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.

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.

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.

BACKGROUND: There are several ways to treat for recurrent pericardial effussion and cardiac tamponade due to malignancy. They are repeated pericardiocentesis, pericardial instillation of sclerosing and chemotherapeutic agents, surgical creation of a pericardial window and transthoracic pericardiectomy. Surgical techniques are usually effective but bear a significant morbidity and mortality especially in chronic debilitating cancer patients. So percutaneous balloon pericardial window as an alternative to surgery in these patients. METHODS: After pericardiocentesis was performed, a 0.035 inch J-tip guidewire was advanced into the pericardial space. And a pigtail catheter was advanced over the wire. A moderate amount of pericardial fluid were removed. A nd then the pigtail catheter was withdrawn and 8F sheath was inserted. A20mm diameter, 4cm long(Single balloon method) or two 10mm diameter, 4cm long balloon dilating catheter(Double balloon medium) was advanced over the wire to straddle the parietal pericardial border though the sheath. Several inflations of the balloon with a solution containing 50% radiographic contrast medium were performed until disappearance of the balloon waist. After balloon dilation, contrast medium from the pericardial space to subcutaneous tisse suggesting successful PBPWF. Single ballon method was employed in 4 patients and Dould balloon method in 2 patients. RESULT: We performed percutaneous balloon pericardial window formation in 6 patiemts with malignant pericardial effusion. We did percutaneous balloon pericardial window formation successfully in 5 patients and failed due to adhesion of parietal pericardium in 1 patient. One patient developed recurrent pericardial effusion with tamponade at a mean follow-up of 11.49.6 months(1.5-26 months). Conclusion: These results suggest that PBPWF is an alternative method less invasive than subxiphoid surgical windowing, espesially in critically ill patients with recurrent malignant pericardial effussion. It carries less risks and has more constant effect than repeated pericardiocentesis.

Since the introduction of epidural corticoateroid injections for the management of sciaticall, luintosacral radiculopathy has become one of the most common pain problems enco-untered by anesthesiologists. In order to function effectively, anesthesiologiats should be able to: 1) recognize those syndromes which may respond to nerve block: 2) understand the pathophysiology of the conditions being treated and 3) be familiar with alternate ther-apeutic pathways for patientg not responding to merre b1ock. There are many etiologic factors of low back pain and lumbosacral radiculopathy. Particularly, Nerve root compression caused by a protruding disc, a osteophyte or tumors are usually responsible for pain. Neural inflammation, therefore, is considered to play a major role in pain production.The use of local anesthetics in mixture with steroids is believed to break down neural inflammation. Steroids and local anesthetics were injected lumbar or caudal epidmal to 106 patients for the purpose of relieving low back pain and lumbosacral radiculopathy. The resu1ts are as follows : Excellent Pain relieved group : 27 Patients (25.5%) Good Pain relieved group: 49 Patients(46.1%) Fair pain relieved group : IS patients(14.2%) Not effective group : 15 Patients (14.2%).

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.Medical Treatment of Acute Decompensated Heart Failure Syndrome.
Korean Journal of Medicine 2015;88(2):121-126
Acute decompensated heart failure syndrome is the most common cause of cardiovascular hospitalization with a high rate of in-hospital mortality. The clinical presentation is characterized by different clinical profiles due to various underlying causes, precipitating factors, volume status, and tissue perfusion status. Therefore, clinicians should carefully examine the hemodynamic status of acute decompensated heart failure patients in the initial management. Risk stratification might provide guidance to clinicians who care for patients with acute decompensated heart failure syndromes, and might improve decision-making in emergent care when decisions must be made quickly and accurately. Intravenous loop diuretics are the main treatment option for the relief of congestive symptoms. This article reviews how to assess hemodynamic status of acute decompensated heart failure patients and how to perform risk stratification of patients. Additionally, the initial treatment approach with a variety of pharmacological therapies including inotropic agents, diuretics, beta-blockers, angiotensinogen converting enzyme-inhibitors, angiotensin receptor blockers, digoxin, and other medications that are routinely prescribed in the management of acute decompensated heart failure patients are also discussed.

10.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.
