OBJECTIVE: Human papillomaviruses (HPVs) are among the agents responsible for infection and cancer of the skin and mucous membranes in the human body. The aim of this study was to investigate the frequency and type distribution of HPVs in married female patients with gynecological complaints, who had visited the Maternity Hospital in Erzurum, Turkey. METHODS: In this study, 263 cervical swab samples were taken from married women using the Pap smear method and were investigated for positive reactivity against HPV. The L1 gene region of HPV was investigated using molecular methods. For this purpose, polymerase chain reaction (PCR) assays and sequence analysis of positive samples were performed. Phylogenetic analyses were performed using a bioinformatics approach after sequencing. RESULTS: HPV-DNA was detected in 17 (6.5%) samples. Highest positive reactivity to HPV-DNA was found in the 35–44 age group at 9.2%. Fourteen out of seventeen positive samples were included in the phylogenetic analysis. All isolates clustered in the Alphapapillomavirus genus. Six samples were found to be HPV 70 positive, four were HPV 16 positive, and the rest were HPV 54, 72, 81, and 114 positive. When genotyping data were evaluated according to the risk group, we found that 28.6% of the 14 samples were found to be high risk-HPV, and 71.4% were low risk-HPV. CONCLUSIONS: As per our knowledge, this is the first report on the phylogenetic analysis of HPV genotypes isolated from women in Turkey. The prevalence of low- and-high risk HPV was determined in married women in Erzurum, and these results contribute to the epidemiological data on the distribution of HPV types for this region.

OBJECTIVES: The aim of this study is to investigate the efficacy of locally applied insulin-like growth factor 1 (IGF-1) on the recovery of facial nerve functions after crush injury in a rabbit model. METHODS: The rabbits were randomly assigned into three groups. Group 1 consisted of the rabbits with crush injury alone; group 2, the animals applied saline solution onto the crushed facial nerve and group 3, IGF-1 implemented to the nerve in the same manner. Facial nerve injury was first electrophysiologically studied on 10th and 42nd days of the procedure. The damage to the facial nerves was then investigated histopathologically, after sacrification of the animals. RESULTS: In the electrophysiological study, compound muscle action potential amplitudes of the crushed nerves in the second group were decreased. In pathological specimens of the first and second groups, the orders of axons were distorted; demyelination and proliferation of Schwann cells were observed. However, in IGF-1 treated group axonal order and myelin were preserved, and Schwann cell proliferation was close to normal (P < 0.05). CONCLUSION: Local application of IGF-1 in a slow releasing gel was found efficacious in the recovery of the facial nerve crush injury in rabbits. IGF-1 was considered worthy of being tried in clinical studies in facial nerve injury cases.

Patellar metastases are very rare. There have been approximately 20 cases reported in the literature. We have also noted two other reports of patellar metastasis from lung carcinoma as the first manifestation of lung cancer in our literature review. We present a case of patellar metastasis as the first manifestation of lung epidermoid carcinoma in a patient who was a smoker for 33 years.
