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.

A 48-year-old man presented with acute right flank pain. A computed tomography scan revealed right renal infarction. Because he had no thrombosis in the renal vessels and no clear embolic source, a further examination was performed to find the cause of the renal infarction. On transesophageal echocardiography, a right-to-left shunt during the Valsalva maneuver established a diagnosis of patent foramen ovale. This is a case of paradoxical embolism through a PFO leading to renal infarction.

PURPOSE: The study purpose was to evaluate the clinical and ultrasound characteristics of women with urinary stress incontinence (USI) with or without genital prolapse (GP). MATERIALS AND METHODS: A total of 268 patients who underwent ultrasound perineal evaluation were divided into two groups: isolated USI (n=132) and USIGP (n=136) with USI/GP stage I/II. The latter group was additionally divided into two subgroups: USIGP(A) (n=78) with USI/GP stage I and USIGP(B) (n=58) with USI/GP stage II. RESULTS: Point Aa (pelvic organ prolapse quantification system), which is the projection of the bladder neck (BN) on the anterior vaginal wall, was situated higher in the rest position (RP) but moved lower during a Valsalva maneuver (VM) in the USI group than in the USIGP group (p<0.05). The ultrasound parameters alpha-angle and the distance Sy-BN (symphisis-bladder neck) decreased, whereas distance H increased, in the USIGP group during VM. The ultrasound parameters that gave the best insight into the range of BN movements were as follows: distance R-->V and angle of rotation (rho), which were significantly higher in the USI group than in the USIGP group during VM. CONCLUSIONS: According to the clinical and ultrasound findings, we can conclude that the BN is situated higher during the RP but moved lower during a VM in patients with isolated USI compared with those with concomitant USI/GP, which could be explained by the cystocele-immobilizing effect on the BN during the VM in the latter group but also by the deteriorated pubo-urethral ligaments in the former group.

The clinical symptom complex characterized by syncopal attacks and sudden death in patients with electrocardiographic anomalies, especially a prolonged Q-T interval is known as the Romano-Ward syndrome. When a similar symptom complex is accompanied by congenital deafness, it is called Jervell and Lange-Nieisen syndrome. This study was undertaken to investigate the investigate the incidence of the latter syndrome in the Seoul area. A total of 1,013 children with congenital deafness who attend schools for the deaf were studied by analyzing their electrocardiograms. A corrected Q-T interval of> or =0.44 seconds was defined as a prolonged Q-T interval. The overall incidence of long Q-T syndrome observed in the deaf in the Seoul area was 0.49% as compared to 0.25% reported from elsewhere in the world. The mean age of patients with long Q-T syndrome was 11.3+/-5.9 years and the first syncopal attacks was 4.6+/-1.1 per patient. A valsalva maneuver and exercise tests in the test group were associated with significant changes in T wave configuration and prolonged Q-T intervals while similar changes were not observed in the control group. A larger survey is needed to derive more statistically significant conclusions.

Studies on the prevalence of varicocele and the relation of varicocele to scrotal temperature and testicular volume were performed on 986 healthy Korean boys 6 to 15 years of age for 5 months from the May, 1988 to September, 1988. We examined the subjects in standing position with Valsalva maneuver for detecting varicocele and classified the varicocele as grade I, grade II, or grade III according to the system proposed by Dubin and Amelar in 1970. Scrotal temperatures were measured in standing position by contact scrotal thermography using Varicoscreen, a flexible screen covered with thermosensitive liquid crystals reflecting color from brown (at 31.8 degrees C) to blue (at 34.5 degrees C). Testicular volume was measured by indirect method using series of graduated plastic models (Prade orchidometer). Following results were obtained. The overall prevalence rate of varicocele aged 6 to 15 years was 8.8%. No case of varicocele was encountered in 303 boys aged 6 to 8 years, while the incidence in the 683 subjects 9 to 15 years was 12.8% with an increase from 2.9% in 9-year-olds to 18.8% in 14-year-olds. Among 87 varicocele subjects, varicocele accounted for 75.9% in the left side, 5.7% in the right and 18.4% in both sides. And of 103 varicocele testes 51.5% were classified as grade I, 29.1 % as grade II and 19.4% as grade III. The scrotal temperature exceeded 31.8 degrees C in their contralateral normal testes. Varicocele increased scrotal temperatures not only in the affected side, but also in the other side. Scrotal temperature in varicocele testes was revealed significantly higher than that in normal (p<0.01). The degree Of varicocele bears relation to scrotal temperatures (p<0.01). In healthy Korean boys in 6-year-olds, the mean testicular volume was 1.1+/-0.4 ml. The testicular growth rapidly increased in 11-year-olds and in 15 years of age testis was 14 times larger than that of 6-year-olds. There was no volume differential between both testes in normal subjects. In the subjects with unilateral left varicocele, the testicular volume was decreased in both sides than in the normal subjects. Ipsilateral and contralateral testicular volume was most prominently decreased in grade III varicocele.

Internal jugular phlebectasia (IJP) is a fusiform dilatation of the internal jugular vein (IJV), usually presented as a neck mass in children. Accurate diagnosis from carefully directed history, physical examination, and radiological study could result in lifesaving therapy. We performed our study to suggest possible clinical diagnostic criteria for IJP in Korean children. We reviewed three cases of IJP (patients group) and compared the diameter of the internal jugular phlebectasias with diameters of IJVs in ten normal children (control group) using ultrasonography (USG). There were no significant differences in the range of diameters in the resting state between the two groups. The diameters on the right side, compared with those on the left side, showed no statistical significance (p < 0.05). Te range of expanding diameter and average expanding ratios (resting state to Valsalva maneuver X 100%) showed a statistical difference between the two groups (p < 0.05).

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.

PURPOSE: The association of varicoceles and subfertility has been well documented. Although varicoceles remain the most common surgically correctable cause of male infertility the subjective diagnosis of varicocele, especially the small ones remains a challenge. MATERIALS AND METHODS: We evaluated 40 young men (16 volunteers, 24 varicocele patients) with scrotal blood pool scan using 99mTc RBC. RESULTS: Complete correlation between physical findings and the scrotal scan was found. The postoperative scans of 12 patients with surgically corrected high grade varicoceles demonstrated symmetrical photon accumulation in the scrotum. The technique which most accurately correlated the clinical grade was the varicocele index using total count at Valsalva maneuver. CONCLUSIONS: We believe that the 99mTc RBC scrotal scan with technical refinement is a useful procedure in the objective diagnosis and followup of varicoceles.

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.

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.
