Surgical Treatment of Extracranial Internal Carotid Artery Pseudoaneurysm in an Infant Due to Falling from Height: An Unusual Case.

Pseudoaneurysms of the internal carotid artery (ICA) caused by non-penetrating trauma are extremely rare. Patients with ICA pseudoaneurysms may present with cerebral ischemia, cervical masses, neck swelling, hematoma, rupture, pain, or cranial nerve dysfunction. We present a case of a left ICA pseudoaneurysm that developed in a 7-month-old infant because of a fall from height. The patient developed left-sided neck swelling that caused severe airway obstruction and respiratory arrest. The patient was urgently intubated and underwent emergency surgery under general anesthesia to repair the defect in the left ICA. Primary repair was performed to treat the pseudoaneurysms. The pseudoaneurysm sac was not removed because it was complicated and had extended into the respiratory tract. The patient was extubated on the 2nd day and discharged on the 7th day without complications. Follow-up of the patient after two weeks was unremarkable. Extracranial ICA pseudoaneurysms should be identified in patients presenting with blunt trauma. Emergency surgery should be considered for patients with progressive pseudoaneurysms.

Prognostic Value of Vertebral Bone Density in the CT Scans of Sepsis Patients Admitted to the Intensive Care Unit.

AIM: To evaluate the prognostic value of vertebral bone mineral density (BMD) and its relationship with mortality using the computed tomography (CT) scans of sepsis patients admitted to the intensive care unit. METHODS: In this retrospective study, patients diagnosed with sepsis at the intensive care unit between January and December 2022 were evaluated. Bone density was manually measured from the vertebral body using axial CT images. The relationship of clinical variables and patient outcomes with vertebral BMD, mortality, and mechanical ventilation was investigated. A lower BMD (osteoporosis) was defined as ≤100 HU. RESULTS: The study included 213 patients (95 females, 44.6%). The mean age of all patients was 60.1±18.7 years. At least one comorbidity was present in 64.7% (n=138) of the patients, and the most common comorbidity was hypertension (n=73, 34.2%). The mortality rate was 21.1% (n=45), and the mechanical ventilation rate was 17.4% (n=37), both being statistically significantly higher among the patients with a lower BMD (36.4 vs. 12.9%; p<0.001 and 29.7 vs. 10.8%; p=0.001, respectively). The rate of a lower BMD was significantly higher in the mortality group (59.5 vs. 29.5%; p=0.001). In the regression analysis, a lower BMD [odds ratio (OR), 2.785; 95% confidence interval (CI): 1.231-6.346, p=0.014] was a significant independent predictor of mortality. Interobserver agreement for BMD measurement was excellent, with an intraclass correlation coefficient of 0.919 (95% CI: 0.904-0.951). CONCLUSION: Vertebral BMD is a strong independent predictor of mortality and can be easily and reproducible evaluated on the thoracoabdominal CT images of patients admitted to the intensive care unit with a diagnosis of sepsis.

Percutaneous Treatment of Giant Hydatid Cysts and Cystobiliary Fistula Management.

RATIONALE AND OBJECTIVES: To investigate the efficacy and safety of percutaneous treatment in cystic echinococcosis (CE) type 1 and 3a giant cysts (with at least one diameter>10 cm) according to the World Health Organization classification and to evaluate the management of complications, especially cystobiliary fistulas (CBFs). MATERIALS AND METHODS: This retrospective study included 66 patients with 68 CE1 and CE3a giant cysts treated with percutaneous catheterization between January 2016 and December 2021. The characteristics of the cysts, major and minor complications, time to catheter removal, and length of hospital stay were recorded. RESULTS: Among the 68 cysts, CBFs occurred in 35 (51.5%), cavity infections in 11 (16.1%), recollection in five (7.4%), and anaphylaxis in three (4.5%). There was no mortality. Biliary drainage was observed intraoperatively in 20 (29.4%) and only postoperatively in 15 (22.1%) of the 35 cysts with CBFs. A plastic biliary stent was placed in 18 (51.5%) of the 35 cysts with CBFs. The patients with CBFs had a longer hospital stay and time to catheter removal than those without fistulas (15.3 ± 10.9 vs. 6.1 ± 2.6 days and 32.7 ± 51.8 vs. 6.2 ± 3.1 days, respectively; P < 0.001). Of the patients who developed recollection, three were treated with secondary catheterization, and two underwent surgery. In total, three patients underwent surgery. The rate of clinical success was 95.4%. All cysts were followed up for an average of 19.1 (range, 12-60) months, and there was an average 88.8% reduction in cyst volume compared to the initial evaluation. CONCLUSION: CE1 and CE3a giant cysts can be treated effectively and safely with high clinical success using the catheterization technique. Contrary to what has previously been reported for these patients, the rate of CBFs is high, but these patients can successfully be treated with percutaneous drainage and/or endoscopic retrograde cholangiopancreatography without the requirement of surgery.

Risk factors for the rupture of anterior communicating artery aneurysms: Coexistence of fetal-type posterior cerebral artery and A1 segment hypoplasia/agenesis.

PURPOSE: To investigate the effect of the coexistence of fetal-type posterior communicating artery (fPCA) and anterior cerebral artery (ACA) A1 segment agenesis/hypoplasia on the rupture of an anterior communicating artery (AComA) aneurysm. MATERIALS AND METHODS: A total of 216 patients consecutively presenting with AComA aneurysms between January 2014 and December 2021 on digital subtraction angiography were evaluated. Patients without three-dimensional rotational angiography images, those aged under 18 years, those with suspected mycotic aneurysms, and those with dissecting and giant aneurysms were excluded from the study. The aneurysms were divided into two groups as ruptured and non-ruptured. Hemodynamic filling patterns were classified into four different types. RESULTS: The study included 192 AComA aneurysms, 44.8% (n = 86) ruptured and 55.2% (n = 106) non-ruptured. According to hemodynamic filling patterns, in type 1, the frequency of non-ruptured aneurysms was statistically significantly higher than that of ruptured aneurysms (39.5% vs 18.9%; p = 0.001). In type 4, where fPCA and ACA A1 segment agenesis/hypoplasia coexists, the frequency of ruptured aneurysms was significantly higher than that of non-ruptured aneurysms (10.5% vs 22.7%; p = 0.026). The most common aneurysm size range was 4-7 mm (n = 85; 44.3%). There was no statistically significant difference in size between the ruptured and non-ruptured aneurysms (p = 0.627). CONCLUSION: According to the hemodynamic filling classification, we observed that the presence of type 4 filling pattern, i.e., the coexistence of ACA A1 segment agenesis/hypoplasia and fPCA, increased the risk of rupture in AComA aneurysms.

Tuberculous and non-tuberculous cervical lymphadenopathy incidence and distribution in Somalia from 2016 to 2020: A review of 241 cases.

Objective: To determine the incidence of tuberculous lymphadenitis (TBL) and other pathologies in cervical lymphadenopathies in Somalia and accompanying radiological findings. Methods: In this hospital-based retrospective study, the demographic characteristics, pathology results and radiological findings of 263 patients who underwent ultrasound (US)-guided cervical lymph node biopsy between January 2016 and February 2020 were analyzed. Results: Of 241 patients 118 men and 123 women (mean age 27.9 ± 18.1 years) included in the study, 46.1% (n = 111) were diagnosed as necrotizing granulomatous lymphadenitis (caseified, consistent with TBL) and 21.6% (n = 12, atypical lymphoid cells and n = 40, metastases) as malignancy. The most common type of metastasis was squamous cell cancer (n = 31), and the primary source of most of them was esophageal cancer (16/31, 51.6%). The age of patients with TBL was significantly lower than that of non-TBL (21.9 ± 14.6 vs. 41.9 ± 24.6, P = 0.003) and the incidence of TBL in pediatric patients was statistically higher (58.0% vs. 21.5%, P = 0.019). The rate of patients with TBL being localized at level 4 and level 5 was significantly more than non-TBL patients (18.0% vs. 10.0% and 23.4% vs. 10.8%, respectively, P = 0.01). Half of patients with TBL who have chest radiography had pathological findings; consolidation and bronchopneumonia were present in 52.6% of them. There were 2 patients with paravertebral abscess and one patient with gastrointestinal tuberculosis. Conclusion: In Somalia, in the presence of cervical lymphadenopathy, after diagnosis by using US-guided biopsy; primarily considering of TBL and malignancy, thoracic involvement should be investigated, and esophageal carcinoma must be excluded in terms of metastatic lymph node.

Exceptional Clinical Response to Surgery in Somalian Child Affected by Hyper Secretive Adrenal Cortical Carcinoma.

Adrenocortical cancers in childhood are very rare tumors. They are categorized as functional (hormone-secreting) or silent and as either benign or malignant. They have a bimodal distribution. Although in most adults they are non-functional, in the pediatric age group they may present as hormonal active or as an active tumor presenting with either virilizing forms or Cushing's syndrome or both sometimes. In children, due to the rapid development of symptoms, they come to attention early. However, if not diagnosed and treated early, they can develop into serious medical conditions. We present here a 6-year-old girl complaining of voice changes (deepening), extremely overweight, excessive hair growth over her body, and clitoromegaly for one year. Abdominal ultrasound and computed tomography revealed a well-defined adrenal mass with a slightly heterogeneous appearance and heterogeneous-contrast enhancement containing some necrotic areas. The patient was discharged one week after unilateral right adrenalectomy in good condition, and oral medications were given along with high-dose corticosteroid medications, which were reduced gradually. All the symptoms disappeared 6 months after the operation.

Magnetic resonance imaging findings of intracranial tuberculoma patients in a tertiary hospital in Mogadishu, Somalia: A retrospective study.

Introduction: Tuberculosis (TB) is a fatal disease caused by Mycobacterium tuberculosis (M.TB) with over eight million annual mortality reported worldwide attributed to the disease's direct or indirect effects. Among the most severe form of M. TB is an infection of the Central nervous system (CNS-TB). This infection is characterized by meningitis, tuberculoma, and tuberculous brain abscess. Tuberculomas are the most common variety of intracranial parenchymal tuberculosis. They occur because of conglomeration and conjugation of tubercular microgranulomas, which tend to occur at the grey-white matter junction due to the arrest of the hematogenous disseminating microbes caused by a decrease in the caliber of vessels in that region. Intracranial tuberculoma shows central hypointensity compared to grey matter, seeing this centrally on T2W images is helpful, as it is not seen in most other ring-enhancing lesions. Objectives: The purpose of this study was to evaluate the findings of the magnetic resonance imaging (MRI) scan of patients with intracranial tuberculoma using retrospective hospital records. Methodology: We conducted a retrospective data analysis of 73 patients with an age range of 3-70 years between 2018 and 2021 who were diagnosed with intracranial tuberculoma using MRI features at the Radiology Department, Somali-Turkey Recep Tayyip Erdogan Hospital. All the patients' MRI were evaluated, including conventional and contrast sequences and as well as MR diffusion. Results: This study revealed that most tuberculoma patients were female with 43 (58.9%) and 30 (41.1%) male. According to age group, the majority of patients 30 (41.1%) were 18-30 years of age. Based on the distribution of the conglomerates' tubercles, 39 (53.4%) were located in the supratentorial region, while 24 (32.9%) were found in both the supra-tentorial and infra-tentorial regions, with 10 (13.7%) residing in the infratentorial region. Interestingly, this study also discovered that the majority of the tuberculoma patients 43 (58.9%) had multifocal lesions, with 30 (41.1%) having single lesions. Also, associated abnormalities were detected in 28 (38.4%) of the patients with meningitis, while 7 (9.6%) had both hydrocephalus and meningitis, 2 (2.7%) had hydrocephalus, and one patient had cerebral infarction. Conclusion: The outcome of this investigation shows MRI as a suitable diagnostic tool for the diagnosis of intracranial tuberculoma and associated abnormalities in geographic areas where tuberculosis is endemic.

Can peritoneal thickening and enhancement be used to determine perforation in patients with acute appendicitis?

BACKGROUND: Acute appendicitis (AA) is a common cause of abdominal pain in developed countries. In patients with suspected AA, computed tomography (CT) is considered as the gold standard with the highest sensitivity and specificity, and it is also an im-portant modality, especially in patients with complicated AA. In this study, we aimed to evaluate age and laboratory findings, as well as specific CT findings in differentiating between perforated and non-perforated appendicitis. METHODS: We retrospectively analyzed 252 patients diagnosed with AA and underwent appendectomy between November 2015 and December 2019 in Somalia Mogadishu Recep Tayyip Erdogan Education and Research Hospital. Patients under 18 years of age and those with no pre-operative CT scans were excluded from the study. The demographic, laboratory, CT findings, and pathological data of all patients were evaluated. RESULTS: This study included 80 patients, 32 (40%) classified as perforated appendicitis (Group-1) and 48 (60%) as non-perforated appendicitis (Group-2). The C-reactive protein value was found to be statistically higher in Group-1 than in Group-2 (177.5±118.9 and 100.2±87.3 mg / L, respectively; p=0.001). The appendix lumen diameter (p=0.002), appendix wall defect (p<0.001), peritoneal thickening and enhancement (p<0.001), ascites (p=0.031), intra-abdominal abscess (p=0.003), jejunal thickening (p=0.019), ileal thick-ening (p=0.008), and ileus (p=0.035) values were significantly higher in Group-1. In the binominal logistic regression analysis performed with statistically significant data, an appendiceal wall defect (OR: 0.069, 95% CI=0.014-0.327, p=0.001) and peritoneal thickening and enhancement (OR: 0.131, 95% CI=0.024-0.714, p=0.019) were identified as independent variables for perforated appendicitis. CONCLUSION: Among CT findings, appendix wall defects and peritoneal thickening and enhancement play an important role in detecting perforation.

Thoracoabdominal injuries after a bomb explosion: blast injuries and their clinical effects.

PURPOSE: To report the types and effects of injuries to the thoracoabdominal region caused by blast and emphasize the importance of the early detection of primary blast injuries. METHODS: Of the 98 patients injured as a result of a bomb explosion, 31 with thoracoabdominal injuries were included in the study. The demographic and laboratory data, operations performed, and radiological findings were obtained from the electronic records of the patients. The injuries caused by the explosion were divided into four categories as primary, secondary, tertiary, and quaternary. The patients with a new injury severity score (NISS) of ≥ 16 were considered to have critical injuries. RESULTS: While mortality developed in 16 (51.6%) of 31 patients included in the study, 15 (48.4%) were discharged after treatment. The mean ages of the patients in the mortality and survivor groups were 29.6 ± 4.5 and 31.1 ± 10.7 years, respectively (p > 0.005). When the two groups were examined, the rate of hypovolemic shock and NISS score were significantly higher in the mortality group (p = 0.001 and p < 0.001, respectively) and the pH of the patients in the mortality group was more acidic (7.18 ± 0.13 vs. 7.34 ± 0.13, p = 0.002). One patient in the survivor group required surgery after the explosion due to missed primary blast injuries. CONCLUSIONS: To make the best use of resources in terrorist attacks and mass casualties that place a huge burden on health systems, it is important to evaluate patients with the highest index of suspicion for concealed blast injuries in terms of hospitalization and observation. In addition, health systems need to develop a cost-effective strategy considering the possibility of delayed-onset blast injuries.

The Prognostic Value of Vertebral Bone Density on Chest CT in Hospitalized COVID-19 Patients.

The aim of this study is to evaluate the prognostic value of the vertebral bone mineral density (BMD) on chest computed tomography (CT) in COVID-19 patients. The chest CT of hospitalized patients with COVID-19 pneumonia were evaluated for Pneumonia Severity Score (PSS) as the ratio of the volume of involved lung parenchyma to the total lung volume. In addition, BMD was manually measured from the vertebral corpus using axial CT images. The relationships of clinical variables, PSS and vertebral BMD with patient outcomes, namely mortality, intensive care unit (ICU) admission and mechanical ventilation were investigated. Lower BMD was defined as ≤100 HU. The study included 209 patients (118 males, 56.4%). As a result of the univariate analysis, the rates of mortality, ICU admission and mechanical ventilation were 17.2% (n = 36), 24.8% (n = 52), and 20.6% (n = 43), respectively, and they were significantly higher among the patients with lower BMD (38.1 vs 13.0%, p < 0.001; 33.4 vs 21.2%, p = 0.002; and 38.1 vs 8.2%, p < 0.001, respectively). In the mortality group, PSS was significantly higher (median, 9 vs 5; p < 0.001) and vertebral BMD was significantly lower (median, 83 vs 139; p < 0.001). Severe clinical incidence was significantly higher in patients with lower BMD compared to those with higher BMD (39.7 vs 24.7% and p = 0.028). There was a significant correlation between clinical classification and lower BMD (r = 0.152 and p = 0.028). The multivariate analysis revealed vertebral BMD [odds ratio (OR), 1.028; 95% CI, 1.011-1.045, p = 0.001) and lower BMD (OR, 4.682; 95% CI, 1.784-12.287, p = 0.002) as significant independent predictors of mortality. Vertebral BMD is a strong independent predictor of mortality that is reproducible and can be easily evaluated on the chest CT images of COVID-19 patients.

Imaging findings in patients after the bomb explosion in Somalia on December 28, 2019.

INTRODUCTION: This study aimed to present the radiological findings of injuries in victims as a result of a suicide bombing in Mogadishu, Somalia. METHODS: Of the 82 injured cases admitted to the emergency department within the first six hours after the explosion, those who were radiologically evaluated were included in this retrospective and descriptive study. To analyze and identify the distribution of primary, secondary, and tertiary injuries, they were classified according to the body areas as head-neck, thorax, abdominopelvic, extremity, and vertebra. RESULTS: The mean age (mean ± SD) of 63 patients included in the study was 28.6 ± 10.2 years. Twenty-four (38.1%) of the injured patients were female and 39 (61.9%) were male. Secondary blast injury was the most common type of injury in the study group with a rate of 39/63 (62%). The total number of bomb fragments was 235, of which 113 (47.8%) were seen in the head and neck region, followed by 86 (36.5%) in the extremities. There were 10 patients (15.9%) with lung injury and 13 (20.6%) with tympanic membrane perforation due to the primary blast mechanism. CONCLUSION: Radiological imaging plays an important role in identifying specific findings and patterns of explosive injuries. Therefore, we consider that patients with stable hemodynamics should be radiologically examined for a fast and accurate diagnosis or treatment.

Comparison of MRI and 18F-FDG PET/CT in the Liver Metastases of Gastrointestinal and Pancreaticobiliary Tumors.

OBJECTIVES: To compare the efficacy of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET/CT) and magnetic resonance imaging (MRI) in the detection of liver metastases originating from the gastrointestinal system (GIS) and the pancreaticobiliary (PB) system. METHODS: This retrospective study included 42 patients with primary GIS (stomach or colorectal) or PB system malignancies that metastasized to the liver, histopathologically confirmed diagnoses, and MRI and 18F-FDG PET/CT images. The MRI and 18F-FDG PET/CT images were analyzed. Student's t-test was used to compare the two modalities in terms of determining the number of metastases, and Cohen's kappa test was conducted to determine the agreement between the modalities. RESULTS: Twenty-eight (66.7%) of the patients included in this study were male, and the mean age was 60.67±9.4 years. Colon (n=25; 59.5%) and pancreatic (n=7; 16.6%) adenocarcinomas were the most common primary tumors that had metastasized to the liver. MRI detected more metastases in 12 (28.5%) patients, less in seven (16.6%), and an equal number of metastases in 23 (54.7%). No statistically significant difference was observed between the number of metastases detected by MRI and 18F-FDG PET/CT (7.55±7.96 and 6.36±7.28, respectively; p=0.11). There was a moderate agreement between the two modalities (kappa value=0.423). Most of the metastases detected on MRI but not seen on 18F-FDG PET/CT (n=10, 23.8%) were lesions smaller than 10 mm. For the eight (19%) patients with lymph node metastases, the number of metastatic lymph nodes detected by MRI and 18F-FDG PET/CT was similar (12 and 14, respectively, p>0.05). CONCLUSION: MRI can detect small lesions at an early stage, and 18F-FDG PET/CT shows the metabolic activity of lesions; therefore, the combined use of the two modalities can potentially offer a beneficial outcome for patients.

Ovarian Torsion Due to Mature Cystic Teratoma During the Early Postpartum Period: A Rare Case Report.

Mature cystic teratoma (MCT) is a benign and unilateral ovarian neoplasm usually seen in premenopausal women. Its most common complication, torsion, is a well-known cause of acute abdominal pain. However, it is rare in the early postpartum period. In this paper, we present a case of ovarian torsion due to MCT, which was diagnosed radiologically in the early postnatal period and surgically confirmed. A 25-year-old woman vaginally delivered a healthy baby on time and without any problems. She presented with acute abdominal pain in the right lower quadrant on the postpartum 5th day. Abdominal ultrasound (US) and computed tomography (CT) demonstrated an ovarian mass containing fat and calcification in the right adnexa and non-enhancing ovarian parenchyma. The patient was discharged on the 5th day after the salpingo-oophorectomy operation without any complications. US and CT provided crucial information to make an accurate and rapid management decision in ovarian torsion due to MCT.

Frequency of hepatic steatosis and its association with the pneumonia severity score on chest computed tomography in adult COVID-19 patients.

BACKGROUND: Recent studies of the coronavirus disease 2019 (COVID-19) demonstrated that obesity is significantly associated with increased disease severity, clinical outcome, and mortality. The association between hepatic steatosis, which frequently accompanies obesity, and the pneumonia severity score (PSS) evaluated on computed tomography (CT), and the prevalence of steatosis in patients with COVID-19 remains to be elucidated. AIM: To assess the frequency of hepatic steatosis in the chest CT of COVID-19 patients and its association with the PSS. METHODS: The chest CT images of 485 patients who were admitted to the emergency department with suspected COVID-19 were retrospectively evaluated. The patients were divided into two groups as COVID-19-positive [CT- and reverse transcriptase-polymerase chain reaction (RT-PCR)-positive] and controls (CT- and RT-PCR-negative). The CT images of both groups were evaluated for PSS as the ratio of the volume of involved lung parenchyma to the total lung volume. Hepatic steatosis was defined as a liver attenuation value of ≤ 40 Hounsfield units (HU). RESULTS: Of the 485 patients, 56.5% (n = 274) were defined as the COVID-19-positive group and 43.5% (n = 211) as the control group. The average age of the COVID-19-positive group was significantly higher than that of the control group (50.9 ± 10.9 years vs 40.4 ± 12.3 years, P < 0.001). The frequency of hepatic steatosis in the positive group was significantly higher compared with the control group (40.9% vs 19.4%, P < 0.001). The average hepatic attenuation values were significantly lower in the positive group compared with the control group (45.7 ± 11.4 HU vs 53.9 ± 15.9 HU, P < 0.001). Logistic regression analysis showed that after adjusting for age, hypertension, diabetes mellitus, overweight, and obesity there was almost a 2.2 times greater odds of hepatic steatosis in the COVID-19-positive group than in the controls (odds ratio 2.187; 95% confidence interval: 1.336-3.580, P < 0.001). CONCLUSION: The prevalence of hepatic steatosis was significantly higher in COVID-19 patients compared with controls after adjustment for age and comorbidities. This finding can be easily assessed on chest CT images.

Does COVID-19 cause an increase in spleen dimensions? Possible effects of immune activation, hematopoietic suppression and microthrombosis.

PURPOSE: To radiologically examine how the spleen size, which has important functions in hematological and immunological balance, is affected in COVID-19. METHODS: Between July 1 and August 31, 2020, consecutive patients diagnosed with COVID-19 were analyzed. Among these patients, those who underwent chest computed tomography (CT) examination at the time of presentation, patients with follow-up CT due to clinical deterioration were included in the study. The CTs of the patients were evaluated in terms of spleen size and volume. RESULTS: A total of 160 patients (88 females, 55%) were included in the study. The mean time between the initial and follow-up CT was 7.2 ± 2.8 days. The splenic volume (244.3 ± 136.7 vs. 303.5 ± 156.3 cm3) and splenic index (421.2 ± 235.5 vs. 523.2 ± 269.4 cm3) values were significantly higher in the follow-up CT compared to the initial CT (p < 0.001). The increase in the splenic volume and splenic index values was 59.2 ± 52.4 cm3 and 101.9 ± 90.3 cm3 (p < 0.001), respectively. The COVID-19 severity score was significantly higher in the follow-up CT compared to the initial CT (3.7 ± 4.2 vs. 12.5 ± 5.7, respectively; p < 0.001). The spleen width measured separately on the initial and follow-up CTs showed a highest positive correlation (r = 0.982, p < 0.001). CONCLUSION: Our study indicates that spleen size increases slightly-moderately in the first stages of the infection, and this increase is correlated with the COVID-19 severity score calculated on the chest CT data, and in this respect, it is similar to infections presenting with cytokine storm.

Bomb blast: imaging findings, treatment and clinical course of extremity traumas.

BACKGROUND: To describe the severity and types of blast-related extremity injuries and the presence of accompanying vascular injuries (VI) and amputation, and to identify the associated factors affecting the treatment management and clinical course. METHODS: The study included 101 patients with extremity injuries caused by a bomb explosion. The radiographs and computed tomography angiographies of the patients were evaluated in terms of injury patterns, presence of penetrating fragments and fractures, and localization (upper or lower extremity) and type (open or closed) of injury. The Gustilo-Anderson classification was used for open fractures. According to their severity, open fractures classified as types 1 and 2 were included in Group 1 and those classified as type 3A, 3B and 3C in Group 2. RESULTS: As a result of blast exposure, 101 (57.7%) patients had extremity injuries, of which 76 (75.2%) presented with at least one fracture. Of the total of 103 fractures, nine (8.8%) were closed and 94 (91.2%) were open. Thirty-eight (40.4%) of the open fractures were located in the upper extremities, and 56 (59.6%) in the lower extremities and pelvis. Open fractures were most frequently localized in the femur (n = 20; 21.2%), followed by the tibia (n = 18; 19.1%). The majority of patients with open fractures were in Group 1 (71.4%). The duration of hospital stay was longer in Group 2 (12.1 ± 5.8 vs. 6.3 ± 6.7 days, p <  0.0001, respectively). Mortality among patients in Group 2 (45.0%) was significantly higher than in Group 1 (8.0%) (p <  0.0001). Similarly, the injury severity score (ISS) was higher in Group 2 (median 20 vs. 9, p <  0.0001). VI was present in 13 (12.9%) of all patients, and amputation in seven (7.9%). CONCLUSION: The presence of severe open fractures, VI, and high ISS score can be considered as important factors that increase morbidity and mortality. In extremity traumas, through the secondary blast mechanism, contaminated-fragmented tissue injuries occur. Therefore, we believe that it will be beneficial to apply damage control surgery in places with low socioeconomic level and poor hygienic conditions.

The Effect of Hemodialysis on Axial Length, Ocular Surface, and Intraocular Pressure in Patients with End-Stage Renal Failure.

PURPOSE: To evaluate the changes in intraocular pressure (IOP), central corneal thickness (CCT), axial length, and ocular surface in patients with end-stage renal failure after single-session hemodialysis treatment and to examine the correlation of these findings with systemic hemodynamic parameters. PATIENTS AND METHODS: A total of 112 eyes of 112 patients enrolled in a hemodialysis treatment program for three times a week (approximately four hours per session) for at least three months in our hospital between December 2019 and March 2020 were included in the study. Approximately 30 minutes before and after hemodialysis, the best-corrected visual acuity measurement, slit-lamp examination, IOP measurement, and dilated fundus examination with the Goldmann applanation tonometer were performed in all patients. The axial length measurement was undertaken by ultrasonic biometry, and the CCT measurement by ultrasonic pachymetry. The ocular surface evaluation was performed based on the tear breakup time (BUT), basal secretion time (BST) and keratoepitheliopathy score. Blood pressure, serum osmolarity, and body weight were measured before and after hemodialysis. RESULTS: The mean IOP decreased from 12.2 ± 3.5 to 10.8 ± 2.2 mmHg, and the mean decrease was 1.4 ± 2 mmHg, indicating statistical significance (p<0.001). The mean CCT dropped from 502 ± 41.2 to 494.1 ± 35.4 µm, and the mean decrease was 8.1 ± 7.7 µm, which also indicated a statistically significant change (p<0.001). The mean axial length was reduced from 23.1 ± 0.8 to 22.9 ± 0.8 mm. The reduction in the axial length was significant with an average value of 0.26 ± 0.15 mm (p<0.001). When the ocular surface changes were examined, BUT decreased from 7.4 ± 3.1 to 6.3 ± 2.5 s, BST from 8.6 ± 1.7 to 6.6 ± 1.3 mm, and the keratoepitheliopathy score increased from 0.36 ± 0.61 to 1.59 ± 0.93, and all these changes were statistically significant (p<0.001). There was a significant correlation between the axial length change and the IOP change (r=0.202, p=0.03). A significant correlation was also observed between BST and plasma colloid osmotic pressure (r=-0.268, p=0.004). In addition, there was a strong correlation between serum osmolarity and the keratoepitheliopathy score (r=-0.437, p<0.001). CONCLUSION: Hemodialysis causes significant changes in IOP, CCT, axial length, and ocular surface. These changes should be considered in the ophthalmological examination of patients after the hemodialysis session.

Cancer Incidence and Distribution at a Tertiary Care Hospital in Somalia from 2017 to 2020: An Initial Report of 1306 Cases.

PURPOSE: To determine the type, frequency and distribution of all cancers in Somalia from 2017 to 2020. PATIENTS AND METHODS: This retrospective and descriptive study included the review of a total of 5238 pathology reports obtained from the medical records of the Somalia Turkey Recep Tayyip Erdogan Education and Research Hospital. Patient characteristics, lesion localization, and histopathology were recorded. Patients with an unconfirmed cancer diagnosis, borderline tumors, intraepithelial neoplasms and metastatic cancers were excluded from the study. The cases were classified according to gender, age, and organ involvement. RESULTS: Of the 1306 patients included in the study, 50.9% (n=666) were female and 49.1% (n=640) were male, and the mean age was 51.1±19.4 years. Of the cases, 5.1% (n=67) were pediatric (0-17 years) and 35.8% (n=468) were in the 18-50 years range. The most common cancer was esophageal cancer (EC) for the overall data (n=284; 21.7%) and in both genders. EC peaked in the fifth decade, and the most common histological type was squamous cell carcinoma (n=256; 91.1%). Liver cancer was the second most common cancer overall (n=99; 7.6%) and in men (n=67; 10.5%). Cervical cancer was the second most common cancer among women (n=88; 13.3%) and ranked fourth in terms of overall incidence (n=88; 6.7%). Breast cancer was the third most common overall (n=95; 7.3%) and in women (n= 87; 13.1%). CONCLUSION: This study shows that in Somalia, EC is the most common cancer in both genders. These high rates in Somalia suggest that environmental factors and dietary habits may have an effect. To reduce the incidence of EC and prevent its development, the population of Somalia should be educated and effective planning should be undertaken.

Assessment of Doppler flow parameters of the retrobulbar arteries and internal carotid artery in patients with glaucoma: the significance of ophthalmic artery peak ratio and the intima-media thickness of the internal carotid artery.

PURPOSE: The objective of this study was to analyze flow parameters of the central retinal artery (CRA), ophthalmic artery (OA), and internal carotid artery (ICA) assessed by color Doppler ultrasound. METHODS: Thirty-five patients with primary open-angle glaucoma (PAAG), 65 patients with normal-tension glaucoma (NTG), and 45 healthy controls, a total of 145 patients were included in this study and study participants were divided into three groups. All study participants underwent color Doppler ultrasound to assess blood flow parameters of CRA, OA and ICA. RESULTS: Comparisons among three groups revealed that pulsatility index and resistive index of the OA were significantly higher and peak ratio and end-systolic volume were significantly lower in patients with NTG or PAAG compared to healthy controls (p < 0.001 for all). As with OA, resistive index of the CRA was statistically significantly higher in patients with glaucoma (PAAG and NTG) compared to healthy controls (p < 0.001). The peak systolic volume and intima-media thickness of the ICA were statistically significantly higher in patients with PAAG compared to the other two groups (p < 0.001). ROC curve analysis of the CRA resistive index, OA resistive index and OA peak ratio in patients with glaucoma (PAAG and NTG) revealed that the sensitivity and specificity were 89% and 88%; 86% and 84%; 84% and 82%, respectively, at cutoff values of 0.64, 0.78 and 0.59, respectively. CONCLUSIONS: Ophthalmic artery peak ratio and ICA intima-media thickness may be useful parameters in the diagnosis of patients with glaucoma.

Doppler ultrasound diagnosis of brachial artery injury due to blunt trauma: A Case Report.

The brachial artery is the most common injured vessel in the upper extremity. Although vascular injury following blunt trauma is rare, it is a condition to be considered because it can easily be overlooked unless the clinician has a high suspicion. In this paper, we present a blunt trauma case with brachial arterial injury, upper extremity ischemia, and the need for urgent management to salvage the limb. A 28-year-old male had a right arm swelling, pain, and paleness accompanied by a weak pulse in the right radial artery and right-hand numbness. Following resuscitation, preoperative Doppler ultrasound revealed to the brachial artery injury. The right brachial artery had an occlusion with a thrombus. In spectral Doppler analysis, there were demonstrated parvus et tardus waveform in the distal arteries. Doppler ultrasound provided crucial information to make an accurate and rapid management decision.
