Abstract: Neurocutaneous Syndrome (NCS) is a dental toxicity disorder causing various neurological and dermatological symptoms that are often confused by the lay patient as parasitological infections. The cases of 24 randomly selected patients determined to be NCS cases at Parasitology Center, Inc. (PCI) by OMA are presented. Previously reported and additional toxic sealants are reported. The dermatological and neurological symptoms characteristic of NCS were common to all 24 cases. Incubation period varied between a few hours and 19 years. Inaccurate interpretation of NCS symptoms by health care professionals is discussed. Faulty diagnosis undermines the patients physical and mental health and further traumatizes their quality of life especially when they are diagnosed with mental disorders and forced to submit to psychological treatment against their will. Medical professionals need to become more aware of NCS symptoms to properly tend to their patients well being.
Introduction
Neurocutaneous Syndrome (NCS), a newly discovered dental toxicity syndrome (Amin, 2001) is characterized by neurological and dermatological disorders as well as systemic and related dysfunctions. Patients experience, among other symptoms, pin-prick movement sensations and itchy cutaneous lesions that may invite various opportunistic infections. Components of the calcium hydroxide sealants Dycal, Life, and Sealapex, among others, have been identified as the source of the observed symptoms. The toxicity of sealants, compounding factors and case histories were discussed and management protocols practiced at Parasitology Center, Inc. (PCI) were proposed by Amin (2003, 2004). Lay NCS patients often confuse the movement sensations, itchy skin and related symptoms with parasitic infections and seek medical help under this assumption. Invariably, they are diagnosed with and treated for other etiologies often including arthropod infestation and/ or mental conditions such as psychosis. Patients are genuine clinical cases that should not be further compromised by inaccurate diagnosis, wrongly medicated or subjected to psychological treatment in mental health care facilities. On occasions, I spend time helping NCS patients out of mental facilities. The institutionalization of some patients seriously compromise their state of mental and physical health, self confidence, and their ability to make sound decisions.
This paper address the various aspects of diagnosis of NCS patients by MDs, dermatologists and other health care professionals as well as the symptoms and outcome of 24 NCS patients.
Materials and Methods
Files of 24 patients were randomly selected from among those examined at PCI and determined by OMA as NCS cases. Information on patients' dental history, symptoms, interpretation of NCS symptoms by health care professionals, diagnosis at PCI by OMA and outcome were compiled from our files and summarized in Table 1. All patients were personally interviewed and information provided was substantiated with documents, dental histories and personal observations. Dermatological symptoms were invariably documented by photos taken by OMA. Patients pursuing dental rehabilitation were initially referred to a holistic dentist, started off on a prescribed regimen of vitamins and supplements, required to take a biocompatibility blood test for sensitivity to dental material and, more recently, underwent laser and lymph drainage therapy at PCI.

Patients
The NCS patient population clearly includes many more females than
males. The reported random sample of 24 patients included two 42 and 53
years old males (mean 47) and 22 33-79 years old females (mean 45).
Twenty-two patients were from the United States and two from Europe,
Norway & Sweden. The predominance of females among NCS cases is not
fully understood in cases of toxicity disorders. Whether susceptibility
to toxins such as sulfa may be differentially mediated by hormones or
not is unknown.
Dental History
The sealants incriminated in the 24 NCS cases studied (Table 1)
included the zinc oxide/ ethyltoluene sulfonamide sealants Dycal, Life
and Sealapex, among others, previously reported to be toxic (Amin,
2003, 2004). Other dental material including zinc oxide, e.g., Caulk
and Gutta Percha that were not reported by Amin (2003, 2004) were also
involved in new NCS cases reported herein e.g., cases no. 2, 8 and 10.
Most cases seen by me within the last two years were compromised by
dental work using toxic material as early as 1978 (case no. 2) while
others as recent as 2002 (case nos. 10, 19) (Table 1).
Symptoms
The most common dermatological and neurological symptoms of NCS were
observed in all 24 patients. Some of these patients had well documented
sulfa sensitivity. Other systemic difficulties, e.g., respiratory,
intestinal were also noted (Table 1). The time between the original
dental procedure and first appearance of symptoms (incubation period)
varied between a few hours (case no. 5) and 19 years (cases nos. 1
& 20) (Table 1). We have other records of incubation periods of up
to 32 years. Amin (2004) indicated that “the toxicity of ethyltoluene
sulfonamide is determined by the concentration of this compound in the
sealant used, the amount of sealant used and number of teeth involved”
and that “the patient's reaction will depend on the degree of
sensitivity to the compounds. These variables determine the time after
which the patient will begin to experience symptoms.”
Diagnosis Given
Diagnosis given by health care professionals usually involved
arthropods (that are never recovered), and unspecific dermatitis for
which patients were medicated but showed no improvement. What is most
disturbing is diagnosing patients with various mental disorders, e.g.,
psychosis, anxiety disorder, delusional parasitosis or the charging
that the dermatological symptoms were self inflicted. Thirteen patients
(54%) were given diagnosis of mental disorders (Table 1). The ensuing
trauma has driven a few of my patients to the edge, contemplating
suicide. Medical professionals do need to have a better understanding
of NCS as a genuine clinical syndrome and deal with their patients from
that perspective.
Diagnosis at PCI
Most of the reported patients were diagnosed with NCS at PCI by OMA
within the last two years. Those that followed up with our treatment
recommendations (Amin, 2004) had invariably recovered (cases nos. 5,
10, 12, 13, 15, 19, 24). Recovery of a few other patients is partial or
underway; more time is needed. Depending on the toxicity variable
mentioned above (see symptoms), recovery can take anywhere between a
few weeks and up to one year. Fully recovered patients, however, may
retain some sensitivities to mold or humid un-aerated places. Early
stages of healing can become quite painful, e.g., case no. 3 (Table 1).
