Specimen file:Enterobiusvermicularis
A clinical dossier on a single, persistent, low-grade infection in one patient - subject designation H., male, 30s, northern Sweden. What began as a routine parasitological note has been amended, repeatedly, into something closer to a record of a life. The organism is common. The case is not. Findings follow.
The patient presents with a chronic, asymptomatic-by-day infestation of E. vermicularis, complicated by two co-morbid conditions of non-parasitic origin: a phantom haptic disorder traced to a defunct wrist device, and a severe exhaustion syndrome secondary to simultaneous multi-employment. The organism is trivially curable. The patient has declined treatment. The clinical team has, over time, stopped recommending it.
Taxonomic placement of the organism
A standard nematode of the family Oxyuridae, distinguished in this case by a sub-classification the institute has never formally submitted to any registry. The lab simply began, at some point, calling the patient's particular population by his name. No one corrected them.

Anatomical X-ray of the specimen
The blunt anterior. Anchors to the mucosa. Holds on without effort, the way some things simply stay.
A muscular pump. Tireless. It does its one job perfectly, which is more than the patient can say of his five.
Translucent, thread-thin, almost not there. Visible only against the dark, only at the right angle, only when looked for.
The tapered tail. It is the last of the organism to leave the host, and in this patient it never fully does.
Presenting symptoms and co-morbidities
The parasite alone would be unremarkable. What makes the case is the constellation around it - two syndromes the institute has had to coin terms for, because nothing in the literature quite fit a man this tired in a place this dark.
Nocturnal pruritus, perianal
A faint, formless itch arriving after midnight, once the five shifts are finally done. Classic for E. vermicularis. The patient has long since stopped scratching it; he reports it now reads less as irritation than as company keeping its hours.
Phantom haptic hertz vibrations
The patient perceives a recurring tactile buzz at the left wrist - a soft, rhythmic ~180 Hz pulse - in the precise location of a wristwatch he no longer charges. No device is present. The watch is a discontinued Pebble; its charger is lost and irreplaceable. The nervous system continues to receive a notification from a machine that has been dead for years. He looks down every time. There is nothing there every time.
Chronic multi-employment exhaustion syndrome (CMEES)
A whole-body fatigue secondary to holding five simultaneous jobs, none of which accumulate into rest, income, or record. Presents as flattened affect, cold extremities, and a tiredness the patient describes not as a state but as a room he now lives in. No restorative phase observed in the charted period.
Productive anhedonia (the empty grid)
Despite nightly attempts at the keyboard, the patient produces zero committed work. The contribution graph - a clinically useful longitudinal record - shows an unbroken grey field. The lab regards this as the truest chart in the file: a year of intent with nothing planted in it.
Vitals and longitudinal readings
Prognosis and the matter of treatment
The parasitic component is, clinically, nothing: a single dose of antiparasitic, hot laundering, short nails, the whole household at once - resolved within a fortnight. This has been explained to the patient on multiple occasions. He understands it perfectly.
Treatment refused. Documented rationale, transcribed verbatim: to clear the organism, the patient would first have to concede it is there, and it is the only thing that reliably is. The phantom watch cannot be charged. The exhaustion cannot be prescribed against. Of the three findings, the parasite is the only one curable, and so it is the only one he has chosen to keep.
Clinical note, undated, in the margin: "He is not refusing care. He is refusing to be left with nothing."
