[A case of miliary tuberculosis with brain tuberculoma, following intraocular tuberculosis].

A 52-year-old woman with visual loss of her left eye consulted a ophthalmology clinic. She was conducted left vitrectomy and administered corticosteroid under the diagnosis of uveitis of unknown cause. But her visual acuity was not improved. Although re-surgery was planned, pus retention was found in her left eye. After her left eye was resected, fever and general malaise appeared suddenly. Her chest X-ray film revealed diffuse micronodular opacities. Acid-fast bacilli were detected from her sputum and identified to be Mycobacterium tuberculosis. She was diagnosed miliary tuberculosis, and then antituberculous chemotherapy consisting of 4 drugs was started. Granulomatous inflammation destructing retina and numerous acid-fact bacilli were found in histologic examination of the resected eye. This case was thought to be miliary tuberculosis disseminated from intraocular tuberculosis. After 2 months of therapy, neurologic symptoms which might be caused by brain tuberucloma appeared and deteriorated rapidly. But by adding corticosteroid to antituberculous therapy, symptoms were diminished gradually.

Gastroscopy with directed biopsy and routine x-ray examination in the diagnosis of malignancies of the stomach. A retrospective study.

The examinations were performed in 418 patients with malignancy or an ulcer of the stomach. In all cases the Cancer Registry of Norway was asked for the final diagnosis and date of death. The diagnosis of malignancy was based on histology on operated or autopsy specimens, and the surviving cases were re-examined by answering a questionnaire. At the time of the primary examination a total of 103 cases of malignancies were found, of whom 41 were women. 84 patients had not been operated on previously. Among these 7 cases of early carcinoma were found. In 19 patients a partial gastrectomy had been performed. A false diagnosis of benign lesion was given on biopsy in 2 per cent, by gastroscopy in 8, and by X-ray examination in 31 per cent. A definite diagnosis of malignancy was made correctly by the same procedures in 95, 53 and 16 per cent, respectively. After 30 months of observation 16 cases of malignant lesions were reported among the patients (315) who had an ulcer of the stomach with benign histology on directed biopsy at the primary examination. A false benign diagnosis had been made in 33 per cent of 119 with malignancy by X-ray examination, in 10 per cent by gastroscopy, and in 15 per cent by histology on biopsy. The corresponding percentages in the total material of cases with benign and malignant lesions were 10.2, 2.9, and 4.3, respectively. In cases with previous partial gastrectomy, and in those with early cancers much higher rates of false negative diagnosis of malignancy has so far been suggested in 12 per cent of cases with benign ulcers, a gastroscopical diagnosis has been suggested in 22 per cent, and a bioptical in none. A combination of diagnostic procedures provided a correct diagnosis of malignancy in 118 out of 119 patients.

Diagnosis and treatment of subclavian artery aneurysms.

The diagnostic features and operative results in 13 patients with subclavian artery aneurysms were analysed. Symptoms related to subclavian artery aneurysms were present in seven patients, whereas six patients were asymptomatic and the aneurysm was discovered incidentally on chest X-ray. Angiography was the most valuable diagnostic examination and was also necessary in planning the operation. A correct preoperative diagnosis was made in five of six patients with computed tomography. Resection of the aneurysm was performed in nine and aneurysmal exclusion in the latest four patients. Direct reconstruction was used in nine and in four cases an extra-anatomic carotico-subclavian bypass was performed. Postoperative complications arose in two symptomatic and in four asymptomatic patients (46%: two strokes, two wound infections demanding extirpation of the prosthesis in one patient, two pareses of the recurrent nerve and one postoperative haemorrhage). Operative mortality was one patient. Follow-up data was available for all patients for periods of 6 months to 14 years. The vascular graft was patent in all patients. The authors conclude that subclavian artery aneurysm must be included in the differential diagnosis of all obscure upper mediastinal masses as seen on the chest X-ray and examined with CT and angiography. Exclusion of the aneurysm with extra-anatomical reconstruction is technically easier and gives the same postoperative long-term results as resection of the aneurysm and direct reconstruction. A relatively high complication rate after operation on asymptomatic subclavian aneurysms indicates a need for re-evaluation of operative indications in asymptomatic patients.

Pseudoascites: unusual presentation of omental cyst.

An unusual case of omental cyst is described. The child initially presented with a unilocular intraperitoneal fluid collection on CT. After paracentesis, CT showed freely layering peritoneal fluid, with eventual complete resolution of fluid. CT eight months later demonstrated re-appearance of a multi-septated cystic mass. At surgery, an omental cyst was found.

Binding and redox properties of iron(II) bonded to an oxo surface modeled by calix[4]arene.

The syntheses of the parent compounds [(p-Bu(t)-calix[4]-(O)2(OR)2)Fe-L] [R = Me, L = THF, 5; R = Bu(n), L = THF, 6; R = PhCH2, L = THF, 7; R = SiMe3, L = none, 8] have been performed by reacting the protonated form of the dialkylcalix[4]arene with [Fe2Mes4] [Mes = 2,4,6-Me3C6H2]. All of them undergo one-electron oxidative functionalization. By use of different oxidizing agents, the following iron(III) derivatives have been obtained: [(p-Bu(t)-calix[4]-(O)2(OR)2)Fe-X] [X = Cl, R = Me, 9; X = I, R = Me, 10] and [(p-Bu(t)-calix[4]-(O)2(OR)2)2Fe2(mu-X] [X = O, R = Me, 11; X = O, R = Bu(n), 12; X = S, R = Me, 13], 9 and 10 being particularly appropriate for a further functionalization of the metal. The last three display typical antiferromagnetic behavior [J = -78.6 cm-1, 11; J = -64.1 cm-1, 13]. In the case of 7 and 8, the reaction with O2 led to the dealkylation of one of the alkoxo groups, with the formation of a dimeric iron(III) derivative ([mu-p-Bu(t)-calix[4]-(O)3(OR))2Fe2] [R = PhCH2, 14; R = SiMe3, 15] [J = -9.8 cm-1]. The reaction of the parent compounds with ButNC and diazoalkanes led to the formation of [Fe=C] functionalities supported by a calix[4]arene oxo surface. The following compounds have been isolated and characterized: ([p-Bu(t)-calix[4]-(O)2(OR)2)Fe=CNBut] [R = SiMe3, 16, nu CN = 2175 cm-1], ([p-Bu(t)-calix[4]-(O)2(OR)2)Fe=CPh2] [R = Me, 17; R = PhCH2, 18; R = SiMe3, 19]. The three carbene complexes 17-19 display quite an unusual high-spin state, which is a consequence of the formation of a weak pi interaction between the metal and the carbene carbon, as confirmed by the extended Hückel calculations. The carbene functionality has been removed from the iron center in the reaction with O2 and HCl. The proposed structures have been supported by X-ray analyses of complexes 8, 9, 12, 14, 16, 17, and 19.

Clinicopathological correlation in a case of painful ophthalmoplegia: Tolosa-Hunt syndrome.

A case of painful ophthalmoplegia due to idiopathic granulomatous involvement of the superior orbital fissure (Tolosa-Hunt syndrome) is described. The clinical features of recurrent pain, ocular motor nerve palsies and proptosis correlated well with the eventual demonstration of an enhancing mass in the region of the cavernous sinus. Removal of the lesion led to a resolution of the clinical picture and demonstration of a non-caseating granuloma with no other detectable cause. The original observation of Tolosa was thus re-affirmed.

Crystallization of a type III chloramphenicol acetyl transferase.

A type III variant of chloramphenicol acetyl transferase was purified from Escherichia coli and crystallized in the presence of cobaltic hexamine chloride and 2-methyl-2, 4-pentandiol. Two crystal forms were obtained, one of which proved to be suitable for high-resolution X-ray diffraction studies. The space group of this form is R32 with aR = 74.5 A, alpha R = 92.5 degrees, with a monomer (Mr 25,000) in the asymmetric unit. The crystals diffract to 1.7 A resolution. The crystal symmetry has led to a re-evaluation of the oligomeric symmetry of the enzyme and the proposal that it is a trimer rather than a tetramer, the quaternary structure predicted previously from studies of the association of hybrid s subunits.

Relationship between inflammation and joint destruction in early rheumatoid arthritis: a mathematical description.

BACKGROUND: The relationship between inflammation and joint destruction in rheumatoid arthritis (RA) has not been unequivocally characterised. Joint destruction may result from the cumulative inflammatory burden over time, modified by an individual constant factor. OBJECTIVE: To test the hypothesis that the relationship between radiological progression and inflammation can mathematically be expressed as: [equation: see text] where Re is a factor that varies from person to person. METHODS: Clinical data and radiographs of 76 patients with early RA receiving different disease modifying antirheumatic drugs were analysed. Radiographs were quantified using the modified Larsen score and the "X-Ray RheumaCoach" software. The cumulative inflammatory burden was estimated by the time integrated 28 joint Disease Activity Score (DAS28), calculated as the area under the curve. RESULTS: 76 patients with early RA who started treatment with methotrexate (n = 20), sulfasalazine (n = 37), or oral gold (n = 19) monotherapy were evaluated. The mean (SEM) DAS28 decreased from 4.6 (0.1) at baseline to 2.3 (0.1) after 2 years. The mean (SEM) DeltaLarsen score from baseline to year 2 was 10.3 (1.5). Correlation between cumulative inflammation and radiographic change was poor. In contrast, when calculating a person's factor Re in year 1 ( Re 1) and year 2 ( Re 2), a strong and significant correlation (r = 0.58, p<0.000001) was seen between Re 1 and Re 2. CONCLUSIONS: Joint destruction is the result of the cumulative burden of inflammation over time, modified by an individual factor Re that remains relatively constant over the first 2 years of observation. The data support a mathematical model that expresses the interrelationship between inflammation and joint destruction.
