Mastocytosis is a rare disease of mast-cell proliferation with involvement of the reticuloendothelial systems including skin, bone, gastrointestinal tract, liver, lungs, spleen, and lymph nodes. Systemic mastocytosis is characterized by a combination of symptoms that relate to the mast cells' release of vasoactive substances, such as histamine. These symptoms include urticaria pigmentosa, flushing, syncope with hypotension, headaches, nausea, vomiting, diarrhea, and occasional bronchospasm. The diagnosis of mastocytosis is typically based on the presence of the characteristic extraosseus manifestations. A well recognized roentgenographic feature seen in 70-75% of patients with mastocytosis is diffuse osteolysis and osteosclerosis, affecting primarily the axial skeleton and the ends of the long bones. Rarely, the bony involvement consists of generalized osteoporosis, which may lead to pathologic fracture, or solitary lesions (mastocytomas) which may cause symptoms of localized pain. Four patients with previously diagnosed systemic mastocytosis had unusual skeletal lesions. Clinical and laboratory evaluation of these patients eventually led to the correct diagnosis of systemic mastocytosis. We report these four cases to emphasize the need for thorough evaluation of unusual musculoskeletal findings in association with extraosseus symptoms that are characteristic of mastocytosis. Knowledge of a wide differential diagnosis of unusual skeletal lesions should include systemic mastosytosis.

Radiologists have traditionally been responsible for the sedation of children undergoing radiological investigations. Anaesthetists are becoming increasingly involved in providing sedation and/or anaesthesia in this environment. The sedation of a child for a CT scan who has recently been given oral contrast medium (OCM) may pose anaesthetists a number of dilemmas. This is a retrospective survey of 149 intravenous pentobarbital sedations administered by radiologists to children (age range three months to seven years three months, weight range 5 kg to 28.9 kg) undergoing upper abdominal CT after recent ingestion of OCM. The average patient received pentobarbital 4.6 mg.kg-1. 141 patients (94.6%) received pentobarbital as the only sedative agent, whereas eight patients (5.4%) required supplementary sedation (midazolam +/- fentanyl). There were no failed sedations. 36 complications occurred during 22 sedations (14.7% of total), with the most common being desaturation, vomiting, airway secretions, airway obstruction, coughing and bronchospasm.

A 78-year-old lady initially presented with painful hips, low back pain, lethargy and weight loss. She had a past history of osteomalacia. Investigations revealed evidence of malabsorption and jejunal biopsy revealed sub-total villous atrophy in keeping with coeliac disease. Peripheral blood film was within normal limits. She responded well clinically to a gluten-free diet and calcium and vitamin D supplementation. Four years after the initial diagnosis she presented acutely with vomiting, pleuritic chest pain, pyrexia and bronchospasm. Blood cultures confirmed the presence of Streptococcus pneumoniae and she was treated appropriately with ampicillin. Despite this she died shortly after admission. It is recognized that blood film examination alone cannot exclude hyposplenism complicating coeliac disease and it is presumed that this was the reason for the development of fatal pneumococcal septicaemia in this patient. Prophylactic vaccination may be appropriate in hyposplenism secondary to coeliac disease.

Peripheral blood progenitor cell reinfusion (PBPC) in patients undergoing high-dose chemotherapy (HDC) for poor prognosis malignancies, has been described as causing possible acute gastrointestinal (nausea, vomiting), allergic (oedema, bronchospasm, anaphyl- axis), renal (proteinuria, haematuria) and/or cardiovascular (hypotension, arrhythmia, conduction disturbances, transient ischaemic phenomena) toxicities. To establish the clinical relevance of these observations and the possible relationship with different HDC regimens used, we performed a clinical and instrumental evaluation on 33 patients with advanced breast cancer, non-Hodgkin's lymphoma, Hodgkin's disease, relapsed ovarian cancer, Ewing's sarcoma, extragonadal germinal tumour and small cell lung cancer. They underwent at least one reinfusion each for a total of 51 studied procedures. No patient had a previous history of cardiovascular disease or significant intercurrent illness such as diabetes or liver, renal or neurologic impairment. All patients had totally implanted central venous catheters, through which the transplants had been collected and reinfused without technical consequences. To evaluate cardiovascular function, we continuously monitored 12-lead ECGs, with arterial pressure (AP) measurements every 5 min from the beginning of the procedure to 15 min after the reinfusion ended. We did not observe any significant differences between basal and subsequent steps in AP, heart rate, PQ and QTc time, P wave and QRS complex duration or P wave and QRS electrical axes. No patient showed any ST-T tract pathological abnormality, but one patient developed a transient ectopic atrial rhythm, without any haemodynamic disfunction and with spontaneous reversion to sinus rhythm. No patient complained of symptoms of haemodynamic failure. Gastrointestinal side-effects appeared to be strictly related to speed of reinfusion and to the number of packs reinfused, probably reflecting on the amount of dimethylsulphoxide infused. In one patient a tonic-clonic seizure occurred during a vomiting episode, but no patient developed allergic or renal toxicities. We conclude that PBPC reinfusion, if managed according to the procedure we propose in patients without organic impairment, is a safe procedure not associated either with increased risk of acute arrhythmias or ischaemic or significant systemic acute toxicities.

From 1984 in N.N. Burdenko Surgical clinic of I.M. Sechenov MMA more than 500 horizontal gastroplasties (HGP) were performed for the treatment of patients with extreme degree of alimentary-constitutional obesity. In 1996 for the first time in our country HGP was performed, including laparoscopic method, with use of regulated silicon bandage "Lap-Band" (LB) made by "Bioenterics", USA. Laparoscopic HGP was performed in 29 patients (7 males, 22 females), aged from 23 to 60 years, mean age was 34.2 +/- 10 years. Minimal body weight was 85 kg, maximal--180 kg, mean--131 +/- 27.2 kg. Mean body mass index was 47 +/- 9.9 kg/m2. Open operations were performed in 14 cases, laparoscopic operations--in 15 cases. 11 laparoscopies were performed in initial stages in very stout patients and in the absence of laparoscopic equipment. In 3 cases the conversion from laparoscopic to open operation was necessary: in 1st case because of hemorrhage from lesser omentum's vessels, when hemostasis cannot be performed by laparoscopy; in 2nd case as a result of bronchospasm associated with tense pneumoperitoneum in the patient with bronchial asthma; in 3rd case because of significant enlargement and rigidity of liver left lobe, which didn't permit to create the space for manipulations in cardial portion of the stomach. The mean bed day turnover after traditional HGP with LB and after laparoscopic HGP was 12.2 and 5.4 respectively. Intraoperative complication was observed in one case--hemorrhage from lesser omentum's vessels. One complication was observed in immediate postoperative period, on the 6th day after traditional HGP: the eventration as a result of hard diarrhea due to antibacterial treatment was diagnosed. One more complication was observed in a year after traditional HGP: small stomach evacuatory function disorders as a result of its significant dilatation. These disorders occurred because of gastric mucosa inflammatory edema, decrease of anastomosis diameter and frequent vomiting due to aspirin taking. In this case the repeated operation--bandage's reposition was performed. There were no other complications. The rate of repeated operations was 4% which agrees with literature data.

CAMPATH-1H (CP-1H) is a humanized monoclonal antibody directed against the CD52 antigen with promising therapeutic effects in patients with small cell lymphocytic non-Hodgkin's lymphomas (NHL) of B- and T-cell type. We report about the response and toxicity of CP-1H in 18 patients with B-cell NHL who were treated in four clinical centers in Germany. Sixteen patients suffered from a low-grade and two from a high-grade NHL. All patients had received chemotherapy before and had either relapsed or were refractory to conventional therapy. Two patients received CP-1H in a dose-range finding trial once weekly and 16 patients as a fixed dose of 30 mg three times weekly. Of 18 patients, 8 (44%) achieved a clinical response, 2 (11%) had stable disease, and 5 (28%) had progressive disease. Four patients could not be evaluated for response because of death (two patients) and serious adverse events (two patients). All patients with response to CP-1H had a low-grade NHL. Nonhematological toxicity was severe in two patients who suffered from WHO grade III/IV bronchospasm. Common acute adverse events (WHO grade I-III) included fever, chills, rigor, urticaria, nausea, and vomiting. Eleven patients suffered from bacterial or viral infections; some had recurrent infections. A total of 12 different infections were reported. The most frequent infections were caused by herpesvirus (seven patients). Hematological toxicity included thrombocytopenia in four and lymphocytopenia in seven patients. Although the antibody is humanized, the nonhematological toxicity was substantial and probably due to a cytokine release syndrome. Prophylactic treatment of the side effects is strongly recommended for patients treated either with CP-1H alone or in combination with chemotherapy.

N-(3,5-Dichloro-1-oxido-4-pyridinyl)-8-methoxy-2-(trifluoromethyl)-5-quinoline carboxamide (SCH 351591) has been identified as a potent (IC(50) = 58 nM) and highly selective type 4 phosphodiesterase (PDE4) inhibitor with oral bioactivity in several animal models of lung inflammation. N-(3,5-Dichloro-4-pyridinyl)-8-methoxy-2-(trifluoromethyl)-5-quinoline carboxamide (SCH 365351), the only significant in vivo metabolite, is also a potent and highly selective PDE4 inhibitor (IC(50) = 20 nM). Both SCH 351591 and SCH 365351 inhibited cytokine production in human blood mononuclear cell preparations. Oral SCH 351591 significantly attenuated allergen-induced eosinophilia and airway hyperreactivity in allergic guinea pigs at doses as low as 1 mg/kg. In this model, oral SCH 365351 showed similar potency. When SCH 351591 was administered orally to allergic cynomolgus monkeys at 3 mg/kg, Ascaris suum-induced lung eosinophilia was blocked. Hyperventilation-induced bronchospasm in nonallergic guinea pigs, a model for exercise-induced asthma, was also suppressed significantly by oral SCH 351591 at 0.3 mg/kg. Cilomilast (SB 207499; Ariflo), a PDE4 inhibitor currently being developed for asthma and chronic obstructive pulmonary disease (COPD), was 10- to 30-fold less potent than SCH 351591 at inhibiting guinea pig lung eosinophilia and hyperventilation-induced bronchospasm. In a ferret model of emesis, maximum nonemetic oral doses of SCH 351591 and cilomilast were 5 and 1 mg/kg, respectively. Comparison of plasma levels at these nonemetic doses in ferrets to those at doses inhibiting hyperventilation-induced bronchospasm in guinea pigs gave a therapeutic ratio of 16 for SCH 351591 and 4 for cilomilast. Thus, SCH 351591 exhibits a promising preclinical profile as a treatment for asthma and COPD.

DMSO is an amphipathic molecule with a highly polar domain and two apolar methyl groups, making it soluble in both aqueous and organic media. It is one of the most common solvents for the in vivo administration of several water-insoluble substances. Despite being frequently used as a solvent in biological studies and as a vehicle for drug therapy, the side-effects of DMSO (undesirable for these purposes) are apparent from its utilization in the laboratory (both in vivo and in vitro) and in clinical settings. DMSO is a hydrogen-bound disrupter, cell-differentiating agent, hydroxyl radical scavenger, intercellular electrical uncoupler, intracellular low-density lipoprotein-derived cholesterol mobilizing agent, cryoprotectant, solubilizing agent used in sample preparation for electron microscopy, antidote to the extravasation of vesicant anticancer agents, and topical analgesic. Additionally, it is used in the treatment of brain edema, amyloidosis, interstitial cystitis, and schizophrenia. Several systemic side-effects from the use of DMSO have been reported, namely nausea, vomiting, diarrhea, hemolysis, rashes, renal failure, hypertension, bradycardia, heart block, pulmonary edema, cardiac arrest, and bronchospasm. Looking at the multitude of effects of DMSO brought to light by these studies, it is easily understood how many researchers working with DMSO (or studying one of its specific effects) might not be fully aware of the experiences of other groups who are working with it but in a different context.

The organic phosphorous compounds (OPC) include both the military grade nerve agents and the organic phosphorous pesticides. The major mechanism of OPC toxicity is through inhibition of acetylcholinesterase in neuronal synapses leading to excess acetylcholine and overstimulation of target organs. Signs and symptoms depend on the affinity of the OPC for muscarinic versus nicotinic receptors, and are likely to include both. Muscarinic symptoms may include diarrhea, urination, bronchospasm, bronchorrhea, emesis, and salivation. Nicotinic symptoms such as paralysis and fasciculations may also occur. Central nervous system toxicity may include seizures, altered mental status, and apnea, and require prompt intervention. Treatment includes early airway and ventilatory support as well as antidotal therapy with atropine, pralidoxime, and diazepam. Goals of therapy include prevention and rapid treatment of hypoxia and seizures, as these are linked to patient outcome.

A case report of an unusual formaldehyde exposure that had happened accidentally is described. A 54-year-old male ingested 10% formaldehyde and inhaled while vomiting and he developed cough, dyspnea and wheezing with prevalent ronci and bilateral infiltrates on chest x-ray (cxr). His pulmonary symptoms and FEV1 responded well to systemic corticosteroids and nebulised salbutamol given for the possible diagnosis of hypersensitivity and/or chemical pneumonitis, and infiltrates were cleared. Two weeks after the incident, he had massive haemoptysis, fever, leucocytes, prevalent crackles, bronchospasm, and new infiltrates on CXR. After an antibiotic and steroid therapy, his symptoms and crackles relieved, radiographic infiltrates were regressed. Delayed type hypersensitivity to formaldehyde patch test was appropriate with late-onset symptoms. This is a first case of pneumonitis as well as asthma different from the occupational exposure to formaldehyde. This data suggests direct and indirect effects of formaldehyde in healthy human airways.
