BACKGROUND: The late effects of cervical sympathectomy on the ultrastructure of the intracranial arteries of the rats have been examined. DESIGN: Unilateral cervical sympathectomy was performed to 6 rats and the changes of the middle central artery were evaluated 6 weeks later in the probands and 9 other control rats by electron microscopy. RESULTS AND CONCLUSION: Number of fibers of the muscular layer of the ipsilateral middle central artery group decreased significantly compared to the control group. (Return)

BACKGROUND: Toxic shock syndrome (TSS), which has been described as a disease of older children and mensturating women can occur in both sex and at all ages. There might be some geographical differences in the clinical presentation of the disease. DESIGN: A retrospective evaluation of 8 patients with TSS seen between September 1985 to January 1994 in the Division of Infectious Diseases is presented and compared to other series obtained from an extensive review of the literature. RESULTS: The sex ratio was equal and all the women were in postmenopausal state. Other prominent differences of our patients were eosinophilia and headache. (Return)

BACKGROUND AND DESIGN: A randomized comparative study was conducted to determine the hemodynamic influences of ionic (I) [sodium menglumine diatrizoate] contrast media (CM) which are currently used in cardiac angiography. One hundred ninetytwo patients, with suspected coronary artery disease, undergoing left ventriculography and coronary angiography were included. 101 (mean age: 51±8) received I CM and 91 (mean age: 51±9) received NI CM. The hemodynamic parameters were measured just before and within the first minute of left ventriculography. The results were statistically analyzed by paired t, unpaired t and chi-square tests. RESULTS: After left ventriculography with I CM the systolic pressure was decreased significantly (from 131±27 to 120±30 mmHg, p<0.05). NI CM did not change this parameter. Left ventricular end diastolic pressures were significantly and similary elevated after the injection of both kinds of CM (in I group from 13±7 to 16±8 mmHg and in NI group from 13±8 to 17±8 mmHg, p<0.05). While no alterations were observed with NI CM, ICM produced a prominent increase in +dP/dt (from 1316±325 to 1441±386 mmHg/sec, p<0.05). Left ventricular diastolic mechanics were negatively effected by I CM (by reducing -dP/dt from 1467±345 to 1402±366 mmHg/sec, p<0.05) but NI CM did not have any influence. CONCLUSION: Because of the negative effects of I CM, especially on left ventricular diastolic mechanics, it is concluded that, although they are much more expensive than I CM, the NI CM should be preferred in patients with left ventricular dysfunction.

BACKGROUND: Cerebrovascular disease in association with livedo reticularis is known as Sneddon's syndrome. Sneddon s original description also included hypertension as part of the triad. Majority of these patients have antiphosholipid antibodies. OBSERVATION: A case of Sneddon s syndrome characterized by headache for four years, reccurent and progressive strokes, psychomental deterioration for two years, livedo reticularis and valvular heart disease in a woman of 38 years old is reported.

BACKGROUND AND DESIGN: Necrotizing enterocolitis (NEC) is a source of morbidity and mortality among preterm infants. The pathogenesis of necrotizing enterocolitis is complex and multifactorial. Inflammatory mediator production, triggered by local hypoxia and/or bacterial toxins may represent an important mechanism of intestinal injury. Interventions such as breast feeding, steroid terapy, enteral immunoglobulin supplementation, and inflammatory madiator antagonists deserve further consideration for a reduction of the incidence of NEC.
