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.

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 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.

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.

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.

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.

BACKGROUNG AND OBJECTIVES: The aim of this study was to analyze the influence of changes in ventricular preload and afterload, atrial and ventricular pacing on the coronary flow reserve (CFR). METHOD: Five open chest anesthetized dogs were studied in five sequential stages:baseline, saline solution volume loading (293.8+/-29.2 ml for 10 min), atrial and ventricular pacing (120, 140, and 160 bpm), and aortic clamp. Coronary blood flow (CBF) was measured with electro-magnetic flowmeter. CFR was defined as the ratio of hyperemic CBF (hCBF) to resting CBF (rCBF). Hyperemia was induced by IV adenosine infusion (1 mg/kg/min). RESULTS: 1)After volume loading wtih saline solution, CFR significantly decreased (p<0.05) because rCBF was increased while hCBF remained unchanged. 2)Atrial pacing produced increase in rCBF but did not change hCBF. Consequently CFR singificantly reduced when heart rate (HR) increased from sinus rhythm to 120, 140, and 160 bpm (p<0.01). 3)Ventricular pacing produced decrease in hCBF but did not change rCBF. Consequently CFR significantly reduced as HR increased from sinus rhythm to 120 (p<0.05) , 140 (p<0.01), and 160 (p<0.01) bpm. 4)After aortic clamp, CFR significantly decreased (p<0.01) because rCBF increased while hCBF remained unchanged. CONCLUSION: We found that CFR is dependent on the changes in volume loading, HR, and ventricular afterload that may commonly occur in clinical situations.

BACKGROUND AND OBJECTIVE: Fractional flow reserve (FFR) has emerged as an easily obtainable, and accurate, lesion-specific parameters for the physiological evaluation of coronary artery stenosis. However, the effects of the lesion length and eccentricity on the FFR remain unclear. Therefore, the relationship between the lesion length and eccentricity to the FFR, and the lesion length to the degree of stenosis were studied to see if there was any significant influence on the trans-stenotic pressure gradients and the FFR. SUBJECTS AND METHODS: Intravascular ultrasound (IVUS) was performed and the FFR measured in 19 lesions, ranging from 80 to 90% in area stenosis (AST), using a pressure wire. The eccentric index at the most stenotic site, and the length of the coronary stenosis lesion, above 50 and 70% of the AST, at the most stenotic site were obtained using IVUS. The FFR was defined by the ratio of distal mean coronary pressure (Pd) to that of the aortic mean pressure (Pa) under hyperemia. RESULTS: The FFR showed no correlation with the eccentricity or the length of the stenosis lesions when they were more than 50% of the AST (p>0.05). However, the FFR showed a significant correlation with the length of the most stenotic lesions (r=-0.79, p<0.001) and the lesions with an AST of more than 70% (r=-0.47, p<0.05). The hyperemic pressure gradient across the lesion showed a significant correlation with the length of the lesion, but only to those with the most severe portion of stenosis (r=0.64, p=0.003). CONCLUSION: In the functional evaluation of coronary stenosis, the length of the most stenotic lesions, as well as the cross sectional area and minimal lumen area at the most stenotic lesion, should be considered, as this study has shown that the length of the most severe stenotic lesion could influence the FFR and trans-stenotic pressure gradients.
