Cold agglutinins are autoantibodies that agglutinate red blood cells at low temperatures, leading to haemagglutination and haemolysis. They are generally of no clinical significance. However, when people with cold agglutinins undergo cardiac operation with hypothermia and cold cardioplegia, they can experience complications. Thus, different perioperative management is required for such patients. We describe a 74-year-old man with cold agglutinins incidentally detected on the preoperative screening test. He had never experienced any complications or developed a haematological disease...

The neonatal brain is extremely vulnerable to injury during periods of hypoxia and/or ischemia. Risk of brain injury is increased during neonatal cardiac surgery, where pre-existing hemodynamic instability and metabolic abnormalities are combined with long periods of low cerebral blood flow and/or circulatory arrest. Our understanding of events associated with cerebral hypoxia-ischemia during cardiopulmonary bypass (CPB) remains limited, largely due to inadequate tools to quantify cerebral oxygen delivery and consumption non-invasively and in real-time...

REVIEW
Erik Sveberg Dietrichs, Georg Sager, Torkjel Tveita
Rewarming from accidental hypothermia is often complicated by hypothermia-induced cardiac dysfunction, calling for immediate pharmacologic intervention. Studies show that although cardiac pharmacologic support is applied when rewarming these patients, a lack of updated treatment recommendations exist. Mainly due to lack of clinical and experimental data, neither of the international guidelines includes information about pharmacologic cardiac support at temperatures below 30 °C. However, core temperature of accidental hypothermia patients is often reduced below 30 °C...

OBJECTIVE: Through the application of eustachian tuboplasty assisted with hypothermy plasma ablation, we evaluate its efficacy in the threatment of adult refractory otitis media with effusion. METHOD: We retrospectively reviewed the charts of 48 cases (61 ears) suffering from adult refractory otitis media with effusion from January 2012 to December 2013. According to the admission date, the patients were divided into the control group (17 cases, 22 ears) and the treatment group (31 cases, 39 ears)...

INTRODUCTION: Traditionally, tumor thrombi extending into the right atrium have been managed by open surgery with sternotomy, cardiopulmonary bypass circulation and hypothermic circulatory arrest, and are associated with significant morbidity and mortality rates. Here, we evaluate the results of cavoatrial thrombectomy using our own, Foley catheter assisted-technique, obviating the need for thoracotomy, extracorporeal circulation, and/or hypothermic circulatory arrest. MATERIAL AND METHODS: Between June 2013 and January 2015, 4 consecutive patients underwent cavoatrial thrombectomy performed with our own, Foley catheter assisted technique, via Chevron incision, with no need for extracorporeal circulation or hypothermy for renal cell carcinoma with tumor thrombus extending into the right atrium...

BACKGROUND: Stroke is the third leading cause of death. Hypothermia has been recognized as an effective method in reducing brain injury. In this study, we assessed the effects of granulocyte colony-stimulating factor (G-CSF) as a neuroprotective agent and mild hypothermia on mortality, behavioral function, infarct volume, and brain edema in Wistar rats. METHODS: Forty male rats were used in five groups (eight rats in each group): control, hypothermy, G-CSF, combination hypothermy + CSF, and sham...

This is a prospective study of patients treated at the Center for Urgent Surgery, Clinical Center of Serbia. The patients were divided into two groups; i.e., the controls consisted of 30 subjects, who underwent conventional cholecystectomy, and studied group with 30 patients who had laparoscopic cholecystectomy. The patients were homogenized by ASA score (ASA I and ASA II) and on population basis. Hemodynamic parameters and 4 time-point pulmonary function tests were monitored in both groups. Peritoneal insufflation resulted in significant increase of systemic arterial pressure (23%), mean arterial pressure (23...

Pectin, a polysaccharide extracted from the cell wall of plants, was used as the drug carrier to synthesize the pectin-adriamycin conjugates (P(A)n). The structure of the conjugates was confirmed by UV and IR. The degree of esterification (DE) of the pectin was assessed, and it was found that DE significantly influenced the carboxy group contents, inherent viscosity and galacturonic acid contents of the pectin. The results of drug release test in vitro showed that the conjugate was stable in normal saline, but was gradually enzymolyzed to release the adriamycin in blood plasma and in lymph nodes...

Abstract The hypothalamic somatostatinergic system was devitalized in male rats by intracerebroventricular (icv) cysteamine (CSH) pretreatment (250 mug/rat/day into the third ventricle) on 4 consecutive days or by a limited lesion of the hypothalamic periventricular nucleus (PeVNx). The acute effect of icv serotonin (5-HT) on the cold-stimulated thyrotropin (TSH) and prolactin responses were studied in these animals. The experiments were performed 24 h after the last saline or CSH infusions and 7 days after the sham- or PeVN-lesions...

OBJECTIVE: To investigate the role of gap-junction in suspended animation for hemorrhagic shock with brain injury. METHODS: Twenty-four SD rats were made into models of uncontrolled hemorrhagic shock and occlusion of bilateral common carotid arteries and randomly divided into 3 equal groups: traditional resuscitation group (Group I) undergoing traditional resuscitation, hypothermy resuscitation group (Group II) undergoing temperature lowering by ice-cap, and carbenoxolone resuscitation group (Group III) undergoing injection of carbenoxolone 50 microg/200 g...

OBJECTIVE: We present our 20 years experience treating patients with vena cava extension in whom an extracorporeal circulation, hypothermia, cardio circulatory arrest (ECC-H-CCA) in order to perform, together with a tumoral resection, a thrombus resection. MATERIAL AND METHODS: From 1985 to 2005 a total of 28 retroperitoneal tumor were treated: 25 renal cancers, a Wilms tumor, a paratesticular rabdomiosarcoma, and a pheocromocitoma. All of them had an extension by means of thrombus above the suprahepatics veins...

Since biological functions of the elements are generally different, depending on their chemical forms, chemical speciation analysis is really important in metallomics research. Thus, multielement analysis and chemical speciation of the elements in serum were carried out in the present work. A hyphenated technique was developed for high-throughput speciation analysis of the copper, iron and zinc in serum by molecular biology technology and flame atomic absorption spectrophotometry (AAS). Here, Cu, Fe and Zn in serum were classifyied as the forms of combination and non-combination...

REVIEW
Hailei Wu, Jinliang Zhang
Varieties of air temperature and solar activity have a close correlation with human health. The megatemperature mainly results in the increased incidence of cerebrovascular disorder (CVD). It is related to the regulatory mechanism of homeothermism. In the hypothermy environment, obvious increment of human's blood viscosity was observed, which may induce the cerebral infarction, myocardial infarct or coronary heart disease. Not only have solar activities a close relationship with the incidences of plague and epidemic cerebrospinal meningitis, but also high correlation with onco-genesis and infant natality and mortality...

A brief history of the Tissue Bank (TB) of the University Hospital Hradec Králové, Czech Republic, established by Dr. R. Klen in 1952 is presented. In Dr. Klen's original concept the TB was defined as a department specialised in the harvesting, processing, preservation, storage and distribution of various kinds of tissue for clinical and experimental practice. The first kinds of tissue collected in cadaveric donors were corneas, bone and skin. Xenogeneic cartilage and bone grafts were prepared at the same time...

Anis Baraka
There are two different strategies of acid-base regulation during hypothermis. The alpha-stat strategy of ectotherms maintains the temperature-uncorrected arterial PCO2 and pH at normothermic values (i.e., 40 mmHg and 7.4, respectively), irrespective of the body temperature. In contrast, the pH-stat of hibernators maintains the temperature-corrected pH and PCO2 at the normal values at the different body temperatures. Clinically, it appears that it is more physiological to use the alpha-stat strategy whenever tepid or moderate hypothermic CPB is used in order to maintain intracellular electrochemical neutrality, and to adopt the pH-stat strategy whenever deep hypothermic circulatory arrest is induced, in order to otimize brain protection...
