Treatment of Eyelid Ptosis due to Kearns-Sayre Syndrome Using Frontalis Suspension
Blepharoptosis is a common indication for surgery in plastic surgery units, yet its possible underlying pathology frequently remains unidentified. A 52-year-old man with a 20-year history of progressive bilateral ptosis (right>left) presented with recurrent ptosis of both eyes; he had undergone an operation on the levator aponeurosis 12 years prior. Due to the suspicion of an underlying disease, he was evaluated further. Chronic progressive external ophthalmoplegia in transition to the more severe syndromic variant Kearns-Sayre syndrome, a mitochondrial disorder causing myopathy, was diagnosed. The patient was treated with coenzyme Q10, and he underwent ptosis surgery on both eyes. This case illustrates a potentially multi-systemic disease that was diagnosed by a further evaluation of a common symptom, in this case worsening blepharoptosis. Awareness of myopathic symptoms is necessary to prevent overlooking serious yet improvable conditions
Are Genetics the Predicting Factor for the Success of Migraine Surgery? A Report on Identical Twins
Summary: Migraine affects more than 1 billion people globally, with distinct genetic variations influencing susceptibility. Thereby, genetic variations play a key role in the probability of developing migraine. However, personalized genetic analysis-based treatment options in migraine treatments are limited. Notably, surgical deactivation of extracranial trigger has shown efficacy in the treatment of migraine patients with identifiable trigger points in specific anatomical locations in the head and neck region.We present the first case of monozygotic twin sisters, both experiencing occipital and temporal-triggered migraine headaches with identical history and characteristics and without response to conservative migraine treatments. After surgical intervention, targeting the greater and lesser occipital nerves as well as auriculotemporal nerves, both twin sisters exhibited an over 99% reduction in symptoms without postoperative complications. This case suggests a potential correlation between genetic background, irrespective of environmental factors, and the effectiveness of surgical deactivation of trigger points in migraine management
Free anteromedial thigh flap: clinical application and review of literature
The anteromedial thigh (AMT) flap is reviewed in terms of its vascular anatomy and previous clinical reports in the literature. Our own series of 5 patients treated with this flap for defects in the head and neck region and lower extremity is presented. Although several authors controversially discussed vasculature, we constantly found the pedicle as an emerging septocutaneous perforator at a point where the medial border of the rectus femoris muscle is crossed by the sartorius muscle. In all 5 patients, the AMT flap provided stable coverage with no flap loss. Based on our findings, we conclude that the anteromedial thigh flap offers all the advantages of fasciocutaneous flaps. Therefore, we recommend this flap as an alternative for defects requiring coverages of thin to moderate skin thickness. However, it should be remembered that variations in vascular anatomy are possible
Microsurgical repair of the sural nerve after nerve biopsy to avoid associated sensory morbidity: a preliminary report
OBJECTIVE: The purpose of this article is to report our preliminary results regarding microsurgical repair of the sural nerve after nerve biopsy, in an attempt to reduce the well-described sensory morbidity and neuroma formation. METHODS: Three patients with a suspected diagnosis of peripheral neuropathy underwent sural nerve biopsies to establish definitive diagnoses. A 10-mm segment of the sural nerve was resected with local anesthesia. After harvesting of the specimen, the proximal and distal nerve stumps were carefully mobilized and united with epineural suture techniques, under a surgical microscope. Sensory evaluations (assessing the presence of hypesthesia/dysesthesia or pain) of the lateral aspect of the foot, in regions designated Areas 1, 2, and 3, were performed before and 6 and 12 months after the biopsies. A visual analog scale was used for pain estimation. RESULTS: The biopsy material was sufficient for histopathological examinations in all cases, leading to conclusive diagnoses (vasculitis in two cases and amyloidosis in one case). The early post-biopsy hypesthesia, which was present for 4 to 8 weeks, improved to preoperative levels as early as 6 months after the nerve repair. Sensory evaluations performed at 6- and 12-month follow-up times demonstrated that none of the patients complained of pain at the biopsy site or distally in the area innervated by the sural nerve. Ultrasonography performed at the 12-month follow-up examination revealed normal sural nerve morphological features, with no neuroma formation, comparable to findings for the contralateral site. CONCLUSION: Microsurgical repair of the sural nerve after biopsy can eliminate or reduce sensory disturbances such as paraesthesia, hypesthesia, and dysesthesia distal to the biopsy site, in the distribution of the sensory innervation of the sural nerve, and can prevent painful neuroma formation. To our knowledge, this article is the first in the literature to report on microsurgical repair of the sural nerve after nerve biopsy. Decreased side effects suggest that this technique can become a standard procedure after sural nerve biopsy, which is commonly required to establish the diagnosis of various diseases, such as peripheral nerve pathological conditions, vasculitis, and amyloidosis. More cases should be analyzed, however, to explore the usefulness of the technique and the reliability of sural nerve biopsy samples in attempts to obtain conclusive diagnoses
From Mice to Men : An Evolutionary Conserved Breakdown of the Epidermal Calcium Gradient and Its Impact on the Cornified Envelope
In previous publications, we could establish that a hallmark of human skin aging is the breakdown of the epidermal calcium gradient. This redistribution of calcium has many implications, including a restructuring of the cornified envelope, a reduced epidermal barrier function, a change in lipid composition, a reduced skin hydration, and an increased skin pH. Especially the age-dependent change in the cornified envelope composition was solely studied in human foreskin samples. The aim of this study was to confirm that this effect is neither restricted to UV-protected skin area nor limited to a specific sex. In addition, we wanted to show that the collapse of the epidermal calcium gradient is not only a hallmark of human skin aging, but is also evolutionarily conserved in mammals. By using such techniques as IHC, Western blot analysis, and RT-PCR, we could demonstrate the following: (1) A change in the epidermal calcium gradient is in fact the most important sign of epidermal aging in mammals (as shown in female human eyelids and mouse skin samples of the external ear-shell); (2) The disturbed calcium homeostasis affects the expression and crosslinking of most cornified-envelope-specific genes such as loricrin and filaggrin. In this way, we could establish that the age-dependent altered composition of the cornified envelope is a typical sign of skin aging not only in humans, but in mice, too. This makes the mouse an important model organism to study these changes.(VLID)284485
Age and Overweight Are Not Contraindications for a Breast Reconstruction with a TMG-Flap—A Risk and Complication Analysis of a Retrospective Double Center Study Including 300 Patients
Introduction: The transverse myocutaneous gracilis (TMG) flap has become a popular and reliable alternative for autologous breast reconstruction. Initially described as a valuable tissue source for women with low body-mass index, indications nowadays have widely expanded. The Western civilization demographic development with its aging population and the steady growing average BMI has led to increasing breast reconstructions with TMG flaps in overweight and aged individuals. Patients and Methods: A total of 300 TMG free flaps for unilateral autologous breast reconstruction were evaluated in the form of a retrospective double center cohort study. Data extraction, study group formation and statistical analysis (One-way analysis of variance (ANOVA), Pearson’s chi-squared statistical analysis and relative risk calculation) were done specifically to evaluate age and BMI as risk factors for postoperative complications and outcome. Results: No significant differences in patients’ age and BMI in the complication groups compared to the no-complication group could be found. No significant difference regarding the occurrence of complications could be found in any of the formed risk-groups. No significant increase of minor-, major- or overall complications, flap loss or revision surgeries were found in the elderly patient groups or for patients with overweight. Conclusion: Age and overweight do not significantly increase the risk for postoperative complications after breast reconstructions with free TMG flaps. The findings of this study support the fact that microsurgical breast reconstruction with a free TMG flap should not solely be reserved for younger patients and females with a lower BMI
