Noncicatrizing alopecias; with special reference to alopecia areata

Since the epochal work of Hamilton there has been general acceptance of the causal relationship of the male sex hormone, age and familial inheritance in development of male pattern baldness. Some of the medicaments used in recent years may cause a diffuse loss of scalp hair. Alopecia that accompanies disease states is probably due to generalized toxemia and disturbances in metabolism. Sometimes male pattern baldness occurs in physiologic states, as exemplified by diffuse hair loss occasionally in the postpartum period. Alopecia areata deserves a critical appraisal, since it may be evidence of underlying neuropsychotic states that need psychiatric diagnosis and treatment. The development of alopecia totalis or universalis in 50 per cent of the prepuberal cases of alopecia areata is of real significance, especially since so very few patients recover their normal scalp hair. The conclusions reached by the authors of two articles reporting on 368 cases of alopecia areata, alopecia totalis and alopecia universalis that the evidence is overwhelming against the malfunction of the endocrine glands as the cause of alopecia areata must be considered real contributions to our understanding of this condition.A few conditions simulate alopecia areata. Probably the ones which are seen most often are trichotillomania and patchy baldness caused by agents used in hair waving and straightening. Our findings in 22 cases of alopecia areata of a persistent inflammatory perivascular and perifollicular infiltrate, massive plugging of the ostia, disappearance of robust hair follicles and diminution in total number of hair follicles and sometimes fibrosis are not necessarily diagnostic of alopecia areata but seem to be very definitely characteristic. Treatment for alopecia areata is of little avail. At this time we do not recommend the general use of the corticosteroids despite the improvement of scalp appearance in the majority of instances in which the systemic administration of these hormones have been employed.

Topical minoxidil in the treatment of alopecia areata.

A modified double blind crossover study was performed to assess the effect of 1% topical minoxidil as compared with placebo in 30 patients with alopecia areata and alopecia totalis. The active preparation produced a highly significant incidence of hair regrowth. A cosmetically acceptable response was noted in 16 patients. No side effects were seen. The study confirmed that topical minoxidil will induce new hair growth in alopecia areata but that it is less likely to do so in more severe and extensive disease. Furthermore, patients with alopecia universalis and totalis may not respond at all. Nevertheless, as compared with other drugs minoxidil applied topically is relatively non-toxic, is easy to use, and has no systemic or local side effects.     

Alopecia Totalis in a Chimpanzee

A case of alopecia totalis in a chimpanzee is reported. The disease was probably due to an autoimmune phenomenon and was successfully treated with immunosuppressive therapy. However, possible side-effects outweighed benefits.     

Beclomethasone dipropionate in asthma.

Beclomethasone dipropionate aerosol therapy can replace or diminish systemic corticosteroid therapy in the majority of asthmatics. In a clinical trial of 41 patients with perennial asthma, the 10 who had not required long-term corticosteroid therapy improved symptomatically and in pulmonary function. Of the 31 who had required prolonged systemic corticosteroid therapy 12 were able to discontinue oral prednisone therapy, 15 were able to decrease the maintenance dose of prednisone and only 4 were unable to decrease the dose; all maintained satisfactory lung function and some showed improvement. Discontinuation of systemic corticosteroid therapy was accomplished more readily in patients whose daily maintenance dose was less than 15 mg and who had been taking the drug for less than 3 years. Side effects consisted of a "dry throat" in seven patients, two of whom had throat infections with Candida albicans. Recurrence of rhinitis after discontinuation or reduction of systemic corticosteroid therapy was noted in 11 patients.     

Methods of hair loss evaluation in patients with endocrine disorders

Hair loss may accompany several endocrine disorders, including hypopituitarism, hypothyreosis, hyperthyreosis, hypoparathyroidism, diabetes mellitus, growth hormone deficiency, hyperprolactinaemia, polycystic ovary syndrome, SAHA syndrome, congenital adrenal hyperplasia, Cushing syndrome, or virilising tumours. Most patients with endocrine disorders present with diffuse non-scarring alopecia, such as anagen effluvium, telogen effluvium or androgenetic alopecia. Focal non-scarring alopecia, such as alopecia areata coexisting with autoimmune thyroiditis, is less frequent and scarring alopecia is a rare finding in patients with endocrine abnormalities. In some cases an endocrine disorder may be suspected based on dermatological findings during hair loss evaluation. Classic methods of hair evaluation include hair weighing, pull test, wash test, the trichogram, and histopathological examination. Newly developed non-invasive diagnostic techniques include the phototrichogram, trichoscan, trichoscopy, and reflectance confocal microscopy.

Bone grafts as vancomycin carriers in local therapy of resistant infections

The level of an antibiotic capable of inhibiting the etiological agent at the site of infection is an essential prerequisite for successful antibiotic therapy. In some cases, locally applied antibiotics may compensate for limitations of systemic administration and shorten systemic therapy. We aimed at verifying to what extent vancomycin (Van) bound to ground bone grafts is usable in the treatment of serious infections. The levels of released Van significantly exceeded the Van minimum inhibitory concentration, which can suppress Van-sensitive staphylococci and Van intermediate Staphylococcus aureus, for the whole period of a 16-day measurement. Our results indicate that bone grafts can be used as Van carriers in therapy of osteomyelitis caused by Van-sensitive Staphylococcus strains.     

PSYCHOSIS AND SYSTEMIC LUPUS ERYTHEMATOSUS—A Review of the Literature and Case Reports

In a review of the literature of the last 60 years concerning the association between psychosis and systemic lupus erythematosus, reports of 227 cases of this association were found. The average incidence of psychosis in the various series of systemic lupus erythematosus that were reviewed was 22 per cent. In only 25 per cent of the cases in which the information was given was the psychosis associated with steroid therapy.The psychiatric manifestations are variable and may be associated with a neurological disorder. Psychosis may antedate by many years other features of lupus. The psychosis due to lupus may respond to steroid therapy. Since systemic lupus erythematosus sometimes may be an important differential diagnosis of functional psychosis, appropriate diagnostic studies should be carried out in psychotic patients who have an accelerated sedimentation rate or positive serological test for syphilis without apparent reason.     

Fatty acid supplements improve hair coat condition in rhesus macaques

As captive rhesus macaques often exhibit hair loss, alopecia was quantified and behavior was recorded before, during, and after fatty acid supplementation in six macaques. Fatty acid treatment was associated with a decrease in alopecia and in self‐grooming behavior. Therefore, fatty acids may be a viable treatment for alopecia in some captive primates.     

Possibility of using TFX (thymus factor X) in the treatment of systemic lupus erythematosus

A case of a 32-year female patient with the systemic lupus erythematosus is presented. The patient was treated with prednisone in a daily dose of 40-60 mg. Due to the exacerbations of the symptoms and advanced renal disorders, the patient was given TFX together with corticotherapy. Thymus factor X is an extract of real thymus of immunorecorrective properties. It specifically acts on the lymphatic system, especially disordered mechanisms of both cellular and humoral immunity. Thymus factor X was given in the dose of 10 mg (one ampoule) i.m. for the three first months followed by one ampoule every three days for the next three months. The patient is given one ampoule of TFX once a week since the 6th months of therapy. Diminishment of the symptoms was observed. The patient is in remission since a one-year follow-up period. It was also possible to reduce the dose of prednisone to 15 mg a day. The patient is controlled every 3 months. Partial normalization of renal functioning and immunological mechanisms are seen. A decrease in antinuclear antibodies and immunoglobulins, normalization in complement components, an increase in T-cells percentage and conversion of the delayed skin reaction are noted. The authors conclude that TFX may be helpful in the treatment of the autoimmunological diseases, including the systemic lupus erythematosus.     

Tumor necrosis factor alpha (TNF-α) gene polymorphism in alopecia areata

Tumor necrosis factor alpha (TNF-) phenotypes of two polymorphic systems were determined in 50 patients with alopecia areata, a common inflammatory disease of the skin. The distribution of TNF- T1, T2 phenotypes differed between patients with the patchy form of disease and patients with totalis/universalis disease. There was no significant difference in the distribution of TNF- G,A phenotypes between patient groups. The results of this study provide evidence of genetic heterogeneity between the two forms of alopecia areata, and suggest that the TNF- gene or a closely linked locus within the major histocompatibility complex may play a role in the pathogenesis of the patchy form of disease.     

Chronic hepatitis B exacerbation following a short prednisone therapy resulting in death]

A case of a 36-year male patient with chronic active hepatitis B is described. A short-term prednisone therapy resulted in the exacerbation of the disease leading to hepatic failure and patient's death. A short-term corticotherapy in some patients with chronic active hepatitis B may prove fatal.     

A single-tube allele specific-polymerase chain reaction to detect T315I resistant mutation in chronic myeloid leukemia patients

Despite the proven success of hormonal therapy for prostate cancer using chemical or surgical castration, most patients eventually will progress to a phase of the disease that is metastatic and shows resistance to further hormonal manipulation. This has been termed metastatic castrate-resistant prostate cancer (mCRPC). Despite this designation, however, there is evidence that androgen receptor (AR)-mediated signaling and gene expression can persist in mCRPC, even in the face of castrate levels of androgen. This may be due in part to the upregulation of enzymes involved in androgen synthesis, the overexpression of AR, or the emergence of mutant ARs with promiscuous recognition of various steroidal ligands. The therapeutic options were limited and palliative in nature until trials in 2004 demonstrated that docetaxel chemotherapy could significantly improve survival. These results established first-line docetaxel as the standard of care for mCRPC. After resistance to further docetaxel therapy develops, treatment options were once again limited. Recently reported results from phase 3 trials have shown that additional therapy with the novel taxane cabazitaxel (with prednisone), or treatment with the antiandrogen abiraterone (with prednisone) could improve survival for patients with mCRPC following docetaxel therapy. Compared with mitoxantrone/prednisone, cabazitaxel/prednisone significantly improved overall survival, with a 30% reduction in rate of death, in patients with progression of mCRPC after docetaxel therapy in the TROPIC trial. Similarly, abiraterone acetate (an inhibitor of androgen biosynthesis) plus prednisone significantly decreased the rate of death by 35% compared with placebo plus prednisone in mCRPC patients progressing after prior docetaxel therapy in the COU-AA-301 trial. Results of these trials have thus established two additional treatment options for mCRPC patients in the "post-docetaxel space." In view of the continued AR-mediated signaling on mCRPC, results from additional phase 3 studies with novel antiandrogens which are directed at inhibition of the AR (e.g., MDV3100), as well as other agents, are awaited with interest and may further expand the treatment choices for this difficult-to-manage population of patients.     

Serum Th1 and Th2 profile cytokine level changes in patients with Graves' ophthalmopathy treated with corticosteroids.

The aim of this study was to estimate the influence of corticosteroids on Th1 and Th2 serum cytokine balance in patients with GO: IFNgamma, TNFalpha, IL-4 and IL-10. Further, we tested the hypothesis of an up-regulation of Th2 immune response during successful treatment with corticosteroids to explain their beneficial effect in Graves' ophthalmopathy. Serum cytokines were detected in three groups of subjects: 20 patients with Graves' disease without ophthalmopathy (Gd), 16 patients with clinical symptoms of ophthalmopathy (GO) (CAS over 3 points, last consultation record for GO less than a year old) and 16 healthy volunteers. Corticosteroid therapy consisted of intravenous infusions of methylprednisolone (MP) (2 series, 3 g each time) and subsequent treatment with oral prednisone (60 mg per day) in a tapering schedule. The serum samples were collected 24 hours before MP, 24 hours after MP, 14 days of treatment with prednisone and at the end of corticosteroid therapy. The levels of IFNgamma, TNFalpha, IL-4 and IL-10 in the serum were determined using ELISA. Statistical significance was estimated by the Mann-Whitney U-test. Our findings show a deviation to systemic Th2 profile cytokines in Graves' disease. In patients with GO, we found a significantly increased serum IL-10 concentration. In corticosteroid-responsive patients, the balance of serum cytokines IL-4/IFNgamma, IL-4/TNFalpha, IL-10/IFNgamma and IL-10/TNFalpha increased and remained upregulated until the end of the study. In non-responders, the balance of serum cytokines studied increased after methylprednisolone but declined markedly during continuation of the therapy with prednisone. In summary, our results show that efficient corticosteroid therapy may be related to its influence on Th2/Th1 profile cytokine balance. The upregulation of serum IL-4 and IL-10 during successful treatment with corticosteroids indicate the possibility of using these cytokines as predictors of the beneficial effect of corticosteroids in Graves' ophthalmopathy.     

A tissue biomarker panel predicting systemic progression after PSA recurrence post-definitive prostate cancer therapy

Background

Many men develop a rising PSA after initial therapy for prostate cancer. While some of these men will develop a local or metastatic recurrence that warrants further therapy, others will have no evidence of disease progression. We hypothesized that an expression biomarker panel can predict which men with a rising PSA would benefit from further therapy.

Methodology/Principal Findings

A case-control design was used to test the association of gene expression with outcome. Systemic (SYS) progression cases were men post-prostatectomy who developed systemic progression within 5 years after PSA recurrence. PSA progression controls were matched men post-prostatectomy with PSA recurrence but no evidence of clinical progression within 5 years. Using expression arrays optimized for paraffin-embedded tissue RNA, 1021 cancer-related genes were evaluated–including 570 genes implicated in prostate cancer progression. Genes from 8 previously reported marker panels were included. A systemic progression model containing 17 genes was developed. This model generated an AUC of 0.88 (95% CI: 0.84–0.92). Similar AUCs were generated using 3 previously reported panels. In secondary analyses, the model predicted the endpoints of prostate cancer death (in SYS cases) and systemic progression beyond 5 years (in PSA controls) with hazard ratios 2.5 and 4.7, respectively (log-rank p-values of 0.0007 and 0.0005). Genes mapped to 8q24 were significantly enriched in the model.

Conclusions/Significance

Specific gene expression patterns are significantly associated with systemic progression after PSA recurrence. The measurement of gene expression pattern may be useful for determining which men may benefit from additional therapy after PSA recurrence.

Anti-inflammatory and surgical therapy of olfactory disorders related to sino-nasal disease

Olfactory loss may be caused by mechanical obstruction or inflammation of the olfactory epithelium due to allergic/non-allergic rhinitis and chronic sinusitis with or without polyps. Treatment of olfactory loss related to sino-nasal disease is possible. Apart from surgical approaches and/or treatment with antibiotics, both systemic and topical steroids are effectively used in the therapy of olfactory loss related to sino-nasal disease. In most cases improvement of olfactory function appears to relate to the anti-inflammatory actions of the steroids used. While some details of therapeutic effect and dose regimen are not clear, systemic steroids are often helpful even in patients without nasal obstruction due to polyps or obvious inflammatory changes.     

Steady-state mycophenolate mofetil pharmacokinetic parameters enable prediction of systemic lupus erythematosus clinical flares: an observational cohort study

Age-related diffuse chronic telogen effluvium- type alopecia in female squirrel monkeys (Saimiri boliviensis boliviensis)

We investigated the diffuse alopecia affecting some female squirrel monkeys (Saimiri boliviensis boliviensis) housed in a breeding facility. We randomly selected 100 female and 10 male animals and performed a complete physical exam and a hair assessment on all animals; blood tests, trichograms, hair density; and skin biopsies in representative cases; and a dominance behavioral assessment of 50 animals. Hair coat was normal in 35 female monkeys and all 10 male animals. Of the 65 females with diffuse alopecia, 17 had mild, 22 moderate, and 26 severe hair loss. The alopecia group had a mean age of 9.6 +/- 0.6 years, whereas that of the normal group was 4.7 +/- 0.6 years (P < 0.05). The parity in the alopecia group was 4.2 +/- 0.6 but 2.0 +/- 0.6 (P < 0.05) in the normal group. There were no statistically significant differences in body weight, hemoglobin, blood urea nitrogen, serum glucose, liver aspartate aminotransaminase, or free thyroxine. The trichogram demonstrated 20.8% +/- 1.6% (mean +/- standard error) of telogen hairs in the alopecia group compared with 9.5% +/- 2.8% of the control group (P < 0.05). The hair density in the alopecia group was 52.8 +/- 4.1/cm2 and 79.6 +/- 14.3/cm2 in the control group. Skin biopsies in affected monkeys demonstrated increased telogen follicles, with no fibrosis or inflammation. There were no statistically significant differences in the dominance behavioral analysis. The findings are consistent with chronic telogen effluvium (CTE). A number of organic, behavioral, and dominance-related stress causes of CTE were excluded. CTE appears to be predominantly age-related in this population. CTE in female squirrel monkeys may serve as an animal model for human diffuse alopecia.
