Morbidity and mortality associated with fracture of the sternum due to blunt trauma, by fracture type and location.

Objective: To examine the relationship that the types and locations of fractures of the sternum have with mortality and morbidity. Materials and Methods: We analyzed the records of 115 patients diagnosed with fracture of the sternum, due to blunt trauma, between 2007 and 2018. Records of computed tomography studies were obtained from the radiology archive of a tertiary teaching hospital. The type of fracture was classified as linear, displaced, or comminuted, whereas the fracture location was classified as the manubrium, body, or xiphoid process. Results: A total of 108 patients were included in the study. Of those patients, 92 (85.2%) were male and 16 (14.8%) were female. The etiology was a traffic accident in 72 cases (62.6%) and a fall from height in 36 (31.3%). The mean age was 42.1 ± 17.7 years for males and 53.9 ± 20.0 years for females. The mortality rate was 11.1%. Among the 12 deceased patients, the mean age was 44.4 ± 18.3 years. The fracture was located exclusively in the manubrium in 64 patients (59.3%), exclusively in the body of the sternum in 41 (38.0%), and in both locations in three (2.7%), whereas none were located in the xiphoid process. Morbidity rates were higher in the patients with fractures of the manubrium than in those with fractures of the body of the sternum, as was the incidence of accompanying bone fractures and organ injuries. The fracture was linear in 44 patients (40.7%), displaced in 62 (57.4%), and comminuted in 30 (27.8%). The mortality was significantly higher for comminuted fractures than for the other fracture types (p = 0.045; ß = 4.40). Conclusion: Fracture of the manubrium can be indicative of the severity of trauma and has a poor prognosis.

Materiais e Métodos: Foram analisados os prontuários de 115 pacientes com diagnóstico de fratura de esterno por trauma contuso entre 2007 e 2018. Os registros de estudos de tomografia computadorizada foram obtidos do arquivo de radiologia de um hospital universitário terciário. O tipo de fratura foi classificado como linear, deslocado ou cominutivo, enquanto o local da fratura foi classificado como no manúbrio, no corpo ou no processo xifoide. Resultados: Cento e oito pacientes foram incluídos no estudo. Desses, 92 (85,2%) eram do sexo masculino e 16 (14,8%) eram do sexo feminino. As causas foram acidente de trânsito em 72 casos (62,6%) e queda de altura em 36 (31,3%). A média de idade foi de 42,1 ± 17,7 anos para os homens e de 53,9 ± 20,0 anos para as mulheres. A taxa de mortalidade foi de 11,1%. Entre os 12 pacientes que faleceram, a média de idade foi de 44,4 ± 18,3 anos. A fratura localizou-se apenas no manúbrio em 64 pacientes (59,3%), somente no corpo do esterno em 41 (38,0%) e em ambas as localizações em três pacientes (2,7%), e nenhuma ocorreu no apêndice xifoide. As taxas de morbidade foram maiores nos pacientes com fraturas no manúbrio do que nos com fraturas no corpo do esterno, assim como a incidência de fraturas ósseas e lesões de órgãos adjacentes. A fratura foi linear em 44 pacientes (40,7%), deslocada em 62 (57,4%) e cominutiva em 30 (27,8%). A mortalidade foi significativamente maior nos casos de fraturas cominutivas do que em outros tipos de fratura (p = 0,045; ß = 4,40). Conclusão: A fratura do manúbrio pode ser um indicativo da gravidade do trauma e de mau prognóstico.

Utility of the Vidian Canal in Endoscopic Skull Base Surgery: Detailed Anatomy and Relationship to the Internal Carotid Artery.

OBJECTIVE: To investigate key anatomic features of the vidian canal that have a critical role in planning and performing endoscopic skull base surgeries. METHODS: We reviewed skull base computed tomographic images of 640 consecutive subjects. Studies were analyzed in axial, coronal and sagittal planes. RESULTS: The mean (±SD) length of the vidian canal was 15.4 ± 2.0 mm in female subjects and 16.6 ± 1.7 mm in male subjects, and the difference between genders was statistically significant (P < 0.001). The most common rostral-caudal course of the vidian canal was medial to lateral and was followed by the straight course, tortuous course, and lateral-to-medial course. The frequency of pneumatization pattern from most common to least common was types 0, III, II and I. Of 342 evaluated sides, the vidian canal was located below the level of the anterior genu of petrous ICA in 303 (89%) sides, at same level with the anterior genu of petrous ICA in twenty-five(7%) sides, and above the level of the anterior genu of petrous ICA in fourteen(4.1%) sides. CONCLUSIONS: A variety of previously undefined features of the vidian canal that can alter the course of surgical procedure were defined. The position of the vidian canal with respect to the petrous internal carotid artery (ICA) was extensively described. From a surgical standpoint, a working room inferior and medial to the vidian canal might not always be a safe approach, because the vidian canal could be located superior to the level of the anterior genu of petrous ICA according to our findings in the present study.

Variations in the vascular and biliary structures of the liver: a comprehensive anatomical study.

PURPOSE: Vascular structures of the liver and the bile ducts are crucial during liver transplantation or liver resection surgery. Here, we report on variations in the vascular structures and bile ducts of 200 patients. MATERIALS AND METHODS: We reviewed magnetic resonance cholangiopancreatographic and multiple-detector computed tomographic data. RESULTS: Michels type 1 was detected in 54% of the patients. The other most common variations were, respectively, Michels type 5 (13%) and type 2 (11%). Unclassified variations were defined as Michels type 11; 5% of patients were in this group. Type 1 variations in the hepatic portal vein were detected in 76% of our study group. Other common variations were type 2 (9%) and type 3 (8.5%). The left and intermediate hepatic veins united to become a single vein and then joined the inferior vena cava in 64% of the patients. The right, intermediate, and left hepatic veins joined the inferior vena cava separately in 36% of the patients. Type A, which represents the classic anatomy of the bile duct, was observed in 51.5% of our patients. Type C1 and type B were detected in 15% and 12% of patients, respectively. CONCLUSIONS: We describe vascular and biliary variations in the livers of our patients.

Evaluation of the multi-slice computed tomography outcomes in diaphragmatic injuries related to penetrating and blunt trauma.

PURPOSE: Traumatic diaphragmatic rupture is a diagnostic challenge for both surgeons and radiologists and generally occurs secondary to blunt and penetrating trauma of thoracoabdominal region. MATERIAL AND METHODS: 56 patients who underwent surgical procedure due to blunt or penetrating trauma were included to the study. RESULTS: There were 37 diaphragmatic ruptures in the left side and 19 patients in the right side. The most common radiological finding was "the direct monitoring of defect" (54,3%). CONCLUSION: Findings suggestive of diaphragmatic rupture must be carefully evaluated in patients with blunt or penetrating thoracoabdominal trauma.

An evaluation of preoperative computed tomography on patients with chronic otitis media.

This study aimed to compare the veracity of computed tomography findings on patients undergoing surgery for chronic otitis media (COM) with the surgical findings, and to determine to what extent the preoperative computerized tomography (CT) findings are useful to the surgeon. A series of 56 patients with COM undergoing preoperative CT scanning followed by surgical exploration of the middle ear and mastoid. Operative notes were recorded and data collected on the nature of soft tissue masses, the status of the ossicles, presence or absence of facial canal dehiscence and semicircular canal (SCC) dehiscence and the presence or absence of dural plate erosion, and sigmoid sinus thrombosis. Fifty-six patients were recruited in the study, 30 males and 26 females. The age range was from 16 to 67 years with a mean of 26.51 ± 1.4 years. The preoperative CT scan imaging in cases of cholesteatoma, ossicular chain erosion and SCC dehiscence have good correlation with the intraoperative findings. The specificity of preoperative CT scan in detecting facial canal dehiscence, dural plate erosion and sigmoid sinus thrombosis in patient of COM were weak. Preoperative computed tomography evaluation is fairly useful especially in cases of cholesteatoma. According to the results of this study, CT is of value particularly in the definition of cholesteatoma, and in determining ossicular chain erosion and semicircular canal fistula.

Quality of life, depression and anxiety in young male patients with silicosis due to denim sandblasting.

The aim of this study was to estimate the quality of life, depression and anxiety in patients with silicosis due to denim sandblasting. This study was conducted on 50 young male patients with silicosis and 30 controls. A socio-demographic data form, Short Form-36 (SF-36), the Beck depression inventory (BDI) and the Beck anxiety inventory (BAI) were used to determine quality of life, depression and anxiety. The mean scores of SF-36, BDI and BAI were higher in the patients than in the controls. Correlation analysis revealed a strong negative correlation between all scales of SF-36 and BDI scores. Additionally, there was strong negative correlation between five scales of SF-36 and BAI scores. We suggest that silicosis might be detrimental to the quality of life and increase depression and anxiety in patients with silicosis due to denim sandblasting.

The frequency of intracranial arterial fenestrations: a study with 64-detector CT-angiography.

Fenestration is a vascular variation that begins with a common origin, then splits into two parallel luminal channels and rejoins distally. Potential association between anomalies of cerebral circulation and increased occurrence of aneurysm makes intracranial arterial fenestrations important. The planning of intracranial arterial interventions may be complicated if a fenestration occurs proximal to the site of intended treatment. This study is planned to determine the frequency of fenestrations on CT angiography and to search whether there is relationship between aneurysms and fenestrations. CT angiographies of 395 consecutive patients, performed by 64-detector CT, were retrospectively reviewed for aneurysms and fenestrations. Overall fenestration frequency, fenestration frequency in patients with and without aneurysm, and aneurysm frequency in patients with and without fenestration were searched. Demographic characteristics of patients were also compared. Overall fenestration frequency was 12.9%. Vertebrobasilar system (5.56%) and anterior communicating region (5.32%) were the two most frequent sites of fenestration. The rate of fenestrations was not significantly different between patients who had and did not have aneurysms. Mean age was significantly higher, and females were predominant in patients with aneurysms. However our results did not show significant difference in age and sex of patients with fenestrations. The frequency of fenestrations in this study is higher than in previously published radiological studies, suggesting that fenestrations are relatively common. There is no significant relationship between the frequency of aneurysms and fenestrations.

Resection of intercostal hemangioma with involved chest wall and ribs: in an 11-year-old girl.

We report a case of an 11-year-old girl who presented with a slowly enlarging mass in the right posterolateral chest wall. Computed tomography showed a soft-tissue mass 8.5 × 7.5 × 5.5 cm in size, arising from the right posterolateral 9th, 10th, and 11th intercostal spaces. Magnetic resonance imaging confirmed a vascular mass. The patient underwent complete resection of the tumor, together with the right 8th, 9th, 10th, 11th, and 12th ribs and their intercostal muscles. Reconstruction of the chest wall was performed with methyl methacrylate and Marlex mesh. Histopathologic examination of the tumor confirmed an intercostal cavernous hemangioma. At last examination, 6 months after the operation, the child was doing well, with no evidence of recurrence.

[A rare cause of dysphagia: Forestier's disease]. / Disfajinin nadir bir nedeni: Forestier hastaligi.

Forestier's disease is a rare rheumatologic disease characterized by ossification in various spinal and extraspinal ligaments especially the anterior longitudinal ligament. The hypertrophic bone proliferations seen in cervical involvement may be so extensive causing dysphagia. We present Forestier's disease as a rare cause of dysphagia with clinical and radiological findings. An 80-year-old male was admitted for 2-3 months' increasing dysphagia and sore throat. Examination of the oropharynx revealed a 3 cm painless, hard swelling posterior to the epiglottis. A large area of ossification was detected in the anterior portion of the C2-7 vertebrae on lateral cervical roentgenogram. Neck computed tomography revealed bridging hyperosseous changes in the anterior longitudinal ligament between the C2-7 vertebrae and narrowing of the pharyngeal passage. A lesion with similar intensity to adjacent vertebrae and heterogeneous appearance lying along the anterior longitudinal ligament was seen on cervical magnetic resonance imaging. We interpreted the large osseous lesion to be an ossified anterior longitudinal ligament causing dysphagia, and a diagnosis of Forestier's disease was based on these findings. Forestier's disease must be kept in mind as a rare etiology in the differential diagnosis of dysphagia.

MDCT findings of denim-sandblasting-induced silicosis: a cross-sectional study.

BACKGROUND: Denim sandblasting is as a novel cause of silicosis in Turkey, with reports of a recent increase in cases and fatal outcomes. We aimed to describe the radiological features of patients exposed to silica during denim sandblasting and define factors related to the development of silicosis. METHODS: Sixty consecutive men with a history of exposure to silica during denim sandblasting were recruited. All CT examinations were performed using a 64-row multi-detector CT (MDCT). The nodules were qualitatively and semi-quantitatively analyzed by grading nodular profusion (NP) on CT images. RESULTS: Silicosis was diagnosed radiologically in 73.3% of patients (44 of 60). The latency period (the time between initial exposure and radiological imaging) and duration of silica exposure was longer in patients diagnosed with silicosis than in those without silicosis (p < 0.05). Nodules were present in all cases with centrilobular type as the commonest (63.6%). All cases of silicosis were clinically classified as accelerated and 11.4% had progressive massive fibrosis (PMF). Mild NP lesions were the most prevalent in all six zones of the lung. The NP score was significantly correlated with the duration of silica exposure, the latency period, presence of PMF, and pleural thickening. Enlarged lymphadenopathy was present in 45.5% of patients. CONCLUSIONS: The duration of exposure and the latency period are important for development of silicosis in denim sandblasters. MDCT is a useful tool in detecting findings of silicosis in workers who has silica exposure.

Evaluation of interlobar and accessory pulmonary fissures on 64-row MDCT.

We aimed to describe the prevalence, morphology, and completeness of the oblique, horizontal, and accessory fissures on 64-row multidetector computed tomography (MDCT) scans. Three hundred and eighty-seven patients were included in this study. The lungs were scanned from apex to diaphragm using 1-mm collimation. Images were evaluated on a Philips workstation using the PACS system. Prevalence of the interlobar and accessory fissures and also incompleteness of the interlobar fissures was evaluated on axial, coronal, and sagittal planes. The frequencies of right oblique fissures, right horizontal fissures, and left oblique fissures were 99.7%, 94.8%, and 100%, and the percentage of incompleteness was 69.7%, 86.9%, and 48.3%, respectively. Accessory fissures were detected in 164 of the 387 patients (42.4%). Pulmonary fissures are well visualized on MDCT because of its capacity in evaluating the whole thorax with thin sections and at various planes. Fast-image acquisition in MDCT also accounts for less motion artifacts and high-image quality.

Unusual presentation of eosinophilic fasciitis: two case reports and a review of the literature.

INTRODUCTION: Eosinophilic fasciitis is an uncommon disorder with unknown etiology and a poorly understood pathogenesis. We present the cases of two patients with eosinophilic fasciitis with unusual presentation, and describe the clinical characteristics and laboratory findings related to them. CASE PRESENTATION: The first case involves a 29-year-old Turkish man admitted with pain, edema and induration of his right-upper and left-lower limbs. Unilateral edema and stiffness with prominent pretibial edema was noted upon physical examination. A high eosinophil count was found on the peripheral smear. The second case involves a 63-year-old Turkish man who had pain, edema, erythema, and itching on his upper and lower extremities, which developed after strenuous physical activity. He had cervical lymphadenopathy and polyarthritis upon physical examination, and rheumatoid factor and antinuclear antibody upon laboratory examination. CONCLUSION: Eosinophilic fasciitis can present with various symptoms. When patients exhibit eosinophilia, arthralgia and myalgia, eosinophilic fasciitis should be considered as a possible diagnosis.

Effects of paramagnetic contrast agents on the gallbladder volume.

PURPOSE: Iodinated contrast agents lead to contraction of the gallbladder. The purpose of this prospective study was to investigate whether the paramagnetic contrast agents used for magnetic resonance imaging (MRI) cause volume changes in gallbladder or not. MATERIALS AND METHODS: The gallbladder volume changes were evaluated by ultrasound just before and 15 minutes after the imaging procedure in 10 patients without any paramagnetic contrast agent administration and 36 patients in whom paramagnetic contrast agents were administered during MRI. Gallbladder volume measurements before and 15 minutes after MRI were compared with each other. RESULTS: The mean pre- and post-procedural gallbladder volumes in patients on paramagnetic contrast agents were 30.2 +/- 19.3 cm(3) and 27.8 +/- 13.5 cm(3), respectively. They were 31.8 +/- 15.0 cm(3) and 29.5 +/- 9.3 cm(3), respectively, in patients who were not administered any paramagnetic contrast agent. There were no statistically significant difference between groups, regarding pre- and post-MRI gallbladder volumes. CONCLUSION: MRI, with or without paramagnetic contrast agents, does not lead to gallbladder volume contraction. In that regard, there appears to be no need to avoid ultrasound aimed to evaluate the gallbladder after MRI examinations.

Sheehan's syndrome and its impact on bone mineral density.

INTRODUCTION: Although there have been few studies investigating osteoporosis in isolated hormone deficiencies or other causes of hypopituitarism, the relationship between Sheehan's syndrome (SS) and osteoporosis has not been investigated. In the present study, we aimed to evaluate bone mineral density (BMD) in patients with SS in comparison with healthy women. METHODS: Sixty-one patients with SS and 62 matched healthy controls were included. Biochemical, hormonal assessments and BMD evaluations were carried out in patients and controls, and a subgroup analysis according to menopausal status was done (premenopausal < 50 years; postmenopausal > 50 years). RESULTS: The mean levels of serum anterior pituitary hormones were significantly lower in pre- and postmenopausal patients with SS compared with respective control groups (p < 0.0001). For both pre- and postmenopausal subjects, compared with respective controls, serum calcium and ALP levels, femur-T score, femur-Z score, spine (L1-L5)-T score, spine (L1-L5)-Z score and BMD values were lower, and phosphorus and parathyroid hormone (PTH) levels were higher in patients with SS. CONCLUSIONS: Patients with SS had low BMD. The possible mechanism responsible for osteoporosis may be hypogonadism, growth hormone deficiency and disorders of parathyroid hormone and calcium metabolism. But the contribution of each anterior pituitary hormone deficiency on bone loss should be clarified in further prospective studies.

An unusual cause of ileal perforation: report of a case and literature review.

An ileal perforation resulting from a migrated biliary stent is a rare complication of endoscopic stent placement for benign or malignant biliary tract disease. We describe the case of a 59-year-old woman with a history of abdominal surgery in which a migrated biliary stent resulted in an ileal perforation. Patients with comorbid abdominal pathologies, including colonic diverticuli, parastomal hernia, or abdominal hernia, may be at increased risk of perforation from migrated stents.

Diameters of normal thoracic vascular structures in pediatric patients.

PURPOSE: To determine the normal range of aortic and pulmonary artery diameters on chest CT, and to search a constant ratio when the diameters of thoracic vascular structures are compared with an internal reference. METHODS: Contrast-enhanced chest CT scans of 133 pediatric patients were retrospectively evaluated. Diameters of ascending and descending aorta, main pulmonary artery, right and left pulmonary arteries and a constant thoracic vertebra were measured. The mean ratios of thoracic vascular diameters to the diameter of the thoracic vertebra were calculated. RESULTS: There was a positive correlation between the age of the patients and vascular diameters. The mean ratios of vascular diameters to the diameter of thoracic vertebra, ranged from 1.1 for the ascending aorta to 0.70 for the right and left pulmonary arteries, were consistent. CONCLUSIONS: Diameters of thoracic vascular structures increase with age. The consistent vertebral to vessel ratios can be useful in evaluation of chest CT of pediatric patients.

Migration of ventriculoperitoneal shunt into the lung by passing through the liver and the diaphragm.

Thoracic complications are rare after shunt placement for drainage of cerebrospinal fluid to treat hydrocephalus. We report a case of a ventriculoperitoneal shunt catheter that migrated into the lung by passing through the liver and the diaphragm. To our knowledge, there is no previously published report of a ventriculoperitoneal shunt that has migrated into the lung by a transdiaphragmatic and transhepatic route.

64-MDCT pulmonary angiography and CT venography in the diagnosis of thromboembolic disease.

OBJECTIVE: The purpose of our study was to investigate whether CT venography (CTV) performed after CT pulmonary angiography (CTPA) using 64-MDCT provides additional findings in the diagnosis of thromboembolic disease. MATERIALS AND METHODS: Three hundred six consecutive patients in whom pulmonary embolism (PE) was clinically suspected were included in the study. The study group was classified according to the diagnostic quality of the CTPA examinations, the presence or absence of PE and deep venous thrombosis (DVT), and the most proximal localization that the embolus could lodge in the pulmonary artery. RESULTS: The diagnostic quality of CTPA was insufficient in 5.9%, acceptable in 8.2%, and excellent in 85.9% of the patients. The diagnostic quality of CTV was insufficient in 11.4%, acceptable in 47.4%, and excellent in 41.2%. The percentages of nondiagnostic examinations for CTPA and CTV were 5.2% and 10.8%, respectively. Acute PE and acute DVT were observed in 25.2% and 18.0%, respectively. The percentage of subsegmental emboli among patients with acute PE was 15.6%. The percentage of patients with thromboembolic disease was 29.1%. Of patients who were diagnosed as having thromboembolic disease, 13.5% (12 of 89 patients) had DVT only. Of all patients, 3.9% (12 of 306) had only isolated DVT. The number of patients with subsegmental PE who had DVT was two (0.7% all patients). CONCLUSION: As in MDCT scanning with a smaller number of slices, the combination of CTV with CTPA in 64-MDCT results in a small but definitive increase in the percentage of patients with a diagnosis of thromboembolic disease.
