Diagnosis and treatment of post-traumatic hypothermia in hospitals - a pilot study.

BACKGROUND: An unintentional drop in core body temperature of trauma victims is associated with increased mortality. Thermoregulation is impaired in these patients, especially when treated with opioids or anesthetics. Careful thermal insulation and active warming are necessary to maintain normothermia. The aim of the study was to assess the equipment and procedures for diagnosing and managing post-traumatic hypothermia in Polish hospitals. METHODS: Survey forms regarding equipment and procedures on monitoring of core temperature (Tc) and active warming were distributed to every hospital that admits trauma victims in the Holy Cross Province. Questionnaires were addressed to surgery departments, intensive care units (ICUs), and operating rooms (ORs). RESULTS: 92% of surgery departments did not have equipment to measure core body temperature and 85% did not have equipment to rewarm patients. Every ICU had equipment to measure Tc and 83% had active warming devices. In 50% of ICUs, there were no rewarming protocols based on Tc and the initiation of rewarming was left to the physician's discretion. In 58% of ORs, Tc was not monitored and in 33% the patients were not actively warmed. CONCLUSIONS: The majority of surveyed ICUs and ORs are adequately equipped to identify and treat hypothermia, however the criteria for initiating Tc monitoring and rewarming remain unstandardized. Surgery departments are not prepared to manage post-traumatic hypothermia.

Urine NGAL is useful in the clinical evaluation of renal function in the early course of acute pancreatitis.

INTRODUCTION: Acute Kidney Injury (AKI) is a serious early complications in patients with acute pancreatitis (AP) that signifcantly increases mortality rates compared to patients without AKI. The early diagnosis of AKI during its treatable phases and implementation of appropriate treatment protocols can improve outcomes for this group of patients. A promising biomarker for AKI is neutrophil gelatinase-associated lipocalin (NGAL). AIM: This study evaluated the diagnostic value of NGAL concentrations in serum and in urine for patients developing AKI as an early complication of AP compared to AP patients without AKI. MATERIAL AND METHODS: The study group composed of 65 patients (34 men and 31 women) with a mean age of 62.2 ± 16 years with AP and hospitalized in the Surgery Department of the Direct Hospital in Sucha Beskidzka, Poland between January and December 2014. Serum NGAL (sNGAL) levels were measured with the BioVendor ELISA kit, and urine NGAL (uNGAL) with the Abbott ARCHITECT Analyzer. RESULTS: In the early phase of AP, 11 patients (17%) developed AKI, including 10 patients with stage 1 and one with stage 2. AKI was associated with more severe AP, higher BISAP scores, the need for more intensive treatment, longer hospital stays and higher mortality. Both serum and urine NGAL concentrations were signifcantly higher in patients with AKI throughout the study and signifcantly predicted AKI in simple and multiple logistic regression adjusted for age, sex and comorbidities. Serum and urine NGAL concentrations were signifcantly correlated with levels of serum urea, creatinine, urine albumin, and the maximum change in serum creatinine. Serum and urine NGAL levels also correlated positively with direct neutrophil counts and CRP concentrations throughout the study. CONCLUSIONS: The measurement of NGAL levels, particularly in urine, is simple, easy to interpret, routinely available, and clinically useful in the assessment of dynamic changes in kidney function for patients with AP.

Blood vessels of the shin - anterior tibial artery - anatomy and embryology - own studies and review of the literature.

Injuries of the lower leg are rather frequent in every day orthopedic routine. Process of healing takes quite a long time and is commonly dependent on the proper vasculature. e study was carried out on 50 human lower legs obtained during autopsies. The anatomy of the vascular system of the leg was studied using classical anatomical dissection methods. Based also on literature we have reviewed the current knowledge on the vascularization of the lower leg and its embryological background.

Formalin use in anatomical and histological science in the 19th and 20th centuries.

The introduction of formalin, a formaldehyde solution, as a disinfectant and fixative was an essential improvement in anatomical and histological science. This paper is an outline of the historical use of formalin based on primary source texts and historical studies. We describe how the discovery of acetaldehyde in the 18th century led to the development of formalin as the most common ingredient in embalming fluids in the 20th century and is still used today. Particularly important contributions to this process were made by Justus von Liebig, Alexander Butlerow and August Wilhelm Hofmann in the development of anatomical and histological preparation techniques, and by Ferdinand Blum, Ferdinand Julius Cohn, Frederick C. Kenyon and Victor Wehr in the practical uses of formaldehyde solutions in preservation and fixation of soft tissues. However, formalin is not without its drawbacks and as its toxicity became more understood, method to mitigate its effects were demanded. Eventually safer preparation techniques were developed, including Hagens' plastination and Thiel Embalming Method. These techniques may someday largely replace high-concentration formalin solutions but they both still require at least small quantities of formaldehyde to preserve tissues for study.
