Fibrillary and immunotactoid glomerulonephritis are infrequent causes of primary nephrotic range proteinuria and are poorly understood. Recent significant developments include the discovery of DNA JB9 antigen in fibrillary glomerulonephritis. Here, we present a case of a middle-aged woman who presented with nephrotic range proteinuria, hematuria, and normal renal function. Renal biopsy revealed fibrils that were randomly arranged on electron microscopy. They were of small size and congo red negative similar to the ones found in fibrillary glomerulonephritis, but were also DNA JB 9 negative, and had a hollow core like in immunotactoid glomerulopathy. Though we try to classify these conditions into either immunotactoid glomerulonephropathy (ITGN) or fibrillary glomerulonephritis (FGN), there are scenarios such as this case where it does not fit into either and is probably an overlap or intermediate variant of these two conditions. Pathological features of these glomerulonephrites are discussed together with their clinical implications, treatment choices, and diagnostic importance.

Background: Lisdexamfetamine has not heretofore been reported to cause pathological gambling. Such a case is presented. Methods: A middle-aged woman, without past interest in gambling, gaming, or risk taking behavior, with childhood history of attention deficit hyperactivity disorder presented with difficulty focusing and concentrating. Lisdexamfetamine was started at 20 mg daily and gradually escalated due to lack of efficacy. At 70 mg daily, she began binging on sweets and gambling all day, every day at nearby riverboats, which she had never frequented previously. Upon reduction to 60 mg daily, the gambling resolved. Ritalin 20 mg every morning and 50 mg every afternoon was used without gambling reoccurrence. Results: Mental Status Examination: Alert, cooperative and oriented x 3 with good eye contact. Euthymic, without mania, thoughts logical and goal directed. Conclusions: Enhanced dopamine in the nucleus accumbens may induce hedonic activities including gambling, binging on sweets, or sexual activity (Moore et al. 2014). Lisdexamfetamine has been described to induce mania, and pathological gambling may have been an isolated manifestation of early mania. In those who have recently begun lisdexamfetamine, query should be made regarding change in gambling behavior and in those who are pathologically gambling, investigation should be entertained as to whether they are taking lisdexamfetamine.

Abstract Objectives Statins have proved to reduce cardiovascular morbidity and mortality in high-risk population and are generally well tolerated, although adverse events can occur. Up to 3% of patients develop aminotransferases elevation, which usually normalizes with continued treatment and hardly is associated with clinical symptoms. Serious statin-related liver injury is exceedingly rare. Furthermore, literature regarding rechallenge with a second statin is extremely poor. Some authors caution that re-exposure to these drugs is associated with a more serious liver injury but safe switching to a second statin after drug-induced liver injury (DILI) is also reported. Case presentation We describe a case of a middle-aged woman who developed hepatocellular liver injury after simvastatin dose escalation; a rechallenge with low dose rosuvastatin caused rapid recurrence of DILI. Conclusions In our opinion, clinicians should be very cautious upon rechallenge and closely follow-up patients who experienced statin-induced liver injury when trying re-exposure to another statin.
