Objectives: Comorbidities increase susceptibility to severe coronavirus disease 2019 (COVID-19) infections, but limited information has been published regarding human immunodeficiency virus (HIV) and COVID-19 co-infections. This study explored the relationships among socioeconomic characteristics, sexual behaviors, and COVID-19 infection rates among Korean men who have sex with men (MSM) who are also living with HIV. Methods: Data were collected through a web survey aimed at members of the largest gay portal site in Korea, supported by the National Research Foundation of Korea (n=1005). The primary independent variables included COVID-19-related vaccinations and sexual behaviors. The dependent variable was the incidence of COVID-19 infection among respondents during the pandemic. For statistical analysis, hierarchical multiple logistic regression was performed, controlling for potential confounding variables. Results: Model I indicated that older MSM were less likely to contract COVID-19 (adjusted odds ratio [aOR], 0.98; 95% confidence interval [CI], 0.96 to 0.99). Model II demonstrated that HIV-positive MSM were nearly twice as likely to be infected with COVID-19 compared to their HIV-negative counterparts (aOR, 1.97; 95% CI, 1.14 to 3.41). Furthermore, even after accounting for COVID-19 vaccination status in model III, HIV-positive MSM continued to show a higher risk of infection (aOR, 1.93; 95% CI, 1.12 to 3.35). Conclusions: The findings of this study indicate that HIV-positive MSM are at an increased risk of contracting COVID-19, even when their vaccination status is considered. Therefore, it is essential to prioritize the prevention of COVID-19 infections in HIV-positive individuals by administering appropriate antiretroviral therapy and ensuring adherence to public health guidelines.

A small scale survey was performed to know the infection status of intestinal parasite in children of the residential institutions and street communities in Metro Manila, Philippines. A total of 284 stool samples from 11 institutions and 3 street communities was examined by the formalin-ether concentration method. The scotch tape anal swab was adapted to 121 children to investigate the infection status of Enterovius vermicularis. It was found out that 62.0％ of the children examined were positive for one or more intestinal parasites. Multiple infections were observed in 34.2％ of the children. Among 172 children who gave detail information, the prevalence for Ascaris lumbricoides, Trichuris trichiura, and hookworm was 36.0％, 44.8％, and 7.0％ respectively. Of the children examined, 47.7％ were found to be harboring parasitic protozoans such as Entamoeba histolytica, Giardia lamblia, and Blastocystis hominis. The most prevalent of these protozoans was B. hominis with an infection rate of 40.7％. The prevalence of these infections among children living in institutions was relatively high. More efforts should be made to implement anthelminthic programs including bi-annual follow-up treatments.

Purpose: This study was done to determine the extent of Clonorchis sinensis infections as well as other parasitic infections and to determine the growth rate. Method: Analyzed test results were from 1,050 bowel samples taken at 3 public health subcenters located in Muju, North Jeolla Province during February and March 2007. Result: The results are summarized as follows; The egg positive rate by stool examination was 4.3%. Ascaris lumbricoides, Enterobius vermicularis, Clonorchis sinensis, Trichuris trichiura, Metagonimus, Paragonimus were detected. No one was infected with multiple parasites. Infection rate for Clonorchis sinensis was 3.5%. Statistical correlation to Clonorchis sinensis infection rate was as follows; Gender (p=0.001), Age (p=0.005), Proximity to a river (p<0.000), Drinking (p<0.000), Smoking (p=0.009), Cooking of freshwater fish (p<0.000), Confidence in subjective health status (p=0.032), Family history of infection (p=0.005), No significant correlation was found between Clonorchis sinensis infection rate and duration of stay (p=0.809) in the agricultural communities or between Clonorchis sinensis infection and knowledge of Clonorchis sinensis (p=0.113). Conclusion: The results of this survey show that there is a need to develop a program to test the condition of Clonorchis Sinensis infection and its growth rate in residents of rural communities.

Background: Human papillomavirus (HPV) infection is the main causes of cervical cancer in women worldwide. The goal of the present study was to determine the prevalence and distribution of HPV genotypes in women from Saudi Arabia. Recently, several HPV detection methods have been developed, each with different sensitivities and specificities. Methods: In this study, total forty cervical samples were subjected to polymerase chain reaction and hybridization to BioFilmChip microarray assessment. Results: Human papillomavirus (HPV) infections were found in 43% of the specimens. The most prevalent genotypes were HPV 16 (30%) HPV 18 (8.0%) followed by type HPV 45, occurring at 5.0%. Conclusion: Our finding showed the HPV infection and prevalence is increasing at alarming rate in women of Saudi Arabia. There was no low risk infection detected in the tested samples. The BioFilmChip microarray detection system is highly accurate and suitable for detection of single and multiple infections, allowing rapid detection with less time-consumption and easier performance as compared with other methods.

A serological survey was performed using ELISA to estimate the prevalence of tissue and luminal helminthic infections among hospital patients in Hanoi region, Vietnam. An overall seroprevalence of tissue and luminal helminthiases was 64.0% (95% CI 61.2-66.8) among 1,120 patients who visited Hanoi Medical University Hospital, Vietnam in 2018. The highest seroprevalence was observed against Toxocara spp. (59.0%), followed by Strongyloides stercoralis (46.3%), Gnathostoma spp. (25.5%), cysticercus (12.8%), Angiostrongylus cantonensis (10.5%), Fasciola spp. (11.1%), and Clonorchis sinensis (8.7%). Mono-infection by one species (11.1%) was lower than multiple infections (53.0%) (P<0.05). The seroprevalence in males (59.3%) was lower than in females (66.2%) but not statistically significant (P>0.05). Children (<15 years) revealed lower seroprevalence (34.0%) than adults (68.4%), and the age group 51-70 years revealed the highest seroprevalence (76.0%). Among the seropositive patients, eosinophilia (≥8.0%) was noted in 80.2%. The present results suggested active transmission of various tissue and luminal helminths among people in Hanoi, Vietnam.

The genotypes of Human Papilloma Virus (HPV) are important in the carcinogenesis of uterine cervical cancer. Diagnosis of uterine cervical cancer screening has been executed using Papanicolau method (Pap) and HPV DNA Chip method. We researched the interrelation of HPV DNA genotypes in single and multiple infections and analyzed the results of Pap and HPV DNA Chip tests at Gunsan Medical Center (GMC). The correlation analysis was surveyed on collected results from 599 patients who have been tested with both Pap and HPV DNA chip tests from November 2004 to May 2010 at GMC. The inconsistency between Pap and HPV DNA Chip tests was 41.1%. The HPV DNA Chip genotype related with high risk cases were type 16 (13.5%), type 52 (10.5%), type 58 (10.1%), and type 18 (3.4%). Those related with low risk cases were type 70 (8.9%), type 6 (1.7%), type 40 (1.2%), type 11 (1.3%), and other types (14.3%). Among the 195 cases of HPV positive status, 161 cases were associated with single infection; 108 (67.1%) cases were related with high risk genotype; 19 (11.8%) cases were low risk genotype; 31 (21.1%) cases were related with other types. 29 cases were associated with double infections; 23 (79.3%) cases were high risks; 5 (17.2%) cases were mixed high and low risks; 1 (3.5%) case was low risk.

Staphylococcus aureus is an important cause of human infections, and it is also a commensal that colonizes the nose, axillae, vagina, throat, or skin surfaces. S. aureus has increasingly been recognized as a cause of severe invasive illness, and individuals colonized with this pathogen are subsequently at increased risk of its infections. S. aureus infection is a major cause of skin, soft tissue, respiratory, bone, joint, and endovascular disorders, and staphylococcal bacteremia may cause abscess, endocarditis, pneumonia, metastatic infection, foreign body infection, or sepsis. The authors describe a case of a fisherman who died of sepsis on a fishing boat during sailing out for fish. The autopsy shows paravertebral abscess, pus in the pericardial sac, infective endocarditis with vegetation on the aortic valve cusp, myocarditis, pneumonia and nephritis with bacterial colonization, and also liver cirrhosis and multiple gastric ulcerations.

Quinolone antibiotics are frequently prescribed for suspected respiratory or urinary tract infections because of their effectiveness and generally perceived safety profile. On the other hand, some studies have raised concerns regarding the potential association between quinolone use and Achilles tendinopathy or tendon rupture. There is a lack of reports on the link between quinolone use and multiple tendon and tendon attachment site pain in the foot and ankle joints; hence, this study examined this issue further. This paper presents a case report of a patient with persistent Achilles tendinopathy and multiple tendon and tendon attachment site pain in the foot who did not respond adequately to conservative treatments. In particular, the discontinuation of quinolone use resulted in favorable clinical outcomes. This report offers valuable insights into the potential risks associated with quinolone antibiotics and highlights the importance of vigilance when managing patients with tendon-related complaints. A comprehensive review of the relevant literature is also presented to contextualize these findings.

This study explored epidemiological trends in trichomoniasis in Daegu, South Korea. Wet mount microscopy, PCR, and multiplex PCR were used to test for Trichomonas vaginalis in vaginal swab samples obtained from 621 women visiting 2 clinics in Daegu. Of the 621 women tested, microscopy detected T. vaginalis in 4 (0.6%) patients, PCR detected T. vaginalis in 19 (3.0%) patients, and multiplex PCR detected T. vaginalis in 12 (1.9%) patients. Testing via PCR demonstrated high sensitivity and high negative predictive value for T. vaginalis. Among the 19 women who tested positive for T. vaginalis according to PCR, 94.7% (18/19) reported vaginal signs and symptoms. Notably, more than 50% of T. vaginalis infections occurred in females younger than 30 years old, and 58% were unmarried. Multiplex PCR, which simultaneously detects pathogens from various sexually transmitted infections, revealed that 91.7% (11/12) of patients were infected with 2 or more pathogens. Mycoplasma hominis was the most prevalent co-infection pathogen with T. vaginalis, followed by Ureaplasma urealyticum and Chlamydia trachomatis. Our results indicate that PCR and multiplex PCR are the most sensitive tools for T. vaginalis diagnosis, rather than microscopy which has been routinely used to detect T. vaginalis infections in South Korea. Therefore, clinicians should take note of the high prevalence of T. vaginalis infections among adolescent and young women in order to prevent persistent infection and transmission of this disease.

Background: Anogenital warts (AGWs) are common results of sexually transmitted infection (STI). Human papillomavirus (HPV) types 6 and 11, which are non-oncogenic types, account for 90% of the clinical manifestations. Although the quadrivalent HPV vaccine has been launched, AGW remains prevalent in some countries and shows association with abnormal cervical cytology. Objectives: To study the prevalence of abnormal cervical cytology (low grade squamous intraepithelial lesions or worse; LSIL+) in immunocompetent Thai women newly presenting with external AGWs. Materials and Methods: Medical charts of all women attending Siriraj STI clinic during 2007-2011 were reviewed. Only women presenting with external AGWs who were not immunocompromised (pregnant, human immunodeficiency virus positive or being on immunosuppressant drugs) and had not been diagnosed with cervical cancer were included into the study. Multivariate analysis was used to determine the association between the characteristics of the patients and those of AGWs and LSIL+. Results: A total of 191 women were eligible, with a mean age of $27.0{\pm}8.9$ years; and a mean body mass index of $20.6{\pm}8.9kg/m^2$. Half of them finished university. The most common type of AGWs was exophytic (80.1%). The posterior fourchette appeared to be the most common affected site of the warts (31.9%), followed by labia minora (26.6%) and mons pubis (19.9%). The median number of lesions was 3 (range 1-20). Around 40% of them had recurrent warts within 6 months after completing the treatment. The prevalence of LSIL+ at the first visit was 16.3% (LSIL 12.6%, ASC-H 1.1%, HSIL 2.6%). After adjusting for age, parity and miscarriage, number of warts ${\geq}5$ was the only factor associated with LSIL+(aOR 2.65, 95%CI 1.11-6.29, p 0.027). Conclusions: LSIL+ is prevalent among immunocompetent Thai women presenting with external AGWs, especially those with multiple lesions.
