Carcinoma of the prostate is a common malignancy affecting elderly men. Lung metastasis from prostate cancer occurs frequently, but tumor metastasis to the central bronchi that clinically mimics primary bronchogenic carcinoma are very rare. We report a 73-year old man with endobronchial metastasis from prostatic carcinoma presented with respiratory symptom cough. Diagnosis of issues taken from materials which were used for bronchoscopic biopsy and prostate biopsy and immunohistochemical staining for prostate specific antigen(PSA) confirmed a case of endobronchial metastasis from prostatic carcinoma. Hormonal therapy(LHRH agonist) was applied to this patient.

We report a case of 15-year-old man with beneficial effects of short term growth hormone treatment presenting with cardiomyopathy combined with neuromuscular dystrophy. Transthoracic echocardiography revealed that LV chamber was markedly dilated and global LV systolic function was severely reduced. The findings of electromyography were compatible with neuromuscular dystrophy. Under the impression of cardiomyopathy combined with neuromuscular disease, maximal medical treatments such as inotropic agents, diuretics and ACE inhibitor were tried but we could not attain remarkable clinical improvement. Finally, we started growth hormone injection and after treatment for 3 months, we could attain remarkable clinical and hemodynamic improvement without any side effect.

Atherosclerosis is the most severe problem in the high-pressure systemic circulation and similar changes also occur in the high-pressure loading valve. This study was designed to test the hypothesis that early atherosclerosis, induced by a high cholesterol diet in rabbits, is characterized by significant ultrastructural change in the elastic laminae of the aortic valve. However, it is not known whether this process is also taking place in the cardiac valve at the early stage of atherosclerosis. Animals were fed either a high cholesterol diet (n = 5) or a control diet (n = 5) for 10-12 weeks. Histologic analysis demonstrated that subendothelial thickening and foam-cell infiltration were evident in the arterialis of aortic valves. Confocal microscopy revealed an altered pattern characterized by fragmentation and disorganization of the arterialis elastic laminae of hypercholesterolemic valves. Computerized digital analysis of the images obtained by confocal scanning microscopy demonstrated that compared to normal valves, the arterialis elastic laminae of hypercholesterolemic valves decreased in percentage of their elastin content (29.03 +/- 1.10% vs. 42.94 +/- 1.35%, p = 0.023). Immunohistochemical staining for matrix metalloproteinase-3 (MMP-3) revealed MMP-3 immunoreactivity was increased in hypercholesterolemic valves, predominantly in the arterialis. This study demonstrated that early atherosclerosis, induced by a high cholesterol diet in rabbits, is characterized by significant ultrastructural change in the elastic laminae of the aortic valve. The arterialis endothelium of the aortic valve may be a more atherosclerosis-prone area compared with the ventricularis. The presence of ultrastructural defect in the elastic laminae may play a role in chronic degenerative change and a resultant valvular dysfunction.

BACKGROUND AND OBJECTIVES: Thrombospondin-1 (TSP-1) is associated with atherosclerosis in animals with diabetes mellitus (DM). But, no study has investigated the role of TSP-1 in human atherosclerosis. This study investigated the relationship among plasma TSP-1 concentration, DM, and coronary artery disease (CAD). SUBJECTS AND METHODS: The study involved 374 consecutive subjects with suspected CAD, who had undergone coronary angiography to evaluate effort angina. Patients were divided into four groups as follows: DM(-) and CAD(-), DM(-) and CAD(+), DM(+) and CAD(-), and DM (+) and CAD(+). RESULTS: We found that plasma TSP-1 levels were higher in patients with DM(+) and CAD(+) (n=103) than those in other patients (n=271) (p<0.01). A multivariate analysis showed that male gender {odds ratio (OR), 2.728; 95% confidence interval (CI), 1.035-7.187}, high density lipoprotein-cholesterol (OR, 0.925; 95% CI, 0.874-0.980), glycated hemoglobin (OR, 1.373; 95% CI, 1.037-1.817), and plasma TSP-1 (OR, 1.004; 95% CI, 1.000-1.008) levels were independently associated with the presence of CAD in patients with DM. CONCLUSION: Plasma TSP-1 levels were higher in patients with DM(+) and CAD(+) than those in other patients, and plasma TSP-1 levels were independently associated with the presence of CAD in patients with DM. These findings show a possible link between human plasma TSP-1 concentration and CAD in patients with DM.

OBJECTIVE: To evaluate the effectiveness of intensive neurodevelopmental treatment (NDT) on gross motor function for the children having developmental delay (DD), with or without cerebral palsy (CP). METHODS: Forty-two children had intensive NDT three times weekly, 60 minutes a day, for 3 months, immediately followed by conventional NDT once or twice a week, 30 minutes a day, for another 3 months. We assessed Gross Motor Function Measure (GMFM) over three time points: before conventional NDT, before and after intensive NDT, and after 3 months of additional conventional NDT. RESULTS: The GMFM score in DD children significantly improved after intensive NDT, and the improvement maintained after 3 months of conventional NDT (p<0.05). The children were further divided into two groups: DD with CP and DD without CP. Both groups showed significant improvement and maintained the improvements, after intensive NDT (p<0.05). Also, there was no significant difference in treatment efficacy between the two groups. When we calculate the absence rate for comparing the compliance between intensive and conventional NDT, the absence rate was lower during the intensive NDT. CONCLUSION: Intensive NDT showed significantly improved gross motor function and higher compliance than conventional NDT. Additionally, all improvements were maintained through subsequent short-term conventional NDT. Thus, we recommend the intensive NDT program by day-hospital centers for children with DD, irrespective of accompanying CP.

Basaloid squamous carcinoma is a rare, pooly differentiated variant of squamous cell carcinoma. It occurs in various sites, including the upper digestive tract, the esophagus, lung, anus, cervix and thymus. It has been postulated that basaloid carcinoma may arise from outside of the anal canal, such as at where the cloacogenic embryologic cells rest, the squamous metaplastic epithelium, or the totipotential basal cells. This tumor is a distinct entity that should be carefully distinguished from basal cell carcinomas of the anal canal, which is a condition that has a very good prognosis, and anal or perianal squamous cell carcinomas, which have a different path of spread and they vary considerably in their behavior. We report here on a patient with basaloid squamous carcinoma in the distal rectum that manifested as multiple submucosal lesions, and the patient presented with abdominal pain and blood tinged stool.

Lipoma arborescens is a villous proliferation of fatty tissue in the synovial membrane, and known causes are trauma, meniscal injury, inflammation, infection, degenerative change, tumor, and so forth. The reported cases are extremely rare. We report a case of lipoma arborescens developed in all compartments of the knee joint, and treated well with arthroscopic surgery.

Primary gastrointestinal lymphomas are quite rare with the stomach and small bowel being the most frequent site. Colon involvement is observed in only 10~20% of all gastrointestinal lymphomas. A colonic lymphoma presents with non-specific abdominal pain, weight loss, a change in bowel habits, bleeding, intestinal obstruction, intussusception and a palpable mass. A colonic lymphoma can be indicated using a barium enema, abdominal CT and colonoscopy. The correct diagnosis is obtained by a colonoscopic biopsy. We report a case of primary colonic non-Hodgkin's lymphoma with peritoneal carcinomatosis and a right pleural effusion.

Chronic infection and inflammation have recently been implicated as important etiologic agents for atherosclerosis in general and, in particular, ischemic heart disease. Several agents have been suggested as possible candidates for the chronic inflammation including cytomegalovirus, Helicobacter pylori and Chlamydia pneumoniae. We hypothesized that a vascular infection with C. pneumoniae may induce a chronic inflammatory reaction in the host vascular tissue and activated inflammatory cells may express inflammatory mediators such as cyclooxygenase-2 (COX-2) and matrix metalloproteinases (MMPs). At first, we evaluated the relationship between C. pneumoniae infection and atherosclerosis indirectly by serologic study, and then, to confirm our hypothesis, we performed an immunohistochemical study of atherosclerotic plaques. The seropositive rate of anti-Chlamydia pneumoniae IgG was higher in the disease group (Group I, 59.8%, n = 254) than in the negative control group (Group III, 47.4%, n = 97) (p = 0.041), but the anti-Chlamydia pneumoniae IgA was not different in seropositivity between the two groups (Group I, 64.6%; Group III, 57.7%). The simultaneous seropositive rates of both IgG and IgA were 56.7% in Group I and 43.3% in Group III (p = 0.033). In subgroups without the conventional risk factors of atherosclerosis, these findings were more prominent. Furthermore, we performed immunohistochemical staining on the atherosclerotic aortic tissues obtained from patients that were seropositive to C. pneumoniae (n = 5), by using antibodies to C. pneumoniae, COX-2, and MMP-9. The immunoreactivity for COX-2 and MMP-9 increased in the atherosclerotic plaques itself, predominantly in the surrounding area of immunoreactive C. pneumoniae. These findings support our hypothesis and C. pneumoniae may participate in a pathogenetic mechanism for atherogenesis or progression of atherosclerosis. The present study may open a promising perspective concerning future therapeutic trials of chronic inflammation related atherogenesis under pathophysiological conditions.

Posterior epidural migration of a lumbar intervertebral disc fragment (PEMLIF) is uncommon because of anatomical barriers. It is difficult to diagnose PEMLIF definitively because of its relatively rare incidence and the ambiguity of radiological findings resembling spinal tumors. This case report describes a 76-year-old man with sudden-onset weakness and pain in both legs. Electromyography revealed bilateral lumbosacral polyradiculopathy with a mass-like lesion in L2-3 dorsal epidural space on lumbosacral magnetic resonance imaging (MRI). The lesion showed peripheral rim enhancement on T1-weighted MRI with gadolinium administration. The patient underwent decompressive L2-3 central laminectomy, to remove the mass-like lesion. The excised lesion was confirmed as an intervertebral disc. The possibility of PEMLIF should be considered when rim enhancement is observed in the epidural space on MRI scans and electrodiagnostic features of polyradiculopathy with sudden symptoms of cauda equina syndrome.
