Prostate biopsy is a very commonly performed office procedure leading to the diagnosis of the most prevalent solid-organ malignancy in American men. Although the transrectal technique for prostate biopsy remains the gold standard, there is increasing interest in the transperineal approach as it offers a clean, percutaneous approach that significantly decreases the risk for infection. In this review, we discuss emerging developments in transperineal prostate biopsy that may optimize the way biopsies are performed in clinical practice.

Similarly, to transrectal biopsy, the transperineal approach also allows for the performance of systematic and MRI-targeted biopsy cores. As transperineal biopsy obviates the translocation of rectal bacteria to the prostate or bloodstream, in contrast to transrectal biopsy, it is feasible to forgo peri-procedural antibiotics in accordance with professional guidelines. This may attenuate antimicrobial resistance that may be associated with augmented prophylaxis. In addition, although transperineal biopsy may be traditionally performed under general anesthesia using a template grid, it may also be performed freehand under local anesthesia or sedation. Avoiding prophylactic antibiotics and general anesthesia as well as reducing infections/hospitalizations for transperineal biopsy scaled nationally will likely result in significant healthcare savings.

Transperineal biopsy with combined systematic and MRI-targeted cores, offers several advantages over conventional transrectal biopsy. Transperineal biopsy under local anesthesia and without periprocedural antibiotic is emerging as a promising method for prostate cancer diagnosis and surveillance.

Whether Grade Group 1 (GG1) prostate cancer is really cancer remains controversial.

Favoring renaming GG1 with a noncancerous diagnosis are fear of the term cancer, which will lead to overtreatment of GG1; and indolence of GG1. Favor designating GG1 as cancer are morphologically, GG1 may be indistinguishable from GG2 to GG5 and GG1 is invasive (lacks basal cells), can show perineural invasion and extraprostatic extension; molecularly, GG1 has many of the hallmarks of prostate cancer; calling GG1 noncancer would lead to inconsistencies and confusion in reporting; sampling error with GG1 on biopsy can miss higher grade cancer; removing the label of cancer in men with GG1 on biopsy may make it challenging to insure follow-up during active surveillance; the prognosis of treated GG1 may not be the same if GG1 called noncancer and not treated; with Grade Group terminology, GG1 is more intuitive to patients as lowest grade cancer; and patients are increasingly adopting active surveillance, recognizing that not all prostate cancers are the same and GG1 can be followed carefully and safely on active surveillance.

There is strong support for retaining the carcinoma designation for GG1.

This scoping review will summarize what is known about formal and informal perinatal bereavement care guidelines used in health care facilities before discharge, and map the mental health outcomes of parents against characteristics of the guidelines.

Conflicting evidence for bereavement care guidelines, the lack of randomized controlled trials and experimental studies, and older synthesized information with a limited focus or population make synthesis complex. A scoping review will facilitate the process of determining the breadth and depth of the literature.

Sources pertaining to bereavement care guidelines used in health care facilities immediately after perinatal loss (miscarriage, stillbirth, or neonatal death) and measuring parents' mental health outcomes will be included. Sources relating to family members other than parents, perinatal loss occurring outside of a health care facility, and physical care guidelines will be excluded.

The proposed review will be conducted using JBI methodology for sure. Major databases to be searched will include CINAHL (EBSCO), PsycINFO (EBSCO), SocINDEX (EBSCO), Cochrane, Embase, MEDLINE (PubMed), and Web of Science. The earliest empirical study found (1976) will serve as the starting date limit. After pilot testing the two-step screening process (titles and abstracts, then full-text articles), data will be extracted, collated, and presented in narrative form as well as in tables and diagrams. The results will provide facilities with a broad view of bereavement care to support grieving parents' mental health.
The cryoballoon catheter has been an option for the treatment of atrial fibrillation for over a decade. The most widely used device is the Medtronic Arctic Advance cryoballoon catheter. Recently, Boston Scientific has released the POLARx cryoballoon catheter. Here we review the major changes in the catheter system's design and its implications for procedural practice.

The POLARx cryoballoon catheter has been approved for use in Europe. Some studies have been published detailing the first clinical experiences in vivo with this newest technology.

The changes to the POLARx cryoballoon catheter, particularly its ability to maintain balloon size and pressure, will improve occlusion and theoretically improve procedural outcomes.

Vasculitis describes a wide spectrum of rare, inflammatory, multisystem disorders. These heterogenous diseases all have inflammation of blood vessels as a central feature. However, they differ in terms of their genetic and environmental risk factors, disease pathogenesis, clinical presentations and treatment strategies. Many animal models of vasculitis exist, each resembling a different human clinical phenotype. This review provides an overview of recently published findings from experimental animal models of vasculitis.

Several new animal models have been described during the review period. New insights gleaned from existing animal models regarding cause, disease effector mechanisms and novel treatments identified in established animal models are discussed.

Animal models continue to be an important tool for understanding disease pathogenesis, especially in rare and complex diseases such as vasculitis. They also provide an invaluable platform for development and preclinical testing of new treatments.

Palisaded neutrophilic and granulomatous dermatitis (PNGD) represents a cutaneous histopathologic reaction spectrum associated with several underlying disorders. click here Few cases of PNGD have been associated with chronic myelomonocytic leukemia (CMML), a malignant hematopoietic disorder with features in between those of a myeloproliferative neoplasm and myelodysplastic syndrome. We present a patient with a generalized papular skin reaction involving the neck, chest, and shoulders with histomorphological features on the spectrum of PNGD. Subsequent laboratory workup demonstrated a persistent mild monocytosis, raising concern for CMML. link2 The diagnosis was ultimately confirmed with a bone marrow biopsy and associated mutational analysis through next-generation sequencing which identified deleterious variants in SRSF2, IDH2, and ASXL1. The findings in this case strengthen the previously made association between PNGD and SRSF2-mutated CMML and may help better define a unique recognizable clinical-histopathological-molecue clinical-histopathological-molecular subtype for dermatopathologists.
Pulse granulomas are uncommon reactions to vegetable exogenous matter characterized by the presence of hyaline rings. Although they are usually found in the oral cavity or along the gastrointestinal or respiratory tracts, there are a few cases described outside those regions. We present the first case of a granulomatous reaction with hyaline rings in the skin reaction after an accidental wound and suggest the term pulse granuloma-like to describe lesions that resemble pulse granulomas but with no connection to the gastrointestinal or respiratory tracts. Moreover, we provide a graphic comparison of the hyaline rings observed in our case and the histologic sections of some plants that could have been involved.

Granular cell tumors (GCTs) are rare soft tissue tumors of Schwann cell origin that manifest as papulonodular lesions and occur mainly in adults. The diagnosis is usually confirmed by histopathology. Most of GCTs are benign, but some lesions may exhibit malignant criteria. This study is a retrospective case series including all children with histopathologically documented multiple GCTs who attended the dermatology department of the university hospitals between February 2008 and March 2021. The objective of our study was to raise awareness to this unrecognized and rare entity in such age group. The study included 9 patients (6 girls and 3 boys) with multiple GCTs. Their age ranged between 5 and 13 years. The lesions were skin-colored to light brown, firm, smooth-surfaced nodules. Most of the lesions were on the extremities, and their mean diameter was 160.5 mm2. None of the lesions exhibited any malignant criteria on histopathology. No extracutaneous or mucosal lesions were detected. Dermatologists should belight brown, firm, smooth-surfaced nodules. Most of the lesions were on the extremities, and their mean diameter was 160.5 mm2. None of the lesions exhibited any malignant criteria on histopathology. No extracutaneous or mucosal lesions were detected. link3 Dermatologists should be aware of this rare condition in children because early recognition allows more conservative resection of the tumor and less invasive reconstruction of the defect. Our study highlights that multifocality does not necessarily indicate malignancy or other systemic comorbidities.
