Ovarian endometriomas affect 17 to 44% of women with endometriosis, and are often associated with pelvic pain and infertility. Treatment options include expectant management, medical and/or surgical treatment, and in vitro fertilization and embryo transfer (IVF-ET). The choice of treatment depends mostly on the associated symptoms. In most cases, surgery is the preferred choice, since endometriomas do not respond to medical treatment, which may only treat associated pain. In case of infertility, IVF-ET may be a suitable alternative to surgery, particularly when there is no associated pain...

Numerous synergistic cancer immunotherapy combinations have been identified, but the effects of relative dose timing are rarely considered. In established syngeneic mouse tumor models, we found that staggering interferon-α (IFNα) administration after, rather than before or simultaneously with, serum-persistent interleukin-2 (IL-2) and tumor-specific antibody significantly increased long-term survival. Successful combination therapy required IFNα-induced activation of cross-presenting CD8α(+) dendritic cells (DCs) following the release of antigenic tumor debris by the IL-2- and antibody-mediated immune response...

Radioembolization (RE) is a relatively novel treatment modality for primary and secondary hepatic malignancies. Microspheres embedded with a β-emitting radioisotope are injected into the hepatic artery, resulting in microsphere deposition in the tumor arterioles and normal portal triads. Microsphere deposition in nontumorous parenchyma can result in radiation-induced liver injury, with lethal RE-induced liver disease (REILD) at the outer end of the spectrum. The primary aim of this study was to evaluate RE-related hepatotoxicity and present an overview of the currently applied definitions and clinically relevant characteristics of REILD...

Inflammatory breast cancer (IBC) is a rare and aggressive form of breast cancer, which accounts for approximately 3% of cases of breast malignancies. Diagnosis relies largely on its clinical presentation, and despite a characteristic phenotype, underlying molecular mechanisms are poorly understood. Unique clinical presentation indicates that IBC is a distinct clinical and biological entity when compared to non-IBC. Biological understanding of non-IBC has been extrapolated into IBC and targeted therapies for HER2 positive (HER2+) and hormonal receptor positive non-IBC led to improved patient outcomes in the recent years...

BACKGROUND: Merkel cell carcinoma (MCC) is an aggressive skin cancer with a recurrence rate of >40%. Of the 2000 MCC cases per year in the United States, most are caused by the Merkel cell polyomavirus (MCPyV). Antibodies to MCPyV oncoprotein (T-antigens) have been correlated with MCC tumor burden. The present study assesses the clinical utility of MCPyV-oncoprotein antibody titers for MCC prognostication and surveillance. METHODS: MCPyV-oncoprotein antibody detection was optimized in a clinical laboratory...

OBJECTIVES: Intrathyroid metastases from extrathyroid primary tumors are rare. Clinical findings may be subtle, but detection of intrathyroid metastases has improved with sonography. The objective of this study was to evaluate the sonographic appearance of intrathyroid metastases. METHODS: Patients with thyroid masses with cytopathologic features matching those of an extrathyroid primary tumor were retrospectively identified. The appearances of intrathyroid metastases on sonography were reviewed for the following features: size, margin regularity, echogenicity, echotexture, vascularity on power or color Doppler ultrasonography, and the presence or absence of any associated cervical adenopathy...

Metaplastic tumors are rare and represent a heterogeneous group of neoplasms showing dominant areas of non-glandular differentiation. Etiology and pathogenesis of this type of lesion in the breast is uncertain. The most common sources of metastatic squamous cell carcinoma of the breast are lung, esophagus, cervix, and urinary bladder. Squamous cell carcinomas may present clinically with inflammation and average size greater than breast adenocarcinoma. As for imaging studies, mammography shows no typical findings and ultrasound can show a complicated cyst or an inflammatory process, among the differential diagnoses...

Indoor allergens are among the main causes of allergic rhinitis and asthma. Allergen exposure is not limited to private homes. Mite, cat, and dog allergens were measured in day care centers to determine whether these concentrations detected might exert significant influence on human health. In 20 day care centers across North Rhine-Westphalia, Germany, the surfaces of 171 rooms were vacuumed 4 times a year to collect dust (1340 samples in total). In all samples, domestic mite antigens (DM) and the main allergens of cats (Fel d 1) and dogs (Can f 1) were quantified using enzyme immunoassays...

The influence of occupational risk factors on bladder cancer development is well investigated. However, studies on the influence on bladder cancer prognosis are rare. Therefore, it was of interest to investigate the time to first relapse in the follow-ups of three case-control series from Dortmund, Neuss, and Lutherstadt Wittenberg, Germany. Relapse-free survival of in total 794 urinary bladder cancer patients (Dortmund 174, Neuss 407, Lutherstadt Wittenberg 213) was derived from medical records. Cox regression models were used to determine the impact of profession and exposure to bladder carcinogens if the risk factor was present in at least four cases...

Tyrosinemia type II is a rare autosomal recessive disease caused by deficiency of hepatic tyrosine aminotransferase and is associated with neurologic and development difficulties in numerous patients. Considering that the mechanisms underlying the neurological dysfunction in hypertyrosinemic patients are poorly known and that high concentrations of tyrosine provoke mitochondrial dysfunction and oxidative stress, in the present study we investigated the in vivo influence of antioxidants (N-acetylcysteine, NAC; and deferoxamine, DFX) administration on the inhibitory effects on parameters of energy metabolism in cerebral cortex, hippocampus and striatum of rats, provoked by chronic administration of L...

BACKGROUND: Intra-neural arachnoid cyst is an extremely rare etiology of isolated cranial nerve palsy. Although seldom encountered in clinical practice, this pathology is amenable to surgical intervention. Correct identification and treatment of the cyst are required to prevent permanent nerve damage and potentially reverse the deficits. We describe a rare case of isolated third nerve palsy caused by an intra-neural arachnoid cyst. CASE DESCRIPTION: A 49 year old female with recent history of headaches presented with acute onset of painless left-sided 3rd nerve palsy...

BACKGROUND: Ogilvie's syndrome (OS) is a relatively uncommon pathology characterized by significant colonic dilation in the absence of mechanical obstruction. If unrecognized and untreated, cecal perforation resulting in mortality rate of 25-71% may occur. It is a potentially underdiagnosed condition in the lateral transpsoas appraoch population due to its uncommon nature and imitation of other well-known pathologies. METHODS: A total of 2930 patients from 6 separate institutions were retrospectively reviewed since 2007 and screened for OS...

BACKGROUND: Brainstem intramedullary schwannomas (ISs) are extremely rare. Various theories have been suggested to explain its origin. Mason and Keigher first speculated that IS arises from the region where the nerve roots lose their sheaths on penetrating the pia mater. Wood et al. further predicted that IS will contain both intra- and extramedullary part and shape like a "dumbbell". However, no cases reported previously can support this assumption adequately. CASE DESCRIPTION: A 40-year-old woman presented with constant cervical pain, accompanied by progressive weakness of upper extremities and glove distribution numbness...

Central nervous system mucormycosis is an aggressive fungal infection often ending in fatality. The usual circumstance is an immunocompromised individual presenting with rapidly progressive rhinocerebral involvement. An extremely rare variant of central nervous system mucormycosis isolated to the basal ganglia in an immunocompetent intravenous drug user is detailed in this manuscript. The patient was aggressively treated with aspiration of the fungal abscess and long-term intravenous antifungal agents.

Pegylated liposomal doxorubicin (PLD) has been approved to treat patients with various types of cancers because it rarely caused side effects, such as cardiotoxicity, in comparison to doxorubicin, but it frequently results in hand-foot syndrome (HFS). This may affect the quality of life and require a reduction in the PLD dose. The pathophysiology of HFS was not well understood. This study was aimed at exploring the mechanism of HFS induced by PLD. We compared the effects of different doses of PLD on the proliferation inhibition and apoptosis in vitro in HaCaT cells and analyzed the skin changes and skin cell DNA damage in vivo using a zebrafish model...

Nasoethmoid schwannomas with significant intracranial extension are rare tumours that typically present with visual and olfactory deficits. We describe a nasoethmoid schwannoma in a patient who was completely asymptomatic. Despite impressive intracranial involvement, nasoethmoid schwannomas may present asymptomatically and should be considered in the differential of contrast-enhancing anterior skull base lesions.

Congenital absence of the pericardium (CAP) is a rare condition. Failure to recognize the clinical features of this condition can lead to incorrect and delayed diagnosis. Limited data are available regarding the optimal approach to diagnose and manage patients with suspected CAP. Due to the rare nature of CAP, this condition can present diagnostic and management dilemmas for clinicians. Using 3 cases of CAP as a framework, a clinically focused review on the diagnosis and management of CAP is presented. Clinicians will be provided with a systematic approach to evaluating patients with suspected CAP, incorporating key history, examination, and multimodality cardiovascular imaging investigations...
