Ultrasound of the salivary glands is indicated for the following: A palpable lump in the gland or neck.Mouth dryness.Pain in the glands.The patient can sometimes palpate a stone under the mandible or under their tongue. The stone can block the duct causing infection and swelling.Mumps or other illness, including mouth or dental infections.Abnormality on previous X-rays, CT or sialogram.Guidance of injection, aspiration or biopsy.Monitoring Sjögren’s syndrome for lymphoma development.
Outdoor Environment Indoor Space

Taking an international flight is much more disruptive to our bodies than most of us are aware of (McIntosh et al. 1998; Hinninghofen and Enck 2006; Spengler and Wilson 2003). Currently, over two billion people, equivalent in number to one-third of the earth’s population, take a commercial flight in a year. We are familiar with minor problems like swelling joints and feet, stuffed ears and aching muscles. Dehydration is also a common problem leading not just to dryness in our skin but also to dry and irritated eyes. We arrive after a long flight exhausted rather than refreshed, despite adopting a position that might be considered to be restful and being entertained, fed and catered to. Our body clock does not easily adapt to a different time zone and the larger the difference in time zones the greater the stress on the body. Often, arriving in a different country means coping with different cultures and expectations as well. The local language can be different and so there is a linguistic adaptation on top of the cultural and biological changes. It is as great and as sudden a cultural and physical shock as we are ever likely to experience.
Chemistry and Biology of Monoglycerides in Cosmetic Formulations

Perhaps the most important attribute required of an oil to be used in a skin lotion is its emollience. The term emollient is applied to those substances which help maintain a smooth, soft, and pliable texture to the skin. In part, this is accomplished by affecting the hydration of skin, namely by preventing or relieving skin dryness. Normal, healthy skin retains its hydration by controlling the transfer of water. With increasing age or in certain disease states where the skin is dry, the phenomenon is associated with increased water loss. Blank has shown that the water content of skin is directly related to slip and flexibility [40].
Study on the solid-liquid separation mechanism of the inverting filter centrifuge’s dewatering process

The engineering simplification methods are efficient and versatile. Most studies[3,4,6,18,21] assume the initial solid concentration of the pre-dewatering stage to be a constant. However, this assumption is illogical when studying centrifugal dewatering processes in a filter centrifuge, where a filter cake with a certain thickness has formed at the feeding stage of the centrifuge cycle. Vorobiev[26] demonstrated that there are significant differences in the one-dimensional dewatering process and dehydration efficiency under different initial conditions, although the final cake dryness is fixed. Therefore, when studying the centrifugal dewatering process, the influence of the feeding stage should be considered.
Symptoms and oxylipins in plasma before and after exposure to rooms in which individuals have both experienced and not experienced building-related symptoms – an exploratory study

Participants with BRS were recruited (n = 51) from the same workplace: a hospital in Northern Sweden with known indoor environmental problems. Individuals with BRS sought medical care because of building-related symptoms between 2014 and 2017 and were examined by a physician. There was no other explanation for their symptoms than the indoor environment (i.e. reported diagnoses were attributed to other causes). The participants then answered a questionnaire that included questions about demographics and physician-based diagnoses, as well as questions about BRS-related symptoms they had experienced at their workplace during the last month, categorised as general symptoms (headache, head pressure, concentration difficulties, tiredness, nausea and dizziness/lightheadedness), mucous membrane symptoms (asthma/wheezing, coughing, throat irritation/hoarseness, dry throat, nasal congestion/discharge, excessive mucus production, nasal mucosa irritation/dryness, sneezing, eye irritation, dry eyes) and skin symptoms (facial itching/stinging/tightness/heat, facial redness, dry facial skin, body itching). The symptoms were rated on a scale that included the following response options: “Yes, every week,” “Yes, sometimes,” “No, never” (See Table 1). Symptoms have been listed by WHO as being of importance for building-related health issues (WHO 1983, 2000) and have been used in previous studies to identify cases of building-related intolerance (Edvardsson et al. 2008).
COVID-19 pandemic and personal protective equipment: Evaluation of equipment comfort and user attitude

The frequency of the physical complaints related to the use of personal protective equipment against the risk of coronavirus disease is shown in Table 4. In addition, 121 participants must wear glasses in their daily life, and 70.2% of them reported that using protective glasses cause difficulty in using their daily eyewear. Moreover, the number of physical complaints related to personal protective equipment was 7.33 ± 2.75 out of 11 physical complaints (Table 4). The most frequently reported physical complaints related to personal protective equipment were dryness, irritation, and scar in the hands. Pain in the face, redness, sores (around the eyes, ears, and nose) and dryness on the throat due to dehydration were the other most frequently reported physical complaints related to the use of personal protective equipment in healthcare professionals (Table 4). There was no difference between “yes” and “no” responders of the presence of the dryness, irritation, scar on the hands in terms of the type protective gloves (p = 0.42). However, the participants complained about the dryness, irritation, and scar on the hands mostly used the disposable non-sterile gloves at 93.5%. There was a statistically significant difference between “yes” and “no” responders of the presence of the pain in the face, redness, sores (around the eyes, ears, and nose) in terms of the type of medical mask (p = 0.001). The participants complained about the pain in the face, redness, sores (around the eyes, ears, and nose), mostly using the N95 mask at 30.7%.
