Porphyria cutanea tarda precipitated by ovarian stimulation during oocyte retrieval in a genetically susceptible female.

We report a case of 33-year-old female with underlying genetic susceptibility for familial porphyria cutanea tarda due to novel UROD variant (c.636 + 2 dupT) unmasked by transient exposure to supraphysiological oestrogen concentrations following a single cycle of successful controlled ovarian stimulation for oocyte retrieval. Use of oral oestrogen in the form of oral contraceptive pills and hormone replacement therapy has been well known to trigger active porphyria cutanea tarda phenotype in susceptible women. However, to date, the emergence of clinically overt porphyria cutanea tarda has not been reported in association with fertility treatment in the literature before.

Web-based Therapy Plus Support by a Coach in Depressed Patients Referred to Secondary Mental Health Care: Randomized Controlled Trial.

BACKGROUND: The evidence for the effectiveness of Web-based therapies comes mainly from nonclinical populations, with a few studies in primary care. There is little evidence from patients referred to secondary mental health care with depression. Adherence to Web-based therapies is often poor. One way to increase this is to create a new health service role of a coach to guide people through the therapy. OBJECTIVE: This study aimed to test in people referred to secondary care with depression if a Web-based therapy (The Journal) supported by a coach plus usual care would be more effective in reducing depression compared with usual care plus an information leaflet about Web-based resources after 12 weeks. METHODS: We conducted a randomized controlled trial with two parallel arms and a process evaluation that included structured qualitative interviews analyzed using thematic analysis. The coach had a background in occupational therapy. Participants were recruited face-to-face at community mental health centers. RESULTS: We recruited 63 people into the trial (intervention 35, control 28). There were no statistically significant differences in the change from baseline in Patient Health Questionnaire-9 (PHQ-9) scores at 12 weeks comparing The Journal with usual care (mean change in PHQ-9 score 9.4 in the intervention group and 7.1 in the control group, t41=1.05, P=.30; mean difference=2.3, 95% CI -2.1 to 6.7). People who were offered The Journal attended on average about one less outpatient appointment compared with usual care, although this difference was not statistically significant (intervention mean number of visits 2.8 (SD 5.5) compared with 4.1 (SD 6.7) in the control group, t45=-0.80, P=.43; mean difference=1.3, 95% CI -4.5 to 2.0). The process evaluation found that the mean number of lessons completed in the intervention group was 2.5 (SD=1.9; range=0-6) and the number of contacts with the coach was a mean of 8.1 (SD=4.4; range=0-17). The qualitative interviews highlighted the problem of engaging clinicians in research and their resistance to recruitment: technical difficulties with The Journal, which prevented people logging in easily; difficulty accessing The Journal as it was not available on mobile devices; participants finding some lessons difficult; and participants saying they were too busy to complete the sessions. CONCLUSIONS: The study demonstrated that it is feasible to use a coach in this setting, that people found it helpful, and that it did not conflict with other care that participants were receiving. Future trials need to engage clinicians at an early stage to articulate where Web-based therapies fit into existing clinical pathways; Web-based therapies should be available on mobile devices, and logging in should be easy. The role of the coach should be explored in larger trials.

A case of paraneoplastic elastosis perforans serpiginosa associated with ovarian malignancy.

Elastosis perforans serpiginosa (EPS) is a rare skin disorder in which there is transepithelial elimination of elastin fibers. It belongs to a group of perforating disorders of which there are four classic types. The EPS type is extremely rare. There have been no previous reports of elastosis perforans serpiginosa occurring as a paraneoplastic phenomenon. We report a case of paraneoplastic elastosis perforans serpiginosa in the setting of stage 4 ovarian cancer.

A randomised half body prospective study of low and medium dose regimens using the 308 nm excimer laser in the treatment of localised psoriasis.

This study compared two dose-escalation regimens using the 308 nm excimer laser treating localised plaque psoriasis, to determine the optimal regimen. A randomised, left-right body trial was designed including patients aged >18 years with localised plaque psoriasis (<10% body surface area). The standard/low dose regimen started at 70% of the minimal erythema dose (MED), with 20% dose increments. The medium dose regimen commenced at 200% MED, with 25% increments. Patients were treated until disease clearance or a maximum of 36 treatments. Fifteen patients aged 28-55 years completed the study. Psoriasis severity index scores analysed at weeks 0, 6 and 12 showed a significant reduction with each regimen (p < 0.0001). Six patients cleared, seven had significant improvement with uneven clearance of plaques and two failed. Average remission was four months (range 1-12 months). There was a significant reduction in DLQI (p = 0.014). Excimer laser improved psoriasis and reduced DLQI scores, but clearance was incomplete for many patients and remission was short-lived. Adverse effects of pain and blistering were commoner with the medium dose regimen, without any benefit in psoriasis clearance.

What is the relevance of contact allergy to sodium metabisulfite and which concentration of the allergen should we use?

BACKGROUND: The prevalence of contact allergy to sodium metabisulfite (SMB) has increased from the range of 1.4% to 1.7% to the range of 3.4% to 6.8% in published series over the past 20 years. AIMS: The aims of this study were to review contact allergy to SMB in our cohort and to investigate different concentrations to define the most appropriate concentration for patch testing. METHODS: Patient records were reviewed between February 2009 and December 2011 to obtain information on patient demographics, clinical presentation, and prevalence of contact allergy to SMB. Patients attending for patch testing, between January 2012 and June 2013, were tested with 3 strengths of SMB as part of the British standard series (1%, 0.1%, and 0.01%). RESULTS: Nine hundred ninety-six patients were patch tested to the British standard series including SMB 1% in petrolatum between February 2009 and June 2013, and 70 (7%) were positive. In the prospective group, 380 were tested to 3 concentrations of SMB (1.0%, 0.1%, and 0.01%). Fourteen patients (3.68%) had a positive patch test with 1% SMB, 7 to 0.1% SMB, and 3 to 0.01% SMB. There was exposure to SMB in 10 patients who cleared with avoidance at review 3 months later. The most frequent location of rash included face, hands, vulval, and perianal region. CONCLUSIONS: Our study confirms reports of increasing prevalence of SMB allergy. A detailed review of exposure in the prospective study showed that SMB is relevant in most patients, and 1% in petrolatum is the best concentration for patch testing.

Intravenous human immunoglobulin for treatment of folliculitis decalvans.

We report a case of folliculitis decalvans (FD) successfully treated with intravenous human immunoglobulin (HIG). Many conventional treatments with topical agents and oral antibiotics had failed to achieve disease remission, treatment with HIG at a dose of 2 g/kg for the first month, reduced to 1 g/kg for second to fourth months was therefore started, which resulted in rapid improvement and ultimately complete resolution of FD. Clinical improvement was noted after the first infusion of HIG and remission of inflammation was achieved after the fourth infusion. Disease remission was sustained for six months following the last HIG infusion. The exact mechanism of action of HIG is poorly understood. However, it is thought to act as an immunomodulatory agent by altering different components of immune functions. To our knowledge, this is the first case reported in the literature of FD successfully treated with intravenous HIG.

Trends in tinea capitis in an Irish pediatric population and a comparison of scalp brushings versus scalp scrapings as methods of investigation.

A retrospective study of 391 children with suspected tinea capitis was analyzed to examine the prevalence of dermatophyte species and to compare the efficacy of the scalp scraping method with that of the hairbrush method for diagnoses over a 6-year period. Trichophyton tonsurans tinea capitis is the most common pathogen. The hairbrush method of obtaining specimens for fungal culture was superior to scalp scrapings (p = 0.03) in making the diagnosis, and using two methods (p < 0.001) increased the yield of identifying a dermatophyte infection.
