Reinforced endotracheal tubes (ETTs) are designed to resist kinking or compression. However, these have a potential risk of being obstructed or severed by a patient's bite. We report a case in which a reinforced ETT was severed by tube-bite while the patient was in the prone position during an intensive care unit stay. Bronchoscopic evaluation showed that the severed distal part of the tube had lodged in the patient's right main bronchus, and it had to be surgically removed. The patency of reinforced ETTs should be carefully monitored in patients intubated in the prone position.

BACKGROUND: Various surgical techniques have been developed to address senile upper eyelids. Upper blepharoplasty has limited efficacy in natural periorbital rejuvenation for severe lateral hooding of the upper eyelids, as well as often producing a 'surprised look'. Subbrow excision is a popular method in East Asia for the correction of eyelid drooping, especially on the lateral side as periorbital rejuvenation. However, medial upper eyelid skin redundancy often tends to be undercorrected. Here, we present a few cases of revisional blepharoplasty, especially for medial crease formation, to improve aesthetic results. METHODS: Five patients, for a total of 10 eyelids, who underwent revisional blepharoplasty from January 2011 to January 2015 after a previous subbrow excision, were included. Patients were dissatisfied with uncorrected excessive skin on the medial part of the upper eyelid after a previous subbrow excision; thus, they underwent revisional blepharoplasty for medial crease formation. RESULTS: During the follow-up period, patients were aesthetically satisfied with the postoperative results. No patients suffered from any complications during the follow-up period. CONCLUSIONS: After a previous unfavorable subbrow excision, medial crease formation, via a very minimally invasive technique, could be a favorable option to improve patient satisfaction without postoperative complication or discomfort.

Temporal hollowing is a common complication that occurs after coronal approach surgeries. However, temporal hollowing without previous nerve damage or trauma history is rare. Herein, we present a patient with cryptogenic temporal hollowing. A 22-year-old man without any history of craniofacial interventions or trauma presented with temporal hallowing. Magnetic resonance imaging revealed fatty degeneration of the left temporalis muscle. Electromyography and nerve conduction study showed no signs of neurologic abnormalities. The patient received autologous fat injection of 30 mL harvested from the left thigh using the modified Coleman technique. Temporal hollowing is commonly caused by atrophy of the superficial temporal fat pad. Its incidence is reported to be as high as 6% after coronal approach operation. Augmentation using porous hydroxyapatite or titanium mesh is a treatment option. Autologous fat graft can also be an option for mild to moderate temporal hollowing. In this case, a patient with no history of trauma, surgery, or myogenic disease developed temporal hollowing. Further study of the littleknown cryptogenic form of temporal hollowing is warranted.

BACKGROUND: Polyomavirus BK (BKV) infection is an important cause of graft loss in kidney transplant patients.PURPOSE: The purpose of this study was to evaluate clinical findings and risk factors for BKV in pediatric patients after kidney transplantation.METHODS: This retrospective single-center study included 31 pediatric kidney transplant recipients from January 2002 to December 2017. Two patients received 2 transplantations during the study period, and each transplant was analyzed independently. Total number of cases is 33 cases with 31 patients. BKV infection was confirmed from blood samples via periodic quantitative polymerase chain reaction.RESULTS: The mean age at kidney transplantation was 11.0±4.7 years, and the male-to-female ratio was 2.7:1. Three patients had a past medical history of high-dose chemotherapy and autologous stem-cell transplantation for solid tumors. Nine patients (27.3%) developed BKV infection. The median period from kidney transplantation to BKV detection in blood was 5.6 months. There was no statistically significant difference in estimated glomerular filtration rate between patients with and those without BKV infection. Among 9 patients with BKV viremia, 7 were treated by reducing their immunosuppressant dose, and BKV was cleared in 6 of these 7 patients. In the other 2 BKV-positive patients, viremia improved without immunosuppressant reduction.CONCLUSION: BKV infection is common in children with kidney transplantation and might not have affected short-term renal function in our patient sample due to early immunosuppressant reduction at the time of BKV detection.
