A noninvasive electromyographic study on threshold and intensity of cough in humans.

The assessment of cough threshold and intensity is important in respiratory medicine. We have developed a method for objectively and noninvasively assessing cough threshold and intensity of expiratory muscle efforts in response to inhalation of ultrasonically nebulized distilled water (UNDW). Thirty (83%) out of 36 volunteers studied coughed in response to UNDW inhalation. Cough threshold was taken as the lowest nebulizer output (mL x min(-1)) that induced cough in two challenges performed at a 30 min interval. At threshold level, repeatability of peak and slope of the integrated electromyographic (IEMG) activity of abdominal muscles was evaluated. Short- and long-term repeatability of cough threshold were evaluated in 15 subjects following a 3 h and a 6-9 month interval, respectively. Dose-response relationships between nebulizer outputs and IEMG-related variables were also investigated, as were the correlations between the latter and expiratory flow during voluntary coughing. The median (1st and 3rd quartile) cough threshold value was 0.89 (0.40 and 1.54) mL x min(-1). At threshold level, peak and slope of IEMG activity were highly reproducible. Cough threshold displayed a high degree of short- and long-term repeatability. Peak and slope of IEMG activity displayed a clear trend to increase (p<0.01) following inhalation of progressively higher UNDW outputs. Maximum flow during voluntary coughs of varying intensity correlated with the peak (p<0.05) and, more closely, with the slope (p<0.01) of abdominal IEMG activity. The assessment of cough threshold as well as the evaluation of the intensity of cough efforts by abdominal integrated electromyographic recordings may represent useful and reliable tools for cough research in humans.

[Zinc blood levels in 73 puerperal women. Correlation with obstetric and neonatal complications].

BACKGROUND: Low plasma zinc concentrations in pregnant women have been associated with certain obstetric and foetal complications. However, there is no agreement in previous studies and mediterranean populations have not been extensively studied. METHODS: The plasmatic zinc was tested in 73 mothers, within 24 hours post-partum, in order to evaluate an association between plasmatic zinc and various obstetric and fetal complications. The women were all from the Florence province and were admitted for delivery at the II Maternity Ward of the University of Florence (Third level Center); mothers of twins and foreign mothers were excluded. Subjects were consecutively included in the study. The values pointed out in a control group (n = 28) were compared with the hematic zinc of a) women who delivered by cesarean section (CS) for acute fetal distress or by operative delivery with vacuum extractor (n = 9), b,c) mothers whose children weighted over the 90th (LGA: n = 11) or under the 10th percentile (SGA: n = 13), and d) mothers who delivered prematurely (n = 12). The subjects included in two or more groups, were not considered. RESULTS: The plasmatic zinc of the control group has been significantly higher than that of mothers who delivered by vacuum extractor or by urgent CS (p < 0.0001) and than that of mothers whose newborns were LGA (p < 0.0024). The hematic zinc of the control group is not higher than that of mothers with SGA or premature children. CONCLUSIONS: The conclusions is drawn that even a relative zinc deficiency may negatively potentiate certain obstetric abnormalities in fetal development or in delivering.

Increased mutagen-induced chromosome damage in patients with transformed laryngeal pre-cancerosis.

Factors that contribute to malignant transformation of laryngeal pre-neoplastic lesions remain largely unknown. Potential etiological factors may be related to a genetically controlled sensitivity to environmental carcinogens. In this study, we investigated bleomycin-induced chromosome damage in 15 patients who experienced a malignant transformation of preneoplastic laryngeal lesions during follow-up, as compared with chromosome fragility in 30 historical controls with no progression of keratoses during a 10-year follow-up, in a match-paired analysis. Chromosomal analysis demonstrated higher sensitivity to clastogens in patients with malignant progression of laryngeal pre-neoplastic lesions than that of control patients with no evolution of their original laryngeal keratoses (p = 0.003). Furthermore, among the study patients, chromosome sensitivity was most apparent in non-tobacco users with malignant transformation of laryngeal disease. Our data suggest that subjects with pre-neoplastic laryngeal lesion showing increased susceptibility to carcinogens could be at higher risk for development of laryngeal carcinoma.

Platelet and blood clotting activation in patients with mitral valve prolapse.

In patients with mitral valve prolapse (MVP) a high incidence of valvular abnormalities with a history of previous cerebrovascular disease has been reported and an embolic mechanism has been proposed. Aim of this study is the study of platelet and coagulation activation in patients with MVP. Fifty-four patients affected by MVP (mean age 46 +/- 15 yrs, 22 males, 32 females) and 50 control subjects, age- and sex-matched, were tested for platelet activation [P-selectin and GpIIb-IIIa platelet surface expression at rest and after stimuli by flow cytometric analysis, Beta-Thromboglobulin (TG) and Platelet Factor 4 (PF4) plasma levels by ELISA, platelet-rich-plasma (PRP) and whole blood spontaneous platelet aggregation (SPA)] and for activation of blood coagulation (Prothrombin activation fragment F1+2 plasma levels by ELISA). P-selectin, GpIIb-IIIa expression, Beta-TG, PF4 and SPA were found similar in MVP patients and in controls. However, in patients with severe mitral regurgitation (MR) the percentage of activated platelets which express P-selectin after stimuli was slightly but significantly (p < 0.05) lower in comparison to MVP patients without or with mild to moderate MR and to controls. Moreover, in patients with severe MR F1+2 levels (median 1.6 nmol/L, range 0.6-2.6 nmol/L) were significantly higher (p < 0.001) than both in controls (median 0.95 nmol/L, range 0.2-1.4 nmol/L) and in patients without or with mild to moderate MR (median 1.0 nmol/L, range 0.4-2.3 nmol/L). Our findings suggest that MVP is not responsible per se for blood clotting activation, but in patients with severe mitral insufficiency an increase in thrombin generation can occur. These alterations in hemostatic system may represent a mechanism by which MR increases the risk of thromboembolic events in patients with MVP.

Epithelial ovarian tumors in the reproductive age group: age is not an independent prognostic factor.

BACKGROUND: While ovarian carcinoma is rare in the reproductive age group, these younger patients are known to fare better than the older patients. To determine whether age is an independent prognostic factor, as well as to investigate the clinicopathologic profile and survival rate of young women with ovarian carcinoma, a retrospective analysis in a series of patients aged 40 years or younger was performed. METHODS: We collected data on 74 patients with borderline or invasive ovarian carcinoma treated at the Department of Obstetrics and Gynecology at the University of Florence between 1969 and 1994. The median follow-up was 72 months (range, 11-288 months). To assess the clinicopathologic profile and survival differences according to age, the series was subdivided into "very young" (30 years or younger) and "young" (31-40 years) groups of 34 and 40 patients, respectively. Survival rates (Kaplan-Meier method) were compared by the log rank test. A multivariate analysis (Cox proportional hazards) was used to determine the independent effect of each variable on survival. RESULTS: The overall 5-year and 10-year survival rates were 58.2% and 46.1%, respectively. Several prognostic factors were found significant by univariate analysis, including stage (P < 0.001), grade (P < 0.001), residual disease (P < 0.001), histologic type (P < 0.05), and age (< or = 30 years vs. 31-40 years; P = 0.009). Five year survival rates for the patients age 30 years and younger and patients age 31-40 years were 71.3% and 47.1%, respectively. In the former group, low malignant potential tumors and well differentiated carcinomas were significantly more frequent (68.8% vs. 37.5%; P = 0.01). In the multivariate analysis, only stage (I vs. >I; P = 0.004), grade (0-1 vs. 2-3; P = 0.03) and residual disease (P = 0.02) were found to be significant independent prognostic factors, whereas age (< or = 30 years vs. 31-40 years) yielded no independent information (P = 0.36). CONCLUSIONS: Epithelial ovarian cancer patients age 30 years or younger have a more favorable prognosis because of a higher rate of early stage, low grade tumors. Patients aged 31-40 years also show a more favorable disease profile and clinical outcome, although to a lesser extent, than the average ovarian cancer population. Age does not emerge as an independent prognostic factor for ovarian carcinoma in women younger than 40 years.

[Features and evolution of postoperative pain in patients undergoing thoracotomy].

We examined in this perspective study 30 patients (15 males and 15 females) who undergone classic thoracotomy for lung or mediastinal diseases, without postoperative complications. Intensity and different qualitative components of postoperative pain have been evaluated in the 1st, 3rd, 5th, the day after last pleural drainage removal and 2 months after the operation. All patients answered a schedule adherent to Questionario Italiano del Dolore (QUID). Pain became less intense chiefly with drainage removal with the same time trend for both sex (parallel curves). Pain is probably stronger in women. From a qualitative point of view, the sensorial component is the same in both sexes. Affective and evaluative component is greater in women: in other words, women realize more than men the painful stimulus and are more troubled. A computerized analysis of answers to a questionnaire like QUID or, better, its evolution, may be helpful for a more effective pharmacological choice between pure analgesics, sedative analgesics and ataractic drugs.

["N2" carcinoma of the lung. Therapeutic considerations].

The follow-up of 240 N2 lung cancer cases operated in Thoracic and Cardiovascular Surgery Department of Florence is examined. The analysis is performed in compliance with global survival, "T", histology, therapeutic choices. Global survival is 81% after 6 months, 60% after 1 year, 37% after 2 years, 26% after 3 years, 23% after 4 years, 23% after 5 years. Significative difference on survival does not exist between principal histologic types (squamous, adenocarcinoma, adenosquamous). Raising the "T" survival decreases, but only for adenocarcinoma. Different therapeutic options (only surgery, surgery+radiotherapy, surgery+chemotherapy, surgery+radio and chemotherapy) do not influence the survival in a way statistically significative. From the literature, any certainty about radiotherapy and chemotherapy associated to surgery for N2 lung cancer treatment does not exist at the moment. Thus radical surgery is essential.

Prediction of occult neck metastases in laryngeal carcinoma: role of proliferating cell nuclear antigen, MIB-1, and E-cadherin immunohistochemical determination.

The aim of this study is to investigate the predictive value of proliferative activity assessment and E-cadherin expression by means of immunohistochemistry in identifying patients with laryngeal squamous cell carcinoma at a high risk for occult node metastasis. Thirty consecutive patients treated for laryngeal carcinoma with false clinically negative nodes (occult metastases, pN+) between the years 1980 and 1990 were selected for this study. A group of 30 cases with negative cervical lymph nodes (pN-) having a similar anatomic site and tumor size distribution was used as control. In each case, several histological parameters, including grade, pattern of invasion, number of mitosis (x10 high-power field), tumor inflammatory infiltrate, and tumor sclerosis, were assessed. Proliferative activity was determined using immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and MIB-1. Other putative prognostic factors investigated at the immunohistochemical level were the cell adhesion molecule E-cadherin and two oncoproteins, p53 and c-erbB-2. In pN+ cases, the expression of PCNA and MIB-1 was significantly higher than in the pN- group. Moreover, a significant loss of E-cadherin expression was observed in carcinomas with occult metastases. No differences in p53 and c-erbB-2 oncoproteins were found between pN+ and pN- cases. Among the other pathological parameters examined, only histological grade was significantly associated with the presence of occult metastases, but on multivariate analysis, this relationship was lost. We conclude that PCNA, MIB-1, and E-cadherin are independent predictors of occult nodal disease in laryngeal squamous cell carcinoma, and their immunohistochemical determination could be useful in identifying patients with clinically negative lymph nodes who are at considerable risk for occult metastases and who may benefit from elective neck dissection.

bcl-2 protein expression correlates with recurrence and survival in early stage head and neck cancer treated by radiotherapy.

Inherent cellular radioresistance plays a critical role in the failure of radiation therapy (RT). The proto-oncogene bcl-2 encodes a protein that inhibits apoptosis, a common mechanism of cell death induced by several genotoxic agents, including gamma-radiation. Thus, it is likely that bcl-2 gene expression could be involved in the complex mechanisms of radioresistance in human tumors with some prognostic implications. In this study, we analyzed the predictive relevance of bcl-2 expression on 5-year disease-free and overall survival in patients with early stage squamous cell carcinoma of the head and neck (SCCHN) primary treated with RT. The expression of bcl-2 was analyzed by immunohistochemistry on paraffin-embedded sections from 71 consecutive stage I-II SCCHN patients treated with curative RT. We detected bcl-2 protein in 21% of SCCHN studied. A suggestive association was observed between tobacco exposure and bcl-2 protein expression (P < 0.1); this association was stronger in those patients who failed primary RT (P = 0.03). Moreover, we documented a higher rate of bcl-2 immunoreactive tumors in postirradiated biopsies from relapsed patients than in preirradiated ones (P = 0.03). In both univariate and multivariate analyses, bcl-2 expression was the most important indicator for disease-free survival (P = 0.08 and P = 0.01, respectively) and overall survival (P = 0.004 and P = 0.05) within 5 years of RT. The present study indicates that the proto-oncogene bcl-2 is abnormally expressed in some SCCHN, and its expression may prove to be a useful tool in selecting patients for conventional RT with clear prognostic implications.

p53 oncoprotein expression in parotid gland carcinoma is associated with clinical outcome.

BACKGROUND: Recent studies of the molecular biology of cancer have demonstrated that p53 tumor suppressor gene aberration is associated with the development and progression of several different cancer types. METHODS: To analyze the expression of the p53 oncoprotein in parotid gland neoplasms, 72 parotid gland tumors (including 46 malignant and 26 benign cases) were studied immunocytochemically using the murine monoclonal DO-7 anti-p53 antibody. In parotid gland cancers, no and low expression (-/+) or moderate and high expression (++/+++) of the p53 oncoprotein were examined for correlation with patient survival and other clinicopathologic features, including clinical stage, tumor size, regional lymph node status, facial nerve paralysis, local infiltration, and distant failures. RESULTS: Positive staining was observed focally in 3 of 26 (11%) benign tumors and in 31 (67%) of 46 malignant tumors. Cancers showing moderate and high expression of p53 tended to be more advanced and larger than those with no expression or low expression, and presented at diagnosis more frequently, with signs of local aggressiveness. Tumors with moderate and high expression of p53 were associated more frequently with regional and distant metastases (P = 0.07 and P = 0.004, respectively). Multiple logistic regression analysis showed that regional and distant metastases were associated independently with p53 expression (P = 0.068 and P = 0.047, respectively). Moreover, patients whose cancers had moderate or high p53 expression had lower disease free and overall actuarial survival rates than those with no or low p53 expression (P = 0.021 and P = 0.033, respectively). Univariate and multivariate analysis confirmed the independent predictive prognostic value of p53 expression in patients with parotid gland cancer (P = 0.044 and P = 0.039, respectively). Furthermore, p53 expression did not correlate positively with patients' smoking habits in this series. CONCLUSION: The p53 tumor suppressor gene may be involved in salivary gland carcinogenesis, and its oncoprotein expression is an independent indicator of clinical aggressiveness in patients with carcinoma of the parotid gland.

Prognostic significance of clinically false positive cervical lymph nodes in patients with laryngeal carcinoma.

BACKGROUND: A significant proportion of clinically positive palpable cervical lymph nodes in patients with head and neck cancer are histologically benign. The biologic and prognostic significance of this reactive lymph node enlargement has not been fully clarified. METHODS: In this study, the incidence of clinically positive microscopically negative cervical lymph nodes in a series of 902 patients who had neck procedures as a part of their primary treatment for N0-2 laryngeal cancer was analyzed and survival rates of 342 patients with true negative lymph nodes (N0- necks) were compared with those of 106 patients with clinically false positive lymph nodes (N1-2b- necks). In 86 patients with false positive lymph nodes, a histopathologic analysis was performed to determine the histomorphologic pattern of the enlarged lymph nodes and to evaluate which parameters, if any, correlated with 5-year patient survival. RESULTS: Overall actuarial survival did not differ significantly in the two groups. However, the actuarial survival curves in the false positive group were clearly better compared with those of the true negative group with more advanced laryngeal cancers, particularly T4 lesions (P < 0.05). Interestingly, the analysis of pattern of recurrence showed a higher incidence of distant metastases in false positive patients with advanced stage laryngeal cancer than in true negative subjects. In addition, the histologic examination of 375 enlarged hyperplastic cervical lymph nodes from 86 neck specimens showed the prevalence of sinus histiocytosis in the false positive group and its favorable prognostic significance. No statistically significant differences with regard to the number and size of enlarged lymph nodes were found. On the contrary, lymph node location seems to have a prognostic impact on survival and the reactive benign enlargement of a digastric lymph node is a possible poor prognostic factor. CONCLUSIONS: Survival of patients with clinically false positive, histologically benign hyperplastic cervical lymph nodes who have more advanced laryngeal carcinoma is higher than clinically negative patients, suggesting that the presence of palpable benign nodes may be a sign of the host's immune activation, with favorable prognostic significance.

Cardiovascular function during brain natriuretic peptide infusion in man.

To investigate the cardiovascular effects of pathophysiological levels of brain natriuretic peptide (BNP), 7 healthy subjects were submitted to equilibrium radionuclide angiocardiography in baseline conditions and during BNP infusion at increasing doses (4, 8, 10 and 12 pmol/kg.min for 20 min each). BNP induced a progressive, significant reduction in left ventricular end diastolic volume, stroke volume and end systolic volume and an increase in ejection fraction and heart rate. Cardiac output, arterial pressure and peripheral vascular resistance were unchanged. Activation of the sympathetic nervous system, as indicated by the significant increase in plasma norepinephrine levels, probably played a contributory role in the maintenance of cardiovascular homeostasis. These results indicate that BNP, at pathophysiological plasma concentrations, influences cardiovascular homeostasis in man.

Comparison of dose-response slopes obtained by simultaneous assessment of changes in FEV1 and transcutaneous oxygen partial pressure during methacholine challenges in asthmatic patients.

We aimed to ascertain whether monitoring changes in transcutaneous (tc) oxygen partial pressure (PO2) may be used to determine the slope of the dose-response curves to inhaled methacholine. In 10 adult asthmatic patients, FEV1 and tcPO2 were simultaneously measured during inhalation of doubling methacholine concentrations. In each patient, the slopes of the methacholine dose-response curves for FEV1 and tcPO2 were similar and strongly correlated (r = 0.72; p < 0.05). The results indicate that tcPO2 monitoring represents a useful, reliable tool for analysis of the slope of dose-response curves to inhaled methacholine in asthmatic patients. It can also be used to investigate the pathophysiological implications of bronchial hyperreactivity.

Second solid tumors and leukemia after treatment for Hodgkin's disease: an analysis of 1121 patients from a single institution.

PURPOSE: To define the risk of having a second malignant neoplasm (ST) in different subsets of Hodgkin's disease patients and possibly to identify potentially avoidable therapeutic behaviors, linked with an increased second tumor probability. METHODS AND MATERIALS: Cumulative probability of having a ST has been calculated for the different clinical and therapeutic subgroups of a population of 1121 patients consecutively treated (1960-1988) for Hodgkin's disease. Age groups at diagnosis were as follows: < 20 years, 18%; 20-40, 48%; 41-60, 26%; > 60, 8%. Initial treatment consisted of radiation alone (67%), combined modality treatment (24%), chemotherapy alone (9%). Treatment for relapse was also coded, and the occurrence of ST was related both to initial treatment (considering relapsed patients as censored at relapse) and to the "overall" treatment burden, without censoring at relapse. RESULTS: An increased ST risk has been observed in patients older at HD diagnosis. Second tumors cumulative probability rates were significantly higher in patients initially treated with chemotherapy, especially when associated with subtotal or total nodal irradiation (relative risks of 3.1 and 4.1, p = .03 and .005, respectively, when compared to involved field radiotherapy alone). The same trend was observed for second solid tumors. Acute leukemia was more frequent in patients initially given chemotherapy alone or associated with radiotherapy (p = .01), and in those treated with an increasing number of cycles (p = .004). "Salvage" chemotherapy after radiation alone at presentation does not seem to be linked with an increased risk of leukemia. CONCLUSION: The 15-year cumulative ST probability (11%) should be evaluated in the context of the very good cure rates achieved for Hodgkin's disease. The use of chemotherapy, particularly when associated with subtotal or total nodal irradiation, entails an increased risk of second malignancies and might be inappropriate in early stage Hodgkin's disease patients.

Prognostic value of flow cytometric deoxyribonucleic acid index in endometrial carcinoma: comparison with other clinical-pathologic parameters.

OBJECTIVE: The aims of the current study were to verify the impact of flow cytometric deoxyribonucleic acid index on clinical outcome in endometrial carcinoma and to assess whether its value is independent from the other clinical-pathologic features. STUDY DESIGN: In a prospective series 74 cases of endometrial carcinoma with surgery performed at our institution were studied. Flow cytometry was performed on fresh tumor samples. The median follow-up period was 31 months (range 8 to 52). Disease-free survival and actuarial survival were the end points of the study. RESULTS: Among the 74 patients (53 with diploid and 21 with aneuploid tumors) there were 14 recurrences and 10 deaths caused by the disease. The recurrence rate was 7.5% for the diploid and 47.6% for the aneuploid tumors (p < 0.001). Mortality was 3.8% for diploid and 38% for aneuploid cases (p < 0.001). Disease-free survival was 89.1% in the former group and 36.3% in the latter. Actuarial survival (Kaplan-Meier method) was 94.7% and 49.5%, respectively. Deoxyribonucleic acid index, stage (International Federation of Gynecology and Obstetrics), and grade of differentiation were significantly correlated with survival, whereas age, depth of myometrial invasion, and histologic type were not. In a multivariate analysis (Cox proportional hazards) deoxyribonucleic acid index was the strongest independent predictor of clinical outcome, followed by International Federation of Gynecology and Obstetrics stage, whereas grade of differentiation yielded no independent prognostic information. CONCLUSIONS: The flow cytometric deoxyribonucleic acid index is an important independent prognosticator, and its determination should be included in the standard management of endometrial cancer.

Changes in transcutaneous oxygen partial pressure as an index of response to inhaled methacholine in asthmatic patients.

Bronchoconstriction and hypoxemia have been reported to occur during airway challenges, but the correlation between changes in forced expiratory volume in 1 s (FEV1) and transcutaneous oxygen partial pressure (tcPO2) during methacholine provocation tests has not yet been established (to our knowledge). In 15 symptom-free atopic asthmatic patients and 5 normal subjects, variations in tcPO2 and FEV1 were simultaneously measured during inhalation of doubling methacholine concentrations; the drug concentrations causing a 20 percent decrease in control FEV1 and tcPO2 (PC20FEV1 and PC20tcPO2, respectively) were subsequently calculated. In patients, geometric mean PC20FEV1 and PC20TcPO2 were 1.31 (range, 0.16 to 5.19) and 1.26 (range, 0.29 to 5.82) mg/ml, respectively. In addition, in six patients, methacholine-induced fall in tcPO2 was accompanied by similar changes in arterial PO2. Methacholine inhalation caused no change in tcPO2 or FEV1 in normal subjects. The independent effects of deep breath tests and bronchoconstriction on PC20tcPO2 were studied in five patients challenged on two separate occasions, with and without FEV1 assessment; in these patients, PC20tcPO2 were similar on both the study days. The results indicate that, in asthmatic patients, methacholine-induced bronchoconstriction causes parallel decreases in FEV1 and tcPO2. The tcPO2 monitoring may serve as a tool in the assessment of airway hyperreactivity when active patient's cooperation is scarce.

High-dose aprotinin: hemostatic effects in open heart operations.

Two groups of patients were prospectively studied to evaluate the hemostatic effects of high-dose aprotinin in open heart operations. Group A patients (n = 22) received aprotinin during the entire surgical procedure. Group B patients (n = 12) served as controls. The groups were homogeneous for base variables and for cardiopulmonary bypass duration. Postoperative bleeding was lower in group A (mean, 486 mL) than in group B (830 mL) (p less than 0.01). The need for banked blood decreased by approximately half in the aprotinin patients (mean: group A, 213 mL; group B, 409 mL). Hemoglobin levels were similar in the two groups (postoperative day 7: group A, 11.29 g/100 mL; group B, 11.26 g/100 mL; NS). Platelet count decreased at the end of operation in both groups (99,000 and 95,000/mL, respectively; NS) and then increased beyond baseline levels before discharge. No complications were observed that could be attributed to aprotinin. In conclusion, we believe that the use of high-dose aprotinin is safe and effective. It decreases blood loss and reduces the need for banked blood in cardiac operations, particularly in select groups of patients (eg, those undergoing reoperation, Jehovah's Witnesses, those with renal failure).
