IS CARDIOVASCULAR DISEASE A RISK FACTOR IN THE DEVELOPMENT OF AXONAL POLYNEUROPATHY?

Objectives: To determine if cardiovascular disease may be a risk factor in the development of chronic idiopathic axonal polyneuropathy (CIAP). Methods: In this incidence case-control study, the prevalence of cardiovascular disease and risk factors in 97 patients with CIAP (mean age 67.5 (SD 7.9) years) and the prevalence of neuropathic features in 97 patients with peripheral arterial disease (PAD) (mean age 67.1 (SD 7.3) years) were investigated. The results were compared with those for 96 age and sex matched controls without diagnosed PAD or polyneuropathy (mean age 67.5 (SD 9.1) years). In a randomly chosen subgroup of 23. patients with CIAP, 42 patients with PAD, and 48 controls, an electrodiagnostic investigation was performed. Results: Patients with CIAP more often had manifest cardiovascular disease and cardiovascular risk factors than controls (stroke 18% v 6% of patients, odds ratio (OR) 3.2 (95% confidence interval (0) 1.8 to 5.9); heart disease 29% v 15%, OR 2.4 (95% Cl 1.2 to 4.9); family history of cardiovascular disease 42% v 21%, OR 2.8 (95% Cl (1.5 to 5.2); hypertension 56% v 39%, OR 2.0 (95% Cl 1.1 to I I 3.6); hypercholesterolaemia 46% v 21%, OR 3.3 (95% Cl 1.5 to 7.3); current smoking 38% v 23%, OR 2.1 (95% Cl I. I to 3.9)). The prevalence of cardiovascular disease and cardiovascular risk factors was lower than in patients with PAD. Patients with PAD more often had polyneuropathy than controls (15% v 5%, OR 3.3 (95% Cl 1.1 to 10.0)). There was a trend towards lower nerve conduction velocities and lower amplitudes on electrodiagnostic investigation compared with controls. Conclusion: This study shows that cardiovascular disease and CIAP often coexist, and therefore cardiovascular disease may be a cofactor in the development of CIAP.     

ARTHROSCOPIC EVALUATION AND MANAGEMENT OF MENISCAL INJURIES OF THE KNEE

50 cases of isolated meniscal injuries of the knee were evaluated and managed arthroscopically. 56% of the cases were in 25–35 year age group. In 80% of the cases military training and contact sports was the mode of injury. Maximum (42%) patients reported late (> 2 years) after the injury. On presentation, they had an average Lysholm knee score of 53.76. Medial meniscal lesion was seen in 74%. Commonest pattern of tear encountered was a longitudinal tear (40%). Depending on pattern and extent of lesion, partial meniscectomy (60%), subtotal meniscectomy (14%) and total meniscectomy (26%) were performed. Patients were followed up at six months and one year. The average Lysholm score at 6 months was 83.3 and at one year 79.5. At one year, the patient satisfaction level was 82% and patients who underwent partial meniscectomy had the best results.KEY WORDS: Arthroscopy, Meniscal tear     

Paraneoplastic Syndrome in Hawai‘i: A Case of Dermatomyositis Associated with Endometrial Cancer

Dermatomyositis as a paraneoplastic consequence of gynecological malignancy has rarely been reported in literature and never been reported in Honolulu. This case report describes a local Honolulu resident who was diagnosed with endometrial adenocarcinoma upon presenting with acute dermatomyositis symptoms.     

Neuromuscular features in Marfan syndrome

Marfan syndrome is a clinically and allelic heterogeneous, heritable connective tissue disorder with infrequently reported neuromuscular features. This study is the first to delineate these symptoms in a non-selected population. Neuromuscular involvement was evaluated in 10 Marfan patients through a standardized questionnaire, physical examination, nerve conduction study (NCS), needle electromyography (EMG), muscle ultrasound, laboratory investigation, and muscle biopsy. Existing neuroimages were screened for dural ectasia and spinal meningeal cysts. Twenty healthy controls with similar age distribution completed the questionnaire.
The results showed that various neuromuscular symptoms occur more frequently in the patients. Four older patients reported muscle weakness, five patients had a mild-to-moderate reduction in vibration sense, and all older patients mentioned mild functional impairments. NCS showed axonal polyneuropathy in four and EMG myopathic and neurogenic changes in all patients. Increased echo intensity and atrophy on muscle ultrasound was found in more than half of the patients. Muscle biopsies obtained in two patients showed myopathic changes in the older, female patient.
In conclusion, the majority of Marfan patients exhibited neuromuscular symptoms characterized as myopathy or polyneuropathy or both, and signs of lumbosacral radiculopathy, with symptoms being most pronounced in the older patients. Although meriting corroboration, these findings indicate a need to further the awareness of neuromuscular involvement in this population.
