Epileptic phenomena are usually not considered a possible cause of prolonged hallucinatory states such as Charles Bonnet syndrome (CBS). A 65-year-old woman with previous right hemorrhagic strokes developed complex visual hallucinations (CVHs), featuring CBS, and delayed palinopsic phenomena, along
The antiprogestin ZK 98.299 (11 beta-(4-dimethylaminophenyl)-17 alpha-hydroxy-17 beta-(3-hydroxypropyl)-13 alpha-methyl-4,9-gonadien-3-one) was administered s.c. (30mg/day) to two groups of cycling bonnet monkeys. In Group I (n = 6), it was injected from day 16 to 18 and in Group II (n = 9) from day
BACKGROUND
Craniosynostosis is the premature fusion of one or more of the cranial sutures and can occur as part of a syndrome or as an isolated defect. Pansynostosis is a rare form of craniosynostosis that involves premature fusion of all the cranial sutures (coronal, sagittal, metopic, and
Bioabsorbable implants prepared by fusion of 85% norethisterone (NET) and 15% cholesterol were inserted subdermally in four cycling bonnet monkeys (Macaca radiata). No skin reaction or inflammation was observed at the site of implantation. Plasma concentration of norethisterone (NET) measured by
Ultrasound is a powerful, low-cost, non-invasive medical tool used by laboratory animal veterinarians for diagnostic imaging. Sonohysterography and transvaginal ultrasound are frequently used to assess uterine anomalies in women presenting with abnormal uterine bleeding (AUB). In the present study,
The congenital retinocephalic facial vascular malformation syndrome is characterized by unilateral, nonhereditary retinal and cerebral arteriovenous malformations (AVMs) and is occasionally associated with orbital vascular changes. Typical signs are facial and oral mucosal vascular changes, rarely
The antiprogestin ZK 98.299 (onapristone) was injected subcutaneously (25 mg/day) for 4 consecutive days during early pregnancy to 8 bonnet monkeys. Retrospective analysis of the data showed that the treatment was initiated between 20 to 30 days after the mid-cycle peak in estradiol levels. In 7
BACKGROUND
A 10-year-old, female bonnet monkey (Macaca radiata) showed abnormal menstrual cycle length with heavy menstrual bleeding for 6-8 days.
METHODS
Uterine ultrasound and histological examinations of endometrium by endometrial biopsy.
RESULTS
An ultrasound examination of the uterine cavity
The effects of an antiprogestin ZK 98.299 (onapristone) on serum levels of estradiol and progesterone, and on the endometrial morphology were studied in adult bonnet monkeys. Twelve animals having menstrual cycles of normal duration (24 to 30 days) were randomly distributed into 4 equal groups. The
We reported a patient who suffered from complex visual hallucinations with left homonymous hemianopsia. Brain imaging showed an acute haemorrhage infarct at the right occipital lobe. Charles Bonnet syndrome (CBS) was suspected and aripiprazole was prescribed at 5 mg daily. After 3 weeks, the
CONCLUSIONS
The diagnosis of Bonnet-Dechaume-Blanc or Wyburn-Mason syndrome encompasses a spectrum of phenotypic expression. Features of the syndrome as originally described, and common to all, include arteriovenous malformations of the brain and orbit (with retinal and/or retrobulbar lesions). A
Dengue virus (DENV) causes a wide range of illnesses in humans, including dengue fever and dengue haemorrhagic fever. Current animal models of DENV infection are limited for understanding infectious diseases in humans. Bonnet monkeys (Macaca radiata), a type of Old World monkey, have been used to
A patient with a history of Parkinson's disease and severe bilateral peripheral vision loss due to vitreous hemorrhages had complex visual hallucinations that persisted for three days and appeared every morning on awakening. The persistent nature of these hallucinations, the patient's preserved
