The literature regarding size descriptions for spermatic cord lipomas is limited. The term "giant" is utilized loosely and seen on case reports for masses as small as 6cm. Here we present a case of a giant left sided spermatic cord lipoma, found incidentally during a recurrent inguinal hernia repair, that measured 18×14×10 cm on final pathologic examination.
A 59year old male, with a history of morbid obesity and surgical history of prior bilateral inguinal hernia repair, presented with recurrent left sided groin and scrotal bulging with associated discomfort several months after the initial hernia repair. Following imaging performed on preoperative work up, the patient was brought to the operating room for a robotic inguinal hernia repair.
Preoperative physical examination was limited due to the patient's body habitus which precluded a definitive diagnosis of inguinal hernia based on physical examination. Computed tomography of the abdomen and pelvis was performed with findings consistent with bilateral recurrent inguinal hernias. A bilateral robotic inguinal hernia repair was attempted. find more The procedure was converted to open via a groin incision when an incidental 18cm left sided spermatic cord lipoma was discovered. An orchiectomy was ultimately performed as the mass was intimately intertwined with the spermatic cord.
In our case, the patient had a recurrent inguinal hernia and an incidental finding of an 18cm spermatic cord lipoma which warranted a left orchiectomy followed by open inguinal hernia repair. We propose standardizing the term "giant" to include spermatic cord lipomas >15cm.
15 cm.Chlorinated paraffins (CPs) are high production volume plasticizers and flame retardants, which have exhibited bioaccumulative and toxic properties. CPs may be released from treated consumer goods and bind with indoor dust, leading to human exposure via unintentional dust ingestion. In this study, the concentrations and homologue distribution of CPs were measured in 50 indoor dust samples collected in paired winter and summer sampling campaigns from 25 homes in Flanders, Belgium. Short-, medium- and long-chain CPs (SCCPs (C10-13), MCCPs (C14-17) and LCCPs (C18-20), respectively) were each detected in all Belgian indoor dust samples with overall median concentrations of 6.1 µg/g (range 0.61 to 120 µg/g), 45 µg/g (range 4.5 to 520 µg/g) and 4.5 µg/g (range 0.3 to 50 µg/g), respectively. Concentrations were significantly higher in the winter samples than summer for each of the three groups (p less then 0.05). LCCPs homologues ranging from C21-32 were also detected in dust samples and accounted for approximately half of the LCCP relative abundance based on instrumental peak area, although a lack of appropriate analytical standards prevented quantification of these homologues. While clear sources of CP contamination in dust could not be identified, significant associations between concentrations of ∑SCCPs, ∑MCCPs and ∑LCCPs (C18-20) (p less then 0.05) suggested the combined application within materials or products in homes. Based on typical exposure scenarios, estimated daily intake of ∑CPs (C10-20) for adults and toddlers were 14 and 270 ng/kg bw/day, respectively, though margin of exposure assessments for SCCPs and MCCPs indicated that adverse health effects were unlikely for all exposure scenarios. This study presents the first evidence of seasonal variation in the levels and distribution for each of the SCCP, MCCP and LCCP classes in indoor dust and highlights the urgent need for appropriate analytical standards for LCCP quantification.The aim of this study was to investigate whether parameters obtained by computer-assisted sperm analysis (CASA), infrared thermography (IRT), and testicular B-mode and Doppler ultrasound can be used as indicators of fertility in natural service Nellore bulls. Twenty-nine Nellore bulls were evaluated on days 66 (-D66), 38 (-D38), and 10 (-D10) before the beginning of natural service mating. In all assessments, semen samples were collected and sperm kinetics were evaluated by CASA, thermographic imaging of the scrotal and ocular region, testicular B-mode ultrasound, and Doppler ultrasound of the spermatic cord. At the end of natural service, the bulls were classified based on the pregnancy rate of individual batches into low fertility (pregnancy rate 66.57 ± 0.62 %), medium fertility (76.47 ± 0.51 %), and high fertility (84.80 ± 0.60 %) groups. No difference in the IRT parameters was observed between groups. High fertility animals exhibited higher average path velocity (VAP = 110.98 µm/s), straight line velocity (VSL = 87.05 µm/s), curvilinear velocity (VCL = 190.78 µm/s), pulsatility index (PI = 0.93), and resistive index (RI = 0.57) than low fertility animals (VAP = 100.02 µm/s; VSL = 79.84 µm/s; VCL = 173.22 µm/s; PI = 0.69; RI = 0.48). Positive correlations were observed between pregnancy rate and VSL (0.21), PI (0.28) and RI (0.32). In conclusion, IRT does not provide fertility indicators in Nellore bulls. The VAP, VSL and VCL obtained by CASA and PI and RI obtained by Doppler ultrasound can be used as indicators of fertility in Nellore bulls.A 51-year-old Japanese man presented with slowly progressing cerebellar ataxia from age 49. Anti-thyroglobulin, anti-thyroid peroxidase, and anti-NAE antibodies were detected. Brain magnetic resonance imaging showed moderate atrophy of the pons, cerebellum, and middle cerebellar peduncle. Dopamine transporter single-photon emission computed tomography showed normal uptake. With the diagnosis of Hashimoto's encephalopathy, repeated steroid pulse therapy and intravenous immunoglobulin therapy were administered; however, they were ineffective for cerebellar ataxia. Afterwards, autonomic failure and parkinsonism became evident. The final diagnosis was MSA of the cerebellar type. Immunotherapies for patients with MSA with anti-NAE antibodies should be carefully considered.While pure alexia was long considered a disconnection syndrome, it may also be a selective visual word agnosia due to damage to the visual word form area. Disconnection is still the likely explanation of hemi-alexias, though, particularly when splenial lesions damage inter-hemispheric projections and cause left hemi-alexia. An intra-hemispheric disconnection causing right hemi-alexia is theoretically possible but seems very rare, with only a single report that has been challenged on the grounds of inadequate perimetry. We describe the case of PH, who had a severe reading deficit in her right hemifield. Detailed perimetry showed only a small relative hemi-scotoma along the horizontal meridian, while word reading was impaired over a much larger expanse of her right hemifield, in which object recognition was spared. Reading, lexical decisions, and perceptual discrimination of words were impaired in the right hemifield, and this extended to letters and numbers, with a trend to an effect on the perception of an unfamiliar script, namely Korean. On magnetic resonance imaging she had a large left lateral occipital meningioma with vasogenic edema of occipital white matter tracts. Functional magnetic resonance imaging showed that the visual word form area was located just anterior to the mass. Her perceptual abnormalities resolved after resection of the tumor. We conclude that right hemi-alexia exists and is most likely due to intra-hemispheric disconnection of occipital input to the visual word form area.Allochiria refers to the mislocation of stimuli to the corresponding position on the opposite side of the body or hemispace. It is most often, although not exclusively, reported in the tactile modality and typically in association with unilateral neglect. We describe a patient presenting with a 2-year history of topographical disorientation without other cognitive complaints. We conducted a systematic exploration of his topographical problems to identify their cognitive substrate. Standard neuropsychological examination revealed no abnormalities. Notably, he performed well on perceptual, spatial, and constructional tasks. No signs of neglect were elicited. A tailored battery of tests was administered, involving road maps and landmarks, and designed to replicate the situations in which he experienced symptoms. The experimental tests showed no evidence of topographical agnosia or amnesia for landmarks and their spatial relationships and no hemispatial neglect. Nevertheless, the patient exhibited a systematic tendency to translocate topographical landmarks sited on the left to the right side. The phenomenon, consistent with representational allochiria, occurred exclusively for topographical landmarks, and was present along both personally familiar and new learned routes. Over the next two years more widespread visuoperceptual and spatial deficits emerged, with Balint and Gerstmann syndromes. Functional imaging revealed hypoperfusion of the occipito-parietal regions and amyloid PET the presence of amyloid plaques. A diagnosis was made of posterior cortical atrophy, the visual variant of Alzheimer's Disease. To our knowledge this is the first case of topographical disorientation presenting with selective representational allochiria and the first report of allochiria as an early sign of posterior cortical atrophy. The case sheds light on the cognitive basis of allochiria and on a puzzling clinical presentation of neurodegenerative brain disease.
Effective aggregation of intraoperative x-ray images that capture the patient anatomy from multiple view-angles has the potential to enable and improve automated image analysis that can be readily performed during surgery. We present multi-perspective region-based neural networks that leverage knowledge of the imaging geometry for automatic vertebrae labeling in Long-Film images - a novel tomographic imaging modality with an extended field-of-view for spine imaging.
A multi-perspective network architecture was designed to exploit small view-angle disparities produced by a multi-slot collimator and consolidate information from overlapping image regions. A second network incorporates large view-angle disparities to jointly perform labeling on images from multiple views (viz., AP and lateral). A recurrent module incorporates contextual information and enforce anatomical order for the detected vertebrae. The three modules are combined to form the multi-view multi-slot (MVMS) network for labeling vertebrae usie.g., bi-plane radiography). Predicted labels can help avoid adverse events during surgery (e.g., wrong-level surgery), establish correspondence with labels in preoperative modalities to facilitate image registration, and enable automated measurement of spinal alignment metrics for intraoperative assessment of spinal curvature.
Transverse sinus stenosis (TSS) is commonly found in Pulsatile Tinnitus (PT) patients. Vortex flow is prominent in venous sinus with stenosis, and so it is important to determine the distribution and strength of the vortical flow to understand its influence on the occurrence of PT.
In this study, by using computational fluid dynamics for hemodynamic analysis in patient-specific geometries based on Magnetic Resonance Imaging (MRI), we have investigated the blood flow within the venous sinus of 16 subjects with PT. We have employed both laminar and turbulent flow models for simulations, to obtain (i) streamlines of velocity distribution in the venous sinus, and (ii) pressure distributions of flow patterns in the venous sinus. Then, hemodynamic analysis in the venous sinus recirculation zone was carried out, to determine the flow patterns at the junction of transverse sinuses and sigmoid sinuses. Finally, we have proposed a new model for turbulence evaluation based on the regression analysis of anatomic and hemodynamics parameters.
