Pseudomonic acid, a new wide-spectrum antimicrobial agent, was evaluated as a 2% formulation in a cream. Animal studies showed that this formulation was just capable of penetrating the skin. When administered parenterally to animals, pseudomonic acid was converted to inactive metabolites that were quickly eliminated from the body. When pseudomonic acid was applied as a cream to human skin, no sensitization was observed. In an open clinical study, sixty-eight patients with skin infections (mostly superficial conditions such as impetigo, infected eczema, folliculitis, or balanitis) applied pseudomonic acid cream three times a day for 5 days. In fifty patients the infections completely cleared within 2 days of the end of therapy, and considerable clinical improvement was noted in sixteen more. One patient stopped the treatment prematurely due to local burning pain, and one patient could not be evaluated clinically.

Carbocalcitonin spray administered for 12 months at a daily dosage of 80 U MRC according to five schedules has been tested on 150 normal spontaneous postmenopausal women for its influence on bone mineral density (BMD), bone metabolism and osteoarticular pain. BMD was monitored before and at the end of treatment in comparison with BMD of untreated control women. Metabolic markers (serum alkaline phosphatase, serum osteocalcin and urinary hydroxyproline) were also evaluated before and during treatment (at the 9th or 10th month of treatment). Osteoarticular pain was assessed by an analogic visual scale. Intranasal carbocalcitonin, administered according to cyclic schedules at a high frequency dosage, was able to maintain bone mass only in the earlier postmenopausal women. BMD percent increase after 12 months of treatment was 1.10 and 1.31 in women with low (< 0.870 mg/cm2) and high baseline BMD (> or = 0.870 mg/cm2), respectively. In advanced menopause the maintaining effect of carbocalcitonin on BMD seemed evident only if the baseline bone mass was lower than the BMD of the age matched control group. At least six months of treatment/year is necessary for effective therapy. Both systemic and local tolerance were optimal. No significant side-effects were detected.

MVP chemotherapy (mitomycin C 8 mg m(-2), courses 1, 2, 4 and 6, vinblastine 6 mg m(-2), cisplatin 50 mg m(-2)) is an active low-toxicity regimen in non-small-cell lung cancer (NSCLC). Based on the single-agent activity of these agents in SCLC, we have conducted a phase II trial of MVP in SCLC. Fifty chemo-naive patients with SCLC were entered in this trial. There were 33 men and 17 women with median age 66 years (range 46-83 years); 18 patients had limited disease (LD) and 32 extensive disease (ED). WHO performance status (PS) was: three patients PS 0, 33 patients PS 1, ten patients PS 2, four patients PS 3. A maximum of six cycles was given in responding patients. On completion of chemotherapy, patients with LD obtaining complete response (CR)/good partial response (PR) received thoracic irradiation and those obtaining CR were offered entry into the ongoing MRC Prophylactic Cranial Irradiation Trial. The overall response was 79% with 17% CR and 62% PR. For LD patients, 38% obtained CR but for ED only one patient achieved CR. Median response duration for LD patients was 8 months and for ED patients 5 months. Median survival was 10 months for LD patients and 6 months for ED patients. There was complete resolution of symptoms in 24%, partial improvement in 68%, no change in 2% and progressive symptoms in 6%. As regards toxicity, 24% developed WHO grade 3/4 neutropenia, 16% grade 3/4 thrombocytopenia and 6% significant hair loss. Two patients died during the first week of treatment with neutropenic infection. Quality of life using the EORTC questionnaire (QLC-C30) with lung cancer module demonstrated significant improvements from baseline levels in emotional and cognitive functioning, global QOL, of pain, dyspnoea and cough. MVP, an effective palliative regimen for NSCLC, is also active against SCLC with low toxicity and merits comparison with more toxic conventional schedules.

Treatment of chronic myeloid leukaemia (CML) with IFN-alpha (IFN) is known to confer significant survival benefit, but the drug's impact on quality of life (QoL) in CML is unclear. We describe a cross-sectional comparison of QoL in patients randomised to long-term treatment with IFN versus no IFN within the UK MRC CML 3 trial, assessing the long-term consequences and psychosocial side effects of IFN therapy. Patients completed the EORTC QoL QLQ-C30, an in-house leukaemia/IFN questionnaire, a brief assessment of sexual functioning and demographic details. In total, 163 eligible patients completed questionnaires (85% response). Patients receiving IFN reported significantly worse QoL for emotional, cognitive and social functioning, pain and dyspnoea (P<0.01), and marginally worse fatigue, nausea and vomiting (P<0.05). As expected from other IFN use, those on IFN experienced more flu-like and febrile symptoms and skin problems than those not on IFN. In all, 35% of patients stopped IFN before questionnaire completion. This made no material difference to the results, except that those continuing on IFN had slightly better self-assessed Global health/QoL than those who had stopped (P<0.03). IFN treatment adversely affected sexual health after allowing for age and gender. In conclusion, IFN treatment has a significant adverse impact on QoL. Patient awareness of the survival benefits and these QoL effects should enable better-informed decision-making. The impact on QoL of IFN dose, and of imatinib therapy versus IFN in early CP CML, are being investigated. QoL will need evaluating in future studies of combination treatment (IFN+imatinib).

Current antispastic medications are unsatisfactory for spasticity treatment, but botulinum toxin type A (BTX-A) shows promise as a new therapeutic option. This open-label, prospective study aimed to assess the effectiveness of BTX-A in improving functional mobility in the early post-stroke population using an individualised, flexible range of doses and targeted muscle groups. Twenty-one stroke patients (13 male, 8 female) were enrolled and injected with BTX-A (Botox, Allergan, mean dose: 255 U; range: 185-300) according to individual spasticity patterns. Assessments were made at baseline and weeks 2, 4, 6, 10 and 16 post-treatment. Outcome measures comprised: Modified Ashworth Scale (MAS), finger flexion scale (Bhakta), MRC scale, Physician's Rating Scale (PRS), Nine Hole Peg Test (9HPT), Motor Assessment Scale, Clinical Global Impression (CGI), Global Assessment of Spasticity (GASS) and Visual Analogue Scale (VAS) for pain assessment. Statistically significant improvements in muscle tone as determined by the MAS were found in all areas (except arm) till week 16 (p<0.05). Finger positioning improved for the study duration, whilst muscle power increased only slightly in specific muscles. PRS revealed significant improvements to week 10 and slight improvement in 9HPT performance in selected patients was observed. Motor Assessment Scale results were statistically significant for arm, hand and advanced hand functions, although the overall functional benefit was mild. GASS and CGI results also showed improvement. Pain was present only in 11 patients and did not significantly improve following treatment. Individualised BTX-A injection regimens may be an effective, reversible and safe new treatment option for patients with spasticity. Nevertheless, functional improvement may be reached only in selected patients.

The active constituents of cannabis (predominantly cannabinoids and possibly flavonoids) are more effective than a single cannabinoid in reducing muscle spasticity in a multiple sclerosis animal model. Possible interactions include both pharmacokinetic and pharmacodynamic effects. Synthetic cannabinoids with agonist or antagonist/inverse agonist effects are available with high affinity for cannabinoids receptors. Pharmaceutical products that block their uptake and metabolism may enhance the endocannabinoid system. Government- and charity-funded clinical trials of cannabis are proceeding in pain, both acute (MRC multicenter trial) and chronic, and multiple sclerosis (MRC and Multiple Sclerosis Society multicenter trials). The design of these trials should enable evidence to be presented to regulatory bodies documenting the medicinal uses of standardized cannabis plant material.

Earlier reports on homozygous sickle cell (SS) disease have been biased by severely affected cases. The Jamaican clinic which seeks to avoid such bias has 102 patients surviving beyond 60 years. The objective of this study was to examine the features of elderly cases and assess factors determining survival and the behaviour of this disease with advancing age. A retrospective review of all cases and prospective assessment in survivors was conducted at The Sickle Cell Clinic at the University of the West Indies, Kingston, Jamaica previously operated by the MRC Laboratories. All patients with SS disease born prior to December 31, 1943 who would, by January 2004, have passed their 60th birthday were traced and their current status ascertained. The molecular and clinical features were assessed and observations on the clinical behaviour of the disease and of haematology and biochemistry are presented. Of the 102 patients, 58 had died, four had emigrated and 40 were alive, resident in Jamaica and aged 60-87 years. Survival was associated with female gender and higher foetal haemoglobin but not with alpha-thalassaemia or beta-globin haplotype. A tendency to familial clustering among elderly survivors did not reach statistical significance. Painful crises ameliorated with age and there was a benign course in pregnancy. Mean haemoglobin levels fell with age and were generally associated with rising creatinine levels indicating the importance of renal failure. Elderly survivors present some features of intrinsic mildness but also manifest age-related amelioration of painful crises and falling haemoglobin levels from progressive renal damage.

Acute apical abscesses and cellulitis are severe endodontic diseases caused by opportunistic bacteria with possible coinfection with latent herpesviruses. The objectives of this study are to identify herpesviruses, including human cytomegalovirus (HCMV), Epstein-Barr virus (EBV), herpes simplex virus-1 (HSV-1), and Varicella zoster virus (VZV) in patients (n = 31) presenting with acute apical abscesses and cellulitis of endodontic origin. Primary and nested polymerase chain reaction (PCR) was conducted using virus-specific primers and DNA isolated from cell-free abscess fluid. From patients exhibiting concurrent spontaneous pain (n = 28), nine abscesses contained HCMV, two abscesses contained EBV, one abscess contained HSV-1, and no abscesses contained VZV. Control PCR using genomic or recombinant templates showed detection limits to a single genomic copy of HCMV, 100 genomic copies for EBV, and 1 to 10 copies for HSV-1 with no cross-amplification between herpesviral DNA targets. Nested PCR was required for detection of herpesviral DNA in the abscess specimens, indicating that these viruses were present in low copy number. Filtration of abscess specimens and virus transfer experiments using human fibroblastic MRC-5 cells confirmed the presence of HCMV particles in several abscess specimens. We conclude that herpesviruses are present but not required for the development of acute apical abscesses and cellulitis of endodontic origin.

The aim was to assess factors that might influence health-related quality of life (HRQoL) in patients with two different neuromuscular disorders - myotonic dystrophy type 1 (DM1) and amyotrophic lateral sclerosis (ALS). A cross-sectional study was performed on 79 patients with DM1 and 74 with ALS. The HRQoL was evaluated by SF-36, Serbian version. Depressive and anxiety symptoms were assessed using the Hamilton rating scale for depression and the Hamilton rating scale for anxiety respectively. Severity of muscular involvement in DM1 was measured with MRC scale and severity of ALS with ALSFRSr score. The mean total score as well as all domain scores of SF-36 were similar in DM1 and ALS patients (p > 0.05), except that ALS patients experienced less bodily pain (p < 0.05). Depressiveness was found in 51% and marked anxiety in 38% of DM1 patients. Emotional status and severity of muscular involvement emerged as significant independent contributing factors to the total SF-36 in DMI patients (p < 0.05). Only 3% of ALS patients showed depressiveness and 4% anxiety symptoms. The factors found to contribute to HRQoL in ALS patients were severity of disease and educational level ofpatients (p < 0.05). We found significant percentage of potentially treatable emotional disturbances which together with severity of disease significantly contributed to HRQoL in DM1 patients. On the other hand, in ALS patients depressiveness and anxious symptoms were uncommon and the factors found to contribute to HRQoL were severity of disease and educational level.
