Gloria Ramirez

Summary

A woman was brought into an emergency room, dying of cancer. Within minutes, the staff treating her began to collapse. Twenty-three of the thirty-seven people in that department fell ill. Five were hospitalised. One spent two weeks in intensive care.

The woman died. Her name was Gloria Ramirez. She was thirty-one years old, she had advanced cervical cancer, and she has been known ever since, in the newspapers and on the internet and in the title of more than one documentary, as the Toxic Lady.

The registry files this record under her name. Whatever happened in that room, she was the person it happened to, and she was not a toxin.

What is documented

Her condition. Gloria Ramirez was brought to the emergency department of Riverside General Hospital on 19 February 1994. She had advanced cervical cancer. She was in cardiac arrhythmia, breathing irregularly, and near death.

What the staff observed. Her skin had an oily sheen. There was an unusual odour, variously described as fruity or garlic-like. When blood was drawn, staff reported an ammonia-like smell, and reported seeing pale, manila-coloured particles floating in it.

The collapse. A nurse, Susan Kane, drew the blood and then fainted. Julie Gorchynski, a medical resident, became severely ill: she stopped breathing, had muscle spasms, and was admitted to intensive care for two weeks. A respiratory therapist, Maureen Welch, also fell ill.

In total, twenty-three of the thirty-seven staff in the department reported symptoms. Five were hospitalised.

The emergency department was evacuated.

Her death. Gloria Ramirez was pronounced dead. The cause was recorded as kidney failure related to her cancer.

The autopsy. It was performed by personnel in airtight protective suits.

The Livermore investigation. The Riverside County Coroner asked Lawrence Livermore National Laboratory to investigate. A team led by Patrick Grant produced the leading hypothesis.

Leading explanations

The DMSO chain. Leading, contested, and never demonstrated.

Dimethyl sulfoxide, DMSO, is an industrial solvent. It is also used, unofficially, as a home remedy for pain. It is available, it penetrates skin readily, and it is known for two side effects: it gives the skin an oily sheen, and it produces a garlic-like taste and odour.

Both of those were observed on Gloria Ramirez.

The Livermore hypothesis runs in three steps. DMSO in her body was oxidised to dimethyl sulfone, DMSO2, possibly assisted by the oxygen she was being given. Dimethyl sulfone crystallises at around room temperature, which would account for the particles seen in the blood. And under some conditions, dimethyl sulfone can be further oxidised to dimethyl sulfate, which is a powerful poison: an alkylating agent and a vesicant, capable of producing exactly the symptoms the staff reported.

The problems with it, and they are serious.

No DMSO, dimethyl sulfone or dimethyl sulfate was ever detected in a sample. The samples had degraded, and the body had been embalmed before some of the testing, which is a real evidentiary failure and it is why this can never be closed.

The final oxidation step, from dimethyl sulfone to dimethyl sulfate, is chemically demanding. Whether it could have occurred in a syringe of cooling blood in an emergency room is disputed, and the Livermore team's reconstruction has been challenged by chemists.

And Ramirez's family have consistently rejected the account, and said she was not using DMSO.

Mass psychogenic illness. The alternative, and the county's early position.

The case for it: the symptoms reported were varied and non-specific. They propagated through the department in a way consistent with people seeing other people collapse. Nothing was ever detected in the room, in the air, or in the body.

The case against it, and it is a strong one: Julie Gorchynski developed avascular necrosis, a real, objective, radiologically visible destruction of bone in her knees. Psychogenic illness does not do that.

The counter-argument is that her avascular necrosis was caused by the high-dose steroids used to treat her, which is a known cause of the condition. That is medically plausible, and it is also convenient, and the registry records the dispute rather than settling it.

A chemical present in the hospital. Advanced by the Ramirez family in litigation: that something in the department, unrelated to her, was the source, and that she was blamed for it.

It has never been substantiated. It has also never been excluded, and the family's anger at the framing of the case is entirely intelligible.

Current status

Partially explained. A plausible chemical mechanism exists, was proposed by a national laboratory, is chemically contested, and was never confirmed by a sample, because the samples were not preserved.

The registry keeps this record with two things stated plainly.

The staff of that emergency department were genuinely hurt. So were the family of Gloria Ramirez, who lost a daughter and a mother and then watched her become a monster in the newspapers.

Nobody in that room did anything wrong, and thirty-two years later there is still no answer, and the reason there is no answer is that the evidence was allowed to degrade.
