A systemic treatment of granulocyte-colony stimulating factor (G-CSF) is known to improve healings of damaged tissues. However, recent studies suggested local actions of G-CSF on the healing processes of damaged tissues. We investigated the treatment effect of locally injected G-CSF and compared to that of systemically injected G-CSF in a rat model. A wound was created on the rat dorsum and treated either by local injection or by systemic injection of G-CSF. Wound healing rate, deposition of collagen, and gene expression were evaluated. G-CSF receptor (G-CSFR) protein was detected by Western blotting. The wound healing rate in the local injection group was significantly higher than that in the systemic injection group at days 9 and 15; it was also significantly higher than that in the control group at days 3, 9, and 15. The expression of G-CSFR protein in wound tissues was higher than in normal skin tissues. The local injection of G-CSF is more effective than systemic injection of G-CSF in promoting wound healing, which may implicate the local action of G-CSF treatment in wound healing processes.

Percutaneous vertebroplasty (PVP) is a minimally invasive surgical treatment for patients with osteoporotic vertebral compression fracture (OVCF) and can rapidly alleviate pain, improve mobility, and stabilize the vertebrae. However, it has the potential to cause complications such as cement embolism. A 55-year-old female presented with pain in the lumbar region as a chief complaint. PVP was performed after diagnosis of acute OVCFs at L4 and L5. No abnormal symptoms were reported after surgery, but a large cement embolism was observed in her right atrium and ventricle. After discussion in a multi-disciplinary team, the large cement embolism was successfully removed by a combination of endovascular procedure and an inferior vena cava exploration. Surgeons must consider the possibility of intra-cardiac cement embolism after PVP. A hybrid approach of an endovascular procedure and a vascular surgery may be a reasonable treatment option to minimize the surgical procedure in cases of a large intra-cardiac cement embolism.

Femoral artery pseudoaneurysm (FAP) is one of the most troublesome groin complications related to femoral arterial access during invasive cardiovascular procedures. Ultrasound-guided compression is the initial treatment for FAP. Here, we describe the case of a 65 year-old female who developed significant deep vein thrombosis (DVT) following ultrasound-guided compression of FAP after percutaneous coronary intervention. She was successfully treated with anti-coagulation medications. This case, along with a brief review of the literature, should remind physicians of the possible occurrence of delayed vascular complications, such as DVT, after ultrasound-guided compression of FAP.

Femoral artery pseudoaneurysm (FAP) is an uncommon but potentially serious vascular complication that may develop after cardiac and peripheral angiographic procedures. Here we describe the case of a 75-year-old female who presented with a life-threatening bleeding episode due to an FAP 4 days after diagnostic coronary angiography, which was treated with a percutaneous thrombin injection and transient balloon occlusion of the femoral artery during thrombin injection. This case reminds us of the importance of close observation and proper evaluation for complications, even if the risk of bleeding complications is low. Furthermore, although ultrasound-guided compression and a percutaneous thrombin injection are the standard treatment for FAP, this case demonstrates that transient balloon dilation during the percutaneous injection of thrombin is an important treatment option in cases of a wide-necked pseudoaneurysm in which the risk of thrombin escape is high.

Hyperphosphatemia is an unusual manifestation in patients with multiple myeloma without a significantly reduced glomerular filtration rate. Serum phosphate may be falsely elevated when a large amount of paraproteins is present in the serum, because ultraviolet light absorbance is elevated with the phosphomolybdate ultraviolet assay, which is most commonly used for serum phosphate measurement. This pseudohyperphosphatemia can be confirmed by deproteinization of the serum of patients. We report a case of multiple myeloma presenting with spurious hyperphosphatemia revealing pseudohyperphosphatemia by deproteinization of serum using sulfosalicylic acid.

BACKGROUND AND OBJECTIVES: Few studies have invasively assessed diastolic functional reserve and serial changes in left ventricular hemodynamics in euvolemic patients with exertional dyspnea. In this study, sequential changes in left ventricular end-diastolic pressure (LVEDP) to leg-raise exercise were measured invasively in patients with early heart failure with preserved ejection fraction (HFpEF) to determine the association between these serial changes and echocardiographic results or clinical features. SUBJECTS AND METHODS: During their hospital stay, 181 patients with early HFpEF underwent left cardiac catheterization, coronary angiography, and transthoracic echocardiography (TTE). Leg-raise exercise was performed in two stages: during cardiac catheterization and again during TTE. RESULTS: Compared with the initial values, all the invasively measured LVEDP values increased significantly during the leg-raise exercise, whereas the septal e/e' ratio remained unchanged. Active leg-raise led to increased LVEDP, which caused dyspnea. The severity of symptoms correlated with the level and extent of changes in LVEDP. At the end of active leg-raise, LVEDP decreased in 40 patients (22.1%), who were younger and had significantly lower e/e' ratios. On multivariate analysis to predict the response of LVEDP to active leg-raise, age and the septal e/e' ratio remained significant predictors. CONCLUSION: Despite having similar LVEDP values at rest, patients may respond to exercise with different LVEDP levels and clinical manifestations, depending on their diastolic capacity. The leg-raise exercise in early HFpEF can elucidate individual diastolic profiles, and the LVEDP response to the leg-raise test may serve as a useful criterion in stratifying patients with early HFpEF with respect to functional reserve.

Arterial hypertension following blunt abdominal trauma is a rare complication that can be induced by compression of the renal parenchyma due to a perirenal or subcapsular hematoma or adrenal hemorrhage. A 63-year-old woman was admitted after blunt abdominal trauma. Abdominal computed tomography (CT) revealed a right renal subcapsular hematoma and right adrenal gland hematoma. The patient developed hypertension during conservative treatment. Pheochromocytoma, renovascular hypertension, adrenal adenoma, thyroid disease, and other causes of secondary hypertension were excluded. On following the patient, her blood pressure normalized spontaneously without prescribing any antihypertensive medications. The renal subcapsular hematoma and adrenal hemorrhage regressed progressively as the blood pressure normalized. We report this case to make physicians aware that transient hypertension can develop in patients with blunt abdominal trauma, and to prevent the use of unnecessary antihypertensive medications.

BACKGROUND/AIMS: Long-term Helicobater pylori infection results in atrophic gastritis and intestinal metaplasia, and increases the risk of gastric cancer. However, it is still controversial that eradication of H. pylori improves atrophy or metaplasia. Therefore, we investigated histological changes after the H. pylori eradication in patients with atrophy or metaplasia. METHODS: One hundred seven patients who received successful eradication of H. pylori infection in Hanyang University, Guri Hospital from March 2001 to April 2006, were enrolled. Antral biopsy was taken before the eradication to confirm the H. pylori infection and grade of atrophy or metaplasia by updated Sydney System. After a certain period of time, antral biopsy was repeatedly taken to confirm the eradication and investigate histological changes of atrophy or metaplasia. RESULTS: Mean age of the patients was 55.3+/-11.3, and average follow-up period was 28.7+/-13.9 months. Endoscopic diagnosis included gastric ulcer, duodenal ulcer, non-ulcer antral gastritis. Atrophy was observed in 41 of 91 and their average score was 0.73+/-0.92. After the eradication of H. pylori, atrophy was improved (0.38+/-0.70, p=0.025). However, metaplasia which was observed in 49 of 107, did not significantly improve during the follow-up period. Newly developed atrophy (7 of 38) or metaplasia (18 of 49) was observed in patients who without atrophy or metaplasia initially. Their average scores were slightly lower than those of cases with pre-existing atrophy or metaplasia without statistical significance. CONCLUSIONS: After the eradication of H. pylori infection, atrophic gastritis may be improved, but change of intestinal metaplasia is milder and may take longer duration for improvement.

BACKGROUND: The hospital-acquired pneumonia is the most common nosocomial infection. Recently, the Acinetobacter baummannii infections are rapidly increasing, especially the frequency of Multi-drug resistant A. baumannii. Therefore we assessed clinical features and prognosis of patients in the ICU with Multi-drug resistant A. baumannii from the sputum culture using the Clinical Pulmonary Infection Score(CPIS). METHODS: The medical records of 43 patients with Multi-drug resistant A. baumannii from sputum culture who were suspected had clinically pneumonia and admitted to the ICU from January 2000 to July 2002 were retrospectively analyzed. RESULT: 19 patients were CPIS greater than 6 and 24 patients were CPIS less than or equal to 6. Mean age for the former was 71+/-11 years old, and the latter was 61+/-19 years old. The mean APACHE II score on admission and on sputum study was not different between two groups(17.4+/-5.7 vs 18.5+/-6.1, p=0.553, 20+/-6 vs 17+/-8, p=0.078). But the mortality rate was 73.7% for the former, and 16.7% for the latter(p<0.001). CONCLUSION: In ICU patients who had clinically suspected pneumonia with sputum culture positive for Multi-drug resistant A. baumannii, the mortality was significantly higher if CPIS was greater than 6.
