietnam from December 2017 to April 2019. RESULTS: The average length of the medial crus is 12.3 mm on the right and 13.2 mm on the left. The maximum intercrural distance is 10.7 mm. The average length of the dome is 3.7 mm and 3.9 mm on the right and left side separately, with 2 subunits are the domal and lobular segment. The average thickness of the tip points is 1.0 mm. The width of the interdomal and intercrural ligaments are 0.5-fold the height and 2-fold the thickness. The thickness of the interdomal fat pad is 3mm and about 0.5-fold the wide. CONCLUSION: The LLC has 3 parts: intermediate, medial and lateral crus. The microanatomic structures of tip consist of the interdomal ligaments, intercrural ligaments, SMAS and interdomal fat pad.

Anatomical Characteristics of Facial Nerve Trunk in Vietnamese Adult Cadavers.

BACKGROUND: In medical literature, there are few studies provided a precise and detailed description of the facial nerve rami and its branches. AIM: Identify several practical anatomic landmarks related to the facial nerve main trunk and its rami. METHODS: A descriptive study, 30 cadavers in the anatomy department of UPNT from October 2012 to April 2015. RESULTS: The average distance from the mandibular angle to the division of the facial nerve is 40.8 mm, and is 86.6% from range 36 - 50 mm. There is 86.7% case in which the facial nerve is in the lateral of the retromandibular vein, and there is a significant difference about both sides. Eighty percent of the case has the superior and inferior ramus in the lateral to the retromandibular vein. There are 2 cases in which the superior ramus makes the circle of the vein. Eighty percent of the facial nerve is in the lateral to the external carotid artery. CONCLUSION: The distance from the mandibular to the division of the facial nerve is longer. The relationship between the superior/inferior ramus and the retromandibular vein maybe not the same in both sides. In some cases, it makes the circle of the vein to cause some complication in the parotid gland surgery.
