After several cases of occupational asthma had been reported in a coffee processing factory in England, 197 coffee workers representing 80% of the production workforce were studied to determine the factors affecting the development of work related respiratory symptoms of wheeze, cough, and dyspnoea. Two computer administered questionnaires concerning the presence of respiratory symptoms and the occurrence of work related respiratory symptoms were used. Workers underwent skin prick testing to green coffee bean extract (GCB) and 11 common inhalant allergen extracts and bronchial provocation testing with methacholine. The presence of specific immunoglobulin E (IgE) antibodies to GCB and castor bean extract (CAB) were determined by a radioallergosorbent test (RAST). The prevalence of work related respiratory symptoms was 12.7%, bronchial hyperresponsiveness 30%, atopy 54%, positive GCB skin prick test 14.7%, positive GCB RAST 14%, and positive CAB RAST 14.7%. None of the workers was sensitised to fungi present in the factory and the numbers of certain species of fungi, despite being greater than may be found out of doors or in an uncontaminated indoor environment, were fewer than are generally associated with the presence of work related respiratory symptoms among agricultural workers. Storage mites were not isolated. Green coffee bean extract and CAB RAST were significantly correlated using the McNemar test but there was limited allergenic cross reactivity in RAST inhibition studies of the two extracts. The only factors that were significantly and independently associated with work related symptoms were CAB RAST and duration of employment. Bronchial hyperresponsiveness was not independently associated with work related respiratory symptoms. The significant independent associations of bronchial hyperresponsiveness included GCB RAST, duration of employment, and resting forced expiratory volume in one second. Exposure to CAB, a highly potent antigen, may be overriding the effects of other factors such a GCB, atopy, bronchial hyperresponsiveness, and smoking. This study suggests that CAB contamination remains a potential problem in the coffee processing industry and all efforts to eliminate it from the working environment should continue.

At the two largest open air markets in Kumasi, Ghana, interviews were conducted with 143 women who had at least one child aged less than five years. Researchers wanted to examine their knowledge, attitude, and practices concerning acute respiratory infection (ARI) in children. The women tended to be married, Christian, from the Ashanti tribe, aged 20-29 years, and to have 2-3 living children. 73.4% had a child or children who had suffered from cough and fever within the last six months. 73.4% named exposure to cold as a direct cause of cough. Many women incorrectly blamed worm infestation for causing cough and fever (21%) and constipation for causing cough (25.9%). None mentioned pathogens as a cause of cough and fever. None said that good ventilation and avoidance of overcrowding prevent cough and fever. The more serious the symptoms, the more likely the mothers were to seek treatment at a health care facility (e.g., cough only, 0.7%; cough and fever, 6.3%; cough, fever, and anorexia, 30%; and cough, fever, and lethargy, 57.3%). Common home care practices for treating a runny nose included ephedrine or other types of nasal drops, herbal medicines, antipyretics, and antibiotics. 39.9% would use antibiotics to treat coughs. Honey and cough syrup were often used to treat cough and fever. Some herbal and home care therapies had potentially harmful effects. For example, 25.9% said that they used castor oil and enemas to prevent ARI. The women had an acceptable knowledge score on severity of symptoms (mode = 15/20; range = 11-18). These findings indicate a need for a health education program targeting mothers of children aged less than five years.

(R)-3-(1-[2-(4-benzoyl-2-(3,4-difluorophenyl)-morpholin-2-yl)- ethyl]-4-phenylpiperidin-4-yl)-1-dimethylurea (SR 144190) is a new non-peptide antagonist of tachykinin NK2 receptors. SR 144190 potently and selectively inhibited neurokinin A binding to NK2 receptors from various species, including humans. In in vitro functional assays, it was a potent, selective and competitive antagonist of NK2 receptors with apparent affinities (pA2 values) between 9.08 and 10.10. In vivo, SR 144190 blocked [Nle10]neurokinin A-(4-10)-induced bronchoconstriction in guinea pigs (ID50 = 21 micrograms kg-1 i.v. and 250 micrograms kg-1 i.d.) and [beta Ala8]neurokinin A-(4-10)-induced urinary bladder contraction in rats (ID50 = 11 micrograms kg-1 i.v. and 190 micrograms kg-1 i.d.). It prevented citric acid-induced cough and airway hyperresponsiveness to acetylcholine in guinea pigs (1 mg kg-1 i.p.) as well as castor oil-induced diarrhoea in rats (0.01-10 micrograms kg-1 s.c. or p.o). Finally, it blocked the turning behaviour induced by intrastriatal injections of [Nle10]neurokinin A-(4-10) in mice (ID50 = 3 micrograms kg-1 i.v. and 16 micrograms kg-1 p.o.).

Lung cancer in women is increasing in worldwide. This process beginning with the difference on the susceptibility of lung cancer in women smokers may be different from men in the prognosis. In this study, it was aimed to evaluate the clinical features, and prognostic factors of female patients with lung cancer diagnosed between January 2000-December 2005. The data of 109 patients data was evaluated. The mean age was 59.40 +/- 11.56 and 17 (15.6%) patients were smokers. In 20 patients (18.3%) having a family history of cancer, 55% of them had a relative with lung cancer. In admission, cough (81.7%), dyspnea (78.9%), chest pain (40.3%) were the most frequent presenting symptoms. The most common site of tumoral lesion in bronchoscopy were right upper lobe (16.5%). In the study group histopathological diagnosis were as follows; adenocarcinoma (44.9%), small cell lung cancer (SCLC) (19.3%), squamous cell (10.1%), non-small cell lung cancer (NSCLC) --undefined (22.0%), carsinoid tumors (2.8%), in non-smokers adenocarcinoma was significantly higher than smokers (44.9%/17.7%) (p< 0.001). 61.9% of NSCLC patients and 57.1% of SCLC patients had a stage IV disease at the initial evaluation. The most common sites of metastasis were bone (28.4%), liver (22.9%), and brain (11.9%), there were multiple metastasis in 10 patients. Median survival time was found as 288 days. In univariate analysis, comorbidity, primary tumor stage, bone metastasis, advanced disease stage, ECOG performance score >or= 2 and supportive care alone were poor prognostic factors. In multivariate analysis, poor performance status (p= 0.003), advanced disease stage (p= 0.002) and bone metastasis (p= 0.04) were negatively related to survival. In women, the definition of the clinical features, disease course and survival related factors may contribute to our future treatment approaches based on our national data.

Leptohyptis macrostachys, previously known as Hyptis macrostachys Benth., is used in folk medicine to relieve the symptoms of asthma, cough, and bronchitis. Recently, we showed that the ethanol extract obtained from Leptohyptis macrostachys has selective spasmolytic activity on guinea pig ileum. Therefore, the aim of this study was to characterize the spasmolytic mechanism of this extract, investigated whether it presents toxicological and antidiarrheal activities. Therefore, the crude ethanolic extract of Leptohyptis macrostachys was analyzed by high-performance liquid chromatographic-diode array detection (HPLC-DAD). The spasmolytic effect was evaluated on guinea pig ileum, toxicological activity using rats and antidiarrheal activity using male and female mice. In HPLC-DAD analysis, Rosmarinic acid (5.44%) was the most abundant phenolic compound, being considered as a chemical marker. The spasmolytic potency of the extract on histamine-induced contraction was reduced in the presence of 1 mM TEA+, a selective big-conductance K+ channels blocker (BKCa). The extract produces a dose-dependent antidiarrheal activity, inhibiting equipotently defecation frequency and liquid stool formation. In addition, the extract has inhibited in a dose-dependent manner both castor oil-induced intestinal transit and intestinal fluid content. Thus, the spasmolytic activity of the extract involves positive modulation of BKCa and its antidiarrheal activity is related to inhibition of intestinal motility and secretion.
