Ischemic hepatitis is an uncommon cardiovascular surgery complication. Hepatic biopsies show centrolobulillar necrosis. The term "hepatitis" was proposed because of a raise in hepatic enzymes similar with infectious disease, and "ischemic" because of failure in hepatic perfusion. Ischemic hepatitis was then defined as an acute and reversible elevation of hepatic enzymes (within 72 h), associated with disturbance in hepatic perfusion after excluding other causes of acute hepatitis. A 53 year-old male presented complaining of a 12 h epigastric pain, without nausea or vomiting, resistant to medication. He underwent an aortic valve replacement and was under anticoagulation. He suddenly developed shock and multiorgan failure. Jaundice and cardiac tamponade signs were present, associated with elevated hepatic enzymes. A transthoracic echocardiography accounted for cardiac tamponade signs. A pericardiocentesis was performed, removing 970 cc of hemorrhagic fluid, and hemodialysis, with improvement of his hemodynamic status. Hepatic enzymes improved. Viral markers were negative.

To determine the safety of a combination of mycophenolate mofetil (Cellcept, MMF) and IFNbeta-1a (Avonex) in relapsing-remitting multiple sclerosis (RRMS) and to evaluate the effects of the combination on clinical and magnetic resonance imaging (MRI) measures of disease activity. Secondary objectives were clinical and MRI data. An open-label, single-centre study including 30 RRMS patients was performed. Inclusion criteria were patients expanded disability status scale (EDSS) score <6.0, treated by Avonex for at least 6 months, with at least two relapses during the previous 2 years and at least one during the previous 6 months. MMF at a progressive dose of 2 g per day orally was added to Avonex for a duration of 6 months. MRI data were obtained at baseline and at the end of the study. The pre-study annual relapse rate was 2.0 +/- 0.7 and the EDSS score at baseline was 2.9 +/- 1.3. Eleven patients had gadolinium (Gd)-enhanced lesions at baseline for a total number of 35 lesions. Two patients interrupted the combination, one after the first dose for personal reasons unrelated to the study and the other due to diarrhoea. A few of the patients also reported nausea and abdominal pains. Adverse events included benign infectious diseases, insomnia and dizziness. No significant biological abnormalities were noted. The annualized relapse rate was 0.57 +/- 0.3 at the end of the study (P < 0.001). The mean EDSS score was 2.6 +/- 1.5 and no Gd-enhanced lesions were detected on MRI at the end of the study. MMF and IFNbeta-1a (Avonex) combined therapy is safe and very well-tolerated. Clinical and MRI data suggest that this combination may be beneficial.

Currently, randomized phase III trials have demonstrated that docetaxel is an effective strategy in the adjuvant treatment of breast cancer. However, previous attempts to incorporate docetaxel with an anthracycline in a dose-dense regimen have been unsuccessful. Therefore, new schedules containing both drugs should be explored. Forty-four patients with high-risk operable breast cancer entered this feasibility study. They were treated with three cycles of epirubicin 110 mg/m2 every 2 wk with G-CSF followed by three cycles of "intensified" CMF (840 mg/m2 cyclophosphamide; 57 mg/m2 methotrexate; 840 mg/m2 fluorouracil) every 2 wk with G-CSF followed 3 wk later by nine weekly cycles of 35 mg/m2 docetaxel (E-CMF-doc). Totally, 39 patients (89%) received all cycles of chemotherapy. The vast majority (92%) of cycles were administered at full dose. Therefore, dose intensity was sufficiently maintained for all drugs. Toxicity was generally mild to moderate. Most frequently recorded side effects apart from alopecia were neutropenia (54%) and nausea/vomiting (89%). Infection developed in nine patients. Two cases of febrile neutropenia were reported. The E-CMF-doc regimen, as used in this study, is feasible and well tolerated. Its impact on survival should be evaluated in phase III trials.

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

Deliberate hyperthermia has been used clinically as experimental therapy for neoplastic and infectious diseases. Several case fatalities have occurred with this form of treatment, but most were attributable to systemic complications rather than central nervous system toxicity. Nonetheless, demyelating peripheral neuropathy and neurological symptoms of nausea, delirium, apathy, stupor, and coma have been reported. Temperatures exceeding 40 degrees C cause transient vasoparalysis in humans, resulting in cerebral metabolic uncoupling and loss of pressure-flow autoregulation. These findings may be related to the development of brain edema, intracerebral hemorrhage, and intracranial hypertension observed after prolonged therapeutic hyperthermia. Furthermore, deliberate hyperthermia critically worsens the extent of histopathological damage in animal models of traumatic, ischemic, and hypoxic brain injury. However, it is unknown whether these findings translate to episodes of spontaneous fever in neurologically injured patients. In a clinical setting fever is a strong prognostic marker of a patient's primary degree of neuronal damage, and a causal relation with long-term functional neurological outcome has not been established for most types of brain injury. Furthermore, in the neurosurgical intensive-care unit fever is extremely common whereas antipyretic therapy is only poorly effective. Therefore maintaining strict normothermia may be an impossible goal in many patients. Although there are several physiological arguments for avoiding exogenous hyperthermia in neurologically injured patients, there is no evidence that aggressive attempts at controlling spontaneous fever can improve clinical outcome.

The recent unfortunate rabies transmissions through solid organ transplants of an infected donor in Germany required the initiation of a vaccination program to protect health care workers (HCWs) with close contact to rabies-infected patients. A systematic follow-up of adverse effects was initiated. Rabies postexposure prophylaxis (PEP) was started in 269 HCWs at four German hospitals. Pre-exposure prophylaxis (PreEP) was administered to 74 HCWs caring for an already diagnosed rabies patient. At each vaccination date, HCWs were interviewed for symptoms possibly representing adverse effects. Adverse effects of PEP and PrePEP were compared. Out of 269 HCWs, 216 were included for the investigation of adverse effects. Of these 216 HCWs, 114 (53%) individuals developed at least one systemic adverse effect. Incidences of tiredness (30.6%), malaise (26.4%), headache (26.9%), dizziness (14.8%), and chills (13.0%) declined in the course of PEP (p < 0.05), whereas incidences of fever (7.4%), paraesthesias (7.9%), arthralgias (1.9%), myalgias (4.2%), nausea (9.3%), diarrheas (2.8%) and vomiting (1.4%) did not. In 11 (5.1%) HCWs PEP was discontinued mostly due to adverse reactions (four suffered strong headaches, two HCWs meningeal irritations, two chills, one paraesthesia, one malaise, and one a rush). Systemic effects of PEP or PreEP did not differ significantly. Despite relatively high incidences of moderate severe adverse reactions rabies PEP is safe. Strong headache, tiredness, dizziness, and paraesthesias are the most important postvaccinal symptoms. Vaccinees suffering from adverse effects of PEP must be strongly encouraged to complete PEP, as it is to date the only protection against fatal rabies.

Cannabis sativa L. is possibly one of the oldest plants cultivated by man, but has remained a source of controversy throughout its history. Whether pariah or panacea, this most versatile botanical has provided a mirror to medicine and has pointed the way in the last two decades toward a host of medical challenges from analgesia to weight loss through the discovery of its myriad biochemical attributes and the endocannabinoid system wherein many of its components operate. This study surveys the history of cannabis, its genetics and preparations. A review of cannabis usage in Ancient Egypt will serve as an archetype, while examining first mentions from various Old World cultures and their pertinence for contemporary scientific investigation. Cannabis historians of the past have provided promising clues to potential treatments for a wide array of currently puzzling medical syndromes including chronic pain, spasticity, cancer, seizure disorders, nausea, anorexia, and infectious disease that remain challenges for 21st century medicine. Information gleaned from the history of cannabis administration in its various forms may provide useful points of departure for research into novel delivery techniques and standardization of cannabis-based medicines that will allow their prescription for treatment of these intractable medical conditions.

Invasive pulmonary aspergillosis (IPA) poses major management problems for clinicians caring for patients with haematological diseases. The clinical courses of patients with IPA who had been hospitalised in Hematology Unit, Bone Marrow Transplantation Unit and Infectious Diseases and Clinical Microbiology Unit between 1998 and 2005, the efficacy and adverse effects and costs of antifungal drugs (conventional amphotericin B deoxycholate, liposomal amphotericin B, amphotericin B lipid complex and caspofungin) used in the therapy of these patients were analysed in this study. Ninety-three patients with IPA were reviewed retrospectively. Mean age of the patients was 40.4 +/- 15.1 years (range 14-70 years). Fifty-eight male patients and 35 female patients were included in the study. Manageable hypopotassemia, nausea/vomiting and headache were the most commonly observed side-effects during antifungal (AF) therapy. While it was not found to be statistically significant with regard to the mean time to resolution of fever (P = 0.8), it was found to be statistically significant with regard to radiological regression at 30th day, and mean duration of therapy between patients who were dead or alive (P < 0.05, P < 0.001). Total cost of AF therapy for 93 patients was found to be US$4 461 824 (minimum US$387-maximum US$279 023). Of this amount, US$4 272 845 represents the payment for AF drugs, US$188 979 the payment for other expenditures. Mean cost of therapy for a patient with IPA was found to be US$49 336. Although it seemed to be difficult, investigations should primarily focus on providing standardisation of parameters relating to the duration of AF therapy. Despite the less-than-optimal safety profile of CAB, it often remains to be the preferred first line option for the treatment of fungal infections because of its broad spectrum, activity and low acquisition cost.

Chikungunya virus (CHIKV) is an emerging arbovirus and is an important human pathogen. Infection of humans by CHIKV can cause a syndrome characterized by fever, headache, rash, nausea, vomiting, myalgia, arthralgia and occasionally neurological manifestations such as acute limb weakness. It is also associated with a fatal haemorrhagic condition. CHIKV is geographically distributed from Africa through Southeast Asia and South America, and its transmission to humans is mainly through the Aedes aegypti species mosquitoes. The frequency of recent epidemics in the Indian Ocean and La Reunion islands suggests that a new vector perhaps is carrying the virus, as A. aegypti are not found there. In fact, a relative the Asian tiger mosquito, Aedes albopictus, may be the culprit which has raised concerns in the world health community regarding the potential for a CHIK virus pandemic. Accordingly steps should be taken to develop methods for the control of CHIKV. Unfortunately, currently there is no specific treatment for Chikungunya virus and there is no vaccine currently available. Here we present data of a novel consensus-based approach to vaccine design for CHIKV, employing a DNA vaccine strategy. The vaccine cassette was designed based on CHIKV capsid- and envelope-specific consensus sequences with several modifications, including codon optimization, RNA optimization, the addition of a Kozak sequence, and a substituted immunoglobulin E leader sequence. The expression of capsid, envelope E1 and E1 was evaluated using T7-coupled transcription/translation and immunoblot analysis. A recently developed, adaptive constant-current electroporation technique was used to immunize C57BL/6 mice with an intramuscular injection of plasmid coding for the CHIK-Capsid, E1 and E2. Analysis of cellular immune responses, including epitope mapping, demonstrates that electroporation of these constructs induces both potent and broad cellular immunity. In addition, antibody ELISAs demonstrate that these synthetic immunogens are capable of inducing high titer antibodies capable of recognizing native antigen. Taken together, these data support further study of the use of consensus CHIK antigens in a potential vaccine cocktail.

Cefetamet pivoxil is an oral, third-generation cephalosporin whose broad spectrum of antibacterial activity and favorable pharmacokinetic profile make it particularly suitable for the treatment of a wide range of infectious diseases. Cefetamet has high in vitro activity against both gram-positive and gram-negative bacteria that cause a number of respiratory tract and urinary tract infections. These include penicillin-sensitive Streptococcus pneumoniae, Streptococcus spp, Haemophilus influenzae, Moraxella catarrhalis, Escherichia coli, Proteus spp., Klebsiella spp. and Neisseria gonorrhoeae. It is not active against staphylococci, enterococci, Pseudomonas spp. or Bacteroides fragilis but does inhibit most bile-sensitive (oral) Bacteroides spp. Animal toxicology studies indicate that neither cefetamet pivoxil nor the active compound cefetamet have significant teratogenic, mutagenic, photogenic or allergenic potential. Cefetamet is eliminated unchanged in the urine with a half-life of 2.2 h. Volume of distribution approximates the extracellular fluid space (0.3 1/kg), protein binding is minima (22%) and oral bioavailability of cefetamet pivoxil is approximately 50% when taken with food. No significant drug interactions have been noted to date. The efficacy and tolerability of cefetamet pivoxil have been evaluated in the treatment of gram-positive and gram-negative infections in almost 5,000 patients. In comparative studies, cefetamet pivoxil was at least as effective, and in many cases clinically superior, to most currently recommended antibiotics for the treatment of urinary tract infections including gonorrhea and complicated infections in high risk patients. Efficacy has also been demonstrated in acute exacerbations of chronic bronchitis, pneumonia and infections of the ear, nose and throat. Clinical trials have shown that a 7 day treatment period with cefetamet pivoxil is as effective as a 10 day course of phenoxymethylpenicillin in the treatment of pharyngotonsillitis. Cefetamet pivoxil has been well-tolerated in clinical trials with only 1.2% of patients on standard doses discontinuing therapy prematurely. The most common adverse effects are gastrointestinal (diarrhea, nausea, vomiting) which occur in less than 10% of patients. Many current antibiotic treatment regimens involve the administration of three or more daily doses. However, standard doses of cefetamet pivoxil 500 mg twice daily provide unbound plasma concentrations of cefetamet which generally exceed the MIC(90) for susceptible organisms throughout the dosing interval and have been demonstrated to be clinically effective. This should result in good compliance with therapy in out-patients. Dosing regimens for cefetamet pivoxil should be adjusted in patients with impaired renal function while standard doses can be given to elderly patients and those with liver disease. Standard doses in children are 10 mg/kg or alternatively, children may receive a dose reduced in proportion to the ratio of their body surface area to that of an adult.
