Abstract
Despite the unique physiology and metabolic pathways of microbiomes from cold environments providing key evolutionary insights and promising leads for discovering new bioactive compounds, cultivable bacteria entrapped in perennial ice from caves remained a largely unexplored life system. In this context, we obtained and characterized bacterial strains from 13,000-years old ice core of Scarisoara Ice Cave, providing first isolates from perennial ice accumulated in caves since Late Glacial, and first culture-based evidences of bacterial resistome and antimicrobial compounds production. The 68 bacterial isolates belonged to 4 phyla, 34 genera and 56 species, with 17 strains representing putative new taxa. The Gram-negative cave bacteria (Proteobacteria and Bacteroidetes) were more resistant to the great majority of antibiotic classes than the Gram-positive ones (Actinobacteria, Firmicutes). More than 50% of the strains exhibited high resistance to 17 classes of antibiotics. Some of the isolates inhibited the growth of clinically important Gram-positive and Gram-negative resistant strains and revealed metabolic features with applicative potential. The current report on bacterial strains from millennia-old cave ice revealed promising candidates for studying the evolution of environmental resistome and for obtaining new active biomolecules for fighting the antibiotics crisis, and valuable cold-active biocatalysts.

Abstract
Polycystic ovarian syndrome is an endocrine disorder diagnosed commonly in young women. Various cutaneous manifestations can include acanthosis nigricans, acne, hirsutism, and alopecia. Confluent and reticulated papillomatosis is a rare skin condition that may be associated with polycystic ovarian syndrome. The etiology of confluent and reticulated papillomatosis is not yet well established but multiple theories exist regarding its pathogenesis. We describe a woman with established polycystic ovarian syndrome who presented with confluent and reticulated papillomatosis; her skin condition was successfully treated with azithromycin. The clinical features, differential diagnosis, epidemiology, and proposed etiologies for confluent and reticulated papillomatosis are discussed as well as possible treatment options. Among women with polycystic ovarian syndrome, confluent and reticulated papillomatosis and acanthosis nigricans can occur concurrently. Additionally, it is possible that confluent and reticulated papillomatosis occurs more commonly in this patient population.

Abstract
Confluent and reticulated papillomatosis, also known as Gougerot-Carteaud Syndrome, is a rare chronic disease typically affecting young adults. Of unknown etiology, the condition is characterised by oval grayish-brown or erythematous papules that coalesce to form a reticular pattern, usually on the trunk, especially in the intermammary or interscapular region and on the neck. Diagnosis is primarily clinical, based on the appearance of the lesions, the areas affected, and the response to treatment with minocycline. We report 20 cases of patients with histologically confirmed confluent and reticulated papillomatosis who presented linear pseudo-striae, a little known diagnostic sign.

Abstract
Confluent and reticulated papillomatosis (CRP) of Gougerot and Carteaud was first typified in 1927. With the help of electron microscopy, it has been elucidated that CRP arises due to aberrant keratinization. However, till date, there is no clear consensus on the etiologic trigger for CRP. Prevailing postulates include a bacterial trigger by Dietzia papillomatosis (type strain N 1280(T)), an exaggerated cutaneous response to Malassezia furfur, an endocrine basis stemming from insulin resistance, ultraviolet light-induced epidermal change, amyloid deposition, and a loss-of-function mutation in keratin 16. CRP typically presents as asymptomatic hyperpigmented papules and plaques with peripheral reticulation over the nape, axillae, upper chest, and upper back, occasionally with extension superior to the forehead and inferior to the pubic region. Dermoscopy may be used in the evaluation of CRP, but its diagnosis is made on clinical grounds given its nonspecific histopathological findings. Although successful treatment with topical keratolytics, retinoids, or antifungals has been reported, antibiotics, such as minocycline, at anti-inflammatory doses have emerged as a preferred therapeutic option. In this article, we review the diagnostic considerations in CRP and its therapeutic options.

Abstract
BACKGROUND Terra firma-forme dermatosis was first described in 1987. It is characterized by the appearance in children or adolescents of dirt-like patches despite normal cleansing. The lesions are removed when the skin is rubbed with a 70°C alcohol swab. This largely unknown condition is of uncertain origin but could be due to a keratinisation disorder. PATIENTS AND METHODS Herein we report the case of a 17-year-old male patient who, after seeking the opinions of a number of doctors, consulted in dermatology for multiple pigmented patches on the trunk and limbs that had appeared one year earlier. These lesions had persisted despite appropriate cleansing. He had no history of endocrine disorders and no familial history of pigmentation disorders. A skin biopsy revealed compact orthokeratotic hyperkeratosis resembling a second layer of stratum corneum on top of a normal layer. Very small granules were seen within this layer and PAS staining revealed spores. These skin lesions disappeared when rubbed with an alcohol swab, resulting in a diagnosis of terra firma-forme dermatosis. DISCUSSION Where a diagnosis of terra firma-forme dermatosis is suspected, confirmation is easy to obtain using an alcohol swab. Nevertheless, the disease is not familiar to dermatologists. The most common differential diagnoses are acanthosis nigricans, reticulate and confluent papillomatosis, and Dowling-Degos disease. Their histopathological appearances are very different and skin biopsy can be useful for diagnosis. These entities belong to a group of disorders involving abnormal keratinisation and pigmentation. Anatomoclinical correlation is essential for optimal management. The appearance of the stratum corneum may play an important role in the diagnosis of terra firma-forme dermatosis.

Abstract
BACKGROUND Confluent and reticulated papillomatosis (CRP) is an uncommon dermatosis with a reticular pattern. As differentiation between CRP and benign acanthosis nigricans (AN) can be challenging because of their similar clinicopathological features, we aimed to distinguish the two diseases. METHODS We retrospectively reviewed the clinical characteristics of 60 CRP and 30 AN patients. Histological examinations were conducted on 33 CRP and 30 AN lesions. RESULTS While CRP was concentrated on the trunk, AN mostly appeared in the axilla. In the AN group, the number of obese patients was higher, and acanthosis and papillomatosis were more evident. In both group, increases in Ki-67 and keratin 16 expression were similar. Bacterial infection was detected at a higher rate in CRP lesions than in AN lesions.AN lesions had greater pigmentation because of a high number of melanocytes than CRP lesions. CONCLUSIONS The location of skin lesions and body mass index are the main clinical factors that enable differentiation between CRP and AN. The epidermal histological changes in CRP are milder than those in AN. AN lesions also showed a greater degree of pigmentation and melanocytic proliferation.

Abstract
BACKGROUND Confluent and reticulate papillomatosis of Gougerot and Carteaud (CRP) is a rare dermatological condition, which has not been reported widely in Asian populations. AIM To characterize the clinicopathological and diagnostic features of CRP in a South-East Asian population. METHODS The medical records of 29 patients accorded the diagnosis of CRP at the National Skin Centre, Singapore, from 1990 to 2011, were analyzed. RESULTS The male to female ratio was 2.6:1. Eight patients were Indians. The mean age at the onset of skin eruptions was 29.1 years (range 16-55 years), while the mean duration was 19.9 months (range 0.5-120 months). CRP itself was the most common preliminary diagnosis. Fungal smears were negative in all 22 instances. All 29 patients had received a trial of antifungal therapy before being seen at our center. Antifungal therapy was repeated in three subjects, and the response was uniformly poor. Conversely, the treatment response with tetracyclines was excellent, yielding more than a 50% response in all 14 patients. Four patients suffered recurrence of CRP. According to the diagnostic criteria set forth by Davis et al., 25/29 patients (86.2%) and 19/29 patients (65.6%) fulfilled at least three and four criteria, respectively. CONCLUSION A predilection for male gender and Indian ethnicity were noted in our study. The diagnosis of CRP was often made clinically, and investigations were mainly ancillary. The treatment response was poor with antifungal agents but excellent with tetracyclines. The diagnostic criteria proposed by Davis et al. were found to be useful in our cohort of patients.

Abstract
The majority of nonbacterial dermatological conditions treated with antibiotics benefit from the anti-inflammatory properties of these medications, usually dapsone or tetracycline. Many other antimicrobials are used to treat noninfectious conditions. The following chapter is an overview of select noninfectious dermatological conditions for which antibiotics are used, with a focus on the most common antibiotics used for their nonantimicrobial properties.

Abstract
The genus Dietzia has only been established fairly recently. The Gram morphology and colony appearance of the species of this genus is remarkably similar to Rhodococcus equi. In the absence of simple, accurate methods for their identification, Dietzia spp. might have been misidentified as a Rhodococcus spp. and/or considered to be contaminants only. This MiniReview is designed to summarize current evidence on the clinical significance of Dietzia species, to consider their potential role as human pathogens, and to outline approaches that can be used to accurately classify and identify members of the genus, with the overall aim of alerting the medical microbiological community to a little known genus that contains clinically significant organisms.

Abstract
A bacterial strain, named P4, isolated previously from microcosms containing oil-contaminated soil collected from an environmentally protected area of a tropical Atlantic forest (Biological Reserve of Poço das Antas) located in Brazil was identified as Dietzia cinnamea by morphological, biochemical and genotypic tests. Arabian Light and Marlin oils were both degraded when strain P4 was tested for oil degradation ability in microplates. Total Petroleum Hydrocarbons (TPH) analysis, determined by gas chromatography, showed that strain P4 degraded a wide range of n-alkanes, and also pristane and phytane. Furthermore, this strain was also able to grow in mineral liquid media amended with carbazole, quinoline, naphthalene, toluene, gasoline and diesel as the sole carbon sources. The species D. cinnamea has been previously described with only one representative strain isolated from a perianal swab of a patient with a bone marrow transplant. With the results presented here this species is implicated not only as a human pathogen but also as a potential strain for further studies concerning its role for bioremediation of oil contaminated soil.

Abstract
Confluent and reticulated papillomatosis is a rare dermatosis of unknown etiology mostly affecting young males and females most common in adolescence. The eruption consists of confluent, flat, brown papules forming a pigmented reticulated pattern. It occurs primarily in the intermammary and epigastric regions but may spread to the axillae. A 27-year-old patient with typical clinical and histologic features of confluent and reticulated papillomatosis responded well to oral minocycline.

Abstract
Confluent and reticulated papillomatosis (CARP) was first described >60 years ago. It is distinct from acanthosis nigricans. This article presents the results of a review of the literature in MEDLINE through May 2006 using the terms 'confluent and reticulated papillomatosis', 'reticulated and confluent papillomatosis of Gougerot and Carteaud', and 'reticulated papillomatosis'. A recent report has linked the presence of Dietzia spp. (family: Dietziaceae; suborder: Corynebacterineae; order: Actinomycetales) in the skin to CARP. CARP has also been linked to defects in keratinization. Other possible causes of CARP that have been suggested but seem less likely include endocrine abnormalities, Pityrosporum, a reaction to UV light, and a variation of cutaneous amyloidosis. CARP has been reported worldwide and occurs in both sexes, all age groups, and all races. The disorder can initially manifest as hyperkeratotic or verrucous papules that coalesce to form a reticular pattern peripherally and confluent plaques centrally. Although a variety of treatments for CARP exist, oral minocycline 50-100mg twice daily has been the preferred treatment. However, recent reports of the effectiveness of azithromycin 250-500mg three times weekly may make azithromycin the preferred treatment for CARP, since it has a more benign adverse effect profile than minocycline. Other effective antibacterial treatments include fusidic acid 1000mg daily, clarithromycin 500mg daily, erythromycin 1000mg daily, tetracycline 500mg twice daily, and cefdinir 300mg twice daily. If a recent finding that CARP is caused by a bacterial microorganism is replicated, treatment should likely be determined by bacterial sensitivities, antibacterial adverse effect profiles, and cost considerations. Other oral treatments of CARP that are effective but currently disfavored because of the effectiveness of minocycline include isotretinoin, acitretin, and etretinate. There have been mixed reports regarding the effectiveness of topical treatments, which include selenium sulfide, ketoconazole cream, tretinoin, tazarotene, tacalcitol, and calcipotriene (calcipotriol).
