Tip-Reduction Surgery: Bulbous Tip Correction and Long-Nose Correction

Plant stinging emergences exhibit functional similarities in that they all elicit a pain response upon contact. A stinging emergence consists of an elongated stinging cell and a multicellular pedestal (Fig. 1). A recent ultrastructural investigation of these structures has revealed the ontogeny and morphology of the stinging cells differs in representative genera in the four plant families which possess such structures. A unique feature of the stinging cell of Urtica dioica is the presence of a siliceous cell wall in the apical portion of the cell. This rigid region of the cell wall is responsible for producing the needle-like apparatus which penetrates the skin. The stinging cell differentiates the apical bulbous tip early in development and the cell continues growth by intercalary addition of non-silicified wall material until maturity.The uppermost region of the stinging cell wall is entirely composed of silica (Fig. 2, 3) and upon etching with a 3% solution of HF (5 seconds), the silica is partially removed revealing the wall consisting of individualized silica bodies (Fig. 4, 5).

Background: Large frontoencephaloceles, more common in low and middle-income countries, require complex reconstruction of cerebral herniation, elongated nose, telecanthus, and cephalic frontal bone rotation. Previously described techniques involve multiple osteotomies, often fail to address cephalad brow rotation, and have high complication rates including up to 35% mortality. This study presents a novel, modified, single-staged technique for frontoencephalocele reconstruction performed by Mercy Ships. This technique, which addresses functional and aesthetic concerns with minimal osteotomies, may help improve outcomes in low resources settings. Methods: Retrospective review was performed of patients who underwent frontoencephalocele reconstruction through Mercy Ships using the technique described. Patient data including country, age, gender, associated diagnoses, and prior interventions were reviewed. Intraoperative and post-operative complications were recorded. Results: Eight patients with frontoencephalocele (ages 4-14 years) underwent surgery with the novel technique in 4 countries. Average surgical time was 6.0 ± 0.9 hours. No intraoperative complications occurred. Post-operatively 1 patient experienced lumbar drain dislodgement requiring replacement and a second had early post-operative fall requiring reoperation for hardware replacement. In person follow-up to 2.4 months showed no additional complications. Follow-up via phone at 1 to 2 years post-op revealed all patients who be satisfied with surgical outcomes. Conclusions: Reconstruction of large frontoencephaloceles can be challenging due to the need for functional closure of the defect and craniofacial reconstruction to correct medial hypertelorism, long nose deformity, and cephalad forehead rotation. The novel surgical technique presented in this paper allows for reliable reconstruction of functional and aesthetic needs with simplified incision design, osteotomies, and bandeau manipulation.

By taking advantage of a modified osmium maceration technique, we have been able to examine by high resolution scanning electron microscopy (HRSEM) the interior of human adrenocortical mitochondria from which all soluble material has been extracted. The so-called vesicles apparent in thin sections examined by transmission electron microscopy actually are finger-like cristae as determined by HRSEM. These digitiform cristae have a segmented appearance and a bulbous tip. The segmented form of the cristae may have important metabolic implications.

A 22-year-old male presented to outpatient department with the complaint of widened nasal tip. He was a known case of rhinoscleroma diagnosed five years ago and had taken treatment for the same for one year. He has been asymptomatic since then. On clinical examination the patient had widening of the dorsum of the nose with a bulbous nasal tip. Anterior rhinoscopy was within normal limits. Rhinoplasty was done and the patient had an improvement in his cosmetic appearance. This is one of unique cases of rhinoplasty on bulbous tip due to rhinoscleroma.

The present work provides a detailed account of a pneumatic measuring technique appropriate for flow field measurements in turbomachinery configurations, making use of long-nose 5-hole probes. The way of obtaining flow quantities in a frame of reference on the sensing head of the probe is first addressed. Transformation of velocity co-ordinates from the probe frame to a stationary frame, customary for turbomachinery flows, is then discussed. Sources of error are also discussed, with particular attention on those that can be introduced by the nose geometry and the co-ordinate transformations. The potential of the measuring technique is demonstrated by presenting the application of the technique for measurements in an annular cascade facility. The results are compared to results obtained by a 3-D Laser-Doppler Anemometer.

Train Simulation ◽

Cross-wind flows around two simplified high-speed trains with different nose shapes are studied using large-eddy simulation (LES) with the standard Smagorinsky model. The Reynolds number is 3×105 based on the height of the train and the freestream velocity. The cross section and the length of the two train models are identical while one model has a nose length twice that of the other. The three-dimensional effects of the nose on the flow structures in the wake and on the aerodynamic quantities such as lift and side force coefficients, flow patterns, local pressure coefficient, and wake frequencies are investigated. The short-nose train simulation shows highly unsteady and three-dimensional flow around the nose yielding more vortex structures in the wake. These structures result in a surface flow that differs from that in the long-nose train flow. They also influence the dominating frequencies that arise due to the shear-layer instabilities. Prediction of vortex shedding, flow patterns in the train surface, and time-averaged pressure distribution obtained from the long-nose train simulation are in good agreement with the available experimental data.

AbstractOpposing facial features between animated villains and heroes have historically been used to demonstrate contrasting morality between characters, and this could have an impact on how humans view someone as good or evil in everyday life. Studies have been done investigating classic dermatologic features of villainous characters. This principle can be applied to nasal features as well. A search for “top animated characters” was performed. Characters were chosen from American Film Institute's “The Top Tens,” Rolling Stone's “25 Best Pixar Movie Characters,” and Screenrant's “The 30 Best Animated Movie Characters of All Time.” Twenty villains and twenty hero counterparts from respective films were chosen. Classic nasal features were analyzed. Twenty villains (14 male, 6 female) and 20 heroes (12 male, 8 female) were analyzed. Sixteen villains (80%) had greater than normal nasal frontal angle versus 18 heroes (90%). Thirteen villains (65%) had an acute nasolabial angle versus two heroes (10%). Two villains (10%) had excess columellar show versus seven heroes (35%). Seven villains (35%) and one hero (5%) had a dorsal hump. Twelve villains (60%) had an overprojected chin versus three heroes (15%). Villains in pre-2000s films more frequently had a dorsal hump, overprojected chin, ptotic tip, pollybeak deformity, and bulbous tip. Heroes in pre-2000s films more frequently had an overrotated tip. Villains and heroes commonly have a greater than normal nasofrontal angle. Villains more commonly have an acute nasolabial angle, underrotated tip, overprojected chin, dorsal hump, and pollybeak deformity. Heroes more commonly have a large nasolabial angle and overrotated tip. Further research in conjunction with psychologists is required to obtain concrete data on how this affects whether an individual in real life is seen as good or evil, and the impact this has on interactions in society, including in the medical field.
