Obturator Hernia: A Rare Case of Acute Mechanical Intestinal Obstruction
Ibrahim Aydin,Ahmet Fikret Yucel,Ahmet Pergel,Dursun Ali Sahin
Case Reports in Surgery , 2013, DOI: 10.1155/2013/256062
Abstract: Obturator hernia is a rare type of pelvic hernia which generally occurs in elderly patients with accompanying diseases. Because it is difficult to diagnose before surgery, the morbidity and mortality rates for obturator hernia are high. The most common symptom is strangulation combined with mechanical intestinal obstruction. 1. Introduction Obturator hernia is a type of pelvic hernia in which a bowel segment protrudes through the obturator foramen adjacent to the obturator vessels and nerve. It occurs more frequently in patients with ascites, chronic constipation, and chronic obstructive pulmonary disease and in thin, elderly multiparous women [1]. The most common clinical symptom is strangulation combined with mechanical intestinal obstruction. Because the symptoms are nonspecific, obturator hernia is difficult to diagnose, and most patients are diagnosed during surgery. Obturator hernias occur frequently in elderly patients with accompanying diseases, and therefore the morbidity and mortality rates are high [2]. Currently, diagnostic imaging, especially computed tomography, is widely used to diagnose obturator hernias before surgery in the early stages of the disease [3]. The aim of this report was to present the case, accompanied by relevant literature, of a patient with mechanical intestinal obstruction who was diagnosed with obturator hernia using computed tomography. 2. Case Report A 76-year-old female patient weighing 42?kg presented to the ER with a four-day history of abdominal pain, abdominal swelling, nausea, vomiting, constipation, and inability to pass gas. Her physical examination revealed abdominal distention and tenderness, and she had hyperactive bowel sounds. No palpable hernia was located. Her lab tests were normal except for elevated white blood cell count (12500/mm3). Direct abdominal X-ray images obtained in a standing position revealed dilated loops in the small intestines and gas fluid levels. Her computed tomography results showed a small intestine loop completely herniated through the obturator foramen and dilatation in the proximal small bowel (Figure 1). The patient was diagnosed with obturator hernia and underwent surgery. During surgery, a strangulated small intestine segment extending through the left obturator foramen was detected (Figure 2). After reduction, the obturator foramen was closed with primary sutures (Figure 3). The patient did not experience any postoperative problems and was discharged on the fifth day after admittance.

Ahmet Pergel,Ahmet Fikret Yucel,A. Serdar Karaca,Ibrahim Aydin,Dursun Ali Sahin,Nilgun Demirbag
Case Reports in Medicine , 2011, DOI: 10.1155/2011/972168
Abstract: Six to eight percent of granular cell tumors are seen in the breast. Although mostly benign, they rarely have malignant features clinically and radiologically reminding of breast cancer. This may lead to a potential misdiagnosis of breast carcinoma and overtreatment of patients. The final diagnosis is made by immunohistochemical examination. We performed excisional biopsy on a patient who was diagnosed to have a breast mass. The histopathological examination of the mass revealed granular cell tumor.
Laparoscopic Cholecystectomy During Abdominoplasty: Case Report
Cukurova Medical Journal , 2013,
Abstract: We aimed to present the phenomenon of laparoscopic cholecystectomy and abdominoplasty which we diagnosed at the same period the abdominal laxation, diastase of rectum and cholelithiasis that we think in the literature the first samples without leaving any trocar entrance mark.A 58 year old female patient has consulted to the polyclinic of plastic surgery due to prolapsus on the abdominal region. Gall bladder multiplestones were ascertained through abdominal ultrasonograpy. On request and to provide minimal cosmetic failure to the patient, cholecystectomy and abdominoplasty is performed at the same session. Patients with abdominal pathologies that may occur after operations requiring surgery such as abdominoplasty very serious impact on cosmetics. Concordantly, we strongly suggest to take abdominal USG, even if there is no additional complaints especially before the plastic surgery operations and abdominoplasty, for ascertain the existent patologies.

Testosterone- and Cortisol-Secreting Adrenocortical Oncocytoma: An Unusual Cause of Hirsutism
Serap Baydur Sahin,Ahmet Fikret Yucel,Recep Bedir,Sabri Ogullar,Teslime Ayaz,Ekrem Algun
Case Reports in Endocrinology , 2014, DOI: 10.1155/2014/206890
Abstract: Objective. Oncocytomas of the adrenal cortex are usually benign and nonfunctional. They are rarely seen as the cause of hirsutism. Therefore, we aimed to report a case of adrenocortical oncocytoma presenting with hirsutism. Methods. We report a testosterone- and cortisol-secreting adrenal oncocytoma in a 23-year-old female patient presenting with hirsutism. Results. The patient had the complaint of hirsutism for the last year. Laboratory tests revealed total testosterone level of 4.2?ng/mL, free testosterone of >100?pg/mL, and DHEAS level of 574?μg/dL. There was no suppression in cortisol levels with 2?mg dexamethasone suppression test (5.4?μg/dL). Adrenal MRI revealed a ?mm isointense solid mass lesion in the left adrenal gland and the patient underwent laparoscopic left adrenalectomy. Pathological examination confirmed the diagnosis of benign adrenocortical oncoyctoma. Conclusion. This well-characterized case describes a testosterone- and cortisol-secreting adrenocortical oncocytoma as a possible cause of hirsutism. To our knowledge, this is the second report in the literature. Adrenal oncocytomas should always be considered in the differential diagnosis of hirsutism. 1. Introduction Hirsutism, defined as excessive male-pattern hair growth, affects between 5 and 10% of women of reproductive age and most women with hirsutism have polycystic ovary syndrome [1, 2]. Androgen-secreting tumors are rarely seen as the cause of hirsutism. In an epidemiological study, the frequency of androgen-secreting tumors was 0.2% in 950 hirsute women [3]. Most testosterone-secreting tumors arise from the ovary and rarely origins from the adrenal gland. Oncocytic neoplasms or oncocytomas usually arise in the kidneys or thyroid, parathyroid, salivary, or pituitary glands [4]. Oncocytomas of the adrenal cortex are extremely rare and usually detected incidentally [5]. Adrenal oncocytomas are usually benign and nonfunctional in most of cases. Herein, we report a testosterone- and cortisol-secreting adrenal oncocytoma in a 23-year-old female patient presenting with hirsutism. 2. Case Report A 23-year-old female patient admitted to endocrinology outpatient clinic with the complaint of hirsutism for the last year. Excessive hair growth was identified to originate from facial and mandibular areas initially and then to spread to abdominal and thoracic regions. She had regular menstrual cycles since her first period by the age of 12. Medical background and family history were unremarkable. Physical examination revealed that body temperature was 37°C, pulse rate was 80 beats/min,

Abstract: The existance of hazardious materials including biological, chemical, and physical agents such as carbon dioxide, carbon monoxide, sulphur dioxide, nitrogen oxides, radon, volotile organic compounds, microorganisms in houses and the other non-industrilized buildings have been defined as indoor air pollution . Indoor air pollutants could possible arised from inside or outside environment and categorized into six subgroups. Almost 80% Turkish population have living in the urban areas and people in the cities have spending approximetely 90% of their time in the closed enviroments, health problems could increased due to indoor air pollution. Moreover, currently there is no specific regulation on this area. [TAF Prev Med Bull. 2007; 6(3): 221-226]

Journal of Experimental and Integrative Medicine , 2012,
Abstract: Objective: Nitric oxide (NO) is produced by various cells in response to mitogenic and inflammatory stimuli. This molecule plays important roles in the transmission of cellular signals, and in defense against pathogens by oxidative toxicity. In biological fluids, NO is rapidly converted to nitrite and nitrate. Therefore, the best index of total NO production is the sum of nitrite and nitrate. The most widely accepted classical method for measuring NO is the Griess method. Widely used commercial colorimetric kits involving the Griess method are very costly. In this study, we aimed to compare two different applications of Griess method for NO measurement. Methods: We tested two identical sets of 155 human plasma samples for NO with two different applications of the Griess method. These applications involved different deproteinization and nitrate-nitrite conversion methods. The first application was a commercial (Cayman Chemical) NO colorimetric assay with deproteinization via ultrafiltration and nitrate-nitrite conversion using NADPH-dependent nitrate reductase, and the second one was an in-house application involving sulphanilamide and N-(1-naphthyl) ethylendiamine dihydrochloride compounds with NaOH and ZnSO4 deproteinization and VaCl3 was used for nitrate-nitrite conversion. Results: The results with the se two different Griess applications were statistically correlated (r=0.954, p<0.001). The in-house method gave higher NO levels due to possible matrix-related interference; however, a regression formula was derived to convert the results of the in-house method (x) to that of commercial colorimetric assay (y): y = 1.38 + 0.388x. Conclusion: The cost of the in-house Griess method used in this study was almost one-third of the commercial assay. Use of this in-house method and the accompanying regression formula is a highly accurate and economical method for measuring NO with the Griess method. [J Exp Integr Med 2012; 2(2.000): 167-171]

Abstract: The aim of this study was to determine the relationship between socioeconomic variables and coronary hearth disease (CHD) and risk factors among a Turkish urban population aged 20 years and older. Hypertension, waist circumferences, total cholesterol, high density lipoprotein cholesterol, glucose intolerance, and smoking were used as the major CHD risk factors. CHD was defined as the previous doctor diagnosis and derivation ECG findings. The study completed with 607 people, of those 389 were women. Among women, illiterates showed significantly higher CHD, hypertension, central obesity, and glucose intolerance were higher than the higher educated groups. Additionally hypertension, central obesity and high cholesterol were higher among the women with agricultural origin. Hypertension was higher in the less educated men. Of those economical status was less favorable compared with the current status glucose intolerance prevalence was higher. As the conlusion socioeconomic and CHD and CHD risk factors were inversy associated like industrial countries. [TAF Prev Med Bull. 2007; 6(1): 27-40]

Abstract: Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total and specific IgE, IgG, IgM, IgA and complement. Total and specific IgE were determined by ELISA. Specific IgG levels were measured by indirect hemaglutination.Total IgG, IgM, IgA and complement (C3 and C4) were detected by nephelometry. Imaging studies were also carried out during the follow-up. In none of the patients hydatid cysts were detected during the follow-up. Total IgE levels in the sera of the patients decreased to normal six months after surgery. Although specific IgE against echinococcal antigens decreased one year after operation, levels were still significantly high. There were no changes in the levels of anti-Echinococcus IgG and total IgG in follow-up period. Additionally, other parameters, such as IgA, IgM, C3 and C4, were not affected.

Abstract: Inflammatory myofibroblastic tumor is composed of myofibroblast and inflammatory cell infiltration of the tissue. Malign transformation and recurrence rate of this tumor is rare and accepted as benign fibroinflammatory disease. The main etiology is unclear, but infection, trauma, and immunologic event are accused. In this study, we presented a 75-year-old man with a mass on his tongue, which was diagnosed as “inflammatory myofibroblastic tumor.” This type of tumor is rarely seen in the tongue and might be difficult to diagnose. Complete mass excision was provided for an adaquete treatment. 1. Introduction Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor [1]. The etiology of IMT is contentious, also the nature of this tumor type (benign or malign) is still controversial [1–3]. But, because of its rarity, the current conception is altered from a benign reactive process to an intermediate neoplasm [4]. Different terms such as; inflammatory pseudotumor, histiocytoma, plasma cell histiocytoma complex, plasma cell granuloma, fibrohistiocytoma, xanthomatous granuloma, myxoid hamartoma, xanthomatous pseudotumor, spindle cell pseudotumor, inflammatory fibrosarcoma, benign myofibroblastoma, and inflammatory myofibroblastic proliferation were used for defining this tumor. World Health Organization (WHO) had consolidated this term as IMT in 1994 and declared it as a diagnostic classification for intermediate soft-tissue myofibroblastic neoplasm according to its well reproducible histological morphology [4, 5]. The tumor reported in the lung originally, but extra-pulmonary form, has been described in different organs and anatomic sites [6, 7]. Regardless of the site of origin, it is a circumscribed mass-forming process, composed of myofibroblasts, fibroblasts, histiocytes, and plasma cells. Although stromal fibrosis is a finding that is usually seen, tumor tends to be limited in the focal area [6, 8]. IMT is preferentially occurring in children and young adults [6]. In this report, we presented a 75-year-old male patient with inflammatory myofibroblastic tumor of the tongue presenting with pediculated large mass. 2. ??Case Report A 75-year-old man was referred to our clinic with a painless, pediculated large mass on the left side of the tongue. The lesion grew rapidly within four months. Oral examination revealed an approximately 4 centimeter (cm) in diameter, hard, partially ulcerated, and pediculated large mass on the left side of the tongue (Figure 1). There was no regional lymphadenopathy, and the remainder of physical examination was
