The diagnosis of urinary tract sepsis is being made more often today because of increased awareness of the condition and improved techniques in the detection and management of genitourinary disorders. Patients developing urinary tract sepsis (bacteremia or septicemia) usually demonstrate certain predisposing factors: underlying chronic disease, advanced age, general debility, or recent urinary tract sepsis is easily made in a patient who has a sudden onset of fever, chills, malaise, nausea, and vomiting, along with tachycardia and a drop in blood pressure. Cultures should be taken from urine and blood samples, but therapy should be instituted immediately rather than after obtaining the results of cultures.

Gram-negative osteomyelitis frequently responds poorly to conventional therapy. Ciprofloxacin displays excellent in vitro activity against gram-negative bacilli and offers the potential for outpatient therapy. In this ongoing study, ciprofloxacin therapy is being evaluated for the treatment of gram-negative osteomyelitis. Twenty-three patients (16 men and seven women) have been treated under the protocol (750 mg orally twice daily for 1.5 to six months), and 14 patients have completed therapy. All patients had either growth on bone cultures from an open or percutaneous biopsy, or an arthrocentesis to confirm the diagnosis. Involved sites included ankle or tibia (seven patients), vertebra (four patients), hip (five patients), metatarsal (four patients), phalanx (two patients), and metacarpal (one patient); 16 patients had chronic disease, and seven patients had acute disease. Patients had a total of 28 gram-negative bacilli, 12 gram-positive cocci, and one anaerobic gram-negative rod, for an average of 1.8 pathogens per patient. Eighteen of the 28 gram-negative bacilli were Pseudomonas species. The geometric mean minimal inhibitory concentration for all the gram-negative bacilli was 0.15 microgram/ml. The geometric mean minimal inhibitory concentration for the gram-positive isolates was 0.41 microgram/ml. All patients who completed therapy experienced a cure, with a mean follow-up of 6.1 months. Infections in all patients, except for two who are still taking ciprofloxacin, are resolving, both clinically and radiologically. One patient who was not eligible for the protocol experienced a superinfection with methicillin-resistant Staphylococcus aureus. Side effects have included urticaria, lethargy, nausea, and transient elevations of liver and renal function test results. Overall, ciprofloxacin therapy was well tolerated. This study suggests that ciprofloxacin holds promise for the outpatient treatment of gram-negative osteomyelitis.

Anorexia is associated with disorders of all systems. Anorexia represents a consistent clinical manifestation during acute and chronic pathophysiological processes (infection, inflammation, injury, toxins, immunological reactions, malignancy and necrosis). Anorexia during disease can be beneficial or deleterious depending on the timing and duration. Temporary anorexia during acute disease may be beneficial to an organism since a restriction in the intake of micro- and macro-nutrients will inhibit bacterial growth. Long-term anorexia during chronic disease, however, is deleterious to an organism and may be associated with cachexia, which can ultimately result in death. Various mechanisms participate in the anorexia observed during disease, including cytokine action. Anorexia induced by cytokines is proposed to involve modulation of hypothalamic-feeding associated sites, prostaglandin-dependent mechanisms, modifications of neurotransmitter systems, gastrointestinal, metabolic, and endocrine factors. In addition, the anorexia-cachexia syndrome is multifactorial and may involve chronic pain, depression or anxiety, hypogeusia and hyposmia, chronic nausea, early satiety, malfunction of the gastrointestinal system, metabolic alterations, cytokine action, production of other anorexigenic substances and/or iatrogenic causes (chemotherapy, radiotherapy). Cachexia may result not only from anorexia and a decreased caloric intake, but also from malabsorption and losses from the body (ulcers, hemorrhage, effusions), or a change in body metabolism. Research has focused on potential interventions to modify anorexia during disease and the anorexia-cachexia syndrome. Nutritional modifications and the use of specific steroids (such as megestrol acetate) are being tested in the clinical setting. Understanding the specific mechanisms responsible for anorexia during disease as well as their interactions is essential to develop interventions for the control of anorexia (during a critical time in a specific disease), and to devise less toxic immunotherapeutic regimens using cytokines.

Lansoprazole is an inhibitor of gastric acid secretion and also exhibits antibacterial activity against Helicobacter pylori in vitro. Current therapy for peptic ulcer disease focuses on the eradication of H. pylori infection with maintenance therapy indicated in those patients who are not cured of H. pylori and those with ulcers resistant to healing. Lansoprazole 30 mg combined with amoxicillin 1g, clarithromycin 250 or 500mg, or metronidazole 400 mg twice daily was associated with eradication rates ranging from 71 to 94%, and ulcer healing rates were generally >80% in well designed studies. In addition, it was as effective as omeprazole- or rabeprazole-based regimens which included these antimicrobial agents. Maintenance therapy with lansoprazole 30 mg/day was significantly more effective than either placebo or ranitidine in preventing ulcer relapse. Importantly, preliminary data suggest that lansoprazole-based eradication therapy is effective in children and the elderly. In the short-term treatment of patients with gastro-oesophageal reflux disease (GORD), lansoprazole 15, 30 or 60 mg/day was significantly more effective than placebo, ranitidine 300 mg/day or cisapride 40 mg/day and similar in efficacy to pantoprazole 40 mg/day in terms of healing of oesophagitis. Lansoprazole 30 mg/day, omeprazole 20 mg/day and pantoprazole 40 mg/day all provided similar symptom relief in these patients. In patients with healed oesophagitis. 12-month maintenance therapy with lansoprazole 15 or 30 mg/day prevented recurrence and was similar to or more effective than omeprazole 10 or 20 mg/day. Available data in patients with NSAID-related disorders or acid-related dyspepsia suggest that lansoprazole is effective in these patients in terms of the prevention of NSAID-related gastrointestinal complications, ulcer healing and symptom relief. Meta-analytic data and postmarketing surveillance in >30,000 patients indicate that lansoprazole is well tolerated both as monotherapy and in combination with antimicrobial agents. After lansoprazole monotherapy commonly reported adverse events included dose-dependent diarrhoea, nausea/vomiting, headache and abdominal pain. After short-term treatment in patients with peptic ulcer, GORD, dyspepsia and gastritis the incidence of adverse events associated with lansoprazole was generally < or = 5%. Similar adverse events were seen in long-term trials, although the incidence was generally higher (< or = 10%). When lansoprazole was administered in combination with amoxicillin, clarithromycin or metronidazole adverse events included diarrhoea, headache and taste disturbance. In conclusion, lansoprazole-based triple therapy is an effective treatment option for the eradication of H. pylori infection in patients with peptic ulcer disease. Preliminary data suggest it may have an important role in the management of this infection in children and the elderly. In the short-term management of GORD, lansoprazole monotherapy offers a more effective alternative to histamine H2-receptor antagonists and initial data indicate that it is an effective short-term treatment option in children and adolescents. In adults lansoprazole maintenance therapy is also an established treatment option for the long-term management of this chronic disease. Lansoprazole has a role in the treatment and prevention of NSAID-related ulcers and the treatment of acid-related dyspepsia; however, further studies are needed to confirm its place in these indications. Lansoprazole has emerged as a useful and well tolerated treatment option in the management of acid-related disorders.

In this study, the causes, predisposing factors and clinical features of chronic daily headache in children and adolescents were studied within the population of patients attending a specialist headache. The International Headache Society's (IHS) criteria for the diagnosis of chronic tension type headache (CTTH) were assessed for their applicability in the paediatric age group. Over a period of three years, demographic and clinical data were collected prospectively on all children who attended the clinic and suffered from daily attacks of headache. One hundred and fifteen children and adolescents (32% of all clinic population) had chronic daily headache, of whom 93 patients (81%) fulfilled the IHS criteria for the diagnosis of CTTH. They were between 3-15 years of age (mean: 11.1, SD: 2.3) and their female to male ratio was 1.2 : 1. Around one third of the patients also suffered from migraine (mainly migraine without aura). The headache was described as mild in 60.9%, moderate 36.5% and severe 2.6%. Headache was located at the forehead in 53% or over the whole of the head in 29.6%. Pain was described as 'just sore' or dull by 73.9%. During attacks of headache, at least half the patients reported light intolerance, noise intolerance, anorexia or nausea. Thirty-two percent of patients had at least one underlying chronic disease that may have contributed to the pathogenesis of the CTTH. Eleven percent had serious stressful events related to family illnesses and in four patients headaches were triggered by family bereavement. Fourteen percent were investigated with neuroimaging and 22% were referred for clinical psychology assessment and management. In conclusion, CTTH is a common cause of headache in children attending a specialist headache clinic. The clinical features closely match those of adult population and the IHS criteria for the diagnosis of CTTH can be adapted for use in children. Predisposing stressful risk factors, physical or emotional, are present in a large proportion.

Eosinophilic gastroenteritis is an uncommon chronic disease, of unknown cause, characterized by eosinophilic infiltration of the gastrointestinal tract, which is usually associated with peripheral blood eosinophilia. The symptoms of this complex disorder are variable, and frequently include abdominal pain, nausea, diarrhea, protein losing enteropathy and malabsorption. In general, patients can be successfully treated with corticosteroids, but relapses are common. We present the first case of a 6-year-old boy with Albright's hereditary osteodystrophy (Pseudohypoparathyroidism Ia) associated with eosinophilic gastroenteritis. Alternatives to traditional treatment with corticosteroids are discussed.

Viral hepatitides are common diseases of modern man in both industrialized and developing countries, with a varying prevalence of particular types and mode of transmission. In current medicine, viral hepatitides are classified in the A-E nomenclature, differentiating viruses that can be etiologically defined with certainty on the basis of serum markers and hepatitides exhibiting all clinical and laboratory characteristics of viral hepatitis but of as yet nondemonstrable causative agents, classified in the non-A, non-E hepatitis group. Two issues are of high relevance in the pathogenesis of viral hepatitides: route of transmission (fecal-oral or parenteral) and basic mechanism of hepatocyte lesion. Although all hepatitis viruses replicate within the hepatocyte, the exact mechanism of hepatocyte necrosis has not yet been fully elucidated, i.e. direct cytotoxicity or hepatoprogressive immune response mediated primarily by the specific cytotoxic CD8 lymphocytes. Depending on the site of entry, the virus replicates in the adjacent lymphatic tissue for some time, followed by primary viremia, virus replication in the lymphoreticular organs (lymph nodes, liver, spleen), and eventual entry in the target cells--hepatocytes, accompanied by a varying grade of necrosis and inflammatory reaction. The clinical and laboratory signs of the disease correspond to the degree of liver necrosis and are not specific for particular types of viral hepatitis. The most frequent symptoms common to all types of viral hepatitis of moderate severity include elevated body temperature persisting for days, fatigue, gradual loss of appetite, nausea, dull pain and discomfort on DRL, vomiting, multiple loose stools, dark urine, jaundice of the skin and mucosa, and light stools. Generally, the ultimate outcome of the disease is elimination of the virus and complete recovery, however, a fulminant course with lethal outcome or transition to chronic disease may also occur, making viral hepatitides a major public health problem worldwide. In classical infectology, four clinical stages of the disease have been described: incubation or preclinical stage characterized by intensive virus replication; prodromal or preicteric stage with pronounced general symptoms of infection; icteric stage; and stage of recovery. The stages may show great interindividual variation in length and severity. The development of molecular technologies over the last decade has greatly contributed to better understanding of the pathogenesis of viral hepatitides and allowed for appropriate monitoring of the effect of antiviral therapy. However, major disadvantage of these tests is their high cost. The basic clinical characteristics of and diagnostic options for particular types of viral hepatitis are described, with special reference to the latest important concepts on the disease pathogenesis.

Obesity is a multifactorial, chronic disorder that has reached epidemic proportions in most industrialised countries and is threatening to become a global epidemic. Clinical management of obese patients is complex and serious doubts have arisen with regard to safety and efficacy of drug therapy. Following the withdrawal of fenfluramine and dexfenfluramine in 1997, interest has focused on novel anti-obesity drugs. Pharmacological approaches to the management of obesity can, in broad terms, use different distinct strategies: firstly, to reduce energy intake; secondly, to increase energy expenditure; and thirdly, to alter the partitioning of nutrients between fat and lean tissue. Sibutramine is a serotonin-noradrenaline (norepinephrine) reuptake inhibitor indicated for the management of obesity in conjunction with a reduced calorie diet. The pharmacological mechanisms by which sibutramine exerts its weight loss effect are likely due to a combination of reduced appetite, feelings of satiety and possibly the induction of thermogenesis. The efficacy of sibutramine for inducing initial weight loss and the subsequent maintenance of weight loss is well proven in short- and long-term clinical trials of up to 2 years' duration. Most individual placebo-controlled trials and pooled estimates found that the drug produced statistically significant greater weight loss than placebo at all observed endpoints (weighted mean difference for weight change at 8 weeks: -3.4 kg; mean difference range for weight change at 6 months: -4.0 to -9.1 kg; and at 1 year: -4.1 to -4.8 kg). The most frequent dosage regimen in these trials was 10-20 mg daily. Findings suggested a dose-effect relationship in terms of weight loss. Sibutramine was also associated with better weight maintenance relative to placebo (statistically significant difference). Results from mainly small trials showed that sibutramine produced more favourable outcomes in terms of loss of fat mass, reduction in body mass index and loss of > or = 5-10% of initial bodyweight. The most commonly reported adverse effects of sibutramine are headache, constipation and nausea. Certain adverse events associated with the nervous system, including dizziness, dry mouth and insomnia, are reported by > 5% of patients receiving sibutramine. Increases in blood pressure and heart rate were possible adverse effects that require regular monitoring especially in obese hypertensive patients. Neither left-sided cardiac valve disease nor primary pulmonary hypertension was associated with the use of sibutramine. The assessment of the benefit-risk profile of sibutramine remained positive, although the product must be kept under regular review.

Opioid-induced sedation is a major complication in patients with cancer pain. This study assessed the effectiveness of donepezil in opioid-induced sedation and related symptoms in patients with cancer pain. Twenty-seven patients who were receiving strong opioids for pain and reported sedation were enrolled. Donepezil 5 mg was given every morning for 7 days. Changes between baseline and Day 7 in sedation, pain, fatigue and other symptoms were evaluated using the Edmonton Symptom Assessment Scale. Fatigue was also measured using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue). Overall usefulness of donepezil was measured by the patient at the end of the study. In 20 evaluable patients, sedation, fatigue, anxiety, well-being, depression, anorexia and problems with sleep were significantly improved. Side effects included nausea, vomiting, diarrhea, muscle and abdominal cramps, and anorexia. Overall, however, the treatment was well tolerated. Donepezil appears to improve sedation and fatigue in patients receiving opioids for cancer pain. Randomized controlled trials of this agent are justified.

The use of highly active antiretroviral therapy (HAART) has served to significantly reduce the mortality of HIV-infected persons. However, this treatment is associated with a host of adverse effects: fatigue, nausea, pain, anxiety and depression. Rather than utilise traditional pharmacological treatments for these effects, many HIV/AIDS patients are utilising adjunct therapies to maintain their quality of life while they undergo treatment. Exercise has consistently been listed as one of the most popular self-care therapies and a small number of studies have been conducted to examine the impact of exercise on the most common self-reported symptoms of HIV and AIDS and the adverse effects of treatment. Although the results are generally positive, there are clear limitations to this work. The existing studies have utilised small samples and experienced high rates of attrition. In addition, the majority of the studies were conducted prior to the widespread use of HAART, which limits the ability to generalise these data. As a result, data from other chronic disease and healthy samples are used to suggest that exercise has the potential to be a beneficial treatment across the range of symptoms and adverse effects experienced by HIV-infected individuals. However, additional research is required with this population to demonstrate these effects.
