Sentinel lymph node biopsy based on anatomical landmarks and locoregional mapping of inguinofemoral sentinel lymph nodes in women with vulval cancer: an operative technique.

Inguinal lymph node involvement is the most robust predictor of mortality in vulval cancer and sentinel lymph node (SLN) biopsy is a safe diagnostic modality. We describe a technique based on anatomical landmarks. Our aims are (1) to describe the territorial mapping of SLNs, (2) to evaluate the associated complication rate vis-à-vis those reported in the literature, and (3) to assess its accuracy in detecting SLNs.

The role of preoperative computerized tomography (CT) scan of the pelvis and groin in the management of clinically early staged vulva squamous cell carcinoma.

Introduction: Vulvar squamous cell carcinoma (VSCC) commonly metastasises through groin lymphatics. However, the use of pre-operative imaging in detecting inguinal nodal metastasis before staging surgery or to triage patients for sentinel node biopsy remains unclear. Here, we investigated if pre-operative CT scan, the imaging choice in our cancer centre, influences the overall course of VSCC management in those patients without clinical evidence of groin lymphadenopathy.

CB1 receptor mediates the effects of glucocorticoids on AMPK activity in the hypothalamus.

AMP-activated protein kinase (AMPK), a regulator of cellular and systemic energy homeostasis, can be influenced by several hormones. Tissue-specific alteration of AMPK activity by glucocorticoids may explain the increase in appetite, the accumulation of lipids in adipose tissues, and the detrimental cardiac effects of Cushing's syndrome. Endocannabinoids are known to mediate the effects of various hormones and to influence AMPK activity.

Ghrelin in obesity and endocrine diseases.

Ghrelin shows orexigenic effect through its action on the hypothalamic appetite-regulating pathways, while in the periphery ghrelin increases adipose tissue accumulation and has a diabetogenic effect on the liver and pancreas. Adenosine monophosphate-activated protein kinase (AMPK) has been suggested as one of the mediators of ghrelin's effects. Plasma ghrelin levels are dependent on body mass index as well as food intake patterns.
