Clinical Profile of Tension Type Headache in a Medical College with Special Emphasis on Triggering Factors.

Background and Objectives: Tension type headache is one of the costliest primary headaches which can cause a significant impact on an individual's life. Healthcare professionals are exposed to multiple trigger factors which give rise to an increase in headache frequency, most notable reasons being sleep disturbances, stress and untimely food habits. With this background, we conducted this study of detailed clinical profile and trigger factors among the 2050 subjects (MBBS students: 909, BDS students: 323, nursing students: 268, postgraduates students and staff: 550) in our medical institute. Materials and Methods: Subjects were given questionnaires on headache and were instructed to give the details of their clinical symptoms along with relevant questions on trigger factors. The assessment tools used were the Visual Analogue Scale (VAS) and Migraine Disability Assessment Scale (MIDAS). Results: Out of 2050 subjects, 464 patients suffered from tension type headache. Overall prevalence of tension type headache was 22.6%. Prevalence was higher in females (57.9%) as compared to males (42.1%). Headache experienced by majority of the student population was unilateral (31.4%), pulsating type (51.6%) and of moderate intensity (77.1%). Common associated symptoms were nausea associated with other factors (40%) and photophobia and phonophobia (18.6%). Stress (72.1%) and decreased sleep (49.4%) were the most common triggering factors. Practice of self-medication was reported by 80.2% of subjects. Conclusion: Our study noted a high frequency of trigger factors in medical professionals, the most common triggering factors being stress and disturbed sleep. To our knowledge this is the first large study to evaluate headache and specifically tension type headache among medical professionals.

Essential oil related seizures (EORS): A multi-center prospective study on essential oils and seizures in adults.

OBJECTIVE: Essential oils (EOs) like eucalyptus and camphor have pro-convulsant properties. These EOs are present in many over- the- counter balms and oils. The effect of exposure to these EOs and occurrence of seizure is not systematically studied. The aim of this study was to evaluate the relationship between essential oils and the first episode of seizure and breakthrough seizures in known epileptic patients. METHODS: This was a multi-center prospective study, conducted in four hospitals over four years. Every person presenting with the first episode of seizure or breakthrough seizure was asked about exposure to EOs, mode of exposure, time to onset of a seizure in relationship to exposure, duration of seizure, type of seizure, and antiepileptic drug therapy. RESULTS: During the four-year period there were 55 patients with essential oil-related seizure (EORS). 22(40 %) had essential oil-induced seizures (EOIS) and 33(60 %) had essential oil-provoked seizures (EOPS). The female: male ratio was 1:1.1, the age of the patients ranged from 8 months to 77 years. In the EOIS group, 95 % had generalized tonic-clonic seizures and 5% had focal impaired awareness seizures. In the EOPS group, 42.4 % had focal impaired awareness seizures, 27.3 % generalized tonic-clonic seizures, 15 % focal to bilateral tonic-clonic seizures, and 15 % focal aware motor seizures. EOs implicated were preparations containing eucalyptus and camphor. CONCLUSION: Exposure to essential oils of eucalyptus and camphor is an under-recognized cause of the first and breakthrough seizure. Identifying the true causative factor will prevent unnecessary antiepileptic drug therapy and future recurrence.

Eucalyptus oil inhalation-induced seizure: A novel, underrecognized, preventable cause of acute symptomatic seizure.

Eucalyptus oil (EO) is an essential oil that is widely used across the globe as an over-the-counter remedy for common ailments. EO-induced seizure (EOIS) has not been recognized as an entity, and physicians rarely ask the history of exposure to eucalyptus oil when seeing a patient with first episode of seizure. Here we report 10 cases of EO inhalation-induced seizures seen over the past 2 years in three tertiary care hospitals. Eight patients had GTCS and two had CPS. We aim to raise awareness of seizures induced by exposure to eucalyptus oil.
