ABSTRACT

BACKGROUND: Uterine smooth muscle tumor of uncertain malignant potential (STUMP) is rare tumor, and regarded as sub-classification in uterine smooth muscle tumors between benign and malignant criteria. In this study, we evaluated characteristics of cases with STUMP diagnosis in a 10-year period. METHODS: We retrospectively evaluated medical records of patients with histopathological STUMP diagnosis in Istanbul Training and Research Hospital, a tertiary center. We analyzed preoperative demographic, clinical features and postoperative follow-up. Preoperative sonographic data were re-evaluated. RESULTS: The mean age was 42 years. One patient was postmenopausal, and five patients were premenopausal. All of them had a complaint of meno-metrorrhagia. We re-evaluated preoperative sonographic images of patients, and defined 83.3% as well-defined margins, 66.7% hyperechoic, 100% heterogeneous, 66.7% non-cystic, 50% calcification and 66.7% acoustic shadowing. Pathologic features showed mean number of mitosis 8, mild atypia 66.7%, and necrosis 33.3%. In a 24-year-old unmarried female patient with myomectomy, we detected recurrance of tumor in sonographic and MRI studies after 11 months, and confirmed the diagnosis via tru-cut biopsy. There was no relevance between sonographic findings and atypia, necrosis and mitosis. The recurrence was not in relationship with mitosis, degree of atypia and necrosis. We found no relevance between tumor diameter and mitosis, atypia, necrosis and recurrence. CONCLUSIONS: STUMP is classified as an intermediate form, histopathologically so calling it benign or malignant for sure is not possible. Singulary, solidity, hyperechogenicity, heterogenecity and features of acoustic shadowing and margins can guide us to preoperative sonographic diagnosis. Recurrence/metastasis after many years from operation can be seen, and those patients should be followed long term.

ABSTRACT

La brucelosis es un importante problema de salud y, en algunas regiones, es endémica. En ella, es muy frecuente observar un compromiso osteoarticular (20%-60%). En regiones donde es endémica, al analizar la etiología de la artritis, hay que pensar en esta entidad. En este artículo, se informan los casos de 12 pacientes; 11 de ellos eran varones, y la media de edad fue de 12 años (intervalo: de 2 a 17 años). Se determinó el compromiso de la cadera en 9 pacientes; de la articulación sacroilíaca, en 2; y de la rodilla, en 1. Todos los pacientes tenían artralgia; 8 pacientes tuvieron fiebre; y 1 paciente, leucocitosis. A un paciente se lo sometió a un tratamiento quirúrgico debido a artritis séptica. La infección puede derivar en complicaciones graves, especialmente en el compromiso del aparato locomotor. Debe tenerse en cuenta que, mediante el diagnóstico y tratamiento tempranos, es posible prevenir las complicaciones.


Brucellosis is a significant health problem and is endemic in some regions. Osteoarticular involvement is seen most frequently in brucellosis (20-60%). In regions where brucellosis is endemic, it should be considered in the etiology of arthritis. We report the 12 cases, were 11 males with a mean age of 12 years (range, 2-17 years). Involvement was determined in the hip in 9 cases, the sacroiliac joint in 2 and the knee in 1. All the cases had arthralgia, fever was determined in 8 cases and leukocytosis in one case. Surgical treatment was applied to one case because of septic arthritis. Serious complications of the infection may be encountered and particularly in musculoskeletal system involvement, it should be kept in mind that complications can be prevented by early diagnosis and treatment

ABSTRACT

OBJECTIVE: Detection of factors that affect the success of single-dose methotrexate treatment in ectopic pregnancy. MATERIALS AND METHODS: We investigated 99 patients who had been treated with single-dose methotrexate for ectopic pregnancy in our clinic between January 2009 and June 2014. Demographic, clinical, and laboratory results of possible factors that affect treatment success were retrospectively analyzed. Successfully and unsuccessfully treated patients were compared based on their pre-treatment results. RESULTS: The success rate of single-dose methotrexate treatment was found to be 70.7%. No significant difference was found between succesfully and unsuccessfully treated patients before treatment in terms of factors such as gestational weeks, mass size, presence of yolk sac, and presence of free fluid (p=0.224, p=0.201, p=0.200, p=0.200). Serum ß-hCG values in patients whose treatment was unsuccessful was found to be higher compared with the successfully treated group (mean ß-hCG value of unsuccessful group: 4412±3501 mIU/mL; mean ß-hCG value of successful group: 1079±942 mIU/mL; p<0.001). CONCLUSION: Single-dose methotrexate treatment is an effective and reliable method in the treatment of ectopic pregnancy. Elevation of serum ß-hCG value stands as the main prognostic factor that affects the success of single-dose methotrexate treatment.

ABSTRACT

Functional nerve regeneration after reconstructive nerve surgery remains unsatisfying. In this study, vascular endothelial growth factor (VEGF) gene therapy combined with a hyaluronic acid (HA)-enriched microenvironment in nerve regeneration was investigated. Sciatic nerve was transected, and end-to-end neurorrhaphy was performed on 32 male Sprague-Dawley rats, which were randomly divided into four groups (n = 8 per group): nerve coaptation without treatment (group I); nerve coaptation covered with HA film sheath (group II); nerve coaptation with intramuscular VEGF gene in plasmid injection (group III); and nerve coaptation combined with HA film sheath and intramuscular VEGF gene in plasmid injection (group IV). Contralateral sciatic nerves were used as control. VEGF expression was verified from gluteal muscle biopsies surrounding the sciatic nerve by reverse transcriptase-PCR. Electrophysiological, histopathological, and electron microscopic evaluations were performed after 4 weeks. Mean peak amplitude of groups I-IV and nonoperated sciatic nerve were 4.5 ± 0.6 mV, 6.4 ± 0.4 mV, 6.7 ± 0.5 mV, 8.5 ± 0.4 mV, and 9.8 ± 0.5 mV, respectively. Mean myelinated axonal counts of groups I-IV and nonoperated sciatic nerve were 105 ± 24, 165 ± 19, 181 ± 22, 271 ± 23, and 344 ± 17, respectively. Treatment with HA film sheath coverage combined with intramuscular VEGF gene in plasmid injection yielded statistically significant higher peak amplitudes and myelinated axonal counts (P < 0.001). In addition, significantly less scar formation with HA administration (groups II and IV; P < 0.001) was found. Thus, it was found that VEGF might crucially regulate nerve regeneration processes and that HA can reduce the scar formation. This study showed that the combination of HA film sheath and VEGF gene may synergistically promote peripheral nerve regeneration.

ABSTRACT

Neo-vascularisation of the acellular dermal matrix (ADM) is an essential procedure if a full-thickness wound is closed with ADM and skin is grafted over the ADM. In this study, we aimed to improve the neo-vascularisation of ADM by combining the effects of negative pressure wound therapy (NPWT) and mesenchymal stem cells (MSCs) on angiogenesis. In this study, 28 female Sprague-Dawley rats were used and divided into four groups. Full-thickness dorsal skin defects were created in 2 × 2 cm dimensions. The wounds were treated with only the ADM in group 1, the ADM and NPWT in group 2, the ADM and MSCs in group 3 and the ADM, NPWT and MSCs in group 4. By the ninth day of surgery, the excisional biopsy samples were histologically examined to identify the rates of ADM adherence to the recipient bed; the newly formed blood vessels which penetrate the ADM vertically and vascularisation were evaluated by immunohistochemical staining. The graft adherence rates were higher in group 4 than in the other groups statistically, p = 0.003. The numbers of cluster of differentiation 31 (CD31)-stained newly formed microvessels were higher in group 4 than in the other groups statistically, p < 0.05. All subjects in group 4 had the vertical vessels in normal calibration with open lumen vessels which penetrate the ADM. These findings suggest that MSC transplantation induces angiogenesis more efficiently than NPWT. The combination of the NPWT with MSC in this study has shown a synergistic effect on angiogenesis and has affected the neo-vascularisation of the ADM significantly.

ABSTRACT

The objective of this study is to develop a chitosan gel formulation containing liposomes loaded with epidermal growth factor (EGF) and to evaluate their effects on the healing of second-degree burn wounds in rats by immunohistochemical, histochemical and histological methods. EGF-containing multilamellar liposomes which were carried in chitosan gel, EGF gel and EGF-loaded liposome formulations were prepared. The in vivo experiments were performed on female Sprague Dawley rats. Second-degree standard burn wounds were formed on rats and liposomes containing 10 µg/ml EGF in 2% chitosan gel, EGF-chitosan gel and EGF-loaded liposome formulations were applied daily to the burn wounds and biopsies were taken at the 3rd, 7th and 14th day of the treatment. When the results were evaluated immunohistochemically, there were significant increases in cell proliferation observed in the EGF-containing liposome in chitosan gel (ELJ) formulation applied group (P < 0·001). The histochemical results showed that the epithelisation rate in the ELJ group was the highest compared with the other group results (P < 0·001). The histological results indicated and supported these findings and faster epithelisation was observed in the ELJ group compared with the other groups.

ABSTRACT

BACKGROUND: This experimental study was designed to investigate and compare the effects of different anesthesia techniques on rat cremaster muscle flap microcirculation. METHODS: Fifty male Sprague-Dawley rats (130-150 g body weight) were divided into five experimental groups containing ten animals each. Group I, group II, and group III were designated as inhalation, epidural, and spinal anesthesia groups, respectively. Group IV was designated as a combination group for inhalation and epidural anesthesia. Group V was a combination group of inhalation and spinal anesthesia. RESULTS: Group III and group V showed significant increases in the number of rolling and sticking leucocytes and in RBC volume (peripheral stasis) when compared with group I. Blood flow and velocity significantly increased without peripheral stasis in groups II and IV when compared with group I. Although there was no statistically significant difference in the numbers of rolling, sticking, and transmigrating leucocytes or in functional capillary perfusion, group IV had better flow hemodynamics in the peripheral microcirculation when compared with group I. CONCLUSIONS: The inhalation and epidural anesthesia combination was determined to be the ideal anesthesia technique for improved peripheral microcirculation. Spinal anesthesia, either separately or in combination with inhalation anesthesia, has adverse effects on microcirculation.

ABSTRACT

Transport distraction technique is a good treatment modality for unilateral temporomandibular joint ankylosis. However, with a unidirectional distraction, it is not possible to correct facial asymmetry that results from mandibular hypoplasia associated with early-onset unilateral temporomandibular joint ankylosis. For this purpose, gap arthroplasty and simultaneous bidirectional transport distraction was used to correct these deformities. Although vertical distraction corrects vertical deficiency of the ramus and creates a neocondyle, the simultaneous anteroposterior distraction of the transport segment corrects facial asymmetry resulting from horizontal shortness of mandible. Three patients, whose mean mouth opening was 8.6 mm, were successfully treated with this technique. Mean advancements in vertical and anteroposterior direction were 14.7 and 7.7 mm, respectively. Mean maximal mouth opening was 29.7 mm postoperatively. The average follow-up period was 13 months (range, 12-15 mo). During this period, reankylosis was not observed, and the interincisal distance did not decrease. Gap arthroplasty and bidirectional transport distraction of the mandibular ramus is a good and effective therapeutic option in treatment.

ABSTRACT

Inappropriate treatment or untreated fractures of the zygomaticoorbital area results in secondary deformities such as loss of malar projection, enophthalmos, and dystopia. Secondary deformities can be corrected with osteotomies, contour restoration, or a combination of both. Contour restoration can be performed with using onlay grafting with autogenous material or alloplastic implants. In this study, mild to moderate secondary deformities of zygomaticoorbital fractures were corrected with porous a polyethylene implant, which is a highly biocompatible, durable, and stable material. The number of patients who have no surgical treatment at the time of their initial injury was 15, whereas the number of patients who have an initial treatment that resulted in secondary deformities was seven. Twelve of 15 patients had only loss of cheek projection and three of the 15 patients had dystopia and loss of cheek projection. The remaining seven patients had secondary deformities resulting from skeletal surface contour abnormality as a result of comminuted fractures. In 17 of the patients, we used a subciliary approach while using the old incision scar for access in the remainder. In 22 patients, 24 implants were used. Porous polyethylene implant was carved outside in according to the existing contour deficit and was placed in the subperiosteal plane and fixed with titanium screws. The mean follow-up period was 13 months (range, 6-24 months). In this follow-up period, there was no implant extrusion, exposition, infection, or any complication resulting from subciliary incision. Patients were satisfied with the results. The best result can be achieved with porous polyethylene implant in contour restoration of mild to moderate secondary deformities of zygomaticoorbital fractures. The use of this implant in the zygomaticoorbital area is safe and has minimal morbidity.

ABSTRACT

Oxidative stress secondary to ischemia can cause physiopathologic changes that adversely affect wound healing. In this experimental study, we hypothesized that the topical use of esterified glutathione, a well-known antioxidant, can minimize the effects of oxidative stress by an increase in intracellular glutathione and accelerate wound healing by increasing the contraction capacity of fibroblasts and preventing keratinocytes from apoptosis in a rat ischemic wound model. Experimental models were divided into 3 groups as treatment, control, and healthy. Bipedicled flaps were elevated from the dorsum of the rats, and 6-mm punch wounds were created at the end of the first day when the ischemia is most apparent. Wounds were followed histopathologically and immunohistochemically, and matrix metalloproteinase (MMP)-1 and tissue inhibitors of metalloproteinase (TIMP-1) levels were measured by ELISA. Samples were collected at 0, 5, 8, 10, and 12 days. Histopathologic evaluation revealed significant extracellular matrix deposition and reepithelization every fifth day in treatment and healthy groups when compared with control group. Immunohistochemical evaluation revealed increased apoptosis in basal keratinocytes in the control group when compared with the other groups. The evaluation of the samples collected at 5 and 8 days revealed increased MMP-1 levels in treatment and control groups, but the increase in TIMP-1 levels was more significant than MMP-1 levels in treatment group. MMP-1/TIMP-1 ratio was significantly low in the treatment group.Our results showed that topical GSH treatment can reduce oxidative stress, and the reestablishment of the MMP-1/TIMP-1 ratio gives way to adequate and regular extracellular matrix production and reepithelization. It is concluded that esterified GSH, which is experimentally shown to be effective in ischemic wound healing, can be used clinically in ischemic wounds.

ABSTRACT

A 5-year review of 101 cases of zygomatico-orbital fractures is presented. The epidemiology, fracture patterns, treatment modalities, and complications were evaluated in this retrospective study. A majority of fractures were sustained by males and resulted from trauma inflicted during altercations and traffic accidents. The most common fracture pattern was tripod fracture and the most common associated facial fractures were mandibular fractures. Open reduction and rigid fixation was the most frequently employed treatment modality. Depending on the stability of reduced zygoma, one, two and three-point fixations were applied. Orbital floor exploration was performed in 41 cases. Ten out of 16 orbital floor bone defects required reconstruction. In these cases orbital floor was reconstructed with 1.5-mm porous polyethylene implant. Although we encountered a few complications related to the incisions for open reduction, the rate of complication in which correction was difficult (e.g. facial asymmetry) was lower with this approach when compared with the literature.

ABSTRACT

The studies of maxillofacial gunshot injuries mainly focused on evaluating the surgical interventions and physical outcomes of the procedures. In this study we aimed to analyze the pre- and post-injury psychiatric status of the patients with self-inflicted gunshot wounds to the face. This study is based on 12 subjects who attempted suicide resulting in extensive maxillofacial injuries using guns placed beneath their chins. The psychiatric evaluation was conducted by interview and using SCID-I, SCID-II, MMPI, Rosenberg Self-Esteem Scale and Suicide Probability Scale. Two subjects were healthy, 1 had bereavement, 6 had current and 5 had previous MDD (major depressive disorder), 2 had dysthymic disorder, 3 had alcohol abuse, 2 had drug abuse and 4 had antisocial personality disorder. The suicidal group was more socially introverted according to MMPI. According to Rosenberg self-esteem subscale, self esteem, the constancy of self respect and depressive mood subtests were statistically significant in the suicide group compared to the healthy controls (P < 0.01). Depressive spectrum disorders are the most common causes. It is obvious that untreated or undiagnosed depression may increase risk of committing suicide. The changes in the physical facial appearance after the suicide attempt caused impairment of self-esteem and the constancy of self-respect. Similar to other studies, none of our patients reattempted suicide and all tried to return to their pre-injury lifestyle and appeared to accommodate to the stigma of their physical deformities. Early diagnosis and treatment should be considered as a factor to reduce the risk for suicide attempt.

ABSTRACT

Excellent functional and aesthetic results can be achieved in mandibular reconstructions with using free fibular bone flap. However, the vertical deficiency between the reconstructed segment and the occlusal plane made dental rehabilitation impossible in some cases. We encountered this problem in our 3 patients who had mandibular reconstruction with fibular flap due to extensive bone defect result from gunshot injury. To overcome this segmental vertical distraction of the reconstructed mandible was performed. Fibular bone segments (40-70 mm) were distracted with using extraoral distraction device after a latency period of 5-7 days. The rate of distraction was 1 mm/day, and the rhythm was 4 times (4 x 0.25 mm). Distraction was continued until the desired height was achieved, and the distractor left in place for 12 weeks for bony consolidation. No minor or major complications were encountered. The increase of vertical height was between 9 and 13 mm, and it was stable during the follow-up period (7-22 months). Following the vertical distraction and vestibuloplasty operations, the dental restoration of the patients was performed with mandibular removable partial dentures.

ABSTRACT

PURPOSE: The objective of this article is to present the long-term outcomes of ultra-thin polyethylene implants used for orbital floor reconstruction in facial trauma patients. MATERIALS AND METHODS: From 1998 to 2004, 38 patients underwent orbital floor reconstruction with porous polyethylene implants with a mean follow-up of 4 years. A subciliary incision and preexisting facial wounds or scars were used. The boundaries of the maxillofacial injury and the orbital volumes of both orbits were assessed by computed tomography images obtained pre- and postoperatively. In all patients, ultra-thin porous polyethylene implants in various sizes were used to reconstruct the orbital floor defect. RESULTS: None of the patients needed removal of the implants during the follow-up. The volume increase of the traumatized orbits ranged from 0.04 to 6.18 (average 3.12 +/- 1.48) mL compared with the intact orbit (P < 0.01). This difference was not significant postoperatively (P > 0.01). Postoperative ectropion in three cases was corrected under local anesthesia. Persistence of complications were as follows: enophthalmos, 3 in 28; diplopia, 1 in 16; dystopia, 1 in 4; and infraorbital nerve hypoesthesia, 3 in 31. One patient underwent late enucleation of the globe because of initial penetrating trauma. CONCLUSIONS: We recommend the use of ultra-thin porous polyethylene implants in the reconstruction of the orbital floor defects in facial trauma patients. The implants are durable in the long-term and mimic the anatomy of the thin orbital floor and avoid the morbidity of autogenous bone grafts.

ABSTRACT

BACKGROUND: High-energy land-mine explosions cause extensive soft-tissue and bone defects in the heel area, which mostly require free flap coverage. In this article, the authors present the long-term functional outcomes of 72 patients who had free muscle flap reconstructions for composite heel defects caused by land-mine explosions. METHODS: The composite heel defects of 72 male patients caused by land-mine explosions were reconstructed by means of free muscle flaps. The mean follow-up was 6.5 years (range, 1 to 12 years). Each patient completed a questionnaire rating his level of satisfaction. Dynamic foot pressure distribution testing, three-dimensional motion analysis, and dynamic electromyography were performed for all patients. The data were compared with the control group of 20 volunteers. Statistical analysis was performed by Kruskal-Wallis, Mann-Whitney U, and Wilcoxon tests. RESULTS: Dynamic pressure distribution tests revealed significantly higher pressure and load in the injured feet of the patients (p < 0.05). Three-dimensional motion analysis showed restricted range of motion at the ankle joints of the injured extremity (p < 0.05). Seventeen patients were able to stand as long as the control group; the mean standing time for the others was 2.85 hours per day (range, 36 minutes to 5.32 hours). Many of the patients (71 percent) declared their satisfaction of having their own feet instead of prostheses. CONCLUSIONS: This is the longest series documenting the long-term functional results of patients injured by land mines who were treated with free muscle flaps. Reconstructive options should be preferred to amputation procedures in extensive tissue loss caused by land-mine explosion where possible.

ABSTRACT

One of the main subjects that burn researches are focused on is saving the zone of stasis. There are many molecules that are used for this purpose, but all have their drawbacks. Glutathione is one of the major buffer molecules of the cells and is known to increase the thermo-resistance of the cells. In this study, the effect of the systemic glutathione on the zone of stasis was evaluated. The results showed that glutathione is an effective molecule for saving the zone of stasis. It is well-known cheap, and easy to use.

ABSTRACT

In this study, we aimed to investigate the efficacy of cell based dressing with living allogenic keratinocytes in diabetic foot patients. To address this issue, the cultured keratinocytes were attached to the microcarriers produced from polyethylene and silica. The microcarriers were then applied to the wounds at 3-day intervals. Forty patients with grade II and III diabetic foot ulcers were included into the study. The patients were randomised into two groups (n=20). The treatment and control groups received cell based dressing and microcarriers kept in culture medium overnight, respectively. The wound size was recorded at 3 days intervals. The wounds were also categorised by a specific scoring system considering the wound contraction, granulation tissue formation, epithelisation and discharge from the wounds. The high score indicates better condition. The mean reduction of the wound area was 92% in the treatment group and 32% in the control group at the end of the 30 days treatment (p<0.001). When considered the complete healing, the mean number of dressings was 9.2+/-3.2 in the treatment group whereas it was 16.5+/-2.3 in the control group (p<0.001). The initial mean score of the treatment and control groups were 2.5 and 2.35, respectively. At the end of the 30th day, the mean score of the treatment group was 17.15+/-2.7 and of control group was 9.05+/-3. Allogenic keratinocyte treatment delivered with microcarriers can make significant contributions to wound healing in diabetic foot patients.

ABSTRACT

Self-inflicted burns have an increasing incidence all around the world. There is a high mortality and morbidity rate among these patients. We retrospectively analysed the psychiatric characteristics of self-inflicted burn patients. The results showed that these attempts are somewhat different from suicidal acts and may be defined as parasuicides. The treatment and rehabilitation strategies of so called parasuicidal burns are discussed.
