Sex differences in presentation of pheochromocytoma and paraganglioma.

Purpose: The aim of the study was to investigate sex differences in presentation of pheochromocytomas and paragangliomas (PPGLs).

Methods: This is a retrospective cohort study including 183 patients with confirmed PPGL (females n=100, pheochromocytoma n=156) between year 2005 and 2023, attending Department of Endocrinology, Karolinska University Hospital, Stockholm. The collected data included the mode of presentation, symptoms, biochemical, genetic and histopathological test results.

Delayed Diagnosis of Retronychia: How Ultrasound Can Nail the Diagnosis in Clinically Subtle Patients.

A 47-year-old man presented to the dermatologic surgery clinic with a 7-month history of a painful, swollen left great toe after minor trauma. Intermittently, the toe became exquisitely tender such that even weight of a blanket exacerbated pain. The patient initially presented to primary care with purulence and pain, but the culture of expressed purulence revealed normal flora.

Blue-black hyperpigmentation on the extremities.

In some cases, diagnosis entails less "what is it?" and more "what caused it?"

Social media use in residency recruitment during the COVID-19 pandemic.

To investigate the extent to which dermatology programs use social media to connect with applicants, we conducted a search of all 140 residency programs on Instagram, Facebook, Twitter, and YouTube. Our search revealed 74 (53%) Instagram, 21 (15%) Facebook, 20 (14%) Twitter, and four (3%) YouTube accounts for dermatology programs, with the number of Instagram accounts increasing five-fold from the end of 2019 to present. Our results demonstrate that conditions created during the coronavirus disease 2019 (COVID-19) pandemic accelerated dermatology residency programs' acceptance of social media, particularly Instagram, as a means to communicate and share information with applicants.

Oral erosions associated with surreptitious marijuana vaping in an adolescent boy.

A 15-year-old boy presented with painful ulcerations affecting the oral mucosa that were eventually attributed to marijuana vaping. In this case report, we highlight cannabis vaping as a potential cause of oral erosions due to injury and chronic inflammation of the oral mucosa.

General expressions for downlink signal to interference and noise ratio in homogeneous and heterogeneous LTE-Advanced networks.

The interference is the most important problem in LTE or LTE-Advanced networks. In this paper, the interference was investigated in terms of the downlink signal to interference and noise ratio (SINR). In order to compare the different frequency reuse methods that were developed to enhance the SINR, it would be helpful to have a generalized expression to study the performance of the different methods.

Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome.

Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome, the most common periodic disorder of childhood, presents with the cardinal symptoms of periodic fever, aphthous stomatitis, pharyngitis, and adenitis typically before age 5. This review presents the recent literature on PFAPA and summarizes key findings in the pathogenesis, evaluation, and treatment of the disease. Theories surrounding the pathogenesis of PFAPA include a faulty innate immunologic response in conjunction with dysregulated T-cell activation.

New hybrid frequency reuse method for packet loss minimization in LTE network.

This paper investigates the problem of inter-cell interference (ICI) in Long Term Evolution (LTE) mobile systems, which is one of the main problems that causes loss of packets between the base station and the mobile station. Recently, different frequency reuse methods, such as soft and fractional frequency reuse, have been introduced in order to mitigate this type of interference. In this paper, minimizing the packet loss between the base station and the mobile station is the main concern.

Culturally informed views on cancer screening: a qualitative research study of the differences between older and younger Somali immigrant women.

Background: Somali women are infrequently screened for breast or cervical cancer, and there is a paucity of evidence-based interventions to increase cancer screening in this community. In order to create a culturally relevant intervention for Somali women living in Minnesota, we sought to understand what Somali immigrant women know about breast and cervical cancer, what are the attitudes toward screening and what cultural barriers are there to screen as well as cultural factors that would facilitate screening.

Methods: In partnership with a community-based organization, New American Community Services (NACS), focus groups were conducted to explore the issues described above.

A call to action: bold ideas from the Minnesota Women's Heart Summit.

Minnesota has the lowest overall coronary heart disease mortality rate in the United States. Yet disparities between men and women persist with regard to prevention, detection, and treatment. This has led to a gender gap not only in terms of care but also in survival rates.
