Diabetes, but not the metabolic syndrome, predicts the severity and extent of coronary artery disease in women.

BACKGROUND: Previous studies have suggested that diabetes and metabolic syndrome are significant risk factors for coronary artery disease (CAD). However, in women, their relative importance remains controversial. AIM: To evaluate risk factors for CAD in women and their association with the severity and extent of coronary angiographic findings. METHODS: We clinically evaluated 243 consecutive female patients with chest pain who underwent coronary angiography. The location and extent of coronary artery occlusions were assessed using the modified Gensini index. RESULTS: Compared with women with normal coronary arteries (n = 90), those with CAD (n = 153) reported less physical activity (p = 0.001), and had higher prevalences of diabetes (p = 0.046), hypertension (p = 0.002), and the metabolic syndrome (p = 0.001). They also had lower HDL cholesterol levels (p = 0.017), higher levels of triglycerides (p = 0.005), and higher fasting plasma glucose (FPG) (p < 0.001). Physical activity, FPG, serum triglycerides and HDL-cholesterol, but not the metabolic syndrome, were independent predictors of CAD. A score combining the extent and severity of angiographic findings was significantly higher in women with diabetes (p = 0.007), hypertension (p = 0.010) and FPG >or=100 mg/dl (p = 0.031), but showed no association with the metabolic syndrome. In a multivariate linear regression analysis, diabetes was an independent predictor of the extent and severity of angiographic score (p = 0.013). DISCUSSION: Diabetes, fasting plasma glucose and hypertension, but not the metabolic syndrome, were associated with severity of coronary angiographic findings in these women.

[Meningitis due to Streptococcus bovis type II].

Meningitis due to Streptococcus bovis is rare. Only 14 cases having been reported in the English literature. All patients (including the patient described) had an underlying disease or were treated by pharmacological agents that predisposed the patient to the infection. Most were treated by monotherapy with penicillin G (or amoxicillin) and recovered. We describe a 74-year-old woman who had splenectomy as treatment for hairy cell leukemia 6 months before hospitalization for meningitis and sepsis by S. bovis type II. She was successfully treated with intravenous amoxicillin. There was neither evidence of endocarditis nor carcinoma of the colon. Although the association between S. bovis meningitis and endocarditis or carcinoma of the gastrointestinal tract is not well established, we recommend a full work-up for GI malignancy and endocarditis in every patient with S. bovis meningitis.

[Cerebellar infarction, clinical presentation, diagnosis and treatment].

Cerebellar infarction is relatively infrequent and accounts for about 2% of all strokes. Its clinical presentation and course are variable. It may resemble vestibulitis in mild cases, but the presentation may be more dramatic in other cases. Cerebellar infarction may cause life-threatening complications such as acute hydrocephalus or brain stem compression, resulting from their mass effect in the posterior fossa or extension of the infarct to the brain stem. Clinical features alone are insufficient for the diagnosis and for follow-up of patients with cerebellar infarction. However the advent of CT and MRI and their availability enable early diagnosis of cerebellar infarction, and early recognition of the development of acute hydrocephalus or brain stem compression which require surgical decompression. The prognosis of most cases is good when treatment is appropriate.

Left pleural hemorrhagic effusion. A presenting sign of thoracic aortic dissecting aneurysm.

Left hemorrhagic pleural effusion was the presenting sign of painless aortic dissecting aneurysm in two elderly hypertensive patients. Computed tomography (CT) of the chest revealed the aneurysmal dilatation of the thoracic aorta and an intimal flap connecting its descending part with the left pleural space. The patients were treated conservatively with blood transfusions and drugs directed to control blood pressure. The first reported 71-year-old patient remains in stable condition for 16 months without evidence of recurrent active aortic dissection. The second 85-year-old patient remained in stable condition for 28 days, but finally had a second fatal episode of dissection into the left pleural space. The differential diagnosis of nontraumatic left hemorrhagic pleural effusion in an elderly hypertensive patient should include dissecting aneurysm of the descending thoracic aorta and CT of the chest should be performed as the next preferable diagnostic procedure.
