Question Mark Ear: An Unusual Anomaly and a Novel Surgical Technique for Reconstruction.

The question mark ear is a rare abnormality characterized by a cleft between the helix and the earlobe, resulting in a protrusion of the upper part of the ear. The severity of this ear malformation can range from a minor notch in the helix to a complete separation of the helix and the earlobe. In this study, we present a case of a patient with a moderately severe right-sided unilateral question mark deformity. To address this issue, we utilized a novel technique that involves a combination of a Y-V flap with double opposing Z-plasty. Our clinical study demonstrates that using this technique for reconstructing the deformity yields excellent results in terms of the helical rim and fold contour, utilizing solely the local tissues.

Increased Total Antioxidant Capacity Value Improves Survival of Fat Grafts in a Rat Model.

BACKGROUND: While studies aiming to increase fat graft survival continue, in this study, we aimed to investigate the effects of different antioxidants on total antioxidant capacity and their effect on graft survival. METHODS: Thirty-two male Wistar rats were divided into four equally sized groups, including a control group and three antioxidant groups receiving either Melatonin (10mg/kg), Zinc (2mg/kg), or Vitamin E and C (100mg/kg). Autologous fat grafts (1.7± 0.4gr) were transferred to the dorsal subcutaneous region, and total antioxidant capacity was measured on day 0 and 1, week 1 and monthly until the third month. Transferred graft volume and mass (1.3± 0.4gr) were measured using the liquid overflow method and precision scales at the end of the study. Routine hematoxylin-eosin staining and immunohistochemistry against perilipin were performed for semiqualitative analysis and h-score for viable adipose cells, respectively. RESULTS: Collected fat grafts measured significantly less in weight and volume and the survival rate was lower in the control group (p<0.01). Control group exhibited a reduction in TAC, while all groups receiving antioxidants had an increase in TAC during the first week (p=0.02, 0.008, and 0.004 for melatonin, zinc, and vitamins, respectively). Immunohistochemistry of the antioxidant group demonstrated a statistically significant excess and reactivity of cells staining with perilipin antibodies. CONCLUSIONS: In this animal study, the beneficial effect of antioxidants on fat graft survival can be related to the significant increase in TAC following the first week of their administration.

Effects of subepineural hyaluronic acid injection on nerve recovery in a rat sciatic nerve defect model.

BACKGROUND: Maintenance of epineural integrity is very important for nerve healing. Reports on the use of substances consid-ered to have positive effects on nerve healing in experimental nerve defect models are increasing. The present study assessed the effects of sub-epineural hyaluronic acid injection in a rat sciatic nerve defect model that was created while maintaining epineural integrity. METHODS: The study included 40 Sprague Dawley rats. The rats were randomly divided into a control group and three experimental groups (10 rats in each group). In the control group, the sciatic nerve was dissected and no additional surgery was performed. In experimental group 1, the sciatic nerve was transected in the middle, and then, primary repair was performed. In experimental group 2, a 1-cm defect was created while preserving the epineurium, and then, the defect was repaired with end-to-end suturing of the pre-served epineurium. In experimental group 3, the surgical procedure for experimental group 2 was performed, and then, sub-epineural hyaluronic acid injection was carried out. Functional and histological evaluations were performed. RESULTS: On functional evaluation, there was no statistically significant difference among the groups during the 12-week follow-up period. On histological evaluation, nerve recovery was poorer in experimental group 2 than in experimental groups 1 and 3 (p<0.05). CONCLUSION: Although the functional analysis did not reveal any significant results, the histological findings suggest that hyaluronic acid increases the regeneration capacity of axons through its anti-fibrotic and anti-inflammatory effects.

Superior Epididymal Artery-Based Paraepididymal Adipofascial Flap: An Experimental Adipofascial Flap Model in the Rat.

BACKGROUND: Flap surgery is widely performed in reconstructive surgery. Experimental research is vital to improve flap viability. However, the number of flap models for animals is still limited. In this study, we define a new adipofascial flap in rats that can be used to investigate pedicled flap and/or adipofascial flap physiology. METHODS: Eight Wistar male rats were used. Under deep anesthesia, paraepididymal adipofascial flaps were harvested. Flap perfusion was assessed using a near-infrared fluorescence imaging system. The length of the flap and the diameter of the flap pedicle were measured. RESULTS: All animals (n = 8) had sufficient sizes of paraepididymal fat pad, and no animals were lost. The only postoperative complication was testicular hematoma, which was observed in 2 animals. The maximum length of the harvested paraepididymal adipofascial flap was 9.7 cm with a mean of 6.6 cm. The maximum width of the flap was 3.3 cm with a mean of 2.6 cm. The mean pedicle diameter of the paraepididymal adipofascial flap was 1.1 mm. Near-infrared fluorescence imaging revealed adequate perfusion in all flaps. CONCLUSIONS: The number of reported adipofascial flap models in animals is low, and they are mostly limited to flaps based on epigastric vessels. Superior epididymal artery-based paraepididymal adipofascial flap can be used as a pedicled flap model for studies focusing on adipofascial and/or pedicled flap physiology. Uncomplicated surgical technique and short operative time make this flap a valuable alternative to other flap models.

Changing Bacterial Etiology and Antimicrobial Resistance Profiles as Prognostic Determinants of Diabetic Foot Infections: A Ten-Year Retrospective Cohort Study.

Background: In this single-center study, we analyzed a retrospective cohort of patients with diabetic foot infections (DFIs) between 2011 and 2020. Patients and Methods: The first and second five-year periods were compared. A poor prognosis was defined as a primary composite end point including re-infection, major amputation, or mortality at six months. Results: A total of 484 patients were enrolled. Overall, 269 patients had the primary composite end point. A substantial decrease was detected in the second five-year period in terms of re-infection (n = 132, 66.0% vs. n = 68, 23.9%; p < 0.001) and mortality (n = 22, 11.0% vs. n = 7, 2.5%; p < 0.001). A total of 798 micro-organisms were isolated from 484 patients. A substantial increase was detected in polymicrobial infections (48.5% vs. 65.1%; p = 0.001) as well as Streptococcus spp. (2.5% vs. 9.2%; p = 0.003), Corynebacterium spp. (9.5% vs. 22.9%; p < 0.001), and extended-spectrum ß-lactamase (ESBL) producing Escherichia coli (3.0% vs. 12.7%; p < 0.001) in the second five-year period, whereas the prevalence of multi-drug-resistanct (MDR) Pseudomonas aeruginosa (17.0% vs. 10.2%; p = 0.029) and carbapenem-resistant Acinetobacter baumannii (7.5% vs. 2.8%; p = 0.017) decreased. Multivariable regression analysis revealed that MDR Pseudomonas aeruginosa (odds ratio [OR], 1.917; 95% confidence interval [CI], 1.074-3.420; p = 0.028) and carbapenem-resistant Acinetobacter baumannii (OR, 3.069; 95% CI, 1.114-8.453; p = 0.030) were independent predictors for poor prognosis. Conclusions: This 10-year cohort study provides reassuring information about the changing epidemiology of DFIs and the prognostic determinants in patients with DFIs.

[Clinical Characteristics of Mild-Moderate COVID-19 Patients and Risk Factors for the Development of Pneumonia]. / Hafif-Orta Klinik Seyirli COVID-19 Hastalarinin Genel Özellikleri ve Pnömoni Gelisimi için Risk Faktörler.

Limited data exists to date on the predictors for the development of pneumonia in patients with mild and moderate coronavirus (COVID-19). In this study, it was aimed to evaluate the demographic characteristics and clinical findings of mild and moderate COVID-19 and to determine the risk factors for the development of COVID-19 pneumonia in patients admitted to the pandemic outpatient clinic of a university hospital. A total of 414 patients with laboratory confirmed COVID-19 were included. Of these, 220 (53.1%) were male, the mean age was 38.3 ± 12.7. Median duration of hospital admission from the onset of symptoms was three days (0-11). Of the confirmed COVID-19 cases, 154 (37.2%) had a history of family contact and the most common symptoms were weakness (68.4%), myalgia (61.8%), headache (56.5%), loss of smell (45.2%), loss of taste (43.2%) and anorexia (42.8%). Among females, weakness (p= 0.016), headache (p= 0.008), sore throat (p= 0.032), nausea (p= 0.003), anorexia (p= 0.045), loss of taste (p= 0.005) and loss of smell (p<0.001) were more common. Loss of taste (47.6% vs. 25%, p<0.001) and loss of smell (50% vs. 26.3%, p<0.001) were more common in patients with under the age of 50 and cough (43.4% vs. 29.3%, p= 0.003) was more common in patients with above the age of 40. Among 46 (11.1%) patients with asymptomatic COVID-19, there was no significant difference (p= 0.500) between the genders. Pneumonia was detected in 150 (43.8%) of 339 patients who underwent thorax computed tomography. In the univariate analysis; advanced age (p<0.001, odds ratio (OR)= 1.44), obesity (p<0.001 OR= 2.5), not being actively smoking (p<0.001, OR= 6.19), fever at first admission (p= 0.002, OR= 2.02), cough (p<0.001, OR= 3.26), shortness of breath (p<0.001, OR= 23.37), weakness (p= 0.042, OR= 1.63), anorexia (p= 0.009, OR= 1.79) and elevation of D-dimer (p= 0.014, OR= 1.92) were associated with the development of pneumonia. In multivariate analysis, obesity (p= 0.005, OR= 2.69), not being actively smoking (p<0.001, OR= 5.43), cough at first admission p= 0.017, OR= 2.16) and shortness of breath (p= 0.008, OR= 16.22) was determined as an independent risk factor for the development of pneumonia. CRP (p<0.001), D-dimer (p<0.001), ferritin (p<0.001) values among 108 (26.1%) patients with a body-mass index(BMI) >30 were high, and 60.9% of the patients had pneumonia (p<0.001) . CRP (p<0.001), D-dimer (p= 0.010) values were low, lymphocyte count (p= 0.001) was high among 106 (25.6%) active smokers, and 15.6% of the patients had pneumonia (p<0.001). Of the patients reported with persistent symptoms, 25.9% had loss of smell, 25% had weakness, and 23.1% had loss of taste on the seventh day; 21.1% had loss of smell, 21.1% had myalgia, and 19.7% had loss of taste on the 14th day. During their follow-up, the COVID-19 polymerase chain reaction (PCR) test was studied in 286 patients for control purposes. The median time of being negative for COVID-19 PCR test was eight days (3-56). In conclusion, symptoms may last longer than 14 days in 20- 30% of patients presenting with mild-moderate clinical findings. In addition, obesity should be considered as an important risk factor for COVID-19 pneumonia.

Effects of Cigarette Smoke on Fat Graft Survival in an Experimental Rat Model.

INTRODUCTION: A fat graft is the closest thing to being the ideal soft tissue filler. Although it has many advantages, reliability of late-term survival is a never-ending debate. Although there are observational studies that research the effect of cigarette smoke on fat graft take in clinical setting, there has not been an objective experimental animal study on the affect of smoking on fat graft survival. The aim of our study is to search if smoking has an affect on fat grafts. MATERIALS AND METHODS: Twenty-two Sprague-Dawley type rats were used. Exposure was maintained via a passive smoke exposure system. Rats were divided into three groups regarding their exposure period. At the end of the study, transferred fat grafts were extracted and weighed with a precision scale, an arterial blood sample was taken for biochemical analysis, and grafts were sent to the pathology laboratory for immunohistochemical assessment. RESULTS: There were meaningful differences between the control group and the other two groups in graft weight loss, serum cotinine, tissue MDA, adipose tissue/fibrosis ratio, stem cell counts, perilipin positive cell density and inflammation density. Furthermore, we detected meaningful correlations between serum cotinine, tissue MDA and graft weight loss. CONCLUSION: Fat graft takes with the same mechanisms as a wound heals. So like wound healing, cigarette smoke has a negative affect on fat graft survival. A fat graft is by its nature an elective procedure so to improve our late-term success, cigarette smoke exposure should be kept to a minimum for increased reliability.

The New Anatomical Classification System for Orbital Exenteration Defect.

BACKGROUND: The unique anatomy of the orbita and the different behavior of each malignant tumor cause us to perform the various types of orbital exenteration that yields to varying defect each of which has own specific demands in terms of the reconstruction. Current classification of orbital exenteration defects seems not to be adequate to provide detailed description. This study reviews 50 exenteration defects to offer a more effective anatomical classification system. METHODS: Over a 15 years period, 50 orbital exenteration defects in 47 patients were reconstructed. Defects were categorized according to the resected orbital wall, dura, and ethmoid resection. If the maxillectomy was performed, A or B was added to define the type of maxillectomy as partial (intact palate) or total maxillectomy, respectively. According to these criteria, 4 types of defect patterns were determined including Type 0 (n = 5) with intact orbital wall, Type I (n = 9) with sino-orbital fistula, Type II (n = 4) with crania-orbital fistula with intact dura, Type III (n = 6) with crania-orbital fistula associated with dura defect, and Type IV (n = 8) with cranio-nasal-orbital fistula. There were 12 partial (A) and 6 total maxillectomy (B) defects along with the orbital exenteration. RESULTS: There was no major complication except one. The minor wound-healing problems occurred in 7 patients. Nine patients (19%) used prosthesis. Twenty-two (46.8%) patients chose a patch to cover the area. The remaining 16 patients were not able to use any type of prosthesis because of the reconstruction methods. CONCLUSION: The authors believe that the authors' anatomical classification system provides more precise description of the defect which eventually enhances the success rate of both reconstruction and resection.

Origin, Reality, and Clinical Importance of the Arcade of Struthers: An Anatomic Study.

The literature contains confusing and opposing views about the naming, prevalence, anatomic structure, and clinical significance of the arcade of Struthers. The conflicting rates of arcade (between 0% and 100%) prevalence found in the literature may be due to the varying definition of the arcade among the authors, as well as the dissection method. The present study aims to examine the structure to determine whether or not the arcade of Struthers exists through an anatomic dissection study of a fresh human cadaver and seeks to compare its findings with those in the literature. Twenty arms from fresh frozen cadavers were dissected. An arcade of Struthers was not found in any specimen. Study concluded that its existence is unproven, and the arcade of Struthers does not exist.

Mandibular metastases of papillary thyroid carcinoma treated by hemimandibulectomy and costochondral rib graft.

Papillary thyroid carcinoma (PTC) is the most common and well-differentiated cancer of the thyroid. Unlike most cancers, spread to local lymph node does not worsen the survival rate of PTC, and complete resection of the metastases seems to be important and may have favorable effects on the prognosis. A 33-year-old woman was referred to our clinic with a mass involving the right angulus mandible. Incisional biopsy of the mass diagnosed follicular variant of papillary thyroid carcinoma. Right hemimandibulectomy was performed and reconstructed with costochondral rib graft. The patient survived for 5 years after the hemimandibulectomy. Metastases to the oral cavity indicate a grave prognosis, but PTC has relatively indolent biological behavior; long-term survival is usually possible even in patients with metastatic disease.

Psychiatric disorders and their association with burn-related factors in children with burn injury.

BACKGROUND: The aim of this study was to assess psychiatric disorders and their association with burn-related factors in a population of Turkish children with burns. METHODS: Thirty-one children admitted to the Cerrahpasa Medical Faculty Burn Unit between January 2013 and August 2013 were first assessed by the plastic surgeon, and then those with psychological symptoms were referred to a child psychiatrist, and the records were analyzed retrospectively. RESULTS: The percentage of burned area to Total Body Surface Area (TBSA) ranged between 2-60% (mean, 17.3%). Nineteen patients (61.3%) had a psychiatric diagnosis, which included acute stress disorder (ASD) (n=15), depression (n=3), posttraumatic stress disorder (n=2, comorbid with depression), and delirium (n=1). The percentage of burned area to TBSA was associated with the presence of psychopathology and ASD. Further, psychopathology was associated with the number of burned major body regions. CONCLUSION: Pediatric burn patients are at risk of developing psychopathology. The children with a greater percentage of burned area to TBSA and more burned body regions have the greatest risk of psychopathology. Surgeons have an important role in patient referral for psychiatric interventions, so that psychiatric disorders can be prevented as early as possible.

Epidemiology of pediatric burn injuries in Istanbul, Turkey.

BACKGROUND: Many burns that occur in the first two decades of life are accidental and preventable. The aim of this study was to determine the demographic features, mortality, and other factors associated with pediatric burns in Istanbul, Turkey. METHODS: Our retrospective study included 375 hospitalized pediatric patients (225 male, 150 female; mean age 4.07±3.79; range 0.2 to 16 years) aged 16 years or less admitted between January 2005 and January 2009. Each child's medical record was reviewed and demographic features, mechanism of burn, place of residence, total body surface area (TBSA), surgical treatment, duration of hospital stay and mortality rates were analyzed. RESULTS: Scalding was the predominant cause among all pediatric age groups. There were no differences between the age groups with respect to mean TBSA. Length of hospital stay in infants and toddler age group was significantly lower than in other age groups (p<0.005). Sixteen (4.3%) patients died during the study period. Mortality rates associated with scalding, flame and electrical burns were 3.1%, 13.9% and 10%, respectively. Electrical burns and flame resulted in significantly higher mortality rates than scalding (p<0.05). CONCLUSION: Scalding was found to be the most important cause of burns and flame-related mechanisms resulted in the highest mortality rate among children. Only a specific preventive program for changing the traditional habits of Turkish parents would reduce burn injuries among children.

Surgical treatment of axillary accessory breasts.

Accessory breast tissue is a remnant persisting after normal embryological development of the breast. Although accessory breasts may be asymptomatic, they can cause discomfort during menstruation, anxiety, cosmetic problems, pain, or restriction of arm movement. The data of all patients who presented with axillary accessory breasts between January 2000 and September 2008 were recruited from a computer database. Medical charts, outpatient records, operative notes, and pathology reports were reviewed. A total of 29 patients underwent surgical treatment of axillary accessory breasts in the Department of Breast Surgery and Department of Plastic, Reconstructive and Aesthetic Surgery. The ages of the patients at the time of surgery ranged from 19 to 54 years. The mean age was 28.8 years. All patients were female. Sixteen patients had unilateral accessory breast and 13 patients had bilateral accessory breasts. Fourteen patients had breast hypertrophy. Twenty-one patients had excision, five patients had liposuction, and three patients had both. Axillary accessory breasts can be satisfactorily treated with excision, liposuction, or both. In patients with concomitant macromastia, reduction mammaplasty and removal of accessory breasts can be performed at the same time with no additional morbidity.

Reverse-flow retroauricular island flap in facial reconstruction.

BACKGROUND: Reconstruction of facial skin defects requires good-quality skin cover to satisfy aesthetic expectations of patient, especially when the skin defect is on the uncovered area of the face. Limitations in the available local tissue and donor-site morbidity restrict the options. OBJECTIVE: In an effort to solve these problems, we have begun to use a subcutaneous pedicled retroauricular reverse-flow flap. METHODS: Between January 1997 and December 2005, reverse-flow subcutaneous pedicled retroauricular island flap was used to cover facial defects in 12 patients who underwent surgical excision of skin tumor. The patients ranged in age from 44 to 81 years with a mean age of 58 years. RESULTS: Only one case experienced a superficial necrosis in the distal one-quarter part of the flap. The functional and aesthetic results were satisfactory for both patients and surgeons, and no tumor recurrence was observed during the 12 to 28 months (mean, 18.8 months) follow-up period. CONCLUSIONS: This flap can be used reliably for the reconstruction of facial skin defects of small and medium size. The preference of frontal branch pedicled flap enables more distal facial area defects to be covered, such as dorsal nasal, nasolabial, and upper lip, than flaps based on parietal branch.

The effect of hematoma in muscle flap microcirculation.

Free radicals were first mentioned by Healey about the hematoma under skin flaps, trying to explain the blood itself has different effect beyond its space-occupying effect or infection. The aim of this study was to determine whether hematoma would have any effect on neutrophil behavior in muscle flap microcirculation. Rat cremaster muscle flap model was used for measuring intravital different parameters. We used the rat cremaster muscle flap model for direct observation and measurement of rolling and adhesion. The rats were randomized into 6 groups. Groups I and IV: only the cremaster muscle was turned to the abdominal wall (n = 4 and n = 4). Groups II and V: saline was injected under the muscle flap (n = 3 and n = 4). Group III and VI: blood was injected under the muscle flap (n = 4 and n = 5). Two sets of microcirculatory measurements were taken in each group. For the comparisons of the groups, the measurements that were taken at the second hour and at the sixth hour were standardized according to the baseline values of the same groups in the same postcapillary venules. Comparisons within the groups were made by Student t test. Between the groups, analysis of variance (ANOVA) independent test was used.Within groups, the number of adherent neutrophils in the second and sixth hour in hematoma groups were found significantly increased according to the baseline measurements, and the number of rolling neutrophils in the second hour in hematoma group was found increased according to the baseline measurements. Between groups, the number of rolling neutrophils in the second hour was found significantly increased between hematoma and sham/hematoma and control groups and the number of adherent neutrophils in the second and sixth hour was found significantly increased between hematoma and sham/hematoma and control groups.

Does random pattern skin flap supply adequate circulation to the underlying muscle through musculocutaneous perforators by reverse flow? An experimental study.

An experimental study was designed to examine whether the blood supply of the muscle would be maintained by a reverse flow from the random pattern skin flap through the musculocutaneous perforators. A flap model containing rat rectus abdominis muscle and randomly based overlying abdominal skin was designed. Sixty rats were divided into four experimental groups as follows. In group I, scintigraphy and microangiography were performed in 10 and 6 rats, respectively, immediately after flap elevation. In group II, scintigraphy and microangiography were performed in 10 and 6 rats, respectively, 2 days after flap elevation. In group III, surviving skin paddle area was evaluated in 16 rats 7 days after flap elevation. After evaluation of surviving skin paddle area, the same animals were used for microangiographic (n=6) and scintigraphic (n=10) studies at the same day. In group IV, histopathologic examination was done in six flap muscles each 2 and 6 weeks after flap elevation (n=12). The mean percentage of surviving skin paddle area was 95.6 +/- 6.5% on postoperative day 7. Microangiography showed progressively developed blood flow from the skin to muscle through the musculocutaneous perforators in groups II and III, respectively. The radioisotope uptake of the operated muscle was 40.9 +/- 12.8% immediately after flap elevation (group I), 58.3 +/- 15.6% on postoperative day 2 (group II), and 70.7 +/- 25.6% on postoperative day 7 (group III). There was a significant difference only between group I and group III ( P<0.05, analysis of variance). Histopathologically prominent atrophy, lipomatoses, and fibroses were revealed at week 6. The poor circulation and viability outcomes of the muscle revealed in the study are because of immediately insufficient blood microcirculation at the distal part of the random pattern skin flap.

Crossover replantation of the foot after bilateral traumatic lower extremity amputation.

BACKGROUND: Bilateral traumatic amputation and limb-threatening injury of the lower extremities is more challenging than the unilateral amputation. Successful replantation of both lower extremities has been reported previously. However, orthotopic implantations may not be possible when amputation of both lower limbs with different levels of section and degrees of damage to surrounding tissues occurs. It was reported that the crossover replanted foot in combination with prosthetic limb is better than 2 artificial limbs. Hence, crossover replantation should be considered when anatomic replantation of both lower extremities is not possible as a result of bilateral total or subtotal amputation. To our knowledge, there are few reports about the crossover replantation of the lower extremity in the literature. CASE REPORT: A 30-year-old engineer being run over by the train had crushed the bilateral lower limbs in different anatomic levels. We decided to perform the crossover replantation of the right foot to the stump of the left leg to provide the patient with at least 1 weight-bearing sensate extremity. At the latest follow-up examination, 30 months after the operation, he had mild pain, especially in toes of the replanted foot. There was no ulceration in both the replanted extremity and the right amputation stump. The sole has maintained complete protective sensation. The patient described the functional result of the reimplanted leg as satisfying and better than the prosthesis that has caused much more problems than the replanted extremity. He had no complaint about the cosmetic result. He stated that he would have the crossover replantation again under the same condition. He was able to return to his previous job. Moreover, he affirmed that he is able to carry on his all social activities as he had done before the accident except for playing football. In conclusion, the possibility of the crossover replantation should be considered while evaluating the patient with bilateral lower limb injuries to allow the patient to stand on their own foot and still touch ground.

Fournier's gangrene: a retrospective clinical study on forty-one patients.

BACKGROUND: Fournier's gangrene, first described by Dr Jean Alfred Fournier in 1883, still has a high mortality rate. The prognosis and outcome of such patients were analysed. METHODS: Forty-one patients with Fournier's gangrene were reviewed on the parameters of age, sex, aetiological agents, predisposing factors, treatment modalities and outcomes. RESULTS: Although early intervention and careful treatment was carried out, nine of 41 patients (21.9%) died as a result of complications of septicemia. Among the treatment modalities, there were extensive debridement, drainage, excisions of the skin and fascia, colostomy procedure, extensive antibiotic treatment and hyperbaric oxygen therapy. Although a combination of different treatment modalities were used, the mortality rate was 21.9%. CONCLUSIONS: Fournier's gangrene is still a severe disease. Today, hyperbaric oxygen treatment is very effective in the treatment of this disease.

[The role of supplementation or inhibition of nitric oxide production in burn injury to reduce ischemic damage]. / Yanikta nitrik oksit üremtiminin desteklenmesi veya azaltilmasinin iskemik hasari azaltmadaki rolü.

BACKGROUND: To determine the role of nitric oxide (NO) which is vasodilator agent and inflammatory cytokine, in burn injury. METHODS: Rats were divided into 5 groups, and a 30 % burn was inflicted. In addition to sham control and burn control groups, other 3 groups were given L-Arginine, and L-nitro-L-Arginine methylester (L-NAME), and both. Neutrophil and hematocrit percentage in blood, NO, TNF-alpha and malondialdehyde (MDA) levels in plasma and neutrophil infiltration in the lung were evaluated at 24 hours after thermal injury. RESULTS: The inhibition of NO production with L-NAME treatment significantly decreased these parameters when compared to burned control group. MDA was decreased significantly in all groups which were given drugs. CONCLUSION: The induction and inhibition of NO production both reduced lipid peroxidation but induction increased the mortality, plasma TNF-alpha and neutrophil in the blood. Inhibition of NO production is found more useful after thermal injury in rats.

Labiocolumellar graft combined with tip graft in the management of inadequate tip projection.

The short distance of the nasal tip from the alar crease indicates inadequate projection. Tip grafts are commonly used for the management of this problem. In addition to tip grafts, labiocolumellar augmentation by cartilage grafts also provides further elevation of the tip complex for patients with poor tip definition, excessive alar base width, inadequate tip projection, or plunging nasal tip. In addition to standard rhinoplasty procedure and tip grafting for nasal tip augmentation, a linear cartilage graft was inserted centrally just behind the labiocolumellar angle for further tip elevation. The graft was placed in the subdermal plane just anterior to the orbicularis oris muscle to prevent graft displacement and clicking during muscle motion. This procedure was performed for 45 rhinoplasty patients, only three of whom underwent tip plasty procedures alone. During 1 year, 43 patients were followed up. Most of the patients (75%) were satisfied with the results of the procedure. Tip graft combined with labiocolumellar graft is an effective technique for obtaining satisfactory tip projection and correcting the acute labiocolumellar angle.
