ABSTRACT Double-chambered right ventricles (DCRV) and left ventricles are rare entities on their own. We present two cases with an unusual combination of double-chambered right as well as left ventricles. One was discovered in a 28-year-old female, while the other was found at birth in a female child. The differing nature of both the patient demographics as well as the presentation with a common morphological background is shown on both computed tomography and magnetic resonance imaging. The oldest description of an obstructive muscular band within the right ventricle was given in 1867. In the literature, there is ample description of the long-term prognosis and management guidelines for DCRV, but no inheritance patterns or risk factors have been identified except for associations with septal defects, tetralogy of Fallot and transposition of the great arteries. A combination of both double-sided left as well as right ventricles has been published in literature a few times with little details about management and prognosis. SIMILAR CASES PUBLISHED: Although many cases of DCRV and DCLV have been published, to our knowledge only 3 cases of combined DCRV and DCLV have been published in literature.

✓ Except for villous hypertrophy of the choroid plexus that may not be true tumors, multiple choroid plexus papillomas are extremely rare. The authors report a case involving multiple choroid plexus papillomas that were distinct from villous hypertrophy. These lesions were localized, one in the atrium of the right lateral ventricle and the other in the inferior horn of the left lateral ventricle. A review of the literature revealed that this case represented the first reported case of true multiple choroid plexus papillomas documented by findings on magnetic resonance imaging.

Abstract Reservoir simulation is a mature technology, and nearly all major reservoir development decisions are based in some way on simulation results. Despite this maturity, the technology is changing rapidly. It is important for both providers and users of reservoir simulation software to understand where this change is leading. This paper takes a long-term view of reservoir simulation, describing where it has been and where it is now. It closes with a prediction of what the reservoir simulation state of the art will be in 2007 and speculation regarding certain aspects of simulation in 2017. Introduction Today, input from reservoir simulation is used in nearly all major reservoir development decisions. This has come about in part through technology improvements that make it easier to simulate reservoirs on one hand and possible to simulate them more realistically on the other; however, although reservoir simulation has come a long way from its beginnings in the 1950's, substantial further improvement is needed, and this is stimulating continual change in how simulation is performed. Given that this change is occurring, both developers and users of simulation have an interest in understanding where it is leading. Obviously, developers of new simulation capabilities need this understanding in order to keep their products relevant and competitive. However, people that use simulation also need this understanding; how else can they be confident that the organizations that provide their simulators are keeping up with advancing technology and moving in the right direction? In order to understand where we are going, it is helpful to know where we have been. Thus, this paper begins with a discussion of historical developments in reservoir simulation. Then it briefly describes the current state of the art in terms of how simulation is performed today. Finally, it closes with some general predictions.

The Relationship

Background Intracranial tuberculosis (TB) is an intracranial infection caused by Mycobacterium tuberculosis. Magnetic resonance imaging (MRI), in particular enhanced MRI scan, has the ability to detect characteristic lesions of tuberculous meningitis or cerebral parenchymal TB. Purpose To analyze the relationship between MRI findings and prognosis of patients with intracranial TB. Material and Methods In this retrospective study, a total of 60 patients were confirmed with intracranial TB in the hospital from May 2019 to December 2020. All enrolled patients underwent TB-related laboratory examinations, cranial MRI, and contrast-enhanced MRI. Laboratory tests were analyzed and the relationship between clinical prognosis and cranial MRI features was evaluated. Results Of the 60 patients, 28 (46.67%) had disseminated TB complications, 20 (36.67%) had secondary TB complications, and the remaining 10 (16.66%) had lymphatic TB or spinal TB complications. Of the patients, 25 had good short-term prognosis and 35 had poor short-term prognosis; 44 patients had good long-term prognosis and 16 had poor long-term prognosis. The incidence of cerebral parenchymal tuberculomas on enhanced MRI was significantly higher in the group with good prognosis compared to that in the group with poor prognosis ( P < 0.05). Logistic analysis suggested that hydrocephalus (odds ratio [OR] = 0.057, 95% confidence interval [CI] = 0.003–0.444; P = 0.018) and cistern involvement (OR = 0.100, 95% CI = 0.011–0.581; P = 0.017) were independent risk factors for poor short-term prognosis. Conclusion MRI can display the pathological changes of intracranial TB in detail; hydrocephalus and cistern involvement were independent risk factors for poor short-term prognosis.

The article presents two clinical observations of the stay of metallic foreign bodies in the bronchi. In the first child, a needle pushpin with a plastic casing was for 2 years in the lumen of the lower lobe bronchus on the right, while in the other case the screw stayed also in the right lower lobe bronchus for two weeks. Removal of foreign bodies of bronchi is performed urgently after the appropriate preoperative preparation in the operating room. Removal of the foreign body was carried out with pronounced technical difficulties, after repeated attempts for an hour. There were no complications during and after manipulation. Bronchoscopy revealed narrowing of the lumen of the lower lobar bronchus, edema, and hyperemia of the mucous membrane, as well as granulation tissue, partially overlapping the clearance of the bronchus.

And Behavior

One spotted pike-characin Boulengerella maculata, managed in a public display aquarium for 7 yr, developed a small unilateral pink growth associated with the right nare. The growth eventually extended through both nares after 5 mo. B. maculata is a species of piscivorous fish that relies on visual acuity when hunting prey. The rapidly-growing bilateral tumor would have impeded vision if left untreated. The fish was managed for over 10 mo using only surgical debulking, topical liquid nitrogen, and occasional nonsteroidal anti-inflammatory medications as needed to reduce tumor size and restore sight. Diagnosis proved challenging due to superimposed inflammation, neoplasm cellular inconsistencies, and a lack of proven immunohistochemical stains or other diagnostic stains. Using tumor location and appearance, histopathology, advanced imaging, electron microscopy, special staining, and immunohistochemistry, the ultimate diagnosis confirmed olfactory neuroblastoma, or esthesioneuroblastoma. Although long-term prognosis is poor, hunting strategy of the affected species may dictate quality of life, as appetite, body condition, and behavior remained largely unchanged in this animal until time of euthanasia.
