Although there are many potential changes of pharmacokinetic parameters in patients with thermal injury, obesity or septicemia, data about the actual effect on pharmacokinetics and clinical efficacy of fluconazole are very limited. As current dosing recommendations are derived from healthy subjects and patients with normal weight, these recommendations may be inaccurate when applied to the patient populations mentioned above. Pharmacokinetic data of 14 patients with thermal injury were reviewed and revealed a shorter half life and more rapid clearance of fluconazole. In a subgroup of five patients, distribution volume was up to 2 times larger as usual with no relationship to creatinine clearance and degree of burns. In one extremely obese patient treated with fluconazole 1200 mg/day, the corresponding mean steady-state plasma concentration and AUC were decreased with an increase of fluconazole clearance possibly due to a larger volume of distribution. In patients with septicemia, fluconazole plasma levels appear to be highly variable. As a considerable number of these patients develops acute renal failure, renal replacement therapy may be indicated which may require substantial dosage modifications of fluconazole.

An increase in the mycotic infections has been observed in recent decades. It is the effect of the development of industry, large migrations, living in huge aglomerations, usage of the public swimming-pools, wearing impervious clothes and shoes. Systemic diseases: diabetes, obesity, hormonal disorders, immune and food deficiency, AIDS, neoplasms and prescription drugs: antibiotics, corticosteroids and immunosuppressants, cause mycoses. Mycoses belong to chronic diseases, they are difficult to treat and very often recur. A lot of antimycotic drugs are known, but the most effective are azoles and alliloamines. An intensive research is conducted on introduction of new and more effective and cheaper preparations.

Tinea cruris is an intensely pruritic fungal infection of the groin and adjacent skin. Also known as crotch rot and jock itch, it can be a troubling important entity that at times is a clinical, diagnostic, and therapeutic challenge. Predisposing factors include heat, humidity, and hyperhidrosis, common accompaniments of high school-aged athletes. Furthermore, obesity and diabetes mellitus, additional risk factors for tinea cruris, are reaching unprecedented levels in adolescents. Treatment options range from improving hygiene to topical antifungal agents and systemic antifungal agents, the latter with potentially dangerous side effects.

A 34-year-old man with obesity who was an avid consumer of soft drinks was found in a coma after complaining of a poor physical condition for a few days. On arrival, he had hyperglycemia of 2700 mg/dL, coma, shock, sepsis, aspiration pneumonia, acute renal failure, acute pancreatitis, liver dysfunction, and systemic mycosis. The rapid infusion of a large volume of isotonic saline, insulin, antibiotics, and ulinastatin was performed, and mechanical ventilation was applied. The treatment was complicated by transient hypernatremia resulting from osmostasis, which gradually decreased. He demonstrated transient decerebrate posturing upon stimulation; however, he became conscious within a week of admission, and his associated diseases also improved. After correcting his hyperglycemia, the patient was discharged on foot. We report our case of a patient with hyperglycemia of 2700 mg/dL, which was the highest value reported in the English literature. During the correction of the hyperglycemia, transient hypernatremia occurred to prevent abrupt decrease in osmolality, which thus resulted in cell swelling.

Asthma is a common chronic disease characterized by intermittent chest symptoms, variable airways obstruction, and bronchial hyperresponsiveness. Research performed over the past one to two decades has sought to better understand the heterogeneous clinical nature of asthma. Whereas older attempts at phenotyping asthma emphasized the duality of allergic vs. non-allergic asthma, more recent non-biased analyses have attempted to cluster patients by a multitude of possible features, including age of onset, atopy, severity of airways obstruction, and requirement for medication. Examples of these phenotypes include early-onset mild allergic asthma, later-onset asthma associated with obesity, and severe non-atopic asthma with frequent exacerbations. The elucidation of asthma phenotypes has been further refined by including information regarding pathophysiologic mechanisms present in different groups. These groups, called endotypes, include examples such as aspirin-exacerbated respiratory disease and allergic bronchopulmonary mycosis. A growing understanding of these mechanistically distinct groups, along with the identification of relevant cellular or molecular biomarkers, is already showing promise as a way of predicting clinical response to various asthma therapies. As the number of targeted treatments for asthma continues to grow, physicians will have the opportunity to practice an individualized approach to diagnosis and treatment, which will hopefully improve asthma outcomes and quality of life for these patients.

Obesity in children is a major public health concern in the United States. The objectives of the current study were to determine the prevalence of various groups of cutaneous disorders in obese children and adolescents and to compare the use of dermatology services in obese subjects with that those with a normal body mass index (BMI). This was a retrospective, population-based study at the Kaiser Permanente Northern California Managed Healthcare System. The main outcome measures were the relative risk of cutaneous disorders associated with insulin resistance, androgen excess, bacterial infection, fungal infection, viral infection, inflammation, mechanical changes, and other skin conditions (hidradenitis, hyperhidrosis) in three weight groups (normal, overweight, obese) and the number of dermatology visits. A total of 248,775 subjects were included. Bivariate analyses showed a higher proportion of insulin resistance disorders, bacterial infection, fungal infection, inflammatory disorders, mechanical changes, and other skin conditions in obese subjects than in subjects with a normal BMI (p < 0.001). Disorders of androgen excess and viral infection were significantly less common in obese subjects (p < 0.001). Obese subjects had significantly lower odds of having at least one dermatology encounter than subjects with a normal BMI (odds ratio = 0.92, 95% confidence interval 0.88, 0.96, p = 0.003). Early onset obesity is associated with cutaneous disorders characterized by hyperproliferation, inflammation, bacterial and fungal infection, and mechanical changes but lower rates of disorders of androgen excess and viral infection. The use of dermatology services was not greater in obese patients. Heightened recognition and further analysis of adipose tissue as an endocrine organ that is capable of affecting the skin is warranted.

Recent literature data suggests that parasitic and fungal diseases, which pose a threat to both human and animal health, remain a clinical, diagnostic and therapeutic problem. Attention is increasingly paid to the role played by natural microbiota in maintaining homeostasis in humans. A particular emphasis is placed on the possibility of manipulating the human microbiota (permanent, transient, pathogenic) and macrobiota (e.g., Trichuris suis) to support the treatment of selected diseases such as Crohn's disease, obesity, diabetes and cancer. Emphasis is placed on important medical species whose infections not only impair health but can also be life threatening, such as Plasmodium falciparum, Echinococcus multilocularis and Baylisascaris procyonis, which expand into areas which have so far been uninhabited. This article also presents the epidemiology, diagnosis and treatment of opportunistic parasitoses imported from the tropics, which spread across large groups of people through human-to-human transmission (Enterobius vermicularis, Sarcoptes scabiei). It also discusses the problem of environmentally-conditioned parasitoses, particularly their etiological factors associated with food contaminated with invasive forms (Trichinella sp., Toxoplasma gondii). The analysis also concerns the presence of developmental forms of geohelminths (Toxocara sp.) and ectoparasites (ticks), which are vectors of serious human diseases (Lyme borreliosis, anaplasmosis, babesiosis), in the environment. Mycological topics contains rare cases of mycoses environmentally conditioned (CNS aspergillosis) and transmissions of these pathogens in a population of hospitalized individuals, as well as seeking new methods used to treat mycoses.

Onychomycosis accounts for 50% of all nail disease cases and is commonly caused by dermatophytes. Diabetes, human immunodeficiency virus, immunosuppression, obesity, smoking, and advancing age are predisposing factors of this fungal infection. Potassium hydroxide and culture are considered the current standard for diagnosing onychomycosis, revealing both fungal viability and species identification. Other diagnostic tests currently available include periodic acid-Schiff staining, polymerase chain reaction techniques, and fluorescent staining. Across 6 recently published epidemiology studies, the global prevalence of onychomycosis was estimated to be 5.5%, falling within the range of previously reported estimates (2%-8%). Newly approved onychomycosis treatments include efinaconazole, tavaborole, and laser therapy with lasers only approved to temporarily increase the amount of clear nail. Additional onychomycosis treatments being investigated include iontophoresis and photodynamic therapy with small open-label studies reported thus far. Preventative strategies, to help decrease recurrence and reinfection rates, include sanitisation of footwear and prophylactic topical antifungal agents.

Dermatologists must be familiar with the peculiarities of the micro-organisms that may affect the elderly, in order to optimize the diagnosis and treatment of infections, which may affect their skin, especially because the world population is rapidly aging. It is estimated that there will be 434 million individuals over 80 years of age in 2050. Since the elderly population is rapidly increasing and their infections are usually more severe and different from those observed in younger adults, it leads to a statistical increase of the rates regarding hospitalization and mortality caused by infectious diseases among people over 85 years. Other health issues may be involved in the older population. These include nutritional alterations, as malnutrition or obesity, which can aggravate the infections. Also the usual signs and symptoms of infection are subtle or uncharacteristic in elderly patients, and frequently, they are unable to report their symptoms, which can delay the diagnosis. Among the many infections that may affect the elderly we reviewed the most frequent and those that are different in this age group, as herpes zoster, cytomegalovirus, herpes simplex, bacterial skin infections, erysipelas, celullitis, impetigo, folliculitis, furunculosis and carbunculosis, secondary infections, intertrigo (body folds), fungal infection, and scabies.
