[Diagnosis of centronuclear myopathy in adults].

INTRODUCTION: Centro-nuclear myopathy is a congenital myopathy characterized by the presence of central nuclei on muscle biopsy. Three clinical forms have been distinguished. Classification depends on the type inherited, age of onset and degree of muscle involvement. CLINICAL CASE: We describe the case of a female patient in whom the diagnosis of centro-nuclear myopathy was made at the age of 53. The patient had not been studied previously, but was sent to us by the Department of Anaesthesia. The clinical features had first appeared in infancy. There was no family history of this disorder. Apparently this was a sporadic case. CONCLUSIONS: In the differential diagnosis of adult patients with girdle paresthesias centro-nuclear myopathy should be included. This unusual muscle disorder may be need to be considered if anaesthesia is required.

Multiple hidrocystomas.

Apocrine hidrocystoma is a cyst from the secretory portion of the apocrine sweat gland and tends to occur as a solitary facial lesion. We report a 66-year-old woman with multiple, cystic lesions on her face. Histopathology revealed cystic spaces lined by a row of secretory cells showing decapitation secretion. We emphasize the multiple character of the case and discuss its distinction from so-called eccrine hidrocystomas.

Lichen planus with predominant plasma cell infiltrate.

We herein report the case of a patient with lichenoid plaques on the lower extremities and anonychia of all toenails. Histologically, the eruption showed typical features of lichen planus, with the exceptional finding of a lichenoid infiltrate composed mostly of plasma cells. Only two other similar cases have been reported. The explanation for the numerous plasma cells remains unknown although such cases may represent a new histologic variant.

Fingertip tophi without gouty arthritis.

We report 2 patients without a history of acute gouty arthritis showing tophi located only on the fingertips, an unusual location. A review of the literature found a few similar reports; these patients might represent a subgroup of gout characterized by: (1) elderly patients, from the 7th to 9th decades; (2) hyperuricemia; (3) absence of a history of acute gouty arthritis; (4) tophi in the fingertips or fingerpads; (5) chronic renal failure, and (6) all taking drugs or suffering from a disease that affects urate renal excretion.

[The epidemiological transition in Chile].

Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage.

[Fasciola hepatica infestation. Biopathology and new diagnostic and therapeutic aspects].

We present here 6 patients with Fasciola hepatica infection, all from rural origin, and with the risk factors of eating wild watercress. The more common symptoms were: fever (83%), abdominal pain (100%), weight loss (83%) and generalized myalgia and joint pain (67%). All patients presented with an absolute eosinophil count above 1,000 cell/mm3. The diagnosis was established in five cases by means of serologic techniques (haemagglutination) and with direct visualization of adult worms while surgery in one case. A CT abdominal scan was performed in five patients, revealing specific lesions of tissue infiltration in four of them. Praziquantel was used in four patients, achieving clinical cure in three cases. In two patients, bithionol was used, with clinical cure in both cases. We review also some newer diagnostic and therapeutic approaches to this parasitic disease.

Behavior of calciotropic hormones in psoriasis.

This report was motivated by the finding that calciotropic hormones, except parathormone (PTH), do not show any response to 1a(OH)D3 therapy in psoriatic patients. These showed high basal whole PTH levels (127 +/- 38 pg/ml) which declined to 45 +/- 15 pg/ml after treatment (p less than 0.001) but did not correlate to calcemia values. Basal calcemia and calciuria were normal and rose with treatment (p less than 0.001 for both). Basal calcitonin and 25(OH)D3 were normal and did not change with treatment nor correlate to changes in calcemia. Due to the effect of 1-hydroxyvitamin D and calcemia on calcitonin and 25(OH)D, the lack of changes in the latter suggests a calciotropic hormone imbalance in psoriasis, which may be an etiologic factor in this entity.
