Neuroendocrine Tumour of the Gallbladder Diagnosed after Cholecystectomy.

Gallbladder cancer is a rare but aggressive malignancy. Neuroendocrine tumour of the gallbladder make up 2-3% of all the gallbladder tumour. A 67-year female patient underwent laparoscopic cholecystectomy because of symptomatic cholelithiasis and the histopathology revealed a neuroendocrine tumour of the gallbladder, stage pT2a. The patient's imaging study for metastasis workup were normal. A radical cholecystectomy procedure was planned as the tumour stage was pT2a. Postoperative chemotherapy and/or radiotherapy were recommended. The patient, who had comorbidities, was refused both surgery and other treatment alternatives. The patient's one-year clinical, laboratory, and radiological follow-up did not reveal any findings of recurrence or metastasis. There is no standardised staging system for neuroendocrine tumours of the gallbladder since the number of such cases is quite limited. Guidelines are also insufficient. Multi-centred and large studies are needed in order to develop standardisation in treatment, prognosis, and factors affecting survival.

Factors Affecting Recurrence of Idiopathic Granulomatous Mastitis.

OBJECTIVE: To investigate factors that may have an effect on recurrence by retrospectively analysing the data of patients who were followed up and treated for idiopathic granulomatous mastitis in this clinic. STUDY DESIGN: Analytic study. PLACE AND DURATION OF STUDY: Department of General Surgery, Faculty of Medicine, Baskent University, Konya and Adana Practice and Research Hospitals between January 2010 and January 2021. METHODOLOGY: The data of patients who were histopathologically diagnosed with granulomatous mastitis were retrospectively analysed. The patients included in the study were divided into two groups: Recurrence (Group 1) and non-recurrence (Group 2). Patients with underlying etiological factors that may cause granulomatous inflammation such as infection, trauma, tuberculosis, sarcoidosis, and autoimmune disease were excluded from the study. The effects of other parameters (involvement area, follow-up duration, the time from the onset of complaints to diagnosis, side of involvement, breastfeeding, oral contraceptive use, redness, ulceration and/or discharge, preoperative histopathological diagnosis, diagnosis by any of the preoperative imaging techniques, preferred treatment method) on recurrence, were statistically analysed. RESULTS: Furthermore, the analysis results showed no significant difference between the groups with and without recurrence with regard to any of the other variables such as follow-up period, size of the involvement area, presenting complaints, breast-feeding, preferred treatment alternative (steroid, steroid + surgery, surgery), and preferred surgical technique (p>0.05). The time from the onset of complaints to diagnosis was significantly longer in the recurrence group (p=0.001). In addition, the frequency of oral contraceptive use was statistically significantly higher in the recurrence group (Odds ratio=7.6, p=0.044). CONCLUSION: The results of this study suggest that early diagnosis could prevent recurrence in patients with idiopathic granulomatous mastitis. Prospective randomised controlled studies are needed to support this thought. Key Words: Idiopathic granulomatous mastitis, Malignancy, Oral contraceptive, Steroid.

A model for acute kidney injury in severe burn patients.

INTRODUCTION: In patients with severe burns, morbidity and mortality are high. One factor related to poor prognosis is acute kidney injury. According to the AKIN criteria, acute kidney injury has 3 stages based on urine output, serum creatinine level, and renal replacement therapy. In this study, we aimed to create a decision tree for estimating risk of acute kidney injury in patients with severe burn injuries. METHODS: We retrospectively evaluated 437 adult patients with ≥20% total burn surface area injury who were treated at the Baskent University Ankara and Konya Burn Centers from January 2000 to March 2020. Patients who had high-voltage burn and previous history of kidney disease were excluded. Patient demographics, medical history, mechanism of injury, presence of inhalation injury, depth of burn, laboratory values, presence of oliguria, need for renal replacement therapy, central venous pressure, and prognosis were evaluated. These data were used in a "decision tree method" to create the Baskent University model to estimate risk of acute kidney injury in severe burn patients. RESULTS: Our model provided an accuracy of 71.09% for risk estimation. Of 172 patients, 78 (45%) had different degrees of acute kidney injury, with 26 of these (15.1%) receiving renal replacement therapy. Our model showed that total burn surface area was the most important factor for estimation of acute kidney injury occurrence. Other important factors included serum creatinine value, burn injury severity score, hemoglobin value, neutrophil-to-lymphocyte ratio, and platelet count. CONCLUSION: The Baskent University model for acute kidney injury may be helpful to determine risk of acute kidney injury in burn patients. This determination would allow appropriate treatment to be given to high-risk patients in the early period, reducing the incidence of acute kidney injury.

Comparison of Ultrasound-Guided Erector Spinae Plane Block and Subcostal Transversus Abdominis Plane Block for Postoperative Analgesia after Laparoscopic Cholecystectomy: A Randomized, Controlled Trial.

PURPOSE: Laparoscopic cholecystectomy causes moderate to severe pain despite its minimally invasive nature. This study was performed to compare the efficacy of the bilateral erector spinae plane block (ESPB) and the subcostal transversus abdominis plane block (STAPB) under ultrasound guidance. METHODS: 64 patients were included in this prospective, randomized study. The patients were allocated into two groups as those receiving ESPB (n = 32) and those receiving STAPB (n = 32). Pain scores at rest and during movement, fentanyl requirement, postoperative walking time, and duration of hospital stay were compared. The complications which related to block were also recorded. RESULTS: In the ESPB group, the Numeric Rating Scale (NRS) scores at rest were lower at hour 0 [at the time of post-anesthetic care unit (PACU) admission] and postoperative hours 2, 4, 6, and 12 (p < 0.05). In the same group, the NRS scores at movement were lower at hours 0, 2, 4, 6, 12, and 24 (p < 0.05). In the ESPB group, the time to first analgesic need was longer (p < 0.05), intraoperative and postoperative Fentanyl requirement (p < 0.0001 for both) and PACU rescue analgesic requirement were lower (p < 0.05), the lengths of PACU and hospital stay were shorter (p < 0.0001), and unassisted walking time was shorter (p < 0.0001). There were no complications related to the block in either group. CONCLUSION: Bilateral ultrasound-guided ESPB provides superior analgesia after laparoscopic cholecystectomy surgery compared to STAPB and further reduces unaided walking time and hospital stay.

The Number of Patients Diagnosed with Brain Death and Organ Donation Rates at the Baskent University Konya Hospital: 6-Year Experience.

OBJECTIVES: Kidney transplant started at Baskent University Konya Hospital in July 2016. In this study, we compared the causes of brain death and the organ donation rates in our center between 2013 and 2016 versus between 2016 and 2019. MATERIALS AND METHODS: Patient files and records were analyzed retrospectively. Age, biologic sex, cause of brain death, and organ donation rates of patients diagnosed with brain death were examined and compared. RESULTS: The number of patients who were diagnosed with brain death and became deceased donors at our center increased 4-fold during the period from 2016 to 2019 compared with that shown from 2013 to 2016. In addition, organ donation rates increased to 71.4%, which is much higher than the average in Turkey (24%-28%). Between 2013 and 2016, trauma was the leading cause of brain death (42.8%), whereas between 2016 and 2019 cerebral hemorrhages rose to first place with a rate of 89.3%. In 2018 and 2019, there were 199 and 62 brain deaths, respectively, reported in our organ donation coordination region with an approximate organ donation rate of 25%. In our center, 12 patients were diagnosed with brain death in 2018 and 8 of these patients (66.7%) became donors; 6 brain deaths were diagnosed in 2019, and 4 patients (66.7%) became donors. Since we started kidney transplant at our center in 2016, the number of patients diagnosed with brain death has increased significantly. CONCLUSIONS: Establishing a healthy communication with relatives of patients and having a dedicated organ transplant center are important reasons for our much higher organ donation rates compared with the general rate in Turkey. A healthy communication is the most effective way to establish trust with next-of-kin and the general public.

Cutaneous Bone Formation Associated With Melanocytic Nevus.

AIM: Cutaneous bone formation is an uncommon lesion of the skin. It may be primary or secondary. Secondary lesions are mostly associated with melanocytic nevi. Although many different theories have been proposed to explain the etiology, extraskeletal bone formation is complex and poorly understood phenomenon.Here the authors report a series of melanocytic nevi with cutaneous bone formation and the authors described morphologic and clinicopathologic features such as age, sex, location, focus number and size of the lesion. MATERIAL AND METHOD: Through a single center, this retrospective study presents total number of 20 patients with melanocytic nevus with or without osseous metaplasia. Histologic and clinicopathologic features such as age, sex, location, focus, and size of lesion were compared. RESULTS: Lesions were identified in 10 female patients. All of the cases were seen in the head and neck region such as face, forehead, eyebrow, lip, and neck and most of them were solitary. The nevi were usually associated with the single focus of ossification. Most of patients (50%) had acne symptoms and treatment anamnesis. Granulomatous dermal inflammation was seen in 2 patients. There was no difference in nevus morphology and the size of the nevi between the osteonevi and the other types of nevi. CONCLUSION: In conclusion, this study revealed that although it is rare it has distinctive features such as female patients, face location, and acne anamnesis. Therefore it may be speculated that the osteogenic factors may be involved with inflammatory-induced metaplastic ossification and tend to be related female sex.

Effects of Single-Dose Preemptive Pregabalin and Intravenous Ibuprofen on Postoperative Opioid Consumption and Acute Pain after Laparoscopic Cholecystectomy.

PURPOSE: Non-opioid medications as a part of multimodal analgesia has been increasingly suggested in the management of acute post-surgical pain. The present study was planned to compare the efficacy of the combination of pregabalin plus iv ibuprofen. METHODS: 58 patients were included in this prospective, randomized, double-blinded study. The pregabalin group (Group P, n = 29) received 150 mg pregabalin, the pregabalin plus ibuprofen group (Gropu PI, n = 29) received 150 mg pregabalin and 400mg iv ibuprofen before surgery. Postoperative fentanyl consumption, additional analgesia requirements and PACU stay were recorded. Postoperative analgesia was performed with patient-controlled IV fentanyl. RESULTS: VAS scores in the group PI were statistically lower at PACU, 1and 2 hours at rest, at PACU, 1, 2, 4, 12 and 24 hours on movement compared to the group P (P < 0.05). Opioid consumption was statistically significantly higher in the group P compared to the group PI (130.17 ± 60.27 vs 78.45 ± 60.40 µq, respectively, P < 0.001) and reduced in the 4th 24 hours by 55% in group PI. Rescue analgesia usage was statistically significantly higher in the group P than in the group PI (16/29 vs 7/29, respectively, P < 0.001). Four patient in the group PI did not need any opioid drug. Besides, PACU stay was shorter in the group PI than the group P (10.62 ± 2.38 vs 15.59 ± 2.11 min, respectively, P < 0.001). CONCLUSION: Preemptive pregabalin plus iv ibuprofen in laparoscopic cholecystectomy reduced postoperative opioid consumption. This multimodal analgesic aproach generated lower pain scores in the postoperative period.

The Rare Benign Lesion That Mimics a Malignant Tumor in Breast Parenchyma: Nodular Fasciitis of the Breast.

We herein report the clinical and pathological findings of a rare case of nodular fasciitis in the breast parenchyma of a 48-year-old female. Because of potentially malignant findings on ultrasonography and during clinical examination, the patient underwent an excisional biopsy. Histologically, the lesion was composed of spindle to round shaped cells arranged in short bundles in a storiform pattern. Immunohistochemically, the cells were positive for vimentin and SMA and negative for desmin, S100, and CD34. Based on these morphological and immunohistochemical features, a diagnosis of nodular fasciitis was made. We emphasize that nodular fasciitis of the breast may show clinical features and imaging findings similar to those of breast cancer. The histopathologic diagnosis of nodular fasciitis can also be challenging. The purpose of this case report is to highlight the characteristics and the differential diagnosis of this rare neoplasm.

The effect of pneumoperitoneum on the cross-sectional areas of internal jugular vein and subclavian vein in laparoscopic cholecystectomy operation.

BACKGROUND: Increased central venous pressure secondary to an increase in intraabdominal pressure has been reported during laparoscopic surgery. However, no study has yet determined the effect of pneumoperitoneum on cross-sectional area (CSA) of central veins by ultrasonography during laparoscopic cholecystectomy. Herein, we aimed to quantify changes in CSAs of internal jugular (IJV) and subclavian veins (SCV) by ultrasonography during this surgery. METHODS: This study included 60 ASA I-II patients scheduled for laparoscopic cholecystectomy surgery under general anesthesia. Pneumoperitoneum was performed with CO2 at 12 mmHg. The CSAs of right IJV and right SCV were measured using a 6 Mhz ultrasonography transducer in supine and neutral positions before anesthesia induction (T1), 5 min after connecting to mechanical ventilator (T2), 5 min after creation of pneumoperitoneum (T3), at the end of pneumoperitoneum (T4), and 5 min after desufflation and before extubation (T5) both at end-expiration and end-inspiration. RESULTS: The comparison of IJV CSA at inspiration showed significant increase in T3 value compared to T2 value (p < 0.001). Similarly the expiratory measurements of IJV CSA demonstrated significant increase in T3 value compared to T2 value (p < 0.001). The comparison of inspiratory CSA measurements of SCV showed significantly increased in T3 (p = 0.009) than T2 value. In expiratory measurements there was a significant increase in T3 (p = 0.032) value compared to T2. All measurements of IJV and SCV SCAs both end-inspiration and end-expiration T5 values significantly decreased compared to T4 values (p < 0.001). CONCLUSIONS: Pneumoperitoneum with an intraabdominal pressure of 12 mmHg produces significant increases in IJV and SCV CSAs during laparoscopic cholecystectomy procedure. We believe that this finding may enhance our understanding of pneumoperitoneum-induced hemodynamic changes and facilitate catheterization attempts. TRIAL REGISTRATION: Date of registration 21/07/2016, ISRCTN Registry ( No: ISRCTN15164056 , registered retrospectively).

Estimation of the capacity of emergency surgery in Konya: Nine-year multicenter study.

OBJECTIVE: Although the number of surgical emergencies continues to increase, comprehensive data on emergency surgical admissions are scarce. The aim of this multicenter study was to evaluate the causes, management, and outcomes of the general surgical emergencies in the city of Konya, Turkey. MATERIAL AND METHODS: The relevant details of the cases admitted and considered to be general surgical emergencies in Konya over a nine-year period (January 2003-January 2012) were analyzed. All demographic data were analyzed statistically. RESULTS: The study group comprised 21954 cases from 4 hospitals in Konya: 7154 from Konya Numune Hospital, 6,654 from Konya Education and Research Hospital, 6,400 from Necmettin Erbakan University Meram Medical Faculty, and 1,390 from Baskent University Konya Education and Research Hospital. Their mean age was 59.6 years, and the average hospitalization time was 3.3 days. The diagnoses of the admitted patients were as follows: acute appendicitis (59.57%), bowel obstruction (11.12%), trauma (7.97%), strangulated inguinal hernia (5.46%), acute cholecystitis (4.87%), peptic ulcer perforation (4.09%), mesenteric ischemia (2.73%), necrotizing fasciitis (2.73%), gastrointestinal system bleeding (1.79%), and others (1.1%). CONCLUSION: The findings of the study indicate a steady increase in surgical admissions to emergency units. Non-traumatic acute abdomen was the most common reason for general surgical emergencies. Although the number of elderly patients increased, the hospital stay and mortality rates decreased over the study period.

Coronary Flow Velocity Reserve in Burn Injury: A Prospective Clinical Cohort Study.

The authors sought to evaluate coronary microvascular function and left ventricular diastolic dysfunction using transthoracic Doppler echocardiography in burn patients. In this study, 32 adult burn patients with partial or full-thickness scald burns that were hospitalized and treated were included. The control group was matched for age and sex and was composed of otherwise healthy volunteers. Transthoracic Doppler echocardiography examinations and simultaneous laboratory tests for cardiac evaluation were performed on the sixth month after burn injury as well as with the control group. High-sensitivity C-reactive protein levels were significantly higher in the burn patients than in controls (5.17 ± 3.86 vs 2.42 ± 1.78; P = .001). Lateral isovolumic relaxation time was significantly higher in the burn injury group than in the control group (92.7 ± 15.7 vs 85.5 ± 8.3; P = .03). Baseline coronary diastolic peak flow velocity of the left anterior descending artery was similar in both groups. However, hyperemic diastolic peak flow velocity and coronary flow velocity reserve (2.26 ± 0.48 vs 2.94 ± 0.47; P < .001) were significantly lower in the burn injury group than in the control group. Coronary flow velocity reserve was significantly and inversely correlated with high-sensitivity C-reactive protein, burn ratio, creatinine, and mitral A-wave max velocity. At the sixth month of treatment, burn patients had high-sensitivity C-reactive protein levels during this period, suggesting that inflammation still exists. In addition, subclinical coronary microvascular and left ventricular diastolic dysfunction can occur in burn patients without traditional cardiovascular risk factors. However, these results must be supported by additional studies.

Evaluation of Demographic and Clinical Characteristics of Patients who Attempted Suicide by Self-Inflicted Burn Using Catalyzer.

Our aim was to assess demographic and clinical characteristics of patients treated at our units who attempted suicide by self-incineration, and to compare the results of burns with or without catalyzer use. Twenty patients who attempted suicide by self-incineration were examined in terms of clinical and demographic characteristics. Average age of the study population was 35 years (range 13-85 years). Average percentage of total body surface area burn was 53% (9%-100%). Six (30%) patients used gasoline and 5 (25%) used paint thinner in order to catalyze burning. Of these 11 patients who used a catalyzer, 5 (45.4%) had inhalation injury and 7 (63.6%) died. Among 9 patients who did not use any catalyzer, 1 (11.1%) had inhalation injury and 4 (44.4%) died. In general, inhalation injury was diagnosed in 6 patients (30%) while 11 (55%) patients died. A high morbidity and mortality rate was found in patients who used a catalyzer.

Giant fibroadenoma growing rapidly during pregnancy.

INTRODUCTION: Giant fibroadenoma is a rare disease with unknown etiology. During pregnancy, fibroadenomas increase in size and may show lactational histologic changes. High concentrations of estrogen, progesterone, and prolactin promote the ductal growth and formation of tubuloalveolar structures. This may be a reason for the significant enlargement in this period. CASE PRESENTATION: We presented a case of giant fibroadenoma, first detected at the onset of pregnancy, which grew rapidly and was excised surgically two months after the birth. There was no marked deformity in the breast nor a need to reconstruct it, despite the giant mass was excised and the mother was lactating. DISCUSSION: We presented a rare case of giant fibroadenoma in a lactating woman. A progressively growing mass in breast can lead to structural damages. The current management approach for giant fibroadenomas is still surgical excision.

Unusual findings in appendectomy specimens of adults: retrospective analyses of 1466 patients and a review of literature.

BACKGROUND: Diseases and tumors of the appendix vermiformis are very rare, except acute appendicitis. OBJECTIVES: This retrospective study was conducted to document the unusual findings in appendectomy specimens. PATIENTS AND METHODS: Data of 1466 adult patients were gathered retrospectively. Appendectomy was performed in 1169 and in 297 patients following a diagnosis of acute appendicitis and during other abdominal operations, respectively. The data of 57 (3.88 %) patients who were pathologically reported to have unusual appendix findings were retrospectively collected. The records were analyzed according to patients' age, gender, clinical presentations, operative reports, pathological reports and follow up. RESULTS: Unusual pathologic examination findings were detected in the appendectomy specimens of 57 patients with a mean age of 48.34 ± 19. Twenty-nine patients (50.8 %) were male and 28 (49.2 %) were female. Normal appendix tissues were observed in specimens of 26 (45.6 %) patients and inflamed appendix in 31 (54.3 %). The most common unusual finding was parasitic diseases of the intestine. Pathological diagnosis of malignancy and benign features were reported in specimens of 14 and 43 patients, respectively. Macroscopic evaluation of appendectomy specimens during surgery might result in negligence of the presence of unusual pathology. CONCLUSIONS: Even if the macroscopic appearance of the specimen is normal or acute appendicitis, we suggest routine histopathological examination.

Parasitic infections of the appendix as a cause of appendectomy in adult patients.

OBJECTIVE: Assessment of frequency and clinical findings of parasitic infections for etiology of acute appendicitis. METHODS: Data of 1452 patients who were carried out appendectomy between January 1999 and December 2012 were analyzed retrospectively. Appendectomy was performed in 1159 of the patients with a pre diagnosis of acute appendicitis. Demographics, physical findings, radiologic and laboratory studies, operative findings, pathological results, presence and type of parasitosis were investigated. RESULTS: Among the 1159 patients done appendectomy with a pre diagnosis of acute appendicitis, 719 (62%) were males and 440 (38%) were females. Parasitic infection was demonstrated in 17 (1.4%) of them. Mean average age of these patients was 36.6 ± 20.1 years. Enterobius vermicularis was present in 15 (88.2%) and Entamoeba histolytica in 2 (11.8%) of the patients. Of the pathology specimens of appendix consisting Enterobius vermicularis, 12 (80%) were normal appendix tissues, 1 (6.6%) was acute uncomplicated appendicitis and 2 (13.3%) were perforated appendicitis. One (50%) of the two specimens consisting Entamoeba histolytica was normal appendix and the other (50%) was acute appendicitis. CONCLUSION: Differential diagnosis of parasitic infections in etiology of acute appendicitis should be made properly. It must be remembered that this attention can save patients from a negative laparotomy and morbidity and mortality of it.

Effect of topical tetracycline on seroma formation in the Lichtenstein technique: a prospective randomized study.

We sought to investigate whether application of topical tetracycline has a limiting effect on seroma formation in patients undergoing hernia repair using a polypropylene mesh. This study was conducted in 96 patients undergoing an elective groin hernia repair. Patients were randomized and divided into 2 groups. After the graft was placed, and before external oblique muscle aponeurosis was closed, 5 mL tetracycline was administered on the graft in the tetracycline group (tetra group, n = 50), and 5 mL isotonic saline was administered in the control group (n = 46) without putting in a drain. Seroma checks via surface ultrasonography were done. Seroma amounts measured on the first day were significantly higher in the tetra group (P = 0.04). There were no significant differences regarding seroma measurements on the seventh day or in the first and second months. Topical tetracycline application has no limiting effect on seroma formation after a groin hernia operation.

A prospective clinical study of flow-mediated dilatation in burn injury.

The authors investigated endothelial function using flow-mediated dilatation (FMD) in burn patients. This study was done in burn patients with specific criteria on admission. Blood lipid profile at 1st day, high-sensitivity C-reactive protein, and FMD were assessed at 1st and 7th days, as well as at 1st and 3rd months. The highest values of high-sensitivity C-reactive protein were detected on the 7th day, which were significantly higher than those at 1st and 3rd months. The lowest value of FMD was observed on the 7th day. FMD values were higher during the 1st month compared with the 7th day. The highest value of FMD was detected in the 3rd month. It was found that FMD values measured at 7th day and 1st month were significantly lower in patients with a burn percentage of 40 or greater. Our results suggest that inflammation is more prominent on 7th day following burn. The decrease in FMD values on 7th day after injury can be attributed to endothelial damage. The increase in FMD on 3rd month after burn is attributable to effective burn treatment and gradual decrease of inflammatory mediators. The data from this study suggest that there is endothelial dysfunction and low-grade inflammation in burn patients. This condition is more prominent in patients with a burn ratio greater than 40%. Burn patients more frequently have impaired FMD, which may be indicative of arterial endothelial dysfunction and a marker for increased atherosclerosis.

Body mass index, cholecystitis, cholelithiasis, pancreatitis and imaging of common bile duct stones.

PURPOSE: Studies to date have not investigated whether body mass index (BMI) affects the sensitivity and specificity of magnetic resonance cholangiopancreatography (MRCP). The purpose of this study was to investigate the effect of BMI and also concomitant pancreatitis, cholecystitis and cholelithiasis on the sensitivity and specificity of MRCP. MATERIALS AND METHODS: Between January 2004 and December 2011, 185 patients were included in the study and divided into 3 groups according to BMI as normal, overweight or obese. Both MRCP and endoscopic retrograde cholangiopancreatography (ERCP) were performed in all patients. ERCP was accepted as the "gold standard." The accuracy, sensitivity and specificity values of the 3 groups were calculated to determine any effects on the results of the MRCP. RESULTS: Before separating into groups according to BMI, the statistical results for MRCP in the detection of stone disease were as follows: specificity 74.3%, sensitivity 81.7% and accuracy 79%. After dividing the patients into 3 groups according to BMI, the specificity of stone detection with MRCP in the normal-weight group was 93.8% but decreased to 65.5% in the overweight group and to 72% in the obese group. The sensitivity of stone detection with MRCP in the normal-weight group was 85.2% but decreased to 75% in the overweight group and increased to 88.9% in the obese group. The accuracy was 88.3% in the normal-weight group but decreased to 71.6% in the overweight group and to 81.9% in the obese group. CONCLUSION: Our study showed that MRCP performance was decreased in the overweight and obese groups.

Successful skin homografting from an identical twin in a severely burned patient.

Flame burns are a serious condition and usually have high morbidity and mortality because they affect large areas of the body surface as well as the lungs. In these patients, it is especially difficult to find healthy skin for grafting if they have more than 70% third-degree burns. Repeated autografting or synthetic wound care materials are the only treatment options to cover burned areas. Partial-thickness skin grafting from the patient's identical twin sibling may be an alternative treatment option, if possible. Here, we report a patient with severe flame injury treated with skin from his identical twin. The patient had third-degree burns covering 70% of his body surface. Initial treatment consisted of fluid and electrolyte replacement, daily wound care, and surgical debridements, as well as nutritional support. After initial treatment, we performed a successful skin grafting from his identical twin. Skin grafting between identical twins might be an alternate method for severely burned patients.
