RESUMO
BACKGROUND: Anastomotic leakage (AL) represents a severe complication after rectal surgery, leading to significant morbidity, mortality, and increased healthcare costs. Despite improvements in surgical methods and perioperative care, the challenge of AL persists. OBJECTIVES: Explore the impact of body mass index (BMI) on the risk of AL following curative treatment for rectal cancer, providing insight into its predictive value. DESIGN: Retrospective review. SETTINGS: Data were collected from a single tertiary center, emphasizing the specialized postoperative outcomes in a high-care setting. PATIENTS AND METHODS: The study population was comprised patients who underwent sphincter-saving surgery combined with neoadjuvant chemoradiation for rectal cancer from 2001 to 2011. Patients with anastomotic stenosis were excluded. MAIN OUTCOME MEASURES: The primary outcome investigated was the occurrence of AL post-surgery. Secondary outcomes included the assessment of local cancer recurrence rates within the AL group. SAMPLE SIZE: 224; 13 excluded. RESULTS: Of 237 patients who underwent surgery, 13 with anastomotic stenosis were excluded from this study. Of the remaining 224, 15 individuals (6.3%) developed AL. A potential association between higher BMI and increased AL risk was identified. Additionally, the study noted a higher incidence of local rectal cancer recurrence in the group that developed leakage. CONCLUSION: The findings suggest BMI as a significant predictive factor for AL after curative rectal cancer treatment. This emphasizes the need for heightened awareness and possible preoperative counseling for obese patients regarding their increased risk of postoperative leakage. LIMITATIONS: The study was retrospective with all the inherit biases of such studies. The sample size was small and this may have introduced a type 2 statistical error.

Encryption is a fundamental security measure to safeguard data during transmission to ensure confidentiality while at the same time posing a great challenge for traditional packet and traffic inspection. In response to the proliferation of diverse network traffic patterns from Internet-of-Things devices, websites, and mobile applications, understanding and classifying encrypted traffic are crucial for network administrators, cybersecurity professionals, and policy enforcement entities. This paper presents a comprehensive survey of recent advancements in machine-learning-driven encrypted traffic analysis and classification. The primary goals of our survey are two-fold: First, we present the overall procedure and provide a detailed explanation of utilizing machine learning in analyzing and classifying encrypted network traffic. Second, we review state-of-the-art techniques and methodologies in traffic analysis. Our aim is to provide insights into current practices and future directions in encrypted traffic analysis and classification, especially machine-learning-based analysis.
RESUMO
INTRODUCTION: Pharmaceutical regulation on a global scale is a complex process, with regulatory bodies overseeing various aspects, including licensing, registration, manufacturing, marketing, and labeling. Among these, the USFDA plays a crucial role in upholding public health. The pharmaceutical industry contributes significantly to well-being by developing and distributing therapeutic agents. The journey of evaluating new pharmaceuticals involves meticulous examination through several phases, from safety and efficacy assessments to toxicity evaluation. Drug approval involves submitting New Drug Applications (NDAs) to regulatory agencies like the USFDA and EMA. However, disparities in durations contribute to the phenomenon known as "drug lag." This lag refers to delays in a pharmaceutical product's availability in one market compared to another. Addressing this issue is crucial, given its impact on patient access to treatments. METHOD: This study aims to analyze the extent of drug lag, focusing on newly approved oncology targeted therapies in Saudi Arabia, the United States, and the European Union. Data for cancer treatments authorized by the USFDA, EMA, and SFDA from January 1, 1997, to December 31, 2022, were collected from regulatory agency websites. The data sources included authorization letters, prescription information, and evaluation documents. We conducted a comparative assessment of drug lag for approved oncology targeted therapies between Saudi Arabia, the US, and the EU. RESULT: Our analysis identified 135 newly approved oncology-targeted drugs within the specified timeframe. Of these, 71 received approval in all three regions, while disparities were evident in others. The USFDA consistently had the highest number of approved drugs, with 98.5% of drugs initially approved there. In contrast, Saudi Arabia had the lowest number of approved drugs and a significantly longer median drug lag, indicating substantial delays in drug availability. CONCLUSION: This study highlights the significance of mitigating drug lag to enhance global healthcare outcomes and patient access to innovative therapies. Further research and collaborative efforts are essential to bridging these disparities and promoting equitable healthcare worldwide.

OBJECTIVE: "Metabolic syndrome" (MetS) is a set of abnormalities that may be risk factors for cardiovascular disease (CVD) and diabetes. The current study sought to (1) determine MetS prevalence and (2) examine Adiponectin and ANGPTL8 levels in connection to MetS components and CVDs and diabetes risk in females with MetS. METHODS: A total of 350, 20-35-year-old Saudi females were studied. Waist circumference (WC), body mass index (BMI), glucose, HbA1c, insulin, lipid profiles, and blood pressure (BP) were examined for MetS. ANGPTL8 and Adiponectin were also measured. RESULTS: The patients were classified into two groups, namely MetS and non-MetS, according to the criteria established by the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). We examined biomarker and anthropometric results between these groups. One hundred forty-four of 350 female participants (41.2%) had MetS, with a mean age of 30.5 years. Fasting blood glucose (FBG), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), ANGPTL8, adiponectin, and insulin resistance (IR) were statistically significant differences observed between the two groups. BP, BMI, WC, and Atherogenic Index of Plasma (AIP) all changed significantly (P ≤0.05). Correlation studies linked MetS components to higher ANGPTL-8 and reduced adiponectin. The levels of ANGPTL8 were shown to be influenced by the increase in FBG, TG, BP, IR, and AIP (P < 0.05). Factors such as FBG, BMI, WC, and IR have been found to have an inverse relationship with adiponectin levels. CONCLUSION: 41.2% out of 350 Saudi females at Taibah University in the Madinah region had MetS, medium CVD risk, and slightly elevated BMI, TG, WC, and BP. To lower their risk of CVD and diabetes later in life, overweight young women should be evaluated for MetS. FBG and TG were substantially associated with ANGPTL8 while reducing adiponectin was associated with elevated TG and BP. Our findings may lead to ANGPTL8 and adiponectin's possible predictive function for CVD in early MetS in females.
RESUMO
The prevalence of venous thromboembolism is high in patients with COVID-19, despite prophylactic anticoagulation. The evidence that supports the preferred thromboprophylaxis regimen in non-critically ill patients with mild to moderate COVID-19 is still limited. Therefore, this systematic review and meta-analysis aimed to compare the clinical outcomes of hospitalized patients with mild to moderate COVID-19 who received standard thromboprophylaxis anticoagulation with intermediate to high prophylaxis regimens. We systematically searched MEDLINE and Embase databases for published studies until August 17th, 2022. We included studies on patients with mild to moderate COVID-19 who received thromboprophylaxis during their hospital stay. Patients who received standard prophylaxis dose "control group" were compared to patients who received intermediate to high prophylaxis "intervention group". Random effect models were used when pooling crude numbers and adjusted effect estimates of study outcomes. A comprehensive analysis was conducted, encompassing seven studies involving a total of 1931 patients. The risk of all-cause thrombosis was not statistically different between the two groups (risk ratio [RR] 1.48, 95% confidence interval [CI] [0.11, 20.21]). The risk of minor bleeding was reported to be lower in patients who received intermediate to high prophylaxis (RR 0.64, 95% CI 0.21, 1.97), while had a higher risk of major bleeding compared with the standard prophylaxis (RR 1.40, 95% CI 0.43, 4.61); however, did not reach the statistical significance. The overall risk for all hospital mortality favored the utilization of intermediate to high doses over the standard thromboprophylaxis dosing (RR 0.47, 95%CI 0.29, 0.75). In medically ill patients with COVID-19, there is no difference between standard and intermediate to high prophylaxis dosing regarding thrombosis and bleeding. However, it appears that intermediate to high prophylaxis regimens are linked to additional survival benefits.

Compassion fatigue (CF) poses significant challenges to healthcare workers' (HCWs) well-being. This study aimed to estimate the prevalence of CF and identify its predictive factors among HCWs in all regions of Saudi Arabia (SA). As such, all HCWs from different disciplines in different centers were allowed to participate, resulting in 678 participants. The study tool, distributed between October 2022 and January 2023, consisted of a questionnaire created by the authors based on the Professional Quality of Life Scale (ProQOL). The ProQOL measures the positive (compassion satisfaction [CS]) and negative (CF) effects of helping those who have suffered, noting that burnout (BO) and secondary traumatic stress (STS) are the two subscales that constitute CF. Our findings revealed that 63.9% of HCWs experienced average STS, while 57.2% reported average BO levels. HCWs in the southern and northern regions exhibited higher STS (p-value = 0.003 and 0.010, respectively). Physicians displayed higher BO levels (p-value = 0.024). Higher levels of CS were found among older HCWs (p-value = 0.001) and lower levels among those with more years of experience (p-value = 0.004). Support at work and job, life, and financial income satisfaction were significantly and positively correlated with CS and negatively correlated with BO and STS. These findings highlight the need for tailored awareness campaigns targeting HCWs, particularly physicians, to promote well-being, enhance coping skills, and foster problem-solving techniques. Keywords: burnout; compassion fatigue; compassion satisfaction; healthcare workers; professional quality of life; Saudi Arabia; secondary traumatic stress; medical trainees' well-being.
RESUMO
Exopolysaccharide-producing cyanobacterial strains in biological soil crusts are described, in addition to their chemical properties and antioxidant and flocculation activities. The EPSs from Pudukkottai blackish biological soil crusts (PBBSCs) showed significant amounts of total soluble proteins (0.1687 mg/mL) and carbohydrates (0.8056 mg/mL) compared with the Ariyalur blackish biological soil crusts (ABBSCs). LC-MS analysis of the cyanobacterial polysaccharides revealed the presence of natural sugars such as ribose and glucose/mannose, and uronic acids. The FTIR spectrum showed specific peak for OH and -NH stretching, C-H stretching, and carboxylic acids as the dominant groups in EPS. The in vitro DPPH assay of EPSs from PBBSCs showed 74.3% scavenging activity. Furthermore, the reducing power was determined to be 0.59 ata 500 mg/mL concentration, respectively. The extracted EPSs from the biological soil crust flocculated Kaolin clay suspension maximum at 500 mg/mL. Consequently, the cyanobacterial strain and exopolysaccharide characterization from the sacred forest's biological soil crust were analyzed for their bioactive potential, bio-crust diversity, and distribution.
RESUMO
OBJECTIVES: Self-harm rates and clinical presentations differ by ethnicity. South Asian women are at risk of self-harm. Previous research suggested investigating individuals' experiences with self-harm with qualitative studies in developing self-harm prevention strategies. This research aims to explore self-harm experiences among South Asians in the United Kingdom. DESIGN: Qualitative study. METHODS: Participants were recruited via third-sector organizations and online platforms. Semi-structured interviews were conducted with 11 South Asian individuals with a history of self-harm living in the United Kingdom. The data were analysed based on a reflective thematic analysis approach. RESULTS: Results revealed four main themes: (1) reasons for self-harm; (2) recovery journey; (3) culture and mental health; and (4) the transition to suicidal thoughts and behaviours. Reasons for self-harm included negative life circumstances, social life difficulties, challenges faced during COVID-19 and mental health problems. Participants described their recovery journey by acknowledging the role of professional help, self-care, psychoeducation and personal growth, improving social relationships, and faith and spirituality. Cultural factors included generational differences and stigma. Culturally adapted psychological interventions were perceived as promising. The reported transition from self-harm to suicidal behaviours was linked to experiencing major stressful life events and the use of severe methods of self-harm. CONCLUSIONS: The findings suggest that socio-cultural factors impact mental health and recovery processes among South Asians. Mental health services should consider improving culturally sensitive clinical practices in responding to self-harm among South Asian communities.

This study examined the ability of the green microalgae Chlorella vulgaris to remove arsenic from aqueous solutions. A series of studies was conducted to determine the optimal conditions for biological arsenic elimination, including biomass amount, incubation time, initial arsenic level, and pH values. At 76 min, pH 6, 50 mgL-1 metal concentration, and 1 gL-1 bio-adsorbent dosage, the maximum removal of arsenic from an aqueous solution was 93%. The uptake of As (III) ions by C. vulgaris reached an equilibrium at 76 min of bio-adsorption. The maximum adsorptive rate of arsenic (III) by C. vulgaris was 55 mg/gm. The Langmuir, Freundlich, and Dubinin-Radushkevich equations were used to fit the experimental data. The best theoretical isotherm of Langmuir, Freundlich, or/and Dubinin-Radushkevich for arsenic bio-adsorption by Chlorella vulgaris was determined. To choose the best theoretical isotherm, the coefficient of correlation was used. The data on absorption appeared to be linearly consistent with the Langmuir (qmax = 45 mgg-1; R2 = 0.9894), Freundlich (kf = 1.44; R2 = 0.7227), and Dubinin-Radushkevich (qD-R = 8.7 mg/g; R2 = 0.951) isotherms. The Langmuir and Dubinin-Radushkevich isotherms were both good two-parameter isotherms. In general, Langmuir was demonstrated to be the most accurate model for As (III) bio-adsorption on the bio-adsorbent. Maximum bio-adsorption values and a good correlation coefficient were observed for the first-order kinetic model, indicating that it was the best fitting model and significant in describing the arsenic (III) adsorption process. SEM micrographs of treated and untreated algal cells revealed that ions adsorbed on the algal cell's surface. A Fourier-transform infrared spectrophotometer (FTIR) was used to analyze the functional groups in algal cells, such as the carboxyl group, hydroxyl, amines, and amides, which aided in the bio-adsorption process. Thus, C. vulgaris has great potential and can be found in eco-friendly biomaterials capable of adsorbing arsenic contaminants from water sources.
RESUMO
BACKGROUND: Fasting during the holy month of Ramadan is a religious ritual practiced by the majority of Muslims around the globe. This daytime fasting is short-term or intermittent fasting, which may be associated with valuable health benefits, particularly in cancer patients. METHODS: A prospective cohort study of pre- and post-fasting evaluation of 37 colorectal cancer (CRC) patients was conducted at King Abdulaziz Medical City (KAMC) and King Abdullah Specialized Children's Hospital (KASCH)-oncology outpatient clinics. The study aimed to assess the impact of fasting during the holy month of Ramadan on the tolerability of chemotherapy side effects and to assess changes in the levels of carcinoembryonic antigen (CEA) and lactate dehydrogenase (LDH) tumor biomarkers, which are primarily associated with certain types of carcinomas, including CRC. RESULTS: A total of 33 patients (89.2%) had fasted at least part of the month of Ramadan. Twenty-seven patients (73%) reported "Serenity" after fasting during Ramadan with improved tolerability of chemotherapy side effects. However, the results did not reveal any significant difference in the measured laboratory variables between pre-fasting values and by the end of the 30 days of Ramadan. Although statistically insignificant, the levels of CEA and LDH were reduced in 46.9% and 55.6% of patients, respectively. The mean level of CEA in the fasting group was substantially reduced by more than 40%, attributed to the highly significant decline of CEA levels in three patients (p=0.0283). Moreover, there were no significant differences between pre- and post-fasting blood creatinine levels or estimated glomerular filtration rates, ruling out any possible adverse effects of fasting on renal function. CONCLUSION: The current study confirms the safety and tolerability of intermittent fasting in CRC patients actively receiving chemotherapy, which is consistent with several reports. Nonetheless, the results did not reveal a significant decrease in CEA and LDH tumor biomarkers.
RESUMO
OBJECTIVE: The aim of this study was to translate and validate the chronic pain score (CP score) in a cohort of colon cancer patients. Chronic pain following colon cancer surgery is still poorly understood, in particular the lack of a validated tool for measuring chronic pain is a major issue as such an instrument is critical for evaluating the incidence and risk factors. The CP score was created using data from Danish rectal cancer patients. METHODS: Danish colorectal cancer survivors diagnosed between 2001 and 2014 completed the CP score and two quality of life (QoL) measures. Clinical data were obtained from a national database. Convergent validity was investigated by testing the association of the CP score with a single ad hoc QoL item and the EORTC QLQ-C30, and discriminative validity was tested as the score's ability to differentiate between gender and age groups. Sensitivity and specificity were evaluated by determining the ability of the score to identify patients with a major impact of pain on QoL. RESULTS: Responses from 7127 colon cancer were included. Convergent validity was confirmed, as the score was associated with both QoL measures (p < 0.001). Moreover, the score could differentiate between males/females and older/younger patients (p < 0.001, respectively), reflecting high discriminative validity. Finally, the score was able to identify patients with a major impact on QoL, with a sensitivity of 87% and specificity of 82%. CONCLUSION: The CP score is a valid tool for measuring chronic pain after colon cancer surgery and should be used to homogenize outcomes in future studies.

Sacrococcygeal pilonidal sinus disease (SPND) is an acquired chronic disease with no precise etiopathogenesis. The morbidity associated with the disease necessitates the implementation of new techniques, such as sinus laser therapy (SiLaT), to improve disease management. However, surgical techniques as of now are preferred as the mainstay mode of treatment. A retrospective study was conducted to evaluate and report the healing outcome of the application of SiLaT on patients with SPND at a tertiary center. All patients who underwent SiLaT for primary or recurrent pilonidal sinus from February 2012 to December 2019 were included in the study and followed up for at least six months. Forty-one participants (37 males (90.2%) and four females (9.8%)) were included. Of the participants, 58.5% presented with chief complaints of painful swelling with mucopurulent discharge. Most of the participants were students (43.9%). SiLaT was the primary intervention for 82.9% of the participants. The mean duration of hospital stays, resumption of regular activity, and complete wound healing by secondary intention were 30±21.5 hours, 18.4±14.3 days, and 6.5±6.6 weeks, respectively. Around 95.1% of wounds healed without complications. The overall recurrence rate was 24.4%, while the recurrence rate with SiLaT being the primary intervention was 11.8%. Only three (7.32%) patients experienced wound infections as postoperative complications. The visual analog scale (VAS) score decreased postoperatively in the first and second weeks to 3.9±3.2 and 1.9±1.9, respectively, and 78.1% of the total patients showed satisfaction post-surgical interventions. The current study showed that the SiLaT technique is a feasible technology with promising results to evolve. Further studies are encouraged.
RESUMO
Background: A good understanding of the possible risk factors for coronavirus disease 19 (COVID-19) severity could help clinicians in identifying patients who need prioritized treatment to prevent disease progression and adverse outcome. In the present study, we aimed to correlate clinical and laboratory characteristics of hospitalized COVID-19 patients to disease outcome in Saudi Arabia. Materials and Methods: The present study included 199 COVID-19 patients admitted to King Fahd Specialist Hospital, Buraydah, Qassim, Saudi Arabia, from April to December 2020. Patients were followed-up until discharge either for recovery or death. Demographic data, clinical data and laboratory results were retrieved from electronic patient records. Results: Critical COVID-19 cases showed higher mean of age and higher prevalence of co-morbid conditions. Fifty-five patients died during the observation period. Risk factors for in hospital death for COVID 19 patients were leukocytosis (OR 1.89, 95% CI 1.008-3.548, p = 0.081), lymphocytopenia (OR 2.152, 95% CI 1.079-4.295, p = 0.020), neutrophilia (OR 1.839, 95% CI 0.951-3.55, p = 0.047), thrombocytopenia (OR 2.152, 95% CI 0.852-5.430, p = 0.085), liver injury (OR 2.689, 95% CI 1.373-4.944, p = 0.003), acute kidney injury (OR 1.248, 95% CI 0.631-2.467 p = 0.319), pancreatic injury (OR 1.973, 95% CI 0.939-4.144, p = 0.056) and high D dimer (OR 2.635, 95% CI 0.747-9.287, p = 0.091). Conclusion: Clinical and laboratory data of COVID-19 patients may help understanding the pathogenesis of the disease and subsequently improve of the outcome of patients by determination of the associated risk factors and recognition of high risk group who are more liable for complications and in hospital death. The present study put an eye on some parameters (laboratory and clinical) that should be alarming signs that the patient is at high risk bad prognosis.
RESUMO
BACKGROUND: The term "telemedicine" refers to the use of communication technology to deliver health care remotely. The COVID-19 pandemic had substantial impacts on health care delivery from 2020 onward, and it was necessary to adapt high-quality care in a manner that limited the potential for viral exposure of both patients and health care workers. Physicians employed video, phone, and electronic written (e-consultation) visits, all of which provided quality of care comparable to that of face-to-face visits while reducing barriers of adopting telemedicine. OBJECTIVE: This study sought to assess physicians' perspectives and attitudes regarding the use of telemedicine in Riyadh hospitals during the COVID-19 pandemic. The main objects of assessment were as follows: (1) physicians' experience using telemedicine, (2) physicians' willingness to use telemedicine in the future, (3) physicians' perceptions of patient experiences, and (4) the influence of telemedicine on burnout. METHODS: This study employed SurveyMonkey to develop and distribute an anonymous 28-question cross-sectional survey among physicians across all specialty disciplines in Riyadh hospitals. A chi-square test was used to determine the level of association between variables, with significance set to P<.05. RESULTS: The survey was distributed among 500 physicians who experienced telemedicine between October 2021 and December 2021. A total of 362 doctors were included, of whom 28.7% (n=104) were consultants, 30.4% (n=110) were specialists, and 40.9% (n=148) were residents. Male doctors formed the majority 56.1% (n=203), and female doctors accounted for 43.9% (n=159). Overall, 34% (n=228) agreed or somewhat agreed that the "quality of care during telemedicine is comparable with that of face-to-face visits." Approximately 70% (n=254) believed that telemedicine consultation is cost-effective. Regarding burnout, 4.1% (n=15), 7.5% (n=27), and 27.3% (n=99) of the doctors reported feeling burnout every day, a few times a week, and a few times per month, respectively. CONCLUSIONS: The physicians had generally favorable attitudes toward telemedicine, believing that its quality of health care delivery is comparable to that of in-person care. However, further research is necessary to determine how physicians' attitudes toward telemedicine have changed since the pandemic and how this virtual technology can be used to improve physicians' professional and personal well-being.
RESUMO
This study is intended to evaluate the cytotoxicity of native and dual-modified black rice flour against the colon cancer cell line (HCT116) and mouse embryo cell line (3T3-L1) by using the MTT assay. The modification techniques applied to prepare rice flour samples were enzymatic modification and heat moisture treatment. In this study, the IC50 of native black rice flour and modified black rice flour was 255.78 µg/mL and 340.85 µg/mL, respectively. The result confirms that the native black rice flour has significant cytotoxic and anticancer potential against human colon cancer cells. In addition, the IC50 of native black rice flour and modified black rice flour on the 3T3-L1 cell line was found to be 345.96 µg/mL and 1106.94 µg/mL, respectively. The results showed that the native black rice flour had weak cytotoxicity, and modified black rice flour was nontoxic in both the cell lines. The active component of phytochemicals present in black rice flour has a potential role in preventing colon cancer.
RESUMO
BACKGROUND: Pelvic Floor Dysfunction (PFD) is a global health problem affecting millions of women worldwide and comprises a broad range of clinical dysfunctions such as urinary incontinence (UI), fecal incontinence (FI), pelvic organ prolapse (POP) vaginal laxity (VL), vaginal wind (VW), and overactive bladder (OAB). This study aims to estimate the prevalence of PFD among Saudi women attending primary health care centers (PHCCs) across 13 regions of Saudi Arabia and their characteristics along with associated factors. METHODS: A cross-sectional study was conducted on 2,289 non-pregnant women. The probability population proportional sampling technique was employed followed by a convenient sampling technique to recruit eligible women. Types of PFD were assessed using a self-administered electronic questionnaire. Pelvic Floor Distress Index (PFDI-20) was used to assess the primary study outcomes (FI, VL, POP, VW, and OAB). A multivariate logistic regression model was used to identify independent associated factors for PFD. RESULTS: The findings showed that 830 women (36.3%) had any type of UI. Stress UI affected726 (31.7%) women, whilst 525 women (22.9%) had urge UI. VL occurred in 505 women (22.1%), whilst POP occurred in 536 women (23.4%). VW occurred in 733 participants and (32%) 1238 women (54.1%) had OAB. The multivariate analysis suggested that region, location, parity, and assisted birth were significantly associated with UI, VL, FI and PFD (P < 0.001). CONCLUSION: PFD is a common condition among Saudi women. UI, VL, VW, OAB, POP and FI increased consistently among urban women with increased age, greater parity, assisted birth, and post-menopausal status.

BACKGROUND Endometriosis, a common condition among women of reproductive age and infertile women, occurs when the endometrium extends outside the uterus. When this endometrial tissue grows and sheds, symptoms will develop. The presentation varies depending on the site involved; however, cyclical pain is among its most common symptoms, along with bleeding and cramping. It is frequently observed in the ovaries and fallopian tubes; in contrast, the anal canal is rarely involved. Here, we report a very unusual presentation of the disease. CASE REPORT A 33-year-old woman with a history of episiotomy presented to the Emergency Department reporting perianal swelling in the previous year. The swelling was associated with intermittent pain and difficulty passing stool. She reported no fever. On examination, there was a 3×4 cm palpable tender perianal mass extending to the anal sphincter at the 11 o'clock position. Bedside ultrasound revealed a mass. Magnetic resonance imaging showed a hemorrhagic 3×4 cm mass in the right perianal region pressing on and indenting the right aspect of the distal external sphincter. The mass was excised completely with local perianal incision over the mass at 11'o clock. Surgical pathology revealed an isolated endometrioma in the perianal area. CONCLUSIONS Isolated perianal endometrioma is a rare disease, with only 21 published cases. Its diagnosis is difficult to establish, and a wide range of tests is often needed. Laparoscopic or surgical intervention may be required in cases of rectal endometriosis for an accurate diagnosis. Careful history taking and examination along with a high index of suspicion are necessary to diagnose perianal endometrioma.

The present study aimed to descry the effectiveness of dried microalga Chlamydomonas sp. for disposing of arsenic from aqueous solution. The study included examining the impact of some factors on algae's adsorption capacity (optimization study), such as initial concentrations of heavy metal, biosorbent doses, pH and contact time. All trials have been performed at constant temperature 25 °C and shaking speed of 300 rpm. The optimization studying indicated the pH 4, contact time at 60 min, temperature 25 °C and biomass concentration of 0.6 g/l were the best optimum conditions for the bioremediation activity with maximum removal percentage 95.2% and biosorption capacity 53.8 mg/g. Attesting of biosorption by applying FTIR (Fourier transfigure infrared), XRD (X-ray diffraction), SEM-EDX (Scanning Electron Microscope - Energy Dispersive X-ray), DLS (Dynamic light scarring) and ZP (Zeta Potential) was conducted. Also, Kinetics, isotherm equilibrium and thermodynamics were carried out to explain the plausible maximum biosorption capacity and biosorption rate of biosorbent q maximum.
