This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to intraoperative and postoperative complications, and time to discharge from hospital for knee arthroscopies in outpatients. We studied 70 ASA I patients scheduled for elective outpatient knee arthroscopy. The patients were randomly allocated into two groups to receive either 3 ml (15 mg) 0.5% hyperbaric bupivacaine (bilateral group) or 1.5 ml (7.5 mg) 0.5% hyperbaric bupivacaine (unilateral group). The duration of motor and sensory block and the time to discharge from the hospital were all recorded. Perioperative complications such as hypotension, bradycardia, nausea, vomiting, urinary retention, if present, were recorded. The patients were interviewed by telephone 7 days later, and each patient was asked about headache or backache. The duration of motor and sensory block, and the time to discharge from hospital was shorter in the unilateral group than in the bilateral group. Three patients in the bilateral group were treated for hypotension. Bradycardia occurred in two patients in the bilateral group, and three patients required temporary bladder catheterization due to delay in recovery of spontaneous urination. Nausea and vomiting occurred in three patients in bilateral group. Nine patients in the bilateral group and six patients in the unilateral group developed postspinal headache. Backache occurred in five patients in the bilateral group and in six patients in the unilateral group. Our data indicate that the use of unilateral spinal block is a suitable technique for knee arthroscopies in outpatients.

The authors present the case reports of a 30-year-old man and his 29-year-old wife who ingested a mushroom meal containing Cortinarius speciosissimus. Features of this intoxication include gastrointestinal symptoms such as nausea, vomiting, and diarrhea as well as back pain. The toxin orellanine is nephrotoxic and can lead to acute renal failure. A long symptom-free interval of 2 to 21 days is characteristic of this poisoning. The diagnosis can be made by mycologic testing or by toxicologic analysis of a renal biopsy specimen. Reported therapeutic options include hemodialysis, plasmapheresis, or drug therapy with corticosteroids, all of which have yielded variable results. Here the authors report the use of antioxidant therapy in 2 patients with acute renal failure caused by Cortinarius speciosissimus intoxication.

In observational cohort studies which monitor drug safety, the patterns of reported events are likely to be influenced by a number of factors. We hypothesized that the distribution of events which are unlikely to be adverse events associated with drug use, differ from that for events which may be adverse drug reactions. In 39 individual Prescription-Event Monitoring (PEM) studies, the incidence rates for upper respiratory tract infections (URTI) and back pain, in the first month of treatment and in the subsequent 5 months, were compared to those for nausea/vomiting and malaise/lassitude. For URTI and back pain there was no statistically significant difference in the event rates between these time periods. This pattern may be characteristic of events which are independent of the disease being treated and are unlikely to be adverse events associated with drug use. However, for nausea/vomiting and malaise/lassitude, which can be adverse events associated with drug treatments, the event rates in the first month of treatment were significantly greater than in subsequent months. These observations confirm that doctors are reporting events irrespective of whether or not they suspect the event to be an adverse event associated with the drug. This provides a simple validation of the PEM methodology.

BACKGROUND: Depression is underdiagnosed in the primary care setting. Physical symptoms such as aches, pains, and gastrointestinal disturbance are frequently associated with major depressive disorder (MDD) and are often the presenting symptoms. Duloxetine, a dual-reuptake inhibitor of serotonin and norepinephrine, may have a positive effect on physical symptoms in addition to efficacy in treating emotional symptoms of depression. METHOD: Efficacy was evaluated in 6 double-blind, placebo- and/or active comparator-controlled trials of duloxetine for patients with MDD (DSM-IV criteria). Efficacy in depression was determined primarily using the 17-item Hamilton Rating Scale for Depression (HAM-D-17). Secondary efficacy measures included subscales of the HAM-D-17 and assessment of physical symptoms. Safety evaluations included adverse events, vital signs, laboratory analyses, and electrocardiograms. Safety was evaluated by pooling the data from the MDD trials and a study of duloxetine in nondepressed patients. RESULTS: Duloxetine demonstrated significant differences from placebo on core mood symptoms, physical symptoms (e.g., back pain), and global functioning as early as week 1 of treatment. The estimated probabilities of remission in the studies that demonstrated efficacy ranged from 43% to 57%. The most frequently observed adverse events for duloxetine-treated patients included nausea, dizziness, insomnia, fatigue, and somnolence. Duloxetine did not prolong corrected QT intervals, and the rate of sustained elevations of blood pressure did not differ significantly from placebo. CONCLUSION: In these studies, duloxetine was safe and effective in the treatment of both emotional and physical symptoms of MDD. Based on dose assessments, 60 mg q.d. appears to be the optimum starting and therapeutic dose.

Intravenous immunoglobulins (IVIgs) exert a variety of immunomodulating activities and are, therefore, increasingly being used for the treatment of immune-mediated as well as autoimmune diseases. There is also accumulating evidence that high-dose IVIg (hdIVIg) is highly efficacious in the treatment of skin diseases, despite the lack of evidence from randomized, double-blind, placebo-controlled trials. A major advantage of hdIVIg in comparison with other commonly used immunomodulating therapeutic strategies is the excellent safety profile. Accordingly, IVIgs have been used successfully for the treatment of bullous autoimmune diseases such as pemphigus and bullous pemphigoid, dermatomyositis, scleroderma, cutaneous lupus erythematosus, toxic epidermal necrolysis, and erythema exudativum multiforme. In most cases, hdIVIg is effective only in combination with other immunomodulating strategies and allows for the reduction of adjuvants. Adverse effects of hdIVIg are generally mild and self-limiting. These include headache, myalgia, flush, fever, nausea or vomiting, chills, lower backache, changes in blood pressure, and tachycardia. To avoid infusion-related rigors, headaches, and other adverse events, pre-treatment with analgesics, NSAIDs, antihistamines, or low-dose intravenous corticosteroids may be beneficial. Controlled, double-blind, long-term clinical trials and a better understanding of the complex immunomodulating mechanism of IVIg are required to ultimately optimize dose, frequency, duration, and mode of IVIg administration.

We evaluated the efficacy and toxicity of trastuzumab plus gemcitabine in patients with HER2-positive metastatic breast cancer (MBC). Sixty-four patients were enrolled, the majority of whom (95%) had been treated with an anthracycline and a taxane before study enrollment. Eligible women were treated with gemcitabine (1200 mg/m(2) weekly for 2 weeks with the third week off on a 21-day cycle) plus weekly doses of trastuzumab (4-mg/kg loading dose; 2 mg/kg thereafter) until disease progression. The median patient age was 55 years, and the median number of previously administered (including adjuvant) chemotherapy regimens was 3. Twenty-two patients were scored as 2+ for HER2 expression by immunohistochemistry; 39 patients scored 3+. Three patients were assessed as HER2-negative on central pathology review and were ineligible for evaluation. Fifty-nine of the 61 patients remained evaluable for response. The objective response rates were 38% in the intent-to-treat population (23 of 61) and 44% among the 39 patients with HER2 3+ expression. The median response duration was 5.8 months, median overall survival was 14.7 months, and median time to disease progression was 5.8 months. Trastuzumab plus gemcitabine was well tolerated. No cases of clinical congestive heart failure occurred. Grade 3/4 toxicities included asthenia in 4 patients, fever in 4, neutropenia in 18, dyspnea in 6, abdominal or back pain in 3, and edema and nausea in 1 patient each. The combination of trastuzumab plus gemcitabine appears to be well tolerated and effective for patients with HER2-positive MBC previously treated with chemotherapy.

Follicular dendritic cell (FDC) sarcomas are rare tumours, typically seen in lymph nodes. However, in about one third of the reported cases, a FDC sarcoma presents as an extranodal mass. Involvement of the gastrointestinal tract is extremely rare, and only 3 cases have been described to date. We report on a 40-year-old female patient with a follicular dendritic cell sarcoma located in the stomach and the presence of a metastasis in the liver at the time of diagnosis. Severe asthenia, nausea, back pain and loss of weight were the presenting symptoms. A CT scan of the abdomen and an upper gastrointestinal endoscopy revealed a tumour mass in the stomach. The diagnosis of a FDC sarcoma was made on histological and immunohistochemical findings. We report the second case of a FDC sarcoma presenting in the stomach. Due to its rarity, a FDC sarcoma seldom enters the differential diagnosis of spindle cells neoplasms of the gastrointestinal tract. Complete surgical resection is the treatment of choice for FDC sarcoma.

Medications have been taken since the first Mercury flight in 1967 and, since then, have been used for several indications such as space motion sickness, sleeplessness, headache, nausea, vomiting, back pain, and congestion. As the duration of space missions get longer, it is even more likely that astronauts will encounter some of the acute illnesses that are frequently seen on Earth. Microgravity environment induces several physiological changes in the human body. These changes include cardiovascular degeneration, bone decalcification, decreased plasma volume, blood flow, lymphocyte and eosinophil levels, altered hormonal and electrolyte levels, muscle atrophy, decreased blood cell mass, increased immunoglobulin A and M levels, and a decrease in the amount of microsomal P-450 and the activity of some of its dependent enzymes. These changes may be expected to have severe implications on the pharmacokinetic and pharmacodynamic properties of drug substances.

A promising approach to improving outcomes in patients with cryptococcal meningitis is to use adjunctive passive immunotherapy with a monoclonal antibody (MAb) directed against the capsular polysaccharide of Cryptococcus neoformans. This is the first application of MAb therapy for the treatment of a fungal disease in humans. We determined the safety and maximum tolerated dose of the murine anticryptococcal MAb 18B7 in a phase I dose-escalation study. The subjects were human immunodeficiency virus-infected patients who had been successfully treated for cryptococcal meningitis. Six dosing cohorts received MAb 18B7 at 0.01 to 2 mg/kg of body weight as a single infusion. Three patients each received 0.01, 0.05, 0.2, and 0.5 mg of MAb 18B7 per kg without significant adverse events. Four of the subjects who received the 1-mg/kg dose had mild study drug-associated toxicity, including transient nausea, vomiting, back pain, and urticarial rash. Two of the subjects who received 2 mg/kg developed drug-associated mild to moderate nausea, vomiting, chills, and myalgias. One of the subjects who received 2 mg/kg developed intracranial hypertension 10 weeks after MAb 18B7 administration. Serum cryptococcal antigen titers in the cohorts receiving doses of 1 and 2 mg/kg declined by a median of twofold at 1 week and a median of threefold at 2 weeks postinfusion, but the titers subsequently returned toward the baseline values by week 12. The half-life of MAb 18B7 in serum was approximately 53 h, while the MAb was undetectable in the cerebrospinal fluid of all patients. These data support the continued investigation of MAb 18B7 at a maximum single dose of 1.0 mg/kg.

Recognizing similarities and differences in symptom experiences of acute myocardial infarction (AMI) between men and women has implications for both health care providers and the general public. Rapid accurate diagnosis is necessary to implement timely lifesaving treatment. The purpose of this article is to critically review and evaluate studies that have compared symptoms of AMI between men and women. Research to date has demonstrated that during AMI, women are more likely than men to report shortness of breath, nausea, vomiting, back pain, jaw pain, neck pain, cough, and fatigue, but less likely than men to report chest pain and sweating. However, the findings were inconsistent across studies. These inconsistent findings could be attributable to methodological issues such as collecting data from medical records, small sample sizes, and controversial eligibility criteria for studies. More studies are needed to confirm gender differences in symptom experiences of AMI.
