Vibrio anguillarum is the most frequently isolated bacterial species involved in ulcer disease in salt water fish. However, an Aeromonas species was very often incriminated in ulcers and septicaemia in cods (Gadus morhua) in Danish coastal areas. These Aeromonas strains were very uniform in their biochemical activities only differing in growth on Simmons citrate agar, and the mean value for the guanine + cytosine content of DNA was 59 per cent with a standard deviation of 0.4. Primary serological investigations demonstrated a possible identity to O and K antigens. The most characteristic biochemical features of these strains were a gas production from glycerol but not from glucose. They were positive in lysine decarboxylase, did not produce indole, and had a typical fermentation pattern of the glycosides. Negative results were found in H2S production, phosphatase and in the utilization of NH4+ and glucose as the only source of N and C. The evident differences from the species described and subspecies of Aeromonas elucidate the weakness of the existing systems of biotyping. A broader conception of the biochemical spectrum for the individual species of Aeromonas combined with serotyping would seem to be a better system for identification, and also for an epidemiological purpose.

From 1984 to 1989, 112 patients with typical drug-refractory trigeminal neuralgia were treated by retrogasserian glycerol injection. The present study assesses results and complications after a mean follow-up period of 3.5 years (range 0.1-5.5 years). One hundred and three of 112 patients (91.9%) showed complete pain relief 1 month postoperatively, and at the end of follow-up 80 patients (71.4%) were still enjoying complete pain relief (recurrence rate 20.5%). Abnormal facial sensations were noted in 49 patients, the most common complication being mild hypoesthesia (32% of patients), while paresthesia occurred in 19% of cases and dysesthesia in 3%. The corneal reflex was absent in 3% of patients and reduced in 5%. None of the patients developed anesthesia dolorosa, permanent masseter weakness, neuroparalytic keratitis, or diplopia.

Brain metastases are rare in well-differentiated thyroid carcinoma but when present they can lead to the patient's death. Iodine-131 therapy for intracerebral thyroid carcinoma metastases causes radiation-induced acute cerebral edema that can lead to CNS complications and even death. We present a case in which a patient with intracerebral 131I uptake developed seizures, slurred speech, and muscle weakness 12 hr following 131I therapy. The patient's CT scan, post-therapy, confirmed an intracranial metastasis with a significant amount of surrounding edema. Radiotherapists, when using external beam radiation to treat intracerebral metastases, commonly place these patients on steroids, glycerol, or mannitol prior to instituting therapy, to prevent complications from radiation-induced cerebral edema. This technique could be applied to 131I therapy of intracranial thyroid carcinoma metastases as well.

Twenty nine patients with trigeminal neuralgia were treated by retrogasserian glycerol injection method. Two of 29 were postherpetic and 27 were idiopathic trigeminal neuralgia. The mean age of these 27 was 65.2 years old ranging from 35 to 83 and the mean duration of symptoms was 7.6 years ranging from 6 months to 25 years. As previous surgical treatment there were 9 alcohol block, 5 thermorhizotomy of the Gasserian ganglion and one microvascular decompression. Twenty-two gauge needle was introduced into the trigeminal cistern via foramen ovale under the fluoroscopic control. Before injection of glycerol trigeminal cisternography using metrizamide of 300 mgI/dl was done to ascertain whether or not the needle tip was properly placed in the cistern. Patients' neck being flexed anteriorly, pure glycerol, amounting from 0.15 to 0.6 ml, was injected into the cistern with small increments through the needle. If the needle was inserted too deeply in the cistern, it is more probable that glycerol should escape from the cistern into the posterior fossa. So it was advisable that needle tip should be placed in the bottom of the cistern. When there was no pain relief, second injection was performed usually 7 days after the first injection. Complications were as follows; dysesthesia (81%), hypertension (70%), hypalgesia and hypesthesia (48%) headache (22%), ocular dysesthesia (11%), masseter weakness (7%), hyperalgesia (7%), attack of paroxysmal pain (7%). Most of these complications subsided within 8 weeks. Dysesthesia and hypalgesia that had persisted over 8 weeks were recognized in 30% of the cases.(ABSTRACT TRUNCATED AT 250 WORDS)

The metabolic response to human growth hormone (HGH) was studied in five obese subjects in the fed state and during prolonged (5-6 wk) starvation. In the fed state (three subjects), HGH induced an elevation in basal serum insulin concentration, a minimal increase in blood and urine ketone levels, and a marked reduction in urinary nitrogen and potassium excretion resulting in positive nitrogen and potassium balance. In prolonged fasting (four subjects), HGH administration resulted in a 2- to 3-fold increase in serum insulin which preceded a 50% elevation in blood glucose. Persistence of the lipolytic effects of HGH was indicated by a rise in free fatty acids and glycerol. The response differed markedly from the fed state in that blood beta-hydroxybutyrate and acetoacetate levels rose by 20-40%, resulting in total blood ketone acid concentrations of 10-12 mmoles/liter, ketonuria of 150-320 mmoles/day, and increased urinary potassium loss. The subjects complained of nausea, vomiting, weakness, and myalgias. Despite a 50% reduction in urea excretion during HGH administration, total nitrogen loss remained unchanged as urinary ammonia excretion rose by 50% and correlated directly with the degree of ketonuria. It is concluded that in prolonged starvation (a) HGH may have a direct insulinotropic effect on the beta cell independent of alterations in blood glucose concentration, (b) persistence of the lipolytic action of HGH results in severe exaggeration of starvation ketosis and interferes with its anticatabolic action by necessitating increased urinary ammonia loss, and (c) failure of HGH to reduce net protein catabolism in starvation suggests that this hormone does not have a prime regulatory role in conserving body protein stores during prolonged fasting.

Electronystagmographic (ENG) and audiologic findings were reviewed for 206 patients treated for Meniere's disease (MD) at the University of Washington Hospital over a 10-year period (1971-80). The most frequently seen ENG findings were unilateral caloric weakness (UW) in 49%, directional preponderance (DP) in 36%, and spontaneous and/or positional nystagmus (SN, PN) in 32%. ENG was normal in 25%. Bilateral caloric weakness (BW) occurred in 36% of patients with bilateral hearing loss. UW was reliably correlated with the side of audiometric involvement; after exclusion of bilateral cases, only 3% of patients showed UW contralateral to the ear with hearing los. Neither DP nor direction of SN or PN correlated at all with side of hearing loss. There was no significant correlation of severity of hearing loss (by pure-tone thresholds or speech discrimination score) with ENG abnormality (UW or DP). Glycerol-positive patients had significantly poorer hearing than glycerol-negative patients, but ENG findings were similar in the two groups.

We report a 49-year-old man who presented progressive dysarthria, dysphagia, and left hemiparesis. The patient was well until June 28th of 1993 when he noted 'weakness' in his both legs; despite his weakness, he could play golf on that day. In the beginning of July, he noted difficulty in swallowing solid foods. He was admitted to the neurosurgery service of our hospital on July 15th of 1993 and a neurologic consultation was asked on July 17th. Neurologic examination at that time revealed an alert but somewhat childish man who appeared to have some difficulty in paying attention to questions. He was disoriented to time and showed difficulty in recent memory and calculation. Higher cerebral functions were intact. The optic fundi were normal; pupils were isocoric and reacted to light promptly; ocular movements were intact, however, he showed difficulty in convergence. Facial sensation and facial muscles were intact. He had no deafness. He showed slurred speech and difficulty in swallowing solid foods. The remaining cranial nerves were intact. Motor-wise, he was able to walk normally and no weakness or atrophy was noted. Mild ataxia was noted in the finger-to-nose and the heel-to-knee test on the left. Muscle stretch reflexes were normal and symmetric, however, the plantar response was extensor bilaterally. Sensation was intact and no meningeal signs were noted. General routine laboratory findings were unremarkable. CSF was under a normal pressure containing 1 cell/microliter, 68 mg/dl of protein, and 54 mg/dl of glucose. Cranial CT scan showed low density areas involving the pons, midbrain, left thalamus, and the left parietal cortex. In MRI, these areas presented low signal intensity in T1-weighted images and high signal intensity in T2-weighted in images. The brain stem appeared swollen. Gadolinium enhancement was negative. He was given a course of steroid pulse with 1 g/day of DIV methylprednisolone for three days followed by oral steroid. He showed only temporary improvement in swallowing. In the subsequent course, he showed progressive deterioration in dysarthria and dysphagia. A biopsy was performed on the left parietal lobe lesion. After biopsy, he was treated with steroid and glycerol without improvement. A course of chemotherapy with procarbazine, MCNU, and vincristine was given; he did not respond to chemotherapy. His left hemiparesis deteriorated. He developed aspiration pneumonia from dysphagia and expired on October 22, 1993. The patient was discussed in a neurologic CPC, and the chief discussant arrived at the conclusion that the patient had astrocytoma grade III involving the pons, midbrain, thalamus, and the parietal cortex.(ABSTRACT TRUNCATED AT 400 WORDS)

We report a 55-year-old man with papilledema and multiple cranial nerve palsies. He was well until 52 years of age when there was an onset of progressive difficulty in initiating urination; he visited the urology service of our hospital where a diagnosis of prostate cancer was made; the cancer was invading the bladder and was metastasizing to lymph nodes and bones. He was treated with oochiectomy and estrogen preparations with some improvement in his symptoms. Two years later, he developed difficulty in urination again, and transurethral resection of the tumor was performed in 1991. In December 1991, he noted tingling and numb sensation in his left face, which had become progressive worse within the next one month, and he developed blepharoptosis and deafness all on the left side. He was admitted to the urology service on February 4, 1992, and a neurological consultation was asked. On physical examination, general findings were unremarkable, except for lymph node enlargements of about 0.5 to 1.0 mm in size in cervical and inguinal regions. On neurologic examination, he was alert with normal mental activities; higher cerebral functions were intact. He had normal vision and visual fields, however, papilledema was present bilaterally; pupils and light reactions were normal. Extraocular muscles were intact on the right side, however, moderate restriction was noted in the left eye in that all the extraocular muscles except for the medial rectus were weak; blepharoptosis was noted on the left; no nystagmus was present. The sensation was diminished in the left face, and left facial paresis of the peripheral type was also noted; the taste sensation was also diminished in the left anterior two thirds of the tongue. He had sensorineural deafness on the left side. The other cranial nerves appeared intact. He walked normally; no weakness or muscle atrophy was noted; muscle tone was normal and no ataxia was observed. Deep reflexes were normally elicited and symmetric; the plantar response was flexor. No meningeal signs were present. Laboratory examination revealed following abnormalities: Hb 7.1 g/dl, platelet 47,000/cmm, WBC3,800/cmm, LDH 950IU/l, PAP232ng/ml (normal less than 1.6), PA2.631ng/ml (normal less than 7.4); a small amount of effusion was noted in the left pleural cavity; cytological examination of the fluid was class V. A cranial CT scan as well as MRI were entirely normal, as was the spinal tap. He was treated with glycerol, however, there was progressive increase in the pleural effusion, and he developed dyspnea; moist rale had become audible in the end of February.(ABSTRACT TRUNCATED AT 400 WORDS)

We report a 70-year-old man who had a sudden onset of right hemiparesis and mutism. The lower extremity was more involved than the upper one. He had a long history of diabetes and chronic renal failure for which hemodialysis was necessary. On August 30, 1990, he had an sudden onset of right hemiparesis and mutism. Neurological examination revealed awake but mute in no acute distress. He could only respond to very simple commands such as opening his mouth or protruding his tongue. He did not appear to understand more difficult questions. In addition, he could not answer verbally. He was totally mute. Cranial nerves appeared intact except for slight right central facial paresis and severe diabetic retinopathy. He had complete paralysis of his right leg and a moderate weakness in his right upper extremity. Deep reflexes were diminished in both upper extremities and absent in the lower limbs. Frotal signs such as grasp and snout reflexes were present. Cranial CT scans revealed an ill-defined low density area in the left parasagittal subcortical area and a part of the anterior cerebral artery territory. The supplementary motor area appeared at least in part to be involved. He was treated with glycerol and other supportive cares, however, his clinical course was complicated by pneumonia, heart failure, septicemia, and he expired two months after his stroke. The patient was discussed in a neurological CPC, and the chief discussant arrived at a conclusion that he had an artery-to-artery embolism at the internal carotid bifurcation resulting in the cerebral infarction mainly in the territory of the anterior cerebral artery.(ABSTRACT TRUNCATED AT 250 WORDS)

Percutaneous retrogasserian glycerol rhizolysis (PRGR) became a diffuse and valuable method for treatment of trigeminal neuralgia, following its introduction by Hakanson in 1981. Its main advantages are: a) mild postoperative facial sensory loss, b) simplification of the technique, c) reduction of costs. Our results in a series of 191 patients treated between September 1983 and September 1990 are reported. The procedure was performed according to Hakanson's method with minor modifications. In 11 cases (5.7%) we failed to pierce the foramen ovale; the procedure was successfully repeated a week or two later. In 17 cases it was impossible to obtain CSF from the needle. Complete relief of pain was achieved in 177 patients (92.7%), in 124 (64.9%) immediately, in 53 (27.8%) within 6 days; the operation was unsuccessful in 14 (7.3%). Postoperative sensory evaluation showed: no sensory loss in 33 cases (17.3%); hypalgesia in 8 (4.2%); mild hypesthesia in 88 cases (46.1%), confined to the affected divisions in 45 (23.6%), exceeding it in 43 (22.5%); moderate hypesthesia in 62 cases (32.4%), restricted to the target divisions in 36 (18.8%), exceeding them in 26 (13.6%). No case of anesthesia occurred. Complications of PRGR were: circum-oral ipsilateral herpetic eruption (herpes simplex type), spontaneously and completely regressing: 63 cases (33%); minor dysesthesia, seldom reported as painful: 33 cases (17.3%); impairment of corneal reflex: 19 cases (9.9%), the first branch being the target of the treatment in 11; regressive masticatory weakness; 11 patients (5.7%); aseptic meningitis, promptly regressed: 2 cases (1.0%). Follow-up ranges from 1 to 7 years (Sept. 1983-Sept. 1990). A recurrence was observed in 44 cases (23%): in 15 patients (7.8%) a partial relapse occurred, well controlled by drug therapy and not requiring further surgical treatment; in 29 cases (15.2%) a new percutaneous procedure was required. The mean time of recurrence was 30.5 months. The recurrence rate in the patients of our series at the end of the follow-up period was 23%. Glycerol produces a weak neurolytic lesion, that generates minor post-operative facial deafferentation; it is the best technique, in our opinion, for treatment of tic douloreux.
