Typical vasculitic neuropathy commonly manifests as a subacute multiple mononeuropathy, symmetrical or asymmetrical sensori-motor polyneuropathy. Various clinical presentations of peripheral neuropathy may confuse the diagnostic approach sometimes. A 76-year old man presented progressive areflexic ascending paralysis. gait ataxia, severe vibration and position sense impairment for 1 month. We initially considered as subacute demyelinating polyneuropathy. Electrophysiologic studies showed mainly axonopathy with some evidence of demyelination. We performed sural nerve biopsy and diagnosed as vasculitic neuropathy. No laboratory data or clinical findings favored systemic vasculitic involvement. So we concluded vasculitis confined to the peripheral nerves. Vasculitic neuropathy rarely presented as large myelinated nerve fiber disease. It should be considered the clinical variability of vasculitic neuropathy so extensive studies are needed in the case of peripheral polyneuropathy with indefinite cause.

Malignant fibrous histiocytoma is a rare malignant tumor of probably histiocytic origin. It is more common in soft tissue than bone. Usually it involves metaphysis or diaphysis of long bone. Primary spinal malignant fibrous histiocytoma is exceedingly rare. Authors report a case of primary malignant fibrous histiocytoma which showed rapid spinal cord compression in thoracic spine with review of literatures.

Garcin's syndrome is defined as showing total unilateral cranial nerve palsies (at least more than 7 ipsilateral cranial nerve palsies), without either sensory or motor long tract disturbance, and without intracranial hypertension. The present report describes an 8-year-old child who had swelling on the right postauricular area and ptosis on the same side which developed before 2 months ago. Neurologic examination disclosed complete unilateral cranial nerve palsies on the right side. Brain MRI revealed a bulky hypervascular well-enhancing solid tumor, involving the right temporal bone, middle cranial fossa, cerebellopontine angle, infratemporal and pterygopalatine fossae, and parapharyngeal space. A biopsy was performed, and its finding showed a chondrosarcoma.

Pyogenic sacroiliitis is a rare infection that may accompany psoas muscle abscess with vague clinical presentation, which present a diagnostic challenge requiring a high index of suspicion. We report a 48-year-old male, diagnosed pyogenic sacroiliitis with psoas abscess caused by Streptococcus intermedius and Sphingomonas paucimobilis. Magnetic resonance imaging showed multiloculated rim-enhancing lesion in right psoas muscle and joint effusion with osteomyelitis around sacroiliac joint. Intravenous antibiotics were administered after ultrasonographically guided abscess aspiration. Surgical drainage was done and his fever and symptom gradually subsided.

We analyzed the practical problems and factors which affect making the correct differential diagnosis in the interpretation or test results from the nocturnal penile tumescence (NPT) test and erotic stimulation test (EST). This was done to provide better information for higher diagnostic accuracy in the clinical application of these tests. The followings are the results of NPT tests and EST identifying the factors affecting correct differential diagnosis by comparison the other differential diagnostic methods. The overall sensitivity of NPT test (Number: 114 total patients) was 82%. 21 cases (18%) could not be diagnosed correctly due to traction of the sensor (12 cases, 10%) and sleep disturbance (9 cases, 8%). The overall sensitivity of EST (Number: 174 total patients) without considering the degree of patient`s sexual drive to erotic stimulation was 77%. 40 cases (23%) could not be diagnosed correctly due to tolerance to pornographic film (17 cases, 10 %), discomfort by the body attachments (14 cases, 8%) and traction of the sensor (9 cases, 5%). However, higher sensitivity (90%) and lower rate of incorrect diagnosis (10% ) were observed in 119 patients who showed Grade II or III (moderate to good) sexual drive to erotic stimulation. The results suggest that undesirable factors in the primary screening methods, traction of sensor, sleep disturbance in NPT test, and tolerance to pornographic film, discomfort by the body attachments, traction of sensor in EST must be taken into consideration when interpretation of test results is being performed.

BACKGROUND: Increasing degrees of medullary hyperemia induced by ischemia reperfusion injury were associated with renal dysfunction. A possible mechanism may be that ischemia causes alterations in the structure and function of vascular membranes which leads to an aggregation of red blood cells in the medullary vessel. It has been shown that heparin prevents postischemic endothelial cell dysfunction. Aim of this study was to evaluate heparin effects on renal hyperemia induced by ischemia reperfusion injury. METHOD: In this study, fifteen rabbits were randomized to either heparin treatment group(500 IU/kg IV bolus 10 minutes before renal artery occlusion, n=8) or control group(n=7). One side kidney underwent 60 minutes ischemia only by clamping renal pedicle and after that kidney tissue sample was obtained for histologic evaluation. The other side of kidney were permitted 60 minutes ischemia following 60 minutes reperfusion and after that kidney tissue sample was obtained for histologic evaluation. RESULTS: There was significant difference in the degree of congestion(2.6+/-0.2 vs 1.1+/-0.3, P<0.05) between outer medulla of control and heparin treatment group. CONCLUSION: Heparin significantly attenuated outer medullary congestion induced ischemic injury.

BACKGROUND: Insulin induced hypoglycemia has been used to assess the adrenocortical function, but may be hazardous. The standard rapid ACTH stimulation test has been advocated as a substitute but is sometimes insensitive. In this study, low dose (1ug) rapid ACTH stimulation test was compared to insulin induced hypoglycemia and standard dose (250ug) rapid ACTH stimulation. METHODS: 27 patients (14 men and 13 women) with pituitary disease and definite adrenocortical dysfunction (14 patients were confirmed by insulin induced hypoglycemia) and 23 controls (pituitary control: 3 men and 7 women, confirmed by insulin induced hypoglycemia, normal control: 8 men and 5 women) were studied. All subjects underwent rapid ACTH stimulation test with 2 different level of stimulation (1 and 250ug). Serum cortisol levels were measured at 0, 30 and 60 min after each dose of ACTH injection. A normal response was defined as a peak cortisol value of 497nrnol/L (18ug/dL) or above, RESULTS: During rapid ACTH stimulation study in controls, the peak serum cortisol level was significantly lower (690+-25lnmol/L (25.0+-9.1ug/dL) vs. 933+-257nmol/L (33.8+-9.3ug/dL); p< 0.01) and the peak appeared earlier (30min. vs. 60min) after the administration of low dose ACTH than after standard dose. However, the serum cortisol level at 30min was not different. In patient group, each serum cortisol level at 30min and 60min had no difference between low and standard dose (p>0.1). None of these 27 patients showed normal response to low dose stimulation, but 2 of 27 did to standard dose. In controls, 19 of 23 showed normal response to low dose, and all of 23 did to standard dose (sensitivity 100% vs 92.5%, specificity 82.5% vs 100%). The results of low and high dose stimulation test agreed with those of insulin induced hypoglycemia (Kendalls g= 0.50 vs 0.92, p<0.01 vs 0.001). CONCLUSIONS: The results of a low dose (1ug) rapid ACTH stimulation test showed good correlation with those of the standard dose (250ug) rapid ACTH stimulation test and insulin induced hypoglycemia. Thus it may be used in screening for the diagnosis of adrenal insufficiency.
