Adaptation and psychometric properties of the Italian version of the Non-Motor Symptoms Questionnaire for Parkinson's disease.

Although non-motor symptoms (NMS) of Parkinson's disease (PD) are very common also in early stages of the disease, they are still under-recognized. Screening tools for non-motor symptoms, such as non-motor symptoms questionnaire (NMSQuest), help clinicians to recognize NMS and to evaluate if patients could require further assessment or specific treatments. To validate an adapted Italian version of NMSQuest and study its psychometric properties, Italian PD patients self-completed Italian NMSQuest, and then underwent a standard clinical evaluation including motor assessment (by Hoehn and Yahr staging, unified Parkinson's disease rating scale part III) and non-motor assessment (by Montreal cognitive assessment, Beck depression inventory, neuropsychiatric inventory, Epworth sleepiness scale, scale for outcomes in Parkinson's disease-Autonomic and movement disorder society-sponsored revision of the unified Parkinson's disease rating scale part I). Somatic comorbidities were quantified using the modified cumulative illness rating scale (CIRS). Seventy-one subjects were assessed (mean age years 69.8 ± 9.6 SD; 31% women; mean duration of disease 6.3 ± 4.6 years; H&Y median 2). Italian NMSQuest showed adequate satisfactory clinimetrics in terms of data quality, precision, acceptability, internal consistency and reliability. A significant correlation was found between NMSQuest and most of non-motor assessment scales, while no significant correlation appeared with motor severity as well as with age of patients, disease duration, levodopa equivalent daily dose, L-DOPA/dopamine agonists assumption and CIRS total score. The Italian version of the NMSQuest resulted as a reliable instrument for screening NMS in Italian PD patients.

Intercepting Parkinson disease non-motor subtypes: A proof-of-principle study in a clinical setting.

The construct of non-motor symptoms (NMS) subtyping in Parkinson Disease (PD) is emerging as a line of research in the light of its potential role in etiopathological interpretation of PD heterogeneity. Different approaches of NMS subtyping have been proposed: an anatomical model suggests that NMS aggregate according to the underpinning pathology; other researchers find aggregation of NMS according to the motor phenotype; the contribution of genetic background to NMS has also been assessed, primarily focusing on cognitive impairment. We have analyzed NMS burden assessed through an extensive clinical and neuropsychological battery in 137 consecutive non-demented PD patients genotyped for MAPT haplotypes (H1/H1 vs H2 carriers) in order to explore the applicability of the "anatomo-clinical", "motor" or "genetic" models for subtyping PD in a clinical setting; a subsequent independent analysis was conducted to verify a possible cluster distribution of NMS. No clear-cut NMS profiles according to the previously described models emerged: in our population, the autonomic dysfunctions and depressive symptoms represent the leading determinant of NMS clusters, which seems to better fit with the hypothesis of a "neurotransmitter-based" model. Selective preferential neurotransmitter network dysfunctions may account for heterogeneity of PD and could address translational research.

Validation of the Italian version of the Non Motor Symptoms Scale for Parkinson's disease.

OBJECTIVE: To validate the adapted Italian version of the Non-Motor Symptoms Scale (NMSS), a tool to assess non-motor symptoms (NMS) in Parkinson's disease (PD). METHODS: A cross cultural adaptation of the NMSS into Italian and a psychometric analysis of the translated version of the NMSS was carried out in patients with PD from two university centres-affiliated hospitals. The quality of data and the acceptability, reliability and construct validity of NMSS were analyzed. The following standard scales were also applied: Hoehn and Yahr staging, Unified Parkinson's Disease Rating Scale (UPDRS) part III, Montreal Cognitive Assessment, Beck Depression Inventory, Neuropsychiatric Inventory, Epworth Sleepiness Scale, Autonomic Scale for Outcomes in Parkinson's disease-Motor, Movement Disorder Society-Sponsored Revision of the Unified Parkinson's Disease Rating Scale part I and Modified Cumulative Illness Rating Scale (CIRS). Levodopa equivalent daily dose (LEDD) was calculated. RESULTS: Seventy-one patients with PD were assessed (mean age years 69.8 ± 9.6 SD; 31% women; mean length of disease 6.3 ± 4.6 years; H&Y median: 2). Mean NMSS was 39.76 (SD 31.9; skewness 0.95). The total score of NMSS was free of floor or ceiling effects and showed a satisfactory reliability (Cronbach's alpha coefficient on total score was 0.72 [range for domains: 0.64-0.73], SEM value was 3.88 [½ SD = 31.90]). Significant positive correlations were found among total NMSS and other NMS standard tests, but no significant correlation appeared with UPDRS part III, CIRS and LEDD. CONCLUSIONS: The Italian NMSS is a comprehensive and helpful measure for NMS in native Italian patients with PD.

Evaluation of short-term low-dose triple therapy for the eradication of Helicobacter pylori by factorial design in a randomized, double-blind, controlled study.

BACKGROUND: Studies demonstrating the efficacy of short-term low-dose triple therapies including omeprazole (O), clarithromycin (C) and a nitroimidazole (tinidazole, T) for Helicobacter pylori eradication have largely been open and uncontrolled, and have not assessed antibiotic sensitivity. Simpler regimens using the component drugs have not been evaluated. AIM: To evaluate the OCT regimen in a randomized, controlled trial, testing for pre- and post-treatment antibiotic resistance and comparing, in a factorial design, the OCT regimen with simpler combinations of its components. METHODS: One hundred and twenty-eight patients (68 males, 60 females, age 22-80 years, mean 53 years) with H. pylori gastritis were randomly assigned to one of the following four treatment groups: (C) clarithromycin 250 mg b.d.; (OC) omeprazole 20 mg o.d. + clarithromycin 250 mg b.d.; (CT) clarithromycin 250 mg b.d. + tinidazole 500 mg b.d.; (OCT) omeprazole 20 mg q.d.s. + clarithromycin 250 mg b.d. + tinidazole 500 mg b.d. The drugs were administered for 1 week. Medical interview, upper gastrointestinal endoscopy (with four antral and four corpus biopsies) and the 13C-urea breath test were carried out for all patients prior to and 4 weeks after treatment. Biopsy specimens were used for the urease test, histology, and culture and sensitivities. RESULTS: All but one patient completed treatment. Side-effects were rare and mild in all groups. The eradication rate was 93.8% in group OCT, 59.4% in group CT, 31.3% in group OC and 6.3% in group C. Pre-treatment metronidazole resistance was 12.8%, clarithromycin 1.1% and, to both antibiotics, 2.1%. In patients with pre-treatment metronidazole resistance, the eradication rate was 75% in group OCT and 33% in group CT. Post-treatment resistance to clarithromycin was induced in 28.5% of the failures in group C, but in none of group OC. Resistance to both antibiotics occurred in 22.2% of the failures in group CT and in none of group OCT. CONCLUSIONS: (i) The high efficacy of the OCT regimen is proved and each of the individual components of the regimen is essential to the result, possibly via a synergistic effect. (ii) Pre-treatment metronidazole resistance is scarcely relevant to the outcome. (iii) Acquired resistance is essentially nil if omeprazole is part of the regimen.

Low-dose lansoprazole and clarithromycin plus metronidazole vs. full-dose lansoprazole and clarithromycin plus amoxicillin for eradication of Helicobacter pylori infection.

AIM: To compare, in a randomized controlled trial, the efficacy and tolerability of two 1-week triple therapies for Helicobacter pylori eradication. METHODS: One hundred and thirty-four consecutive patients with non-ulcer dyspepsia and H. pylori infection were randomized to receive lansoprazole 30 mg once daily, clarithromycin 250 mg twice daily, and metronidazole 500 mg twice daily (LCM group), or lansoprazole 30 mg twice daily, clarithromycin 500 mg twice daily, and amoxicillin 1000 mg twice daily (LCA group). H. pylori status was assessed by rapid urease test, histology and 13C-urea breath test before and after therapy. RESULTS: At 3 months, H. pylori eradication (intention- to-treat/per protocol analysis) was 92.4%/93.8% in the LCM group and 83.1%/85.7% in the LCA group (P=N.S.). Side-effects were more frequently reported in the LCA group (37.9%) than in the LCM group (19.7%) (P < 0.05). CONCLUSIONS: In this open, randomized controlled trial, eradication of H. pylori by low-dose lansoprazole and clarithromycin plus metronidazole was higher with significantly less side-effects than by full-dose lansoprazole and clarithromycin plus amoxicillin. This finding may be related to the stronger synergism of clarithromycin plus metronidazole, even at lower doses, than of clarithromycin plus amoxicillin. Considering the lower cost as well, LCM should be preferred to LCA in the eradication of H. pylori.

Silent oophoritis due to cytomegalovirus in a patient with advanced HIV disease.

A case of isolated necrotizing cytomegalovirus (CMV) oophoritis disclosed only by necropsy studies in a patient with AIDS, is described. This unusual case report is discussed with a review of the literature dealing with CMV involvement of genital organs in the immunocompromised host, and in patients with HIV infection and AIDS.

Brain stem encephalitis in a patient with gastroduodenal and cardiovascular dysfunction: a case report.

The authors describe a case of a 38-year-old woman suffering from long-standing epigastric pain, abdominal fullness and vomiting due to functional alteration of gastroduodenal motility. Following a surgical procedure, a supraventricular tachyarrhythmia and hemodynamic disturbances suddenly appeared and led to death in a few hours. A histopathological study carried out on the brain stem revealed inflammatory lesions suggestive of a viral infection, whereas the study of the conduction system of the heart did not show any alterations. A clinicopathological correlation is suggested between the clinical picture and anatomical lesions of the tegmental region.

Colitis associated to chemotherapy with 5-fluorouracil.

Antitumoral agents, especially when administered in combination, can induce pseudomembranous colitis, due to their antimitotic and antibacterial properties. Although patients given 5-fluorouracil frequently show nonspecific colitis or diarrhea without colitis, very few cases of proven pseudomembranous colitis have been described during 5-fluorouracil monotherapy. We describe the second case reported in the English literature of a typical pseudomembranous colitis occurring in a patient given 5-fluorouracil as a single antimitotic agent for colonic cancer. Intestinal injury was not preceded by antibiotic therapy. Although both stool and pseudomembrane culture did not yield C. difficile, oral vancomycin was started. This treatment led to a prompt improvement of intestinal symptoms and colitis was resolved in one week.

Cancer of the appendix in long-standing ulcerative colitis: a case report.

Cancer of the appendix was found in a 69-year-old female patient affected by long-standing ulcerative colitis (UC). On histological examination the cancer was a typical cystadenocarcinoma of the appendix. The appendiceal mucosa not invaded by the neoplastic process was normal. Histological examination of the colorectal mucosa did not show dysplasia or cancer. These findings suggest that appendiceal cancer and UC may be unrelated diseases. A surveillance program for early detection of cancer of the appendix in patients with long-standing UC does not seem mandatory.

[50 cases of early gastric cancer]. / Considerazioni su 50 casi di early gastric cancer.

Among 530 surgical specimens of histologically proved cancer or ulcer of the stomach during the last 5 years, 50 were classified as early gastric cancer. The increasing number of cases described in the recent years may be attributed to the more aggressive diagnostic approaches. 26 cases were confined to the mucosa and the remaining 24 invaded the submucosa. Lymph node metastasis was present in 4 patients. Surgical approach, with antrectomy, subtotal or total gastrectomy with radical lymphectomy, is pratically necessary.

Atypical juvenile polyposis.

Two cases of atypical juvenile polyposis are described in males of 9 months and 25 years-of-age. The first was associated with congenital megacolon and presented as juvenile polyps with features suggesting mild dysplasia. In the second case six histological lesions are found: I hyperplastic polyps; 2 juvenile polyps; 3 hyperplastic polyps with adenomatous areas; 4 juvenile polyps with areas of dysplastic epithelium; 5 adenomas; and 6 adenocarcinomas. On the basis of the morphological features we propose a pathogenetic sequence of focal mucosal hyperplasia to adenoma and carcinoma through stages of non-neoplastic and non premalignant polyps. Finally, the possibility that hyperplastic epithelium can in some circumstances have a greater dysplastic potential that normal colorectal mucosa is raised.

[Prognostic anatomical features in the colon-rectum carcinoma (author's transl)]. / Facteurs anatomiques et pronostiques des cancers du côlon et du rectum.

We have reviewed 415 cases of colon-rectum carcinoma in order to establish the most important prognostic anatomical features. Furthermore, we have examined the associated adenomatous polyps, and the possible relationships between anatomical and histological aspects and Dukes stage of carcinoma. We have searched for some useful parameters to decide whether 5 centimeters between neoplasia and resection line is the correct surgical treatment.

A rare case of mucous-secreting villous adenoma of the bladder.

A case of mucous-secreting villous adenoma of the urinary bladder associated with cystitis glandularis is reported which led to radical cystectomy because of the extensive bladder involvement. An immunohistochemical study was performed in order to detect ABH tissue antigens. The histogenesis and the possible malignant potential of this neoplasm are discussed.

Distribution of basement membrane antigens in bladder carcinomas: an additional prognostic parameter. Immunohistochemical study.

A retrospective study of basement membrane (BM) components (laminin and type IV collagen) in urothelial tissues was performed by applying an immunoperoxidase method to 64 formalin-fixed specimens. The distribution of laminin and type IV collagen was investigated in normal and non-cancerous epithelium (11 cases), where the staining of the basement membrane was continuous. In the invasive bladder carcinomas (53 cases), two distinct staining patterns were observed both with type IV collagen and with laminin: preserved or thin and discontinuous (pattern I) and fragmented or absent (pattern II). These patterns were largely related to the type of growth of the bladder neoplasias ("pushing margin" or "finger-like") and to the cellular arrangement. Furthermore, five-year survival exceeded 70% in patients with pattern I, whereas only three of the 18 patients with pattern II survived for five years or more.

Cystic lesion of the kidney with ultrastructural evidence of mesothelial origin.

A case of cystic renal mesothelioma in a 55 year-old woman is described. The patient had only intense pain in the left lumbar region. The tumor macroscopically appeared as a cystic multilocular mass, 20 cm. in diameter, sharply demarcated from the renal parenchyma. A light and electron microscope study was performed, and strongly supported mesothelial origin. The patient was treated by surgical therapy which was completely resolutive. The differential diagnosis between this tumor and peri and para-renal cystic lesions is discussed.

[Segmental anatomic diagnosis in congenital cardiac anomalies. II: Sequential localization of the cardiac chambers (author's transl)]. / Diagnostica segmentaria anatomica nelle cardiopatie congenite. II. Localizzazione sequenziale delle cavità cardiache.

The approach to the diagnosis of congenital heart disease, based upon the identification of the cardiac chambers, the reconstruction of their sequence and final recognition of the basic circulatory model is discussed. Three cardiac segments are recognizable embriologically, anatomically and functionally: atria, ventricles and great arteries. Connexion is the sequential link of these segments, independently from their spatial relationship. Situs of the atria can be: solitus, inversus or ambiguus, and is determined by the thoracic situs which can be assumed from the bronchial anatomy. Atrio-ventricular connexion can be concordant, absent or double inlet ventricle. Ventricular-arterial connexion can be concordant, discordant, double outlet ventricle or single outlet heart. Since this approach aims to the reconstruction of the connexion among the cardiac segments, heart position and the infundibular anatomy are not relevant to the recognition of the circulatory model.

[Segmental anatomic diagnosis in congenital cardiac anomalies. I. Anatomic criteria for the identification of the cardiac cavities (author's transl)]. / Diagnostica segmentaria anatomica nelle cardiopatie congenite. I. Criteri anatomici per la identificazione delle cavità cardiache.

Anatomical features are illustrated for the identification of the cardiac chambers. Essential and accessory morphological structures are recognized. The identification of the atrial cavities is based upon the anatomy of the free walls (crista terminalis, size and shape of the atrial appendages). On the contrary, the identification of the ventricles is founded on the septal morphology (trabecula septo-marginalis on the morphological right side, smooth basal septum on the morphological left side, presence or absence of septal insertions of the atrio-ventricular value apparatus). Finally, no essential feature can be applied to the identification of the great arteries.

Retrospective studies of early gastric cancer in a high incidence area of Italy.

Frequency and characteristics of early gastric cancer (egc) were evaluated in a retrospective study of 511 surgical specimens of gastric carcinoma. We observed a total of 46 egc in 40 patients. The predominant macroscopic type was IIc, followed by I and III. On the basis of histological appearance, 25 egc were of intestinal type and 15 of diffuse type. Seventy-six per cent of egc were localized at the lesser curvature of the stomach and in particular at the pyloric antrum. Twenty-two egc were limited to the muscosal layer. no relationship was observed between macroscopic type or histological characters, and tumour staging. As Italy can be considered a high-risk country for gastric carcinoma and because this disease is in many respects similar to that observed in Japan, it seems possible to obtain a reduction of the death rate for gastric cancer by increasing, as in Japan, the number of cancers diagnosed in the early phase.

[Transposition of the great arteries: anatomic types of left ventricular outflow tract obstruction (author's transl)]. / Trasposizione completa delle grandi arterie. Quadri anatomici delle ostruzioni all'efflusso ventricolar sinistro.

A postmortem investigation has been carried out in 48 heart specimens with transposition of the great arteries (TGA) to evaluate incidence and type of left ventricular outflow tract obstruction. The frequence of pulmonary stenosis in our series (23%) is similar to those reported from previous studies. Cases have been divided in two groups according to presence or absence of ventricular septal defect. In cases with intact ventricular septum the obstruction was determined by asymmetric hypertrophy of the septum (1 observation) and by abnormal attachement of clefted anterior mitral leaflet to the interventricular septum (2 observations). In the specimens with ventricular septal defect, 4 presented a stenosis due to malalignment of the infundibular septum, associated with valvular stenosis in 1 case and with valvular stenosis and fibrous subvalvular ring in 2. Another case presented a stenotic pulmonary valve and a parachute mitral valve. The remaining 3 showed a cleft of the anterior leaflet of the mitral valve. The high incidence of infundibular malalignment obstruction is underlined together with its association with A-P or L-position of the aorta. This peculiar relation of the great arteries could be angiocardiographically employed as indicative for the presence of this type of left outflow tract obstruction in TGA.
