Neuroleptic malignant syndrome (NMS) is a life-threatening reaction often related to neuroleptic drugs, characterized by rigidity, hyperthermia, altered consciousness, and fluctuating blood pressure. We present a case of NMS that followed a doubled oral dose of a drug compound: tranylcypromine sulfate, a monoamine oxidase inhibitor, and trifluoperazine (neuroleptic). The case was complicated by rhabdomyolisis and disseminated intravascular coagulation. It was treated successfully with dantrolene sodium and generous fluid therapy without using neuromuscular blocking agents or dopamine agonists.

Bronchoalveolar lavage was performed on 12 healthy volunteers, comprising 6 smokers and 6 nonsmokers, of ages between 21 and 52 years. The aim was to define normal variability of certain biochemical, immunologic, enzymologic and ionic parameters. The smoking habit was observed to exert a significant influence on the recovery percentage of lavage effluents (with recovery less in smokers, 53 vs. 69%) and particularly on the concentration of immunoglobulins in the lavage liquids. In particular, the IgG increased by about 4 times in smokers (1.05 vs. 0.26 mg/100 ml) and the IgA by about 3 times (0.35 vs. 0.11 mg/100 ml). The other parameters studied (total proteins, albumins, IgM, α₁-AT, K, Ca and several enzyme activities) did not differ significantly from one group to the other. Rather than an alteration in the blood-alveolar barrier from smoking, these data suggest a real local overproduction of immunoglobulins of classes G and A induced by the smoking habit. Moreover, the relatively slight individual oscillation in the values of the parameters studied in the two groups supports the possibility of employing them for diagnostic purposes in bronchopneumopathies

Abstract"llergic rhinitis "R is usually defined as an inflammatory disease of the nasal mucosa induced by an interaction of environmental allergens and IgE in sensitized patients. Its symptoms are sneezing, nasal itching, rhinorrhoea and nasal obstruction. "llergic rhinitis affects approximately -% of the population worldwide and its prevalence is increasing. Isolated "R is rare and it actually has to be considered as a systemic allergic disease, associated to comorbidities, such as conjunctivitis, chronic middle ear effusions, irregular sleep, sinusitis, lymphoid hypertrophy with obstructive sleep apnoea. The most relevant comorbidity is asthma, a heterogeneous disease, usually characterized by chronic airway inflammation in which many cells and cellular elements play an important role. "ronchial asthma is characterized by bronchial hyper-reactivity and symptoms may be triggered or worsened by factors such as viral infections, allergens, tobacco smoke, exercise and stress. " state of "minimal persistent inflammation" is permanently maintained in the lower respiratory tract of asthmatic individuals. The diagnosis of asthma is based on evidence of variable airflow limitation tested with spirometry and a positive bronchodilation reversibility test. Skin prick tests SPTs are widely used to demonstrate an immediate IgE-mediated allergic reaction. They represent a major diagnostic tool in the field of allergy. Skin prick tests have a high specificity and sensitivity for the diagnosis of inhalant allergens. Immunotherapy "IT for allergic diseases has entered in a new age characterized by the development of a few innovative therapeutic classes of standardized allergen formulations registered. Clinical randomized trials have demonstrated the efficacy of "IT in allergic rhinitis in children and in adults, expressed in terms of reduction of symptom score and use of rescue medication. The efficacy is confirmed both for subcutaneous SCIT and sublingual SLIT immunotherapy in adults and in pediatric patients. The long lasting effect of "IT after its discontinuation is an important added value of this therapy. Controlled studies are available, where the carry-over effect of "IT is demonstrated for two years after discontinuance. The capacity to prevent new sensitizations, and to modify the evolution of the disease from the rhinitis to asthma are two important features of "IT. "llergen immunotherapy showed preventive capacity and also a carryover effect once treatment is discontinued.

Twenty-three patients suffering from lower respiratory tract infections caused by Gram-negative germs were treated with aztreonam (AZT) administered according to two different regimens: 17 subjects (Group A) with 2 g i.v. every 12 h and 6 patients (Group B) with 4 g in 100 ml of saline every 24 hours. Group A included 8 cases of superinfected bronchiectasis, 8 purulent bronchitis and 1 gangrene caused by Gram-negative and anaerobic agents. Group B comprised 6 patients with severe bronchiectasis infection. Pseudomonas aeruginosa was isolated from the sputum in 10/23 cases. The treatment was performed for 10 days on the average. The local and systemic tolerability was good. Group B, with higher antibiotic sputum concentrations for at least 12 hours, attained a better response than Group A: with clinical cure in 100% vs 76% cured plus 18% improved patients; therapy lasted 9.5 days for Group B vs 10.8 days for Group A. Moreover, in 14 subjects affected by pulmonary interstitial diseases who underwent diagnostic broncho-alveolar lavage, we dosed AZT in lavage fluids about 1 hour after the injection of a 2 g dose (Group C: 8 cases) or a 4 g dose (Group D: 6 cases). In group D antibiotic concentrations were significantly higher (P less than 0.005) than group C, while all the parameters that usually define the intensity of the alveolar alterations were not significantly different. Therefore, aztreonam administration in a daily monodose seems able to assure higher and longer lasting concentrations at the site of infection.
