Splenic stiffness measured by 3-Tesla magnetic resonance elastography is correlated with age in healthy individuals.

OBJECTIVE: The aim of this study was to determine the splenic stiffness (SS) values in healthy individuals as measured by 3 Tesla magnetic resonance elastography (3T MRE) and to investigate the possible effects of parameters such as age, sex, spleen volume, diameter, and parenchyma thickness on SS. PATIENTS AND METHODS: This cross-sectional study was conducted in August 2023. A total of 54 healthy volunteers were included in this study. Participants' age and sex information were recorded, in addition to spleen craniocaudal and anteroposterior diameter, cortical thickness, spleen volume, and SS, which were measured using 3T magnetic resonance imaging and MRE. The relationships between SS and the other variables were investigated. RESULTS: Twenty-nine male and 25 female subjects with a mean age of 54.78 ± 15.40 years were included in the study. Mean craniocaudal diameter was 10.46 ± 1.16 cm, anteroposterior diameter was 9.88 ± 1.29 cm, parenchyma thickness was 4.08 ± 0.67 cm, SS was 3,721.94 ± 709.69 Pascal (Pa), and median spleen volume was 292.54 (239.40 - 311.00) cm3. A significant and strong positive correlation was observed between age and SS (r = 0.779, p < 0.001). The SS values were not associated with sex, craniocaudal diameter, anteroposterior diameter, parenchymal thickness, or volume. CONCLUSIONS: Age should be considered when using SS in the diagnosis and staging of relevant diseases such as portal hypertension and esophageal varices. Our results should be confirmed by future studies using 3T MRE in larger populations.

Gardner's syndrome: a case report.

Gardner's syndrome is characterised by polyposis coli associated with multiple hard and soft tissue tumours including osteoma and odontoma. The major significance of the condition lies in the gastrointestinal polyposis which usually undergoes malignant change by the fourth decade. Extra-intestinal components may be apparent before those in the bowel, and their early detection may lead to appropriate evaluation and life saving treatment. A case is reported to demonstrate how important it is for general dental practitioners to be aware of the clinical and radiological characteristics of Gardner's syndrome.

Polyorchidism: sonographic and magnetic resonance image findings.

Polyorchidism is a rare congenital anomaly frequently associated with maldescent testis, hernia, and torsion. Reports in the literature show an increased risk of testicular malignancy in the presence of polyorchidism. This entity has characteristic sonographic features and the diagnosis is often made on the basis of sonography. Magnetic resonance imaging might also be used for the diagnosis, but is more helpful in cases associated with cryptorchism or neoplasia. A conservative approach is the treatment of choice in uncomplicated cases.

The evaluation of 13 patients with intrathoracic extrapulmonary hydatidosis.

Cases of intrathoracic extrapulmonary hydatid cysts are very rare. We identified 13 patients with intrathoracic extrapulmonary hydatid cysts in our clinic over 12 years. Four patients had extrapulmonary cysts only; nine patients had both intrapulmonary and extrapulmonary cysts. Cysts were identified in the pleural space, extrapleural region, diaphragm and chest wall. Thoracotomy was used in all patients, and extrapulmonary lesions were removed by cyst extirpation from surrounding tissue or by pericystectomy. In one patient with chest wall involvement, partial rib resections were performed because of rib destruction. In two patients with liver cysts passing through the diaphragm to the thorax, the diaphragm was cut, cysts on the liver roof were removed and then the diaphragm was repaired. There was no mortality, morbidity, or disease recurrence during the post-operative period in any of the 13 patients. We conclude that these rare cases give a new insight into hydatid cyst pathophysiology.

White blood cell count and C-reactive protein predict short-term prognosis in acute myocardial infarction.

An elevated white blood cell (WBC) count and C-reactive protein (CRP) concentration are associated with acute myocardial infarction (AMI) and long-term mortality in patients with coronary artery disease. Their relationship with short-term prognosis following AMI is less clear, however. We investigated the relationship between WBC count and CRP concentration, obtained at the time of admission, and the development of subsequent ischaemic coronary events (SICE) within 30 days of AMI in 177 patients. After adjustment for confounding factors, CRP concentration was found to be a strong independent predictor for SICE within 30 days in patients with AMI. WBC count was not found to be an independent predictor, but there was a strong correlation between high WBC counts and the onset of SICE within 30 days in patients with AMI. We conclude that CRP concentration and WBC count could be used to predict the short-term prognosis of patients with AMI.

A retrospective comparison of bovine pericardium and polytetrafluoroethylene patch for closure of ventricular septal defects.

This retrospective study compared the immediate post-operative (first month) and mid-term (up to 5 years post-operation) results of 22 patients with isolated ventricular septal defects who underwent surgical correction with bovine pericardium with 57 similar patients who received a polytetrafluoroethylene (PTFE) patch. There were no cases of early (in the first month) mortality in either group and the 3-month post-operative echocardiographical studies showed no evidence of calcification or aneurysm formation around the patch. Recurrent ventricular septal defects due to dehiscence of the patch occurred in the early follow-up period in four patients who had the PTFE patch but this was not statistically significant. Annual echocardiographical examination revealed some calcification in both groups. We conclude that although there are no significant differences between the two materials in outcome after ventricular septal defects closure, we prefer bovine pericardium because of its handling characteristics, elasticity and the lower risk of endocarditis.

The effect of caudal bupivacaine versus tramadol in post-operative analgesia for paediatric patients.

In this study 20 paediatric surgical patients were randomized to two groups after induction of general anaesthesia. Group 1 received 0.25% bupivacaine (2 mg/kg) and group 2 received 5% tramadol (2 mg/kg) both as a caudal block. Heart rate, mean arterial pressure, arterial oxygen saturation, respiratory rate and pain and sedation scores were recorded at 1, 2, 4, 6, 12 and 24 h post-operatively. Acetaminophen was administered rectally (20 mg/kg) if the pain score was > 3/10. The pain and sedation scores in group 2 were significantly lower compared with group 1. There were no significant differences in heart rate, mean arterial pressure, arterial oxygen saturation and respiratory rate between the two groups. In conclusion, caudal tramadol was superior to bupivacaine in analgesic efficacy and in reducing the need for additional analgesia during the post-operative period in paediatric patients.

Radiology of an atypical fibro-osseous lesion confined to the nasal cavity.

Fibro-osseous lesions of the sinonasal region are relatively frequent, but those strictly confined to the nasal cavity are rare. We report an atypical fibro-osseous lesion in the nasal cavity and describe its radiological features. The differential diagnosis is discussed.
