RESUMO

Elastofibroma is a benign and slow-growing soft tissue tumor that classically presents as an ill-defined solitary mass at the inferior pole of the scapula in the fifth and sixth decades of life for women. This tumor can be rarely seen in childhood, but it has not been reported in the infantile age group to date. To our knowledge, this case represents the first report of elastofibroma in the infantile age group. The aim of this report is to present a paravertebral elastofibroma in a 14-month-old patient and discuss the clinical features and treatment modalities.

RESUMO

INTRODUCTION: Although cartilage grafts are frequently used for structural integrity and volume restoration, one of the main concerns dealing with cartilage grafting is gradual volume loss and unpredictable viability rates of cartilage grafts. Platelet-rich plasma (PRP) is a well known platelet concentrate reported to enhance cartilage repair and stimulates chondrocyte proliferation and matrix biosynthesis. The purpose of the current study was to investigate the effect of subcutaneous PRP injection on improving the viability of cartilage grafts. MATERIALS AND METHODS: Six circular cartilage grafts were obtained from auricular cartilages of 6 New Zealand white rabbits. Cartilage grafts were prepared in 3 forms: block, crushed, and crushed/wrapped with Surgicel (Surgical, Ethicon, Somerville, NJ). Grafts were placed to 6 dorsal subcutaneous pockets and pockets were closed. Autologous PRP was prepared and injected subcutaneously into the pockets of experiment groups. At the end of 8 weeks, cartilage grafts were removed. Cartilage mass reduction rates were measured. Resorption rates of cartilage grafts and formation of fibroelastic and bone tissue were microscopically evaluated. RESULTS: All of the cartilage grafts lost significant weight. Viability scores of block cartilages were higher than crushed cartilages. Although less weight loss rates and higher histopathologic scores were obtained in subcutaneously PRP injected cartilage graft groups, these results were not statistically significant. CONCLUSIONS: Although our study gives a new insight about increasing the viability of cartilage grafts, the subcutaneous PRP injection did not result in improving the viability of cartilage grafts in this experimental design.

RESUMO

Gold weight implantation is generally considered a safe procedure for the treatment of paralytic lagophthalmos. The most frequently seen complications are extrusion, malpositioning, and migration of the implant. To decrease the rate of these complications, several modifications were defined in the composition and the shape of the implant as well as the surgical technique itself. Despite these precautions, implant revision rates are still as high as 8% to 14%. Nowadays, implant-covering or implant-wrapping procedures are becoming more popular to avoid implant-related problems. However, there is limited information in the literature regarding the management of these complications. In this study, we aimed to present the treatment of migration and extrusion of the gold weight implant in a patient with Moebius syndrome by wrapping the implant with autogenous fascia lata graft.

RESUMO

BACKGROUND: Combination treatments of botulinum toxin type-A and other rejuvenation agents or instruments are gradually becoming more popular. After observing a high incidence of therapy failure following simultaneous applications of botulinum toxin type-A and platelet-rich plasma mesotherapy, we aimed to investigate whether PRP has an inhibitory effect on botulinum toxin type-A. METHODS: Twenty-four New Zealand white rabbits were divided into 4 groups, and the anterior auricular muscle and overlying skin were used for injections. Groups I and II both received onabotulinumtoxinA intramuscular injections. In addition, autologous platelet-rich plasma mesotherapy was performed in Group I while Group II received saline mesotherapy. Group III was designed as the in vitro mixture group in which onabotulinumtoxinA and platelet-rich plasma were mixed and then administered intramuscularly. Group IV received saline within the mixture instead of platelet-rich plasma. The contralateral ears of all the rabbits served as control and were only treated with onabotulinumtoxinA. Visual evaluation of ear positions and electroneuromyographic studies were done prior to all procedures and at day 14. Anterior auricular muscles were harvested at day 14 and were evaluated with quantitative real-time PCR. RESULTS: Visual and electroneuromyographic studies revealed less onabotulinumtoxinA activity in Groups I and III. When platelet-rich plasma was administered through skin mesotherapy, onabotulinumtoxinA activity failure was more severe in comparison with direct contact. No significant difference in SNAP-25 mRNA expression through quantitative real-time PCR was observed between groups. CONCLUSION: Although we could not explain the exact mechanism underlying this interaction, platelet-rich plasma applications result in less onabotulinumtoxinA muscle paralysis activity.

RESUMO

BACKGROUND: Disulfiram implantation is a widely used treatment alternative for alcohol abuse, yet reports on the surgical aspect of disulfiram implantation with respect to patient and drug-related treatment efficacy and wound complications are very limited. We present our clinical experiences with disulfiram implantation and discuss the surgical outcomes obtained with different anatomical planes for implantation. METHODS: Medical records of all patients referred to our clinic from the psychiatry department between 2007 and 2013 for disulfiram implantation were retrospectively analyzed. Implantation was carried out using 10 sterile Disulfiram tablets (WZF Polfa S.A.), each tablet containing 100 mg of disulfiram. The procedure was carried out by implanting the tablets randomly in either a subcutaneous or an intramuscular plane. The location and the plane of implantation and the complications were recorded for each patient and compared to determine the differences in the outcomes. RESULTS: A total of 32 implantation procedures were evaluated for this study. Twenty-five implants were placed in the intramuscular plane (78.2%), while seven implants were placed subcutaneously (21.8%). Exposure was encountered in three of the seven subcutaneous implants (42.9%), while no exposure was seen with the intramuscular implants. Incomplete absorption of the tablets was encountered in one patient with a previous subcutaneous implant who presented 1 year later for re-implantation as part of the continuation of therapy. CONCLUSIONS: To overcome the issue of treatment continuation in the case of disulfiram therapy, which may be ceased due to frequently encountered wound complications, we believe that implantation in the subscapular intramuscular plane allows both uneventful healing and an out-of-reach implant location.

RESUMO

BACKGROUND: Minimally invasive procedures are becoming increasingly popular because they require minimal downtime and are effective for achieving a more youthful appearance. The choice of needle for minimally invasive procedures can be a major factor in the patient's comfort level, which in turn affects the physician's comfort level. OBJECTIVES: In this comparative study, the authors assessed levels of pain and bruising after participants were injected with 30-gauge or 33-gauge (G) microneedles, which are commonly used for minimally invasive injection procedures. METHODS: Twenty healthy volunteers were recruited for this prospective study. Eight injection points (4 on each side of the face) were determined for each patient. All participants received injections of saline with both microneedles in a randomized, blinded fashion. Levels of pain and bruising were assessed and analyzed for significance. RESULTS: The highest level of pain was in the malar region, and the lowest level was in the glabella. Although all pain scores were lower for the 33-G microneedle, the difference was significant only for the forehead. Because most minimally invasive procedures require multiple injections during the same sitting, the overall procedure was evaluated as well. Assessment of the multiple-injection process demonstrated a significant difference in pain level, favoring the 33-G needle. Although the difference in bruising was not statistically significant between the 2 needles, the degree of bruising was lower with the 33-G needle. CONCLUSIONS: For procedures that involve multiple injections to the face (such as mesotherapy and injection of botulinum toxin A), thinner needles result in less pain, making the overall experience more comfortable for the patient and the physician. LEVEL OF EVIDENCE: 3.

RESUMO

Although fat grafts are considered the ideal soft-tissue fillers, the main concern dealing with this technique is not being able to predict long-term graft survival due to high absorption rates. The purpose of this study was to investigate the angiogenic effects of preconditioning the recipient area with micro-needling and to determine its overall impact on fat graft survival. The study consisted of a sham, control and study group. The source of fat was the Wistar albino rat inguinal fat pad while the recipient area was a dorsal subcutaneous pouch. The dorsal area was preconditioned with standard technique micro-needling 1-week prior to fat graft transfer in the study group while the control group did not undergo micro-needling. At the end of 15 weeks, morphological, biochemical, histological and immunohistochemical evaluation was carried out. Fat grafts in the study group had better integrity and a higher level of vascularity compared to the control group. Volume analysis demonstrated higher graft survival in the study group in comparison to the control group. Histomorphometric and immunohistochemical evaluation showed better graft integrity and uniform adipocytes, less fibrosis, less vacuolisation and inflammation and better vascularisation in the study group. Although higher triglyceride concentrations were measured for the study group, the difference between the two groups was statistically insignificant. In conclusion, fat grafting performed in an area preconditioned with micro-needling results in higher graft volume, better integrity and vascularisation and an overall higher graft survival rate.

RESUMO

INTRODUCTION: Botulinum toxin type A (BTX-A) is currently used in temporal brow lifting. Reducing the activity of the superolateral portion of orbicularis oculi muscle causes lateral brow elevation. The objective of this study was to determine the quantitative brow elevation after paralysis of the superolateral portion of orbicularis oculi muscle. MATERIAL AND METHODS: This study includes 10 female patients. Six units of BTX-A were injected into the superolateral portion of the orbicularis oculi in a serial manner into 3 points, below the lateral half of the brow at each side. Bilateral measurements were obtained by using calipers, immediately before and 2 weeks after the treatment. The medial canthus to the medial brow margin (AB), the lateral brow margin to the lateral canthus (CD), the medial brow margin to the lateral brow margin (BC), the brow apex to upper lid margin at the level of the lateral limbus (EF), the brow apex to the medial brow margin (EB), the brow apex to the lateral brow margin (EC), and upper eyelid margin to lower eyelid margin at the level of the pupil (GH), were measured. RESULTS: There were no statistically significant differences found between pretreatment and posttreatment left and right measurements. There were statistically significant increases in CD, EF, and GH measurements, which are point out brow elevation. There were no statistically significant differences found in other measurements. CONCLUSIONS: Same doses of BTX-A application did not disrupt symmetry. Applications of 6U BTX-A to the superolateral portion of orbicularis oculi provide brow elevation and increased interpalbebral distance and upper eyelid distance. Our study has confirmed that BTX-A treatment of superolateral portion of the orbicularis oculi muscle produces quantitative temporal brow elevation.

RESUMO

BACKGROUND: Although many studies have shown that breast reduction surgery is effective in reducing neck, back, and lumbar pain, most of these studies are subjective evaluations that usually provide data through pain scales. This study was undertaken to objectively evaluate the radiologic effects of breast reduction on the vertebral column. METHODS: Thirty patients who underwent breast reduction surgery were included in the study. A lateral thoracolumbar radiograph was taken before and 3 months after surgery for each patient. The thoracic kyphosis, lumbar lordosis, and sacral inclination angles were measured for each radiograph. The impact of breast reduction surgery on posture was evaluated according to the comparison of these angles before and after surgery. The effect of age, body mass index, and the total amount of removed tissue was also taken into account, and the relationship between these parameters and their effects on the change in preoperative and postoperative angle measurements were evaluated. RESULTS: There was a significant decrease in all 3 angles after breast reduction surgery. A significant correlation was determined between body mass index and the total amount of removed tissue on the change in angle measurements, whereas a definite relationship was not observed between the angles and the patient's age. CONCLUSIONS: This study has shown the objective impact that breast reduction surgery has on the vertebral column. Although the symptomatic relief of breast reduction surgery on the musculoskeletal system is widely accepted, the objective assessment of this relief will be beneficial in persuading health insurance companies and those who think of this surgery as a purely aesthetic procedure.
