Indocyanine green fluorescence applied to gynecologic oncology: beyond sentinel lymph node.

Indocyanine green (ICG), a well-known molecule employed in medicine for over five decades, has emerged as a versatile dye widely embraced across various surgical disciplines. In gynecologic oncology, its prevalent use revolves around the detection of sentinel lymph nodes. However, the true potential of ICG extends beyond this singular application, owing to its pragmatic utility, cost-effectiveness, and safety profile. Furthermore, ICG has been introduced in the theranostic landscape, marking a significant juncture in the evolution of its clinical utility. This narrative review aims to describe the expanding horizons of ICG fluorescence in gynecologic oncology, beyond the sentinel lymph node biopsy. The manifold applications reported within this manuscript include: 1) lymphography; 2) angiography; 3) nerve visualization; 4) ICG-driven resections; and 5) theranostic. The extensive exploration across these numerous applications, some of which are still in the pre-clinical phase, serves as a hypothesis generator, aiming to stimulate the development of clinical studies capable of expanding the use of this drug in our field, enhancing the care of gynecological cancer patients.

Etiology, presentation and management of urinary tract infections in multiple sclerosis patients: A review of the current literature.

Urinary tract infections (UTIs) present a formidable challenge in the care of individuals affected by multiple sclerosis (MS). Lower urinary tract dysfunction is a prevalent issue among MS patients, predisposing them to an elevated risk of UTIs. When left untreated, UTIs can further exacerbate the already compromised quality of life in individuals with MS. The diagnosis and management of UTIs in MS patients necessitate a careful clinical evaluation. The objective of this review is to delineate preventive strategies and current and developing therapeutic approaches for preventing and treating UTIs associated with urinary dysfunction, catheterization, and upper urinary tract infections in patients with MS. Effectively addressing UTIs and urinary tract dysfunction in individuals with multiple sclerosis calls for a comprehensive, interdisciplinary approach.

Radical Nephroureterectomy Tetrafecta: A Proposal Reporting Surgical Strategy Quality at Surgery.

Background: Standardized methods for reporting surgical quality have been described for all the major urological procedures apart from radical nephroureterectomy (RNU). Objective: To propose a tetrafecta criterion for assessing the quality of RNU based on a consensus panel within the Young Association of Urology (YAU) Urothelial Group, and to test the impact of this tetrafecta in a multicenter, large contemporary cohort of patients treated with RNU for upper tract urothelial carcinoma (UTUC). Design setting and participants: This was a retrospective analysis of 1765 patients with UTUC treated between 2000 and 2021. Outcome measurements and statistical analysis: We interviewed the YAU Urothelial Group to propose and score a list of items to be included in the "RNU-fecta." A ranking was generated for the criteria with the highest sum score. These criteria were applied to a large multicenter cohort of patients. Kaplan-Meier curves were built to evaluate differences in overall survival (OS) rates between groups, and a multivariable logistic regression model was used to find the predictors of achieving the RNU tetrafecta. Results and limitations: The criteria with the highest score included three surgical items such as negative soft tissue surgical margins, bladder cuff excision, lymph node dissection according to guideline recommendations, and one oncological item defined by the absence of any recurrence in ≤12 mo. These items formed the RNU tetrafecta. Within a median follow-up of 30 mo, 52.6% of patients achieved the RNU tetrafecta. The 5-yr OS rates were significantly higher for patients achieving tetrafecta than for their counterparts (76% vs 51%). Younger age, lower body mass index, and robotic approach were found to be independent predictors of tetrafecta achievement. Conversely, a higher Eastern Cooperative Oncology Group score, higher clinical stage, and bladder cancer history were inversely associated with tetrafecta. Conclusions: Herein, we present a "tetrafecta" composite endpoint that may serve as a potential tool to assess the overall quality of the RNU procedure. Pending external validation, this tool could allow a comparison between surgical series and may be useful for assessing the learning curve of the procedure as well as for evaluating the impact of new technologies in the field. Patient summary: In this study, a tetrafecta criterion was developed for assessing the surgical quality of radical nephroureterectomy in patients with upper tract urothelial carcinoma. Patients who achieved tetrafecta had higher 5-yr overall survival rates than those who did not.

The impact of COVID-19 outbreak on urolithiasis emergency department admissions, hospitalizations and clinical management in central Italy: a multicentric analysis. / El impacto de la COVID-19 en las admisiones al servicio de urgencias, hospitalizaciones y manejo clínico de la urolitiasis en el centro de Italia: análisis multicéntrico.

INTRODUCTION AND OBJECTIVES: We aimed to evaluate how the corona virus disease of 2019 (COVID-19) outbreak influenced emergency department (ED) admissions for urolithiasis, hospitalizations and clinical management of the hospitalized patients. PATIENTS AND METHODS: We conducted a multicentric retrospective analysis of ED admissions in three high volume urology departments (one directly involved in COVID-19 patients management and two not involved) in Rome - Italy between March and April 2020 and in the same period of 2019. Statistical analysis was conducted on the number of admissions for urolithiasis, rate of complications, hospitalization and the type of treatment received. RESULTS: 304 patients were included in the analysis. A significant reduction in the global number of patients admitted to ED for urolithiasis between 2019 and 2020 (48.8%) was noted. Moreover, regarding the choice of treatment of hospitalized patients, a statistically significant increase of stone removal procedures versus urinary drainage was reported in 2020 (p = 0.015). CONCLUSIONS: During the COVID-19 pandemic in Rome there has been a significant reduction of emergency admissions for urolithiasis. Patients admitted to ED had more complications, more frequently need hospitalization and regarding clinical management early stone removal was preferred over urinary drainage only. All the urologists should be aware that in the next months they could face an increased number of admissions for urolithiasis and manage more complicated cases.

Imitation Strategies in Callosotomized Patients.

Imitation is a human ability rooted in early life. It allows people to interact with each other by observing and reproducing simple and complex movements alike. Imitation can occur in at least two forms: the rst, de ned as anatomical, seems to be based primarily on the mental construct of the "body schema" because the imitating movement corresponds precisely to the imitated movement in bodily terms, but not in terms of spatial compatibility. For example, a right arm movement of a model is imitated with a right arm movement by a facing imitator in a spatially incompatible fashion. The other form, de ned as specular or mirror-mode, involves a spatially compatible matching between imitated and imitating movements, as when an imitator moves her right arm upon viewing a corresponding left arm movement of a facing model (Chiavarino et al., 2007). In a previous study, healthy subjects showed a slight (61%) preference for the specular mode when freely imitating meaningful and meaningless gestures, whereas they strongly preferred the anatomical mode (93%) when given an intentionally ambiguous instruction such as "use the same (or the opposite) limb as the model" (Pierpaoli et al., 2014). In the present investigation it has been shown that callosotomized patients tended to favour the mirror-mode in both the free (66%) and the instructed condition (61% responses in driven sessions) regardless instructions given by the experimenter. Moreover, present data suggest that the extent of the callosotomy may in uence the patient's performance.

Eslicarbazepine acetate as adjunctive treatment in partial-onset epilepsy.

OBJECTIVE: The aim of the study was to assess the clinical response to eslicarbazepine acetate (ESL) as add-on therapy in adult patients with partial-onset epilepsy by means of the time-to-baseline seizure count method. METHODS: We retrospectively identified consecutive patients with partial-onset seizures, with or without secondary generalization, prescribed to ESL add-on therapy. The primary endpoint was the time-to-baseline monthly seizure count. Subgroup analysis was performed according to carbamazepine (CBZ)/oxcarbazepine (OXC) status (prior vs never use). Secondary outcomes were the rate of treatment-related adverse events (AEs) and the AEs affecting ≥5% of patients. RESULTS: One-hundred and eighteen patients were included. The median time-to-baseline monthly seizure count was 46 (35-101) days in the overall study cohort. The number of concomitant anti-epileptic drugs (AEDs) was associated with the time-to-endpoint (adjusted hazard ratio [adj HR]=2.22, 95% CI 1.18-4.14, P=.013 for two AEDs vs one; adj HR=3.65, 95% CI 1.66-8.06, P=.001 for three or more AEDs vs one). Groupwise, the median times-to-baseline seizure count were 47 (35-97) and 43 (34-103) in patients with prior and never exposure to CBZ/OXC, respectively (P for log-rank test=.807). Adverse events occurred in 53.4% (63 of 118) of patients; the most frequently reported were dizziness (13.6%), somnolence (11.9%), nausea (6.8%), and fatigue (5.1%). CONCLUSIONS: Add-on ESL improved seizure control and was overall well-tolerated in adult patients with partial-onset epilepsy.

Further evidence for the topography and connectivity of the corpus callosum: an FMRI study of patients with partial callosal resection.

BACKGROUND AND PURPOSE: This functional MRI study was designed to describe activated fiber topography and trajectories in the corpus callosum (CC) of six patients carrying different degree of partial callosal resection. METHODS: Patients receiving gustatory, tactile, and visual stimulation according to a block-design protocol were scanned in a 1.5 Tesla magnet. Diffusion tensor imaging (DTI) data were also acquired to visualize spared interhemispheric fibers. RESULTS: Taste stimuli evoked bilateral activation of the primary gustatory area in all patients and foci in the anterior CC, when spared. Tactile stimuli to the hand evoked bilateral foci in the primary somatosensory area in patients with an intact posterior callosal body and only contralateral in the other patients. Callosal foci occurred in the CC body, if spared. In patients with an intact splenium central visual stimulation induced bilateral activation of the primary visual area as well as foci in the splenium itself. CONCLUSION: Present data show that interhemispheric fibers linking sensory areas crossed through the CC at the sites where the different sensory stimuli evoked activation foci, and that topography of callosal foci evoked by sensory stimulation in spared CC portions is consistent with that previously observed in subjects with intact CC.

Emergency room access for recurring seizures: when and why.

BACKGROUND AND PURPOSE: To develop a hypothetical model identifying potentially modifiable predictive factors of Emergency Room (ER) visits by patients suffering from drug resistant epilepsy. METHODS: During a 1-year period, all adult drug resistant patients followed by the same epileptologist were recruited after the occurrence of one or more epileptic attacks. They were divided into two groups based on whether they went to the ER after seizures. A prospective comparative analysis of the clinical and social characteristics of the two groups was performed in order to identify independent predictors of ER visits. Logistic regression analysis was used to confirm the potential predictive role of the evaluated variables. RESULTS: Logistic regression analysis confirmed the potential role in predicting ER visits for these variables: foreign nationality, current psychiatric therapy, current antiepileptic drug polytherapy, comorbidities, more than one episode in the same day and changes in usual seizure pattern. A relevant association was also found between the frequency of ER neuroimaging use and the following variables: occurrence of episodes on holidays or weekends, current antiepileptic drug monotherapy, multiple comorbidities and brain injury after seizure. CONCLUSIONS: The present study evaluated factors, some potentially amenable to change, related to drug resistant epileptic patients' ER visits following a seizure. This information may serve to improve the clinical and therapeutic management of patients, decrease the need for urgent care and reduce subsequent patient stress and related costs.

[Contrast media in urogenital radiology].

BACKGROUND. Contrast media are widely used in urogenital radiology. The ideal contrast agent should be totally inert, causing no interactions with organism, and with a rapid and complete excretion. Adverse reactions could occur after using any type of contrast media. Contrast enhanced procedures are performed with increasing frequency and the patients population is progressively older and with multiple co-morbid conditions, thus contrast media toxicity is becoming a serious problem. Contrast media-induced nephropathy (CIN) is considered an important cause of hospital-acquired renal failure. The administration of gadolinium-based contrast agents has been recently associated with the development of a serious adverse reaction, potentially lethal in patients with renal insufficiency, named nephrogenic systemic fibrosis (NSF). METHODS. Literature review on contrast media in urogenital radiology, CIN, NSF. CONCLUSIONS. Since 1996, the Contrast Media Safety Committee of the European Society of Urogenital Radiology (ESUR) has released its guidelines regarding safety about the use of contrast media. CIN, and the emerging NSF, are topics of increasing interest for urologists, radiologists, nephrologists, dermatologists and all the clinicians. Contrast media have progressively become safer in the last years. Even if rare, some adverse reactions still occurr up to now. CIN and its prevention remain an issue under debate. In the past, whenever a patient required a contrast-enhanced imaging study, the trend was to select magnetic resonance imaging with gadolinium-based contrast agents in order to avoid the well-known CIN of iodinated-based contrast agents. The awareness of NFS is changing the contrast-enhanced imaging in patients with renal failure. At present we have to investigate NSF etiopathogenesis, in order to prevent and eventually to cure it. The understanding of the risk factors for both CIN and NSF is an emerging need, the adoption of all preventive measures to reduce the risks remain a mandatory issue.

Divided visuo-spatial attention systems with total and anterior callosotomy.

The role of the corpus callosum in the inter-hemispheric integration of the visuo-spatial attention system, was investigated in patients with a total callosotomy or with an anterior callosal section. Subjects produced simple reaction times (RTs) to visual targets shown to the left or right visual hemifield. Preceding the target by an interval of 500 ms, arrow cues predicting the target location were shown left and right of the point of ocular fixation. For a majority of total and anterior callosotomy patients, results with valid focused cues (both arrows pointing to the target location) and with divided-attention cues (arrows pointing away from fixation) did not differ and both conditions produced shorter RTs than with neutral cues (equal signs). In contrast, neurologically intact subjects showed equal RTs with divided-attention and neutral cues, whereas valid focused cues produced reduced RTs relative to neutral cues. These results indicate that most split-brains, in contrast to normal observers, are capable of directing their attention to left and right visual field locations simultaneously, and therefore that each cerebral hemisphere controls its own visuo-spatial attention mechanism.

Callosal and cortical contribution to procedural learning.

Acallosal and callosotomized subjects usually show impairments on tasks requiring bilateral interdependent motor control. However, few studies have assessed the ability of these subjects to learn a skill that requires the simultaneous contribution of each hemisphere in its acquisition. The present study examined whether acallosal and callosotomized subjects could learn a visuomotor skill that involved a motor control from either both or a single hemisphere. Eleven adult patients, six acallosal and five callosotomized, participated in this study. Seven of these patients had epileptic foci located in the frontal and/or temporal areas and one of the acallosal patients showed bilateral prefrontal atrophy following surgical removal of an orbitofrontal cyst. The performance of the experimental subjects was compared with that of 11 matched control subjects, on a modified version of a serial reaction time task developed by Nissen and Bullemer (Cogn Psychol 1987; 19: 1-32). This skill acquisition task involved bimanual or unimanual key-pressing responses to a sequence of 10 visual stimuli that was repeated 160 times. A declarative memory task was then performed to assess explicit knowledge of the sequence. None of the experimental subjects learned the task in the bimanual condition. Patients with frontal epileptic foci or orbitofrontal damage also failed to learn the task in the unimanual condition when they were using the hand contralateral to the damaged hemisphere. All other subjects, including the acallosal and callosotomized patients with temporal foci, learned the visuomotor skill as well as their controls in the unimanual condition. In spite of the absence of transfer and interhemispheric integration of procedural learning, some of the acallosal and callosotomized patients were able to learn the sequence explicitly. These findings indicate that the corpus callosum and the frontal cortical areas are important for procedural learning of a visuomotor skill. They also confirm the dissociation described by Squire (Science 1986; 232: 1612-9 and J Cogn Neurosci 1992; 4: 232-43) between the declarative and procedural memory systems and extend this dissociation to processes involving simultaneous bihemispheric co-operation.

Depression after stroke: an investigation through catamnesis.

BACKGROUND: In the early stage of stroke, depression appears to be linked to certain brain areas. The study evaluated the importance of the side of the lesion in depressed patients 3 years after their first stroke. METHOD: Patients who had suffered a stroke and been discharged after rehabilitation were identified by hospital records. We interviewed 180 patients at home. Demographic as well as socioeconomic data were collected. The North-western University Disability Scale, the Beck Depression Inventory (BDI), the Relatives' Stress Scale, and the Social Dysfunction Rating Scale were applied. The diagnosis was confirmed for each patient by a clinical assessment according to the ICD-10 criteria. Patients with previous psychiatric treatment, comprehension problems, or severe hemi-inattention were excluded. RESULTS: By using a score of 14 on the BDI as a cutoff, 62 patients (34%) proved to be affected by depressive disorders. Clinical records showed that the location of the lesion was in the right hemisphere for 37 patients and in the left hemisphere for 25 patients. Statistical analysis of the mean scores obtained in this subgroup of depressed patients showed (1) no significant relation between depression and the hemispheric location of the lesion or between depression and level of education; (2) relation between BDI score and social activities; and (3) stress on the relatives that was mainly dependent on both the disability of the patients and their loss of social activities, whereas depression played a minor role. CONCLUSION: A high percentage of patients have depressive disorders 3 years or more after the stroke, independent of the side. Such mood disorders worsen the relationship between the disabled patients and their relatives and worsen leisure independent of the affected hemisphere.

Modifications in morphology of epileptic seizures after callosotomy.

The callosotomy on drug-resistant epileptic seizures may abolish or reduce their frequency and may modified the morphology of different kind of seizures. Our series is composed of 36 patients. Drop-attacks and complex partial seizures (CP) were present in all patients, generalized tonic-clonic seizures (GTC) in 16 (44.4%) and simple partial seizures (SP) and myoclonic attacks (MY) in 6 patients each. We found two kinds of modifications: a) lateralization of hypotonia which becomes hemisomatic, with lateral bending to the hypotonic side; b) different way of falling, due not only to the lateralization of hypotonia but also to the gradual impairment of muscle tone. Modifications in CP mainly concerned automatisms, which disappeared in 39.1% of patients, while 34.8% of them had a significant reduction in automatisms; this reduction consisted in simplification of automatic movements and in shorter duration of seizures.

EEG Patterns after callosotomy.

In 36 patients with drug-resistant epilepsy submitted to anterior callosotomy (27 cases), to two-stage total callosotomy (8 cases) and to posterior callosotomy (1 case) the EEG variations concerning background activity, focal activity and sharp-waves (SW) bisynchronous activity were evaluated. EEG modifications observed after callosotomy are the following: background rhythm tends to be better organised as spectral analysis demonstrated, this finding usually coincide with reduction of bisynchronous discharges. It appears that improvement in background activity cannot be correlated with outcome, but it seems to be to some extent since at the same time cognitive functions also seem to improve; however, this last aspect need to be checked in much larger series. The number and location of EEG foci do not change, but they appear to be more active; this is likely to depend only on the concomitant reduction of bisynchronous activity. No correlation seems to exist between the number and the location of foci, which are generally multiple. Lateralization of bisynchronous discharges as well as the reduction of their frequency and duration were observed. However, the clinical course is quite different: in some patients we have achieved good clinical responses in others postoperative results were poor. Lateralization of bisynchronous discharges is never absolute, on the grounds that in prolonged recordings bisynchronous discharges are nearly always present. Bisynchronous discharges in some cases are alternatively predominant in both hemispheres even within minutes or seconds. It was observed that after certain time, generally some months, lateralized discharges tend to generalize again, confirming that corpus callosum is replaced in discharge diffusion by other structures (brain-stem, diencephalon).

A crossover, controlled study comparing pergolide with bromocriptine as an adjunct to levodopa for the treatment of Parkinson's disease.

A single-blind, crossover study was carried out to compare the efficacy and safety of pergolide against that of bromocriptine in 57 patients with Parkinson's disease who showed a declining response to levodopa therapy. Patients were randomly assigned to receive either bromocriptine followed by pergolide, or pergolide followed by bromocriptine. Both drugs were administered for 12 weeks. Patients were assessed by a clinician blinded to treatment assignment using the New York University Parkinson's Disease Scale. The average daily dose of pergolide was 2.3 +/- 0.8 mg and of bromocriptine 24.2 +/- 8.4 mg. Addition of pergolide or bromocriptine resulted in a significant improvement in total scores when compared with the previous treatment of levodopa alone (pergolide, p = 0.0001; bromocriptine, p = 0.0005). Pergolide was more effective than bromocriptine in daily living scores (p = 0.02) and motor scores (p = 0.038). No differences in the incidence of dyskinesias, dystonias, or psychosis were observed between groups. Fewer adverse events were recorded in the pergolide group, and most patients and physicians preferred pergolide to bromocriptine. Pergolide as adjunctive therapy to levodopa was more effective than bromocriptine in this short-term trial.

Brain involvement in myotonic dystrophy: MRI features and their relationship to clinical and cognitive conditions.

A prospective, case-control study was carried out on 25 patients with myotonic dystrophy (MyD) and 25 healthy subjects using brain magnetic resonance imaging (MRI). The frequency and severity of white matter hyperintense lesions (WMHL) and brain atrophy in MyD patients were compared with their clinical features and cognitive impairment using an extensive neuropsychological battery. Eighty-four per cent of MyD patients showed WMHL, compared with 16% of controls (p < 0.0001). These lesions involved all cerebral lobes, without hemispheric prevalence. Twenty-eight per cent of MyD patients also showed particular WMHL at their temporal poles. Myotonic patients had significantly more cortical atrophy than controls. No relationship between atrophy and WMHL was found on the MRI scans. The extent of brain abnormalities (WMHL or atrophy) was not correlated to age, disease duration, physical disability or severity of neuropsychological impairment. Central nervous system abnormalities revealed by MRI appear to be an almost constant feature of MyD, but they are not found to be related to clinical or cognitive parameters. Their nature is still unclear: some of them, located at the temporal poles, seem to be characteristic of the disease, while others small, diffuse WMHLs, similar to the age related alterations revealed by MRI occurring during young and adult age in MyD patients.

Pergolide compared with bromocriptine in Parkinson's disease: a multicenter, crossover, controlled study.

We compared the efficacy and safety of pergolide and bromocriptine in 57 patients with Parkinson's disease (PD) with a declining response to levodopa therapy in a single-blind, crossover study. Patients were placed randomly on the sequence bromocriptine-pergolide (12 + 12 weeks) or vice versa. Regular evaluations using the New York University Parkinson's Disease Scale were performed by a clinician blinded to treatment assignment. Patients' and clinicians' impressions also were recorded. The average daily dose of pergolide was 2.3 +/0- 0.8 mg, and that of bromocriptine was 24.2 +/- 8.4 mg. Significantly greater efficacy was demonstrated by both drugs as adjunctive therapy to levodopa compared with previous treatment of levodopa alone (pergolide, p = 0.0001; bromocriptine, p = 0.0005; Wilcoxon t test). Pergolide was more effective than bromocriptine in daily living scores (p = 0.020) and motor scores (p = 0.038). No difference in dyskinesias, dystonias, and psychosis was observed. Adverse events were more frequent in bromocriptine-treated patients. Most patients and physicians preferred pergolide to bromocriptine. Pergolide as adjunctive therapy to levodopa was more effective than bromocriptine in this short-term trial.

The influence of depression, social activity, and family stress on functional outcome after stroke.

BACKGROUND AND PURPOSE: This study was designed to assess the quality of life after an active poststroke period of rehabilitation and to investigate the possibility of a return to a working environment for those still of working age. METHODS: The study was conducted on 180 consecutive patients affected by stroke who were hospitalized for the first time and discharged at least 1 year before the study. The group consisted of 65% men and 35% women with a mean age 65.29 years (SD, 11.22). The period between the stroke and the interview ranged from 12 to 196 months, with a mean of 37.5 months. The average Rankin score on discharge from the rehabilitation center was 2.718 (moderate handicap). The interview took place at home after consent obtained by telephone. The questionnaire included general and personal information regarding the individuals, their socioeconomic position, and scales for daily activity, depression, social activity, and stress produced in the family. The control group consisted of 167 age-matched subjects. RESULTS: A close correlation was observed in all patients between depression, social activity, and stress caused to relatives. The scores on the individual scales were clearly worse than those for control subjects. The patients received approximately 5 months of rehabilitation after the stroke. Differences emerged between men and women for depression and social activities, with the women scoring worse. In reference to daily life, 70% of prestroke ability was required on average after rehabilitation. The daily activity score at the time of the interview was also strongly influenced by the discharge score. The majority of patients were retired. Of the total, 20.64% returned to work, but not always to the same job and often after readapting to new conditions. Of this population, only 31.5% were women. With regard to the population aged younger than 65 years, 21.42% returned to work. Lesions in the dominant hemisphere do not necessarily seem to rule out return to work, even if associated with aphasia. The main discriminating element was the ability to understand language. The patients were often criticized by their cohabitants; the criticisms most often raised concerned apathy, irritability, and self-centeredness. Sexual activity was depressed in almost all cases. CONCLUSIONS: Despite the progress made in studying cerebral vasculopathies, patients in the aftermath of a stroke still seem to live unsatisfactorily, as they did many years ago. Useful measures include valid treatment against spasticity, psychological assistance, and greater social support.
