Segmentation Problem

Acne vulgaris is one of the most common human pathologies worldwide. Its prevalence causes a high healthcare expenditure. Acne healthcare costs and effects on individuals' quality of life lead to the need of analysing current acne evaluation, treatment and monitoring methods. One of the most common ones is manual lesion counting by a dermatologist. However, this technique has several limitations, such as time spent. That is the reason why the development of new computer-assisted techniques are needed in order to automatically count the acne lesions. Nonetheless, the first step is automatic acne lesion detection on the skin of patients. The aim of this work is to propose a new methodology to solve the acne images segmentation problem, so that the implementation of a system for automatic counting is possible. The results would be a decrease in both time spent and diagnosis errors. With this objective, after doing a systematic review on the state of the art of acne images segmentation methods, fluorescence images of the face of acne patients are obtained. This image modality enhances visualization of the acne lesions. Finally, using the fluorescence images, a segmentation algorithm is implemented in MATLAB.

Background: Acne vulgaris is a very common malady of adolescents. It is common enough to be called as a physiological process but is better regarded as a disease due to its inflammatory component and the disfigurement. Acne vulgaris is a common skin disorder of pilosebaceous unit that primarily affects the face which if not treated leads to pigmentation. Mukhadushika is a Kshudra Roga which mainly involves Kapha and Vatadosa with Raktha. This is a common illness affecting 80 % of adolescents. Lepa is one of the external therapies explained in Ayurvedic classics. Objectives: To evaluate the efficacy of Sidharthakadilepa in the management of mukhadushikaw.s.r. to acne vulgaris. Methods: 30 patients fulfilling the inclusion criteria were selected. They were given Sidharthakadi Lepa for external application over face for one month. Patients were observed for changes on 7th, 14th, 21st and 28th day. The response to therapy was evaluated at the end of 28 days by calculating acne lesion score and the efficacy was determined by the percentage reduction in ALS. Results: The analysis revealed that 40% of patients had complete remission, 30% patients showed marked improvement and 30% showed moderate improvement.

Acne vulgaris is the most common disorder seen in general dermatology practice, accounting for approximately 10% of visits each year. Both sexes and all ethnicities are affected, usually in the late preteenage or early teenage years. Both inflammatory and comedonal lesions of acne vulgaris characteristically involve the face, but truncal involvement is also relatively common. Multiple clinical presentations may be observed, with severity often progressing over time during adolescence. Severe forms of acne vulgaris can be especially disfiguring and debilitating, and are more likely to lead to permanent scarring. Therapeutic options are chosen primarily on the basis of clinical severity, with adjustments in treatment made on the basis of response or disease progression. Rosacea begins in adulthood, usually in the third decade of life or later. The disorder predominantly affects the central face in fair-skinned people, mostly those of northern European ancestry, although individuals of any race may be affected. Rosacea may present as one or more of a variety of clinical phenotypes (subtypes); it is a chronic disorder characterized by periods of exacerbation and remission. Fortunately, rosacea is not associated with scarring, although a subset of patients may develop localized proliferations of sebaceous and fibrous tissue called a phyma. Like acne vulgaris, rosacea may also adversely impact quality of life. Figures in this chapter illustrate acne vulgaris and inflammatory papules. Tables detail laboratory evaluation for women with acne vulgaris and hyperandrogenism, surgical/physical modality options for specific acne lesions and acne scars, major topical therapies for acne vulgaris, and commonly prescribed systemic therapies for acne. This chapter contains 50 references.

Background: Acne vulgaris is a prevalent dermatological disease characterized by skin eruptions, which may decrease the sufferer’s quality of life. Hydrogen purification treatment is a new procedure used in cosmetology to improve the skin parameters of the face. This study examined the effectiveness of hydrogen purification treatment to improve women’s skin conditions with regard to acne vulgaris. Methods: In this study, 30 women participated who suffered from a high level of sebum and acne. The control group was comprised of 30 healthy women with a low level of sebum. The Hellgren–Vincent Scale and Derma Unit SSC 3 device were used to assess acne vulgaris severity and skin properties, respectively. Four hydrogen purification sessions were carried out at 7-day intervals, using the Hebe Hydrogenium+ generating alkaline water. Results: At baseline and 7 and 14 days after finishing the series of treatments, the levels of oiliness, moisture, and skin pH were tested. The main effects of treatment were significant in the following parameters: pH around the bottom lip, moisture between the eyebrows and around the nose, and oily skin in all three face sites. Conclusions: The level of sebum decreased and moisture levels increased during hydrogen purification. Topical hydrogen purification is an effective and safe treatment for acne vulgaris.

BACKGROUND Acne vulgaris is a common disease mostly affecting the adolescents. The lesions can be distributed over the sebaceous rich areas of the body like face, chest, back and upper arm. The commonest location is face. Face is psychologically the most important part of the body. So, the presence of lesions on the face can have significant effects on the quality of life of the patients. The purpose of this study was to assess the effect on the quality of life (QOL) of the patients who have acne vulgaris on their face. Along with that this study was planned to assess as to whether the effect on QOL is related to two demographic factors - age & gender and two clinical factors - duration of disease and grade of acne vulgaris. METHODS 81 patients having acne vulgaris on their face who attended the Dermatology OPD were assessed using the Dermatology Life Quality Index (DLQI) questionnaire. RESULTS Acne vulgaris of the face had significant adverse effect on the QOL of the affected patients. DLQI score was found to be more with increase in age of the patients. There was no significant association between DLQI score & gender. The clinical factors, duration of disease and the grade of acne vulgaris had statistically significant positive correlation with DLQI score. CONCLUSIONS Acne vulgaris had an adverse effect on the QOL of the patients. QOL was more affected with increase in age of the patients. Duration of the lesions and grade of acne vulgaris had a positive correlation with the effect on the QOL of the patients. The lesions can be controlled with treatment. Proper counselling is also very important. KEYWORDS Acne Vulgaris, Quality of Life (QOL), Dermatology Life Quality Index (DLQI)

One third of food produced globally is wasted. Disposal of this waste is costly and is an example of poor resource management in the face of elevated environmental concerns and increasing food demand. Providing this waste as feedstock for black soldier fly (Hermetia illucens) larvae (BSFL) has the potential for bio-conversion and valorisation by production of useful feed materials and fertilisers. We raised BSFL under optimal conditions (28 °C and 70% relative humidity) on seven UK pre-consumer food waste-stream materials: fish trimmings, sugar-beet pulp, bakery waste, fruit and vegetable waste, cheese waste, fish feed waste and brewer’s grains and yeast. The nutritional quality of the resulting BSFL meals and frass fertiliser were then analysed. In all cases, the volume of waste was reduced (37–79%) and meals containing high quality protein and lipid sources (44.1 ± 4.57% and 35.4 ± 4.12%, respectively) and frass with an NPK of 4.9-2.6-1.7 were produced. This shows the potential value of BSFL as a bio-convertor for the effective management of food waste.
