Bleeding in Uremia
2021
Progressive deterioration of renal function eventually leads to uremia, which is associated with impaired function of platelets and a disturbed platelet–vessel wall interaction thus increasing the risk of bleeding in patients with renal failure. Furthermore, also anemia and anticoagulants/antiplatelet drugs contribute to the increased risk of bleeding in patients with end stage renal disease. Management of bleeding episodes in uremic patients includes an adequate dialysis, the correction of anemia with erythropoietin or erythropoetin stimulating agents, the administration of estrogens, desmopressin, fresh frozen plasma, cryoprecipitate, factor VIIa, or tranexamic acid. In severe bleeding ep…
The Effect of Dexamethasone on Water and Electrolyte Content and on rCBF in Perifocal Brain Edema in Man
1972
The results of clinical studies are reported dealing with the relationship between cerebral edema and regional cerebral blood flow in patients with brain tumor as well as with the effect of dexamethasone on this relationship. rCBF is found to be significantly reduced in brain tissue surrounding brain tumors. Autoregulation as well as cerebrovascular reactivity to PaCO2 is focally or generally impaired. Water content of perifocal white matter is markedly increased. The combination of tissue lactacidosis, low regional blood flow and vasoparalysis seems to be a characteristic finding in this type of local brain edema. The increased local tissue pressure, due to the increased tissue water conte…
Rechte und Pflichten des Radiologen bei der Indikationsstellung und Anwendung radiologischer Verfahren
2008
A radiological examination or an interventional procedure is a medical invasion of the patient's freedom and does not constitute an offense of causing bodily harm there is a medical indication, when the patient has given consent after being adequately informed, and the intervention is carried out in accord with the valid rules of medical conduct. During the assessment of possible contraindications, the radiologist must also evaluate the indicationy, i.e., he or she must decide if the medical question can be answered by the requested radiological examination. The indication must be viewed the more critically the greater the risk for a complication is. A radiological diagnosis with the use of…
Outpatient minor oral surgery in patients with hemophilia: A case series of 23 patients
2019
Hemophilia is an inherited coagulation disorder characterized by deficiency of the coagulation factor VIII or IX. When the management of hemostasis is inadequate, these patients are at high risk of experiencing intra and postoperative bleedings after tooth extractions. Coagulation factor replacement therapy allows performing most surgical procedures safely, although the factor levels and length of treatment have not been clearly determined. In this study, we present our experience in a retrospective series of 112 ambulatory tooth extractions under local anesthesia in 23 patients with hemophilia using a coagulation factor replacement therapy in combination with tranexamic acid. The results o…
A case of hypocalcemia
2011
Hypocalcemia is a common disorder in the elderly, affecting 10% of the elderly population as a whole, 18% of those in hospital and 36% of those in long-term care [1, 2]. Many conditions can lead to hypocalcemia in adults young and old, e.g. primary hypoparathyroidism, chronic renal failure, gastrointestinal diseases (such as celiac disease or Crohn’s disease), drugs (particularly diuretics, bisphosphonates and antiepileptics), acute pancreatitis and thyroid surgery. Rare causes of hypocalcemia include isolated vitamin 1.25(OH)D3 deficiency or vitamin 1.25(OH)D3 resistance. Another, often neglected cause of hypocalcemia relating to functional parathyroid deficiency is hypomagnesemia. Magnesi…
Physical activity compensates for increased mortality risk among older people with poor muscle strength
2006
The aim of the study was to determine whether habitual physical activity can compensate for the increased mortality risk among older people with poor muscle strength. Mortality was followed up for 10 years after laboratory examination in 558 community dwelling 75- and 80-year-old men and women. Maximal isometric strength of five muscle groups was measured and tertile cut-off points were used to categorize participants. Participants, who reported moderate physical activity for at least 4 h a week, were categorized as physically active and the others as sedentary. High muscle strength and physical activity both protected from mortality, but their effect was not additive. Within each muscle st…
Post-mortem Foetal Imaging
2019
The gold standard for the diagnosis of foetal death is known to be the autopsy examination, which is sometimes supplemented by chromosomal and/or genetic studies. Nevertheless, autopsy rates are continuously declining, due to multifactorial and complex reasons, even anatomical, social and psychological ones, thus impacting the rate of radiological post-mortem foetal examinations.
The Risk of Medical Exposure in Emergency Units in South-West Romania
2013
Background The aim of the paper is to reduce the risk associated with medical exposure to ionising radiations by improving the quality of the radiological activity. A special attention is paid to the possible biological effects of ionising radiations lately, an attitude which is justified by the continual increase of the exposed persons and the doses in-taken by these. Before any X ray examination of the patients it is better to analyse the ratio between the benefits for …
Does the Artery-first Approach Improve the Rate of R0 Resection in Pancreatoduodenectomy? A Multicenter, Randomized, Controlled Trial
2019
[Objective]: To compare the rates of R0 resection in pancreatoduodenectomy (PD) for pancreatic and periampullary malignant tumors by means of standard (ST-PD) versus artery-first approach (AFA-PD). [Background]: Standardized histological examination of PD specimens has shown that most pancreatic resections thought to be R0 resections are R1. “Artery-first approach” is a surgical technique characterized by meticulous dissection of arterial planes and clearing of retropancreatic tissue in an attempt to achieve a higher rate of R0. To date, studies comparing AFA-PD versus ST-PD are retrospective cohort or case-control studies. [Methods]: A multicenter, randomized, controlled trial was conducte…
1583 Clinical and Ultrasound Examination after Unilateral Orchiopexy
2012
Aim To compare testis volume and ultrasound texture post unilateral orchiopexy with the other side. Methods Clinical re-examination and ultrasound measurement of testicle volume and echostructure were performed in 99 children after unilateral orchiopexy, performed between 2003 and 2007. Results Intraoperatively, 30 testis were described as hypoplastic. further 5 patients displayed pathologic funicular structures. On Follow-up clinical exam, 45 patients displayed a small or atrophic testis on the side of surgery. In 10 patients, the testis was described as bigger on the side of surgery. On ultrasound, 65 patients had similar pictures on the side of surgery compared to the other side. In the …
