Lumbar disc herniation (LDH) associated with a contralateral neurological deficit is sometimes encountered by surgeons. Compression against the opposite pedicle in case of a large discal herniation and prominent stenotic changes of contralateral side are held responsible for contralateral symptoms and findings. In this study, we report a case of LDH associated with a painless contralateral neurological deficit. Prominent venous engorgement and congestion at the contralateral side of discal herniation were detected during the operation. It's treatment with bipolar coagulation and significant improvement was seen after the operation.

Cerebral developmental venous anomaly (DVA) is generally benign. However, we have experienced two cases of DVA causing symptoms. In the first case, the patient demonstrated DVA with venous infarction. DVA was visualized in the arterial phase using digital subtraction angiography (DSA), and was diagnosed as arterialized DVA. The second case presented as transient right homonymous hemianopia. DSA revealed venous congestion; the transient aggravation of venous congestion may have caused the symptom. DSA is useful for diagnosing the pathomechanism of symptomatic DVAs.

Radiational injury to ultra-violet rays has brought to acute flash-eye of occupational type in four patients who didnt used the protective eye-wear; Case 1, a medical physician. 29 yr old male, was occurred the symptoms after exposure of about 3 hrs to ultra-violet lamp in the laboratory. Case 2, a trainee of welding, 19 yr old male, was occurred from electric welding. Cases 3 and 4, all electricians of 38 and 26 yrs old males, were occurred typical photophthalmia from the spark of electric arc. They all revealed prominent hyperemia especially in exposed area of the bulbar conjunctiva.

The use of medicinal leech(Hirudo medicinalis) has been increased during the past years and is a very common procedure for treatment of venous congestion in flaps and replanted part in plastic surgery. One of the main complication in using leeches is infection. We used the medicinal leeches in venous congestion after total ear reconstruction(8 cases) and replanted finger(1 case). A bacteriologic study of the leeches is undertaken before applying it to the patient and an antibiotic susceptibility test was also performed. In 6 patients. 6 pathogenic organisms were identified, and in 2 cases 2 different organisms were identified simultaneously.

The diagnosis of existence of conjunctivitis with its cardinal symptoms of hyperemia and disch arge is easy, but the differential diagnosis of the types of inflanimation frequently presents problems of considerable difficulty. Their solution depends on a careful and systemic clinical survey, reinforced by bacteriological and cytological investigation. So, the diagnosis of conjunctivitis is based on the followings: 1. History and clinical examination. 2. Gram and Wright gtains of conjunctival discharge and scrapings. 3. Culture of conjunctival discharge and scrapings. 4. Biopsy of the conjunctiva.

In 2009 Paolo Zamboni et al. implicated that chronic cerebral venous congestion lead to the development of multiple sclerosis. In this review, we examined the role of chronic cerbrospinal venous insufficiency in multiple sclerosis and the proposed therapy entailing venous angioplasty and stenting of extracranial veins with available evidence to date.

BACKGROUND AND OBJECTIVES: The achievement of maximal vasodilatation is mandatory for obtaining valid measurements of the coronary flow reserve (CFR) and the fractional flow reserve (FFR). Recent studies have indicated that an incremental dose or a high dose of adenosine is necessary to achieve maximal hyperemia. We performed this study to examine the response of the physiologic parameters to different doses and to different methods of administration of adenosine in Koreans. SUBJECTS AND METHODS: CFR: The CFR was measured in 25 consecutive patients with angiographically normal coronary arteries by using a Doppler wire. Three different doses (9, 18 and 36 microgram in the left coronary artery (LCA), and 6, 12 and 24 microgram in the right coronary artery (RCA)) of adenosine were used. FFR: In a phase I study, 102 consecutive patients with 188 intermediate lesions (160 LCA and 28 RCA lesions) underwent FFR measurements with using a pressure wire. Three different bolus doses (20, 40 and 80 microgram) were administered in an incremental fashion. In a phase II study, the hyperemic efficacy of 3 different doses of intracoronary (IC) infusion (180, 240 and 300 microgram/min) and of 3 methods of administration (IC infusion, intravenous infusion and IC bolus) were compared. RESULTS: CFR: The higher 2nd dose of adenosine had a tendency to achieve a higher CFR than the lower 1st dose. But when we increased the adenosine to more than 20 microgram (LCA 36 and RCA 24 microgram), there was a tendency towards obtaining a lower CFR than that obtained after the 2nd dose of adenosine (LCA: 2.78+/-0.71 vs. 2.66+/-0.60, p=0.055, RCA: 3.19+/-0.88 vs. 3.04+/-0.80, p=0.86). FFR: Phase I: The dose of adenosine that achieved maximal hyperemia was 51+/-16 microgram in the LCA and 35+/-20 microgram in the RCA. In 73 (46%) of the LCA lesions and 12 (42%) of the RCA lesions, a further reduction of the FFR occurred when a higher dose of adenosine was used (LCA>40 ug, RCA>20 microgram). Phase II: The FFR obtained after an IC bolus injection (0.83+/-0.06) was significantly higher than obtained with an IV infusion (0.79+/-0.07) and an IC (0.78+/-0.09) infusion (p<0.01). However, no difference in the FFR was observed for the IC and IV infusions. CONCLUSION: This study suggests that more than 20 microgram adenosine does not have an additive effect on measuring the CFR. Adenosine 40 microgram for the LAD and 20 microgram for the RCA seems to be optimal as a intracoronary bolus injection for measuring the FFR in most cases. However, for the patients with borderline FFR, a higher bolus adenosine dose or an adenosine continuous infusion may be necessary.

BACKGROUND AND OBJECTIVES: The purposes of this study are 1) to investigate the relationship between resting baseline Pd/Pa, determined by the ratio of the pressures proximal (Pa) and distal (Pd) to the target lesion before, inducing hyperemia and fractional flow reserve (FFR) and 2) to identify a resting baseline Pd/Pa range that might reliably preclude the need for hyperemic induction. SUBJECTS AND METHODS: A total of 622 pressure wire data sets obtained from intermediate stenotic lesions were analyzed. RESULTS: There was a good linear relationship between resting baseline Pd/Pa and FFR (r=0.746, p<0.001). Receiver-operating characteristic curves of the resting baseline Pd/Pa with FFR < or =0.80 as the reference variable showed an area under the curve of 0.89 (95% confidence intervals 0.863-0.914, p<0.001) with a diagnostic accuracy of 82.3% when the resting baseline Pd/Pa was < or =0.92. These results showed that certain cutoff values can reliably predict FFR, whether positive or negative. The resting baseline Pd/Pa >0.95 (n=257, 41.3%) had a negative predictive value (NPV) of 98.1% and a sensitivity of 97.3%. the resting baseline Pd/Pa < or =0.88 (n=65, 10.5%) had a positive predictive value (PPV) of 96.2% and a specificity of 99.8%. These were consistent regardless of coronary vessel, lesion location, lesion length, or degree of stenosis. CONCLUSION: In intermediate lesions, the resting baseline Pd/Pa was linearly related to FFR. A certain range of the resting baseline Pd/Pa values had an excellent NPV with high sensitivity or excellent PPV with high specificity for determining the lesion significance.
