Some patients report superimposed paroxysms of stabbing ice pick-like pain in the periorbital region that lasts for a few seconds and occur once or several times in rapid succession proven 4 mg aristocort. Over 50 percent of sufferers report that alcohol is a potent precipitant of cluster headaches during a cluster bout; this sensitivity to alcohol ceases when the cluster ends discount aristocort 40mg with mastercard. The frequency of attacks depends upon the type of cluster: Episodic cluster headaches are most common purchase 40mg aristocort visa, occurring in about 80 to 90 percent of patients suffering from this disorder. They are characterized by one to three attacks of periorbital pain per day over a six to twelve week period, followed by an average pain free interval of six months to one year. Chronic cluster headaches are characterized by the absence of sustained periods of remission. Attacks of pain tend to recur at the same hour each day for the duration of a single cluster; attacks occur between 9 pm and 9 am in up to 80 percent. University of South Alabama, Department of Family Medicine June 30, 2008 152 Management: Abortive therapy — Abortive therapy of cluster headaches can be difficult because of the short duration of each episode. Nevertheless, a number of medications have proven effective Oxygen — Acute cluster headaches can be aborted by inhalation of 100 percent oxygen in the majority of patients. Octreotide —appears to be effective and well tolerated in the treatment of acute cluster headaches. Prophylaxis — Prophylactic therapy should be started as soon as possible at the onset of a cluster episode. Verapamil was found to be effective for prophylaxis but there is a four to six week delay before the headaches remit. Prednisone is highly effective for prophylaxis, but should not be used chronically due to side effects. Lithium appears to be particularly effective for the chronic form of cluster headaches. Ergotamine, Cyproheptadine, and Indomethacin have also been shown to be effective. Prophylactic medications can be tapered after the expected duration of the cluster has passed. Strength of Recommendations Key clinical recommendation Label The first-line treatments for acute cluster headache are oxygen or sumatriptan, or a A combination of the two. Less well-studied alternatives for acute treatment include intranasal dihydroergotamine, B intranasal lidocaine, and intranasal capsaicin. Verapamil, in a dosage of 360 to 480 mg daily, can effectively reduce the number of attacks A during a cluster headache period. Less well-studied alternatives for prophylaxis include prednisone and antiepileptic drugs; B they should only be considered if verapamil is not tolerated or not effective. A = consistent, good-quality patient-oriented evidence; B = inconsistent or limited quality patient-oriented evidence; C = consensus, disease-oriented evidence, usual practice, opinion, or case series. Surgical Therapy: Patients with chronic cluster headaches that do not respond to medications may be considered for surgical therapy aimed at the trigeminal nerve. A case series found that 15 of 17 patients who underwent complete or partial section of the trigeminal nerve had complete or near- complete relief of symptoms.

Arrange for definitive care of identified specific causes of throat pain at time of presentation or with appropriate follow-up 10. General approach to history: The history for pharyngitis is primarily to establish risk of the symptom being caused by a life threatening condition and to determine whether the patient has streptococcal pharyngitis. This is done initially by observing the patient for signs of toxicity, and listening to the quality of the patient’s voice. Following this, the time course of the illness and associated symptoms will give important clues as to whether this is infectious due to bacterial causes, infectious due to viral causes, inflammatory, or related to another disease process (such as Gastroesophageal Reflux Disease) Vocal Quality - Location – Where does your throat hurt? If a life threatening infection is suspected, further testing in a hospital setting might include direct visualization (epiglottis, peritonsilar abscess, palatal cellulitis, diptheria), diagnostic imaging (abscess). Patients over 15: A number of diseases and conditions can cause symptoms of pharyngitis. In patients with persistent symptoms, consider immunologic testing for connective tissue diseases. In patients with persistent symptoms and exposure to tobacco and/or alcohol referral for direct visualization might be warranted, particularly of the symptoms are associated with voice changes, weight loss, or other worrisome signs. If a life threatening infection is suspected, further testing in a hospital setting might include direct visualization (epiglottis, peritonsilar abscess, palatal cellulitis, diptheria), diagnostic imaging (abscess). Topical anesthetics such as Chlorasceptic spray help patient to tolerate symptoms until infection resolves and assist with maintaining hydration. Ingestion of fluid that is not at room temperature (either warmer or colder) is often easier for the patient. Cure rates with oral regimes dosed anywhere from every 12 to every 6 hours have been found to be equivalent.

Ono K, Hasegawa K, Naiki H, Yamada M (2004) J Neurosci Res 75:742 Chapter 3 Research into Isofavonoid Phyto-oestrogens in Plant Cell Cultures M. The physiological and pharmacological properties of isofavones are discussed in the Introduc- tion. The accumulation of phyto-oestrogens by plant cell and tissue cultures is reviewed. A special emphasis is put on the infuence of basic experimental me- dia and physiological factors on the production of isofavonoids in in vitro cul- tures. The potential role of the transformation process as well as the techniques (including infection with bacteria and particle bombardment) and the various technological procedures (elicitation, feeding experiments) in isofavone bio- synthesis is discussed. Moreover, this chapter deals with the in vitro cultures of legume plants oriented for selective accumulation of phyto-oestrogens. Strictly controlled conditions and constant access to stable biological material made it possible to conduct basic research into plant physiology on a much larger scale than before, leading to the expla- nation of numerous biochemical processes that constitute primary and second- ary tissue metabolism [3, 4]. It was also proved that plant biomasses cultivated in vitro are capable of biosynthesis of secondary metabolites typical for intact plants, or that they may serve as sources of entirely new substances not identi- fed in nature [3–10]. In effect, a path was opened for intensive biotechnological research into the potential use of in vitro cultures to produce highly valuable secondary metabolites, including compounds for which medical applications could be found [10–13]. Statistical research indicated that even in developed countries, where the broadly understood chemical synthesis is the basis for the pharmaceutical in- dustry as such, still as much as 25 % of all medicines are compounds of natural origin. Steady degradation of the environment, slow growth of plants, com- mon problems with low concentrations of active substances in the cultivated plants are only some of the factors that make it diffcult to obtain biologically active substances from natural sources. With the aforementioned obstacles and the need to cultivate tropical species in a temperate climate, in vitro cultures came to be seen as an alternative method for producing secondary metabolites with particularly valuable therapeutic properties [3, 14]. Among the numerous secondary metabolites, it is isofavonoids, together with alkaloids and terpenoids, that are natural compounds most commonly re- searched under in vitro conditions [9, 10, 15]. The reason for this may be seen in their multidirectional biological activity [16, 17]. Isofavones, being recognised phytoalexins and phytoanticipins, play a key role in the defence mechanisms in plants of Fabaceae family. That is why plant biomasses obtained from various species of legume plants became model systems for testing the defence response of plants to broadly defned environmental stresses [18, 19]. Isofavones are, in addition, secondary metabolites with broad health-promoting activity. In ad- dition to the anti-infammatory, antifungal and anti-free-radical activities that are typical for the whole group of biofavonoids, they also have features typical for compounds that inhibit oestrogen β receptors in mammals [16, 17, 20–22]. For this reason, among other applications, they are commonly recommended for the treatment of menopause symptoms [21, 23]. Moreover, some consider- ation is given to the possible using isofavones in the prevention and treatment of neoplasms related to the distortion of hormonal balance in the body [16, 17, 22, 24, 25]. Predominantly limited to soy-bean products, the natural sources of isofavones do not permit mass production of substantial amounts of these compounds, not only for the pharmaceutical industry, but also for the compre- hensive pharmacological and toxicological research of the isolated substances Chapter 3 Research into Isofavonoid Phyto-oestrogens in Plant Cell Cultures 57 [26]. Therefore, in recent years, only very few reports dealing with biotechno- logical research indicated the possibility of using in vitro cultures of certain species of the Fabaceae family for large-scale production of phyto-oestrogens [27, 28]. Irrespective of the main goal of a research project, the biosynthesis and metabolism of isofavonoids is stimulated in in vitro cultures by using both traditional as well as more advanced biotechnological strategies [15, 26]. Such procedures as the modifcation of the basic composition of the experimental medium, with a focus on growth regulators [29–33] and the regulation of the growth conditions by controlled lighting and temperature, should be mentioned [30, 34, 35]. The natural enzymatic potential of the investigated biomass is also used to induce broadly understood bioconversion with the use of direct and indirect precursors, in order to obtain the fnal product [36–38]. Based on the fact that isofavones belong to a class of substances that play an active role in defence processes [18, 19], the biosynthesis and metabolism of these compounds in plant cells is regulated using a wide range of biotic and abiotic elicitors [39–43]. Sample tests of isofavone accumulation in various types of in vitro cultures (callus, suspension, roots and shoots) provide prelimi- nary insight into the production potential of the particular types of cultures [27, 28, 31–33, 44]. The metabolism of isofavones was also investigated using transgenic biomasses (suspensions, hairy roots, regenerated organs) obtained through genetic transformation with wild or pre-designed strains of bacteria [31, 45–47], or particle bombardment [48, 49]. The following discussion, based on current literature reports, presents the impact of the particular growth strategies on the biosynthesis and metabolism of isofavones in in vitro plant cultures. These modifcations involve both qualitative and quantitative changes in the macro- and microelements, sources of carbon and growth regulators respon- sible for the particular hormonal balance in the growth system [2, 5, 8, 9, 51]. The composition of these media, especially in terms of growth regulators, was selected to support the micropropagation of the investigated species or to ensure maximum growth of the biomasses [44, 52–56]. For instance, in callus and suspension cultures of the most frequently inves- tigated species of the Fabaceae family, such as Glycine max, Cicer arietinum, Phaseolus vulgaris, Lupinus albus and Medicago sativa, the growth regulators 58 M. Luczkiewicz of choice were most often kinetin and 2,4-dichlorophenoxyacetic acid (2,4-D) [27, 28, 37–39, 41, 42]. It should be noted here that the effect of the particular growth regulators on shoot initiation and elongation was variable and each time was species specifc [44, 55–63]. Only few reported experiments involving in vitro cultures of Fabaceae plants were directly focussed on the infuence of the basic composition of the experi- mental media on the accumulation of isofavones in the plant material [30–34, 55, 64, 65]. The other experiments showed that a signifcant increase in the concentra- tion of the discussed compounds in the biomasses can be achieved by reduc- ing the level of mineral salts in the growth media [64–66]. A reduction of am- monia salts and nitrites in the growth media caused Phaseolus vulgaris shoot cultures to synthesise several times more phaseolin and kievetone than control biomasses [34]. The process was accompanied by a generally increased expres- sion of genes related to the phenylpropanoid pathway and inhibition of cul- ture growth. Similarly, increased nitrogen content in the medium resulted in the concentration of phytoalexins in bean shoots being reduced by even 9 % [34].
