Abstract: In the period between June 2008 and August 2009, three cases of stings of Euscorpius scorpions indigenous to Italy were treated at two different emergency departments (ED) in hospitals of the Piedmont region, northwest Italy: Santa Croce e Carle General Hospital in Cuneo, and Santissima Annunziata Hospital in Savigliano. Scorpion stings in Italy are rare and not well documented in the literature; this situation may raise doubts among medical personnel as to how such lesions are best treated. Analysis of the incidents confirms that the venom of Euscorpius do not provokes systemic poisoning in humans and in these cases even dermatological reactions were not significant.
Abstract: The aim of this study was to investigate the accuracy of a critical pathway in the early stratification and management of patients with chest pain and suspected acute coronary syndrome (ACS) in the Emergency Department (ED).
Abstract: Oligoanalgesia in Emergency Departments (ED) is known to be common. The aim of our study is to determine how often patients in pain desire and receive analgesics while in the ED. Four main outcomes have been considered: desire of analgesics, administration of analgesics in the ED, correlation between initial analgesic administration and triage priority scores, patients' satisfaction at discharge during the ED visit. Pain severity was evaluated by a 10-point numerical rating scale (0Â =Â no pain, 10Â =Â worst possible pain) A total of 393 patients were enrolled in the study. The majority were non-Hispanic whites with a median age of 62Â years. Of the 393 patients, 202 expressed desire for analgesics, but only 146 received a treatment. Among patients refusing analgesics (48.6%), the most common reasons were to diagnose pain causes and pain tolerance. In multivariate analysis, pain score severity was significant factor that predicted wanting analgesics, whereas desiring analgesics was predictive factor to receive them. On the other hand, patients with pain localized in lower extremities and in nose or ear less probably received analgesia. In conclusion, the underuse of analgesics in the ED continues to represent a problem and our study demonstrates that half of all ED patients in pain desire analgesics and that only half of those wanting analgesics receive them. Patients that desired and received analgesic treatment represented the group with a higher degree of satisfaction.
Abstract: We report a case of metastatic abscesses caused by a chronic form of brucellosis in a shepherd. When she was admitted the patient was cachectic with haematological signs of phlogosis. An abdominal computed tomography scan revealed the presence of multiple hepatic and renal abscesses with a fluid mass in the abdominal wall. The blood cultures, tuberculin skin test, and Wright reaction all gave negative results, but the brucellosis Coombs test for Brucella species was highly positive. Diagnosis was confirmed by a high titre of anti-Brucella IgM antibodies. The patient started antibiotic treatment with a progressive clinical improvement, but after discharge she was lost to follow-up and died 7 months later
Abstract: To determine the impact and efficacy of a clinical pathway in the management of patients with nontraumatic and afebrile headache (NTAH) in the emergency department (ED).
Abstract: The effects of supine posture on airway responses to inhaled methacholine and deep inspiration (DI) were studied in seven male volunteers. On a control day, subjects were in a seated position during both methacholine inhalation and lung function measurements. On a second occasion, the whole procedure was repeated with the subjects lying supine for the entire duration of the study. On a third occasion, methacholine was inhaled from the seated position and measurements were taken in a supine position. Finally, on a fourth occasion, methacholine was inhaled from the supine position and measurements were taken in the seated position. Going from sitting to supine position, the functional residual capacity decreased by approximately 1 liter in all subjects. When lung function measurements (pulmonary resistance, dynamic elastance, residual volume, and maximal flows) were taken in supine position, the response to methacholine was greater than at control, and this was associated with a greater dyspnea and a faster recovery of dynamic elastance after DI. By contrast, when methacholine was inhaled in supine position but measurements were taken in sitting position, the response to methacholine was similar to control day. These findings document the potential of the decrease in the operational lung volumes in eliciting or sustaining airflow obstruction in nocturnal asthma. It is speculated that the exaggerated response to methacholine in the supine posture may variably contribute to airway smooth muscle adaptation to short length, airway wall edema, and faster airway renarrowing after a large inflation.
Abstract: A complex relationship between arachidonic acid metabolites and nitric oxide (NO) synthesis has been reported in asthma. The effects of inhaled aspirin on fractional exhaled NO (FENO) in patients with aspirin-tolerant (ATA) and aspirin-inducible (AIA) asthma compared with normal controls have been investigated.
Abstract: Severe hypoxemia may occur in patients with liver disease as a result of abnormal intrapulmonary vasodilatations (hepatopulmonary syndrome, HPS). Liver transplantation (LT) is the only effective treatment of HPS, with a quite variable delay of improvement of oxygenation. Smoking, by decreasing respiratory nitric oxide (NO), apparently contributed to improved oxygenation in a 44-year-old man with alcohol-induced cirrhosis, complicated by HPS, who underwent LT. The patient quit smoking just before LT, when his PaO(2) was 29 mm Hg and exhaled NO (eNO) 28 ppb, a value far above the normal limits (9.6 +/- 3.2 ppb). After LT, oxygenation remained poor and eNO remained high for more than 4 months, when the patient started to smoke again (blood HbCO going up to 5%). At that time eNO decreased to 6 ppb and PaO(2) increased to 67 mm Hg. The strict relationship between eNO and oxygenation observed in this case reinforces the hypothesis that NO is the most important vasodilating mediator in HPS. Smoking may have hastened the resolution of HPS after LT by inhibiting respiratory NO and/or through a generalized impairment of endothelium-dependent vasodilation.

Abstract: Cough associated with gastroesophageal reflux (GER) may originate in extrathoracic airway receptors made hypersensitive by acid-induced mucosal injury.
Abstract: Impaired arterial oxygenation, ranging from increased alveolar-arterial oxygen gradient (AaDo2) to hypoxemia, is commonly present in patients with cirrhosis. Nitric oxide (NO), through pulmonary vasodilatation, may play a major role in the oxygen abnormalities of cirrhosis. Our aim was to study the relationship between NO production and O2 abnormalities in 45 nonsmoking patients with cirrhosis and without major cardiovascular and respiratory diseases. Intrapulmonary shunting was detected by contrast-enhanced (CE) echocardiography. Lung volumes and diffusion, arterial blood gas analysis, serum NO2-/NO3-, NO output in the exhaled air, and cardiac index by the echocardiographic method were determined in all patients. Twenty-seven (60%) patients had an abnormally increased (> 15 mm Hg) AaDo2. The mean values of exhaled NO output and serum NO2-/NO3- were significantly higher in cirrhotic patients than in controls (252 +/- 117 vs. 75.2 +/- 19 nL/min/m2, P < .0001; and 47.5 +/- 29.4 vs. 32.9 +/- 10.1 micromol/L, P < .02, respectively). In all patients, there was a significant correlation between exhaled NO and AaDo2 (r = .78, P < .0001). Twelve patients (26.6%) were found to have CE-echocardiographic evidence of intrapulmonary shunting (positive CE-echo). Nine patients were considered to have hepatopulmonary syndrome (HPS) on the basis of an AaDo2 > 15 mm Hg and positive CE-echo. These 9 patients had a mean value of exhaled NO significantly higher than patients without HPS (331 +/- 73.2 vs. 223 +/- 118.4 nL/min/m2, P < .05). In all patients, cardiac index was positively correlated with exhaled NO (r = .47, P < .001) and with serum NO2-/NO3- (r = .43, P < .01). The results suggest an important role of NO in the oxygenation and circulatory abnormalities of patients with cirrhosis.
Abstract: In sinusitis bronchoconstriction is supposed to originate from pharyngobronchial reflexes triggered by seeding of the inflammatory process into the pharynx.
Abstract: Inhaled endotoxin (LPS) may cause a transient increase in airway responsiveness, possibly through a cytokine-mediated airway inflammation, which is associated with an increase in nitric oxide synthesis and release.
