introduction clitromegaly can be congenital or acquired with the former type being more prevalent. the main etiology behind the acquired type is hormonal imbalance affecting mainly adult women. this type is seen mostly in association with polycystic ovarian syndrome, hyperthecosis, ovarian tumors, and clitoral cysts or it can be drug-induced. clitoral leiomyoma is a rare benign tumor of female ...

Objective: Nasal tip refinement is an important objective in aesthetic rhinoplasty and one of the surgical options for soft tissue management in very thick bulbous skin and subcutaneous noses is tip defatting. The aim of this study was to evaluate the safety and complications of tip defatting in thick skin and bulbous noses.     Methods: Among 527 patients that underwent rhinoplasty in Modar...

To test the role of constructional and dimensional factors in the generation of friction force by systems of setose attachment pads, six species of syrphid fly (Platycheirus angustatus, Sphaerophoria scripta, Episyrphus balteatus, Eristalis tenax, Myathropa florea and Volucella pellucens) were studied using light and scanning electron microscopy. Flies were selected according to their various b...

Urethral prolapse is a rare condition in dogs and cats. A 7-month-old male cat presented with intermittent penile bleeding and a red mass protruding from the tip of the penis. Urethral prolapse was diagnosed by using a surgical microcamera to examine the genital area. Urethroplasty and preputial advancement surgery were performed using a surgical microscope, to successfully correct the urethral...

INTRODUCTION The Thulium fiber laser has recently been tested as a potential alternative to the Holmium:YAG laser for lithotripsy. This study explores use of a short taper for expanding the Thulium fiber laser beam at the distal tip of a small-core fiber. METHODS Thulium fiber laser radiation with a wavelength of 1,908 nm, 10 Hz pulse rate, 70 mJ pulse energy, and 1-millisecond pulse duration...

An enhancing nodule was seen on T1-weighted enhanced scans at the tip of the caudally displaced cerebellar vermis in three patients with Chiari II malformation. The enhancing fibrovascular nodule found at the base of the cerebellum in patients with Chiari II malformation represents ectopic choroid plexus and should not be confused with a pathologic mass.

Experiments and simulations are used to elucidate a new class of chemical reactions occurring near the tip-sample interface during high field chemistry of diphenylgermane. Current data during writing and bias dependent growth rate are analyzed, supplemented with data from ionization mass spectrometry, and compared with the simulation results.

Two patients with giant basilar tip aneurysms underwent coil embolization, one with both platinum fiber and platinum Guglielmi detachable coils and the other with Guglielmi detachable coils only. In both cases, spontaneous intraaneurysmal thrombosis occurred outside the coil mass, presumably a result of disruption of the intraaneurysmal flow pattern.

OBJECTIVES In a companion article, we synthesized current clinical and preclinical data to formulate hypotheses about the etiology of drug administration catheter-tip inflammatory masses. In this article, we communicate our recommendations for the detection, treatment, mitigation, and prevention of such masses. METHODS We reviewed published and unpublished case reports and our own experiences...

This work treats the problem of dynamic modeling and state space approximation for robotic manipulators with flexibility. Case studies are planar manipulators with a single flexible link together with clamped-free ends and tip mass conditions. In this paper, complete dynamic modeling of the flexible beam without premature linearization in the formulation of the dynamics equations is developed, ...
