RESUMO
Migraine is a primary headache characterized by recurrent attacks of head pain associated with nausea or vomit, photophobia, phonophobia and osmophobia. The presence of osmophobia during migraine attacks seems to be a very specific complaint. Cutaneous allodynia (CA) is very common in migraineurs, and it is the most evident clinical manifestation of central sensitization, a mechanism involved in migraine chronification. This study was aimed at identifying the possible correlation between osmophobia and CA in migraineurs. 673 migraineurs were studied (492 episodic, 181 chronic). The prevalence of both CA and osmophobia was higher in chronic than in episodic migraineurs. The association between these two symptoms was significant in chronic migraineurs at Chi square test. The highlighted relationship between CA and osmophobia may be interpreted in different ways: central sensitization induced by recurrent pain stimulation may in parallel induce a distortion of both cutaneous sensitivity (CA) and olfaction (osmophobia); alternatively, the recurrent olfactory stimulation in subjects with a hypersensitivity to olfactory stimuli may co-work with repetitive pain stimulation to induce the central sensitization process.

Migraineurs brain is hyper-excitable and hypo-metabolic. Dreaming is a mental state characterized by hallucinatory features in which imagery, emotion, motor skills and memory are created de novo. To evaluate dreams in different kinds of headache. We included 219 controls; 148 migraineurs (66 with aura-MA, 82 without aura-MO); 45 tension type headache (TTH) patients. ICHD-II diagnostic criteria were used. Ad hoc questionnaire was used to evaluate oneiric activity. The Generalized Anxiety Disorder Questionnaire, and the Patient Health Questionnaire were administered to evaluate anxiety and mood. The prevalence of dreamers was similar in different groups. Frequency of visual and auditory dreams was not different between groups. Migraineurs, particularly MA, had an increased frequency of taste dreams (present in 19.6 % of controls, 40.9 % of MA, 23.2 % of MO, 11.1 % of TTH, p < 0.01), and of olfactory dreams (present in 20 % of controls, 36 % of MA, 35 % of MO and 20 % of TTH, p < 0.01). Anxiety and mood did not influence these results. The increased frequency of taste and olfactory dreams among migraineurs seems to be specific, possibly reflecting a particular sensitivity of gustative and olfactory brain structures, as suggested by osmofobia and nausea, typical of migraine. This may suggest the role of some cerebral structures, such as amygdala and hypothalamus, which are known to be involved in migraine mechanisms as well in the biology of sleep and dreaming.

BACKGROUND AND AIM: Assessment of physical activity level and of energy expenditure is important in the clinical and nutritional care of dialysis patients, but it is not so easy to accomplish. The SenseWear™ Armband (SWA) is a novel multisensory device that is worn on the upper arm and collects a variety of physiologic data related to physical activity. Thus, duration and intensity of physical activity is recorded and expressed as METs (Metabolic Equivalent Task), and energy expenditure is estimated. The aim of our study was to assess interdialytic spontaneous physical activity in stable chronic hemodialysis (HD) patients and the relation to nutritional status and dietary nutrient intake. PATIENTS AND METHODS: In 50 stable patients on maintenance hemodialysis treatment and 33 normal subjects (control group), level of spontaneous physical activity and estimated daily energy expenditure was assessed by SWA and related to biochemistry and anthropometry data, bioelectric impedance vector analysis, and energy and nutrient intake information coming from a 3-day food recall. RESULTS: In respect to controls, HD patients showed lower mean daily METs value (1.3 ± 0.3 vs. 1.5 ± 0.2, p < 0.01), a lower time spent on activities > 3 METs (89 ± 85 vs. 143 ± 104 min/day, p < 0.05), lower number of steps per day (5,584 ± 3,734 vs. 11,735 ± 5,130, p < 0.001), resulting in a lower estimated energy expenditure (2,190 ± 629 vs. 2,462 ± 443 Kcal/day, p < 0.05). 31 out of the 50 HD patients (62%) had a mean daily value < 1.4 METs and hence were defined as sedentary. They differed from the active patients for higher age (63 ± 12 vs. 54 ± 12 y, p < 0.01), lower energy intake (26.1 ± 6.4 vs. 32.4 ± 11.3 Kcal/day, p < 0.05) and lower phase angle (5.5 ± 1.0 vs. 6.3 ± 0.9, p < 0.05). SWA-based estimation of daily energy expenditure was negatively related to age (r = -0.31, p < 0.05), whereas positive relations were observed with BMI (r = 0.51, p < 0.001), phase angle (r = 0.40, p < 0.01), serum phosphate (r = 0.49, p < 0.001) and albumin (r = 0.41, p < 0.01). The mean daily METs values were strongly related to normalized energy intake (r = 0.47, p < 0.001) and also to protein intake (r = 0.33, p < 0.05) and to phase angle (r = 0.38, p < 0.01). Multiple regression analysis showed that energy intake and dietary protein intake were independently related to the intensity of physical activity. CONCLUSION: Our findings indicate that poor physical activity is highly prevalent in stable dialysis patients even when free from physical or neurological disabilities or severe comorbid conditions. The level and intensity of physical activity is positively related to body composition and to dietary nutrient intake. This confirms the strong interrelationship between exercise and nutrition, which in turn are associated with survival, rehabilitation and quality of life in dialysis patients.

AIMS: The alkaliphilic haloarchaeon Natrialba magadii secretes a halolysin-like protease (Nep) that is active and stable in high salt and in organic solvents, which represents a potential resource for biocatalysis in low water activity conditions. In this study, the effect of the growth stage on Nep biosynthesis was examined. METHODS AND RESULTS: Nep mRNA and extracellular protease activity were measured by RT-PCR and azocaseinolytic activity determination, respectively. Increased abundance in Nep mRNA was observed in Nab. magadii cells with culture age, which correlated with accumulation of extracellular protease activity. Moreover, a 'stationary phase behavior' on synthesis of Nep was evidenced in low-density cultures incubated with stationary phase medium. CONCLUSIONS: nep gene expression is up-regulated during the transition to the stationary phase in response to 'factors' (metabolite and/or regulatory molecule) occurring in high-density cultures of Nab. magadii. Although the identity of these molecules remains to be determined, preliminary evidence suggests that they are hydrophobic and stable in high salt and high pH values (3.5 mol l(-1) NaCl, pH 10). SIGNIFICANCE AND IMPACT OF STUDY: This study contributes to gain insight into the regulation of haloarchaeal protease biosynthesis, facilitating the large-scale production of this extremozyme for basic studies or potential applications.

This is a cross-sectional, multicenter, controlled study aiming to evaluate changes of actual dietary nutrient intake in 94 stable hemodialysis patients in respect to 52 normal subjects and guideline recommendations, and to assess the prevalence of signs of malnutrition. Energy and nutrients intake assessment was obtained by a three-day period food recall. Anthropometric and biochemical parameters of nutrition, bioelectric impedance vector analysis, and subjective global assessment (SGA) have been performed to assess nutritional status. SGA-B was scored in 5% of the patients. Body mass index < 20 Kg/m(2), serum albumin <35 g/L, nPNA < 1.0 g/Kg, and phase angle <4.0 degrees were detected in 16.3%, 16%, 23%, and 8.0 % of patients, respectively. HD patients showed a lower energy and protein intake in respect to controls, but no difference occurred when normalized per ideal body weight (29.3 +/- 8.4 vs. 29.5 +/- 8.4 Kcal/Kg i.b.w./d and 1.08 +/- 0.35 vs. 1.12 +/- 0.32 Kcal/Kg i.b.w. /d, respectively). Age was the only parameter that inversely correlates with energy (r = -0.35, p < 0.001) and protein intake (r = -0.34, p < 0.001). This study shows that in stable dialysis patients, abnormalities of nutritional parameters are less prevalent than expected by analysis of dietary food intake. Age is the best predictor of energy and protein intake in the dialysis patients who ate less than normal people, but no difference emerged when energy and protein intakes were normalized for body weight. These results recall the attention for individual dietetic counseling in HD patients, and also for a critical re-evaluation of their dietary protein and energy requirements.

Epidemiological data suggest an association between kidney stones and some features of metabolic syndrome such as an overweight condition, arterial hypertension or glucose intolerance. However, mechanisms remain to be elucidated. This study aimed to evaluate insulin resistance, as assessed by homeostasis model assessment (HOMA-IR), and urine composition analysis in patients affected by calcium nephrolithiasis. A cohort of 61 (38 male, 29-57 years of age) non-diabetic calcium stone formers was studied. Data about body mass index, arterial blood pressure, serum biochemistry including parathyroid hormone and calcitriol were recorded in all the patients; fasting glucose and insulin were determined to calculate HOMA-IR value and accordingly the patients were grouped into tertiles. Urine pH and urinary excretion of calcium, citrate, phosphate, oxalate, uric acid, urea and creatinine were measured on 24h urine samples. Patients of the highest HOMA-IR tertile showed lower urine citrate levels than patients of the lowest HOMA-IR tertile (475+/-243 vs. 630+/-187 mg/24h, p<0.05), whereas no difference was detected as far as urinary oxalate, calcium, uric acid, phosphate, and urine pH and urine volume output were concerned. HOMA-IR values were positively related to uric acid serum levels (r=0.31, p<0.05) and negatively to urinary citrate excretion (r=-0.26, p<0.05). Hypocitraturic patients showed higher levels of HOMA-IR than normocitraturic ones (3.03+/-0.92 vs. 2.25+/-1.19, p<0.05). This study shows that a higher level of insulin resistance is associated with lower urinary citrate excretion, and that hypocitraturic patients show a greater insulin resistance than normocitraturic calcium stone formers. This may be related to changes in citrate, Na(+)-K(+) and H(+) renal tubule transports, which have been described in insulin resistance. In conclusion, insulin resistance may contribute to an increased risk of calcium stone formation by lowering urinary citrate excretion. This finding suggests the need for a careful metabolic assessment in patients known to form calcium stones in order to ensure stone recurrence prevention and cardiovascular protection.

INTRODUCTION: We sought to examine the results of orthotopic heart transplantation accepting hearts from donors >50 years of age with special regard to the usefulness of peripheral extracorporeal membrane oxygenation for posttransplant graft dysfunction. PATIENTS: Between January 2000 and December 2004, a total of 247 patients underwent orthotopic heart transplantation. In 143 patients (58%) the heart donor was <50 years (group I, mean age of donor hearts 36 +/- 11 years; range, 8-49 years). In 104 recipients (42%) the heart donor was >50 years (group II, mean age of donor hearts 56 +/- 15 years; range, 50-67 years). Pretransplant characteristics of the two groups showed no significant differences. RESULTS: The in-hospital mortality was slightly increased in group II (24% vs 20% in group I, NS) and the 5-year survival rate significantly increased in group I (75% vs 63% in group II). Freedom from transplant vasculopathy after 3 years was similar in both groups (86% in group I vs 87% in group II). A total of 25 patients (17%) in group I and 27 patients (26%) in group II developed graft dysfunction. Eleven patients in group I and 10 patients in group II were treated using peripheral extracorporeal membrane oxygenation, whereas 3 of the 11 patients in group I and 5 of the 10 patients in group II were discharged following a complete recovery. Two patients in group I and 4 patients in group II were survivors beyond year. CONCLUSION: In our experience it was possible to increase the cardiac donor pool by accepting allografts from donors >50 years of age in selected cases. The incidence of transplant vasculopathy was not increased, whereas in-hospital mortality was slightly higher. In our limited cohort, patients with older donor hearts was developed graft dysfunction profited from primary extracorporeal membrane oxygenation implantation, an indication that should be examined further without delay.

Breast cancer rarely occurs in young women (<35 years). Several data indicate that diagnosis is associated with a worse prognosis, due to a more aggressive presentation. Although the effect of chemotherapy for premenopausal women is substantial, recent evidence suggested that patients with age <35 years with endocrine responsive tumors had a significant higher risk of recurrence than older premenopausal patients with such biological characteristics. Whereas premenopausal patients with endocrine nonresponsive disease presented similar outcome. Information from different studies of three major researching cooperative groups on breast cancer patients treated with chemotherapy alone, showed a similar interaction between the age and endocrine receptor status. Innovative treatment strategies needed and the combination of ovarian function suppression with endocrine agents (such as tamoxifen) in adjuvant therapy for endocrine receptor positive tumors could be considered. Moreover, more investigation on chemotherapy, its timing, duration, and intensity are required in the adjuvant care for endocrine nonresponsive disease. A strong emotional involvement is required to those patients approaching to adjuvant therapy, which may complicate the phase of treatment decision making. There is an urgent need for tailored clinical trials on young women with breast cancer diagnosis, to allow significant progress on adjuvant treatment of these population.

AIM: The aim of this study was to determine the frequency, anatomical site and types of injury incurred in rhythmic gymnastics. METHODS: An 8-month prospective and controlled injury survey was planned, including 70 club-level competitive rhythmic gymnasts, aged 13-19 years. Information on injury events was recorded weekly in an injury record booklet for any event occurring over that week. Height, weight, anthropometric measurements and time spent in physical activity were recorded at baseline. Data from 72 age-matched non-athletic females served as controls. RESULTS: Forty-nine significant injuries were reported by gymnasts and 34 by controls (70% vs 47%, P<0.005, odds ratio 2.28); gymnasts sustained a rate of 1.08 injuries per 1 000 h of training. The most prevalent anatomical sites sustaining injury were the ankle and the foot (38.9%), followed by back (22.2%). Strains and sprains were frequently reported both in gymnasts and in controls. Gymnasts missed an average of 4.1 days of physical activity as compared to 18.9 days for the control females. Alternatively, modification of training sessions occurred more frequently for the gymnast group (32 vs 7 cases for controls). The total school days missed were lower for the injured gymnasts than for the injured controls (27 vs 64 days). CONCLUSION: Competitive, club-level rhythmic gymnastics show a higher prevalence of injuries than non-athletic controls, but considering the high number of hours spent in training sessions, it derives that rhythmic gymnasts is a sport discipline at relatively low risk of severe injuries. These are mainly limited to back and lower limbs, are generally not severe and do not significantly hinder the preparation for the competitions.

AIM: Rhythmic gymnasts are often believed to be a population at risk of malnutrition because of their tendency to keep a low weight and a lean appearance for better athletic performance, and because they start intensive training at a very young age. The purpose of this study was to evaluate in adolescent elite gymnasts the effects of physical activity on body composition and cardiac morphology and function. METHODS: Sixteen national level rhythmic gymnasts and 16 control adolescent female underwent anthropometric measurements, bioelectric impedance and echocardiography to assess body composition and cardiac morphology and function. RESULTS: As compared to controls, gymnasts had lower body mass index (16.9±1.1 vs. 18.7±1.0, P<0.001), fatty mass (14.2±4.5 vs. 15.8±2.9 %, P<0.05) and greater fat-free mass (84.0±4.7 vs. 80.5±5.0 %, P<0.05), left ventricular end-diastolic dimension (4.7±0.4 vs. 4.4±0.3 cm) and left ventricular mass, as absolute (132.8±21.2 vs. 112.5±22.8 g, P<0.01) and indexed (44.5±9.3 vs. 36.1±8.2 g/m2.7, P<0.01). Left ventricular mass was directly related to fat-free mass as absolute (r=0.37, P<0.05) and indexed (r=0.43, P<0.02). CONCLUSION: Body composition analysis showed a lower percentage of body fat in the gymnasts, together with a higher percentage of fat-free mass. Echocardiographic findings indicate that elite rhythmic gymnastics present left ventricular remodeling as training-induced cardiac adaptation. Intensive training, dietary attitude and evident leanness of rhythmic gymnasts are not associated with cardiac abnormalities, as it is the case of pathological leanness.

A 32-year-old white woman presented with an amelanotic choroidal tumor in the left eye. Although a malignant melanoma could not be totally ruled out, some features suggested a benign tumor. The patient was followed up without treatment during a 2-year period. Neovascular glaucoma developed and the blind eye was enucleated. Histopathologic examination revealed a benign fibrous tumor of the choroid, presumably a fibrous histiocytoma.

The congenital heart disease series of the Pathological Museum at La Sapienza University of Rome was revised in order to detect specimens featuring atrioventricular valve dysplasia (AVVD) in fetuses and infants. Selected for study were 67 specimens from a collection of 667 hearts: there were 36 cases of isolated tricuspid valve dysplasia (TVD), 11 cases of isolated mitral valve dysplasia (MVD), and 20 cases of combined atrioventricular valve dysplasia. All the valves were graded according to Becker's criteria, which were morphometrically validated. There is an increasing degree of dysplasia in terms of differentiation and detachment of the valve from the ventricular wall. The concept of AVVD is supported by a substantial morphologic and morphometric analogy between TVD and MVD, in spite of some peculiarities of each grade and of side-specific anomalies ("mitral arcade" on the left side and grade III dysplasia on the right one), probably attributable to differences in the embryonic development of the two valves. AVVD is sometimes associated with dysplasia of the semilunar valves, in the setting of a polyvalvular disease of possible genetic origin. More often it is combined with other defects that cause ventricular overload. In such cases, AVVD usually occurs within the overloaded cardiac section, as if it were a result of mechanical stress.
RESUMO
The variability among subjects of the hepatic activities of O-sulphotransferase towards dopamine, p-nitrophenol, testosterone and ethinyloestradiol and of N-sulphotransferase with 1,2,3,4-tetrahydroisoquinoline (TIQ) as substrate is described. The rates of testosterone and TIQ sulphation were higher in men than women whereas those of ethinyloestradiol, dopamine and p-nitrophenol were similar in both sexes. The sulphotransferase activities towards p-nitrophenol and dopamine were positively skewed whereas those towards ethinyloestradiol approached normality. The coefficients of variations for the sulphotransferase activities ranged between 34% and 62% indicating a considerable variability among subjects. The rates of dopamine-, TIQ- and p-nitrophenol-sulphation were measured in the mucosa of the human intestine, and the duodenum/liver ratios were 10, 0.9 and 0.1, respectively. Thus the contribution of the intestine in the sulphation of xenobiotics is substrate dependent.

BACKGROUND: Young female rhythmic gymnasts have been identified as a potential risk group for malnutrition because of their attitude of weight reduction and leanness. METHODS: This study aimed to assess the dietary practices of 20 rhythmic gymnasts of the Italian national team, on the basis of a three-day food records collected by clinical interview. Twenty-four age-matched non-athletic females served as controls. RESULTS: The reported energy intake was similar in gymnasts and controls (28.5+/-5.6 vs 28.2+/-7.8 kcal/kg b.w., per day), but less than the recommended and the estimated requirements. Energy intake from carbohydrates was higher (53+/-6 vs 49+/-6%, p<0.05) and that from lipids lower (31+/-6 vs 34+/-4%, p<0.05) in gymnasts than in controls. In the former the energy supply from breakfast was higher (24+/-2 vs 16+/-4%, p<0.001) and from snacks was lower (8+/-9 vs 17+/-10%, p<0.01). Gymnasts also distinguished from controls for lower cholesterol and saturated fatty acid intake, and for higher fibre (14+/-5 vs 9+/-2 g/1,000 kcal, p<0.001) and Vitamin A dietary content. Calcium, iron and zinc intake were less than 100% RDA in both groups. CONCLUSIONS: In some ways, dietary practices of rhythmic gymnasts meet nutritional recommendations more than those of non athletic controls, though discrepancy between reported energy intake and estimated energy requirement exists. Suboptimal calcium, iron and zinc intake were observed both in gymnasts and in controls, hence minerals supplementation could be required. The dietary attitude could be regarded as a positive aspect of rhythmic gymnastics, provided athletes, physicians and coaches correct dietary errors and avoid excessive food restrictions.

AIM: It has been reported that rhythmic gymnasts are at risk of suffering from low back injuries, because of repetitive lumbar hyperextensions. On the other hand, this sport requires features of leanness, muscular strength and flexibility that should represent protective factors for back pain. METHODS: This cross-sectional study aimed to assess the prevalence of low back pain in 67 club-level competitive rhythmic gymnasts aged 13-19 years. A standardized questionnaire was used to evaluate back-pain symptoms. Anthropometric measurements, time spent in physical activity, psychological testing results, smoking habits and age of menarche were recorded. One hundred and four age-matched general females served as control group. RESULTS: Low back pain complaints were reported by 7 rhythmic gymnasts and by 27 controls (10.4% vs 26.0%, p<0.05); the prevalent location of back pain was bilateral in gymnasts and central in controls. Gymnasts had lower body weight, body mass index, fat body mass and delayed menarche. The females with low-back pain displayed higher body weight, body mass index, fat body mass, age, a greater smoking habit and more anxious/depressive behaviour, both in the gymnast and in the control group. CONCLUSION: Competitive, club-level rhythmic gymnasts show a reduced prevalence of low back-pain. Being younger in age, having greater leanness, not smoking, displaying less anxious/depressive behaviour, and developing increased muscle strength and flexibility, all can represent preventive factors for low back pain. This study suggests that rhythmic gymnastics is not a discipline at increased risk of low back pain.

BACKGROUND: Heart retransplantation (HRT) accounts for 2.6% of heart transplantation (HT) indications. We performed a retrospective analysis of our recent HRT experience. METHODS: From January 2000 to June 2012, 820 HTs were performed; 798 (97.3%) were primary HTs and 21 (2.5%) 2nd HTs. Indications for HRT included: 57% cardiac allograft vasculopathy, 33% nonspecific graft failure, 5% primary graft failure (PGF), and 5% refractory acute rejection. The primary outcome was overall survival. Our results were compared with the most representative publications reporting HRT experiences before January 2000. RESULTS: Mean age at HRT was 39.9 ± 14.3 years, and there was a predominance of male patients (62%). Overall mortality was 52%; 30-day mortality was 19%. Eight patients (38%) developed PGF after HRT and 3 of them (38%) died within 30 days. Overall actuarial survivals at 1 month and 1, 3, and 5 years were 81.0%, 70.8%, 59.9%, and 53.3%, respectively. No significant risk factors for mortality could be identified. CONCLUSIONS: We observed improved short- and medium-term survival after HRT. This finding is probably related to changing recipient profiles, with less patients being retransplanted for PGF and more patients undergoing late retransplantation. Higher rates of PGF after HRT reflect our efforts to broaden the allograft pool by using marginal donors.

BACKGROUND: Migraineurs brain has shown some functional peculiarities that reflect not only in phonophobia, and photophobia, but also in mood and sleep. Dreaming is a universal mental state characterized by hallucinatory features in which imagery, emotion, motor skills, and memory are created de novo. We evaluated dream contents and associated emotions in migraineurs. MATERIALS AND METHODS: 412 subjects: 219 controls; and 148 migraineurs (66 with aura, MA; 82 without aura, MO), and 45 tension type headache patients (TTH). A semistructured retrospective self-reported questionnaire was used to evaluate dreams. The Generalized Anxiety Disorder Questionnaire (GAD-7), and the Patient Health Questionnaire (PHQ-9) were administered to evaluate anxiety and depression. RESULTS: Migraineurs showed increased levels of anxiety (P = 0.0002 for MA versus controls, P = 0.004 for MO versus controls). Fear and anguish during dreaming were more frequently reported by migraine patients compared to controls, independently by anxiety and depression scores. DISCUSSION: The brain of migraineurs seems to dream with some peculiar features, all with a negative connotation, as fear and anguish. It may be due to the recorded negative sensations induced by recurrent migraine pain, but it may just reflect a peculiar attitude of the mesolimbic structures of migraineurs brain, activated in both dreaming and migraine attacks.

We present a rare case of bullet embolism from the left brachiocephalic vein to the right ventricle, following a chest gunshot wound, in a 56-year-old soldier. The bullet was accidentally discovered on a systematic chest X-ray. The bullet was very close to the tricuspid subvalvular apparatus and was about to come out from the ventricle. We removed it under cardiopulmonary bypass.
