Neuroendocrine tumours are uncommon or rare at all sites in the female genital tract. The 2014 World Health Organisation (WHO) Classification of neuroendocrine tumours of the endometrium, cervix, vagina and vulva has been updated with adoption of the terms low-grade neuroendocrine tumour and high-grade neuroendocrine carcinoma. In the endometrium and cervix, high-grade neoplasms are much more prevalent than low-grade and are more common in the cervix than the corpus. In the ovary, low-grade tumours are more common than high-grade carcinomas and the term carcinoid tumour is still used in WHO 2014...

BACKGROUND: Acute distal biceps tendon ruptures are uncommon injuries that often affect young active males, typically resulting from an eccentric load on their dominant extremity. The purpose of this study was to compare pullout strength and tendon gapping in the tension slide technique (TST) versus a knotless fixation technique (KFT). METHODS: Two sets of experiments were performed using cadaveric elbow specimens. In the first experiment, eight elbows from different cadavers were tested to compare TST with a standard locking whipstitch with KFT, four elbows in each group, using a standard locking whipstitch...

Statistics from structural genomics initiatives reveal that around 50-55% of the expressed, non-membrane proteins cannot be purified and therefore structurally characterized due to solubility problems, which emphasized protein solubility as one of the most serious concerns in structural biology projects. Lactobacillus plantarum CECT 748(T) produces an aggregation-prone glycosidase (LpBgl) that we crystallized previously. However, this result could not be reproduced due to protein instability and therefore further high-resolution structural analyses of LpBgl were impeded...

The use of mechanical circulatory support has become an increasingly common practice in patients with heart failure, whether used as bridge to transplantation or as destination therapy. The last couple of decades has seen a drastic change in the functioning of the left ventricular assist devices (LVAD), changing from the first generation devices running on pulsatile flow to the current continuous flow devices. Atrial and ventricular arrhythmias are common among heart failure patients, and though the systematic circulation is well supported in patients on mechanical circulatory support, these arrhythmias can still be the cause of detrimental symptoms and lead to potentially fatal outcomes...

INTRODUCTION: Primary small cell neuroendocrine carcinoma of the breast (SCNCB) is a very uncommon type of breast cancer. Histology and morphology are virtually indistinguishable from small cell neuroendocrine carcinomas of the lung (SCNCL), mandating a search for a primary site elsewhere in the body. There is no standard approach to treatment as there are only a limited number of cases reported in the literature. This report summarizes a case of primary SCNCB and presents a review of the literature...

Gelatinous zooplankton are a large component of the animal biomass in all marine environments, but are considered to be uncommon in the diet of most marine top predators. However, the diets of key predator groups like seabirds have conventionally been assessed from stomach content analyses, which cannot detect most gelatinous prey. As marine top predators are used to identify changes in the overall species composition of marine ecosystems, such biases in dietary assessment may impact our detection of important ecosystem regime shifts...

INTRODUCTION: Pituitary tuberculosis is an uncommon cause of sellar mass [1]; the estimated prevalence worldwide is not known, and there have been no reports of the condition occurring in Ireland. Tuberculosis of the pituitary gland may present as a sellar mass or with symptoms of hypopituitarism. CASE PRESENTATION: A 41-year-old woman, with a short prodromal history without endocrine symptoms, was found to have pituitary tuberculosis after the demonstration of a sellar mass on MRI, and lumbar puncture findings consistent with lymphocytic meningitis...

BACKGROUND: Long-term feeding by percutaneous endoscopic gastrostomy tube (PEG) is uncommon but can present significant issues when both nutrition and medication have to be fed down the same tube. This is especially important in people with epilepsy where the dose and bioavailability of antiepileptic drugs are critical to maintain adequate seizure control. This group with long-term PEG tubes is particularly vulnerable and dependent on their carers to provide high standard of care. Indeed, approximately half of the people with long-term feeding tubes suffer from severe intellectual disability which requires careful coordination of all members of the multidisciplinary team...

Biliary ileusis a uncommon cause of mechanical bowel obstruction, affecting older adult patients who often have other significant medical conditions. It is caused by intestinal impaction of a gallstone that enters the bowel via a cholecysto-enteric fistula. The mortality rate is considerable, ranging between 12 and 27%. Treatment in most cases is surgical, aimed at the resolution of the intestinal obstruction. We report the case of a 55 year old patient diagnosed with biliary ileus, wich evolved without complications after a enterolithotomy...

Atypical rhabdoid/teratoid tumor (ATRT) is an uncommon and highly malignant tumor of the central nervous system. The majority of ATRT tumors occur in infancy and young children located in the posterior fossa. The ideal treatment for cure remains controversial and prognosis is typically unfavorable. We present a case of an atypical presentation of ATRT, presenting in adolescence with an additional low-grade glioneuronal tumor discovered at diagnosis.

Nummular eczema or dermatitis is an uncommon paediatric pathology. It is presented as red-purplish small papules and vesicles that join to form exudative circular patches and then to eczematous or lichenified patches with discoid shape. The lesions appear predominantly on the extensor surface of extremities, although they can appear in trunk, hands or feet. This pathology has a clinical diagnosis; only few cases require complementary test. The topical corticosteroids are the mainstay of the treatment, and the causal treatment whether an infectious trigger is found...

OBJECTIVE Multiple meningiomas account for 1%-10% of meningiomas. This study describes epidemiological aspects of the disease and its management, which is more challenging than for single tumors. METHODS A consecutive series of adult patients with ≥ 2 spatially separated meningiomas was reviewed. Patients with neurofibromatosis Type 2 were excluded. The authors collected clinical, imaging, histological, and treatment data to obtain information on epidemiology, management options, and outcomes of active treatment and surveillance...

Solitary fibrous tumors are an uncommon sarcoma type characterized by NAB2-STAT6 gene fusion. While solitary fibrous tumors metastasize in 5-25% of cases, it has historically been challenging to determine which specific tumor and patient characteristics predict aggressive behavior. We previously reported on a novel risk stratification scheme for solitary fibrous tumors incorporating patient age, tumor size, and mitotic activity to predict risk of metastasis. Herein we validate this risk stratification scheme in an independent, lower-risk population of 79 patients with primary non-meningeal solitary fibrous tumors, and propose incorporating tumor necrosis as a fourth variable to further improve the risk score...

Bartonella quintana endocarditis, a common cause of culture-negative endocarditis in adults, has rarely been reported in children. We describe 5 patients 7-16 years of age from Ethiopia with heart defects and endocarditis; 4 cases were caused by infection with B. quintana and 1 by Bartonella of undetermined species. All 5 patients were afebrile and oligosymptomatic, although 3 had heart failure. C-reactive protein was normal or slightly elevated, and erythrocyte sedimentation rate was high. The diagnosis was confirmed by echocardiographic demonstration of vegetations, the presence of high Bartonella IgG titers, and identification of B...

Anaerobic bone and joint infections are uncommon, although the number of anaerobic infections is presumably underestimated because of difficulties with isolation and identification of obligate anaerobes. This study describes two cases of complicated Bacteroides fragilis peri-implant infection of the lumbar spine, infection of the hip and osteomyelitis. Bacteria were identified with the use of a mass spectrometer, VITEK MS system. Drug susceptibility was performed with the use of E-test. The EUCAST breakpoints were used for interpretation with B...

We describe an additional case of spastic paretic hemifacial contracture, an uncommon condition characterized by sustained unilateral contraction of the facial muscles associated with mild ipsilateral facial paresis. This entity has only rarely been associated with multiple sclerosis (MS) and can be mistaken for hemifacial spasm. Early consideration of MS in the differential diagnosis of young patients admitted with these symptoms is essential.

Cryptosporidiosis is a relatively uncommon disease in healthy individuals but could be potentially worrisome in immunocompromised patients. This study aimed to evaluate Cryptosporidium infection in children with cancer undergoing chemotherapy. A case-control study was conducted in 132 children with cancer undergoing chemotherapy and 132 non-cancer controls. The modified Ziehl-Neelsen (MZN) staining and polymerase chain reaction methods were used for the detection of Cryptosporidium parasite. All positive isolates were sequenced for phylogenetic analysis...
