Deactivation of Temporal Trigger Sites
No full textInflammation of temporal trigger sites is a common cause of migraine. The authors detailed their surgical approach (ligation of the superficial branch of the temporal artery) to relieve compression of the auriculotemporal nerve
A three-year experience with medial-pedicle-based breast reduction for different mammary hypertrophy
No full textCONCLUSIONS: Breast reduction surgery must address both functional and aesthetic issue by restoring an aesthetically pleasing shape to ptotic or hypertrophic breasts, repositioning the NAC in a physiological position. Various breast reduction techniques have been attempted to combine the safety of the pedicle with aesthetic and functional results. Surgeons should tailor the best technique to each patient. We found that medial-pedicle-based reduction mammoplasty is effective and reliable because it can be applied to a wide range of breast hypertrophy, with reproducible breast weight reduction and results that are aesthetically satisfactory for both patients and surgeons.BACKGROUND AND AIM: The aim of breast reduction is to reduce excessive breast volume, ensuring an adequate vascular supply and sensitivity of the nipple-areola complex, as well as to produce an aesthetically pleasing final shape. The authors report on their experience with medial-pedicle-based breast reduction combined with both vertical and inverted-T skin resection patterns for different types of breast hypertrophy.METHODS: From January 2012 to June 2015, 27 female patients (mean age: 49 years) underwent reduction mammoplasty with the medial pedicle technique. The choices of medial pedicle base widths were: 6 cm for low-grade mammary hypertrophy (350-500 gr per breast), 6-8 cm for medium-grade hypertrophy (500-1000 gr per breast), or 8-10 cm for severe mammary hypertrophy (>1000 gr per breast). The authors chose the model of vertical skin resection for low-grade breast hypertrophy. The vertical model was used for medium-grade breast hypertrophy, and Wise skin resection was chosen on a case-by-case basis; only the Wise model was applied to severe breast hypertrophy. Results: The mean weight of breast excised was 540 g on the left (range, 207 to 1160 g) and 564.8 g on the right (range, 215 to 1150 g). The complications were minor and self-limiting. All patients reported relief of neck pain, back pain, and bra strap indentations after 6 months of follow-up
Surgical deactivation of occipital migraine trigger site
No full textBACKGR OUND: Following the pioneering work of Guyuron et al. in 2001, an impressive body of literature demonstrated that the inflammation of peripheral nerves caused by chronic compression from surrounding structures (e.g., muscles, blood vessels) might trigger migraines. In this study, we report our experience with a minimally invasive surgical procedure for occipital migraine headache treatment. METHODS: From June 2011 until January 2019, we performed 246 MH decompression surgeries in patients with either frontal, occipital, or temporal migraine trigger sites. Among them, 130 surgeries were performed to treat occipital migraine (90 bilateral and 40 unilateral). In 108 occipital migraines, we found a dilated occipital artery in close connection with the greater occipital nerve (GON) and we ligated the vessel without any other surgical manoeuvres. R ESULTS: After a mean follow-up of 21 months (range: 3-67 months), patients with occipital migraine had positive response in 94.9% (86.8% complete relief and 8.1% significant improvement), and 5.1% did not get any better. CONCLUSIONS: Occipital migraine is a common and debilitating condition that can be treated successfully with surgery. According to our experience, a dilated occipital artery is usually responsible for nerve compression, mostly the greater occipital nerve. Clinical outcome of our surgical procedure based on artery ligation seems to prove the validity of this hypothesis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Oncoplastic breast surgery: comprehensive review
No full textBreast cancer is the most common female cancer in Western populations, affecting 12.5% of women, with 1.38 million patients per year. Breast-conserving surgery followed by postoperative radiotherapy replaced the radical and modified-radical procedures of Halsted and Patey as the standard of care for early-stage breast cancer once the overall and disease-free survival rates of breast-conserving surgery were demonstrated to be equivalent to those of mastectomy. However, excision of >20% of breast tissue, low or centrally located cancer, and large-sized breasts with various grades of breast ptosis, result a in unacceptable cosmetic outcomes. Oncoplastic breast surgery evolved from the breast-conserving surgery by broadening its general indication to achieve wider excision margins without compromising on the cosmetic outcomes. Thus, oncoplastic breast surgery can be defined as a tumor-specific immediate breast reconstruction method that applies aesthetically derived breast reduction techniques to the field of breast cancer surgery and allows for higher volume excision with no aesthetic compromise. However, contralateral breast symmetrization should be regarded as an intrinsic component of the oncoplastic surgery. The main procedures involved are volume-displacement or volume-replacement techniques, which depend on breast size and cancer size/location. Volume-displacement or reshaping procedures apply the plastic surgery principles to transpose a dermo-glandular flap of breast tissue into the defect site, while volume-replacement techniques use autologous tissues to replace the volume loss that follows tumor resection. Furthermore, these procedures are more complex and time-consuming than those involved in breast-conserving surgery. Based on current literature, the authors analyze the different techniques and indications of the oncoplastic breast surgery, determining its complication rate, in order to help both surgeons and their patients in the decision-making stage of breast reconstruction
Activity Evaluation of Facial Muscles by Surface Electromyography
No full textBackground: Surface electromyography (sEMG) is an easy, noninvasive, and reproducible way to assess spontaneous electrical activity of muscles in real time. In this study, we report data on the correlation between sEMG and mimetic muscle activity during specific tasks so as to create a case-control reference for future studies on acute, chronic, and congenital facial palsy. Methods: Twelve healthy participants were enrolled (6 women and 6 men) with a mean age of 42.75 (range, 26-58 years) years. sEMG signals were recorded at rest and while performing voluntary and specific tasks that elicited selective contraction of frontalis, orbicularis oculi, zygomaticus major, orbicularis oris, and platysma muscles simultaneously and bilaterally for each muscle group. Statistical analysis was performed to evaluate if there was a statistically significant difference of the average contraction values between left- and right-side data sets and between male and female participants. Results: No statistically significant difference was found between male and female participants or between the right and left sides at rest and while performing the requested tasks, even though they were not identical. No participant complained about the procedure. Conclusions: Interindividual and intraindividual variability of the sEMG signal as well as crosstalk between muscles groups were reported downsides that we did not encounter. The absolute noninvasiveness of our procedure makes it feasible to be applied even to young children. This dataset obtained in healthy participants might also be useful in the observation of patients undergoing regeneration/reinnervation procedure following recently acquired facial palsy or mimetic muscle reconstruction for congenital/inveterate one
