A Systematic Quality Assessment of Online Resources on Eyelid Ptosis Using the Modified Ensuring Quality Information for Patients (mEQIP) Tool.

BACKGROUND: Eyelid ptosis is an underestimated pathology deeply affecting patients' quality of life. Internet has increasingly become the major source of information regarding health care, and patients often browse on websites to acquire an initial knowledge on the subject. However, there is lack of data concerning the quality of available information focusing on the eyelid ptosis and its treatment. We systematically evaluated online information quality on eyelid ptosis by using the "Ensuring Quality Information for Patients" (EQIP) scale. MATERIALS AND METHODS: Google, Yahoo and Bing have been searched for the keywords "Eyelid ptosis," "Eyelid ptosis surgery" and "Blepharoptosis." The first 50 hits were included, evaluating the quality of information with the expanded EQIP tool. Websites in English and intended for general non-medical public use were included. Irrelevant documents, videos, pictures, blogs and articles with no access were excluded. RESULTS: Out of 138 eligible websites, 79 (57,7%) addressed more than 20 EQIP items, with an overall median score of 20,2. Only 2% discussed procedure complication rates. The majority fail to disclose severe complications and quantifying risks, fewer than 18% clarified the potential need for additional treatments. Surgical procedure details were lacking, and there was insufficient information about pre-/postoperative precautions for patients. Currently, online quality information has not improved since COVID-19 pandemic. CONCLUSIONS: This study highlights the urgent requirement for improved patient-oriented websites adhering to international standards for plastic and oculoplastic surgery. Healthcare providers should effectively guide their patients in finding trustworthy and reliable eyelid ptosis correction information.

Medial fascia lata perforator flap: Anatomical basis and clinical application as a pedicled or free flap.

Adipofascial flaps have proven to be an excellent tool for multipurpose reconstruction as free or pedicled flaps. The anatomical studies in this field are now focused on improving esthetics in reconstruction while maintaining a minimal donor site morbidity. An anatomical cadaver study has been carried out to investigate the medial thigh region as a potential donor site for adipofascial flaps. Eighteen thighs from fresh cadavers were dissected and a new territory with autonomous vascular supply was defined through vascular injection, anatomical dissection, transillumination, and angiography. Cutaneous access was made in a "T" shape. The fascia harvests had to be centered on the adductor longus and gracilis muscles bearing in mind the position of the flap pedicle. The fascial flap was isolated from adductor longus and gracilis muscles and isolated on his pedicle (medial circumflex femoral artery). After our anatomical study, we used the flap in 2 clinical cases. The results of our anatomical study and clinical cases confirmed the suitability and reliability of a new flap: the "Medial Fascia Lata Flap." Flap size ranged from 20 to 25 cm and has the advantage of preserving the functionality of the thigh muscles. The study showed that the "Medial Fascia Lata Flap" is easy to harvest, and the resulting scar is concealed. In consideration of its suitability, reliability and aesthetical advantages, it could be proposed as a good option in selected cases.

Energy-Based Devices Affect the Aesthetic Outcome of Cervical Thyroidectomy and Parathyroidectomy. A Retrospective Study.

INTRODUCTION: Thyroid and parathyroid diseases are very common. Most of these cases are in women and may be amenable to surgery. The patient's perception that these are not life-threatening diseases leads them to expect an excellent aesthetic result, since the surgical incision area is clearly visible. OBJECTIVE: To evaluate different scarring outcomes using three different energy-based devices (Harmonic Focus®, Johnson & Johnson, New Brunswick, NJ; Thunderbeat Open Fine Jaw®, Olympus Medical, Tokyo, Japan; LigaSure Small Jaw®, Medtronic, Dublin, Ireland) and to determine the impact of post-thyroidectomy/parathyroidectomy scars on the patient's quality of life. METHODS: One hundred female patients who underwent thyroidectomy or parathyroidectomy between September 2017 and September 2019 at the Endocrine and Minimally Invasive Surgery Department of Messina University Hospital were recruited. A retrospective analysis assessed the thickness of the cervical scar via ultrasound imaging, and the patient's degree of satisfaction through the Patient and Observer Scar Assessment Scale (POSAS) and the Body Dysmorphic Disorder Questionnaire (BDDQ). RESULTS: The patients were divided into three groups according to the energy-device used: group A (LigaSure SJ (n=38), group B (Harmonic F, n=32) and group C (Thunderbeat OFJ, n=30). The three groups were homogeneous with respect to number of patients, age and surgical procedures. The best aesthetic result, which correlated with the lowest scar thickness, was observed in group A; these patients were more satisfied than those in the other two groups. Moreover, correlations between scar thickness and quantitative variables (such as age or BMI) were not found in any of the groups. CONCLUSIONS: Based on the data collected and our experience, the LigaSure Small Jaw® (Medtronic) seems to offer the best aesthetic outcome in patients who undergo transverse cervicotomy for thyroid and parathyroid diseases. However, further prospective studies involving a greater number of cases are needed.

ROS as Regulators of Cellular Processes in Melanoma.

In this review, we examine the multiple roles of ROS in the pathogenesis of melanoma, focusing on signal transduction and regulation of gene expression. In recent years, different studies have analyzed the dual role of ROS in regulating the redox system, with both negative and positive consequences on human health, depending on cell concentration of these agents. High ROS levels can result from an altered balance between oxidant generation and intracellular antioxidant activity and can produce harmful effects. In contrast, low amounts of ROS are considered beneficial, since they trigger signaling pathways involved in physiological activities and programmed cell death, with protective effects against melanoma. Here, we examine these beneficial roles, which could have interesting implications in melanoma treatment.

Distal nerve transfer from the median nerve lumbrical fibers to the distal ulnar nerve motor branches in the palm: An anatomical cadaveric study.

BACKGROUND: The aim of the current study is to investigate the first and second lumbrical nerves as potential fibers donors to the deep motor branch of the ulnar nerve to avoid intrinsic atrophy in high ulnar nerve injuries. METHODS: Sixteen fresh frozen cadaveric hands were dissected, the radial lumbrical nerves accessed, and a coaptation, either in reverse end-to-side or in double end-to-side through a bridge nerve graft, was created to the deep motor branch of ulnar nerve. Semithin sections were taken from samples of donor and recipient nerves for qualitative (nerve architecture) and quantitative studies (fiber count and donor/recipient ratio). RESULTS: The first lumbrical showed a robust trunk and a superior axon density (9,126.50 ± 2,923.41 axons/mm2 ) to the ulnar motor branch (7,506.50 ± 1,137.50 axons/mm2 distal to the opponens tunnel and 7,947.75 ± 1,741.24 axons/mm2 before its terminal branching); the ulnar motor branch showed a higher axon number (2,633.51 ± 410.00 distal to the opponens tunnel and 2,345.75 ± 2,101.56 before its terminal branching) than the first lumbrical (1,410.56 ± 823.89); section areas occupied by axons were higher in proximal (0.20 ± 0.16) and distal (0.26 ± 0.20) ulnar samples than the first lumbrical (0.17 ± 0.16). Donor/recipient ratio first lumbrical/deep motor branch of the ulnar nerve were 1:1.86 (distal to the opponens tunnel) and 1:1.67 (at its terminal branching); data about the second lumbrical were ruled out because of bias. CONCLUSIONS: A transfer from the first lumbrical nerve to the deep motor branch of the ulnar nerve in palm is suitable to avoid intrinsic atrophy.

Is the adipofascial flap the key to regenerative surgery?

OBJECTIVES: "Form and function restoration" is the ultimate goal of reconstructive surgery, which is oriented toward regeneration rather than reparation. Recently, research in reconstructive surgery has focused on the regenerative potential of the adipose tissue. The aim of the study is to illustrate the surgical methods and show the functional and aesthetic results achieved by the reconstruction of finger soft-tissue defects using homodigital dorsal adipofascial reverse flap (HDARF). MATERIALS AND METHODS: A total of 63 cases (45 acute and 18 elective) were included between September 2010 and August 2016. In each case, we preliminarily performed surgical debridement and then harvested an adipofascial flap from the back of the finger. Nine injured thumbs that were repaired with the flap as emergency cases were also included. The average age of the patients was 46 (range: 4-69) years. RESULTS: All flaps survived without any complications during the 24-month follow-up. Good nail regrowth through the flap and full regeneration were observed in approximately all cases. Sensitivity tests and histological analysis of biopsy samples of the regenerated fingers confirmed full regeneration of the epidermis, dermis, cutaneous adnexa, and nerves. All the patients were satisfied with the hand functionality and aesthetic appearance. CONCLUSION: The HDARF represents a very useful alternative for the reconstruction of nailbed crushes, achieving regeneration of injured segments in deformities caused by trauma or infection.

The reasons for end-to-side coaptation: how does lateral axon sprouting work?

Nerve fibers are attracted by sutureless end-to-side nerve coaptation into the recipient nerve. Opening a window in the epineurium enhances axon attraction and myelination. The authors analyze the features of nerve repair by end-to-side coaptation. They highlight the known mechanisms of axon sprouting and different hypotheses of start up signals (presence or absence of an epineurial window, role of Schwann cells, signaling from the distal trunk). The clinical literature is also presented and differences between experimental and clinical applications are pointed out. The authors propose their point of view and perspectives deriving from recent experimental and clinical experiences.

Lipograft in cicatricial ectropion.

AIM: Cicatricial ectropion is secondary to an excessive scar contraction after trauma, burns, skin conditions, scarring skin tumours, medication, allergies, blepharoplasty complications 1,2. The estimates for ectropion incidence following removal of eyelid lesions have been reported as varying from 2.5% to 7% 3. A variety of surgical techniques can be applied to achieve the correct shape and position of lower lid 4-7. Fat grafts in association with other technique are commonly used in orbital reconstruction in a variety of procedures 8 including of the correction of cicatricial ectropion 9,10. MATERIAL OF STUDY: The Authors propose the use of fat graft as only procedure for the correction of cicatricial lower eyelid ectropion. Two male patients with cicatricial ectropion were treated with this technique in two time and followed for 12 months. RESULTS: Lipofilling for cicatricial eyelid ectropion give excellent outcomes, with release of the scar without recurrence, 11. DISCUSSION: Autologous fat grafting has many clinical applications, and its use in Plastic Surgery is increasing: The key point is the presence into fat of Adipose stem cells (ASCs), that have been identified as an ideal source of cells for regenerative medicine, with potential and rapid improvement of healing process and complete recovery of tissue integrity after surgery to confirm the regenerative effect of fat graft. CONCLUSION: Lipografting can be considered a safe and effective alternative procedure 12,13. KEY WORDS: Defect of lower lid, Ectropion, Lipograft.

Diffusion Tensor Imaging Tractography in Pure Neuritic Leprosy: First Experience Report and Review of the Literature.

Five years after both right ulnar and median nerve decompression for paraesthesias and palsy, a patient, coming from Nigeria but living in Italy, came to our unit claiming to have persistent pain and combined median and ulnar palsy. Under suspicion of leprosy, skin and left sural nerve biopsy were performed. Skin tests were negative, but Schwann cells resulted as positive for acid-fast bacilli (AFB), leading to the diagnosis of Pure Neuritic Leprosy (PNL). The patient was given PB multidrug therapy and recovered from pain in two months. After nine months both High Resolution Ultrasonography (HRUS) and Magnetic Resonance Imaging (MRI) were performed, revealing thickening of the nerves. Since demyelination is common in PNL, the Authors started to use Diffusion Tensor Imaging Tractography (DTIT) to get better morphological and functional data about myelination than does the traditional imaging. DTIT proved successful in showing myelin discontinuity, reorganization, and myelination, and the Authors suggest that it can give more information about the evolution of the disease, as well as further indications for surgery (nerve decompression, nerve transfers, and babysitting for distal effector protection), and should be added to traditional imaging tools in leprosy.

Elevator Muscle Anterior Resection: A New Technique for Blepharoptosis.

Blepharoptosis is a condition of inadequate upper eyelid position, with a downward displacement of the upper eyelid margin resulting in obstruction of the superior visual field. Levator resection is an effective technique that is routinely used to correct aponeurotic ptosis. The anterior levator resection is the procedure of choice in moderate blepharoptosis when there is moderate to good levator muscle function, furthermore, with an anterior approach, a greater resection can be achieved than by a conjunctival approach. The authors describe a modification in the Putterman technique with a resection done over a plicated elevator, plication that was suggested by Mustardè. The technique has been named as elevator muscle anterior resection. The elevator muscle anterior resection inspires from the Fasanella-Servat operation by the use of a clamp, making the operation simple and predictable.

Anatomical and aesthetical reconstruction of complex hair-bearing areas: a three-step procedure including implant of dermal regeneration templates, skin grafting, and hair micrografting.

Reconstructive surgery of complex hair-bearing skin defects often represents a challenge for the plastic surgeon; indeed, a multistage procedure is to be planned, including a first reconstructive step including local flaps, even if pre-expanded, or for larger defects, microsurgical flaps. To date, the implant of dermal regeneration templates has been proven an effective alternative. The authors relate their results of a complex hair-bearing reconstruction of a scalp and brow defect after a friction road burn with those reported in literature, concluding that a 3-staged reconstruction (dermal template implantation, skin grafting, and finally hair micrografting) can achieve good results in this complex kind of reconstruction. Histological specimens taken 2 years later confirmed a full anatomical reconstruction of the hair-bearing areas. Finally, this paper reports the first case of brow reconstruction performed with these techniques.

A free vein graft cap influences neuroma formation after nerve transection.

INTRODUCTION: : Neuroma formation is a major problem in nerve surgery and consensus about its prevention has not been reached. It has been suggested that vein covering can reduce neuroma formation in transected nerves. In this article, the Authors propose an easy and novel method of covering by nerve stump capping with a free vein graft. METHODS: : Neuroma-like lesions were created on the rat thigh sectioning the femoral nerve above its division in 16 animals. The proximal nerve stump was invaginated into the lumen of a 1.5 cm long femoral free vein graft on the right side, and the vein was closed on itself by microsurgical sutures to form a cap for the nerve stump. On the left side acting as the control neuroma, the nerve was cut and left uncovered. Histological and immunohistochemical assessment was used to quantify the degree of neuroma formation. RESULTS: : Significant differences were found in both neuroma size and axon-glia organization between the treated and control sides indicating that free vein graft capping reduced neuroma formation in comparison to uncovered nerve stumps. CONCLUSIONS: : Our results confirm that vein-covering of a transected nerve stump can be effective in reducing neuroma formation. Moreover, unlike previous works that buried the nerve into an adjacent vein left in place, our experiments showed that also the use of a free vein graft cap can hinder neuroma formation. Although translation of rat experiments to the clinics should be dealt with caution, our data suggest a careful clinical use of the technique. (c) 2009 Wiley-Liss, Inc. Microsurgery, 2009.

An anterior-lateral thigh perforator flap on a recipient brachial-radial vein graft for complex wound reconstruction: a case report.

A case of challenging microsurgical reconstruction of a difficult defect in a radiated upper limb is reported. A difficult wound, with tendon and bone exposition, developed on the dorsum of the forearm in a 76-year-old patient; she had been radiated since almost 50 years and her left hand had also been revascularized twice with venous grafts between the humeral artery and the superficial palmar arch. After failure of a local flap, an anterior-lateral thigh perforator flap was successfully transferred with end-to-side anastomoses on the arterialized venous graft. Up to date follow-up shows a good outcome. The Authors discuss the case and review the indications for microsurgical reconstruction in difficult wounds after radiation and ischemic limb conditions.

Location of communicating veins for medial plantar venous flap.

BACKGROUND: The medial plantar venous flap is suitable for reconstruction of the palmar surface of the finger. However, it is sometimes difficult to detect and harvest the distal subcutaneous vein of the flap. In such a situation, the communicating vein can be used as a distal vein for the flap. However, the location of these veins is not obvious. METHODS: By using 20 feet from 10 cadavers and ultrasound imaging for 40 feet from 20 healthy individuals, we investigated the location of communicating veins. RESULTS: In cadavers, 11 communicating veins (45.8%, n = 24) were located in the area above the abductor hallucis muscle and 12 veins (50%) in the area below it. Ultrasound imaging revealed 15 bifurcations of the communicating veins (31.3%, n = 48) in the upper area and 27 bifurcations in the lower area of the medial plantar region (56.3%). CONCLUSION: It was observed that the communicating veins were concentrated in the areas above and below the abductor hallucis muscle.

The use of sentinel node biopsy and selective lymphadenectomy in squamous cell carcinoma of the upper limb. Usefulness of sentinel node biopsy to avoid useless lymphadenectomies in high-risk upper limb SCC.

BACKGROUND: Squamous cell carcinoma (SCC) is the second most common skin cancer in humans. Because the incidence of metastasis from SCC of the skin is rare, regional lymphadenectomy is generally not recommended for the patients with clinically node-negative disease. However, in patients with an intermediate and high risk of metastasis, evaluation of the lymph nodes to detect the absence of metastatic nodal disease is a difficult task. PATIENTS AND METHODS: The authors reviewed the pertinent demographic and surgical data in a consecutive series of six patients with squamous cell carcinoma who underwent sentinel lymph node staging. The tumour size was greater than 2 cm (T2) and the patients had clinically non-palpable regional lymph nodes (N0). All nodes were examined using haematoxylin-eosin staining. Sentinel Lymph Node Biopsy (SLNB) and Selective Lymphadenectomy (SL) using preoperative lymphoscintigraphy and intraoperative radiolymphoscintigraphy and vital dye injections was used to identify the sentinel lymph node avoiding complete axillary node dissection. RESULTS: No false-negative results were observed. At a median follow-up of 10 months (mean 15 months), neither local or regional recurrences in sentinel node-negative basins have been noted. CONCLUSIONS: Sentinel node biopsy is a minimally invasive staging procedure useful in identifying occult regional lymph node disease in selected patients with squamous cutaneous malignancies of the arm. Furthermore sentinel lymph node histology is possibly the most important negative predictor of early recurrence and survival in patients with American Joint Committee on Cancer stage I and II squamous cell carcinoma. Although sentinel node-negative patients are a prognostically favourable group, this small series of patients demonstrates that further studies to verify these findings and develop formal guidelines are indicated

The distally based sural flap for lower leg reconstruction: versatility in patients with associated morbidity.

INTRODUCTION: Coverage of soft tissue defects in the lower leg is often made by use of free flap, also because of the improving of anaesthesiology techniques in the last decades. However, there are disadvantages in the use of free flaps like the need for a remote donor site, increased operative time, use of a major vessel to the leg, and microsurgical skills. Besides these, trauma in the lower limb are often cause of damage for a major vessels of the leg, so the use of free flaps in these patients may be related to an higher incidence of complications; also associated pathologies, like diabetes and vascular pathology, can increase the incidence of complications when a free flap is utilized. In all these cases local fascio-cutaneous flaps, like the sural reverse flap, because of their easy and short time harvesting, can be a very good alternative to free flaps. Superficial sural artery flap is a adipofasciocutaneous flap based on the vascular axis of the sural nerve, which gets reverse blood flow through communication with the perforating branch of the peroneal artery, situated in the region of lateral malleolar gutter. PATIENTS AND METHODS: Between 2000 and 2005, 11 patients, mean age 68 (range 58-78 years), were treated at the Plastic and Reconstructive Surgery Unit of Messina University, for soft tissue defects of lower limb and foot, using the distally based sural artery flap. The defects were related to post-traumatic damage of soft tissue, diabetic and vascular ulcers, osteomyelitis and oncological resection. Mean follow-up time was 20 months (range 6-55 months). All patients were pre-operatively assessed for vascular patency of peroneal axis and associated morbidity that could increase risk offlap necrosis. This included diabetes mellitus type II, osteomyelitis and peripheral arterial diseases. RESULTS: All flaps survived with the exception of one that sustained partial skin necrosis, in the ratio of 25% of the skin island. All defects were covered with no major complications and none of the patients required a blood transfusion. Moreover aesthetic results were good with satisfaction of all the patients. CONCLUSION: In our cases we found the sural reverse flap to have a good reliability with low incidence of complication and surgical outcomes. This flap is an excellent option for covering defects of minor deficiency of skin in the third distally of lower limb, ankle and heel. It allows rapid, reliable coverage of defects extending as far distally as the forefoot. Because of the sparing of major vessels, the short surgery time in harvesting the flap, and the good vascular pattern of the flap, we retain the flap a first choose technique for reconstruction in lower leg, especially in politrauma and in patients with associated pathology as vascular diseases or diabetes.

Microsurgical arterovenous loops and biological templates: a novel in vivo chamber for tissue engineering.

BACKGROUND: Microsurgical tissue engineering is an emerging topic in regenerative medicine. Here we describe a new microsurgical model of bioengineering in rats based on the use of an arterovenous loop (AV) implanted into a commercially available crosslinked collagen/glycosaminoglycan template. METHODS: The microvascular loop was created between the femoral artery and vein and covered by the template folded onto itself. The chamber was isolated from the outside tissue by an outer silicon layer to impede tissue ingrowth. RESULTS: At 1-month postimplantation, the tissue chamber was found heavily vascularized, as assessed by laser Doppler perfusion analysis. Histological examination showed that the AV loop was integrated into the collagen matrix of the template and that the whole template was filled with a newly formed soft connective tissue. Most interestingly, the whole scaffold was found heavily vascularized, including the formation of a large number of alpha-SMA-positive arterioles. CONCLUSIONS: The developed microsurgical chamber provides a highly vascular, isolated tool for in vivo tissue engineering.

Selection of the donor nerve for end-to-side neurorrhaphy.

OBJECT: The authors of other studies have reported that the selection of an agonistic donor nerve is required for recovering voluntary motor control after end-to-side nerve repair. In this experimental investigation, the authors' goal was to verify this assumption by performing end-to-side neurorrhaphy of the rat median nerve on its antagonistic radial nerve. METHODS: The left median nerve in 10 adult female rats was repaired by end-to-side neurorrhaphy after epineuriotomy on the radial nerve at the middle of the brachium. The time course of median nerve functional recovery was then assessed using the grasping test until postoperative Week 30. Before removing the nerve, the surgical site was carefully explored to exclude contamination by the proximal nerve stump, and the functional anatomy of median and radial nerves was assessed by electrical stimulation. Repaired nerves were then processed for resin embedding, and semithin sections were obtained for nerve fiber histomorphometry by using the dissector method. RESULTS: Repaired median nerves were repopulated by nerve fibers regenerating from the radial donor nerve as previously shown. Moreover, voluntary motor control of the flexor muscles innervated by the median nerve was progressively recovered beginning in postoperative Week 10 and reaching 42% of normal by Week 30. CONCLUSIONS: Contrary to previously reported data, recovery of voluntary motor function after end-to-side nerve repair can also be expected when an antagonistic nerve is used as a donor nerve.
