Concentration of organochlorine in egg yolk and reproductive success of Egretta garzetta (Linnaeus, 1758) at Wat Tan-en non-hunting area, Phra Nakhorn Si Ayuthaya Province, Thailand.

Contaminant analyses in animal eggs have illustrated the benefit of wildlife as indicators of xenobiotic contamination in natural habitats. In 2002, concentrations of 16 organochlorine insecticides were measured in egg yolk and the reproductive success of the little egret, Egretta garzetta, was studied in a population at Wat Tan-en non-hunting area Bang Pahan District, Phra Nakhorn Si Ayuthaya Province, Thailand. Only 4,4'-dichloro diphenylethane (4,4'-DDE) was detected in the yolk of all samples (n=12) at the concentrations ranging from 33.4 to 116.0 ng/gwetwt. Mean eggshell thickness (n=24) was 0.261+/-0.005 mm. Relationships between the concentrations of 4,4'-DDE and eggshell thickness as well as the reproductive success at all stages were not found (P>0.05). Rather, major factors potentially influencing the decline of reproductive success observed during the field study may include strong wind, predators, intraspecific and interspecific competitions.

Lead shot from hunting as a source of lead in human blood.

This study investigates the relationship between the intake of birds hunted with lead shot and the lead concentration in human blood. Fifty adult men from Nuuk, Greenland took part in the study. From September 2003 to June 2004 they regularly gave blood samples and recorded how many birds they ate. We found a clear relationship between the number of bird meals and blood lead and also a clear seasonal variation. The concentration was highest in mid-winter when bird consumption is at its highest. Blood lead was low (15 microg/L, mean concentration) among the participants reporting not eating birds. Among those reporting to eat birds regularly, blood lead was significantly higher, up to 128 microg/L (mean concentration). Concentrations depended on the frequency of bird meals: the more the bird meals, the higher the resulting blood lead. This clear relationship points to lead shot as the dominating lead source to people in Greenland.

Tradeable hunting obligations--a new approach to regulating red deer numbers in the Scottish Highlands?

The population of red deer (Cervus elaphus) in Scotland has doubled over the last 30 years and there is increasing concern among conservationists about the long-term impact of increased grazing on native woodlands and other sensitive nature conservation sites. Currently, the government relies on a voluntary approach to deer control, but landowners seem unable or unwilling to shoot sufficient numbers to meet cull targets. The aim of this paper is to examine alternatives to the 'voluntary approach' supported by insights from a mail questionnaire of landowners and recreational hunters. In principle, subsidies or taxation is possible but the Deer Commission for Scotland, the government agency responsible, has neither the necessary funding or the legislative power to introduce such a scheme. A tradable culling 'obligations' system on the other hand would build on the voluntary principle by allowing individual landowners to 'trade' culling obligations to neighbouring estates. Compared to traditional regulatory approaches, they are less bureaucratic and inefficient and have the potential to meet environmental targets at least cost as landowners can trade their culling obligation to another estate or hunting club should they wish to do so. Overall, the State's role would be restricted to setting the annual cull and the administration of the permit system for which a small charge could be levied per deer.

Acyclovir responsive brain stem disease after the Ramsay Hunt syndrome.

We report an immunocompetent patient with the Ramsay Hunt syndrome (RHS) followed days later by brainstem disease. Extensive virological studies proved that varicella zoster virus (VZV) was the causative agent. Treatment with intravenous acyclovir resulted in prompt resolution of all neurological deficits except peripheral facial palsy. This case demonstrates that after geniculate zoster, brainstem disease may develop even in an immunocompetent individual and effective antiviral therapy can be curative.

Adolescent respiratory symptoms--girls are at risk: the Young-HUNT study, Norway.

The objective was to study sex differences in adolescence regarding prevalence of asthma and current wheeze and to explore the association between respiratory symptoms and hereditary, lifestyle and socioeconomic factors. Young-HUNT included data comprehensive questionnaire on health, disease, lifestyle and social factors from 8817 teenagers 13-19 years conducted in 1995/97 (89% response rate). Questionnaire on respiratory symptoms was based on the International Study of Asthma and Allergy in Childhood (ISAAC). In age groups 13-16 and 17-19 years, current wheeze was reported by 29.0% and 33.5% among girls and 20.4% and 22.1% among boys, whilst the corresponding figures for asthma were 8.5% and 12.2% among girls and 7.1% and 7.0% among boys. Both wheeze and asthma were significantly more prevalent and increased with age in girls compared to boys. Heredity was associated with asthma, but the association was strongest between parents and children of the same sex. Environmental smoking was associated with asthma and wheeze in girls only. Girls reported more asthma and wheeze in association with overweight compared to boys. Girls reported more wheeze and asthma than boys and seemed more susceptible to risk factors such as environmental smoking and overweight than boys. Moreover, girls with mothers having asthma were more likely to be diagnosed as asthmatics themselves.

Ramsay-Hunt syndrome with vesicular stomatitis in a 4-year-old infant.

Ramsay-Hunt syndrome (RHS) usually affects adults, but rare cases of preschool children with RHS have been reported. We report a case of RHS in a healthy 4-year-old girl. At the age of 4 years and 5 months, she complained of pain in her mouth and herpes zoster vesicles were noted on the left soft palate and tongue without left pinna, and complete left facial paralysis subsequently developed. She was treated with acyclovir and steroids. Six months later, her facial paralysis had almost fully resolved.

Management outcome for ruptured anterior circulation aneurysms with a Hunt and Hess clinical grade of III in patients in the 9th decade of life.

BACKGROUND: This study was conducted to define general guidelines for rational clinical decision-making with respect to patients older than 80 years who present with ruptured anterior circulation aneurysms and a Hunt and Hess clinical grade of III. METHODS: The 29 consecutive patients enrolled in this study were treated at 4 participating centers between 1995 and 1998. All were 80 years or older on admission and met 7 eligibility criteria. The decision to treat surgically or non-surgically was made individually at each center. The outcome at discharge was assessed using the Glasgow Outcome Scale (GOS); the Barthel Score (BS) was used to determine the patients' quality of life after discharge. RESULTS: Of 15 surgically treated patients, 4 died before discharge and 8 were discharged in poor condition. Of these, 7 died of unrelated causes within 2 years of the SAH and one is living in a nursing home. Three patients with middle cerebral artery (MCA) aneurysms made a good recovery; they are currently living at home. Of the 14 conservatively treated patients, 10 died during their hospital stay mainly because of rebleeding that occurred within 3 weeks of the subarachnoid hemorrhage (SAH). Three others who were discharged in poor condition died of systemic illness within 2 years. The remaining patient is living in a nursing home with a BS value of 0. CONCLUSIONS: The outcomes for patients treated conservatively were catastrophic. Even in surgically treated patients, favorable outcomes were rare; the best results were achieved in surgically treated patients with MCA aneurysms.

Epithelioid angiosarcoma of the orbit presenting as Tolosa-Hunt syndrome. A clinicopathologic case report with review of the literature.

The clinical diagnosis of Tolosa-Hunt syndrome was first considered in a 66-year-old man with facial pain and diplopia. A complete neuroradiologic evaluation as well as an oncologic work-up yielded normal results. Several courses of oral prednisone provided no significant benefit. Within a year the patient became clinically worse and a CT scan disclosed an abnormal area of enhancement at the left orbital apex. An orbital exploration was performed elsewhere and a histologic diagnosis of myositis was obtained. Because of further worsening the patient was re-evaluated 3 months later and a CT scan showed a mass in the left orbital apex and superior orbital fissure. A second orbital exploration was performed and a sausage-shaped mass encompassing the optic nerve was excised. By light microscopy a poorly differentiated malignant tumor was infiltrating the orbital tissues with areas of intra- and perineural invasion. The tumor cells were arranged in strands and tubules with a definite tendency to form lumens that often contained red blood cells. Electron microscopic studies disclosed features consistent with a neoplasm of endothelial cell origin displaying a polarized basal lamina and rare micropinocytotic vesicles on the luminal side. The presence of multiple, slender microvilli and sometimes tonofilaments as well as desmosomes were interpreted as epithelioid metaplasia of an angiosarcoma.

Meningioma presenting as Tolosa-Hunt syndrome.

A 23-year-old woman was admitted with headache, nausea, vomiting and blurred vision on the left side. Neurological examination showed ptosis with a complete internal and external ophthalmoplegia and a red fullness around the left orbita. Computed tomographic scanning of the brain revealed no abnormalities. As she improved on high doses of steroids a diagnosis of Tolosa-Hunt syndrome (THS) seemed to be indicated. However, magnetic resonance imaging (MRI) showed a lesion with intermediate signal intensity in the left cavernous sinus. Craniotomy was performed when symptoms of THS recurred. Histopathological examination revealed a meningioma with a papillary aspect and some mitoses. This case illustrates that: (1) THS is still a diagnosis by exclusion; (2) MRI and histopathological examination are important if there is any doubt about the diagnosis; and (3) also when there is no doubt, improvement after steroid therapy may be a diagnostic pitfall. Therefore, not only MRI but also orbital phlebography and angiography should seriously be considered.

Vestibular-evoked myogenic potentials in two patients with Ramsay Hunt syndrome.

We report on the function of the inferior vestibular nerve, as monitored by the vestibular-evoked myogenic potentials (VEMP), in two patients suffering from Ramsay Hunt syndrome. Both the patients presented canal paresis (CP) and hearing loss, but in one patient normal VEMP was recorded while the other presented vagus nerve paralysis plus no VEMP response at the highest stimulus intensity used in our institute (i.e., 105 dB nHL).

Steroid-responsive painful ophthalmoplegia in childhood: sphenoid sinusitis presenting as Tolosa-Hunt syndrome.

A childhood case of painful ophthalmoplegia which responded well to steroids was described. Although the clinical features suggested Tolosa-Hunt syndrome (THS), serial magnetic resonance imagings (MRI) revealed ethmoid and sphenoid sinusitis in this 7-year-old boy. It was considered that multiple factors such as allergy, viral infection and swimming predisposed him to develop severe sinusitis and gave rise to his painful ophthalmoplegia.

Cranial polyneuropathy--Ramsay Hunt's syndrome: case report and discussion.

Ramsay Hunt's syndrome is an infectious cranial polyneuropathy caused by varicella zoster, the herpetic virus that also causes chickenpox and shingles. Its symptoms include facial paralysis, ear pain, and an auricular rash. Oral lesions are also present in most cases. This syndrome can affect any cranial nerve and usually affects multiple nerves, causing central, cervical, and peripheral effects. This article reports the case of a 35-year-old white female who was treated by the oral surgery service of a large urban hospital, after first reporting to the emergency clinic. Her reported symptoms of unilateral left-side facial paralysis, auricular pain, and trigeminal hyperesthesia were confirmed by clinical examination. An initial short low-dose steroid regimen was unsuccessful. A second daily dosage of 50 mg of prednisone was successful in 21 days. No permanent sequelae were evident or reported after treatment.

Prevalence of microfilaraemia in episodic weakness and clinically normal dogs belonging to hunting breeds.

Blood samples from 50 dogs with episodic weakness and 50 clinically normal dogs, all belonging to hunting breeds, were examined for microfilariae using the modified Knott's method. The prevalence of microfilaraemia in dogs belonging to the episodic weakness group was 10% for Dirofilaria immitis, 30% for Dirofilaria repens and 8% for Acanthocheilonema reconditum. In the clinically normal group, the figures were 14% for Dirofilaria repens and 4% for Acanthocheilonema reconditum. The overall percentage of dogs with microfilaremia in the episodic weakness group was 44 and that of the clinically normal group 16, with a statistically significant difference (P < 0.01). The prevalence of microfilaremia due to the nonpathogenic filarial species (Dirofilaria repens, Acanthocheilonema reconditum) was 34% and 16% for the episodic weakness group and the clinically normal dogs, respectively, with no significant difference.

Early diagnosis and treatment of Ramsay Hunt syndrome: the role of magnetic resonance imaging.

We present the case of a 47-year-old woman with left otalgia, rotatory vertigo, sensorineural hearing loss and acute facial nerve palsy. An enhanced magnetic resonance imaging (MRI) scan showed discrete enhancement of the facial and vestibulocochlear nerves in the left internal auditory canal as well as of the labyrinth. This appearance was compatible with that in Ramsay Hunt syndrome and acyclovir was started prior to the appearance of any vesicular eruption. The diagnosis was subsequently confirmed serologically. She regained full facial function but the sensorineural hearing loss persisted. The literature pertaining to the role of the MRI in acute facial palsies is reviewed.

An extreme and unusual variant of Ramsay Hunt syndrome.

Ramsay Hunt syndrome is characterized by facial nerve paralysis, herpetic vesicles in or around the ear and pain often associated with vestibulocochlear nerve involvement. It is thought to be a cranial polyneuropathy caused by the herpes zoster virus. We present an extreme and unusual variant of this disease with involvement of VIIth, VIIIth, Xth, XIth and XIIth cranial nerves as well as C2-4 sensory dermatomes and profound systemic upset which caused some diagnostic uncertainty.
