From July 1, 1991 to March 31, 1992, 156 patients (pts) with positive antibody titers to the human immunodeficiency virus (HIV) were seen in our clinic. A retrospective review of the epidemiology and infectious complications of these patients is presented. There were 129 males and 27 females (4.8:1, ratio). Only 10/156 (12.8%) were non-whites (13 blacks and 7 hispanics). The majority, 126 (80.7%), were 25 to 44 years old. The most common risk factor was homosexuality or bisexuality 100 (64.1%), followed by heterosexual acquisition 25 (16%), intravenous drug abuse 23 (13.7%), unknown 6 (3.8%) and transfusion-related 3 (1.9%). Sixty-five pts had no infections. In the remaining 91 pts, the infections noted were: candidiasis (54 pts); Pneumocystis carinii pneumonia (25 pts); Herpes simplex (13 pts); cytomegalovirus (CMV) retinitis (11 pts) and CMV esophagitis (1 pt), central nervous system toxoplasmosis (8); Herpes zoster (6 pts); cryptococcal meningitis (5 pts); Mycobacterium avium complex bacteremia (4 pts); Molluscum contagiosum, hepatitis-B, staphylococcal infection, perirectal abscess and oral hairy leukoplakia (2 pts each); syphilis, cryptosporidiosis, nocardiosis, histoplasmosis and laryngeal papillomatosis (1 pt each). Infections were multiple in 57/91 (62%) pts and tend to occur more often when the helper cells are < 200 47/57 (82%) pts. Appropriate antimicrobials for prophylaxis and maintenance therapy appeared to decrease the occurrence or relapse of infections such as pneumocystosis, candidiasis, cryptococcosis, tuberculosis and toxoplasmosis.

Dyslipidaemia may be treated with a number of safe and effective pharmacological agents that target specific lipid disorders through a variety of mechanisms. The bile-acid sequestrants--cholestyramine and colestipol--primarily decrease LDL cholesterol by binding bile acids, thereby decreasing intrahepatic cholesterol, and by increasing the activity of LDL receptors. Nicotinic acid lowers LDL cholesterol and triglyceride by decreasing VLDL synthesis and by decreasing free fatty acid mobilization from peripheral adipocytes. The HMG-CoA reductase inhibitors--fluvastatin, lovastatin, pravastatin and simvastatin--lower LDL cholesterol by partially inhibiting HMG-CoA reductase (the rate-limiting enzyme of cholesterol biosynthesis) and by increasing the activity of LDL receptors. The fibric-acid derivatives--bezafibrate, ciprofibrate, clofibrate, fenofibrate and gemfibrozil--primarily decrease triglyceride by increasing lipoprotein lipase activity and by decreasing the release of free fatty acids from peripheral adipose tissue. Probucol decreases LDL cholesterol by increasing non-receptor-mediated LDL clearance; as an anti-oxidant, probucol also decreases LDL oxidation; oxidized LDL which is thought to lead to atherogenesis. Although these agents have been proven safe in clinical trials, like any drug, they carry the risk for adverse effects. The bile-acid sequestrants may cause constipation, reflux oesophagitis, and dyspepsia, and may bind coadministered medications such as digitalis glycosides, beta blockers, warfarin, and exogenous thyroid hormone. Nicotinic acid use is commonly associated with flushing and pruritus and may also cause non-specific gastrointestinal complaints, hepatotoxicity (hepatic necrosis, hepatitis, or elevated liver enzymes), gout, myolysis, decreased glucose tolerance and increased fasting glucose levels, and ophthalmological complications including decreased visual acuity, toxic amblyopia, and cystic maculopathy. The HMG-CoA reductase inhibitors may produce liver enzyme elevations, creatine kinase elevations and rhabdomyolysis. The combination of a reductase inhibitor and a fibrate increases the risk for rhabdomyolysis. Possible adverse effects of the fibric-acid derivatives include abdominal discomfort, nausea, flatulence, increased lithogenicity of bile, liver enzyme elevations and creatine kinase elevations. Probucol may increase the QTc interval and may cause non-specific gastrointestinal complaints.

Fungal infections are associated with a high mortality rate after liver transplantation. To describe risk factors for fungal infections, 405 consecutive liver transplant recipients were analyzed. Forty-five patients (11%) developed invasive fungal infection. Median posttransplantation time to the first episode was 60 days. Pathogens were Candida species (spp) (n=24, 53%), Cryptococcus neoformans (n=10, 22%), Aspergillus spp (n=6, 13%), Rhizopus spp (n=l), and others (n=4). Presentations of infection included disseminated (n=9), intra-abdominal (n=9), esophageal (n=9), lung (n=8), blood (n=6), and central nervous system infections (n=3), and sinusitis with esophagitis (n=1). Eighteen patients (40%) with invasive fungal infection died, and 13 (72%) of these deaths were attributable to fungi. Mortality in the nonfungal infection group was 12%. Univariate analysis identified separate risk factors for Candida (intra-abdominal bleeding), Aspergillus (fulminant hepatitis), and cryptococcal (symptomatic cytomegalovirus infection) infections. In both univariate and multivariate analyses, a high intratransplant transfusion requirement and posttransplant bacterial infection were identified as significant risk factors for all types of fungal infection. The risk factor analysis reported here suggests that different pathogenic processes lead to Candida and non-Candida infection in liver transplant recipients. Their identification should prompt specific prophylactic measures to reduce morbidity and mortality in this population.

We conducted a feasibility study of continuous etoposide infusion, which was expected to suppress DNA repair after radiation, combined with radiation in patients with advanced non-small cell lung cancer (NSCLC). Between July 1995 and January 1997, 10 patients with NSCLC were registered. Thirty-six mg/m2/day etoposide was infused continuously for a mean of 19 days (range 14-26). Patients tolerated a mean total dose of accelerated hyperfractionated thoracic radiotherapy (1.5 Gy twice per day) of 52.6 Gy (range 33-60). The primary tumors of 7 patients showed partial responses and distant metastasis progression occurred before primary tumor progression in all 7 responders. The hematological adverse effects of chemoradiotherapy were grade 3 or 4 leukopenia in all 10 patients, grade 3 anemia developed in 3, and 2 had grade 3 thrombocytopenia. Six patients contracted infections and one of them died of pneumonia. The major non-hematological adverse effect was esophagitis, which was grade 3 in 3 patients, one of whom died of renal dysfunction. The serum etoposide concentrations were 1.6-2.0 microgram/ml, except in one patient, who had liver dysfunction due to B-type hepatitis. DNA repair gene XRCC1 mRNA expression in peripheral blood mononuclear cells was analyzed, using the reverse transcriptase-polymerase chain reaction, in 8 patients and was suppressed during etoposide infusion in 2. No relationship was observed between serum etoposide concentration and XRCC1 expression and clinical outcome. In conclusion, continuous etoposide infusion combined with thoracic radiation induces severe toxicity and should be given only after careful consideration.

Cytomegalovirus (CMV) is an important human pathogen, causing a variety of syndromes ranging from asymptomatic infections to life-threatening end-organ disease. Infections of the gastrointestinal tract are an especially common form of disease caused by CMV and are usually manifest as luminal infections, such as esophagitis or colitis. Solid organ disease caused by CMV is also known to occur, with hepatitis being the most common syndrome. The large majority of cases of tissue-invasive disease caused by CMV have been reported to occur in immunocompromised hosts. Patients at highest risk for serious CMV-mediated disease are commonly HIV infected, recipients of transplants, or are receiving potent immunosuppressive medications. Intriguingly, several recent reports have discussed the previously underappreciated role of serious forms of CMV-mediated disease occurring in immunocompetent patients. This paper reviews several recent reports addressing important aspects related to the diagnosis, treatment, and management of CMV infections of the gastrointestinal tract.

Digestive lesions were observed in 84 of 136 sea turtles (128 Caretta caretta, four Chelonia mydas and four Dermochelys coriacea) stranded in the Canary Islands between January 1993 and December 2001. In the oral cavity ulcerative and necropurulent stomatitis were the most frequently observed lesions, and in the oesophagus ulcerative and fibrinous oesophagitis, and traumatic oesophageal perforation were most frequently observed; all these lesions were mainly associated with the ingestion of fishing hooks. Different histological types of gastritis were observed in 35 of the turtles; necropurulent and fibrinous gastritis were associated with bacterial infections caused mainly by Proteus species, Vibrio alginolyticus, and Staphylococcus species, and larval nematodes of the genus Anisakis were responsible for a form of parasitic gastritis observed in 16 of the turtles. Different histological types of enteritis, including catarrhal, fibrinous, necropurulent and necrotising enteritis, affected 36 turtles; a wide range of gram-negative and gram-positive bacteria, including Bacillus species, Escherichia coli, Pasteurella species, Proteus species, Staphylococcus species, Streptococcus species and V. alginolyticus, were isolated from these lesions. All the cases of necrotising enteritis were associated with intestinal intussusception caused by the ingestion of monofilament fishing lines. Necrotising and/or multifocal granulomatous hepatitis were the lesions most commonly observed in the liver; they affected 29 of the turtles and were associated with Aeromonas hydrophila, Citrobacter species, E. coli, Proteus species, Staphylococcus species and V. alginolyticus infections. According to the stranding reports and the gross and histological lesions observed, 33 of the turtles had digestive lesions associated with the ingestion of hooks and monofilament lines, and two had lesions associated with the ingestion of crude oil.

This paper lists the pathological findings and causes of mortality of 93 sea turtles (88 Caretta caretta, 3 Chelonia mydas, and 2 Dermochelys coriacea) stranded on the coasts of the Canary Islands between January 1998 and December 2001. Of these, 25 (26.88%) had died of spontaneous diseases including different types of pneumonia, hepatitis, meningitis, septicemic processes and neoplasm. However, 65 turtles (69.89%) had died from lesions associated with human activities such as boat-strike injuries (23.66%), entanglement in derelict fishing nets (24.73%), ingestion of hooks and monofilament lines (19.35%), and crude oil ingestion (2.15%). Traumatic ulcerative skin lesions were the most common gross lesions, occurring in 39.78% of turtles examined, and being associated with Aeromonas hydrophila, Vibrio alginolyticus and Staphylococcus spp. infections. Pulmonary edema (15.05%), granulomatous pneumonia (12.90%) and exudative bronchopneumonia (7.53%) were the most frequently detected respiratory lesions. Different histological types of nephritis included chronic interstitial nephritis, granulomatous nephritis and perinephric abscesses, affecting 13 turtles (13.98%). Ulcerative and fibrinous esophagitis and traumatic esophageal perforation were the most frequently observed lesions in the esophagus, being associated in the majority of the cases with ingestion of fishing hooks. Larval nematodes of the Anisakidae family caused gastritis in 15 turtles (16.13%). Necrotizing and/or granulomatous hepatitis were the lesions most commonly observed in the liver (27.95%). Traumatic lesions included necrotizing myositis (10.75%) mainly caused by entanglement in fishing nets or boat-strikes, and amputation of 1 or 2 flippers (25.81%) by netting. Traumatic erosions and/or fractures of the carapace/plastron mainly caused by boat-strikes were also observed (26.88%). Eye lesions included heterophilic keratoconjunctivitis, ulcerative keratitis and heterophilic scleritis, affecting 7 turtles (7.53%).

Omeprazole; the first proton pump inhibitor (PPI) showing an effective acid inhibitory ability, provides the satisfactory therapy either in gastro-esophageal reflux symptom relief or in healing of erosive esophagitis. It's also effective in peptic ulcer disease. Up to date, omeprazole efficacy and safety are well established in many trials. Omeprazole-related hepatotoxicity is not very well recognized especially in pediatric population. We report a child who developed hepatitis following omeprazole intake. We believe that this is the first case report of omeprazole-induced hepatitis in pediatric population.
