Abstract
BACKGROUND Subacute and chronic long-term effects of coronavirus disease 2019 (COVID-19) in different organ systems have been studied in post-COVID patients recently. COVID-19 may cause gastrointestinal (GI) system findings due to the presence of its receptor, angiotensin converting enzyme type 2 (ACE2), which is extensively expressed in the GI tract. In this study, we aimed to evaluate the post-infectious histopathological alterations of COVID-19 in pediatric patients who had GI symptoms. METHODS Fifty-six specimens of upper endoscopic biopsies (including esophagus, stomach, bulbus and duodenum) obtained from seven patients and 12 specimens of lower endoscopic biopsies obtained from one patient who had GI symptoms after having COVID-19 (proven by polymerase chain reaction [PCR]) were evaluated as the study group. Forty specimens from five patients presenting with similar complaints but without COVID-19 were selected as the control group. All biopsy materials were immunohistochemically stained with the anti-SARS-CoV-2S1 antibody. RESULTS In all biopsies of the study group, anti-SARS-CoV-2S1 antibody was detected with moderate cytoplasmic positivity in epithelial cells and inflammatory cells in the lamina propria. No staining was observed in the control group. Epithelial damage, thrombus, or no other specific findings were detected in the GI tract biopsies of any of the patients. CONCLUSIONS The virus antigen was detected immunohistochemically in the stomach and duodenum, but not in the esophagus, even months after infection and causes gastritis and duodenitis. No specific histopathological finding was observed from non-COVID-19 gastritis/duodenitis. Therefore, the post-COVID-19 GI system involvement should be kept in mind in patients presenting with dyspeptic symptoms even if several months have passed.

Abstract
OBJECTIVES In the present study, we aimed to investigate the effect of dexpanthenol on wound healing at the histopathological level on cavernous tissue. MATERIALS AND METHODS Forty-four Wistar albino rats weighing 220-250 g were used. The rats were randomly divided into four groups as Group B, Group S, Group LD, and Group SD. In Group B, the incision was not repaired and left to secondary healing. In Group S, the incision line was repaired with 5/0 polyglactin suture. In Group LD, 0.25 mg/kg dexpanthenol was applied subcutaneously below the repaired wound region once a day during 14 days. In Group SD, 500 mg dexpanthenol was applied intraperitoneally once a day during 14 days. RESULTS No fibrosis was observed in 8 (80%) rats in group SD. Fibrosis rates were significantly lower in Group SD compared to Group B, Group S, and Group LD (p = 0.013, p = 0.005, and p = 0.003, respectively). CONCLUSION Systemic dexpanthenol administration significantly decreased fibrosis in penile fracture model on rats.

Abstract
Ghrelin is known to have effects on proliferation and differentiation of osteoblasts and improvement of bone mineral density in rats. However, no experimental research on ghrelin's effects on fracture healing has been reported. In this context, the effect of ghrelin on the union of femoral shaft fractures was examined in this study by evaluating whether ghrelin will directly contribute to fracture healing. Forty male Wistar-Albino rats were divided into two groups as control and experimental (ghrelin treated) and standard closed shaft fractures were created in the left femurs of all rats. Daily ghrelin injections were applied to the experimental groups and equal numbers of rats were killed after 14 and 28 days following fracture formation. Tissue samples were examined with radiological, biomechanical, biochemical and histological analyses. Densitometry study showed that bone mineral density was improved after 28 days of ghrelin treatment compared to control. On histological examination, at the end of the 14 and 28 days of recovery, significant union was observed in the ghrelin-treated group. The ghrelin-treated group had higher breaking strength and stiffness at the end of 28 days of recovery. Biochemically, ALP levels were found to be higher in the ghrelin-treated group at the end of 28 days of recovery. Results showed that ghrelin directly contributes to fracture healing and it is promising to consider the effect of ghrelin on fracture healing in human studies with pharmacological applications.

Abstract
BACKGROUND/AIMS Today, invasive diagnostic tests are necessary for definite diagnosis of adult celiac disease (CD). However, in selected children patients, the need for invasive tests is ceased. In this study, we evaluated adult patients according to the ESPGHAN (European Pediatric Gastroenterology Hepatology and Nutrition Society) criteria. METHODS Thirty-nine patients (aged 17-66) with symptoms of CD were included. Serum samples were tested for total IgA, tTG-IgA (antitissue transglutaminase), tTG-IgG, DGP-IgA (antideamidated gliadin peptide), DGP-IgG, and EMA (endomysial antibodies). HLA-DQ typing was studied with PCR-SSP (sequence-specific primers) method. Biopsy samples were evaluated according to Marsh scoring. RESULTS In CD patients, 71.4% (15/21) of the patients were diagnosed without biopsy according to the EPSGHAN criteria but when ESPGHAN's IgA tTG threshold value for children was taken into consideration (>200 IU/mL), the sensitivity decreased to 81%. Celiac disease diagnosed and control groups were compared in terms of HLA tissue types. DQ2.5 homozygous or DQ2.5/DQ2.2 was significantly higher in CD group, and DQ2- or DQ8-negative HLA tissue type was significantly higher in control group. CONCLUSION When serological tests, HLA typing, and clinical symptoms are all in favor of CD, biopsy may not be performed in selected adult CD patients.

Abstract
Alkaptonuria is a hereditary disorder of phenylalanine and tyrosine, with an incidence of approximately 1/200,000 to 1/1,000,000. Ochronosis is the accumulation of homogentisic acid and its metabolites in connective tissues such as the tendons, cartilage, and skin. In the present case study, a 50-year-old male presented with a nontraumatic calcaneal avulsion without a previous diagnosis of ochronosis. To the best of our knowledge, little information has been reported of this pathology in the Achilles tendon and the surgical management.

Abstract
OBJECTIVE Endometriosis is a chronic inflammatory disease pathologically defined as the presence of endometrial-like tissue outside the uterine cavity. It is one of the most important diseases affecting women of reproductive age. The process of endometriotic implant growth is mediated by many complex interactions of immunologic, hormonal, genetic, and environmental mediators. Vitamin C (ascorbic acid), besides playing a role in preventing invasion and metastasis, is an antioxidant having anti-inflammatory and -angiogenic effects. In this study, we aimed to investigate the effect of vitamin C on the prevention and regression of endometriotic implants in a rat model of endometriosis. MATERIALS AND METHODS This was a prospective, comparative, experimental animal study. After endometriotic implants were induced simultaneously, rats were divided into three groups. Group A was given 500 mg/kg of intravenous vitamin C every 2 days, starting immediately after implantation (n = 11). All rats had a second operation 21 days after the initial one and had the lesion volumes measured. Group B was given 500 mg/kg of intravenous vitamin C every 2 days, starting 21 days after this operation (n = 11). All rats were sacrificed 21 days after the third operation. Implant volume, weight measurements, and histopathological evaluation of the lesions were carried out. Group A received vitamin C throughout the study, while Group C (n = 11) was not given any medication. The findings in the three groups were compared. RESULTS At the second laparotomy after the induction, Group A had the smallest implant volume with a statistically significant difference compared to Group B (p = 0.012). The end-of-study volumes of endometriotic implants of group B were significantly smaller than the first volumes (p < 0.05). CONCLUSION Intravenous vitamin C treatment might have a suppressive effect on the prevention of endometriotic implant induction and regression of endometriotic implant volumes.

Abstract
Hydatid disease is an endemic infection which can affect any organ, mainly the liver and lungs. Peritoneal echinococcosis is usually known to occur secondary to hepatic hydatid cyst rupture into the peritoneal cavity. An isolated cyst in the pelvic cavity is considered as primary only when there are no other hydatid cysts. Herein, we report an isolated pelvic-cervical hydatid cyst which presented without any involvement of the other abdominal organs or lungs. Our patient, a 27-year-old woman with the primary complaints of dyspareunia and chronic pelvic pain, had thin-walled large cystic mass originating from the cervix, diagnosed by ultrasonography. She underwent surgery with the most likely initial diagnosis of exophytic fibroid with cystic degeneration. Gynecologists should be aware of the possibility of isolated primary hydatid cyst of the pelvic cavity and should consider this condition in the differential diagnosis of cystic pelvic masses, especially in areas where the disease is endemic.

Abstract
In this article, we presented a 54-year-old male who was admitted with complaints of nasal obstruction with snoring and mouth breathing for one year. Anterior rhinoscopy revealed a mass arising from the inferior nasal concha on the left side. After computed tomography evaluation, endoscopic examination and incisional biopsy, the mass was removed en bloc endoscopically. The histopathological analysis resulted in a diagnosis of a fungiform papilloma. Fungiform papillomas arise almost exclusively on the nasal septum, while inverted papillomas predominantly affect the lateral nasal wall. To our knowledge, no previous report of fungiform papilloma involving the inferior concha has been published in the English literature.

Abstract
This study examined the frequency of E-cadherin expression in endometrial biopsy or hysterectomy specimens from patients diagnosed with endometrial adenocarcinoma and in normal endometrial tissue specimens. E-cadherin expression was detected by immunohistochemistry using monoclonal antibody to E-cadherin. Specimens were classified as positive when ≥ 5% of the tumour cells showed staining for E-cadherin, irrespective of the pattern of staining. Twenty-three endometrioid carcinomas and nine non-endometrioid (four papillary serous and five clear cell) carcinomas were studied, along with 10 normal endometrial tissue specimens as controls. E-cadherin expression was significantly less frequent in non-endometrioid carcinomas compared with endometrioid carcinomas and controls. There was no statistically significant difference in the frequency of E-cadherin expression between endometrioid carcinomas and controls. In conclusion, this study demonstrated that uterine non-endometrioid (papillary serous and clear cell) carcinomas were less likely to express E-cadherin compared with endometrioid carcinomas and normal endometrial tissue. This may help to explain the more aggressive behaviour of non-endometrioid carcinomas.
