Background: Thymic neuroendocrine tumor as a cause of Cushing syndrome is extremely rare in children.

Case Presentation: We report a case of a 10-year-old girl who presented with typical symptoms and signs of hypercortisolemia, including bone fractures, growth retardation, and kidney stones. The patient was managed with oral ketoconazole, during which she experienced adrenal insufficiency, possibly due to either cyclic adrenocorticotropic hormone (ACTH) secretion or concurrent COVID-19 infection.

Article Synopsis
  • Adrenal insufficiency (AI) is a syndrome that can be classified as primary, due to damage to the adrenal glands, or secondary, caused by a lack of stimulation from the pituitary gland.
  • Diagnosis involves clinical evaluation and various biochemical tests that measure hormone levels and assess adrenal function.
  • Proper diagnosis and timely hormone replacement therapy are essential to manage AI and prevent serious complications like adrenal crises.

  • An online survey of European thyroid specialists revealed that 28% believe thyroid hormone (TH) treatment may be appropriate for euthyroid patients with growing simple goiters, despite guidelines against this practice.
  • There were significant regional differences in support for TH treatment, with only 7% in The Netherlands compared to 78% in the Czech Republic.
  • Factors influencing the likelihood of recommending TH included the specialist's age and the historical iodine insufficiency of their region, while gender, country, and economic factors showed weak associations.

  • Context
  • : Maternal diabetes negatively impacts the development of the fetal cardiovascular system, with an emphasis on the link between maternal glucose control and fetal heart structure/function.
  • Study Design
  • : A case-control study with 62 pregnant women with type 1 diabetes and 30 healthy controls assessed fetal heart measures in the second and third trimesters using various ultrasound techniques, while analyzing maternal glucose management over three gestational periods.
  • Findings
  • : Fetuses of diabetic mothers showed significant changes (e.g., increased heart dimensions and output) compared to controls, and certain fetal heart metrics were inversely related to poor glucose control and higher hemoglobin levels

Summary: Severe Cushing's syndrome from an ectopic adrenocorticotropic hormone-producing tumour is rare but often demands rapid diagnostics and treatment of hypercortisolism with its comorbidities. Pharmacotherapy of hypercortisolism by ketoconazole, metyrapone and osilodrostat is currently available. If unsuccessful or insufficient a bilateral adrenalectomy is an option.

  • The SARS-CoV-2 pandemic poses significant challenges for everyday life, especially for patients with multiple sclerosis (MS) who are vulnerable due to their treatments with disease-modifying therapies (DMTs).
  • Understanding vaccine effectiveness and safety for MS patients, especially regarding potential risks and neurological impacts, is essential since these patients might be at risk of disease relapses following infections.
  • Vaccination is recommended for MS patients not in an active disease phase, as it offers some protection despite concerns about reduced immune responses due to certain DMTs, and timing for vaccinations and DMT regimen is crucial for optimizing the vaccine's effectiveness.

Background: We report four pediatric subjects with Cushing's disease (CD) diagnosed in the Czech Republic. We focus on initial symptoms of Cushing's syndrome (CS) which can lead to early diagnosis, on typical symptoms of CS in children, their age and sex distribution, the mean length of symptoms prior to diagnosis, indication for examination, post-cure growth, sexual development and pituitary function in our four CD patients after transsphenoidal pituitary surgery (TSS). We describe the diagnostic process leading to confirmation of CD and we emphasize the biochemical and radiological diagnostic difficulties.

To determine the optimal week for labor induction in women with diet-controlled gestational diabetes mellitus by comparing differences in perinatal and neonatal outcomes of labor induction to expectant management at different gestational weeks. Methods: This was a retrospective analysis of a prospectively recruited cohort of 797 singleton pregnancies complicated by diet-controlled gestational diabetes mellitus that were diagnosed, treated, and delivered after 37 weeks in a tertiary, university-affiliated perinatal center between January 2016 and December 2021. Results: The incidence of neonatal complications was highest when delivery occurred at 37 weeks, whereas fetal macrosomia occurred mostly at 41 weeks (20.

Article Synopsis
  • Germany's 2030 oral health agenda emphasizes the need for key behaviors like regular toothbrushing and dental check-ups, prompting an investigation into the oral health knowledge, attitudes, and behaviors (KAB) of dental students.
  • A study surveyed 508 dental students, revealing high oral health KAB scores overall, with significant differences based on gender and clinical experience—clinical students scored higher than preclinical peers.
  • The results indicate that tobacco smoking is linked to poorer oral health KAB, suggesting a need for curriculum improvements that focus on preventive dentistry and better support for gender-diverse students in future studies.

  • - Despite advancements in medical care, pregnancies in women with type 1 diabetes mellitus (T1DM) face higher risks for both mothers and babies, highlighting the importance of optimal diabetes management before and during pregnancy to reduce complications.
  • - A study analyzing 221 pregnancies from 2008 to 2018 found that most women had inadequate diabetes compensation at conception; however, those with proper management before pregnancy had fewer perinatal issues.
  • - The findings suggest that women with T1DM should plan their pregnancies and seek proper medical guidance to improve outcomes, as planned pregnancies with good diabetes control result in fewer complications for both mother and child.
