Peritoneal dialysis is a relatively safe and effective form of therapy for acute renal failure (ARF). As dextrose in the dialysate provides the osmotic gradient to achieve fluid removal, frequent exchanges with dialysate containing high dextrose is occasionally used to achieve negative balance in fluid overloaded patients. It has previously been shown that dextrose absorption from the peritoneal cavity is significant. Using indirect calorimetry and analyzing the dialysate effluent for its dextrose concentration, we studied the effects of high dextrose-containing dialysate in five patients with ARF. Despite minimal intake of calories, all patients had an RQ greater than 1.0 consistent with net lipogenesis resulting from dextrose absorbed from the peritoneal cavity. Four of five patients absorbed greater than 500 g of dextrose over 24 h. As overfeeding could lead to hepatic steatosis, increased CO2 production with worsening of respiratory failure, and hyperglycemia, the risks of using high dextrose-containing dialysate fluids should be weighed carefully against potential benefits. When nutritional support is indicated in such patients, contribution of dextrose calories from dialysate fluid should be taken into account.

All cases of human leptospirosis observed at the S. Bortolo Hospital, Vicenza, Italy, in the period from September 1990 to December 2003 were retrospectively reviewed. The aim of the study was to define the epidemiological, clinical, diagnostic, and therapeutic aspects of this infection and to compare these with an earlier local study (1979-1990) in order to assess if any changes have occurred over time. The screening test was made using macroscopic agglutination and the diagnosis was definitively confirmed using the microscopic agglutination test (MAT). The etiological serotype was identified in 13 patients (68%) and Leptospira poi was the most frequent serovar. Hepatic and renal involvements were present in a high percentage of patients (71% and 74%, respectively), cardiac involvement in 39%, and hypertriglyceridemia and hepatic steatosis were observed in 68% and 43% of cases, respectively. One patient died because of acute renal and respiratory failure. Intravenous penicillin was the treatment of choice. A consistent reduction in the prevalence was observed during the time period of this study (n = 38) compared with the previous period (n = 86); males were more affected than females in both time periods. In industrialized countries the prevalence of leptospirosis is decreasing; nevertheless, this infection is no longer limited to specific occupational groups and remains a potential fatal disease that should be included in the differential diagnosis of all the patients with unexplained fever.

Adult living donor liver transplantation (ALDLT) is an accepted procedure to overcome the organ shortage. The advantages of ALDLT must be balanced against the first concern of donor safety. We analyzed the results of our early experience among a series of eight ALDLT performed between April 2001 and October 2003. All patients were listed as United Network for Organ Sharing UNOS status 2b and 3. Transplant recipients consisted of four men and four women. The living donors included four sons, three daughters, and one son-in-law (ages 20 to 45 years). One donor was anti-HBc-positive and negative for hepatitis B virus-DNA by polymerase chain reaction analysis in serum and in liver tissue. GR/WR >0.8 and fatty liver <10% were considered suitable for the hepatectomy. Residual left lobe volume was at least 33%. No exogenous blood and blood products were transfused into the donors and a cell-saver device was used in all donors (blood loss 490 +/- 160 mL). All procedures were right lobe hepatectomy; in one case the middle hepatic vein was withdrawn with the right graft. The mean ischemia time was 1.5 +/- 0.5 hours. All donors survived the procedure. Median hospital stay was 8.5 +/- 2.1 days in all donors but one who had a long stay because of drug-related hepatitis. One graft was lost and one donor aborted because of preoperative overestimated volumetry. Complications were experienced by two donors (25%). Five recipients (62.5%) experienced major complications; one patient underwent retransplantation because of donor graft loss. Two biliary and two vascular complications (33.3%) occurred in three patients. No perioperative death occurred. Two patients died at 9 and 10 months after transplant because of heart and respiratory failure in the first case and tumor recurrence in the second. One-year actuarial survival is 75%. ALDLT using right lobe has gained acceptance to overcome the organ shortage. Donor selection criteria must be stringent with respect to residual donor hepatic volume, steatosis, and liver function.

Here we report a case of leptospirosis without fever during the late stage of pregnancy in which the initial clinical presentation was more suggestive of a pregnancy-related liver dysfunction rather than an infectious disease. A 32-year-old primipara at 37 week of gestation was hospitalised with a 10-day history of nausea, vomiting, and abdominal pain without fever. Initial routine blood tests showed hyperbilirubinemia, a moderate increase in transaminase levels, severe coagulopathy and an increased creatinine level. On clinical suspicion of pregnancy-related liver dysfunction such as HELLP syndrome (hemolysis, elevated liver enzyme levels, low platelet count) or acute fatty liver of pregnancy (AFLP), emergency caesarean section was performed and a healthy baby was delivered. Postoperatively, the patient was stable, but 5 days later she developed clouding of consciousness, severe jaundice and respiratory failure. At this time, an infectious disease was considered and leptospirosis was confirmed by serological tests. In conjunction with intensive care management, antibiotic therapy was given; the patient was discharged in good condition and her baby did not develop signs of active leptospirosis. While leptospirosis is rare in pregnancy, this is the first report of acute infection without fever mimicking the clinical pattern of HELLP syndrome or AFLP

A 54-year-old man was admitted to hospital after being found unconscious in his home. He had a history of alcoholism, multiple drug addictions, and type I diabetes mellitus. At admission, he had hyperglycaemia (550 mg/dL) with glucosuria and ketone bodies in the urine, along with septic shock refractory to bilateral alveolar infiltrates and severe respiratory failure. The patient died 24 hours post admission due to multiple organ failure, with diabetic ketoacidosis decompensated by possible respiratory infection in a patient with polytoxicomania. The autopsy confirmed the presence of acute bilateral bronchopneumonia, chronic pancreatitis, severe hepatic steatosis, and generalized congestive changes. At the oesophagus, acute oesophageal necrosis was evident.

Propofol is an intravenous short-acting anesthetic widely used to induce and maintain general anesthesia and to provide procedural sedation. The potential for propofol dependency and abuse has been recognized, and several cases of accidental overdose and suicide have emerged, mostly among the health professionals. Different studies have demonstrated an unpredictable interindividual variability of propofol pharmacokinetics and pharmacodynamics with forensic and clinical adverse relevant outcomes (e.g., pronounced respiratory and cardiac depression), namely, due to polymorphisms in the UDP-glucuronosyltransferase and cytochrome P450 isoforms and drugs administered concurrently. In this work the pharmacokinetics of propofol and fospropofol with particular focus on metabolic pathways is fully reviewed. It is concluded that knowing the metabolism of propofol may lead to the development of new clues to help further toxicological and clinical interpretations and to reduce serious adverse reactions such as respiratory failure, metabolic acidosis, rhabdomyolysis, cardiac bradyarrhythmias, hypotension and myocardial failure, anaphylaxis, hypertriglyceridemia, renal failure, hepatomegaly, hepatic steatosis, acute pancreatitis, abuse, and death. Particularly, further studies aiming to characterize polymorphic enzymes involved in the metabolic pathway, the development of additional routine forensic toxicological analysis, and the relatively new field of ''omics" technology, namely, metabolomics, can offer more in explaining the unpredictable interindividual variability.

Fat embolism is markedly underdiagnosed, even though it is a well-known phenomenon following fractures of the long bones, injury to subcutaneous fat tissue, rupture of a fatty liver, surgical operations on fatty tissues, septicemia, burns and barotrauma. Forensic pathologists tend to "simplify" autopsy report conclusion in cases with multiple injuries where fat embolism and exsanguination could be considered to be the concomitant causes of death. Herein we present a case of 24-year-old male who was beaten with a metal rod by several persons. On admission to hospital his vital signs and laboratory findings indicated hemorrhagic shock with gradual respiratory failure; he died 17 h after injury. On internal autopsy examination the subcutaneous tissue of the limbs and back was severely bruised, corresponding to about 35% of the body surface area. He had fractures of several small bones. Injuries of the internal organs were absent, there was no free blood in the body cavities, and all other autopsy findings were unremarkable but suggestive of a significant blood loss. Microscopic examination showed a massive pulmonary fat embolism (grade III according to Sevitt), without systemic fat embolism. The cause of death was attributed to pulmonary fat embolism combined with severe blood loss, following extensive and severe bruising of the subcutaneous tissues and bone fractures.

A 49-year-old lady with no past medical history presented with dysphagia and 40-pound weight loss, which occurred over eight months. On physical examination, she had proximal muscle weakness and crackles in basilar regions of the lungs. Labs were significant for low albumin, elevated transaminases, and high aldolase. Imaging suggested aspiration pneumonitis in both lungs and hepatic steatosis. A swallow evaluation revealed oropharyngeal dysphagia and muscle biopsy confirmed a rare form of myositis. A liver biopsy showed steatohepatitis and a diagnosis of starvation-induced steatohepatitis was made. The patient succumbed to hypoxic respiratory failure from aspiration pneumonitis before the treatment for myositis could be initiated. We report the first case of starvation-induced steatohepatitis in a patient with dysphagia from myositis affecting the oropharyngeal musculature.

Aspergillus molds are ubiquitous environmental molds that can cause devastating invasive infections in immunocompromised patients. These infections often go unrecognized in critically ill patients. This case describes a 68 year-old female resident of a long-term nursing facility with history of dementia, nonalcoholic fatty liver disease with cirrhosis, chronic kidney disease stage III and insulin-dependent type 2 diabetes who presented with vomiting, diarrhea and leg swelling. She developed hypotension and was treated for sepsis but found to have negative routine infectious workup. Chest imaging showed nodular densities and bilateral opacities. She developed acute renal failure and hypoxic respiratory failure followed by acute decompensated cirrhosis with refractory volume overload and hypotension and was eventually transitioned to comfort care measures. Autopsy ultimately showed invasive pulmonary aspergillosis. Here we review the diagnosis and management of invasive fungal infections in critically ill patients without typical risk factors or clinical findings for invasive fungal disease. Invasive fungal infections are frequently missed and carry high mortality rates, therefore warranting consideration in critically ill populations.

In deceased donor liver transplantation, a donor liver with moderate (>30%) macrosteatosis used to be considered inappropriate for grafting. We examined the outcomes of children who underwent living donor liver transplantation (LDLT) at the National Center for Child Health and Development whose donor livers had moderate-to-severe macrosteatosis. Twelve children were enrolled who had received a moderate-to-severe macrosteatotic liver graft and underwent liver biopsy soon after LDLT. The primary diseases were biliary atresia in 7 patients, acute liver failure in 3 patients, glycogen storage disease type 1 in 1 patient, and primary sclerosing cholangitis in 1 patient. Median age was 11 months. There were 4 recipients who received grafts from their fathers, and 8 received grafts from their mothers. Median donor age was 35.5 years. We compared the degree of donor liver steatosis with the results of graft liver biopsies that were collected 4-105 days after LDLT. The levels of donor liver macrovesicular steatosis were moderate (34%-66%) in 9 patients and severe (>66%) in 3 patients. The nonalcoholic fatty liver disease activity score was 3 in 7 patients and 4 in 5 patients. Shortly after LDLT, 11 of 12 patients showed improvement in steatosis compared with the donor livers. One biopsy specimen taken 22 days after LDLT showed 60% macrosteatosis, which was the same as that in the donor liver. However, this patient was alive and well 6 years after LDLT. One patient died after LDLT because of infection and respiratory failure. The levels of steatosis of the donor liver grafts improved soon after LDLT in children, and the outcomes of children receiving a moderate-to-severe macrosteatotic liver from their parents were excellent.
