BACKGROUND: Rhinovirus infection of the airways results in increased permeability of the airway vascular endothelium with the influx of plasma proteins, including lipids such as LDL. In vitro studies on the effect of oxLDL on leukocytes has shown many proinflammatory effects on multiple leukocytes. We hypothesized that oxLDL is one mechanism for recruiting granulocytes to the airways during a RV infection. Therefore, chemotaxis and transendothelial migration, in response to nLDL, was determined for these granulocytes. METHODS: nLDL was oxidized with 5mM Cu2SO4 for 20-24 hours. 3-5×10(5) cells were loaded into the Transwell filter while the chemotatic agonists were placed in the lower well for chemotaxis. Confluent monolayers on HPMEC were grown on Transwell filters for transendothelial migration. The filters were washed and eosinophils and neutrophils loaded on to the filter with the chemotatic agonist was were placed in the lower well. The wells were incubated for 3 hours. The number of migrating cells was counted on a hemocytometer. RESULTS: OxLDL, but not nLDL, is chemotatic for eosinophils and neutrophils. The level of granulocytes chemotaxis was dependent on both the concentration of LDL and its degree of oxidation. OxLDL stimulates eosinophil and neutrophils migration across HPMEC monolayers (±IL-1β preactivation) in a dose dependent manner. CONCLUSION: Increased vascular permeability during a RV infection may lead to the influx and oxidation of LDL. The resulting oxLDL. is one possible mechanism for the recruitment of neutrophils and eosinophils to the airway interstitial matrix. Once in the airways, granulocytes can further interact with oxLDL to promote airway inflammation.

The aspergillus tracheobronchitis is distinctive manifestation of invasive aspergillosis, in which infection is limited completely or predominantly to the tracheobronchial tree. It accounts for about 7 to 10 percent of cases of invasive disease. Grossly, such disease may take the mucosal exudate and obstruct partially the airway lumen or completely the occlusive mucous/fungus plugs. Microscopically, the superficial portion of the airway wall is acutely inflamed and contain fungal hyphae. However, infection is often limited to the mucosa. We report a case of aspergillus tracheobrochits in a 54 year-old man who presented cough, progressive dyspnea with wheezing, and mucus plug. Bronchoscopy showed mucosal exudate and plug.Bronchoscopic biopsy showed aspergillus hyphae and inflammation in the mucosa. He was successfully treated with itraconazole.

Apert syndrome is an uncommon, congenital disorder characterised by malformation of the skull, most often acrocephaly or oxycephaly, in association with symmetrical syndactyly of both hands and feet. It is due to disturbance in the growth of bone and soft tissue affecting principally the head, the hands and the feet. The original description was presented by Troquart in 1886, and acrocephaloyndactyly was named by Apert in 1906. Since then, more than 200 cases have been reported in the world upto 1970. Recently, we have experienced three for typical Apert syndrome and made a brief related literature review

Angiomyolipoma is considered by many authors to be a hamartoma, occurring in a sporadic form or in association with tuberous sclerosis. This lesion consists of thick walled blood vessels, smooth muscle, and mature adipose tissue in varying amounts. We have experienced a case of the angiomyolipoma composed of monotypic epithelioid cells. The patient was a 69-year-old female. Clinically, there was no evidence of tuberous sclerosis. Microscopically, the tumor was composed of polygonal cells with abundant eosinophilic granular or clear cytoplasm, pleomorphic nuclei, prominent nucleoli, and multinucleated giant cells. The tumor cells showed positive reaction for HMB45, CD68, smooth muscle actin, and S-100, and negative reaction for epithelial membrane antigen, cytokeratin, vimentin, desmin, CD34, estrogen receptor, and progesterone receptor. Ultrastructual analysis showed the presence of glycogen, mitochondria, and other microorganelles in neoplastic cells. Melanosome or premelanosome was not identified.

Pulmonary aspergillosis is classified as a saprophytic, allergic, and invasive disease. Chronic necrotizing pulmonary aspergillosis is categorized as an invasive pulmonary aspergillosis. Most invasive pulmonary aspergillosis have acute and toxic clinical features but chronic necrotizing pulmonary aspergillosis is characterized by a sub-acute infection, most commonly seen in patients with altered local defense system from preexisting pulmonary disease of in mild immunocompromised patients. Pulmonary artery aneurysm due to this infection is termed as a mycotic aneurysm, etiology of which are tuberculosis, syphilis, bacteria and fungus. We report a case chronic necrotizing pulmonary aspergillosis complicating pulmonary aneurysm is a 62 year-old man who was presented with cough, sputum, and fever. Chest radiographs showed a rapid, progressive cavitary lesion and pulmonary artery aneurysm. Angioinvastion of aspergillus was revealed by pathology after operative removal of left upper lobe containing the pulmonary artery aneurysm. He was treated with itraconazole.

Extra-pulmonary tuberculosis usually progresses as a secondary infection from pulmonary tuberculosis, and tuberculosis of the head and neck region. Tuberculosis of ocular and periocular areas, however, is a rare disease. Among ocular tuberculosis involving the adnexal structures, a few lacrimal sac tuberculosis has been reported. We recently experienced a case of lacrimal sac tuberculosis presenting as epiphora. Examination revealed bilateral nasolacrimal duct obstruction and the patient underwent endoscopic endonasal dacryocystorhinostomy. During the operation, a biopsy taken from the unhealthy looking lacrimal sac filled with caseous necrotic tissue was suggestive of tuberculosis. Histopathological features and further systemic evaluation confirmed tuberculosis. She was treated medically with anti-tubercular agents. The new opening of the lacrimal sac was patent and epiphora was resolved successfully at a year follow up. This report highlights the requirement of high suspicion of tuberculosis, even in the nasolacrimal drainage system.

Between 2008 and 2009, We found 9 new cases and 3 relapse cases, diagnosis by the clinical finding, skin smear, skin biopsy, lepromin test, ELISA for PGL-I antibody, and DNA-PCR. The obtained results were summarized as follows: 1. In 9 new cases, the mean age was 56.2 in 5 Koreans and 28.2 in 4 foreigners(Nepal, Thailand, Sri Lanka, Philippines), the types of Hansen's disease were 5 lepromatous(2 Koreans and 3 foreigners), 1 borderline(1 foreigner) and 2 tuberculoid(2 Koreans), mean BI was 3.4+, mean O.D. of PGL-I antibody was 0.445, numbers of TTC repeat are 16(2 Korean and 2 foreigners), 11(2 Koreans), 12(1 Koreans) and 13(1 Koreans), and of GACATC repeats are 4(4 Koreans) and 3(1 Korean and 4 foreigners). Among 9 new cases, 1 case has the mutation offolP1 gene. 2. All new cases had no mutation of & rpoB gene. 3. In 3 relapse cases, the mean age was 63.7, the types of Hansen's disease were 3 lepromatous(3 Koreans), mean BI was 4.0+,and mean O.D. of PGL-I antibody was 0.846, and numbers of TTC repeat were 12(2 cases), 11(1 case), and of GACATC repeats are 4(all 3 Koreans). Among 3 relapse cases, 1 case has the mutation ofrpoB gene.
