A Case of Kaposi's Sarcoma Following Treatment of Membranoproliferative Glomerulonephritis and a Review of the Literature

Kaposi's sarcoma (KS) is an unusual tumor principally affecting the skin of the lower extremities. Although the association between KS and renal transplant has been well documented, there are a few KS cases in the literature associated with membranoproliferative glomerulonephritis or other glomerular diseases. This report presents a patient with membranoproliferative glomerulonephritis (MPGN) who developed KS following treatment with long-term medium dose glucocorticoid and short-term additional immunosuppressives. The KS cases associated with glomerulonephritis are also reviewed. KS is a rare complication in glomerular diseases that may (or may not) be related to immunosuppression. Hence, immunosuppression treatment should be carefully planned in glomerulonephritis treatment and avoided if they are not essentially necessary.     

Sensorial donor site morbidity after saphenous neurocutaneous flap

Neurocutaneous flaps based on the arterial network around the superficial sensory nerves are popular in soft tissue coverage of the lower extremities, and are usually preferred in reconstruction of the lower leg and foot. Although sacrifice of sensory cutaneous nerves is mentioned as one of their major disadvantages to our knowledge the morbidity in the foot and at the donor site has not been properly investigated. We investigated sensorial morbidity in the foot and at the donor site caused by raising a saphenous neurocutaneous flap in 14 patients by using static two-point discrimination test, Semmes-Weinstein monofilament test, vibration test, and by measuring somatosensory evoked potentials in the twelfth postoperative month. Our results suggest that sensory recovery is good and protective sensation is gained in most patients.     

Effect of plasma NO<Subscript>x</Subscript> values on cardiac function in obese hypertensive and normotensive pediatric patients

Background

Hypertension (HT) is a major comorbidity of obesity that is associated with an increased risk of cardiovascular disease and higher mortality. The aim of our study was to evaluate cardiac function in obese hypertensive (OHT) and obese normotensive (ONT) pediatric patients and determine the effects of plasma nitric oxide (NO_x) values on cardiac function, while demonstrating the role of plasma NO_x in HT in obese pediatric patients.

Methods

The study population consisted of 62 patients (27 boys, 35 girls), aged 13–18 years and 21 age-matched healthy controls. All subjects enrolled in the study underwent echocardiography (Echo) evaluation and ambulatory blood pressure monitoring for HT. Plasma NO_x and biochemical values were studied in both patient groups separately.

Results

Plasma NO_x levels were found to be lower in the OHT group than in the ONT and control groups (p?<?0.001) and to be negatively correlated with left ventricular mass index values (p?<?0.05). Both the OHT and ONT groups had concentric hypertrophy of the heart.

Conclusions

Plasma NO_x plays an essential role in obesity-induced HT. Concentric hypertrophy of the left ventricle was found in both the OHT and ONT groups, indicating structural deformation of the heart.
