The application of an electrophysiological bulbocavernosus reflex test in male dogs.

The electrophysiological bulbocavernosus reflex test consists of recording the electromyographic activity of the bulbocavernosus muscle following electrical stimulation of the glans penis. This study has been carried out to show the applicability of the electrophysiologic bulbocavernosus reflex (EBCR) in dogs and to determine its normal latency value. Ten healthy male dogs were used. Responses to stimulation of the bulbus glandis were recorded from the left bulbocavernosus muscle with a concentric needle-recording electrode. In 10 dogs of maximum size 31 kg and maximum age 3 years, EBCR had response latencies between 17.6 and 28.8 ms with the mean value of 24.4 ms. The results of this study show that the electrophysiological bulbocavernosus reflex test could be employed as a routine diagnostic method in small animal clinics for evaluation of the sacral reflex arc. Among several advantages are easy applicability and the objective result, with the latency exceeding 29 ms not being seen in the dogs used in our study.

Partial seizure: an unusual cause of recurrent vomiting.

Partial seizure is a rare cause of nausea and vomiting. We report an adult patient with abdominal discomfort lasting 15 years accompanied by nausea and vomiting at least twice a week. On admission, physical examination and detailed laboratory tests were normal. Abdominal ultrasound examination, upper gastrointestinal endoscopy and CT scanning of the brain did not reveal any evidence of disease. Electroencephalography revealed bilateral synchronous sharp wave discharges and spike wave activities. The diagnosis of partial seizure was considered and the patient was administered sodium valproate. The patient's symptoms subsided and he has been asymptomatic for the past 20 months. We conclude that partial seizure should be considered in patients suffering from abdominal complaints who do not have any underlying gastrointestinal disorder.

Open pilot study on oxcarbazepine for the treatment of notalgia paresthetica.

Notalgia paresthetica is a sensory neuropathy typically presenting with pruritus on the back. There is currently no effective treatment for this disorder. We describe a single patient who responded to oxcarbazepine, and a subsequent trial in another 4 who also responded. Although the number of patients in our study is small, we believe further trials are warranted to determine the efficacy of oxcarbazepine in this disorder.

Notalgia paresthetica: a study on pathogenesis.

BACKGROUND: Notalgia paresthetica is a sensory neuropathy involving the dorsal spinal nerves. The characteristic symptom is pruritus on the back, occasionally accompanied by pain, paresthesia, and/or hyperesthesia, which results in a well-circumscribed hyperpigmented patch in the symptomatic area. The etiology of this condition has not yet been completely defined. OBJECTIVE: Possible mechanisms that could explain the pathogenesis of notalgia paresthetica were investigated through clinical examination and various diagnostic tests. METHODS: Ten cases of notalgia paresthetica underwent dermatologic, neurologic, and orthopedic examination. This was followed by skin biopsy, electrodiagnostic investigation, and radiography of the spine. RESULTS: All patients had a typical symptomatology and dermatologic picture. Neurologic examination and standard electrodiagnostic investigation results were normal in all cases. Histopathology was compatible with postinflammatory hyperpigmentation; there were no amyloid deposits. In seven cases, degenerative changes in the vertebrae were observed and, in all of these cases, these changes were most prominent in the vertebrae which corresponded to the dermatome of the cutaneous lesion. CONCLUSIONS: The striking correlation of notalgia paresthetica localization with degenerative changes in the spine suggests that spinal nerve impingement may contribute to the pathogenesis of this entity.

Repeated hypoglycemia and cognitive decline. A case report.

OBJECTIVE: Diabetes mellitus has a high incidence in general population and goes by high morbidity by specific micro vascular pathology in the retina, renal glomerul and peripheral nerves. In type 1 DM, intensive therapy can prevent or delay the development of long-term complications associated with DM but hypoglycaemia especially severe hypoglycaemia defined, as a low blood glucose resulting in stupor, seizure, or unconsciousness that precludes self-treatment is a serious threat. Hypoglycaemia that may preferentially harm neurons in the medial temporal region, specifically the hippocampus, is a potential danger for the brain cognitive function which several studies failed to detect any significant effects, whereas others indicated an influence on it. A young diabetic case presented here with severe cognitive defect. Great number of severe hypoglycaemic or hyperglycaemic attacks and convulsion episodes were described in his medical history. RESULTS AND CONCLUSION: Neuroradiologic findings on CT and MRI, pointed that global cerebral atrophy that is incompatible with his age. Brain perfusion studies (SPECT, (99m)Tc-labeled HMPAO) also showed that there were severe perfusion defects at superior temporal region and less perfusion defects at gyrus cingulum in frontal region. These regions are related with memory processing. Severe cognitive defect in this patient seems to be closely related these changes and no another reason was found to explain except the repeated severe hypoglycaemic episodes.
