Lumbar Myelopathy Caused by Multiple Cartilaginous Exostoses in a Dog

A 6-months-old male mixed-breed dog was admitted to the veterinary hospital with lameness in the right pelvic limb, proprioceptive ataxia, and suspected spinal cord injury in the lumbosacral segment. Upon palpation, firm nodules were noted on the bony surface of the thoracic and pelvic limbs, ribs, vertebrae, and tail. The radiographic study showed nodules of low radiopacity with well-defined limits and smooth contours, one of which was overlapping the fifth lumbar vertebra. Given the clinical presentation indicative of spinal cord injury, the animal was subjected to hemilaminectomy for nodular resection. Histopathological examination of the biopsy enabled the diagnosis of osteochondroma. The clinical follow up after surgery showed improvement in walking, despite persistent monoparesis in the right pelvic limb. The radiographic study in association with clinical and histopathological exams allowed the diagnosis and monitoring of the lesions.

HIV and Headache: A Cross-Sectional Study

INTRODUCTION

The head and neck are the second most common locations for pain among HIV-positive individuals. Most studies were conducted among HIV patients at an advanced stage of the disease.

METHODS

This was a cross-sectional study. Patients with HIV and CD4+ T lymphocyte counts >500 were included. Semi-structured interview, the Headache Impact Test (HIT-6), and the Hospital Anxiety and Depression Scale were used.

RESULTS

Of the 119 cases included, 63% were men. The mean age was 35.5 ± 10.4 years. Among the patients, 103 (87%) had headaches, 53 (45%) had migraines, 50 (42%) had tension-type headaches, and 53 (45%) had substantial and severe impact of headaches. Eleven patients had headaches that started after they had been diagnosed with HIV. These patients had more migraines (72% vs 43%; P < 0.05), greater intensity (8 ± 2 vs 6 ± 2; P < 0.01), and impact (HIT-6: 60 ± 11 vs 51 ± 12; P = 0.02) of headaches compared to others HIV patients. There were no correlations between CD4 counts and the intensity, frequency, or impact of headaches.

CONCLUSIONS

HIV-positive patients had a high frequency of headaches, which had a great impact on patients' lives. The pattern most often found was migraine. There was no correlation between CD4 counts and the severity of headaches.

Migraine, Osmophobia, and Anxiety

OBJECTIVES

To evaluate the association between osmophobia and the characteristics of patients and their headaches, among migraine patients.

METHODS

This was a cross-sectional study. Patients who consecutively sought medical attendance in a primary care unit were asked about their headaches over the last 12 months. Those who had migraine were included. A semi-structured interview, the Headache Impact Test and the Hospital Anxiety and Depression Scale were used.

RESULTS

147 patients had migraine; 78 had osmophobia; 60 had significant anxiety symptoms; and 78 had significant depression symptoms. The mean age of these patients was 43.2 years (± 13.7); 91.2% were women. The mean length of time with complaints of headache was 13.8 years (± 12). Among the migraine patients, those with anxiety, more years of headache history, and phonophobia presented significantly more osmophobia (multivariate logistic regression).

CONCLUSION

Osmophobia in migraine patients is associated with significant anxiety symptoms, length of headache history, and phonophobia.
