A Case of Chemical Pneumonitis After Ingestion of Hydrocarbon: Suk Hwan Kim, Yangjin Jegal, Nari Choy, Yangho Kim; Korean Journal of Occupational and Environmental Medicine 2009;21(4):406-411. Published online December 31, 2009; DOI: https://doi.org/10.35371/kjoem.2009.21.4.406

Abstract PDF: BACKGROUND
Hydrocarbon is used frequently in the home in places such as the kitchen, garage, and basement. Accidental ingestion of hydrocarbons occurs generally in infants and children in the home. In cases of accidental ingestion, the amount is usually too small to cause medical problems, but can bring about diseases such as chemical pneumonitis.
CASE
REPORT: After ingesting organic solvent mistaken for mineral water, a 53-year-old male complained of cough, fever, and pain in the right upper abdomen, back, and right chest. Simple chest x-ray revealed focal chemical pneumonitis mainly involving the right middle lobe. The resulting lung abscess did not resolve until after treatment with drainage accompanied with antibiotics therapy. The ingested solution was analyzed and found to be a C11~C13 hydrocarbon mixture which has low viscosity.
CONCLUSION
Chemical pneumonitis occurred after ingestion of hydrocarbon solution, and there is evidence of aspiratory mechanism.

A Case of Cerebellar Dysfunction After Acute Organotin Poisoning: Suk Hwan Kim, Cheol In Yoo, Jee Hyun Kwon, Jin Ho Bae, Young Cheol Weon, Yangho Kim; Korean Journal of Occupational and Environmental Medicine 2009;21(3):289-292. Published online September 30, 2009; DOI: https://doi.org/10.35371/kjoem.2009.21.3.289

BACKGROUND
We performed a follow-up study of an acute organotin poisoning case on the neurological sequelae that remained after 3 years since diagnosis.
CASE
In the previous study, a 43-year-old male was reported for acute organotin poisoning. After 3 years, the neurological sequelae were studied using neurological examination, cognitive tests, neurobehavioral tests (by CAYSYS 2000(TM)), brain magnetic resonance imaging (MRI), and 18F-fluorodeoxyglucose (18F-FDG) PET/CT. Upon neurological examination and other tests, orientation was improved compared to that 3 years before, but cerebellar ataxia, dysmetria and dysdiadochokinesia remained the same, with little change. Brain MRI showed cerebellar atrophy. 18F-FDG PET/CT revealed mildly decreased metabolic activity in the pons and in both cerebellar hemispheres.
DISCUSSION
This is the first brain MRI study on cerebellar atrophy caused by organotin poisoning. Cerebellar ataxia was confirmed by decreased metabolic activity in 18F-FDG PET/CT.

Early Objectified Detection Method of Sensorineural Component in Hand Arm Vibration Syndrome: Jae Kuk Yoon, Hun Lee, Nari Choy, Suk Hwan Kim, Hyoung Ouk Park, Ji Ho Lee, Cheol In Yoo; Korean Journal of Occupational and Environmental Medicine 2009;21(2):143-153. Published online June 30, 2009; DOI: https://doi.org/10.35371/kjoem.2009.21.2.143

Abstract PDF

OBJECTIVES
In order to determine find out the best methods for a more objective detection of neurologic abnormality in early hand arm vibration syndrome(HAVS), early with analyzing the validity of each of the detection methods was analyzed. We evaluated the relationships between the sensorineural stage of Stockholm-revised vibration syndrome classification and the results of several tests.
METHODS
497 workers were investigated for symptom, exposure duration, the types of tools used, and medical history from January 2000 to December 2007. Pain sense threshold, vibrotactile threshold, hand grasp force, finger grasp force, and a finger tapping frequency test were performed by the workers.
RESULTS
The grinder(67.3%) was the most commonly used tool and the mean exposure duration was 14.8 years. Although the pain sense and vibrotactile threshold level tended to increase according to sensorineural stage of the Stockholm classification, there was statistically significant difference in the vibrotactile threshold of 125, 250 Hz (p=0.006~0.038) but not in the pain sense threshold. Hand and finger grasp force tended to decrease according to the sensorineural stage of Stockholm classification and there was statistically significant difference(p=0.041,<0.001, 0.034) only on the right hand side. The tapping frequency also generally decreased according to the sensorineural stage of the Stockholm classification and there was statistically significant difference (p=0.002~0.019) only on the left hand side.
CONCLUSIONS
Although there is no single standardized method that can objectively diagnose the sensorineural component of early HAVS early, the combination of subjective symptoms, the sensorineural stage of Stockholm classification, the pain and vibrotactile threshold test, the hand and finger grasp force, and the finger agility (tapping) test can objectively detect sensorineural component of HAVS early.

A Case of Raynaud's Phenomenon of both Feet in a Rock Drill Operator with Hand-arm Vibration Syndrome: Nari Choy, Chang Sun Sim, Jae Kuk Yoon, Suk Hwan Kim, Hyoung Ook Park, Ji Ho Lee, Cheol In Yoo; Korean Journal of Occupational and Environmental Medicine 2008;20(2):119-126. Published online June 30, 2008; DOI: https://doi.org/10.35371/kjoem.2008.20.2.119

Abstract PDF

BACKGROUND
There have been many studies on hand-arm vibration syndrome (HAVS) for almost a century. The Stockholm Workshop scale has been accepted as a useful tool in diagnosing HAVS. Although they are not standard tests for diagnosis, cold provocation test and plethysmography of the fingers are commonly used as objective measurements to confirm the vascular component of HAVS. However, there are only a handful of case reports and studies worldwide on Raynaud's phenomenon in the toes. We report the case of a patient with HAVS who developed Raynaud's phenomenon in the toes after the vibration exposure had ceased. To our knowledge, this is the first report of this entity in Korea.
CASE
REPORT: A 58-year-old male, who had been diagnosed with HAVS in 2003, first noticed white toes in the summer of 2006 after immersing his feet in cold water. He had been working as a rock drill operator since 1976 for almost 30 years and had symptoms on his fingers since 1992. He underwent the cold provocation test, photoplethysmography, Nerve conduction velocity, and basic laboratory tests to rule out other causes of secondary Raynaud's phenomenon. To describe the severity of his feet, it could be classified as vascular stage 2 and sensorineural stage 1 if we were to apply the Stockholm Workshop scale.
CONCLUSIONS
The patient showed vibration-induced white toes, and we would like to share the results of objective findings related to his condition. When diagnosing HAVS, symptoms of the feet should be assessed by the occupational and environmental medicine physicians. Further studies are needed to standardize test methods to diagnose "vibration-induced white toes."
