Illness perception, mood and coping strategies in allergic rhinitis: are there differences among ARIA classes of severity?

BACKGROUND

This study was designed to assess if illness perception, mood state and coping strategies differ according to allergic rhinitis (AR) persistence and severity.

METHODS

Illness perception, mood profiles, coping behaviors and rhinitis symptoms were assessed by means of validated tools inpatients classified according to the Allergic Rhinitis and Its Impact on Asthma (ARIA) guidelines.

RESULTS

Two hundred and thirty-one patients underwent data analysis. No difference in age, sex, socio-economic status, smoking habits was detected comparing patients according to AR severity, duration or 4 ARIA classes. Patients with intermittent AR reported higher scores than those with persistent AR in confusion-bewilderment of Profile of Mood States (POMS); patients with moderate/severe rhinitis had significantly higher scores than those with mild rhinitis in TSSS, Identity and Consequences. No differences were detected in all assessed outcomes in the 4 ARIA classes.

CONCLUSIONS

The patient's perspective about AR is independent of persistence and severity of symptoms. This may explain why AR remains under-diagnosed and under-treated, even in its most severe forms. Self-management plans should consider the patient's perspective.

Wellbeing, Illness Perception and Coping Strategies in Italian Celiac Patients

The clinical features of Celiac Disease (CD) are heterogeneous and both severity and extent of villous atrophy do not correlate with clinical presentation. This study aims to evaluate the psychological wellbeing of CD patients with a similar clinical pattern and to explore whether patients with different levels of wellbeing differed in illness perception and coping strategies. CD outpatients with proven diagnosis filled in validated questionnaires to investigate wellbeing (PGWBI), illness perception (IPQ-R) and coping style (COPE). One hundred and four patients underwent data analysis. Compared to Italian reference sample, CD patients reported a significantly reduced PGWBI total score (p<0.001), self-control (p<0.001), general health (p=0.002) and vitality (p<0.001) and increased anxiety (p=0.009). 7.7% of patients reported a positive wellbeing, 40.4% distress absence, 28.8% a moderate distress and 23.1% a severe distress. Patients with distress showed a different illness perception and reported more frequently two dysfunctional strategies: “focus on and venting emotions” (p= 0.009) and “substance abuse” (p= 0.01) compared to those having a positive wellbeing. A high percentage of CD patients experience distress and differ from those who reach wellbeing in illness perception and use of coping strategies. Assessing subjective viewpoint with standardized methods can provide useful information for a better management of CD patients.

Chemotherapy with cisplatin and paclitaxel in locally advanced cervical cancer: has this regimen still a role as neoadjuvant setting?

AIM

Neoadjuvant chemotherapy represents a promising alternative to concomitant chemo-radiation therapy in locally advanced cervical cancer patients. The aim of this study was the evaluation of pathologic response rates, toxicity and predictors of response in locally advanced cervical cancer patients treated with neoadjuvant cisplatin and paclitaxel followed by radical surgery.

METHODS

Fourteen patients with stage IB2 to IIB cervical cancer received three cycles of cisplatin 75 mg/m2 and paclitaxel 175 mg/m2 intravenously every three weeks followed by radical hysterectomy and bilateral pelvic lymphadenectomy. Toxicity, pathologic response and predictors of response were evaluated.

RESULTS

Chemotherapy related toxicities we-re as follows: alopecia 100%, asthenia 35.7%; nausea and vomiting 14.3%; paclitaxel hypersensitivity 7.1%, neutropenia 7.1%. Optimal, partial and no pathologic response was achieved in 21.4%, 64.3% and 14.2% of the patients, respectively. Based on lack of pathologic risk factors, 43% of the patients did not receive any adjuvant radiotherapy. Better response rates were obtained in patients with stage IIB, tumor diameter <5 cm, Hb >12 g/dL and SCC antigen <1.5 mg/dL. None of these variables reached statistical significance.

CONCLUSION

Neoadjuvant chemotherapy with cisplatin and paclitaxel in locally advanced cervical cancer appeared to be well-tolerated. Even though the TIP regimen has been shown to be more effective than the TP regimen in randomized controlled prospective trial, the TP regimen remains a reasonable alternative in those patients in whom the TIP regimen is considered or shown to be too toxic.

High prevalence of vitamin D deficiency and its association with left ventricular dilation: an echocardiography study in elderly patients with chronic heart failure

BACKGROUND AND AIMS

Vitamin D deficiency has been associated with chronic heart failure (CHF). We evaluated vitamin D levels in relationship with New York Heart Association (NYHA) classes, N-terminal pro-brain natriuretic peptide (NT-proBNP) values and left ventricular (LV) measures in ≥60 year old patients with stable CHF. Differently from previous investigations, LV function was assessed by transthoracic echocardiography, to provide easily reproducible results.

METHODS AND RESULTS

The study was performed at geographic latitude 44° N, from March to May and from September to November 2008. Acute HF and diseases or drugs altering vitamin D status were exclusion criteria. NYHA scores and 25-hydroxyvitamin D [25(OH)D], 1,25-dihydroxyvitamin D and NT-proBNP concentrations were assessed in 90 (45 F, 45 M) Caucasian patients with CHF secondary to hypertension and/or coronary artery disease. Vitamin D levels were also measured in 31 subjects without heart disease (controls). LV echocardiography was performed in 52 (26 F, 26 M) representative patients. Vitamin D concentrations were significantly lower in CHF cases than in controls. Among subject with CHF, 97.8% presented vitamin D deficiency (25(OH)D<75 nmol/L), being severe (<25 nmol/L) in 66.7%. LV end-diastolic and end-systolic diameters were significantly longer, LV end-diastolic and end-systolic volumes bigger and fractional shortening lower in CHF patients with 25(OH)D<25 nmol/L than with 25(OH)D≥25 nmol/L (p<0.05). Log-values of 25(OH)D were negatively correlated with LV end-systolic diameter and volume (r=-0.28; p<0.05). On subgroup analysis, these results persisted only in male patients.

CONCLUSIONS

In elderly CHF patients, vitamin D deficiency was highly prevalent and often severe. This first addressed echocardiography study showed a sex-specific association between vitamin D deficiency and LV dilation. Since further echocardiography data are easily obtainable, larger investigations are demanded.

The risk of premalignant and malignant pathology in endometrial polyps: should every polyp be resected?

AIM

There is no wide consensus in the literature on the clinical significance and management of symptomatic and asymptomatic polyps. Aims of the study are to evaluate frequency of premalignant and malignant histo-pathologic features in endometrial polyps resected hysteroscopically and identify clinical parameters able to predict final histopathologic diagnosis.

METHODS

Clinical data and pathologic report of 90 consecutive operative hysteroscopies performed on women with endometrial polyps were collected. Frequency of premalignant and malignant histopathologic features on the polyps were calculated and relation to clinical risk factors analyzed.

RESULTS

The frequency of premalignant and malignant histopathologic features in polyps was 6.7% and 2.2% respectively. Owing to the small sample size no statistical analysis to detect clinical risk factor for premalignant or malignant histopathologic features could be performed.

CONCLUSION

Frequency of premalignant and malignant histopathologic features in symptomatic and asymptomatic patients is not negligible. Reported clinical risk factors for malignant degeneration of endometrial polypoid lesions are the same as those reported for endometrial cancer and are very common in patients with endometrial polyps. Every endometrial polyp should be resected.

Outpatient treatment of hemorrhoids with a combined technique: results in 7850 cases

A combination of sclerotherapy, rubber band ligation and infrared coagulation was performed in 7850 patients seen an outpatient clinic over a period of 9 years. The most common symptom was bleeding followed by prolapse, pain and itching. Results were considered satisfactory in 7100 patients (90.5%); 750 (9.5%) required a formal hemorrhoidectomy. Complications were mild to moderate pain in 1777 cases (22.6%), severe pain in 157 cases (2.2%), mild hemorrhage in 199 (2.5%) and hemorrhage requiring transfusion in 10 cases (0.1%). In conclusion, non-surgical outpatient treatment has a great impact on patient's perception of the disease and results in considerable savings for the healthcare system.

Chains of damages and failures in a metropolitan environment: some observations on the Kobe earthquake in 1995

The interaction and the couple effects that may occur as induced and indirect consequences of any triggering hazard in metropolitan areas is one of the most important problems to be tackled during disasters, as the Kobe earthquake in 1995 showed very clearly. The analysis of direct, secondary and indirect effects of the Kobe earthquake suggests to substitute the concept of chain of losses and failures to the simple couple hazardous event-damages which is currently used. Not only parameters related to physical weakness or strength of the built environment should be considered by scientists, experts and decision-makers. Organisational, social, and systemic factors are equally crucial to understand the magnified dimension of disasters at increasing levels of exposed systems vulnerability. Linking failures due to different kinds of vulnerability one to the other permits to reconstruct complete event scenarios, where social and organisational elements are not simply added to the 'hard' components of cities, but contribute to explain why failures and losses occurred and why it took so long to repair them. Lifeline damage assessment provides a good example to show how physical, organisational and systemic vulnerabilities are intimately connected one to the other. The point of view from which governance problems related to prevention and emergency preparedness will be looked at is that of an urban and regional planner. When planners look for design solutions suitable for a specific town or region, they must constantly bridge between hard technical matters and social and economical concerns. Furthermore, they are forced to consider in their projects spatial and geographic dimensions. Those two typical features of planners' approach to problem solving can be interesting for scholars in the field of risk assessment and mitigation research.

Quality of vision with presbyopic contact lens correction: subjective and light sensitivity rating

PURPOSE

To quantify the quality of vision achieved with multifocal and bifocal contact lenses.

METHODS

We analyzed differential light sensitivity by computerized automatic perimetry in 21 patients wearing monofocal soft contact lenses (group 1, controls) and multifocal and bifocal contact lenses (groups 2 and 3, respectively). Seven patients each were fitted with multifocal or bifocal contact lenses; seven patients were without contact lenses (without correction for testing the visual periphery and with near-vision correction using monofocal contact lens for testing the central 30 degrees of vision). The type of correction was randomly changed in a crossover fashion so that each eye was examined at different times with different corrections. Humphrey 640 VFA computerized automated perimetry was used to test visual fields at baseline, 45 days, and 3, 4.5, and 6 months.

RESULTS

A statistically significant difference was found between the global sensitivities (GS) of the central visual field in patients with near-vision monofocal contact lenses and with bifocal contact lenses (P=0.0273) and between the GS of the central visual fields with multifocal contact lenses and with bifocal contact lenses (P=0.0261). In both cases, the GS were significantly reduced with bifocal contact lenses (total GS: group 1, 11256 dB (Decibels); group 2, 11154 dB; group 3, 10679 dB).

CONCLUSIONS

The results indicate that there is reduced differential light sensitivity in the central 30 deg of the visual field with bifocal contact lenses compared with multifocal contact lenses and monofocal contact lenses (controls).

Acute effects of simultaneous intraperitoneal infusion of glucose and amino acids

BACKGROUND

The feasibility of simultaneously infusing glucose and amino acid (AA)-based peritoneal dialysis solutions was tested to determine whether peritoneal dialysis patients could achieve an adequate nonprotein calorie/nitrogen ratio while preventing a marked increase in blood urea nitrogen (BUN), which is usually seen if the AAs are administered without glucose.

METHODS

An automatic peritoneal dialysis cycler was used to infuse glucose and AA solutions (3:1) simultaneously during the night. Eight infusions of 1000 mL m2 of body surface area (BSA), with a 60 minute dwell time, were performed in 10 children on peritoneal dialysis. The dialytic effluent was analyzed at every exchange and totaled at eight hours to evaluate volume, glucose, and AA concentration. Blood samples for plasma, glucose, insulin, and free AA determination were drawn at the beginning of automated peritoneal dialysis (APD) session and at each instillation of peritoneal dialysate.

RESULTS

The mean glucose absorption was 33.7 +/- 10.0% and the AA absorption was 55.2 +/- 13.2% of the infused amount, and the ratio of nonprotein calorie (derived from glucose) to nitrogen (derived from AA) was 115.4:1. The insulin levels returned to normal only three hours after the beginning of APD. The free AA plasma levels were already increased two hours after dinner and remained high for the entire APD treatment because of the continuous absorption of AA from the peritoneum. The BUN levels did not increase despite the supply of AA.

CONCLUSIONS

This APD procedure may improve utilization of AA for protein synthesis, as suggested by the lack of increase of the BUN levels with this regimen.

Characterization of a DNA binding site that mediates the stimulatory effect of cyclosporin-A on type III collagen expression in renal cells

BACKGROUND

Previous work from our laboratory demonstrated upregulation of type III collagen by cyclosporin A (CsA) in a cellular model of renal fibroblasts 'in vitro', suggesting that a mechanism of gene transcriptional activation might be responsible for collagen accumulation in renal fibrosis resulting from chronic CsA treatment.

METHODS

We analysed in the same cellular model: (i) COL3A1 mRNA expression by RT-PCR; (ii) COL3A1 promoter activity by transfection of renal fibroblasts with constructs containing promoter fragments of different length fused to a reporter gene; (iii) expression of transcription factors by western blot analysis; (iv) DNA-protein binding by gel retardation assays with nuclear extracts from CsA-treated and untreated cells; and (v) site-directed mutagenesis of COL3A1 promoter to verify the role of a short DNA segment as CsA responsive element.

RESULTS

CsA induced a 3-5-fold increase in COL3A1 mRNA that was paralleled by a stimulation of the COL3A1 promoter. Degradation of COL3A1 mRNA was comparable in CsA-treated and -untreated cells. The target region was first limited to a 178 bp fragment from -117 to +61 (pFV1). By gel retardation, utilizing several oligonucleotides that covered the whole length of pFV1, we detected a factor able to bind the promoter DNA (oligo 31) in nuclear extracts after 3 h treatment with CsA. The binding was absent in untreated cells and it was not detected when a 10-base mutation was introduced in oligonucleotide 31. Finally, the same substitution mutation at the site of binding of this factor abolished the stimulatory effect of CsA on COL3A1 promoter. Some transcription factors, whose potential binding sites are included in the above promoter fragment, were induced by CsA treatment either soon (3 h) or late (24-72 h) after treatment and were detected by western blot analysis.

CONCLUSIONS

CsA induces the synthesis of type III collagen by stimulating a pathway leading to activation of COL3A1 promoter and upregulation of COL3A1 mRNA. A short promoter fragment, proximal to the transcription start site, is the target of CsA stimulation.

Protein and calorie intake, nitrogen losses, and nitrogen balance in children undergoing chronic peritoneal dialysis

We performed 22 nitrogen balance (NB) studies of three days' duration in 19 children (8.7 +/- 3.8 years) on chronic peritoneal dialysis (CPD) for 19.4 +/- 16.4 months. The dietary intakes were assessed by the double weighing method. Total nitrogen, protein, urea, and creatinine were analyzed in the dialysate and urine collected daily. Total nitrogen was also determined in the feces collected over the whole NB study period, using vegetable charcoal as a marker. The protein intake was 1.64 +/- 0.50 g/kg/day, corresponding to 126 +/- 40% of the recommended daily allowance (RDA) for normal children of the same age, and the calorie intake (diet+glucose from dialysate) reached 75 +/- 26% of RDA. Nitrogen losses were: 0.177 +/- 0.052 g/kg/day with peritoneal fluid and urine, and 0.028 +/- 0.018 g/kg/day with feces. The NB, positive in 17 out of 22 studies, ranged from -116 to +167 mg/kg/day (mean 44.0 +/- 66.2 mg/kg/day). A direct and significant correlation between NB and nitrogen intake (g/kg/day) (r = 0.562, p < 0.05) and total calorie intake (cal/kg/day) (r = 0.483, p < 0.05) has been observed. These data confirm the need to ensure in children on CPD an adequate nutritional intake, and further support the efforts to improve calorie intake.
