A diagnostic conundrum in Bardet-Biedl syndrome: when genetic diagnosis precedes clinical diagnosis.

Summary: Bardet-Biedl syndrome (BBS) is a rare, autosomal recessive, multisystem non-motile ciliopathy of progressive onset. It is primarily characterised by rod-cone dystrophy, early-onset obesity and related complications, postaxial polydactyly, renal and genitourinary abnormalities, learning disabilities, and hypogonadism. The diagnosis is based on Beales' modified diagnostic criteria.

Isomorphic (Koebner) Phenomenon Induced by Insulin Analogue Injections in Psoriasis.

Koebner phenomenon is an uncommon skin-related complication of subcutaneous insulin injection in patients with diabetes mellitus. This reaction, also referred as isomorphic phenomenon, has previously been described in various conditions including vitiligo, lichen planus, and psoriasis. We report a 56-year-old woman insulin-treated patient with type 2 diabetes mellitus who developed new-onset, sharply well-demarcated erythematous scaly plaques at the insulin injection sites consistent with Koebner phenomenon.

Exploring a New Entity of Single-Agent Pembrolizumab-Associated Hypophysitis.

Hypophysitis is the inflammation of the pituitary gland primary or secondary to local or systemic disease. It tends to occur more with cytotoxic T-lymphocyte-associated protein 4 inhibitors (10-15% of cases), which is a different entity compared to that associated with anti-program death 1 (anti-PD1) inhibitors. We describe a case of pembrolizumab-associated hypophysitis and conduct a systematic review of the literature.

Lipohypertrophy Monitoring Study (LIMO): Effect of single use of 4 mm pen needles combined with education on injection site rotation on glycaemic control: Confirmation of an unpleasant truth.

Aims: To investigate whether single use of 4 mm needles combined with education about injection technique and lipohypertrophy affects HbA1c, hypoglycaemia and glucose variability.

Methods: Insulin-injecting people with diabetes recruited from nine Belgian diabetes centres were prospectively followed for 6 months. They were provided 4 mm pen needles and education concerning injection technique using an online platform (BD and Me™) based on the international Forum for Injection Technique & Therapy Recommendations focused on avoidance of lipohypertrophy zones and reduction of needle reuse.

Nonmosaic Isodicentric Y Chromosome: A Rare Cause of Azoospermia- From Genetics to Clinical Practice.

Azoospermia is diagnosed when no spermatozoa can be detected after centrifugation of seminal fluid on at least two separate occasions. A number of genetic disorders can be related to nonobstructive azoospermia, and in up to 15% of azoospermic males, a genetic disorder is diagnosed. A 36-year-old male with nonobstructive azoospermia was referred to our department of diabetes and endocrinology due to an aberrant testicular biopsy.

Olfactory neuroblastoma (esthesioneuroblastoma) presenting as ectopic ACTH syndrome: always follow your nose.

Summary: ACTH-dependent hypercortisolism is caused by an ectopic ACTH syndrome (EAS) in 20% of cases. We report a rare cause of EAS in a 41-year-old woman, presenting with clinical features of Cushing's syndrome which developed over several months. Biochemical tests revealed hypokalemic metabolic alkalosis and high morning cortisol and ACTH levels.

Testicular Vein Sampling Can Reveal Gonadotropin-Independent Unilateral Steroidogenesis Supporting Spermatogenesis.

Suppressed gonadotropins combined with high-normal serum testosterone concentrations in oligozoospermic men suggest either use of exogenous testosterone or presence of a testosterone-producing tumor. We describe the case of a 31-year-old man referred for primary infertility. Gonadotropins were undetectably low, but testosterone and estradiol were in the high-normal range.

Sustainable improvement of HbA and satisfaction with diabetes care after adding telemedicine in patients on adaptable insulin regimens: Results of the TeleDiabetes randomized controlled trial.

This 2-year study evaluates whether tele-education adds to improvement and maintenance of good glycemic control and patient satisfaction. Adult patients were randomly assigned to study, getting immediate access to tele-education, or control group, getting this surplus education after 3 months. At several moments, clinical data were retrieved and patients completed questionnaires.
