Hypervirulent Klebsiella pneumoniae (hvKp) infections are being increasingly reported globally, and cause severe central nervous system (CNS) and multiorgan infections even in immunocompetent individuals. The recent emergence of hvKp antibiotic resistance has generated escalating concern about effective infection control for this potentially neuroinvasive pathogen. Herein, we report two cases of Klebsiella pneumoniae-related CNS infection, including one patient with antimicrobial-resistant hvKp, confirmed by string test that demonstrated a hypermucoviscous phenotype.

OBJECTIVES: To find the main cause of facial nerve dysfunction in vestibular schwannoma (VS) surgery and review the prognosis of facial function in relation to tumor size, preoperative facial function and surgical approach. METHODS: We reviewed the surgical outcome of 134 patients with VS treated in our department between 1994 and 2008. All patients included in the study had postoperative facial paralysis after surgical management of their VS. There were 14 women and 7 men. The mean age was 48.5 years, with a mean follow-up period of 57 months. RESULTS: Twenty-one patients (sustained facial palsy, 4; newly developed facial palsy, 17) had facial nerve paralysis after surgery: ten patients in large VS and eleven patients in small VS. In large VS group, 4 patients had facial nerve function of HB grade II, 3 patients had HB grade III, and 3 patients had HB grade IV. In small VS group, 9 patients had HB grade II and 2 patients had HB grade IV. Middle cranial fossa approach rather than translabyrinthine approach for the preservation of hearing, led to facial nerve deterioration and the patients who had facial nerve paralysis perioperatively, had resulted in permanent facial paralysis. CONCLUSION: The tumor size in VS is certainly one of the most important prognostic factors. However, VS tumor size alone should not be considered a unique prognostic indicator. The surgical approach used, which may be related to tumor size, based on the surgeon's experience, can be a deciding factor, and the status of the facial nerve injured by the tumor can influence postoperative facial nerve function.

PURPOSE: The purpose of this study is to investigate peculiar patterns of facial asymmetry following incomplete recovery from facial paralysis that require optimal physical therapy for effective facial rehabilitation, and to decrease the incidence of avoidable facial sequelae. MATERIALS AND METHODS: This study involved 41 patients who had facial sequelae following the treatment of various facial nerve diseases from March 2000 to March 2007. All patients with a follow-up of at least 1 year after the onset of facial paralysis or hyperactive function of the facial nerve were evaluated with the global and regional House-Brackmann (HB) grading systems. The mean global HB scores and regional HB scores with standard deviations were calculated. Other factors were also analyzed. RESULTS: Four patterns of facial asymmetry can be observed in patients with incomplete facial recovery. The most frequently deteriorated facial movement is frontal wrinkling, followed by an open mouth, smile, or lip pucker in patients with sequelae following facial nerve injury. The most common type of synkinesis was unintended eye closure with an effort to smile. CONCLUSION: We described common configurations of facial asymmetry seen in incomplete recovery following facial nerve injury in an attempt to develop an optimal strategy for physical therapy for complete and effective facial recovery, and to decrease the incidence of avoidable sequelae.

In the management of advanced maxillary sinus cancer, sometimes it requires an extensive ablation and orbital exenteration that results in large and full defects of the cheek and orbital regions. Reconstruction of large orbital-maxillary defects can be accomplished in one stage by microsurgical free transfer of rectus abdominis myocutaneous flap. The muscle component is suitable to fill the orbital and maxillary cavities, and the skin components are used for cheek, palate and lateral nasal cavity wall reconstruction as a three-dimentional folded free flap. Major problems with this flap are the bulkiness, the possibility of abdominal hernia and muscle weakness following the removal of the rectus abdominis muscle. Free deep inferior epigastric artery skin flap without rectus abdominis muscle is available in the reconstruction of large orbital-maxillary defect without the problems of the rectus abdominis myocutaneous free flap. We experienced one case of rectus abdominis myocutaneous free flap, and one other case of inferior rectus abdominis free flap for the reconstruction of huge surgical defects due to radical maxillectomy with orbital excenteration. Both of the patients were satisfied and there have been no severe complication associated with these technique.

Mucocele is a benign, encapsulated lesion, lined by epithelium and filled with mucus. Found mostly in the frontal and ethmoid sinus, sinonasal mucoceles cause several symptoms depending on the location. We report a case of mucocele found in the petrous apex that caused ear fullness. It was completely treated with endoscopic sphenoid marsupialization.

Hypernatremia, defined as a rise in the serum sodium concentration to a value exceeding 145 mM/L, is a common electrolyte disorder. Diabetes insipidus is a common cause of hypernatremia, caused by impaired production or reduced responses to vasopressin. The resultant morbidity may be inconsequential, serious, or even life-threatening. However, hypernatremia rarely occurs during anesthesia and surgery. A 45-year-old female patient with craniopharyngioma was scheduled for tumor resection. Hypernatremia (serum sodium, 170 mM/L) occurred suddenly at the end of the surgery. To treat hypernatremia, 0.45% normal saline was used. Although serum sodium concentration was reduced faster than expected, the patient did not have any complications.

Medial femoral cutaneous nerve(MFCN), a sensory branch of the femoral nerve, supplies the skin over the anteromedial aspect of the thigh and knee. Posterior femoral cutaneous nerve(PFCN), comprised of fibers originating from the anterior and posterior divisions of the first three sacral segments, supplies the skin over the posterior aspect of the thigh. Forty nerves of twenty healthy adults, ages from 20 to 58, were tested. The onset and peak latencies of MFCN were 2.3+/-0.2 ms and 2.9+/-0.2 ms respectively. The baseline to peak amplitude was 6.5+/-2.3 V. The onset and peak latencies of PFCN were 2.4+/-0.2 ms and 2.9+/-0.2 ms respectively. The baseline to peak amplitude was 7.1+/-1.7 V.
