1/13. delusions of parasitosis in clients presenting pets for veterinary care.The syndrome delusions of parasitosis (DP) constitutes a psychiatric disorder of humans in which patients falsely believe that they are infested with parasites. This report describes 2 cases of DP observed at the Onderstepoort Veterinary Academic Hospital (OVAH). The first case involved a 34-year old, single female, who believed that she and her three cats were being parasitised by insects of unknown origin. Before referral to the OVAH, she had taken her cats to 2 other veterinarians and had consulted 2 dermatologists herself. The second case was a single male who believed that he was being parasitised by insects originating from his cat. A full diagnostic evaluation performed on all 4 cats failed to reveal any dermatological abnormalities. No parasites were seen or cultured from any of the cats.- - - - - - - - - - ranking = 1keywords = parasitosis (Clic here for more details about this article) |
2/13. Regional cerebral blood flow changes in a patient with delusional parasitosis before and after successful treatment with risperidone: a case report.The pathophysiology and appropriate pharmacological interventions for delusional parasitosis (DP) remain unknown. Here, we present a case of DP following brain infarction of the right temporoparietal region. Pharmacotherapy with risperidone resulted in a dramatic therapeutic response over a short period. In a sequential N-isopropyl-p-[(123)I]-iodoamphetamine single photon emission computed tomography ([(123)I]-IMP SPECT) study, post-treatment SPECT images revealed a marked increase of rCBF in the large areas including the bilateral frontal and left temporoparietal regions, the right parietal operculum and the bilateral basal ganglia, in contrast to pre-treatment SPECT images showing a global decrease of rCBF. Our clinical outcome suggests the efficacy and safety of risperidone for treatment of DP and that both dopaminergic and serotonergic dysfunction may play a role in DP. Our sequential SPECT findings suggest that psychiatric improvement of DP is associated with increased rCBF.- - - - - - - - - - ranking = 3.2324889547822keywords = delusional parasitosis, parasitosis (Clic here for more details about this article) |
3/13. Successful treatment of delusions of parasitosis with olanzapine.BACKGROUND: delusional parasitosis is a rare disorder in which patients have a fixed, false belief of being infested with parasites. It is often accompanied by a refusal to seek psychiatric care. delusions of parasitosis is classically treated with typical antipsychotic agents, the traditional dermatologic choice being pimozide. However, pimozide's adverse effect profile and the need for frequent electrocardiographic monitoring make such treatment less practical. observation: We describe 3 patients who were diagnosed as having delusional parasitosis that was successfully treated with a recently food and Drug Administration-approved atypical antipsychotic agent, olanzapine (5 mg/d). Olanzapine has a more benign adverse effect profile than typical antipsychotic agents and eliminates the need for electrocardiographic monitoring. Olanzapine therapy has been associated with such adverse effects as sedation, hyperlipidemia, weight gain, and insulin resistance, all of which were infrequent in our patients. CONCLUSION: Olanzapine is an atypical antipsychotic agent that can be used as a first-line agent in delusional parasitosis as a safer therapeutic option without a specialized monitoring regimen.- - - - - - - - - - ranking = 2.7162444773911keywords = delusional parasitosis, parasitosis (Clic here for more details about this article) |
4/13. Delusion of oral parasitosis in a patient with major depressive disorder.Delusion of parasitosis is a rare condition in which the patient has a strong conviction that he or she is infested by small organisms. The condition may exist as an isolated phenomenon, or may occur in association with other psychiatric syndromes. We report a single case of a rare form of this phenomenon. A middle-aged woman who met forth edition of diagnostic and statistical manual of mental disorders criteria for major depressive disorder with psychotic features is described. She had delusions of oral parasitosis. She felt lizards and small organisms in her mouth. To the best of our knowledge, there has been only one previous report of delusions of oral parasitosis to date. We discuss the interesting aspects of this case.- - - - - - - - - - ranking = 1.4keywords = parasitosis (Clic here for more details about this article) |
5/13. Acute delusional parasitosis under treatment with ciprofloxacin.ciprofloxacin-induced psychoses have been described in some case reports, occurring sometimes in multi-morbid or personality disordered patients, but also in healthy subjects. We present a case of a 45-year-old man without previous mental disorder, who developed an acute delusional parasitosis after administration of ciprofloxacin. After discontinuation of ciprofloxacin, a complete and sustained remission could be observed within a few days, without the use of any psychopharmacologic medication. Possible modes of action are discussed.- - - - - - - - - - ranking = 3.7906111934777keywords = delusional parasitosis, parasitosis (Clic here for more details about this article) |
6/13. Chronic wounds and delusions of parasitosis in the drug abuser.Plastic surgeons are routinely consulted about the care of difficult or chronic wounds. Most of these wounds have a physiologic basis and are treated according to basic wound-healing principles. patients with factitious wounds are difficult to treat and present diagnostic dilemmas. We present a case and review of the literature of drug-induced delusions of parasitosis to inform plastic surgeons of this important entity and for consideration in the differential diagnosis of chronic wounds.- - - - - - - - - - ranking = 1keywords = parasitosis (Clic here for more details about this article) |
7/13. Delusion of parasitosis: a report of ten cases at Srinagarind Hospital.Ten patients with delusion of parasitosis who attended the psychiatric service at Srinagarind Hospital from August 1st 1981 to May 31st 1988 were analysed and discussed. Males and females were equally affected. Their ages were between early adulthood and late adulthood. Most of them were or had been married and were economically independent. Their symptoms appeared chronic and they tended to refuse psychiatric treatment. The dermatologist and general practitioner from whom the patients are most likely to seek treatment are reasonable to treat these patients. haloperidol, a widely available neuroleptic, seems to relieve the symptom, enabling the patient to live comfortably.- - - - - - - - - - ranking = 1keywords = parasitosis (Clic here for more details about this article) |

10/13. Monosymptomatic hypochondriacal psychosis manifesting as delusions of parasitosis. A description of four cases successfuly treated with pimozide.A recent article in the archives described the severe problems encountered in trying to treat patients with delusions of parasitosis. The present article describes four such cases, which fall into the larger category of monosymptomatic hypochondriacal psychoses, conditions that appear to be related to the paranoid disorders. Evidence is accumulating that such cases may respond very specifically to treatment with pimozide, a relatively new psychotropic medication. This drug keeps the symptoms in remission but does not effect a cure; nevertheless, it may represent a highly important advance in therapy in a condition traditionally regarded as virtually untreatable.- - - - - - - - - - ranking = 1keywords = parasitosis (Clic here for more details about this article) |
