Article: Cholesterol granuloma: a rare benign rib tumor.
[show abstract] [hide abstract]
ABSTRACT: Rib tumors are uncommon, constituting only 5% to 10% of all bony neoplasms. Cholesterol granuloma is also rare and is described as inflammatory granulation that occurs in response to the deposition of cholesterol crystals. Cholesterol granulomas are found most commonly in the paranasal sinuses or temporal bones, but there are also rare reports of their occurrence in the peritoneum, parotid gland, lymph nodes, thyroglossal duct, kidney, liver, and spleen. Involvement of the ribs has rarely been described previously. We report a rare case of cholesterol granuloma involving the second rib of a 38-year-old-woman who presented with a slowly growing lesion of the anterior aspect of the chest.The Annals of thoracic surgery 05/2013; 95(5):1801-3. · 3.74 Impact Factor -
Article: Thoracic air-leak syndromes in hematopoietic stem cell transplant recipients with graft-versus-host disease: a possible sign for poor response to treatment and poor prognosis.
[show abstract] [hide abstract]
ABSTRACT: Bronchiolitis obliterans (BO) or bronchiolitis obliterans organizing pneumonia (BOOP) is one of manifestations of graft-versus-host disease (GVHD), a complication of hematopoietic stem cell transplantation (HSCT). Recently there are reports about thoracic air-leakage syndrome (TALS), but real incidence, clinical course, and implications of TALS remain unclear. Retrospective review of 18 TALS patients among 2,177 patients who received allogeneic HSCT between January 2000 to July 2007 was done. Clinical manifestations, treatments, and outcomes of TALS were reviewed. The incidence of TALS was 0.83% (18/2,177). The onset of TALS was mean 425.9+/-417.8 days (60-1,825 days) after HSCT, and the duration was mean 16.3+/-21 days (2-90 days). The most common types of TALS were spontaneous pneumothroax (n=14), followed by subcutaneous emphysema (n=6), pneumomediastinum (n=5), interstitial emphysema (n=2), and pneumopericardium (n=1). TALS persisted in six patients, who died during the same hospitalization. The 12 patients recovered from TALS, but only 2 survived, while others died due to aggravation of GVHD. TALS may complicate BO/BOOP and be an initial manifestation of BO/BOOP. TALS is hard to be resolved, and even after the recovery, patients die because of aggravation of GVHD. We suggest specifically in HSCT patients, when once developed, TALS seems hard to be cured, and as a result, be related to high fatality.Journal of Korean medical science 05/2010; 25(5):658-62. · 0.84 Impact Factor -
Article: Congenital hemidiaphragmatic agenesis presenting as reversible mesenteroaxial gastric volvulus and diaphragmatic hernia: a case report.
[show abstract] [hide abstract]
ABSTRACT: A 70-yr-old woman complained of left sided chest pain and non-bilious vomiting for four days after taking a gastric bloating agent for an upper gastrointestinal study. The chest radiography revealed gastric air-fluid levels and bowel loops in the left thoracic cavity. An emergency thoracotomy was performed. The abdominal organs (stomach, spleen, splenic flexure of the colon) were in the left thorax and the entire left hemidiaphragm was absent. There were no diaphragmatic remnants visible for reconstruction of the left diaphragm. We provided warm saline irrigation and performed a left lower lobe adhesiotomy. Thirteen days after surgery, the chest radiography showed improvement in the herniation but mild haziness remained at the left lower lung field. Here we present the oldest case of congenital diaphragmatic agenesis presenting with transient gastric volvulus and diaphragmatic hernia.Journal of Korean medical science 07/2009; 24(3):517-9. · 0.84 Impact Factor -
Article: The effects of sevoflurane on systemic and pulmonary inflammatory responses after cardiopulmonary bypass.
[show abstract] [hide abstract]
ABSTRACT: During reperfusion after cardiopulmonary bypass, leukocytes are retained in the lungs. The purpose of this study was to examine the effect of sevoflurane on the inflammatory responses of the lungs after cardiopulmonary bypass. A prospective, randomized clinical investigation. A university hospital. Thirty patients undergoing valve replacement surgery using cardiopulmonary bypass. Fifteen patients in whom anesthesia was maintained with sevoflurane and the priming solution was saturated with sevoflurane were randomly assigned to the sevoflurane group. Similarly, 15 patients in whom anesthesia was maintained with sufentanil and the priming solution was mixed with sufentanil were randomly assigned to the sufentanil group After induction, an arterial blood sample was obtained for the baseline leukocyte count. Blood was collected from the pulmonary artery (PA) and vein (PV) before cardiopulmonary bypass and 10 minutes after the restoration of heart beats. The leukocyte count, levels of interleukin-6, interleukin-8, interleukin-10, and tumor necrosis factor-alpha were measured. The PV/PA ratio of each parameter was determined for the assessment of inflammatory response of the lung. The leukocyte counts and plasma levels of cytokines increased more in the sufentanil group than the sevoflurane group. The PV/PA ratio of neutrophils decreased after the restoration of heart beats in the sufentanil group but was unchanged in the sevoflurane group. The PV/PA ratio of IL-6 was higher in the sufentanil group. The PV/PA ratio of interleukin-8 and interleukin-10 increased after the restoration of the pulmonary circulation in the sufentanil group but decreased in the sevoflurane group. The PV/PA ratio of tumor necrosis factor alpha increased in the sufentanil group but remained unchanged in the sevoflurane group. Sevoflurane attenuates the pulmonary sequestration of neutrophil and leukocytes and also preserves the pulmonary consumption of cytokines at the time of early pulmonary reperfusion. Sevoflurane attenuates the systemic inflammatory response induced by cardiopulmonary bypass.Journal of cardiothoracic and vascular anesthesia 05/2009; 23(5):639-45. · 1.06 Impact Factor -
Article: Short-term and intermediate-term results after unclipping: what happened to primary hyperhidrosis and truncal reflex sweating after unclipping in patients who underwent endoscopic thoracic sympathetic clamping?
[show abstract] [hide abstract]
ABSTRACT: Endoscopic thoracic sympathetic clamping (ETC) is used to treat patients with primary hyperhidrosis because it offers the potential of a reversal operation (unclipping) when severe reflex sweating (RS) occurs. Although unclipping has been reported to be effective, the short-term or intermediate-term results after unclipping are unclear. From March 2002 to October 2006, 15 (12.9%) out of 116 patients with primary hyperhidrosis, who underwent ETC, had the endoclip(s) removed as a result of RS. Fourteen patients could be followed up for more than 6 months. The patients answered a telephone interview on the severity of RS, the recurrence of the primary site, and their level of satisfaction. There was no mortality or significant morbidity encountered. On the follow-up, 9 (64%) of the 14 patients who underwent unclipping reported symptomatic recovery from RS. Of these 9 patients with early unclipping (within 4 wk after ETC), only 7 (78%) were satisfied with the outcomes. This suggests that early unclipping does not always guarantee satisfactory recovery from RS. Because early unclipping does not guarantee a full recovery in all patients, special consideration in ETC is needed to determine when to remove the clamp and how strongly to apply the clamp to achieve better results.Surgical laparoscopy, endoscopy & percutaneous techniques 11/2008; 18(5):469-73. · 1.23 Impact Factor
