Histoplasmosis capsulatum is a dimorphic fungus, recognised for its endemic presence in multiple global regions. It may cause severe opportunistic disseminated infection in immunocompromised individuals. This is a case report of a 33-year-old man from Thailand who was admitted at a Danish hospital with fever, weight loss, cough, nosebleeds, and newly diagnosed HIV. The clinical condition rapidly deteriorated with lung and kidney failure. The patient was diagnosed with H. capsulatum fungaemia first detected on blood smear. He was treated with intravenous amphotericin B followed by oral itraconazole as well as antiretroviral therapy.

Over the past decade, treatment with immune checkpoint inhibitors (ICI) has been implemented in cancer treatment. It has led to a significant improvement in the prognosis for many types of cancer. ICIs work by inducing the body's immune response against cancer cells. Unfortunately, they can also cause immune-related adverse events in most organ systems, with skin-related adverse events being among the most common. This review provides an overview of existing evidence and clinical experience regarding managing dermatological adverse events associated with ICIs.

Primary hyperparathyroidism (PHPT) is the most prevalent cause of hypercalcaemia, affecting 0.3% of the population. The only curative procedure is parathyroidectomy. Ectopic adenomas are challenging to localize and frequently result in persistent PHPT. This is a case report of a 29-year-old male patient who was diagnosed with PHPT prior to neck surgery and reoperated with bilateral neck exploration. However, the PHPT was not cured, until diagnostic CT with contrast had helped localizing a 1 cm ectopic parathyroid adenoma in the right horn of the thymus gland. The adenoma was then removed successfully.

Person-centered care and user involvement have gained focus in the public welfare agenda, as well as in the health sector. However, it has become clear that there is a bias in favor of resourceful citizens in the organisational user involvement. This bias can enhance disparities in health and social care. In this review, reasons that may underlie the bias in organisational user involvement are elucidated, and examples of ways to create more inclusive user involvement are given.

Current guidelines recommend screening with serum M-protein and serum-free light chain analysis (S-FLC) when an M-protein-related disorder is suspected. Many patients with multiple myeloma will be overlooked if only serum M-protein is measured. Despite this, the general practitioners in some areas of Denmark cannot order S-FLC. This review aims to disseminate knowledge of the S-FLC analysis, its applicability, and limitations in the diagnostic workup for suspected monoclonal gammopathies.

This case report details a rare case of contraceptive implant migration in a young woman. The migration was discovered three years post-insertion during a routine replacement visit. Despite the absence of pulmonary symptoms, a CT scan revealed the implant in the inferior lobe of the right lung. The patient was referred for further evaluation, but immediate surgical removal was deferred. This case report highlights the importance of healthcare providers recognising migration as a rare complication during implantation and suggests self-examination as a potential preventive strategy.

Communicating with scientific journals is a central part of the publication process, yet sparsely covered in the medical literature. A cover letter to the editor(s) should always accompany new submissions, whereas response (or rebuttal) letters relate to revisions and replying to referees' comments following peer review. This review describes the two types of letters, focusing on content, style, and structure, and provides helpful tips for handling challenging reviewer scenarios.
