RESUMEN

Laminin receptor 1 (LAMR) may have a role in the progression of premalignant squamous epithelial lesions to cervical cancer. Therefore, we aimed to investigate the expression of laminin receptor 1 (LAMR) in normal, premalignant, and malignant tissues of the uterine cervix. Paraffin blocks of 129 specimens with the diagnoses of normal cervical tissue (n = 33), cervical intraepithelial neoplasia (CIN) 1 (n = 30), CIN 2 (n = 14), CIN 3 (n = 28), and squamous cell carcinoma (n = 24) were immunohistochemically stained with LAMR antibody and its expression percentage, pattern, and intensity in these tissues were assessed. Compared to the other groups, the nonstaining with LAMR was highest in low grade squamous intraepithelial lesion (LSIL) (p < 0.0001). LAMR expression, which was positive in less than 50% of cells with weak staining, increased significantly between normal cervical epithelium and high-grade squamous intraepithelial lesion (HSIL) or invasive carcinoma, as well as between LSIL and HSIL (p < 0.0001). Between LSIL and invasive carcinoma, a significant increment was also observed for weak staining in less than 50% of cells (p < 0.001). LAMR expression, which was positive in more than 50% of cells with strong staining, was significantly higher in normal cervical tissue compared to the other groups (p < 0.0001). Disease progression related gradual increment of LAMR expression from normal cervical epithelium or LSIL towards HSIL or cervical cancer reveals that LAMR may play an important role in the transition from premalignant to malignant state in cervical lesions.

RESUMEN

The objective of present study was to examine endometrial tissue Be, As, Cr, Mo, Sr, Ti, Tl, Cu, Co, Se, Zn, Mn, Fe, Cd, Pb, Mg, P, erythrocytes CAT, SOD, GSH-Px, GSH, MDA, serum retinol, cholecalciferol, phylloquinone, TSA, LSA, TOS, and TAS status and to evaluate the relationships between the variables. The study had 110 participants; of these, 50 were women with uterine myoma (UM), 10 were women with endometrial cancer (EC), and 50 were healthy female subjects. In the study, vitamin analyses by HPLC and element analyses were determined using ICP-OES method. It was observed that EC group was significantly lower than healthy group in terms of levels of cholecalciferol (p < 0.05), phylloquinone (p < 0.01), GSH (p < 0.05), Fe (p < 0.05), and had a significant rise in Mg/Fe (p < 0.01) and Zn/Fe (p < 0.05) in preoperative period. UM group had significantly lower retinol (p < 0.05), phylloquinone (p < 0.001), GSH-Px (p < 0.01), GSH (p < 0.01), Cr (p < 0.01), Cu (p < 0.05), Mg (p < 0.01), and Zn (p < 0.01) levels than control group in preoperative period and significantly higher levels of MDA (p < 0.01), TSA (p < 0.01), and LSA (p < 0.01) than control group. It was found that significant associations were observed between Cu-CA 15-3 (r = 0.558, p = 0.016), Mn-CA 15-3 (r = 0.511, p = 0.030), P-CA 15-3(r = - 0.502, p = 0.034) and with UM, also between GSH-CA-125 (r = - 0.825, p = 0.022) and with EC group. The results of correlation analysis observed that concentrations of Cu, Mn, P, and GSH together with CA 15-3 and CA-125 levels might be important for monitoring patients with UM and EC before surgery.

RESUMEN

Clinical relevance: Since acne vulgaris is a disease of the sebaceous glands, it may have potential effects on the ocular surface and tear homoeostasis, which are essential for good vision. Optometrists should be aware of ocular surface pathologies when prescribing glasses or contact lenses for the visual rehabilitation of these young patients.Background: To evaluate the ocular surface features, meibomian glands, and tear parameters of patients with acne vulgaris.Methods: The right eyes of 70 individuals (34 patients with acne vulgaris, 36 healthy volunteers) were evaluated. The tear break-up time of participants was measured, and the Schirmer test was performed. Then, to determine ocular surface characteristics, samples were taken from the conjunctiva for impression cytology. Finally, the loss rates of the upper and lower eyelid meibomian glands were determined by taking meibography (Sirius, CSO, Florence, Italy).Results: Tear break-up time was significantly lower in the study group compared to the control group (p < 0.001). No statistically significant difference was determined between the groups in respect of Nelson grade in the conjunctival impression cytology (p = 0.141). Grade 3 cytological changes were not observed in either group. The median value of the loss rate in the meibomian glands in the upper eyelid of patients with acne vulgaris was 19.10% (IQR: 18%), while it was 8.75% (IQR: 9.53%) in the control group (p = 0.001). The median value of the loss rate in the meibomian glands in the lower eyelid was 15.70% (IQR: 15.13%) and 7.70% (IQR: 6.53%) in the acne vulgaris and control groups, respectively (p < 0.001).Conclusion: Our study shows that patients with acne vulgaris may have a predisposition to meibomian gland damage and tear instability. Therefore, we consider that a more detailed ophthalmologic examination should be performed in patients with acne vulgaris.

RESUMEN

OBJECTIVE: The prognosis of breast cancer (BC) is determined directly based on the stage of disease at the time of diagnosis. Proliferative breast lesions (PBLs) are an important risk factor for BC development. The risk of developing BC varies according to the presence of extent of proliferation in the breast lesions. We aimed to investigate the effect of BC risk factors on the PBLs in this study. MATERIALS AND METHODS: Patients who visited the surgical clinic of the university during the past 6 years who presented with PBLs with or without atypia by fine/core needle aspiration biopsy were included in this study. The relationship between PBLs and BC risk factors such as the age, mass size, Body Mass index (BMI), smoking, sports activity, BC family history, the use of hormone replacement therapy, number of pregnancies, and the duration of breastfeeding were compared. RESULTS: A total of 74 (96.1%) of all patients were women and three were men. The median age of the patients was 38 (range: 19-74) years; the cut-off value of age was 35.5 years. The mean age of patients with PBL-with atypia (PBL-WA) was higher (p=0.005) in the malignant group based on the final pathology and radiological imaging features (for both, p<0.001). The mean size of the mass was large at 2.53±1.33 (1-6) cm; and the cut-off value of the tumor size was 2.5 cm. The mean size was greater in the PBL-WA patients (p=0.171) in the malignant group based on the final pathology and radiological characteristic (respectively, p=0.004 and p=0.016). The mean BMI was 26.8±4.4 kg/m2 (18.8-35.1) and the cut-off value was 25.4 kg/m2. BMI was greater in the PBL-WA group and in the malignant group based on the final pathology (respectively, p=0.002 and p=0.001). Smoking was positive in 66.2% (n=51) of the patients, and it was high in the PBL-WA patients (p=0.001). The percentage of patients with no sports activity was 63.6% (n=49), while it was 20.8% (n=16) for those with once a week sports activity and 15.6% (n=12) for those with twice a week activity. There was family history of BC in 16.9% (n=13) of all patients. The number of positive cases of family history of BC was greater in the malignant group (p=0.001). Hormone replacement therapy was recorded in 11.7% (n=9) of the patients. The mean numbers of pregnancies (2.1±2.4) and breastfeeding duration (32.5±37.4 months) were low in the benign groups due to the relatively lower average age of the patients. CONCLUSION: Based on our analysis, age is an extremely important aspect for assessing PBLs. The age of the patient was statistically significantly greater in the patients with malignant lesions in all groups. The factors lesion size, BMI, smoking habit, and BC family history were also more frequent in the malignant groups. The rate of sports activity was lower in the malignant groups. Thus, it is necessary to evaluate patients individually when evaluating PBLs. It is recommended to evaluate PBLs together with BC risk factors for the better understanding.

RESUMEN

PURPOSE: To evaluate the tear parameters, meibomian glands and lid margin and tarsal conjunctival impression cytology in patients with conjunctivochalasis (CCH). METHODS: The study included 57 patients diagnosed with CCH and 35 healthy volunteers. Tear break-up time (TBUT) was measured and Schirmer test was performed. Meibomian gland morphologies, dropout rates, and meiboscores were evaluated using meibography. Finally, impression cytology samples were taken by pressing the impression filters on the lower lid margin and lower tarsal conjunctiva. The samples were evaluated according to the Nelson grading system. RESULTS: Schirmer test was longer and TBUT was shorter in the study group (p = 0.035 and p < 0.001, respectively). The median of meibomian gland dropout rate was 33.45% (Interquartile range [IQR]; 23.17%-49.75%) and 18.80% (IQR; 12.35%-26.50%) in the study and control groups, respectively (p < 0.001). There was no significant difference in terms of lid-margin cytology between the two groups (p = 0.481). In tarsal conjunctiva cytology, the median value of Nelson grade of the study group was 2 (IQR; 1-2) and that of the control group was 1 (IQR; 1-2) (p = 0.040). When Nelson grade-2 and above was accepted as the pathological limit, it was found that 27.5% of the study group and 15.2% of the control group showed pathological findings (p = 0.204). CONCLUSIONS: In patients with CCH, damage occurs in the tarsal conjunctiva with the effects of redundant conjunctival folds. In these patients, atrophy occurs in the meibomian glands and tear stability is impaired. Therefore, CCH should not be overlooked in clinical practice.

RESUMEN

OBJECTIVE: Paracetamol is thought that it acts by inhibiting the central cyclooxygenase (COX) enzyme; its mechanism of action is still not fully explained. Although its most important side effect is hepatoxicity, it is thought to cause toxicity on the brain in recent years. The present study aims to investigate the treatment and toxic effects of low and high doses of paracetamol on the liver and brain. METHODS: Wistar-albino rats were used in this study. At doses of 20-500 mg/kg, paracetamol was administered intraperitoneally once a day for one and three days. The brain and liver were used for immunohistochemical evaluation using COX-3, prostaglandin E2 (PGE2) and caspase 3 antibodies and for total antioxidant (TAS), total oxidant (TOS) and oxidative stress index (OSI) measurements. Results were evaluated using the Kruskal Wallis test (SPSS ver.24). RESULTS: The liver COX-3 levels were significantly lower in both groups with higher doses (p<0.05). In the brain, there was no statistically significant difference in COX-3 levels between the groups. There was no statistically significant difference in PGE2 levels in the liver and brain between the groups (p>0.05). The caspase 3 level in the liver was statistically significantly higher in the low dose group compared to the other groups (p<0.05). In both liver and brain, OSI values were significantly higher in the 3-day high-dose group compared to others (p<0.05). There was no statistically significant difference between the groups in ALT and AST values (p>0.05). CONCLUSION: The results of our study show that paracetamol inhibits the COX-3 enzyme in the liver but has no effect in the brain, and COX-3 does not have an effect on PGE2. Paracetamol causes apoptosis in the liver only in low doses; higher doses may cause toxicity by increasing oxidative stress, especially in the brain.

RESUMEN

PURPOSE: To evaluate the effect of obstructive sleep apnea-hypopnea syndrome (OSAHS) on the meibomian glands, ocular surface, and tear parameters. METHODS: The study included 59 individuals (32 subjects with OSAHS, 27 control subjects) who underwent polysomnography in the Chest Diseases Clinic. The right eyes of all individuals were evaluated in the Ophthalmology Clinic. The first noninvasive tear break-up time (f-NTBUT) and the average noninvasive tear break-up time were measured, and Schirmer test was applied. Meibography was taken (Sirius; CSO, Florence, Italy), and meiboscore was used for indexing meibography. Finally, a sample was taken for conjunctival impression cytology. RESULTS: In the study and control groups, the median of f-NTBUT was 2.1 seconds [interquartile range (IQR); 1.5-5.0] and 5.7 seconds (IQR; 2.9-8.8) and the median of average noninvasive tear break-up time was 5.6 seconds (IQR; 3.6-9.5) and 7.2 seconds (IQR; 4.2-10.7), respectively (P = 0.007 and P = 0.487, respectively). The mean Schirmer value was 16.3 ± 5.9 mm (range; 5-25) and 17.3 ± 6.6 mm (range; 5-30) in the study and control groups (P = 0.604). In upper eyelid meibography, the median of loss in the meibomian glands was 20.10% (IQR; 11.60%-40.80%) in the study group and 14.70% (IQR; 10.40%-21.30%) in the control group (P = 0.043). In lower eyelid meibography, the median of loss in the meibomian glands was 19.00% (IQR; 13.60%-35.30%) in the study group and 12.40% (IQR; 9.10%-16.40%) in the control group (P = 0.002). The median of the Nelson grade in conjunctival impression cytology was 1 (IQR; 0-1) in the study group and 1 (IQR; 0-1) in the control group (P = 0.445). CONCLUSIONS: The loss in the meibomian glands together with the shortened f-NTBUT shows that there could be a predisposition in OSAHS for evaporative dry eye originating from meibomian gland damage.

RESUMEN

The aim of the present study was to present a case with secondary hydatid cysts in both uterus and colon. The patient was a 71-year-old female living in Hakkari, Turkey. She was admitted to the Van Yuzuncu Yil University Faculty of Medicine Medical Center with complaints of chronic abdominal and pelvic pain, and swelling in the abdomen. First, the sagittal T2 weighted magnetic rezonance imaging (MR) showed a type-3 cyst hydatid with daughter vesicles located at the posterior of uterus. Later, MR revealed a type-2 cystic lesion with detached membrane adhered to the anterior wall of colon and it was reported to be associated with abdomen. When the previous liver surgery history of the patient was kept in mind, the new finding was suggestive of a secondary cystic hydatid . In conclusion, it is possible to diagnose secondary cystic echinococcosis in patients with a history of primary cyst surgery in liver or any other organ by combining the symptoms and imaging findings.

RESUMEN

The Ewing's sarcoma family of tumors (ESFT) incorporates both the wellrecognized primary bone and the extraskeletal soft tissue sarcomas. Primitive neuroectodermal tumors (PNET) and ESFT have a similar neural phenotype and can be considered in the same entity. Here, we will present 28 years old patient with Ewing Sarcoma. Patient was admited chest pain. Chest radiograph showed a suspicious lesion in the left paracardiac area. Computed tomography (CT) scan and positron emission tomography (PET)/CT result were compatible with malignant tumor. The patient was underwent surgical resection as the bronchoscopic result couldn't a malignant finding and pathological finding was detected as Ewing's sarcoma. Ewing's sarcoma should be considered in patients who are very fast growing in the lungs, are properly confined and suspected of malignancy in FDG-PET/CT.

RESUMEN

BACKGROUND: Lichen planus (LP) is an inflammatory disease that affects skin, hair follicles, mucous membranes, and nails. Ki-67 is an antigen associated with the proliferation of cells in all stages of cell cycle except G0. Bcl-2 is a protooncogene that protects cells from apoptosis. COX-2 is an antiapoptotic protein that increases in inflammation. The infiltration of T cells in LP seems to be responsible in the apoptosis of the basal keratinocytes. OBJECTIVE: The purpose of this study was to investigate the effects of prednisolone and acitretin treatments on Ki-67, Bcl-2, and COX-2 expression and apoptosis in patients with LP and the role of Ki-67, Bcl-2, and COX-2 proteins in LP. METHODS: Fifty-eight patients with clinically and histopathologically diagnosed LP who had not been treated with systemic treatment before and 15 healthy volunteers were evaluated prospectively. Pretreatment and posttreatment biopsies were immunohistochemically stained with Ki-67, Bcl-2, and COX-2. The percentage of the stained cells were calculated and recorded. RESULTS: Although the percentage of staining with Ki-67 and Bcl-2 after treatment with prednisolone and acitretin decreased significantly (P < 0.05) in both groups, there was no significant difference between groups (P > 0.05). COX-2 decreased but was not statistically significant. CONCLUSIONS: With this study in cutaneous lichen planus, prednisolone and acitretin treatments reduced Bcl-2 and Ki-67 levels and did not effect COX-2 levels. It should be clarified whether these results can be obtained with any treatment effective in cutaneous lichen planus.

RESUMEN

The patient presented in this study had a form of chronic sclerosing osteomyelitis (CSO) that is rarely reported in calvarial bones and has never been reported in the frontal bone in the literature. We aimed to contribute to the literature with this case study. In this study, we report a 14-year-old girl who presented with swelling and pain in the frontal bone and underwent treatment due to CSO. The patient had no history of trauma and chronic infection. We conclude that CSO should be considered in the differential diagnosis of the patients presenting with cranial swelling whose diagnosis cannot be established based on the radiological findings.

RESUMEN

This study investigated the effects of thymoquinone, silymarin, and N-acetylcysteine in a rat model with carbon tetrachloride (CCl4)-induced hepatotoxicity. Although numerous similar studies are available, we aimed to compare the efficacy of these agents by considering N-acetylcysteine as a reference compound. A total of 50 male Wistar albino rats were randomly designated as 5 groups: Group I, CCl4; group II, thymoquinone and CCl4; group III, silymarin and CCl4; group IV, N-acetylcysteine and CCl4; group V, control group. CCl4 was administered intraperitoneally at a dose of 1.5 mL/kg (a mixture of CCl4: olive oil, 1:2) twice a week. Thymoquinone was administered at a dose of 10 mg/kg, silymarin was administered at a dose of 100 mg/kg, and N-acetylcysteine was administered at a dose of 100 mg/kg by daily intraperitoneal injection. At the end of four weeks, blood and liver tests were analyzed. The results were evaluated statistically via the one-way ANOVA test. A p-value <0.05 was considered statistically significant. Thymoquinone, silymarin, and N-acetylcysteine improved the levels of alanine aminotransferase, tumor necrosis factor-α, platelet-derived growth factor-BB, and interleukin-6, which were increased by CCl4. Thymoquinone and silymarin showed the positive increase in liver glutathione levels. Thymoquinone, silymarin, and N-acetylcysteine improved blood total oxidant status. In the histological examinations of liver tissue, thymoquinone decreased necrosis, and inflammation. The most positive decrease in the α-smooth muscle actin-stained hepatic stellate cell count was only observed with thymoquinone. These findings suggest that thymoquinone, silymarin, and N-acetylcysteine have potential for the treatment of diseases causing liver injury. Among these agents, thymoquinone showed the best results on most of the parameters. Since TQ appears to be at least as effective as SM and NAC in our in-vitro study, we propose that it is time for clinical studies with thymoquinone on hepatotoxicity.

RESUMEN

BACKGROUND: Although antimicrobial efficacy of photodynamic therapy has been studied several times, there is no study investigating its efficacy on pericoronitis. This study aimed to determine whether antimicrobial photodynamic therapy combined with antibiotic therapy is clinically and histologically superior to antibiotic therapy alone in pericoronitis treatment. METHODS: Patients (n = 40) with pericoronitis were divided into two groups (20 patients for each) to receive either antibiotic + indocyanine green + 810 nm wavelength diode laser (antimicrobial photodynamic therapy group) or antibiotic alone. Initial biopsy samples were obtained from the affected tissue of the patients at their first presentation to the clinic before any intervention. The second biopsy samples were obtained on the 3rd day of treatment in both groups from the tissue part not biopsied before; tooth extraction was then performed. All tissue samples were histologically examined to assess inflammatory cell response. Patients' pain (using Visual Analogue Scale) and lymphadenopathy (presence or absence) were clinically evaluated in the first 3 days and on the 7th day of treatment. RESULTS: In the antimicrobial photodynamic therapy group, 100% improvement was achieved regarding pain and lymphadenopathy at the end of the 7th day. Comparison of the inflammatory cell scores of the 2nd biopsy samples between the antibiotic alone and antimicrobial photodynamic therapy groups revealed a significant difference in favor of antimicrobial photodynamic therapy group. CONCLUSIONS: Antimicrobial photodynamic therapy combined with antibiotic therapy for pericoronitis treatment was found to be more successful as compared with the antibiotic therapy alone regarding clinical and histological outcomes.

RESUMEN

BACKGROUND: The purpose of this study was to compare the effects of oral enalapril, an angiotensin-converting enzyme inhibitor (ACE-I), oral candesartan, an angiotensin receptor blocker (ARB), and intralesional corticosteroid treatments in reducing scar formation. METHODS: Twenty male rabbits were divided into five study groups: A (sham), B (control), C (ACE-I), D (ARB) and E (intralesional corticosteroid). The rabbit ear hypertrophic scar model was used. The hypertrophic scars were photographed and analyzed with the program ImageJ quantitatively to determine the degree of collagen fibers. The scar elevation index (SEI) was calculated at the end of the 40th day. Tissue samples were stained with hematoxylin and eosin and Masson's trichrome and examined under light microscopy for the determination of fibroblast number, epithelization, vascularization, inflammation and fibrosis. RESULTS: The SEI was the highest in the control group with the highest number of fibroblasts under the epithelium. In the steroid group, the SEI was significantly lower than both the ACE-I (p: 0.02) and ARB (p: 0.001) groups. The density of type 1 collagen fibers was the lowest in the control group, whereas type 3 collagen fibers were highest in that group. The ACE-I and ARB groups were similar regarding densities of type 1 and type 3 collagen fibers. The density of type 1 collagen fibers was the highest in the steroid group, whereas the density of type 3 collagen fibers was the lowest in that group. CONCLUSIONS: Enalapril, candesartan and intralesional steroid therapies were all effective in reducing scar tissue development; however, enalapril and steroid groups revealed better results.

RESUMEN

We investigated the effects of Leontice leontopetalum and Bongardia chrysogonum on apoptosis, gamma-aminobutyric acid (GABAA) receptor positive cell number, cyclin-B1 and bcl-2 levels and oxidative stress in pentylenetetrazol (PTZ) kindling in rats. Kindling was produced by subconvulsant doses of PTZ treatments in rats. Wistar albino rats were divided into 4 groups; Control, PTZ treated (PTZ), PTZ+L. leontopetalum extract treated (PTZ+LLE) and PTZ+B. chrysogonum extract treated (PTZ+BCE) groups. Extracts were given a dose (200 mg/kg) 2h before each PTZ injection. PTZ treatment significantly decreased the glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activities and bcl-2 levels and increased the total oxidant status (TOS), malondialdehyde (MDA), cyclin B1, oxidative stress index (OSI) and number of neurons that expressed GABAA receptors when compared to the control. LLE and BCE possessed antioxidant activity in the brain and ameliorated PTZ induced oxidative stress, decreased cyclin-B1, increased bcl-2 levels, and kept the GABAA receptor number similar to that of the control despite the PTZ application.

RESUMEN

A solitary fibrous tumour (SFT) is a rare mesenchymal tumour that frequently originates in the mesothelium-covered surfaces, such as the pleura and peritoneum. It may develop in various body parts, including the head and neck. These tumours may arise in several different patterns, which results in difficulties in diagnosing them. This case is a solitary tumour developing from the palatine tonsil in a 17-year-old male patient; it is the second case in the literature. The tumour has the histopathological characteristics of a patternless pattern, a slight pleomorphism, and a composition of hypercellular and hypocellular sites. Immunohistochemically, the tumour cells showed a strong positive staining with CD34, Bcl-2, and vimentin. No recurrence developed in the patient's approximately 18-month-long follow-up period.

RESUMEN

OBJECTIVE: To review lip cancer patients with respect to age, gender, location and histological type of tumour, and risk factors. METHODS: This retrospective study was conducted at the Yuzuncu Yil University, Van, Turkey, and comprised medical records of the histologically confirmed lip cancer patients who presented between 1994 and 2010. No patient had neck nodes or evidence of distant metastasis. RESULTS: Of the 91 patients 73(80.22%) were men and 18(19.78%) were women. The overall mean age was 62.32±13.88 years (range: 25 to 97 years). Histologically, the tumour was a squamous cell carcinoma in 81(89.01%) cases and a basal cell carcinomas in 10(10.99%) cases. Upon admission, the mean diameter of the tumour in squamous cell carcinoma patients was 2.03±1.23 cm and 1.87±1.29 cm in basal cell carcinoma patients. As for the tumour differentiation, 67(84.72%) of the squamous cell carcinoma cases were well differentiated, while 14(17.28%) were moderately differentiated. CONCLUSIONS: The incidence of lip cancer was found to be higher among men, while the histopathological type was mostly squamous cell carcinoma and well differentiated.
