Tinea versicolor is a fungal infection of the skin caused by Malassezia species yeasts that normally live on the skin. It presents as scaly oval or round macules that often coalesce into irregular patches that vary in color. Diagnosis is made by visualizing the characteristic fungal elements using a potassium hydroxide preparation or potassium hydroxide-stained skin scraping under a microscope. Treatment involves topical antifungal medications. Regular use of topical agents helps reduce high recurrence rates.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

3. Tinea versicolor is a fungal
infection of the skin caused by
the yeast Pityrosporum orbiculare
(Malassezia furfur), a commensal
lipophilic fungus that lives in the
hair follicles and stratum
corneum.
01. DEFINITION
4. • The infection occurs more frequently
in regions with higher temperatures
and relative humidity
• Incidence of tinea versicolor is the
same in all races, but the eruption is
often more apparent in
darkerskinned individuals due to
resulting alteration in skin
pigmentation
• No sex predominance is apparent.
• Tinea versicolor is most common
among adolescents and young
adults, in whom lipid-producing
sebaceous glands are more active.
02. EPIDEMIOLOGY
9. Clinical Findings
The typical presentation of tinea versicolor is
scaly oval to round macules scattered over
characteristic areas of the body, including
the upper trunk, neck, and upper arms.
The macules often coalesce forming irregular
shaped patches of pigmentary alteration.
The color of patches varies from almost
white to
pink to reddish brown or fawn colored
10. Clinical Findings
Patches may have a wrinkled surface
appearance and this feature serves as a
useful clinical pearl for the diagnosis
11. DIAGNOSIS
The diagnosis made on clinical grounds is supported
by Wood's light examination which may show
yellow–orange fluorescence thought to be due to
the presence of pteridine and is confirmed by
microscopic KOH examination of the scale.
12. LAB.TEST
Potassium hydroxide (KOH) preparation of skin
scrapings demonstrates the characteristic fungal
spores and
short cigar-butt hyphae (“spaghetti and meatballs”)
Visualization of fungal elements may be enhanced
by the addition of methylene blue stain to the KOH
preparation
Culture is rarely necessary and requires a
lipid-containing medium (i.e., olive oil) to
demonstrate
growth.
13.
14. PREVENTION
05
Recurrence is common and regular maintenance application of any of the topical agents
helps to reduce high rates of recurrence.
While the condition does not leave any permanent scar or pigmentary changes, skin tone
may take several months to return to normal.
A regimen of one tablet a month of ketoconazole, fluconazole, and itraconazole has been
used successfully to prevent recurrences
16. Pityriasis alba
Pityriasis alba is a common disorder that is
characterized by an asymptomatic, hypopigmented,
slightly elevated, fine, scaling plaque with indistinct
borders.
The condition, which affects the face, lateral upper
arms , and thighs , appears in young children and
usually disappears by early adulthood.
17. Pityriasis Rosea
The typical eruption begins with the appearance of
one or multiple “herald patches”, which are large,
isolated, oval lesions, usually pink in color and
slightly scaly; they may occur anywhere on the body.
On occasion, the herald patch clears centrally,
mimicking tinea corporis.
From 5 to 10 days later, other smaller oval lesions
appear on the body, frequently concentrated over
the trunk but also seen on the proximal extremities,
especially the thighs
18. DIFFERENTIAL DIAGNOSIS
In adults, the white spots of tinea versicolor are most often Misdiagnosed as vitiligo . In
vitiligo, absence of scale and complete depigmentation are distinguishing factors from
tinea versicolor.
Tinea versicolor appearing as pink or tan scaling patches on the chest may be
misdiagnosed as seborrheic dermatitis . The distribution of seborrheic dermatitis involves
the hairline, eyebrows, nasolabial folds, and mid chest.
