RESUMO
BACKGROUND: Injury is one of the leading causes of death worldwide, and the abdomen is the most common area of trauma after the head and extremities. Abdominal injury is often divided into two categories: blunt and penetrating injuries. This study aims to determine the epidemiological and clinical characteristics of these two types of abdominal injuries in patients registered with the National Trauma Registry of Iran (NTRI). METHODS: This multicenter cross-sectional study was conducted with data from the NTRI from July 24, 2016, to May 21, 2023. All abdominal trauma patients defined by the International Classification of Diseases; 10th Revision (ICD-10) codes were enrolled in this study. The inclusion criteria were one of the following: hospital length of stay (LOS) of more than 24 h, fatal injuries, and trauma patients transferred from the ICU of other hospitals. RESULTS: Among 532 patients with abdominal injuries, 420 (78.9%) had a blunt injury, and 435 (81.7%) of the victims were men. The most injured organs in blunt trauma were the spleen, with 200 (47.6%) and the liver, with 171 (40.7%) cases, respectively. Also, the colon and small intestine, with 42 (37.5%) cases, had the highest number of injuries in penetrating injuries. Blood was transfused in 103 (23.5%) of blunt injured victims and 17 (15.2%) of penetrating traumas (p = 0.03). ICU admission was significantly varied between the two groups, with 266 (63.6%) patients in the blunt group and 47 (42%) in penetrating (p < 0.001). Negative laparotomies were 21 (28%) in penetrating trauma and only 11 (7.7%) in blunt group (p < 0.001). In the multiple logistic regression model after adjusting, ISS ≥ 16 increased the chance of ICU admission 3.13 times relative to the ISS 1-8 [OR: 3.13, 95% CI (1.56 to 6.28), P = 0.001]. Another predictor was NOM, which increased ICU chance 1.75 times more than OM [OR: 1.75, 95% CI (1.17 to 2.61), p = 0.006]. Additionally, GCS 3-8 had 5.43 times more ICU admission odds than the GCS 13-15 [OR:5.43, 95%CI (1.81 to 16.25), P = 0.002] respectively. CONCLUSION: This study found that the liver and spleen are mostly damaged in blunt injuries. Also, in most cases of penetrating injuries, the colon and small intestine had the highest frequency of injuries compared to other organs. Blunt abdominal injuries caused more blood transfusions and ICU admissions. Higher ISS, lower GCS, and NOM were predictors of ICU admission in abdominal injury victims.

BACKGROUND: Almost all cases of renal hydatid cysts need surgical intervention for treatment. We report a case of isolated renal hydatid cyst treated successfully only with medical therapy. CASE PRESENTATION: This case is a 79-year-old veterinarian presented with right flank pain, hydatiduria and positive echinococcus granulosus serology. A 70*50 mm cyst with daughter cysts in mid-portion of right kidney on presentation was changed into a 60*40 mm cyst without daughter cysts at last follow-up. Due to patient's refusal of surgery, our patient received medical treatment including praziquantel and albendazole. After completion of first round of treatment, recurrence occurred and the same treatment was repeated. At last, the cyst became inactive and calcified with negative serology and no clinical symptoms under medical treatment. CONCLUSION: The treatment of choice in renal hydatid cyst is surgery; although there are some reports about the efficacy of medical treatments for hydatid cysts but lower rates of recurrence and higher efficacy put surgery in a superior position compared to medical approaches. Our case showed relative success of medical treatment, despite the presence of a large multilocular renal involvement. Thus, medical therapy without surgery can be considered in very particular cases with isolated renal hydatid cysts.

Background: Patients with deep venous disease can be classified into two distinct categories: those with disease resulting from known deep vein thrombosis (DVT), which may subsequently lead to post-thrombotic syndrome (PTS), and those with disease caused by compressive factors or non-thrombotic iliac vein lesions (NIVL). The major factor causing the symptoms in patients with PTS and NIVL is venous hypertension which happens due to venous stenosis or venous obstruction. Nowadays Venous stenting offers a noninvasive approach for treatment of NIVL and PTS demonstrating high patency rate. Methods: We comprehensively reviewed relevant published papers from 2008 to 2023 that surveyed various influencing factors including the site of occlusion and etiology of occlusions, proper diagnostic imaging, ideal characteristics of venous stents, different dedicated venous stents, pre-operative, concomitant, and post-operative interventions and factors that challenge stenting in both PTS and NIVL patients. The papers were identified by searching the keywords "venous stenting", "PTS", "NIVL", "occlusion", and "stenosis" in PubMed central library MEDLINE and Google Scholar. Results: Patency rates, post-stent complications, and relevant data according to the patient's quality of life were included and analyzed from 476 identified studies. There is no validated protocol and guideline for using stents in patients with PTS and NIVL. Conclusion: As there is no validated protocol and guideline for using stents in patients with PTS and NIVL, our study may provide comprehensive information to assist researchers interested in writing the protocol and give them insight.
RESUMO
BACKGROUND: Colorectal cancer is one of the most common cancers and the leading cause of cancer-related deaths worldwide. The incidence is gradually increasing, and the mortality and recurrence rates of the disease remain high. METHODS: This study was conducted as a cross-sectional study using tissue samples of 106 patients who underwent surgery at Sina Hospital from 2021 to 2022. After histopathological examination and identification of the pathological features of the tumor, the samples were subjected to immunohistochemical staining using a monoclonal antibody against villin. RESULTS: In this study, we observed a significant association between villin expression and tumor depth, as well as a correlation between villin expression and tumor location (colon or rectum). However, no association was found between villin expression and the number of affected lymph nodes and age, sex, tumor grade, and size. Furthermore, there was no significant association between villin expression and tumor vascular or neural invasion. CONCLUSION: The extent of local invasion and metastasis are important factors in disease progression and can lead to treatment failure. Therefore, new biomarkers are needed to identify patients at risk of local and distant metastases and to enable appropriate treatment of patients.
RESUMO
BACKGROUND: SRY-related HMG-box 10 (SOX10) protein has a confirmed role in the regulation of neural cell proliferation and differentiation. It is now suggested that the changes in SOX10 expression may be linked to neural invasion by cancer cells. We aimed to assess the value of SOX10 expression in predicting perineural invasion in gastric cancer. METHODS: A cross-sectional study was performed on 40 patients with gastric cancer. To assess perineural invasion, Hematoxylin & Eosin stained slides were examined. The expression of SOX10 was also examined by immunohistochemistry. RESULTS: Our study showed higher perineural invasion in those with SOX10 positivity as compared to those without SOX10 expression (64.0% vs. 6.7%, p=0.001). No association was revealed between other baseline variables and SOX10 positivity. The expression of this marker increased the chance of neural invasion up to 17 times as indicated by the multivariable regression modeling. Multivariable regression modeling indicated that the chance of neural invasion increased up to 17 times in cases of SOX10 positivity. CONCLUSION: Overexpression of SOX10 is closely associated with the risk of perineural invasion in gastric cancer.

Introduction: The most common side effects were mild pain at the injection site and fever after the COVID-19 vaccination. A retroperitoneal abscess is a rare disorder with a deceptive onset and difficult diagnosis. It has various reasons and is related to a high mortality rate. Case presentation: A 29-year-old man with a recent history of first-dose Covid-19 vaccination, was referred for dyspnea, chest, and abdominal pain. Chest imaging revealed a lung abscess evacuated to pleural space. Left posterolateral thoracotomy surgery was done. Post-operation abdominopelvic imaging revealed increased fat stranding and fluid collection, suggesting retroperitoneal infection and abscess formation and the patient underwent drainage. Clinical discussion: Common side effects after COVID-19 vaccination were mild and expectable without hospitalization. But in our case, a rare complicated side effect was seen. Conclusion: Uncommon side effects should be observed to recognize whether they are related to the vaccine or not.
RESUMO
Finding 2 different histological tumor types at the same site is extremely unusual, especially in patients with no history of radiation exposure or a family history of cancer. We describe a rare case of co-occurrence of meningioma and squamous cell carcinoma at the same site. A 67-year-old woman with a 6-month headache and a verrucous ulcerative mass on her frontoparietal region is the subject of this case study. Her medical history and her family's medical history are both blank. Her bilateral frontoparietal regions were found to have large heterogeneous lesions with areas of necrosis and superficial ulceration on radiological examination. An extensive heterogeneous extra-axial lesion was discovered during further radiological analysis in the left parasagittal region. Histopathologic examination revealed an impinging tumor consisting of a meningioma and squamous cell carcinoma at the same site. It is extremely uncommon to have multiple primary scalp cancers of different cell types present at the same time. To identify these cancers and choose the best treatments, clinicians will benefit from the information in our case reports.
RESUMO
Key Clinical Message: The study reports a rare case of pelvic solitary fibrous tumor (SFT) that was initially considered as a peri-anal gastrointestinal stromal tumor due to similar radiologic/pathologic features. SFT diagnosis can be challenging due to its rarity and wide range of diagnoses that must be ruled out precisely. Abstract: Solitary fibrous tumors (SFTs) are rare tumors that can occur in any part of the body. Although usually benign, malignant SFTs have been reported, especially outside the lungs. Radiology can help with diagnosis, but immunohistochemistry is necessary to distinguish SFTs from other possible diagnoses such as gastrointestinal stromal tumors (GISTs). This study presents a rare case of pelvic SFT initially considered to be a peri-anal GIST, highlighting the importance of accurate diagnosis given the rarity of SFTs and the need to rule out other potential diagnoses.
RESUMO
INTRODUCTION: Calcifying odontogenic cysts (COC) are rare lesions classified as developmental cysts and occur mostly in the maxillary and mandibular bone. Some of the COCs are related to odontogenic lesions. CASE PRESENTATION: We report a 60-year-old man with COC of the maxillary bone, presenting after tooth extraction. The patient has a palpable tender mass at the right upper tooth area. Imaging shows a well-defined radiolucency in the 7-3 tooth area of the right upper jaw. The combination of radiologic data and histopathologic findings was in keeping with the calcifying odontogenic cyst. Total enucleation is the chosen treatment for COC. No recurrence is proved by X-ray imaging after 1-year follow-up. DISCUSSION: COC is a rare entity of odontogenic cysts and needs an exact diagnosis by pathology examination to estimate behavior. CONCLUSION: Our case report offers significant data that could help clinicians and surgeons as well as pathologists with the diagnosis and management of these lesions.
