We present a novel technique to approach far lateral lumbar pathologies using a bitubular, biportal endoscopic system and a paramedian approach. Background: Conventional approaches for lumbar far lateral discectomy range from open approaches to newer minimally invasive approaches such as tubular discectomy and single portal endoscopic discectomy. We present a case of a patient suffering with a left L3–4 and left L4–5 extraforaminal disc herniation who was treated successfully with a left sided bitubular, biportal endoscopic 2 level far lateral discectomy. A paramedian ‘bitubular’ biportal endoscopic approach is safe and effective for far lateral lumbar pathologies with excellent visualisation due to good outflow of irrigation fluid.

Mucopolysaccharidoses (MPSs) are a group of inherited heterogenous metabolic disorders, caused by deficiency of an enzyme involved in the degradation of mucopolysaccharides, and thus deposition of mucopolysaccharides in all connective tissue. MPS type III is heparan sulphate storage disorder, especially marked central nervous system involvement. As with all the MPS disorders, this patient with MPS III presents coarse outlook features, such as macrocephaly, macroglossia, prominent mandible, short neck, and unstable atlantoaxial joints, as well as tracheal abnormality. These clinical findings give significant challenges to the anesthesiologist for adequate airway management and tracheal intubation. Recently, a number of new devices have been developed to facilitate intubation. We report an experience of facilitated tracheal intubation using video styletscope (OptiScope PM201(R), Pacific Medical, Seoul, Korea) in a 16 year old male patient with MPS III, who was undergoing inguinal hernia repair.

BACKGROUND: The hemodynamic reactions to psychological stress were different between adult genders. Our aim was to investigate the hypothesis that preoperative cardiovascular responses in children undergoing ear reconstruction surgeries will be different according to gender. METHODS: We obtained data from children, aged 7-16 years, undergoing reconstruction surgeries for microtia during 2005-2009. Number of boys receiving primarily rib cartilage graft (RCG) surgery and secondarily ear elevation procedure was 121 and 83, respectively, and girls 48 and 28, respectively. Preoperative systolic (S), diastolic blood pressure (DBP) and heart rate (HR) on each surgery were compared between genders, and within genders. RESULTS: Boys were younger than girls by one year at first and second admission. Boys showed significantly lower preoperative DBP than girls (mean difference [MD]: -3.7 mmHg, 95%CI: -6.1 to -1.3, P = 0.032) before RCG, whereas significantly higher SBP (MD: 21.5 mmHg, 95%CI: 16.6 to 26.4, P < 0.001), and DBP (MD: 10.2 mmHg, 95%CI: 6.0 to 14.4, P < 0.001) before ear elevation. Comparison between the two surgeries within the same gender indicated that boys demonstrated significantly higher SBP (P < 0.001) and DBP (P < 0.001) before ear elevation than before RCG; however SBP was comparable and DBP was significantly lower (P = 0.035) before ear elevation than before RCG in girls. CONCLUSIONS: Gender impact on the preoperative cardiovascular reactions was evident in children undergoing microtia surgery.

Essential thrombocythemia (ET) is characterized by most cases in which platelet counts exceed 1 million/µL. ET is usually no symptoms during non-pregnancy, but arterial and venous thrombosis and hemorrhage may develop in pregnancy. Pregnancy in these patients is associated with many complications in both pregnant women and fetuses such as recurrent abortion, intrauterine fetal growth restriction, preterm delivery, preeclampsia, and stillbirth. In these patients, aspirin, low-molecular-weight heparin (LMWH), and interferon alpha (INF-α) are recommended during pregnancy. We report a case of four consecutive abortions despite being treated with INF-α, low dose aspirin, and LMWH in patient with ET.

BACKGROUND: Doppler myocardial performance index (DMPI), defined as the sum of isovolumetric contraction time (IVCT) and isovolumetric relaxation time (IVRT) divided by ejection time (ET), is an easily measurable index which has been shown to reflect the severity of the disease. It has been known each component of DMPI, as IVCT, IVRT and ET, was affected by the change of preload. Therefore, the objective of this study was to estimate the changes of DMPI during intravascular volume reduction in patients with end-stage renal disease and to determine which components of DMPI contribute to DMPI alteration during intravacular volume reduction. METHODS: We measured blood pressure, heart rate, M-mode echocardiographic and Doppler parameters within 10 minutes before and after hemodialysis and ultrafitration with amount of average 2 L. RESULTS: We studied 40 end-stage renal disease patients (22 men and 18 women, mean age of 52 years) who had left ventricular hypertrophy 39 (97.5%) and normal left ventricular systolic function (diastolic interventricular septal thickness, 13.8+/-2 mm; diastolic left ventricular posterior wall thickness, 12.6+/-2 mm; Ejection fraction, 63.1+/-0.1%). Peak E-wave velocity was significantly decreased after hemodialysis and ultrafiltration (84.85+/-25 cm/s vs 72.89+/-23 cm/s, p<0.05), but other Doppler parameters such as peak A-wave velocity and E deceleration time were not changed. E/A ratio showed decreased tendency which was not significant statistically (p<0.097). DMPI was significantly increased after hemodialysis and ultrafiltration (0.41+/-0.14 vs 0.45+/-0.15, p<0.001). The increase of DMPI was mainly affected by prolongation of IVRT/ET which was due to prolonged IVRT, but IVCT/ET was not changed. The changes of DMPI was little with hemodialysis and ultrafiltration of about 2 L. CONCLUSION: We could prove that DMPI was preload dependent parameter of myocardial function. We suggest the change of preload should be considered as an important factor which may alter the DMPI.

Purpose:
Preoperative tumor size is associated with clinical stage, treatment plan and even survival rate of patient. We investigated the accuracy of tumor size estimation between magnetic resonance imaging (MRI) and ultrasonography (US) findings, comparing these with pathologic tumor size in the diagnosis of early breast carcinoma.
Methods:
Between 2011 and 2016, 136 patients with early breast cancer were analyzed and their tumor size on US and MRI findings were compared with their pathologic tumor size retrospectively. The background parenchymal enhancement of MRI was categorized as minimal, mild, moderate, and extreme. The patients who underwent neoadjuvant chemotherapy, had positive resection margins, underwent excisional biopsy for cancer diagnosis, and had non-mass lesions on MRI scans, were excluded.
Results:
In all, 83.1% of the cases showed concordance between MRI findings and pathologic tumor size within 0.5cm. MRI overestimated the findings by 10.3% and underestimated them by 6.6%; 78.7% showed concordance between US findings and pathologic tumor size within 0.5cm. US overestimated the findings by 5.9% and underestimated them by 15.4%. The tumor size on MRI (r=0.87) showed a stronger correlation to the pathologic tumor size than that on US (r=0.64) in early breast cancer patients. US had a tendency to underestimate the tumor size. The degree of breast parenchyma did not affect the accuracy of the measurement of preoperative tumor size.
Conclusion
MRI is relatively more accurate than US for assessing preoperative tumor size in breast cancer patients. US tends to underestimate tumor size.
