The in-vivo anti-inflammatory effect of red earthworm (Lumbricus rubellus) ethanolic extract from organic farmland in Bali, Indonesia

Background: One of the typical responses to the protection of the body is inflammation. Extensive and severe inflammation can result in tissue damage. Earthworms have been used empirically for years to treat diseases that are based on inflammatory events. This study evaluates the anti-inflammatory properties of red earthworm (Lumbricus rubellus) ethanolic extract from organic farmland in Bali, Indonesia.

Methods: An experimental study by post-test only control group design was conducted among 30 adult male Wistar rats, divided into 6 groups. Each group was given 0.5% NaCMC (negative control), Diclofenac sodium 9 mg/kgBW (positive control), Red earthworm ethanolic extracts of 50 mg/kgBW (P1) and 100 mg/kgBW (P2) at 1 hour before carrageenan injection. In addition, the ethanolic extracts of Red earthworms, respectively 50 mg/kgBW (P3) and 100 mg/kgBW (P4), which had been given once a day, during 1 week before and at the eighth day 1 hour before carrageenan injection. The measurements of edema were performed 4 hours after the administration of the test material. Data were analyzed using SPSS version 20 for Windows.

Results: The median score of Rats Hind Paw Edema was 0.3 (0.2-0.4) ml in negative control, 0.1 (0.0-0.2) ml in positive control, 0.2 (0.1-0.2) ml in P1, 0.2 (0.1-0.3) ml in P2, 0.2 (0.1-0.2) ml in P3, and 0.1 (0.1-0.2) ml in P4 groups. There was a significant differences between the NaCMC group (negative control) with the Diclofenac sodium group (positive control), P1, P3, and P4 groups (p<0.05), but not with P2 group (p>0.05).

Conclusion:  We conclude that red earthworm (Lumbricus rubellus) ethanolic extract from Bali's organic farmland exhibits an anti-inflammatory effect.

Correlation of plasma vitamin d receptors with the severity of psoriasis vulgaris

Introduction: Psoriasis vulgaris is still a major problem in the field of dermatology. Until recently, the exact cause of psoriasis is still being debated. In recent years research has been carried out on vitamin D and its role in the immune system, especially in psoriasis. Vitamin D cannot be separated from the role of VDR. The study aims to evaluate correlation between VDR plasma levels and the severity of psoriasis vulgaris.

Method: Study design using a cross-sectional design to determine the correlation of vitamin D levels in plasma with the severity of psoriasis vulgaris calculated using the Psoriasis Area and Severity Index (PASI) score.

Result: This study included 47 study participants who had psoriasis vulgaris, consisting of 30 (63.8%) men and 17 (36.2%) women with a mean age of 44.66 years. The mean PASI score was 6.904, while the mean plasma VDR level was 30.328 ng/ml. Spearman correlation shows a strong negative correlation (r = - 0.979; p <0.001) between plasma VDR levels and PASI scores in psoriasis vulgaris patients.

Conclusion: Vitamin D plays a role in regulating the growth and differentiation of keratinocytes and influences dendritic cells and T lymphocytes' immune function so that low vitamin D levels have essential implications in the pathogenesis of psoriasis vulgaris. In performing its function, vitamin D must bind to VDR and form a complex. In this study, it was found that there was a strong negative correlation between plasma VDR levels and PASI scores, so it can be concluded that low plasma VDR levels correlate with high degrees of psoriasis vulgaris severity and vice versa.

Correlation between malondialdehyde levels and disease activity in vitiligo

Background: Vitiligo is an acquired depigmented skin disease that occurs due to the death of melanocytes. There are various presumed theories about the cause of melanocyte death in vitiligo; one of them is oxidative stress theory. Lipid peroxidation is the primary manifestation of oxidative stress, producing malondialdehyde (MDA) as its end product. Malondialdehyde is a stable marker to assess the occurrence of oxidative stress. This study aims to prove the differences in serum MDA levels in the active vitiligo, stable vitiligo, and normal control groups.

Method: This research is an analytical cross-sectional study involving 64 vitiligo patients with active and stable lesions and 20 normal controls. The study was conducted at Sanglah General Hospital Denpasar in February - November 2019. Serum MDA levels were measured to assess oxidative stress. The measurement of MDA levels was carried out by a spectrophotometer instrument using Competitive-ELISA method.

Results: In this study, there were significant differences in MDA levels between active, stable vitiligo patients, and control group (p=0.000) with active vitiligo type have the highest MDA mean, followed by stable type and control group respectively.

Conclusion: Increased serum MDA levels are an indicator of oxidative stress in vitiligo, which leads to melanocyte death and manifests as increased vitiligo disease activity. The results of this study support the role of oxidative stress in vitiligo pathogenesis and the use of oxidative stress indicators like serum MDA levels as biomarker in evaluating vitiligo disease activity.

High c-reactive protein level as risk factors of complications in upper gastrointestinal bleeding

Purpose: Upper gastrointestinal bleeding is the major medical emergency case in the field of gastroenterology. The complications of UGI bleeding are recurrent bleeding and death. Identifying risk factors for the complications is expected to prevent or reduce recurrent bleeding complications and deaths from UGI bleeding. This study aims to know the risk of UGI bleeding complications in patients with a high level of C reactive protein (CRP).

Patients and methods: A prospective observational analytic study was performed, including all UGI bleeding patients (variceal and nonvariceal). CRP level was used to determine the high-risk cohort. High-risk cohort if the CRP level 5 mg/L and above, and low risk if CRP level less than 5 mg/L. The outcome of the study was the incidence of complication, both rebleeding and death during follow up for six weeks. 

Results: Based on the characteristic data of the sample, the high-risk group appears to have a slightly older age, higher leucocyte count, lower hemoglobin levels, and higher serum creatinine than the low-risk group. The incidence rate of complication in the high-risk group was 85.3% while in the low-risk group was 37.5%, and the relative risk (RR) was 2.27 (95% CI: 1.43-3.67). There were significant differences in the incidence of complications between the group, X²: 16; p <0.001. The RR for rebleeding in the high-risk to low-risk cohort was 2.68 (95% CI: 1.31-5.47); this difference is statistically significant (X²:9.3; p=0.02). The RR for death complication was 1.70 (95% CI: 0.63-4.53), and the difference is not statistically significant (X²: 1.2; p=0.28).

Conclusion: In this study, we found the CRP level ≥ 5 mg/L as a significant risk factor for rebleeding complications but not mortality in a patient with UGI bleeding.

In vitro study comparison of purple leaf extract as denture cleanser at different concentration towards S. mutans growth on flexible denture

Background: The denture usage should be accompanied by good denture cleansing to prevent denture damage and oral disease due to bacterial on the denture. Research on purple leaves (Graptophyllum pictum) showed that purple leaves have anti-bacterial and antimicrobial activity. So it is essential to study the effectiveness of purple leaves as denture cleanser towards the growth of S. mutans on flexible denture plates.

Objective: The objective of the study was to compare the effectiveness of purple leaf extract at different concentrations: 1.25%; 2.5%; 10% and 40%, fittident^Ò and aquadest towards S. mutans growth on flexible denture plates.

Methods: This study was in vitro study that used S. mutans from local isolates of the microbiological laboratory faculty of medicine, Universitas Udayana. The isolates were incubated for 24 hours with temperature 37^oC on 18 plates (10x10x2mm). The concentration of purple leaf extract was 1.25%; 2.5%; 10% and 40%. The effectiveness of purple leaf extract, fittident^Ò and aquadest towards the growth of S. mutans can be evaluated from the number of S. mutans colonies on flexible denture base plate (CFU/ml). Data were analyzed using the One Way Anova test with 95% confidence level (α = 0,05%). LSD (Least Significant Different) was tested to determine the significance of differences in the treatment group. 

Result: The lowest mean of colonies' growth was found in 10% concentration (21.0000). There was significant difference in colony count between the extract concentration groups (p=0.000). LSD-multi comparisons test on the Post Hoc analysis showed a significant difference between the extract concentrations of 1.25% to 10% (p=0.037), and the 2.5% extract to 10% (p=0.012) and 40% (p=0.027). Graptophylum pictum extract showed with highest flavonoid content (4340,30 mg/100 QE wb).

Conclusion: All extract concentrations are effective in suppressing bacterial growth. The optimum concentration to the growth of S. mutans was the extract with 10% concentration but did not differ significantly with the 40% concentration extract.  

Risk scoring in predicting preterm birth of women receiving cervical cerclage

Background: Cervical incompetence is primarily a clinical diagnosis, which is characterized by recurrent painless dilation of cervix and spontaneous second trimester loss and preterm delivery. Despite recent advances, the indications and efficacy of cervical cerclage have been remained controversial. This study was performed with the aim of evaluating the risk factors of preterm birth among women who underwent cervical cerclage and establishing a scoring system to predict preterm labor in this group of women.

Material and Methods: This retrospective cohort study was performed on 95 women who had undergone cervical cerclage from January 2016 to January 2018 in Maternity Teaching Hospital of Sulaimaniyah, Iraq. A total of 66 women who delivered after 34 weeks were used as control group, compared to 29 cases who delivered before 34 weeks.

Results: According to the findings of the present study, there was a significant association between the preterm birth before the 34 weeks of pregnancy and the risk factors of pathological vaginal discharge, cervical length less than 25 mm prior to cerclage placement, and passive smoking. The positive predictive value was calculated using the prediction model was %99 with a risk score of 3, 47.6% with risk score 2 and 28.2 % with risk score 1.

Conclusion: The prediction model can be used as a tool to identify patients at a higher risk for PTD <34 weeks and to recognize those that could benefit from cerclage and deliver after 34 weeks. It could also be a useful tool for identifying those high risk women with cerclage who require increased surveillance.

The functional and physical state of the anal sphincter complex in the patients with rectal prolapse in the post-surgery period

Purpose: The work was aimed at comparative studying of the functional and physical state of the patients with rectal prolapse after surgical treatment with various surgical techniques and at identifying the most optimal procedure technique.

Patients and methods: The authors observed 49 patients (32 women, or 65.3 %) aged 22 — 83 years (the median age of women was 46.1 ± 1.3 years old, of men — 48.7 ± 1.4 years old) with the rectal prolapse of varying severity. The Delorme’s procedure was indicated for 28 patients (57.1 %). Perianal proctosigmoidectomy (the Altemeier’s surgery) was performed in 12 patients (24.5 %). In the young patients, preference was given to the Ripstein’s abdominal surgery (nine patients; 18.4 %). To objectively assess the physical state of the anal sphincter apparatus, traditional sphincterometry was performed using S4402 sphincterometer with a nonperfusing sensor (Pro Medika GmbH, Germany), and the functional state of the sphincter complex was subjectively assessed using the Wexner’s score scale.

Results: The best results were obtained after the Delorme’s procedure (p<0.05), while the worse results were obtained in the young patients after the Ripstein’s surgery (p<0.05).

Conclusion: The obtained results may be used for assessing the functional and physical state of the anal sphincter complex in the surgical treatment of the patients with the rectal prolapse syndrome, especially in those with ASFs of varying severity.

Correlation between postherpetic neuralgia (PHN) patients’ stress level and the quality of life of their families in Universitas Sumatera Utara Hospital

Background: Postherpetic neuralgia (PHN) is the most common complication seen in herpes zoster patients. Its clinical manifestations consist of persisting sharp pain even when the initial exanthema has disappeared. These patients experienced stress from the conditions and from the treatment process, which in turn affect their families’ quality of life.

Patients and Methods: This study was an observational analytic study with a cross-sectional design involving 30 PHN patients and their families. Patients were required to fill out the Perceived Stress Scale (PSS-10) questionnaire to assess their stress levels. Their respective families were required to fill out the Family Dermatology Life Quality Index (FDLQI) questionnaire to assess their quality of life. Statistical analysis was performed on both data with the Spearman correlation test (data were not normally distributed). ANOVA test was performed to assess the average difference between the stress levels experienced by PHN patients and the quality of life of their families.

Results: The families of PHN patients who experienced severe stress levels had worse or lower quality of life compared to the families of patients with moderate or mild stress levels. The lowest average score of quality of life is 27.20 (severe stress level) and the highest average score of quality of life is 14.33 (mild stress level).

Conclusions: The stress level of PHN patients was significantly related to the quality of life of their respective families in the aspects covered in the FDLQI questionnaire (p <0.005). There was a significant difference in the family's quality of life score based on the patient's stress level (p<0.001)

Correlation between body mass index with striae in female adolescent

Background: Striae has been reported as a skin problem often experienced by a woman and becomes an aesthetic problem. This skin problem can occur at any age, including adolescents, even though it is more common in younger women. Some conditions increase the risk of striae, such as weight, pregnancy, puberty, and hormonal drugs. Women with higher body mass index (BMI) tend to have more striae. With a limited study on striae, it is quite interesting to evaluate the high incidence of striae in the population.

Patients and Methods:  This was a cross-sectional study using a total sampling method. The study was conducted after approval from the Ethics Committee Faculty of Medicine, Universitas Sumatera Utara. Samples are 155 female students aged 18-25 years old from the Medical Faculty of Universitas Sumatera Utara. All samples were physically examined to diagnose the striae, and the BMI was calculated.  All the collected data were analyzed statistically with ETA statistical tests to see the relationship between BMI and striae. P-value <0.05 considered statistically significant.

Results: The dominant age of the subject is 19 years old (62.5%), followed by 20 years old (30.3%), 21 years old (3.8%), and 18 and 23 years old (0.6%). Out of 155 subjects, there are 117 have striae (75.5%). None of the striae subjects is underweight, normal weight was 113, 3 obese and one overweight. The 38 subjects without striae are in normal BMI. An analysis using ETA proved that BMI is not significantly associated with striae (p>0.05).

Conclusion: There is no significant relationship between BMI and striae.

Prevalence of and risk factors associated with anal HPV infection among men who have sex with men in Bali, Indonesia

Background: Anal human papillomavirus (HPV) is one of the most common sexually transmitted infection. Men who have sex with men (MSM) are commonly affected by anal HPV infection. Until now, there is no data available on the prevalence of HPV genotype in the MSM in Indonesia

Purpose: This study aimed to determine the prevalence and risk factors of anal HPV infection among MSM in Bali, Indonesia.

Patients and methods: A cross-sectional study was conducted among MSM in Sanglah Hospital, Bali, Indonesia. Blood samples were collected for HIV serological testing and syphilis serological screening, and anal swabs were collected for HPV genotyping. Risk factors associated with anal HPV infection were assessed by univariate and multivariate logistic regression. Anal HPV infections were also being categorized into any anal HPV types, HR HPV types, LR HPV types, and multiple HPV types.

Results: Mean age of participants was 31.4 years. The prevalence of HPV infection was 89.3% and 61.3% for coinfection between LR and HR types. Almost half of our participants had at least two HR anal HPV and they were co-infected with HPV 16, 39, and 51. Participants with HIV infection were associated with anal HPV, LR HPV, and multiple HPV types of infections.

Conclusion: HIV status were associated with anal HPV infection among MSM in Bali, Indonesia. Since all of the participants with at least two anal HPV genotypes were co-infected with HPV 16, 39, and 51, it is to be hoped that HPV vaccination can be introduced into MSM communities in Bali, Indonesia.

Potential development of turmeric extract nanoparticles as a topical anti-inflammatory agent

Turmeric is the most commonly studied herbal ingredient because it has antioxidant, anti-inflammatory, antimicrobial, and anticancer activity. Considering that most inflammatory skin diseases are localized, it is considered that the topical application of turmeric extract can be beneficial because it has a local effect on the skin. The topical application of turmeric extract has limitations because the active ingredient content of curcumin (CUR) has poor solubility in water, low absorption, and rapid elimination of metabolites, which results in low bioavailability of the drug. Recent studies have focused more on nanoparticle formulations that can improve the stability and bioavailability of CUR.

Spontaneous conversion to sinus rhythm in atrial fibrillation after dual antiplatelet and anticoagulant therapy in patients with unstable angina

Introduction: Atrial fibrillation (AF) is a common arrhythmia and often becomes persistent with a high risk of thromboembolism event. Spontaneous conversion to sinus rhythm can occur in 50% of cases with new-onset AF. In this case report we report the spontaneous conversion of AF to sinus rhythm in patients with Unstable Angina without any thromboembolic complications.

Case description: A 65-year-old man with unstable angina pectoris (UA) with new-onset atrial fibrillation normal ventricular rate (AF-NVR) came to the Emergency Department Bali Mandara General Hospital. Patients have a history of uncontrolled hypertension and active smokers. Standard management of UA using dual antiplatelet, nitrates, and anticoagulants was given to this patient. There were no anti-arrhythmia drugs given to seek for AF cardioversion. Within 6 hours after initial therapy, spontaneous conversion of AF to sinus rhythm occurs. The patient was treated for five days in a stable condition without thromboembolic complications. Long-term anticoagulants were not given to patients because the CHA₂DS₂-Vasc score is less than two indicating a low risk of thromboembolism.

Conclusion: New-onset AF has the chance of spontaneous conversion to sinus rhythm within 48 hours, proper management of the trigger factors of AF and optimal rate control are determinants of prognosis. Provision of long-term anticoagulants must be based on the CHA₂DS₂-Vasc score.

Case description: a 24-year-old woman who will undergo labor with a history of VWD.  The patient was planned for induction of vaginal delivery and has been given intranasal desmopressin, cryoprecipitate, and factor VIII from before delivery to 5 days after delivery. Labor occurs without excess bleeding. The patient was monitored for 6 days after delivery, and there is no complication of excessive bleeding.

Conclusion: This case emphasizes how to manage Von Willebrand's disease in pregnancy with limitation in the examination and therapeutic option, also the importance of joint management from the hematologist, obstetrician, starting from the antepartum, delivery, and postpartum phases.

Uterine cervix mixed adenoneuroendocrine carcinoma: case report of a rare, high grade and aggressive tumor

Introduction: Neuroendocrine carcinoma of the uterine cervix is a rare type of cancer in the female reproductive system, accounting for only about 1% of all malignancies in the uterine cervix. Mixed Adenoneuroendocrine Carcinoma (MANEC) is a combination of neuroendocrine components and non-neuroendocrine components, with each component contribute >30% of the tumor cells. This rare type of tumor is aggressive, high recurrence rates, and early distant metastases.

Case description: A 37-year-old female patient referred for evaluation after a previous finding of a cervix mass and a clinical diagnosis of cervical carcinoma IB2. Ultrasonography examination concluded a cervical mass, suspicious of malignancy. On macroscopic examination, it was found white-grey colored, huddle, and brittle mass filled the entire cervix with a size of 5x4 and 5x1 cm. Routine histopathological examination shows neoplastic cells forming a trabecular pattern, organoid, part with rosette formation, infiltrative between the connective tissue and a large area of necrosis. These cells conform to a uniform morphology, small oval to round nucleus, partially composed of molding, narrow cytoplasm, salt and pepper chromatin, and mitotic figure > 25/10 HPF. At some other focus, neoplastic cells appear cribriform, solid, and tubular, with a round to oval hyperchromatic nuclei, increased N/C ratio, severe nuclear pleomorphism, eosinophilic cytoplasm, mitotic figure 5/10 HPF. The metastatic cell was found in four right pelvic lymph nodes, and five left pelvic lymph nodes. Immunohistochemistry examination of chromogranin-A and CEA shows positive, focal distribution on tumor cells cytoplasms. Synaptophysin shows positive, diffuse distribution on tumors cell cytoplasm. Ki-67 was positive in 90% malignant cell nuclei.

Coronavirus disease 2019 (COVID-19): A case report in a patient with diabetic ketoacidosis and hypertension

Background: Until May 2020, Indonesia is still on COVID-19 emergency status. South Jakarta is part of the Special Capital Region of Jakarta that has applied large-scale social restrictions. The Indonesian government has extended Jakarta's large-scale social restrictions to Friday, May 22^nd, 2020 to curb the spread of the corona-virus that causes COVID-19.

Case report: Patients with diabetic ketoacidosis and hypertension were infected with SARS-CoV-2. He had traveled from Saudi Arabia a week before and already has a fever. Arriving in Indonesia, the patient showed symptoms of worsening disease, experienced coughing, shortness of breath, and sore throat. The patient does not inject insulin due to loss of appetite. On March 30^th, 2020, a laboratory examination showed high blood sugar levels (369 mg/dL) followed by positive ketones bodies. On April 2^nd, 2020, the patient was designated as a confirmed case of COVID-19 after a positive polymerase chain reaction test. The rapid diagnostic test also showed a positive IgM.  Management of patient includes giving O₂ through the non-rebreathing oxygen mask, infusion of sodium chloride, 20 IU Apidra®, 12 IU Lantus® injection, Oseltamivir orally, Levofloxacin, Paracetamol, Vitamin C, Candesartan, Concor. This therapy was continued until April 5^th, 2020. On April 5^th, the patient complained about a cold sensation all over his body. The patient died on the afternoon of April 6^th, (8 days of hospitalization) due to sudden cardiac arrest and acute respiratory distress syndrome. Cardiopulmonary resuscitation was done with standardized protocol with no avail.

Conclusion: Diabetic ketoacidosis and hypertension worsen the condition of COVID-19 patients. There are many unknown disease progression outcomes in these patients.

Ruptured ectopic pregnancy management in the COVID-19 pandemic era: a case report

Introduction. COVID-19 protocol and the unavailability of proper instruments in the isolation room had complicated the usual protocol to diagnose and manage the medical and surgical conditions.  This article is about the first ruptured ectopic pregnancy cases encountered during the COVID-19 pandemic in Sanglah General Hospital. Considering the unique circumstances and the difficulty during establishing the diagnosis and conducting the management, we ought to present our experience through this article.

Case Description. This case report reviews a 24-years-old female, an asymptomatic COVID-19 case, who was diagnosed with ruptured ectopic pregnancy during appendectomy surgery in Sanglah General Hospital, Denpasar, Bali-Indonesia. The patient complained about mild lower right abdominal pain, with a clinical picture that supports acute appendicitis. However, the history taking revealed a history of post-curettage 15 days prior to admission due to vaginal bleeding suspected for incomplete abortion. Except for a positive pregnancy test, the clinical picture did not support a pregnancy nor a ruptured ectopic pregnancy. We still consider an ectopic pregnancy as no histopathological examination result was available to supports the previous vaginal bleeding was an intrauterine pregnancy. Further to complicate the problem, the patient was reactive for the COVID-19 screening test, thus requiring a COVID-19 protocol. As an ultrasound device was unavailable at the time in the isolation room, we could not assess for extrauterine pregnancy. Only during the surgical procedure for appendectomy, our surgical college notified us of the accompanying presence of sign of ruptured right ampullary pregnancy.

Conclusion. The COVID-19 isolation protocol and the unavailability of essential equipment and diagnostic tools in the isolation room could hinder the usual protocol used to diagnose and manage various medical and surgical problems. We hope this article could illustrate how COVID-19 had complicated unusual cases, thus reflect how important clinical judgment and infrastructure in our health care system.
