RESUMEN
INTRODUCTION: Breast reconstruction (BR) surgery is a widely utilized approach for women who have undergone mastectomy. Using synthetic mesh can offer advantages over other materials providing long-lasting support and natural-looking results. This study aims to compare the effectiveness of 3DMax™ mesh to TIGR mesh in BR surgery, providing clear information about the non-inferiority of 3DMax™ mesh to TIGR. METHODS: This retrospective cohort study evaluates postoperative complications in breast cancer patients who underwent subcutaneous mastectomy with direct-to-implant immediate BR using silicone implants and either 3DMax™ mesh or TIGR® Matrix Surgical Mesh. RESULTS: This study involved BR surgeries in 82 patients, including 57 surgeries in the 3D mesh group and 49 in the TIGR mesh group. The two groups had no significant differences regarding age, body mass index (BMI), cancer stage, or surgical complications. However, patients with neoadjuvant chemotherapy or radiotherapy had higher incidence rates of long-term complications than other patients. Patients with infection or partial necrosis had a heightened risk of implant loss. CONCLUSION: The clinical results obtained in this study suggest that among synthetic meshes used in immediate BR, 3DMax™ is not inferior to TIGR Matrix Surgical Mesh regarding complications.

INTRODUCTION: Mesh fixation in inguinal hernia repair, has been a controversial subject for many years. Therefore, in this study, we evaluated and compared fixation and non-fixation of mesh in Transabdominal Preperitoneal (TAPP) Inguinal hernia repair. METHODS: In this randomized control trial, 100 patients diagnosed with unilateral inguinal hernia were included. We divided the study population into two groups of fifty. For both groups, a 15 × 13 cm Prolene(polypropylene) mesh was used for repair. In the fixation group, mesh was fixed to the abdominal wall by endoscopic tacks, while in the non-fixation group, mesh was secured at the proper place without any fixation. Postoperative outcomes were complications, recurrence, and pain intensity after 1-, 3- and 6-months. RESULTS: Postoperative pain intensity in the 1st month [Median of 2 and 0, (P < 0.001)], and 3rd month [Median of 0.5 and 0, (P < 0.001)], in the fixation group were significantly higher than the non-fixation group. However, 6 months after surgery, pain intensity was almost similar for both groups. In the 6th postoperative month, only one patient experienced recurrence who was in the fixation group. The rate of recurrence and urinary retention between the groups was not significant. CONCLUSION: It was observed that until 6 months after surgery patients who received the non-fixating method of TAPP repair experienced lower levels of pain in comparison to the fixation group while other complications did not differ between the two groups.

BACKGROUND: In this study, we aim to evaluate the cosmetic outcome differences between Intraoperative electron beam radiation therapy (IOERT) and whole breast radiotherapy (WBR) with further investigation of boosted IOERT. METHODS: This retrospective cohort study was conducted in two referral centers in Tehran, Iran. 116 women aged 30 to 79 with early-stage breast cancer (T0-2N0-1M0) eligible for breast conservation were divided into two groups of 58 based on the intervention they received, and further subgroups were defined based on receiving boosted IOERT. Patients in both groups underwent breast conservation surgery and those in the IOERT group received either a 21 Gy radical dose (radical IOERT) or 12 Gy boosted electron beam radiotherapy and a routine fractionated dose of 50 Gy in 25 sessions of WBR (boosted IOERT). Those in the WBR group were administered 50Gy in 32 sessions. Physician-assessed cosmetic outcome was defined as the primary result and incidence of fat necrosis and fibrosis and post-operative chronic pain were secondary outcomes. RESULTS: Post-operative cosmetic outcome scores and chronic pain, showed no significant difference between the two groups. The median cosmetic score in both groups was 9. Fat necrosis and fibrosis had significantly higher rates in the IOERT group (P. VALUE: 0.001). However, the majority (21/34 or 61.8%) of this complication was observed in the boosted IOERT subgroup and no statistical significance was recorded between the radical IOERT subgroup and the WBR group. CONCLUSIONS: In early-stage breast cancer treatment, radical IOERT has noninferiority compared to WBR in terms of cosmesis. Regarding fat necrosis and fibrosis, boosted IOERT was associated with higher rates in comparison to other groups. Therefore, radical IOERT seems to be a better treatment option for selected patients.

BACKGROUND: Tracheal resection and anastomosis surgery is a safe operation and is used to treat various benign and malignant diseases of the trachea. However, tracheal stenosis is among the main anastomotic complications following this procedure. Surgeons use both the continuous and the interrupted suture techniques for tracheal anastomosis, but contradicting results in each technique's complications have been reported in various studies. In this study, we aimed to compare the outcome of these two different suture techniques and a relevant literature review. METHODS: Surgical records during a period of 15 years (2005-2019) were screened for tracheal reconstruction surgery in affiliated hospitals of Shiraz University of Medical Sciences, Shiraz, Iran. A total of 82 patients were evaluated based on surgical and suture features, along with their follow-up bronchoscopy for anastomotic complications. RESULTS: Post-operational subclinical restenosis occurred in 8 (15.3%) out of 52 and 10 (33.3%) of 30 patients who underwent continuous and interrupted suturing techniques, respectively. Also, 6 (20%) patients in the interrupted group developed symptomatic restenosis, while in the continuous group, only one patient was clinically symptomatic. The patients with continuous suture technique had a shorter surgery time than patients whose interrupted technique was used (P < 0.001). CONCLUSIONS: Based on our results, we conclude that restenosis is significantly reduced when the continuous technique is applied for tracheal anastomosis; However, the results are contradicting in relevant literature and due to the retrospective nature of our study, further human studies and clinical trials are warranted.

PURPOSE: The efficacy of intraperitoneal (IP) and incisional use of local anesthesia in laparoscopic cholecystectomy is a promising subject regarding post-operative pain control. In this study, we aim to compare these methods using lidocaine as the local anesthetic. METHODS: This study was a double-blinded randomized controlled trial. Eighty-two patients, candidates for laparoscopic cholecystectomy, were included. Participants were randomly divided into two equal groups; the instillation group and the infiltration group. In the instillation group, a 2% lidocaine ampule was instilled in the gallbladder bed after removal of the gallbladder. In the infiltration group, a 2% lidocaine ampule was injected subcutaneously into the port sites before making the incisions for the insertion of laparoscopic ports. RESULTS: The mean age of patients were 41.66 ± 14.44 and 48.05 ± 17.03 years in the instillation and infiltration groups, respectively. The etiologies recorded in this study were: acute calculous cholecystitis (29.3%), symptomatic gallstone (68.3%), and polyp (2.4). The pain severity, evaluated at six different times, from immediately after awakening from anesthesia to 24 h after the operation, was not significantly different between the two groups (p-value = 0.329). Consumption of nonsteroidal anti-inflammatory drugs and narcotics, were statistically lower in the instillation group (p-value = 0.013 and 0.003, respectively). However, hospitalization period, time spent to return to normal bowel movements and oral diet, and postoperative nausea/vomiting were not significantly significant between the groups. CONCLUSION: IP instillation of lidocaine following laparoscopic cholecystectomy offers post-operative pain relief and is associated with lower analgesic consumption in comparison to subcutaneous injection of this agent at the port site.

RESUMEN
BACKGROUND: Management and axillary staging of breast cancer has become less invasive and more conservative, over the decades. Considering Z011, axillary lymph node dissection (ALND) can be avoided in T1-2 N0-1 breast cancers with one or two positive sentinel lymph nodes (SLNs), if they are candidates for breast conserving surgery and radiotherapy. The aim of this study was to recognize if pre-operative axillary US evaluation in early-stage breast cancer could lead to more ALND in post Z011 era. METHOD: 463 breast cancer patients were evaluated. 368 early-stage breast cancer patients (T1-2 N0) were included. We did not perform axillary US in early stage clinically node negative patients; however, 97 patients had axillary US prior to our visit. If axillary US could detect more than two suspicious LNs, US guided biopsy was performed. The remaining clinically node negative patients underwent upfront SLNB. ALND was performed if more than two SLNs were metastatic, or US-guided ALN biopsy proved metastatic involvement. RESULTS: 97 patients had axillary US evaluation before the surgery. 67 patients (69.2%) did not have any suspicious US detected axillary LNs, 17 patients (17.5%) had one, 7 patients (7.2%) had two, and 6 patients (6.2%) had more than two suspicious LNs according to their axillary US evaluation. Those with more than two suspicious LNs underwent ALN US-guided biopsy. Metastatic involvement of the LNs was proved in all of them and they underwent upfront ALND. ALND revealed more than 2 metastatic LNs in 2/6 patients (33.3%). 91 patients who were evaluated by axillary US, had less than two US detected suspicious LNs and underwent SLNB. Amongst 24 patients with one or two US detected suspicious LNs, 1/24 patient had more than two positive SLNs and underwent ALND. In this group 15.6% underwent ALND and 5.2% of them were unnecessary according to the recent guidelines. Axillary US had a false positive rate of 36.6%. The sensitivity of axillary US in distinguishing patients with more than two suspicious LNs in clinically node negative patients was 25%. In the second group (without pre-operative axillary US evaluation), SLNB was performed. 204/272 patients (75%) did not have LN metastasis. 54/272 patients (19.9%) had one or two metastatic SLNs and according to Z011, ALND was omitted. 5.1% had more than two metastatic SLNs and underwent ALND. CONCLUSION: US evaluation of the axilla in early stage, clinically node negative breast cancer patients, is not sensitive enough to recognize more than two metastatic ALNs. It leads to more unnecessary ALND. Despite the small number of patients in this study, these results question the rationale of axillary US guided biopsy in low burden (less than two) suspicious LNs. looking for an imaging modality with a higher sensitivity in detecting the Burdon of axillary metastatic involvement is mandatory.

Burn injuries are among the most traumatic incidences which could be associated with substantial morbidity and mortality. The incidence of these injuries differs based on population socioeconomic characteristics. In this study, we aim to evaluate the distribution of burn injuries based on socioeconomic and causative factors. Relative features from the targeted population were obtained and evaluated. Data were extracted in August 2019 and statistical analysis of the data was conducted from February 2020 to April 2020. This cross-sectional record-based study was conducted from 2008 to 2016 in a main referral center for burn injuries in the southern Iran. Participants included burn survivors and burn patients who were registered as outpatients or inpatients. A total of 4919 burn cases with a mean age of 31.91 ± 17.33, including 2926 (59.5%) males and 1993 (40.5%) females was reported. The majority of our cases had an educational level of under diploma (40.72%). A significant correlation between age, gender, and percentage of burn with the level of education was recorded (P < .001). The most frequent cause of burn injuries was flame with 2537 (51.9%) cases. The most susceptible population to burn injuries were reported to be poorly educated individuals, which emphasizes the preventive role of education.

BACKGROUND: Self-immolation, as a method of suicide, is one of the most violent and extreme ways which is usually attempted by the ignition of inflammable materials, with more than 70% fatality rate. In the literature, Iran has been reported to have a high rate of self-immolation; therefore, this study aimed to evaluate the prevalence and epidemiological features of self-immolated patients. METHODS: In this retrospective cross-sectional multicenter study, data from burn patients from 2007 till 2017 due to self-immolation and suicide were enrolled in our study. RESULTS: Based on our data, 657 out of 3530 burn patients (18.6%) with a mean age of 31.15 (SD = 0.452) were documented as suicidal attempts; the majority were female (63.2%) and married (66.3%). Most of the patients were from rural areas (58.3%) with an education level of under diploma (63.2%). Of the patients in our study, 22 (8.7%) had comorbid systemic diseases and 115 (50.5%) had psychiatric disorders. CONCLUSION: Due to the high prevalence of suicide by self-immolation among the Iranian population, further studies to evaluate the risk factors and clarify the high-risk group for more targeted approaches are recommended.
