Geriatric dermatology is a specialty that is receiving particular attention. Among the other topics and diseases briefly covered here are dermatologic nursing home visits, decubitus ulcers, pruritus/xerosis, eczematous dermatitis, psychogenic dermatitides, infections of the skin, purpura, vascular compromise, chronic venous insufficiency, and bullous pemphigoid. Illnesses originating in other organ systems that are made manifest on the skin often complicate the diagnostic and therapeutic picture. Chronic diseases such as diabetes mellitus and HIV compound the problems in diagnosing and treating geriatric dermatologic diseases. Since the human population is living longer, chronic diseases will become more prevalent, as will diseases of the skin.

Two thousand patients who visited the outpatient department at the Institute of Dermatology, Bangkok, were assessed for the presence of foot diseases by questionnaire and physical examination. Abnormalities were detected in 741 individuals (37.1%). Nonfungal conditions were more prevalent (31.4%), mainly consisting of eczema (254 cases, 12.7%) and psoriasis (176 cases, 8.8%). Fungal disease was observed in 119 cases (6.0%). There were 76 cases (3.8%) with tinea pedis and 33 cases (1.7%) with onychomycosis. The identified organisms causing tinea pedis were 57.9% nondermatophyte moulds, 36.8% dermatophytes, and 2.6%Candida spp. The corresponding organisms causing onychomycosis were 51.6% nondermatophyte moulds, 36.3% dermatophytes, and 6.0%Candida spp. Among nondermatophytes, Scytalidium dimidiatum was the leading pathogen while Trichophyton rubrum and T. mentagrophytes were the predominant dermatophytes identified. Diabetes mellitus, peripheral vascular disease and activities related to foot trauma were noted to be predisposing factors for onychomycosis. Footwear, particularly sandals and cut shoes, was the only factor relevant to individuals with tinea pedis (P < or = 0.05). In contrast with other published data on fungal foot infections, this study disclosed a higher prevalence of nondermatophyte organisms, predominantly S. dimidiatum, as the major cause of tinea pedis and onychomycosis. An increase in awareness is necessary to identify such cases, prevent misdiagnosis and initiate appropriate treatment.

Since ancient times, plants and herbal preparations have been used as medicine. Research carried out in last few decades has certified several such claims of use of several plants of traditional medicine. Popularity of Momordica charantia (MC) in various systems of traditional medicine for several ailments (antidiabetic, abortifacient, anthelmintic, contraceptive, dysmenorrhea, eczema, emmenagogue, antimalarial, galactagogue, gout, jaundice, abdominal pain, kidney (stone), laxative, leprosy, leucorrhea, piles, pneumonia, psoriasis, purgative, rheumatism, fever and scabies) focused the investigator's attention on this plant. Over 100 studies using modern techniques have authenticated its use in diabetes and its complications (nephropathy, cataract, insulin resistance), as antibacterial as well as antiviral agent (including HIV infection), as anthelmintic and abortifacient. Traditionally it has also been used in treating peptic ulcers, interestingly in a recent experimental studies have exhibited its potential against Helicobacter pylori. Most importantly, the studies have shown its efficacy in various cancers (lymphoid leukemia, lymphoma, choriocarcinoma, melanoma, breast cancer, skin tumor, prostatic cancer, squamous carcinoma of tongue and larynx, human bladder carcinomas and Hodgkin's disease). There are few reports available on clinical use of MC in diabetes and cancer patients that have shown promising results.

A retrospective study of 232 elderly patients seen between August 1998 and April 2000 at the skin clinic in Princess Haya hospital, Aqaba, was undertaken to determine the prevalence of skin disorders, and those most commonly associated with diabetes mellitus, in the elderly. Eczema/dermatitis was the commonest skin disorder seen (25.9% of cases), followed by pruritus without skin lesions (15.1%), viral infection (14.7%, most commonly herpes zoster), fungal infection (13.8%), and bacterial infection (10.3%). Bacterial infection was the commonest skin disorder in patients with diabetes mellitus (62.5%), followed by fungal infection (50.0%). Skin diseases cause considerable morbidity in elderly people; health promotion and education can do much to reduce the risks of these disorders in the elderly, especially those with diabetes.

Gamma-linolenic acid (GLA, C18:3delta6 ,9,12), an essential polyunsaturated fatty acid, plays an important role in hormone regulation and fatty acid metabolization. Delta6-fatty acid desaturase (D6D) is the rate-limiting enzyme of the desaturation of linoleic acid (C18:2delta9,12) in the production of gamma-linolenic acid. A deficiency of GLA may have occurred when delta6-fatty acid desaturase activity decreases in aging, stress, diabetes, eczema, and some infections. To establish a new expression system for delta6-fatty acid desaturase gene in Pichia pastoris, which is an increasingly popular heterologous gene expression system, a gene encoding delta6-fatty acid desaturase from Mortieralla alpina was isolated by PCR amplification. The PCR product was then digested by EcoR I and Not I and subcloned into the intracellular expression vector pPIC3.5K to generate the recombinant vector pPIC3.5K-MA6. The resulting vector was linearized by Sac I and electroporated into P. pastoris SMD1168 (his- pep-) host cells. After electroporation, aliquots were spreaded on the MDS plates and incubated at 30 degrees C for three days until colonies appeared. Those transformants were subsequently screened for clones with high copy number by using the YPD plates containing G418. To identify the D6D constructs that were produced, chromosomal DNA of the transformants were prepared and used as template for PCR with the primer 5' AOX and 3' AOX. The PCR product of Mut+ recombinants was shown as a band of 1.38 kb of D6D gene and the product of 2.2 kb of AOX1 gene, while the product of Mut(s) transformants only was shown as a band of 1.38 kb of the D6D gene.To further confirm the transformants containing a functional D6D gene, the positive clones were selected and induced by methanol for expression. Those induced cultures were taken for analyses of the intracellular fatty acid composition by GC. The resultant chromatograms of fatty acid methyl esters showed that a novel peak was detected, which was not apparent in the case of control. Comparisons of the retention times of the newly yielded peaks with those of authentic standards have anticipated that the fatty acid is GLA. And this prospects was positively supported by definitive assignments of the compounds by GCMS analyses. Thus, the active delta6-fatty acid desaturase was expressed intracellularly in P. pastoris and gamma-linolenic acid reached 16.26% of the total fatty acid in recombinant P. pastoris strains. It was the first report about the expression of Mortieralla alpina D6D gene in P. pastoris.

Many endocrine diseases are accompanied by skin damage. It is induced by initial hormonal and metabolic disorders, manifestates at the early stage of the disease and represents very important diagnostic sign. Clinical peculiarities of diabetes mellitus dermal manifestations in children are presented in this review paper. Number of dermatosis are discussed which are mainly due to the disturbances of carbohydrate metabolism (skin itching, pioderma, candidosis, xanthochromia, eczema, psoriasis, necrobiosis lipoidica, granuloma annulare, xanthomatosis, black acanthosis, porphyria). Author suggests that during examination of children with different type of dermal pathology, dermatologist must suspect existence of diabetes mellitus and should investigate such cases for the presence of this disease. In other words, dermatologist can contribute in the early revelation of diabetes mellitus in children.

The misery of living with atopic eczema (syn. dermatitis, AD) cannot be overstated for it may have a profoundly negative effect on the health-related quality of life (HRQoL) of children and their family unit in many cases. As it is one of the commonest chronic relapsing childhood dermatosis (UK lifetime prevalence 16-20% by 20 years), with increasing worldwide prevalence, this has major social and financial implications for individuals, healthcare providers and society as a whole. This review explores the impact of AD on the lives of children and their family units and the use of some of the recently developed HRQoL measures, which have enabled investigation and categorisation of the physical, psychological and psycho-social effects of childhood eczema across all aspects of life. These effects include symptoms of itching and soreness, which cause sleeplessness in over 60%. Sleep deprivation leads to tiredness, mood changes and impaired psychosocial functioning of the child and family, particularly at school and work. Embarrassment, comments, teasing and bullying frequently cause social isolation and may lead to depression or school avoidance. The child's lifestyle is often limited, particularly in respect to clothing, holidays, staying with friends, owning pets, swimming or the ability to play or do sports. Restriction of normal family life, difficulties with complicated treatment regimes and increased work in caring for a child with eczema lead to parental exhaustion and feelings of hopelessness, guilt, anger and depression. The hidden costs involved in eczema management can be significant and have particular impact on lower income families. The impairment of quality of life caused by childhood eczema has been shown to be greater than or equal to other common childhood diseases such as asthma and diabetes, emphasising the importance of eczema as a major chronic childhood disease. HRQoL measures are proving to be valuable tools for use in the clinical setting, as outcome measures for pharmaceutical studies, for health economics and audit purposes. It is therefore recommended that in future, they should be used in conjunction with objective measures of severity, as part of the assessment process of a child with atopic eczema. Lack of information on eczema and treatments heightens parental anxiety. Education of all individuals involved in the care of children with eczema is fundamental in the management of AD and it is essential to provide simple clear, unambiguous information on treatment and disease management in order to reduce the negative impact on HRQoL.

Plant materials derived from the Aloe plant are used as cosmetic ingredients, including Aloe Andongensis Extract, Aloe Andongensis Leaf Juice, Aloe Arborescens Leaf Extract, Aloe Arborescens Leaf Juice, Aloe Arborescens Leaf Protoplasts, Aloe Barbadensis Flower Extract, Aloe Barbadensis Leaf, Aloe Barbadensis Leaf Extract, Aloe Barbadensis Leaf Juice, Aloe Barbadensis Leaf Polysaccharides, Aloe Barbadensis Leaf Water, Aloe Ferox Leaf Extract, Aloe Ferox Leaf Juice, and Aloe Ferox Leaf Juice Extract. These ingredients function primarily as skin-conditioning agents and are included in cosmetics only at low concentrations. The Aloe leaf consists of the pericyclic cells, found just below the plant's skin, and the inner central area of the leaf, i.e., the gel, which is used for cosmetic products. The pericyclic cells produce a bitter, yellow latex containing a number of anthraquinones, phototoxic compounds that are also gastrointestinal irritants responsible for cathartic effects. The gel contains polysaccharides, which can be acetylated, partially acetylated, or not acetylated. An industry established limit for anthraquinones in aloe-derived material for nonmedicinal use is 50 ppm or lower. Aloe-derived ingredients are used in a wide variety of cosmetic product types at concentrations of raw material that are 0.1% or less, although can be as high as 20%. The concentration of Aloe in the raw material also may vary from 100% to a low of 0.0005%. Oral administration of various anthraquinone components results in a rise in their blood concentrations, wide systemic distribution, accumulation in the liver and kidneys, and excretion in urine and feces; polysaccharide components are distributed systemically and metabolized into smaller molecules. aloe-derived material has fungicidal, antimicrobial, and antiviral activities, and has been effective in wound healing and infection treatment in animals. Aloe barbadensis (also known as Aloe vera)-derived ingredients were not toxic in acute oral studies using mice and rats. In parenteral studies, the LD(50) using mice was > 200 mg/kg, rats was > 50 mg/kg, and using dogs was > 50 mg/kg. In intravenous studies the LD(50) using mice was > 80 mg/kg, rats was > 15 mg/kg, and dogs was > 10 mg/kg. The 14-day no observed effect level (NOEL) for the Aloe polysaccharide, acemannan, in the diet of Sprague-Dawley rats, was 50,000 ppm or 4.1 to 4.6 g/kg day(-1). In a 3-month study using mice, Aloe vera (extracted in ethanol) given orally in drinking water at 100 mg/kg produced reproductive toxicity, inflammation, and mortality above that seen in control animals. Aloe vera extracted in methanol and given to mice at 100 mg/kg in drinking water for 3 months caused significant sperm damage compared to controls. Aloe barbadensis extracted with water and given to pregnant Charles Foster albino rats on gestational days (GDs) 0 through 9 was an abortifacient and produced skeletal abnormalities. Both negative and positive results were found in bacterial and mammalian cell genotoxicity assays using Aloe barbadensis-derived material, Aloe Ferox-derived material, and various anthraquinones derived from Aloe. Aloin (an anthraquinone) did not produce tumors when included in the feed of mice for 20 weeks, nor did aloin increase the incidence of colorectal tumors induced with 1,2-dimethylhydrazine. Aloe-emodin (an anthraquinone) given to mice in which tumor cells had been injected inhibited growth of malignant tumors. Other animal data also suggest that components of Aloe inhibit tumor growth and improve survival. Various in vitro assays also demonstrated anticarcinogenic activity of aloe-emodin. Diarrhea was the only adverse effect of note with the use of Aloe-derived ingredients to treat asthma, ischemic heart disease, diabetes, ulcers, skin disease, and cancer. Case reports include acute eczema, contact urticaria, and dermatitis in individuals who applied Aloe-derived ingredients topically. The Cosmetic Ingredient Review Expert Panel concluded that anthraquinone levels in the several Aloe Barbadensis extracts are well understood and can conform to the industry-established level of 50 ppm. Although the phototoxicity anthraquinone components of Aloe plants have been demonstrated, several clinical studies of preparations derived from Aloe barbadensis plants demonstrated no phototoxicity, confirming that the concentrations of anthraquinones in such preparations are too low to induce phototoxicity. The characterization of aloe-derived ingredients from other species is not clear. In the absence of well-characterized derivatives, biological studies of these materials are considered necessary. The studies needed are 28-day dermal toxicity studies on Aloe Andongensis Extract, Aloe Andongensis Leaf Juice, Aloe Arborescens Leaf Extract, Aloe Arborescens Leaf Juice, Aloe Ferox Leaf Extract, Aloe Ferox Leaf Juice, and Aloe Ferox Leaf Juice (ingredients should be tested at current use concentrations). In Aloe-derived ingredients used in cosmetics, regardless of species, anthraquinone levels should not exceed 50 ppm. The Cosmetic Ingredient Review Expert Panel advised the industry that the total polychlorobiphenyl (PCB)/pesticide contamination of any plant-derived cosmetic ingredient should be limited to not more than 40 ppm, with not more than 10 ppm for any specific residue and that limits were appropriate for the following impurities: arsenic (3 mg/kg maximum), heavy metals (20 mg/kg maximum), and lead (5 mg/kg maximum).

We report on a 6-month-old child presenting with chronic diarrhea, failure to thrive, eczema, autoimmune hemolytic anemia (AIHA), insulin-dependent diabetes mellitus (IDDM), hypoalbuminemia, and proteinuria. Renal biopsy showed membranous glomerulonephritis. A diagnosis of Immunodysregulation, polyendocrinopathy, enteropathy, x-linked (IPEX) syndrome was subsequently confirmed by DNA analysis, which demonstrated the presence of a mutation in exon 2 of the FOXP3 gene (303-304 del TT). Proteinuria secondary to membranous glomerulonephritis is a novel feature of IPEX syndrome. Membranous glomerulonephritis went into remission after the patient had received hematopoietic stem cell transplantation (HSCT).

Otitis externa, an inflammation of the external auditory canal is the most frequent cause of ENT consultation all over the world. It can be caused by viral, bacterial or fungal infections. In most of the cases it is provoked by anatomical causes and, even more frequently inadvertently, by the patient himself. Typically, otitis externa is an isolated episode of short duration, easily treated with topical medication. It evolves rarely to the atypical forms of chronic otitis externa and malignant otitis externa. It is important to search for an allergy, eczema or immunodepression in cases of chronic otitis externa and for diabetes in cases of malignant otitis externa.
