- Every 30 s, a lower limb is amputated due to diabetes. Of all amputations in diabetic patients 85% are preceded by a foot ulcer which subsequently deteriorates to a severe infection or gangrene. There is a complexity of factors related to healing of foot ulcers including strategies for treatment of decreased perfusion, oedema, pain, infection, metabolic disturbances, malnutrition, non-weight bearing, wound treatment, foot surgery, and management of intercurrent disease. Patients with diabetic foot ulcer and decreased perfusion do often not have rest pain or claudication and as a consequence non-invasive vascular testing is recommended for early recognition of ulcers in need of revascularisation to achieve healing. A diabetic foot infection is a potentially limb-threatening condition. Infection is diagnosed by the presence or increased rate of signs inflammation. Often these signs are less marked than expected. Imaging studies can diagnose or better define deep, soft tissue purulent collections and are frequently needed to detect pathological findings in bone. The initial antimicrobial treatment as well as duration of treatment is empiric. There is a substantial delay in wound healing in diabetic foot ulcer which has been related to various abnormalities. Several new treatments related to these abnormalities have been explored in wound healing with various successes. An essential part of the strategy to achieve healing is an effective offloading. Many interventions with advanced wound management have failed due to not recognizing the need for effective offloading. A multidisciplinary approach to wounds and foot ulcer has been successfully implemented in different centres with a substantial decrease in amputation rate.

- Metastases from ileal neuroendocrine tumors (NETs) to the myocardium are rare and generally seen in patients with widespread metastatic NET disease. The objectives of this investigation were to describe the frequency of intracardiac metastases in ileal NET patients examined by 68Ga-DOTA-TOC-PET/CT and to describe the cases in detail. All 68Ga-DOTA-TOC-PET/CT examinations performed at the Karolinska University Hospital since 2010 until April 2012 were reviewed. In all, 128 out of 337 examinations were in patients with ileal NETs. Four patients had seven myocardiac metastases, yielding a frequency of 4.3 % in patients with ileal NETs. One patient had cardiac surgery while three were treated with somatostatin analogs. The cardiac metastases did not affect the patients’ activity of daily life. 68Ga-DOTA-TOC-PET/CT is an established imaging modality in identifying cardiac metastases in ileal NETs. Prospective studies are needed to confirm the true clinical value of 68Ga-DOTA-TOC-PET/CT in detecting cardiac metastases in both ileal and non-ileal NETs.

- Clinically non-functional pituitary adenomas are often derived from gonadotropin producing cells. However, gonadotropinomas causing elevated serum levels of follicle-stimulating hormone (FSH) and clinical signs of FSH hypersecretion are very rarely described. Our patient, a 56-year-old man, was referred to our clinic with signs of hypogonadism. Magnetic resonance imaging (MRI) and biochemical examinations showed a large pituitary adenoma and excessive levels of serum FSH. Clinical examination and ultrasound measurement revealed bilaterally enlarged testes. After pituitary surgery, serum FSH levels normalized and there was a decrease in testicular volume. This case suggests that supraphysiological levels of FSH from a gonadotropinoma can cause a clinically observable effect, i.e. testicular enlargement. This is in line with experimental studies showing biological effect of FSH from pituitary adenomas and previous occasional reports of ovarian hyperstimulation and testicular enlargement in patients with FSH-secreting gonadotropinomas.

- Recently, correlations between corticotroph tumor dedifferentiation and both E-cadherin immunostaining and reduced mRNA expression of the E-cadherin gene (CDH1) have been demonstrated. The purpose of this study was to explore whether tumor dedifferentiation correlated with glucocorticoid resistance and whether the resistance was associated with both positively and negatively regulated genes. Tumor material from 20 patients with verified Cushing's disease or Nelson's syndrome operated on at Rikshospitalet, Oslo. Reverse transcription polymerase chain reaction analysis of genes such as E-cadherin (CDH1), proopiomelanocortin (POMC), glucocorticoid-induced leucine zipper (GILZ), and thioredoxin-interacting protein (TXNIP) was performed. The correlations between the expression of the GILZ, TXNIP, and POMC genes in different stages of corticotroph adenomas, the E-cadherin mRNA expression and staining pattern, and the preoperative 24-h cortisol excretion were examined. The GILZ and TXNIP expression levels were positively correlated to the CDH1 expression and were highest in microadenomas and in tumors with a high membranous E-cadherin reactivity. In contrast, the POMC expression was not significantly different between the groups. This divergence between the genes that were positively and negatively regulated by glucocorticoids could not be supported by other gene expression analyses. No correlations to urinary cortisol were found. The expression of the glucocorticoid-responsive genes POMC, GILZ, and TXNIP in corticotroph adenomas showed a remarkable variation. The pattern and variability of glucocorticoid resistance in corticotroph adenomas seem to correlate with a loss of the epithelial phenotype associated with corticotroph tumor dedifferentiation.

- To determine quality of life (QoL) in adult males with congenital adrenal hyperplasia (CAH). CAH males with 21-hydroxylase deficiency (n = 30), 19-67 years old, were compared with controls (n = 32). QoL was assessed using questionnaires on general living conditions and sexual issues, and the psychological well-being index (PGWB) form. Fewer CAH males than controls were students (3 vs. 25 %, P = 0.028) and more had blue-collar work (57 vs. 33 %, P = 0.023). Patients were less interested in sports (47 vs. 72 %, P = 0.034) and art/literature/film (10 vs. 47 %, P = 0.004). PGWB total score was 82.7 ± 13.7 versus 87.0 ± 11.1 (P = NS), but hydrocortisone/cortisone acetate treated scored lower than controls and prednisolone treated. Glucocorticoid over-treated had lower QoL than those with poor control (PGWB total score 77.1 ± 13.5 vs. 92.4 ± 11.1, P = 0.026) and controls (P = 0.025). Total PGWB score was positively correlated with adrenal androgens and steroid precursors. Subscale scores indicated that patients with late diagnosis were more depressive (12.1 ± 2.8 vs. 13.9 ± 1.4, P = 0.011) and had a lower self-control (11.3 ± 3.6 vs. 13.1 ± 1.0, P = 0.019) compared with controls. Sexual satisfaction was similar in spite of more patients being sexually inactive (27 vs. 6 %, P = 0.040). Adult CAH males differed from controls with respect to type of occupation and spare time interests but had similar QoL despite being less sexually active. Optimizing glucocorticoid therapy might further improve QoL. Some disadvantages found in patients diagnosed late will hopefully not be seen in patients diagnosed by neonatal screening, but this has yet to be studied.

- The key question answered by this study is whether it is possible to deliver a pharmacokinetic and pharmacodynamic duration of antidiuretic action long enough to ensure adequate antidiuresis with two daily administrations of desmopressin in patients with central diabetes insipidus (CDI). We studied the efficacy and safety of desmopressin i.v. in 13 CDI patients using two 3-way crossover designs, in the doses 30, 60, 125 ng, and 125, 250 and 500 ng. Duration of action, minimum output rate, max osmolality and average osmolality during action (AUC osmolality) were measured every 30 min for the first 2 h during the infusion, and then every hour or every second hour until the urine output rate was greater than 2 ml/kg/30 min. The duration of antidiuretic action was 4, 8 and 11 h, respectively, for 125, 250, and 500 ng, increasing from 250 to 500 ng but for the remaining secondary dynamic efficacy parameters no difference could be detected based on descriptive statistics between the doses 250 and 500 ng, indicating that the upper plateau region of the dose-response curve had been reached. All treatment emergent adverse events were classified as unrelated or unlikely related to trial medication. No serious adverse events occurred. Data on duration of action indicates that it is possible to achieve antidiuretic control with 500 ng i.v. corresponding to 160 mu g orodispersible tablets twice daily in CDI patients. Today, the Minirin Melt label recommends the majority of CDI patients a dose of 60 to 120 mu g t.i.d.

- Osteoporosis is a metabolic bone disorder affecting million of people worldwide. Increased understanding of bone disease has led to a greater recognition of factors affecting bones, and consequently many secondary causes of osteoporosis were demonstrated. In this study, we aim to explore possible causes of bone loss and fractures in subjects affected by chronic inflammatory disease and to suggest new targets for intervention. In fact several studies, evaluated to perform this study, suggest that the patients with chronic inflammatory disease could be at high risk for fractures due to bone loss as consequence of malnutrition, caused by inflammation and hormonal change. Consequently, some actions could derive from the considerations of these mechanisms: a change in actual approach of chronic patients, that may include the investigation on the possible presence of osteoporosis, as well as further research on this topic to find a better therapy to prevent osteoporosis considering all the mechanisms described. © 2012 Springer Science+Business Media New York.
