Purpose: This study aimed to evaluate the usefulness of the needle aspiration alternative to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage. Methods: From January 1998 to June 2008, we retrospectively reviewed 38 children treated with needle aspiration as management with suppurative cervical lymphadenitis instead of open surgical drainage. Results: All 38 children underwent only 1 puncture. Two patients (5.2%) out of 38 patients experienced reformation of an abscess and all recovered completely after re-treatment with antibiotics. Minor complications were detected in 2 patients (5.2%). One complication originated from remnant necrotic tissue and the other involved formation of a small scar in two patients, which resolved spontaneously. There were no major complications. Conclusion: Needle aspiration can be a simple, safe, and effective alternative procedure to open surgical drainage of children with suppurative cervical lymphadenitis requiring surgical drainage.

The main goal of this study was to develop a convenient strengthening technique for retrofitting of reinforced concrete members. For this purpose a new retrofitting material so-called prefabricated-HSPRCC (high performance steel plate reinforced cementitious composite) panel was developed by using high performance concrete and perforated steel plate. Prefabricated-HSPRCC composes advantages of steel and high performance concrete. The prefabricated-HSPRCC panels were either only bonded on the specimens using epoxy mortar or anchored to the specimen by steel bolts as well as bonding. Effect of different variations such as prefabricated-HSPRCC panel thicknesses, steel plate thicknesses, puncture orientation of perforated steel plate, existence of anchorage etc. were studied through a simple experimental work. The behaviour of the specimens under vertical point load was also studied by using simple mechanics. The retrofitted specimens were found to exhibit much better performance both in terms of strength and deformation capability. The anchorage application was found to positively affect this improved performance. Furthermore, as a result of the tests the best parameters of prefabricated-HSPRCC plate for improving strength and deformation capacities were determined.

We report a case of epidural hematoma occuring after bloody tap during epi-dural catheter for cancer pain control in thrombocytopenic patient. Two hours after epidurl puncture, patient experienced severe back pain and numbness of both legs. Following day, patient complained of motor paralysis and urinary difficulty. Diagnosis utilizing magnetic reasonance imaging, showed epidural hematoma extending from $T_{11}$ to $T_{12}$. Thrombocytopenia prevented surgical intervention. Therefore we restored conservative therapy with packed red cell, platelet concentration, steroid and hemostatic, which provided complete neurologic recovery, spontaneously over several days without surgical intervention.

This study was performed to investigate the effects of different fat diets on the serum lipid composition and on the morphology of liver tissue of the spontaneously hypertensive rats(SHR), Rats were fed for 17 weeks one of four fat diets, control(corn oil : beef tallow=1:1), beef tallow, grapeseed oil and soybean oil. Blood was withdrawn by heart puncture from each SHR, and used to determine the serum levels of total cholesterol, HDL-cholesterol, trigly ceride and phospholipid. No significant difference in body weight was observed in all diet groups. the total serum cholesterol was significantly lower in SHR fed grapeseed oil than that of other groups. The cholesterol lowering effect of grapeseed oil seemed to results from its high contents of phytosterol and linoleic acid. Also, serum HDL-cholesterol, triglyceride and phospholipid contents were low in all the groups. photochemical microscopic observations of the liver tissue revealed the congestion of sinosoid which is regarded as the characteristics of SHR, but no significant difference was observed among the groups.

This study was conducted to investigate the effect of repeated blood collection on the amount of vitamin E in serum and liver of the rats fed standard diet. Rats (Sprague Dawley strain) were fed standard were fed standard diet for several weeks. Blood was collected with on improved cardiac puncture method at regular intervals . The amount of vitamin E analogs were measured by the HPLC. 1) The growth curve of all groups was normal, but bodyweight gains of group II were significantly decreased in case of 7 week- rats whose blood was collected at intervals of two weeks. 2) The amount of vitamin E analogs in serum of rats during growth increased, but continuos blood collection could not affect on the amount of vitamin E in serum. Especially, in the group I serum vitamin E equivalent were significantly higher in case of 7 weeks than first week. 3) The amount of liver vitamin E analogs were changed irregularly, and especially, $\alpha$-Tocopherol equivalent were significantly higher in group II then other groups.

Cervical epidural steroid injection is frequently used in the conservative management of neck pain and cervical radiculopathy. Epidural cervical transforaminal injections are usually well-tolerated with mild side effects such as transient decreased sensory and motor function, or headache due to dural puncture. Although there are a few case reports about adverse effects of cervical epidural injection in the literature, it can cause severe complications such as large hematoma, infarction by spinal vascular injury. Subdural hematoma has been occurred much less common rather than epidural hematoma in the spinal cord. We report a rare catastrophic case of cervical spinal subdural hematoma with quadriparesis after cervical transforaminal epidural block.

Spontaneous intracranial hypotension (SIH) is considered to be a very rare disorder. It is characterized by an orthostatic headache that is aggravated with the patient in the upright position and it is relieved by the patient assuming the supine position. SIH is caused by a spontaneous spinal cerebrospinal fluid leakage without the patient having undergone trauma, surgery or dural puncture or having any other significant medical history. An autologous epidural blood patch (EBP) is effective in relieving SIH. We report here on a case of SIH with cerebrospinal fluid leakage at the upper cervical vertebral level and the middle thoracic vertebral level. The points of leakage were identified by radionuclide cisternography, and this patient was successfully managed by injecting an EBP at each level of leakage.

Postherpetic neuralgia is the most frequent complication of herpes zoster. Treatment of this neuropathic pain syndrome is difficult and often disappointing. Although postherpetic neuralgia is generally a self-limited condition, it can last indefinitely. Continuous epidural blockade for patients with acute zoster can shorten the duration of treatment. However, continuous epidural block has some complications such as infection, dural puncture, and total spinal and nerve damages. We report a case of myoclonus during continuous epidural block with ropivacaine, morphine, and ketamine in an acute zoster patient.

The effects of decursinol on various models of sepsis were investigated. Intra-peritoneal pretreatment of mice with various doses of decursinol ($1{\sim}100$ mg/kg) effectively suppressed lethality induced in three mouse models of experimental sepsis, i.e., lipopolysaccharide (LPS)/D-galactosamine (GalN), high-dose LPS (20 mg/kg), and cecal ligation and puncture (CLP). Intra-peritoneal pretreatment of mice with decursinol (50 mg/kg) markedly enhanced the LPS/GalN -induced increase of plasma interleukin-10 (IL-10) levels, without affecting plasma TNF-${\alpha}$, IL-6 and IL-12 levels. These results suggest that decursinol could be effective for prevention or treatment of sepsis.

Sepsis remains the leading cause of morbidity and mortality following trauma. Although hepatocellular dysfunction occurs during trauma and sepsis. the mechanism responsible for this remains unclear. We investigated the role of Kupffer cells in the alterations in microsomal drug metabolizing function during trauma and sepsis. Rats were subjected to trauma by femur fracture (FFx). After 72h, polymicrobial sepsis was induced by cecal ligation and puncture(CLP). (omitted)
