Vulvar cancer is rare and accounts for only 5% of all gynecologic cancers. Squamous cell carcinoma is the most common and makes up 90% of the cases. Vulvar adenocarcinoma usually arises in Bartholin and other vulvar glands. Primary vulvar intestinal-type adenocarcinoma is an extremely rare disease with an unclear prognosis and treatment. Its origin is still unknown, the most accepted theory suggests cloacal remnants as the source of origin. Only a few cases have been reported in the literature. We present a case of a 66-yr-old female who presented with vulvar pruritus and local discomfort, showing a 2 cm tumor located in the left labium minor in the region of vulvar fourchette. Wide vulvar excision and bilateral lymph nodes dissection were performed. Other concomitant lesions and distant extension of tumor were ruled out by positron emission tomography. Pathologic study revealed a colonic-type adenocarcinoma with typical villoglandular architecture with an irregular glandular structure composed of atypical columnar epithelium. The lesion had direct contact with epidermal surface and mainly was external without involving the dermis. Immunohistochemical analysis revealed positive staining for cytokeratin 20 and CDX2. p16 showed an abnormal diffuse and strong immunoexpression. The presence of a low-risk human papillomavirus was detected by polymerase chain reaction, therefore, the expression of p16 cannot be explained in this case by the presence of human papillomavirus. Additional studies are needed to be performed in further cases to clarify the role of human papillomavirus in this kind of tumors.Although extremely rare, uterine damage after hysteroscopic myomectomy sets the precondition for various life-threatening placental attachment disorders like placenta percreta (PP) or scar pregnancy. Due to vast clinical similarities, these terms are often used interchangeably. We report a case of a 47-yr-old patient at 27 wk + 4 d of gestation who presented with rectal bleeding. Clinical history revealed a previous uterine posterior wall myomectomy. The patient received intensive diagnostic work-up including sonography and magnetic resonance imaging. Under the suspicion of a bleeding Meckel diverticulum, an emergency laparotomy was performed. Intraoperatively it was observed that the placental tissue infiltrated the small bowel intestine at the location of the previous myomectomy. The adjacent intestine and the infiltrating placenta were surgically removed. The placenta could be easily detached from the uterus, which is why no hysterectomy was performed. Retrospectively, no radiologic or clinical hints of PP or scar pregnancy were evident before the surgery. Moreover, the pathologic work-up carried out afterwards proved no histopathologic evidence for PP. Our case underlines several clinical and pathologic difficulties. First, invasive placenta disorders including infiltration of intestinal organs have to be considered even after minor surgical interventions such as myomectomy. Second, clinical presentation is extremely variable and sometimes misleading, depending on the localization and the type of invasion. Our case underlines the importance of histopathologic work-up for distinguishing between various placenta attachment disorders such as PP and scar pregnancy. Given the large overlap in clinical presentation, pathophysiology and definition, we propose that the current definitions for PP and scar pregnancy have to be carefully reevaluated and broadened.
Patients with adrenal insufficiency (AI) irrespective of being on glucocorticoid replacement therapy still suffer from increased morbidity and mortality. GSK503 cost A major contributing factor is an inability of conventional glucocorticoid treatment to mirror the physiological cortisol rhythm. Novel strategies to replicate the cortisol rhythm using hydrocortisone infusion pumps and oral modified release hydrocortisone have now been developed and confirmed to offer benefits to patients.
In the DREAM study, when compared to multiple daily dosing of glucocorticoids Plenadren reduced weight, was less immunosuppressive and resulted in a better quality of life besides reducing infections. Chronocort that provides the early morning rise in cortisol improves androgen concentrations compared to conventional glucocorticoid treatments in congenital adrenal hyperplasia (CAH). Physiological hydrocortisone infusion pumps improve cortisol profiles with better adrenocorticotrophic hormone, glucose control, and quality of life (QOL) with androgen levels better controlled in CAH.
Advances in glucocorticoid replacement for patients with AI are ongoing. Novel approaches to managing AI, enabled by this armamentarium of drug formulations, aims to improve patient health. Currently, their use should be reserved for patients with metabolic complications, very poor QOL and difficult-to-treat CAH. Larger studies based on outcomes are essential to understand to what extent these strategies can replace conventional treatments.

The cystic lymph node (CLN) represents an anatomic safety marker and a surrogate marker of technique during laparoscopic cholecystectomy (LC). We aim to demonstrate the value of CLN in comparison to the critical view of safety (CVS) and study the effects of increasing difficulty on the 2 approaches.
A prospective study of consecutive LC was conducted. Patient demographics, type of admission, clinical presentation, operative difficulty grade, visualization of CLN, identification of CVS, operative time, and complications were recorded and analyzed.
Of 393 LCs, half of the admissions were emergencies. Thirty-four percent had obstructive jaundice or acute cholecystitis. The CLN was visually identified in 81.7% with a small difference between operative difficulty grades 1 to 3 versus 4 to 5. Although CVS was unachievable in 62 patients, 43 (69.4%) still had an identifiable CLN. The median operating time was 68 minutes with 1 mortality but no conversions or intraoperative complications.
Identifying the CLN during LC could compliment the CVS in avoiding major ductal injury.
