Bilateral Hand Metastases From a Pleomorphic/Dedifferentiated Leiomyosarcoma: A Case Report.

ABSTRACT: Leiomyosarcomas of the lower extremity are heterogeneous tumors with high recurrence and metastasizing rates, which, rarely, can suffer a dedifferentiation process, making them extremely aggressive and unpredictable. We report the case of a 72-year-old female patient who presented the clinical and histopathological features of a rare leiomyosarcoma of the foot that was completely excised, but because of the interruption of adjuvant oncological treatment and lack of compliance for the follow-up, the patient suffered a dedifferentiation process and the tumor metastasized in the fingers-an unprecedented site for this type. The present case proves the fact that there is still a lot we do not know about the behavior of this disease, and there is always room to learn. Also, through this report, we are emphasizing a frequently encountered and never-ending problem in our country-that of difficult and resource-consuming cases derived from disconsidering medical advice by noncompliant patients when faced with a malignant diagnosis, making all attempts to offer them a better quality of life futile.

Breast Reconstruction with Non-Abdominal Autologous Tissue.

The progresses in surgical field are amazing regarding the possibilities of soft tissue reconstruction. Techniques of breast reconstruction have been evolved since the last 40 years. There was a trend from pedicled flaps toward microsurgical free flaps. In the English literature have been reported several types of free flaps for BR. Although DIEP is the workhorse for the reconstruction, there are patients that do not have enough abdominal tissue to use. In those cases, other donor area such as buttock, thigh, lumbar area has been reported. The present article describes the choices for BR with non-abdominal autologous tissue.

The influence of drugs on peripheral nerve regeneration.

Currently, there are no established adjuvant drugs for the acceleration of peripheral nerve regeneration. In this paper, we reviewed the literature from the last 10 years and described the drugs proved to accelerate the functional and histological regeneration of the peripheral nerves, either after trauma or in neuropathy experimental models. The vast majority of the studies were experimental with very few small clinical studies, which indicates the need for prospective randomized studies to identify the best drugs to use as adjuvants for nerve regeneration.

Three Simultaneous Free Flaps to Reconstruct a Complex Frozen Neck and a Large Hypopharyngeal Fistula.

Frozen neck and hypopharyngeal fistula are sometimes present after tumor ablation of the larynx, multiple local surgeries with scar tissue, and radiotherapy and chemotherapy. This multiorgan involvement requires 1 or even 2 flaps. We present a 63-year-old heavy smoker with frozen neck tissue and simultaneous large hypopharyngeal fistula and neck defect. After careful preoperative planning, he was successfully treated with 3 simultaneous free flaps: 2 anterolateral thigh flap (ALT) and 1 lateral arm flap (LAF). One ALT was used as a patch to restore the hypopharynx continuity. A second ALT was used to cover the anterior neck defect and the LAF flap was used to reconstruct the submandibular area. The flaps survived and the patient had a 5 mm proximal fistula which was sutured, and he was able to eat per mouth. By combining multiple free flaps, we were able to restore the function of the hypopharynx and to cover the esthetic units of the neck by avoiding the "turkey neck" appearance.

Strategies for Complex Scalp Reconstruction in Patients With Poor Recipient Vessels.

Complex scalp defects with poor recipient vessels represent a challenge for plastic surgeons. In these cases, free flaps are the last resort for solving the problem. The authors present 5 difficult cases with complex large scalp and calvarium defects with unsuitable small recipient vessels for anastomoses. For these cases, the lesser saphenous vein was harvested and used as an interposition graft between the external carotid artery, the jugular vein, and the flap. Latissimus Dorsi, Anterolateral Thigh, and serratus anterior were the flaps used for reconstruction. Cranioplasty was simultaneously performed in 4 cases. The scalp defects varied from 83 to 288 cm. All flaps survived. In 1 case (extended Latissimus Dorsi) there was local infection and wound dehiscence with marginal flap necrosis that required flap readvancement. In conclusion, end-to-end anastomosis to the external carotid artery offers strong outflow through the vein graft and flap. A large vein graft allows good outflow and is more resistant to the pressure of the skin envelope. Anastomosis to large neck vessels (internal or external jugular) facilitates drainage since there is also an aspiration effect due to the venous flow circulation through it.

Chimeric Lateral Arm Free Flap to Treat Pharyngocutaneous Fistula After Total Laryngectomy.

Pharyngocutaneous fistula is a major complication after total laryngectomy, leading to a severe adverse impact for the patient and social activity. The reported incidence ranges from 9% to 25% in the last decade. In this paper, the authors present our experience using chimeric lateral arm free flap for reconstruction of the pharyngo-esophageal segment. Eight patients with pharyngocutaneous fistula were treated with this technique. The flap has 2 skin islands, each one supplied by a perforator coming from the main pedicle. One skin island is used as a patch for pharynx closure and the other is used for anterior soft tissue coverage. The follow-up period ranged from 8 months to 3 years. All flaps survived. There was 1 small fistula that was sutured. External skin wound dehiscence was present in 1 case and it was secondary closed by itself. All patients were able to eat by mouth and there were no signs of stricture. The authors preferred this type of flap because both defects are simultaneously closed and each skin paddle is supplied by a perforator coming from the main pedicle. It has a better color match than other free flaps. The skin island is thin and remains thin even after the patients gain weight.

Simultaneous Total Esophagectomy and Anterior Mediastinal Tracheostomy for Recurrent Laryngeal Cancer Extended to the Superior Mediastinum.

Recurrent laryngeal cancer has an incidence of 25-50% and a 23-35% fiveyear survival rate. Surgery is the best treatment in order to control local recurrence. Herein, we present our surgical strategy for a patient with a history of modified radical laryngectomy for laryngeal cancer and with recurrent tumor at the cervical tracheostomy site extended to the thoracic trachea and esophagus. The wide resection included the sternal manubrium, the upper thoracic trachea, the entire esophagus and the upper mediastinal lymph nodes. The reconstruction included anterior mediastinal tracheostomy and esophagoplasty with pedicled colonic graft simultaneously with pectoralis major flap for covering the sternal defect.

Diffuse angiomatosis of the breast--sonographic appearance.

Angiomatosis or diffuse hemangioma is a very rare benign vascular tumor, consisting of blood and lymphatic channels growing diffusely in the breast parenchyma. We report a case of diffuse breast angiomatosis in a 34-year-old woman with pubertal anisomastia. Ultrasound raised the suspicion of vascular tumor, by showing large cystic spaces separated by septae with moderate blood flow, similar to those found in cystic lymphangioma. We discuss the imaging (mammography, ultrasound, and MRI) and pathologic findings, with a brief review of the literature.

Predictors for anaemia, blood transfusion and outcome in plastic surgery patients.

OBJECTIVE: In patients undergoing plastic surgery, to identify specific risk factors for anaemia and use of blood products, and assess their impact on patient outcome. METHOD: For this retrospective study, data were analysed from patients who attended the Plastic Surgery Department at our hospital over a three-year period (2018 to 2020). Adult patients who presented with traumatic injuries, oncologic patients who underwent reconstructive procedures, and patients with soft tissue infections (STIs) who required plastic surgery for tissue coverage were included. Demographic and injury data, hospital admission characteristics, surgical procedures, laboratory test results, transfusion events, and in-hospital complications were extracted from patient records. RESULTS: Of the 350 patients included in the study, 228 (65%) presented with trauma, 76 (22%) underwent reconstructive surgery for cancers and 46 (13%) had STIs. In total, 175 (50%) patients developed anaemia, and 37 (11%) received blood transfusions; these were 20 (54%), 5 (14%), and 12 (32%) patients in the trauma, cancer and STI groups, respectively. Associated comorbidities and upper and lower limb surgery were the most significant risk factors for anaemia, while the number of surgeries and NSTIs were identified as risk factors for blood transfusions. Direct wound closure was consistently a protective factor for both anaemia and blood transfusions. Blood transfusions were independently associated with a high risk of sepsis, wound complications, and prolonged hospital stay. CONCLUSION: While transfusions are necessary and even lifesaving in surgical patients, blood is a finite resource and its use may negatively impact patient outcome. Therefore, ongoing research must focus on providing safe and restrictive clinical practices while developing sustainable and accessible alternatives.

Blood transfusions in non-major burns patients.

BACKGROUND: Blood transfusions are essential to treating anaemia of burn injuries. It has recently been observed that patients with non-major burns < 20%TBSA may also develop anaemia requiring transfusion of blood products. Due to the morbidity and mortality rate associated with blood transfusions better understanding of risk factors may guide clinical practices to improve patient care. OBJECTIVE: To determine risk factors for transfusion of blood products in patients with non-major burn injuries and assess transfusion practices to establish impact on patient outcome. METHOD: Our study included 182 adult patients with non-major burn injuries, < 20%TBSA admitted over a 3-year period at the Department of Plastic Surgery and Burns Unit of the Emergency County Hospital Cluj-Napoca. We analysed patient and injury characteristics: age, gender, %TBSA burn, %FT burn, burn site, mechanism of injury, inhalation injury, Hb lab determinations throughout admission and surgical management. Charlson comorbidities index has been determined based on cardiovascular, neurological, gastrointestinal and renal comorbidities as well as diabetes mellitus. We selected blood transfusions, wound infections and length of hospital stay as outcome for our analysis. RESULTS: 37.9% of patients included in our study developed anaemia throughout admission and 7.7% underwent blood transfusions. Mean Hb levels triggering blood transfusions have been recorded at 7.4 (IQR=8.8-9.9) g/dL. Patients who received transfusions were older, presented with higher %TBSA and associated a higher comorbidity index. They also tended to develop coagulopathy and underwent more surgical procedures to achieve wound closure. In transfused patients who associate comorbidities we observed a higher rate of wound infections and longer hospital stay. CONCLUSIONS: Patient related comorbidities correlate with higher transfusion rates in non-major burn injuries. Due to the risk associated with the use of blood products decision to transfuse should adhere to current guideline practices and be tailored to specific patient requirements.

Combined distal median nerve block and local anesthesia with lidocaine:epinephrine for carpal tunnel release.

Aim: Evaluating patient comfort during full awake local anesthesia in carpal tunnel release surgery, without tourniquet use, by using epinephrine to obtain a completely dry surgical field. Methods: We included into the study 41 patients who underwent carpal tunnel syndrome surgery under full awake combined anesthesia, using a 9-point questionnaire. Pain and anxiety in all patients were evaluated through a Wang-Baker 0-5 scale. The injection solution consisted of 0.1cc of epinephrine and 10cc of 1% lidocaine (1:100.000); 5cc were used for local cutaneous anesthesia, and 5cc were used for distal median nerve block. All patients underwent a classic, open carpal tunnel release. Results: Anxiety scores during anesthesia and the post-operative period did not show a statistically significant difference (p > 0.01), with keeping their levels at low perception scores (average score of 1.68 ± 0.38 CI 95%, with a modal value of 2, compared to an average of 0.78 ± 0.29 CI 95% with a modal value of 0). Similar results were obtained for pain scores during anesthesia (1.73 ± 0.48 CI 95% with a most frequent modal score of 1). Our results also showed that the effects of combined anesthesia in carpal tunnel release surgery persisted well into the 6-hour post-operative moment, pain scores remaining low, statistically significant similar to recorded values during the anesthesia moment (p > 0.01), at an average of 2.29 ± 0.5 CI 95% with a modal value of 1. No serious complications were recorded. Conclusion: Combined distal median nerve block and local anesthesia with epinephrine:lidocaine provides a comfortable option for patients, with minimal risks of complications.

Anomalies of thoracic outlet in human fetuses: anatomical study.

BACKGROUND: Thoracic outlet syndrome (TOS) identifies the clinical condition determined by the mechanical compression and entrapment of the subclavian vessels and the brachial plexus cords within the space delineated by the scalene muscles, the clavicle, and the first rib. To date, there are no concluding explanations concerning the real causes of the appearance of TOS in children. This is the first study to investigate the existence, frequency, and type of thoracic outlet anomalies in the prenatal stage (human fetuses). METHODS: Eighty cervical dissections (40 consecutive spontaneously aborted human fetuses) were performed, and the musculoskeletal, vascular, and nervous elements that pass through the thoraco-cervico-axillary region were investigated. RESULTS: Overall, anatomical anomalies of the thoraco-cervico-axillary region were found in 60% of the 80 cervical dissections. Nine (22.5%) of the 40 fetuses had normal bilateral anatomy. In 6.3%, the scalene hiatus had an oval shape due to the common costal insertion of the anterior and middle scalene muscles. Fibromuscular bands were found in 15% of the fetuses. Hypertrophy of the anterior scalene muscle was seen in 12.5% of the dissections. In 28.7% of the cervical dissections, hypertrophy of the C7 transversal process was noted, bilateral in seven cases. There was one case of a "C-shaped" clavicle anomaly. The absence of the internal mammary artery was noted in one case. CONCLUSION: This study shows that the presence of TOS anomalies in fetuses is not a rare occurrence, emphasizing a pathological cervical background which can be harmful in situations of cervical trauma or inflammatory processes. Having knowledge of the types of anomalies which can lead to TOS is important for performing a complete surgical correction and avoiding the high failure rate of recurrent TOS.

How to perform breast augmentation safely for a pectus excavatum patient.

BACKGROUND: Pectus excavatum is the most common chest wall deformity. Women with pectus excavatum may have associated hypoplastic breasts and often desire breast augmentation. This report describes how to perform breast augmentation safely for a pectus excavatum patient. METHODS: In the past 5 years, the authors have treated 11 women with hypoplastic breasts and pectus excavatum. Their ages have varied from 21 to 39 years. The women generally were healthy without cardiovascular function impairment. Four of the women had breast asymmetry, with a smaller right breast. It was decided to use wide silicone implants to augment the breast and to camouflage the chest wall deformity. The implants were placed under the pectoralis major muscle in all cases. RESULTS: The follow-up period varied from 10 months to 4.5 years. No acute or late complications related to the breast augmentation were encountered. All the patients were satisfied with the result, and none desired further surgical treatment for pectus excavatum. For two patients, a small depression in the upper part of the breast was persistent after surgery due to insufficient implant coverage. CONCLUSION: Most women with pectus excavatum desire to have the deformity corrected with minimal or no scarring. The chest is known to be an area prone to hypertrophic or keloid scars. The reported approach is simple and safe, easily camouflaging the deformity. It is a short procedure that results in high satisfaction.

Simultaneous femoro-popliteal artery bypass and foot free flap for lower limb salvage: a 13-year follow-up.

Critical limb ischemia (CLI) associated with lower extremity complex wounds is challenging for vascular and plastic surgeons. Despite a high risk of perioperative morbidity, complex reconstructive surgery in these patients is an alternative to primary major limb amputation. We present a patient with CLI and a complex foot wound treated with simultaneous femoro-popliteal arterial bypass and free flap for lower limb salvage. The 13-year follow-up showed good functional results.

The role of the pedicle omental flap in ruptured abdominal aortic aneurysm: a case report and literature review.

A ruptured infrarenal abdominal aortic aneurysm (rAAA) is associated with an in-hospital mortality rate of 40% and an overall mortality rate of 60-80%. Open surgical repair for rAAA remains the principal method of treatment when endovascular repair is not available. Graft infection occurs in 1-4% of patients at 5 years, with a high incidence following emergency treatment. Other graft-related complications include pseudoaneurysm, graft occlusion and aorto-enteric fistula. This case report describes a 66-year-old male patient that was admitted to hospital complaining of intense abdominal pain, low blood pressure and tachycardia. He was diagnosed with a rAAA and treated using segmental resection of the abdominal aorta followed by reconstruction with a synthetic Dacron prosthesis. A pedicle omental flap was wrapped around the prosthetic graft and it was also used to fill the retroperitoneal cavity in order to reduce the risk of graft-related complications. Computed tomography angiography after 6 months showed good integration of the aortic prosthetic graft and the viability of the omental flap. In our opinion, vascular surgeons should consider the pedicle omental flap when they perform open surgical repair for rAAA in order to reduce the incidence of graft-related complications.

A rare case of schwannomatosis of the extremities.

A schwannoma is a benign tumor that arises from the myelin-producing Schwann cells that surround nerves. We herein report a case involving a 55-year-old man who first presented to our clinic with a schwannoma of the posterior tibial nerve and 5 years later with a schwannoma of the ulnar nerve. This is the first report of schwannomatosis of the ulnar and posterior tibial nerves.

Long-term results after Ilizarov treatment for severe high-energy injuries of the elbow.

BACKGROUND: Clinical aspects, such as the long-term results after circular external fixation and functional rehabilitation after high-energy injuries of the elbow joint, have not received sufficient attention in the literature. METHODS: Fourteen patients with high-energy elbow injuries were treated in our hospital over the last 15 years with a circular external fixation frame. The mechanism of injury was blast in eight patients, gunshot wounds in two, motor vehicle crash in two, and fall from height in two. Twelve patients had high-energy open periarticular fractures, nine had Gustillo-Anderson 3B fractures, and three had Gustillo-Anderson 3C fractures. Two patients suffered from closed high-energy periarticular elbow injuries. Seven patients had associated peripheral neurologic injuries and three had vascular injuries. Average Ilizarov fixation time was 20 weeks (range, 6-47 weeks). RESULTS: The follow-up period varied from 1.5 years to 11 years. The average arc of elbow flexion was 110.4 degrees and extension was 19.6 degrees. The average arc of forearm rotation was of 63.5 degrees for pronation (range, 5-90 degrees) and 63.2 degrees for supination (range, 5-90 degrees). The average Mayo Elbow Performance Index score was 84 points (range, 60-100) and the average Khalfayan functional score was 83.4 (range, 68.7-100). CONCLUSION: Long-term follow-up proved that the hinged Ilizarov/hybrid frame represents a useful instrument to provide stabilization of the elbow joint while facilitating early movements and physiotherapy. The main indication is patients who suffered from open high-energy contaminated fractures with extensive soft-tissue damage (e.g., blast, war injuries) and combined bone and ligaments injuries.

Intense pulsed light for skin rejuvenation, hair removal, and vascular lesions: a patient satisfaction study and review of the literature.

There are very few studies in the English literature that evaluate the patient satisfaction after treatment using intense pulsed light (IPL) and there is no reported study comparing the results of the three major IPL applications: rejuvenation, hair removal, and treatment of small vascular lesions. This study was designed to compare results after IPL treatment for skin rejuvenation, hair removal, and vascular lesions. Three groups of 30 consecutive patients having skin rejuvenation, hair removal, and small vascular lesions were selected and treated with the same IPL system. The evaluation was performed 1 year after the last treatment for the following parameters: age, sex, skin type, satisfaction, willingness to continue the treatment, willingness to recommend the treatment, and complications. Most of the minor complications occurred in the rejuvenation group (86.6%). No complications were recorded for 67% of patients having hair removal and for 75% having vascular lesion treatment. There was no significant difference in the level of satisfaction between the 3 groups (Kruskal Wallis test; P = 0.257). No difference regarding satisfaction was recorded in this study, but complications were more frequently encountered after rejuvenation. The findings of this study are useful when discussing IPL treatments with patients considering IPL procedures.

Primary B lymphoma tumor of the ulnar nerve. Case report.

Primary lymphoma of a peripheral nerve is a very rare condition with only a few cases reported in the medical literature. Primary lymphoma of a peripheral nerve in the upper extremity was reported in only four cases in the English and French literature. We present a case of a 54-year-old man, in good health, without other medical conditions, who came to our unit complaining of paraesthesia in the ulnar territory of the hand. MRI investigation showed a mass situated in the ulnar nerve sheaths, in the lower third of the arm. Surgical exploration and excision were performed. Morphopathological results revealed a very uncommon tumor, a large B cell diffuse non-Hodgkin lymphoma, the second primary ulnar nerve lymphoma presented in the literature. Early diagnosis and a better understanding of the pathogenesis of these tumors may change medical and surgical strategies, with further enhancement of survival rates.

Topical Oxandrolone Reduces Ear Hypertrophic Scar Formation in Rabbits.

BACKGROUND: Wound healing is a complex process. Despite extensive studies, hypertrophic and keloid scars still occur, and can be functionally and cosmetically problematic. In an attempt to prevent hypertrophic scar formation, the effects of topical oxandrolone, using hyaluronic acid as a biomaterial, were studied on ear wounds in rabbits. METHODS: Deep second-degree burns were inflicted on each ear in 10 New Zealand rabbits. On the left ears, considered the control side, hyaluronic acid gel was applied, whereas on the right ears, the study side, a combination of oxandrolone and hyaluronic acid was applied. Dressings were changed every 2 days for 2 weeks. At week 10, biopsy specimens from the postburn scars were harvested for histologic and immunohistochemical examinations. RESULTS: Fourteen wounds were studied, half on the control side and half on the study side. Six hypertrophic scars were encountered on the control side and only one scar was encountered on the study side. In addition, an increased degree of inflammation, an increased amount of collagen and fibroblast cellularity, increased vascularization, and increased myofibroblast activity were observed on the control side. CONCLUSION: Topical administration of oxandrolone using hyaluronic acid as a biomaterial led to better healing and prevented hypertrophic scar formation.
