Occupational skin cancer and precancerous lesions are skin disorders caused by exposure to chemical carcinogens such as polycyclic hydrocarbons and arsenic, or radiation, such as ultraviolet light and ionizing light in the workplace. Annual increase in skin cancer incidence is believed to be related to various factors such as frequent intense sunlight exposure (i.e. at work, recreational activities, and sun-tanning habit), ozone depletion, an increase in number of geriatric population, and an increase of public awareness in skin cancer. The most common occupational skin cancers are basal cell carcinoma, squamous cell carcinoma, and melanoma. Examples of occupational precancerous lesion of the skin are actinic keratosis and Bowen’s disease. Particular diagnostic criteria to diagnose occupational diseases has been developed. Early detection of occupational skin cancer and precancerous lesion is necessary. An effective prevention program consists of primary prevention such as prevention of hazardous material exposure, secondary prevention such as early detection of disease for early intervention, and tertiary prevention such as minimizing long-term impact of the disease.

The human vagina together with its resident, microbiota, comprise a dynamic ecosystem. Normal microbiota is dominated by Lactobacillus species, and pathogen microbiota such as Gardnerella species and Bacteroides species can occur due to decrease in Lactobacillus domination. Lactobacillus plays an essential role in keeping normal vaginal microbiota in balance. Vaginal microbiota adapts to pH change and hormonal value. Changes in the vaginal microbiota over a woman’s lifespan will influence the colonization of pathogenic microbes. They include changes in child, puberty, reproductive state, menopause, and postmenopause. Estrogen levels change will affect the colonization of pathogenic microbium, leading to genitourinary syndrome of menopause. Vulvovaginal atrophy is often found in postmenopausal women, and dominated by L. iners, Anaerococcus sp, Peptoniphilus sp, Prevotella sp, and Streptococcus sp. The normal vaginal microbiota’s imbalance in menopause will cause diseases such as bacterial vaginosis, and recurrent vulvovaginal candidiasis due to hormonal therapies. Changes in the vaginal microbiota due to bacterial vaginosis are characterized by decrease in H2O2-producing Lactobacillus. They are also caused by the increase in numbers and concentration of Gardnerella vaginalis, Mycoplasma hominis, and other anaerob species such as Peptostreptococci, Prevotella spp, and Mobiluncus spp.

Papuloerythroderma (PE) is a rare skin disease which was first described by Ofuji et al. in 1984, with a typical sign that the lesions spare the large cutaneous folds, known as the deck chair sign. Due to its recent identification, this disease is still underrecognized and may lead to misdiagnosis. We reported the first case report of PE of Ofuji from Indonesia in which the diagnosis was delayed for two years. Besides the deck chair sign in the large cutaneous fold, we also found that the area between and above his eyebrows that was relatively spared in contrast to the sparing of the cutaneous folds, and it may be considered as pseudo-deck chair sign. The patient showed good response with combination therapy of phototherapy with Narrow-Band Ultraviolet B (NBUVB), oral methotrexate, and corticosteroids. The deck chair sign disappeared after six months therapy, but the patient’s skin was still xerotic.

Neural leprosy is characterized by neurological deficit without skin lesions, with a prevalence ranging from 1% to 17.7%. Diagnosis might be difficult and need a multidisciplinary approach. This is a case of axonal type motor and sensory polyradiculoneuropathy of the peripheral facial nerve. A 26-year-old woman was referred from the neurology clinic with facial paralysis, suspected as leprosy. Physical examinations were as follows: no skin lesions, left eye lagophthalmos, thickening of right lateral peroneal and bilateral posterior tibial nerves, sensory impairment, peripheral bilateral facial palsy, and wasting of bilateral distal small muscles of the hands, with normal autonomic function. Nerve Conduction Study revealed multiple demyelinating mononeuropathy of upper and lower extremities. Her serum anti-PGL-1 IgM level was 1721 µ/mL, but after three months of treatment with MDT-PB regimen, it increased to 2815µ/mL. Therefore, the treatment was switched to MDT-MB regimen and 30 mg prednisone. The patient is still undergoing treatment. There has been a slight improvement after treatment with MDT-MB regimen. Nerve biopsy is the gold standard for diagnosis but has its limitations. However, serological test of anti PGL-1 can be a marker and a useful tool as an additional test to confirm the diagnosis, especially for patients with nerve impairments. Difficulties are due to the absence of skin lesions and neuropathy which may be caused by other diseases. Both diagnosis and treatment require multidisciplinary approach. Treatment given is intended to correct nerve damage and prevent further disabilities.

Psoriasis is a chronic inflammatory skin disease known to be highly responsive to phototherapy. Narrow-band UVB (NBUVB) phototherapy has been one of the standard treatments for its moderate to severe form. However, its lack of efficacy in treating stable psoriatic plaques on extremities has lead researchers to find alternative treatments, one of which is pulsed-dye laser (PDL). Laser has been known to be effective in treating vascular lesions; in psoriasis, elongation of rete ridge along with tortuous dermal capillaries are one of the first pathologies identified early in the disease progression. Several in vivo and preliminary studies have found the molecular mechanism of action of laser on abnormal vessel growth. In this article, we report a psoriasis vulgaris case in adult whose lesions responded well to NBUVB phototherapy. The psoriatic plaques on her extremities were stable despite NBUVB therapy and some topical treatments afterwards. With knowledge of emerging role of PDL in inflammatory skin disease such as psoriasis, we conducted a literature search and critically appraised the resulting articles. The systematic review article found evaluates PDL efficacy as a treatment for inflammatory skin diseases, including psoriasis, and was appraised using a worksheet from British Medical Journal Evidence-Based Medicine Toolkit. Its validity, importance, and applicability aspects were evaluated, leading to a conclusion that PDL can be used as an alternative treatment for psoriasis plaques in trunks, extremities, hands, or feet (both stable and unstable), with minimal and transient side effects (hyperpigmentation, hypopigmentation, and blistering).
