Endometrial human chorionic gonadotropin (hCG) expression is a marker for adequate secretory transformation of the endometrium.

PURPOSE: Successful embryo implantation into the endometrium depends on embryonic characteristics and proper endometrial development. Reproductive medicine often focuses on embryo quality, whereas reliable diagnostic tests for endometrial receptivity are still needed. We previously found that human chorionic gonadotropin (hCG), one of the earliest proteins secreted by the embryo, was also expressed by the luteal phase endometrium around the implantation window. Here, we tested our hypothesis of endometrial hCG as an implantation marker. METHODS: Endometrial biopsies and serum samples were taken from patients undergoing routine infertility diagnostics. Correlations of immunohistochemically detected endometrial hCG expression with adequate endometrial secretory transformation, the infiltration of CD45-positive leukocytes, clinical diagnostic parameters, and endometrial thickness were analyzed. RESULTS: A highly significant correlation between the endometrial score, as a measurement for regular secretory transformation, and the intensity of hCG staining was found. The invasion of CD45-positive leukocytes increased with progressing endometrial secretory transformation and rising endometrial hCG expression. In addition, serum progesterone concentrations correlated with hCG expression by the endometrial glands. CONCLUSIONS: Our results suggest endometrial hCG as a possible diagnostic parameter characterizing the endometrial secretory transformation and, thus, possibly also its implantation capability.

Severe atypical herpes zoster as an initial symptom of fatal myelodysplastic syndrome with refractory anemia and blast excess (RAEB II).

Herpes zoster is a common disease caused due to varicella zoster virus (VZV) infection with increasing incidence by age. If the patient has a severe, extended, or treatment-recalcitrant course of herpes zoster, this must be a red flag to search for underlying pathologies. Here, we report about a 64-year-old male patient with diabetes, who came to our emergency department because of general malaise, fever, chills, and a pronounced nuchal and facial swelling on the left side. Based on herpetiform-grouped vesicles and yellowish crusts, an impetiginized facial herpes zoster was diagnosed, and combined antiviral and antibiotic treatment was initiated. He was HIV negative. Despite intensified treatment, his situation worsened. We observed blasts in peripheral blood, but bone marrow biopsy was initially denied. Some days later after deterioration of his disease, he accepted further diagnostics. A myelodysplastic syndrome with blast excess (refractory anemia and blast excess II, RAEB II) could be confirmed. The following translocations were detected: t(2;12)(p13; q13) and t(6;9)(p22;q34). REAB II has an unfortunate prognosis. Cytoreductive treatment was initiated by the hematooncologist. Unfortunately, the patient deceased due to septic shock.

Multisystemic Sarcoidosis Presenting as Pretibial Leg Ulcers.

Sarcoidosis is a multisystemic disease of unknown etiology. Up to 30% of patients develop cutaneous manifestations, either specific or nonspecific. Ulcerating sarcoidosis leading to leg ulcers is a rare observation that may lead to confusions with other, more common types of chronic leg ulcers. We report the case of a 45-year-old female patient with chronic multisystemic sarcoidosis presenting with pretibial leg ulcers. Other etiology could be excluded. Histology revealed nonspecific findings. Therefore, the diagnosis of nonspecific leg ulcers in sarcoidosis was confirmed. Treatment consisted of oral prednisolone and good ulcer care. Complete healing was achieved within 6 months. Sarcoidosis is a rare cause of leg ulcers and usually sarcoid granulomas can be found. Our patient illustrates that even in the absence of sarcoid granulomas, leg ulcers can be due to sarcoidosis.
