Implementation and dissemination of an African American popular opinion model to improve lupus awareness: an academic-community partnership.

OBJECTIVE: Lupus is a chronic, autoimmune disease that disproportionately affects African Americans. We adapted the Centers for Disease Control and Prevention's Popular Opinion Leader model to implement an intervention tailored for African American individuals that leverages an academic-community partnership and community-based social networks to disseminate culturally appropriate lupus education. METHODS: Academic rheumatologists, social scientists, and researchers in Boston, MA and Chicago, IL partnered with local lupus support groups, community organizations, and churches in neighborhoods with higher proportions of African Americans to develop curriculum and recruit community leaders with and without lupus (Popular Opinion Leaders; POLs). POLs attended four training sessions focused on lupus education, strategies to educate others, and a review of research methods. POLs disseminated information through their social networks and recorded their impact, which was mapped using a geographic information system framework. RESULTS: We trained 18 POLs in greater Boston and 19 in greater Chicago: 97% were African American, 97% were female; and the mean age was 57 years. Fifty-nine percent of Boston POLs and 68% of Chicago POLs had lupus. POLs at both sites engaged members of their social networks and communities in conversations about lupus, health disparities, and the importance of care. Boston POLs documented 97 encounters with 547 community members reached. Chicago POLs documented 124 encounters with 4083 community members reached. CONCLUSIONS: An adapted, community-based POL model can be used to disseminate lupus education and increase awareness in African American communities. Further research is needed to determine the degree to which this may begin to reduce disparities in access to care and outcomes.

Idiopathic pulmonary lymphoid diffuse hyperplasia.

We describe a 70-year-old woman affected by diffuse pulmonary lymphoid hyperplasia (DPLH). DPLH is a rare clinical-pathological entity generally associated with connective tissue diseases, but we diagnosed our case as an idiopathic DPLH. To the best of our knowledge, this is the first case of idiopathic DPLH reported in medical literature.

Acute fibrinous and organising pneumonia in Whipple's disease.

We report a case of acute fibrinous and organising pneumonia in Whipple's disease with lung improvement after antibiotic therapy. In our knowledge this is the first report of Whipple's disease with acute fibrinous and organising pneumonia.

Respiratory bronchiolitis associated with interstitial lung disease.

Respiratory bronchiolitis associated with interstitial lung disease (RB-ILD), first described by Niewoehner et al in an autopsy study of cigarette smokers who died from non pulmonary causes in 1974, is a rare entity that should be distinguished from the other interstitial lung diseases and in particular from desquamative interstitial pneumonia, although the two conditions share a similar histopathological pattern. RB-ILD is clearly connected with tobacco smoking and has been inserted in the "smoking related interstitial lung diseases" together with DIP and Cell histiocytosis of Langerhans; it may also be associated with occupational exposure to machine fumes. The following is a case report of a patient with both smoking and occupational exposure.

GENEBU Project. Equipment and drugs used for home nebulizer therapy in Italy.

The GENEBU Project is an open, observational survey evaluating home nebulizer practices in Italy. It consecutively included patients who were referred to one of the 27 participating chest clinics from May to December 1999 and who had been using a home nebulizer in the previous six months. The information source was a self-administered questionnaire compiled by the enrolled subjects. We collected 1257 questionnaires. The nebulizer equipment was heterogeneous, with at least 92 different models. Jet nebulizers were 90% of the total; 53% of these had a glass reservoir. Almost 80% of the patients selected the nebulizer themselves without any medical advice. In addition, most patients (> 80%) did not receive information on both the interface system and the optimal fill volume of the nebulizer. Corticosteroid nebulisation was widespread (74%), for both occasional and regular daily use, for both acute and chronic diseases from upper to lower airways. Beta 2-agonist (55%), anticholinergic (37%), mucolytic (32%) drugs were also often nebulised. More than 90% of patients mixed some active drugs. We conclude that the nebulizer equipment for home aerosol therapy was very heterogeneous and, probably, not always utilised at its best in Italy. The mixing of drugs and the widespread use of corticosteroids were peculiarities of home nebulizer therapy in Italy.

Massive unilateral hydrothorax as the only clinical manifestation of ovarian hyperstimulation syndrome.

We describe the case of a 36 old woman with a right massive hydrothorax resulting from Controlled Ovarian Hyperstimulation (COH) for infertility. This complication is defined as Ovarian Hyperstimulation Syndrome (OHSS) which usually includes abdominal pain, nausea and ascites, rarely involving the respiratory apparatus. The usual determining factors of OHSS are the presence of high serum estradiol levels and pregnancy. In the case that we describe the serum estradiol levels during COH were monitored and were slightly higher than the COH alarm threshold and the patient was not pregnant.

Anthracyclines in non-small cell lung cancer.

The literature concerning the use of anthracyclines in the treatment of non-small cell lung cancer (NSCLC) is reviewed here. Overall, the activity of doxorubicin (DOXO) is unsatisfactory, whereas, the analogous epidoxorubicin (EPI) yields a 30% response rate (RR) when administered at intermediate-high doses. All active drugs, including EPI, should be considered to design the most active combination. Mainly, in the setting, in which an objective response is very important, for instance the neo-adjuvant pre-operatory setting.

A three-drug regimen (gemcitabine, ifosfamide and cisplatin) for advanced non-small-cell lung cancer.

We have carried out a pilot study on 25 non-small cell lung cancer patients, administering the combination of gemcitabine at the dose of 1000 mg/m2 on days 1 and 8, ifosfamide 1500 mg/m2 on days 1 and 2 (plus mesna as uroprotector) and cisplatin 40 mg/m2 on days 1 and 2, every 21 days. Granulocyte Colony Stimulating Factor was employed in all cases from day 10 to day 18 at the dose of 300 microg daily. An objective response was observed in 11 cases (44%). The regimen was active, but toxicity was remarkable with some cases of severe myelosuppression and mucositis.

GENebu Project: home nebulizer use and maintenance in Italy.

Due to the lack of information on this topic, the Educational Group of the Italian Association of Hospital Pneumologists performed an open, multicentre, observational survey to evaluate home nebulizer practices in Italy. From May-December 1999, all patients attending one of the 27 participating chest clinics throughout Italy and who were or had been using a home nebulizer in the previous 6 months were consecutively enrolled. All patients completed a self-administered questionnaire on their current practices of home nebulization. Of the 1,721 questionnaires delivered, 1,257 were returned with an overall response rate of 73%. Most patients (82.8%) reported using their nebulizer for bronchopulmonary symptoms and the remaining patients only used theirs for upper respiratory tract diseases. Subjects using their nebulizer for lower respiratory symptoms were older (p<0.001), predominantly female (p<0.001) and used their nebulizer more frequently (p<0.001). Forty per cent of patients >60 yrs old used their nebulizer regularly, at least once a day. More than 60% of respondents never received any information from healthcare workers on the correct usage of their nebulizer, and >75% received no information on nebulizer hygiene and care. Patients who received information on the use and maintenance of their nebulizer from caregivers more commonly attended to these practices (p<0.01). The present survey suggests that home nebulizer use and maintenance in Italy are heterogeneous, and there is the need to implement better nebulizer practice.

Perception of methacholine-induced airway obstruction in asthmatics.

The main objective of this study was to examine the perception of the first symptom during methacholine bronchoconstriction as soon as it occurred, and in the second instance to quantify the intensity of the breathlessness by means of the Borg Scale performed at the end of challenge so to not determine any difficulties for identification of the first symptom. A methacholine challenge test was carried out in 139 symptom-free asthmatics with a normal pulmonary function. When the first symptom was reported by the subject, the forced expiratory volume in one second (FEV1) was measured immediately. FEV1 was expressed as a percentage of the best personal value (FEV1%BPV). The intensity of the breathlessness was rated using a modified Borg Scale at the end of the challenge test so as not to confuse the patient. Seven subjects felt nothing during challenge. The first symptoms varied: constriction behind the breastbone (49%), inspiratory shortness (16.5%), coughing (10%), wheezing, throat constriction, general chest tightness, pain behind the sternum, and a sensation of rheum behind the sternum. FEV1%BPV at the first symptom was 80.5 +/- 10 (range 41-99). No symptom was perceived by 42% of the subjects within the 80-100 range of FEV1%BPV. FEV1%BPV at the first symptom was related to the log of the provocative dose causing a 20% fall in FEV1 (r = 0.2, p < 0.05). An inverse correlation between Borg Score and final FEV1%BPV (r = -0.25, p < 0.01) was found at the end of challenge. A subgroup of 39 subjects with similar final FEV1%BPV values (68-72) showed a correlation between the Borg Score at end of challenge and FEV1%BPV at the first symptom (r = 0.59, p < 0.001). The first symptom of the methacholine-induced bronchoconstriction varies in asthmatics and may be atypical, the bronchoconstriction level at which it is felt also varies among individuals, highly methacholine-responsive subjects perceive the bronchoconstriction later, while late perceivers of the first symptom show less intense breathlessness at the end of challenge. The measurement of the patient's ability to perceive asthmatic symptoms during the methacholine challenge test could be used to single out poor perceivers.

Sequential high dose-density chemotherapy with two active regimens for advanced small cell lung cancer.

16 patients with advanced small cell lung cancer were treated with a combination of cyclophosphamide (1000 mg/m2 day 1), epidoxorubicin (60 mg/m2 day 1) and vincristine (1.4 mg/m2 day 1) every 14 days for six cycles followed by a combination of cisplatin (40 mg/m2 days 1 & 2) and etoposide (100 mg/m2 days 1-3) every 14 days for four cycles. Shortening of intervals was obtained with the prophylactic employment of granulocyte colony-stimulating factor (filgrastim, 300 mcg subcutaneously from day 5 to dsy 10). In 11 patients ratio between actually delivered dose intensity and planned dose intensity of > 80% was obtained. Toxicity was acceptable and no life-threatening toxicities were observed. An objective response (partial or complete) was observed in 11 patients. The new regimen, incorporating the concepts of dose-intensification and sequential administration of regimens, is feasible and may be considered for further studies.

[Mesothelioma registry of the Liguria region. Incidence and occupational etiology in a high risk area]. / Registro mesoteliomi della Liguria. Incidenza ed eziologia professionale in un'area ad alto rischio.

This paper presents the epidemiological analyses based on the first 5 years of activity of the Mesothelioma Registry of Liguria (REM). REM is a population-based cancer registry specialized in the study of both the incidence and etiology of primary pleural and peritoneal mesothelioma in Liguria (Italy). The REM completes normal clinical information with occupational and environmental anamnestic data in order to identify working and living areas at risk for asbestos-related pathologies. The REM started its activity in 1994 describing the incidence of pleural mesothelioma (PM) exclusively in the population resident in the city of Genoa (660,000 inhabitants); since 1996 the REM has studied the entire Liguria Region (1,640,000 inhabitants), where nearly 120 new cases of PM are diagnosed annually (20% are women). In the city of Genoa, between 1986-1987 and 1997-1998, PM crude incidence rate rose from 13.8 to 26.7 per 100,000 males over 40 years old. From 1994 to 1998 the REM registered 495 new patients with histologically (62%) and cytologically (9%) confirmed diagnosis of PM. 54% of them were immunocytohistochemically evaluated. Occupational information has been gathered for 248 subjects, i.e., 61% of cases with sure or probable diagnosis of PM. For 126 patients, occupational asbestos exposure (direct, indirect or only presence in the workplace) was identified on average 40 years before diagnosis. In particular, asbestos exposure was documented in shipyards, docks and cargo handling settings, building trades, iron and steel industries. Interestingly, during the same period (1955-1960), a large fraction of subjects without proved or declared direct asbestos exposure claimed to have worked in the same occupational settings. This suggests a possible unconscious indirect exposure to asbestos fibers in the workplace.

A phase II study of a three-drug combination (cisplatin, ifosfamide and vinorelbine) plus granulocyte-colony stimulating factor in advanced non small cell lung cancer.

Twenty-nine patients with advanced non-small-cell lung cancer (NSCLC) were treated with a combination of cisplatin 20 mg/m2 days 1-3, ifosfamide 1500 mg/m2 days 1-2 (plus mesna as uroprotector) and vinorelbine 25 mg/m2 days 1 and 5; filgrastim was given at the dose of 300 microg subcutaneously from day 8 to day 15. A response rate of 28% was observed. The activity of this combination in an outpatient setting, with acceptable toxicity, has been demonstrated.

Pulmonary tumourlets and microcarcinoids in bronchiectasis.

A 66 year old woman underwent a left lower lobectomy for bronchiectasis. Histology revealed the presence of multiple endocrine lesions, such as neuroendocrine cell hyperplasia, tumourlets and microcarcinoids, which were widespread in bronchi, bronchioles and alveolar tissue. This case confirms the occurrence of neuroendocrine proliferations, in the setting of bronchiectasis, ranging from neuroendocrine cell hyperplasia to carcinoids, and suggests tumourlets as an appropriate model for neuroendocrine lung tumour genesis.

[Mantoux intradermal reaction and lymphocyte populations in asymptomatic HIV-seropositive subjects]. / Intradermoreazione alla Mantoux e popolazioni linfocitarie in soggetti HIV sieropositivi asintomatici.

Individuals who are infected with human immunodeficiency virus (HIV) are at high risk of developing tuberculosis, probably due to the reactivation of latent infection associated with HIV-induced immunosuppression. Tuberculin skin test is the best diagnostic means to assess a previous tuberculous infection, but this test may be falsely negative in HIV seropositive subjects. To assess the validity of a non-reactive tuberculin skin test in asymptomatic HIV seropositive subject, we performed Mantoux test 5 TU, chest x-ray, HIV serologic tests on 141 asymptomatic prisoners. Determination of lymphocyte subsets in HIV seropositive carriers had already been performed. Chest x-ray film showed no pleuro-pulmonary lesion in any subject. We found 101 HIV seronegative subjects (89 men and 12 women; 30 +/- 6 yrs with 18-39 range; 34 Mantoux reactive and 67 non-reactive) and 40 HIV seropositive individuals (30 men and 10 women; 29 +/- 6 yrs with 21-39 range; 7 Mantoux reactive and 33 non-reactive). By subdividing HIV seropositive subjects in two groups (reactive and non-reactive to tuberculin test) a significant decrease of CD 4 lymphocytes and CD 4/CD 8 ratio was found in HIV seropositive/Mantoux non-reactive group, without changes in total lymphocytes and CD 8 subset. We conclude that: 1) a non-reactive tuberculin skin test cannot be confidently explained in asymptomatic HIV seropositive subjects with a T helper lymphocyte count decrease; 2) T helper cells are important to keep alive delayed hypersensitivity reaction.

[Bronchial reactivity and cough due to ACE inhibitors]. / Reattività bronchiale e tosse da ACE-inibitori.

The occurrence of a dry, nonproductive cough during ACE inhibitors therapy has been described in several reports. However, the mechanism of this effect is still unknown. In order to clarify whether ACE inhibitor-induced cough is a symptom of an asthmatic disturbance, six patients (age 54-68) with cough related to captopril or enalapril were rechallenged with ACE inhibitors after an adequate washout period. Baseline airway function and bronchial reactivity to metacholine were measured at the end of the washout period and on the fourth day of rechallenge which was accompanied by the reappearance of cough without wheezing. Rechallenge did not cause changes in dynamic lung function; a low and not significant (p less than 0.1) increase in metacholine dose causing a 15% and a 20% reduction in baseline FEV 1 was observed. It is concluded that cough and bronchoconstriction are likely to be mediated through different nervous pathways and that ACE inhibitor-induced cough is not a variant of asthmatic cough.

Pneumoconiosis (silicosis) in the confectionery industry.

Pneumoconiosis is not reported in food industry workers, and more specifically in the confectionery industry. We diagnosed diffuse pulmonary interstitial nodular fibrosis due to inhalation of powder containing quartz in a 54 year-old asymptomatic woman. Silicosis was due to a 5-year period of talc dust exposure 35 years earlier in the confectionery industry. The diagnosis was supported by a history of exposure, transbronchial lung biopsy specimen, 67Gallium scan, and CT scan. Our patient had an unusual history of exposure, which was not readily disclosed until the patient's memories, and after consultation with an expert in confectionery techniques, indicated she had been exposed to talc powder during her employment in the confectionery industry.
