Four patients with stable or progressive cutaneous T-cell lymphoma treated with oral bexarotene received oral rosiglitazone. After 16 weeks of combination therapy, skin score decreased in two patients. Pruritus was alleviated in 3 of 4 patients, whereas quality of life was unchanged. Adverse events included hyperlipidemia, anemia, neutropenia, and lymphopenia.

The patient was a 61-year-old man who suffered from advanced gastric cancer, and a distal gastrectomy was performed (T3N2P1CY1, Stage IV). He was treated with chemotherapy of TS-1 alone (100 mg/day, days 1-28 with two weeks rest). Six months later he complained of lumbago and appetite loss, then was admitted to the hospital with obstructive jaundice. Total bilirubin (T-Bil) was increased to 11.3 mg/dl. CT scan examination revealed peritoneal dissemination with much ascites and dilatation of intrahepatic bile ducts. Endoscopic drainage was tried, but was discontinued due to stenosis of gastroduodenal anastomosis. Ultimately, T-Bil was elevated to 25.2 mg/dl, and he could not sleep comfortably because of a severe itch and an irritating feeling. Weekly paclitaxel therapy was started (70 mg/m(2), day 1, 8, 15, once a week for 3 weeks followed by a week rest as one cycle). One month after the first infusion therapy, the obstructive jaundice was notably improved and the ascites disappeared completely, so he was discharged. For about one year, he was treated with this chemotherapy as an outpatient. The toxic events were anemia (grade 3) and alopecia (grade 1).

The in-vivo efficacies of the artesunate malartin, alone and in combination with amodiaquine, have been assessed against uncomplicated cases of Plasmodium falciparum malaria attending two treatment centres in Cameroon (the WHO/University of Buea malaria health post in Bolifamba and the University of Buea's health centre in Molyko). The 213 participants were treated for 3 days (malartin-amodiaquine) or 5 days (malartin alone) and then followed-up on days 3, 7 and 14. Only 86 of the patients given malartin alone and 80 of those given malartin-amodiaquine completed follow-up. Most patients given malartin alone showed an adequate clinical and parasitological response (91.9%), the rest showing late parasitological failure (7.0%) or early treatment failure (1.2%). The corresponding values for the malartin-amodiaquine combination were slightly better, at 93.8%, 5.0% and 1.2%, respectively. No late clinical failures were recorded in either treatment arm. In both treatment arms, the prevalence of anaemia in the treated adults (aged>15 years) and children decreased significantly during follow-up (P<0.05). Both regimens were well tolerated and neither gave rise to any serious adverse effects. The most common side-effects were dizziness and fatigue in those given malartin alone and fatigue, itching and nausea in those given malartin-amodiaquine. Three days of treatment with the malartin-amodiaquine combination appears to be slightly more effective and a slightly better choice than 5 days of treatment with malartin alone.

Hemodiafiltration with larger amounts of substitution fluid offers an optimal way to remove uremic substances. Hemodiafiltration could be indicated for all hemodialysis patients. Large observational studies have shown an association of a lower mortality risk with hemodiafiltration using more than 15 liters of substitution fluid. Specific indications should be considered because hemodiafiltration has been reported to be effective against hyperphospatemia, malnutrition, insomnia, irritability, restless-leg syndrome, polyneuropathy, anemia, itching and joint pain, and may prevent dialysis-associated amyloidosis. In this chapter, hemodiafiltration prescriptions concerning blood and dialysate fl ow, infusion rate, vascular access and frequency are detailed.

Skin itching (pruritus) affects 50%-90% of patients undergoing peritoneal dialysis or hemodialysis and the symptoms range from localized and mild to generalized and severe. Among the dermatological abnormalities associated with end-stage renal disease, pruritus is the most prevalent. Of all systemic disorders, uremia is the most important cause of pruritus. The mechanism underlying uremic pruritus is poorly understood: secondary hyperparathyroidism, divalent-ion abnormalities, histamine, allergic sensitization, proliferation of skin mast cells, iron-deficiency anemia, neuropathy and neurological changes, or a combination of these have been hypothesized. Severe pruritus not only affects the quality of life but is also associated with poor outcome in chronic hemodialysis patients. No specific, effective treatment is currently available for uremic pruritus. Further studies are necessary to evaluate the long-term efficacy and safety of a novel kappa-opioid agonist, nalfurafine. Early diagnosis and treatment of uremic pruritus focusing on general strategies that include the optimization of dialysis dose, erythropoiesis-stimulating agents, and management of secondary hyperparathyroidism is recommended.

Two captive agoutis (Dasyprocta mexicana) died of anemia with centrilobular hepatocellular necrosis (2/2), severe flea ectoparasitism (2/2), and cardiomegaly attributed to anemia (1/2). Other agoutis were similarly parasitized and one had anemia. Fleas were manually removed and all agoutis treated topically with propoxur and selamectin and moved to another enclosure. No additional cases of fatal anemia were seen. Cutaneous lesions suggestive of hypersensitivity were observed in three additional agoutis with dorsal alopecia (3/3), a penetrating wound associated with pruritus and self-mutilation in the flank (2/3), flea ectoparasitism at the time of morphologic diagnosis (1/3), and hyperplastic perivascular dermatitis (3/3). One of these died of bacterial infection of the wound. Similar but milder skin disease was seen in 3 out of over 30 maras (Dolichotis patagonum) housed in the same exhibit. Fleas collected from all the fatal agouti cases and maras were classified in the genus Echidnophaga based on the angular front margin of head, contracted thorax, absence of genal and pronotal combs, and the fact that fleas did not jump. These findings suggest that flea ectoparasitism may be an important cause of morbidity and mortality in captive rodents.

In 2006 an outbreak of canine distemper affected 14 young domestic ferrets in Barcelona, Spain. Their clinical signs included a reduced appetite, lethargy, dyspnoea, coughing, sneezing, mucopurulent ocular and nasal discharges, facial and perineal dermatitis, diarrhoea, splenomegaly and fever. Late in the course of the disease, general desquamation and pruritus, and hyperkeratotic/crusting dermatitis of the lips, eyes, nose, footpads, and perineal area were observed. None of the ferrets developed neurological signs. Non-regenerative anaemia and high serum concentrations of alpha- and beta-globulins were the most common laboratory findings. Most of the animals died or were euthanased because of respiratory complications. Postmortem there were no signs of lung collapse. Distemper was diagnosed by direct immunofluorescence of conjunctival swabs or pcr of several organs, and histology revealed the characteristic eosinophilic intracytoplasmic and intranuclear inclusion bodies of canine distemper virus in several organs. The minimum incubation periods calculated for six of the ferrets were 11 to 56 days, and in 13 of the ferrets the signs of disease lasted 14 to 34 days. Inclusion bodies compatible with infection by herpesvirus were found in the lungs of one of the ferrets.

Bed bugs, leeches, and hookworm-related cutaneous larva migrans are skin infestations that are usually considered of minor importance because they produce discomfort rather than cause or transmit disease. Bed bugs have been increasing tremendously in high-income countries in recent years, causing distress to affected individuals and economic loss. Infestation by land leeches causes mainly unpleasant skin reactions, whereas infestation by aquatic leeches may be more dangerous, leading to anemia and in severe cases, to death. Cutaneous larva migrans produces an intense pruritus that can be exasperating for the patient and cause sleep disturbance. An overview is given of these three infestations with a discussion of the causative agents, transmission, clinical manifestations, diagnosis, and treatment.

Ferumoxytol is an intravenous iron preparation for treatment of the anemia of chronic kidney disease (CKD). It is a carbohydrate-coated, superparamagnetic iron oxide nanoparticle. Because little free iron is present in the preparation, doses of 510 mg have been administered safely in as little as 17 seconds. Two prospective, randomized studies compared two doses of ferumoxytol 510 mg given in 5 +/- 3 days with 3 weeks of oral iron 200 mg/day (as ferrous fumarate) in anemic patients with CKD. One study enrolled 304 patients with stages 1-5 CKD (predialysis), and the other study enrolled 230 patients with stage 5D CKD (undergoing hemodialysis). In both studies, a greater increase in hemoglobin level from baseline to end of study (day 35) was noted in patients who received ferumoxytol compared with those who received oral iron (mean +/- SD 0.82 +/- 1.24 vs 0.16 +/- 1.02 g/dl in patients with stages 1-5 CKD and 1.02 +/- 1.13 vs 0.46 +/- 1.06 g/dl in patients with stage 5D CKD, p<0.001). A greater proportion of both predialysis and hemodialysis patients who received ferumoxytol had hemoglobin level increases from baseline of 1 g/dl or more compared with those who received oral iron (p<0.001). In a prospective, double-blind, crossover study of more than 700 patients with CKD stages 1-5D that compared the safety of ferumoxytol with normal saline injection, the rates of treatment-related adverse events were 5.2% and 4.5%, respectively. Serious treatment-related adverse events were seen in one patient in each treatment group. The most common adverse events with ferumoxytol occurred at the injection site (bruising, pain, swelling, erythema). Dizziness, nausea, pruritus, headache, and fatigue occurred in less than 2% of patients receiving ferumoxytol, with a similar frequency noted after administration of normal saline. In short-term studies, intravenous ferumoxytol was safely and rapidly administered, and was more effective than oral iron therapy in increasing hemoglobin levels in anemic patients with CKD. Long-term clinical trials with clinical outcomes and studies comparing ferumoxytol with other parenteral iron agents will help define the role of ferumoxytol in treating the anemia of CKD.

Skin and wound care in epidermolysis bullosa (EB) is specific both to the type of EB and to individual wounds within each child. Availability of dressings and personal preference are also paramount in the selection of materials. The ideal dressing is yet to be developed, although there are now a variety of suitable dressings available. This article discusses current techniques of wound and dressing management for EB simplex, junctional EB, and dystrophic EB. Factors adversely affecting healing include anemia, malnutrition, infection, and pruritus.
