Acute fatty liver of pregnancy - A short review.

Acute fatty liver of pregnancy (AFLP) is a rare but dramatic condition associated with a high maternal and fetal morbidity and mortality. We present a short review of AFLP management, illustrated by a case report. We conducted a systematic literature search for 'acute fatty liver of pregnancy', concerning its management. We found initially 11 studies, and three of them met the selection criteria. Prompt diagnosis, maternal stabilisation and rapid delivery are mandatory. This illustrative AFLP case fulfilled nine out of 14 Swansea criteria. Caesarean section is often required (as illustrated in this case), reducing maternal and perinatal mortality rates.

Anesthetic Management of a Voluminous Left Atrial Myxoma Resection in a 19 Weeks Pregnant with Atypical Clinical Presentation.

We report the case of a semi-urgent cardiac surgery, in a 19 gestation age pregnant. Despite the fact that the patient was asymptomatic, except for some palpitations, a large left auricle (LA) myxoma was fortuitously diagnosed with transthoracic echocardiography (TEE). Considering the important embolic risk, the tumor was successfully removed during cardiac surgery under cardiopulmonary bypass (CPB). Fetal bradycardia following defibrillation under stable maternal and CPB conditions was successfully managed. The postoperative period and remainder of the pregnancy was smooth and the delivery uneventful.

Immune responses in relation to the type and time of thermal injury: an experimental study.

BACKGROUND: Thermal injuries are followed by a complex immune response, but the relationship between the severity of burn injury and the time exposure to the thermal injury on the extent of the immune response is still not known. OBJECTIVE: This study focuses on characterising the effect of temperature and time exposure on the post-burn immune response. METHODS: We used 120 C57BL/6 male mice divided equally in 5 burn groups and one sham operated group (groups A-E and sham). Ten mice per group were sacrificed at 24 and 48 h after burn injury and whole blood was collected; specimens of liver, lung, spleen, kidney and bowel were excised. Apoptosis and TREM-1 expression on circulating blood cells were measured. Splenocytes were isolated and stimulated for cytokine production; the rate of apoptosis of splenocytes was also measured. RESULTS: Production of IL-17 from splenocytes of mice group D was enhanced. Considerable effects were shown on the apoptosis of circulating lymphocytes and of spleen cells. The apoptotic rates varied between groups and also evolved after 24 and 48 h. To examine the origin of this differential response, quantitative bacterial cultures of liver, lung and kidney were made but no differences were observed compared with sham-operated animals. LIMITATIONS: This study was based on an experimental murine model. CONCLUSION: There is a unique response for each type of injury depending on the temperature of the thermal source and the exposure time.

Bacterial translocation in an experimental model of multiple organ dysfunctions.

BACKGROUND: In order to investigate the hypothesis that bacterial translocation from the intestine contributes to death after multiple organ dysfunction syndrome (MODS), a sterile MODS model was studied. METHODS: MODS was induced in 139 male C57BL/6 mice by lipopolysaccharide (LPS) (endotoxin) infusion followed by zymozan infusion in four groups: Α, sham-operation; Β, LPS; C, LPS + 0.8 g/kg zymozan; and D, LPS + 1.2 g/kg zymozan. Mice were sacrificed at 24 and 48 h for quantitative tissue cultures, isolation, and stimulation of splenocytes, measurement of apoptosis of lymphocytes and macrophages, and of serum LPS and survival. Some mice with MODS were treated with the antibiotic ertapenem. RESULTS: Enterobacteriaceae and Enterococcus spp were isolated from tissues. Group D had the highest bacterial load and the shortest survival. Release of interleukin-10, of interleukin-17, and of intgerferon-γ by splenocytes and the rate of apoptosis did not concur with immune paralysis. Serum LPS concentrations were higher in mice with MODS versus controls. Ertapenem prolonged survival and decreased the bacterial load. CONCLUSIONS: Bacterial translocation seems to be an important contributor leading from MODS to death and suggests a change in therapy towards adaptation of antimicrobial treatment upon early signs of MODS.
