Phenomenology of the Electron Structure Function
Advantages of introducing the electron structure function (ESF) in electron
induced processes are demonstrated. Contrary to the photon structure function
it is directly measured in such processes. At present energies a simultaneous
analysis of both the electron and the photon structure functions gives an
important test of the experimentally applied methods. Estimates of the ESF at
currently measured momenta are given. At very high momenta contributions from
and bosons together with - interference can be observed.
Predictions for next generation of experiments are given.Comment: 6 pages, 4 figures New version, new figures adde
The use of botulinum toxin (BoNT) in urology - review
Introduction and purpose
Botulinum neurotoxin (BoNT) prevents the release of acetylcholine into the synaptic cleft of the neuromuscular junction, which causes flaccid muscle paralysis. A non-obvious specialization that uses botulinum toxin is urology. The aim of this article is to present a literature review regarding the use of botulinum toxin in the treatment of urological diseases.
Description of the state of knowledge
In the overactive bladder syndrome, with resistance to oral medications, an alternative is botox injections into the bladder wall, which reduce the intensity of urgency and pollakiuria.
Treatment of BPH with botulinum toxin injection may be an alternative to surgical and pharmacological treatment. Intra-articular botox injection causes smooth muscle relaxation and gland atrophy through prostate tissue apoptosis.
Clinical studies show promising therapeutic effects of using Botox injections in the treatment of intramural cystitis. It reduces the feeling of bladder pain and the worsening of other symptoms.
Panunzio et al. Presented a meta-analysis of prospective studies that showed a statistically significant improvement in pain perception after injection of botulinum toxin into the pelvic structures, compared with baseline values ​​for CPPS, in all cohorts evaluated.
Summary
Urology uses the entire spectrum of botox possibilities, from myocrelation in the bladder hyperresponsiveness syndrome, through neuromodulation and apoptosis induction in benign prostatic hyperplasia, ending with anti-inflammatory and analgesic properties in bladder pain syndrome and chronic pelvic pain syndrome
HA (hyaluronic acid) fillers in aesthetic medicine - the most common complications
Introduction and purpose
Hyaluronic acid (HA) is a polysaccharide consisting of the disaccharide units of glucuronic acid and N-acetylglucosamine. The age-related changes in the different anatomical layers of the face can be treated with hyaluronic acid fillers. Knowing the predictable aging changes of the face is crucial as this guides the optimum filler choice. HA is currently the most common used filler worldwide.
The aim of the study is to discuss the most common complications following aesthetic medicine treatments with the use of hyaluronic acid.
Description of the state of knowledge
Filling soft tissues with hyaluronic acid is a popular procedure in the field of aesthetic medicine for patients who want non-invasive rejuvenation. Among the numerous fillers, those with hyaluronic acid (HA) have many advantages: HA is easy to use and its effect is reversible. HA fillers are considered safe, although there may be complications such as: allergic reactions, infections, granulomas, nodules, tyndall effect, ecchymosis and skin necrosis. Many complications with the HA filler are correctable, for example: too little formulation, over-correctionand, asymmetry. Hyaluronic acid fillers are examples of reversible dermal fillers as they can be removed with hyaluronidase.
Summary
Avoiding complications is a top priority and must start with a thorough understanding of the anatomy followed by a precise injection technique. The ability to recognize complications and manage protocols will allow for their effective treatment
Botulinum toxin (BoNT) in the correction of mimic wrinkles - the most common complications
Introduction and purpose
Botulinum toxin (BoNT) products are commonly used to treat muscle spasms such as cervical dystonia as well as to treat expression lines. Serotype A of botulinum toxin is the strongest and is used in aesthetic medicine procedures. It provides predictable results while having few side effects. Nevertheless, complications may occur, such as: ptosis of the upper eyelid, drooping eyebrows, ectropia, double vision, xerophthalmia, falling corners of the mouth, dysphagia, hoarseness, local swelling, erythema, bruising, pain at the injection site, asymmetry.
The aim of the study is to discuss the most common complications after injection of the botulin toxin in the correction of mimic wrinkles.
Description of the state of knowledge
BoNT is a neurotoxin that acts on the neuromuscular junctions, inhibits the release of acetylcholine, consequently causing temporary chemical denervation. Muscle function begins to return approximately 3 months after injection and fully returns after 6 months. Comparison of clinical trials of botulinum toxin type A in aesthetic allowed for the quantification of the frequency of adverse effects:drooping eyelids (2.5%), drooping eyebrows (3.1%), disturbed eye sensation (3%) and lip asymmetry (6.9%). Complications after cosmetic botulinum toxin injections are rare, and those that do occur are usually mild and transient. These complications are technique dependent; the incidence decreases as the injection ability improves.
Summary
Side effects are rare, nevertheless, thorough knowledge of the patient's anatomy, medical history, possible complications related to the specific product and site of administration, and close monitoring are essential for safe, effective treatment and the achievement of satisfactory results
