Association between exposure to a stenching agent in a herbicide packing plant and the occurrence of headache and lethargy.

This study quantifies the relationship between subjective complaints of symptoms and certain work activities and exposures in a plant where herbicide is packed. Data relating to symptoms were collected from 27 subjects (20 men and 7 women) on a daily basis with the use of a questionnaire. In addition, data were collected relating to work activity and exposure to the stenching agent added to the herbicide, atmospheric levels of which were measured with personal monitoring, on a daily basis. Although associations were found between the occurrence of lethargy and certain factors of job history, there was no significant association with exposure to the stenching agent as measured by personal monitoring during the study.

December 1998--16 year old female with headaches, lethargy and a sellar/suprasellar mass.

A 16 year female with a history of developmental delay and shunted hydrocephalus presented with two months of progressive headaches, lethargy and visual disturbances. An MRI of the brain revealed a sellar and suprasellar cystic mass which was absent on a previous MRI six years earlier. The pre-operative clinical diagnosis was pituitary adenoma vs. craniopharyngioma. Histologically, the fibrous wall of the ciliated epithelial-lined cyst was thickened by non-caseating granulomatous inflammation, hemorrhage, hemosiderin, and cholesterol clefts, consistent with cyst rupture. Rathke's cleft cysts are uncommon symptomatic lesions in young people, and must be distinguished from craniopharyngioma.

December 2000: 6 month old boy with 2 week history of progressive lethargy.

This 6-month-old Caucasian boy presented with a 10-day history of lethargy, obtundation, inability to hold his head up and mild torticollis. MRI and CT scans showed a large solid and cystic mass involving the right temporal, parietal and occipital lobes, pineal, superior pons, mesencephalon and posterior right thalamus. He underwent craniotomy initially for a partial tumor resection with an intraoperative diagnosis of desmoplastic astrocytoma. With immunohistochemistry and special stains the diagnosis of desmoplastic infantile ganglioglioma (DIG) was made. A near total resection was performed a week after initial resection.The patient then was treated with chemotherapy. Two months later an MRI showed tumor growth. Following additional aggressive chemotherapy, an MRI at 5 months post-resection indicated further tumor progression. This case illustrates that some DIGs may behave more aggressively than typical WHO grade I lesions.

Drosophila melanogaster as an experimental host for study of multiplication and biology of the mycoplasma inducing the "lethargy of coleoptera".

The mulitplication of the mycoplasma responsible for the "lethargy of coleoptera" on a laboratory host, Drosophila melanogaster, was obtained on the first passage. Independant series of successive passages on D. melanogaster were performed without any apparent modifications of the properties of the microorganism. Pathogenicity for its natural host Melolontha melolontha was retained. The different forms of mycoplasma observed lead us to propose a probable cycle of development, composed of a succession of globular and rod-shaped bodies, these later being often sinuous. The infected Drosophila flies presented a reduced life span and fertility. Infection of the cephalic nervous system seems to be responsible for death. Horizontal transmission of the microorganism was not observed.

[Overdosage of glibenclamide presenting with lethargy and seizures in a child].

Management of accidental overdosage with oral hypoglycemic agents in toddlers may be difficult when the history of ingestion is overlooked. We report a 21-month-old girl who presented with lethargy and generalized seizures 12 hours after ingestion of an unknown number of glibenclamide pills. The blood glucose on admission was 0.5 mM/l. Symptoms resolved promptly after an intravenous bolus of glucose. Metabolic and infectious causes of hypoglycemia were ruled out. The parents denied drug ingestion initially, but further investigation revealed that she had ingested several glibenclamide pills used by her diabetic father 12 hours prior to admission. This case illustrates the problem involved in diagnosis and management of accidental drug overdosage in children when no such history is elicited and symptoms are delayed.

[Hypotonia and lethargy: initial manifestations of a new case of galactosemia].

INTRODUCTION: Galactosemia is a metabolic disease that is transmitted by autosomal recessive inheritance in which there is an enzymatic deficit that prevents the metabolism of galactose. Three enzymes could be involved, but the lack of galactose-1-phosphate uridyltransferase (GALT) is the most frequent. Incidence is two cases per 100,000 newborn infants. As a consequence of this enzymatic deficit, on ingesting milk the newborn infant will present a progressive neurological deterioration, cataracts and digestive tract and kidney disorders. An early diagnosis is essential so that galactose can be withdrawn from the diet as soon as possible, which in the newborn infant means discontinuing mother's milk and feeding with galactose-free milk. CASE REPORT: We report the case of a newborn female, the daughter of consanguineous parents (second cousins) from the gypsy ethnic group, who was diagnosed as suffering from galactosemia with a total GALT deficit. The patient was given normal milk for the first 10 days of her life and presented hypotonia, lethargy, jaundice, hepatomegaly, refusal to eat, low weight gain and a urinary infection caused by gram negative bacteria. Following diagnosis, galactose was withdrawn from the diet (she was given soy milk) and the physical exploration became progressively more normal. CONCLUSIONS: This is an extremely unusual pathology, but the patient's outcome is largely dependent on an early diagnosis and treatment.

Diaphragmatic herniation as a cause of lethargy and exercise intolerance in a mare.

A diaphragmatic hernia in which 90% of the large colon had herniated through a 16-cm linear tear in the diaphragm was found in a 12-year-old Quarter Horse mare. Clinical signs included lethargy and exercise intolerance. Diagnosis of diaphragmatic hernia was made based on careful thoracic auscultation, combined with ultrasonographic and radiographic examination of the thorax.
