Back Pain Secondary to Brucella Spondylitis in the Lumbar Region

Brucellosis is a systemic, infectious disease caused by the bacterial genus Brucella and a common zoonosis that still remains a major health problem in certain parts of the world such as the Mediterranean region, the Middle East, and Latin America. It may involve multiple organs and tissues. Osteoarticular involvement is the most frequent complication of brucellosis, in which the diagnosis of brucellar spondylitis is often difficult since the clinical presentation may be obscured by many other conditions. There are only a few reports on brucellar spondylitis in Korea. Here, we report a case of spondylitis due to brucella in an elderly male.

Sonographically Guided Alcohol Injection in Painful Stump Neuroma

Stump neuroma is a common cause of pain from disorganized proliferation of nerve fascicles occurring after limb amputation. Ultrasound guided alcohol injection in painful stump neuroma has been tried as a new treatment approach. Herein, we report 2 male patients, who had traumatic amputation and claimed severe and diffuse burning pain in the stump area. Neuroma at the distal end of an amputated nerve was clearly identified on sonography. The patients gradually developed increasing severe pain that could not be managed with conservative care. They were treated with neurolysis using alcohol solution. Using ultrasonographical guidance, 1.2 ml of 100% dehydrated alcohol was injected into the nerves proximal to neuroma. No complications occurred. The patients were initially pain free. After a few months, however, their stump pain recurred slightly. Repeat neurolysis was performed using 0.3 ml of 100% dehydrated alcohol. During the three months follow-up period, mild stump pain occurred but the patients did not require any analgesics.

Shoulder Joint Infectious Arthritis and Acromioclavicular Joint Osteomyelitis due to Candida

Candida species inhabit the skin and mucous membranes of healthy individuals with low virulence, and osteomyelitis due to candida is very rare. However, the incidence of invasive candidal infection caused by intravenous drug use, broad-spectrum antibiotics, and indwelling central venous catheter is increasing. A 73-year old man visited the outpatient clinic complaining of right shoulder pain that radiated to the right acromioclavicular joint. He had undergone multiple injection procedures followed by nonsteroidal anti-inflammatory drug therapy for several weeks. The ultrasonographic findings showed a heterogeneous mass around the right acromioclavicular joint, while the right shoulder MRI and the overall findings of the body bone scan were suggestive of osteomyelitis. Pathologic findings of ultrasonographically guided joint aspiration fluid showed acute and chronic nonspecific inflammation, while the tissue culture and staining revealed Candida parapsilosis.

Gender Differences Associated with Pain Patterns and Psychological Variables in Chronic Musculoskeletal Pain Patients

OBJECTIVE: To investigate gender differences in pain patterns and psychological variables among patients with chronic musculoskeletal pain. METHOD: Thirty-five male and thirty-eight female patients who visited our outpatient clinic due to chronic musculoskeletal pain were evaluated using a questionnaire survey. Chronic musculoskeletal pain was defined as pain lasting longer than 6 months. Patients were evaluated with visual analogue scale (VAS), pain site, pain duration and frequency. Beck depression inventory, state-trait anxiety index, somatization scale of symptom checklist-revised, symptom interpretation questionnaire, and pain catastrophizing scale were checked for psychological variables. Correlations among each variable were evaluated statistically. RESULTS: Female patients with chronic musculoskeletal pain recorded higher scores on number of pain site, pain catastrophizing scale, rumination, magnification and catastrophic attribution than male patients (p<0.05). In female patients, VAS was correlated significantly with depression, static anxiety, somatization, catastrophizing thought. rumination, magnification, helpless, and catastrophic attribution. Pain frequency was correlated significantly with somatization, catastrophizing thought, rumination, and helpless. Number of pain site was correlated with somatization, catastrophizing thought, magnification, and helpless. The correlation between pain patterns and psychological variables was also observed in male patients, but statistically less significant than female patients. CONCLUSION: We found gender difference associated with pain patterns and psychological variables in chronic musculoskeletal pain patients. Consideration of psychological factors may be important for management in female patients with chronic musculoskeletal pain.

The Significance of p53 and K-ras Immunocytochemical Staining in the Diagnosis of Malignant Biliary Obstruction by Brush Cytology during ERCP

BACKGROUND/AIMS: Brush cytology during ERCP can provide a pathologic diagnosis in malignant biliary obstruction. K-ras and p53 mutations are commonly found in biliary and pancreatic cancers. We evaluated the diagnostic yield of brush cytology and the changes obtained by adding p53 and K-ras staining. METHODS: One hundred and forty patients with biliary obstruction who underwent ERCP with brush cytology during a 7-year period were included. The sensitivity and specificity of brush cytology only and with the addition of p53 and K-ras staining were obtained. RESULTS: Malignant biliary obstruction was confirmed in 119 patients. The sensitivity and specificity of brush cytology were 78.2% and 90.5%, respectively. The sensitivity of cytology was 77.3% at the ampulla-distal common bile duct (CBD), 92.6% at the mid common hepatic duct (CHD), and 94.7% at the proximal CBD-CHD (p<0.05); these values did not differ with the degree or the length of the obstruction. In the 97 patients who received additional p53 and K-ras staining, the sensitivity of cytology plus p53 was 88.2%, cytology plus K-ras was 84.0%, and cytology plus p53 and K-ras was 88.2%. The sensitivity of cytology plus p53 was higher than that of brush cytology only (95% confidence interval: 83.69-92.78 vs 72.65-83.65) but not that of cytology plus K-ras. CONCLUSIONS: Brush cytology for malignant biliary obstruction has a high diagnostic accuracy. Adding p53 staining can further improve the diagnostic yield, whereas K-ras staining does not.

Endoscopic Ultrasonography in Upper Gastrointestinal Subepithelial Lesions / 대한소화기내시경학회지

BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) is known for its value to characterize incidentally found subepithelial lesions, and we so reviewed our data to validate the norm. METHODS: We analyzed the records of the patients with suspected subepithelial lesions at the time of endoscopy, which was performed from Aug. 2001 to Oct. 2004. RESULTS: The data includes 622 patients (248 males) with average age of 52 years (age range 15~83 years). Extraluminal compression was noted in 10.1% of the patients. Intraluminal lesions were dominant in the stomach and their average size was 14.8 mm. The inner three wall layers were the predominant layers of origin. Mesenchymal tumors were the most frequent EUS impression. Pathologic findings were available for 88 patients and 80.7% of them were benign. Compared with the pathology, the diagnostic accuracy of EUS was 78.4%. The differentiation of malignant and benign GISTs by the EUS findings was 56.3%. Among the 60 EUS cases that had follow up data available (at mean interval of 12.2 months) and who also had less than 3 cm benign lesions, growth was detected only in 10 cases (17%). Pathology confirmed that the lesions in 3 of them were benign. CONCLUSIONS: More than 10% of the subepithelial lesions found from endoscopy were extraluminal compression. The majority of intramural lesions were benign. The EUS impression was relatively accurate and helpful for the management of upper gastrointestinal submucosal lesions.

A Case of High Grade Dysplasia in Sporadic Fundic Gland Polyp / 대한소화기내시경학회지

Fundic gland polyps (FGP) are the most common type of gastric polyps, with an incidence on endoscopy of 0.8~1.9%. They have been considered as benign lesions, without the potential for malignant transformation. High grade dysplasia and gastric adenocarcinomas associated with FGP have been described in patients with familial, as well as attenuated adenomatous polyposis (FAP). In contrast, dysplasia associated with FGP in non-FAP patients is extremely rare, and there have been no reports of sporadic FGP with high grade dysplasia in the Korean literature. Herein, we report one case of high grade dysplasia associated with sporadic FGP in a non-FAP patient treated with an endoscopic polypectomy.

Accuracy of Endoscopic Ultrasonographic Impression Compared with Pathologic Diagnosis in Gastrointestinal Submucosal Tumors / 대한소화기학회지

BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) is a valuable imaging modality for the evaluation of gastrointestinal submucosal tumor (SMT). EUS is helpful in assessing the layer of origin, tumor diameter, shape, border characteristics, and internal echo patterns of SMTs and thus makes it possible to predict histologic diagnosis with educated guess. However, some studies have found no significant differences in EUS features between benign and malignant mesenchymal tumors. By comparing EUS impressions with histologic diagnosis, we evaluated the accuracy of EUS in differential diagnosis of gastrointestinal SMTs. METHODS: 58 cases of gastrointestinal SMTs with both EUS findings and pathologic reports were compared retrospectively from August 2001 to September 2003. RESULTS: 34 patients had lesions in the stomach and 13, 8, 3 in the esophagus, duodenum, and colon respectively. Benign lesions were predominant (46 of 58). The EUS and pathologic diagnosis coincided in 46/58 (79.3%) of the cases. Use of EUS led to the correct diagnosis in 7/9 (77.8%) of malignant GISTs (gastrointestinal stromal tumor) and leiomyosarcomas. Two small malignant gastric GISTs were diagnosed as benign with EUS. CONCLUSIONS: EUS is a useful tool in the differential diagnosis of gastrointestinal SMTs and predicting malignant lesions. However, some malignant GISTs were diagnosed as benign tumor with EUS examination.

The Usefulness of Endoscopic Ultrasonography in the Diagnosis of Diseases of Liver, Biliary Tree, Gallbladder and around Distal Common Bile Duct / 대한소화기내시경학회지

BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) is now accepted as an essential tool for the diagnosis and the therapy of various gastrointestinal diseases. With regard to the biliary system, its high diagnostic sensitivity and specificity were reported recently. We assessed the clinical usefulness of EUS for the diagnosis of diseases of the liver, biliary tree, gallbladder and distal common bile duct. METHODS: We sent questionnaires about the clinical usefulness of EUS to the doctors who requested EUS examination for 32 patients with suspected diseases of the liver, gallbladder and around extrahepatic biliary tree from Aug. 2001 to Aug. 2002. We evaluated the answers and clinical characteristics of the patients. RESULTS: Patients were 17 males and 15 females with mean age of 61.8 years old. All received abdominal computed tomography (CT) before EUS and some had abdominal ultrasonography (USG) or endoscopic retrograde cholangiopancreatography (ERCP). EUS was more accurate and informative than other imaging modalities and gave definite final diagnosis for 31.2%. In 40.6%, EUS was helpful as an additional diagnostic tool. CONCLUSIONS: EUS was useful in 71.8% of the cases for the diagnosis of diseases of the liver, biliary tree, gallbladder and around distal common bile duct. EUS can be used as an important adjunct to USG, CT and ERCP.

A Case of Primary Aldosteronism with Aortic Dissection / 대한내분비학회지

Hypertension and atherosclerosis are the most important factors contributing to the development of aortic dissection. Primary aldosteronism is a rare cause of hypertension. The concurrence of aortic dissection is very rare in primary aldosteronism. However, when aortic dissection is found as a life-threatening complication of primary aldosteronism, then the diagnosis of primary aldosteronism is important because the therapeutic intervention can be curative. Only 3 cases of primary aldosteronism with aortic dissection have been reported in the literature. We report here on a case of primary aldosteronism with aortic dissection, which was treated by laparoscopic adrenalectomy. We lowered the blood pressure with antihypertensive drugs and potassium replacement was done to treat the aortic dissection. After stabilization of aortic dissection, we removed his left adrenal mass by laparoscopic adrenalectomy. Postoperatively, the patient's blood pressure has been within normal limits and the serum potassium increased to a normal level without supplementation. The aortic dissection has remained in a stable state

A Case of Primary Cardiac Non-Hodgkin's Lymphoma

Although 25 to 36% of systemic lymphoma patients develop cardiac involvement, a primary lymphoma involving only the heart or pericardium is much less common. We detected an intracavitary mass in the right atrium and right ventricle in a 73-year-old man with dyspnea on exertion and generalized edema using transthoracic and transesophageal echocardiography. A thoracotomy was performed due to a possible cardiac tamponade, and a myocardial biopsy showed a malignant non-Hodgkin's lymphoma of the diffuse large B cell type. We report a rare case of a primary cardiac lymphoma detected using a transthoracic and transesophageal echocardiography in patient presenting with a massive pericardial effusion.

Oxaliplatin and UFT, leucovorin combination chemotherapy in patients with advanced colorectal cancer / 대한내과학회지

BACKGROUND: UFT/oral leucovorin (LV) provided a safer, more convenient oral alternative to bolus i.v. 5-Fluorouracil/LV regimen for advanced colorectal cancer while producing equivalent survival. We evaluated the efficacy and safety of a combination of oxaliplatin and UFT/LV in patients with advanced colorectal cancer. METHODS: From January 1999 to December 2001, a total 28 patient with metastatic or relapsed colorectal cancer were enrolled in this study. Treatment was consisted of oxaliplatin 130 mg/m2 i.v. for 2 hours on day 1, and UFT 300 mg/m2 p.o. and LV 30 mg p.o. on day 1-21. Chemotherapy repeated every three weeks until disease progression. RESULTS: Of the 28 patients, 1 complete response and 10 partial responses were observed. The overall response rate was 39.3%. The estimated median time to progression and survival were 6.0 months and 18.2 months, respectively. Peripheral neuropathy was the most common adverse effect. But, peripheral neuropathy was mild (grade 1, 2) and reversible. From the 129 cycles analyzed, grade 3, 4 adverse effects were observed only 3% included neutropenia (1.5%), and thrombocytopenia (1.5%). There were no treatment-related deaths. CONCLUSION: This combination of oxaliplatin and UFT/oral leucovorin is active and feasible in patients with advanced colorectal cancer. The regimen deserve further evaluation in a phase III prospective study.
