Hereditary spherocytosis is the most common hereditary red blood cell membrane disorder. It results from a deficiency in certain proteins that are part of the red blood cell membrane cytoskeleton. We report a case of adrenal myelolipoma in a 23-yearold patient with hereditary spherocytosis. She was diagnosed with hereditary spherocytosis at 7 months of age. As she grew older, hemoglobin level was low, so splenectomy was recommended, but continuous follow up was not possible due to the circumstances of the patient, so the splenectomy was delayed. Adrenal myelolipoma was discovered incidentally at the age of 23 with abdominal pain and cholecystitis with gallstones at the time. Myelolipoma is a benign tumor of the mesenchymal origin;its etiology remains unclear. Myelolipoma is composed of adipose and hematopoietic tissues and mainly arises from adrenal tissues. The mass is often detected during routine radiologic examinations because myelolipoma is usually asymptomatic and not generally associated with hematologic diseases. The prevalence of myelolipoma appears to be increasing due to the increased use of imaging modalities. The association of myelolipoma with hereditary spherocytosis has rarely been reported in the literature. To our best knowledge, this is the first report of adrenal myelolipoma associated with hereditary spherocytosis in the Korean population.

BACKGROUND: Endotracheal intubation often causes sore throat and coughing. The aim of this study was to decrease the incidence and severity of cough, sore throat, and hemodynamic changes after extubation by endotracheal administration of 1% lidocaine. METHODS: Sixty patients physical status American Society of Anesthesiologists classes I, II, and III who received a surgery under general anesthesia were randomly divided into two groups. L group was given 1% lidocaine 0.5 mg/kg by endotracheal administration. The other group, N group, received the same volume of normal saline. The number of cough, the severity of sore throat with numerical rating score (NRS), incidence of local anesthetic systemic toxic reaction, laryngospasm, and hoarseness were recorded. In addition, the number of coughs was divided into three levels by its severity, and it was converted into an indicator of cough score. RESULTS: L group had a significantly lower number of cough and sore throat NRS (P value < 0.05) than the N group, and also hoarseness did not occur. The changes in the hemodynamic parameters, before and after the emergence of anesthesia, were more stable in the L group than those in the N group, but not statistically significant. CONCLUSIONS: The results of this study suggest that endotracheal administration of 1% lidocaine is effective and safe method to reduce cough and sore throat caused by extubation.

This study investigated the boundary of anserine bursa with the recommended injection site and shape on the insertion area of pes anserinus (PA), with the aim of improving clinical practice. Eighty six legs from 45 Korean cadavers were investigated. The mixed gelatin solution was injected to identify the shape of anserine bursa, and then the insertion site of the PA tendons was exposed completely and carefully dissected to identify the shape of the PA. The sartorius was inserted into the superficial layer and gracilis, and the semitendinosus was inserted into the deep layer on the medial surface of the tibia. The number of the semitendinosus tendons at the insertion site varied: 1 in 66% of specimens, 2 in 31%, and 3 in 3%. The gracilis and semitendinosus tendons were connected to the deep fascia of leg. Overall, the shape of the anserine bursa was irregularly circular. Most of the anserine bursa specimens reached the proximal line of the tibia, and some of the specimens reached above the proximal line of the tibia. In the medial view of the tibia, the anserine bursa was located posteriorly and superiorly from the tibia's midline, and it followed the lines of the sartorius muscle. The injection site for anserine bursa should be carried out at 20degrees from the vertical line medially and inferiorly, 15 or 20 mm deeply, and at the point of about 20 mm medial and 12 mm superior from inferomedial point of tibial tuberosity.

In order to understand the pathogenetic mechanism of adult respiratory distress syndrome (ARDS), the role of phospholipase A2 (PLA2) in association with oxidative stress was investigated in rats. Interleukin-1alpha (IL-1, 50 mug/rat) was used to induce acute lung injury by neutrophilic respiratory burst. Five hours after IL-1 insufflation into trachea, microvascular integrity was disrupted, and protein leakage into the alveolar lumen was followed. An infiltration of neutrophils was clearly observed after IL-1 treatment. It was the origin of the generation of oxygen radicals causing oxidative stress in the lung. IL-1 increased tumor necrosis factor (TNF) and cytokine-induced neutrophil chemoattractant (CINC) in the bronchoalveolar lavage fluid, but mepacrine, a PLA2 inhibitor, did not change the levels of these cytokines. Although IL-1 increased PLA2 activity time-dependently, mepacrine inhibited the activity almost completely. Activation of PLA2 elevated leukotriene C4 and B4 (LTC4 and LTB4), and 6-keto-prostaglandin F2alpha (6-keto-PGF2alpha) was consumed completely by respiratory burst induced by IL-1. Mepacrine did not alter these changes in the contents of lipid mediators. To estimate the functional changes of alveolar barrier during the oxidative stress, quantitative changes of pulmonary surfactant, activity of gamma glutamyltransferase (GGT), and ultrastructural changes were examined. IL-1 increased the level of phospholipid in the bronchoalveolar lavage (BAL) fluid, which seemed to be caused by abnormal, pathological release of lamellar bodies into the alveolar lumen. Mepacrine recovered the amount of surfactant up to control level. IL-1 decreased GGT activity, while mepacrine restored it. In ultrastructural study, when treated with IL-1, marked necroses of endothelial cells and type II pneumocytes were observed, while mepacrine inhibited these pathological changes. In histochemical electron microscopy, increased generation of oxidants was identified around neutrophils and in the cytoplasm of type II pneumocytes. Mepacrine reduced the generation of oxidants in the tissue produced by neutrophilic respiratory burst. In immunoelectron microscopic study, PLA2 was identified in the cytoplasm of the type II pneumocytes after IL-1 treatment, but mepacrine diminished PLA2 particles in the cytoplasm of the type II pneumocyte. Based on these experimental results, it is suggested that PLA2 plays a pivotal role in inducing acute lung injury mediated by IL-1 through the oxidative stress by neutrophils. By causing endothelial damage, functional changes of pulmonary surfactant and alveolar type I pneumocyte, oxidative stress disrupts microvascular integrity and alveolar barrier.

BACKGROUND AND OBJECTIVES: Arterial stiffness is a precursor to premature cardiovascular disease. The augmentation index (AI) and pulse pressure (PP) are cardiovascular risk factors. The aim of this study was to define the diagnostic values of the AI and PP from the peripheral arterial and central aortic waveforms in healthy subjects. SUBJECTS AND METHODS: We recruited 522 consecutive subjects (mean age 46.3+/-9.6 years, 290 males) who came to our facility for a comprehensive medical testing. We measured the body mass index (BMI), blood pressure, peripheral and central PP, and a pulse wave analysis that included the central and peripheral AI. RESULTS: The peripheral and central AIs in the female subjects were significantly higher than that in the male subjects (p<0.001). The peripheral and central PPs in the subjects with hyperlipidemia were significantly higher than subjects with normal lipid profiles (p<0.001). The peripheral and central PPs and peripheral and central AIs significantly increased with age. CONCLUSION: Pending validation in prospective outcome-based studies, a peripheral PP of 70 mmHg, central PP of 50 mmHg, peripheral AI of 100%, and central AI of 40% may be preliminary values in adult subjects.
