Central chorioretinopathy is associated with the use of minoxidil 2percent for androgenetic alopecia.
Minoxidil appears to lengthen the duration of the anagen phase, and it may increase the blood supply to the follicle, even though the method of action is essentially unknown. Regrowth is more pronounced at the vertex than in the frontal areas and ain’t noted for at least 4 months. Continuing topical treatment with the drug is necessary indefinitely being that discontinuation of treatment produces a rapid reversion to the pretreatment balding pattern. 1 month after cessation of the drug, normal findings were found upon reexamination.
Hundreds of image rich slideshow presentations visually engage and challenge readers while expanding their knowledge of both common and uncommon diseases, case presentations, and current controversies in medicine. Only 2 drugs currently have US Food and Drug Administration -approved indications for treatment of androgenetic alopecia.
Dawson et al, while discussing female androgenetic alopecia, list the following treatment options to arrest hair loss progression and stimulate partial hair regrowth in this disorder.
These treatment are most effective when instituted early. More than 1000 clinical procedure articles provide clear, stepbystep instructions and include instructional videos and images to allow clinicians to master the newest techniques or to improve their skills in procedures they have performed previously.
Japanese study of 3177 men noted the efficacy and safety of finasteride in the treatment of androgenetic alopecia.
Adverse effects occurred in 7 of the men, and there were no safety problems observed with longterm use. Of these men, 111percentage showed great regrowth, 365percent moderate growth, and 395percent had a slight increase in hair growth. Did you hear about something like this before, is that the case? The authors concluded that in Japanese men with androgenetic alopecia, long time use of oral finasteride maintained progressive hair regrowth without recognized adverse effects. So, photographs were assessed in 2561 men who completed the ’42month’ study.
South Korean study noted the effect of a ‘1550 nm’ fractional ‘erbiumglass’ laser in women with androgenetic alopecia. It’s fairly obvious that this approval refers to safety rather than actual efficacy and that the data required for medical devices are quite different from those required to demonstrate the safety and efficacy of drugs. In a double blind, ‘shamdevice’ controlled, multicenter, ’26week’ trial, 110 patients in the active treatment group who completed the study showed a significantly greater improvement in overall hair regrowth than did the sham group. Normally, marketed as the HairMax LaserComb, it has obtained 510K FDA approval for use as a medical device. Just think for a moment. Lowlevel laser light therapy, especially a light red light hairbrushlike device was marketed as an overthecounter technique for hair growth. Patients received 10 treatments at 2week intervals. That said, global photographs taken at baseline and right after laser treatment showed improvement in 24 of the 27 patients studied. As a result, 2 patients reported mild pruritus after treatment.
BlumePeytavi’ U, Lönnfors S, Hillmann K, Garcia Bartels A randomized double blind placebo controlled pilot study to assess the efficacy of a 24 week topical treatment by latanoprost 1percent on hair growth and pigmentation in healthy volunteers with androgenetic alopecia.
Statistically significant increase in total hair count continued to be seen, just after 1 year. You see, aug 27 A phase 1, doubleblind clinical trial designed to evaluate the safety of a bioengineered, nonrecombinant, human ‘cell derived’ formulation containing follistatin, keratinocyte growth factor, and vascular endothelial growth factor was performed to assess the efficacy in stimulating hair growth. You see, twenty six subjects were entered into the study and none showed an adverse reaction to the single intradermal injection. Am Acad Dermatol.
More than 100 anatomy articles feature clinical images and diagrams of the human body’s major systems and organs. By the way, the medication was shown to increase regrowth in the frontal area as well, it affects vertex balding more than frontal hair loss. That said, they can also facilitate physician patient discussions. Articles assist in the understanding of the anatomy involved in treating specific conditions and performing procedures. Finasteride must be continued indefinitely being that discontinuation results in gradual progression of the disorder.
Patients who respond best to this drug are those who have a recent onset of androgenetic alopecia and small areas of hair loss. Findings indicated that 45percentage more regrowth occurred with the 5percent compared with the 2percent solution. For example, the drug is marketed as a 2 or a 5percent solution with the 5percent solution being somewhat more effective,. With that said, subsequent studies have shown at best a modest advantage to the higher concentration in women. Although, the increase in effectiveness of the 5 solution was not evident for women in the ‘FDAcontrolled’ studies. Women respond better to topical minoxidil than men. Occurrence of facial hair growth appears to be increased with the use of the higherconcentration formulation.
More than 6000 ‘evidencebased’ and physician reviewed disease and condition articles are organized to rapidly and comprehensively answer clinical questions and to provide indepth information in support of diagnosis, treatment, and similar clinical decisionmaking.
It ain’t an antiandrogen. Finasteride is given orally and is a ‘5 alpha’ reductase type 2 inhibitor. Remember, finasteride was shown to diminish the progression of androgenetic alopecia in males who are treated, and, in many patients, it has stimulated new regrowth. Basically the drug can be used only in men being that it can produce ambiguous genitalia in a developing male fetus. Essentially, topics are richly illustrated with more than 40000 clinical photos, videos, diagrams, and radiographic images.
Topical latanoprost 1percentage, a prostaglandin analogue used to treat glaucoma, is noted to cause an increase in the number, length, and thickness of eyelashes.
At 24 weeks, an increase in hair density was noted at the latanoprosttreated site compared with baseline and the placebo site. For instance, they applied latanoprost 1percent and placebo daily on 2 minizones on the scalp. Blume Peytavi et al conducted a 24 week topical treatment with this agent to note the effect on androgenetic alopecia. They concluded that this medication going to be useful for stimulating hair follicle activity and treating hair loss. Measurements of the hair growth, density, diameter, pigmentation, and anagen/telogen ratio were performed throughout the study. Sixteen young men with mild androgenetic alopecia were studied.
Adiposederived stem cells secrete various growth factors that promote hair growth. No adverse effects were noted in most of the patients. Actually, it was their impression that combination therapy was preferable to single agent treatment. Spain indicated that plasma rich in growth factors is effective in the treatment of androgenetic alopecia. Now look, the studies were done on patients both on and off finasteride. They think that using adiposederived stem cell‒conditioned medium seems to represent a new avenue of therapy for hair regeneration, and they reckon that longterm use gonna be studied to note effects and histological changes. Seriously. Using trichograms, Fukuoka and Suga evaluated the effects of ‘adipose derived’ stem cell‒conditioned medium on hair regeneration. Anagen follicles significantly increased by 2 compared with baseline, and there was a decrease of 1percent seen in telogen follicles. Then again, nearly any 4 weeks.
Interestingly, the efficacy of the medication was not reduced with time, and in had been successfully performed for the past 4 decades. Then the main problem is covering the bald area with donor plugs sufficient in number to be effective, the cosmetic results are often satisfactory. Micrografting produces a more natural appearance than the old technique of transplanting plugs.
Patients with less than 40 follicular units/cm2 in their donor areas are poor candidates for the procedure.
Cases of telogen effluvium often occur in patients with underlying androgenetic alopecia. Then, a search for treatable causes of telogen effluvium, especially in patients with an abrupt onset or a rapid progression of their disease, is indicated. This is the case. Scalp reduction is attempted to decrease the size of the scalp to be covered by transplanted hair, not surprisingly, it may accompany other forms of hair loss, Androgenetic alopecia is very common. Oftentimes the scars produced by the reduction technique often spread and become more noticeable with time.
