1.Changes of hematological references depends on storage period and temperature conditions in rats and dogs.
Laboratory Animal Research 2016;32(4):241-248
Because changes in rat and dog hematological parameters according to storage conditions have been poorly documented, we sought to examine such changes. Blood analysis was performed using two hematology analyzers (ADVIA 2120i and Sysmex XN-V) after storage at room temperature and in cold storage for 5, 24, and 48 h, respectively. Interassay coefficients of variation for hematological parameters analyzed with the ADVIA 2120i and the XN-V showed similar. The levels of hematocrit, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and platelet (PLT) showed significant variations with time in blood samples of rats and dogs. The leukocyte subpopulation showed high variation with storage conditions. The data for leukocyte differential counts obtained using the ADVIA 2120i, XN-V, and a manual differential counting procedure showed good agreement for neutrophils and lymphocyte counts, but monocytes, eosinophils, and basophils showed differences between the procedures. In conclusions, most rat and dog hematological parameters showed minimal changes; however, some showed high variation with storage time and temperature, especially PLT and leukocyte subpopulations. In conclusion, when performing hematological analysis in dogs and rats, it will be exactitude to analyze blood samples in fresh condition and at least within 24 h in the cold storage.

Clinics in Orthopedic Surgery 2019;11(1):131-136
The approach we suggest was developed for cases in which the fourth and fifth lumbar and first sacral spinal nerves were affected in lumbar degenerative disc disease. Retrodiscal transforaminal epidural injection is known to be very effective for lumbar radiculopathy because of excellent access to primary pathology; however, access below L5 is often restricted by the anatomic characteristics of the L5–S1. In the translateral recess approach (TLR), proper final needle placement (i.e., in the axillary portion between the exiting and traversing nerve roots) can be achieved by setting the direction of the needle laterally and superiorly from the distal tip of the infra-adjacent spinous process toward the medial wall of the pedicle and neural foramen of the given level without neural injury. This approach is possible because of the wide interlaminar space in the L5–S1. Preganglionic epidural injection through TLR is an effective and safe spinal intervention for lumbosacral radiculopathy.

Candida vertebral osteomyelitis (CVO) is a rare disease that is a complication of intravenous drug use, but recently it has been recognized as mostly an opportunistic infection. Because CVO appears to mimic pyogenic spondylodiscitis in terms of the clinical and radiologic presentations, it is often neglected in a usual clinical setting. The clinical, radiological, and biological characteristics of CVO are often used to make a differential diagnosis with vertebral osteomyelitis from other etiologies. Once an initial proper diagnosis was performed, the treatment relies on the prompt initiation of appropriate pharmacotherapy and serial monitoring of the clinical progress. This paper report late-onset CVO in two young patients who underwent a heart transplant surgery and had postoperative systemic candidiasis. These two cases are a good reminder of the potential of CVO in immunosuppressive patients treated with anti-fungal agents. This paper presents these two cases with a review of the relevant literature.

STUDY DESIGN: Retrospective case series. OBJECTIVES: We retrospectively evaluated the clinical efficacy of postganglionic nerve block in symptomatic Schmorl nodules (SNs). SUMMARY OF LITERATURE REVIEW: SNs are common lesions that are often asymptomatic. In certain cases, SNs have been reported to cause severe axial back pain, thereby considerably impacting patients' quality of life. No consensus currently exists on the treatment of symptomatic SNs. MATERIALS AND METHODS: From October 2015 to October 2017, a total of 21 patients with symptomatic SNs diagnosed by magnetic resonance imaging (MRI) that did not respond to conservative treatment after 4 weeks were included in the study. All patients received postganglionic nerve block. We evaluated effective pain relief (improvement of back pain of more than 50% compared with before the intervention) and functional improvements, assessed by visual analogue scale (VAS) and Oswestry Disability Index scores obtained at 4 hours, 4 weeks, 8 weeks, 3 months, and 6 months after the procedure. RESULTS: Symptomatic SNs were more common at the L2-3 level, and the lower end plate was more commonly involved than the upper end plate. Eighteen of the 21 patients (85.7%) showed effective pain relief, and no deterioration was observed within the follow-up period. Throughout the follow-up period, the VAS remained significantly improved compared to before the procedure (p < 0.05). Complications were not reported in any cases. CONCLUSIONS: Postganglionic nerve block for symptomatic SNs that do not respond to conservative treatment is a non-invasive modality for pain relief.

BACKGROUND: Epinephrine used in surgery to provide hemostasis may elicit ventricular arrhythmias. A desirable anesthetic would not sensitize the myocardium to exogenously administered epinephrine. So the effect of sevoflurane, which was introduced to clinical anesthesia recently, on cardiac arrhythmias induced by the infusion of epinephrine was compared with those of halothane which was already known to epinephrine-induced arrhythmia in the 14 mongrel dogs. METHODS: The authors compared the arrhythmogenicity (three or more premature ventricular contractions, PVCs)of intravenously administered epinephrine in 14 mongrel dogs who were randomly assigned to receive sevoflurane (1.7 vol%) or halothane (0.75 vol%) anesthesia equipotently. The arrhythmogenic doses of epinephrine determined in this comparative study were expressed by both infusion rates of epinephrine during sevoflurane and halothane anesthesia. RESULTS: The mean values of the arrythmogenic infusion rates of epinephrine were 27.1 7.6 g/kg for sevoflurane and 2.7 0.8 g/kg for halothane. CONCLUSIONS: We concluded that the arrythmogenic doses of epinephrine during sevoflurane were significantly higher than those during halothane anesthesia.

8.The Effects of Epiblepharon Surgery on the Improvement of Astigmatism.
Journal of the Korean Ophthalmological Society 2014;55(3):343-347
PURPOSE: To evaluate the changes in visual acuity and astigmatism after epiblepharon surgery regarding preoperative age and astigmatism. METHODS: We retrospectively reviewed the charts of 37 patients with epiblepharon surgery. Preoperative best-corrected visual acuity and degree of astigmatism were obtained. Postoperative data were collected at 6 and 12 months. RESULTS: The mean patient age was 5.7 +/- 2.5 years. In the 5-9 year-old group and < or =3D group, significant improvement of mean BCVA was demonstrated (p = 0.02, p = 0.039, respectively). In the cylinder groups, 1-2 D, 2-3 D, and < or =3D showed decreased mean astigmatism (p = 0.006, p = 0.034, p = 0.015, respectively). CONCLUSIONS: Significant astigmatic reduction was found after surgical correction in epiblepharon patients with higher baseline astigmatism. These results suggest that an epiblepharon surgery should be considered in patients with a high levels of astigmatism.

9.A Case of Nasolacrimal Duct Obstruction after Two-Jaw Surgery.
Journal of the Korean Ophthalmological Society 2013;54(5):794-797
PURPOSE: To describe a case of nasolacrimal duct obstruction after two-jaw surgery. CASE SUMMARY: A 22-year-old woman presented with a 1-year history of epiphora after two-jaw surgery. Orbital CT showed 5 mm of focal soft tissue at the level of the distal nasolacrimal duct. Dacryocystography showed complete obstruction at the nasolacrimal duct level. Thus a nasolacrimal duct obstruction was diagnosed by physical and radiologic examination. CONCLUSIONS: In patients with epiphora who have undergone two-jaw surgery, precise examination and treatment is required in order to exclude nasolacrimal duct obstruction.

Compared with osteosarcoma of bone, primary osteosarcoma of the soft tissue is very rare. Extraskeletal osteosarcoma is also a highly malignant pleomorphic sarcoma composed of cells exhibiting primarily osteoblastic, and to a lesser extent, chondroblastic differentiation. A case of extraskeletal osteosarcoma in the right sole is presented in a 67 year old male. The patient had noticed a progressively enlarging soft tissue mass, during about 14 months. This sarcoma was located in the soft tissues without attachment to the skeleton, as determined by examination of the X-Ray findings. The mass of right plantar portion was simply excised and pathologically confirmed to be an extraskeletal osteosarcoma. The clinical and pathological features of this sarcoma are described, and brief review of the literature is made.
