Abstract
Abstract
BACKGROUND
Glioblastoma (GBM) is a fatal tumor whose aggressiveness, heterogeneity, therapy resistance and poor blood-brain-barrier penetration hinder the amelioration of the standard-of-care. Included in the GBM mass are the tumor initiating cells (TICs), representing the driver of GBM growth and relapse in virtue of their stem-like traits and therapy-resistance. Being constantly exposed to environmental stress, including nutrients deficiency, hypoxia and therapeutic insults, all GBM cells -and TICs in particular- have to be highly adaptive in order to survive. Thus, their ability to cope with stress could be targeted to curtail TICs maintenance and the whole GBM aggressiveness. The key of TICs adaptation relies, among the others, on their epigenetic plasticity, hence encouraging epigenetic drugs testing.
MATERIAL AND METHODS
By exploiting patient-derived GBM TICs and orthotopic xenograft models, we tested the antitumorigenic features of a novel, selective, orally bioavailable and brain-penetrant Lysine-specific histone demethylase 1 inhibitor (LSD1i). We confirmed the specificity of its effects by LSD1 genetic targeting. A combination of RNA-seq, Chromatin Immunoprecipitation(ChIP)-seq, Mass Spectrometry and reverse genetic experiments unraveled LSD1 molecular players in GBM TICs.
RESULTS
We identified LSD1 as a druggable target in human GBM: LSD1i treatment, mirrored by LSD1 genetic targeting, impairs growth, viability, stem-like traits and in vivo tumorigenicity of GBM TICs. Mechanistically, LSD1 is crucial for the expression of the activating transcription factor 4 (ATF4), which coordinates the integrated stress response (ISR) to manage stressful stimuli as nutrient deprivation and endoplasmic reticulum stress. By mimicking these stress cues in vitro, we found that LSD1i triggers a delayed but unabated ATF4 translation which provokes an over-lasting ISR, eventually culminating in GBM TICs apoptosis. Lastly, LSD1 demethylase activity is dispensable for ATF4 induction. Rather, LSD1i exerts its anti-tumorigenic potential by interfering with LSD1 scaffolding function in GBM TICs.
CONCLUSION
LSD1-directed therapy is likely a promising strategy to hinder GBM. By sensitizing GBM TICs to stress, LSD1i endangers the GBM TICs pool. The effectiveness of LSD1i administration in different patient-derived GBM TICs and xenografts, regardless of their molecular profile, places a strong rationale toward the clinical translation of this approach for GBM management.

Abstract
Pulmonary interstitial emphysema (PIE) is a severe complication of mechanical ventilation in preterm infants. Selective bronchial intubation is a rarely used treatment strategy, as it is challenging, especially left main stem bronchial intubation. We report our experience in an infant at 24 weeks gestation with bedside left main stem bronchial intubation using flexible fiberoptic bronchoscopy. We also describe in detail the procedural details involved in the selective left main stem bronchial intubation including the helpful technique of gently bending the tip of the endotracheal tube to create "memory" to better direct the tube into the left main-stem bronchus while using the flexible fiberoptic bronchoscope. A review of the literature regarding selective bronchial intubation in newborn infants is presented. This case report and literature review suggest that bedside left main stem bronchial intubation using a flexible fiberoptic bronchoscope is a viable option to successfully manage even the most unstable extreme premature infant with unilateral right lung cystic PIE. This may potentially prevent a rare but necessary invasive surgical procedure like lobectomy or even death.

Abstract
BACKGROUND AND PURPOSE Mutations in the PSEN1 gene are the most common cause of autosomal-dominant Alzheimer's disease and have been associated with the earliest disease onset. We describe an unusual presentation of the rare R377W PSEN1 mutation with a late age of onset, and we provide for the first time in vivo pathological evidence for this mutation. METHODS A 71-year-old female patient with progressive cognitive decline in the past 3 years and positive family history for dementia underwent neurological evaluation, neuropsychological testing, lumbar puncture, conventional brain imaging, amyloid-positron emission tomography (PET) and extensive genetic screening with a next-generation sequencing technique. RESULTS The diagnostic workup revealed mixed behavioural and amnestic disease features on neuropsychological tests, magnetic resonance imaging, and 18-fluorodeoxyglucose (FDG)-PET. Amyloid-PET detected amyloid deposition in the frontal areas, in the parietal lobes and the precunei. The genetic screening revealed the presence of the rare R377W mutation in the PSEN1 gene. CONCLUSIONS Extensive genetic screening is also advisable for late-onset presentations of Alzheimer's disease, especially in the presence of a positive family history or atypical clinical features.

Abstract
OBJECTIVE At present, several strategies for preventing neuromuscular pain in Type 2 Diabetes Mellitus (T2DM) have been investigated. Recently, findings on genetic variants associated with adverse events to statin-based therapy have been reported. The study aimed at measuring whether Pharmacogenomics (PGx) profile can affect neuromuscular pain in patients carrying T2DM and cardiovascular diseases. An extensive panel of 5 polymorphisms on 4 candidate genes, previously validated as significant markers related to Sulphonylureas and Glitinides (SU-G) plus Simvastatin neuromuscular toxicity, is herein analyzed and discussed. PATIENTS AND METHODS We genotyped 76 T2DM patients carrying cardiovascular dyscrasia undergone anti-diabetic and anti-cholesterolemic polypharmacy. 35 subjects out of the total received concurrent SU-G and Statin-based therapy. Candidate variants consisted of drug transporters, such as Solute Carrier Organic 1B1 (SLCO1B1) Val174Ala ATP-binding cassette subfamily B member (ABCB1), subfamily C member 8 (ABCC8), and drug biotransformers of Cytochrome P450 Family (CYP) including CYP2C9*2 CYP2C9*3 CYP2C8*3, and CYP3A4*22. Moreover, we also focused on an early outline evaluation of the genotyping costs and benefits. RESULTS 6 out of 35 patients treated with SU-G plus statins (17.1% experienced adverse neuropathy events). Pharmacogenomics analysis showed a lack of any correlation between candidate gene polymorphisms and toxicity, except for the SLCO1B1 T521C allele; 14.3% of patients had a high risk for grade >2 neuromuscular pain (Odds Ratio [OR] 2.61.95% CI 0.90-7.61, p=0.03). CONCLUSIONS The clinical polymorphism effectiveness outlined therein will be assured by diagnostic improvements suitable for driving treatment decisions. In light of our experimental results and literature data, the analysis of the SLCO1B1 T521C variant will allow clinicians to take advantage from a better treatment planned for their patients in order to minimize neuromuscular pain and maximize benefits.

Abstract
Purpose Eye involvement has long been appreciated in patients with chronic graft versus host disease (cGVHD). In particular, ocular complications are frequent and can be potentially severe in patients with steroid-refractory cGVHD, and therefore necessitate close monitoring. This prospective study was designed to describe eye manifestations of cGVHD in a large series of patients monitoring them before and after 1 year of extracorporeal photochemotherapy (ECP). ECP is a relatively new therapeutic approach based on the biological effects of psoralen 8-methoxypsoralen (8-MOP) and ultraviolet A light (UVA) on mononuclear cells collected by apheresis, and reinfused into the patient. Methods Only patients with steroid-refractory cGVHD under treatment with ECP, who developed cGVHD-related eye symptoms, were selected for the study. Ophthalmologic examination was repeated every 3 months. Only patients with complete recovery of the ocular manifestations and symptoms were considered responsive. Results In our study we observed eye alterations in 24 out of 140 patients (17%) with cGVHD. After 12 months of ECP, 10 out of 21 patients (48%) completely responded to the therapy. In all these cases the contribution of ECP was also essential in all the other organs subject to cGVHD. Conclusions Further studies are necessary to clarify the role of ECP in patients with cGVHD, especially in associated eye manifestations. Although our experience is limited, it suggests that ECP could be a safe and effective therapy for steroid-refractory eye manifestations of cGVHD.

Abstract
BACKGROUND Bipolar disorder (BD) may be characterized by the presence of psychotic symptoms and comorbid substance abuse. In this context, structural and metabolic dysfunctions have been reported in both BD with psychosis and addiction, separately. In this study, we aimed at identifying neural substrates differentiating psychotic BD, with or without substance abuse, versus substance-induced psychosis (SIP) by coupling, for the first time, magnetic resonance imaging (MRI) and positron emission tomography (PET). METHODS Twenty-seven BD type I psychotic patients with (n=10) or without (n=17) substance abuse, 16 SIP patients and 54 healthy controls were enrolled in this study. 3T MRI and 18-FDG-PET scanning were acquired. RESULTS Gray matter (GM) volume and cerebral metabolism reductions in temporal cortices were observed in all patients compared to healthy controls. Moreover, a distinct pattern of fronto-limbic alterations were found in patients with substance abuse. Specifically, BD patients with substance abuse showed volume reductions in ventrolateral prefrontal cortex, anterior cingulate, insula and thalamus, whereas SIP patients in dorsolateral prefrontal cortex and posterior cingulate. Common alterations in cerebellum, parahippocampus and posterior cingulate were found in both BD with substance abuse and SIP. Finally, a unique pattern of GM volumes reduction, with concomitant increased of striatal metabolism, were observed in SIP patients. CONCLUSIONS These findings contribute to shed light on the identification of common and distinct neural markers associated with bipolar psychosis and substance abuse. Future longitudinal studies should explore the effect of single substances of abuse in patients at the first-episode of BD and substance-induced psychosis.

Abstract
It is well-known that 75% of risk factors of chronic liver disease (CLD) are related to nutrition. These circumstances potentially progress towards liver steatosis, fibrosis and hepatocellular carcinoma (HCC). It still represents an enormous problem for the economy of public health worldwide. Furthermore, validated prevention programs could be the solution. Recent knowledge in understanding molecular determinants of energy liver metabolism and new genetic markers offers new insights into the pathogenesis of CLD and HCC. The main rationale of the present issue is to provide a summary of recent insights into the inherited variants regulating lipid metabolism (steatohepatitis) and acquired mutation for early diagnosis of HCC, specifically focusing on the significance of antioxidant agents and genotyping tests as a cost-effectiveness tool for the prevention of liver disease. Several national healthy programs worldwide promote the daily use of antioxidant nutrients either for the prevention and/or as complementary and alternative medicines (CAM). This review could be advising for the planning of a large-scale clinical trial including a combination strategy of antioxidant agents and genotyping tests in patients with high risk of CLD.

Abstract
Extracorporeal photochemotherapy (ECP) has been used successfully for the treatment of chronic Graft versus Host Disease (cGvHD). However, the mechanism by which ECP exerts its protective effects remains elusive. Some recent observations have suggested a possible role of certain subsets of T lymphocytes with immunosuppressive properties (T-regulatory cells) that coexpress CD4 and high levels of the interleukin-2 receptor chain: CD4+CD25+ T lymphocytes. We studied whether ECP affects the percentage of these cells in the peripheral blood of patients with cGvHD. The study population consisted of 14 patients with cGvHD refractory to systemic steroids. On enrolment in each cycle of ECP, patients underwent clinical examination, blood chemistry analysis and other instrumental procedures to document and assess involvement of the various organs and systems. For cytofluorimetric identification and phenotyping of CD4+CD25+ T lymphocytes, peripheral blood samples were collected in EDTA anticoagulant before ECP, after 48 hours, and after 6 and 12 months from the start of treatment. The 14 patients in this study received a total of more than 300 cycles of ECP, with only minor side effects. The clinical outcome was negative in 2 patients and positive in 12 patients. Within-subject analysis indicated that the percentage of CD4+CD25+ T lymphocytes before ECP and after 12 months of treatment was significantly increased. Our study confirms that changes in the percentage of CD4+CD25+ T cells induced by ECP could be a central aspect in the cascade of immune events leading to the immunological and clinical effects of this treatment in patients with cGvHD.

However, the classic I3(-)/I(-) redox couple limits the performance and application of this technique. Simply replacing the iodine-based redox couple by new types like cobalt(3+/2+) complexes was not successful because of the poor compatibility between the ruthenium(II) sensitizer and the cobalt redox species. To address this problem and achieve higher power conversion efficiencies (PCEs), we introduce here six new cyclometalated ruthenium(II)-based dyes developed through ligand engineering. We tested DSCs employing these ruthenium(II) complexes and achieved PCEs of up to 9.4% using cobalt(3+/2+)-based electrolytes, which is the record efficiency to date featuring a ruthenium-based dye. In view of the complicated liquid DSC system, the disagreement found between different characterizations enlightens us about the importance of the sensitizer loading on TiO2, which is a subtle but equally important factor in the electronic properties of the sensitizers.

Abstract
BACKGROUND Recent studies have challenged the dogma that the adult heart is a postmitotic organ and raise the possibility of the existence of resident cardiac stem cells (CSCs). Our study aimed to explore if these CSCs are present in the "ventricular tip" obtained during left ventricular assist device (LVAD) implantation from patients with end-stage heart failure (HF) and the relationship with LV dysfunctional area extent. METHODS Four consecutive patients with ischemic cardiomyopathy and end-stage HF submitted to LVAD implantation were studied. The explanted "ventricular tip" was used as a sample of apical myocardial tissue for the pathological examination. Patients underwent clinical and echocardiographic examination, both standard transthoracic echocardiography (TTE) and speckle tracking echocardiography (STE), before LVAD implantation. RESULTS All patients presented severe apical dysfunction, with apical akinesis/diskinesis and very low levels of apical longitudinal strain (-3.5 ± 2.9%). Despite this, the presence of CSCs was demonstrated in pathological myocardial samples of "ventricular tip" in all 4 of the patients. It was found to be a mean of 6 c-kit cells in 10 fields magnification 40×. CONCLUSIONS Cardiac stem cells can be identified in the LV apical segment of patients who have undergone LVAD implantation despite LV apical fibrosis.

Abstract
A new Ru(II) dye, Ru(L1)(L2) (NCS)2, L1 = (4-(5-hexylthiophen-2-yl)-4'(4-carboxyl-phenyl 2,2'-bipyridine) and L2 = (4-4'-dicarboxy-2,2'-bipyridine), labelled MC112, based on a dissymmetric bipyridine ligand for improved interfacial and optical properties, was synthesized and used in DSCs, yielding photovoltaic efficiencies of 7.6% under standard AM 1.5 sunlight and an excellent device stability. Increased light harvesting and IPCE maximum were observed with MC112 compared to the prototypical homoleptic N719 dye, due to the functionalized bipyridyne ligand acting as an antenna. In addition, the mixed bipyridyne ligand allowed MC112 binding to TiO2 to occur via three anchoring carboxylic groups, thus exhibiting similar interfacial properties to those of the N719 dye. DFT/TDDFT calculations were performed on the new dye, both in solution and adsorbed on a TiO2 surface model, revealing that the peculiar photovoltaic properties of the MC112 dye are related to its anchoring mode. The new design rule thus allows us to engineer both light-harvesting and interfacial properties in the same dye.

Abstract
BACKGROUND AND AIM The relationships between high Creatinine (Cr) levels or low estimated Glomerular Filtration Rate (eGFR) and common carotid Intima Media thickness (IMT) have been evaluated in a population-based cohort study in women, aged 30-69 (Progetto ATENA). METHODS AND RESULTS Serum Cr and eGFR were measured in 310 women, as a part of 5.062. In this group carotid ultrasound examination (B-Mode imaging) was performed and mean max IMT was calculated. Women were classified by Cr levels >1 mg/dL or eGFR < 56 ml/min. Women with Cr > 1 mg/dL (90th percentile of creatinine distribution) or eGFR less than 56 ml/min (5th percentile of eGFR distribution) had relatively more carotid plaques as compared to the rest of the cohort. Multivariate logistic analysis, after adjustment for age, demonstrated a significant association between Cr (>1 mg/dL) and IMT (≥1.2 mm): OR 4.12 (C.I 1.22-13.86), p = 0.022; or eGFR (<56 ml/min) and IMT (≥1.2 mm): OR 4.31 (C.I 1.27-14.66), p = 0.019. CONCLUSIONS These findings on an independent relationship between Cr and common carotid plaques in this population of middle aged women, independently of age, suggest the value of screening for early carotid disease in asymptomatic middle aged-women with mild renal insufficiency, in order to predict those at relatively higher risk for future cardiovascular events.

Abstract
BACKGROUND Extracorporeal photopheresis (ECP) has been used successfully to treat severe steroid-refractory acute and chronic graft-versus-host disease (aGVHD, cGVHD) since the late 1990s. OBJECTIVES To evaluate retrospectively the efficacy and safety of ECP in patients with aGVHD. We also assessed whether ECP may play a role in the prevention of cGVHD. PATIENTS AND METHODS Nine consecutive patients with allografts with aGVHD grade II-III, as defined by consensus criteria, and refractory to steroids, were treated with ECP. ECP was started at a median interval of 46·3 days (range 10-70) from aGVHD onset. Patients were treated initially on two consecutive days (one cycle) at 1-week intervals until improvement and then every 2 weeks. Treatment was then tapered off individually. To evaluate statistical relationships with outcome after 30, 60 and 90 days of ECP, all clinical and historical variables of the patients before treatment were analysed. RESULTS All patients survived and responded within 90 days. The average aGVHD score was 1·72 at aGVHD onset, 2·44 when ECP was started and then gradually declined to 0·44 on day 90. At the same time, the average dose of methylprednisolone declined from 2·22 mg kg(-1) to 0·27 mg kg(-1) (day 90), while the average dose of ciclosporin declined from 2·46 mg kg(-1) to 0·77 mg kg(-1) (day 90). Six of nine patients showed a complete skin response after 90 days of treatment. All patients with liver and gastrointestinal tract involvement had complete responses after 90 days, apart from one patient. All our patients developed cGVHD, seven of nine while still on maintenance regimen (6-13 months after haematopoietic stem cell transplantation, HSCT) and the other two patients after suspension of ECP (6 and 9 months after HSCT). CONCLUSIONS ECP is effective in patients with mild to moderate steroid-refractory aGVHD (grade II-III). On the other hand, ECP did not prevent the development of cGVHD in our patients.

Abstract
We report a joint experimental and computational work on new organic donor-acceptor dye sensitizers in which a carbazole (CZ) and a phenothiazine (PTZ) units are linked together by an alkyl C6H13, while two different anchoring groups are employed: the cyanoacrylic acid (CS1A, CSORG1) and the rhodanine-3-acetic acid (CS4A, CSORG4). The CZ moiety has multiple roles of (i) acting as an extra-electron donor portion, providing more electron density on the PTZ; (ii) suppressing the back-electron transfer from TiO2 to the electrolyte by forming a compact insulating dye layer; (iii) modulating dye aggregation on the semiconductor surface; and (iv) acting as an antenna, collecting photons and, through long-range energy transfer, redirecting the captured energy to the dye sensitizer. We show that the introduction of the CZ donor remarkably enhances the photovoltaic performances of the rhodanine-based dye, compared to the corresponding simple PTZ dye, with more than a two-fold increase in the overall efficiencies, while it does not bring beneficial effects in the case of the cyanoacrylic-based sensitizer. Based on quantum mechanical calculations and experimental measurements, we show that, in addition to a favored long-range energy transfer, which increases the light absorption in the blue region of the spectrum, the presence of the CZ unit in the CSORG4 dye effectively induces a beneficial aggregation pattern on the semiconductor surface, yielding a broadened and red-shifted light absorption, accounting for the two-fold increase in the generated photocurrent.

Abstract
Extradural motor cortex stimulation (EMCS) has been proposed as alternative to deep brain stimulation (DBS) in the treatment of Parkinson's disease (PD). Its mechanisms of action are still unclear. Neuroimaging evidenced motor cortical dysfunction in PD that can be reversed by therapy. We performed left hemisphere EMCS surgery in six advanced PD patients fulfilling CAPSIT criteria for DBS with the exception of age >70 years. After 6 months, we measured regional cerebral blood flow (rCBF) at rest with SPECT and Tc-99m cysteinate dimer bicisate off-medication with stimulator off and on. Clinical assessment included Unified Parkinson's Disease Rating Scale part II and III, Abnormal Involuntary Movement Scale and mean dopaminergic medication dosage. We used statistical parametric mapping for imaging data analysis. Clinically we observed no mean changes in motor scales, although blinded evaluation revealed some benefit in individual patients. We found significant rCBF decrements in the pre-central gyrus, pre-motor cortex and caudate nucleus bilaterally, left prefrontal areas and right thalamus. Perfusion increments were found in cerebellum bilaterally. EMCS determined significant modulation of neuronal activity within the cortico-basal ganglia-thalamo-cortical motor loop in our cohort of advanced PD patients. However, these effects were paralleled by mild and variable clinical efficacy.

Abstract
We describe clinical and imaging features of a patient with sporadic progressive ataxia and palatal tremor (PAPT) of unknown etiology. There was hypertrophy of bilateral inferior olivary nuclei with hyperintense T2-weighted signal and mild cerebellar atrophy at brain magnetic resonance imaging. 18F-fluoro-2-desoxy-d-glucose positron emission tomography scanning (FDG-PET) showed hypometabolism in the red nucleus, external globus pallidus and precuneus while FP-CIT-SPECT imaging revealed mild and progressive loss of striatal dopaminergic terminals. Our findings suggest that in idiopathic PAPT involvement of the dentato-rubro-olivary pathway occurs along with some dopaminergic dysfunction.

Abstract
We used 123I-Ioflupane SPECT to study striatal dopamine transporter (DAT) binding in 36 Parkinson's disease (PD) patients with history of severe occupational exposure to hydrocarbons. Data were compared with 38 PD patients without exposure history as well as healthy controls. Both PD cohorts showed significant striatal uptake decrements compared with controls. We found significantly lower values in the whole striatum of exposed compared with non-exposed patients (0.83 +/- 0.25 vs. 1.05 +/- 0.39; P = 0.004), more pronounced in the putamen (0.61 +/- 0.24 vs. 0.85 +/- 0.42; P = 0.004). We conclude that severe occupational exposure to hydrocarbons may modify disease course and ultimately accelerate nigro-striatal denervation.

Abstract
Clinical diagnosis of multiple system atrophy (MSA) relays on signs and symptoms that are often difficult to identify particularly at early stage. Indeed neuropathological studies have demonstrated that MSA is the first cause of misdiagnosis in a cohort of patients presenting with parkinsonian features. Dopamine transporter imaging (DAT) shows striatal decrements in both MSA and Parkinson's disease (PD) making it not sensitive for differential diagnosis. Studies of dopamine D2 receptors with IBZM may help revealing striatal degeneration but a large overlap exist particularly if PD patients with advanced disease are included. We have measured brain flow with technetium-99m ethyl cysteinate dimer (ECD-SPECT) in 36 MSA patients and compared it with 43 PD and 39 age-matched controls. Using Statistical Parametric Mapping (SPM99) we found areas of significant reduced perfusion in the striatum, brain stem and cerebellum in MSA compared to the other groups. We believe that ECD-SPECT imaging may offer significant advantages compared to other imaging techniques in the assessment of neuronal degeneration in MSA and may help the clinician in the diagnostic characterization of patients presenting with atypical parkinsonism.

Abstract
Extracts of black cohosh (Cimicifuga racemosa) are commonly used for the treatment of symptoms associated with menopause. Adverse events with black cohosh are rare, mild and reversible. A few number of serious adverse events, including hepatic and circulatory conditions, have been also reported, but without a clear causality relationship. We report the case of a woman with severe asthenia and very high blood levels of creatine phosphokinase and lactate dehydrogenase. The patient referred to take a dietary supplement derived from black cohosh for ameliorating menopause vasomotor symptoms. To exclude a possible involvement of this product, the patient was suggested to discontinue this therapy. After suspicion the patient showed a progressive normalization of biochemical parameters and improvement of clinical symptoms. We can hypothesise a causative role for black cohosh in the muscle damage observed in this patient. Factors suggesting an association between black cohosh and the observed myopathy included the temporal relationship between use of herbal product and asthenia and the absence of other identified causative factors. Rechallenge with the suspected agent was inadvisable for ethic reasons because of the risk of a serious relapse. This is the first time that asthenia associated with high muscle enzymes serum levels by black cohosh has been reported. In our opinion, this report is of interest because of the widespread diffusion of use of black cohosh as an alternative medicine for relief from menopausal symptoms.

Abstract
Recent studies suggest that extracorporeal photochemotherapy (ECP) may be beneficial in patients with steroid-refractory chronic graft-versus-host disease (cGvHD). However, it is not yet clear whether certain conditions, such as age, mode of onset of cGvHD etc., influence clinical response and whether certain affected organs are more sensitive to ECP than others. We analysed the main clinical and laboratory parameters related to evolution of the disease in 32 steroid-refractory cGvHD patients, to identify any useful response predictors to ECP. ECP affected the course of the disease positively in 78% (25/32) of our cases.

Abstract
Vardenafil is a potent selective and reversible inhibitor of the cGMP phosphodiesterase type 5 that has been shown to improve erectile function in men. Vardenafil is usually well tolerated; the most common adverse events are headache, flushing, rhinitis, sinusitis and dyspepsia. We report a case of a 48-year-old man with an acute episode of widespread urticaria following vardenafil consumption and in absence of other identifiable causative factors. The patient had no previous episodes of urticaria. This appears to be the first report of urticaria associated with vardenafil.

Abstract
The aim of this study was to evaluate the feasibility of sentinel node (SN) biopsy in occult breast lesions with different radiopharmaceuticals and to establish the optimal lymphoscintigraphic method to detect both occult lesions and SNs (SNOLL: sentinel node and occult lesion localisation). Two hundred and twenty-seven consecutive patients suspected to have clinically occult breast carcinoma were enrolled in the study. In addition to the radioguided occult lesion localisation (ROLL) procedure, using macroaggregates of technetium-99m labelled human serum albumin (MAA) injected directly into the lesion, lymphoscintigraphy was performed with nanocolloids (NC) injected in a peritumoral (group I) or a subdermal site (group II). In group III, a sole injection of NC was done into the lesion in order to perform both ROLL and SNOLL. Overall, axillary SNs were identified in 205 of the 227 patients (90.3%). In 12/62 (19.4%) patients of group I and 9/79 (11.4%) patients of group III, radioactive nodes were not visualised, whereas SNs were successfully localised in 85 of 86 patients of group II ( P<0.001). Pathological findings revealed breast carcinoma in 148/227 patients (65.2%) and benign lesions in 79 (34.8%). A total of 131 axillary SNs were removed in 118 patients with breast carcinoma; intraoperative examination of the SNs revealed metastatic involvement in 16 out of 96 cases of invasive carcinoma (16.7%). It is concluded that the combination of the ROLL procedure with direct injection of MAA into the lesion and lymphoscintigraphy performed with subdermal injection of radiocolloids represents the method of choice for accurate localisation of both non-palpable lesions and SNs.

Abstract
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) markedly improves motor symptoms and reduces medication needs in Parkinson's disease (PD) patients. However, its effect on brain function has remained unclear. We used SPECT and the tracer ECD to measure regional cerebral blood flow before and 6 months after DBS of the STN in 22 PD patients and 13 healthy controls. PD patients were divided into good and poor responders to DBS, if changes in "off" UPDRS motor scores after surgery were >60% or <40%, respectively. Statistical analysis was performed using the SPM99 software. At baseline, all PD patients showed significant perfusion reductions in cortical areas (premotor frontal, parietal, and occipital). After DBS, changes were normalized only in the good responders, while cortical defects in the poor responders were unchanged. No flow decrements were detected in basal ganglia and thalamus in both groups, suggesting that DBS does not have a "lesion-like" effect. We conclude that good surgery outcome is associated with normalization of cortical flow abnormalities in PD.

Abstract
Deep brain Stimulation (DBS) is an effective treatment for patients with advanced Parkinson's disease (PD) and motor complications who can no longer be improved by adjustment of medical therapy. Selection of surgery candidates and follow-up after surgery are critical for good outcome. Functional neuroimaging can help in the clinical assessment of these patients. We have used single photon emission computed tomography (SPECT) and the tracer ECD to measure regional cerebral blood flow before and 6 months after DBS of the subthalamic nucleus (STN) in 20 patients with advanced PD. We found a significant increase in the anterior cingulate/supplementary motor cortex in the 12 good responders (change in off unified UPDRS >50%). Conversely, patients with poor response (n=8; change in off UPDRS-III <50% following DBS) revealed a significant worsening of cortical hypoperfusion particularly in the prefrontal areas. No flow decrements were detected in the basal ganglia and in the thalamus in both groups during DBS stimulation suggesting that DBS does not have a "lesion like" effect. If DBS stimulates and does not inactivate STN projection neurons, flow reduction in the poor responders may be secondary to increased inhibitory basal ganglia output.
