Comparison of Cases with Anterior Cruciate Ligament Reconstruction Accompanied by Simultaneous Medial Meniscus Bucket Handle Tear Repair and Isolated Medial Meniscus Bucket Handle Tear Repair.

The aim of this study was to evaluate the success of the all-inside repair technique for medial bucket-handle meniscus tear (BHMT) and the factors affecting healing. A total of 36 patients with BHMT who were operated between 2012 and 2018 and completed final follow-up examinations were included in the study. Functional evaluation was made with the International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score. Healing was evaluated on magnetic resonance imaging (MRI) slices. The patients were evaluated with respect to the effect on healing of factors such as demographic data, body mass index (BMI), smoking status, anterior cruciate ligament tear reconstruction (ACLTR) applied at the same time as BHMT repair, and the tear being chronic or acute. The mean age of the patients was 28.6 ± 8.6 years (range,18-46 years), the mean follow-up period was 25.8 ± 13.9 months (range, 13-59 months), and BMI was mean 25.6 ± 3.5 kg/m2 (range, 20.1-30.5 kg/m2). The meniscus tears were acute in 16 (44.4%) patients and chronic in 20 (55.6%). ACLTR was applied together with BHMT repair in 25 patients. The hybrid technique, as the outside-in technique in addition to the all-inside technique, was applied to 12 (33.3%) patients, where there was seen to be extension to the anterior horn. The failure rate was determined as 27.8% according to the postoperative MRI evaluation and the Barrett criteria. No positive or negative statistically significant effect on healing was determined of chronic BHMT or of simultaneous application of ACLTR (p = 1.00 and 0.457, respectively). Cigarette smoking and high BMI were determined to have a statistically significant negative effect on healing (p = 0.026 and 0.007, respectively). In conclusion, it can be seen that the success of the all-inside technique for BHMT remains controversial. Due to the features of the application, it can be used in meniscus tears of the posterior horn only. In the current study, with the success rate of 72.2% of the all-inside technique in meniscus body tears, it was seen that a high success rate could not be achieved.

Periodontal disease as a potential factor for systemic inflammatory response in the dog.

Periodontal disease is an inflammatory disease that has numerous consequences both locally and systemically The aim of this study was to assess whether periodontal disease causes systemic inflammatory response in otherwise healthy, adult dogs. We estimated the total mouth periodontal score (TMPS), measured the concentration of C-reactive protein (CRP), hematocrit, and albumin, and determined the white blood cell (WBC) and polymorphonuclear cell (PMN) counts in client-owned dogs. There was a statistically significant relationship between the gingival bleeding index (TMPS-G) and CRP concentration, and WBC and PMN counts, possibly during the active periods of periodontal tissue destruction. No correlation was found between the periodontal destruction index (TMPS-P) and the measured blood parameters. We conclude that chronic periodontal disease does not cause anemia or a reduction in serum albumin. However, active periods of periodontal inflammation may be associated with laboratory values suggestive of a systemic inflammatory response.

Septic pulmonary embolism: three case reports.

We present three cases of septic pulmonary embolism which occurred as a result of three different causes. The first case, was a 23 year old woman suffering from cough, sputum, hemopthisis and pleuritic chest pain. She had a right subclavian port. On her thorax computed tomography (CT) scans there were widespread bilateral, irregular parenchymal nodular infiltrates and some of them beginning to cavitate. Meticilin resistant stafilococus aureus (MRSA) was isolated from the blood culture and septic embolism was diagnosed. A month after antibiotic theraphy her parenchymal nodules have considerably decreased in size. The second case was a 40 year old woman admitted to our hospital with the same complaints. Her radiological findings were similar. Meticilin sensitive stafilococus aureus (MSSA) was isolated from the blood cultures and antibiotic theraphy was initiated. To investigate the etiology of the nodules due to septic embolism, echocardiography was performed and infective endocarditis was diagnosed. After the antibiotic theraphy and a tricuspid valve operation her parenchymal nodules disappeared. The final case involved a 51 year old man suffering from fever, fatigue, cough and pain in the left arm for one week. His general status was bad. His radiological findings were also similar to the others. Staphillococcus aureus was isolated from blood and wound culture. Following clinical and radiological findings we thought it was a case of septic pulmonary embolism and antibiotic theraphy was started. Despite the therapy we did not take fever response and he died five days after antibiotic therapy. In conclusion, septic pulmonary embolism should be considered in bilateral cavitary nodular infiltrates and must be managed fast.

[Vascular endothelial growth factor in benign and malignant pleural effusions]. / El factor de crecimiento endotelial vascular en los derrames pleurales benignos y malignos.

OBJECTIVE: Vascular endothelial growth factor (VEGF) is a potent inducer of capillary permeability and its role as a crucial mediator in pleural fluid formation has been established. This study was conducted to assess the usefulness of VEGF for diagnosing malignant and non-malignant pleural effusions of various causes. PATIENTS AND METHODS: VEGF levels in pleural effusions collected from 52 patients (20 with malignant effusion, 12 with tuberculous effusion, 10 with transudative effusion, and 10 with parapneumonic effusion) were assessed by enzyme-linked immunosorbent assay. RESULTS: The median level of VEGF was significantly higher (P = .001) in exudative effusions (10.16 pg/mL) than in the transudative effusions (3.82 pg/mL). Although malignant pleural fluids tended to have higher median and mean levels of VEGF compared to tuberculous effusions, the difference was not statistically significant. Pleural VEGF levels in subtypes of lung cancer and in malignant effusions of different origins were not significantly different. CONCLUSIONS: In conclusion, although VEGF levels in pleural effusions of different origins vary, they were only able to discriminate exudates from transudates significantly in this study. Further studies in larger groups of patients are needed to establish the role of VEGF in diagnosing malignant and/or tuberculous effusions.

El factor de crecimiento endotelial vascular en los derrames pleurales benignos y malignos / Vascular endothelial growth factor in benign and malignant pleural effusions

Objetivo: El factor de crecimiento endotelial vascular (VEGF) es un potente inductor de la permeabilidad capilar y desempeña un papel clave como mediador en la formación del derrame pleural. Este estudio se ha realizado para evaluar la utilidad del VEGF en el diagnóstico de los derrames pleurales malignos y no malignos de diversas causas. Pacientes y métodos: Mediante la técnica de inmunoabsorción ligada a enzimas se determinaron las concentraciones de VEGF en los derrames pleurales correspondientes a 52 pacientes (20 con derrame pleural maligno, 12 con derrame de origen tuberculoso, 10 con derrame de tipo trasudado y 10 con derrame paraneumónico). Resultados: La concentración media del VEGF fue significativamente mayor (p = 0,001) en los derrames pleurales (10,16 pg/ml) de tipo exudado que en los derrames de tipo trasudado (3,82 pg/ml). Aunque los derrames pleurales malignos mostraron una tendencia a las concentraciones medianas y medias mayores de VEGF, en comparación con los derrames de origen tuberculoso, la diferencia no fue estadísticamente significativa. Tampoco fueron significativamente diferentes las concentraciones pleurales de VEGF en los distintos subtipos de cáncer pulmonar, y tampoco en los derrames malignos de distintos orígenes. Conclusiones: Aunque las concentraciones de VEGF son distintas en los derrames pleurales de orígenes diferentes, en nuestro estudio no han permitido discriminar los exudados de los trasudados. Son necesarios nuevos estudios de investigación sobre grupos más numerosos de pacientes con objeto de establecer el papel que puede desempeñar la concentración de VEGF en el diagnóstico de los derrames malignos, tuberculosos o ambos

Gastro-oesophageal reflux during thiopentone or propofol anaesthesia in the cat.

Lower oesophageal pH was monitored in 50 cats anaesthetized with either thiopentone or propofol. Gastro-oesophageal reflux, as evidenced by a decrease in lower oesophageal pH to less than 4.0 or an increase to more than 7.5, occurred in 16% (4/25) and 12% (3/25) of the cats anaesthetized with thiopentone and propofol, respectively, the difference between the two groups being non-significant. Reflux usually occurred shortly after the induction of anaesthesia and had a mean duration of about 23 min. The refluxate was always acidic (pH < 4.0). Gastric contents of pH below 2.5 were refluxed on three occasions, two in the thiopentone group and one in the propofol group. Regurgitation and flow of gastric contents from the mouth occurred in only one cat anaesthetized with propofol. None of the cats that exhibited reflux developed any signs of postanaesthetic oesophagitis or stricture formation.

Sister chromatid exchange rate from pleural fluid cells in patients with malignant mesothelioma.

This study assessed the impact of malignant mesothelioma on the frequencies of sister chromatid exchange (SCE) in the pleural effusion cells. Ten patients with mesothelioma and 20 control subjects were included in the study. The control subjects were the patients with tuberculosis pleurisy, and the remaining 10 subjects of control group were healthy volunteers and only heparinized blood samples were collected from these subjects. The pleural effusion cells were cultured with conventional culture methods. The samples were obtained from the patients after histopathologic confirmation of the malignancy but before the initiation of chemotherapy or radiotherapy. At the end of the culture period and 48 h prior the harvesting, BrdU was added into flasks. Totally, 100 metaphases were scored for each sample. In this study, we found that the SCE frequencies of malignant pleural mesotheliomas were significantly higher than the control subjects (P<0.001). Six of 10 patients came from central Anatolia, which is of great importance due to high rate of exposure to asbestosis in this region.

Relationship of passive cigarette smoking to otitis media.

OBJECTIVE: To determine the effect of passive smoking on otitis media with effusion (OME) and recurrent otitis media (ROM). DESIGN: A case-control study of children who received ventilation tubes and who were followed up for 1 year to determine the risk of developing postoperative otorrhea and early extrusion in relation to exposure to passive cigarette smoke. SETTING: Otorhinolaryngology Clinic of Istanbul School of Medicine, Istanbul, Turkey. PATIENTS: A total of 166 children 3 to 7 years old who required tympanostomy tubes because of OME and ROM (case group) compared with an age-matched control group of 166 children. The control group consisted of children who did not meet and never had met criteria for insertion of tympanostomy tubes. MAIN OUTCOME MEASURES: Statistical analysis of factors associated with a higher prevalence of OME or ROM, postoperative otorrhea, and early tube extrusion. RESULTS: Passive smoking was a significant risk factor for OME and ROM. The case group was exposed to a mean of 19.6 cigarettes per day vs 14.4 cigarettes per day for the control group (P<.004). Only maternal smoking was a significant factor (P<.001); no association was found with paternal smoking. Prospective follow-up of the case group showed no significant difference in the clinical course of OME and ROM between maternally exposed and non-maternally exposed children. CONCLUSIONS: Passive smoking increases the risk of OME and ROM in children between 3 and 7 years old. The avoidance of daily exposure to domestic tobacco smoke could have a public health impact.

Chronic effects of welding exposure on pulmonary function tests and respiratory symptoms.

OBJECTIVES: The respiratory effects of exposure to welding fumes have been investigated in numerous studies; but results of these studies have not been consistent. The aim of the present study was to investigate the respiratory effects of welding exposure in a large group of manual are welders exposed primarily to mild steel welding processes in confined spaces without respiratory protection. METHODS: Respiratory symptoms and spirometry were studied in 110 welders and 55 controls. The welders and controls were of similar average age and height; smoking habits of the groups were similar. Chest x ray films were taken to exclude people with radiological abnormalities that may influence pulmonary function tests. Welders were grouped according to smoking habits and duration of employment (< 20 years or > 20 years). RESULTS: No gross radiological abnormalities were found. Respiratory symptoms and chronic bronchitis were more prevalent in welders (P < 0.05). Welders who were smokers showed a higher frequency of chronic bronchitis than controls who smoked (P < 0.05). No significant difference in the occurrence of chronic bronchitis was found between welders who smoked and welders who were non-smokers or exsmokers. Compared with the controls, forced vital capacity (FVC), forced expiratory volume in one second (FEV1), peak expiratory flow (PEF), and maximum midexpiratory flow (MMEF) were significantly lower in welders (mean values of FVC for welders and controls were 86.06 (25.74) and 96.40 (13.03); and values for FEV1 were 87.54 (13.70) and 95.36 (12.40) respectively; P < 0.01). There was no significant difference in pulmonary function tests between welders who were non-smokers and controls who were non-smokers; whereas FVC, FEV1, PEF, and MMEF were significantly lower in welders who smoked than controls who smoked (P < 0.01). There were no significant differences in pulmonary function tests and occurrence of chronic bronchitis between welders with more or less than 20 years at work. CONCLUSION: Welders working in conditions of inadequate ventilation, have increased risk of chronic bronchitis and impairment of pulmonary function.

Polycythemia vera associated with Ushers's symdrome.

A 50-year-old man with Usher's syndrome, progressive retinitis pigmentosa, and congenital sensoneural deafness developed polycythemia vera. Usher's syndrome was associated with a variety of congenital herediatry disorders but there was no evidence to support more than a chance association between Usher's syndrome and polycythemia vera.
