The report describes a premature infant with necrotizing enterocolitis who developed symptoms of zinc (Zn) deficiency after three to four weeks of total parenteral nutrition (TPN). Clinical presentations included characteristic skin rash, alopecia, retarded growth, generalized edema and decreased serum alkaline phosphatase (ALP). Immune function studies revealed impaired neutrophil adhesion and mitogen-induced lymphoproliferation, whereas phagocytosis, chemotaxis and lymphocyte subsets remained normal. A high dose of elemental Zn (2.5 mg/kg/day), administered orally, improved the clinical symptoms and restored the immune function. In patients with Zn deficiency, impaired neutrophil adhesion and lymphocyte function may contribute to immunodeficiency which can be reversed with adequate Zn supplementation.

A 34-year-old woman, after 2 weeks of treatment with phenytoin and amitriptyline, developed fever and cutaneous lesions consisting of a generalized maculopapular rash and eosinophilia. Her biochemical data showed abnormal liver functions with increased levels of SGOT, SGPT, LDH, gamma-glutamyl transpeptidase and alkaline phosphatase. The skin biopsy pattern was compatible with phenytoin drug eruption of the erythemamultiforme-like type (lymphocytic exocytosis, isolated dyskeratotic cells, vacuolation of basal cells and incontinence of pigment). The patch tests were positive with phenytoin (patch test biopsy showed a typical eczematous pattern). The patch test with amitriptyline was negative. An oral challenge with amitriptyline showed an erythematous maculopapular rash. The challenge with phenytoin was not carried out because the previously abnormal liver function tests contraindicated the challenge. Although there are a few cases reported, the patch tests could be useful for diagnosing phenytoin allergy. Cross-reactivity between phenytoin and amitriptyline is possible.

The safety and tolerability of quinupristin/dalfopristin were assessed in both comparative and non-comparative trials (2298 quinupristin/dalfopristin-treated patients). In comparative clinical trials, the most frequent systemic adverse events related to quinupristin/dalfopristin were nausea (4.6%), diarrhoea (2.7%), vomiting (2.7%) and skin rash (2.5%). The comparator group showed similar rates, except that nausea was significantly more common (7.2%; P = 0.01). In non-comparative trials, arthralgia and myalgia were reported most frequently but were reversible upon treatment discontinuation. The renal, inner ear, cardiovascular and central nervous systems were not implicated as significant target organs for toxicity. The most frequent local adverse events related to infusion of quinupristin/dalfopristin were inflammation, pain, oedema, infusion site reaction and thrombophlebitis. Results of laboratory tests while on therapy were comparable for quinupristin/dalfopristin and comparator groups, except that increases in conjugated bilirubin of >5 x the upper limit of normal were reported in 5.5% of quinupristin/dalfopristin recipients; increases in total bilirubin of >5 x the upper limit of normal occurred in 1.5%. Comparator recipients more frequently had increases in alanine aminotransferase and alkaline phosphatase. Quinupristin/dalfopristin inhibits the cytochrome P450 3A4-mediated metabolism of drugs including midazolam, nifedipine, terfenadine and cyclosporin. Therefore, plasma drug monitoring and/or dosage reduction of these agents is prudent. Concomitant administration of drugs that can prolong the electrocardiographic QTc interval should be avoided. Quinupristin/dalfopristin is visually and chemically compatible with commonly used drugs of various classes, but it is not compatible with sodium chloride solution and certain other drugs, including some antimicrobials. Therefore, when prescribing quinupristin/dalfopristin, clinicians should be aware of the potential for peripheral venous intolerance, arthralgias and myalgias, increases in conjugated bilirubin, interactions with drugs metabolized by the cytochrome P450 3A4 isoenzyme and certain physico-chemical incompatibilities. However, multiple studies have shown that the safety and tolerability of quinupristin/dalfopristin are generally favourable, and that it provides clear benefits to ill patients with severe gram-positive infections.

A 73-year-old man had fever, lymphadenopathy, granulocytopenia, thrombocytopenia, ascites, pleural effusion, liver injury, and an allergic-like skin rash. Autoantibodies, such as anti-nuclear antibody, were shown, and there were lactate dehydrogenase and alkaline phosphatase anomalies and platelet-associated IgG. His liver injury resembled that in autoimmune hepatitis. He was diagnosed with Epstein-Barr virus (EBV) infection associated with autoimmunization because of his clinical course, fluctuation of anti EBV antibodies and positive EBV genome in circulating lymphocytes and serum. This case suggests a close relationship between EBV infection and autoimmunization or autoimmune-like hepatitis.

We describe our experience of quinupristin/dalfopristin for glycopeptide-resistant Enterococcus faecium (GREF) infections in 19 paediatric liver transplant recipients. The median patient age was 2 years and all were receiving immunosuppressive regimens. Quinupristin/dalfopristin was well tolerated and complete resolution of infection was seen in 74% of patients. Side-effects included reversible elevation of serum alkaline phosphatase, skin rash, itching, diarrhoea and vomiting, but therapy was not withdrawn from any patient. Quinupristin/dalfopristin appears safe and efficacious in critically ill immunocompromised children with renal or hepatic impairment.

The term mastocytosis denotes a heterogeneous group of rare hematological disorders characterized by abnormal accumulation of mast cells. While cutaneous mastocytosis is relatively frequent mast cell leukemia belongs to the rarest forms of human leukemia. In the following we present the case of an aleukemic mast cell leukemia and shall discuss the revised classification of mastocytosis based on the "Year 2000 Working Conference on Mastocytosis" held in Vienna, Austria. A 48 year-old caucasian man presented with a four-week history of diarrhea, obstipation, vomiting, rash, and mild fever. Clinical inspection revealed a disseminated itching rash and a mild hepatomegaly. Red and white blood cell counts were within the normal range. Levels of the alkaline phosphatase and serum histamine were significantly increased. There was no splenomegaly or lymphadenopathy. Cytologic and histologic investigation of the bone marrow revealed a marked increase in atypical mast cells. Since only a few circulating mast cells could be detected in a cytospin preparation of the blood, the diagnosis of an aleukemic mast cell leukemia was established. About four weeks after the diagnosis had been established, the patient died with signs of a hemorrhagic shock due to a massive gastrointestinal bleeding. Autopsy revealed widespread mast cell infiltration of bone marrow, spleen, liver and lungs, but also a small, deeply penetrating, non-specific duodenal ulcer. In conclusion, despite of presentation with signs of a primary gastrointestinal disorder, the patient was found to suffer from an exceedingly rare aleukemic mast cell leukemia ("malignant mastocytosis") and died after a total duration of the disease of only about three months.

Partially purified transducin was resolved using two-dimensional gel electrophoresis (2-DE). Peptide mass fingerprinting of several different spots believed to correspond to the 37 kDa beta-subunit of transducin (T(beta)) was performed. Spots were excised and proteolyzed using modified trypsin. Matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS) was performed on the peptide mixture resulting from each spot. As many as six spots with different pI, ranging from 5.2 to 6.1, were observed when separated using 2-DE. MALDI peptide mass fingerprinting determined with high probability that all of the spots were the same gene product, guanine nucleotide-binding protein G(I)/G(S)/G(T) beta-subunit 1 (GNB1; T(beta1)). This suggested that post-translational modification was responsible for the differences in pI. Phosphorylation experiments showed that at least one T(beta1) spot was phosphorylated in vitro with [gamma-(32)P]ATP by an endogenous kinase. Treatment of T(beta) with alkaline phosphatase caused a large change in the spot pattern of T(beta), suggesting that phosphorylated T(beta) is a substrate for alkaline phosphatase. We conclude that T(beta1) constitutes over 99% of the T(beta) expressed in bovine rod outer segments and displays structural heterogeneity that is due to post-translational modification. We also conclude that some, but not all, of the heterogeneity observed is due to phosphorylation of Tb1.

Trimethoprim-sulfamethoxazole (TMP-SMZ) is one of the most commonly used antibiotics. Although many of its adverse effects are well recognized, TMP-SMZ related hepatotoxicity is considered rare and is usually characterized by cholestasis or mixed hepatocellular-holestatic reactions. In this study, we describe the case of a previously healthy young man with acute fulminant liver failure caused by TMP-SMZ. The patient presented with complaints of 'flu-like' symptoms with myalgia and fever after taking TMP-SMZ for 7 d for otitis externa. The patient subsequently developed fever, worsening jaundice, and a rash on his neck and chest. Liver enzymes peaked on day 3 with alanine aminotransferase (ALT) 11,549, aspartate aminotransferase (AST) 23,289, alkaline phosphatase 245, and total bilirubin 10.3 mg/dL, with a conjugated bilirubin of 8.3 mg/dL, prothrombin time (PT) 60.5 s, partial normalized ratio (PTT) 49 s, and international normalized ratio (INR) 7.5. Of note, acetaminophen level on admission was undetectable. Serology for hepatitis A, B, C, cytomegalovirus, HIV, toxoplasmosis, and blood cultures were all negative. The patient developed hepatic encephalopathy with hallucination on day 4. Laboratory tests revealed a serum ammonia level of 190 U, serum creatinine kinase (CK) 10,466 (42 on admission), serum creatinine 8.2 mg/dL (1.2 on admission), and significant metabolic acidosis. Renal ultrasound was unremarkable. The patient was started on hemodialysis for acute renal failure. Meanwhile, liver transplantation assessment was also initiated. On day 8 post-admission (15 d after taking TMP-SMZ), the patient received a successful orthotopic liver transplant.

A 12 y old girl was admitted 24 days after start a WHO multidrug therapy scheme for multibacillary leprosy (dapsone, clofazimine and rifampicin) with intense jaundice, generalized lymphadenopathy, hepatoesplenomegaly, oral erosions, conjunctivitis, morbiliform rash and edema of face, ankles and hands. The main laboratory data on admission included: hemoglobin, 8.4 g/dL; WBC, 15,710 cells/mm3; platelet count, 100,000 cells/mm3; INR = 1.49; increased serum levels of aspartate and alanine aminotransferases, gamma-glutamyl transpeptidase, alkaline phosphatase, direct and indirect bilirubin. Following, the clinical conditions had deteriorated, developing exfoliative dermatitis, shock, generalized edema, acute renal and hepatic failure, pancytopenia, intestinal bleeding, pneumonia, urinary tract infection and bacteremia, needing adrenergic drugs, replacement of fluids and blood product components, and antibiotics. Ten days after admission she started to improve, and was discharged to home at day 39th, after start new supervised treatment for leprosy with clofazimine and rifampicin, without adverse effects. This presentation fulfils the criteria for the diagnosis of dapsone hypersensitivity syndrome (fever, generalized lymphadenopathy, exfoliative rash, anemia and liver involvement with mixed hepatocellular and cholestatic features). Physicians, mainly in geographical areas with high prevalence rates of leprosy, should be aware to this severe, and probably not so rare, hypersensitivity reaction to dapsone.

We previously reported that monotherapy with carbapenem or cefepime exhibited efficacy equivalent to cefepime plus an aminoglycoside as initial therapy for febrile neutropenia (FN), achieving an adequate response in two-thirds of the patients. However, only one-third of the remaining poor responders to monotherapy became afebrile after an aminoglycoside was added to the initial carbapenem or cefepime. The present study was designed to evaluate the benefit of intravenous ciprofloxacin for neutropenic patients with fever who were refractory to initial therapy given for the first 3 days. Patients with FN--as defined by an axillary temperature >or=37.5 degrees C and a neutrophil count <1,000/microL-who had no response to initial therapy with carbapenem or cefepime for 72 hours were to receive additional ciprofloxacin 600 mg/day. They were otherwise managed according to the Japanese guidelines for FN. An adequate response was defined as a decline of temperature to <37.5 degrees C within 7 days after initiation of ciprofloxacin treatment. Thirty-one patients with FN (seventeen male and fourteen female; mean age 53.1 +/- 14.8 years) were entered in the study. The initial antibiotics were cefepime (2 - 4 g/day) in twenty and carbapenem (1 - 2 g/day) in eleven. Three patients were excluded from analysis, leaving 28 patients for evaluation of efficacy. The response rate was 16/31 patients (51.6%),with four patients judged non-assessable due to adverse effects, protocol violation or early change to other agents. Adverse events occurred in seventeen patients, but all were mild and reversible. Only three patients had adverse events (skin rash, hepatic dysfunction and elevation of alkaline phosphatase in one patient, respectively) considered related to ciprofloxacin. These findings indicate that addition of intravenous ciprofloxacin is effective against FN refractory to initial antibiotic therapy and has acceptable toxicity.
