Psychological health in patients with genital and oral erosive lichen planus

BACKGROUND: Erosive lichen planus is a severe, recurrent and recalcitrant disease that affects several mucosal areas, mostly the genital area and the mouth, but also, for example, the oesophagus and perianal area. The disease causes serious symptoms, because of the raw, de-epithelialized mucosa and healing with scars/adhesions, which affect the patient's life in many ways. It causes, for example, difficulties in eating, drinking and going to the bathroom. Treatment is complicated and, so far, few therapeutic drugs other than steroids have been reported. OBJECTIVES: As the disease has severe implications on the patient's life it is important to investigate the psychological health of the patients, as well as the influence of stress on their health and wellbeing, in order to improve treatment. STUDY DESIGN, SUBJECTS AND METHODS: Forty-nine consecutive patients with erosive lichen planus were included during a 1-year period. The study was carried out as 'state-of-the-last-month', and stress, state anxiety, depression and 'erosive lichen planus factors', i.e. symptoms affecting daily life, were assessed. RESULTS: Eighty-seven per cent of the patients had symptoms, severely affecting daily life. Unexpectedly, oral symptoms seemed to be the most prominent. Our results showed that depression, anxiety and stress were more common in patients with erosive lichen planus than in a control group. DISCUSSION AND CONCLUSIONS: Erosive lichen planus is a severe disease with symptoms and complications affecting the patient's life. Our results indicate that their psychological health is also affected and emphasize the need for close collaboration between physicians, dentists with special knowledge in oral medicine and counsellors/psychologists to optimize handling of these patients.     

Profound decrease of in vivo formation of thromboxane during oestrogen therapy

Oestrogen has been proposed to influence platelet activity and formation of the vasoactive eicosanoids thromboxane and prostacyclin. Previous studies have been based on ex vivo techniques with well-known artifacts during blood sampling and ex vivo conditions. The present study is the first to assess in vivo formation through gas chromatographic/mass spectrometric analysis of the major urinary metabolites 2,3-dinor-thromboxane B₂ and 2,3-dinor-6-keto-PGF_1α. Ten consecutive male patients with prostatic carcinoma participating in a randomized study comparing the effects of parenteral oestrogen therapy ( n =5) with orchidectomy ( n =5) were included. Oestrogen was given as polyestradiol phosphate 240 mg i.m. every month. 2,3-dinor thromboxane B₂ and 2,3-dinor-6-keto-PGF_1α were analysed with the help of tetradeuterated internal carriers/standards. We found a consistent decrease of in vivo formation of thromboxane by ≈40% during parenteral oestrogen therapy ( P =0.008) and a doubling after surgical castration. The ratio of prostacyclin to thromboxane increased by ≈50% ( P =0.023) during oestrogen therapy. In conclusion, oestrogen induced a marked decrease of in vivo formation of thromboxane and a marked increase in the ratio of prostacyclin to thromboxane formation in all patients. According to current knowledge this should be beneficial for the cardiovascular system. Furthermore, thromboxane formation increased after surgical castration. The latter fact should direct attention to the influence of androgens on thromboxane synthesis. Our findings discloses a marked sex-hormone sensitivity of the thromboxane-forming system.     

The value of local registry data for describing cervical cancer management and outcomes over three decades in Australia

Registry data on invasive cervical cancers (n = 1,274) from four major hospitals (1984‐2012) were analysed to determine their value for informing local service delivery in Australia. The methodology comprised disease‐specific survival analyses using Kaplan‐Meier product‐limit estimates and Cox proportional hazards models and treatment analyses using logistic regression. Five‐ and 10‐year survivals were 72% and 68%, respectively, equating with relative survival estimates for Australia and the USA. Most common treatments were surgery and radiotherapy. Systemic therapies increased in recent years, generally with radiotherapy, but were less common for residents from less accessible areas. Surgery was more common for younger women and early‐stage disease, and radiotherapy for older women and regional and more advanced disease. The proportion of glandular cancers increased in‐step with national trends. Little evidence of variation in risk‐adjusted survival presented over time or by Local Health District. The study illustrates the value of local registry data for describing local treatment and outcomes. They show the lower use of systemic therapies among residents of less accessible areas which warrants further investigation. Risk‐adjusted treatment and outcomes did not vary by socio‐economic status, suggesting equity in service delivery. These data are important for local evaluation and were not available from other sources.     

Congenital chylothorax in siblings

We describe two cases of congenital chylothorax in siblings with important differences from previously described familial cases. Our findings support the likelihood of an autosomal recessive inheritance in some cases of this condition, rather than X-linked recessive inheritance, which has also been suggested. Autopsy findings from one of these cases and others previously described suggest that the pathophysiological mechanisms involved may be variable.

Effect of phagocytosis on the reduced soluble sulfhydryl content of human granulocytes

The role of reduced glutathione in relation to hexose monophosphate shunt activity and peroxide detoxification has been well established in human erythrocytes. Less is known about the content of reduced glutathione in phagocytic leukocytes and the changes that occur during functional activity. We have measured the reduced sulfhydryl content of normal resting human granulocytes and of cells isolated from a patient with chronic granulomatous disease. Normal cells and those from the patient with chronic granulomatous disease contained similar concentrations of reduced sulfhydryls. Stimulation of a phagocytic response by incubation with opsonized zymosan particles resulted in prompt and nearly complete depletion of intracellular glutathione from normal granulocytes. This fall in reduced glutathione concentration was dependent on the phagocytic load. Exposure of chronic granulomatous disease granulocytes to a similar phagocytic load resulted in a slower and less complete fall in reduced glutathione. In normal cells, those from the chronic granulomatous disease patient, and those from an obligate carrier of the disease, the decrement in reduced glutathione during phagocytosis was correlated with oxidation of 14C-1-glucose and 14C-formate, nitroblue tetrazolium reduction, and the chemiluminescence phenomenon.

Salbutamol for hyperkalaemia in children

Hyperkalaemia is a potentially fatal disorder that demands direct treatment. The efficacy of traditional medical treatment is unpredictable, limited, of short duration or carries the risk of serious adverse events. The administration of salbutamol for hyperkalaemia in children is described in several clinical trials and case reports.

Conclusion: Salbutamol, inhaled or infused, is safe and efficacious and results in a predictable and long-lasting reduction in serum potassium. Salbutamol merits a place as the preferred medication for hyperkalaemia in children without arrhythmias. If follow-up with haemodialysis is required, the administration of salbutamol gives time to make the necessary preparations.     

Anti‐infliximab antibody status and its relation to clinical response in psoriatic patients: A pilot study

Although the mechanisms underlying the loss of response to infliximab are not completely understood, the formation of antibodies to infliximab (ATI) are thought to play a role. The aim of this study was to investigate the presence of ATI in psoriatic patients and to evaluate its relationship to the clinical response. Fifteen patients with psoriasis were treated with infliximab (5 mg/kg) every 8 weeks after an initial three‐dose induction treatment. An enzyme linked immunosorbent assay kit was used for analyzing the presence of ATI in sera. Effectiveness assessments included the change in Psoriasis Area and Severity Index (PASI) compared with study entry. Five (33.3%) patients developed ATI. While 5.9 ± 3.2 infliximab infusions achieved a fall in the PASI score from a mean of 20.4 ± 8.3 to 5.3 ± 2.4 in ATI‐negative patients, these values changed from 23.3 ± 11 to 10 ± 4.9 after 9 ± 5.2 infusions in ATI‐positive patients. Our results suggested that ATI measured in psoriatic patients are of clinical importance. Therefore, monitoring for the induction of ATI and rescue strategies should be developed to avoid or to maintain a delay in ATI development.
