[Influence of diabetes mellitus in hospital emergencies].

A study performed at the Internal Medicine Emergency Department of the General Hospital "La Paz" (Madrid) over a six month period is presented. Its goal was to check the problems of the diabetic patient at his entrance to the medical emergency. We review the emergency pathological causes and we established that vascular (32%) and acute metabolic (17%) alterations were the most common pathologies, both in insulin-dependent (IDDM) and non-insulin-dependent (NIDDM) diabetic patients. We analyzed the acute metabolic alterations considering that they can be foreseeable with an adequate knowledge of the disease. We point out an aspect that to our knowledge is basic: the diabetological information-education of diabetic patients (only 5% had a good knowledge of the disease and, furthermore, only 18% declared to have received some diabetological information). We also highlight the overuse that diabetic patients do of the hospital emergency departments, as a consequence of the previously mentioned poor information received which also reflects the insufficient or inadequate medical assistance in Primary Care Centers.

Chronic pachymeningitis associated to hypereosinophilia: case report.

A male 22 years old patient who consulted due to headache and increasing visual loss is being presented. Alterations in the exam were represented by right amaurosis and left temporal hemianopsis. Pathological and tomographical studies revealed chronic pachymeningitis with eosinophilic infiltration. An elevated eosinophilia and an increasing in anti-A and anti-B isoagglutinins were associated to the clinical course. They returned to normal values after treatment with tiabendazol. Even though there is not a certain conclusion as regards the etiology, the probable parasitary nature of the process is outlined.

[Evaluation of central and peripheral factors in muscular fatigue].

Muscular fatigue was investigated in 13 healthy people by employing a simple device which comprises a computer on line with a conventional EMG equipment able to automatically measure the frequency and duration of free-run EMG recording. The procedure was carried out in the extensor digitorum brevis muscle by using surface electrodes throughout 10 minutes of voluntary maximal effort. The maximal M wave as well as the muscle response to repetitive nerve maximal stimulation was also explored at the beginning and at the end of the experiment. It was observed a decrease of the potentials frequency discharge and an increase of their duration without major changes in the M wave amplitude neither in the muscle response to the repetitive nerve discharge. The findings pointed out to the central factors as the mean responsible for the development of muscular fatigue.

[Evaluation of central and peripheral factors in muscular fatigue in patients with pyramidal lesions].

Muscular fatigue mechanisms were partially analyzed in patients with pyramidal lesions by using a computer device on line with a conventional electromyograph. Both the normal and the affected side were compared with control groups. The recordings were done throughout a ten minutes period and the maximal M wave was also measured at the starting and at the end of the procedure. The findings suggested that central events play a major role in the development of muscular fatigue in spastic muscles due to pyramidal damage.

[Evaluation of central and peripheral components of muscular fatigue in neuropathic and myopathic patients].

In a group of patients chronically denervated and other with primary muscle involvement a search was made for mechanisms involved in the muscular fatigue. It was found that there was no major differences between patients chronically denervated and controls, while in those others with primary muscle disorders a loss of functional motor units during effort and a transient impairment of neuromuscular transmission play a role together with the central events normally occurring in fatigue.

[Hepatic abscess demonstrated by 67Ga-citrate scintigraphy within a diagnosis of fever of unknown origin].

We report a case of a 63 year old man who was seen in the hospital because of fever having a possible infectious or oncological origin. A 67Ga scintigraphy was performed and showed high pathological accumulation in the hepatic dome. The patient was re-evaluated and studied with other diagnostic tests including a CT scan, coinciding with the findings in the 67Ga-citrate scintigraphy. A correct final diagnosis of liver abscess was made.

Keratitis, ichthyosis, and deafness (KID) syndrome in half sibs.

The keratitis, ichthyosis, and deafness (KID) syndrome is a rare congenital disorder of the ectoderm characterized by diffuse hyperkeratotic erythroderma, keratitis with neovascularization of the cornea, and severe neurosensory hearing loss. A familial occurrence of this syndrome has been mentioned in four reports including three of vertical transmission and one of two affected sisters born from consanguineous, unaffected parents. We report for the first time a familial case of KID syndrome in two half siblings born to the same unaffected mother. This new observation allows us to propose various hypotheses about its mode of inheritance.
