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.

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.

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.

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.

Novel "all-in-one" sandwich technique for reconstruction of full-thickness defects of the lower eyelid: a case report

The current paper presents a case report of lower eyelid reconstruction after removal of a basal cell carcinoma. Our novel reconstruction method consists of translation and rotation of a paramedian forehead flap into the defect, conjunctivorhinostomy for reconstruction of the nasolacrimal duct, and placement of a sandwich ear cartilage graft that is primarily seated into the forehead flap to maintain the vertical dimension of the eyelid. This “all-in-one” technique has the advantage of one-step reconstruction, avoiding multiple surgical procedures.

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.

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.

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.

Ultrasonographic and Imaging Appearance of Peripheral Intraneural Vascular Anomalies: Report of Two Cases and Review of the Literature

The purpose of the paper is to present the ultrasonographic and imaging appearance of two cases of peripheral nerve intraneural vascular anomalies and provide a comprehensive review of the publications on this subject.The clinical presentation, ultrasonographic appearance, corresponding imaging and outcome of a case of ulnar nerve venous malformation and a case of median nerve arteriovenous malformation are presented.Literature search revealed 35 papers presenting 52 cases of vascular anomalies involving the peripheral nerves. The ultrasonographic appearance was described only in ten cases. Our review suggests that peripheral intraneural vascular anomalies are twice more frequent in women. About three quarters of them are located in the upper limb, with the median nerve involved in one third and the ulnar nerved involved in a quarter of all cases. Most of the cases are hemangiomas. Peripheral neural compartment syndromes in patients with coexisting vascular anomalies may prompt for vascular neural involvement, requiring diagnostic imaging studies. Gray-scale and Doppler ultrasound are the methods of first choice, as they provide not only direct visual proof of neural involvement but also contribute to the differential diagnosis between hemangiomas and vascular malformations.

How to deal with penile carcinoma inguinal metastases invading femoral vessels

Penile cancer accounts for 1–10% of men neoplastic diseases and 30–60% of patients have inguinal metastases at the time of diagnosis. Inguinal metastases of penile cancer with femoral vessel involvement could lead to vascular fistula and hemorrhagic shock. We present 3 consecutive patients with inguinal metastases of penile cancer complicated by infection and hemorrhage from femoral vessels invaded by the tumor. Simultaneous extra-anatomical axillo-femoral bypass graft, wide excision of tumor and groin defect reconstruction was used to achieve “tumor-free” oncologic aim and to save the lower limb. We consider the extra-anatomic axillo-femoral bypass associated with wide inguinal tumor excision and defect covering a feasible surgical solution for improving the life quality and extend life expectancy in patients with lymph node metastasis of penile cancer complicated by necrosis, infection and femoral vessel involvement.

Altered neurite morphology and cholinergic function of induced pluripotent stem cell-derived neurons from a patient with Kleefstra syndrome and autism

The aim of the present study was to establish an in vitro Kleefstra syndrome (KS) disease model using the human induced pluripotent stem cell (hiPSC) technology. Previously, an autism spectrum disorder (ASD) patient with Kleefstra syndrome (KS-ASD) carrying a deleterious premature termination codon mutation in the EHMT1 gene was identified. Patient specific hiPSCs generated from peripheral blood mononuclear cells of the KS-ASD patient were differentiated into post-mitotic cortical neurons. Lower levels of EHMT1 mRNA as well as protein expression were confirmed in these cells. Morphological analysis on neuronal cells differentiated from the KS-ASD patient-derived hiPSC clones showed significantly shorter neurites and reduced arborization compared to cells generated from healthy controls. Moreover, density of dendritic protrusions of neuronal cells derived from KS-ASD hiPSCs was lower than that of control cells. Synaptic connections and spontaneous neuronal activity measured by live cell calcium imaging could be detected after 5 weeks of differentiation, when KS-ASD cells exhibited higher sensitivity of calcium responses to acetylcholine stimulation indicating a lower nicotinic cholinergic tone at baseline condition in KS-ASD cells. In addition, gene expression profiling of differentiated neuronal cells from the KS-ASD patient revealed higher expression of proliferation-related genes and lower mRNA levels of genes involved in neuronal maturation and migration. Our data demonstrate anomalous neuronal morphology, functional activity and gene expression in KS-ASD patient-specific hiPSC-derived neuronal cultures, which offers an in vitro system that contributes to a better understanding of KS and potentially other neurodevelopmental disorders including ASD.

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.

Co-infection with Bovine Herpesvirus 4 and Histophilus somni Significantly Extends the Service Period in Dairy Cattle with Purulent Vaginal Discharge

The aim of the study was to investigate the effect of Bovine Herpesvirus 4 (BoHV-4) and Histophilus (H.) somni on fertility rate of cows in a Hungarian Holstein-Friesian dairy herd with purulent vaginal discharge (PVD). Non-pregnant cows (n = 188) with mature corpus luteum were treated with cloprostenol and 3 days later if they did not show oestrus, were examined by rectal palpation. Animals showing PVD (n = 60/31.9%/) and 14 controls with normal vaginal discharge (Score 0) were randomly selected and further examined by ultrasonography and blood samples were collected for detecting BoHV-4 DNA and transcervical guarded swabs were collected from the uterus for bacteriological examination. Although the majority of the examined animals were infected with BoHV-4 and H. somni including the control animals as well, in group of animals with PVD score 3, fewer animals became pregnant and the duration between the first treatment to pregnancy was significantly extended. Based on these clinical and comparative data, our results confirm that these two microorganisms together may impair important reproductive parameters which may cause large economic losses to dairy farms.

PAIN OUT: an international acute pain registry supporting clinicians in decision making and in quality improvement activities

RATIONALE, AIMS AND OBJECTIVES

Management of post-operative pain is unsatisfactory worldwide. An estimated 240 million patients undergo surgery each year. Forty to 60% of these patients report clinically significant pain. Discrepancy exists between availability of evidence-based medicine (EBM)-derived knowledge about management of perioperative pain and increased implementation of related practices versus lack of improvement in patient-reported outcomes (PROs). We aimed to assist health care providers to optimize perioperative pain management by developing and validating a medical registry that measures variability in care, identifies best pain management practices and assists clinicians in decision making.

METHODS

PAIN OUT was established from 2009 to 2012 with funding from the European Commission. It now continues as a self-sustaining, not-for-profit project, targeting health care professionals caring for patients undergoing surgery.

RESULTS

The growing registry includes data from 40 898 patients, 60 hospitals and 17 countries. Collaborators upload data (demographics, clinical, PROs) from patients undergoing surgery in their hospital/ward into an Internet-based portal. Two modules make use of the data: (1) online, immediate feedback and benchmarking compares PROs across sites while offline analysis permits in-depth analysis; and (2) the case-based clinical decision support system offers practice-based treatment recommendations for individual patients; it is available now as a prototype. The Electronic Knowledge Library provides succinct summaries on perioperative pain management, supporting knowledge transfer and application of EBM.

CONCLUSION

PAIN OUT, a large, growing international registry, allows use of 'real-life' data related to management of perioperative pain. Ultimately, comparative analysis through audit, feedback and benchmarking will improve quality of care.

Improved experimental burn model on rabbits

OBJECTIVE

The goal of our study was to find an easy and suitable skin burn model for rabbits, to identify the temperature and contact time to reach a deep 2nd degree burn, and to find the best wound dressing fixation method.

MATERIAL AND METHODS

We used New Zealand male rabbits as experimental models. On a pilot study, with a copper device heated to temperatures between 43-48 Celsius degrees, the burn was inflicted using contact timesof 3, 4, 5, and 7 seconds. The burn depth was evaluated histological. Twenty-four rabbits were used to evaluate four dressing fixation methods: regular dressing with retention bandages; skin stapler; collars and body resin cast.

RESULTS

A 2nd degree deep burn was obtained at 43 degrees for 4 seconds. The retention elastic bandages were removed within hours and the skin staplers were removed with teeth leaving wounds on the skin. The collars were more successful but produced superficial neck lesions. The body resin casts were the most successful.

CONCLUSIONS

The best contention method was the bpdy resin cast.

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.

The aesthetic applications of intense pulsed light using the Lumenis M-22 device

BACKGROUND

Fifteen years have passed since the first Intense Pulsed Light (IPL) devices were introduced into the market. A variety of devices that use light energy for aesthetic puposes are currently manufactured by several companies, and newer devices offering improved performance and features are periodically being introduced. Herein we present our experience with the MP-22 device (Lumenis Ltd., Yokneam, Israel) for cosmetic treatment of benign skin lesions.

PATIENTS AND METHODS

We collected patient data from all patients who received IPL and Nd:Yag laser treatments with the MP-22 over a one year period (Jan 2009-Jan 2010). The study group included 92 patients who were treated on the face, neck, trunk and hands. The main indications for treatment were lentigo and superficial vascular lesions. Patient age ranged from 16 to 72 years old, and 89 patients were female. Exclusion criteria for treatment were suspicion of skin cancer, isotretinoin treatment during the previous 6 months, and pregnancy. Satisfaction after treatment was evaluated by the patients on a scale ranging from 0 to 5, with 5 = excellent, 4 = very good, 3= good, 2= moderate improvement, 1= mild improvement and 0= no improvement.

RESULTS

Ninety-three percent of the patients were satisfied (rating 3, 4 or 5 on the above scale). Ninety-five percent of the patients had one or two treatment sessions. Of the treatments, 82 were on the face, two on the neck, four on the trunk and 13 on the dorsal aspect of the hands. Minor side effects such as erythema for longer than 24 hours and facial edema for more than one day were reported by 9 patients. Major complications such as scars, hyperpigmentation or hypopigmentation were not recorded. The fluence delivered varied from 14-18 J/cm(2).

CONCLUSION

IPL is an effective and safe method for skin treatments, namely removal of vascular and pigmented lesions.

Patients' perception of postoperative pain management: validation of the International Pain Outcomes (IPO) questionnaire

PAIN OUT is a European Commission-funded project aiming at improving postoperative pain management. It combines a registry that can be useful for quality improvement and research using treatment and patient-reported outcome measures. The core of the project is a patient questionnaire-the International Pain Outcomes questionnaire-that comprises key patient-level outcomes of postoperative pain management, including pain intensity, physical and emotional functional interference, side effects, and perceptions of care. Its psychometric quality after translation and adaptation to European patients is the subject of this validation study. The questionnaire was administered to 9,727 patients in 10 languages in 8 European countries and Israel. Construct validity was assessed using factor analysis. Discriminant validity assessment used Mann-Whitney U tests to detect mean group differences between 2 surgical disciplines. Internal consistency reliability was calculated as Cronbach's alpha. Factor analysis resulted in a 3-factor structure explaining 53.6% of variance. Cronbach's alpha at overall scale level was high (.86), and for the 3 subscales was low, moderate, or high (range, .53-.89). Significant mean group differences between general and orthopedic surgery patients confirmed discriminant validity. The psychometric quality of the International Pain Outcomes questionnaire can be regarded as satisfactory.

PERSPECTIVE

The International Pain Outcomes questionnaire provides an instrument for postoperative pain assessment and improvement of quality of care, which demonstrated good psychometric quality when translated into a variety of languages in a large European and Israeli patient population. This measure provides the basis for the first comprehensive postoperative pain registry in Europe and other countries.

Sarcoid flexor tenosynovitis as a single early manifestation of the disease

Sarcoid flexor tenosynovitis is rare. Isolated sarcoid tenosynovitis of the index finger in a young woman as an early manifestation of the disease is reported. Tenosynovectomy was performed as a therapeutic and diagnostic tool, followed by systemic corticosteroids. The patient had no signs of relapse 3 years after surgery.

Mangled lower extremity: can we trust the amputation scores?

BACKGROUND

Limb injuries represent a constant and severe problem. Several lower limb injuries are more frequent than upper limb injuries. Over time, in an attempt to quantify the severity of traumas and to establish guidelines for the decision whether to save or amputate a mangled extremity, several scoring systems have been reported. Most refer to bone fractures, soft tissue damage, vascular, nerves and tendon lesions.

MATERIALS AND METHODS

Articles dealing with mangled lower extremities published in the last 15 years were analyzed. Other inclusion criteriaincluded:articles reporting MESS, PSI, LSI, and Gustillo-Anderson scores, studies based on groups of more than 25 patients, and English language articles. We tried to determine if there was good correlation between amputation recommendations and various scores of injury, with regard to combat wounds and civilian injuries, in adult and pediatric groups.

RESULTS

Thirty-two papers fulfilled our criteria; in 17 of these, correlation between mangled extremity scores and the decision to amputate or salvage the limb was well-defined. Good correlation between MESS and amputation was found in 25% of the papers. The highest correlation was found for pediatric injuries and combined adult and pediatric combat injuries.

CONCLUSIONS

The mangled extremity is a long-lasting, unsolved problem, with much debate and a large number of protocols and scoring systems, but with no unanimously-accepted solution. Many mangled extremities are borderline cases, and the decision to amputate or to salvage a limb must be carefully assessed. With advances in the medical field over the last 15 years, more mangled lower extremities are salvaged, especially in civilian injuries.

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.

New trends in breast reconstruction

BACKGROUND

Breast reconstruction (BR) after radical mastectomy is intended to recreate symmetrical natural-appearing breasts while preserving patient safety and quality of life.

PURPOSE

To evaluate the esthetic results and the complications of various BR methods after radical mastectomy.

PATIENTS AND METHOD

Between August 2006 and March 2010, 36 women underwent BR after mastectomy in our institution. Their charts were reviewed retrospectively to evaluate the results and complications. We used immediate BR for Stage I and IIa breast carcinoma, and delayed BR for stage IIb and III breast carcinoma.

RESULTS

We performed a pedicled Transverse Rectus Abdominis Muscle flap in 13 cases, pedicled Latissimus Dorsi with silicone implant in 10 cases, free Deep Inferior Epigastric Perforator (DIEP) flap in 9 cases, and other procedures in four cases. The encountered complications were: total flap failure--one case, partial edge flap necrosis--three cases, donor area wound dehiscence--one case, seroma--one case, local infection--one case.

DISCUSSION

Trends in BR in recent years focus more on free perforator flaps, with the DIEP flap being the leader. Internal mammary vessels are most often used as recipient vessels for anasthomoses. Immediate BR when indicated has better aesthetic results. In less well-developed countries, insurance companies do not cover implant expenses and the autologous procedures remain the best option.

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.

Characterization of Francisella tularensis strains, comparing their carbon source utilization

Thirteen Francisella tularensis strains were isolated from 22 seropositive brown hares (Lepus europaeus) originating from different parts of Hungary, and further two from a patas monkey (Erythrocebus patas) and vervet monkey (Chlorocebus aethiops). The isolates were identified as F. tularensis ssp. holarctica on the basis of culture, morphological and biochemical characteristics. The identification was verified by polymerase chain reaction and the sequencing of the partial 16S rRNA gene. Utilization of carbon sources of the 15 F. tularensis strains was characterized with the Biolog system. The system was able to identify the strains already after 4 h of incubation, not only after the standard 24 h. After the analysis and comparison of the metabolic profiles of our strains with the Biolog database, it was concluded that not all carbon sources indicated in the database were utilized by our isolates. The Biolog software fails to distinguish the highly virulent F. tularensis ssp. tularensis and the moderately virulent F. tularensis ssp. holarctica but the Biolog microplates can be manually read to differentiate the two subspecies based on glycerol source utilization. As all the studied strains were unable to use glycerol, they could be identified as F. tularensis ssp. holarctica. The dendrogram based on the metabolic relationship of the strains shows that the isolates are very similar to each other, which correlates with the conservative genetic character of F. tularensis ssp. holarctica.

Electricity and fishing - a dangerous mix

BACKGROUND

The advent of fishing rods made of carbon fiber and graphite rods has greatly increased the risks of electrical injuries associated with fishing. The braided fishing lines and metal hooks put the fishermen at risk for electrical injuries.

PURPOSE

We review our burn center's experience with electrical injuries related to fishing activities during the last four years.

PATIENTS AND METHOD

We retrospectively collected data on patients with electrical burns related to fishing activities between January 2006, when our burns unit was established, and December 2009. Eight patients with electrical burns were admitted during this period of time, five who sustained the injury while fishing, due to contact of the fishing rod with overhead high-voltage cables and three who were injured during illegal fishing, using electricity to stun the fish.

RESULTS

The total burn surface area ranged from 0.5% to 70%. Three of the patients sustained fourth degree burns, while the rest had second and third degree burns. One patient underwent scapulohumeral disarticulation and an above-knee amputation. Two patients had fingers and toes amputated. Latissimus dorsi and anterolateral thigh flaps were used to cover the defects in two cases. Local flaps were employed in other two cases to cover the tissue defects. Two patients died.

CONCLUSION

Fishing-related burns and illegal fishing can lead to serious injuries and death.

Diagnosis and characterization of cutaneous tumors using combined ultrasonographic procedures (conventional and high resolution ultrasonography)

High resolution ultrasonography, using 20-50 MHz transducers, is a novel diagnostic procedure for the investigation of the skin and its specific conditions. Conventional ultrasonongraphy allows the identification of palpable pigmentary lesions without being able to establish the histologic type of the lesions. The method assesses the degree of tumoral penetration and the presence, type and intensity of circulation at that level. High resolution ultrasonography allows the identification of macular and nodular pigmentary lesions located up to 1.5 cm in depth. There is a correlation between the high resolution ultrasonographic aspect and the Breslow index used for melanoma stadialization. This correlation is limited in the presence of perilesional inflammatory infiltrate. The imaging examination is a valuable assessment method of the skin and its specific conditions. High frequency cutaneous ultrasonography has an important contribution in the screening of pigmentary lesions at risk.

Tularemia of European Brown Hare (Lepus europaeus)

The European brown hare ( Lepus europaeus) plays an important role in the ecology of tularemia, and it may serve as a significant source of human infection. The aim of the present study was to examine the lesions induced by Francisella tularensis in 50 cases of naturally infected seropositive European brown hares. Gross pathological examination revealed scant to numerous grayish-white foci with diameters of 0.1 to 1.0 cm in single organs (24 cases) or multiple organs (20 cases) in 44 of 50 cases (88%). These lesions proved to be areas of granulomatous inflammation, frequently encompassing necrosis. F tularensis antigen was detected with immunohistochemistry in 46 of 50 cases (92%), whereas F tularensis ssp holarctica was isolated by culture and identified by polymerase chain reaction from 35 of 50 cases (70%). Infection by the respiratory route is suggested by the presence of the tissue lesions in thoracic organs of 44 of 50 cases (88%). These results emphasize the importance of the European brown hare as a reservoir of tularemia.

Gastroduodenal artery pseudoaneurysm ruptured in the common bile duct

A pseudoaneurysm of the gastroduodenal artery (GDA) is the rarest splanchnic artery aneurysm, comprising fewer than 10% of these lesions. Bleeding into the gastrointestinal tract is the most rapidly fatal complication of an arterial visceral pseudoaneurysm, affecting 4-10% of patients. We present an unusual case of a GDA pseudoaneurysm that ruptured in the common bile duct, and that was successfully treated by partial resection and hepatic artery reconstruction. The postoperative evolution was favourable and the CT performed six months later disclosed the absence of a vascular tumour.

Different models of training and certification in plastic surgery

A varying period of training followed by examinations is the usual way to become a specialist in one of the many fields of Medicine. Plastic Surgery is one of the surgical fields that require good technical and cognitive skills. The best way to train and evaluate a candidate is hard to judge. The model of training and board examination varies, every country having its own method. This is a descriptive report presenting the ways of training residents in Plastic Surgery and then examining them in Romania, Israel, U.S.A., Germany and the Netherlands. Specific points regarding the structure and the format are addressed for all models and also for factors that might influence the objectivity of the examination. The authors bring their thoughts on these issues.

Effect of hyperbaric oxygen on survival of composite grafts in rats

Most treatment with hyperbaric oxygen (HBO) in plastic surgery is for wounds, burns, crush injuries, and infections. We aimed to find out if HBO increases the survival of composite grafts in rats. Twenty Sprague-Dawley rats were randomly assigned to two equal groups (treatment and control). A template 30 x 30 mm was placed on the skin and a composite graft taken from the upper back was harvested and then resutured to the fascia in situ. The treated group was placed in a hyperbaric chamber set at 202 kPa and 100% oxygen for 90 minutes daily for two weeks. Control animals were given no treatment. After death the mean surviving internal surface area of the graft was 372.5 (117.9) mm2 in the control group and 561.3 (85.7) mm2 in the experimental group (p=0.001). Treatment with HBO improved the surviving area of composite grafts in rats, and the beneficial effect was prominent only on the inner surface of the graft.

Simultaneous extra-anatomic bypass and abdominal "flag flap" for lower limb salvage in a patient with severe post-bypass anastomotic groin infection

The incidence of prosthetic graft infection after bypass surgery ranges from 0.2 to 5%, depending on location, co-morbid diseases and host defense mechanisms. In spite of surgical treatment, the amputation rate can be up to 67%. Herein, we present our treatment strategy for a patient with severe Methicillin Resistant Staphylococcus Aureus infection and pseudo-aneurysm after a femoropopliteal bypass with a prosthetic graft. An extra-anatomic bypass without touching the previously operated groin area (aseptic time) was done at the beginning. Radical debridement (septic time) and simultaneous abdominal "flag flap" were performed in the same surgical procedure to save the lower limb.
