RESUMO

AIM: While the ratio of neutrophil-to-lymphocyte (NLR) increases with inflammation, its importance in Graves' disease is not clear. The aim of this study was to evaluate NLR, a marker of chronic inflammmation, in Graves' disease. METHODS: 86 Graves' patients (37 before treatment,49 euthyroid patients after treatment) and 112 controls were enrolled. Hematologic parameters, thyroid function tests, age and gender were recorded. NLRs were calculated. Firstly, groups were composed as Graves' group (Group1) and participants without thyroid disorder as control group (Group2). Secondly, Graves' patients before treatment were considered as Group1a, euthyroid Graves' patients after antithyroid treatment were considered as Group1b. These groups were compared with each other in terms of descriptive data and hematological parameters. RESULTS: Lymphocyte, monocyte, platelet, free T3, and free T4 levels were significantly higher in Graves' group than the controls. TSH and NLR were significantly lower in Graves' group Graves' than the controls. Differences among group1a and group1b for monocyte (p = 0.013), for basophil (p= 0.002), for platelet (p = 0.029), and for NLR (p = 0.029) were statistically significant. CONCLUSION: Unlike other inflammatory diseases, in Graves' disease; hematological parameters may not give information about inflammatory state of the disease. Therefore, NLR should be evaluated with other serum inflammatory markers in Graves' disease (Tab. 2, Fig. 1, Ref. 26).

RESUMO

PURPOSE: Previous studies have demonstrated the relationship between hyperthyroidism and increased risk of cardiac arrhythmias. The most common causes of hyperthyroidism are Graves' disease (GD) and toxic nodular goiter (TNG). The aim of our study was to demonstrate if the underlying mechanism of hyperthyroidism, in other words autoimmunity, has an impact on the type of cardiac arrhythmias accompanying hyperthyroidism. METHOD: Twenty patients with TNG and 16 patients with GD who had overt hyperthyroidism were included in the study. Age, sex, thyroid hormone levels, thyroid autoantibody positivity, thyroid ultrasonography and scintigraphy results were recorded. 24-hour Holter ECG monitoring was performed in all patients. RESULTS: Mean age was significantly higher in the TNG group compared to the GD group (62.9±11.5 vs. 48.9±8.6 years, p=0.001). Free T3 was significantly higher (7.87±3.90 vs. 5.21±1.53 pg/mL, p=0.033) in the GD group while free T4 and TSH levels were similar between the two groups. In 24-hour Holter ECG recordings nonsustained ventricular tachycardia (VT) rates were significantly higher in the GD group than in TNG group [18.75% (n=3/16) vs. 0% (n=0/20), respectively, (p=0.043)]. Paroxysmal atrial fibrillation (AF) rates were significantly higher in the TNG group compared to GD group [(30% (n=6/20) vs. 0% (n=0/16), respectively, (p=0.016)]. CONCLUSION: Although free T3 levels were lower, paroxysmal AF rates were found significantly higher in the TNG group which may be associated with significantly higher age of this group. On the other hand, higher rate of nonsustained VT in the GD group may be related to either significantly higher free T3 levels or autoimmunity.

RESUMO

BACKGROUND: Depending on hyphothalamic, hyphophyseal, and gonadal axis dysfunction, anovulatory irregular cycles occur and the probability of pregnancy decreases in the patients with chronic kidney disease (CKD). Maternal mortality and morbidity rates are increased in CKD patients; the risk of premature delivery is 70% and the risk of preeclampsia is 40% more than normal among those with a creatine level of >2.5 mg/dL. METHODS: If a pregnancy is expected in the sequel of kidney transplantation (KT), a multidisciplinary team approach should be adopted and both the gynecologist and the nephrologist should follow the patient simultaneously. Among 3883 patients who underwent KT at Antalya Medical Park Hospital Transplantion Department between November 2009 and October 2016, the records of 550 female patients between the ages of 18 and 40 years were examined retrospectively; 31 patients who complied with these criteria were included in the study group. In 6 of these patients who had an unplanned pregnancy, medical abortion was performed after the families were informed about the possible fetal anomalies caused by the use of everolimus in the first trimester, and they were excluded from the study (pregnant group). The control group consisted of 43 patients who had a KT and became pregnant, and of those who had recently undergone KT and shared similarities regarding age, CKD etiology, duration of dialysis, and number of transplants. RESULTS: In both groups, the ages of the patients, their follow-up span and dialysis duration, tissue compatibility, age of the donor, and time elapsed until the pregnancy was analyzed, whereas in the control group, creatinine levels in the first, second, third, and fourth years after the KT were reviewed. Additionally, in the pregnant group, creatinine levels of the first, second, and third trimesters; delivery week; birth weight of the baby; APGAR scores of the first minute; postnatal creatinine levels of first, second, and third years; and prenatal, maternal, and postnatal acute rejections were reviewed. We measured the creatine clearance by use of the Cockcroft-Gault formula in the pregnancy group before pregnancy and during delivery [Cockcroft-Gault formula: (140 - age) × body weight (kg)/72 × plasma creatine level (mg/dL) × 0.85]. CONCLUSIONS: Pregnancy after KT is risky both for the mother and the baby; however, if planned and followed in coordination within an experienced center, both the pregnancy period and the birth process can occur without distress.

RESUMO

PURPOSE: To compare a minimally invasive preperitoneal (MIP) single-layer mesh repair with the standard Lichtenstein hernia repair (LHR) for inguinal hernia in terms of operative characteristics, recovery, complications, recurrence and chronic pain. METHOD: Two hundred and twenty male patients diagnosed with primary inguinal hernia were randomized to either MIP or LHR methods. MIP repair consisted of a single-layer polypropylene mesh developed by our group placed preperitoneally using the Kugel technique. Patients were followed for a minimum of 2 years. Chronic pain was assessed by Sheffield's pain score. RESULTS: One hundred and one patients in MIP group and 105 patients in LHR group were included in the analysis. Most patients were diagnosed with indirect hernia (n = 79 for MIP, n = 81 for LHR). Surgery was slightly but significantly shorter for MIP (38.2 ± 7.4 vs. 40.3 ± 6.6, p = 0.031). Early complications such as cord edema, hematoma, scrotal edema, and wound infection were infrequent in both groups. Recurrence was detected in three patients in MIP and one patient in LHR. Chronic pain score was similar with both methods within the first year, but significantly lower for MIP at 24 months (0.66 ± 0.06 vs. 0.87 ± 0.07, p = 0.03). CONCLUSION: MIP single-layer mesh repair is as effective and safe as LHR, with the additional benefits of minimally invasive nature, less chronic pain at 2 years and low polypropylene load when compared with the original Kugel patch.

RESUMO

BACKGROUND/OBJECTIVE: Reflectance confocal microscopy (RCM) is a noninvasive, objective imaging technique that provides in vivo, high-resolution skin imaging. We sought to assess epidermal and dermal changes associated with the psoriasis and its treatment with RCM before the treatment and at weeks 4 and 8 of the treatment. MATERIAL AND METHODS: This is an investigator-blinded, internal-controlled, follow-up study. A total of 25 patients with plaque psoriasis were included in the study. The RCM evaluation criteria were defined on the basis of the histopathological diagnostic criteria for psoriasis. The clinical severity of the psoriasis was evaluated using the Psoriasis Area Severity Index (PASI). RESULTS: The RCM findings which were correlated with the PASI can be used to follow up the patient's response to treatment have been identified as follows: the acanthosis, the number of spongiotic sites, the number of regular/irregular honeycomb-like sites, the number of epidermal inflammatory cells, the number of focal microabscesses, the total epidermal thickness, the number of nonedge dermal papillae, the length of the papillary dermis, the number of dermal inflammatory cells, and the vascularization in the papillary dermis (P < 0.05). CONCLUSION: This is the first study with a large group of patients to perform a noninvasive assessment with RCM of the response of psoriasis to different treatments: phototherapy, systemic and topical treatment. Micrometric and morphometric changes occurring in the psoriatic tissue during the 8-week treatment period were identified by in vivo RCM in a noninvasive manner. RCM is capable of monitoring of treatment response in psoriasis.

RESUMO

BACKGROUND: Although many methods, either surgical or non-surgical, are being used for the treatment of pilonidal sinus disease (PSD), there is still no consensus as to what constitutes the most appropriate method of treatment. The aim of this study was to compare the outcomes of the Limberg flap (LF), modified Limberg flap (MLF), and Karydakis flap (KF) procedures. METHODS: A prospective, randomized study was conducted on 295 patients scheduled for surgical treatment for PSD at the General Surgery Clinic of the Konya Training and Research Hospital in January 2009-May 2010. Patients with recurrent disease, an ASA score higher than III, obesity (BMI > 35 kg/m(2)), insulin-dependent diabetes, or a drug or alcohol addiction were excluded. The procedures performed were as follows: LF (n = 96), MLF (n = 108), and KF (n = 91). RESULTS: The patients were followed up for a median of 33 months (range 24-41 months). There were more female patients in the LF group. The rate of seroma formation was higher in the KF group (19.8 %) compared to the LF and MLF groups (5.2 and 7.4 %, respectively; p = 0.027). The rate of wound dehiscence was higher in the KF group (15.4 %) compared to the LF and MLF groups (2.1 and 3.7 %, respectively; p < 0.001) as was the incidence of flap maceration (11 % in the KF vs. 1 % in the LF and 3.7 % in the MLF; p = 0.004). The incidence of PSD recurrence was also higher in the KF group (11 %) compared to the LF and MLF groups (6.3 and 1.9 % respectively; p = 0.027). In a multivariate analysis, the presence of seroma, hematoma, and wound infection were independent predictors of recurrence. CONCLUSIONS: In our study, LF and MLF procedures were associated with a lower recurrence and complication rate compared to KF. However, more randomized studies comparing different reconstruction methods after PSD excision are needed.

RESUMO

BACKGROUND: Increased reactive oxygen species (ROS) and lipid peroxidation are seen in many dermatologic disorders, including atopic dermatitis, psoriasis, vitiligo, acne vulgaris, pemphigus vulgaris (PV), lichen planus and alopecia areata. In PV, the increased production of ROS from activated neutrophils reduces the concentrations of antioxidant vitamins and enzymes. OBJECTIVE: The present study aims to determine the oxidative stress index (OSI) by studying serum total oxidant capacity (TOC), lipid hydroperoxide (LOOH) and total antioxidant capacity (TAC) in PV patients. METHODS: The study included 27 PV patients and a control group consisting of 24 healthy volunteers. Serum TOC, LOOH and TAC levels were examined and OSI was measured in the PV patients and the control group. RESULTS: TOC (P = 0.001) and LOOH (P = 0.001) levels as well as OSI (P = 0.001) were found higher in the PV patients, relative to the control group. Serum TAS (P = 0.221) did not differ between groups. Serum TOC, LOOH and TAC levels and OSI in PV patients with mucosal involvement were not different than those in mucocutaneous PV patients. CONCLUSION: Serum TOC and LOOH levels and OSI were higher in the PV patients, in comparison with the control group. Serum TAC level was not different.

RESUMO

BACKGROUND: Chronic anal fissure is diagnosed in the presence of persistent symptoms: The classic triad includes a linear mucosal tear exposing the internal sphincter fibers, hypertrophied anal papilla, and a sentinel skin tag. Thus, chronic anal fissure can be divided into three components: the fissure itself; hypertrophied anal papilla; the sentinel skin tag. Not every chronic anal fissure has all three components; some have two components, and others present with only a persistent fissure. The success rate of medical treatment for chronic anal fissure is reported as 42-86 %. In this study, we intended to observe the effect of said components on healing with isosorbide dinitrate treatment. METHODS: A total of 105 patients with chronic anal fissures were admitted and were divided into three groups. Patients in group I had a single component (only the fissure with a linear mucosal tear exposing the internal sphincter fibers); group II had two components (skin tag or hypertrophied papilla in addition to the fissure); group III had all three components (fissure, skin tag, hypertrophied papilla). Isosorbide dinitrate 0.25 % was applied three times a day. RESULTS: The success rates in the study groups were 93, 74, and 64 %, respectively. The success rate was significantly higher for group I than for groups II and III. CONCLUSIONS: Chronic anal fissure components should be considered when evaluating the success rates of studies reporting the results of various medical treatments. The number of components seems to be an important factor that affects the results of isosorbide dinitrate treatment.

RESUMO

BACKGROUND: Toll-like receptor (TLR) polymorphisms have been associated with atopic diseases in children and adults. Development of atopic diseases may be modified by TLR-mediated signals that modulate T-regulatory cells (Tregs) early in life when maternal influences are still present and relevant. The aim of this study was to assess whether genetic TLR variants influence Tregs in neonates. METHODS: Twelve single nucleotide polymorphisms located in TLR1, TLR2, TLR4, TLR6, and TLR10 were genotyped in 200 cord blood samples (72 samples from atopic, 128 from nonatopic mothers). Cord blood mononuclear cells were cultured without or with stimulation [lipid A (LpA), peptidoglycan (Ppg), phytohemagglutinin, house dust mite]. mRNA expression of Treg marker genes [forkhead box protein P3 (FOXP3), glucocorticoid-induced tumor necrosis factor receptor (GITR), lymphocyte activation gene 3 (LAG3)], TLR2, Th1/Th2 cytokines, and tumor necrosis factor alpha (TNF-α) was measured. RESULTS: In children with the AA genotype of the TLR2 promoter variant rs4696480, gene expression of FOXP3 and Treg marker genes GITR and LAG3 as well as Th2 cytokines and TNF-α secretion was significantly increased in the presence of maternal atopy and Tregs decreased without maternal atopy. In carriers of the GG genotype for TLR2 rs1898830, gene expression of Treg marker genes was significantly decreased with and increased without maternal atopy. FOXP3 expression was also modified by TLR1 rs4833095 (P ≤ 0.03) and trendwise by TLR10 rs4129009 after LpA and Ppg stimulation. CONCLUSIONS: Genetic variations of TLR2, TLR1, and TLR10 affect Treg marker gene expression in cord blood. Gene-immunological interactions of the TLR pathway influence Tregs early in life, modulated by maternal atopy. This may be relevant for immune maturation in the development of atopic diseases in childhood.

RESUMO

The intent of the study was to clarify the technique and the application of the electrophysiological bulbocavernosus reflex (EBCR) test in healthy female dogs. For this aim, 15 healthy female dogs were used in the study. The stimulations were made on the clitoris and the responses were recorded from the right side of the external anal sphincter muscle with a concentric needle recording electrode. The EBCR had response latencies between 18.99 and 25.69ms with the mean value of 22.26ms. The EBCR reflex test is not yet widely used for the evaluation of the functional integrity of sacral spinal cord segments and nerve roots in veterinary clinics. Our experiences indicated that the EBCR reflex test gives valuable data about sacral spinal reflex arc functionality and can be accepted as a routine diagnostic method in small animal clinics for evaluation of the sacral reflex arc.

RESUMO

This study has been carried out to determine the effect of neutral position, hyperextension and hyperflexion of the tarsal joint on the tibial nerve, motor action potential latency and tarsal canal compartment pressure in dogs with the aid of electrophysiological and anatomical methods. Totally twenty healthy mongrel dogs were used. Latency of motor nerve action potential (MNAPL) studies of tibial nerve via surface stimulating and needle recording electrodes was performed on right hind limbs of all the dogs. The compartment pressures of the tarsal canal with the pressure transducer were determined from both limbs from ten of the dogs. In one dog, tarsal regions of both left and right limbs were demonstrated using magnetic resonance imaging (MRI). Two dogs were euthanatized and tarsal regions of the dogs were sectioned for correlative anatomy. Nerve conduction studies showed that the MNAP latency of the tibial nerve were 3.55 +/- 0.097 ms, 3.76 +/- 0.087 ms and 3.39 +/- 0.097 ms in neutral, hyperextension and hyperflexion positions, respectively. Hyperflexion of the tarsal joint caused prolongation of the MNAP latency of the tibial nerve with the highest pressure value being determined in tarsal canal. From the anatomical viewpoint, the distance between the flexor hallucis longus muscle and the superficial digital muscle was the shortest during hyperflexion and the plantar branch of saphenous artery, lateral and medial plantar nerves located more laterally in cadaver and MR imaging sections. As a result of this study, it is thought that tarsal region diseases as well as long time splint in the hyperflexion position as applied in the Ehmer sling can affect the compartment pressure and nerve tension because of occupying in the tarsal canal. Raising pressure and nerve stretching in the tarsal canal compartment could cause deficiencies in the conduction velocity of the tibial nerve. This might be a result of tarsal tunnel syndrome in the dog. Clinicians could consider this syndrome in cases of tarsal region diseases as well as application of long time splint in hyperflexion of tarsal joints in dogs.

RESUMO

The electrophysiological bulbocavernosus reflex test consists of recording the electromyographic activity of the bulbocavernosus muscle following electrical stimulation of the glans penis. This study has been carried out to show the applicability of the electrophysiologic bulbocavernosus reflex (EBCR) in dogs and to determine its normal latency value. Ten healthy male dogs were used. Responses to stimulation of the bulbus glandis were recorded from the left bulbocavernosus muscle with a concentric needle-recording electrode. In 10 dogs of maximum size 31 kg and maximum age 3 years, EBCR had response latencies between 17.6 and 28.8 ms with the mean value of 24.4 ms. The results of this study show that the electrophysiological bulbocavernosus reflex test could be employed as a routine diagnostic method in small animal clinics for evaluation of the sacral reflex arc. Among several advantages are easy applicability and the objective result, with the latency exceeding 29 ms not being seen in the dogs used in our study.

RESUMO

Linear measurements were made by computed tomography of the diameter of the femoral head, the width and depth of the acetabulum and the dorsal and ventral acetabular rim distances in 10 healthy German shepherd dogs, and angular measurements were made of the axial acetabular index, acetabular anteversion, and the dorsal and ventral centre-edge angles. There were no significant differences between the measurements made on the left and right sides. The width of the acetabulum was about twice its depth, and was a little larger than the diameter of the femoral head. The mean values of the axial acetabular index, acetabular anteversion, and ventral and dorsal centre-edge angles were 100.9 degrees, 25.1 degrees, 48.0 degrees and 12.2 degrees, respectively.

RESUMO

Computed tomographic images of the thoracic spine of 13 German shepherd dogs were examined in order to determine the thoracic spine morphometry. Examinations were carried out in the transverse plane both intervertebral and mid-vertebral levels of the each thoracic vertebrae. The dorsoventral and interpedicular diameters of the spinal canal, the dorsoventral and transverse diameters of the vertebral body, the dorsoventral and transverse diameters of the spinal cord and also the cross-section area of the spinal canal were measured. The maximum values were found to be at the level of C7-T1. The shapes of the spinal canal and cord were circular in middle part, the shape became transverse oval in the cranial and caudal parts of the thoracic spine. The most significant correlation between the diameters was found to be in male dogs, except between dorsoventral diameters of the spinal canal and that of the vertebral body and between dorsoventral diameters of the spinal canal and transverse diameters of the vertebral body.

RESUMO

Pelvimetry was performed on a computed tomographic scanner using dorsal and lateral scout-view images of 10 adult German shepherd dogs. The vertical and transverse diameters of the pelvis were measured and the pelvic inlet and pelvic outlet areas were also calculated. No significant correlations between the pelvic measurements and body weight, age and sex were found. Although the conjugata vera, diameter verticalis, diameter sacralis, sagittal diameter and the distance between the two medial tubera ischiadica were longer in females, no significant statistical difference was found between male and female animals for all measurements. It is proposed that the computed tomographic pelvimetry should be preferred for the sensitive measurements when the normal standards are determined for different animal species and the cost is reduced to an acceptable level.

RESUMO

In order to determine what should be done for laryngeal cancer patients when surgical margins are positive, and to evaluate their prognosis, a retrospective review of 21 laryngeal cancer patients with positive surgical margins out of 714 surgically treated cases (2.9%) was carried out. Nineteen patients were treated with postoperative radiation therapy. Two patients who had had endolaryngeal partial laryngectomy were treated with vertical partial laryngectomy. Two patients were lost to follow-up. Ten patients (10/19; 53%) were recurrence-free. Four patients had local, two had regional, and two had locoregional recurrences. Only one patient with a local recurrence could be salvaged with total laryngectomy and is disease-free. One patient developed liver metastasis. Nineteen patients had a mean and median disease-free survival of 48 and 36 months, respectively. Nine out of fourteen patients (64%) treated curatively were recurrence-free. The patients with positive margins developed significantly more locoregional recurrences than those with free margins (P < 0.05). We conclude that surgical margins must be checked peroperatively with frozen sections to make sure that they are free. The margins of every laryngectomy specimen must be diligently examined. If positive, re-excision, postoperative radiotherapy and chemotherapy are treatment alternatives. They should not just be managed with close follow-up. However, whatever treatment is applied, the prognosis for patients with positive margins is significantly worse than for those with free margins.

RESUMO

This prospective randomized study investigates the possible toxic effects of interferon (IFN) alpha2A on the mouse cochlea. Thirty-six albino Swiss mice that were randomly assigned to 3 groups underwent baseline auditory brain stem response testing bilaterally to objectively assess baseline hearing levels. The first group received a single dose of 50,000 units, and the second group received 100,000 units of IFN-alpha2A intraperitoneally, whereas the third group was given no medication. Repeat auditory brain stem response testing revealed a significant rise in mean baseline peak equivalent sound pressure level thresholds in the groups that received IFN (P < 0.001). Histologically, the cochleae of mice that received IFN had a decreased number of fibroblasts in the spiral limbus, as well as prominent cytoplasmic vacuolation of these cells, compared with control animals. Loss of hair cells was not observed. It is possible that reversible biochemical and metabolic changes in the cochlea, rather than morphologic abnormalities, manifest IFN ototoxicity.

RESUMO

We investigated the effect of amitriptyline, a tricyclic antidepressant, on patients with subjective tinnitus. The study group consisted of 37 adult patients admitted to the Ear, Nose, and Throat and Audiology Department of Hacettepe University. The amitriptyline group consisted of 20 patients and the placebo group consisted of 17 patients. All of the patients were evaluated using a questionnaire, audiologic evaluation, high-frequency audiometry, impedancemetric tests, auditory brainstem response, tinnitus frequency, and loudness matching assessed by audiometric methods at the beginning and end of the study. The patients in the amitriptyline group received 50 mg/day amitriptyline in the first week and 100 mg/day for the following 5 weeks. In the placebo group, the patients received tablets consisting of lactose starch for 6 weeks, with a dosage of 1 tablet/day. The subjective complaints of the patients in the amitriptyline group decreased, and the "present" symptoms resulted in fewer complaints. The severity of tinnitus decreased in the amitriptyline group by means of subjective and audiometric methods. In the placebo group, no significant change was observed. The success of treatment was 95% in the amitriptyline group and 12% in the placebo group. Amitriptyline therapy was concluded to be effective.
