Evaluation of Oropharyngeal Dysphagia in Elderly Patients with Pharyngeal Aberrant Internal Carotid Artery Using the Eating Assessment Tool-10 (EAT-10). Dysphagia 2021; 37:676-682. [PMID: 34226957 DOI: 10.1007/s00455-021-10318-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2020] [Accepted: 05/13/2021] [Indexed: 10/20/2022]
Abstract
Pharyngeal aberrant internal carotid artery (PAICA) has been reported to be a cause of oropharyngeal dysphagia (OD) in case reports. However, as there have been no clinical studies, the relationship between PAICA and OD is not clear. The aim of this study was to investigate the perception of OD in elderly PAICA patients using the Eating Assessment Tool-10 (EAT-10). A study group (Group 1) was formed of patients diagnosed with PAICA from the visualization of a pulsatile mass in the pharynx in flexible fiberoptic endoscopic examination and carotid magnetic resonance angiography tests, and a control group (Group 2) was formed of age-matched healthy volunteers. The study group was subdivided as patients with unilateral PAICA (Group 1a) and patients with bilateral PAICA (Group 1b). The Turkish version of the EAT-10 was applied to all the participants. Total EAT-10 points of ≥ 3 were accepted as abnormal. Normal (< 3) and abnormal (≥ 3) total EAT-10 points were determined in 88.9% (24/27) and 11.1% (3/27), respectively, of the control group, in 55.2% (16/29) and 44.8% (13/29) of Group 1, in 70.6% (12/17) and 29.4% (5/17) of Group 1a, and in 33.3% (4/12) and 66.7% (8/12) of Group 1b. A statistically significant difference was determined between the control group and Group 1 and Group 1b in respect of abnormal (≥ 3) EAT-10 total points (p = 0.007, p = 0.001, respectively). No statistically significant difference was determined between the control group and Group 1a (p = 0.227). Problems (EAT point ≥ 1) in item 4 (swallowing solids takes extra effort) were experienced by 13 (44.8%) patients in Group 1, 9 (75%) patients in Group 1b, and 5 (18.5%) subjects in the control group (p < 0.05). These results demonstrated that unilateral PAICA does not significantly affect swallowing, whereas bilateral PAICA created a significant negative effect. These patients experience more problems when swallowing solid food.

Laryngoscopic Examination During the COVID-19 Pandemic: Turkish Voice Speech and Swallowing Disorders Society and Turkish Professional Voice Society Recommendations. Turk Arch Otorhinolaryngol 2020; 58:274-278. [PMID: 33554203 PMCID: PMC7846307 DOI: 10.5152/tao.2020.5719] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2020] [Accepted: 09/15/2020] [Indexed: 01/07/2023] Open
Abstract
COVID-19 is highly transmissible and spreads rapidly in the population. This increases the occupational risk for health care workers. In otolaryngology clinic practice, patients with upper respiratory tract infection symptoms are common. Also, routine head and neck examinations such as oral cavity examination, nasal/nasopharyngeal examination, or video laryngostroboscopic evaluation are highly risky because of the aerosol formation. To emphasize this issue, two leading otolaryngology organizations in Turkey; 'Voice Speech and Swallowing Disorders Society', and 'Professional Voice Society' gathered a task force. This task force aimed to prepare a consensus report that would provide practical recommendations of the safety measurements during routine clinical care of laryngology patients. To fulfill this, universal aim, on the 2nd and 9th of May 2020, two web-based meetings were conducted by 20 expert physicians. This eighteen items list was prepared as an output.

The Role of Nutritional and Dietary Habits in Etiology in Pediatric Vocal Fold Nodule. J Voice 2020; 36:882.e1-882.e7. [PMID: 33012629 DOI: 10.1016/j.jvoice.2020.09.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 09/02/2020] [Accepted: 09/14/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES In pediatric pediatric vocal fold nodule (VFN) patients, different causes have been suggested in the development of the vocal cord nodule, including laryngopharyngeal reflux (LPR). It is known that the content of consumed foods, obesity, and other dietary behaviors are among the risk factors for the development of reflux. The aim of this study was to evaluate dietary and food consumption habits in pediatric VFN patients. METHODS This prospective-controlled study included 50 children with VFNs (age range 5-14 years) and 50 age-matched children without any voice disorders as a control group. BMI values of each participant were evaluated according to age-percentile range. The voice usage habits and personality structure of all the children were questioned. All patients underwent laryngeal examination and voice analysis. The Turkish Pediatric Voice Handicap Index (t-PVHI) and Child Voice Handicap Index-10 (t-CVHI) were completed by patients or their parents. The examination findings of all patients were evaluated with the reflux finding score (RFS), and their complaints were questioned with the reflux symptom index (RSI). In addition, eating and drinking at night, fast eating and excessive food consumption habits and the frequency of consumption of packaged foods defined as junk food, carbonated beverage were questioned. The data obtained were compared statistically between the two groups. RESULTS There was no significant difference between the study and control groups in terms of age, gender distribution, median BMI value, voice usage habits, and personality structure. In the study group, t-PVHI, t-CVHI, jitter, schimmer values, the mean RFS, and RSI scores were significantly higher than those of the control group. The number of children with high consumption of junk food and carbonated drinks was higher in the study group. There was no significant difference between the two groups in terms of dietary habits. CONCLUSION Food consumption habits may play a role in childhood voice problems in this population.

Reliability and Validity of the Turkish Version of the Glasgow-Edinburgh Throat Scale: Use for a Symptom Scale of Globus Sensation in Turkish Population. Turk Arch Otorhinolaryngol 2020; 58:41-47. [PMID: 32313894 DOI: 10.5152/tao.2020.4686] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/20/2019] [Indexed: 11/22/2022] Open
Abstract
Objective In this study, we aimed to translate the Glasgow-Edinburgh Throat Scale (GETS) into Turkish and test its reliability and validity. Methods A total of 69 patients with globus sensation and no signs of otolaryngologic or gastroenterological disease in etiology were included in the study. The patients were asked to complete the translated Turkish version (GETS-T) of GETS and the Hospital Anxiety and Depression Scale (HADS). Results The Cronbach's alpha coefficient of the patients in the study group was calculated based on the 12 questions in the GETS-T scale and found as 0.868. The correlation between the GETS-T total score and the total HADS score in the study group was found to be very low and statistically insignificant. As a result of factor analysis, it was found that the first 10 problems in GETS-T were divided into two sub-groups, unlike GETS. Conclusion Translation of GETS into Turkish (GETS-T) showed high reliability and validity, suggesting that translation and cross-cultural adaptation was appropriate. The GETS-T can be used in studies about globus pharyngeus in future.

Abstract
INTRODUCTION Concha bullosa (CB), which is pneumatization of the concha, is one of the most commonly seen anatomic variations of the lateral nasal wall. OBJECTIVE To investigate the effects on olfactory function of lateral turbinectomy and crushing methods used in the surgical treatment of CB. METHODS The study included a total of 47 patients operated on for a diagnosis of CB and nasal septum deviation. The patients comprised 22 females and 25 males, with bilateral CB in 18 cases and unilateral in 29 cases. Intervention was made to a total of 65 CB. The cases were separated as those applied with septoplasty and lateral turbinectomy in group 1 (n = 34) and those applied with the septoplasty and crushing method in group 2 (n = 31). The olfactory function of the patients was evaluated preoperatively and at 3 months postoperatively with the Brief Smell Identification Test. RESULTS A statistically significant increase was determined in the postoperative smell test results compared with the preoperative values in both group 1 (P = .021) and group 2 (P = .001). When the change in the smell test results from preoperative to postoperative was compared between the groups, the increase in group 2 was determined to be statistically significantly greater (P = .002). CONCLUSION The results of this study showed that the crushing method in surgical treatment of CB increased olfactory functions more than the lateral resection method, and as the improvement in olfactory functions was greater, this demonstrated that only increasing the nasal cavity is not sufficient and the nasal mucosa should be protected as far as possible.

Abstract
BACKGROUND Although tacrolimus is one of the essential drugs used for the prevention of rejection in kidney recipients, target trough levels are not well established. In this study, we aimed to investigate the association between average tacrolimus trough levels (TTLs) of the first month after transplantation and biopsy-proven acute rejection (BPAR) during the first 12 months after transplant. METHODS A total of 274 patients who underwent kidney-alone transplantation between 2002 and 2014 were enrolled in the study. Average TTLs of the first month were assessed by means of receiver operating characteristic (ROC) curve analysis to discriminate patients with and those without BPAR. Univariate and multivariate Cox proportional hazards models were used to determine the effect of average TTLs of the first month on BPAR. RESULTS According to ROC curve analysis, the highest area under the curve (AUC) was obtained from 8 ng/mL (AUC = 0.73 ± 0.11; 95% confidence interval [CI], 0.62-0.84). Forty-two (31.8%) of the 132 patients with average TTLs <8 ng/mL and 13 (9.1%) of 142 patients with ≥8 ng/mL had BPAR during the first 12 months after transplant (P < .001). In univariable analysis, average TTLs of the first month <8 ng/mL were associated with higher risk of BPAR (P < .001), and the significance remained in Cox multivariable analysis (hazard ratio, 2.79; 95% CI, 1.76-3.82; P = .001). No significant differences were observed in the glomerular filtration rate, cytomegalovirus, BK viremia, or BK nephropathy between groups at post-transplant month 12. CONCLUSIONS Keeping the average TTLs of the first month after transplantation at ≥8 ng/mL not only prevents BPAR occurrence but also minimizes the toxic effects of the use of a single-trough level.

Abstract
Objective A rhinolith is a rare entity affecting all people in all age groups. It is defined as a mineralized foreign body. The purpose of the present study was to reveal the distribution in age and gender and the localization, side, and prominent symptoms of rhinoliths to identify the risk groups and characteristics of the rhinoliths in a large case series. Methods A retrospective review was performed from the medical charts of 28 patients who were diagnosed with rhinolith and underwent surgery between May 2011 and January 2015 in Ankara Research and Training Hospital. All data, including age, gender, duration of symptoms, localization of the lesion and accompanying pathologies, were documented. Results In total, 28 patients (18 females and 10 males) with a mean age of 26.2±16.6 (5-62) years who were diagnosed with rhinolithiasis were reviewed. Nasal obstruction (71.4%) and nasal discharge (64.3%) were the most common complaints. The rhinolith was located in the right nasal cavity in 24 patients and in the left in four; this difference was statistically significant (p<0.001). There were 11 accompanying pathologies including nasal septal deviation (n=6), nasal polyposis (n=2), concha bullosa (n=2), and adenoid vegetation (n=1). In 21 (75%) patients, the most common site was the nasal base of the cavity between the inferior turbinate and the nasal septum. Conclusion If unilateral right-sided nasal obstruction with foul-smelling purulent discharge is detected in a young adult and a nasal examination reveals a mass in the floor of the cavity, a rhinolith should be strongly considered in the differential diagnosis.

Abstract
OBJECTIVE To evaluate the effectiveness of enoxaparin sodium (ES) on experimentally-induced myringosclerosis in rats. MATERIALS AND METHODS Twenty Wistar albino-type rats weighing up to 250-300 g each were randomized into four groups containing five rats each and were then bilaterally myringotomized. The control group (n=5) received intratympanic serum physiologic injections, whereas ES2 (n=5), ES4 (n=5), and ES6 groups (n=5) received intratympanic ES of 2000 IU, 4000 IU, and 6000 IU, respectively, for 10 days after myringotomy. Rats were sacrificed at 60 days after intratympanic application and were then prepared for histopathologic evaluation. RESULTS As for tympanic membrane hyaline degeneration, there were statistically significant differences among the control, ES2, ES4, and ES6 groups (p<0.05). As for fibrosis formation on tympanic membranes, a statistically significant difference was observed among the control and study groups; however, although not statistically significant, the formation of fibrosis was slowed down in the ES2 and ES4 groups compared with the control group. The control and study groups did not show any significant difference for calcification, hyperemia, and tympanic membrane thickening (p>0.05). CONCLUSION Although our study and control groups comprised limited number of animals, and only one parameter demonstrated a statistically significant difference between the groups, ES may have an ameliorating effect on myringosclerosis induced by myringotomy in the tympanic membranes of rats. ES proved to be effective in the prevention of hyaline disc formation. Further studies should be conducted for better understanding of the effects of low-molecular-weight heparin (LMWH) (i.e., enoxaparin) on myringosclerosis.

Abstract
BACKGROUND Nasal mucociliary clearance has an important role in voiding the airways from inhaled foreign substances. This activity could be disturbed by environmental factors such as radiofrequency radiation. The aim of the present study was to investigate short-term and relatively long-term effects of 2100-MHz radiofrequency radiation emitted by a generator, simulating a 3G-mobile phone, on the nasal septal mucosa and mucociliary clearance in rats. METHODS Thirty Wistar albino rats were divided into 4 groups. There were 6 rats in Group A and Group B, which served as the control groups (10-day and 40-day groups, respectively). Groups C (10-day exposure) and D (40-day exposure) were both composed of 9 rats; they comprised the radiofrequency radiation exposure groups. The rats in groups C and D were exposed to 2100-MHz radiofrequency radiation emitted by a generator, simulating a 3G-mobile phone, 6 hours/day, for 10 or 40 days, respectively. After exposure, nasal mucociliary clearance was measured by rhinoscintigraphy. After euthanization, the nasal septa of the animals were removed, and tissue samples of the nasal mucosa were examined using a transmission electron microscope. RESULTS The differences in mucociliary clearances between groups A and C, groups B and D, and groups C and D were found to be statistically significant (p = 0.005, p < 0.001, p < 0.001, respectively). Although there were no histopathological abnormalities in the control groups, the exposure groups showed a number of degenerated and apoptotic cells, ciliary disorganization and ciliary loss in the epithelial cells, epithelial metaplasia, alteration of normal chromatin distribution and karyolysis in nuclei, changes in the basal cells, and lymphocytic infiltration. The histopathological changes were more severe in group D. CONCLUSION Radiofrequency radiation at 2100 MHz damaged the nasal septal mucosa, and disturbed the mucociliary clearance. Ciliary disorganization and ciliary loss in the epithelial cells resulted in deterioration of nasal mucociliary clearance.

Abstract
OBJECTIVES/HYPOTHESIS This experimental study in a rabbit model aimed to investigate the use of glass ionomer cement as a tissue adhesive on the dorsal L-strut. STUDY DESIGN Sixteen adult male New Zealand White rabbits were used. The rabbits were equally divided into two groups as the control and the study groups. METHODS The nasal septum was exposed through a superior approach. A graft was harvested preserving an L-strut cartilage. In the control group, a vertical incision was performed on the dorsal part of the L-strut to divide it into two cut ends, and the graft was sutured to the cut ends with 5-0 polydioxanone suture. In the study group, the reconstruction of the dorsal L-strut was made by fixing the graft to the cut ends with glass ionomer cement as the tissue adhesive. At 2 months, the rabbits were sacrificed. The nasal septum was removed for histopathological examination. RESULTS No foreign body giant cells or acute inflammation were determined in the rabbits. The study group had less pronounced chronic inflammation. Comparison of the groups revealed that parameters regarding vascularization, cartilage proliferation, and new cartilage cells were statistically significant different between the two groups (P = .010, P = .010, P = .028, respectively). More vascularization, cartilage proliferation, and new cartilage cells were seen in the study group. CONCLUSIONS Glass ionomer cement was effective for the reconstruction of the dorsal L-strut without any foreign body reaction, cartilage necrosis, or marked inflammation in rabbits, and it may be a potentially beneficial alternative to suture fixation.

Abstract
OBJECTIVES/HYPOTHESIS To determine if there is a relationship between Helicobacter pylori colonization in the pharynx mucous membrane and chronic nonspecific pharyngitis. STUDY DESIGN A prospective clinical study. METHODS Seventy patients with chronic pharyngitis and 20 healthy control subjects were examined with polymerase chain reaction (PCR) and culture for H. pylori colonization in the pharynx mucous membrane between March 2008 and October 2008. Patients with pharyngitis were seperated into two groups (35 patients in each) by using C-14 urea breath test, according to the presence of gastric H. pylori infection. RESULTS In the control group, none of the patients had H. pylori in the pharynx. In the chronic pharyngitis group, in 12 patients (34.3%) with gastric H. pylori infection and in seven patients (20%) without gastric infection, H. pylori colonization in pharynx mucosa was determined with the PCR method. In only two of chronic pharyngitis patients (5.8%), H. pylori infection was detected with culture. In the pharynx mucosa, the H. pylori infection rate was significantly higher in the chronic pharyngitis groups than in the control group (P = .002 between C-14 positive and control groups, P = .040 between C-14 negative and control groups). There was not a significant difference in H. pylori colonization in the pharynx of patients who had chronic pharyngitis with or without gastric ailments and H. pylori infection (P = .179). CONCLUSIONS Chronic nonspecific pharyngitis without gastric H. pylori infection is significantly related to H. pylori colonization in the pharynx, and gastric involvement increases the rate of this spread. The gold standart for detection of H. pylori infection is the PCR method.

Abstract
Liver transplantation for end-stage liver disease is the treatment of choice in current surgical practice. However, the shortage of cadaveric organs has limited this treatment option for many years. Living donor liver transplantation (LDLT) may be an option to overcome the organ shortage. In the present series we report a single-center experience with 39 LDLT performed from March 2000 to June 2003. The main indications for LDLT was hepatitis B cirrhosis (11 patients). The recipient hepatectomy was performed with caval preservation. The hepatic vein anastomosis was performed either to recipient hepatic vein or inferior vena cava. The portal vein anastomosis was performed either to the recipient's main or right portal branch. Biliary diversion was performed to the recipient biliary ducts if possible, otherwise to a jejunal loop in Roux-en-Y fashion. The survival rate at the end of one year was 71%. The leading cause of mortality was sepsis in five patients. Biliary complications developed in 20% of the recipients. All bile leaks were from the Roux-en-Y hepaticojejunostomy. Hepatic artery thrombosis was diagnosed in four patients by loss of hepatic blood flow on Doppler ultrasound. LDLT is a major surgical option for end-stage liver disease, particularly for countries with low rates of organ donation. However, there are technical challenges to be overcome such as small vessels from segmental grafts and multiple small bile ducts.

Abstract
The incidence of arteriovenous fistulae (AVF) is quite rare in the head and neck region comprising less than 4% of all the traumatic AVF encountered elsewhere in the body. A 42-year-old man presented with a palpable thrill in the cervical region and headache. He had a shotgun injury 10 years ago and had no problem until the previous three months. Diagnosis of a high output traumatic AVF between right common carotid artery and internal jugular vein was made arteriographically. Presence of a neighbouring traumatic aneurysm on the common carotid artery and 9 mm diameter of the fistula tractus suggested open surgery. At the operation ligation of the tractus and aneurysmorraphy was performed and the patient was discharged in the third postoperative day. He has still no problem. This case documented that a shotgun injury even 10 years later may result with an AVF.

Abstract
In this first clinical trial femoral vein transposition (FVT) was prospectively compared with its "graft" counterpart. Patients requiring vascular access due to occluded central veins were divided into two groups: group I (n = 17) underwent femoral loop grafts and group II (n = 15), FVT. Complications were recorded prospectively and patency rates were compared by the Kaplan Meier method with statistical comparisons by Mann Whitney U and chi-square tests as appropriate. Between 1999 and 2003 30 patients underwent 32 operations. Mean follow-up was 8.9 months in group I and 6.8 months in group II (P >.05). Three group I patients developed a steal, requiring closure of the fistula in one. Five group II patients developed a steal, requiring closure of the fistula in one. The incidence of steal was similar in both groups (P >.05). The infection rates were similar: 35.3% and 26.7% in group I versus group II (P >.05), respectively. Among the six infections in group I, four patients required excision of the graft due to infection, whereas only one arteriovenous fistula (AVF) was closed in group II for infection. The 1-year primary patency rate in group I was 37.5% versus 86.7% in group II (P <.05). In conclusion, Femoral AVF grafts have been condemned because of the unacceptable high rate of septic complications. FVT obviates the need for a graft and has fewer infectious problems and better patency rates.

Abstract
The rate of patients with exhausted upper extremity arteriovenous fistula (AVF) sites who have lost all chances for a conventional upper extremity AVF has been increasing in line with the general increase in the hemodialysis patient population. In this prospective study, we report the early and late follow-up results of "exotic" AVFs in which central veins are used for the outflow. Patients having no chance for an upper extremity AVF based on previous catheterization, surgical AVF history, detailed physical examination, and radiological assessment, were included in the study. Between June 1999 and January 2003, 27 central AVFs were created with a 6 mm synthetic vascular graft in 26 patients. The inflow artery was the proximal axillary artery in all except one. All but one operation was done by the same surgeon. The outflow vein was the internal jugular vein in 16 and infraclavicular axillary vein in 11 cases. One-year primary and secondary graft patency rates were 33.33 +/- 10.49 and 57.06 +/- 11.29, respectively. The early complications were facial edema and hemiparesis, both of which resolved spontaneously. The only late complication, pseudoaneursym, was treated by a graft interposition. In selected patients who have no suitable upper extremity vessels for an AVF, the central veins may be used with an acceptable success rate. Another advantage of this procedure is the avoidance of undesired femoral interventions; sometimes it may be the only opportunity and lifesaving for the patient.

Abstract
One of the major challenges in living donor liver transplantation (LDLT) is short and small vessels (particularly the hepatic artery), particularly in segmental liver grafts from living donors. In the present study we report an alternative surgical technique that avoids interpositional vessel grafts or tension on the connection by anastomizing the allograft hepatic vein to the recipient inferior vena cava in a more caudate location. From March 2000 to January 2003, 28 patients (11 women/17 men) underwent 28 LDLT. Until June 2001, the preferred technique for hepatic vein anastomosis was end-to-end anastomosis between the allograft hepatic vein and the recipient hepatic vein (HV-HV) (n = 10). Thereafter an end-to-side anastomosis was performed between allograft hepatic vein and recipient inferior vena cava (HV-IVC) (n = 18). The level of venotomy on the recipient vena cava was decided according to the pre-anastomotic placement of the allograft in the recipient hepatectomy site with sufficient width to have an hepatic artery anastomosis without tension or need for an interposition graft during hepatic artery and portal vein anastomoses. Except the right lobe allograft with anterior and posterior portal branches, all portal and hepatic artery anastomoses were constructed without an interposition graft or tension in the HV-IVC group. Only one hepatic artery thrombosis developed in the HV-IVC group. As a result, this technique may avoid both hepatic artery thrombosis and the use of interposition grafts in living donor liver transplantation.

Abstract
We present the case of a 56-year old man who presented with a large, well circumscribed cystic mass in the gastrocolic ligament. The histopathological study revealed an epithelioid leiomyosarcoma. Epithelioid leiomyosarcomas are generally solid tumours of the stomach. It is uncommon in the gastrocolic ligament and in a cystic formation. Preoperative diagnosis with ultrasound, computerized tomography and endoscopy was not made. Complete surgical resection of the mass was performed. Histopathological study confirmed the diagnosis of epithelial leiomyosarcoma. Two years after surgery, clinical and radiological examinations of the patient were normal.

Abstract
UNLABELLED The purpose of this study was to evaluate the efficacy of lymphoscintigraphy and the surgical gamma probe (SGP) with peritumoral injection of 99mTc MIBI in sentinel lymph node (SLN) detection in breast cancer regardless of whether metastatic or not. METHOD Thirty patients with T1/ T2 breast cancer had peritumoral injections of 99mTc MIBI (74 MBq/0.2 ml at 4 different locations) at 2, 6 and 24 hours before surgery. Anterior, anterolateral, and lateral spot images were taken at 10, 30, 45, 60 and 120 minutes. Counts were collected from the injection site, affected breast tissue, internal mammaries, axillary and supraclavicular regions, and the contralateral side. Peritumoral blue dye was also injected at surgery. The first lymph nodes with counts twice the background tissue and/or with blue dye uptake were surgically isolated, and histopathological evaluations were made. Modified radical mastectomy was performed on all patients. RESULTS 23/30 patients had lymph nodes in scintigrams and the sentinel lymph nodes were identified with SGP in 25/30 patients. CONCLUSION Lymphoscintigraphy and subsequent SGP detection with peritumoral injection of 99mTc MIBI can be used for identifying SLN in breast cancer.

Abstract
OBJECTIVE Behçet's disease (BD) is a multisystemic disease of unknown etiology, characterized by aphthous ulcerations and uveitis, that is common in the Turkish population. Venous involvement is observed in 25% of the cases. While superficial thrombophlebitis is the most common finding, deep venous thrombosis (DVT) follows it. Hyperactivity in the coagulation pathway, hypoactive anticoagulation mechanisms, or faulty fibrinolysis generate a tendency for thrombogenesis. Mutations of the genes involved in these pathways may cause predisposition to thrombosis. METHODS Possible roles of methylenetetrahydrofolate reductase (MTHFR) gene C677T, factor V (FV) gene G1691A (Leiden), and prothrombin gene G20210A polymorphisms in venous thrombogenesis were evaluated in patients with BD; 100 healthy people, 30 BD patients without DVT, 30 BD patients with DVT, and 30 patients with idiopathic DVT were studied with the restriction fragment length polymorphism method for these 3 polymorphisms. The frequencies of these mutations for each group, separately and in combinations, are described. RESULTS Among the 3 mutations, FV Leiden mutation was found to be a risk factor for DVT. An association between FV Leiden mutation and BD was likely, but FV Leiden mutation did not increase the risk for deep venous thrombogenesis in BD patients. MTHFR gene C677T mutation does not increase risk of DVT in BD either alone or combined with FV Leiden mutation. CONCLUSION Although a thrombotic tendency is one of the major characteristics of BD, we found no association between these 3 thrombogenetic mutations and BD patients with thromboses.

Abstract
Behçet disease (BD) is an inflammatory illness that may attack several systems. Vascular involvement with thrombosis is one of the basic characteristics of this disease. The etiology of thrombosis tendency in BD has not been understood well. In this study, the role of primary coagulation parameters in patients with BD who have thromboembolic events was evaluated. In addition, the relation between the clinical activity of the disease and these parameters was compared. A total of 96 patients with a diagnosis of BD were studied at Ankara University, Medical School, Department of General Surgery and Behçet Center. BD patients were separated into two groups with respect to vascular involvement. Group A contained 22 patients with vascular attacks, and group B contained 74 patients without vascular attacks. In addition, 25 healthy persons comprised the control group (group C). The coagulation parameters assessed included protein C, protein S, antithrombin III activity, fibrinogen level, prothrombin time (PT), and partial thromboplastin time (PTT). There were no differences among the three groups with respect to protein C, protein S, fibrinogen, PT, and PTT values (p > 0.05). The antithrombin III value was found to be high in BD patients compared to those in the control group (p = 0.011). There was no difference regarding the antithrombin III value between BD patients with or without vascular attacks (p = 0.954). There was no correlation between the activity of disease and coagulation parameters (p > 0.05), but a positive correlation was seen between the duration of illness and vascular involvement. Fifty percent of patients who had had BD more than 8 years had vascular involvement (p = 0.002). We could not determine a specific pathology in relation to coagulation parameters that could explain the etiology of thrombosis in patients with BD. The elevated antithrombin III levels in patients with BD (compared to controls) may be due to a compensatory defense mechanism against increased procoagulant activity. There was a correlation between the duration of illness and vascular involvement.

Abstract
AIM to determine whether Behçet's disease affects haemostatic function. SETTING University Hospital, Turkey. PATIENTS one hundred and twenty-seven consecutive patients with Behçet's disease, 34 of whom with a history of vascular involvement. METHODS prothrombin fragment 1+2 tissue plasminogen activator, protein S and C, antithrombin, fibrinogen, von Willebrand factor, thrombomodulin and prothrombin time (PT) were measured in patient plasma. RESULTS soluble thrombomodulin was significantly lower and von Willebrand factor (vWF) and tissue plasminogen activator (tPA) significantly higher in Behçet's patients. Patients with vascular involvement showed the highest levels of vWF and tPA. There was no activation of coagulation, not even in patients with an active disease at the time of sampling. CONCLUSION there were indirect signs of endothelial activity or damage, particularly in patients with vascular involvement. Coagulation was not activated.

Abstract
Authors report a case of a 29-year-old male with primary malignant lymphoma of the appendix with involvement of lymph nodes in the mesenteries. Surgical intervention was performed, adjuvant chemotherapy was applied. No recurrences, metastases or complaints occurred after one year of follow-up. The case is of interest due to the clinical and histopathological diagnostic problems as well as the dimension of the metastatic lymph node in the ileal mesentery.

Abstract
Vascular involvement in Behçet's disease has been reported in 7-40% of patients in the literature and nearly 8% of these will have serious vascular complications during follow-up. So far, little information is available on the extent of vascular involvement in patients with Behçet's disease who are free of vascular symptoms. The study comprised 34 individuals with Behçet's disease who were free of vascular symptoms and 47 healthy volunteers. Both groups underwent non-invasive peripheral vascular examination consisting of Doppler, photoplethysmography, and segmental pressure measurements and determination of ankle-brachial pressure and femoro-brachial pressure indices. Venous insufficiency was detected in 22 of 68 lower extremities examined in the Behçet's disease group and in ten of 94 in the controls (P < 0.001). The number of extremities with an ankle-brachial pressure index of less than 1.00 for both the anterior and posterior tibial arteries, was significantly higher in the Behçet's disease group (P < 0.001). The femoro-brachial pressure index was significantly higher in the controls than in the Behçet's disease group (1.32 versus 1.23 for the right leg, P < 0.05; 1.31 versus 1.22 for the left leg, P < 0.03). Vascular symptom-free patients with Behçet's disease seem to have a high incidence of peripheral vascular involvement compared with healthy controls.

Abstract
Behçet's disease is a multisystemic disorder characterized by recurrent ulcers of the mouth and genitalia and relapsing iritis. Four types of vascular lesion are recognized in Behçet's disease: arterial occlusions, aneurysms, venous occlusions, and variceal development. The incidence of vascular involvement reported in the literature ranges from 7% to 29%. The aim of this study was to determine the rate of vascular involvement in Behçet's disease at our hospital between 1983 and 1992. Of 1200 patients with Behçet's disease, 173 (14.4%) had venous manifestations and 19 (1.6%) had arterial manifestations (in some patients more than one organ was involved). In the group of patients with venous manifestations, there were 154 (12.8%) with venous thrombosis, 17 (1.4%) with vena cava superior syndrome, 5 (0.4%) with inferior vena cava syndrome, 5 (0.4%) with varices, 2 with upper extremity venous thrombosis, 1 with internal jugular vein thrombosis, 1 with cavernous sinus thrombosis, and 1 with hepatic vein thrombosis. In the arterial manifestation group there were 7 femoral, 3 abdominal, 3 popliteal, 2 iliac, 2 pulmonary, 1 axillary, and 1 carotid artery aneurysm as well as 3 arterial occlusions. We concluded that vascular surgeons dealing with young adults should bear Behçet's disease, an uncommon clinical entity, in mind.
