Inverted nipple is a relatively common aesthetic problem presenting to a plastic surgeon. Along with the functional problems; recurrent inflammation/infection and an inability to nurse, most patients seek intervention because of the abnormal appearance. Many different surgical techniques have been described, suggesting that no one technique is universally successful. Most techniques employ, either individually or in combination, methods to tighten the nipple base or the use of areolar dermal flaps to support the nipple...

Pulmonary sequestration (PS) is a rare disease where non-functioning lung tissue is separated from the normal bronchopulmonary tree and vasularized by an aberrant systemic artery. The origin of PS is not fully understood. Here we describe two unique cases of PS that support the hypothesis that PS is a congenital malformation rather than an acquired one. These are also the first Icelandic cases of PS reported.

BACKGROUND: Our understanding of the process leading to hypertension is allowing us to adopt principles of therapy that may be more beneficial for patients. OBJECTIVE: To review the physiology, vasular biology, and mechanisms of hypertension. SUMMARY: Hypertension, particularly in high-risk patients, is a result of loss of balance and the absence of the ability to vasodilate normally. The interaction between the endothelial cell and the smooth muscle cell is very important in this process...

Mesenteric trauma, i.e., injuries located in the bowel or organs supplied by the superior mesenteric artery, can be life-threatening. The incidence of these lesions is low. Most occur as result of blunt and penetrating abdominal trauma due mainly to gunshot wounds or road accidents. Management of these serious injuries can be challenging in the military field hospitals. The major problem in austere environment is the unavailabiity of computerized axial and other tools gene rally used for diagnosis. As an alternative to tomography diagnostic peritoneal lavage can be used with a high sensitivity for the detection of mesenteric trauma...

The Authors present a case of Splenic Hamartoma. This is a rare unique complex vascular lesion of the spleen. This is also a recently reinterpreted lesion with some persistent confusion regarding its definition, histogenesis and classification. The patient is a young woman who following a check up with a raised erythrocyte sedimentation rate underwent abdominal sonography demonstrating an incidental slightly hypoechoic nodular splenic lesion. The pathologic study of the splenectomy specimen showed a large (10 cm) sharply demarcated mass...

REVIEW
P Cogliati
Among the advantages of hemodiafiltration (HDF) cardiovascular stability seems the most popular. For several years the theory was that fluid infusion at a lower temperature induced similar effects to 'cool dialysis'. Due to the studies of Maggiore in 1982, we know that hemodialytic treatment per se induces in the majority of patients a rise in body temperature, on average 1.5-2 degrees C; the reasons for this phenomenon are unclear, even if theories developed in different trials take the following deputed to body cooling into account; an increase of the catabolism, linked to the bioincompatibility of the materials or to pyrogenic and cytokine-inducing substances, or a reduction in thermal scattering by the vasoconstriction of vasular districts such as skin and muscles...

The present studies suggest that polymorphonuclear leukocytes (PMN's) are essential for the development of cardiovascular lesions in serum sickness. In the absence of PMN's, necrotic vascular lesions were never seen and endothelial proliferation in arteries was inhibited. Zones of fibrinoid deposits did not occur. By contrast, at least two-thirds of the control animals exhibited endothelial proliferation, and half had necrosis of arterial walls, usually with fibrinoid deposits. In arterial lesions that involved the intima and media, the internal elastic lamina was disrupted...

Tissue factor (TF), the major initiator of blood coagulation, serves as a regulator of angiogenesis, tumor growth and metastasis. In several models, TF expression mediates upregulation of the proangiogenic vasular endothelial growth factor (VEGF) that can directly act on endothelial cells to promote vessel formation. This occurs through ligand binding, activation of signaling cascades, signal transduction and alteration of growth factor expression and is mediated by both, coagulation-dependent and -independent pathways...

The clinical features of preeclampsia have been traditionally ascribed to a generalized vascular endothelial cell dysfunction. The present study investigates the effect of sera from preeclamptic women and normal pregnancy on the metabolism of intracellular Ca(2+) concentration ([Ca(2+)](i)) in normal cultured vascular smooth muscle cells (VSMC). Sera were obtained from normotensive pregnant women (NTP) (n = 17), preeclamptic women (PE) (n = 15), pregnant women with chronic (essential) hypertension (pregnant EHT) (n = 8), non-pregnant women with essential hypertension (non-pregnant EHT) (n = 12), and age-matched non-pregnant normotensive women (NNP) (n = 18)...

The experience on management of abnormal blood vessels in 128 cases of donor kidney during the tailoring operation was reported. The various techniques used for different types of abnormal arteries and veins, and the critical points which should be paid attention to have been discussed. It was concluded that the multiple renal arteries should be treated in a single renal artery and anastomosed with internal iliac artery or/and external iliac artery. The appropriate management given to abnormal renal blood vessels during the tailoring operation may shorten the warm ishemia time, ensure the renal blood supply, reduce the renal vasular complication, and promote the recovery of renal function...

BACKGROUND: Color-coded duplex sonography is being increasingly used in the head and neck as another method of diagnosis of, for example, stenosis of arteries or veins or of hemangioma. Moreover, it is of greatest interest in having the ability to differentiate benign from malignant tumors. Since the underlying type of tumor is directly responsible for the (operative) treatment recommended we have investigated histologically proven benign and malignant parotid tumors. PATIENTS: Thirty-six patients (20 women, 16 men, ages 32-66 years) with parotid tumors of unknown histology were examined by means of ultrasound and color-coded duplex sonography...

In 43 test animals the state of the blood bed in the retrobulbar formations and the eyeball vasular tunic has been studied under venous congestion produced by ligation of the anterior vena cava (in dogs) and both external jugular veins (in rabbits). A complex of histological, histotopographic, morphometric and variation-statistical techniques has been used. The results obtained demonstrate that disturbances in the venous outflow in the anterior vena cava system produce certain responses in all parts of the retrotubular adipose tissue, of the eyeball muscles, of the optic nerve tunics, of the vascular tunic...
