Heat-Related Rash (Miliaria)

SOP Codes: No SOP Available

ADF History

Name: The veteran, Date of Birth: [withheld] Occupation: Avionics Technician, Enlistment Date: 06 September 2003, Discharge Date: 19 Mar 2019.

Occupational History

As an Avionics Technician in the Royal Australian Air Force, the veteran was required to work in hot and humid environmental conditions, particularly at the RAAF base in the the territory. His role required regular outdoor work on aircraft flight lines while wearing protective clothing and equipment. The tropical climate at the RAAF base, combined with the occupational requirement to wear non-breathable protective clothing during aircraft maintenance activities, created ideal conditions for the development of heat-related skin conditions. Avionics technicians are exposed to prolonged periods in hot, humid environments while wearing occlusive clothing systems necessary for safety during aircraft maintenance operations.

History

The veteran an Avionics Technician in the Royal Australian Air Force, developed recurrent heat-related rash (miliaria) during his military service due to working in hot, humid conditions while wearing protective equipment. The condition manifested as skin irritation in areas prone to heat and moisture retention, particularly affecting skin fold areas and regions where clothing created occlusive conditions during outdoor work activities.

Timeline

14 Sep 2015 - Medical Officer notes documented miliaria affecting the right upper arm and right ear, elbow and knee skin folds. This occurred during summer conditions at the RAAF base, where the veteran was required to work outdoors in hot and humid tropical conditions. The presentation was consistent with "heat rash" secondary to occupational exposure to hot, humid environmental conditions while wearing protective clothing during aircraft maintenance duties.
17 Jun 2017 - the veteran presented with a rash affecting his back, axillae, and arms, which he had noticed the previous evening. The rash was described as itchy but not warm to touch with no discharge. He reported a history of similar rash the previous year that had been treated with clotrimazole and fluconazole. Clinical examination revealed a considerable "heat-related rash" on his back, axillae, and inside of his elbow. The veteran worked outside on the flightline for approximately half his shift in hot weather conditions. Combination hydrocortisone and antifungal cream was recommended for symptom relief, with the condition directly attributed to occupational heat exposure.

Symptoms

At the time of presentation in November 2016, the veteran experienced skin irritation and rash formation in multiple skin fold areas including the right upper arm, ear, elbow and knee folds. During the August 2018 presentation, he reported an itchy rash affecting his back, axillae, and arms that had developed overnight. The rash was described as not being warm to touch and without discharge. From the available medical documentation, the symptoms were consistent with heat-induced skin irritation and inflammation secondary to working in hot, humid conditions while wearing protective clothing.

Imaging

No imaging studies were performed for this condition. The diagnosis was made on clinical assessment by medical officers.

1. What is the formal diagnosis of the condition claimed above?

Miliaria (Heat-Related Rash), ICD-10 code L74.3. No DVA SOP is available for this condition.

Miliaria, commonly known as heat rash or prickly heat, is a skin condition that occurs when sweat ducts become blocked and sweat is trapped under the skin. This results in characteristic small bumps, redness, and itching, particularly in areas where clothing is tight or where skin folds create occlusive conditions. Miliaria typically develops in hot, humid environments, especially when individuals wear occlusive clothing or are engaged in activities that promote excessive sweating. The condition is classified into different types based on the depth of sweat duct obstruction, with miliaria rubra being the most common form presenting as red, itchy papules.

2. For each diagnosis identified, please also provide the following dates:

When did the veteran first experience symptoms attributable to this condition? 14 September 2015 - First documented presentation with miliaria affecting multiple skin fold areas [CHART REVIEW].

When did the veteran first present to a health / medical provider for this condition? 14 September 2015 - The veteran presented to Medical Officer for assessment of heat rash affecting right upper arm, ear, elbow and knee skin folds [CHART REVIEW].

When was the condition confirmed / formally diagnosed? 14 September 2015 - The condition was diagnosed by Medical Officer based on clinical presentation and occupational history of heat exposure [CHART REVIEW].

When did the veteran first present to you (or your practice) for this condition? 05 Apr 2021.

3. How was this diagnosis confirmed? i.e. what were the key symptoms and signs, investigation results, specialist opinions? Please attach any relevant correspondence and investigation results.

The diagnosis was confirmed by Medical Officer clinical assessment based on characteristic presentation of heat rash in typical anatomical locations [CHART REVIEW]. The key diagnostic features included the development of rash in skin fold areas (right upper arm, ear, elbow and knee folds) during hot summer conditions at the RAAF base. The temporal relationship between occupational heat exposure and symptom development, combined with the characteristic distribution pattern in areas prone to heat and moisture retention, supported the clinical diagnosis. The recurrent nature of the condition, with similar presentations in 2018 and 2019, further confirmed the occupational relationship to heat exposure during flight line duties.

4. What do you consider to be the cause(s) of the condition in this veteran? Give consideration to constitutional and common risk factors, pre-existing injuries or diseases, and occupational or lifestyle risks, as well as direct causative mechanisms.

No SOP factors apply as there is no DVA Statement of Principles for miliaria. However, the condition is directly related to occupational exposure to hot, humid environmental conditions while wearing protective clothing during aircraft maintenance duties. The veteran was required to work outdoors on the flight line for approximately half of each shift in tropical conditions at the RAAF base. The combination of environmental heat, humidity, and occlusive protective clothing created ideal conditions for sweat duct obstruction and subsequent miliaria development. This represents a direct occupational causation where the requirements of military service created the environmental conditions necessary for disease development.

Sequelae

This condition is not considered a sequelae of another known condition. Miliaria is a primary skin condition related to environmental heat exposure and occlusive clothing requirements.

Unintended Consequence

This condition is not considered an unintended consequence of medical management. No procedures or medications were documented that would have resulted in the development of miliaria.

Inability to Attain Appropriate Medical Management

The condition does not meet the criteria for inability to attain appropriate medical management. The veteran was appropriately assessed by medical officers when symptoms developed, with appropriate topical treatments prescribed. The condition was promptly recognized and managed with suitable therapeutic interventions. There is no evidence of barriers to healthcare access or inappropriate management that would have led to permanent worsening of the condition. The Full Federal Court in Brew v Repatriation Commission (01 May 1996) establishes that "inability" encompasses both objective and subjective barriers to treatment, but in this case, appropriate medical care was provided when symptoms developed.

The % contribution of the causes is 100% and significant.

5. Please provide a Health Summary and a medication / prescribing history.
