Effect of perivascular low dose ethanol on rat femoral vessels: Preliminary study.

Vasospasm is one of the important causes of morbidity in free flap and replantation surgery. In secondary Raynaud's phenomenon, nearly half of the patients experience digital ulceration, pain and loss of function at least once in their lifetime. The aim of this study is to investigate the vasodilation effect of ethanol-mediated chemical denervation on peripheral vessels by topical administration. In this study, 27 Wistar albino male rats weighing 250-300 grams were used. The rats were randomly divided into three groups: saline (group S, n = 8), lidocaine (group L, n = 9) and 96% ethanol (group E, n = 9). According to group, 0.1 mL saline, 0.1 mL lidocaine and 0.1 mL ethanol were applied around the rat femoral neurovascular bundle. After the application, on the 0th day and 3th weeks, femoral artery and vein diameters were measured. After 3. weeks, histopathological samples from femoral artery, vein and nerve were evaluated. On the 0th day, the mean diameter of the femoral artery and vein was similar in group E and L and higher than group S. After three weeks, the vasodilatation effect of ethanol was increased in group E. In Group L and S, the vasodilatation effect was lost. Histopathological examination showed that ethanol significantly caused perivascular inflammation and nerve degeneration compared to other agents and did not cause endothelial damage. Vasodilatation obtained by ethanol is a rapid onset and long-lasting effect. It is also inexpensive and effective for peripheral vasodilatation.

Approach to Patients with Malignant Melanoma of Unknown Primary Origin.

OBJECTIVES: Although malignant melanoma accounts for 3% of skin cancers, it is responsible for 75% of deaths associated with skin cancer. In our study, all melanoma cases diagnosed and treated at our clinic were retrospectively reviewed, and the cases of unknown primary origin among them were examined in detail in terms of diagnosis and treatment. METHODS: The patients with malignant melanoma treated at the inpatient services of our clinic between January 1991 and April 2017 were retrospectively screened in the records. These patients were evaluated for age, sex, tumor type, Breslow depth, metastasis, and treatment. Among these patients, four cases of unknown primary origin were examined in detail. RESULTS: During January 1991 and April 2017, 173 patients received inpatient care for malignant melanoma at our clinic. As regards to the melanoma subtypes, nodular type in 45 patients, acral lentiginous type in 43 patients, superficial spreading type in 63 patients, lentigo maligna melanoma in 15 patients, subungual type in 7 patients, and either unidentified melanoma or other subtypes in 10 patients were identified. CONCLUSION: The ideal treatment of a patient with melanoma is multidisciplinary, with plastic surgery having a central role.

Predicting skin deficits through surface area measurements in ear reconstruction and adult ear surface area norms.

Ear reconstruction is one of the most challenging procedures in plastic surgery practice. Many studies and techniques have been described in the literature for carving a well-pronounced framework. However, just as important as the cartilage framework is the ample amount of delicate skin coverage of the framework. In this report, we introduce an innovative method of measuring the skin surface area of the auricle from a three-dimensional template created from the healthy ear.The study group consisted of 60 adult Turkish individuals who were randomly selected (30 men and 30 women). The participant ages ranged from 18 to 45 years (mean, 31.5 years), and they had no history of trauma or congenital anomalies. The template is created by dividing the ear into aesthetic subunits and using ImageJ software to estimate the necessary amount of total skin surface area required.Reconstruction of the auricle is a complicated process that requires experience and patience to provide the auricular details. We believe this estimate will shorten the learning curve for residents and surgeons interested in ear reconstruction and will help surgeons obtain adequate skin to drape over the well-sculpted cartilage frameworks by providing a reference list of total ear skin surface area measurements for Turkish men and women.

The feasibility of tissue expansion in reconstruction of congenital and aquired deformities of pediatric patients.

Skin expansion is one of the major developments in reconstructive surgery. The use of tissue expansion has been popularized among plastic surgeons and has become the treatment method of choice for many congenital and acquired defects in a wide variety of diseases in adults and then later in children. The authors analyze their clinical experience in the treatment of burn scars and complex defects by tissue expansion in pediatric patients. The study included thirty five expansion procedures performed in 25 patients. Smooth surface expanders with a remote valve were used in the scalp (22), face (2), neck (3), hand (2), thorax (2), breast (1), palate (2), abdomen (1). Self-inflating osmotic tissue expanders were used in four patients, one of them had cleft palate and the other two of them had congenital hand anomalies and the last one had frontal scar and alopecia in the frontal hairline. In 19 out of 25 cases (76%) tissue expansion was achieved without complications. At the same time, in 1 cases minor complications and in 5 cases major complications occurred. The number of expanders per patient was only one in 16 cases. More than one expander was used to remove parts of the same injury in 9 cases. Our study may help to draw attention again on different aspects in tissue expansion and critically focus on each step of the tissue expansion both using self-filling tissue expanders and smooth surface tissue expanders with a remote valve.

Anomalous large unique muscle belly of flexor digitorum superficialis and the absence of palmaris longus in the forearm.

Anomalies of muscles of the upper extremity are frequently encountered and anatomic variations of the flexor digitorum superficialis (FDS) muscle-tendon unit are frequently reported by anatomists and clinicians. FDS anomalies can be in forms of tendon interconnections, substitution, absence or muscle belly variations and most of the times the anomalies of FDS produce few clinical symptoms. We report a rare and unusual case of FDS anomaly with a unique and large muscle belly. The deformity is type V according to the classification of Elliot et al. in which the muscle belly extends to four digits (the index, middle, ring and little finger) in the right hand of patient and there is absence of the palmaris longus tendon. The hand surgeon should be able to realise all variations of the FDS tendon and should be prepared for unexpected findings during surgery.

Severe symmetrical facial lipoatrophy in a patient with discoid lupus erythematosus.

Acquired partial lipodystrophy is a rare disorder, and it is characterized by the absence of subcutaneous fat from the face, the neck, the trunk, and the upper extremities. The etiology of acquired partial lipodystrophy includes scleroderma and discoid lupus erythematosus. Literature review reveals studies involving 10 patients until today with lipoatrophy due to or after the onset of discoid lupus erythematosus; all are female patients. We want to report a young male patient with progressive symmetrical facial lipoatrophy. In addition, he has discoid lupus erythematosus and celiac disease. Fat grafting and adjuvant oral coenzyme Q10 tablets (Deka-none; Deka Pharmaceuticals, Istanbul, Turkey) were administered for treatment. To our knowledge, this case involves the first male patient in the literature presenting with symmetrical facial lipoatrophy with very prominent periorbital lipoatrophy and bitemporal hollowing symptoms.

Does vitamin B alter the efficacy of botulinum toxin?

Botulinum toxin prevents acetylcholine release at motor nerve terminals. Group B vitamins (B-vit) are essential for proper nerve function. The present study addresses the question of whether B-vit accelerate recovery in rat skeletal muscle after botulinum toxin A (Btx-A) injection. Forty-four adult male Wistar albino rats were used in this experimental study. Rats were divided into three groups: group 1 rats were given Btx-A injection only, group 2 rats were given B-vit supplementation before Btx-A injection, and group 3 rats were given Btx-A and B-vit injections together. During the experiment, compound muscle action potential (CMAP) of the gastrocnemius muscle was recorded before Btx-A injection and sequentially ten times after toxin injection. The statistical significance of the CMAP amplitude change among the groups was analyzed. All groups showed similar amplitude change between consecutive measurement points. In conclusion, combining Btx-A injection with B-vit supplement does not decrease the efficacy of the toxin.

Reduction mammaplasty using the free-nipple-graft vertical technique for severe breast hypertrophy: improved outcomes with the superior dermaglandular flap.

BACKGROUND: Management of severe mammary hypertrophy is a challenge. The limitations of most dermal pedicle techniques include insufficient breast projection with severe hypertrophy. The authors have designed a free-nipple-graft vertical technique with a superior demaglandular flap to provide acceptable breast projection and an attractive, smooth breast contour for patients with severe hypertrophy and gigantomastia who are not suitable for pedicle breast reduction techniques. METHODS: Reduction was performed for 24 patients with severe mammary hypertrophy between 2003 and 2009. This study evaluated patient age, cup size, mean distances from sternal notch to nipple and from nipple to inframammary fold, amount of resection, complications, and postoperative breast shape. RESULTS: All 24 patients were followed regularly to 1 year postoperatively. The inclusion criteria for the reported technique specified gigantomastia larger than 1,000 g per side, grade 4 breast ptosis, and increased sternal notch-to-nipple distance. The mean distance from the sternal notch to the nipple was 48.5 cm, and the mean distance from the nipple to the inframammary fold was 19.5 cm. The new nipple was positioned at a mean of 23.5 cm. The tissue excised per breast was 1,670 g. All the patients had long-lasting, pronounced nipple and adequate breast mound projection with attractive, smooth breast contours. CONCLUSION: A free-nipple graft with a superior dermaglandular flap yields a conical breast with adequate projection and fullness. Parenchyma sutures to the pectoral fascia provide long lasting results. Plastic surgeons experienced in superior pedicle breast reduction can adopt this technique easily.

A new technique in nipple reconstruction: dome technique with double pedicle.

BACKGROUND: One of the main steps for satisfactory breast reconstruction is symmetrical nipple reconstruction in an ideal position and projection. Various techniques, using cartilage, bone, fat, and even hydroxyapatite crystals, have been proposed to overcome projection loss in late term. METHOD: We present a new nipple reconstruction technique performed in 6 cases. In this technique, the nipple dome is nourished by a double pedicle and supported by lateral flaps. Nipple projection is secured with 4/0 nylon sutures, which are applied between pedicles. Skin excess is advanced to the donor areas of nipple flaps. RESULTS: All patients were discharged the day after the operation, and nipple flaps healed well. No projection loss was noted in the 8- to 12-month follow-up period. Areola shape and consistency were acceptable. CONCLUSION: Due to the presence of a double pedicle, this technique is especially helpful for patients with possible circulatory problems. Tension-free closure and rich blood supply to the nipple dome prevent loss of projection in the late term.
