Comparison of head positioning using the Mayfield skull clamp versus padded headrest in anterior cervical discectomy and fusion surgery.

Background: Anterior cervical discectomy and fusion (ACDF) is a commonly implemented surgical intervention for a variety of pathologies affecting the cervical spine. The current literature and daily practice reveal variations on patient head positioning for this procedure with both rigid fixations in the Mayfield skull clamp as well as use of a padded headrest being used. In this study, we therefore examine whether patients undergoing surgery using head positioning in the Mayfield skull clamp versus a padded headrest differ in regard to adverse events, surgical parameters and clinical outcome. Methods: A single-center, retrospective analysis of 121 patients treated with ACDF for degenerative disease, traumatic cervical spine injury and infectious disease between November 2019 and March 2023 was performed. Clinical and imaging data for 59 patients positioned in the Mayfield skull clamp and 62 patients positioned in a padded headrest were evaluated using electronic medical records. In addition to demographic data, surgical indications, procedures performed were analyzed for both groups. Level of training (chief, attending and resident), length of surgery and intraoperative radiation exposure (measured by dose area product and total radiation time) were also examined. Finally, modified Rankin Scale (mRS) preoperatively and at last follow-up as well as adverse events were compared between groups. Results: We found no statistically significant differences between the Mayfield and headrest groups regarding surgical indications (P=0.583), procedures performed (P=0.069), level of training of the surgeon (P=0.218), length of surgery (P=0.752), adverse events (P=0.619) or neurological impairment (P=0.080) following surgical intervention. There was a significant difference regarding dose area product between both groups with patients positioned in the Mayfield skull clamp showing lower mean levels of radiation than those in the headrest group (99 versus 131 cGy/cm2; P=0.003). Conclusions: Patient positioning using the Mayfield skull clamp may reduce required radiation exposure during ACDF procedures versus use of a padded headrest.

From the Oral Cavity to the Spine: Prevalence of Oral Cavity Infections in Patients with Pyogenic Spinal Infection.

Background incidence of pyogenic spinal infections has increased in recent years. In addition to treating the spinal infection, optimal care also includes identifying the source of the pyogenic spinal infection and the presence of other infections. The aim of this study is to elucidate the prevalence of oral cavity infection (OCI) within this patient cohort. Methods As part of a prospective study conducted from 2016 to 2021, the number of patients with dental infections was investigated by means of an orthopantomogram (OPG) and subsequent dental examination. Results The presence of an oral infection was investigated in 55 (47%) of 118 patients by an OPG, 29 (53%) of whom had a corresponding abnormality of the oral cavity. In addition to the spinal infection, patients with an oral cavity infection revealed an increased incidence of endocarditis, sepsis and brain abscess. A spinal epidural abscess, a multilevel affection of the infection, and an elevated CRP value were also found in patients with a co-existing oral cavity infection. Back pain assessed at admission and 3 months after surgery was also more pronounced in patients with an oral cavity infection. Neurological deficits were often present in patients with spinal and oral cavity infection. Conclusions The presence of an oral cavity infection has proven to be one of the important factors in the detection of the source of the pyogenic spinal infection. In addition, a pronounced spinal affection and frequent co-infections were seen in patients with an oral cavity infection.

Effectiveness of outpatient parenteral antimicrobial therapy (OPAT) for patients with cranial infection.

Objective: Outpatient parenteral antimicrobial therapy (OPAT) is a well-established and cost-effective method for improving the efficient use of healthcare resources. However, only a few centres in Germany perform it. Here we analysed OPAT for the treatment of patients with cranial infections in our neurosurgical department. Methods: This retrospective study analysed patients with cranial infections and the need for intravenous (i.v.) antimicrobial treatment between 2018 and 2021.All diagnosed intracranial infections were defined into two infection categories such as long-term antimicrobial treatment and short-term antimicrobial treatment. All included patients were discharged with a peripherally inserted central catheter (PICC) line. Prior to discharge, all patients received training in the safe administration of their medications via the PICC line. The duration of OPAT and the rate of readmission after OPAT were analysed. Results: We identified a total of 45 patients treated with OPAT for cranial infections. Intradural involvement was present in 40 cases (88.9%). The average length of hospital stay for this cohort after surgical treatment was 45 ± 15 days. 5 patients were treated for soft tissue/skin infection. Surgery was not required in this cohort. The mean hospital stay for this cohort was 8 ± 6 days. Gram-positive organisms were isolated in most cases (53.3%). The most common pathogens were Staphylococcus aureus followed by other Staphylococcus species. For all included patients, OPAT was performed after discharge for an average of 43.1 ± 14 days. There were five cases of readmission due to treatment failure. No serious adverse events or complications of OPAT were observed. Conclusion: OPAT enables better patient-centred healthcare close to home. The length of hospital stay can be reduced and adverse events due to prolonged hospitalisation can be avoided.

Increased Body Mass Index Correlates with Less Favorable Postoperative Outcomes After Hypoglossal Nerve Stimulation for Obstructive Sleep Apnea: A Retrospective Cohort Study.

OBJECTIVE: Obstructive sleep apnea is associated with high morbidity. Hypoglossal nerve stimulation (HNS) has become a novel (neuro-) surgical treatment strategy for obstructive sleep apnea, demonstrating good success rates. Beyond predefined inclusion and exclusion criteria, no precise data are available, enabling individual preoperative risk assessment. To improve preoperative risk stratification, this study analyzed individual patient factors that affect outcomes of HNS. METHODS: Fourteen patients treated with unilateral HNS were analyzed retrospectively. Assessed risk factors included: hypertension, diabetes mellitus, depression, smoking, alcohol consumption, body mass index (BMI), and disease duration. Treatment success was defined as a reduction in the postoperative apnea-hypopnea index (AHI) to ≤20 events/hour, with a relative reduction of at least 50% compared to baseline. RESULTS: A significant reduction in the postoperative apnea-hypopnea index was observed in all patients (P < 0.0001). BMI correlated significantly with postoperative AHI scores (95% confidence interval, 0.1519-0.8974; P = 0.018). Significant treatment success was observed in 50% of patients. Compared with the "Excellent Responder group," the "Responder group" demonstrated a significantly higher BMI (95% confidence interval, 1.174-6.226; P = 0.0078). Diabetes, hypertension, disease duration, smoking, depression, and alcohol consumption were not significantly associated with AHI reduction. CONCLUSIONS: Our findings suggest that BMI may be an independent risk factor for the response to HNS, with patients who had less benefit from therapy having significantly higher BMI than "Excellent Responders." Therefore, carefully selecting patients is crucial in obtaining optimal outcomes with HNS therapy, especially those with a high BMI.

The Beneficial Effect of Preoperative Exercise on Postoperative Clinical Outcome, Quality of Life and Return to Work after Microsurgical Resection of Spinal Meningiomas.

OBJECTIVE: While outcomes of surgical treatment for spinal meningiomas are well-described within the literature, factors affecting early return to work as well as long-term health related quality of life remain unclear. METHODS: In this retrospective study, patients with spinal meningioma and surgical treatment from two university-level neurosurgical institutions between 2008 and 2021 were analyzed. Time to return to work, physical activities and long-term health related quality of life (assessed by telephone interviews using the EQ-5D-5L health status measure and visual analogue scale (EQ VAS) were analyzed. RESULTS: We identified a total of 196 patients who underwent microsurgical resection of spinal meningioma between January 2008 and December 2021. Of those, 130 patients of working age were included and analyzed. The median follow-up time was 96 months. All included patients returned to work. The median time of return to work was 45 days for the whole cohort. Patients who preoperatively performed physical activity returned to work significantly earlier compared to patients who did not (p < 0.001). Furthermore, younger age (p = 0.033) and absence of obesity (p = 0.023) correlated significantly with earlier return to work. Significant differences were also observed in all 5 EQ-5D-5L dimensions between patients with and without preoperative physical activity. CONCLUSIONS: Despite the benign nature of spinal meningioma preoperative physical activity and physiological body weight are associated with favorable postoperative outcome, higher quality of life and early return to work.

Safety and feasibility of outpatient parenteral antimicrobial therapy for patients with spinal infection.

Outpatient parenteral antimicrobial therapy (OPAT) is a cost-effective method of administering intravenous antimicrobial therapy. Although OPAT is well established in the UK and US healthcare systems, few centres in Europe perform it. Here we analysed OPAT for the treatment of patients with spinal infections at our institution. In this retrospective study, patients with spinal infection who required intravenous (i.v.) antimicrobial treatment between 2018 and 2021 were analysed. The duration of short-term antimicrobial treatment for skin and soft tissue infections and complex infections requiring long-term antimicrobial treatment, such as spinal bone or joint infections, were analysed. All patients were discharged with a peripherally inserted central catheter (PICC) line. Prior to discharge, all patients received training in the safe administration of their medications via the PICC line. The duration of OPAT and the rate of readmission after OPAT were analysed. For this study a total of 52 patients who were treated via OPAT due to spinal infections were analyzed. In 35 cases (69.2%) complex spinal infection was reason for i.v. antimicrobial therapy. Surgery was required in 23 of these 35 patients (65.7%). The average hospital stay for these patients was 12 ± 6 days. The remaining 17 patients were treated for an infection of the soft tissue or the skin and hospital stay for these patients was on average 8 ± 4 days. Gram-positive organisms were isolated in 64.4%. Staphylococcus aureus followed by other Staphylococcus species, was the most common detected organism. After discharging i.v. antimicrobial treatment was given for an average of 20 ± 14 days. The duration of antimicrobial treatment for soft tissue was 10.8 ± 8 days, and for complex infections 25.1 ± 18 days. The mean follow-up was 21 ± 14 months. There was one case of readmission due to treatment failure. There were no difficulties encountered in implementing OPAT. OPAT is a feasible and effective option for delivering intravenous antimicrobial therapy to patients with spinal infections who can be managed without hospitalisation. OPAT offers patient-centred treatment at home while avoiding the risks associated with hospitalisation, with high levels of patient satisfaction.

Surgical management and clinical outcome of cervical, thoracic and thoracolumbar spinal tuberculosis in a middle-European adult population.

Spinal tuberculosis is due to globalization no longer a disease limited to developing nations. It remains in Germany a rarity and still a difficult diagnosis. Here we analyzed patients with spinal tuberculosis treated at our neurosurgical department. According to the infected anatomic segment, patients were assigned in one of three groups. Surgery was performed when neurological deficit due to mechanical compression, deformity, instability, severe pain, necrotic bone or failure to respond to anti-tuberculous treatment were observed. We identified 34 patients with spinal tuberculosis who underwent surgical treatment. In the cervical spinal tuberculosis group, there were 15 cases (46.9%) In most cases treatment consisted of spinal instrumentation. In the thoracic group, 10 cases (29.4%) were observed. The treatment was performed by dorsolateral spinal instrumentation. For the thoracolumbar group, 9 cases (26.4%) were observed. In most cases dorsolateral spinal instrumentation was performed. One patient in the first group and one patient in the third group relapsed after operation. A second surgery was necessary. Patients with chronic back pain, immigration background and/or neurological deficit spinal TB should be considered as a differential diagnosis. Combined surgical intervention and medical treatment is associated with a favorable outcome.

vHIT results with the synapsis system according to clinicians' dominant hand use.

BACKGROUND/OBJECTIVE: There exists limited information in the literature on dominant hand preference in relation with vHIT applications. The present study aimed to examine the relationship between the clinician's dominant use of right- or left-hand and vHIT results. METHODS: A Synapsys vHIT Ulmer device was used in the study. The tests were administered by 3 clinicians experienced in vHIT, 2 of whom were right-handed and 1 left-handed. The test was applied to the 94 participants three times, one week apart. RESULTS: In this study, the correlation between right-handed clinicians and left-handed clinicians was examined, and in all SCCs, namely RA, LA, RL, LL, RP and LP, a moderate positive significant correlation was found between right-handed1 and right-handed2, between right-handed1 and left-handed, and between right-handed2 and left-handed. CONCLUSIONS: In this study, these findings suggested that measures were reliable across test sessions regardless of hand dominancy (right or left). Based on the vHIT results we obtained with three different right- or left-handed clinicians, the clinician should evaluate the results according to the dominant side.

Cardiac effects of multisystem inflammatory syndrome in children: One-year follow-up.

AIM: Cardiovascular involvement is common among children with multisystem inflammatory syndrome (MIS-C) and can cause shock and death. In this study, we evaluated the early and long-term cardiac effects of MIS-C. METHODS: In this observational cohort study, we included all children treated for MIS-C from October 2020 to November 2021 in the Department of Paediatric Infectious Disease at Cukurova University School of Medicine Hospital. The patients underwent serial echocardiographical evaluation during hospitalisation and at 1, 3, 6 and 12 months after discharge. The patients were evaluated using Holter monitorisation between 4 and 6 months and using cardiac magnetic resonance imaging at 6 months and thereafter. RESULTS: Twenty-six patients diagnosed with MIS-C and with a median age of 84 months were included. Cardiac involvement was found in 19 (73.1%) patients. At initial echocardiographic evaluation, the mean ejection fraction value of the patients was 56.7% (range: 30-75). Coronary artery dilatation was detected in two (7.7%) patients, and mitral regurgitation persisted in only one patient by month 3. Treatment was started in two (7.7%) patients due to ventricular arrhythmia. Cardiac magnetic resonance imaging was performed in 13 (50%) patients at a median of 6 months (range: 5-9). The cardiac magnetic resonance imaging findings were consistent with possible interstitial fibrosis in two (7.7%) patients. CONCLUSION: Our results showed that cardiac involvement of patients improved rapidly with treatment, as indicated by previous studies. However, during the 1-year follow-up, frequent extraventricular systole was detected in two patients, one of whom initially did not show cardiac involvement. Moreover, possible interstitial fibrosis was detected in the cardiac magnetic resonance imaging (MRI) evaluation of two patients. In particular, we believe that these findings may be useful to evaluate critically ill paediatric patients and patients with severely low EF with cardiac MRI in their follow-up.

Reappraisal of Intracerebral Hemorrhages and Intracerebral Hemorrhage Grading Scale Score in Surgically and Medically Managed Cerebellar Intracerebral Hemorrhage.

BACKGROUND: As compared with supratentorial intracerebral hemorrhages (ICH), bleeds that occur within the cerebellum require special consideration given the nature of the posterior fossa. OBJECTIVE: To validate ICH and ICH grading scale (ICH-GS) scores in patients with cerebellar hemorrhage and examine the outcomes of patients managed surgically as compared with those who underwent conservative treatment. METHODS: This observational multicenter study included 475 patients with cerebellar hemorrhage from 9 different neurosurgical departments in Germany between 2005 and 2021. The prognostic accuracy of ICH and ICH-GS scores were calculated by the area under the curve of the receiver operating characteristic curves. Analyzed outcomes were the in-hospital mortality, mortality at 6 months, in-hospital outcome, and outcome at 6 months. RESULTS: Of 403 patients, 252 patients (62.5%) underwent surgical treatment and 151 patients (37.5%) conservative treatment. Both ICH and ICH-GS scores demonstrated good prognostic accuracy regarding both overall mortality and functional outcomes. In those patients presenting with severe cerebellar hemorrhages, ie, ICH score >3 and ICH-GS score >11, overall mortality was significantly lower in surgically treated patients. Mortality was significantly higher in those patients managed surgically who presented with ICH scores 3; in such patients, improved outcomes were noted when the hematoma was treated conservatively. CONCLUSION: ICH and ICH scores are useful tools for prediction of survival and outcome in patients with cerebellar ICH. Surgical management may be beneficial for those who present with severe cerebellar ICH as reflected by ICH scores >3, while conservative management seems reasonable in patients with lower ICH scores.

Evaluation of the Relation between Compliance with Mediterranean Diet and Quality of Life of Patients with Type 2 Diabetes.

The study was conducted to evaluate the relationship between compliance of Type 2 Diabetes patients with the Mediterranean Diet and their quality of life. A total of 200 patients admitted to TRNC Famagusta State Hospital Internal Medicine Clinic, diagnosed with Type 2 Diabetes, between the ages of 30-65 were included in the study. Patients filled out questionnaires that included data on demographic characteristics along with a 14-item MEDAS questionnaire, and SF-36 Quality of Life Scale. A total of 45% of patients were male, 55% female, mean age was 55 ± 8.28, and 65.6% of males and 49.1% of females complied moderately with the Mediterranean Diet (MEDAS score 6-9). According to the physical and mental indicator score, the quality of life of patients was moderate, and a strong relation was detected between gender and quality of life (p < 0.001). The scores of the quality of life of males were higher than those of females. Men and women who had moderate compliance with the Mediterranean Diet had higher physical function scores than those who had low compliance. The quality of life can be increased with regular training on the importance of dietary compliance because of the positive effects of the Mediterranean Diet on health.

Recurrence from the Spinal Region of the Patient Whose Treatment Was Completed with Liver and Lung Cystic Echinococcosis: A Rare Pediatric Case of Spinal Cystic Echinococcosis

Cystic echinococcosis is a parasitic disease caused by the Echinococcus tapeworm. The disease can often affect organs such as the liver and lungs, muscles, bones, kidneys, brain, and spleen. Spinal cystic echinococcosis has been reported very rarely in the literature. In this report; we present a pediatric case with spinal cystic echinococcosis, who was diagnosed with multiple cystic echinococcosis in the liver and lungs and was admitted with complaints of difficulty in walking and leg pain 1 year after the albendazole treatment, which he had been taking for 3.5 years. If a diagnosis of cystic echinococcosis was made in any organ, recurrences may occur in another organ at some time, even if the treatment is completed.

Evaluation of the efferent auditory system in COVID-19 adult patients.

BACKGROUND: The short- and long-term effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the medial olivocochlear reflex and outer hair cells in the cochlea remain largely unclear. AIMS: The aim of this study was to investigate the efferent auditory system effects in adult patients with COVID-19. MATERIALS AND METHODS: The study included 18-50 years old 44 volunteers: 26 individuals (52 ears) with COVID-19 in the study group and 18 healthy individuals (36 ears) in the control group. Otolaryngological examination, immitancemetric evaluation, distortion product otoacoustic emission (DPOAE), contralateral acoustic stimulation with DPOAE, audiometric evaluation, and high frequency audiometric evaluation were performed in all individuals participating in the study. RESULTS: In our study, patients with COVID-19 had significantly lower DPOAE results with or without broadband noise at only 6 kHz frequency and contralateral suppression results at all frequencies compared to healthy individuals. A statistically significant difference was found between the study and control groups according to whether the participants had a response in the high frequency audiometry at 12 and 16 kHz frequencies. CONCLUSIONS: COVID-19 affects many systems in the body. As a result of the findings obtained in the present study, it is shown that the auditory efferent system may also be affected.

Does Recurrence of Carpal Tunnel Syndrome (CTS) after Complete Division of the Transverse Ligament Really Exist?

The aim of this study was to evaluate whether recurrent carpal tunnel syndrome (CTS) after complete and sufficient division of the transverse ligament really exists. Another goal was to analyze the underlying reasons for recurrent CTS operated on in our department. Over an observation period of eleven years, 156 patients underwent surgical intervention due to CTS. The records of each patient were analyzed with respect to baseline data (age, gender, affected hand), as were clinical signs and symptoms pre- and postoperatively. To assess long-term results, standardized telephone interviews were performed using a structured questionnaire in which the patients were questioned about persisting symptoms, if any. Of the 156 patients, 128 underwent first surgical intervention due to CTS in our department. In long-term follow-up, two-thirds of these patients had no symptoms at all; one-third of the patients described mild persisting numbness. None of the patients experienced a recurrence of CTS. The 28 patients who received their first operation outside of our department were operated on for recurrent CTS. The cause of recurrence was incomplete division of the distal part of the transverse carpal ligament in all cases. The results suggest that recurrent CTS after complete and sufficient division of the transverse ligament is very unlikely.

Functional outcome and morbidity after microsurgical resection of spinal meningiomas.

OBJECTIVE: The aim of this study was to evaluate functional outcome, surgical morbidity, and factors that affect outcomes of surgically treated patients. METHODS: The authors retrospectively analyzed patients who underwent microsurgical resection for spinal meningiomas between 2009 and 2020. Patient data and potential variables were collected and evaluated consecutively. Functional outcomes were evaluated using univariate and multivariate analyses. RESULTS: A total of 119 patients underwent microsurgical resection of spinal meningioma within the study period. After a mean follow-up of 25.4 ± 37.1 months, the rates of overall complication, tumor recurrence, and poor functional outcome were 9.2%, 7.6%, and 5%, respectively. Age, sex, revision surgery, and tumor recurrence were identified as independent predictors of poor functional outcome. Obesity and surgeon's experience had an impact on the complication rate, whereas extent of resection and tumor calcification affected the rate of tumor recurrence. CONCLUSIONS: Microsurgical resection of spinal meningiomas remains safe. Nevertheless, some aspects, such as obesity and experience of the surgeons that result in a higher complication rate and ultimately affect clinical outcome, should be considered when performing surgery.

Normative values for semicircular canal function with the video head impulse test (vHIT) in healthy adolescents.

BACKGROUND: The vHIT device, which has a mechanism based on measuring the VOR gain, helps us to quickly evaluate six semicircular canals. AIMS/OBJECTIVES: The aim of this study was to establish normative values for semicircular canal function with the video head impulse test (vHIT) battery in normal adolescents. MATERIAL AND METHODS: 100 (50 females, 50 males) individuals aged 11-18 years, with a mean age of 14.99 years, were included in the study. RESULTS: As a result of the vHIT evaluations performed with vHIT Otometrics ICS Impulse A/S Taastrup, Denmark, the mean lateral canal vestibulo-ocular reflex (VOR) gain value was 0.96, the mean anterior canal VOR gain value was 0.89, and the mean posterior canal VOR gain value was 0.87, all of which were within the normal value range. CONCLUSION AND SIGNIFICANCE: While the VOR gain values and asymmetry values are within the normal value range and are similar to the literature, no statistically significant correlation was observed between these values and age. As a result, the vHIT battery is an easy, fast, and practical test method that can be used in adolescents.

Impact of Comorbidities and Frailty on Early Shunt Failure in Geriatric Patients With Normal Pressure Hydrocephalus.

Background/Aim: Older patients are considered to bear a higher perioperative risk. Since idiopathic normal pressure hydrocephalus (NPH) predominantly concerns older patients, identifying risk factors for early shunt failure for preoperative risk/benefit assessment is indispensable for indication and/or consultation of patients for ventriculoperitoneal shunting (VPS). Methods: We performed a retrospective study design, including data acquired from two university hospital neurosurgical institutions between 2012 and 2019. Overall, 211 consecutive patients with clinical/radiological signs for NPH who additionally showed alleviation of symptoms after lumbar cerebrospinal fluid (CSF) drainage, received VPS and were included for further analysis. Frailty was measured using the Clinical Frailty Scale (CFS). Main outcome was early shunt failure or post-operative complications within 30 days after initial VPS surgery. Results: The overall complication rate was 14%. Patient-related complications were observed in 13 patients (6%) and procedure-related complications in 16 patients (8%). Early post-operative complications resulted in a significantly prolonged length of hospital stay 6.9 ± 6.8 vs. 10.8 ± 11.8 days (p = 0.03). Diabetes mellitus with end-organ damage (OR 35.4, 95% CI 6.6 - 189.4, p < 0.0001) as well as preexisting Parkinson's disease were associated with early patient-related post-surgical complications after VPS for NPH. Conclusions: Patients comorbidities but not frailty were associated with early post-operative patient-related complications in patients suffering NPH. While frailty may deter patients from other (neurosurgical) procedures, VPS surgery might contribute to treating NPH in these patients at a tolerable risk.

The effect of subclinical hypothyroidism on body composition parameters in children.

BACKGROUND: It's known that overt hypothyroidism increases body fat content and weight. There's limited research about the effect of subclinical hypothyroidism (SH) on body composition in children and the effect of LT4 treatment. We aimed to evaluate body composition parameters in healthy subjects and in children with mild SH (MSH) and determine the effect of LT4 treatment. METHODS: Sixty-four healthy children and 32 children with MSH were included. Anthropometric measurements and hormonal parameters were evaluated. Body composition was evaluated using bioelectric impedance analysis (BIA). Patients were put on LT4 treatment. BIA was performed again after 12 months of therapy. RESULTS: There was no significant difference between the anthropometric parameters and basal metabolic rate of the healthy children and the MSH group. The percentage of trunk muscle mass (TMM) in the MSH group was lower than in the control group (P < .05). After 12 months of LT4 treatment, the percentage of total fat-free mass (FFM), TMM and trunk fat-free mass (TFFM) were increased and percentage of total body fat mass and trunk fat mass were decreased (P < .05). The difference between the percentage of TMM in the MSH group and control group was insignificant after LT4 treatment (P > .05). CONCLUSIONS: The percentage of TMM in children with MSH was found lower than healthy control group. After LT4 treatment, the percentage of the FFM, TMM and TFFM were increased and the difference between percentage of TMM in children with MSH and healthy controls was insignificant. Our data indicated that MSH might be associated with early changes in body composition parameters.

Academic output of German neurosurgical residents in 35 academic neurosurgery residency programs.

BACKGROUND: The scientific activity of neurosurgeons and neurosurgery residents as measured by bibliometric parameters is of increased interest. While data about academic output for neurosurgeons in the USA, the UK, and Canada have been published, no similar results for German neurosurgical residents exist. Within this study, we aim to evaluate the academic output of German neurosurgery residents in 35 academic residency programs. METHODS: Data for each resident were collected from the departmental websites, Pubmed, and Scopus. Further analyses evaluated the relationship between publication productivity, sex, and academic degree (Dr. med.). RESULTS: Data from 424 neurosurgery residents were analyzed. A total of 1222 publications were considered. A total of 355 (29%) of the 1222 publications were first-author publications. The average number of publications per resident was 2.9; the average h-index and m-quotient was 1.1 and 0.4, respectively. There was a statistically significant difference in academic output and h-index among neurosurgical residents with a doctoral degree compared with residents without such degree (5.3 vs. 1.3, p < 0.0001 and 2.0 vs. 0.5, p < 0.0001). CONCLUSION: This is the very first study evaluating the academic output of neurosurgical residents in academic neurosurgical departments in Germany.
