Background: VO2 Max (maximal oxygen uptake) is a capability of oxygen with maximal capacity that used to the body to perform maximal exercise. The factor that most influence of VO2 Max is a physical activity. Cardiorespiratory endurance can be enhanced objectively by doing exercises or sports regularly, structurally, and continuously performed. Pedicab driver does his job by pedaling a pedicab every day, whereas the taxi driver does his job by driving a taxi every day. The aims of this study are to determine the differences of VO2 Max scores between pedicab drivers and taxi drivers in Surakarta. Methods: This study was an observational analytic with cross-sectional approach. The selection of the samples from the population has been conducted with purposive sampling. This study was conducted in the base of Kosti Solo in Mojosongo and in Surakarta. Two groups of samples, 30 taxi drivers and 30 pedicab drivers with the inclusion criteria (man, age 40 - 50 years; BMI ranged from 18.5 kg/m2 â 25.0 kg/m2; diastolic blood pressure < 100 mmHg; willing to be responders and filling and approved informed-consent; pursue work at least 5 years) conducted a study using Multistage Fitness Test (MFT), which the test is to run back and forth 20 yards. This value can be converted into the equivalent VO2 Max score using prediction table of the VO2 Max. The data were analyzed using non paired t-test (Î± = 0.05). Results: The results showed the mean scores predicted of the VO2 Max in pedicab driver was 25.79, while the taxi driver was 20.87. The data were analyzed by using non paired t-test that showed significantly differences between the two study groups, p = 0.000 (p < 0.05). Conclusion: There are significant differences of VO2 Max between the pedicab drivers and taxi drivers in Surakarta. Keywords: VO2 Max, pedicab drivers, taxi drivers, cardiorespiratory endurance, MFTÂ

Background : Brewed green tea contains antifungal substance such as polyphenol which is considered can inhibit fungal growth. The aim of this research is to determine antifungal effect of brewed green tea (Camellia sinensis L.) against Candida albicans growth In Vitro. Methods : The research was performed as experimental laboratory. The subject of this research were clinical sample of Candida albicans and taken randomly. This research used 7 treatment groups, they were sterilized aquadest as negative control, brewed green tea with concentration of 60%, 70%, 80%, 90% and 100%, also fluconazole 25 g as positive control. This research was repeated four times. The plate was incubated at the temperature of 37C for 48 hours then inhibition diameter zone formed was measured. The data was analyzed by Linier Regression test then continued by Correlation test on IBM Statistics for Windows version 20. Results : The diameter of inhibition zone increased along with increasing concentrations, because higher concentration of brewed green tea contained more substances, and the diameter of concentration of 100% group is almost the same with diameter of positive control group. The results of statistical analysis using Linier Regression test showed that there are significant differences on seven of treatment groups (p < 0,05) and the Correlation test showed that there are close relation between concentration of brewed green tea and the diameter of inhibition zone. Conclusion : Brewed green tea (Camellia sinensis L.) has antifungal effect against Candida albicans growth In Vitro. Start from concentration of 60% up to 100%, there were antifungal effect, and the antifungal effect of concentration of 100% is close to fluconazole 25 g/ml.

Background: Keloid is a growth of fibrous tissue in the wound tissue of susceptible individuals. This tissue extends beyond the boundaries of the previous wound. The site of keloids commonly appears on a high-tension area, such as the chest, shoulders, and neck. Histopathologically keloids show thickened the epidermis and the vascularization and infiltration of inflammatory cells in the dermis. Purpose: This study aims to determine the relationship between the site of keloids and the histopathological appearance of keloids. Methods: An analytical observational study was conducted on keloid patients visiting the Dermatovenereology outpatient clinic of Dr.Moewardi Hospital. The sample collection used consecutive sampling techniques Result: The majority of keloid patients are >30 years old (46.4%). Most patients with keloids were female (53.6%). Keloids were mostly found on the chest (25.0%). Tounge-like appearance of the epidermis at the edges of the lesions was mostly on the shoulders and chest (33.3% each, p=0.048); flattened appearance was found on the middle epidermis of the lesions, which were mostly on the ears, shoulders, and upper extremities (22.7% each, p=0.011). Increased vascularity was found in the dermis at the edges of the lesions, especially in the ear and chest areas (31.3% each, p=0.046). Moderate-severe inflammatory infiltrates in the dermis at the edges of the lesions were commonly found on the chest (p=0.04). Conclusion: There is a significant relationship between the site of the lesion and the histopathological appearance of the keloid in epidermal as well as dermal layers.

Background: Eosinophilic pustular folliculitis (EPF), or Ofuji disease, is a rare non-infectious inflammatory dermatosis typically affecting middle-aged adults. Its clinical resemblance to infectious exanthems often leads to significant diagnostic delays, particularly in atypical age groups. Case presentation: A 15-year-old male presented with a one-month history of progressive erythematous papules, pustules, and crusted erosions distributed across the face, trunk, and extremities. The patient was initially misdiagnosed with varicella and treated with acyclovir without clinical response. Physical examination and Gram staining ruled out primary bacterial infections. Laboratory investigations revealed significant peripheral eosinophilia (12.3%). A 5-mm punch biopsy confirmed the diagnosis, showing dense eosinophilic and neutrophilic infiltration of the hair follicles and peri-adnexal structures. Management with systemic and topical corticosteroids led to rapid resolution of lesions and normalization of eosinophil levels. Conclusion: This case underscores the necessity of considering EPF in the differential diagnosis of persistent papulopustular eruptions in adolescents. Early histopathological intervention is critical to prevent unnecessary antimicrobial therapy and ensure targeted anti-inflammatory treatment.
