TI : Does nasal irrigation enter paranasal sinuses in chronic rhinosinusitis?

EN-AB: BACKGROUND: Nasal irrigation is widely used in treating sinonasal diseases. Not only does it remove static secretions and promote mucociliary clearance, but, in chronic rhinosinusitis, nasal flush is also a potential route for topical drug administration into paranasal sinuses. A clinical study was conducted to investigate how well nasal irrigation could reach paranasal sinuses with the ostiomeatal units blocked in chronic rhinosinusitis. This study was performed to (1) assess the ability of a nasal douche and spray to deliver a solution into the paranasal sinuses in chronic rhinosinusitis and (2) compare the performance of the two techniques. METHODS: Fourteen patients, with bilateral chronic rhinosinusitis, underwent nasal irrigation with 140 mg/mL of iodinated contrast solution by 40 mL of douching using an irrigation syringe in one side, and 10 mL of spraying in the other side. A computed tomography scan was undertaken for each patient to determine the volume and the distribution of staining in the nose and paranasal sinuses. RESULTS: Only two patients had any staining, with a small amount present in a total of three maxillary sinuses (0.10 mL, 0.04 mL, and 0.13 mL). The mean volumes of paranasal sinus staining by nasal douche and nasal spray were 0.0093 and 0.01 mL, respectively. We found that the two techniques had a similar performance. Both of them delivered only a small amount of the solution, if any, into the sinuses (with a mean difference of -0.0007 mL; 95% CI, -0.02-0.02 mL; p = 0.94). CONCLUSION: Nasal douche and spray is not effective in delivering a nasal irrigation solution into paranasal sinuses in chronic rhinosinusitis. (NO 18954507)

TI : Heterozygous nonsense mutation SATB2 associated with cleft palate, osteoporosis, and cognitive defects.

EN-AB: Studies of human chromosomal aberrations and knockout (KO) mice have suggested SATB2 as a candidate gene for a human malformation syndrome of craniofacial patterning and brain development. Of 59 unrelated patients with craniofacial dysmorphism, with or without mental retardation, one 36-year-old man had a nonsynonymous mutation in SATB2. The affected individual exhibited craniofacial dysmorphisms including cleft palate, generalized osteoporosis, profound mental retardation, epilepsy and a jovial personality. He carries a de novo germline nonsense mutation (c.715C>T, p.R239X) in the exon 6 of SATB2. Expression studies showed that the mutant RNA was stable, expected to produce a truncated protein predicted to retain its dimerization domain and exert a dominant negative effect. This new syndrome is the first determined to result from mutation of a gene within the family that encodes nuclear matrix-attachment region (MAR) proteins. (NO 17377962)

TI : Radiographic manifestations of pulmonary cryptococcosis.
AU : Piyavisetpat N, Chaowanapanja P.
EN-AB: Pulmonary cryptococcosis may occur in both immunocompromised and immunocompetent hosts. The purpose of the present study was to review the radiologic findings of pulmonary cryptococcosis in King Chulalongkorn Memorial Hospital. The radiographs and computed tomography of the chests of the patients who had a diagnosis of pulmonary cryptococcosis, between 1998-2001, were retrospectively reviewed. Seven patients were included. Five were HIV infected, three had diffuse reticulonodular opacities, two (of the three) patients also had accompanying cavities; two had solely pleural effusion. Two patients were immunocompetent; one had a pulmonary nodule and another one had an endobronchial lesion and multiple pulmonary masses in the collapsed lung seen on CT scan, which were consistent with cryptococcoma. None had adenopathy. There was a difference in the radiologic manifestations between immunocompromised and immunocompetent hosts. Knowledge in radiographic features in pulmonary cryptococcosis should help radiologists to early recognize the disease and may improve the treatment outcome. (NO 16471118)

TI : MR imaging of CNS leiomyosarcoma in AIDS patients.

EN-AB: Leiomyosarcomas of the central nervous system are extremely rare; however they are becoming more prevalent in immunocompromised patients. The authors present MRI (Magnetic Resonance Imaging) of six cases of pathological proved leiomyosarcomas of the central nervous system in patients infected with human immunodeficiency virus. MR images of 4 cases of intraspinal leiomyosarcoma showed lobulated masses expanding multilevel of neural foramina with extradural and intradural extension, giving dumbbell appearance which mimic neurofibroma. Two cases of intracranial leiomyosarcoma revealed a mass at the left cavernous sinus involving prepontine cistern in one case and two lesions in the other case showing masses with dural based appearance at the region of the planum sphenoidale and the posterior aspect of the falx cerebri which mimiced a meningioma. The leiomyosarcoma should be included in the differential diagnosis of extra-axial CNS lesions in HIV-infected patients. (NO 16083180)
