OBJECTIVE To investigate whether transient ischemic attack (TIA) had an ischemic preconditioning neuroprotective effect on subsequent cerebral infarction. PATIENTS AND METHODS 232 patients with cerebral infarction were selected and divided into Group A (<55 years old), Group B (55-75 years old) and Group C (>75 years old), according to age. Each group was further divided into sub-groups A1, A...

The joints between segmental rings can withstand a certain amount of bending moment as well as axial and shear forces. Generally, in the structural analysis of tunnel segmental lining, the joints can be modeled as elastic hinges or rotational springs, and their rigidity should be demonstrated in terms of the rigidity of the joints or their rotational stiffness. Therefore, the bending moment act...

"Echoventriculography", an echocardiographic method specially developed to scan the regional function of the left ventricle, is introduced for studying left ventricular wall motion alteration in patients with acute myocardial infarction. Purposeful probe directions, a 2:1 magnification, and careful adjustment of the gain and reject levels allowed a direct echocardiographic scanning of practical...

Segmental infarction (SI) of the testis is a rare condition that can masquerade as a mass lesion, thus requiring exclusion of tumour. If clinical exams do not exclude a neoplastic lesion with certainty, orchidectomy is usually performed. A case of SI of the testis is presented; the use of frozen section of the enucleated mass demonstrated the ischaemic nature of the lesion, so avoiding orchidec...

Collapsing glomerulopathy with patchy acute cortical necrosis secondary to postpartum hemorrhage Sir, Collapsing glomerulopathy (CG) represents a distinct pattern of renal response to injury characterized by segmental to global collapse of capillaries in association with hyperplasia and hypertrophy of the visceral epithelial cells (VECs) associated with marked tubulointerstitial damage [1]. The...

Arterial thrombosis is relatively rare compared with venous thrombosis in nephrotic syndrome. However, the assessment of its pathogenesis and risk factors in individual patient with nephrotic syndrome is necessary to allow appropriate prophylactic management because it is a potentially serious problem. Hereby, with review of the literature, we report a case of a 53 yr-old man with cerebral infa...

In the absence of evidence for pneumonia or pulmonary embolus, primary pulmonary infarction has been assumed to be the cause of the syndrome of chest pain, fever, and pulmonary infiltrate on chest X-ray that commonly complicates sickle cell anaemia. To find out whether the syndrome might be due to rib infarction, 99mTc-diphosphonate bone scans were done. In the eleven episodes thus investigated...

Pulmonary haemorrhage after embolic occlusion of a pulmonary artery usually follows the infarction of lung parenchyma. This complication is particularly prevalent in patients suffering from chronic congestive cardiac failure. The usual finding in such cases is obstruction of a segmental or smaller artery with infarction of the parenchyma supplied by it. The haemorrhage itself is usually slight ...
