Successful treatment of arrhythmia with ß-blocker and flecainide combination in pregnant patients with Andersen-Tawil syndrome: A case report and literature review.

Andersen-Tawil syndrome (ATS) is a rare disorder characterized by a triad of ventricular arrhythmia (VA), dysmorphic features, and periodic paralysis. Due to the rarity of this condition, less is known about physiologic effect of pregnancy to ATS and arrhythmia. There is no established guideline for peripartum or postpartum treatment and prevention of arrhythmia in ATS; thus, the clinical management is challenging. We reported two KCNJ2-associated ATS patients who got pregnant and underwent vaginal birth safely. Both individuals had VA, micrognathia without periodic paralysis. ß-blocker plus flecainide could be an effective treatment combination when monotherapy failed to control arrhythmia. VA of two pregnant patients with ATS could be controlled by either physiologic changes associated pregnancy or the combination treatment of ß-blocker and flecainide.

Combining a small urinary catheter with an endo mini-retractor: a novel technique for laparoscopic selective vascular control.

The Pringle maneuver using a urinary catheter has been described and proven to be one of the best methods for laparoscopic intracorporeal vascular control. Selective vascular control provides many advantages over total inflow occlusion by the Pringle maneuver. However, laparoscopic selective vascular control by urinary catheter has not been described. We, herein, describe laparoscopic selective vascular control using a combined small urinary catheter with an endo mini-retractor, which inserted in a new way, named 'The J-shaped Loop'. This method makes the instrument more compact so we can selectively control the vascular pedicle. When selective vascular occlusion is desired, the loop is tightened and the tension is held just by the catheter itself. This novel technique is simple, safe, effective and reproducible, and, therefore, can be used as a good alternative to other intracorporeal techniques for laparoscopic liver resection.

Incidence of postoperative, major, adverse cardiac events in patients undergoing carotid endarterectomy: A single-center, retrospective study.

OBJECTIVE: This study aimed to determine the incidence of postoperative major adverse cardiac events for patients undergoing carotid endarterectomy. METHODS: This single-center, retrospective study recruited 171 carotid endarterectomy patients between January 1999 and June 2018. Patients who received a carotid endarterectomy in conjunction with other surgery were excluded. The primary outcomes were the incidences of major adverse cardiac events (comprising myocardial infarction, significant arrhythmias, congestive heart failure, and cardiac death) within 7 days, 7-30 days, and > 30 days-1 year, postoperatively. The secondary outcomes were the factors related to major adverse cardiac events and the incidence of postoperative stroke. The patients' charts were reviewed, and direct contact was made with them to obtain information on their status post discharge. RESULTS: The incidences of major adverse cardiac events within 7 days, 7-30 days, and >30 days-1 year of the carotid endarterectomy were 3.5% of patients (95% confidence interval: 0.008-0.063), 1.2% (95% confidence interval: 0.004-0.028), and 1.8% (95% confidence interval: 0.002-0.037), respectively. The major adverse cardiac events occurring within 7 days were arrhythmia (2.3% of patients), cardiac arrest (1.8%), myocardial infarction (1.2%), and congestive heart failure (1.2%), while the corresponding postoperative stroke rate was 4.7%. CONCLUSION: The 7-day incidence of major adverse cardiac events after the carotid endarterectomy was 3.5%. The most common major adverse cardiac event during that period was cardiac arrhythmia.

Immediate aortic dissection after transcatheter aortic valve replacement: A case report and review of the literature.

-Aortic dissection of descending aorta was detected by intraoperative TEE in a case of 67-year-old man with symptomatic severe aortic stenosis after TAVR. -Transesophageal echocardiogram after TAVR procedure is helpful to detect this rare complication.

Leukemic arthritis and severe hypercalcemia in a man with chronic myeloid leukemia: a case report and review of the literature.

BACKGROUND: Patients with chronic myeloid leukemia typically present with high white blood cell counts revealed during annual checkups. Leukemic arthritis and hypercalcemia are rare manifestations in patients with chronic myeloid leukemia. CASE PRESENTATION: A 35-year-old Thai man who had been diagnosed with chronic myeloid leukemia in the chronic phase developed blast crisis while he was receiving ongoing treatment with imatinib at 400 mg/day. Initially, he presented with oligoarthritis in both knees and ankles. A bone scintigraphy showed a prominent bony uptake, with a symmetrical, increased uptake in many bone areas. Induction therapy with a 7 + 3 induction regimen was prescribed in conjunction with 600 mg of imatinib once daily before switching to 140 mg of dasatinib. He subsequently developed severe hypercalcemia (total serum calcium of 17.8 mg/dL), with generalized osteolytic lesions detected on a bone survey. His serum vitamin D level was 50.64 ng/mL, while the serum parathyroid hormone level was 9.82 pg/mL. Despite the administration of an aggressive intravenously administered hydration, intravenously administered calcitonin, and 600 mg/day of imatinib, the severe hypercalcemia was refractory. We therefore decided to prescribe 20 mg/day of intravenously administered dexamethasone; fortunately, his serum calcium level decreased dramatically to normal range within a few days. CONCLUSIONS: Although leukemic arthritis and severe hypercalcemia are extraordinary presentations in patients with chronic myeloid leukemia, the advanced phase of the disease might bring on these symptoms. Apart from parathyroid hormone-related protein-related hypercalcemia, vitamin D is a mechanism of humoral-mediated hypercalcemia.
