Forty-five patients entered this study. All patients had stage III or IV squamous cell carcinoma of the head and neck and had been treated with surgical resection, radiation, or both. All patients were then treated with bioadjuvant chemopreventive treatment for 12 months. We previously reported a 24-month median follow-up of this phase 2 trial of the combination of isotretinoin, interferon alfa-2a, and vitamin E as bioadjuvant therapy after definitive local therapy. In that study, all 45 patients completed treatment, but 1 patient was excluded from analysis of recurrence and development of second primary tumors. Main Outcome Measure Longer-term (49.4-month median) follow-up.

Previous studies have shown that propylene glycol causes inflammatory changes and cholesteatoma when applied to chinchilla middle ears. Vitamin A and synthetic analogues are essential for the normal differentiation of epithelial tissues. The purpose of this study was to determine whether the administration of isotretinoin to chinchillas would prevent propylene glycol exposure from inducing middle ear cholesteatomas. Sixteen chinchillas received 90% propylene glycol to the left middle ear and normal saline to the right. Half the animals were placed in the experimental group and received a daily dose of isotretinoin of 2 mg/kg for 7 days prior to propylene glycol administration and then for 6 weeks until killed. At 6 weeks, cholesteatoma was found in six of eight ears treated with propylene glycol in animals receiving isotretinoin. Two animals in the control group died. Three of the remaining eight had cholesteatoma. No ears treated with saline had cholesteatoma. We conclude that isotretinoin, in our chinchilla model, does not prevent propylene glycol-induced cholesteatoma formation.

Thirty studies of variable quality were included. Eight trials showed that topical tretinoin cream, in concentrations of 0.02% or higher, was superior to placebo for participants with mild to severe photodamage on the face and forearms (although losses to follow-up were relatively high in most studies). For example, the relative risk of improvement for 0.05% tretinoin cream, compared to placebo (three studies), at 24 weeks, was 1.73 (95% confidence interval 1.39 to 2.14). This effect was not seen for 0.001% topical tretinoin (one study) or 0.01% (three studies). A dose-response relationship was evident for both effectiveness and skin irritation. One small within-patient study showed benefit from topical ascorbic acid compared with placebo. Tazarotene (0.01% to 0.1%) and isotretinoin (0.1%) both showed significant improvement over placebo for moderate photodamage (one study each). There is limited evidence (one trial), to show that the effectiveness of 0.05% tretinoin, is equivalent to the effects of 0.05% and 0.1% tazarotene. One small study showed greater improvement in upper lip wrinkles with CO2 laser technique compared to Baker's phenol chemical peel, at 6 months. Three small RCTs comparing CO2 laser with dermabrasion found no difference in wrinkle score at 4 to 6 months, suggesting that both methods are equally efficacious, but more erythema was reported with the laser. The effectiveness of other interventions such as hydroxy acids and natural polysaccharides was not clear.

The purpose of the study was to evaluate the effect of a standard, single course of isotretinoin (Accutane) therapy on bone mineral density (BMD) of the lumbar spine and hip in adolescents ages 12 to 17 years with severe, recalcitrant, nodular acne.

Oral administration of isotretinoin (13-cis-retinoic acid) (6 mg/kg per day), 0.05% hexachlorobenzene (HCB) or both drugs simultaneously for 10 days to female Wistar rats caused a statistically significant induction of aminopyrine-N-demethylase (ADM), 7-ethoxyresorufin-O-deethylase (7-ERO-D) and erythromycin-N-demethylase (EMDM) in the liver microsomes. Oral administration of isotretinoin alone or together with HCB induced a marked induction of 7-ERO-D and EMDM in the skin. Administration of isotretinoin alone for 60 days resulted in the induction of EMDM in the liver microsomes, and in combination with HCB caused a statistically significant induction of all hepatic isozymes. HCB alone caused a marked induction of only 7-ERO-D in the skin. These results clearly show that oral isotretinoin is capable of inducing hepatic and cutaneous microsomal P-450-dependent catalytic activities. It remains to be elucidated whether the induction of these enzymes is of importance for the therapeutic action of isotretinoin.

A 31-year-old man ingested 1000 mg of tretinoin (100 pills of Vesanoid 10 mg) in a suicide attempt. He developed nonbloody diarrhea, but otherwise had no complaints. Clinical examination was normal. The patient was treated with activated charcoal and was hydrated. The patient's blood results did not show any deterioration on the third consecutive day. He was discharged well on the third day, but was subsequently lost to follow-up.

Photoaging is a cumulative degenerative process induced by solar irradiation with well defined clinical and histological correlates. Because of its huge psychological impact, there is much demand for effective treatment. Many well constructed trials confirm the clinical efficacy of topical tretinoin for improving fine wrinkling and mild to moderate hyperpigmentation; coarse wrinkling and severe hyperpigmentation respond less well. Histological improvement is well documented, but the precise relationship to clinical response is not clearly established. Tolerability can be a problem. Optimal concentrations are not firmly established and vary between patients. Claims that topical isotretinoin is better tolerated than tretinoin need to be confirmed with well constructed trials. Despite many claims, there have been no adequate trials documenting the efficacy of fish cartilage polysaccharide extracts or alpha-hydroxy acids. Careful patient selection with consideration of alternative treatments such as chemical peeling, dermabrasion and surgery is important to successful management of photoaging.

This investigation was undertaken to assess biological variation, especially the within-subject variations of all-trans retinoic acid, 13-cis retinoic acid and retinol in human serum. Diurnal variation and variation over a week, a month and a year were studied in 11 males (aged 21-54 years) and 17 females (aged 22-63 years), all subjectively healthy. We found no diurnal variation with the exception of all-trans retinoic acid, which had maximal concentrations at noon irrespective of food intake. Seasonal variations were marginal. Both all-trans and 13-cis retinoic acids had fairly high within-subject (13.1%, and 12.6%, respectively) and between-subject coefficients of variation (15.9% and 21.0%, respectively), while the within-subject CV of retinol was less (5.6%, with a between-subject CV of 21.1%). Thus, the indices of individuality were < 1 for all retinoids. The critical differences between two consecutive samples were < 40% for the retinoic acids and < 20% for retinol. Women had higher all-trans retinoic acid concentrations in serum (5.1 nmol/L vs. 4.5 nmol/L), lower 13-cis retinoic acid concentrations (4.5 nmol/L vs. 5.5 nmol/L) and lower retinol concentrations in serum (2.1 micromol/L vs. 2.5 micromol/L) than men. Thus, samples for retinoid determinations should be drawn in the morning and evaluated using separate gender reference intervals.

IGF-1 and IGFBP3 levels decreased significantly after treatment (P < 0.01), while GH levels did not change. Post-treatment, significant increases were seen in aspartate aminotransferase, total cholesterol, low-density lipoprotein cholesterol, triglycerides and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio (P < 0.0001) while high-density lipoprotein cholesterol levels were significantly decreased (P < 0.0001).

OMS is a rare paraneoplastic disorder that affects adults and children. Pediatric OMS is often associated with NB, a common, solid tumor of childhood, derived from the sympathetic nervous system. The detection of autoantibodies and lymphocytic infiltration in NB patients led to advance an autoimmune hypothesis for the pathogenesis of OMS-related NB. BAFF is a potent modulator of B cell growth and survival upon interaction with its receptors BAFF-R and BCMA. The aim of this study was to investigate mechanism(s) involved in ectopic lymphoid neogenesis in OMS-associated NB. We investigated BAFF, BAFF-R, and BCMA expression in NB tumors associated or not with OMS. Furthermore, we evaluated BAFF expression and secretion in NB cell lines, treated or untreated with differentiating agents. Immunohistochemically, lymphocytes infiltrating NB tumors from patients, with or without OMS, expressed BAFF, BAFF-R, and BCMA, whereas neuroblasts expressed BAFF and BCMA but not BAFF-R. By flow cytometry, BAFF was found to be consistently expressed in NB cell lines. Similarly to the results obtained in tissue lesions, BCMA but not BAFF-R was detected on the surface of all NB cell lines under basal conditions. De novo synthesis of BAFF-R and up-regulation of BCMA were observed in NB cell lines upon treatment with IFN-γ or 13-cis retinoic acid. This study provides new insights in the mechanisms driving the neogenesis of lymphoid follicles and in the functional interactions between tumor and immune cells in OMS-associated NB.

The addition of retinoic acid to human promyelocytic leukemia cells in culture results in their differentiation to mature myeloid forms with acquisition of the differentiated phenotype, i.e., the ability to reduce nitroblue tetrazolium. A heavily pretreated patient with acute promyelocytic leukemia and residual malignant cells in his marrow after multiple courses of chemotherapy was given 13-cis-retinoic acid upon demonstration of both morphologic and functional differentiation of his leukemic cells by transretinoic acid in vitro. The patient achieved a complete remission and was maintained on 13-cis-retinoic acid for 1 year, when the patient relapsed with a population of cells that were resistant to retinoic acid-induced differentiation.

The effect of two naturally occurring (retinol and all-trans retinoic acid) and two synthetic (isotretinoin and acitretin) analogs of vitamin A (retinoids) on tRNA biogenesis was investigated employing the RNase P of Dictyostelium discoideum as an in vitro experimental system. RNase P is an ubiquitous and essential enzyme that endonucleolytically cleaves all tRNA precursors to produce the mature 5' end. All retinoids tested revealed a dose-dependent inhibition of RNase P activity, indicating that these compounds may have a direct effect on tRNA biogenesis. Detailed kinetic analysis showed that all retinoids behave as classical competitive inhibitors. The Ki values determined were 1475 microM for retinol, 15 microM for all-trans retinoic acid, 20 microM for isotretinoin, and 8.0 microM for acitretin. On the basis of these values acitretin is a 184, 2.5, and 1.9 times more potent inhibitor, as compared with retinol, isotretinoin, and all-trans retinoic acid, respectively. Taking into account that retinoids share no structural similarities to precursor tRNA, it is suggested that their kinetic behavior reflects allosteric interactions of these compounds with hydrophobic site(s) of D. discoideum RNase P.

Adverse ocular reactions including dry eye symptoms and blepharoconjunctivitis are common side effects of treatment with isotretinoin (13-cis-retinoic acid). However, there is little agreement in the literature on the effect of this drug on the tears. Because we have previously shown that the lacrimal gland secretes isotretinoin, we conducted a study of the effect of isotretinoin on lacrimal gland function. Rabbits were treated with isotretinoin for 5 months. Throughout the study tear secretion was monitored by the Schirmer test. At the end of the study lacrimal gland function was assessed by measurement of fluid and protein secretion rates and secretion of retinol in response to a pilocarpine stimulus. Lacrimal gland function was not affected by isotretinoin as compared with a group of age-matched control rabbits; however, Schirmer test scores were significantly increased in the treated animals as compared with control values. We conclude that isotretinoin is not toxic to the lacrimal gland of rabbits. This suggests that ocular irritation in patients treated with isotretinoin is not caused by decreased tear secretion during therapy.

Both intermittent and continuous low-dose isotretinoin regimens are very well tolerated and effective as classical regimens in the treatment of moderate acne vulgaris. However, a continuous low-dose regimen seems to be slightly superior in terms of patients' compliance to the treatment and lower risk of relapse.

Hypercornification is an early feature of acne and usually precedes inflammation. It is associated with ductal hyperproliferation, and there are many controlling factors such as androgens, retinoids, sebum composition and cytokines. Cycling of normal follicles and of comedones may explain the natural resolution of comedones and, in the longer term, resolution of the disease itself. There is a need to tailor treatment according to comedonal type. Suboptimal therapy can often result from inappropriate assessments of comedones, especially microcomedones, sandpaper comedones, submarine comedones and macrocomedones. Macrocomedones can produce devastating acne flares, particularly if patients are inappropriately prescribed oral isotretinoin. Gentle cautery under topical local anaesthesia is a useful therapy in the treatment of such lesions. The newer retinoids and new formulations of all-trans-retinoic acid show a better benefit/risk ratio.

Isotretinoin (13-cis-retinoic acid) is one of the synthetic retinoids derived from vitamin A. Vitamin A derivatives demonstrate virucidal activity, both in vivo and in vitro. Isotretinoin has been used for the treatment of recurrent herpes simplex with encouraging results. However, we present a case with frequent attacks of herpes labialis during isotretinoin therapy for acne, who had a marked decrease in frequency of recurrences following strict use of sunscreens.

In a phase II clinical trial, we sought to buy accutane determine if combining celecoxib with 13-cis-retinoic acid (13-cRA, Accutane) was efficacious in the treatment of recurrent (progressive) glioblastoma multiforme (GBM). In parallel, we also sought to determine to what extent the outcomes from this clinical trial correlated with the findings from studies utilizing two murine intracerebral GBM models, U87MG and U251HF, to determine the predictive value of these murine models. In the clinical trial, 25 patients were studied at recurrence. Stable disease, which occurred in 44% of the patients, was the best response. The median progression-free survival (PFS) was 8 weeks, with a PFS at 6 months of only 19%. For the patients with stable disease, the median PFS was 24 weeks. The toxicity profile was unremarkable. The modest effect on PFS seen in this study agreed with the recent findings of another study, which showed a 19% PFS at 6 months in patients treated with 13-cRA alone. Thus, the combination of 13-cRA with celecoxib is not more effective than 13-cRA in the treatment of progressive GBM. In the murine model study, we found that long-term dosing with 13-cRA or celecoxib alone or in combination did not increase survival in animals with U87MG tumors but modestly increased survival in animals with U251HF tumors. There was no evidence of synergism between the two drugs. From this, we concluded that the animal studies generally predicted that the two agents would have only a modest effect alone and no additive effect when given in combination to patients.

We sought to evaluate the efficacy, biochemical effects, safety and outcome of recombinant human thyroid-stimulating hormone (rhTSH) as an adjunct to radioiodine treatment of advanced differentiated thyroid carcinoma (DTC). We also sought to determine whether rhTSH is useful as an adjunct to radioiodine treatment following isotretinoin re-differentiation therapy of DTC metastases that have lost function. Therefore, in 54 consecutive patients who had retained bulky metastatic and/or locoregional lesions of DTC despite the exhaustion of other therapeutic options, we gave one to four courses of two consecutive daily intramuscular injections of rhTSH, 0.9 mg, followed by a therapeutic activity of (131)I per os on day 3. Fifty patients had received prior radioiodine treatment aided by l-thyroxine (T(4)) withdrawal. We included in the study 23 patients who had received a trial of isotretinoin therapy for re-differentiation of confirmed de-differentiated metastases. In a blinded, within-patient comparison of post-therapy whole-body scans after the first rhTSH-aided and latest withdrawal-aided treatments in patients with functional metastases at baseline, 18 of 27 (67%) scan pairs were concordant, four (15%) were discordant in favour of the rhTSH-aided scan and five (19%) were discordant in favour of the withdrawal-aided scan. In total, 37 (74%) of 50 paired scans were concordant, eight (16%) favoured rhTSH and five (10%) favoured withdrawal. All differences appeared to be attributable to clinical causes, not to any difference between endogenous and exogenous TSH stimulation. Reflecting the biochemical activity of rhTSH and the release of thyroglobulin (Tg) due to tumour destruction, median serum Tg concentration rose approximately fourfold between baseline and day 6 of the rhTSH-aided treatment course. rhTSH was well tolerated, with mostly minor, transient toxicity, except for neck oedema in three patients with neck infiltrates and pathological spine fracture in one patient with a large vertebral metastasis. At 6 months, complete response occurred in one (2%), partial response in 12 (26%) and disease stabilisation in 19 (40%) of 47 evaluable patients. The rate of complete + partial response was 41% and that of disease stabilisation, 30%, in the 27 evaluable patients with functional metastases at baseline; the corresponding rates were 10% and 55% in the 20 evaluable patients with non-functional metastases at baseline. Although within-patient comparison of early outcome after both modalities is limited by a significantly greater median number of courses and a greater median cumulative activity of radioiodine given under withdrawal, response to rhTSH-aided and withdrawal-aided treatment was similar in 23 (52%) of 44 evaluable patients, superior with rhTSH in 12 (27%) and superior with withdrawal in seven (16%). In two patients, a superior response was obtained after isotretinoin pretreatment and rhTSH and attributed to re-differentiation therapy. In conclusion, our study provides preliminary evidence that rhTSH Flomax Dosage Directions safely and effectively aids radioiodine treatment of advanced DTC, and does so to an at least equivalent degree as does T(4) withdrawal.

Among the 45 patients treated under Zyrtec Off Brand the protocol, only 7 patients (16%) had died. Nine (20%) of 45 patients experienced progressive disease. Only 1 second primary tumor (acute promyelocytic leukemia) occurred during follow-up, and no aerodigestive second primary tumors occurred among the 45 patients. The 5-year progression-free survival and overall survival percentages were 80% (95% confidence interval, 65.1%-89.1%) and 81.3% (95% confidence interval, 63.7%-90.9%), respectively. These results are significantly better than the historical 5-year overall survival for advanced squamous cell carcinoma of the head and neck (approximately 40%).

After studying the information in this article, the reader should be able to: 1. Describe the purpose of the pregnancy prevention program. 2. Discuss the five most common reasons for unintended pregnancy. 3. List the components of the expanded pregnancy prevention program. Preventing unintended pregnancy is currently an unsolved problem in the United States, especially among teens. However, successful programs to minimize unintended pregnancy do exist and can serve as a model for other efforts. One such program is the Pregnancy Prevention Program, for use when prescribing isotretinoin to women with childbearing potential. Isotretinoin is a known teratogen and is prescribed disproportionately to teens, who are at higher risk of unintended pregnancy. The Topamax Reviews Migraine program has shown impressive effectiveness despite these handicaps, but since exposure to isotretinoin is so harmful to the fetus and some women still become pregnant while taking the drug, the program has been revised to reduce the failure rate further.

Previous observations have indicated that isotretinoin (IT), a drug in common use for therapy of cystic acne, is teratogenic in humans but possesses low embryotoxicity in pregnant mice, probably because of its shorter half-life and limited placental transfer in rodents. In human volunteers and patients, one major blood metabolite of IT is 4-oxo-isotretinoin (4-oxo-IT) which undergoes slower elimination than IT and may itself be a participant in teratogenesis. To investigate the problem of species differences displayed by IT and the role of its metabolism, embryotoxic effects of 4-oxo-IT were examined after its single or repeated intubations into pregnant ICR mice and compared with the effects of a similar regimen of IT. The two compounds were also tested for their relative ability to suppress chrondrogenesis in the in vitro cell and organ culture assays. We found that a single dose of 4-oxo-IT, 100 mg/kg, given on day 11 of gestation (plug day = day 0 of gestation) produced a moderate incidence of limb reduction defects and cleft palate (39% and Buspar Online 27% of surviving fetuses, respectively), while a dose of 150 mg/kg affected virtually every fetus. IT, on the other hand, produced no defects in fetuses exposed to similar dose levels. Repeated intubations with IT, however, resulted in increasing the frequencies of limb reduction defects and cleft palate to levels obtained after 4-oxo-IT administration. We found that a 3-hour interval between IT intubations was more effective in this regard than an 8-hour interval. Repeated IT intubations also uncovered sharper stage-dependency of limb and palatal defects than obtained otherwise.(ABSTRACT TRUNCATED AT 250 WORDS)

In healthy individuals, we isolated microsomal fractions from the epidermis of Epivir Drug keratome biopsy specimens and measured CYP26 enzymatic activity in untreated skin and skin treated with tRA. Enzymatic activity was determined based on rate of formation of 4-hydroxy RA (pg/min/mg microsomal protein). Using real-time polymerase chain reaction we quantified CYP26 messenger RNA induction after tRA application in patients with acne who responded or did not respond to one course of 13-cis RA.

Lithium continues to increase the incidence of multiple cutaneous lesions among BPAD patients on lithium therapy. Incidence of cutaneous side effects directly correlates with the dose of lithium and therapeutic range of serum lithium level. Altering the dose of lithium does not statistically influence the cutaneous lesion.

Propionibacterium acnes reside within the pilosebaceous unit in a biofilm. As such, they live in a community of bacteria that encase themselves within an extracellular polysaccharide lining, which the organisms secrete after adherence to the surface. This gylcocalyx polymer acts as a protective exoskeleton and serves as a physical barrier, limiting effective antimicrobial concentrations within the biofilm microenvironment. The gylcocalyx polymer secreted by P. acnes as a biofilm may explain the immunogenicity of the organism as well as the clinical course of the disease. The P. acnes' biofilm model explains many aspects of acne pathogenesis and therapy, including why prolonged antibiotic treatment is needed, why antibiotic resistance is not a reliable assessment of treatment outcome, why accutane offers long-lasting effectiveness, and why benzoyl peroxide radicals are beneficial. This microbiologic principle of biofilms as applied to acne leads to numerous new pathways of assessment and exploration.

Oral, intraportal, iv doses of isotretinoin were administered to dogs before and after bile duct cannulation to determine the effect of route of administration and biliary excretion on the pharmacokinetics of this compound. Blood and bile samples were collected and analyzed for isotretinoin using a gradient elution high performance liquid chromatographic method. Blood concentrations were decreased after bile duct cannulation. Decreases in the area under the blood concentration-time curves were greatest following oral dosing, intermediate following intraportal dosing, and least following iv dosing. These results indicate that biliary excretion impacts on the blood profile of isotretinoin as a function of route of administration and that the differences are the result of differences in first pass clearance. In addition, the apparent bioavailability of isotretinoin was 14% in bile cannulated dogs and 54% in the intact (uncannulated) animals, suggesting that enterohepatic recycling of isotretinoin may contribute to its oral bioavailability. Isotretinoin was excreted in the bile; predominantly as a conjugate. The largest percentage (approximately 27%) of the dose was excreted in the bile following intraportal infusion, an intermediate percentage (approximately 8.5%) after iv dosing, and the smallest percentage (approximately 3.3%) after oral dosing. When the amount of drug excreted in bile as intact drug and conjugate is divided by the area under the systemic blood concentration--time curve, the resulting apparent biliary clearances following oral and intraportal administration were almost identical whereas the apparent biliary clearance after iv dosing was substantially less.(ABSTRACT TRUNCATED AT 250 WORDS)
