Systematic review of fall risk screening tools for older patients in acute hospitals.

AIMS: To determine the most accurate fall risk screening tools for predicting falls among patients aged 65 years or older admitted to acute care hospitals. BACKGROUND: Falls represent a serious problem in older inpatients due to the potential physical, social, psychological and economic consequences. Older inpatients present with risk factors associated with age-related physiological and psychological changes as well as multiple morbidities. Thus, fall risk screening tools for older adults should include these specific risk factors. There are no published recommendations addressing what tools are appropriate for older hospitalized adults. DESIGN: Systematic review. DATA SOURCES: MEDLINE, CINAHL and Cochrane electronic databases were searched between January 1981-April 2013. Only prospective validation studies reporting sensitivity and specificity values were included. REVIEW METHODS: Recommendations of the Cochrane Handbook of Diagnostic Test Accuracy Reviews have been followed. RESULTS: Three fall risk assessment tools were evaluated in seven articles. Due to the limited number of studies, meta-analysis was carried out only for the STRATIFY and Hendrich Fall Risk Model II. In the combined analysis, the Hendrich Fall Risk Model II demonstrated higher sensitivity than STRATIFY, while the STRATIFY showed higher specificity. In both tools, the Youden index showed low prognostic accuracy. CONCLUSION: The identified tools do not demonstrate predictive values as high as needed for identifying older inpatients at risk for falls. For this reason, no tool can be recommended for fall detection. More research is needed to evaluate fall risk screening tools for older inpatients.

In situ identification of CD44+/CD24- cancer cells in primary human breast carcinomas.

Breast cancer cells with the CD44+/CD24- phenotype have been reported to be tumourigenic due to their enhanced capacity for cancer development and their self-renewal potential. The identification of human tumourigenic breast cancer cells in surgical samples has recently received increased attention due to the implications for prognosis and treatment, although limitations exist in the interpretation of these studies. To better identify the CD44+/CD24- cells in routine surgical specimens, 56 primary breast carcinoma cases were analysed by immunofluorescence and confocal microscopy, and the results were compared using flow cytometry analysis to correlate the amount and distribution of the CD44+/CD24- population with clinicopathological features. Using these methods, we showed that the breast carcinoma cells displayed four distinct sub-populations based on the expression pattern of CD44 and CD24. The CD44+/CD24- cells were found in 91% of breast tumours and constituted an average of 6.12% (range, 0.11%-21.23%) of the tumour. A strong correlation was found between the percentage of CD44+/CD24- cells in primary tumours and distant metastasis development (p = 0.0001); in addition, there was an inverse significant association with ER and PGR status (p = 0.002 and p = 0.001, respectively). No relationship was evident with tumour size (T) and regional lymph node (N) status, differentiation grade, proliferative index or HER2 status. In a multivariate analysis, the percentage of CD44+/CD24- cancer cells was an independent factor related to metastasis development (p = 0.004). Our results indicate that confocal analysis of fluorescence-labelled breast cancer samples obtained at surgery is a reliable method to identify the CD44+/CD24- tumourigenic cell population, allowing for the stratification of breast cancer patients into two groups with substantially different relapse rates on the basis of CD44+/CD24- cell percentage.

Mitoxantrone, carboplatin, cytosine arabinoside, and methylprednisolone followed by autologous peripheral blood stem cell transplantation: a salvage regimen for patients with refractory or recurrent non-Hodgkin lymphoma.

BACKGROUND: The objective of the current study was to evaluate a salvage chemotherapy regimen consisting of mitoxantrone, carboplatin, cytosine arabinoside, and methylprednisolone (MiCMA) for the treatment of patients with primary refractory or recurrent non-Hodgkin lymphoma (NHL). METHODS: From September 1991 to August 2002, 94 consecutive patients ages 16-60 years who had either recurrent or refractory NHL (mainly diffuse large-cell lymphomas) were treated on the MiCMA protocol. Patients had peripheral blood stem cells collected successfully for autologous stem cell transplantation after two or three cycles of MiCMA. RESULTS: Sixty-four of 85 evaluable patients achieved a response to the MiCMA regimen: 24 patients (26%) achieved a complete response and 40 patients (44%) achieved a partial response, for a total response rate of 70%. Sixty-two patients underwent autologous stem cell transplantation. After a median follow-up of 58 months, 47 patients (55%) remained alive; among these patients, 32 were free of disease (37%). No toxic deaths related to MiCMA were observed. Three patients died of infectious complications after transplantation. CONCLUSIONS: The current results suggested that MiCMA chemotherapy is an effective therapeutic alternative salvage regimen for patients with primary refractory or recurrent NHL. Response rates, overall survival, and freedom from disease progression were found to be associated significantly with response to MiCMA. Peripheral blood stem cell transplantation was feasible in virtually all patients, and its outcome was influenced strongly by chemosensitivity.

The role of GPs in increasing compliance to colorectal cancer screening: a randomised controlled trial (Italy).

AIMS: To assess the effect of the provider (GPs versus hospital) on the compliance in returning the faecal occult blood test. To analyse the characteristics of the GP associated with high compliance among his beneficiaries. METHODS: A questionnaire about screening attitudes was mailed to the 1192 GPs working in 13 districts of the Lazio region. We asked the GPs to participate in a randomised trial, we sampled 130 GPs and about 1/10 of the GPs' 50-75 year old beneficiaries (n = 3657) were invited to be screened at the GP office and 1/10 (3675) at the nearest gastroenterology centre. RESULTS: 58.5% of the GPs completed the questionnaire and 22.7% agreed to participate in the trial. The compliance in the GP arm was 50%, in the hospital arm 16% (RR 3.4; 95% CI: 3.13-3.70). There was a high variability in the compliance obtained by the GPs. GPs with more than 25 patients visited/day and those incorrectly recommended screening of colorectal cancer obtained a lower compliance (OR 0.74, 95% CI: 0.57-0.95 and OR 0.76, 95% CI: 0.59-0.97, respectively). CONCLUSIONS: The involvement of GPs in colorectal cancer screening can be very effective to enhance the compliance, but the effectiveness is dependent on their willingness to be involved.

Cardiac circumference measurement: possible screening tool in early pregnancy for anomalous cardiac development.

OBJECTIVE: In this study, cardiac circumference (CC), measured by transvaginal sonography, was analyzed to determine the growth during the early stage of pregnancy and its relationship to abdominal circumference and femur length (FL). METHODS: Biometric measurements, including CC, were obtained in 1,182 euploid fetuses at 9-16 weeks' gestation. The CC measurements were related to gestational age (GA), abdominal circumference, and FL. The corresponding 95% confidence intervals were calculated. RESULTS: A linear growth function was observed between CC (mm) and GA (days) (r2 = 0.601; p < 0.0001; y = 0.573 GA - 24.185). Similarly, a good correlation is described with a linear function between CC (mm) and abdominal circumference (mm) (r2 = 0.70; p < 0.0001; y = 0.343 AC + 3.696) and between CC (mm) and FL (mm) (r2 = 0.626; p < 0.0001; y = 1.335 FL + 14.444). The regression analysis that best correlates the dependent variable CC (mm) with the independent variables, GA (days), abdominal circumference (mm), and FL (mm), is: y = 0.137 GA + 0.235 AC + 0.199 FL - 3.303 (r2 = 0.708; p < 0.0001). CONCLUSION: Our results provide normative data of the growth of the CC in early pregnancy. The good correlation described between CC and abdominal circumference and FL suggests that cardiac measurements in early pregnancy alone, or related to other fetal biometric parameters, could be used as a screening tool to identify fetuses at risk for abnormal heart development.

Understanding non-compliance to colorectal cancer screening: a case control study, nested in a randomised trial [ISRCTN83029072].

BACKGROUND: The major limit to colorectal cancer screening effectiveness is often low compliance. We studied the reasons for non compliance and determinants of compliance to faecal occult blood tests in Lazio, Italy. METHODS: This is a case-control study nested within a trial that tested the effect of type of test and provider on colorectal cancer screening compliance. Non compliant trial subjects were classified as cases, and compliant subjects were classified as controls. We sampled 600 cases and 600 controls matched by their general practitioner, half were invited for screening at the hospital, and the other half directly at their general practitioner's office. Cases and controls answered questions on: distance from test provider, logistical problems, perception of colorectal cancer risk, confidence in screening efficacy, fear of results, presence of colorectal cancer in the family, and gastrointestinal symptoms. RESULTS: About 31% of cases never received the letter offering free screening, and 17% of the sampled population had already been screened. The first reported reason for non-compliance was "lack of time" (30%); the major determinant of compliance was the distance from the test provider: odds ratio > 30 minutes vs < 15 minutes 0.3 (95% CI = 0.2-0.7). The odds ratio for lack of time was 0.16 (95% IC 0.1-0.26). The effect was stronger if the hospital (0.03 95% CI = 0.01-0.1) rather than the general practitioner (0.3 95% CI = 0.2-0.6) was the provider. Twenty-two percent of controls were accompanied by someone to the test. CONCLUSION: To increase compliance, screening programmes must involve test providers who are geographically close to the target population.

Can 13C urea breath test predict resistance to therapy in Helicobacter pylori infection?

BACKGROUND/AIMS: Results of 13C urea breath test (UBT), a noninvasive test for detecting active H. pylori infection, have been regarded also numerically for a possible predictive value on bacterial load and entity of mucosal inflammation. In the present study we wished to determine whether there is a particular value of Delta Over Baseline (DOB) result which could predict resistance to anti-H. pylori therapy. METHODOLOGY: 570 subjects from 1376 tested received a standard triple anti-H. pylori regimen. After a minimum of 6 weeks subjects underwent control UBT testing. Correlation of DOB values at diagnostic and control UBT and sensitivity of different DOB levels to predict resistance to therapy were calculated using simple linear correlation and Bayes' theorem, respectively. RESULTS: Modest linear correlation was observed between DOB values (r2=0.28). The value of 13.0 at diagnostic UBT showed a sensitivity of 65.5% to predict and further positivity at control testing. CONCLUSIONS: In our large series, UBT numerical DOB value weakly predicted resistance to first-line anti-H. pylori therapy.

The immunochemical faecal occult blood test leads to higher compliance than the guaiac for colorectal cancer screening programmes: a cluster randomized controlled trial.

INTRODUCTION: We conducted a cluster-randomized trial aimed at assessing the effect of the type of faecal occult blood, guaiac or immunochemical test on screening compliance. METHODS: We sampled 130 general practitioners (GPs) who consented to participate in the trial. We randomly allocated half of them to the guaiac (Hemo-Fec) and half to the immunochemical test (OC-Hemodia). We sampled 2/10 of the GPs' 50-75-year-old patients (n=7332) and randomly divided this population into half. One half was invited to be screened at the GP's office and the other to the nearest gastroenterology ward. The principal outcome was the percentage of returned tests. RESULTS: The immunochemical test had a compliance of 35.8% and the guaiac of 30.4% (relative risk [RR] 1.20; 95% confidence interval [CI] 1.02-1.44). The difference was mostly due to a higher probability of returning the sample: 93.8% and 88.6% for immunochemical and guaiac, respectively (RR 1.06; 95% CI 1.02-1.10). The guaiac test had a higher prevalence of positives (10.3% versus 6.3%, RR 0.603; 95% CI 0.433-0.837). There was a higher variability in the results obtained with the guaiac test compared with the immunochemical (F[1, 12] = 16.25; P=0.0017). CONCLUSIONS: Compliance is more likely with the immunochemical than the guaiac test, independent of the provider. Guaiac tests show a higher variability of the results among centres. The successful implementation of a screening programme requires a period of standardization of the test reading in order to avoid unexpected work overload for colonoscopy services.

Survey on colorectal cancer screening knowledge, attitudes, and practices of general practice physicians in Lazio, Italy.

BACKGROUND: Several international guidelines have recommended the involvement of general practitioners (GPs) in screening programs, but current evidence suggests this is very difficult. We implemented a survey to understand the attitudes, knowledge, and practices regarding colorectal cancer screening of GPs in the Lazio region. METHODS: Survey of all GPs working in 13 of the 50 districts in Lazio using a mail-in questionnaire. RESULTS: Out of 1192 GPs, 699 responded (59%). Ninety-four percent consider CRC a preventable disease. Knowledge about oncological screenings is higher in GPs using the guidelines as source of information. Twenty-five percent properly recommend the available screening tests for colorectal cancer, 22% do not recommend any, 6% under-recommend, and 47% over-recommend. Adequate knowledge of oncological screenings is positively associated with correct recommendation. Thirty-two percent of GPs recommend inappropriate follow-up tests for patients with positive fecal occult blood test. CONCLUSIONS: The low response rate reveals the lack of GP's interest in screening. Knowledge about screening and use of guidelines as sources of scientific information are important factors to improve attitudes about screening, but there is a large percentage of well-informed GPs who do not recommend colorectal cancer screening at all. Currently, many GPs do not properly follow the patients up after a positive FOBT.

Trying to improve the compliance to colorectal cancer screening: a complex study design for a complex planning question.

The efficacy of faecal occult blood test as primary screening for colorectal cancer has been demonstrated. Screening programs, to be effective, should guarantee high compliance in the target population. The aim of this paper is to describe the design of three connected studies aimed at obtaining precise indications for planning a colorectal cancer screening program with high compliance. We designed a survey, with a randomised controlled trial nested within it, and a case-control study nested within that and defined by the results of the trial. The complex interconnection of studies reflects the aim to produce indications for an evidence-based planning of a public health program, which is itself, a complex phenomenon. The trial was designed to evaluate two different types of tests, Immunochemical and Guaiac, and two different providers, general practitioner and hospital, with a 2 x 2 factorial design. The randomization was performed at two different levels to minimize the loss of power: at the practice level for test type (cluster randomisation) and individual level for provider type.

Predictive factors of renal involvement or relapsing disease in children with Henoch-Schönlein purpura.

Predictive factors of renal involvement or relapsing disease in children with Henoch-Schönlein purpura (HSP) are poorly known. We examined clinical and laboratory variables concerning HSP evolution in children hospitalized in the last decade to predict the possibility of renal complications or relapse occurrence. Periodic clinical evaluations with urinalysis were performed for 6 +/- 3.6 years. Simple logistic regression showed that persistent rash and severe abdominal pain at the onset of HSP are significantly related to renal involvement, while persistent rash is significantly related to relapsing disease. Multiple logistic regression showed that persistent rash remains related to renal involvement when adjusted for sex, age, and severe abdominal pain and conversely that severe abdominal pain is not related to renal involvement when adjusted for sex, age, and persistent rash. In conclusion, persistent rash over a period longer than 1 month seems to represent a significant predictor of renal sequelae and disease relapse in children with HSP.

Specific ultrarush desensitization in Hymenoptera venom-allergic patients.

BACKGROUND: Hymenoptera venom hypersensitivity is an epidemiologically important problem. The only effective treatment in the management of venom-allergic patients with a history of generalized reactions to insect sting is specific immunotherapy. OBJECTIVE: To demonstrate safety and effectiveness of a modified ultrarush desensitization protocol in venom-allergic patients. METHODS: Fifty-seven patients with Hymenoptera venom allergy underwent a specific 1-day ultrarush desensitization by the subcutaneous route, reaching the cumulative dose of 101.1 microg in 2.5 hours. The maintenance dose (100 microg) was administered after 15 days and thereafter once a month. Patients were followed up for a year. Antihistamines were withheld for 15 days before and during desensitization to not underestimate the incidence of adverse effects. RESULTS: All patients but I completed the ultrarush desensitization. (This patient discontinued the treatment because of a hypertensive crisis not related to the desensitization.) The treatment caused a rapid variation of immunological parameters (IgE, IgG4) since the 15th day. After the desensitization, skin prick test results became negative in 15 patients (27%, decrease of 3.5 log), whereas they decreased in 14 patients (25%, decrease of 1 log). Sixty-four percent showed no adverse effects. Only 7% had a mild systemic reaction. CONCLUSIONS: Ultrarush desensitization is an effective and safe therapy in the management of patients with Hymenoptera venom allergy. In fact, it provides a faster tolerance, without significant differences regarding incidence of severe adverse effects, compared with traditional and rush protocols. It can be adopted for all patients, even children and teenagers.

Methylenetetrahydrofolate reductase genotypes do not play a role in acute lymphoblastic leukemia pathogenesis in the Italian population.

BACKGROUND AND OBJECTIVES: Methylenetetrahydrofolate reductase (MTHFR) is one of the enzymes involved in folate metabolism and DNA methylation and synthesis. Some genotypes of this highly polymorphic enzyme are associated with decreased activity. Previous studies have suggested that individuals with the MTHFR 677TT, 1298AC and 1298CC have a lower risk of adult acute lymphoblastic leukemia (ALL). DESIGN AND METHODS: In order to test this association we studied the presence of the C677T and A1298C mutant alleles in 174 patients with acute lymphoblastic leukemia and in 110 controls from central Italy. RESULTS: We did not find any association between the different polymorphisms and susceptibility to ALL. In multivariate analysis different genotypes did not show any correlation with the risk of ALL. The adjusted odds ratios and 95% confidence intervals for MTHFR C677T were 0.69 (0.4-1.19) for 677CT versus 677CC wild type, and 0.99 (0.50-1.97) for 677TT versus 677CC. The corresponding values for MTHFR A1298C were 0.93 (0.56-1.53) for 1298AC versus 1298AA wild type and 1.14 (0.36-3.61) for 1298CC versus 1298AA. INTERPRETATION AND CONCLUSIONS: These results do not support the suggestion that populations carrying different genotypes of the two MTHFR polymorphisms, C677T and A1298C, have a different susceptibility to ALL, at least in the Mediterranean area.

Gastric surgery as a long-term risk factor for malignant lesions of the larynx.

BACKGROUND: Duodenogastroesophageal reflux is common after total or partial gastrectomy. No data are available on the effect of duodenal reflux on the larynx. HYPOTHESIS: Premalignant or malignant changes occur more frequently among subjects with gastric surgery. DESIGN: Historical cohort study. SETTING: Outpatient setting for upper endoscopy. PATIENTS: Ninety-three subjects who had undergone gastric resection at least 5 years previously, and 93 matched dyspeptic individuals who did not undergo gastric surgery. INTERVENTION: Clinical histories of all patients were obtained and recorded. All subjects underwent an otolaryngologic evaluation. RESULTS: Of 93 patients with gastric resection, 7 patients had current or previous laryngeal malignancies or current precancerous mucosal changes. In the control group, 1 subject had a leukoplakia on the vocal cord. The adjusted odds ratio (having included sex, age, and alcohol [yes or no] and smoking [yes or no] history in the regression model) was 9.88 (95% confidence interval, 1.01-97.31; likelihood ratio chi2 = 28.77; P<.001). Furthermore, there was a significant increased prevalence of benign laryngeal lesions in patients with gastric resection vs the control group. CONCLUSIONS: The risk of developing laryngeal malignancies is higher for patients with gastric resection. A periodic otolaryngologic evaluation in subjects with gastric surgery may contribute to early diagnosis of laryngeal disorders.

Helicobacter pylori, gastrointestinal symptoms, and metabolic control in young type 1 diabetes mellitus patients.

OBJECTIVE: The role of Helicobacter pylori infection in metabolic control and gastrointestinal symptoms in type 1 diabetes mellitus (DM1) patients has been debated. The aim of this study was to investigate the prevalence of H pylori, of the more cytotoxic Cag-A-positive strains, and the effects of infection on gastrointestinal symptoms and metabolic control in young DM1 patients. Research Design and Methods. H pylori infection was investigated by using the 13C-urea breath test in 121 DM1 patients (65 males, 56 females; mean age: 15 +/- 6 years) and 147 matched controls. In positive patients, an assay for specific immunoglobulin G against Cag-A was performed. Glycosylated hemoglobin A, daily insulin requirement, and duration of illness were established; a questionnaire concerning the presence of dyspeptic symptoms was administered. RESULTS: No difference in H pylori infection rate between patients and controls was observed. Thirty-four (28.1%) of 121 patients and 43 (29.25%) of 147 controls were infected. Twenty-one patients and 24 controls were positive for Cag-A. Glycosylated hemoglobin A, daily insulin requirement, and duration of illness were not affected by infection nor by Cag-A status. Among gastrointestinal symptoms, only halitosis was related to H pylori infection, but this association disappeared after correction for age. Positive patients with halitosis showed a worse glycemic control than uninfected patients with halitosis. CONCLUSIONS: H pylori infection and Cag-A-positive strains do not affect metabolic control in DM1 patients. With regard to gastrointestinal symptoms studied, H pylori infection, when present in participants with halitosis, seems to predict a worse metabolic control than in H pylori-negative patients with halitosis.

Thrombopoietin serum levels in patients with inflammatory bowel disease with and without previous thromboembolic events.

BACKGROUND/AIMS: Patients affected by inflammatory bowel disease frequently suffer from thromboembolic complications and mesenteric microvascular occlusion could be involved in the pathogenesis of inflammatory bowel disease. Increased platelet counts and abnormal platelet function seem to play a crucial role in determining the hypercoagulable state observed in inflammatory bowel disease. Thrombopoietin is considered the primary regulator of thrombopoiesis and recent studies have investigated the role of thrombopoietin in inflammatory bowel disease. However, the available data are not conclusive. The aim of this study was to assess thrombopoietin serum levels in inflammatory bowel disease patients according to platelet counts, disease activity and previous thrombotic events. METHODOLOGY: Seventy-one patients with inflammatory bowel disease [41 with ulcerative colitis and 30 with Crohn's disease] and 30 healthy controls were investigated. Eight (11%) inflammatory bowel disease patients had suffered previous thromboembolic complications, none had active thrombosis. Thrombopoietin serum levels were measured by ELISA. RESULTS: Mean thrombopoietin levels were significantly increased in inflammatory bowel disease patients with active disease compared to both healthy controls and patients with inactive disease. Platelet counts were significantly higher only in patients with active disease with respect to healthy subjects. No correlation was found between thrombopoietin levels and platelet counts in either controls or inflammatory bowel disease patients. No differences were found either in thrombopoietin levels or in platelet counts comparing inflammatory bowel disease patients with and without thromboembolic complications. CONCLUSIONS: Our data show elevated thrombopoietin levels in active inflammatory bowel disease. However, no correlation was found between platelet counts and thrombopoietin levels, supporting the hypothesis that other circulating factors than thrombopoietin interact in determining reactive thrombocytosis. Furthermore, thrombopoietin levels did not differ in inflammatory bowel disease patients with or without previous thromboembolic events. This finding could be probably explained by the lack of patients with active thrombosis at the moment of inclusion in the study.

Levofloxacin based regimens for the eradication of Helicobacter pylori.

BACKGROUND: A 7 day treatment scheme based on rabeprazole/levofloxacin/amoxycillin or tinidazole achieved an eradication rate over 90%. However, the combination of drugs and duration of treatment for the correct use of levofloxacin in the eradication of are still unclear. OBJECTIVE: To compare the efficacy and tolerability of rabeprazole/levofloxacin based dual therapies given for 5, 7 or 10 days with rabeprazole/levofloxacin/amoxycillin triple therapy for 7 days. METHODS: One hundred and sixty patients with infection documented by the C-urea breath test and histology were included in this prospective, open label study. Subjects were randomized in four groups: (1) levofloxacin (500 mg o.d.), amoxycillin (1 g b.d.) and rabeprazole (20 mg o.d.) for 7 days; (2) levofloxacin (500 mg o.d.) and rabeprazole (20 mg o.d.) for 5 days; (3) levofloxacin (500 mg o.d.) and rabeprazole (20 mg o.d.) for 7 days; and (4) levofloxacin (500 mg o.d.) and rabeprazole (20 mg o.d.) for 10 days. Six weeks after the end of therapy status was checked by using the C-urea breath test. RESULTS: All patients completed the therapeutic regimens. The eradication rate was not significantly modified by treatment duration in the dual therapy schemes (5 days: 20/40, 50%; 7 days: 28/40, 70%; 10 days: 26/40, 65%). The eradication rate of the 1 week levofloxacin based triple therapy was significantly higher than that observed using any dual therapies (36/40). No major adverse effects were observed. CONCLUSIONS: A rabeprazole/levofloxacin dual eradication regimen is simple and well tolerated but does not achieve an acceptable eradication rate when compared to a 1 week rabeprazole/levofloxacin/amoxycillin triple therapy. The eradication rate did not increase with a longer regimen.

Which dimensions of health-related quality of life are altered in patients attending the different gynecologic oncology health care settings?

BACKGROUND: We evaluated the feasibility of measuring health-related quality of life (HRQOL) in a gynecologic oncology clinic by using an instrument that is nonspecific for cancer patients. Our aim was to study whether the HRQOL perception of cancer patients differed from general population norms for the same age and gender and if it varied across cancer type, cancer status, age, health care setting, and reason for the encounter. METHODS: Participants in this study included 115 women between the ages of 21 and 83 years who were referred to a university hospital for ovarian, endometrial, and cervical carcinoma. They completed the SF-36 questionnaire. Mean results for the entire sample, for different disease status (primary vs. progressive/recurrent disease), and reason for encounter (surgery, preoperative, postoperative, palliative chemotherapy, and follow-up) were compared with age-specific expected mean values for each SF-36 scale, based on published Italian reference values for the healthy population. RESULTS: Patients' attitude to the questionnaire was generally good. Mean values on the SF-36 scales varied. Role (Physical and Emotional) scales showed the highest differences from the expected age-specific values in all situations. Patients with primary disease showed little or no differences for the other six scales from the expected values, whereas a significant 10-point mean decrease in every SF-36 scale was recorded for patients with progressive/recurrent disease. A biologic interaction among cervical carcinoma, age, and disease status was found in multivariate models, showing worst scores for patients with progressive/recurrent cervical carcinoma on almost all scales. CONCLUSIONS: Administration of generic HRQOL questionnaires in specialist health care delivery settings is feasible and well accepted and may help physicians and nurses to look beyond "what's wrong" in their patients.

Reference values of fetal orbital measurements by transvaginal scan in early pregnancy.

OBJECTIVE: To construct reference ranges of orbital diameters, measured in early pregnancy by transvaginal sonography. METHODS: The study group consisted of 2717 fetuses of pregnant women referred to our center and examined by transvaginal ultrasound between 11-16 week's gestation. Nomograms with confidence intervals (5th and 95th percentile) for each orbital measurement (orbital diameter, interocular and binocular distance) versus gestational age were produced. RESULTS: The orbital measurements increased in a linear fashion throughout early pregnancy with a good correlation with gestational age. CONCLUSION: Transvaginal sonography is able to visualize and measure orbital diameters with accuracy in early pregnancy; reference ranges were developed that can be used to evaluate normal orbital development and can be helpful in the detection of syndromes with orbital growth defects and other associated fetal anomalies.

Sublingual desensitization: a new approach to latex allergy problem.

UNLABELLED: The prevalence of latex allergy has rapidly increased. Clinical manifestations range from contact urticaria-angioedema and rhinoconjunctivitis to more severe bronchial asthma and anaphylactic shock. The only effective therapy is desensitization. We studied 24 patients allergic to latex: 12 of them underwent a rush (4-day) sublingual desensitization to latex, performed by putting increasing doses of latex extract under the patients' tongues for 3 min every 20 min, followed by a maintenance therapy. The other 12 patients were considered controls. The sublingual rush desensitization protocol was successfully completed in all patients with no side effects. After 3 mo, all patients underwent an allergological evaluation, which showed a significant improvement of symptoms scores after challenges in the treated group as compared with the controls. All the desensitized patients can now wear latex gloves and undergo medical procedures without any symptoms. IMPLICATIONS: We present 12 cases of latex allergy in patients who underwent desensitization by a sublingual exposure protocol. This study provides evidence that a safe therapeutic approach to latex allergy is possible.
