Different Management Options for Transplant Ureteral Obstructions within an Inguinal Hernia.

Ureteral obstruction secondary to an inguinal hernia with transplant ureteral component is an extremely rare entity with only several case reports found in literature. In all previously reported cases, management of the obstruction involved temporary drainage with ureteral stenting or nephrostomy tube placements followed by delayed definitive repair. We present two case reports, here one being the first one managed by immediate definitive repair via ureteral reimplant and herniorrhaphy and a second case by delayed definitive repair after percutaneous nephrostomy tube placement. Both patients continued to do well postoperatively with normalization of renal function on follow-up.

Safety and tolerability of high-dosage coenzyme Q10 in Huntington's disease and healthy subjects.

Coenzyme Q10 (CoQ(10)), a potential neuroprotective compound, was previously investigated at a dosage of 600 mg/day in Huntington's disease (HD) patients and demonstrated a trend toward slowing disease progression. Higher CoQ(10) dosages may prove beneficial. We investigated the tolerability and blood levels associated with 1,200, 2,400, and 3,600 mg/day of CoQ(10) in HD and healthy subjects. Twenty-eight subjects (20 HD, 8 healthy) enrolled in a 20-week open-label trial. Subjects started on 1,200 mg/day of CoQ(10), increasing every 4 weeks by 1,200 mg to a maximum dosage of 3,600 mg/day. Monthly evaluations included review of adverse events and CoQ(10) blood levels. Twenty-three subjects (82%) achieved the target dosage of 3,600 mg/day. Six subjects (2 healthy, 4 HD) withdrew prematurely (gastrointestinal (GI) symptoms in 3, worsening HD in 2, and 1 because of a fall). All three serious adverse events occurred in a single subject, and were deemed unrelated to CoQ(10). The most common adverse events seen were GI symptoms. Mean (± SD) CoQ10 blood levels achieved over the course of the trial were as follows: 1.26 ± 1.27 µg/mL (baseline, n = 28), 5.59 ± 2.24 µg/mL (1,200 mg/day, week 4, n = 26), 6.38 ± 3.25 µg/mL (2,400 mg/day, week 8, n = 25), 7.49 ± 4.09 µg/mL (3,600 mg/day, week 12, n = 23), and 6.78 ± 3.36 µg/mL (3,600 mg/day, week 20, n = 20). CoQ(10) was well tolerated with over 80% of subjects achieving the target dosage. Dosages of 2,400 mg/day may provide the best balance between tolerability and blood level achieved. Further studies examining the efficacy of 2,400 mg/day are planned.
