Abstract

Introduction: Camphor is a highly lipophilic bicyclic monoterpene ketone that acts through transient receptor potential channels 1/2 (TRPV1/TRPA2) and produces local pain relief by desensitizing sensory neurons. We present a case of accidental camphor overdose with associated camphor product concentrations in a patient with previous seizure disorder. 

Case Report: A 53-year-old female (112.49 kg) presented to an urban emergency department (ED) by ambulance after accidental ingestion of an estimated 4 ounces of 6.2% camphor oil humidifier solution (6.2 grams of camphor per 100 mL). After initial examination and anxious, jittery symptoms were reported by the patient, 2 mg of lorazepam was given intravenously in an attempt to raise her seizure threshold. Due to the patient’s history of seizures and the recommendation of the poison control center, the patient was admitted for observation and monitored for seizure activity. 

Discussion: A case of accidental camphor overdose with associated camphor product concentrations is presented. While inpatient, this patient remained asymptomatic with unchanged labs.

Section 2  Scope.

  1. License grant.
    1. Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:
      1. reproduce and Share the Licensed Material, in whole or in part, for NonCommercial purposes only; and
      2. produce and reproduce, but not Share, Adapted Material for NonCommercial purposes only.
    2. Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.
    3. Term. The term of this Public License is specified in Section 6(a).
    4. Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section 2(a)(4) never produces Adapted Material.
    5. Downstream recipients.
      1. Offer from the Licensor  Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.
      2. No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.
    6. No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section 3(a)(1)(A)(i).
  2. Other rights.
    1. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.
    2. Patent and trademark rights are not licensed under this Public License.
    3. To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties, including when the Licensed Material is used other than for NonCommercial purposes.

Section 4  Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

  1. for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only and provided You do not Share Adapted Material;
  2. if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and
  3. You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

Unless otherwise separately undertaken by the Licensor, to the extent possible, the Licensor offers the Licensed Material as-is and as-available, and makes no representations or warranties of any kind concerning the Licensed Material, whether express, implied, statutory, or other.

Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You.
  2.

Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.
  1. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

    1. automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or
    2. upon express reinstatement by the Licensor.

For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.

  1. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.
  2. Sections 1, 5, 6, 7, and 8 survive termination of this Public License.

  2. To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.
