Pulmonary distress following attempted suicidal hanging.

OBJECTIVE : To assess the incidence of post-hanging pulmonary distress in cases of attempted suicidal hanging and predictors of outcome among these patients. DESIGN : Five-year retrospective analysis. SETTING: Tertiary care center in south India. PATIENTS :A total of 335 patients who attempted suicidal hanging, aged above 16 years, were admitted during this period. Thirty-eight of them with pulmonary distress established clinically and with radiological evidence of pulmonary injury post hanging met the inclusion criteria. MEASUREMENTS : Data from ICU records of 5 years, X-rays and laboratory investigations were reviewed. In patients identified to have post-hanging pulmonary distress, the neurological status, chest x-rays, arterial blood gas values and outcome data were collected and analyzed. RESULTS : Eleven percent (n = 38) of the 335 patients admitted following attempted suicidal hanging were diagnosed to have post-hanging pulmonary distress. The overall mortality among post-hanging patients was 5%, which increased to 34.2% (n = 13) in the presence of pulmonary distress (P < or = 0.001). Among the prognostic factors evaluated, a PaO 2 / FiO 2 (P/F) ratio of < 100 at admission predicted a poor outcome (P < or = 0.001). CONCLUSION : Post-hanging pulmonary distress is a relatively common complication of hanging and is associated with increased mortality. P/F ratio from arterial blood gas at admission was the only significant predictor of outcome in this group of patients.

Cranial nerve involvement in patients with leprous neuropathy.

BACKGROUND: Leprosy is one of the most common causes of peripheral neuropathy, perhaps closely matched by diabetic neuropathy. Patterns of peripheral neuropathy in leprosy can be varied, which may include mononeuropathy, mononeuritis multiplex and symmetric polyneuropathy. Cranial nerves, especially facial and trigeminal nerves, are also commonly involved in leprosy. AIMS: To find out the pattern and spectrum of cranial nerve involvement in a consecutive series of patients with leprous neuropathy. SETTINGS AND DESIGN: A retrospective review of patients admitted with leprosy to the Neurology Department of a tertiary care center. MATERIALS AND METHODS: All consecutive patients admitted during an 8-year period (1995-2003) and diagnosed to have leprosy were included. They were clinically evaluated to determine the frequency and pattern of cranial nerve involvement. RESULTS: About 18% (9/51) of the leprosy patients seen during that period had clinical evidence of cranial nerve involvement. Facial and trigeminal nerves were the most commonly affected (five and four patients respectively). CONCLUSIONS: Cranial nerve involvement is common in leprosy, which emphasizes the need to carefully examine them. Also, one should exclude leprosy in patients presenting with isolated cranial neuropathies.
