This study was conducted to determine whether the presence and degree of left ventricular diastolic dysfunction (LVDD) can be predicted by the simple computed tomography -measured left atrial diameter (CTLAD). Methods Among adult patients who underwent both chest CT imaging and echocardiography in the emergency department from January 2020 to December 2021, a retrospective cross-sectional study enrolled patients in whom the time interval between the two tests was <24 hours. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic power of CTLAD for echocardiographic LVDD. Results In a study involving 373 patients, 192 (51.5%) had LVDD. Among them, 122 (63.5%) had grade 1, 61 (31.8%) had grade 2, and nine (4.7%) had ≥grade 3. Median CTLAD values were 4.1 cm for grade 1, 4.5 cm for grade 2, and 4.9 cm for ≥grade 3. The area under the ROC curve value of CTLAD in distinguishing ≥grade 1, ≥grade 2 (optimal cutoff ≥4.4 cm), and ≥grade 3 (optimal cutoff ≥4.5 cm) were 0.588, 0.657 (sensitivity, 61.4%; specificity, 66.0%, positive predictive value, 29.5%; negative predictive value, 88.1%; odds ratio, 3.1), and 0.834 (sensitivity, 88.9%; specificity, 70.1%; positive predictive value, 6.8%; negative predictive value, 99.6%, odds ratio, 18.7), respectively. Conclusion CTLAD ≥4.4 cm can be used as a rough reference value to distinguish LVDD of ≥grade 2, while CTLAD ≥4.5 cm can reliably distinguish LVDD of ≥grade 3. CTLAD might be a useful parameter for predicting LVDD in situations where echocardiography is not available.

Bisphosphonates inhibit bone resorption by affecting osteoclastic function and formation of osteoclasts from their precursor cells. Chondroclasts have the same origin and differentiation as osteoclasts. Thus, it is hypothesized that bisphosphonate can affect on cartilage metabolism. This study was aimed to elucidate effects of alendronate, a nitrogen containing bisphosphonate, on cartilage development in the tibial proximal and femoral distal epiphyseal plates in rats. Alendronate (1 mg/kg) was subcutaneously administered in growing rat pups for 10 days. Several parameters such as the number and size of chondroclasts, involved in cartilage resorption, size of secondary ossification center and thickness of cartilage cell layers were measured and analysed by histomorphometry. The size of the secondary ossification centers in the tibial proximal and femoral distal epiphysis was smaller in the alendronate treated group (p< 0.01). The number of osteoclasts in the both the ossification centers and chondroclasts beneath the epiphyseal plates was significantly decreased by alendronate treatment (p< 0.01). The size of chondroclasts was not significantly changed (p> 0.05). The thickness of proliferating cartilage layer was not changed, but by contrast, hypertrophied cartilage layer was increased in thickness by alendronate treatment. These findings suggest that bisphosphonates can affect cartilage cell metabolism in a chondroprotective way.

The impairment of host defense mechanisms, particularly of cellular immunity, causes high incidence of mycobacterial infections in the patients with ESRD. Extrapulmonary mycobacterial infections are more frequent in ESRD patients compared to general population. However, there has been rarely reported on the occurrence of hepatic tuberculous abscess as an extrapulmonary mycobacterial infection in ESRD patients. We present a case of ESRD patient manifesting miliary tuberculosis and hepatic tuberculous abscess, which have successfully resolved after anti-tuberculous medications. A 44 years old male admitted with fever, general weakness, night sweating, and cough. Chest X-ray and abdominal CT revealed pulmonary miliary tuberculosis and a solitary tuberculous abscess at S7 of right hepatic lobe with multiple periportal and celiac lymphadenopathy. After the administration of anti-tuberculous medications(isoniazid, rifampicin, ethambutol - eight month, pyrazinamide - two month), miliary tubuculosis disappeared. The size of hepatic tuberculous abscess and lymphadenopathy were reduced in abdominal CT six month later. The patient is followed in outpatient without noticeable symptoms after eight month treatment.

A bronchobiliary fistula (BBF), which is defined by an abnormal communication between the biliary system and the bronchial tree, is an uncommon complication after hemihepatectomy, trauma, hydatid disease, choledocholithiasis, and other causes of biliary obstruction. BBF are rare complication of hepatic resection that can present from days to years after operation. Management of fistula is often very difficult and can be associated with high morbidity and mortality rates. Early recognition and proper management are essential to avoid a fatal outcome. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic cholangiography (PTC) are the diagnostic studies of choice and offer the possibility of therapeutic intervention. Although large series in the literature emphasize the surgical management of BBF, the reoperative procedures tend to be complicated, with a significant morbidity and mortality. Nonsurgical intervention via ERCP or PTC are more recently notably successful when resolution of a distal biliary obstruction is accomplished. Only after aggressive attempts at nonoperative, interventional techniques have failed should operative approaches be entertained. We are reporting a case of BBF secondary to hepatic resection of hepatocellular carcinoma which was managed by surgical operation.
