Coronary cameral fistula is a rare congenital cardiac abnormality. An 18-year-old boy presented with features of right heart volume overload. Clinical examination was suggestive of hyperdynamic circulation with continuous murmur in precordium. 2D echocardiography showed dilated right coronary artery, and 3D echocardiography added information in tracing the track of the fistula which was consistent with the diagnosis of right coronary cameral fistula draining into the right ventricle. Coronary angiograms revealed an unusually dilated right coronary artery giving the appearance of an "elephant trunk" and with a fistulous tract into the right ventricle...

The large estuaries can present long narrow branches called subestuaries or tidal creeks. These types of subsystems are distributed along the Uruguayan coast of the Río de la Plata estuary and are very important as nursery and refuge areas for fish. For the first time, the seasonal composition and abundance of the fish community of the Solís Chico subestuary was studied by using beach and gill nets. Fourteen species, mainly euryhaline (86%) presented a significant representation of juvenile stages. The fish community was dominated by Odontesthes argentinensis, Platanichthys platana, Mugil liza, Brevoortia aurea, Micropogonias furnieri and Paralichthys orbignyanus, similar to adjacent subestuaries...

The increased incidence of stress urinary incontinence (SUI) in postmenopausal women has been proposed to be associated with a reduction in the level of 17-β estradiol (E2). E2 has also been shown to enhance the multi-differentiation ability of adipose-derived stem cells (ASCs) in vitro. However, studies on the potential value of E2 for tissue engineering in SUI treatment are rare. In the present study, we successfully fabricated myogenically differentiated ASCs (MD-ASCs), which were seeded onto a Poly(l-lactide)/Poly(e-caprolactone) electrospinning nano-scaffold, and incorporated E2 into the system, with the aim of improving the proliferation and myogenic differentiation of ASCs...

Whale sharks are generally associated with environmental factors that drive their movements to specific locations where food availability is high. Consequently, foraging is believed to be the main reason for the formation of whale shark aggregations. Feeding aggregations occur mainly in nearshore areas and are composed primarily of immature individuals. Conversely, aggregations of mature adults are rarely observed, and their occurrence is correlated with oceanic environments. Despite an increase in the number of whale shark studies, information on mating and parturition grounds is still lacking...

The controllable isotropic thermal expansion with a broad coefficient of thermal expansion (CTE) window is intriguing but remains challenge. Herein we report a cubic MZrF6 series (M = Ca, Mn, Fe, Co, Ni and Zn), which exhibit controllable thermal expansion over a wide temperature range and with a broader CTE window (-6.69 to +18.23×10-6/K). In particular, an isotropic zero thermal expansion (ZTE) is achieved in ZnZrF6, which is one of the rarely documented high-temperature isotropic ZTE compounds. By utilizing temperature-dependent high-energy synchrotron X-ray total scattering diffraction, it is found that the flexibility of metal∙∙∙F atomic linkages in MZrF6 plays a critical role in distinct thermal expansions...

Hereditary leukonychia is a rare genetic nail disorder characterized by distinctive whitening of the nail plate of all twenty nails. Hereditary leukonychia may exist as an isolated feature, or in simultaneous occurrence with other cutaneous or systemic pathologies. Associations between hereditary leukonychia and mutations in the gene encoding phospholipase C delta-1 (PLCδ1) have previously been identified. However, the molecular mechanisms underlying PLCδ1-mutations and hereditary leukonychia remain uncharacterized...

A 3-month-old boy with primary congenital glaucoma developed a transient corneal endothelial opacity after needle bleb revision with adjunctive 5-fluorouracil. This case presents a rare toxicity that, although transient, is concerning due to the potential of amblyopia. The authors review prior cases of corneal opacity associated with 5-fluorouracil.

BACKGROUND: Conjoined twins are a rare medical phenomenon that offers a unique challenge for medical professionals. The complex anatomy of conjoined twins dictates their survival and amenability to separation, making each case different in terms of medical management, surgical planning, and patient outcomes. Thoraco-omphalo-ischiopagus twins, joined from the thorax to the pelvis, are one of the rarest orientations recorded in the medical literature, and successful separation of this subset of conjoined twins has not been documented...

Fe-based superconductors (FBS) present a large variety of compounds whose properties are affected to different extents by their crystal structures. Amongst them, the REFeAs(O,F) (RE1111, RE being a rare-earth element) is the family with the highest critical temperature Tc but also with a large anisotropy and Josephson vortices as demonstrated in the flux-flow regime in Sm1111 (Tc ∼ 55 K). Here we focus on the pinning properties of the lower-Tc Nd1111 in the flux-creep regime. We demonstrate that for H//c critical current density Jc at high temperatures is dominated by point-defect pinning centres, whereas at low temperatures surface pinning by planar defects parallel to the c-axis and vortex shearing prevail...

Non-traumatic wrist pain remains a diagnostic challenge. An accurate diagnosis is crucial in order to choose the appropriate treatment. We report the case of a 23-year-old female with a four-month history of mainly nocturnal wrist pain. There was no history of trauma or prior surgery. Radiographs and CT scans showed a lytic lesion with central nidus and sclerotic margins in the pisiform bone. Bone scan showed increased uptake in the pisiform bone. The diagnosis of osteoid osteoma was confirmed by histopathological analysis after complete surgical resection...

The diagnosis of nerve tumor(s) must be suspected in all cases of tumefaction or pain on the path of a nerve exacerbated by percussion. Solitary nerve tumors are primarily schwannomas, but other rare tumors may be present such as intraneural ganglion cysts of controversial origin. Preservation of nerve continuity is the underlying goal for any surgical procedure, irrespective of the type of tumor. Therapeutic outcomes are closely linked to tumor resectability; in most patients, the resectability of the tumor, its type and benignity can be predicted based on medical imaging...

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) results from NOTCH3 gene mutations, which lead to the degeneration of vascular smooth muscle cells (VSMCs). The clinical presentation of CADASIL patients is dependent on the impact of other vascular risk factors and the type of NOTCH3 mutation present. METHODS: Here, we report a rare pathogenic mutation on exon 14 of the NOTCH3 gene in a Chinese family affected by CADASIL with phenotypic peculiarities...

Metastatic involvement of gastrointestinal tract from breast cancer is a rare event. We report the case of a 61-year-old woman presenting with bowel obstruction, related to metastasis of a primary breast cancer she had 12 years earlier (a triple-negative invasive ductal carcinoma treated with surgery and chemotherapy). Bowel obstruction was caused by a 20-centimeter tumor in the jejunum, involving also the transverse colon. The patient underwent en bloc resection of tumor with jejunum and transverse bowel segment and received adjuvant chemotherapy with carboplatin and paclitaxel...

INTRODUCTION: Hemangioma is the most common benign tumor of the liver. Most cases are asymptomatic and do not require treatment. A hemangioma can rarely be pedunculated; as a result, it may undergo torsion and infarction, which can make it symptomatic. CASE PRESENTATION: We report the case of a 45-year-old woman with acute abdominal pain due to torsion of a giant pedunculated hepatic hemangioma around its vascular stalk. CONCLUSIONS: Pedunculated hemangioma of the liver is an uncommon benign tumor, a rare differential diagnosis for a mass located in the upper abdomen...
