Quality Characteristics, Sensory Profiles and Ethylene Production of Stored 'Abate Fetel' Pears Sorted at Harvest by Time-Resolved Reflectance Spectroscopy.

Time-resolved reflectance spectroscopy (TRS), a nondestructive technique, can help the industry to provide high-quality fruit to encourage pear consumption. The absorption coefficient measured by TRS at 670 nm (670) represents a maturity index for pear fruit, with less mature pears high 670 and more mature low 670. The aim of this work was to study the quality characteristics, the sensory profiles and the ethylene production of 'Abate Fetel' pears sorted at harvest in different TRS maturity classes and stored in different atmospheres.

Perinatal skin disease present a frequent problem in clinical practise. Their treatment confronts different medical specialties. For the sake of modesty, it often takes a long time until patients seek medical attention.

Electronic nose to detect volatile compound profile and quality changes in 'spring Belle' peach (Prunus persica L.) during cold storage in relation to fruit optical properties measured by time-resolved reflectance spectroscopy.

The aim of this research was to study the relationships between electronic nose (E-nose) pattern, maturity class of peaches assessed at harvest by means of absorption coefficient at 670 nm (μ(a)670) measured in fruit pulp by time-resolved reflectance spectroscopy (TRS), and quality evolution during a 4 week cold storage. 'Spring Belle' peaches were measured for μ(a)670 by TRS, ranked according to decreasing μ(a)670 value, divided into three TRS maturity classes (less (LeM), medium (MeM), and more (MoM) mature), and randomized into 9 samples of 30 fruit each, so that fruits from the whole μ(a)670 range were present in each sample. At harvest and after 1, 2, 3, and 4 weeks of storage at 0 and 4 °C, fruits of each sample were evaluated for firmness, expressible juice, μ(a)670, and ethylene production.

Brief report: successful pregnancies but a higher risk of preterm births in patients with systemic sclerosis: an Italian multicenter study.

Objective: To assess fetal and maternal outcomes in women with systemic sclerosis (SSc).

Methods: Prospectively collected data on 99 women with SSc from 25 Italian centers were analyzed retrospectively. Women with SSc were observed during 109 pregnancies (from 2000 to 2011), and outcomes were compared to those in the general obstetric population (total of 3,939 deliveries).

A program of professional accreditation of hospital wards by the Italian Society of Internal Medicine (SIMI): self- versus peer-evaluation.

The Italian Society of Internal Medicine has developed a voluntary program of professional accreditation of the medical units run by its constituency. Participation in the program, which is meant to foster staff involvement in clinical governance, includes all the medical personnel and nurses. Accreditation is awarded provided the candidate unit is able to adhere to a pre-established set of quality standards, meet a number of clinical and organizational requirements and monitor specific indicators.

Central nervous system involvement in HCV-related mixed cryoglobulinemia.

An involvement of the peripheral nervous system is frequent in patients with HCV-related mixed cryoglobulinemia (HCV-MC), whereas central nervous system (CNS) impairment has been rarely reported. To investigate the possible CNS involvement in MC, we evaluated 18 patients by neurophysiological, neuroradiological and neuropsychological methods. Three patients (16.

Takayasu's arteritis: A study of 104 Italian patients.

Objective: Takayasu's arteritis (TA) is a rare vasculitis. The Italian Takayasu's Arteritis study group was established with the aim to describe a large cohort of patients.

Methods: Data were collected by means of an ad hoc form.

Von Willebrand factor cleaving protease (ADAMTS-13) in 123 patients with connective tissue diseases (systemic lupus erythematosus and systemic sclerosis).

Background And Objectives: Autoantibodies inactivating the von Willebrand factor (VWF) cleaving protease, ADAMTS-13, are among the most frequent causes of thrombotic thrombocytopenic purpura (TTP). We evaluated whether or not ADAMTS-13 deficiency and autoantibodies inactivating the protease prevalent in patients with the prototypic autoimmune diseases systemic lupus erythematosus (SLE) and systemic sclerosis (SSc).

Design And Methods: We measured, in parallel, the protease and VWF antigen (VWF:Ag) in 123 patients, 36 of whom had SLE and 87 of whom had SSc.

HLA class II antigens associated with lupus nephritis in Italian SLE patients.

Human leukocyte antigen DR2 (HLA-DR2), namely the allelic variant HLA-DR15, have been associated with lupus nephritis (LN) in Caucasians. The study investigated the relationships between HLA class II alleles and lupus nephritis in Italian patients. Two hundred forty-four patients fulfilling the American Rheumatism Association criteria for systemic lupus erythematosus (SLE) were typed for HLA-DRB1*, -DQA1*, -DQB1*, and -DPB1* alleles by polymerase chain reaction-sequence-specific oligonucleotide and polymears chain reaction-single-strand polymorphism; 71 patients had renal damage assessed by renal biopsy.

Clinical and serological associations of ribosomal P autoantibodies in systemic lupus erythematosus: prospective evaluation in a large cohort of Italian patients.

Objective: To verify the association of ribosomal anti-P antibodies (anti-P), as detected by a sensitive ELISA, with serological findings and clinical manifestations, including neuropsychiatric involvement evaluated according to the American College of Rheumatology (ACR) nomenclature, in a large cohort of patients with systemic lupus erythematosus (SLE).

Methods: Anti-P were evaluated in the serum of 149 consecutive Italian SLE patients by an ELISA using a multiple antigen peptide carrying four copies of a common P0, P1 and P2 epitope. A complete laboratory evaluation and clinical examination were performed in each patient.

Post-menopause is the main risk factor for developing isolated pulmonary hypertension in systemic sclerosis.

In scleroderma patients, isolated pulmonary hypertension (PHT) has been associated with selected HLA haplotypes, severe impairment of the diffusing capacity for carbon monoxide and the diagnosis of CREST. Most patients with CREST have a late-age onset of the disease, corresponding to the perimenopausal or postmenopausal period. We conducted a retrospective cohort study to determine the role of post-menopause and of the other known clinical and biological markers in the development of isolated pulmonary hypertension in Italian patients with systemic sclerosis.

Takayasu's arteritis: a changing disease.

Takayasu's arteritis (TA) is a chronic, giant-cell vasculitis of unknown etiology, which primarily involves the aorta, its main branches and coronary and pulmonary arteries. This review focuses on the epidemiological, diagnostic, and clinical aspects of the disease, which have been changed since the first description made by Mikito Takayasu in 1908. The article also summarizes the data collected by the Italian Registry of TA in the period 1993-1998.

Ventilation-perfusion lung scan for the detection of pulmonary involvement in Takayasu's arteritis.

The aim of study was to analyse ventilation and perfusion (V/Q) lung scan findings in a series of Italian patients with Takayasu's arteritis. Eighteen consecutive patients underwent V/Q lung planar scintigraphy and single-photon emission tomography (SPET). Before perfusion scan acquisition was started, a first-pass study with (99m)Tc-macroaggregates of albumin was performed to assess the right ventricular ejection fraction (RVEF).

Effects of long-term cyclic iloprost therapy in systemic sclerosis with Raynaud's phenomenon. A randomized, controlled study.

Objective: Iloprost is a stable prostacyclin analogue which has been shown to be effective in the short-term symptomatic treatment of Raynaud's phenomenon (RP) secondary to systemic sclerosis (SSc). The aim of this study was to evaluate the effects of long-term cyclic therapy with iloprost in comparison with nifedipine on the skin score, pulmonary function and Raynaud's severity score in patients with SSc and RP.

Methods: We conducted a 12-month prospective, randomised, parallel-group, blind-observer trial to compare the effects of intravenously infused iloprost (2 ng/kg/min on 5 consecutive days over a period of 8 hours/day and subsequently for 8 hours on one day every 6 weeks) with those of conventional vasodilating therapy with nifedipine (40 mg/day for os) in 46 patients with SSc and RP.

Severe polyneuropathy in a patient with Churg-Strauss syndrome.

We describe the clinicopathologic features of a 56-year-old woman affected with Churg-Strauss syndrome with major peripheral nerve involvement. The patient presented with a 1-month history of mainly distal upper-limb symmetrical paresthesias and hypostenia (bilateral "wrist drop"), palpable purpura and eosinophilia. Multiple pulmonary infiltrates and asthma had been present since the age of 52.

Five-year follow-up of 165 Italian patients with undifferentiated connective tissue diseases.

Objective: To study those conditions with a proven or hypothesised immunologic pathogenesis and denominated under a working definition of undifferentiated connective tissue diseases (UCTD).

Methods: A multicentre prospective study was organised involving 10 tertiary referral centers of internal medicine in Italy, with the aim of describing the natural history of UCTD and the prevalence of its different clinical and immunological manifestations.

Results: After a five-year follow-up period, data on 165 patients were available for analysis.

Non-invasive assessment of pulmonary artery involvement in Takayasu's arteritis.

Objective: To evaluate pulmonary involvement in Italian patients with Takayasu's arteritis (TA).

Methods: A prospective analysis of 15 Italian patients with TA was carried out, including evaluation by perfusion and ventilation lung scintigraphy (planar and tomographic), standard chest X-ray, spirography and color-doppler echocardiography. All the patients were free of respiratory symptoms when examined.

Central nervous system involvement in systemic lupus erythematosus patients without overt neuropsychiatric manifestations.

Objective: To verify whether features of CNS involvement can be detected in SLE patients without overt neuropsychiatric manifestations.

Methods: 114 SLE patients who had never received a diagnosis of neuropsychiatric lupus (never-NPSLE) were studied and compared to 65 SLE patients with known neuropsychiatric involvement (NPSLE). The study relied on evaluation of neurocognitive functions by means of a battery of neuropsychological tests, on psychiatric and neuropsychological assessments and on neuroimaging studies (computed tomography, magnetic resonance, single photon emission computed tomography (SPECT)).

Hepatitis C virus genotypes and clinical features in hepatitis C virus-related mixed cryoglobulinemia.

Mixed cryoglobulinemia is a systemic disease, almost always associated with hepatitis C virus infection and characterized by purpura and cutaneous vasculitis, asthenia, arthralgias, and often renal and neurological involvement. No significant differences have been described to date in mixed cryoglobulinemia patients with type 1, 2, or 3 hepatitis C virus infection with respect to symptoms, while a higher prevalence of genotype 2a has been reported in patients without clinical and biochemical signs of liver disease or with serum autoantibodies. We examined 33 hepatitis C virus-positive patients with mixed cryoglobulinemia to assess if any clinical or serological feature is related to infection with different genotypes.

Central nervous system involvement in patients with HCV-related cryoglobulinemia.

Central nervous system involvement was rarely described in patients with mixed cryoglobulinemia (MC). Most cases were reported before 1991, so these patients were not tested for hepatitis C virus (HCV) infection. However, two cases of cerebral ischemia in patients with HCV-related MC were recently reported.

Second line chemotherapy with ifosfamide as outpatient treatment for advanced bladder cancer.

We have carried out a phase II study in advanced or metastatic transitional cell carcinoma of the bladder. Eligible patients had unresectable bladder cancer, previously treated with one line of systemic chemotherapy. Treatment consisted of ifosfamide 1000 mg/sm in a 2-hour infusion for 5 consecutive days from d.

Intensified M-VEC chemotherapy with G-CSF support as outpatient treatment for advanced bladder cancer.

The M-VAC regimen (methotrexate, vinblastine, doxorubicin and cisplatin) is widely used in the treatment of advanced or metastatic bladder cancer. In the present trial, an alternate week regimen of M-VEC (with epidoxorubicin instead of doxorubicin) supported by G-CSF (filgrastim) was evaluated. Eligible patients had metastatic or surgically unresectable bladder cancer, not previously treated with systemic chemotherapy.
