Several studies have reported raised levels of psychopathology based on self-rating scales in patients with spasmodic torticollis. Recent publications have also proposed that psychopathology, especially symptoms of depression, might be a reaction to dystonia or constitute a nonspecific reaction pattern. To determine the actual frequency of psychiatric disorders, we evaluated 44 patients with spasmodic torticollis (20 female, 24 male; mean age 43.6 years, SD 10.4) using the standard instrument for psychiatric diagnosis in the DSM-III-R (Structured Clinical Interview Schedule, SCID). The SCID permits retrospective diagnosis for most of the major psychiatric disorders, including the time before onset of dystonia. SCID criteria for at least one psychiatric disorder were fulfilled in 65.9% of patients, including both lifetime and current diagnosis. The most frequent diagnostic categories were panic disorder with or without agoraphobia (29.5%), major depressive disorder (25%), substance abuse (13.6%), and obsessive compulsive disorders (6.8%) were diagnosed less frequently. The patient-recalled onset of psychiatric symptoms preceded onset of torticollis symptoms in 43.2% of those investigated.

During 1999 and 2000, a disease outbreak of West Nile (WN) virus occurred in humans, horses, and wild and zoological birds in the northeastern USA. In our experiments, WN virus infection of young domestic geese (Anser anser domesticus) caused depression, weight loss, torticollis, opisthotonus, and death with accompanying encephalitis and myocarditis. Based on this experimental study and a field outbreak in Israel, WN virus is a disease threat to young goslings and viremia levels are potentially sufficient to infect mosquitoes and transmit WN virus to other animal species.

We present a 15-year-old girl with depression, an obsessive compulsive disorder and conduct disorder, who developed EPS (torticollis, bradykinesia and cogwheel rigidity) while on fluoxetine. No other cause of EPS was present. The patient responded well to benztropine but re-experienced EPS when benztropine was stopped. Fluoxetine and benztropine were used concomitantly for 21.2 months and the patient has been off medication for 2 months without EPS. This case report shows that EPS can and does occur in youth with SSRI. Clinicians should be aware of the SSRIs as a potential causative factor for EPS.

Disturbed body image and negative self-referent cognitions caused by the postural disfigurement of the head are regarded as the main reason for elevated depression scores in spasmodic torticollis (ST), but this factor was never controlled for. We therefore compared 48 patients with ST and 48 patients with alopecia areata (AA) who were matched for age, sex, and body image dissatisfaction. Psychiatric diagnoses were based on a structured psychiatric interview (SCID-I). Results of patients with ST and AA were compared with a matched sample of the representative German population. Odds ratios to develop psychiatric comorbidity for patients with ST compared with patients with AA were significantly increased throughout nearly all assessed DSM-IV categories. Logistic regression analysis showed that (1) depressive coping and (2) belonging to the group of patients with ST correlated with a significantly higher rate of current psychiatric diagnosis. We conclude that high psychiatric comorbidity in ST is unlikely to be a mere consequence of chronic disease and disfigurement.

A purpose of the study was to develop the Stress Tolerance Scale (STS) and to assess its diagnostic efficacy in neurological clinical practice. The theoretical ground for stress tolerance measurement is the concept of personal environmental interaction as a process including phases of the subjective stress event appraisal, active reaction and subjective result appraisal. The STS encompasses the response items of the descriptions of the accomplished and unaccomplished person-environment and self-personal relations that result in stress overcoming or in stress maintenance, respectively. Within each group, the additional variants of the transactions were specified according to their space-temporal characteristics. Data sets from 112 healthy people and 247 patients (60 with chronic tension headache, 72 with chronic low back pain, 51 with myasthenia gravis, 14 with progressive muscular dystrophy, 27 with hereditary polyneuropathy and 23 with torticollis) have been analyzed. The validity and quiantitation of the STS were determined by Rasch analysis and comparison of the results with those of total STS score and subscale scores of the Hospital Anxiety and Depression Scale and Russian brief version of MMPI. All correlations were at a level of significance. A decrease of stress tolerance was found in patients with chronic pain syndromes and torticollis. The results indicate that the STS allows assessing stress tolerance and a structure of person-environment interactions used by a patient. It can be utilized for optimization of short-term psychotherapy of neurological patients.

Fourteen chicks, 7-12 days old, that died or had neurological signs (depression, paralysis, torticollis, incoordination, and rolling) were investigated pathologically and microbiologically. Variably sized foci of malacia were present within the parenchyma of the brain stem (cerebral peduncle, optic lobe, and medulla oblongata) and the cerebral hemisphere. Capillary thrombosis with congestion and hemorrhage was frequently observed within the malacia lesions. Gram-positive cocci were recognized in the blood capillary of malacia lesions. Bacteriologically, Enterococcus durans was isolated from the brain, liver, kidney, lung, and spleen. Detection of gram-positive cocci within the blood vessels in the malacia lesions observed in these cases may more strongly suggest the pathogenic role of E. durans on the malacia lesions in the brain stem and cerebral hemisphere.

Thee different combinations of ketamine hydrochloride were used to induce general anaesthesia for surgical operations (typhlectomy) in 30 adult, single-comb White Leghorn cockerels. They were randomly divided into three groups, each comprising 10 birds. Birds in Group I received xylazine-ketamine combinations at the dose rate of 2 mg xylazine and 10 mg ketamine per kg i.v., whereas birds of Group II received diazepam (2.5 mg/kg i.v.) and 5 min later ketamine (75 mg/kg i.m.). In the Group III, midazolam (2 mg/kg i.m.) and 5 min later ketamine (50 mg/kg i.v.) was administered. The onset of sedation/anaesthesia was shortest (1.60 +/- 0.27 min) in Group I, followed by Group II (8.40 +/- 0.83 min) and Group III (17.10 +/- 1.71 min). Recovery period was shortest in the Group I (65-75 min) followed by Group II (80-85 min) and Group III (92-105 min). Sedation, muscle relaxation and surgical anaesthesia was optimal and excellent in Group I compared with the other two groups. Torticollis, salivation and dyspnoea were observed in Group III. Short-term limb contractions were present in all birds in Groups II and III, up to 20 min of observation. Recovery from anaesthesia was smooth in all three groups. A Surgical procedure (typhlectomy) was performed on all birds. Hypothermia was observed in Group II, whereas heart and respiratory depression was recorded in Group I. Blood sugar level did not vary significantly in any anaesthetic regime. The reduction of haemoglobin was maximum in Group II compared with Groups I and III. Hypoxaemia and hypercapnaea were elevated in all birds in Groups II and III. Blood electrolytes did not vary significantly from the baseline values among the three groups of birds during the period of observation (120 min). The xylazineketamine combination was found to be the best anaesthesia for surgical intervention in chickens.

Sixty-one birds of prey admitted to The Wildlife Center of Virginia (WCV; Waynesboro, Virginia, USA) from June to November 2003 were tested for West Nile virus (WNV) infection. Choanal and/or cloacal swabs were obtained and submitted to Virginia's Division of Consolidated Laboratory Services (Richmond, Virginia, USA) for analysis with real-time reverse transcriptase polymerase chain reaction (RT-PCR). Forty birds of prey were positive for WNV by RT-PCR. Five avian families and nine species of raptors were represented, with great horned owls (Bubo virginianus) and red-tailed hawks (Buteo jamaicensis) most frequently affected. Presenting clinical signs were consistent with previous reports of WNV infection in raptors; however, these differed between species. Of WNV positive birds, nonspecific signs of illness were the most common clinical findings, particularly in red-tailed hawks; signs included dehydration (n = 20), emaciation (n = 18), and depression (n = 15). Neurologic abnormalities were frequently identified, especially in great horned owls, and included head tremors (n = 17), ataxia (n = 13), head incoordination (n = 7), torticollis (n = 3), nystagmus (n = 3), and head tilt (n = 3). Great horned owls exhibited anemia and leukocytosis with heterophilia, eosinophilia, and monocytosis consistent with chronic inflammation. Red-tailed hawks were anemic with a heterophilic leukocytosis and regenerative left shift. The majority of WNV cases occurred during August and September; there was a marked increase in the number of raptors admitted to WCV during these months followed by a marked decrease during October, November, and December. This pattern differed from mean monthly admissions during the previous 10 years and suggests a negative impact on local raptor populations. The effects of WNV on avian populations are largely unknown; however, because of their ecological importance, further investigation of the effects of WNV on raptor populations is warranted.

Primary cervical dystonia is typically an adult onset condition with symptom onset usually in the fifth and sixth decade. Young onset (<28 years) is uncommon. We report 76 patients with cervical dystonia as a presenting or predominant feature, with disease onset before the age of 28. Male to female ratio was 1.24:1 and the mean onset age was 21 (3-28) years. A family history of tremor and/or dystonia was noted in 26.3%. Depression and anxiety attacks were present in 23.7%. Prior injury or surgery involving the neck was noted in 17.1%. 23 (30.3%) experienced spontaneous partial or complete remissions within the first 5 years of onset, but all relapsed. Cervical dystonia was predominantly rotational torticollis. 30% developed extra-nuchal dystonia and tremor affecting contiguous parts but in only one there was spread to affect the legs. All 15 patients tested for the DYT1 gene were negative. 74% responded favorably to botulinum toxin injections, whereas none of the 13 patients treated with L-Dopa preparations had a beneficial response. The distinctive features of this entity are discussed.

The ongoing H5N1 Asian epidemic is currently affecting a number of avian species including ducks. These birds are an important part of the poultry industry in the affected countries, and it is likely that they are acting as a reservoir of infection. Ten Pekin ducks were challenged with 100 microl containing 10(7) 50% egg infective dose of the highly pathogenic avian influenza virus (HPAIV) A/Duck/Vietnam/12/05 (H5N1), administered by an intra-nasal and oral route. Clinical symptoms were recorded twice a day up to 14 days postinfection (dpi). Clinical signs were first noted at 2 dpi, with conjunctivitis and slight depression, and progressed over a period of 1-3 days to severe neurologic signs consisting of torticollis, incoordination, tremors, and seizures. Survival times varied from 3 to 7 dpi. On postmortem examination, hemorrhages were observed in the duodenum, ceca, proventriculus, ventriculus, trachea, pancreas, and brain. Histologic lesions, as well as immunohistochemistry positivity, were recorded in the pancreas and brain. In situ hybridization revealed viral antigen associated with acinar pancreatic cells, bronchial epithelial cells, and with cells of the central nervous system as well as neurons of the submucosal plexus of the duodenum. Our experimental findings agree with those previously observed in ducks naturally infected with HPAIV H5N1 viruses, confirming the acquired viral neurotropism and pancreatotropism, as previously noted in other avian species, as well as in humans.
