RESUMO

PURPOSE: Diabetes mellitus (DM) plays a key role in the formation and prognosis of cardiovascular diseases. In this study, we aimed to investigate the effects of DM and glycemic control on left internal thoracic artery (LITA) Doppler flow in patients scheduled to undergo coronary artery bypass graft (CABG) surgery. METHODS: Patients who were hospitalized with a planned isolated CABG operation to our clinic between October 1, 2019 and March 1, 2020 were consecutively included in this prospective study. The patients were divided into three groups as those without DM (Group 1), those with DM and HbA1c values of below 7.5 (Group 2), and those with DM and HbA1c values of 7.5 and above (Group 3). The differences between the LITA Doppler flow patterns of the patients were analyzed. RESULTS: The mean ages of Group 1 (n = 103), Group 2 (n = 42), and Group 3 (n = 47) were 59.8 ± 9.6 years, 60.5 ± 9.3 years, and 61.9 ± 8.1 years, respectively. The groups differed in terms of diameter, volume, Vmax, pulsality index (PI), and resistive index (RI) values, both when the groups were compared among themselves (P < .001, for all), and when they were compared between those with (Groups 2 and 3) and without DM (Group 1) (P < .001, for all). Volume (R = -0.627, P < .001) and Vmax (R = -.450, P < .001) were moderately negatively correlated, while PI (R = .523, P < .001) and RI (R = 0.598, P < 0.001) were moderately positively correlated with HbA1c levels. CONCLUSION: In this study, we showed that increased HbA1c levels may be associated with significant functional and structural changes of LITA.

RESUMO

SUMMARY OBJECTIVE: Many laboratory parameters allow to follow up the course of the disease and reveal its clinical severity, particularly in patients with coronavirus disease 2019 (COVID-19) pneumonia. In this study, we aimed to investigate the role of the blood urea nitrogen-to-albumin ratio in predicting the mortality in COVID-19 patients with moderate-to-severe disease who are hospitalized in the intensive care unit. METHODS: A total of 358 patients who were hospitalized in intensive care unit at our hospital between November 1, 2020 and May 15, 2021 were included in this study. During their course of intensive care, surviving patients were included in Group 1 and nonsurviving patients in Group 2. RESULTS: There were no statistically significant differences between the two groups in terms of gender, smoking, and chronic obstructive pulmonary disease rates. In multivariate logistic regression analysis, advanced age (OR 1.038, 95%CI 1.014-1.064, p=0.002), neutrophil-to-lymphocyte ratio (OR 1.226, 95%CI 1.020-1.475, p=0.030), blood urea nitrogen-to-albumin ratio (OR 2.693, 95%CI 2.019-3.593, p<0.001), and chest computed tomography severity score (OR 1.163, 95%CI 1.105-1.225, p<0.001) values were determined as independent predictors for in-hospital mortality. CONCLUSION: In this study, we showed that the blood urea nitrogen-to-albumin ratio, which was previously shown as a predictor of mortality in patients with various pneumonia, was an independent predictor of mortality in patients with COVID-19 pneumonia.

RESUMO

OBJECTIVE: The aim of this study is to find out if it is possible to differentiate between brucellar and non-specific epididymorchitis by comparing ultrasonography (US) and color Doppler ultrasonography (CDUS) findings. MATERIAL AND METHODS: Fifty-six patients diagnosed to have epididymorchitis both clinically and ultrasonographically were included to study. All of the patients were investigated serologically for brucella. Twenty-eight of those patients were admitted brucella epididymorchitis because of high agglutinations titers for brucella. The other 28 patients were admitted non-specific epididymorchitis because of normal agglutinations titers for brucella. Testicular size, echogenicity, hydrocele, internal echoes and/or septations within hydrocele, and scrotal skin thickness of normal and involved testis were compared by ultrasonography. Besides, pick systolic velocity, end diastolic velocity, resistive index and pick systolic velocity ratio values were measured by bilateral testicular color Doppler ultrasonography in both groups. When the p-value is <0.05, the difference between groups is accepted as statistically significant. RESULTS: Thickening of scrotal skin was seen in 17 of 28 patients with brucella epididymorchitis (BEPO) (67%) and in 25 of 28 patients with non-specific epididymorchitis (NEPO) (89.2%) (p < 0.01). There was no difference between groups regarding presence of hydrocele. However hydrocele seen in all patients was anechoic except for two patients (8.6%). Hydrocele seen in 18 of 22 patients with BEPO and hydrocele had internal echogenicity or septation (p < 0.001). Sizes of testes and epididymis were found to be increased in involved testis compared to normal testis. Testes of all patients with NEPO were homogenous with decreased echogenicity except for five patients (17.8%). However, 23 patients with BEPO (82%) found to have heterogenous testis (p < 0.001). Spectral measurements showed increased PSV and EDV values and decreased RI values in involved sides in both groups. There was statistical significant difference in respect to maximum and minimum flow velocity between two groups (p < 0.05). There was no difference between the two groups regarding RI values. PSV ratio was 3.1+/-1.3 in patients with BEPO and 2.2+/-0.7 in patients with NEPO. CONCLUSION: Heterogenicity, focal echogenicity differences and hydrocele with granularity and/or septation seen in a patient presenting with scrotal infection in brucella endemic areas must rise the possibility of brucellosis rather than NEPO. By this way, effective treatment can commence immediately and complications can be avoided.

RESUMO

OBJECTIVE: The objective of this work was to determine the incidence and radiologic appearance of pneumatized inferior turbinates (PITs). METHODS: Pneumatized inferior turbinates were investigated among 2500 consecutive cases with coronal paranasal sinus computed tomography (CT) scans that were performed for different reasons between 2000 and 2004. RESULTS: Ten new PIT cases diagnosed with CT were identified. Pneumatization was diagnosed in 2 patients aged 7 and 14 years. Therefore, this is the first time that PIT has been described in the pediatric age group. Complete or incomplete pneumatizations were unilateral in 7 cases and bilateral in 3 cases. In bilateral PIT cases, pneumatizations were asymmetric. In 2 cases, only bulbous parts of the inferior turbinates (ITs) were involved. Inferior turbinate expansion related to pneumatization was not observed in any case. In cases with maxillary sinus communication, axial CT sections revealed a defect on the medial wall of the maxillary sinus. CONCLUSIONS: The incidence of PIT was found to be 1 in 250 cases. It is suggested that most PIT cases may be a result of articulation defects between the maxillary process of the palatine bone and the maxillary bone. In such a situation, the maxillary process of the palatine bone and the nasal process of the maxillary bone, which form the medial wall of the maxillary sinus at the IT level, can attach to the IT separately.

RESUMO

Placental chorioangioma is the most common benign tumor of placenta, encountered in approximately 1% of all pregnancies. Clinical manifestations are rare and usually associated with tumors greater than 5 cm in diameter. They include polyhydramnios, congestive heart failure, anemia, prematurity, growth retardation, and intrauterine fetal death. We report a case of chorioangioma of the placenta in which ultrasonography and Doppler ultrasonography findings were useful in establishing the prenatal diagnosis.
