Distúrbios do movimento em 28 pacientes infectados pelo HIV
Academia Brasileira de Neurologia - ABNEURO, 2002Co-Authors: James Pitágoras De Mattos, Ana Lúcia Zuma De Rosso, Corrêa, Rosalie Branco, Novis, Sérgio A.p.Abstract:From 1986 to 1999, 2460 HIV-positive inpatients were seen in our Hospital. Neurological abnormalities were detected in 1053 (42.8%) patients. In this group, 28 (2.7%) had involuntary movements, 14 (50%) with secondary parkinsonism, six (21.4%) with hemichorea/Hemiballismus, four (14.2%) with myoclonus, two (7.2%) with painful legs and moving toes, one (3.6%) with hemidystonia and one (3.6%) with Holmes' tremor. The HIV itself (12 patients), toxoplasmosis of the midbrain (1) and metoclopramide-related symptoms (1) were the most probable causes for the parkinsonism. All patients with hemichorea/Hemiballismus were men and in all of them toxoplasmosis of the basal ganglia, mostly on the right side, was the cause of the involuntary movements. Generalized myoclonus was seen in two patients and they were due to toxoplasmosis and HIV-encephalopathy respectively; two others presented with spinal myoclonus. The two patients with painful legs and moving toes had an axonal neuropathy. The patient with hemidystonia suffered from toxoplasmosis in the basal ganglia and the patient with Holmes' tremor had co-infection with tuberculosis and toxoplasmosis affecting the midbrain and cerebellum. We conclude that HIV-infected patients can present almost any movement disorder. They can be related to opportunistic infections, medications, mass lesions and possibly to a direct or indirect effect of the HIV itself.De 1986 a 1999, 2460 pacientes HIV-positivos internados foram avaliados em nosso Hospital. Alterações neurológicas foram encontradas em 1053 (42,8%). Neste grupo, 28 (2,7%) exibiam movimentos involuntários, 14 (50%) com parkinsonismo secundário, seis (21,4%) com hemicoréia/hemiballismo, quatro (14,2%) com mioclonias, dois (7,2%) com painful legs and moving toes, um (3,6%) com hemidistonia e um (3,6%) com tremor de Holmes. No grupo com parkinsonismo, 12 eram, provavelmente, secundários ao HIV; um à toxoplasmose mesencefálica e outro desencadeado pela metoclopramida. Todos com hemicoréia/hemiballismo eram homens e estavam relacionados com toxoplasmose nos gânglios da base. Nos quatro pacientes com mioclonia, em dois era generalizada, relacionada, em um, com toxoplasmose e, em outro, com a encefalopatia pelo HIV; nos outros dois era de origem medular. Nos dois pacientes com painful legs and moving toes, ficou demonstrada a neuropatia axonal pela biópsia do nervo periférico. Toxoplasmose da gânglia basal estava relacionada com hemidistonia contralateral. No paciente com tremor de Holmes havia lesões no mesencéfalo e no cerebelo, secundárias à co-infecção pelo bacilo da tuberculose e pelo Toxoplasma gondii. Concluímos que diversos distúrbios do movimento podem ocorrer em pacientes infectados pelo HIV. Costumam estar relacionados às infecções oportunísticas, ao uso de certos medicamentos, às lesões com efeito de massa e, possivelmente, à ação direta ou indireta do HIV

Clinical vignette: Hyperglycemic hemichorea Hemiballismus: a sugar coated movement disorder
2013Co-Authors: Salas, Natalie Mariam, Khashaei SepehrAbstract:Presented at American College Physicians national meeting, 04/11/2014, Orlando, FL. Winner of resident competition. American College of Physicians New Mexico Chapter Scientific Meeting, 10/18/2013, Albuquerque, NM.An 86 year-old man with type II diabetes, coronary artery disease and anxiety presented to the emergency department with insomnia and restlessness for 3 days duration. The patient claimed to be feeling increasingly anxious and initially sought treatment at an outpatient psychiatric urgent care. He was referred to the emergency department when his blood glucose was found to be above 500 mg/dL. The patient claimed to be taking his long-acting insulin at home but his inability to concentrate made him a poor historian. On examination he appeared dehydrated and disheveled. Physical examination was unrevealing except for abnormal jerking, twitching and writhing of his right upper and lower extremities. His inpatient laboratory findings initially revealed serum blood glucose of 348 mg/dL, a hemoglobin A1C greater than 18% and pseudo-hyponatremia at 129 mmol/L. All other labs were unremarkable. The patient was admitted for treatment of non-ketotic hyperglycemia and evaluation of his abnormal involuntary extremity movements. Urine toxicology screen, thyroid stimulating hormone, vitamin B12 and folate levels were normal. His movements were assumed to be due to insomnia and a possible psychiatric illness but failed to resolve with sleep medication and anxiolytics. The patient underwent a brain CT scan and MRI that revealed hyper-attenuation of the left putamen. This finding, with the patient’s unilateral involuntary jerking in the setting of non-ketotic hyperglycemia lead to the diagnosis of hyperglycemic hemichorea Hemiballismus. The patient was treated with glycemic control and short-term clonazepam. His hemichorea resolved after 3 weeks of appropriate glycemic control and clonazepam was discontinued. Hemichorea Hemiballismus is a rare and fascinating complication of prolonged hyperglycemia. It typically occurs in elderly type II diabetics and is more common with those of Asian decent. The brain image findings described in our patient are classic for this disease. The pathophysiology of this condition is poorly understood but biopsy of the basal ganglion lesions reveals swollen astrocytes. Symptoms are usually unilateral and typically resolve completely with glucose control, as do the findings on brain imaging. This striking disorder is diagnosed by typical MRI findings in the setting of hyperglycemia. Because it is reversible, physicians should be aware of this rare and disabling form of chorea so as not to mistake it for psychiatric disease or more serious forms of chorea such as Huntington's

Distúrbios do movimento em 28 pacientes infectados pelo HIV
Academia Brasileira de Neurologia - ABNEURO, 2002Co-Authors: James Pitágoras De Mattos, Ana Lúcia Zuma De Rosso, Corrêa, Rosalie Branco, Novis, Sérgio A.p.Abstract:From 1986 to 1999, 2460 HIV-positive inpatients were seen in our Hospital. Neurological abnormalities were detected in 1053 (42.8%) patients. In this group, 28 (2.7%) had involuntary movements, 14 (50%) with secondary parkinsonism, six (21.4%) with hemichorea/Hemiballismus, four (14.2%) with myoclonus, two (7.2%) with painful legs and moving toes, one (3.6%) with hemidystonia and one (3.6%) with Holmes' tremor. The HIV itself (12 patients), toxoplasmosis of the midbrain (1) and metoclopramide-related symptoms (1) were the most probable causes for the parkinsonism. All patients with hemichorea/Hemiballismus were men and in all of them toxoplasmosis of the basal ganglia, mostly on the right side, was the cause of the involuntary movements. Generalized myoclonus was seen in two patients and they were due to toxoplasmosis and HIV-encephalopathy respectively; two others presented with spinal myoclonus. The two patients with painful legs and moving toes had an axonal neuropathy. The patient with hemidystonia suffered from toxoplasmosis in the basal ganglia and the patient with Holmes' tremor had co-infection with tuberculosis and toxoplasmosis affecting the midbrain and cerebellum. We conclude that HIV-infected patients can present almost any movement disorder. They can be related to opportunistic infections, medications, mass lesions and possibly to a direct or indirect effect of the HIV itself.De 1986 a 1999, 2460 pacientes HIV-positivos internados foram avaliados em nosso Hospital. Alterações neurológicas foram encontradas em 1053 (42,8%). Neste grupo, 28 (2,7%) exibiam movimentos involuntários, 14 (50%) com parkinsonismo secundário, seis (21,4%) com hemicoréia/hemiballismo, quatro (14,2%) com mioclonias, dois (7,2%) com painful legs and moving toes, um (3,6%) com hemidistonia e um (3,6%) com tremor de Holmes. No grupo com parkinsonismo, 12 eram, provavelmente, secundários ao HIV; um à toxoplasmose mesencefálica e outro desencadeado pela metoclopramida. Todos com hemicoréia/hemiballismo eram homens e estavam relacionados com toxoplasmose nos gânglios da base. Nos quatro pacientes com mioclonia, em dois era generalizada, relacionada, em um, com toxoplasmose e, em outro, com a encefalopatia pelo HIV; nos outros dois era de origem medular. Nos dois pacientes com painful legs and moving toes, ficou demonstrada a neuropatia axonal pela biópsia do nervo periférico. Toxoplasmose da gânglia basal estava relacionada com hemidistonia contralateral. No paciente com tremor de Holmes havia lesões no mesencéfalo e no cerebelo, secundárias à co-infecção pelo bacilo da tuberculose e pelo Toxoplasma gondii. Concluímos que diversos distúrbios do movimento podem ocorrer em pacientes infectados pelo HIV. Costumam estar relacionados às infecções oportunísticas, ao uso de certos medicamentos, às lesões com efeito de massa e, possivelmente, à ação direta ou indireta do HIV
