RESUMEN

With the increase in the number of individuals participating in sports, anterior cruciate ligament (ACL) injuries are also increasing gradually and the number of patients requiring surgical treatment is increasing in parallel. The primary aim of this study was to investigate the relationship between the need for revision surgery and graft diameter following primary ACL reconstruction (ACLR) using hamstring autografts. The secondary aim of the study was to clarify relationships between anthropometric characteristics and graft diameter. Patients who underwent ACLR with hamstring autografts were included in this retrospective study. The age, body mass index, height, and weight of all patients were recorded preoperatively and the diameters of the grafts were recorded during surgery. The relationship between revision rate and graft diameter and the relationships between anthropometric measurements and graft diameter were investigated for these patients at least one year after surgery. This study included 58 people with graft diameters of ≤7 mm and 261 people with graft diameters of >7 mm. A statistically significant difference was found between the graft diameters of the group that needed revision surgery and the group that did not (p<0.001). A positive relationship was also found between the patient's height and graft diameter (r=0.168). In this study, it was found that the risk of ACL revision surgery increased by 5.5 times among patients with graft diameters of ≤7 mm. The positive relationship between the patient's height and graft diameter can make a significant difference in terms of the need for revision surgery.

RESUMEN

The aim of the study was to examine the genotype-allele determination of CYP1A2 rs2069514 and rs762551 polymorphisms in patients with mild and severe COVID-19 and to determine their effectiveness as prognostic criteria in COVID-19. The study consists of 60 patients who were hospitalized in intensive care or outpatient treatment due to COVID-19 in Istanbul NP Brain Hospital between 2020-2021. Genotyping was conducted by Real-Time PCR. Age (p<0.001); chronic disease (p=0.002); cardiovascular disease (p=0.004); respiratory distress (p<0.001); neurological disease (p=0.004); fatigue (p=0.048); loss of taste and smell (p=0.003); nausea/vomiting (p=0.026); intubated (p<0.001); ground glass image (p<0.001) and CYP1A2 genotypes (p<0.001) showed a statistically significant difference between patients with and without intensive care admission. According to multivariate logistic regression analysis, CYP1A2 *1A/*1C + *1C/*1C genotypes (OR:5.23 95% CI: 1.22-22.36; p=0.025), chronic disease (OR:4.68 95% CI:1.14-19.15; p=0.032) or patients at 65 years or older (OR:5.17, 95%CI:1.26-21.14; p=0.022) increased the risk of admission to the intensive care unit. According to our results, we strongly suggest considering the CYP1A2 rs2069514 and rs762551 polymorphisms as important predictors of Intensive Care Unit admission in patients with COVID-19, and we also suggest that genotype results will guide clinicians for the benefit and the efficiency of the treatment.

RESUMEN

PURPOSE: To evaluate the effect of alpha-blocker treatment prior to transrectal ultrasound-guided prostate biopsy (TRUS-Bx) on voiding functions, pain scores and health-related quality-of-life outcomes. MATERIALS AND METHODS: From January 2018 to April 2019, a total of 112 patients underwent TRUS-Bx due to elevated prostate-specific antigen (PSA) or abnormal digital rectal examination findings. Patients were divided into 2 groups depending on whether they received pharmacological treatment before biopsy. Group 1 consisted of patients with no alpha-blocker treatment prior to biopsy and Group 2 consisted of patients who received Tamsulosin for one week before biopsy continuing for one week after biopsy. Voiding function was evaluated three times using the validated International Prostate Symptom Score (IPSS) and uroflowmetry (maximal flow rate (Qmax) and residual volume (PVR)). The Turkish version of the Medical Outcomes Study Short Form 36-item Questionnaire (SF-36) was used to assess health-related quality of life. Pain scores were rated according to the Visual Analogue Scale (VAS) just after the biopsy procedure. RESULTS: Mean IPSS and Qmax on the post-biopsy 7 day were significantly in favor of Group 2 (P<0.001, P=0.004). Although post-biopsy day 7 PVR was similar between the groups, Δ1 PVR was significantly in favor of Group 2 (P=0.004). Mean VAS score was 2.7±2.3 for the Tamsulosin group and 4.2±2.2 for the control group (P=0.001). There was no significant difference between two groups according to baseline and postoperative 1st month SF-36 scores. CONCLUSION: Alpha-blocker therapy prior to TRUS-Bx is effective in preventing voiding dysfunction and biopsy-related pain in patients undergoing TRUS-Bx. LEVEL OF EVIDENCE: 2.

RESUMEN

We investigated the effects of a 900 Megahertz (MHz) electromagnetic field (EMF), applied during the prenatal period, on the spleen and thymus of 21-day-old male rat pups. Pregnant Sprague-Dawley rats were divided into control and EMF groups. We applied 900 MHz EMF for 1 h/day to the EMF group of pregnant rats. Newborn male rat pups were removed from their mothers and sacrificed on postnatal day 21. Spleen and thymus tissues were excised and examined. Compared to the control group, thymus tissue malondialdehyde levels were significantly higher in the group exposed to EMF, while glutathione levels were significantly decreased. Increased malondialdehyde and glutathione levels were observed in splenic tissue of rats exposed to EMF, while a significant decrease occurred in superoxide dismutase values compared to controls. Transmission electron microscopy showed pathological changes in cell morphology in the thymic and splenic tissues of newborn rats exposed to EMF. Exposure to 900 MHz EMF during the prenatal period can cause pathological and biochemical changes that may compromise the development of the male rat thymus and spleen.

RESUMEN

UNLABELLED: This study aimed to isolate and identify the causal organism causing hyperplastic outgrowths (knots) on stems and branches of pomegranate trees in the Eastern Mediterranean region of Turkey. Bacterial colonies were isolated from young knots on plates containing selective nutrient media. Biochemical tests, fatty acid analysis and PCR were performed to identify possible causal disease agent. Representative isolates were identified as Pseudomonas.pv.savastanoi (Psv) using biochemical tests, fatty acid profiling and PCR. Following inoculation of pomegranate plants (cv. hicaz) with bacterial suspensions, 25 of 54 bacterial isolates caused typical knots at the site of inoculation. PCR analysis, using specific primer for Psv, generated a single amplicon from all isolates. The similarity of the sequence of Turkish pomegranate isolate was 99% similar to the corresponding gene sequences of Psv in the databases. Based on symptoms, biochemical, molecular, pathogenicity tests and sequence analyses, the disease agent of knots observed on the pomegranate trees is Psv. To the best of our knowledge, this research has revealed pomegranate as a natural host of Psv, which extends the list of host plant species affected by the pathogen in the world and Turkey. SIGNIFICANCE AND IMPACT OF THE STUDY: Pomegranate trees were affected by the disease with outgrowths (galls or knot) disease. Currently, there is no published study on disease agent(s) causing the galls or knots on pomegranate trees in worldwide. Bacterial colonies were isolated from young knots. The causal agent of the knot Pseudomonas savastanoi pv.savastanoi (Psv) was identified based on symptoms, biochemical, molecular methods, pathogenicity tests and sequence analysis. To the best of our knowledge, this is the first report of Psv on pomegranate as a natural host, which extends the growing list of plant species affected by this bacterium in the world and Turkey.

RESUMEN

The aim of this study was to compare the patella bone volume of sedentary men with that of elite male sportspeople, including judoka, cyclists, weightlifters, and taekwondo athletes who were members of Turkish National Professional Teams. All subjects had no history or clinical signs of an orthopaedic disorder such as osteoarthritis or acromegaly. The right and left knees of all groups were placed side by side in a supine position and were scanned by high resolution imaging with multidetector computed tomography. The differences between the volume of right and left patellae of sedentary men, judoka, cyclists, weightlifters, and taekwondo athletes were statistically significant. The average left patella of a professional cyclist and the average right patella volume of a sedentary man were maximum and minimum, respectively. The results demonstrated that the patella volume of cyclists was significantly larger. According to the literature, patella bone volume was associated with a reduced rate of annual patella cartilage volume loss, so cycling early in life may prevent patella cartilage loss in the future.

El objetivo de este estudio fue comparar el volumen de la patela en hombres sedentarios con la patela de deportistas de elite, incluyendo judokas, ciclistas, levantadores de pesas y atletas de taekwondo, miembros de equipos profesionales nacionales turcos. Los sujetos del estudio no tenían antecedentes o signos clínicos de una enfermedad ortopédica como la osteoartritis. Las rodillas derecha e izquierda de los individuos de todos los grupos se colocaron una al lado de otra, en posición supina y fueron escaneadas por tomografía computarizada multidetector de alta resolución. Las diferencias entre el volumen de la patela derecha e izquierda de los hombres sedentarios, atletas judokas, ciclistas, levantadores de pesas y atletas de taekwondo fueron estadísticamente significativas. El volumen promedio de la patela izquierda de un ciclista profesional y el volumen promedio de la patela derecha de un hombre sedentario fueron de máximo y mínimo, respectivamente. Los resultados demostraron que el volumen de la patela de ciclistas fue significativamente mayor. De acuerdo a la literatura, el volumen del hueso de la patela fue asociado con una pérdida anual de volumen del cartílago, razón por la cual el ciclismo en una edad temprana puede prevenir la pérdida de cartílago de la patela en el futuro.

RESUMEN

Pomegranate (Punica granatum L.) is an increasingly important fruit crop that is widely cultivated in Turkey. Typical bacterial blight symptoms were observed since spring of 2011 in pomegranate orchards located in Antalya Province. Symptoms were characterized by dark brown, angular to irregularly shaped spots on leaves and fruit; cankers on stems, branches, and trunks; and split trunks. The pathogen was isolated from leaf spots on naturally infected plants showing typical symptoms onto yeast dextrose chalk agar. Bright yellow bacterial colonies were consistently isolated. Bacterial strains were characterized as gram negative, oxidase negative, catalase positive, tobacco hypersensitivity positive, and able to produce acid from L-arabinose, D-galactose, D-glucose, and D-mannitol but not from D-xylose. Pathogenicity of the representative bacterial strain Serik-4 was performed on 2-year-old pomegranate plants cv. Hicaz. Leaves were sprayed until runoff with bacterial cell suspensions containing 107 CFU/ml. Inoculated plants were covered with transparent plastic bags to maintain moisture for 48 h. Negative control plants were inoculated with sterile distilled water. Plants were then incubated in a greenhouse at 30°C for 14 days. Symptoms on leaves included dark brown, angular to irregularly shaped water soaked lesions along the veins of the inoculated plants 10 days after inoculation. No lesions developed on the control plants. The symptoms on inoculated plants were similar to those on naturally infected plants. Yellow bacterial colonies were re-isolated from the inoculated plants and identified as the same as the original strain by conventional tests and FAME analysis, thus fulfilling Koch's postulates. Fatty acid methyl ester profiling of the representative strain Serik-4 using GC-MIDI (Microbial Identification Inc, Newark, DE) identified the genus of the bacterium as Xanthomonas. The identity of Serik-4 was further confirmed by amplifying the 16S rRNA gene with the universal primers 27F and 1492R (3) and sequence analysis (GenBank Accession No. KM007073). The 16S rRNA gene sequences of Serik-4 was 99% identical to the corresponding gene sequences of the Xanthomonas axonopodis pv. punicae strain present in the NCBI database (JQ067629.1). High incidence of bacterial blight caused by X. axonopodis pv. punicae on pomegranate has been previously reported in India (2), Pakistan (1), and South Africa (4). To our knowledge, this is the first report of bacterial blight on pomegranate caused by X. axonopodis pv. punicae in Turkey. References: (1) M. A. Akhtar and M. H. R. Bhatti. Pakistan J. Agric.

RESUMEN

AIM: Our aim is to introduce the cavernous artery ondulation index (CA-OI) as a new parameter that could be accepted as an indirect indicator of vascular hemodynamics and also gives us information about the efficiency of erection. PATIENTS AND METHODS: A total of 27 patients with erectile dysfunction were evaluated with penile Doppler ultrasonography (PDUS). After injection of papaverine intracavernously, arterial diameter and peak-systolic and end-diastolic velocities were measured. For measuring at a standart time, five minutes after injection, bilateral cavernosal arteries were examined and gray scale and color Doppler US images through the long axis were recorded at the mentioned phases. Cavernosal artery ondulation index (CA-OI) showing the amount of ondulation was calculated for each subject using these images. RESULTS: In 9 of total 27 patients, erection could not pass the tumescence phase with 3 flaccid phases, while the remaining 18 had full erection. Mean CA-OI values were measured as 2.51±0.37 mm, 3.15±0.38 mm, and 2.68±0.09 mm in normal, arterial insufficiency and venous insufficiency groups, respectively. CONCLUSIONS: It is possible to differentiate the arterial insufficiency by using the cut-off value of CA-OI ≥ 2.5 values as a criteria.

RESUMEN

AIM: To determine the effectiveness of transdermal electromotive administration (TEA) of verapamil and dexamethasone in the treatment of Peyronie's disease (PD). METHOD: Totally, 51 patients with PD were prospectively included in the study. All patients were evaluated by history, subjective score scales, physical examination, photographs, and penile USG, before and after therapy. All patients were treated with TEA of the combination of verapamil and dexamethasone. The treatment plan included a total of 20 sessions (at 3-day intervals for a period of 2 months), each with a duration of 20 min. At the end of the study, improvements in penile plaques, penile deviation, pain on erection, and erectile dysfunction were determined. RESULTS: The findings in 41 of the 51 patients were eligible to present. Median patient age was 52 years. Median duration of disease at presentation was 8 months. Remarkable reduction in palpable plaques and in penile angulation was observed in 10 patients (24%) and 11 (26%) patients, respectively. There were significant decreases in median plaque volume from 72 mm(2) to 45 mm(2) (P < 0.001), and in median penile angulation from 25 degrees to 15 degrees (P < 0.001). Impaired sexual activity and pain on erection had completely resolved in 11 (55%) patients and in 16 (80%), respectively. CONCLUSION: The results of our study have shown that TEA of the combination of verapamil and dexamethasone is a more effective therapy for improving subjective symptoms rather than objective symptoms. Therefore, we think that this treatment can be individualized according to the clinical features of PD patients.

RESUMEN

AIM: To study different developmental profiles and auditory perception in a representative group of children with language impairment (LI). METHODS: A multidisciplinary investigation was carried out in a group of 25 children attending units specifically for language-impaired children. An assessment of the cognitive level, motor performance, behaviour and auditory perception was performed and the results were compared with those for age-matched groups of children. RESULTS: Among those with moderate or severe language impairment (LI), around 90% had additional developmental disorders. In three tests of auditory perception, children with LI had problems with working memory and speech discrimination. No problems were found with the children's temporal resolution in auditory perception. Another conclusion from the auditory perceptual tests was that the children's cognitive abilities were important for their success in these tests. CONCLUSION: Neurodevelopmental deviations are very common in LI children. The optimal route for the assessment and treatment of these children would be a multidisciplinary approach.

RESUMEN

Prostatic biopsy is a definitive diagnostic method that should be used whenever a prostatic malignancy is suspected. Anatomically it can be done from the transrectal or perineal route. In two methods transrectal ultrasonography can be used as a helper tool. In this paper we present two cases of pelvic haematoma following prostatic biopsy that occasionally cause complications.
