The autologous serum skin test (ASST) predicts the response to anti-IgE treatment in Chronic Spontaneous Urticaria patients: a prospective study.

Summary: Background. Chronic spontaneous urticaria (CSU), characterized by recurrent itchy wheals and angioedema for > 6 weeks, is a quite common disease that may heavily impair the quality of life. Omalizumab, an anti-IgE mAb, has much improved the management of CSU but patients' response to the drug may vary and predictive markers are still largely missing. We investigated the predictive value of the autologous serum skin test (ASST) on omalizumab response. Methods. 15 patients with severe CSU eligible for omalizumab treatment were prospectively studied submitting them to ASST and to complete blood count, D-dimer, anti-thyroid peroxidase antibodies, and total IgE measurement before the start of the treatment. Results. 14/15 (93%) responded brilliantly to omalizumab at 3 months assessment. 7 responded in less than 1 month ("early responders") and 7 only after multiple administrations ("late responders"). Of 9 patients scoring positive on ASST, 7 (78%) were late, and 2 (22%) early responders to omalizumab (p = 0.021). Of 6 patients scoring negative on ASST, 5 were early omalizumab responders and 1 did not respond. The PPV and NPV of the ASST for a "late" response to omalizumab were 78% and 100%, respectively. Total IgE were significantly higher in early responders. Conclusions. Although larger prospective studies are needed to confirm these results, this study confirms previous retrospective investigations that the positive ASST appears to predict a slow response to omalizumab in CSU patients.

Evaluation of the PMMA microlens efficiency for the realization of a solar micro-concentrator array.

In order to assess the performance of solar micro-concentrators, specific methods and protocols need to be developed, tested, and applied. In detail, as in conventional concentration modules, one of the fundamental parameters to consider is the efficiency of optical concentrators. In fact, optical concentrators give fundamental information on the current potentially generated from solar microcells that receive the concentrated light radiation. To develop a measurement method for micrometer-size optical components, a suitable optical system was implemented and used. Moreover, the potential application of the printed microstructures in an optical system for solar micro-concentrators was demonstrated.

The course of language functions after temporal lobe epilepsy surgery: a prospective study.

BACKGROUND AND PURPOSE: Anterior temporal lobectomy (ATL) within the language-dominant hemisphere can impair naming. This prospective study examined the pre-operative to post-operative course of different language components, clarifying which changes are relevant within the short-term and long-term outcome of language. METHODS: Patients with drug-resistant temporal lobe epilepsy (TLE) were evaluated using the Token, Boston Naming and Word Fluency tests assessing sentence comprehension and word-finding on visual, semantic or phonemic cues. RESULTS: A total of 106 patients were evaluated before and 6 months, 1 and 2 years after ATL; 60 patients were also evaluated after 5 years and 38 controls were assessed at baseline. Seizure outcome was comparable between the left and right TLE patients. Before surgery, naming and word fluency were impaired in the left and right TLE patients, whereas sentence comprehension was normal. After left or right ATL, word fluency progressively improved, naming showed early worsening and late improvement after left ATL and progressive improvement after right ATL, and sentence comprehension did not change. At the 5-year follow-up, naming improvement was clinically significant in 31% and 71% of the left and right TLE patients, respectively. Pre-operative naming, ATL laterality, schooling, and post-operative seizure frequency and number of antiepileptic drugs predicted post-operative naming. Pre-operative word fluency and schooling predicted post-operative word fluency. CONCLUSIONS: Left or right TLE can impair word-finding but not sentence comprehension. After ATL, word-finding may improve for a long time, depending on TLE laterality, seizure control and mental reserve. These findings may clarify prognosis prior to treatment.

Graded-size microlens array by the pyro-electrohydrodynamic continuous printing method.

In the present work, the pyro-electrohydrodynamic technique was used for the realization of tunable-size microlens arrays. Poly(methyl methacrylate) dissolved in different solvent mixtures was used as the polymeric material for the realization of the microstructures. By controlling the experimental parameters and in particular, the volume of the drop reservoir, graded-size square arrays of tens of microlenses with focal length in the range 1.5-3 mm were produced. Moreover, the optical quality and geometrical features were investigated by profilometric and interferometric analysis.

Caries prevalence and molar incisor hypomineralisation (MIH) in children. Is there an association? A systematic review.

AIM: Molar incisor hypomeralisation (MIH) is a dental condition clinically characterised by the presence of morphological and qualitative enamel defects involving the occlusal and/or incisal third of one or more permanent molars or incisors. Its worldwide prevalence ranges between 2.4 and 40%. Several harmful conditions, such as genetic or medical problems during pregnancy, may act together and increase the risk of MIH. The main objective of this systematic review is to assess whether there is a correlation between MIH and dental caries in mixed or permanent dentition. METHODS: An electronic search was performed on PubMed (Medline), Scopus and Cochrane Library for articles published from August 2022 to April 2023. Cohort, cross-sectional, retrospective and prospective studies were included. In vitro and animal studies, as well as clinical cases and systematic reviews, were excluded. Studies not differentiating between mixed and permanent dentition were excluded. The observed variables were DMFT (Decayed Missed Filled Teeth) score, DMFS (Decayed Missed Filled Surface) and DMF scores related to FPM (First Permanent Molar) and the clinical prevalence of MIH. CONCLUSION: DMFT, DMFS and DMFT on FPM scores are significantly different between the group of patients with MIH and the control group. The available evidence supports a correlation between MIH lesions and caries. Caries indexes scores increase proportionally to the severity of MIH.

Printing of polymer microlenses by a pyroelectrohydrodynamic dispensing approach.

The investigation of a method for fabricating microlenses by a nozzle-free inkjet printing approach is reported. The new method, based on a pyroelectrohydrodynamic mechanism, is also able to dispense viscous liquids and to draw liquid phase drops directly from the reservoir. Specifically, by dispensing optical grade polymer dissolved in different solvent mixtures, microlenses were printed with a pattern defined directly through this deposition method. The reliability of the microlenses and the tunability of their focal properties were demonstrated through profilometric and inteferometric analyses.

Spoilage-related microbiota associated with chilled beef stored in air or vacuum pack.

In order to study the spoilage-related microbiota of beef at species level, a combination of culture-independent and culture-dependent methods was used to analyse nine different beef samples stored at 4°C in air or in vacuum pack. Plate counts on selective agars after 0, 7 and 20 days of storage showed that vacuum packaging reduced the viable counts of Brochothrix thermosphacta, Pseudomonas spp. and Enterobacteriaceae, whereas the growth of lactic acid bacteria (LAB) was unaffected. Storage in vacuum pack mainly affected viable counts and not necessarily the species diversity of microbial populations on meat. Such populations were studied by PCR-DGGE of DNA directly extracted from meat and from bulk cells from culture media, followed by sequencing of DGGE fragments. Pseudomonas spp., Carnobacterium divergens, B. thermosphacta, Rahnella spp. and Serratia grimesii, or close relatives were detected in the meat at time zero. The use of the culture-independent method highlighted the occurrence of species that were not detected by plating. Photobacterium spp. occurred in most meat samples stored in air or in vacuum pack, which indicates this organism probably has a role in spoilage. In contrast, culture-dependent analysis allowed detection of bacterial species that were not found in DNA extracted directly from meat. This was the case for several species of Serratia or Rhanella among the enterobacteria, and Leuconostoc spp. among the LAB. Besides advancing our knowledge of the species involved in the spoilage of vacuum-packaged meat, this study shows the benefits of combining culture-based and direct approaches to enhance understanding of populations of spoilage bacteria.

Shelf life prediction of fresh Italian pork sausage modified atmosphere packed.

The shelf life of fresh Italian pork sausages packed in modified atmosphere was studied. Samples were packed using different levels of oxygen (high and low) with different levels of carbon dioxide (high-low) in the atmospheres headspace and were stored at 4 °C for 9 days. Microbial, physiochemical and sensory parameters were analyzed during storage. A consumer test was performed to determine the critical acceptability levels. Sensory data were mathematically modelled to estimate product shelf life. A first-order kinetic model and a Weibull-type model aptly described, respectively, the changes in fresh pork sausage odor and color over storage time. These models may be used to predict the sensory shelf life of fresh pork sausage. Results showed that 20% O(2) and 70% CO(2) extend fresh pork sausage shelf life to 9 days at 4 °C. The microbial quality of the samples at the critical sensory level of acceptability was within the range of microbial acceptability.

Captopril increases the intensity of monocyte infection by Trypanosoma cruzi and induces human T helper type 17 cells.

The anti-hypertensive drug captopril is used commonly to reduce blood pressure of patients with severe forms of Chagas disease, a cardiomyopathy caused by chronic infection with the intracellular protozoan Trypanosoma cruzi. Captopril acts by inhibiting angiotensin-converting enzyme (ACE), the vasopressor metallopeptidase that generates angiotensin II and promotes the degradation of bradykinin (BK). Recent studies in mice models of Chagas disease indicated that captopril can potentiate the T helper type 1 (Th1)-directing natural adjuvant property of BK. Equipped with kinin-releasing cysteine proteases, T. cruzi trypomastigotes were shown previously to invade non-professional phagocytic cells, such as human endothelial cells and murine cardiomyocytes, through the signalling of G protein-coupled bradykinin receptors (B(2) KR). Monocytes are also parasitized by T. cruzi and these cells are known to be important for the host immune response during infection. Here we showed that captopril increases the intensity of T. cruzi infection of human monocytes in vitro. The increased parasitism was accompanied by up-regulated expression of ACE in human monocytes. While T. cruzi infection increased the expression of interleukin (IL)-10 by monocytes significantly, compared to uninfected cells, T. cruzi infection in association with captopril down-modulated IL-10 expression by the monocytes. Surprisingly, studies with peripheral blood mononuclear cells revealed that addition of the ACE inhibitor in association with T. cruzi increased expression of IL-17 by CD4(+) T cells in a B(2) KR-dependent manner. Collectively, our results suggest that captopril might interfere with host-parasite equilibrium by enhancing infection of monocytes, decreasing the expression of the modulatory cytokine IL-10, while guiding development of the proinflammatory Th17 subset.

Intraoperative microrecordings in the posterior hypothalamus of anaesthetized humans with aggressive behaviour.

Two patients with uncontrollable aggressive behaviour underwent the placement of stimulating leads in the posterior hypothalamus (pHyp). One patient had also multifocal refractory epilepsy. Microrecordings were obtained in both patients during surgery under general anaesthesia. Firing rate, interspike intervals and oscillatory discharge patterns were analysed in 14 neurons. A mean discharge rate of 19 Hz, and oscillatory activity at 7-8 Hz were recorded in the first patient with aggressiveness and epilepsy. In the second patient the mean firing rate was 10 Hz, with evidence of both tonic and random firing patterns. Previous studies in patients with cluster headache showed that a discharge rate around 20 Hz and lack of a specific rhythmic pattern were the most consistent characteristics of neuronal discharge in this area. Our present findings therefore would suggest that the pattern of discharge of neurons in the pHyp should be evaluated with reference to the presence of concurrent pathology.

Surface ruptures database related to the 26 December 2018, MW 4.9 Mt. Etna earthquake, southern Italy.

We provide a database of the surface ruptures produced by the 26 December 2018 Mw 4.9 earthquake that struck the eastern flank of Mt. Etna volcano in Sicily (southern Italy). Despite its relatively small magnitude, this shallow earthquake caused about 8 km of surface faulting, along the trace of the NNW-trending active Fiandaca Fault. Detailed field surveys have been performed in the epicentral area to map the ruptures and to characterize their kinematics. The surface ruptures show a dominant right-oblique sense of displacement with an average slip of about 0.09 m and a maximum value of 0.35 m. We have parsed and organized all observations in a concise database, with 932 homogeneous georeferenced records. The Fiandaca Fault is part of the complex active Timpe faults system affecting the eastern flank of Etna, and its seismic history indicates a prominent surface-faulting potential. Therefore, this database is essential for unravelling the seismotectonics of shallow earthquakes in volcanic areas, and contributes updating empirical scaling regressions that relate magnitude and extent of surface faulting.

Cardiopulmonary response to exercise in patients with different degrees of lung toxicity after radio-chemotherapy for Hodgkin's disease.

The combination of mediastinal radiotherapy (RT) and polychemotherapy (CT) regimens can produce late toxic pulmonary and cardiac effects which often remain at the subclinical level. The aim of the present study was to investigate the cardiopulmonary response to exercise in this kind of patient. Therefore, 126 patients suffering from Hodgkin's disease were investigated after a follow-up of at least 5 years from the completion of the combined treatment. Sixty-two patients had been submitted to ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine)-RT, 40 to ABVD-MOPP (mechloretamine, vincristine, procarbazine, prednisone)-RT and 24 to VEBEP (vincristine, epidoxorubicin, bleomycin, cyclophosphamide, etoposide, prednisone)-RT. The patients were divided into three groups on the basis of respiratory function: group 1 (67 patients), normal spirometry and lung transfer function for carbon monoxide (DLCO); group 2 (52 patients), normal spirometry and DLCO less than 80% of predicted; and group 3 (7 patients), total lung capacity and DLCO less than 80% of predicted. The patients were submitted to respiratory function evaluation and 2D-echocardiography before exercise, and to the determination of cardiac output by the acetylene rebreathing method before and during symptom-limited exercise on a cycloergometer using an incremental protocol. The patients of group 3 and to a lesser extent the patients of group 2 showed, in comparison to patients of group 1, a lower tolerance to exercise, a lower oxygen consumption, a higher respiratory rate, a lower O2 pulse and a lower cardiac output per oxygen uptake. These data indicated an abnormal exercise physiology in the patients with persistent pulmonary impairment, especially when the reduction of DLCO was associated with a decrease of total lung capacity. The lower exercise capacity seems to be due to a combination of decreased cardiac performance and an impairment of gas diffusion capacity.

Correlation between complication rate and perioperative risk-factors in superior pedicle reduction mammaplasty: our experience in 127 patients.

Reduction mammaplasty, one of the most common plastic surgery procedures, has been shown to confer significant sustained health benefits for patients with symptomatic breast enlargement providing a remedy for back, neck, and shoulder pain. Unfortunately, operations of breast reduction may lead to patient dissatisfaction for poor aesthetic outcome due to complications. Complications, including infection, hematoma, seroma, dehiscence, fat necrosis, and skin loss, may occur in as many as 50% of patients. Unacceptable scarring has also been reported. Complication data revealed several significant features, although there isn't much objective evidence to support that. Over the period 2004-2008, 127 consecutive patients were admitted for breast reduction surgery, data have been analyzed retrospectively to determine whether any correlation could be found between complication rate and perioperative risk-factors using a multifactorial ANOVA F-test. Analysis of variables associated with complications showed that, after adjusting for age and smoking status, only BMI was associated with any complication (p < 0.05). By power analysis, based on a comparison of three proportions, a power of 92% with a significance level of 0.05 was found for the hypothesis that the outcomes of the procedures depends on BMI.

Isolation of Saccharomyces cerevisiae strains from different food matrices and their preliminary selection for a potential use as probiotics.

AIMS: To isolate acid- and bile-resistant Saccharomyces cerevisiae strains directly from food samples and to preliminarily select them on the basis of fundamental probiotic properties. METHODS AND RESULTS: A rapid screening method allowed the isolation and selection of 20 acid- and bile-resistant yeasts from foods, avoiding time-consuming isolation steps. The strains were characterized for their specific survival in simulated gastric juice and in intestinal fluid after pre-exposure at low pH. Ten isolates demonstrated a satisfactory survival percentage in intestinal fluid after pre-exposure to gastric juice and appreciable lipolytic and proteolytic properties, as demonstrated by the API-ZYM test. By using molecular methods five strains were identified as Saccharomyces cerevisiae, three as Candida spp., one as Candida pararugosa and one as Pichia spp. The Saccharomyces cerevisiae strains showed considerable probiotic properties, achieving a 80< % <90 survival through the simulated gastrointestinal tract, as well as interesting glucosidase activities. CONCLUSIONS: The research represents an efficient strategy to select and identify Saccharomyces cerevisiae strains with desirable acid and bile resistances. SIGNIFICANCE AND IMPACT OF THE STUDY: This paper reports the direct selection of potentially probiotic yeasts from foods and provides indications about the ability of Saccharomyces cerevisiae strains to survive conditions simulating the human gastrointestinal tract.

Study of the correlation between sensing performance and surface morphology of inkjet-printed aqueous graphene-based chemiresistors for NO2 detection.

The extremely high sensitivity to the external environment and the high specific surface area, as well as the absence of bulk phenomena that could interfere with the response signal, make graphene highly attractive for the applications in the field of sensing. Among the various methods for producing graphene over large areas, liquid phase exfoliation (LPE) appears to be very promising, especially if combined with inkjet printing (IJP), which offers several advantages, including the selective and controlled deposition of small ink volumes and the versatility of the exploitable inks and substrates. Herein we present a feasibility study of chemiresistive gas sensors inkjet-printed onto paper substrates, in which a LPE graphene suspension dispersed in a water/isopropanol (H2O/IPA) mixture is used as sensing ink. The device performances, in terms of relative conductance variations, upon exposure to NO2 at standard ambient temperature and pressure, are analysed. In addition, we examine the effect of the substrate morphology and, more specifically, of the ink/substrate interaction on the device performances, by comparing the response of different chemiresistors fabricated by dispensing the same suspension also onto Al2O3 and Si/SiO2 substrates and carrying out a supportive atomic force microscopy analysis. The results prove the possibility to produce sensor devices by means of a wholly environmentally friendly, low-cost process that meets the requests coming from the increasing field of paper-based electronics and paving the way towards a flexible, green-by-design mass production.

Paclitaxel in metastatic breast cancer: a trial of two doses by a 3-hour infusion in patients with disease recurrence after prior therapy with anthracyclines.

BACKGROUND: To date, anthracyclines are the most active drugs against breast tumors, and the taxane paclitaxel (Taxol) looks very promising. Both classes of drugs are affected by cellular multidrug-resistance mechanisms, and therefore their sequential use raises the possibility of clinical cross-resistance. It is therefore important to assess the activity of paclitaxel in patients with clinical resistance to anthracyclines. PURPOSE: We assessed the safety and efficacy of paclitaxel administered by the logistically convenient 3-hour infusion to breast cancer patients who had disease progression within 12 months since prior therapy with anthracyclines. METHODS: Fifty-one patients with metastatic breast cancer who had all relapsed or whose disease had progressed within 12 months from completion of an anthracycline-containing chemotherapy protocol (six receiving adjuvant therapy, 19 receiving neoadjuvant therapy, and 26 receiving treatment for metastatic disease) were enrolled in this phase II trial from June 1992 to May 1994. After medication to prevent type I acute hypersensitivity reactions, paclitaxel was given intravenously over 3 hours at 175 mg/m2 to the first 15 patients and at 225 mg/m2 to the next 36 patients. The median age was 50 years (range, 31-62 years), and the median Eastern Cooperative Oncology Group performance status was 0 (range, 0-2). RESULTS: Patients received a median of five cycles (range, one to 11 cycles). After initial doses of 175 and 225 mg/m2, paclitaxel could be increased by 25 mg/m2 in 73% and 58% of cycles, respectively. Among 50 assessable patients, seven achieved a complete response and 12 achieved a partial response (response rate, 38% [95% confidence interval = 25%-53%]). The median duration of response was 7 months (range, 4-16 months), and the median time to disease progression for all patients was 5 months. Grade 4 neutropenia occurred in 3% of the cycles and in 12% of the patients and was never associated with fever and infection. Common toxic effects were myalgia and arthralgia (94% of the patients; 4% grade 3), peripheral neuropathy (92% of the patients; 8% grade 3), and alopecia (all patients). Pruritus and neuropathy were significantly more frequent and severe, respectively, with the higher dose (P < .01 by chi 2 test). Frequency and severity of other toxic effects were similar at either starting dose. Ten patients had symptoms of neuro-optic toxicity. Only one patient had a grade 2 hypersensitivity reaction. CONCLUSIONS: Paclitaxel at starting doses of 175 and 225 mg/m2 given as a 3-hour infusion can safely be administered to, and is active in women whose disease has progressed after prior treatment with anthracyclines. There was evidence of increased toxicity at the higher dose but no suggestion of better efficacy. IMPLICATION: Paclitaxel by a 3-hour infusion in combination with doxorubicin should be investigated in patients with metastatic breast cancer. Unless randomized trials demonstrate greater efficacy of the more toxic higher dose, it is suggested that a dose of 175-200 mg/m2 be administered with the 3-hour infusion schedule.

Potential probiotic Lactobacillus strains from fermented sausages: Further investigations on their probiotic properties.

A rational selection of probiotic microorganisms is an important challenge and requires the definition of fundamental information about the physiology and genetics of candidate strains. In this study, selected Lactobacillus (Lact.) strains already characterized in a previous study for their capability to resist low pH and to grow in conditions simulating the intestinal environment, were further investigated to explore their probiotic properties, such as the adhesion capability to intestinal human Caco-2 cell lines and their growth behaviour in the presence of various prebiotic carbohydrates. At first 25 Lactobacillus strains were characterized by pulsed field gel electrophoresis using the endonuclease NotI. Among them, 13 strains belonging to the Lact. plantarum-group were identified at species level by a multiplex PCR assay. Subsequently 11 Lactobacillus strains showing different PFGE restriction pattern and the best acid- and bile-resistances, were chosen to investigate their in vitro adhesion capability to human intestinal epithelial cells and their fermentation properties of five prebiotic substances (FOS, Inulin, IMO, GOS and lactulose) at a concentration of 2%. The 11 strains analysed in this study possessed good adhesion capability to Caco-2 cell layers and, in particular, the eight strains belonging to the Lact. plantarum-group showed the higher final number of viable adhering cells. Moreover a species-related fermentative behaviour was pointed out and the strain Lact. paracasei EL7 was the only one able to grow in the presence of all prebiotics tested. In conclusion the strains of Lactobacillus studied in this research could be further investigated to assess possible in vivo human health benefits.

Paclitaxel by 3-hour infusion in combination with bolus doxorubicin in women with untreated metastatic breast cancer: high antitumor efficacy and cardiac effects in a dose-finding and sequence-finding study.

PURPOSE: To define the maximum-tolerated dose (MTD) and better tolerated sequence of paclitaxel by 3-hour infusion plus bolus doxorubicin (DOX) and to evaluate antitumor efficacy. PATIENTS AND METHODS: Thirty-five women with metastatic breast cancer (dominant visceral metastases in 56%, and involvement of > or = three sites in 67%) who never received chemotherapy of any type were studied. Paclitaxel every 3 weeks (125 mg/m2 starting dose) was increased by 25-mg/m2 steps in subsequent cohorts of patients. DOX (60 mg/m2 fixed dose) was administered 15 minutes before the start of or after the end of paclitaxel for a maximum of eight cycles. Subsequently, patients in continuous response could receive single-agent paclitaxel (175 to 200 mg/m2 every 3 weeks). The drug sequence was alternated in consecutive patients and in the first two cycles. RESULTS: Severe neutropenia that lasted greater than 7 days (n = 4), febrile neutropenia (n = 7) and grade III oral mucositis (n = 6) defined the MTD of paclitaxel at 200 mg/m2 in 34 assessable patients. Grade II peripheral neuropathy occurred in 33% of patients. Six women (18%) developed clinically reversible congestive heart failure (CHF) after a median of 480 mg/m2 total DOX. Drug sequence had no effect on toxicities. High efficacy on all metastatic sites in 32 assessable patients accounted for a 41% complete response (CR) rate (95% confidence interval [CI], 24% to 59%) and 94% overall-response rate (95% CI, 79% to 99%). After a median follow-up of 12 months (range 3 to 18), the median response duration is 8 months (range, 2+ to 18+) for complete responders and 11 months (range 1+ to 15+) for partial responders. CONCLUSION: The rate of CR and incidence of CHF may be an expression of therapeutic and toxic enhancement due to the schedule used in this trial. Until clarification of this possibility, this promising combination should be used in investigational trials.

Long-term results of combined chemotherapy-radiotherapy approach in Hodgkin's disease: superiority of ABVD plus radiotherapy versus MOPP plus radiotherapy.

In an attempt to reduce some of the delayed sequelae associated with combined modality therapy in Hodgkin's disease, we randomly tested stages IIB, IIIA, and IIIB MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) v ABVD (Adriamycin, bleomycin, vinblastine, and dacarbazine). In 232 previously untreated patients, three cycles of either combination preceded and followed extensive irradiation. The complete remission rate was 80.7% following MOPP and 92.4% following ABVD (P less than .02). The 7-year results indicated that ABVD was superior to MOPP in terms of freedom from progression (80.8% v 62.8%; P less than .002), relapse-free survival (87.7% v 77.2%; P = .06), and overall survival (77.4% v 67.9%; P = .03). Moreover, the comparative iatrogenic morbidity showed that irreversible gonadal dysfunction as well as acute leukemia occurred only in patients subjected to MOPP, while cardiopulmonary studies failed to document significant laboratory differences between the two treatment groups. Present findings indicate that ABVD followed by extensive irradiation represents a valid therapeutic alternative to the widely used alkylating agent-containing regimens plus radiotherapy.
