Article Synopsis
  • - This study looked at how the COVID-19 pandemic affected midfacial fracture patterns in a German trauma center, comparing cases from before (Feb 2019-Jan 2020) and during (Feb 2020-Jan 2021) the pandemic.
  • - Results showed a decrease in total midface fractures during the pandemic (88 pre-COVID vs. 57 during), with more falls and home accidents but fewer sports injuries and violence-related fractures.
  • - The study suggests that the changes in fracture circumstances and increased hospital wait times during COVID-19 could help inform future treatments for facial injuries in similar situations.

An increase in the renal resistive index (RRI) in patients with essential hypertension (EH) predicts deterioration in renal function. In patients with EH, changes in hemodynamic parameters significantly affect the RRI. This study aimed to define changes in Ambulatory Blood Pressure Monitoring (ABPM) parameters that are significantly associated with a change in RRI in patients with EH.

Introduction: Hyponatraemia is associated with increased mortality in patients undergoing maintenance haemodialysis. In anuric patients, hyponatraemia development depends on the water-sodium ratio in retained fluid within the interdialysis interval (IDI).

Objective: This study aimed to calculate the retained sodium-retained water ratio in patients on maintenance haemodialysis and make a differential diagnosis of hyponatraemia according to these data.

Objective: Respiratory alkalosis (RA) and dilutional hyperchloremic acidosis (DHA) are the most common acid-base balance (ABB) disorders in patients with liver cirrhosis. The aims of this study were to clarify whether RA develops in relation to DHA via respiratory compensation of metabolic acidosis and whether spironolactone in combination with low-dose furosemide - diuretics known to ameliorate DHA - positively affects RA in liver cirrhosis patients.

Materials And Methods: 59 patients with advanced cirrhosis were divided into two groups.

In patients with advanced cirrhosis with ascites disorders of water and electrolyte metabolism are often present and they are associated with changes in acid-base balance. These changes can be very complicated, their diagnosis and treatment difficult. Dilutional hyponatremia is the most common disorder.

Changes to the overall volume of body water and acid base equilibrium can be reflected in the values of differences and ratios relating to serum concentrations of natrium and chlorides. Both these quantities can be used for patients with hyponatremia in the hyponatremia differential diagnosis. This paper presents a case study which is an example of the clinical use of differences in and ratios of serum concentrations of natrium and chlorides when monitoring effectiveness of the therapy.

Metabolic acidosis (MAC) is a constant symptom of chronic kidney disease (CKD) in advanced stages. However, its onset and degree do not depend only on the decrease of glomerular filtration but also on tubular functions. Therefore, in patients with predominant tubulointerstitial involvement it may already appear in earlier stages of CKD, usually as MAC with normal anion gap.

Two approaches have been used in clinical evaluation the acid-base status: traditional (bicarbonate-centered) is based on the Henderson-Hasselbalch equation complemented by calculation of the anion gap, and more recent quantitative approach proposed by Stewart and Fencl. The latter method defines the three independent variables, which regulate pH. These include: the difference between the sum of charges carried by strong plasma cations and anions termed the strong ion difference - SID (decrease causes acidosis, and vice versa); the total concentration of the weak non-volatile acids [Atot] (inorganic phosphate and albumin, decrease causes alkalosis and vice versa), and pCO2.

Unlabelled: The differential diagnosis of hyponatremia is often difficult. This most frequently occurring disorder of the water and electrolyte metabolism is frequently connected with deviations relating to the acid-base balance (ABB). This survey analyzes the relationship between the changes of the volume of body fluids and ABB and infers to what extent the analysis of combinations of the two disorders can support the differential diagnosis of different forms of hyponatremia (differentiation between the dilution vs.

Introduction: Moderate to medium decrease in glomerular filtration (GFR) in individuals with chronic kidney disease (CKD) does not need to be associated with hyperphosphatemia due to an adaptive decrease in tubular reabsorption of phosphates (TRPi) in residual nephrons. The clinical assessment of this function is performed based on the measurement of fractional phosphate excretion (FEPi), which is a quantity specifying the proportion of the filtered amount of phosphates which is excreted in the urine. This quantity may provide useful information about the involvement of kidneys in phosphate homeostasis of the internal environment.

Tubular transport of sodium (TNa+) and chloride (TCl-) is decreased in patients with chronic kidney disease. The decrease of TCl- is relatively lower than that of TNa+. These changes of tubular transport of Na+ and Cl- participate on the development of acid base disturbance in patients with chronic kidney disease and with their glomerular filtration rate lower than 0.
