RESUMEN

INTRODUCTION: Pemphigus refers to a group of rare autoimmune vesiculobullous diseases with high morbidity and mortality, mainly affecting the skin and the mucosae. AIM: To evaluate the incidence of pemphigus in the Eastern region of Turkey by analysing the clinical characteristics of the patients including the drugs used in the treatment and their side-effect profiles and dosing schedules, duration of treatment, length of hospital stay, and the characteristics of the lesions. MATERIAL AND METHODS: The retrospective study included 130 pemphigus patients who were admitted to the in- and out-patient dermatology clinics at the University Medical School between January 2005 and October 2017. Age, gender, length of hospital stay, localization of the lesions, initial and maintenance dosages, treatment-related complications, comorbidities, family history, and smoking status were recorded for each patient. RESULTS: The 130 patients included 62 (47.69%) men and 68 (52.31%) women, of which 73 (56.15%) patients had a smoking history. The annual incidence rate of pemphigus was 1.036/100,000 population and pemphigus vulgaris (PV) was the most common clinical subtype of pemphigus in our patients (n = 122; 93.85%). The most common side effect of the treatment was oral candidiasis, followed by Cushingoid appearance. CONCLUSIONS: The results indicated that the incidence of pemphigus is remarkably high in the Eastern region of Turkey and the associated factors including lifestyle changes should be taken into mind when considering these patients.

RESUMEN

INTRODUCTION: Lupus erythematosus (LE) is an autoimmune disease characterized by a broad range of cutaneous manifestations. Discoid LE (DLE) is the most common chronic manifestation of LE. Literature reviews show that there are a limited number of large-series studies investigating DLE. Additionally, there is still no consensus on the etiological factors of DLE such as sun exposure and smoking. AIM: To evaluate the clinical and demographic characteristics of patients with DLE. MATERIAL AND METHODS: The study included patients who were hospitalized in the inpatient and outpatient clinics at the Dermatology Department. Age, gender, treatment method, history of smoking, antinuclear antibody positivity, progression to systemic lupus erythematosus (SLE), photosensitivity, and laboratory findings were recorded for each patient. RESULTS: The study included 132 patients comprising 67 (50.8%) men and 65 (49.2%) women. A family history was found in 3.8%, SLE was detected in 5.3%, and photosensitivity was revealed in 50.0% of the patients. ANA positivity was found in 23.7%, a history of smoking was revealed in 61.4%, and chronic sun exposure was detected in 42.4% of the patients. CONCLUSIONS: Discoid LE, though identified long ago, remains unelucidated and there are very few studies in the literature reporting on DLE. The results indicated that smoking and chronic UV exposure are important risk factors for DLE. Moreover, although ANA positivity was high in our patients, the rate of progression to SLE was remarkably low. The results also showed that, contrary to common belief, there is no female preponderance in DLE.

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

This study aimed to investigate the possible protective effect of paricalcitol on experimental amikacin-induced nephrotoxicity model in rats. Wistar albino rats (n = 32) were allocated into four equal groups of eight each, the control (Group C), paricalcitol (Group P), amikacin-induced nephrotoxicity (Group A), and paricalcitol-treated amikacin-induced nephrotoxicity (Group A + P) groups. Paricalcitol was given intra-peritoneally at a dose of 0.4 µg/kg/d for 5 consecutive days prior to induction of amikacin-induced nephrotoxicity. Intra-peritoneal amikacin (1.2 g/kg) was used to induce nephrotoxicity at day 4. Renal function parameters, oxidative stress biomarkers, oxidative DNA damage (8-hydroxy-2'-deoxyguanosine/deoxyguanosine ratio), kidney histology, and vascular endothelial growth factor (VEGF) immunoexpression were determined. Group A + P had lower mean fractional sodium excretion (p < 0.001) as well as higher creatinine clearance (p = 0.026) than the amikacin group (Group A). Renal tissue malondialdehyde levels (p = 0.035) and serum 8-hydroxy-2'-deoxyguanosine/deoxyguanosine ratio (8-OHdG/dG ratio) (p < 0.001) were significantly lower; superoxide dismutase (p = 0.024) and glutathione peroxidase (p = 0.007) activities of renal tissue were significantly higher in group A + P than in group A. The mean scores of tubular necrosis (p = 0.024), proteinaceous casts (p = 0.038), medullary congestion (p = 0.035), and VEGF immunoexpression (p = 0.018) were also lower in group A + P when compared with group A. This study demonstrates the protective effect of paricalcitol in the prevention of amikacin-induced nephrotoxicity in an experimental model. Furthermore, it is the first study to demonstrate that paricalcitol improves oxidative DNA damage in an experimental acute kidney injury model.

RESUMEN

The term splenosis describes autotransplantation or implantation of ectopic splenic tissue within the abdominal cavity or in any other unusual body compartment. In addition to the diagnostic dilemma it causes, splenosis may also lead to persistence or recurrence of hematologic dysfunctions by its preserved immune activity especially in cases of splenectomy due to hematologic indications. Herein, we present a 40-year-old female who had splenectomy for idiopatic thrombocytopenic purpura, and was identified to have splenic tissue within left lobe of the liver during further assessment of ongoing thrombocytopenia.

RESUMEN

Skin reactions against injected or implanted foreign materials are not rare. Siderosis is a disease characterized by the accumulation of iron in various tissues. Brownish-gray discoloration of the skin can be seen as a side-effect on the injection area after the parenteral iron treatment. Here, we present cutaneous siderosis case developed after multiple intramuscular iron injection on the gluteal region for iron-deficiency anemia. Development of cutaneous siderosis after intramuscular iron injection rarely has been reported in the literature before.

RESUMEN

The risk of infection in burns is well-known. In recent decades, the antimicrobial resistance of bacteria isolated from burn patients has increased. For this reason, a retrospective study was conducted at Van Training and Research Hospital to analyze the bacterial isolates from the wounds of patients admitted to the Burn Unit and to determine the susceptibility patterns of the commonly cultured organisms over a 3-year period, January 2009 to December 2011.A total of 250 microorganisms were isolated from burn wounds of 179 patients. Our results revealed that the most frequent isolate was Acinetobacter baumannii (23.6%), Pseudomonas aeruginosa (12%), Staphylococcus aureus (11.2%), Escherichia coli (10%) respectively. Multidrug-resistance has emerged as an important concern in our burn unit. Tigecycline, and colistin were found to be the most active drugs against Acinetobacter baumannii. Carbapenems and amikacin, were found to be the most active drugs against other gram negative bacteria. Vancomycin and linezolid were active against gram positive bacteria.Aggressive infection control measures should be applied to limit the emergence and spread of multidrug-resistant pathogens.

RESUMEN

Intravascular lymphoma (IVL) is a rare extra nodal subtype (usually of B-cell origin) presenting with infiltration of large neoplastic lymphocytes into lumina of blood vessels, leading to vascular occlusion. The early diagnosis is very crucial, however it is usually diagnosed postmortem investigation in most of the cases. A 56-year-old female presented with elevated creatinine level, and anasarca-type edema that superimposed with hard, indurated, erythematous plaques extending to inguinal region, abdomen, anterior aspect of chest, and face. B-cell IVL was confirmed with skin biopsy. The patient had some degree of clinical improvement following chemotherapy. B-cell IVL presenting with anasarca edema was not previously reported in the literature. Even if its rarity, IVL should be considered in the differential diagnosis of renal failure with anasarca edema.

RESUMEN

In this study, our aim was to determine the possible effects of Helicobacter pylori(HP), chronic atrophic gastritis (CAG), and gastrointestinal metaplasia (GIM) on survival in operated bowel type gastric cancer patients (INT-GC). Among 548 patients, 347(63.3%) were male. The median age was 57 years. Disease-free survival (DFS) and overall survival (OS) were significantly shorter in patients with GIM than those in patients without GIM (log rank, P = 0.003 and log rank P = 0.003, respectively). Multivariate analysis showed that presence of GIM (HR, 2.1) was found to be an independent factor of worse DFS. In our study, stage pIII patients with GIM had significantly shorter DFS and OS than those without GIM (log rank p = 0.008 and log rank p = 0.001, respectively). However, in subgroup analysis of patients with GIM, there was no significant DFS and OS difference between patients with stage pI and pII disease (log rank p = 0.999, log rank p = 0.184 vs. log rank p = 0.409, log rank p = 0.281, respectively).

RESUMEN

Pancreatic neuroendocrine tumors (PNETs) are rare malignancies characterized by insidious onset and mostly present with metastasis at the diagnosis. Lung metastasis manifesting diffuse ground-glass opacity is a very rare pattern that is difficult to distinguish from nonmalignant pulmonary diseases. Recognition of this atypical metastases pattern and avoidance of this potential pitfall are crucial. We report a unique case of the Metastatic Pancreatic Neuroendocrine Tumor Mimicking Interstitial Lung Disease diagnosed by transbronchial lung biopsie. Keywords: Neuroendocrine Tumor, Metastasis, Groundglass opacity, interstitial lung disease.

RESUMEN

INTRODUCTION: The effect of obesity on response to neoadjuvant chemotherapy (NACT) remains unknown. We aimed to investigate the effect of obesity on response to NACT and survival in locally-advanced gastric cancer (GC). METHODS: From 2010 to 2019, 142 GC patients with clinical stage III disease who underwent curative surgery after NACT were enrolled. Patients were divided into 3 groups according to body mass index (BMI) as follows; BMI < 25 kg/m2, BMI = 25-30 kg/m2, and BMI > 30 kg/m2. The Mandard tumor regression grading system was used for tumor regression grade (TRG). RESULTS: Of the 142 GC patients, 45(31.7%) were female. The median age was 58 years. BMI was < 25 kg/m2 in 60 (42.3%) patients, 25-30 kg/m2 in 44 (31%) patients, and > 30kg/m2 in 38 (26.8%) patients. The numbers of patients with TRGI-II, TRGIII, and TRGIV-V were 35 (24.6%), 44 (31%), and 63 (44.4%), respectively. There was no statistically significant difference among BMI groups in terms of disease-free survival (DFS) and overall survival (OS) (p = 0.919 and p = 0.398, respectively). According to TRG groups; mDFS was 46 months in TRG I-II, 28 months in TRG III, and 18 months in TRG IV-V (p <0.001). In multivariate analysis, presence of perineural invasion and lymphovascular invasion were the factors affecting TRG. CONCLUSION: In our study, we found that pre-treatment obesity did not affect the TRG in clinical stage III GC patients. However, a better TRG status was associated with improved survival.

RESUMEN

OBJECTIVES: To investigate the expression of laminin receptor 1 (LR1), a non-integrin-type laminin receptor, in gestational trophoblastic diseases and normal first-trimester placenta, since it may play a role in controlling trophoblast invasion in normal and molar pregnancies. METHODS: Paraffin sections from 24 gestational age controlled normal first-trimester placentas, 47 partial moles, 56 complete moles, 3 invasive moles, 4 gestational choriocarcinomas, and 1 placental-site trophoblastic tumor were studied immunohistochemically for expression of LR1. RESULTS: In complete and partial moles, decidual cells showed significantly stronger LR1 protein staining compared to the normal placenta (p<0.01). When compared to the partial moles, weak staining in less than 33% of decidual cells was also more prominent in the normal placenta (p<0.05). Complete and partial moles, invasive moles, choriocarcinomas, and placental-site tumors did not differ from each other with respect to staining intensity. Strong immunostaining for LR1 in decidual cells, cytotrophoblasts, syncytiotrophoblasts, and extracellular matrix cells of partial and complete moles was not significantly correlated with the development of persistent postmolar gestational trophoblastic tumors. CONCLUSIONS: LR1 may be important in the pathogenesis of gestational trophoblastic diseases. The increased expression of LR1 in decidual cells of partial and complete moles may not influence the development of persistent gestational trophoblastic tumor. Since they are seen rarely, multicentric studies should be planned to study LR1 expression in invasive moles and gestational trophoblastic neoplasms.

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

Sarcoidosis is a chronic, multisystem inflammatory disorder of unknown etiology that is characterized by noncaseating granulomas. Although lung involvement is common in sarcoidosis, pleural involvement is rare. Pleural involvement may manifest as a pleural effusion, pneumothorax, pleural thickening and nodules, hydropneumothorax, hemothorax, or chylothorax. Here, we describe a case of sarcoidosis with pleural nodular thickening.

RESUMEN

Endobronchial plasmacytoma is a rare manifestation of extramedullary plasmacytoma. A 49-year-old woman with a history of multiple myeloma consulted to our pulmonary service with progressive dyspnoea and cough and abnormal chest X-ray. A lesion measuring 6 × 5 cm in size existed in anterior baseline of the right lung's lower lobe in thoracic computed tomography in addition to right bronchial narrowing and atelectasis distal in lesions. Diagnostic bronchoscopy was performed previously for the obstruction and biopsy was taken from the lesion in the right middle lobe bronchus. Endobronchial biopsies showed extensive tumour infiltration with plasmocytoid cells. Immunohistochemistry was positive CD138 and Lamda. Microscopic and immunohistochemical findings supported the diagnosis of extramedullary endobronchial plasmacytoma.

RESUMEN

Actinomycosis is a rare, chronic, suppurative and granulomatous disease caused by Actinomyces israelii, which is a filamentous, anaerobic, gram-positive, saprophytic organism in the oral cavity. Diagnosis of actinomycosis depends on positive culture or identification of Actinomyces colonies and sulfur granules in histological specimens. In our case, a mass had been growing in the mandible for eight months. The mass appeared to be malignant, both clinically and radiologically. A histopathological examination of the mandible revealed actinomycosis. It should be noted that actinomycosis can mimic a malignancy, and for differential diagnosis, bone biopsy or fine-needle aspiration should be performed pre-operatively.

RESUMEN

Cyclooxygenase-2 (COX-2) is overexpressed in various types of human malignancies, including squamous cell carcinomas of the esophagus, but its clinicopathologic role in esophageal squamous cell carcinoma (ESCC) remains unclear. The aim of this study was to analyze expression of COX-2 in ESCC and to correlate this expression with clinicopathologic parameters and survival. From 1999 to 2003, endoscopic tissue samples from 110 patients with ESCC were collected for analysis. COX-2 expression was examined through immunohistochemical staining. Clinicopathologic data were analyzed to verify significance. COX-2 expression was detected in 50 of 110 ESCC specimens (45%). COX-2 expression was negative to weak in 73% (COX-2 low) and moderate to strong in 27% (COX-2 high) of tumors. Statistical differences between COX-2 high and COX-2 low were found according to status of the stage (stage IVM1a/IVM1b) (P=.001): cancer antigen (CA) 19-9 (normal/high) (P%.011), CA 12-5 (normal/high) (P=.011), and CA 15-3 (normal/high) (P=.035). Survival was significantly reduced among patients with high COX-2 expression (median overall survival, 3 mo) when compared with the COX-2 low group (median overall survival, 6 mo) (P=.0001). In the univariate analysis, age, body mass index, stage, COX-2, lactate dehydrogenase, CA 12-5, and CA 15-3 were significant factors for survival. With the use of COX regression analysis, only stage (P=.000), COX-2 (P=.000), lactate dehydrogenase (P=.023), and CA 15-3 (P=.002) were independent prognostic factors. Results showed that in patients with ESCC, COX-2 overexpression was significantly correlated with visceral metastases IVM1b). COX-2 overexpression is an unfavorable prognostic factor in ESCC.

RESUMEN

Topical oral sprays are frequently used to prevent and manage oropharyngeal inflammation and lesions. This study investigated the histopathologic changes noted in the oral mucosa of mice after topical application of 3 widely prescribed antibacterial products. The 25 animals were divided into 5 groups and treated for 10 days with 2 sprays daily, as follows: group 1-chlorhexidine gluconate 0.12% + benzydamine hydrochloride 0.15%; group 2-benzydamine 0.27 mg/0.18 mL x 30 mL; group 3-chlorhexidine 0.2%; group 4-fusafungine 1%; and group 5 (cohort)-physiologic serum. On day 10 after drug administration, biopsy specimens were taken from the oropharyngeal mucosa of the tongue, the cheek mucosa, and the tongue base; these were examined under a light microscope and were classified as normal or pathologic. All topical oral sprays produced some degree of histopathologic change, such as hyperplasia, fibrosis, low-grade dysplasia, congestion, or edema. The local irritant effects of topical oral sprays should be considered when treatment is selected for patients with oropharyngeal disorder.

RESUMEN

OBJECTIVES: Rhinolithiasis is the presence of mineralized and calcareous formations located in the nasal cavity. They have rare occurrence and can be easily confused with infection or obstruction of upper airways. If they are undetected for a long time, they may grow large enough to cause of nasal obstruction, mimicking sinusitis. Seven cases of rhinolithiasis were presented, and their diagnosis was made by rigid endoscopic nasal examination. Also computerized tomography scan was used to describe the size and site of the rhinoliths accurately. Our purpose was to determine the role of rigid nasal endoscopy in the diagnosis and the treatment of rhinolithiasis. METHODS: In this study, seven cases of rhinolithiasis, who were diagnosed and treated by rigid nasal endoscopy were presented. RESULTS: Between January 2000 and November 2004, seven cases (four males and three females; age ranged from 8 to 45 years) with rhinolithiasis were diagnosed. The most frequent symptoms were nasal obstruction with purulent rhinorhea, nasal and oral malodor. As complementary examinations, computerized tomography and simple X-ray of paranasal sinuses were used to locate and measure the dimension of calcareous mass, and to reveal possible invasion of the adjacent structures. The removal of rhinolithiasis was done with rigid nasal endoscopy under topical anesthesia in six cases and general anesthesia in one case.
