EPIdemiology of Surgery-Associated Acute Kidney Injury (EPIS-AKI) : Study protocol for a multicentre, observational trial

More than 300 million surgical procedures are performed each year. Acute kidney injury (AKI) is a common complication after major surgery and is associated with adverse short-term and long-term outcomes. However, there is a large variation in the incidence of reported AKI rates. The establishment of an accurate epidemiology of surgery-associated AKI is important for healthcare policy, quality initiatives, clinical trials, as well as for improving guidelines. The objective of the Epidemiology of Surgery-associated Acute Kidney Injury (EPIS-AKI) trial is to prospectively evaluate the epidemiology of AKI after major surgery using the latest Kidney Disease: Improving Global Outcomes (KDIGO) consensus definition of AKI. EPIS-AKI is an international prospective, observational, multicentre cohort study including 10 000 patients undergoing major surgery who are subsequently admitted to the ICU or a similar high dependency unit. The primary endpoint is the incidence of AKI within 72 hours after surgery according to the KDIGO criteria. Secondary endpoints include use of renal replacement therapy (RRT), mortality during ICU and hospital stay, length of ICU and hospital stay and major adverse kidney events (combined endpoint consisting of persistent renal dysfunction, RRT and mortality) at day 90. Further, we will evaluate preoperative and intraoperative risk factors affecting the incidence of postoperative AKI. In an add-on analysis, we will assess urinary biomarkers for early detection of AKI. EPIS-AKI has been approved by the leading Ethics Committee of the Medical Council North Rhine-Westphalia, of the Westphalian Wilhelms-University Münster and the corresponding Ethics Committee at each participating site. Results will be disseminated widely and published in peer-reviewed journals, presented at conferences and used to design further AKI-related trials. Trial registration number NCT04165369

Pneumoretroperitoneum and Perirenal Air Associated With Pneumothorax in an Extremely Low-Birth-Weight Infant

Pneumothorax-associated pneumoretroperitoneum and perirenal air have rarely been reported in infants. We report a case of an extremely low-birth-weight infant who developed pneumoretroperitoneum and perirenal air associated with tension pneumothorax and deteriorated acutely despite prompt pleural water-seal vacuum drainage system insertion. Our aim in presenting this case report is to emphasize keeping in mind that there could be extrapleural air leaks, such as pneumoretroperitoneum in patients with pneumothorax

Neu-Laxova syndrome in an appropriate for gestational age newborn

Neu-Laxova syndrome is a rare lethal congenital disorder involving multiple systems. Intrauterine growth retardation, ichthyosis, microcephaly, abnormal facial findings, and limb contractures are its key features. We present a case of Neu-Laxova syndrome in a male appropriate for gestational age (AGA) newborn with characteristic features including ichthyosis, microcephaly, severe ectropion, rudimentary ears, eclabion, limb contractures, and hypoplastic genitalia. The patient was born at 38 weeks of gestation to consanguinous Turkish parents. The mother was a 20-year-old primi gravida with lack of prenatal follow-up. Therefore, the case was diagnosed postnatally, and he died 5 days later. Because of the autosomal recessive inheritance of Neu-Laxova syndrome, in countries with high rates of consanguineous marriage, such as Turkey, physicians have to know this syndrome, and serial prenatal ultrasound examinations with genetic counseling should be performed on pregnant women at high risk. To the best of our knowledge, this is the first case described in an AGA newborn

Incidence and severity of retinopathy of prematurity in Turkey

Conclusions The findings of our study have the important implication that more mature babies are at risk of severe ROP requiring treatment. An effective programme for detecting and treating ROP should be established in Turkey

Predictive Values of Neutrophil CD64 Expression Compared with Interleukin-6 and C-Reactive Protein in Early Diagnosis of Neonatal Sepsis

Background Despite major advances in the management of newborn infants, neonatal sepsis (NS) remain important causes of neonatal morbidity and mortality in the newborn, mainly among preterm and low birth weight infants. Objective: The aim of this study was to investigate the usefulness of neutrophil CD64 expression alone and together with other infection markers in NS. Methods: Peripheral blood samples were taken from 109 neonates, who were categorized into three groups: proven or clinical sepsis (n = 35); disease without infection (n = 42); and healthy controls (n = 32). Complete blood count with differential, interleukin-6 (IL-6), C-reactive protein (CRP), and cell surface expression of CD64 on neutrophils have been evaluated in a prospective manner as a diagnostic aid for NS. Results: Expression of CD64 was significantly enhanced in neonates with sepsis compared with newborns with disease without infection and healthy controls (P = 0.001 and P = 0.001, respectively). Cutoff values of IL-6, CRP, CD64(MFI), and CD64(i) were 24.9 pg/ml, 4.05 mg/l, 87.7, and 4.39, respectively. Sensitivity-negative predictive values of IL-6, CRP, and CD64(MFI)/CD64(i) were 80.0-90.6%, 80.0-88.8%, and 88.6-94.0%, respectively. Combining all three tests increased the sensitivity to 100%; however, specificity and positive predictive value decreased to 62.1 and 55.5%, respectively. Conclusions: CD64 might be used either alone or combined with IL-6 and CRP for early diagnosis of NS. The advantages of CD64 when compared with IL-6 and CRP are rapid quantitation, very small blood volume required, and easy handling. J. Clin. Lab. Anal. 24:363-370, 2010. (C) 2010 Wiley-Liss, Inc

An Unusual Case of Heteropagus: Autosite With a Complex Cardiac Malformation

Asymmetrical form of conjoined twinning (heteropagus) is an extremely rare event with an incidence of 1–2 million live births. The incomplete component of heteropagus, namely, parasite, usually consists of rudimentary organs. Therefore, the autosite component of heteropagus can be separated successfully. A wide spectrum of associated congenital cardiac malformations, which are usually minor, has been described in autosites. However, a single-ventricle heart anomaly in the autosite has been reported in a very few cases. We report an unusual case of heteropagus with a complex cardiac malformation. To the best of our knowledge, this is the third heteropagus case in the literature with a single-ventricle heart in the autosite
