Cemento-Ossifying Fibroma With Cerebral Involvement.

Cemento-ossifying fibroma (COF) is a rare fibro-osseous tumor. The lesion is most commonly seen in people in the third and fourth decade. There are three variants of ossifying fibroma; juvenile trabecular ossifying fibroma, juvenile psammomatoid ossifying fibroma, and COF. COF is highly cellular and contains a fibrous tissue that has different amounts of calcified tissue. Although histologically benign, it has a significant growth potential.

A Giant Fronto-Ethmoidal Osteoma Presenting With Proptosis and Diplopia.

Osteomas are benign bone tumors commonly involving paranasal sinus walls. They are divided into three groups as ivory, mature, and mixed form. We reported demonstrative radiological features of an unusual case of giant osteoma presenting with proptosis and diplopia.

Membranous Nasopharyngeal Stenosis: Case Report.

Nasopharyngeal stenosis is a rare condition and occurs usually secondary to nasopharyngeal or oropharyngeal surgery and radiotherapy. It may cause obstructive symptoms in patients and is diagnosed usually with nasopharyngoscopy. Treatment is difficult and requires different surgical techniques including balloon dilatation. Even after a successful surgery, recurrence is very common.

The Use of Predictive Laboratory Tests in Rapid Triage of COVID-19 Pandemic Outpatient Clinic Patients.

BACKGROUND: Patients who come to the emergency pandemic outpatient clinic with a pre-diagnosis of COVID-19 are still a burden on the health system. Rapid triage of patients is important to reduce transmission. The aim of this study is to evaluate the biochemistry and hemogram results of real-time reverse transcription-polymerase chain reaction (RT-PCR) positive and negative patients in the emergency pandemic outpatient clinic and to investigate predictive values of the initial tests that will help to make rapid diagnosis. METHODS: Patients who applied to the emergency pandemic outpatient clinic with the suspicion of COVID-19 between November 01, 2020 and January 01, 2021 were evaluated with RT-PCR and laboratory examinations. RESULTS: A total of 551 patients were included in the study. The mean age of the patients was 50.31 ± 18.47 (min. 18 - max. 94), and 47.2% (n = 260) of the patients included in the study were male and 52.8% (n = 291) were female. In the comparison of hemogram parameters, we found that mean platelet volume (MPV) was significantly higher (p = 0.023), whereas white blood cell (WBC), platelet counts (PLT), lymphocyte and neutrophil values were significantly lower in RT-PCR positive patients (p < 0.001). There were no significant differences between the PCR positive and negative patients in terms of other parameters. In the comparison of biochemical parameters, we found that lactate dehydrogenase LDH (p = 0.001), creatinine (p = 0.002), and AST (p < 0.001) values were significantly higher in PCR positive patients, while there were no significant differences in terms of other biochemical parameters (p > 0.05). CONCLUSIONS: Our study results show that the practical quick-look hemogram and MPV can be used as a specially evaluated parameter in the rapid management of the first application COVID-19 patients. In addition, biochemically high levels of LDH and creatinine can be used to guide the clinician in terms of early hydration of the patient with a pre-diagnosis of COVID-19 to alleviate acute kidney damage.

Comparison of Clinical, Laboratory and Demographic Characteristics of Patients Diagnosed with COVID-19 as Symptomatic and Atypical Symptoms.

BACKGROUND: Clinical findings of COVID-19 have been observed with a wide spectrum ranging from asymptomatic disease and mild upper respiratory tract infection to severe viral pneumonia resulting in mortality. While clinical symptoms present in some COVID-19 patients, others have been incidentally identified. The objective of this study was to examine the clinical and laboratory features of patients diagnosed with COVID-19 who were symptomatic or had atypical symptoms and to make a contribution to the literature. METHODS: Patients with the likelihood of having COVID-19 pneumonia were evaluated with RT-PCR samples, other laboratory tests, and chest computed tomography. RESULTS: There were significant differences between these groups in terms of age, dyspnea, saturation, and comor-bidities including hypertension [HT] in 19 patients, cerebrovascular events [CVE] that were classified as other diseases in two patients (intracranial mass in one patient and Alzheimer's disease in one patient), and CRP and platelet counts (PLT) among the laboratory parameters (for all p < 0.05). CONCLUSIONS: Atypical symptoms have increased due to the progression of the outbreak. Infected people with atypical symptoms can act as sources of the infection. Therefore, the epidemiological history of these patients should be sought in detail, and individuals with atypical symptoms in society should be identified as soon as possible in order to control the spreading of the disease.
