The tranquillising activity of 3-[gamma-(p-fluorobenzoyl)propyl]-2,3,4,4a,5,6-hexahydro-1-(H)-pyrazino [1, 2-a]quinoline hydrochloride (centpyraquin), a new adrenergic neurone blocking antihypertensive agent, has been evaluated in various laboratory animals. The compound has a calming effect in mice, rats, cats and monkeys. In low doses it reduces the spontaneous motor activity followed in progressively higher doses by hypothermia, ptosis and catalepsy and a taming effect in monkeys and cats. It potentiates pentobarbitone-, hexobarbitone- and ethanol-induced sleep and antagonises amphetamine induced toxicity in mice. It, however, fails to antagonise morphine induced mania and hyperactivity in cats. It blocks conditioned avoidance response in rats at a much lower dose (ED50 = 2.73 mg/kg) than the unconditioned response (ED50 = 10,9 mg/kg). In cats centpyraquin increases the voltage and slows the frequency of cortical EEG discharges. Centpyraquin has the profile of activity of a neuroleptic on the central nervous system.

Alcohol is the most frequent and most important teratogenic agent causing mental and physical retardation in childhood. The alcohol fetal syndrome is characterized by pre- and postnatal growth retardation, hypotonia, hyperactivity, microcephalus, mental retardation and typical craniofacial malformations. The latter includes short palpebral fissures, a poorly developed philtrum, thin upper lip vermillion, short mandibles, a flattened midface structure and dysplastic ears. Ophthalmological signs occur in 90% and include epicanthus, ptosis, myopia, optic nerve hypoplasia and tortuous retinal vessels. Microphthalmus, coloboma and Peters' anomaly have also been described. Five children with alcohol embryopathy are presented. The histopathological findings of the enucleated eye of a 6th child with alcohol embryopathy which was sent to us for examination and which revealed an anterior staphyloma with Peters' anomaly is also described. Ophthalmologists should be aware of alcohol in pregnancy as a preventable cause of eye malformation.

The potential antidepressant effect of flerobuterol (dl-(fluoro-2 phenyl)-1 t-butylamino-2 ethanol), a new drug related to beta-adrenoceptor agonists, was evaluated and compared with imipramine and salbutamol using classical psychopharmacological tests in mice. Like imipramine and salbutamol, flerobuterol (0.5-32 mg kg-1, ip) fully prevented apomorphine (16 mg kg-1, sc)- and partly reversed reserpine- and oxotremorine-induced hypothermia. At higher doses (16-32 mg kg-1), flerobuterol enhanced the toxic effects of yohimbine. Unlike imipramine, flerobuterol and salbutamol did not reduce immobility duration in the behavioural despair test. Salbutamol and flerobuterol decreased locomotor activity. Flerobuterol did not induce mydriasis, did not prevent oxotremorine-induced tremors or salivary and lacrimal gland secretion and did not reduce reserpine-induced palpebral ptosis. Propranolol (8 mg kg-1, ip) but not alpha-methyl-paratyrosine (75 mg kg-1, ip) prevented the flerobuterol-induced antagonism of apomorphine-induced hypothermia. Our results suggest that flerobuterol demonstrates potential antidepressant activity, which could be related to beta-adrenoceptor activation in mice.

A series of substituted 4-aryltetrahydrothieno[2,3-c]pyridines was prepared by acid-catalyzed cyclization of 1-aryl-2-[(2-thienylmethyl)amino]ethanol derivatives. The compounds were examined for their antidepressant activity, as demonstrated by their ability to inhibit the uptake of norepinephrine (NE) and serotonin (5-HT) and to prevent tetrabenazine-induced ptosis (TBZ) in mice. Significant inhibition of both neurotransmitters is observed for several of the tested compounds, while some of them are selective inhibitors of either NE or 5-HT uptake. Optimal activity is associated with the introduction of lipophilic substituents into the 4-position of the phenyl ring and less lipophilic substituents into the 2-position of the thiophene ring (11, 23). Compound 33 bearing substituents in positions 2 and 6 of the phenyl ring is inactive. This might be a consequence of an out of plane conformation of this compound.

A great number of the anxiolytics used in the clinical practice are structurally 1,4-benzodiazepines. Tofisopam is the first derivative which differs from the so-called classical benzodiazepines in the position of the nitrogen atoms i.e. in the case of tofisopam they are vicinals (2.3-). This difference in its structure is suspected to be responsible for the different pharmacological and clinical profile of tofisopam. In addition to the anxiolytic activity, sedative, muscle relaxant and anticonvulsive effects are the main characteristics of the most frequently used representative of 1,4-benzodiazepines, diazepam. In contrast, to the above mentioned, tofisopam produces sedation only in higher doses, and does not possess anticonvulsive and appreciable muscle relaxant effects. Tofisopam does not induce sleep even in subtoxic doses, and only high doses enhance the effect of barbiturates and ethanol. Applying doses above 200 mg/kg, tofisopam exhibits effects similar to that of neuroleptics (e.g. catalepsy, ptosis, decrease of pentetrazol threshold, potentiation of amphetamine and apomorphine stereotypy). After repeated administration tolerance to the drug was not observed. Tofisopam does not bind in the CNS neither to the 1,4-benzodiazepine, nor to the GABA receptors, but it enhances the binding of benzodiazepines and muscimol to their binding sites. Tofisopam has also mixed dopamine agonist and antagonist like properties.

It is hypothesized that although the overall metabolism of ethanol in the brain is very limited, a very small percentage of the brain tissue may carry out that little amount of metabolism. Specifically, hydrogen peroxide may be used as a co-substrate for the metabolism of ethanol to acetaldehyde by catalase and the action of monoamine oxidase in the monoaminergic neurons would supply the hydrogen peroxide. This production of acetaldehyde may result in the formation of novel metabolites that provide the rewarding stimulus for the consumption of ethanol. To test this hypothesis, a reversible inhibitor of the A-isoform of monoamine oxidase, BW A616U, was compared to irreversible inhibitors of one or both MAO-A and B isoenzymes. Doses of 12.5-75 mg/kg p.o. BW A616U reduced the behavioral effects, ptosis and catalepsy, due to monoamine depletion by 2.5 mg/kg reserpine, but these signs of monoamine depletion were evident 24 h after injection. In the cyanamide-induced drinking rat, 50 mg/kg BW A616U reduced consumption of ethanol by 37%. Phenylzine, an irreversible MAO-A and B inhibitor, reduced consumption of ethanol by 67%, but also food consumption; however, the intake of both increased during the post-treatment period. The MAO-B inhibitor, R(-)-deprenyl, was without effect. Both BW A616U, 50 mg/kg and 75 mg/kg, and 2.0 mg/kg i.p. clorgyline reduced the consumption of ethanol in the genetic drinking Myers high-ethanol preferring (mHEP) rat and reduced the proportion of ethanol consumed to total fluids by over 50%. Again, R(-)-deprenyl was without effect. Clorgyline also markedly reduced the intake of food during the 3-day treatment period, only. However, the consumption of ethanol remained depressed during the 4 days after either 75 mg/kg BW A616U or clorgyline. These data demonstrate that inhibition of MAO-A, but not MAO-B, reduces the volitional consumption of ethanol probably by preventing the formation of both biogenic aldehydes and acetaldehyde so that rewarding alkaloidal products cannot be formed.

Parasitic infestations, mainly enterobiasis and amoebiasis, and poor toilet training practices are commonly associated with rectal prolapse in developing countries. Injection sclerotherapy is one of the commonly used modalities for treating partial rectal prolapse in children. Various materials are available for such injection, but each has its advantages and complications. Comparing different materials used in the treatment of such pathology form the basis of this study trying to define the best material with the least complications. Data records of 130 children with partial rectal prolapse referred to the Department of Pediatric Surgery at Al Galaa Teaching Hospital, Cairo, over a 3-year period were analyzed. Their ages ranged from 6 months to 12 years (mean 6.14 years +/-3.4). Forty-five patients (3 5%) responded to conservative treatment, and 85 patients (65%) required injection sclerotherapy and were divided into three groups: Group 1 (35 patients) was injected with 98% ethyl alcohol, group 2 (22 patients) was injected with phenol in almond oil 5%, and group 3 (28 patients) was injected with Deflux (Q-Med, Uppsala, Sweden). The follow-up period ranged from 2 months to 3 years; clinical data and all complications were recorded. Submucosal injection of the three sclerosing materials showed no mortality in this series, but in group 1, seven had recurrence on short-term follow-up that required reinjection, and long-term follow-up in this group showed a recurrence rate of 11% (four patients), plus two patients had mucosal sloughing and one girl developed a rectovaginal fistula. Group 2 showed abscess formation and mucosal sloughing in four patients (18%), and two developed perianal fistula. Group 3 showed immediate postoperative prolapse in two cases that ameliorated spontaneously. No patients had mucosal ulceration or abscess formation, and long-term follow-up showed no recurrence. Deflux had the lowest complication rate with no recurrence on long-term follow-up. Phenol in almond oil 5% injection should not be used for treating such conditions because of its high complication rate. Alcohol is commercially cheap and available and should be considered an alternative for Deflux.

The present study investigated the antidepressant effect of ethanol extract of Paeonia lactiflora (EPL) in mice using forced swim test, tail suspension test, open-field test and reserpine test. Our results showed that intragastric administration of EPL at the doses of 250 and 500 mg/kg for seven days significantly reduced the duration of immobility in both forced swim test and tail suspension test. EPL at the dose of 500 mg/kg was as effective as the positive control (chlorimipramine, 20 mg/kg) in these tests. However, these treatments did not affect the number of crossing and rearing in the open-field test. Treating mice with EPL at the doses of 250 and 500 mg/kg significantly antagonized reserpine-induced ptosis and hypothermia. However, at the dose of 125 mg/kg, EPL antagonized only the hypothermia but not ptosis induced by reserpine. The results clearly demonstrated the antidepressant effect of Paeonia lactiflora in animal models of depression. The action of Paeonia lactiflora may be mediated via the central monoaminergic neurotransmitter system.

Cluster headache (CH) is a primary headache disease characterized by recurrent short-lasting attacks (15 to 180 minutes) of excruciating unilateral periorbital pain accompanied by ipsilateral autonomic signs (lacrimation, nasal congestion, ptosis, miosis, lid edema, redness of the eye). It affects young adults, predominantly males. Prevalence is estimated at 0.5-1.0/1,000. CH has a circannual and circadian periodicity, attacks being clustered (hence the name) in bouts that can occur during specific months of the year. Alcohol is the only dietary trigger of CH, strong odors (mainly solvents and cigarette smoke) and napping may also trigger CH attacks. During bouts, attacks may happen at precise hours, especially during the night. During the attacks, patients tend to be restless. CH may be episodic or chronic, depending on the presence of remission periods. CH is associated with trigeminovascular activation and neuroendocrine and vegetative disturbances, however, the precise cautive mechanisms remain unknown. Involvement of the hypothalamus (a structure regulating endocrine function and sleep-wake rhythms) has been confirmed, explaining, at least in part, the cyclic aspects of CH. The disease is familial in about 10% of cases. Genetic factors play a role in CH susceptibility, and a causative role has been suggested for the hypocretin receptor gene. Diagnosis is clinical. Differential diagnoses include other primary headache diseases such as migraine, paroxysmal hemicrania and SUNCT syndrome. At present, there is no curative treatment. There are efficient treatments to shorten the painful attacks (acute treatments) and to reduce the number of daily attacks (prophylactic treatments). Acute treatment is based on subcutaneous administration of sumatriptan and high-flow oxygen. Verapamil, lithium, methysergide, prednisone, greater occipital nerve blocks and topiramate may be used for prophylaxis. In refractory cases, deep-brain stimulation of the hypothalamus and greater occipital nerve stimulators have been tried in experimental settings. The disease course over a lifetime is unpredictable. Some patients have only one period of attacks, while in others the disease evolves from episodic to chronic form.

A 66 year old woman with end-stage renal disease and liver cirrhosis due to chronic hepatitis C virus infection was introduced to hemodialysis therapy in 2003. In 2007, hepatocellular carcinoma was identified and the patient underwent radio frequency ablation (RFA) and ethanol injection therapy (EIT) under laparotomy. A large vaginal tumor was incidentally found at gynecological examination. Histological diagnosis was diffuse large B-cell lymphoma (Stage IE). During the first course of chemotherapy, the vaginal tumor began to prolapse from the vaginal wall due to an excellent response to the chemotherapy and finally was resected. The patient received another course of chemotherapy followed by radiotherapy. The vaginal tumor was undetectable in the follow-up imaging studies. Although patients with end-stage renal disease are at increased risk for several cancers, the occurrence of malignant lymphoma following hepatocellular carcinoma is rare. Furthermore, lymphomas arising from the female genital tract are very uncommon.
