AN EVALUATION OF THE OCCUPATIONAL EXTERNAL RADIATION EXPOSURE OF PERSONNEL IN NUCLEAR MEDICINE PRACTICES (2010-2020).

The aim of this study was to examine the radiation doses received by personnel working in the Nuclear Medicine Department between 2010 and 2020. The data obtained were compared with the dosages recommended by international authorities. The UNSCEAR 2008 report stated that the worldwide annual average effective dose to which personnel were exposed when monitored between 2000 and 2002 was 0.70 and 1.40 mSv, respectively. In this report, 0.7 mSv refers to the dose of all monitored personnel, and 1.4 mSv refers to the dose above the detection limit. In this study, the annual average effective dose value for personnel exposed to radiation was calculated as 1.65 mSv. This value represents the dose above the detection limit. Although the individual dose results are below the recommended annual dose limit, it should not be forgotten that more effort should be made to reduce radiation doses using the as low as reasonable achievable principles.

Isolation and molecular identification of industrially important enzyme producer yeasts from tree barks and fruits.

This study aimed to identify the yeast strains associated with the tree bark samples collected from the Aegean and Marmara regions and from rotten fruit samples. Fifty-one yeast strains were successfully isolated and screened for their abilities to produce industrially important extracellular enzymes. Thirty isolates demonstrated ability to produce at least two different enzymes and were selected for subsequent molecular identification using sequence analysis of ITS region and D1/D2 domain of the 26S rDNA. The most prevalent strains belonged to Papiliotrema laurentii (%23), Papiliotrema terrestris (%13) and Candida membranifaciens (%10). Papiliotrema laurentii and Papiliotrema terrestris recorded the highest enzymatic activities for all the screened enzymes. To the best of our knowledge, this is the first report that identifies the yeast strains associated with the tree barks of Turkey and among the limited comprehensive studies that screened considerable number of isolates for their ability to produce several industrially important enzymes.

Inhibition of Salmonella enteritidis biofilms by Salmonella invasion protein-targeting aptamer.

The current study aimed to assess the inhibitory effect of a DNA aptamer (Apt17) which targeted Salmonella invasion proteinA (SipA). The effect of Apt17, on biofilm formation by two Salmonella enteritidis strains, was tested either separately or in combination with ampicillin at different Sub MIC concentrations. Maximum inhibitory effect equivalent to 24.34% and 26.81% was recorded when Apt17 was co-incubated with S. enteritidis TM 6 and S. enteritidis TM 68 respectively for 13 h. The inhibitory effect of Apt17 was also confirmed with Triphenyl Tetrazolium Chloride. Under Scanning Electron Microscope, the presence of Apt17 resulted in altered three dimensional structure. While the treated cells of S. enteritidis TM 6 were arranged as monolayers, the sessile aggregates of S. enteritidis TM 68 appeared thinner and exhibited less surface coverage when compared to control. Moreover, the treated cells lost their exopolysaccharide matrix. The co-incubation of Apt17 with ampicillin MIC/10 for 24 h, inhibited the biofilms of S. enteritidis TM 6 and S. enteritidis TM 68 by 12.5 and 20.9% respectively. This study demonstrated quantitative and qualitative antibiofilm effect of Apt17 against the biofilms of two Salmonella enteritidis strains. According to our knowledge, this is the first study employing an aptamer that targets SipA protein to inhibit biofilm formation in Salmonella.

The effect of carbon, nitrogen and iron ions on mono-rhamnolipid production and rhamnolipid synthesis gene expression by Pseudomonas aeruginosa ATCC 15442.

Pseudomonas spp. are the main producers of rhamnolipids. These products have applications in pharmaceuticals, cosmetics, food industry and bioremediation. The biosynthesis of rhamnolipids is influenced by nutrient composition, pH and temperature. In this study, the impact of nutrients on the expression levels of rhamnolipid synthesis genes was evaluated in P. aeruginosa ATCC 15442. Glucose and glycerol were used as carbon sources; while, NaNO3, NH4NO3 and yeast extract/peptone were employed as nitrogen sources. The effect of different concentrations of Fe2+ and Fe3+ on rhamnolipid synthesis genes was also evaluated. Highest biosurfactant production was obtained in minimal medium supplemented with glucose, NaNO3 and Fe2+. Two rhamnolipid synthesis genes, rhlA and rhlB, were amplified with PCR. CapLC ESI-Ion trap-MS/MS detected only mono-rhamnolipid Rha-C10-C10 in the extract. Although similar induction levels were recorded in the presence of 0.05 g/L iron ions, the presence of Fe2+ resulted in higher expression levels than Fe3+ at concentrations equivalent to 0.025 and 0.075 g/L.

Impact of sodium lactate, encapsulated or unencapsulated polyphosphates and their combinations on Salmonella Typhimurium, Escherichia coli O157:H7 and Staphylococcus aureus growth in cooked ground beef.

Foodborne illnesses affect the health of consumers worldwide, and thus searching for potential antimicrobial agents against foodborne pathogens is given an increased focus. This research evaluated the influence of sodium lactate (SL), encapsulated (e) and unencapsulated (u) polyphosphates (PP; sodium tripolyphosphate, STP; sodium acid pyrophosphate, SPP), and their combinations on Salmonella Typhimurium, Escherichia coli O157:H7 and Staphylococcus aureus growth in cooked ground beef during 30 day storage at 4 or 10 °C. pH, water activity (aw), oxidation-reduction potential (ORP) and S. Typhimurium, E. coli O157:H7 and S. aureus counts were determined. S. Typhimurium was not found in SPP-SL combination groups after 30 day storage at 4 °C (P <0.05). Lower S. Typhimurium levels were determined in only SL containing groups stored at 10 °C than group with only tested microorganism (MO, P < 0.05). Although there was no change in S. Typhimurium load in all SL incorporated groups during 10 °C storage, S. Typhimurium count increased in other groups (P < 0.05). E. coli O157:H7 in MO and STP groups showed an increase at 4 °C, whereas it decreased in SPP-SL combination groups (P < 0.05). A gradual increase in E. coli O157:H7 at 10 °C was determined in MO and only PP incorporated groups, whereas there was a decrease in STP-SL or SPP-SL combination groups (P < 0.05). E. coli O157:H7 count was stable in SL containing groups during 10 °C storage. A gradual decrease in S. aureus was determined in all treatments at 4 °C, whereas S. aureus count increased in MO and uSTP groups during 10 °C storage (P < 0.05). There was no change in S. aureus level in only eSTP or uSPP or ueSTP containing groups at 10 °C, meantime it decreased in other groups (P < 0.05). The lowest S. aureus load was achieved by uSPP-SL or eSPP-SL or ueSPP-SL combinations after 30 days at both storage temperatures (P < 0.05). In general, pH was higher in samples with STP than those with SPP and control (P < 0.05). The lowest aw was generally obtained in all SL containing groups at both storage temperatures (P < 0.05). Lower ORP was determined in all PP incorporated groups during storage at both temperatures compared to others (P < 0.05). ORP in all treatments generally increased (P < 0.05) during storage at both storage temperatures. This study showed that encapsulation is not a factor affecting antimicrobial efficiency of PP and using PP-SL combinations have synergistic effect on reducing the viability of S. Typhimurium, E. coli O157:H7 and S. aureus and their subsequent growth ability in cooked ground beef.

Single-stranded DNA (ssDNA) Aptamer targeting SipA protein inhibits Salmonella Enteritidis invasion of intestinal epithelial cells.

Salmonella Enteritidis is an important pathogen that can invade the intestinal cells of its host causing salmonellosis. SipA protein, an effector protein secreted by T3SS, maintains invasion of host cells more efficient. Thus, inhibitory aptamers against SipA protein were developed using magnetic bead-based Systematic Evolution of Ligands by Exponential Enrichment (SELEX) method. The enriched sequences were obtained after 9 SELEX rounds. Among which, an aptamer namely Apt17 displayed Kd values equivalent to 114.9 and 63.4 nM at 27 °C and 37 °C, respectively. The effect of Apt17 on adhesion and invasion of Caco-2 cells by the tested strains was determined. While the adhesion and invasion of Salmonella Enteritidis TM 6 were inhibited by 70% and 37.7%, those of Salmonella Enteritidis TM 68 were inhibited by 45.71% and 39.5% respectively. These results represent a corner stone for future studies that could aim to develop putative inhibitors against Salmonellosis.

Effects of heat-treated hempseed supplementation on performance, egg quality, sensory evaluation and antioxidant activity of laying hens.

1. This study was conducted to determine the effects of raw and heat-treated hempseed (HHS, Cannabis sativa L.) on performance, egg quality and antioxidant activity in laying hens. 2. A total of 108 laying hens, aged 36 weeks, were divided into three treatment groups with 12 replicates and each replicate contained three laying hens. The treatments were as follows: (1) Control (no hempseed), (2) 15% raw hempseed (RHS) in diet and (3) 15% HHS in the diet. Experiments lasted for 12 weeks. 3. Feed intake of the RHS group was lower than those of the control and HHS groups. Egg weight, egg mass, shell weight, shell surface area and shell thickness of the HHS group were significantly (P < 0.05) higher than that of the RHS group. Roche (DSM) colour fan values of the RHS group were higher than that of the HHS group (P < 0.01). 4. Palmitic, palmitoleic and oleic acids of egg yolk were significantly (P < 0.05) decreased in the RHS and HHS groups; however, linoleic, α-linolenic and docosahexaenoic acids (DHA) of egg yolk increased (P < 0.05) for both treatment diets compared to the control group. 5. Both RHS and HHS supplementation to layer diets did not influence malondialdehyde (MDA) and superoxide dismutase (SOD) activity and blood lipid profile. 6. It was concluded that HHS was superior in improving the egg quality of laying hens as compared to the RHS.

The Alvarado Score is accurate in pregnancy: a retrospective case-control study.

BACKGROUND: Acute appendicitis is the most frequent abdominal condition that requires non-obstetric surgical intervention during pregnancy. This study aims to scan pregnant patients operated on for acute appendicitis to evaluate the efficiency of using the Alvarado Score (AS) for diagnosis. METHODS: Our study included 48 pregnant patients who were pre-diagnosed with acute appendicitis and operated on at our department of general surgery from January 2010 to July 2016 and whose files were accessed. Fifty-three non-pregnant female patients of reproductive age who were operated on for appendicitis during the same period were included in the study as the control group. The patients in both groups were divided into two groups based on their AS total score being 7 and ≥ 7. RESULTS: The mean age of the 48 pregnant patients was 28 (19-42) years, while the mean age of the 53 control patients was 31 (18-45) years. Among pregnant and non-pregnant women, about a third of patients had an AS < 7 (16 of 48 versus 18 of 53). There was no significant difference when the AS scores of both groups were compared (p = 0.947). Using pathology results as reference test, the sensitivity and specificity of the AS in pregnant women was 79 and 80%. CONCLUSIONS: As a result, when the data collected by our study are evaluated, we see that pregnancy does not have a negative effect on the efficacy of AS. Therefore, the AS system can be an easy, non-invasive auxiliary diagnostic tool with high diagnosis accuracy rates that can be used in pregnant patients suspected of having acute appendicitis.

Effect of dietary supplementation of hemp seed (Cannabis sativa L.) on meat quality and egg fatty acid composition of Japanese quail (Coturnix coturnix japonica).

This study was conducted in two separate experiments. Experiment I was conducted to investigate the effects of hemp seed (HS) on meat quality traits, and experiment II was designed to determine egg fatty acid (FA) composition in Japanese quail (Coturnix coturnix japonica). In experiment I and experiment II treatments, groups were as follows: (i) control (not included HS0), (ii) 5% HS inclusion to diets, (iii) 10% HS inclusion to diets and (iv) 20% HS inclusion to diets. In experiment I, a total of 192 7-day-old-quail were fed with HS diets for 5 weeks, and end of the experiment I, a total of 64 quail (16 each) slaughtered and meat samples were analysed for meat colour, pH, cooking and thawing loss and FA composition. In experiment II, a total of 120 8-week-old laying quail were fed with experimental diets for 6 weeks and egg FA composition were determined. Breast meat cooking loss was significantly lower in 20% supplemented group (p < 0.01). Hemp seed inclusion to diets caused a linear and cubic increase in redness (a*) of hip meat (p < 0.01). Palmitoleic and oleic FAs were decreased with HS addition in breast meat (p < 0.05); however, linoleic and linolenic acid contents of meat were linearly increased (p < 0.01). In experiment II, the linoleic and linolenic FA contents of egg samples were linearly increased with increasing the dietary HS ratio (p < 0.01). Hemp seed addition was provided lower palmitoleic and oleic FAs in quail eggs (p < 0.05). In conclusion, HS supplementation to quail diets may increase quail meat redness and meat and egg yolk omega-3 FA content and decrease cooking loss of quail meats.

Oro-dental characteristics of three siblings with Papillon-Lefevre syndrome.

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder, showing oral and dermatological manifestations in the form of aggressive periodontitis, leading to the premature loss of both primary and permanent teeth at a very young age and palmar-plantar hyperkeratosis. It was first described by two French physicians, Papillon and Lefevre in 1924. Immunologic, genetic, or possible bacterial etiologies have been thought to account for etiopathogenesis of PLS. Severe gingival inflammation and periodontal destruction occurred after the eruption of primary teeth. This condition should warn the physicians and dentists as a one of the important sign for the diagnosis of PLS. There have been over 250 cases reported in literature about PLS, but a few of these were in the same family. This study presents oro-dental characteristics, dental treatments, and follow-up of three siblings (age of sisters are 13, 6, and 4 years) with PLS, which is rarely seen in the same family.

Correlation between Bethatrophin and 25(OH)D Concentrations in a Group of Subjects With Normal and Impaired Glucose Metabolism.

Aim: Inducing beta cell replication is a potential therapeutic approach for the treatment of diabetes mellitus. Recently betatrophin was suggested as a novel stimulator of beta cell proliferation in mice but its role in humans remains to be established. We aimed to investigate betatrophin concentration and its association with metabolic parameters in a group of individuals with normal glucose tolerance, pre-diabetes and diabetes mellitus who had not been previously treated. Methods: A total of 72 subjects were recruited for this cross sectional study: 23 subjects with normal glucose tolerance (NGT), 22 subjects with prediabetes, and 27 subjects with diabetes mellitus (DM). Circulating betatrophin concentration, 75 g oral glucose tolerance test, fasting insulin, glycosylated hemoglobin, 25hydroxy vitamin D and HOMA IR were measured. Results: The difference in betatrophin values did not reach statistical significance between the 3 groups [NGT:206 (176-297)pg/mL, Prediabetes:232 (181-254)pg/mL, DM:245 (205-526)pg/mL, p=0.078]. Betatrophin was negatively significantly correlated with BMI and positively significantly correlated with 25(OH)vitD (p=0.043 and p=0.001 respectively). Multivariate linear regression showed that 25(OH) vitD (ß=0.440 p=0.001) and fasting glucose (ß=0.003 p=0.038) were variables associated with betatrophin concentration (R2=0.251). Conclusions: In a group of subjects ranging from those with normal glucose tolerance to newly diagnosed diabetes, we found that 25(OH)D and fasting glucose were factors associated with serum betatrophin concentration.

Comprehensive dental management in a Hallermann-Streiff syndrome patient with unusual radiographic appearance of teeth.

Hallermann-Streiff syndrome (HSS) is a genetic disorder characterized by proportionate dwarfism, birdlike facies, hypotrichosis, skin atrophy, dyscephaly, bilateral microphthalmia, congenital cataracts, a narrow, weak, beaked nose, a hypoplastic mandible, and orodental anomalies. Occurrence is sporadic and distinct patterns of inheritance have not been found. This case report describes the dental management of a 3-year-old girl patient with HSS, who had unusual radiographic appearance of teeth. Furthermore, dental treatments and a 30-month follow-up period of the patient with this rare tooth structure malformation have been presented.

Endometrial adenocarcinoma in young-aged women: a Turkish population study.

PURPOSE OF INVESTIGATION: The present study aims to investigate the incidence, clinicopathological features, and experience of treat- ment outcomes of patients with endometrial adenocarcinoma (EC) at ≤ 40 years of age in a gynecologic oncology reference center in Ankara, Turkey. MATERIALS AND METHODS: This retrospective study included 577 patients with EC, diagnosed and treated between 2007 and 2013. RESULTS: The incidence of EC ≤ 40 years of age was 5.1% (n: 30). The mean age at diagnosis was 35.5 (range: 27-40). Most of the patients with EC were overweight or obese. However, 23% had normal body mass index (BMI). Infertility was seen as a risk factor in 38.4%. The mean duration of postoperative follow-up was 38.3 months with rates of disease persistence and recurrence 14.2% and 28.5%, respectively. CONCLUSION: The disease is diagnosed usually in its early stage and has a good prognosis. Appropriately selected patients with fertility desire have the opportunity to conceive with conservative management.

Effect of hempseed (Cannabis sativa L.) on performance, egg traits and blood biochemical parameters and antioxidant activity in laying Japanese Quail (Coturnix coturnix japonica).

1. This study was conducted to determine the effects of hempseed (HS) on performance, egg traits, serum lipid profile and antioxidant activity in Japanese quail (Coturnix coturnix japonica). 2. A total of 120 eight-week-old laying quail were divided into 4 experimental groups with 10 replicates. The treatments were as follows: (1) control diet (C, no HS in the diet); (2) 5% HS in the diet (HS5); (3) 10% HS in the diet (HS10); and (4) 20% HS in the diet (HS20). The quail were fed the experimental diets from 8 to 14 weeks of age. 3. There was no significant difference in body weight, feed intake and feed conversion ratio of the birds overall in the experiment. The egg production was not influenced by the HS contents in the diet; however the HS10 diet increased egg weight and egg-specific gravity. The carcass traits were not affected by the HS contents. 4. The serum triglyceride, cholesterol and the high density lipoprotein were not significantly altered; however, low density lipoprotein (LDL) concentration in HS-supplemented groups were lower than that of the C group. 5. The malondialdehyde, superoxide dismutase, catalase and nitrogen oxide concentrations were not significantly affected, but in the HS10 and HS20, glutathione peroxidase (GSH-Px) concentration was higher than in the C and HS5 groups. 6. The omega-3 fatty acid content of eggs increased linearly with increasing dietary HS content in the diet. 7. In conclusion, HS could be a potential feed and health benefit as a natural antioxidant in relation to decreasing serum LDL and increasing GSH-Px concentration in the liver of laying quail.

Molecular characterization and lipase profiling of the yeasts isolated from environments contaminated with petroleum.

In the present study, 120 yeast isolates from different sources (active sludge, soil, and wastewater samples obtained from petroleum refinery and soil contaminated by petroleum) were obtained. The yeast isolates were screened for lipase production and twelve of the isolates (D3, D17, D24, D27, D30, D38, D40, D42, D44, D46, D56, and D57) exhibited lipase activity. Molecular characterization of the yeasts showing the lipase production was performed with RFLP of ITS1-5.8S-ITS2 and 18S rRNA and sequence analysis of D1/D2 domain of 26S rRNA. The 26S rRNA sequencing revealed that four new strains, D38, D40, D44 and D57 identified as Rhodotorula slooffiae, Candida davisiana, Cryptococcus diffluens, and Cryptococcus uzbekistanensis, respectively, are lipase producing yeast species. This study is the first report showed lipase production by these species. The other lipase producing strains identified as Candida parapsilosis (D3), Rhodotorula muciloginosa (D17 and D42), Cryptococcus albidus (D24, D27, D30, and D56), and Wickerhamomyces anomalus (D46).

Vitamin B12 and folate deficiency: should we use a different cutoff value for hematologic disorders?

INTRODUCTION: Anemia and macrocytosis are well-defined expected hematologic findings of vitamin B12 and folate deficiency; however, some previous studies did not show a significant association of subnormal B12 with anemia and macrocytosis. METHODS: We retrospectively analyzed 17 713 laboratory patient records to evaluate vitamin B12 and folate levels in relation to anemia and macrocytosis. RESULTS: In an age- and sex-adjusted logistic regression model, low B12 status but not marginal B12 status was significantly associated with anemia [ORs respectively, 1.291 (95% CI, 1.182-1.410), 1.022 (95% CI, 0.943-1.108)] and macrocytosis [ORs, respectively, 3.853 (95% CI, 3.121-4.756), 1.031 (95% CI, 0.770-1.381)]. Also low folate status but not marginal folate status was significantly associated with anemia [adjusted ORs, respectively, 1.819 (95% CI, 1.372-2.411), 1.101 (95% CI, 0.931-1.301)] and macrocytosis [adjusted ORs, respectively, 2.945 (95% CI, 1.747-4.965), 1.228 (95% CI, 0.795-1.898)]. CONCLUSION: Our results show that increased anemia and macrocytosis are observed at values below commonly used B12 lower-reference thresholds. Determining a hematologic cutoff value may help physicians in clinical practice.

Role of omentectomy and appendectomy in surgical staging of endometrioid endometrial cancer.

PURPOSE: The purpose of this study was to determine whether it was necessary to add omentectomy and appendectomy to the surgical staging of endometrioid endometrial cancer. MATERIALS AND METHODS: Records were reviewed from June 2005 to June 2009 for endometrioid endometrial cancer patients who underwent total abdominal hysterectomy, bilateral salpingo-oophorectomy, pelvic and para-aortic lymphadenectomy, infracolic omentectomy and appendectomy. RESULTS: In total, 186 patients were included in the analysis. Disease was limited to uterus in 93% of patients and 87% of patients had Stage I disease. There was only one omental metastasis and no appendix metastasis in all stages. CONCLUSION: Routine omentectomy and appendectomy are unnecessary in surgical staging of endometrioid endometrial cancer unless there is suspicion of gross metastases during intraoperative examination.

Changes in liquid emptying in migraine patients: diagnosed with liquid phase gastric emptying scintigraphy.

Gastric stasis is suspected mostly to be encountered during acute migraine attack. The aim of this study is to evaluate the liquid phase gastric emptying and motility in migraine patients in ictal and interictal periods in comparison to normal subjects with gastric emptying scintigraphy. Seven women with migraine and age, sex matched controls who applied to the Neurology Department from May 2009 to May 2010 were compared. Gastric emptying study with a standard liquid was performed one time in the non-migraineur group and two times in the migraineur group. Non-migraineur controls and migraineurs were compared. The mean T1/2 was longer in ictal period in migraineurs. The T1/2 of migraineurs interictally and the control groups were similar. The T1/2 of migraineurs ictally and migraineurs interictally were also compared. We also considered the percentage of the radioactive material remaining in the stomach. There were no significant differences between non-migraineurs and migraineurs interictally. However, increased amount of radioactive material remaining in the stomach was observed in migraineurs ictally. We concluded that the liquid emptying was delayed in spontaneous migraine attacks in migraine without aura, however in the interictal period the emptying of liquids did not differ between migraineurs and non-migraineurs.

Anomalías en la función de la pared izquierda ventricular en pacientes con espondilitis anquilosante evaluados por gammagrafía de perfusión miocárdica sincronizada / Left ventricular wall function abnormalities in patients with ankylosing spondylitis evaluated by gated myocardial perfusion scintigraphy

Objetivo. La espondilitis anquilosante (AS) es una enfermedad inflamatoria crónica con inflamación importante en las articulaciones y los órganos extraarticulares. Los pacientes con AS tienen aproximadamente dos veces más riesgo de mortalidad que la población normal. Una de las razones de este aumento en mortalidad, es el aumento del riesgo cardiovascular. Este estudio se planificó para evaluar la perfusión miocárdica y función ventricular izquierda con 99mTc-MIBI perfusión miocárdica sincronizada computarizada por emisión de foton único (SPECT). Material y métodos. El grupo de estudio consistió en 28 pacientes con AS (19 hombres y 9 mujeres), y la edad media de 39,46±10,98 años. Todos los pacientes fueron sometidos a 99mTc-MIBI SPECT de perfusión miocárdica sincronizada con el protocolo del mismo día. Resultados. Hemos detectado varios factores de riesgo como el hábito de fumar en 12, antecedentes familiares de enfermedad cardiovascular en 12, la hipertensión arterial en 3, la hiperlipidemia en 9 pacientes. Hemos llevado a cabo la perfusión miocárdica SPECT para cada paciente, el patrón de perfusión normal siendo en las imágenes SPECT. De los 28 pacientes, ocho pacientes tuvieron una perfusión normal, pero anomalías en el movimiento de la pared. Conclusión. Hemos detectado que la perfusión miocárdica se preserva en los pacientes con AS. Sin embargo, se observa anormalias en el movimiento de la pared venticular izquierda. Llegamos a la conclusión que la espondilitis anquilosante pueda ser asociados con la disfunción microvascular y la gammagrafía de perfusión miocárdica sincronizada podría ser útil en pacientes con EA para la evaluación de la función del ventrículo izquierdo, aún si existe una baja puntuación en el índice de actividad de la enfermedad espondilitis anquilosante (BASDAI) y menor duración de la enfermedad(AU)

Background. Ankylosing spondilitis (AS) is a chronic inflammatory disease with prominent inflammation in joints and extraarticular organs. AS patients have approximately two times more risk of mortality than the normal population. One reason for this increase in mortality is increased cardiovascular risk. In this study, we have aimed to evaluate myocardial perfusion and left ventricular function using 99mTc-MIBI gated myocardial perfusion single photon emission computed tomography (SPECT). Material and methods. The study group consisted of 28 AS patients (19 men, 9 women), and mean age 39.46±10.98 years. All patients underwent 99mTc-MIBI gated myocardial perfusion SPECT with the same day protocol. Results. We detected various risk factors including smoking habits in 12, family history of cardiovascular disease in 12, hypertension in 3, hyperlipidemia in 9 patients. We performed a myocardial perfusion SPECT for each patient and found normal perfusion pattern in SPECT images. Out of 28 patients, eight patients had normal perfusion but wall motion abnormalities. Conclusion. We detected that myocardial perfusion is preserved in the patients with AS. However, left ventricular wall motion abnormalities are seen. We concluded that ankylosing spondylitis may be associated with microvascular dysfunction and gated myocardial perfusion scintigraphy could be valuable in AS patients for the evaluation of LV function even if the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score are low and the disease duration shorter(AU)

Vertical rectus abdominis myocutaneous flap for vaginal reconstruction after radical pelvic surgery for Stage II vaginal carcinoma.

Primary carcinomas of the vagina are uncommon, occurring only 2-3% of all gynecological malignancies. In women with early stage of disease, primary surgery, consisting of radical vaginectomy (plus hysterectomy in patients with tumors involving the upper vagina) and systematic dissection of lymphatic drainage of tumor, is a valid option. In these patients, a rectus abdominis myocutaneous (RAM) flap may be favorably used for vaginal reconstruction during radical pelvic surgery. Here we describe a case of Stage II vaginal carcinoma treated with radical pelvic surgery and vertical-RAM (V-RAM) flap reconstruction.
