Cervical cancer is the fourth most common cancer among women all over the world. It is accepted that cervical cancer is highly related to the HPV. The International Agency for Research on Cancer (IARC) has classified 13 HPV types as group 1 carcinogens (HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, and 66), which are commonly referred to as high risk-HPVs (hr-HPVs). Among these, hr-HPV-16 is undoubtedly the most carcinogenic based in the burden of cervical cancer (CC) and its precursor lesions. In our study, we analyzed retrospectively the data of a total of 2329 female patients who applied to the obstetrics and gynecology outpatient clinic of our hospital over a seven-year-period, whose cervical smear were carried out by the polymerase chain reaction (PCR) and cytology. In this study, it was aimed to determine the data of of HPV prevalence in our region during the seven-year-period from April 2014 to April 2021 and the most common genotypes and to interpret them together with the cervical smears cytology and biopsy results if it is available. HPV 3, 6, 11, 16, 18, 21, 26, 31, 33, 35, 39, 40, 42, 45, 51, 52, 53, 54, 55, 56, 58, 59, 61, 62, 66, 67, 68, 70, 72, 73, 81, 82, 83, 84 were identified by using linear array HPV genotyping test (Roche Diagnostics, Switzerland) from April 2014 to October 2017. HPV genotypes were identified by using HPV Genotypes 14 Real-TM Quant (Qiagen, Germany) between October 2017 and April 2021. This method detected HPV genotypes 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68. The data were analyzed using IBM SPSS Statistics (Version 25.0) predictive analytics software. Continuous variables are indicated as mean ± standard deviation, and discrete variables are indicated as number [percentage (%)]. Chi-square test is used to investigate dependencies between variables. All analyzes were evaluated to provide 95% confidence level and 80% test power. p<0.05 was accepted as significant for the analysis results. Out of 2329 patients, 1283 were found to be HPV negative (54.6%) and the others were found to be HPV positive (45.4%) by using real-time PCR in the cervical smears. It was detected that out of 1046 HPV positive patients, 585 of them (55.9%) had one HPV genotype and 461 of them (44.1%) had more than one HPV genotypes. As we divided all of the patients into two groups as <30 (Group I) ve > 30 (Group II) according to age range, HPV positivity was found 134/296 (45.2%) in Group I and 912/2033 (44.8%) in Group II. When we compared the HPV positive/negative results of Groups I and II by using chi-square test, no significant difference was found between the two age groups in terms of HPV positivity (p= 0.894). In our study, the most common HPV types were HPV 16 (14.2%), HPV 68 (8.2%), HPV 56 (8.2%), HPV 52 (7.1%), HPV 51 (6.8%), HPV 31 (6.5%), HPV 66(6.1%), HPV 39 (5.8%) and HPV 18 (5.6%) among the women with normal and abnormal cytology in the cervical smears. ASC-US was the most common abnormal epithelial cell change detected with HPV16 and 18 genotypes and it was detected 26.07% and 21.88% in patients, respectively. In our study, we found HPV prevalance in our region as 45.4% and the most common type was HPV 16. As a result, we concluded that it is important to determine regional HPV prevalance data, which is an important step in cervical cancer prevention strategies, and regional data of detected HPV genotypes.

[Two Case of Rhino-Orbito-Cerebral Mucormicosis Developed After COVID-19 Infection]. / COVID-19 Enfeksiyonu Sonrasi Gelisen Iki Rino-Orbito-Serebral Mukormikoz Olgusu.

Coronavirus 2019 (COVID-19) infection causes excessive cytokine response and a decrease in cellular immune response and this increases susceptibility to fungal co-infections. Mucormycosis is a rare, lifethreatening invasive fungal infection. In this report, two cases who developed rhino-orbito-cerebral mucormycosis shortly after having COVID-19 infection were presented. The first case was a 68-year old woman who admitted to our clinic with orbital cellulitis in her left eye and had a known diagnosis of asthma and rheumatoid arthritis. She was diagnosed with COVID-19 pneumonia 40 days ago, stayed in the intensive care unit for a long time, and received pulse steroid (1000 mg methylprednisolone), interleukin-1 (IL-1) inhibitor (anakinra) and broad-spectrum antibiotic treatments together with antiviral therapy during this period. The second case was a 63-year-old male patient with known diabetes mellitus, hypertension and retinitis pigmentosa, with a history of hospitalization in the intensive care unit due to COVID-19 pneumonia 20 days ago and received pulse steroid therapy during this period. He admitted to our clinic with the complaints of droopy right eyelid, swelling, nausea and vomiting. In both cases, paranasal sinus tomography findings were consistent with invasive sinusitis. Functional endoscopic sinus surgery was performed immediately in less than 16 hours from the first admission in both cases. Histopathological examination of the both cases revealed results consistent with mucormycosis. Mucorales spp. was isolated in sinus tissue culture of the second case taken during the operation. Both of the patients received liposomal amphotericin B. First case died on the 19th day of the treatment. Second case was discharged with full recovery after nine weeks of treatment. The suppression of cellular immunity during the COVID-19 infection, and the use of steroids and interleukin inhibitors in the treatment of severe cases may increase secondary invasive fungal infections. Therefore, clinicians should more frequently consider possible fungal infections in patients with COVID-19.

Evaluation of in vitro activity of ceftaroline, ceftobiprole and their combination with trimethoprim/sulfamethoxazole against MRSA isolates: a two center study.

There is an increasing need for new synergistic antimicrobial combinations against multidrug-resistant bacteria. Our objective was to evaluate the activity of ceftaroline, ceftobiprole and their combination with trimethoprim/sulfamethoxazole against methicillin-resistant Staphylococcus aureus (MRSA) isolates recovered at two centers in Turkey. Activities of ceftaroline and ceftobiprole were tested against 100 MRSA isolates using gradient diffusion method. Activities of ceftaroline and ceftobiprole in combination with trimethoprim/sulfamethoxazole against 20 selected isolates (including all isolates that were non-susceptible to ceftaroline or ceftobiprole, and randomly selected isolates) were investigated using MIC:MIC ratio method. Antimicrobial interactions were interpreted using the fractional inhibitory concentration (FIC) index. The MIC50/MIC90 values for ceftaroline and ceftobiprole were 0.75/1 and 1/1.5 mg/L, respectively. Ceftaroline and ceftobiprole susceptibility rates among 100 MRSA isolates were 94% and 96%, respectively. Ceftaroline, ceftobiprole and trimethoprim/sulfamethoxazole MICs of isolates were not increased when ceftaroline or ceftobiprole was combined with trimethoprim/sulfamethoxazole. Ceftobiprole- trimethoprim/sulfamethoxazole combination demonstrated additivity against 35%, whereas ceftaroline- trimethoprim/sulfamethoxazole combination demonstrated additivity against 10% of 20 MRSA isolates. The remaining interactions for MRSA isolates were indifference. Three (75%) of four ceftobiprole-resistant isolates became susceptible to ceftobiprole after adding trimethoprim/sulfamethoxazole. None of the ceftaroline non-susceptible isolates became susceptible to ceftaroline after adding trimethoprim/sulfamethoxazole. Ceftobiprole- trimethoprim/sulfamethoxazole combination may be a better treatment option than ceftaroline- trimethoprim/sulfamethoxazole combination for MRSA infections. Clinical studies are needed to confirm the results of our in vitro study.
