Organ Care System Lung resulted in lower apoptosis and iNOS expression in donor lungs.

Ischemia-reperfusion (IR) injury after lung transplantation is still today an important complication in up to 25% of patients. The Organ Care System (OCS) Lung, an advanced normothermic ex vivo lung perfusion system, was found to be effective in reducing primary graft dysfunction compared to standard organ care (SOC) but studies on tissue/molecular pathways that could explain these more effective clinical results are lacking. This observational longitudinal study aimed to investigate IR injury in 68 tissue specimens collected before and after reperfusion from 17 OCS and 17 SOC preserved donor lungs. Several tissue analyses including apoptosis evaluation and inducible nitric oxide synthase (iNOS) expression (by immunohistochemistry and real-time reverse transcriptase-polymerase chain reaction) were performed. Lower iNOS expression and apoptotic index were distinctive of OCS preserved tissues at pre- and post-reperfusion times, independently from potential confounding factors. Moreover, OCS recipients had lower acute cellular rejection at the first 6-month follow-up. In conclusion, IR injury, in terms of apoptosis and iNOS expression, was less frequent in OCS- than in SOC-preserved lungs, which could eventually explain a better clinical outcome. Further studies are needed to validate our data and determine the role of iNOS expression as a predictive biomarker of the complex IR injury mechanism.

The mutual association between dyspnea and depressive symptoms in older adults: a 4-year prospective study.

Objectives: dyspnea in daily living (DDL), night-time dyspnea (NTD) and depression are common symptoms in older people. However, how changes in dyspnea may influence and be influenced by modifications in depressive symptoms, so far has not been fully evaluated. We aimed to estimate the extent to which both DDL and NTD could be mutually associated to depressive symptoms in older adults with chronic conditions.Methods: this prospective study includes 2322 community-dwelling individuals aged ≥65 years enrolled in the Progetto Veneto Anziani (Pro.V.A.). At baseline and after 4.4 years, we evaluated the following parameters: DDL, assessed by the Medical Research Council dyspnea scale (MRC); self-reported NTD, assessed by personal interview; depressive symptoms, assessed using the Geriatric Depression Scale (GDS). The strength of the association between dyspnea and depression over the follow-up was evaluated through logistic regression and estimated by odds ratios and 95%Confidence Intervals (95%CI). Corrected risk ratios (RR) were then approximated from odds ratios.Results: GDS changes over the follow-up positively correlated with MRC changes (ß = 0.938). Individuals with baseline DDL or NTD and those with incident/worsening DDL showed higher risk of developing or worsening depressive symptoms compared with their counterparts (RR = 3.36 [95%CI 2.11-5.06] for incident depression in people with worsening DDL). Incident or persistent depression increased more than twice the risk of developing DDL and NTD (for incident depression RR = 2.33 [95%CI 1.85-2.83] for DDL, and RR = 2.01 [95%CI 1.27-3.11] for NTD).Conclusions: older people may benefit from a comprehensive evaluation of respiratory and psychological symptoms, which seem to be related to each other in advanced age.

Postpneumonectomy bronchopleural fistula: analysis of risk factors and the role of bronchial stump coverage.

PURPOSE: Bronchopleural fistula (BPF) is a potentially fatal complication of pneumonectomy. We analyze its occurrence rate, risk factors, and the methods used for its prevention. METHODS: We reviewed the medical records of patients who underwent pneumonectomy at our Institution between January, 1990 and March, 2016. The risk factors for postoperative BPF were analyzed by univariate analysis and multiple logistic regression. RESULTS: Over the study period, 511 patients underwent pneumonectomy for non-small cell lung cancer (NSCLC) and had the bronchus closed by manual suturing. BPF developed in 23 patients (4.5%). Multiple logistic regression identified no coverage of the bronchial stump, right-sided pneumonectomy, residual tumor in the bronchial stump, postoperative ventilatory support, and completion pneumonectomy, as independent risk factors for BPF. The cumulative rate of BPF decreased significantly over time from 18% between 1990 and 1995 to 1% between 2011 and 2016 (p < 0.001). Concurrently, the data of several patients showed a significant positive trend over time, including bronchial stump coverage (BSC). DISCUSSION: Several known risk factors for BPF were confirmed. The more frequent usage of tissue flaps for coverage of the bronchial stump may have contributed to the reduction in the rate of postoperative BPF over time.

Cerebellar lesions as potential predictors of neurobehavioural phenotype in tuberous sclerosis complex.

AIM: To improve the genetic, clinical, and neuroradiological characterization of cerebellar involvement in tuberous sclerosis complex (TSC) and determine whether cerebellar lesions could be a reliable biomarker of neurological impairment. METHOD: This retrospective cohort study, held at two tertiary paediatric university centres, was conducted on patients with a confirmed diagnosis of TSC who underwent brain magnetic resonance imaging between October 2009 and May 2016. The study population consisted of 112 patients with TSC (median age 10y; range 5mo-38y; 61 females, 51 males). RESULTS: The results from multivariable statistical analysis indicated that cerebellar involvement (34 out of 112 patients, none carrying a TSC1 mutation) was the most powerful predictor of supratentorial cortical tuber load; however, cerebellar involvement was not the best predictor of clinical phenotype when supratentorial tuber load and TSC2 mutations were taken into consideration. The association between cerebellar lesions and a more severe clinical and neuroradiological phenotype was statistically significant and may be due to its strong association with TSC2 mutations and higher cortical tuber load. INTERPRETATION: Cerebellar involvement is not the best predictor of neurobehavioural outcome, including TSC-related autism, after adjusting for TSC2 and the number of cortical tubers. Its role in the TSC clinical phenotype needs to be investigated further. WHAT THIS PAPER ADDS: Cerebellar involvement is a powerful predictor of supratentorial cortical involvement and a potential biomarker of disease severity. Cerebellar lesions significantly correlate with a more severe clinical and neuroradiological phenotype. Cerebellar involvement is not the best predictor of neurobehavioural outcome.

Parathormone, vitamin D and the risk of atrial fibrillation in older adults: A prospective study.

BACKGROUND & AIMS: Vitamin D and parathormone (PTH) have been associated with cardiovascular outcomes, but their impact on atrial fibrillation (AF) onset is still unclear. We explored the influence of serum 25-hydroxyvitamin D (25[OH]D) and PTH on AF risk in older adults. METHODS AND RESULTS: Data come from 2418 participants enrolled in the Progetto Veneto Anziani study. Serum 25(OH)D and intact PTH were measured using radioimmunoassay and two-site immunoassay, respectively. The associations between 25(OH)D, PTH and adjudicated AF cases over 4-years were explored by Cox regression. Over the follow-up, 134 incident cases of AF were assessed. The incidence rate of the sample was 13.5 (95%CI 11.4-15.9) per 1000 person-years, and was higher among those with high PTH levels (high: 16.4 [95%CI 11.3-24.0] per 1000 person-years), especially when associated to low 25(OH)D (20.3 [95%CI 12.9-32.3] per 1000 person-years). At Cox regression, only high PTH was significantly associated to an increased risk of AF (HR = 1.90, 95%CI 1.27-2.84). A marginal significant interaction (p = 0.06) was found between 25[OH]D and PTH concentrations in influencing AF risk. When exploring the risk of AF for combined categories of 25(OH)D and PTH, we found that those with high PTH and low 25(OH)D levels had an AF risk twice as high as that of people with normal values (HR = 2.09, 95%CI 1.28-3.42). CONCLUSION: The risk of AF may be increased by high PTH levels, especially when associated with 25(OH)D deficiency. The identification and treatment of high PTH or vitamin D deficiency may thus contribute to lower the risk of AF.

Protocols for early discharging of premature infants: an empirical assessment on safety and savings.

Background Preterm newborns may be discharged when clinical conditions are stable. Several criteria for early discharge have been proposed in the literature. This study carried out the first quantitative comparison of their impact in terms of hospitalization savings, safety and costs. Methods This study was based on the clinical histories of 213 premature infants born in the Neonatal Intensive Care Unit of Padova University Hospital between 2013 and 2014. Seventeen early discharge criteria were drawn from the literature and retrospectively applied to these data, and computation of hospitalization savings, safety and costs implied by each criterion was carried out. Results Among the criteria considered, average gains ranged from 1.1 to 10.3 hospital days and between 0.3 and 1.1 fewer infections per discharged infant. Criteria that led to saving more hospital days had higher cost-effectiveness in terms of crisis and infection, and they spared infants from more infections. However, episodes of apnea and bradycardia were detected after the potential early discharge date for all criteria, with a mean number of episodes numbering between 0.3 and 1.4. Conclusion The results highlight a clear trade-off between days saved and health risks for infants, with potential consequences for health care costs.

The effect of childcare activities on cognitive status and depression in older adults: gender differences in a 4.4-year longitudinal study.

OBJECTIVES: Although involvement in childcare activities seems to promote better physical and mental health in older adults, its impact on cognitive status and depression has not yet been fully elucidated. We aimed to analyze the association between engagement in childcare activities and cognitive and psychological status over a 4.4-year period in community-dwelling older adults. METHODS: Two thousand one hundred four subjects older than 65 years without severe cognitive impairment at baseline were categorized according to the frequency of their involvement in childcare activities (everyday, occasionally, never). The participants' cognitive status and depressive symptoms were evaluated at baseline and after 4.4 years. RESULTS: During the follow-up, 269 (12.8%) new cases of cognitive impairment and 229 (10.9%) new cases of depression were registered. Men engaged in childcare showed an almost 20% lower risk of cognitive impairment and cognitive decline. Women demonstrated similar results, except for those occasionally involved in childcare, who had a higher risk of cognitive decline compared with women who never engaged in it. The risk of developing depression was reduced in men involved daily (OR = 0.44, 95% CI: 0.30-0.62, p < 0.0001) and occasionally in childcare, who also demonstrated a lower risk of exacerbating depressive symptoms compared with subjects who never involved in it. The onset of depression was reduced in women occasionally engaged in childcare (OR = 0.68, 95% CI: 0.56-0.82, p < 0.0001), but not significantly in those daily involved in it. CONCLUSIONS: Involvement of older adults in childcare activities seems to lower the risk of cognitive impairment in both genders and to prevent onset or worsening of depression particularly in older men.

Changes in Frailty Status and Risk of Depression: Results From the Progetto Veneto Anziani Longitudinal Study.

OBJECTIVE: To evaluate whether prefrailty was associated with the risk of developing depression and if longitudinal changes in frailty status corresponded to changes in incident depression during follow up. METHODS: A population-based, prospective cohort study was conducted for 4.4 years in two separate geographic areas near the city of Padua in the Veneto Region of Northern Italy. In 891 nondepressed, nonfrail, community-dwelling Italian subjects aged ≥ 65 (46.6% men) belonging to the Progetto Veneto Anziani study, depression was defined according to the Geriatric Depression Scale and was confirmed by geriatricians skilled in psychogeriatric medicine. Prefrailty was defined by the presence of one or two criteria among the Fried criteria. RESULTS: The incidence rate of depression was 13.3% among subjects improving their frailty status at follow-up (N = 15), 15.0% in those who remained stable (N = 79), and 26.7% among worsening participants (N = 67) (p = 0.001). Prefrailty at baseline did not predict the onset of depression (HR: 0.82; 95% CI: 0.55-1.21; Wald χ2 = 0.73; df = 1; p = 0.43), but a deterioration during follow-up in at least one additional frailty criteria was associated with a significantly higher risk (HR: 1.95; 95% CI: 1.32-2.89; Wald χ2 = 5.78; df = 2; p = 0.01). Improvement in frailty status was not associated with the risk of incident depression (HR: 0.71; 95% CI: 0.35-1.42; Wald χ2 = 0.47; df = 2; p = 0.28). CONCLUSION: Our data did not offer evidence that prefrailty per se predisposes to the onset of depression, but worsening in frailty status is associated with an almost twofold increased risk of incident depression, irrespective from the initial level of impairment.

Surgery for T4 lung cancer invading the thoracic aorta: Do we push the limits?

BACKGROUND: Few investigators have described en bloc resection of non-small cell lung cancer (NSCLC) invading the aorta. AIM OF STUDY: Analysis of outcome and prognostic factors for en bloc resections of NSCLC invading the aorta. METHODS: Thirty-five patients (27 males, 8 females; mean age 63 ± 8.6 years) were operated between 1994 and 2015 in four European Centers. HISTOLOGY: 12 (34.3%) squamous cell carcinoma, and 6 (17.1%) undifferentiated/large cell carcinoma. The site of aortic infiltration was the descending thoracic aorta in 24 (68.6%) patients, the aortic arch in 9 (25.7%), and the aortic arch and supraortic trunks in 2 (5.7%). RESULTS: Lung resection consisted of pneumonectomy in 19 (54.3%) patients and lobectomy in 16 (45.7%). Aortic resection management was undertaken by endograft positioning (37.1%), subadventitial dissection (37.1%), cardiopulmonary/aorto-aortic bypass (17.2%), and direct clamping (8.6%). A tubular graft replacement was carried out in five cases, a synthetic patch repair in 6. Mortality was 2.9%, morbidity 37.1%. Patients undergoing pneumonectomy had a significantly higher morbidity rate compared with lobectomy (52% vs 18.7%; P = 0.003), although patients managed with aortic endografting had a lower complication rate. Median overall and disease-free survival rates were 31.3 and 22.2 months, respectively. Gender and site of aortic infiltration were independent prognostic factors. CONCLUSIONS: Resection of NSCLC combined with an infiltrated aorta is a challenging procedure that can be performed with reasonable morbidity and mortality in highly selected patients.

Pain Increases the Risk of Developing Frailty in Older Adults with Osteoarthritis.

Objective: While osteoarthritis (OA)-related pain increases the risk of physical inactivity, disability, and falls, less is known about whether pain increases the risk of frailty. We investigated if people with OA reporting pain are more likely to develop frailty than people with OA without pain. Design: Population-based prospective cohort study with a follow-up of 4.4 years. Setting: Community. Subjects: The subjects were 1,775 older men and women with osteoarthritis, enrolled in the Progetto Veneto Anziani. Methods: Pain was ascertained according to medical records, symptoms/signs, and use of analgesics. Participants were considered frail if they met three out of five criteria of Fried's Index. Results: Cross-sectional analysis at baseline demonstrated that after adjusting for potential confounders (age, gender, anthropometric and demographic data, comorbidities), people with OA and pain (n = 568) were significantly more likely to have frailty compared with those with OA without pain (n = 1,207; hand OA, OR = 1.86, 95% CI = 1.65-2.09; hip OA, OR = 1.62, 95% CI = 1.44-1.83; knee OA, OR = 1.42, 95% CI = 1.26-1.60; all p < 0.0001). Prospective analysis of 1,152 nonfrail subjects at baseline demonstrated that 19.9% developed incident frailty. A fully-adjusted logistic regression analysis demonstrated that lower limb OA-related pain was associated with an increased risk of developing frailty compared with people with OA and no pain. Conclusions: Pain related to OA might be an important factor influencing the relationship between OA and the development of frailty.

Influence of splanchnic artery stenosis on the in-hospital clinical course of elderly patients.

BACKGROUND: Chronic mesenteric ischaemia (CMI) has a long asymptomatic period, but little is known about the clinical implications of this phase of the disease, particularly in the elderly, who are most exposed to the condition. AIMS: The aim of the present observational study was to survey the in-hospital clinical course of elderly patients during the non-specific phase of the disease due to occlusion of at least one splanchnic artery. METHODS: For a median of 29 months, we followed up 85 patients aged 65 and over who, for various clinical reasons, had undergone computed tomographic and magnetic resonance angiography during 2010 at Padua Teaching Hospital, assessing economic impact and reasons for admission. RESULTS: Thirty-four of these patients had at least one occluded artery, and 68 % of them had at least one hospital admission. Elderly CMI patients were characterised by a higher number of admissions (median 2 vs 1 p = 0.05) and a higher cost (6044 vs 1733 Euros p = 0.04), but did not present typical gastrointestinal symptoms. The higher number of hospital admissions was not due to specific clinical risks (admitting wards: general medicine: 32 vs 29 %, p = 0.77; general surgery 8 vs 14 %, p = 0.73; vascular surgery: 26.5 vs 20 %, p = 0.46). CONCLUSIONS: In the asymptomatic phase of CMI, hospitalised elderly patients with at least one occluded splanchnic artery can be subject to a more challenging in-hospital clinical course.

Symptomatic and presumed symptomatic focal epilepsies in childhood: An observational, prospective multicentre study.

OBJECTIVE: To describe the clinical, neuropsychological, and psychopathologic features of a cohort of children with a new diagnosis of symptomatic or presumed symptomatic focal epilepsy at time of recruitment and through the first month. The selected population will be followed for 2-5 years after enrollment to investigate the epilepsy course and identify early predictors of drug resistance. METHODS: In this observational, multicenter, nationwide study, children (age 1 month-12.9 years) with a new diagnosis of symptomatic or presumed symptomatic focal epilepsy were consecutively enrolled in 15 Italian tertiary childhood epilepsy centers. Inclusion criteria were as follows: (1) diagnosis of symptomatic focal epilepsy due to acquired and developmental etiologies, and presumed symptomatic focal epilepsy; (2) age at diagnosis older than 1 month and <13 years; and (3) written informed consent. Children were subdivided into three groups: ≤3 years, >3 to 6 years, and >6 years. Clinical, electroencephalography (EEG), neuroimaging, and neuropsychological variables were identified for statistical analyses. RESULTS: Two hundred fifty-nine children were enrolled (116 female and 143 male). Median age: 4.4 years (range 1 month-12.9 years); 46.0% (n = 119) of children were younger than 3 years, 24% (61) from 3 to 6 years of age, and 30% (79) older than 6 years. Neurologic examination findings were normal in 71.8%. Brain magnetic resonance imaging (MRI) was abnormal in 59.9%. Children age ≤3 years experienced the highest seizure frequency in the first month after recruitment (p < 0.0001). Monotherapy in the first month was used in 67.2%. Cognitive tests at baseline revealed abnormal scores in 30%; behavioral problems were present in 21%. At multivariate analysis, higher chances to exhibit more than five seizures in the first month after epilepsy onset was confirmed for younger children and those with temporal lobe epilepsy. SIGNIFICANCE: In this prospective cohort study, an extensive characterization of epilepsy onset in children with symptomatic or presumed symptomatic focal epilepsies is reported in relation to the age group and the localization of the epileptogenic zone.

Serum dehydroepiandrosterone sulfate and incident depression in the elderly: the Pro.V.A. study.

OBJECTIVE: Dehydroepiandrosterone sulfate (DHEAS) appears to have a protective effect against depression, but contrasting findings are available. Therefore, we investigated whether high serum DHEAS levels were associated with any protective effect on incident depression and incident severe depression in a representative group of elderly men and women. METHODS: In a population-based cohort longitudinal study in the general community, 789 older participants without depression and cognitive impairment at the baseline were included, among 3,099 screened subjects. Serum DHEAS levels were determined based on blood samples; incident depression and severe depression were diagnosed by means of the Geriatric Depression Scale (GDS) and confirmed by geriatricians skilled in psychogeriatric medicine. RESULTS: No baseline differences were found in GDS across age- and gender-specific tertiles of serum DHEAS. Over 4.4 years of follow-up, 137 new cases of depression were recorded. Of them, 35 among men and 64 in women were cases of incident severe depression. Cox's regression analysis, adjusted for potential confounders, revealed that higher DHEAS levels were associated with reduced risk of incident depression irrespective of gender (HR: 0.30; 95% CI: 0.09-0.96; Wald χ(2) = 4.09; df = 1; p = 0.04; women: HR: 0.31; 95% CI: 0.14-0.69; Wald χ(2) = 8.37; df = 1; p = 0.004) and of severe incident depression only in men (HR: 0.25; 95% CI: 0.06-0.99; Wald χ(2) = 4.05; df = 1; p = 0.04). CONCLUSION: Higher serum DHEAS levels were found to be significantly protective for the onset of depression irrespective of gender, whereas only in men was this association found also for incident severe depression.

Primary Dysmenorrhea in Adolescents: Prevalence, Impact and Recent Knowledge.

BACKGROUND AND OBJECTIVES: Dysmenorrhea is commonly categorized into two types; primary and secondary. Primary dysmenorrhea (PD) is the focus of this review. PD is defined as painful menses with cramping sensation in the lower abdomen that is often accompanied by other symptoms, such as sweating, headache, nausea, vomiting, diarrhea, and tremulousness. All these symptoms occur just before or during the menses in women with normal pelvic anatomy. In adolescents the prevalence of PD varies between 16% and 93%, with severe pain perceived in 2% to 29% of the studied girls. Several studies suggest that severe menstrual pain is associated with absenteeism from school or work and limitation of other daily activities. One-third to one-half of females with PD are missing school or work at least once per cycle, and more frequently in 5% to 14% of them. The wide variation in the prevalence rates may be attributed to the use of selected groups of subjects. Many risk factors are associated with increased severity of dysmenorrhea including earlier age at menarche, long menstrual periods, heavy menstrual flow, smoking and positive family history. Young women using oral contraceptive pills (OCP) report less severe dysmenorrhea. The considerably high prevalence of dysmenorrhea among adolescents verified that this condition is a significant public health problem that requires great attention. SUMMARY OF MAIN RESULTS: Many methodological problems are encountered during quantifying and grading severity of pain related to dysmenorrhea. Quantifying and assessment tools depend on women's self-reporting with potential bias. There is a scarcity of longitudinal studies on the natural history of dysmenorrhea as well as the possible effects of many modifiable risk factors. In addition, the duration of follow-up in the available studies is relatively short. Therefore, several aspects are still open for research. Medical treatment for dysmenorrhea includes anti-inflammatory drugs (NSAIDs), OCP or surgical intervention. The efficacy of conventional treatments using NSAIDs and OCP is high. However, failure rate may reach up to 20% to 25%, besides the occurrence of drug-associated adverse effects. Only 6% of adolescents receive medical advice to treat dysmenorrhea while 70% practice self-management. Unfortunately, some girls even abuse these medications (non-therapeutic high doses) for quick pain relief. The persistence of dysmenorrhea despite the use of OCP and/or NSAIDs drugs is a strong indicator of an organic pelvic disease. This condition mandates an appropriate referral to a gynecologist with proper laparoscopic diagnosis of endometriosis and/or other pelvic diseases. CONCLUSIONS: Dysmenorrhea is an important health problem for adolescents, school and occupational as well as practitioners that adversely affects the daily activities and quality of life for adolescent women. The accurate prevalence of dysmenorrhea is difficult to establish due to the variety of diagnostic criteria and the subjective nature of the symptoms. In adolescents, moderate to severe dysmenorrhea that affects lifestyle and does not respond to medical treatment requires professional attention and proper diagnosis of possible underlying pelvic disease. Therefore, adolescent care providers should be more knowledgeable and actively involved in the care of dysmenorrhea.

Headache in children with Chiari I malformation.

BACKGROUND: Headache is the most common symptom of Chiari 1 malformation, a condition characterized by the herniation of cerebellar tonsils through the foramen magnum. However, the headache pattern of cases with Chiari 1 malformations is not well defined in the literature, especially in children. OBJECTIVE: The aim of this retrospective chart review was to evaluate the frequency and the characteristics of headache in children with Chiari 1 malformation at initial evaluation and during follow up. METHODS: Forty-five cases with tonsillar ectopia were selected among 9947 cases under 18 years of age who underwent neuroimaging between 2002 and 2010. A semistructured clinical interview (mean follow-up: 5.2 years) was conducted. Headache was classified according to the second edition of the International Classification of Headache Disorders. RESULTS: Possible associations between clinical picture, in particular headache pattern, but also other signs and symptoms attributable to Chiari 1 malformation, and the extent of tonsillar ectopia were found for 3 different groups: those with borderline (<5 mm, N = 12), mild (5-9 mm, N = 27), and severe tonsillar ectopia (≥10 mm, N = 6), respectively. Twenty-four out of 33 (73%) cases with Chiari 1 malformation complained of headache, and 9/33 (27%) of those patients (5 with mild and 4 with severe tonsillar ectopia) reported headache attributed to Chiari 1 malformation. CONCLUSIONS: In our studied pediatric population, the most common symptom for cases diagnosed with Chiari 1 malformation was headache, and headache attributed to Chiari 1 malformation was the most common headache pattern in patients with Chiari 1 malformation. The presence of headache attributed to Chiari 1 malformation along with 3 other signs or symptoms of Chiari 1 malformation were highly predictive of severe tonsillar ectopia.

MR and CEUS monitoring of patients with severe rheumatoid arthritis treated with biological agents: a preliminary study.

PURPOSE: This study was done to propose a study protocol for patients with rheumatoid arthritis (RA) treated with biological agents, by evaluating the contribution of contrast-enhanced magnetic resonance (CE-MR) imaging, a software programme that calculates the volume of synovitis on CE-MR images, and contrast-enhanced ultrasound (CEUS). MATERIALS AND METHODS: Sixteen patients with RA receiving treatment with biologics were analysed. The patients underwent clinical examination, CE-MR imaging and CEUS on the same day. Images were postprocessed with the software and evaluated independently by three physicians in terms of RAMRIS (Rheumatoid Arthritis Magnetic Resonance Imaging Score), SAMIS (Simplified Rheumatoid Arthritis Magnetic Resonance Imaging Score) and CEUS grade. The techniques were correlated statistically. RESULTS: The RAMRIS and SAMIS scores were found to correlate statistically. CE-MR imaging correlated with the clinical data (p < 0.05), whereas CEUS did not. The data provided by the software did not correlate statistically with the other techniques. The most painful joint was consistently found to be the joint with most synovitis. CONCLUSIONS: CE-MR imaging may be used prior to treatment and for long-term follow-up. CEUS might be useful in the short-term follow-up, as it seems to provide an indication of the presence or absence of disease, though not of its severity. The software is a very useful tool that can supplement, but not replace, the other techniques.

Long-term outcome of morphology and function after soft tissue injury of the forearm with vascular involvement.

BACKGROUND: We sought to assess long-term changes in bone, muscle area, and muscle strength at different levels of the forearm and hand mobility according to arterial patency and nerve damage after surgically treated trauma related to involuntary local cutting/piercing injuries. METHODS: Forty subjects were evaluated 11 years after surgery for traumatic lesions involving the major vascular axis of the distal forearm. Peripheral quantitative computed tomography was used to measure cortical bone mineral density (BMD) and muscle area at the proximal radius, trabecular BMD at the distal radius, and cortical BMD at the third finger. Hand grip strength was assessed using dynamometry. Muscle area and hand grip strength were corrected for the limb dominance effect. RESULTS: All subjects had reduced trabecular BMD at the distal radius on the affected side (Δ, -5.8%; P < 0.001) and reduced cortical BMD in the third finger (Δ, -2.8%; P < 0.05). Hand grip strength was significantly lower on the affected side. According to vascular patency, only subjects with nonpreserved blood flow had significantly reduced distal radius BMD (Δ, -6.7%; P = 0.004), and those with nerve damage had a significant reduction in BMD at the third finger (Δ, -3.5%; P = 0.05). Moreover, nerve injury was associated with the presence of clinical symptoms and hand functional impairment. CONCLUSIONS: The absence of blood flow and nerve damage after forearm trauma caused by involuntary cutting/piercing injuries causes remarkable permanent impairment in musculoskeletal structures, hand grip strength, and hand functionality.

A prospective randomized trial comparing stapler and laser techniques for interlobar fissure completion during pulmonary lobectomy.

Alveolar air leaks, often resulting from lung tissue traumatization during dissection of fissures, still remain a challenging problem in lung surgery. Several tools and techniques have been used to reduce air leakage, but none was judged ideal. This prospective, randomized trial was designed to evaluate the feasibility, safety, and effectiveness of completion of fissures during pulmonary lobectomy by using a laser system. A standard stapler technique was used for comparison; the primary goal was to reach at least a comparable result. Forty-four patients were enrolled, 22 were treated with standard technique by using staplers (S) and 22 underwent laser (L) dissection. Randomization to one of the two groups was intraoperative after evaluating the presence of incomplete fissure (grade 3-4 following Craig's classification). A Thulium laser 2010 nm (Cyber TM, Quanta System, Italy) was used at power of 40 W. Outcome primary measures were the evaluation and duration of intra- and postoperative air leaks, the rate of complications, and the hospital stay. Air leaks (2.1 ± 4.2 vs 3.6 ± 7.2 days; p = 0.98) and chest tube duration (6.4 ± 4.2 vs 7.5 ± 6.3 days, p = 0.44) were lower in L compared with S group even if these were not statistically significant. Complications (36.4 vs 77.3 %; p = 0.006), hospital stay (6.9 ± 3.8 vs 9.9 ± 6.9 days; p = 0.03), hospitalization costs (5,650 vs 8,147 euros; p = 0.01), and procedure costs (77 % of difference; p < 0.0001) were significantly lower for L group, while operative time was longer (197 ± 34 vs 158 ± 41 min; p = 0.004). The use of laser dissection to prevent postoperative air leaks is effective and comparable with stapler technique. Aero-haemostatic laser properties (by sealing of small blood vessels and checking air leaks) allow a safe application during pulmonary lobectomy in interlobar fissure completion avoiding stapler use.

Osmophobia as an early marker of migraine: a follow-up study in juvenile patients.

BACKGROUND: Osmophobia is frequent in children with migraine (20-35%) but can also occur in up to 14% of cases with tension-type headache (TTH). So far, the prognostic role of this symptom in children with primary headaches has never been evaluated. METHODS: A longitudinal prospective study was conducted on 90 young patients with TTH (37 with osmophobia, 53 without osmophobia). We evaluated whether osmophobia could predict the diagnosis transformation from TTH to migraine after a 3-year follow-up. RESULTS AND DISCUSSION: In our cases the rate of diagnosis change was significantly greater in cases with osmophobia (62%) than in those without (23%). Osmophobia persisted at a 3-year follow-up in the majority of our cases (85%) and it was found to be one of the major predictors for the development of migraine; other predictors of evolution to migraine were phonophobia, a probable rather than certain diagnosis of TTH and olfactory triggers (p < 0.05). CONCLUSION: Our data confirm that osmophobia has an important diagnostic and prognostic role in children with primary headaches and should be systematically investigated at diagnosis and during follow-up.
