The present retrospective epidemiological study collected data on a sample of 710 newborns and compared the incidence of neonatal jaundice in infants born to Rh (D) negative and 0 Rh (D) positive mothers. The primary aim was to determine whether the higher incidence of maternal alloimmunisation in newborns was causally related to a potentially higher incidence of neonatal jaundice in newborns of 0 Rh (D) positive mothers. To the end, we investigated a possible association between the incidence of neonatal jaundice in 0 Rh (D) positive mothers and the neonatal blood group.

This self-limiting condition typically manifests as glandular swelling and pain, with variable severity, from hours to days post-contrast administration. Its etiology includes inflammatory edema, ductal obstruction, and pseudoallergic or idiosyncratic reactions. Non-ionic, low-osmolar agents such as Iohexol and Iodixanol are frequently implicated. Risk factors include iodine allergy, renal dysfunction, and inadequate premedication. Diagnostic imaging via CT or ultrasound reveals characteristic findings such as glandular enlargement, periglandular fat stranding, and heterogeneous enhancement, aiding differentiation from other causes like infection or neoplasms. This case series presents three patients who developed sialadenitis following contrast-enhanced CT scans. Presentations ranged from mild, localized submandibular swelling to rapid-onset bilateral glandular inflammation involving the parotid and submandibular glands. All cases highlight the need for prompt recognition and adherence to preventive measures, including premedication with corticosteroids and hydration, especially in high-risk patients. Management is largely supportive, involving corticosteroids, antihistamines, and NSAIDs, with severe cases requiring closer monitoring. By raising awareness of this underreported condition, this article underscores the importance of early recognition and differentiation from other conditions by radiologists, emphasizing their role in timely diagnosis and management.

We aimed to study the effect of fructose on the heart functions. Male HTG rats had HFI or a standard diet for five weeks. Heart function was tested ex vivo on the perfused heart using the Langendorff technique. Isolated hearts underwent 25 min ischemia (I) and 30 min reperfusion (R).

The LVDP showed a reduced return to the input values, the duration of VF in R increased, and the threshold for VF induction decreased. Serum TC, TAG, and kidney TBARS were increased.
