PURPOSE: There are many risk factors for postoperative acute kidney injury in liver transplantation. The aim of this study is to investigate the risk factors for postoperative acute kidney injury in living donor liver transplantation recipients. METHODS: 220 living donor liver transplantation recipients were retrospectively evaluated in the study. According to the Kidney Disease Improving Global Outcomes Guidelines, acute kidney injury in postoperative day 7 was investigated for all patients...

OBJECTIVE: Vitamin D is a fat-soluble vitamin that plays a major role in the regulation of bone and calcium metabolism and has effects on the immune and cardiovascular systems. Vitamin D deficiency is commonly seen in the general population as well as in critically ill patients and is reported to be associated with increased mortality and morbidity. Our aim was to determine the relationship between vitamin D level at ICU admission and mortality. METHODS: A total of 491 patients admitted to the ICU between January 2014 and January 2015 were evaluated retrospectively...

BACKGROUND/AIM: Calculation of the chloride:sodium (Cl(-):Na(+)) ratio is proposed to enable a quick evaluation of the effect of Cl(-) and Na(+) on the acid-base balance in critically ill patients. In the present study, the relationship of the Cl(-):Na(+) ratio of septic patients with acid-base status and ICU mortality were investigated. MATERIALS AND METHODS: In our two-center study, 434 patients who were diagnosed with sepsis were included. The patients were divided into three groups: low (<0...

AIM: Chordomas are rare, slow growing but locally aggressive malignancies of the axial skeleton. Skull base chordomas, due to their intricate anatomical localization pose significant challenges to managing physician. In classical and chondroid chordomas the disease course cannot be reliably determined using only morphological criteria. Brachyury (T Gene) was shown to play a central role in chordoma pathogenesis and several studies have also shown that this gene also caries potential as a prognostic biomarker...

OBJECTIVES: Elective tracheotomy (ET) procedures in intensive care units (ICU) might be different in accordance with countries and ICUs' features. The aim of the present study was to search the epidemiology of ET procedures in Turkey. METHODS: A questionnaire which consists of 43 questions was sent by e-mail to 238 ICUs which were officially recognized by The Turkish Ministry of Health. All answers were obtained between August 1, 2015 and August 31, 2015. RESULTS: Two hundred and three ICUs (85...

PURPOSE: The recommended method for elucidating the effects of strong ions other than lactate on acid-base balance is to calculate the non-lactate strong ion difference (SIDnl). A relationship between HCO3 (-) and SIDnl in hyperchloremic patients has already been demonstrated; in the present study, the relationships between SIDnl, the apparent strong ion difference (SIDa), and mortality at intensive care unit (ICU) admission were investigated. METHODS: In our two-center study, 2691 patients admitted to the ICU were retrospectively evaluated, including 1069 critically ill patients...

OBJECTIVES: Sepsis is one of the most common reasons of increased mortality and morbidity in the intensive care unit. The changes in CRP levels and hemogram parameters and their combinations may help to distinguish sepsis from non-sepsis SIRS. The aim of this study is to investigate the CRP and hemogram parameters as an indicator of sepsis. METHODS: A total of 2777 patients admitted to the ICU of two centers between 2006-2013 were evaluated retrospectively. The patients were diagnosed as SIRS (-), non-sepsis SIRS and sepsis...

INTRODUCTION: Sleep apnea-hypopnea syndrome (SAHS) is one of the extracardiac reasons of atrial fibrillation (AF), and the prevalence of AF is high in SAHS-diagnosed patients. Nocturnal hypoxemia is associated with AF, pulmonary hypertension, and nocturnal death. The rate of AF recurrence is high in untreated SAHS-diagnosed patients after cardioversion (CV). In this study, we present a patient whose SAHS was diagnosed with an apnea test performed in the intensive care unit (ICU) and who did not develop recurrent AF after the administration of standard AF treatment and bi-level positive airway pressure (BiPAP)...

INTRODUCTION: Pulmonary alveolar microlithiasis (PAM) is an autosomal recessive disease characterized by the deposition of phosphate and calcium in the alveoli. The disease progresses asymptomatically until later stages. When it becomes symptomatic, lung transplantations performed before the onset of right heart failure may improve life expectancy and quality. Here we present a case report concerning the very first Turkish PAM patient to have undergone lung transplantation surgery. Patient information: A 52 year-old female, Caucasian patient, already diagnosed with PAM in infancy, was admitted to the intensive care unit, diagnosed with pneumonia and hospitalized for 20 days...

INTRODUCTION: ApneaLink™ (RESMED-Munich, Germany) is a simple and inexpensive device that determines the apnea-hypopnea index. The sensitivity and specificity of the apnea-hypopnea index are 100 and 87.5%, respectively. Our hypothesis can be used to create a treatment plan using the apnea-hypopnea index for intensive care unit patients. CASE PRESENTATION: This treatment plan has been created by determining the apnea-hypopnea index of eight Caucasian patients with a variety of diagnoses...

Smuggling drugs by swallowing or inserting into a body cavity is not only a serious and growing international crime, but can also lead to lethal medical complications. The most common cause of death in 'body packers', people transporting drugs by ingesting a packet into the gastrointestinal tract, is acute drug toxicity from a ruptured packet. However, more than 30 years after the initial report of body packing, there is still no definitive treatment protocol for the management of this patient group. The treatment strategy is determined according to the particular condition of the patient and the clinical experience of the treatment center...

Posttraumatic pulmonary arteriovenous fistula is a rare complication of penetrating injury. Cases may remain asymptomatic for years prior to diagnosis. We present a case of pulmonary arteriovenous fistula related to a penetrating injury of the thorax 6 years previously that was occluded with a septal occluder device. Consistent use of CT or conventional catheter pulmonary angiography following penetrating injury to the thorax is essential to the early diagnosis of pulmonary arteriovenous fistula during the asymptomatic stage...
