Background:
The tracheal bronchus in Kartagener syndrome is a rare case that may cause difficulty in one-lung ventilation (OLV). Here we reported a case of successful OLV using bronchial blocker in a patient with tracheal bronchus and Kartagener syndrome (KS).Case: A 66-year-old female patient with Kartagener syndrome was admitted for left-side diaphragmatic plication. The patient’s preoperative computed tomography image showed a tracheal bronchus of the apical segment in the right upper lobe. The patient received epidural analgesia and general anesthesia through total intravenous anesthesia. An EZ-Blocker® (Teleflex Life Sciences Ltd., Ireland) was used to perform OLV.
Conclusions
OLV through an EZ-Blocker® can be successfully performed in tracheal bronchus patients with Kartagener syndrome without side effects.

Objective:
This study aimed to investigate the impact of baseline values and temporal changes in body composition parameters, including skeletal muscle index (SMI) and visceral adipose tissue area (VAT), measured using serial computed tomography (CT) imaging on the prognosis of operable breast cancers in Asian patients.
Materials and Methods:
This study retrospectively included 627 Asian female (mean age ± standard deviation [SD], 53.6 ± 8.3 years) who underwent surgery for stage I–III breast cancer between January 2011 and September 2012. Body composition parameters, including SMI and VAT, were semi-automatically calculated on baseline abdominal CT at the time of diagnosis and follow-up CT for post-treatment surveillance. Serial changes in SMI and VAT were calculated as the delta values. Multivariable Cox regression analysis was used to evaluate the association of baseline and delta SMI and VAT values with disease-free survival.
Results:
Among 627 patients, 56 patients (9.2%) had breast cancer recurrence after a median of 40.5 months. The mean value ± SD of the baseline SMI and baseline VAT were 43.7 ± 5.8 cm2 /m2 and 72.0 ± 46.0 cm2 , respectively. The mean value of the delta SMI was -0.9 cm2 /m2 and the delta VAT was 0.5 cm2 . The baseline SMI and VAT were not significantly associated with disease-free survival (adjusted hazard ratio [HR], 0.983; 95% confidence interval [CI], 0.937–1.031; p = 0.475 and adjusted HR, 1.001; 95% CI, 0.995–1.006; p = 0.751, respectively). The delta SMI and VAT were also not significantly associated with disease-free survival (adjusted HR, 0.894; 95% CI, 0.766–1.043; p = 0.155 and adjusted HR, 1.001; 95% CI, 0.989–1.014; p = 0.848, respectively).
Conclusion
Our study revealed that baseline and early temporal changes in SMI and VAT were not independent prognostic factors regarding disease-free survival in Asian patients undergoing surgery for breast cancer.

Background:
The thoracic paravertebral block is an effective analgesic technique for postoperative pain management after breast surgery. The ultrasound-guided retrolaminar block (RLB) is a safer alternative to conventional paravertebral block.Thus, we assessed the analgesic efficacy of ultrasound-guided RLB for postoperative pain management after breast surgery.
Methods:
Patients requiring breast surgery were randomly allocated to group C (retrolaminar injection with saline) and group R (RLB with local anesthetic mixture).The RLB was performed at the level of T3 with local anesthetic mixture (0.75% ropivacaine 20 mL + 2% lidocaine 10 mL) under general anesthesia before the skin incision. The primary outcome was cumulative morphine consumption using intravenous patient-controlled analgesia (IV-PCA) at 24 hour postoperatively. The secondary outcomes were the visual analogue scale (VAS) scores at 1, 6, 24, and 48 hour postoperatively and the occurrence of adverse events and patient satisfaction after the surgery.
Results:
Forty-six patients were included, 24 in group C and 22 in group R. The cumulative morphine consumption using IV-PCA did not differ between the two groups (P = 0.631). The intraoperative use of remifentanil was higher in group C than in group R (P = 0.025). The resting and coughing VAS scores at 1 hour postoperatively were higher in group R than in group C (P = 0.011, P= 0.004). The incidence of adverse events and patient satisfaction was not significantly different between the two groups.
Conclusions
A single injection of ultrasound-guided RLB did not reduce postoperative analgesic requirements following breast surgery.

GNE, or bifunctional UDP-N-acetylglucosamine 2-epimerase/N-acetylmannosamine kinase, myopathy presents with symptoms of foot drop, followed by lower and upper extremity muscle weaknesses and sparing of the quadriceps. Myopathies usually increase the risks of complications related to general anesthesia. The anesthetic management of patients with GNEmyopathy has not been previously reported. Herein, we report a case of GNEmyopathy in a 37-year-old woman and discuss anesthetic considerations for elective laparoscopic hysterectomy and bilateral salpingectomy, focusing on the postoperative airway management. We avoided administering neuromuscular-blocking agents and instead used a laryngeal mask airway. The anesthetic management combining the use of a laryngeal mask airway and desflurane without neuromuscular-blocking agents provided sufficient abdominal and diaphragmatic muscle relaxations for sustaining the pneumoperitoneum for laparoscopic surgery.

Thromboelastography or rotational thromboelastometry, is being increasingly utilized in cardiac surgery of late. However, it is an indirect test and is not available in all centers. Low fibrinogen levels before and after cardiopulmonary bypass (CPB) have been described to be associated with postoperative bleeding in cardiac surgery. This study explored the usefulness of reduction ratio of the fibrinogen levels before CPB (preCPB) and after CPB (postCPB) in predicting postoperative hemorrhage. A retrospective, observational study of adult patients who underwent cardiac surgery with CPB between February 2014 and January 2016 was conducted, which included a total of 264 patients. The fibrinogen levels were measured twice, preCPB and postCPB, and the fibrinogen reduction ratio was acquired [(preCPB − postCPB)/preCPB]. Postoperative blood loss, which was defined as the blood collected from the chest drain for 12 hours following arrival at the intensive care unit, was considered severe if it was more than 1,000 mL. A multivariate analysis showed that fibrinogen reduction ratio, sex, and postCPB platelet count were significantly associated with severe postoperative bleeding. However, the pre- and postCPB fibrinogen levels were not significantly associated with severe bleeding. Furthermore, a fibrinogen reduction ratio of > 41.3% was independently associated with postoperative severe bleeding, with an odds ratio of 3.472 (1.483–8.162). These results suggest that the reduction ratio of pre- and postCPB fibrinogen levels may be utilized in predicting postoperative bleeding.

BACKGROUND: Patient-controlled epidural analgesia (PCEA) is known to provide good postoperative analgesia in many types of surgery including laparoscopic surgery. However, no study has compared PCEA with patient-controlled intravascular analgesia (PCIA) in laparoscopic radical prostatectomy (LARP). In this study, the efficacy and side effects of PCEA and PCIA after LARP were compared. METHODS: Forty patients undergoing LARP were randomly divided into two groups: 1) a PCEA group, treated with 0.2% ropivacaine 3 ml and 0.1 mg morphine in the bolus; and 2) a PCIA group, treated with oxycodone 1 mg and nefopam 1 mg in the bolus. After the operation, a blinded observer assessed estimated blood loss (EBL), added a dose of rocuronium, performed transfusion, and added analgesics. The numeric rating scale (NRS), infused PCA dose, and side effects were assessed at 1, 6, 24, and 48 h. RESULTS: EBL, added rocuronium, and added analgesics in the PCEA group were less than those in the PCIA group. There were no significant differences in side-effects after the operation between the two groups. Patients were more satisfied with PCEA than with PCIA. The NRS and accumulated PCA count were lower in PCEA group. CONCLUSIONS: Combined thoracic epidural anesthesia could induce less blood loss during operations. PCEA showed better postoperative analgesia and greater patient satisfaction than PCIA. Thus, PCEA may be a more useful analgesic method than PICA after LARP.

Despite its widespread use, complication of incentive spirometry has been rarely reported. We report a case of pharyngeal reperforation following incentive spirometry. A 75-year-old female, had a history of long-term steroid use, entered the intensive care unit for maintenance of mechanical ventilation following surgical repair of a pharyngeal perforation. After ventilator weaning, incentive spirometry was implemented on postoperative day 4. Immediately after incentive spirometry use, patient's neck began to swell, and subcutaneous emphysema was palpated. Pharyngeal reperforation was suspected on neck computed tomography, and emergency surgery was performed. Surgery revealed a 3-cm long rupture from the hypopharynx to the esophagus. The causes were thought to be delayed wound healing due to long-term steroid use and a sudden increase in pharyngeal pressure due to incentive spirometry. In conclusion, particular attention should be paid when using incentive spirometry after head and neck surgery in patients with a history of long-term steroid use.

PURPOSE: Interleukin (IL)-9 induces allergic responses; however, the roles of anti-IL-9 antibody in the induction of tolerance remain unclear. This study investigated the effects of anti-IL-9 antibody on oral tolerance (OT) in a mouse model of allergic rhinitis (AR). METHODS: BALB/c mice were divided into 4 groups: the control, AR, OT, and OT with anti-IL-9 antibody (OT+IL9AB) groups. Ovalbumin (OVA) was used for sensitization and challenge. Mice in the OT and OT+IL9AB groups were fed OVA for immunotherapy. During immunotherapy, OT+IL9AB mice were injected with anti-IL-9 antibody. Allergic symptoms, tissue eosinophil counts, and serum OVA-specific immunoglobulin E (IgE) were measured. The mRNA expressions of cytokines and transcription factors of T cells of nasal mucosa were determined by real-time polymerase chain reaction (PCR). The protein levels of GATA3, ROR-γt, and Foxp3 in nasal mucosa were determined by Western blot. CD4⁺CD25⁺Foxp3⁺ T cells in the spleen were analyzed by flow cytometry. RESULTS: Administration of anti-IL-9 antibody decreased allergic symptoms, OVA-specific IgE levels, and eosinophil counts. In addition, it inhibited T-helper (Th) 2 responses, but had no effect on Th1 responses. Protein levels of ROR-γt and mRNA levels of PU.1 and ROR-γt were reduced by anti-IL-9 antibody. Anti-IL-9 antibody increased Foxp3 and IL-10 mRNA expression, Foxp3 protein, and induction of CD4⁺CD25⁺Foxp3⁺ T cells. CONCLUSIONS: Anti-IL-9 antibody decreased allergic inflammation through suppression of Th2 and Th17 cells. Anti-IL-9 antibody enhanced the tolerogenic effects of regulatory T cells. These results suggest that anti-IL-9 antibody might represent a potential therapeutic agent for allergen immunotherapy in patients with uncontrolled allergic airway disease.

We report a case that a 68-year-old man taking hydroxyurea for essential thrombocythemia produced milky urine during propofol infusion. Under microscopic analysis, the cloudy urine sample was revealed to comprise uric acid crystals. Postoperatively, kidney function such as urine output and blood urea nitrogen to creatinine ratio showed no abnormality. We suggest that the cloudy urine may be due to the increased excretion of uric acid after administration of propofol. Although this rare case of cloudy milky urine is resolved on its own, we need to consider the possibility of such urine color changes. It is particularly important to understand that medication, preoperative serum uric acid level, urine pH, and the hypothermal operating room can change the color of urine through the presence of uric acid crystals.

Anesthetic experience in frontotemporal dementia (FTD) with severe hypotension associated autonomic dysfunction has not yet been reported. Here in case, we report on the case of treatment with vasopressin to refractory hypotension in FTD patient. A 54-year-old male presented with a ten-year history of FTD with frequent syncope. The patient was scheduled to undergo subtotal gastrectomy for resection of stomach cancer. During the operation, sudden hypotension occurred and it was refractory to fluid and 1 unit of blood resuscitation and did not respond to catecholamine. Transesophageal echocardiography showed normal heart with adequate volume state. After intravenous administration of arginine vasopressin, the patient's vital signs returned to baseline values. Arginine vasopressin might be considered as a valuable alternative for treatment of severe refractory hypotension in autonomic dysfunction patients with FTD.
