Ketorolac IM was compared to DHE and metoclopramide IV in migraine patients whose regular abortive medication had failed and who presented to a headache clinic for acute treatment. Pain scale ratings and ratings of ability to function were recorded before and after injection. Ketorolac provided moderate relief in headache in six of nine patients compared to eight of nine given DHE and metoclopramide. The average improvement in patients receiving DHE and metoclopramide was greater in pain (p = .031) and disability scores (p = .057), than in those patients given ketorolac.

The antithromboembolic efficacy of once a day low molecular weight heparin in fixed combination with dihydroergotamine (LMWH-DHE) was compared with conventional heparin-DHE in combination with Acenocoumarol (heparin-DHE/A) in 191 patients undergoing gynaecological surgery. LMWH-DHE proved equally effective in preventing thromboembolic complications, with a similar incidence of postoperative bleeding and side effects. Deep vein thrombosis occurred once in each group and one non-fatal pulmonary embolism occurred in the LMWH-DHE group. The main advantage of LMWH-DHE was significantly better patient acceptance of the single daily subcutaneous injection as compared with the two injections of conventional heparin-DHE (P = 0.02). On the other hand, LMWH-DHE was associated with significantly increased incidence of intraoperative bleeding (P less than 0.02). The bleeding did not, however, cause any clinical problems. Discontinuation of therapy due to bleeding or pain at the site of injection occurred three times in each group. We consider the use of LMWH-DHE to be an attractive, economic and safe method of thromboembolic prophylaxis.

In a prospective study the complications of Heparin-Dihydroergotamine (HDHE) [2,500 units Heparin + 0.5 mg DHE] s c. twice daily as thromboembolic prophylaxis have been studied in patients undergoing a lumbar disc operation. During a two year period 616 patients were operated, 47 patients had to be excluded, 107 patients did not receive HDHE desired by the surgeon; 462 patients received HDHE as described in the protocol. Because the distribution of age, sex, duration of hospitalisation of the 107 patients without HDHE is the same as in the HDHE group, this group can be used as control group. Increased intraoperative bleeding--written down in the operation report--66 patients (14.3%) in HDHE group and 6 patients (5.6%) in the control group. There is no statistic significance between the both groups in superficial and deep wound hematomas, deep vein thromboses or pulmonary embolism. In the HDHE group two death appears. Both patients [a 37 year old, asymptomatic woman and a 65 year old man with mild ischemic symptoms 11 months prior to operation] died because of an acute myocardial infarction. The clinical course and the missing of stenosis or occlusion at autopsy let us think at the possibility of coronary arterial spasm, presumably caused by DHE, as the cause of myocardial infarction. We suggest not to apply HDHE to patients with coronary artery heart disease or with atypical thoracic pain.

For evaluating the role of photodynamic therapy (PDT) in the local treatment of acquired immune deficiency syndrome (AIDS)-related cutaneous Kaposi's sarcoma (KS), nine treatments were performed in eight human immunodeficiency virus-positive homosexual men. The patients received 2 mg Photofrin/kg and either 120 J/cm2 (n = 5) or 70 J/cm2 (n = 4) laser light (630 nm). A total of 83 lesions were evaluable for response with a follow-up of 3-8 months. The overall response rates by patient for all treated lesions were 50-100% (120 J/cm2) and 83.3-90.3% (70 J/cm2), with a median duration of 3 months (range, 2-6 months). Tumors located at the head had higher response rates than those at the trunk or extremities (p = 0.005 and p - 0.015 respectively). The size of the KS showed a negative relationship with the probability of complete response (p = 0.047). Local and general side effects occurred, including pain, blisters, temperature increase, muscle stiffness, and severe edema. The cosmetic result was unsatisfactory because of a high prevalence of scars and long-lasting hyperpigmentation. Although the response rates of PDT are high, light dose of 70-120 J/cm2 cannot be recommended in the treatment of cutaneous KS in combination with 2 mg/kg Photofrin because of severe side effects and unsatisfactory cosmetic result.

Esophageal carcinoma usually is diagnosed at an advanced, incurable stage. In patients with good operative risk, surgery is still considered the ideal treatment. Patients with coexisting major medical conditions in whom resective surgery is precluded may benefit from several therapeutic options, including photodynamic therapy (PDT) with porfimer sodium (Photofrin; manufactured by Lederle Parenterals, Carolina, Puerto Rico, under license from Quadra Logic Technologies, Inc, Vancouver, British Columbia, Canada), dilation, thermal destruction, Nd:YAG laser ablation, injection therapy, and placement of prosthetic tubes. Photodynamic therapy with porfimer sodium is thought to have a direct toxic effect on malignant cells via the production of singlet oxygen, which damages the microvasculature of the tumor and renders it ischemic. The 630 nm wavelength used for clinical PDT exhibits the greatest relative degree of light penetration into tissue, with corresponding activation of retained photosensitizer. The efficacy of PDT with porfimer sodium is closely related to stage of disease. It should be emphasized that PDT has been shown to be potentially curative in patients with early, noninvasive tumors of both squamous and glandular (adenocarcinoma) histologies. Eighty-three patients with esophageal carcinoma were treated using PDT. At presentation, 60% of patients had recurrence following previous radiotherapy or chemotherapy. Patients with less advanced disease had a better response to PDT with regard to relief of dysphagia and prolongation of survival. Photodynamic therapy was found to be more useful than Nd:YAG laser therapy for high, upper third lesions, especially circumferential ones. For tumors larger than 8 cm, PDT was twice as effective as Nd:YAG laser therapy in establishing prolonged lumen patency, especially for adenocarcinomas. Photodynamic therapy appears to have the added advantages of fewer treatments and less pain. The role of PDT in gastrointestinal malignancies continues to evolve.

Migraine headaches are common in children and adolescents, and stricter diagnostic criteria have been developed. Children have a variety of migraine syndromes, ranging from frequent, mild, bifrontal headaches to severe debilitating, unilateral pain associated with persistent motor or visual deficits. Neurodiagnostic studies are indicated in those individuals who have accompanying signs or symptoms that raise concern. The treatment of migraine must be individualized and requires more than just the use of pharmacotherapy. Reassurance and the elimination of potential triggering factors are essential components of care. Symptomatic therapy with analgesics and rest often is sufficient. Behavioral therapy, consisting of psychological support, relaxation exercises, and biofeedback training, is effective in reducing the frequency and severity of migraine. Ergotamines are valuable agents for abortive treatment, but should be reserved for use in the older child. Parenteral use of DHE is an effective treatment for the rare child who has an acute severe migraine unresponsive to other therapies. A variety of agents are available for the long-term stabilization of childhood migraine.

The incidence of carcinoma in situ (CIS) and dysplasia of the uterine cervix has been increasing among young women in recent years. Most of these patients want to preserve their fertility. Also, to accommodate high-risk patients with complications, elderly patients, and those who refuse surgery, we perform PDT as a method to preserve fertility. The technique required for PDT is relatively simple, and can be performed without anesthesia, since it causes no pain or bleeding. PDT, with the use of Excimer Dye Laser (EDL), a type of low pulse laser, has a considerably higher degree of tissue penetration, even compared to PDT using Argon Dye Laser (ADL). Also, PDT using EDL can manage glandular involvement of CIN, and its special feature of selective destruction of malignant cells with almost no effect on normal tissues is noteworthy. Beginning in 1995, PDT using YAG-OPO Laser with a variable laser wavelength has been performed. PDT is performed 48 hours after intravenous injection of 1.5 mg/kg to 2 mg/kg photosensitizer Porfimer sodium (PHE) when the difference in density of PHE becomes greatest between malignant cells and normal tissue. The most advanced features of our method compared to conventional radiation which uses cut fiber are: First, by using colposcope with an optical path for the laser, it is possible to show a 10 mm circular spot at the focus of observation. With this method, cervical lesions can be observed and checked while receiving stable and precise photoradiation by using colposcope through direct observation. Second, for cervical canal treatment, by using a cervical probe to administer photoradiation in the forward direction in the cervical canal and to the side walls, 70% of the laser light is scattered to the side walls, so that all of the cervical canal can be radiated. Also, the cervical canal probe used to administer photoradiation, by inserting 2 cm to 3 cm depending on the conditions of the cervical canal and withdrawing the probe 1 mm, can be performed precisely and promptly by using the cervical probe manipulator feature of the colposcope. At the present time, studies using the PDT method have been conducted on 56 patients (39 CIS and 17 dysplasia patients). Out of these 56 patients, there were 54 CR (96.4%), only one NC, and one PR with very limited remnants but most of the lesions had disappeared. The NC was highly suspected to be invasive carcinoma and the PR was CIS. In the CIS case, some remnant was evident at the end of the cervical canal, and PDT was administered again. After this treatment, it became CR. This was 10 months ago, and no abnormal condition has been reported since. The first CR case was reported 6 years ago among the 56 cases studied, and no recurrence has been observed to date. Five patients became pregnant after the treatment. Four had normal deliveries and one had a cesarean section. PDT's side effect is similar to symptoms of sunburn such as minor skin irritation due to sensitive reaction to sunlight. Normally, it can be relieved by applying carmine lotion, and even cases that required treatment were cured completely within a few days after applying steroid ointment. Before hospitalization, if the patient gets a sunburn from being outside, the sensitive reaction to laser light is almost nonexistent. Thus, we advise patients to get some exposure to the sun before being hospitalized. Also, in cases where strict shading time is observed, side effects are not apparent at all, and no abnormal findings are recognized in the blood and urine due to using PHE. With almost no side effects, bleeding or pain, and with certain improvements in administration methods, a better choice of photosensitizer which would shorten the shading time, PDT is considered to be the best therapy for treating CIS and dysplasia while preserving fertility.

Migraine is a common, complex neurophysiologic headache disorder. Most migraineurs have neither been diagnosed by physicians nor effectively treated. The clinical diagnosis of migraine is based on headache characteristics and associated symptoms, particularly nausea and vomiting. Pharmacologic symptomatic treatment is aimed at reversing, aborting, or reducing pain and the accompanying symptoms of an attack. Individualization of therapy is essential in determining whether symptomatic and/or preventive treatment for migraine attacks are needed. The presence of nausea and vomiting must be considered in developing a treatment plan. The patient's priorities and preferences regarding therapy must be taken into account. The goals of symptomatic treatment are to relieve pain and the associated symptoms and to optimize the patient's ability to function normally. Multiple treatment strategies utilizing combinations of 5-hydroxytryptamine1 (5-HT1) agonists (ergotamine tartrate [ET], sumatriptan, and dihydroergotamine [DHE]) with simple analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and opiates provide effective treatment for most attacks of moderate to severe migraine. Treatment strategies are based on the frequency, nature, and severity of attacks. Patients with intractable, acute migraine may require hospitalization and aggressive parenteral treatment. Wider use of currently available diagnostic criteria and symptomatic medications should improve the diagnosis and treatment of migraine.

The anti-migraine compound, sumatriptan, has been shown to have substantial affinity for the cloned human 5-HT1F receptor suggesting that, in addition to 5-HT1B/5-HT1D receptor subtypes, the 5-HT1F receptor may be a therapeutic target for the treatment of migraine. Several investigators have used the guinea pig plasma extravasation model to evaluate potential anti-migraine drugs. Since species differences in the pharmacology of serotonin receptors are well known, we compared the pharmacological profiles of the cloned human and guinea pig 5-HT1F receptors in order to validate the usefulness of the in vivo model in predicting anti-migraine activity of compounds targeted for humans. We have cloned the guinea pig 5-HT1F by homology to the human 5-HT1F receptor and evaluated its pharmacological profile using radioligand binding assays. The cloned guinea pig 5-HT1F gene exhibited 94% amino acid identity to the corresponding human homolog. High affinity (Kd approximately 10 nM) [3H]5-HT binding was detected to membranes obtained from Cos-7 cells transiently expressing the guinea pig 5-HT1F receptor. The cloned guinea pig receptor displayed typical 5-HT1F receptor pharmacology with the following rank order of binding affinities: 5-HT > sumatriptan > 1-NP = DHE > alpha-methyl 5-HT > metergoline > methiothepin > 5-CT. The pharmacological profiles of the cloned guinea pig and human 5-HT1F receptors were very similar as reflected by the high correlation (r2 = 0.72, slope = 0.76) observed between the binding affinities of compounds for these two species homologs. In situ hybridization studies in guinea pig tissue revealed 5-HT1F receptor mRNA expression in the neurons of the trigeminal ganglion, suggesting that the 5-HT1F receptor may play a role in the presynaptic inhibition of neuropeptide release at the level of the intracranial vasculature, thereby blocking the development of neurogenic inflammation. Dorsal root ganglion cells also moderately expressed the 5-HT1F transcripts. The localization of the 5-HT1F receptor to areas involved in the mediation and transfer of nociceptive information implies a role for this receptor in pain processing. These findings indicate that a selective 5-HT1F agonist may be a novel approach to treat migraine.

We have been performing PDT using Excimer Dye Laser (EDL) or YAG-OPO laser, a type of low power laser, both of which have a considerably higher degree of tissue penetration even when compared to PDT using Argon Dye Laser (ADL).PDT is a relatively simple procedure without any bleeding and does not require anesthesia since it causes no pain. PDT is performed 48 h after intravenous injection of 1.5-2.0 mg/kg of PHE (Photofrin((R))). Precise spot irradiation is possible using a colposcope with an optical laser path. We also use a cervical probe which enables photoirradiation of the entire cervical canal.We have performed PDT on 131 cases (95 CIS, 31 dysplasia, 1 vulval dysplasia (VIN), 3 squamous cell carcinoma, microinvasion, and 1 CIS + endocervical adenocarcinoma, microinvasion). Of these cases, 127 became CR (96.9%). The first CR case was 10 years ago and no recurrence has been observed yet.PDT is extremely effective to preserve fertility. Except for sensitive reactions to sunlight, there are no noticeable side effects or difficulties related to pregnancy or delivery. We expect that in the near future PDT will be performed using diode lasers and without hospitalization due to new photosensitizers which have shorter retention times.
