Apolizumab (Hu1D10), a humanized monoclonal anti- Human leukocyte antigen -DR beta-chain antibody, mediates apoptosis of chronic lymphocytic leukemia (CLL) cells in vitro. We conducted a phase I/II dose-escalation study of thrice-weekly apolizumab (1.5, 3.0, 5.0 mg/kg/dose) for 4 weeks in relapsed CLL. Two of six patients at 5.0 mg/kg/dose developed treatment-related dose-limiting toxicity (aseptic meningitis, hemolytic uremia). Other toxicities included infusion toxicity, urticaria, and headache. Eleven patients were enrolled in a phase I/II expansion to evaluate the maximum tolerated dose (MTD) of 3.0 mg/kg/dose. In total, 23 patients were enrolled (22 CLL, 1 ALL). Nineteen patients with CLL were treated at or above the MTD. One partial response was observed, and three patients had stable disease exceeding 6 months. Pharmacokinetic analysis demonstrated a dose-dependent C(max) increase and serum antibody accumulation after week 1 of therapy. Given the toxicity and lack of efficacy in this and other trials in lymphoma and solid tumors, further development of apolizumab was discontinued.

In non-endemic countries, acute (invasive) schistosomiasis (AS) is typically seen in non-immune travellers, whereas chronic schistosomiasis is more frequently diagnosed in immigrants. Travellers with AS initially present with non-specific signs such as fever, cough, headache, and urticaria. Life-threatening cardiac and neurological complications may occur. The positive diagnosis of AS relies on seroconversion, which appears together with hypereosinophilia approximately 3 weeks after the onset of symptoms. When prescribed during AS, praziquantel usually does not prevent the chronic phase of the disease and is associated with exacerbation of signs and symptoms in approximately 50% of cases. According to the published literature, corticosteroids may be recommended alone or in association with praziquantel. When associated with corticosteroids, pharmacokinetic interactions may impair the efficacy of praziquantel. We suggest that corticosteroids should be restricted to use in patients with systemic complications of AS, whereas praziquantel should be initiated only when ova are detected in either stools or urine, depending on the culprit species.

The Ugandan national control programme for schistosomiasis has no clear policy for inclusion of preschool-children (</=5 years old) children. To re-balance this health inequality, we sought to identify best diagnosis of intestinal schistosomiasis, observe treatment safety and efficacy of praziquantel (PZQ), and extend the current WHO dose pole for chemotherapy. We examined and treated 363 preschool children from shoreline villages of Lakes Albert and Victoria, and found that 62.3% (CI(95) 57.1-67.3) of the children were confirmed to have intestinal schistosomiasis. One day after treatment, children were reported as having headaches (3.6%), vomiting (9.4%), diarrhoea (10.9%) and urticaria/rash (8.9%) with amelioration at 21-day follow-up, where the parasitological cure rate was found to be 100.0%. Height and weight data were collected from a further 3303 preschool children to establish and validate an extended PZQ dose pole that now includes two new height-intervals: 60-84 cm for one-half tablet and 84-99 cm for three-quarter tablet divisions; which would result in 97.6% of children receiving an acceptable dose (30-60 mg/kg). To conclude, preschool children in lakeshore communities of Uganda are at significant risk of intestinal schistosomiasis; we now strongly advocate for their immediate inclusion within the national control programme to eliminate this health inequity.

Mucopolysaccharidosis type VI (MPS VI), or Maroteaux-Lamy syndrome, is a lysosomal storage disorder that results from a deficiency of the enzyme N-acetylgalactosamine-4-sulfatase or arylsulfatase B (ASB). It is a relatively rare disorder, with an estimated incidence of 1 in 248,000 to 1 in 300,000. The diagnosis is made on the basis of findings of elevated urine glycosaminoglycans and a deficiency of ASB activity in leukocytes or cultured fibroblasts. In treatment of MPS VI, enzyme replacement therapy (galsulfase; human recombinant ASB enzyme) became available. Infusions of galsulfase were generally well tolerated. But in some patients, infusion-associated reactions including rash, urticaria, headache, hypotension, nausea, and vomiting were documented and were managed successfully by interrupting or slowing the rate of infusion and/or by the administration of antihistamines, antipyretics, corticosteroids, or oxygen. Here, we report a case with MPS VI who developed thrombocytopenia after third dose of therapy. To the best of our knowledge, this is the first report about thrombocytopenia associated with galsulfase therapy in the literature. Additionally, with this report, we want to share our approach for this case.

Exercise-induced anaphylaxis (EIA) is a syndrome in which patients experience the symptoms of anaphylaxis, which occur only after increased physical activity. It is characterised by a gradual development of symptoms: itching, erythema, urticaria, angioedema, anaphylactic shock (hypotension, syncope, loss of consciousness, shortness of breath, wheezing, nausea and vomiting), and at the end of the late phase prolonged urticaria and headache. The triggering factors for EIA are as follows: significant exposure to airborne allergens, insect sting, weather extremes, higher air humidity, taking nonsteroidal anti-inflammatory drugs. The most frequent causative nutritive allergens include wheat, crabs and shells. Prophylactic management for EIA comprises avoding the triggers. Exercise or other physical activity should be performed in proximity of medically trained companion.

Leucovorin is a reduced form of folic acid, which has multiple uses.(1) In this case report, it is used in combination with fluorouracil in the treatment of colon cancer. We describe a 53-year-old male, who was started on FOLFOX 6 + bevacizumab who experienced a hypersensitivity reaction to leucovorin. There have been very few cases of leucovorin hypersensitivity reactions reported in the literature. In this case, symptoms include flushing, hives, body pain, headaches, elevated blood pressures, and general discomfort. Although leucovorin reactions are considered rare, one should be aware of the types of reactions that can occur with leucovorin.

One of the most important scientific discoveries of the last century was that persistent infection by some types of HPV is a precondition for the development of cervical cancer. The oncogenic types of HPV are also associated with other tumours (vaginal, vulvar and anal carcinomas, tumours of the head and neck, urethra and penis). Two preventive vaccines are currently available (Cervarix and Gardasil). Both have shown very good efficacy, safety and tolerability profiles. Nonetheless, extensive vaccination requires long-term monitoring of safety and tolerability. The aim of our study was to evaluate the safety and tolerability of the bivalent vaccine Cervarix in Italy. Every participant in the study completed a questionnaire after each dose of vaccine received, with a view to recording adverse events during the first 7 days after vaccination. We registered local (pain, redness, swelling) and systemic symptoms (fever, headache, myalgia, fatigue, arthralgia, itching, gastrointestinal disorders, rash and urticaria). A total of 4,643 subjects were recruited. In all, 7,107 questionnaires were collected: 3,064 after the first dose, 2,367 after the second and 1,676 after the third. No serious adverse events were observed. The most frequent local symptom was pain at the injection site, while fatigue, headache and myalgia were the most common systemic reactions. Pain was reported more frequently after the first dose than after the others, while all the other local and general symptoms were reported most frequently after the third dose. Almost all of the local and general reactions proved to be of negligible intensity and duration and required no medical intervention. Our results show better tolerability of the vaccine in comparison with the data from some controlled clinical studies and from other surveillance programmes conducted internationally. That tolerability proved to be better than in clinical studies could be explained by the absence of the typical apprehension felt by subjects involved in clinical experimentation.

Introduction. The objective was to evaluate the toxicity of poisoning by metam sodium, a dithiocarbamate fumigant, the breakdown products of which are methyl isothiocyanate (MITC), carbon disulphide (CS2), and dihydrogen sulphide (H2S). Methods. This is a retrospective, observational case series of metam sodium exposure cases reported to the Angers Poison and Toxicovigilance Centre from 1992 through 2009. Results. A total of 106 cases of metam sodium exposure were recorded and 102 cases were included in this study. All cases of exposure were unintentional. Occupational poisoning occurred in eight cases. The most common route of exposure was inhalation (n = 96). In 79 cases, the patients were people living near fields where metam sodium had recently been applied. Most of the reported symptoms involved irritation of the eyes (n = 76), throat and nose (n = 65), attributable to MITC. Cough and dyspnoea occurred in four cases but no persistent, irritant-induced asthma or persistent exacerbation of asthma was observed. Sixteen patients at two different sites of pollution were exposed to emanations from the drainage system in their homes following the illicit discharge of metam sodium into the sewers. Most presented with nausea and headaches, but only four experienced eye or throat irritation. A breakdown product other than MITC was involved: air analysis at one site revealed the presence of CS2 (337 mg/m(3)) and no H2S. Two of these patients, who had consumed some alcohol, experienced dysgeusia but no disulfiram-like reaction. The only lethal case recorded was a truck driver who was found dead of acute lung injury after falling into a tank that had previously contained metam sodium. Two patients who ingested a dilute solution, presented with mild epigastric pain. Four skin exposures caused erythema (n = 2), moderate burns (n = 1), and urticaria (n = 1). According to the poisoning severity score, their symptoms were minor in 99% of cases. Conclusion. Acute metam sodium exposure usually causes minor symptoms. They vary as a function of the circumstances of exposure, which determine the degradation product that forms. On contact with moist soil, metam sodium decomposes into MITC and causes irritant symptoms. Under specific conditions, such as a spillage in the drainage system, metam sodium can degrade into CS2 and cause neurological signs.

Brucellosis is a worldwide zoonotic gram-negative bacterium of worldwide distribution. Its role in causing miscarriage in animals is well documented. Data on its role in human abortion are very few. This paper was carried out on selected women with abortion or history of abortion to clarify the role of brucellosis in human abortion. A total of 129 women were selected from Al-Zahraa University Hospital and other obstetric and gynecological hospitals in the vicinity of Greater Cairo. The patients were subjected to clinical, gynecological, and serodiagnosis (STAT and ELISA) of brucellosis. Also, routine urine (Nuclepore technique) and stool (Kato thick smear) was done as well as skin tests and ELISA for common hepatic parasites. The results showed that 59 had brucellosis, 27 had toxoplasmosis, 15 had fascioliasis and 29 had other cause(s) of abortion. Meanwhile, none had visceral leishmaniasis or schistosomiasis mansoni. the signs and symptoms of all patients were hepatosplenomegaly (31.1%), lower back abdominal pain (23.13%), lassitude, headache (each, 21.7%), lymphadenopathy (20.1%), vomiting (17.1%), loss of appetite, myalgia or diarrhea or constipation (each, 15.42 %), weight loss (14.6%), chest pain (13.9%), night sweating or dizziness (11.65%), fever or right sided abdominal pain (each, 10.7%), chills (7.71%), urticaria or monoarthralgia (each, 3.85%). These signs and symptoms were confusing for specific clinical picture of brucellosis. Brucellosis patients were successfully treated with a combination of Rifampicin 600 mg. once daily and Septrin 800 mg twice daily for 6 weeks. Cure was achieved clinically and serologically. Patients with toxoplasmosis or fascioliasis were also treated with Fasinex and Mirazid respectively. Other parasites were also treated.

An unusual disease, mastocytosis challenges the pathologist with a variety of morphologic appearances and heterogeneous clinical presentations ranging from skin manifestations (pruritus, urticaria, dermatographism) to systemic signs and symptoms indicative of mast cell mediator release, including flushing, hypotension, headache, and anaphylaxis among others. In this article, we focus on recognizing the cytology, histopathology, clinical features, and prognostic implications of systemic mastocytosis, a clonal and neoplastic mast cell proliferation infiltrating extracutaneous organ(s) with or without skin involvement. Diagnostic pitfalls are reviewed with ancillary studies to help unmask the mast cell and exclude morphologic mimics.
