Survival after neoadjuvant chemotherapy with or without bevacizumab or everolimus for HER2-negative primary breast cancer (GBG 44-GeparQuinto)†.

Background: The GeparQuinto study showed that adding bevacizumab to 24 weeks of anthracycline-taxane-based neoadjuvant chemotherapy increases pathological complete response (pCR) rates overall and specifically in patients with triple-negative breast cancer (TNBC). No difference in pCR rate was observed for adding everolimus to paclitaxel in nonearly responding patients. Here, we present disease-free (DFS) and overall survival (OS) analyses.

Unusual orange-colored choroidal metastases.

Purpose: To report the clinical and paraclinical features of two patients with orange- colored choroidal metastases in whom the primary cancers have not previously been associated with such lesions.

Case Report: Orange-colored choroidal lesions were detected on the fundus examination of one patient with metastatic small cell neuroendocrine tumor of the larynx and oropharynx, and in another subject with metastatic alveolar soft part sarcoma of the leg. Although ultrasonographic characteristics of the choroidal masses were comparable to those of choroidal hemangiomas, fluorescein angiography revealed delayed initial fluorescence along with minimal fluorescence in subsequent phases of the angiogram which were in clear distinction from the earlier appearing and progressively intense fluorescence observed with circumscribed choroidal hemangiomas.

Is iron oxide a tissue-specific contrast medium in diagnostic ultrasound? A case report.

We present a patient with Hodgkin's disease in whom computed tomography suggested focal lesions in the liver. As no lesions were detected by diagnostic ultrasound, magnetic resonance imaging (MRI) with iron oxide as contrast medium was performed for verification. MRI confirmed at least 3 small lesions.

[Cerebral air embolism after central venous catheter].

Introduction of air into the arterial circulation can cause cerebral air embolism, leading to severe neurological deficits. A case is reported on a patient suffering from fatal cerebral air embolism after a subclavian vein catheter had been inserted. The risks associated with inserting and removing central venous catheters are described.

Structure-function relationship of new anthralin derivatives assayed for growth inhibition and cytotoxicity in human keratinocyte cultures.

HaCaT keratinocyte cultures were exposed to twelve hydrophilic anthralin derivatives 1 to 12 with substituents at C-1 and C-8 of the anthrone skeleton, of one H at C-10 and of both H's at C-10 by lacton rings. After 3 microM treatment growth was determined by cellular protein content, 3H-thymidine- and 14C-amino-acid-uptake and cytotoxicity by the release of cytoplasmic LDH into the culture medium. In comparison to acetone control (100%) anthralin suppressed mean protein content, as well as DNA- and protein-synthesis to 33, 28, and 21%, respectively, and the drug revealed an enzyme release of 660%.

Anthralin derivatives--inhibition of 5-lipoxygenase--antipsoriatic efficacy.

Inhibition of 5-lipoxygenase by anthralin (1) and 41 derivatives is determined: the acids 38 and 39, the lactones 40-42 and 9-anthrone (8) are the most potent inhibitors, the lactone 41 reaching the efficacy of nordihydroguaiaretic acid (NDGA). The results were correlated with the hydrophilic/lipophilic balance of the test compounds and their clinical efficacy as far as known. There is no correlation between the "minimum structure" of Krebs and Schaltegger concerning antipsoriatic activity and the inhibitory effects against 5-lipoxygenase.

Adenoma of the nonpigmented epithelium of the ciliary body.

A 56-year-old man presented with a left ciliary body mass, anterior vitreous hemorrhage and a subluxed, cataractous lens. The clinical course included rapid enlargement of the mass, anterior uveitis, cataract progression and secondary glaucoma. Investigation included fluorescein angiography, ultrasonography and computed tomography.

Nanophthalmos in sisters, one with exfoliation syndrome.

In a consanguineous family of two siblings, both with nanophthalmos, one was found to also have bilateral exfoliation syndrome. This combination of conditions has not, to our knowledge, previously been reported and has not had any apparent negative consequences. Her sister has manifested typical complications of nanophthalmos, including angle-closure glaucoma initially and, eventually, severe uveal effusion after cataract surgery.

Computed tomography of choroidal melanoma and scleral buckle.

In the investigation of a patient with choroidal melanoma in one eye and repaired rhegmatogenous retinal detachment in the other, a C.T. scan demonstrated the tumour in the right globe and the encircling silastic sponge around the left globe.
