As a clinical tool to evaluate autonomic dysfunction, "Valsalva ratio" was measured in 36 Parkinson's disease patients (15 men, 21 women) and 10 control subjects (4 men, 6 women). In this study, the Valsalva ratio was defined as the ratio of peak to nadir heart rate during Valsalva maneuver, namely voluntary and transient breathholding in maximal inspiration state with subsequent release by the subject. EKG was monitored throughout the whole process to observe the moment to moment change of heart rate. The subject group with Parkinson's disease was subdivided by clinical variables including sex, are, Hoehn and Yahr clinical stage, duration of symptoms, and duration of therapy with L-dopa containing drugs. The Valsalva ratio of the subject group as a whole was less than that of the control group (P<0.05). But the differences of Valsalva ratio between the subgroups graded by above clinical variables of Parkinson's disease were not statistically significant. The clinical applicability of "Valsalva ratio" measurement described in this study was discussed.

PURPOSE: Orbital varices, which can lead to proptosis or globe displacement, are caused by Valsalva's maneuver or bending forward. Most of the orbital varices are treated conservatively, but surgical treatment is necessary for severe cosmetic or functional problems. We report a case of orbital organizing hematoma accompanied by an orbital varix which was successfully removed surgically without complications such as intraoperative bleeding. CASE SUMMARY: A 78-year-old female presented with the complaint of 4 mm proptosis and hyperglobus of left eye. Orbit magnetic resonance imaging (MRI) showed a well demarcated extraconal mass in the inferior orbit which appeared to be an orbital varix. Initially, we decided to monitor the patient without surgery because proptosis was reduced to 1 mm within a week. However, after 5 months, the symptoms suddenly worsened, specifically, 4 mm of proptosis with severe hyperglobus and pain. MRI showed a 29.7 x 21.2 x 23.7 mm mass compressing the globe upward. Six weeks of conservative care did not improve the symptoms and we eventually performed an anterior orbitotomy through the inferior conjunctiva. There was a minor bleeding during the surgery. Based on the histological test, the mass was determined to be an organizing hematoma covered by a membrane. At 8 months postoperatively, symptoms had not recurred. CONCLUSIONS: Orbital varices are usually treated conservatively since its surgical removal is known to have risks. Nonetheless, if an MRI shows an orbital organizing hematoma, it can be surgically debulked successfully without complications when a chronic hemorrhage from orbital varix causes serious proptosis and globe deviation.

PURPOSE: Retrograde flow is the main criterion for the diagnosis of varicocele, and the Duplex Doppler ultrasonographic values for retrograde flows are poorly defined. The purpose of this study is to assess a relationship between the palpated varicocele and pampiniform plexus diameter and the retrograde flow that was investigated with performing Duplex Doppler ultrasonography (DDU). MATERIALS AND METHODS: Physical examinations and DDU were performed to assess varicoceles in forty patients with left-sided varicocele and also in eight men who were without varicocele on their physical examination. During both normal respiration and the Valsalva's maneuver, the maximum diameters of the pampiniform plexus and the presence of the retrograde flow were measured by DDU. RESULTS: The highest mean venous diameter in the patients with clinical grade III varicocele was 2.7mm (2.4-3.6), and this was significantly higher than that in the patients with grade I (1.9mm) or with grade II varicocele (2.1mm) (p<0.05). While the difference of diameters between grade I and grade II was not significant, venous reflux was found in all degrees of the varicocele veins. Venous reflux during the Valsalva maneuver (type II flow pattern) was detected on the right side in one (8%) of 13 patients with grade II varicocele, and in three (21%) of 14 patients with grade III varicocele. The type III flow patterns, indicating augmenting of the reflux with an intra-abdominal pressure increase, were 46.1%, 69.2% and 100% for grade I, II and III, respectively. No venous reflux was found in the control group. CONCLUSIONS: The presence of retrograde flow may provide a more reliable indicator than does the spermatic vein diameter for the diagnosis of varicocele. When the palpability of the pampiniform plexus is questionable, Duplex Doppler ultrasound is indicated.

Purpura is discoloration of the skin and mucous membranes due to extravasation of red blood cells and may be due to a variety of factors, but it is sometimes difficult to identify the exact cause. Some forms of purpura can frighten the patient and puzzle the physician. Mask phenomenon is an unusual purpura of the relatively loose tissues of the face and neck occuring after prolonged coughing, vigorous vomiting, valsalva's maneuver, parturition, or any other exertion that raises intrathoracic or abdominal pressure. This occurs with acute onset and fades within twenty-four to seventy-two hours spontaneously. A work-up for a coagulation or platelet defect is usually not required. We herein describe five cases of mask phenomenon(unusual facial purpura).

The majority of melanotic neoplasms of central nervous system(CNS) are metastatic in origin and rarely a primary CNS melanomas, and are usually histologically and clinically malignant in nature. The meningeal melanocytomas are benign, primary melanotic neoplasm and are less common than primary CNS melanoma. They usually present in early adult and have a characteristic appearance in light and electron microscope. A 42-year-old male is presented with pain on the neck and suboccipital region which was worse with flexion and Valsalva's maneuver. MRI revealed homogenous high signal intensity on the T 1 weighted image and low signal intensity on the T 2 weighted image. At operation, the tumor was well circumscribed, pigmented lesion and was attached to dura and cord. Microscopically, the tumor was composed of spindled and epithelioid cells with often prominent nucleoli, without evidence of mitosis and necrosis.

PURPOSE: To evaluate the hemodynamic status of varicocele, 99m Tc-RBC venography was performed in 29 varicocele patients and 10 normal controls from January to July 1996. MATERIALS AND METHODS: The mean age of varicocele patients was 23 years old and of normal controls was 27 years old. Among 29 varicocele patients, 26 had varicocele in left side and 3 had in both side. In unilateral varicocele group. 2 cases had grade I, 8 cases had grade II and 16 cases had grade III varicocele. In bilateral varicocele group, all had grade III in le% side and grade II varicocele in right side. RESULTS: The mean+/-SD of left to right radionuclide uptake ratio in pampiniform plexus during resting and Valsalva maneuver state was 1.01 +/-0.04:1 and 1.05+/-0.05:1 in normal control, 1.05+/-0.02:1 and 1.10:1 in varicocle grade I, 1.21+/-0.19:1 and 1.21 +/-0.12:1 in varicocele glade II, 1.60+/-0.63:1 and 1.27+/-0.18:1 in varicocele grade III, 1 18+/-0.06:1 and 1.26 in bilateral varicocele. As varicocele grade be higher, the mean left to right radionuclide uptake ratio be larger during resting and Valsalva maneuver state. CONCLUSIONS: 99mTc-RBC venography can quantify the hemodynamic state of varicocele so we suggest that it is useful as a method of diagnosis and follow up in varicocele patient.

PURPOSE: To assess the ability of scrotal Doppler ultrasonography to confirm the diagnosis of clinical varicoceles and detect subclinical varicoceles. MATERIALS AND METHOD: Sixty patients with clinically evident varicocele were examined by scrotal doppler ultrasonography(gray scale: 60 patients, spectral Doppler: 35 patients, color Doppler: 22 patients). A control group of 21 patients with no suspected scrotal pathology also were studied. The age range of the varicocele group was 12-49 years. The normal group consisted of 21 subjects aged 19-23 years. Ultrasonographic measurement of scrotal vein diameter of patients before and during Valsalva maneuver, and scrotal vein blood flow reversal with Valsalva maneuver was compared with the findings of varicocele by physical examination. RESULTS: Significant differences were found in scrotal vein diameter before and during Valsalva maneuver between normal and varicocele testicular units. Cut-off points were selected in an arbitrary fashion on the basis of scattergram. Using this cut-off points and blood flow reversal, we found that 12(23%) of 53 patients with a clinically palpable left unilateral varicocele had an ultrasonographically positive subclinical right varicocele. 8(38%) of 21 patients without a clinical varicocele had a positive scrotal ultrasound. CONCLUSIONS: We suggest that scrotal doppler ultrasonography is a reliable means of confirming the clinical varicocele and screening the subclinical varicoceles.

PURPOSE: The aim of this study is to assess effects of testicular volume difference and retrograde venous flow of pampiniform plexus measured by Duplex Doppler Ultrasonograpy (DDU) in patients with adolescent varicocele. MATERIALS AND METHODS: Physical examinations and DDU were performed to assess varicocele in fifty five patients with left sided adolescent varicocele. During both normal respiration and the Valsalva's maneuver, the maximum venous diameter (MVD), maximal velocity of reflux and the peak retrograde flow volume (RFV) was measured by DDU. The percentage testicular volume difference (%) between the right and left testicle was calculated as (right testicular volume-left testicular volume)x100/right testicular volume and divided into 3 group; below 10%, 10~20%, >20%. Grade of varicocele, MVD and peak RFV were analyzed as possible determinants of testicular hypotrophy in adolescent varicocele. RESULTS: A total of 55 patients (mean age 17.8 years, range 12 to 20) were included in this study. Of these, physical examination reviewed that 7 (12.7%), 18 (32.7%), 30 (54.6%) patients had grade I, II or III varicoceles on the left side respectively. The mean MVD was significantly higher according to grade of varicocele. The mean maximal velocity of reflux was significantly higher in the patients grade II and III than grade I, but was not significant between grade II and III. The mean peak RFV was significantly higher according to grade of varicocele. RFV was the only significant parameter of predictive value for percentage testicular volume difference. CONCLUSIONS: Patients with peak RFV >35ml minutes showed significant reduction of testicular volume. Measurement of RFV is recommended as predictive tools for assessing the percentage testicular volume difference in patients with adolescent varicocele.

Incidences of blowout fractures have increased due to rapid industrialization and rise in violent crimes. However, there have been few studies on the proper follow-up guidelines or protocol after reduction of the orbital wall for patients working in a high atmospheric pressure environment. We have experienced a pilot with an orbital medial wall fracture who underwent reduction through an endoscopic approach. The patient underwent the Valsalva maneuver and scan of paranasal sinuses 8 weeks after reduction. Emphysema did not occur in the orbit even after the Valsalva maneuver and he was able to return to his workplace without any complications. We report this case with a brief review of the literature.
