The primary malignant melanoma arising in the leptomeninges of the central nervous system is extremely rare. We report a case of malignant melanoma, apparently thought to be originated from leptomeninges, with diffuse neoplastic process widely spreaded over the leptomeninges of 42 years old man, who had suffered severe headache, nausea and left hemiparesis. This patient is free of the symptoms for six months after operation. The literature on this subject is briefly reviewed.

5.Mechanisms of Increase in Renal Blood Flow During Partial Ureteral Obstruction in Dogs.

Although tubuloglomerular feedback (TGF) is involved in ureteral obstruction-induced increase in renal blood flow (RBF), its contribution to RBF is not well established due to the concommitant increases in prostaglandin (PG) and renal interstitial fluid pressure (Pisf), both of which affect RBF one way or the other. Since Pisf and TGF are closely affected by renal hemodynamics, RBF will respond differently to increases in ureteral pressure depending on renal hemodynamic conditions. Therefore, the purpose of the present study was to investigate how the changes in renal hemodynamics affect the response of RBF to increases in ureteral pressure. The effect of PG on RBF was assessed by comparing the effects obtained before and after indomethacin, a cyclooxygenase inhibitor. Six anesthetized dogs were prepared with flow probes and inflatable silastic occluder around the renal artery, the ureteral catheter with its free end attached to a water reservoir, and the arterial and venous catheters. RBFs were obtained at ureteral pressures of 0, 15, and 40cmH2O during the maintenance of the renal artery pressure (RAP) at the level of systemic arterial pressure, 10mmHg above and below the lower autoregulatory limit of RBF (65+/-4 mmHg) both before and after indomethacin administration (10mg/kg). In response to the ureteral pressure of 40cmH2O, RBF increased from 172+/-6 to 185+/-10ml/min when RAP's were equal to systemic arterial pressure and decreased from 162+/-10 to 120+/-9 ml/min when RAP's were 55+/-4mmHg. Indomethacin pretreatment, depending on the level of RAP either prevented an increase or augmented a decrease in RBF in response to ureteral pressure elevation. This suggests that RAP-dependent changes in susceptibility of the renal venous system to compression by increased Pisf is the main mechanism by which the changes in renal perfusion pressure modulate the response of RBF to ureteral pressure elevation.

6.Acute Pulmonary Hypertension and Hypoxemia Following Indwelling Swan-Ganz Catheter during Coronary Artery Bypass Graft: A case report.

Balloon-tipped, flow-directed (Swan-Ganz) catheters are used commonly for monitoring of cardiac function in patients undergoing cardiac surgical procedures. We report a case of pulmonary hypertension with hypoxemia which may be caused by incorrect positioning of pulmonary artery catheter (PAC) during CABG. Pulmonary arterial pressure (PAP) of 70/40 mmHg which was nearly high as systemic pressure was measured when we tried to wean patient from cardiopulmonary bypass. But, TEE (transesophageal echocardiography) showed nonspecific finding. PAP decreased soon and maintained about 33/16 mmHg for a few minutes. But, the PAP elevated high to 70/40 mmHg again and the arteral oxygen tension (PaO2) decreased to 61.2 mmHg. When we withdrew the PAC to the depth of 35 cm, the PAP and systolic pressure returned to normal range and PaO2 elevaed to 320 mmHg. End tidal CO2 was elevated from 30 mmHg to 35 mmHg.

8.The evaluation of the cervical lymph node metastases using computed tomography in the head and neck cancer

Journal of the Korean Radiological Society 1985;21(3):392-397
Fity-four patients with head and neck cancers were prospectively examined with the CT to determine its valuein staging cervical lymph nodes metastases and to compare with the clinical staging. The CT staging agreed withthe clinical staging in 61%(33/54), upgraded the clinical staging in 22%(12/54) and downgraded in 17%(9/54). Thepost-surgical confirmation was made in only 11 patients, The possible causes of disagreement between the CT andthe clinical staging, and the diagnostic value of the CT in the evaluation of the cervical nodes metastases werediscussed.
