Bedside measurement of the optic nerve sheath diameter with ultrasound in cerebrovascular disorders

Background/aim: We aimed to show the role of determination of optic nerve sheath diameter (ONSD) by bedside ultrasonography in an emergency department in the diagnosis of cerebrovascular disorders and its correlation with the clinical picture. Materials and methods: This prospective cross-sectional study included 55 patients with cerebrovascular disorders and 53 controls. Age, sex, ONSD, comorbid disease status, and multidetector computed tomography results of all subjects and application periods and National Institutes of Health Stroke Scale (NIHSS) scores of the patient group were evaluated. Results: The ONSD of the patient and control groups was determined as a median of 5.7 mm and 3.6 mm, respectively. The ONSD of the patient group was determined to be significantly higher than that of the control group (P < 0.05). A positive relationship was determined between NIHSS scores and ONSD values (P < 0.05). The specificity and sensitivity values were determined as 98.1% and 81.8%, respectively, for a cutoff value of 5 mm and as 100% and 72.7%, respectively, for a cutoff value of 6 mm. Conclusion: This study showed that bedside measurement of ONSD is an easy, cheap, and noninvasive method that can be used to support the diagnosis and evaluation of patients with acute stroke.

Verifying the Placement of Nasogastric Tubes at an Emergency Center: Comparison of Ultrasound with Chest Radiograph.

The objective of this study was to verify the nasogastric tube position with neck ultrasound and subxiphoid ultrasound, by giving air-water mixture and auscultation and to compare the effectiveness of these methods with chest radiography. This is a single-center, prospective, single-blind study. Patients who were admitted to our emergency department and had an indication of nasogastric tube placement were included. Nasogastric tube localization was verified with neck ultrasound and subxiphoid ultrasound, by giving air-water mixture, auscultation, and direct radiography that was accepted as the 'gold standard technique'. A total of 49 patients (27 Male, 22 Female) with a mean age of 58.3±22.7 years were included. Sensitivity of neck ultrasound was 91.5%, and positive predictive value was 100%. As for the subxiphoid ultrasound sensitivity was 78.72%. When neck ultrasound + subxiphoid ultrasound and giving water-air mixture were combined sensitivity reached 95.74%. Sensitivity of neck ultrasound + subxiphoid ultrasound + air-water mixture + auscultation was 97.87% and positive predictive value was 100%. In the light of our results, neck and subxiphoid ultrasound seem to be an alternative method for verifying nasogastric tube localization. Combination of the air-water mixture and auscultation with ultrasound improves the sensitivity.

Gastric outlet obstruction secondary to paraesophageal herniation of gastric antrum after laparoscopic fundoplication.

The most common causes of acute gastric outlet obstruction (GOO) are duodenal and type 3 gastric ulcers. However, mechanical or functional causes may also lead to this pathology. Acute GOO is characterized by delayed gastric emptying, anorexia, or nausea accompanied by vomiting. Herein we report a 56-year-old man diagnosed with GOO secondary to paraesophageal hiatal herniation of gastric antrum after laparoscopic fundoplication. Because of the rarity of this disease, common gastrointestinal complaints may mislead the emergency physician to diagnose a nonsurgical gastrointestinal disease if a detailed history and physical examinations are not obtained.

Rapid onset mediastinal hematoma due to vertebral fracture and review of relevant literature.

Patients with vertebral fractures are frequently encountered and those with thoracic and lumbar spine fractures are likely to have associated injuries. Detection of a widened mediastinum after trauma is very nonspecific and most of the time it is related to aortic injury or mediastinal hematoma. Vertebral or sternal fractures can also be the cause of mediastinal hematoma with or without aortic injury. This report reviews an unusual case of rapid onset mediastinal hematoma due to vertebral fracture after a fall. In the case, there was a mediastinal hematoma adjacent to a burst fracture of the T8 vertebral body. There was a rapid increase in identified hematoma during the emergency follow up and urgent erythrocyte transfusion was carried out. We would like to raise awareness of this infrequent presentation of mediastinal hematoma, as it is insidious and possibly fatal. In the evaluation of mediastinal hematoma, the detection of osseous injuries is a requirement.

Is it safe to be calcified? Porcelain gallbladder perforation and review of literature.

Calcification of the gallbladder wall (porcelain gallbladder) is an intense structure and uncommon manifestation seen in chronic cholecystitis and resulting from chronic inflammation of the gallbladder wall. Patients with porcelain gallbladder are usually considered not at risk of acute cholecystitis. However, sporadic cases of cholecystitis on porcelain gallbladder have been described in literature. Gallbladder perforation is a rare entity and may complicate on acute or chronic cholecystitis in a non-calcified gallbladder. We report an unusual case of acute cholecystitis with perforation in a porcelain gallbladder.

Short series of upper limb acute arterial occlusions in 4 different etiologies and review of literature.

Upper limb acute arterial occlusions are uncommon, and when compared with lower limb occlusions, only a few cases have been reported. Although atrial fibrillation is the most common cause, many conditions may lead to ischemia. In this article, 8 cases of upper limb arterial ischemia due to 4 different etiologies were reported (7 brachial, 1 axillary), and the literature was reviewed.

Spontaneous stone passage: is it Ammi visnaga effect?

Ammi visnaga was used in Ancient Egypt as an herbal remedy for renal colic. "Khellin", a chemical obtained from Ammi visnaga, was used as a smooth muscle relaxant and has been thought to have pleiotropic effects on urolithiasis. We report a case with multiple ureteral stone passages possibly as a result of medication with an herb preparation, Khellin.

Entire pneumorrhachis due to isolated head trauma.

Air contained within the spinal canal is termed pneumorrhachis, and very rarely, traumatic pneumocephalus can cause pneumorrhachis. Pneumorrhachis can be classified as epidural or subarachnoid space pneumorrhachis.

Plasma osteopontin levels are elevated in non-ST-segment elevation acute coronary syndromes.

BACKGROUND: The regions of ruptured atherosclerotic plaques have numerous macrophages. Osteopontin that modulates macrophage function has been shown in atherosclerotic plaques. We aimed to study the plasma levels of osteopontin in patients with unstable angina or non-ST-seg ment elevation myocardial infarction (NSTEMI) and the rela tionship between osteopontin and the extent of the coronary artery disease (CAD). METHODS: We studied 65 patients with unstable angina or NSTEMI, 25 patients with stable angina and 18 patients as the control group. The extent of coronary artery stenosis was determined by the number of vessels with >50% stenosis. Plasma osteopontin concentrations were measured from the blood samples that were drawn immediately after admission to the emergency department in unstable angina/NSTEMI patients and before the coronary angiograph in the stable angina and control groups. RESULTS: The plasma osteopontin concentration was (495 118 ng/ml) significantly higher in the patients with unstable angina/NSTEMI compared to the stable angina group (319 106 ng/ml) and control group (125+/-54 ng/ml) (p=0.0001 The plasma osteopontin levels were lower in the patients with stable angina pectoris who had one-vessel disease compared to those with two-vessel disease (p=0.01). How ever, in the unstable angina/NSTEMI group, the plasma osteopontin levels were statistically not different among the patients with one-vessel, and two-vessel and three-vessel disease (p=NS). There was no correlation between the plasma osteopontin levels and the extent of coronary stenosis. CONCLUSIONS: The plasma osteopontin levels are elevatedin patients with unstable angina/NSTEMI, but there appears to be no correlation with the extent of CAD. These results ma suggest that osteopontin may have a role in the pathobiology of ACS.

Plasma soluble osteopontin concentrations are increased in patients with rheumatic mitral stenosis and associated with the severity of mitral valve calcium.

Although the severity of valvular calcification is an important prognostic indicator, the cellular mechanisms of the calcification process are unknown. Osteopontin modulates inflammation and biomineralization, and increased osteopontin expression has been demonstrated in calcified degenerative or rheumatic cardiac valves. The present study evaluated soluble plasma osteopontin in 32 patients with echocardiographically determined rheumatic mitral stenosis and compared the results to those of a control group of 22 healthy patients. Patients were evaluated with routine echocardiographic techniques, Wilkins scoring, and 2-dimensional echocardiographic calcium scoring. Patients with rheumatic involvement other than in the mitral valve were excluded. Plasma osteopontin and high-sensitivity C-reactive protein levels in patients with mitral stenosis were significantly higher those of the control group (p = 0.006 and p = 0.0001, respectively). A significant correlation was found between plasma osteopontin levels and the severity of mitral valve calcification (p = 0.003) and also between high-sensitivity C-reactive protein levels and Wilkins score (p = 0.009). There was a stepwise and statistically significant increase in soluble plasma osteopontin levels in association with the severity of mitral valve calcification. In conclusion, increased osteopontin levels were correlated with the severity of mitral valve calcification in patients with rheumatic mitral stenosis, suggesting an important role of osteopontin in the modulation of valvular calcification. Elevated levels of high-sensitivity C-reactive protein concentrations suggest the presence of ongoing inflammation in those patients.

Increased soluble glycoprotein V concentration during the acute onset of unstable angina pectoris in association with chronic cigarette smoking.

Platelet hyperactivity is important in the pathobiology of acute coronary syndromes. Glycoprotein V (GPV) is an integral membrane protein of platelets in the function of the GPIb-V-IX receptor for vWf/shear-dependent platelet adhesion in arteries. Soluble GPV is a novel marker of platelet activation. The aim of this study is to assess circulating soluble GPV levels in unstable angina pectoris (UA). Twenty-one patients (15 men, six women, aged 52+/-7 years) with UA pectoris were studied. The inclusion criteria were angina at rest lasting >20 min during the preceding 6 h, with transient ST segment depression and/or T wave inversion and no evidence of myocardial infarction detected with the use of cardiac troponin-T. Coronary artery stenosis was angiographically confirmed in all patients. Twenty age- and sex-matched healthy adults (14 men, six women, aged 48+/-7 years) served as controls. There were no significant differences among the studied groups with respect to age, sex, obesity, smoking, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride and platelet counts. Plasma-soluble GPV concentrations were higher in the UA patient group (126+/-46 ng/ml) than those in the healthy controls (82+/-15 ng/ml) (P=0.001). There was a significant correlation only between plasma-soluble GPV levels and smoking (r=0.526, P=0.0001). Smoker UA patients had higher levels of soluble GPV than the non-smoker patients (139+/-40 vs. 113+/-50 ng/ml, respectively, P=0.02). However, soluble GPV levels were similar in smoker and non-smoker healthy controls (P=0.2). It is concluded that soluble GPV concentrations are significantly increased during the acute clinical course of unstable angina pectoris, indicating that soluble GPV may be useful marker of platelet activation in those patients. The level of the molecule is significantly affected from smoking in those patients.
