Suicide as globalisation's Black Swan: global evidence.

OBJECTIVES: This empirical study investigated the relationship between globalisation and suicide rates. We examined whether there is a beneficial or harmful relationship between economic, political and social globalisation and the suicide rate. We also estimated whether this relationship differs in high-, middle- and low-income countries. STUDY DESIGN: Using panel data from 190 countries over the period 1990-2019, we examined the relationship between globalisation and suicide. METHOD: We compared the estimated effect of globalisation on suicide rates using robust fixed-effects models. Our results were robust to dynamic models and models with country-specific time trends. RESULTS: The effect of the KOF Globalisation Index on suicide was initially positive, leading to an increase in the suicide rate before decreasing. Concerning the effects of economic, political, and social dimensions of globalisation, we found a similar inverted U-shaped relationship. Unlike the middle-income and high-income countries, we found a U-shaped relationship for the case of low-income countries, indicating that suicide decreased with globalisation and then increased as globalisation continues to increase. Moreover, the effect of political globalisation disappeared in low-income countries. CONCLUSION: Policy-makers in high- and middle-income countries, below the turning points, and low-income countries, above the turning points, must protect vulnerable groups from globalisation's disruptive forces, which can increase social inequality. Consideration of local and global factors of suicide will potentially stimulate the development of measures that might reduce the suicide rate.

Factors effecting natural course of egg allergy.

Summary: Background. There is limited data about the natural course of egg allergy in the literature. We aimed to analyze the factors that can affect the tolerance or persistence of egg allergy. Methods. A total number of 126 IgE- mediated egg allergic patient who had data about tolerance gaining were included in the study. Demographic and laboratory data were recorded retrospectively. Kaplan-Meier curves was used for estimation of resolution and the factors related to resolution by Cox regression model. Results. Among 126 patients 81 (64.2%) had gained tolerance with a median survival time of 48 months (min 12- max 121). Tolerance was gained in 22.2% (28) of these patients in the first 2 years, in 46.8% (49) 2-6 years, 3.1% (4) between 7-12 years. In univariate analysis, no history of anaphylaxis (at initiation or during OFC) (Hazard ratio 2.193; 95%CI 1.309-3.674, p = 0.003), baseline sIgE level less than 8.2 (Hazard ratio 11.292; 95%CI 2.766-46.090, p = 0.001) and baseline egg SPT less than 11 mm (Hazard ratio 2.906; 95%CI 1.424-5.930, p = 0.003) were found to be related to earlier resolution of egg allergy. In multivariate analysis only anaphylaxis was significantly related to later resolution (Hazard ratio: 6.547; 95%CI 15.80-27.434, p = 0.01). Conclusions. Higher levels of egg sIgE, skin prick test induration and anaphylaxis at onset or during oral food challenge, can give hint about persistence of egg allergy.

The impact of digital game addiction on musculoskeletal system of secondary school children.

BACKGROUND: The widespread use of digital devices causes adolescents to spend long periods of time in front of the screen. AIMS: This study aimed to analyze the impacts of digital game addiction on the musculoskeletal system of secondary school children in Kayseri. PATIENTS AND METHODS: A total of 1000 healthy children have been included. A questionnaire, which has been prepared by the researchers and questions children's socio-demographic knowledge, sport habits, durations of study, types of digital tools they use to play games, using positions and durations of use, has been applied to the children. A visual analog scale was used to assess pain intensity. Game addiction has been evaluated through Computer Game Addiction Scale for Children. RESULTS: Between computer and phone use and neck pain, a significant correlation has been found (P < 0.05). Between game addiction and wrist, back and low back pain, a significant correlation has been detected. While males use more computer, tablet and are more addicted to games, the scores of head, wrist and back pain in females have been found out to be significantly high. CONCLUSIONS: As they cause musculoskeletal problems, the higher the time children consume in front of digital devices and the more they use it in wrong posture; the more the complaints about pain are.

Radiolabeled Tedizolid Phosphate Liposomes for Topical Application: Design, Characterization, and Evaluation of Cellular Binding Capacity.

Nowadays, the incidence of acute bacterial skin and skin structure infection (ABSSSI) is increasing. The increased bioavailability and reduced drug resistance of antibiotics are crucial to obtain a more effective treatment response in these infections. These favorable properties could be achieved by different drug delivery systems such as liposomes. In this study, nanosized, radiolabeled tedizolid phosphate liposomal formulations were prepared and evaluated with their in vitro cellular binding capacity and biocompatible profile for topical treatment of ABSSSI. Liposomes were characterized by evaluation of their visual inspection, particle size (about 190-270 nm), zeta potential value (around 0), and encapsulation efficiency (nearly 10%). The release rate of tedizolid phosphate from liposomes was also studied using dialysis membranes and evaluated kinetically. The stability of formulations was observed at three different temperatures and humidity conditions for 28 days. Afterward, liposomes were labeled with 99mTc, and the optimal amount of reducing agent (stannous chloride) was determined as 500 µg in this direct labeling procedure. All liposome formulations were successfully radiolabeled with high efficiency and exhibited high radiochemical purity (> 80%) during 6 h in different media. Furthermore, the cellular bindings of liposomal formulations were evaluated in human skin fibroblast cells by measuring the radioactivity. Higher radioactivity values were obtained in CCD-1070Sk cells incubated by liposome formulations compared to sodium pertechnetate. This finding suggested that liposomal formulation increased the cellular binding of radioactivity. By the result of our study, nanosized, tedizolid phosphate encapsulated liposome formulation was found to be a favorable carrier system in the treatment of ABSSSI.

Bibliometric analysis of publications on house dust mites during 1980-2018.

BACKGROUND: The global prevalence of allergic diseases has increased dramatically in recent years and are now recognized as significant chronic diseases worldwide. One of the most important allergens that causes allergic diseases is house dust mites. OBJECTIVE: This study aims to present a bibliometric overview of research published on dust mites between 1980 and 2018. METHODS: Articles published from 1980 to 2018 were analyzed using bibliometric methods. The keywords "Dust mite*," and "Dermatophagoides" were used in the Web of Science (WoS). Simple linear regression analysis was used to estimate the number of future publications on this subject. RESULTS: A total of 4742 publications were found, 2552 (53.8%) of them were articles. Most of the articles were on subjects related to immunology (1274; 49.9%) and allergy (1229; 48.1%). Clinical and Experimental Allergy (222; 8.7%) was the journal with the most publications. The USA was the country that most contributed to the literature with 461 (18.1%) articles. The countries producing the most publications on this subject were developed countries. The most active author was W.R. Thomas (66; 2.5%). The most productive institution was the University of Western Australia (91; 3.6%). The most cited article was published in the New England Journal of Medicine. CONCLUSION: According to the findings, developed countries were the most productive in publishing on house dust mites. By planning multinational research rather than regional studies, it may be suggested that researchers in underdeveloped or developing countries could also conduct more research on this subject.

Influence of uridine diphosphate-glucuronosyltransferases (1A9) polymorphisms on mycophenolic acid pharmacokinetics in patients with renal transplant.

BACKGROUND: There are differences in pharmacokinetic of mycophenolic acid among individuals. The UGT1A9 enzyme is of special interest since it is the main enzyme involved in the glucuronidation of MPA. Single nucleotide polymorphisms in the UGT1A9 gene may be responsible for individual differences in the pharmacokinetics of MPA. The aim of this study was to explain MPA pharmacokinetics in UGT1A9 1399 C > T polymorphisms in Turkish renal transplant patients. PATIENTS AND METHODS: One hundred and twenty-five living-donor transplant recipients and 100 healthy control subjects underwent UGT1A9 1399 C > T genotyping using polymerase chain reaction-restriction fragment length polymorphism. Concentrations of MPA were determined with Cloned Enzyme Donor Immunoassay (CEDIA). Besides that, all the patients were monitored for acute rejection and graft function during the study period. RESULTS: The UGT1A9 1399 C > T CC, CT, and TT genotype frequencies among patients were, respectively, 68.0%, 23.2%, and 8.8%. The CC, CT, and TT genotype frequencies among controls were, respectively, 63.0%, 23.0%, and 14.0%. There was no significant difference between patients and controls (p = .480, p = .999, p = .286, respectively). At first month, respectively, through blood concentrations of MPA were significantly higher in UGT1A9 1399 C > T TT carriers than in CT and CC carriers (p = .046). The doses for these patients were lower at first month (p = .021). Acute rejection episodes were not associated with the CC vs CT or TT genotypes (p = .064). CONCLUSIONS: Our results demonstrated a correlation between the UGT1A9 1399 C > T polymorphism and MPA pharmacokinetics among renal transplant patients. Determination of UGT1A9 polymorphism may help to achieve target of MPA blood concentrations.

Bibliometric analysis on global Behçet disease publications during 1980-2014: is there a Silk Road in the literature?

BACKGROUND: Behçet disease (BD) is a chronic and multisystemic vasculitis characterized with recurrent oral and genital ulcers, uveitis, arthritis and skin manifestations. The highest prevalence of the disease has been reported in regions historically involved in the Silk Road routes. OBJECTIVE: We aimed to analyse Behçet literature and evaluate whether there is a concordance between ancient Silk Road regions and the distribution of publication productivity. METHODS: The bibliometric analysis of the publications published during 1980-2014 using Thomson Reuters Web of Science database was performed. We generated infographics of productivity and also analysed the correlations among economical productivities, technological advancement levels and humanity index and productivity performances of 78 countries in Behçet literature. RESULTS: Turkey ranked first in Behçet literature with 1837 articles followed by Japan and the USA. Turkey, Tunisia and Israel occupied the first three places in productivity. Significant correlations were noted between 2014 gross economic and technological indices and publication numbers of the countries. We found that European countries had high productivity, although they had low prevalence of BD. We detected no concordance between the productivity density of the countries and the ancient Silk Road routes. CONCLUSION: Most publications were reported from developed countries although undeveloped or developing countries had higher prevalence of BD. Physicians in undeveloped and developing countries should be supported and encouraged to perform novel studies on BD.

Prokinetics stimulate the increase of ghrelin in mice.

OBJECTIVES: Intestinal motility is regulated by several neurotransmitters and neuropeptides including dopamine and acetylcholine as well as ghrelin. Metoclopramide and domperidone are long-standing treatment options for dysmotility, and erythromycin is suggested in selected patients. In the present study, we aimed to investigate the effects of mentioned prokinetics on ghrelin levels. METHODS: Serum ghrelin levels were estimated by using enzyme-linked immunoassay following a single administration of domperidone, metoclopramide, or erythromycin. RESULTS: Our results showed that both antidopaminergic and cholinergic prokinetics increase the circulating ghrelin levels. There was no significant difference between enteral and parenteral control groups. Also, statistical analysis revealed that neither prokinetic was superior to the other in regard to its ghrelin stimulating effect. CONCLUSION: Conclusively, the present study demonstrated that the circulating levels of ghrelin increase by the administration of antidopaminergic and cholinergic prokinetics. Hence, this effect on ghrelin may partly be responsible for the motility­stimulating actions of domperidone, metoclopramide, and erythromycin (Fig. 2, Ref. 39).

Co-administration of cisplatin and curcumin does not alter mood-associated behaviors.

OBJECTIVES: Cisplatin (cis-diamminedichloroplatinum (II)) is a widely-used platinum-based chemotherapeutic agent which has dose-limiting side-effects. Also, the drug resistance is another instance that decreases treatment success in cisplatin chemotherapy. The growing body of evidence suggests that curcumin, a polyphenolic compound extracted from the spice turmeric, may exert synergistic effects and sensitize malign cells to cisplatin, while alleviating cytotoxicity-related side-effects. The present study was aimed to investigate mood-associated interactions between cisplatin and curcumin. MATERIALS AND METHODS: Thirty-four adult male Wistar albino rats were randomly assigned to four groups as control, curcumin (300 mg/kg/day, p.o. for 5 weeks), cisplatin (5 mg/kg/week, i.p. for 5 weeks), and curcumin plus cisplatin (same doses as above). The open field, elevated plus maze, and forced swim tests were engaged to evaluate mood-associated behaviors. RESULTS: We demonstrated that depression- and anxiety-like behaviors were not altered by the administration of curcumin along with the chronic cisplatin treatment. CONCLUSION: According to the results of the present study, we concluded that curcumin might be regarded as a safe adjuvant in cisplatin chemotherapy in terms of the mood-associated behaviors (Fig. 4, Ref. 41).

The Radioprotective Effects of Caffeic Acid Phenethyl Ester and Thymoquinone on Oxidative and Nitrosative Stress in Liver Tissue of Rats Exposed to Total Head Irradiation.

OBJECTIVE: The aim of this study is to investigate the effects of addition of caffeic acid phenethyl ester (CAPE) and thymoquinone (TQ) on oxidative and nitrosative stress in the liver tissue of irradiated rats. METHODS: Forty Sprague-Dawley rats were divided into five groups to test the radioprotective effectiveness of TQ and CAPE administered by intraperitoneal injection. Appropriate control groups were also studied. RESULTS: Liver antioxidant capacity, as measured by levels of total superoxide scavenger activity (TSSA), non-enzymatic superoxide scavenger activity (NSSA) and glutathione-S-transferase (GST) activity except superoxide dismutase (SOD) activity, were statistically lower in the irradiation (IR) group compared to all other groups. Total superoxide scavenger activity and NSSA were statistically higher in the IR plus TQ and IR plus CAPE groups compared to all other groups. In contrast, glutathione peroxidase (GSH-Px) activity was significantly found to increase in the IR plus CAPE group compared to control groups. The xanthine oxidase (XO), nitric oxide synthase (NOS) activities, nitric oxide (NO●) and malondialdehyde (MDA) levels in the IR group were statistically higher than in the other groups. Moreover, XO activity in the IR plus TQ group was statistically lower than all other groups including the IR plus CAPE group. In addition, NO● level was found to increase in all groups when compared to the normal control group. CONCLUSIONS: Thymoquinone and CAPE decrease oxidative and nitrosative stress markers and have antioxidant effects, which also increase antioxidant capacity in the liver tissue of irradiated rats.

Radio-protective effects of Nigella sativa oil on oxidative stress in tongue tissue of rats.

OBJECTIVE: The aim of this study was to evaluate the effects of Nigella sativa (N.S.) oil against radiation-induced oxidative stress in the rat tongue. MATERIAL AND METHODS: Thirty-two Sprague-Dawley rats were randomly divided into four equal groups. Group 1 [control group(C)] did not receive N.S. oil or irradiation. Group 2 [sham control group(CN)] did not receive N.S. oil or irradiation but received 1-ml saline orally, plus sham irradiation. Group 3 [irradiation group(R)] received irradiation, plus 1-ml saline orally. Group 4 [irradiation plus N.S. oil group(RN)] received irradiation plus 1 g kg(-1) per day of N.S. oil orally for 10 days. The animals were euthanized on day 10, and tongue tissues were collected for evaluating biochemical oxidative parameters. RESULTS: The oxidative stress index, total oxidant status and lipid hydroperoxides levels in the R group were statistically higher than those in the C, CN and RN groups. The paraoxonase levels in the R group were statistically lower than those in the C, CN and RN groups. No statistically significant differences were detected between any of the groups, in terms of total antioxidant status and the arylesterase, ceruloplasmin and total sulfhydryl group levels. CONCLUSION: Nigella sativa (N.S.) oil may be a beneficial agent in protecting against ionizing radiation-related tissue injury.

The gene encoding gigaxonin, a new member of the cytoskeletal BTB/kelch repeat family, is mutated in giant axonal neuropathy.

Disorganization of the neurofilament network is a prominent feature of several neurodegenerative disorders including amyotrophic lateral sclerosis (ALS), infantile spinal muscular atrophy and axonal Charcot-Marie-Tooth disease. Giant axonal neuropathy (GAN, MIM 256850), a severe, autosomal recessive sensorimotor neuropathy affecting both the peripheral nerves and the central nervous system, is characterized by neurofilament accumulation, leading to segmental distension of the axons. GAN corresponds to a generalized disorganization of the cytoskeletal intermediate filaments (IFs), to which neurofilaments belong, as abnormal aggregation of multiple tissue-specific IFs has been reported: vimentin in endothelial cells, Schwann cells and cultured skin fibroblasts, and glial fibrillary acidic protein (GFAP) in astrocytes. Keratin IFs also seem to be alterated, as most patients present characteristic curly or kinky hairs. We report here identification of the gene GAN, which encodes a novel, ubiquitously expressed protein we have named gigaxonin. We found one frameshift, four nonsense and nine missense mutations in GAN of GAN patients. Gigaxonin is composed of an amino-terminal BTB (for Broad-Complex, Tramtrack and Bric a brac) domain followed by a six kelch repeats, which are predicted to adopt a beta-propeller shape. Distantly related proteins sharing a similar domain organization have various functions associated with the cytoskeleton, predicting that gigaxonin is a novel and distinct cytoskeletal protein that may represent a general pathological target for other neurodegenerative disorders with alterations in the neurofilament network.

A bibliometric perspective with research trends and global productivity on the modernization of andrology from the founder of modern clinical andrology Edward Martin to the present.

OBJECTIVE: The number of studies in the field of andrology is increasing day by day, but a bibliometric study covering the entire literature on andrology has not yet been conducted. This bibliometric study aims to shed light on the question of where we came from and where we are going in andrology from past to present. It also aimed to summarize the intellectual structure of andrology to reveal global productivity and identify and map the latest trends of scientific articles published in the field of andrology. MATERIALS AND METHODS: 16,659 articles published between 1980 and 2022 were extracted from the Web of Science and analyzed using various statistical methods. Bibliometric network visualization maps revealed trending topics, global productivity, the most influential studies, and international collaborations. Spearman's correlation analysis was used for determining correlations. RESULTS: The top three productive countries were United States of America (3,452; 20.7%), China (2,300; 13.8%), and Germany (1,069; 6.4%). The top two most productive authors were Agarwal A. (n=130) and Nieschlag E. (n=130). The most productive institution was the Egyptian Knowledge Bank (n=422). From past to present, the most studied subjects were testis, male infertility, spermatozoa, testosterone, infertility, erectile dysfunction, spermatogenesis, sperm, prostate cancer (PCA)/neoplasms, oxidative stress, fertility/fertilization, semen, rat(s), apoptosis, azoospermia, sperm motility, human and varicocele. CONCLUSIONS: The trend topics that have been researched more in recent years include erectile dysfunction, oxidative stress, prostate cancer, sperm quality, sperm parameters, infertility, premature ejaculation, diabetes mellitus, obesity, prognosis, sperm DNA fragmentation/damage, antioxidant, asthenozoospermia, varicocelectomy, COVID-19, inflammation, prostatectomy, metabolic syndrome, hypogonadism, benign prostatic hyperplasia, lower urinary tract symptoms, meta-analysis, sexual dysfunction, peyronie's disease, and proliferation. We identified the research leadership of China, Japan, Turkey and India, in addition to Western countries, such as the USA and European countries.

Alpha-linolenic acid protects against methotrexate-induced nephrotoxicity in mouse kidney cells.

OBJECTIVE: Methotrexate (MTX) is a folic acid antagonist used in chronic inflammatory diseases and various cancer treatments. Although the main mechanism of the toxic effect of MTX is not known, it is stated that it causes oxidative stress and inflammation. Alpha-linolenic acid (ALA) protects against oxidative stress, apoptosis, and inflammation. For this reason, we aimed to find out the useful effect of ALA on MTX-induced nephrotoxicity MATERIALS AND METHODS: The mice were divided into 4 groups randomly. The control group was treated with physiological saline solution; the ALA group was treated with ALA (200 mg/kg) by gavage; MTX-treated group received 20 mg/kg i.p. (intraperitoneal) MTX; and MTX+ALA treated group received 20 mg/kg i.p. MTX and ALA 200 mg/kg by gavage. All of the drugs were performed once a day for 9 days. RESULTS: Alpha-linolenic acid significantly decreased oxidative stress parameters and MTX-induced inflammatory and apoptotic mediators. Furthermore, histopathological examination showed that MTX induced significant edematous damage, and ALA treatment attenuated this damage in renal tissue. CONCLUSIONS: Our results revealed that ALA may be helpful against MTX-induced nephrotoxicity in mice via its antioxidant and anti-inflammatory properties.

Biomechanical evaluation of caudally and buccally screwed customised reconstruction plates for lateral segmental defects of mandible.

The aim of this study was to compare locking reconstruction plates with caudobuccally screwed custom mandibular reconstruction plates in bridging lateral mandibular segmental defects. The in vitro study was conducted on 13 polyurethane mandibles. A total of 7 mandibles with lateral segmental defects were bridged with locking reconstruction plates in group I, 6 mandibles with the same standard defect were bridged with caudobuccally screwed customised reconstruction plates in group II. Mean yield displacement, yield load, and displacement at 80 N (Newtons), 100 N, 200 N, 300 N loading were compared among the 2 groups. The mean (SD) displacement for Group I was 11.27 (3.6) mm, Group II was 21.08 (2.5) mm. Group II had significantly greater (p=0.0001) displacement when compared with Group I. The mean (SD) force before failure for Group I was 638.4 N (127.2), Group II was 1398. 3 N (162.7). Group II withstood significantly greater force than Group I (p=0.0001). The study reveals that the caudobuccally screwed custom reconstruction plates can significantly enhance yield load as preserving the preoperative shape of the face and mandible.

Influence Of Pre-Existing Neurological Illnesses On The Outcome Of Severe Burn Injuries.

It is known that patients suffering from neurological illnesses have an increased risk of burn injuries. These burns are often very severe and lead to poor outcomes. To date, only a few studies have evaluated the impact of pre-existing neurological illnesses on the outcome of burn injuries. None of them performed a regression analysis regarding specific influence on mortality. Between 1996 and 2016, 1475 patients were admitted to the BICU of a specialized German burn center: 26 had less than 1% TBSA burned and were excluded; 177 had pre-existing neurological disorders (group N). 87 patients with psychological disorders were excluded. 1185 patients without neurological or psychological disorders formed the control group. Length of hospital stay, TBSA and number of operations were analyzed using the chi-squared test and Mann-Whitney U-test. Additionally, mortality was evaluated using the logistic regression analysis adjusted for known outcome predictors. Mean age of the patients in the control group was 41.53 years with a BICU stay of 18 days, TBSA of 18.25% and mortality rate of 12.4%; 23.7% had inhalation injuries. Patients in group N had a mean age of 54.63 years, a BICU stay of 27 days, mean TBSA of 20.97%; 31.1% had inhalation injuries and mortality was 20.3%. Patients with neurological disorders were older and showed higher affected TBSA, higher rates of inhalation injury, mortality and affected TBSA, and a longer stay in the BICU compared to the control group. Nevertheless, pre-existing neurological disorders alone had no significant influence on mortality.

Il est avéré que les patients souffrant de pathologie neurologique ont un risque plus élevé de brûlure. Elles sont souvent particulièrement graves et d'évolution défavorable mais la littérature à ce sujet reste pauvre et aucune étude n'a utilisé de régression logistique pour évaluer la corrélation pathologie neurologique- évolution d'une brûlure. Entre 1996 et 2016, 1 475 patients ont été hospitalisés en réanimation spécifique dans un CTB allemand. Vingt- six d'entre eux, brûlés sur moins de 1% SCT, n'ont pas été inclus dans l'étude, pas plus 87 patients psychiatriques si bien que 177 patients souffrant de pathologie neurologique (N) ont été comparés à 1 185 n'en souffrant pas (C). Les durées d'hospitalisation, la surface brûlée et le nombre d'interventions chirurgicales ont été analysée en utilisant C² ou Mann-Whitney. En outre, nous avons effectué une régression logistique étudiant la mortalité, en utilisant les facteurs connus de mortalité. Le groupe C avait 41,53 ans, souffrait de brûlures sur 18,25% SCT, avait inhalé des fumées dans 23,7% des cas, avait un taux de mortalité de 12,4% et restait 18 j en réanimation. Dans le groupe N, ces chiffres étaient respectivement de 54,63 ans, 20,97% SCT, 31,1% de fumées, 20,3% de mortalité et 27 jours en réa. Tous les chiffres étudiés étaient plus élevés dans N que dans C. Toutefois, l'existence de comorbidité neurologique n'apparaissait pas un critère indépendant de mortalité.

Cardio-facio-cutaneous syndrome: phenotypic variability and differential diagnosis in 3 cases with de novo BRAF mutations.

Cardio-facio-cutaneous (CFC) syndrome is a developmental disorder causing mental retardation and multiple congenital anomalies, including craniofacial, ectodermal, cardiac and musculoskeletal defects. Mutation of several genes in the RAS/MAPK (mitogen activated protein kinase) signaling pathway, most commonly BRAF, results in CFC syndrome. In this study, we report 3 new patients with CFC syndrome caused by mutation of BRAF. These patients differed in neurological impairment, craniofacial features and cardiac defects, while they shared relatively similar ectodermal and skeletal anomalies. They also displayed some overlapping features with Costello syndrome, another RAS/MAPK pathway disorder. Our findings highlight the clinical variability of CFC syndrome, with respect to severity and pattern of the affected organs, as well as the phenotypic overlap with the Costello syndrome.

Relationship of lumbar disc degeneration with hemoglobin value and smoking.

BACKGROUND/OBJECTIVE: Although a number of studies report an important effect of smoking on disc degeneration and herniation, others did not identify such a relationship. The purpose of this study was to assess the relationship of lumbar disc degeneration with hemoglobin value and smoking. METHODS: The study included 200 adult patients who presented to the neurosurgery polyclinic with a complaint of back pain. Smoking habits were classified as "smoking for more than 10 years", "smoking for less than 10 years", and "not smoking". Lumbar disc degeneration was classified on modified Pfirrmann score according to lumbar MR images. Degeneration level was compared according to smoking group on Kruskal-Wallis test. The relationship between hemoglobin value and disc degeneration according to smoking group was assessed on the Spearman correlation coefficient. RESULTS: Disc degeneration values were significantly different between groups in L5-S1, L4-L5 and L3-L4 (P=0.018, P=0.012, P=0.038). Degeneration levels in L5-S1 in those who did not smoke were significantly lower than in those who smoked for both less and more than 10 years (P=0.048, P=0.022). No significant differences were found in degeneration level between those who smoked for more versus less than 10 years. For L3-L4 degeneration, there was a significant relationship with hemoglobin value in the group that did not smoke and in the group that smoked for more than 10 years (r=-0.395; P=0.009, r=0.329; P=0.018). CONCLUSION: This study found that, when risk factors such as systemic disease, heavy working conditions, obesity, trauma and family history were excluded, smoking increased lumbar disc degeneration. In addition, chronic smoking was found to increase hemoglobin values.

Outcome of eminectomy combined with discectomy and silastic interpositional graft for temporomandibular joint dysfunction: a retrospective study of 20 years.

Internal derangement of the temporomandibular joint (TMJ) is usually treated conservatively, but about 5% require surgical treatment. We designed a retrospective study to assess the long-term outcomes of eminectomy combined with discectomy and silastic interpositional graft in 44 patients who had chronic TMJ dysfunction that had not responded to traditional conservative treatment and arthrocentesis. The maximum mouth opening, pain score, Wilkes stage, and clinical dysfunction index were measured before, and two years after, operation. All the patients showed significant improvement in mouth opening and reduced pain scores (p<0.0001 in each case). There were no long-term operative complications, and postoperative magnetic resonance scans showed that the silastic interpositional graft was in a stable position with no evidence of degenerative changes on the surfaces of the joint and no lymphadenopathy.

Association of bacteria in pancreatic fistula fluid with complications after pancreatic surgery.

BACKGROUND: Pancreatic fistula (PF) is a common complication after pancreatic surgery. It is unclear how microbes in PF fluid affect outcomes and which microbes are present after pancreatoduodenectomy (PD) and distal pancreatectomy (DP). The aim of this study was to compare the microbiological spectrum of PF fluid after PD versus DP, and its association with postoperative complications. METHODS: Bacterial strains and antibiotic resistance rates of bacterial swabs obtained from the PF fluid of patients who underwent DP or PD were analysed. Cultured bacteria were classified as Enterobacterales and as 'other intestinal and non-intestinal microorganisms' based on whether they are typically part of the normal human intestinal flora. RESULTS: A total of 847 patients had a pancreatic resection (PD 600; DP 247) between July 2007 and December 2016. Clinically relevant PF was detected in 131 patients (15·5 per cent). Bacterial swabs were obtained from 108 patients (DP 47; PD 61), of which 19 (17·6 per cent) were sterile. Enterobacterales were detected in 74 per cent of PF fluid swabs after PD, and in 34 per cent after DP. Infected, polymicrobial or multidrug-resistant PF fluid was more common after PD (rates of 95, 50 and 48 per cent respectively) than after DP (66, 26 and 6 per cent respectively). Patients with higher grade complications (Clavien-Dindo grade IV-V) or grade C PF had more Enterobacterales and multidrug-resistant Enterobacterales in the PF fluid after DP. CONCLUSION: Enterobacterales and multidrug-resistant bacteria are detected frequently after PD and DP, and are associated with more severe complications and PF in patients undergoing DP.

ANTECEDENTES: La fístula pancreática (pancreatic fistula, PF) es una complicación frecuente de la cirugía pancreática. No está claro cómo los microorganismos que se encuentran en el líquido de la PF (pancreatic fistula fluid, PFF) afectan los resultados y qué microbios están presentes después de la duodenopancreatectomía (pancreaticoduodenectomy, PD) y de la pancreatectomía distal (distal pancreatectomy, DP). El objetivo de este estudio fue comparar el espectro microbiológico del PFF después de PD versus DP y su asociación con las complicaciones postoperatorias. MÉTODOS: Se analizaron las cepas bacterianas y las tasas de resistencia a los antibióticos de las muestras bacterianas obtenidas del PFF de pacientes de nuestra institución que se sometieron a DP o PD. Las bacterias identificadas en los cultivos se clasificaron en "enterobacterias" y "otros microorganismos intestinales y no intestinales" en función de si típicamente forman parte de la flora intestinal humana normal o no. RESULTADOS: Un total de 847 pacientes se sometieron a resección pancreática (PD: 600, DP: 247) entre julio de 2007 y diciembre de 2016, y se detectó FP clínicamente relevante en 131 pacientes (15,5%). Se obtuvieron muestras bacterianas de 108 pacientes (DP n = 47, PD N = 61), de los cuales 19 (18%) eran estériles. Se detectaron enterobacterias en el 74% del PFF después de PD y en el 34% después de DP. El PFF infectado, con flora polimicrobiana o flora multirresistente fue más frecuente después de la PD (95,1%, 50%, 47,5%, respectivamente) que después de la DP (66,0%, 25,8%, 6,4%, respectivamente). Los pacientes con complicaciones de grado superior (Clavien-Dindo 4/5) o PF grado C presentaron más enterobacterias y enterobacterias multirresistentes en el PFF después de DP. CONCLUSIÓN: Las enterobacterias y las bacterias multirresistentes se detectaron con frecuencia después de la PD y la DP, y se asociaron a complicaciones más graves y PF en pacientes sometidos a DP.
