Operational tolerance in kidney transplantation is characterized by stable serum creatinine < 1.7 mg/dL and proteinuria < 1 g/day in the absence of immunosuppression or immunodeficiency for over one year. However, simultaneous donor specific antibodies are common and serum creatinine is a poor surrogate of early lesions. Consequently, subclinical rejections will meet operational tolerance criteria if serum creatinine remains stable. We report a patient with operational tolerance criteria followed by biopsy-proven chronic active antibody mediated rejection, discussing the intricate challenges of immunosuppression management.

Favre–Racouchot disease (FRD) is clinically characterized by the presence of open comedones, small papules, and cystic lesions with deep wrinkles and furrows on sun-exposed areas, especially the face. FRD is a purely cosmetic disorder, with most patients not requesting treatment. Dermoscopy may play a vital role in diagnosing early lesions of FRD, averting the need for an invasive procedure such as a skin biopsy, and helping to differentiate it from close mimics. The dermoscopic features of FRD have not been reported in the literature before. We report a clinicoepidemiological profile and dermoscopic findings in patients presenting with features suggestive of FRD.

Background The aim of this study is to investigate the clinicopathological features of intrinsic and extrinsic subtypes in adenomyosis. In particular, we focused on the early lesions of adenomyosis. Methods This is a single-center, prospective study of women who elected surgery for adenomyosis at the Department of Gynecology, Nara Medical University Hospital, Kashihara, Japan, from April 2008 to March 2018. Adenomyosis was histologically classified as intrinsic, extrinsic, and others, depending on the type of intramural growth. Adenomyosis that occurs at the inner and outer myometrium was defined as an intrinsic and extrinsic type, respectively. Results One hundred eighty-nine patients with histologically confirmed adenomyosis were classified into three different types, 74 intrinsic type, 78 extrinsic type, and 37 other type. Compared to the intrinsic type, the extrinsic type was more likely to have endometriosis, including ovarian endometrioma (OMA), superficial peritoneal endometriosis (SUP), or deep infiltrating endometriosis (DIE). To further identify the clinicopathological features of early-stage adenomyosis, we focused only on patients with intrinsic and extrinsic types of adenomyosis with less than one-third of muscular layer infiltration. Patients with early-stage intrinsic adenomyosis were more likely to experience induced abortions. Patients with early-stage extrinsic adenomyosis were more likely to have endometriosis. The coexistence of endometriosis and the lack of induced abortion were independent predictors of extrinsic adenomyosis. Multivariate logistic regression analysis identified coexistence of endometriosis as independent predictors of the early stage extrinsic adenomyosis. Conclusion The study suggests that there are at least two types of adenomyosis, where the intrinsic type is closely associated with a history of induced abortion, while the extrinsic type is strongly associated with endometriosis. Adenomyosis might be a gynecological disorder with complex pathogenesis implicating both traumatic and endometriotic factors.

High myopia continues to progress and the eye axis continues to grow, resulting in mechanical dilatation of the eyeball wall, and with the increase of age, resulting in a variety of myopic fundus pathological changes. Considering that in the late stage of fundus disease, patients can obviously feel the impact of the disease on vision, and ophthalmologists are needed for direct diagnosis, intervention and treatment. The impact of early lesions on vision is relatively weak, and patients can not detect the emergence of these lesions in time, which can only be found by fundus survey. Therefore, the automatic detection of early lesions of fundus disease (especially microaneurysms) is not only of great significance for early diagnosis and early treatment of fundus disease, but also a good reference for the detection of other fundus diseases. In this paper, color ultrasound can effectively analyze the origin of fundus diseases. The results showed that with the changes of age, eye axis and posterior sclera shape in high myopia, the area and range of myopic arc and choroidal atrophy arc expanded, the thickness of nerve fiber and choroid became thinner, and the fovea of macula mainly shifted vertically. In addition, it was also found that myopic arc, choroidal atrophic arc area, retinal thickness, nerve fiber thickness, choroidal thickness, vertical distance from macular fovea to optic disc center were correlated with age and eye axis.

The aim of this study is to report on the oral lesions detected in 123 patients diagnosed at the University Hospital of Bari from October 2020 to December 2020, focusing on the correlation of clinical and pathological features in order to purpose a new classification. Methods. General and specialistic anamnesis were achieved and oral examination was performed. The following data were collected: age/gender, general symptoms and form of Covid-19, presence and features of taste disorders, day of appearance of the oral lesions, type and features of oral lesions and day of beginning of therapies. If ulcerative lesions did not heal, biopsy was performed. Results. Many types of oral lesions were found and classified into four groups considering the timing of appearance and the start of the therapies. Early lesions in the initial stages of Covid-19 before the start of therapies was observed in 65.9% of the patients. In the histopathological analysis of four early lesions, thrombosis of small and middle size vessels was always noticed with necrosis of superficial tissues. Conclusion. The presence of oral lesions in early stages of Covid-19 could represent an initial sign of peripheral thrombosis, a warning sign of possible evolution to severe illness. This suggests that anticoagulant therapies should start as soon as possible.
