The authors' aim was to investigate whether serum neutrophil to lymphocyte ratio might be used as a predictive biomarker to help differentiate active from inactive chronic otitis media (COM).
Two ...hundred fifty-nine patients having inactive COM received tympanoplasty without mastoidectomy and were identified as Group 1. On the other hand, 254 patients having active COM received tympanoplasty with mastoidectomy and were identified as Group 2. Routine hemogram tests were performed preoperatively for both the groups. By performing a chart review, white blood cell count, red blood cell count, hemoglobin, hematocrit, platelet, and mean platelet volume values were compared between the groups in an age-matched and sex-matched manner.
A total of 513 COM patients with age range of 7 to 65 years were included in the study. Two hundred seventy-five patients (53.6%) were male, 238 were (46.4%) female. Preoperatively both serum neutrophil and lymphocyte counts were significantly higher in Group 2 (P = 0.015 and P = 0.004, respectively). However, the neutrophil-to-lymphocyte ratios between the groups were not significantly different (P = 0.511).
No statistically significant differences were identified from preoperative neutrophil-to-lymphocyte ratios between patients having active COM and inactive COM.

Group A rotaviruses are the most common causative agent of acute gastroenteritis among children less than 5 years of age throughout the world. This sentinel surveillance study was aimed to obtain ...baseline data on the rotavirus G and P genotypes across Turkey before the introduction of a universal rotavirus vaccination program.
Rotavirus antigen-positive samples were collected from 2102 children less than 5 years of age who attended hospitals participating in the Turkish Rotavirus Surveillance Network. Rotavirus antigen was detected in the laboratories of participating hospitals by commercial serological tests such as latex agglutination, immunochromatographic test or enzyme immunoassay. Rotavirus G and P genotypes were determined by reverse transcription polymerase chain reaction (RT-PCR) using consensus primers detecting the VP7 and VP4 genes, followed by semi-nested type-specific multiplex PCR.
RT-PCR found rotavirus RNA in 1644 (78.2%) of the samples tested. The highest rate of rotavirus positivity (38.7%) was observed among children in the 13 to 24 month age group, followed by children in the age group of 25 to 36 months (28.3%). A total of eight different G types, six different P types, and 42 different G-P combinations were obtained. Four common G types (G1, G2, G3, and G9) and two common P types (P8 and P4) accounted for 95.1% and 98.8% of the strains, respectively. G9P8 was the most common G/P combination found in 40.5% of the strains followed by G1P8 (21.6%), G2P8 (9.3%), G2P4 (6.5%), G3P8 (3.5%), and finally, G4P8 (3.4%). These six common genotypes included 83.7% of the strains tested in this study. The rate of uncommon genotypes was 14%.
The majority of the strains analyzed belonged to the G1-G4 and G9 genotypes, suggesting high coverage of current rotavirus vaccines. This study also demonstrates a dramatic increase in G9 genotype across the country.

Pulmonary alveolar echinococcosis (PAE) is a chronic disease caused by Echinococcus multilocularis with very low incidence in developed countries.
This single-center, retrospective ...study included 34 patients who were diagnosed with PAE between January 2001 and February 2019 (15 males, 19 females, mean age: 52.4±15.8 years, age range: 28–78 years) in Ataturk University Medical School, Erzurum, Turkey.
The liver was the primary involved organ in all cases. Pulmonary involvement was detected in 13.0% (34/261) of all cases with hepatic alveolar echinococcosis (AE), and three patients (8.8%) had both pulmonary metastasis and brain metastasis. The route of spread to the lungs based on radiological data was hematogeneous in 25 patients (73.5%), transdiaphragmatic in three patients (8.8%) and both hematogeneous and transdiaphragmatic in six patients (17.7%). AE showed bilateral involvement in 19 patients (55.9%), whereas only the right lung was involved in 12 patients (35.3%) and the left lung in three patients (8.8%). Of the patients, five underwent surgery due to PAE and 29 patients received medical therapy with albendazole. A total of three patients died during the follow-up period (2, 5 and 10 years after the diagnosis of PAE), while 31 patients continued with follow-up and treatment for a mean duration of 5.4±3.8 years (1–14 years).
Patients with hepatic AE must, as a matter of course, be screened for possible lung involvement. Albendazole therapy may slow down disease progression in patients with widespread pulmonary involvement who are not eligible for surgery.
La equinococosis alveolar con afectación pulmonar (PAE) es una enfermedad crónica causada por Echinococcus multilocularis, cuya incidencia es muy baja en los países desarrollados.
Estudio unicéntrico, retrospectivo en el cual se diagnosticaron 34 pacientes con PAE entre enero de 2001 y febrero de 2019 (15 varones y 19 mujeres, edad media: 52,4±15,8 años, rango de edad: 28-78 años) en la Escuela Médica Univesitaria de Ataturk, Erzurum, Turquía.
En el total de los casos incluidos en el estudio el hígado fue el principal órgano afectado. La afectación pulmonar se detectó en el 13% (34/261) de los casos con equinococosis alveolar (AE), y 3 pacientes (8,8%) presentaron tanto metástasis pulmonar como cerebral. De acuerdo con los datos radiológicos, la propagación a los pulmones fue por vía hematógena en 25 pacientes (73,5%), transdiafragmática en 3 pacientes (8,8%) y tanto hematógena como transdiafragmática en 6 pacientes (17,7%). Diecinueve pacientes (55,9%) presentaron PAE con afectación pulmonar bilateral, mientras que 12 pacientes (35,3%) presentaron afectación solo del pulmón derecho y 3 (8,8%) solo del izquierdo. De todos los pacientes, 5 fueron sometidos a cirugía debido a la PAE y 29 recibieron tratamiento médico con albendazol. Tres pacientes fallecieron durante el período de seguimiento (2,5 y 10 años después del diagnóstico de PAE), mientras que 31 continuaron con el seguimiento y el tratamiento durante 5,4±3,8 años de media (1-14 años).
Los pacientes con AE hepática se deben cribar de manera rutinaria para detectar una posible afectación pulmonar. El tratamiento con albendazol puede ralentizar la progresión de la enfermedad en pacientes con afectación pulmonar extendida que no son aptos para cirugía.
Degenerative changes in posterior elements of the spine such as thickening or hypertrophy of the ligamentum flavum (LF) may result in spinal stenosis. In the present study, we aimed to investigate ...the potential factors including age, intervertebral disc degeneration (IDD), facet joint degeneration (FJD), end plate degeneration (EPD), which may affect LF thickening and to reveal the relationship among those factors at each level of lumbar spine by evaluating the magnetic resonance images (MRI).
A total of 200 individuals with low back and/or leg pain complaints who had undergone lumbar MRI were included in this study. The thickness of LF, FJD, IDD and EPD were assessed at all lumbar levels.
Totally 1000 end plates, 1000 intervertebral discs and 2000 facet joints were evaluated and the thicknesses of 2000 LFs were measured from MRI images of 200 patients (100 males and 100 females). The mean age was 46.87 ± 12.47 years. LF thickness was strongly associated with FJD especially on the ipsilateral side. Age and IDD were correlated at whole vertebral levels. The age related changes (LF thickness, FJD, IDD and EPD) were more prominent at L4-L5 vertebral level. However, gender had no effect on LF thickness.
The results of this study suggest that LF thickening may occur independently or could be associated with FJD especially on the ipsilateral side and this relationship is due to the vertebral level. The degree of disc degeneration increases with age and age related changes may be predominantly observed at L4-L5 vertebral level.

For bladder cancer, intravesical chemo/immunotherapy is widely used as adjuvant therapy after surgical transurethral resection. Bacillus Calmette-Guerin (BCG) is a live attenuated Mycobacterium of ...the same family as tuberculosis, that is capable of inducing a local inflammatory response upon instillation into the bladder. Intravesical therapy with BCG has proved to be more effective in the prophylaxis and treatment of superficial bladder tumors than most chemotherapeutic agents used for the same indication. However, compared to intravesical chemotherapy, BCG immunotherapy provokes more pronounced local and systemic reactions. In addition to the commonly induced granulomatous inflammatory changes in the bladder, which produce irritative symptoms, this therapy may cause systemic side effects varying from mild malaise and fever to, in rare instances, life-threatening or fatal sepsis. Nanoparticles with positive surface charge and mucoadhesive properties were developed to overcome these side effects. Hence, the aim of this study was to optimize and evaluate cationic chitosan (CS) nanoparticles encapsulating BCG in terms of antitumor efficacy after intravesical administration in bladder tumor, induced in rat model. It was found that nanoparticle formulations of 269-375 nm in size can be produced with 42% encapsulation efficiency. The zeta potential was positive and was suitable for intravesical administration. Antitumor efficacy was determined over the parameters of histopathological evaluation, survival rate and mean bladder weight in comparison to treatment with commercial BCG solution. Concerning survival rates, BCG-loaded chitosan nanoparticles resulted in significantly longer survival than BCG commercial product (up to 86 days of survival with no systemic side effects). When compared to healthy bladder weight averages, all groups (especially BCG commercial solution) showed higher bladder weights confirming tumor formation. Histopathological findings confirmed antitumor activity in all treatment groups and optimum findings were observed in groups treated with CS nanoparticles encapsulating BCG. At the same time, significant nanoparticle accumulation in bladder tissues was observed especially for BCG-loaded CS group. In this study, it was clearly observed that cationic CS nanoparticles provide a significantly improved perspective in intravesical immunotherapy of bladder tumors.
To assess the reference values of M-mode echocardiographic measurements in healthy newborns according to body weight.
From January, 2008 to June, 2008, a total of 250 - 130 female and 120 male - term ...healthy newborns were included in the study. M-mode echocardiographic measurements were recorded by a paediatric cardiologist in accordance with the American Society of Echocardiography recommendations. Right ventricular anterior wall end-diastolic thickness, right ventricular end-diastolic diameter, interventricular septum end-diastolic thickness, left ventricular end-diastolic diameter, left ventricular posterior wall end-diastolic thickness, interventricular septum end-systolic thickness, left ventricular end-systolic diameter, left ventricular posterior wall end-systolic thickness, aortic root dimension, left atrium dimension, left ventricular ejection, and shortening fraction were measured.
The values of echocardiographic measurements revealed a good correlation with body weight. When body weight increased, the measured values also increased in parallel. The measured values were not influenced by gender. Ejection and shortening fraction parameters did not change with body weight and gender.
In this study, normative values related to body weight for cardiac chambers and wall thickness were determined in healthy newborns. These reference values can be used to evaluate whether newborns have normal or abnormal echocardiographic measurement.
Castleman disease (CD) is a rare disease also known as angiofollicular lymph node hyperplasia. The two main histological subtypes are the hyaline vascular and plasma cell variants. It is further ...classified as unicentric CD (UCD) or multicentric CD (MCD) according to the anatomical distribution of the disease and the number of lymph nodes involved. The aim of this multicenter study was to evaluate all cases of CD identified to date in Turkey to set up a national registry to improve the early recognition, treatment, and follow-up of CD.
Both adult (n=130) and pediatric (n=10) patients with lymph node or involved field biopsy results reported as CD were included in the study. Patients’ demographic information, clinical and laboratory characteristics, imaging study results, treatment strategies, and clinical outcomes were evaluated retrospectively.
A total of 140 patients (69 male and 71 female) with a diagnosis of UCD (n=73) or MCD (n=67) were included. The mean age was 39 years in the UCD group and 47 years in the MCD group. Female patients were more common in the UCD group. The most common histological subtype was hyaline vascular for both UCD and MCD patients. Asymptomatic patients were more common in the UCD group. Anemia, elevations of acute phase reactants, and hypoalbuminemia were more common in the MCD group. The most commonly used treatment strategies for UCD were surgical excision, rituximab, and radiotherapy, respectively. All UCD patients were alive at a median of 19.5 months of follow-up. The most commonly used treatment strategies for MCD were methyl prednisolone, R-CHOP, R-CVP, and rituximab. Thirteen MCD patients had died at a median of 34 months of follow-up.
This study is important in presenting the patient characteristics and treatment strategies for CD from Turkey, with the potential of increasing awareness about CD. Treatment data may help in making decisions, particularly in countries that do not have access to siltuximab. However, larger prospective studies are needed to make definitive conclusions.
Social media, through the Internet and other web-based technologies, have become a means of communication and knowledge-sharing. In this article, we provide details about the social media traffic of ...various scientific activities, the organizations of which we have played an active role in. We also provide information in our native language through our FOAMed website, which has been published for about 30 months, with us acting as editors. We are comparing these local and limited ventures with examples from the world and aim to remind that social media sources play a very important role in sharing knowledge in medical training and encouraging local initiatives, like ours, with limited resources.
Objective: Radial shock wave therapy (RSWT) has increasingly been utilized in the treatment of spasticity recently. The purpose of the current study is to assess the effectiveness of RSWT in the ...treatment of ankle plantar flexor muscles spasticity of stroke patients by pedobarography and clinical evaluation.
Materials and Methods: A total of 23 stroke patients were enrolled into the study. Patients received an initial sham treatment of RSWT, followed by three separate interventional sessions received one week apart. Treatment success was assessed using the Modified Ashworth Scale (MAS), ankle passive range of motion (pROM) measurement and pedobarography.
Results and Discussion: No significant change was observed in clinical and pedobarographic values following sham RSWT. In the intervention group, however, MAS decreased from3.34±0.7 to 2.39±0.89 after a single RSWT session and to 2.04±0.92 first week and to 2.52±0.89 fourth week after three RSWT sessions. As a result of the study, heel peak pressure and total plantar contact area were improved. In particular, three RSWT sessions were more effective than single RSWT session.
Conclusions: We observed a significant improvement in plantar flexor spasticity in stroke patients after both a single and three RSWT sessions and this improvement persisted during the four-week study period.

Hypogonadism is a clinical condition that occurs due to infrequent abnormalities in the hypothalamic-pituitary-gonadal (HPG) axis in adolescence. Symptoms include weakening of muscle and bone ...strength. 30 young male patients with congenital hypogonadotropic hypogonadism (CHH) and 20 healthy young males were included in the present study. Quadriceps and hamstring muscle strength, balance and anaerobic performance capacities of the study group were measured both before and six months after Testosterone replacement therapy (TRT). The strength of the extensor and flexor muscles of both legs showed a statistically significant increase in the isokinetic test values at 600/sec and 1800/sec angular velocity (p < 0.05). When the parameters related to balance were investigated, a statistically significant difference was found for stability indices of left and right between pre-TRT and post-TRT (p = 0.001 for both comparisons). According to the patients’ anaerobic performance measurement results, a statistically significant improvement (p < 0.001) was also found between pre-TRT and post-TRT values for each parameter. It was shown that TRT significantly increases muscle strength, balance, and anaerobic performance of patients with male CHH. As a result, we absolutely recommend the use of TRT in patients with male CHH.
