Diabetic polyneuropathy. Axonal or demyelinating?

Diabetic polyneuropathy is the most common subgroup of diabetic neuropathy, but its nature is controversial as it might be demyelinating and/or axonal. We have tried to determine whether diabetic polyneuropathy is electrophysiologically axonal, demyelinating, or both. We have studied the sural and peroneal nerves and the electromyographies of leg muscles in 50 healthy subjects (average age 67.2 years, range 45 to 84 years), in 50 diabetic patients (average age 66.34 years, range 44 to 82 years) showing no symptoms and/or signs of polyneuropathy (DP1), and in 50 diabetic patients (average age 67.10 years, range 49 to 87 years) showing symptoms and/or signs of polyneuropathy (DP2). The amplitude (AMP) of sural and peroneal nerves in healthy and DP1 subjects was similar. Conduction velocity (CV) of sural and peroneal nerves was slower in DP1 subjects than in healthy subjects. DP2 subjects showed AMP and CV values significantly lower than those in DP1 subjects, and signs of acute and chronic denervation/reinervation were found in the leg muscles. We believe that this result indicates that diabetic patients have two types of polyneuropathies: a demyelinating disease that could appear in diabetic patients with and without symptoms of polyneuropathy, and an axonal loss that is responsible for most of the symptoms.

Balint's syndrome. Report of four cases with watershed parieto-occipital lesions from vertebrobasilar ischemia or systemic hypotension.

Four patients with Balint's syndrome secondary to bilateral parieto-occipital ischemic lesions are presented. The pathogenesis of these lesions corresponded to either occlusive arterial disease in the vertebro-basilar system or the effects of systemic hypotension. The clinical features of this syndrome are discussed, along with the pathophysiology and time course of the condition, with particular emphasis on etiological factors, which make of this condition a distinct clinico-pathological syndrome.

[Adenocarcinoma in bladder exstrophy].

We present a case of vesical extrophy complicated by an adenocarcinoma in a 35-year old patient. It is this type of neoformation which most frequently affects the extrophic bladder and which, contrary to what has happened in most of the cases published, quickly presented bone and skin metastases.

[Statistics of urological infections in the hospital environment].

A review is made of the clinical histories of 1,821 patients admitted to our Department for treatment over a three-year-period and on the basis of the data compiled, the doctors have made a statistical study of urinary infections, by determining the type of germ, etiology of the process and level of sensitivity to the different antibiotics and chemiotherapeutic drugs and by analysing, at the same time, the inference between the different parameters considered. Of the results presented, they stress that the practical erradication of E. coli as an infecting agent in our medium, is significant, as well as the probable existence of an epidemiological cycle lasting for periods of twenty one months although this has still to be confirmed by means of longer chronological series.
