[The current clinical spectrum of pulmonary thromboembolism].

BACKGROUND. Mortality in pulmonary thromboembolism (PTE) decreases considerable when it is diagnosed early. The suspicion based on clinical and complementary data is essential for an early diagnosis. METHODS. Retrospective review of the clinical features in patients diagnosed of PTE in an Internal Medicine department from January 1993 to December 1999. RESULTS. A total of 117 patients with PTE were identified. The median age was 68.8 years. Sixty-six patients (56.4%) had one or more risk factors for PTE. The most common risk factor was immobilization (37.6%). Dyspnea was the most common symptom (74.4%) and tachypnea the most common sign (66.7%). Fever/low grade fever and leukocytosis were present in 16.2% and 31.6% of patients, respectively. Respiratory failure, alkalosis and hypocapnia were present in 44.4%, 38.5% and 47% of patients, respectively. An alveolar-arterial oxygen gradient > 20 mmHg was demonstrated in 96.6% of patients. Chest radiographs and electrocardiograms were normal in 52.1% and 23.9% of patients, respectively. A vein echo-duplex of the lower limbs demonstrated deep vein thrombosis (DVT) in 52.1% of patients. The hospital mortality rate was 6.8%. CONCLUSIONS. PTE still affects older patients mainly and frequently known risk factors are not detected. The presence of fever/low grade fever and/or leukocytosis does not rule out PTE. Both chest radiographs and electrocardiograms may be normal. Not demonstrating DVT in the lower limbs by the vein echo-duplex does not rule out PTE. The hospital mortality rate has not decreased considerably in the last few years.

[Primary antiphospholipid syndrome: characteristics and course of a series of 17 cases].

BACKGROUND: Primary antiphospholipid syndrome (APS) is a thrombophilic disorder which is not associated with connective tissue diseases or with other diseases. METHOD: Retrospective review of patients diagnosed of primary APS in an Internal Medicine service between January 1996 and December 2000. RESULTS: We identified 17 patients with primary APS. The most common presenting manifestations were deep vein thrombosis (7 cases) and ischemic stroke (3 cases). Eleven patients (65%) had vein thrombosis, 4 (24%) arterial thrombosis and no patient had both types of thrombosis. The 15 patients with thrombosis received treatment with indefinite oral anticoagulation (INR between 2.5 and 3.5). There was no recurrence of thrombosis or major hemorrhagic complications after a median follow-up time of 36 months (range 10-52 months). CONCLUSIONS: The most common presenting manifestation of primary APS is deep vein thrombosis. Venous thrombosis is more frequent than arterial thrombosis. The occurrence of both types of thrombosis seems to be exceptional. Long-term oral anticoagulation is an effective and safe treatment to prevent the recurrence of thrombosis in patients with primary APS.

Brucellar spondylitis and meningoencephalitis: a case report.

Brucellosis, a zoonosis with a worldwide distribution, is a systemic infection that can present with involvement of both nervous and musculoskeletal systems. We report a case of spondylitis and meningoencephalitis and describe the clinical features, and difficulties in treatment. Osteoarticular complications of brucellosis are common but involvement of the nervous system is rare and it should be included in the differential diagnosis of any obscure neurologic disorder.

[Differences between tuberculous spondylitis and brucellar spondylitis].

OBJECTIVE: To identify potential differences in the clinical and laboratory characteristics between tuberculous spondylitis (TS) and brucellar spondylitis (BS). PATIENTS AND METHODS: Retrospective study of patients with TS and BS diagnosed in our hospital between january 1992 and december 1998. RESULTS: TS was diagnosed in 17 patients and BS in 10 patients. In our series, a higher delay in the diagnosis (27.9 +/- 24.6 vs. 16 +/- 5.6 weeks, p = 0.02) was found in TS. There was a higher frequency, but without stadistic significance, of immunosuppression, one or several paravertebral or epidural abscesses, spinal cord compression, anemia and an elevated erythrocyte sedimentation rate in TS, and a higher frequency of fever/febricule and residual vertebral pain in BS. Lumbar location was the most frequent in both groups (58.8% in TS and 70% in BS). CONCLUSIONS: It is possible that there were some differences in the clinical and laboratory characteristics between TS and BS which may be an aid in the differential diagnosis of both entities and orient the empirical treatment in these cases without a definitive microbiological diagnosis or while awaiting the diagnostic confirmation.

[Lung sarcoidosis following instillation of mitomycin C in the urinary bladder].

Intravesical prophylaxis against recurrence of urinary bladder carcinomas using mitomycin C (MMC) has proved to be and effective treatment with few side effects. Previously only two cases of lung toxicity after instillation of MMC into the urinary bladder has been described. We report a 65-year-old man in whom lung sarcoidosis occurred after intravesical administration of MMC. This association has not been reported to date. The clinical picture and the pathogenesis of this lung disease are discussed.

[Giant-cell arteritis: a descriptive study in southwestern Spain].

OBJECTIVE: To study the clinical and laboratory features of a series of patients with giant cell arteritis (GCA) or temporal arteritis in south-western Spain (Extremadura). PATIENTS AND METHODS: Retrospective study of 25 patients with GCA diagnosed by temporal artery biopsy between 1990 and 1998. RESULTS: Nine patients were males and 16 (64%) females. Sixteen cases (64%) presented polymyalgia rheumatica (PMR). Other clinical findings were: fever/febricula (64%), constitutional syndrome (64%), new headache (96%), visual symptoms (48%), jaw claudication (17%) and abnormal temporal arteries (17%). All patients had an ESR of more than 50 mm/hour and a raised C-reactive protein. Thirteen patients (52%) had anemia (hemoglobin level < 12 g/dl). Eleven cases (44%) presented a platelet count higher than 400,000/mm3. Four patients (16%) had an elevated AST and/or ALT levels and 8 patients (32%) had an elevated GGT and/or alkaline phosphatase levels. In patients with PMR, there was a higher frequency of constitutional syndrome (81 vs 33%, p = 0.02). In females, there was a higher frequency of anemia (75 vs 11%, p < 0.01), platelet count higher than 400,000/mm3 (75 vs 0%, p < 0.01) and elevated AST and/or ALT (25 vs 0%, p < 0.01) and elevated GGT and/or alkaline phosphatase (50 vs 0%, p < 0.01) levels. CONCLUSIONS: The clinical and laboratory features of GCA in our series of patients in south-western Spain are similar to that described in other spanish populations, with the exception of a slightly higher frequency of PMR and a lower frequency of jaw claudication and abnormal temporal arteries. In our study, the clinical picture of GCA was more severe in patients with PMR and in females.

[Pernicious anemia and other megaloblastic anemias].

OBJECTIVE: To describe the clinical and biological characteristics of a series of patients with megaloblastic anemia (MA) and to identify potential differences between patients with pernicious anemia (PA(+)) and patients with other MA (PA(-)). METHOD: Retrospective study of 50 patients with MA diagnosed in our service between 1993 and 1998. RESULTS: MA was diagnosed in 50 patients. The median age in the moment of diagnosis was 70.7 years. The causes of MA were: cobalamin deficiency (CD) in 40 cases (80%), folate deficiency (FD) in 7 cases (14%) and both deficiencies in 3 cases (6%). PA was diagnosed in 19 patients (38%). All cases showed hyper-segmented neutrophils and 41 cases (81%) macroovalocytosis. Hemoglobin level < 8 g/dl was present in 22 patients (44%). The median serum LDH level was 2.059 +/- 1.739 U/l. There was a lower frequency of female sex and a higher RDW in the group PA(+). There were no significant differences between both groups in the rest of studied features, except for the presence of antiparietal cell antibodies and anti-intrinsic factor antibodies in the group PA(+). CONCLUSIONS: CD was the most frequent cause of MA in our series. PA was the most frequent cause of CD. Most cases of MA corresponded to a severe macrocytic anemia with hyper-segmented neutrophils, macroovalocytosis and very high serum LDH level. We did not identify any clinical or biological characteristic, except for the presence of antiparietal cell antibodies and anti-intrinsic factor antibodies and a higher RDW in the group PA(+), to permit distinguish the groups PA(+) and PA(-).
