In 1952, renal cell carcinomas had been divided into 2 categories—clear cell or granular cell—depending upon their cytoplasmic staining characteristics. In the following years, the inventory of renal epithelial tumors has expanded by the addition of tumors named by their architectural pattern (i.e., papillary RCC, tubulocystic RCC), anatomic location (i.e., collecting duct carcinoma, renal medullary carcinoma), associated diseases (i.e., acquired cystic disease-associated RCCs). With the extensive application of molecular diagnostic techniques, it becomes possible to detect genetic distinctions between various types of renal neoplasm and discover new entities, otherwise misdiagnosed or diagnosed as unclassified RCC. Some tumors such as ALK rearrangement-associated RCC, MiT family translocation renal carcinomas, SDH-deficient renal cancer or FH-deficient RCC, are defined by their molecular characteristics. The most recent World Health Organization (WHO) classification of renal neoplasms account for more than 50 entities and provisional entities. New entities might be included in the upcoming WHO classification. The aim of this review is to summarise and discuss the newly acquired data and evidence on the clinical, pathological, molecular features and on the prognosis of new RCC entities, which will hopefully increase the awareness and the acceptance of these entities among clinicians and improve prognostication for individual patients. 相似文献

This retrospective cohort study regarding hair removal procedures considers all the data collected in three different clinical centers from 2017 to 2019. The device used to perform the treatments was composed of an Alexandrite 755 nm and an Nd:YAG 1064 nm laser, that delivered both wavelengths in a blended simultaneous emission (Thunder MT, Quanta System, Samarate, Italy). The improvement evaluated after five sessions of treatment by an external referee was: 83.0% for armpits, 82.1% for the bikini line, 82.2% for legs, 79.6% for thorax, and 81.6% for the back. The collected temporary skin reaction data reported in this study were all acceptable and transitory resolving in less than 1 week. The level of erythema and perifollicular edema were all signs of the reached treatment endpoint. First degree burns, hyper, and hypopigmentation were also reported in a few cases but these, all resolved before the follow‐up visit without any permanent skin effects. No adverse effects were thus reported to have happened. This retrospective study demonstrates the efficacy of combining Alexandrite and Nd:YAG lasers in a mixed modality with simultaneous emission. This technology permitted to treat patients with skin types I‐V without any reported permanent side effects and with a high pain tolerability compared to the use of Nd:YAG in single mode. 相似文献

The number of patients returning to dialysis after graft failure increases. Surprisingly, little is known about the clinical and immunological outcomes of this cohort. We retrospectively analyzed 254 patients after kidney allograft loss between 1997 and 2017 and report clinical outcomes such as mortality, relisting, retransplantations, transplant nephrectomies, and immunization status. Of the 254 patients, 49% had died 5 years after graft loss, while 27% were relisted, 14% were on dialysis and not relisted, and only 11% were retransplanted 5 years after graft loss. In the complete observational period, 111/254 (43.7%) patients were relisted. Of these, 72.1% of patients were under 55 years of age at time of graft loss and only 13.5% of patients were ≥65 years. Age at graft loss was associated with relisting in a logistic regression analysis. In the complete observational period, 42 patients (16.5%) were retransplanted. Only 4 of those (9.5%) were ≥65 years at time of graft loss. Nephrectomy had no impact on survival, relisting, or development of dnDSA. Patients after allograft loss have a high overall mortality. Immunization contributes to long waiting times. Only a very limited number of patients are retransplanted especially when ≥65 years at time of graft loss. 相似文献

Can a delusional idea be contagious? This question may seem paradoxical when we know that the very definition of delirium correspond to “an erroneous belief (…) maintained despite the very generally shared opinion” (DSM4) and so implies that peers do not share the beliefs expressed by the subject. However, cases of collective delirium have been described for many years, and have been the subject of numerous scientific publications since the 19th century. Among them, an entity emerged : “folie à deux”, in which a primary active subject could induce his delusions to a secondary subject, more vulnerable, said induced and passive. In 1877, Lasègue and Falret first introduced the term “folie à deux” and proposed the diagnostic criteria. They describe nine essential criteria among which, three would be the sine qua non conditions that can allow the outbreak of a delirium shared by two. They are the presence of an active element of superior intelligence, the existence of a common life between the two individuals, sufficiently long and intimate and a “closed and isolated” environment. These criteria were subsequently supplemented to arrive at the current definitions of induced delusional disorder (ICD10) and shared psychotic disorder (DSM4). This rare disorder has been the subject of numerous publications. However, these publications were often divided over both its epidemiology, its diagnostic criteria, and the specific treatment to be offered. The two recent definitions resulting from current classifications can also illustrate this dichotomy on certain criteria, beyond the very semantics which here oppose the terms “induced delusional” and “shared psychosis”. Moreover, this disorder has the particularity to question its real existence as it is currently challenged in the new classifications of the DSM V and ICD 11. We can therefore see that if the subject fascinates, it divides. What is it really? Can a delirium really be transmitted? Can a psychosis really be shared? And if so, is one of the two definitions more suitable to describe this disorder? What future can we imagine for this pathology? During the hospitalization of a patient for a “délire à deux”, concerning two persons from two different families sharing a delirium of filiation, we observed the current issues around this disorder and we asked ourselves which treatment to administer to these patients. The hospitalization took place over two stages: the first stage to understand the disorder, the second one to treat it. À family interview was conducted in the presence of the dyad of patients, to explore the interactional elements together, and establish the diagnosis. A preliminary step essential to therapeutic work on the question of loyalty and differentiation. This clinical case recalls the value of an integrated approach based on the systemic epistemology, both for the diagnostic phase than during therapeutic support. The objective of this work is to study, through an atypical clinical case and a review of recent literature, the different diagnostic, therapeutic and evolutionary perspectives of this particular pathology. 相似文献
