Abstract
INTRODUCTION A common technique for the treatment of medial patellar luxation is the lateral transposition of the tibial tuberosity. Two variations of a new surgical method with a retention plate and fixation with a wire or a security plate, were tested against each other and against the existing fixation with Kirschner wires and a tension band by the number of reoperations. The new method using a retention plate and security plate showed the lowest rate of reoperations (5 %), followed by the new technique using retention plate and wire (14 %) and the existing fixation with Kirschner wires and a tension band (34 %). A possible explanation for the good result of the new method can be the fixation of the implants on the medial side of the tibia and the non-use of Kirschner wires.

Changes in injury patterns, injury severity and hospital mortality in motorized vehicle accidents: a retrospective, cross-sectional, multicenter study with 19,225 cases derived from the TraumaRegister DGU ®. Eur J Trauma Emerg Surg 2023; 49:1917-1925. [PMID: 36890307 PMCID: PMC9994772 DOI: 10.1007/s00068-023-02257-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 02/24/2023] [Indexed: 03/10/2023]
Abstract
PURPOSE In the last 20 years, the number of fatalities due to road traffic accidents (RTA) in Germany has steadily decreased from 7503 to 2724 per year. Due to legal regulations, educational measures and the continuous development of safety technology the number of severe traumatic injuries and injury patterns are most likely to change. The aim of the study was to analyse severely injured motorcyclists (MC) and car occupants (CO) that were involved in RTAs in the last 15 years and investigate the development and changes of injury patterns, injury severity and hospital mortality. METHODS We retrospectively evaluated data from the TraumaRegister DGU® (TR-DGU) considering all RTA-related injured MCs and COs (n = 19,225) that were registered in the TR-DGU from 2006 to 2020 with a primary admission to a trauma center with continuous participation (14 of 15 years) in the TR-DGU, an Injury Severity Score (ISS) ≥ 16 and aged between 16 and 79 years. The observation period was divided into three 5-year interval subgroups for further analysis. RESULTS The mean age increased by 6.9 years and the ratio of severely injured MCs to COs changed from 1:1.92 to 1:1.45. COs were in 65.8% male and more often severely injured in the age groups under 30, while the majority of severely injured MCs were in the age group around 50 years and in 90.1% male. The ISS (- 3.1 points) as well as the mortality of both groups (CO: 14.4% vs. 11.8%; MC: 13.2% vs. 10.2%) steadily decreased over time. Nevertheless, the standardized mortality ratio (SMR) hardly changed and stayed < 1. Regarding the injury patterns, the greatest decline of injuries with AIS 3 + were to the head (CO: - 11.3%; MC: - 7.1%), in addition, a decrease of injuries to extremities (CO: - 1.5%; MC: - 3.3%), to the abdomen (CO: - 2.6%; MC: - 3.6%), to the pelvis in COs (- 4.7%) and to the spine (CO: + 0.1%; MC: - 2.4%) were observed. Thoracic injuries increased in both groups (CO: + 1.6%; MC: + 3.2%) and, furthermore, pelvic injuries in MCs (+ 1.7%). Another finding was the increase of the utilization of whole body CTs from 76.6 to 95.15%. CONCLUSION The severity of injuries and their incidence, especially head injuries, have decreased over the years and seem to contribute to a decreasing hospital mortality of polytraumatized MCs and COs injured in traffic accidents. Young drivers and an increasing number of seniors are the age groups at risk and require special attention and treatment.

Analysis of the primary utilization of videolaryngoscopy in prehospital emergency care in Germany. DIE ANAESTHESIOLOGIE 2023; 72:245-252. [PMID: 36602556 DOI: 10.1007/s00101-022-01247-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 10/19/2022] [Accepted: 12/08/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND In 2019, the German prehospital airway management guidelines were published. One of the recommendations was the primary utilization of videolaryngoscopy (VL) for every prehospital endotracheal intubation (phETI). Guideline compliance is extremely important in emergency medicine as non-compliance in the worst-case scenario leads to death. The study aims to quantify guideline compliance among emergency medical service (EMS) physicians and, subsequently to analyze subgroups influencing compliance. MATERIAL AND METHODS An online survey was developed and distributed as a hyperlink via email to all medical directors of EMS (n = 155) and the three main operators of helicopter emergency medical services (HEMS) in Germany. The survey was online from August 1st 2021 until October 3rd 2021. The primary outcome measure was the primary VL utilization. Data were evaluated descriptively. A multivariate regression analysis was used to determine associations between the primary VL utilization and age, sex, educational level, specialization, phETI per year, operating field, VL device type, and guideline knowledge. RESULTS The analysis included 698 EMS physicians. More than 55% of the EMS physicians do not primarily use a videolaryngoscope for phETI. Multivariate regression analysis showed a significantly higher compliance if the devices C‑MAC® or McGrath® were on board, guidelines were known or EMS physicians were female. Age, educational level, specialization or prehospital intubation experience had no significant impact. CONCLUSION The study shows non-compliance with prehospital airway management guidelines in Germany. The guideline recommendation is based on scientific evidence but is not yet generally accepted by all EMS physicians. Videolaryngoscope device type and sex seem to influence the primary VL utilization. Training for EMS physicians must be extended and individual prehospital airway management should be reconsidered by every EMS physician.

Abstract
INTRODUCTION The objective of this study was to test a method for determining the width of the tibial tuberosity advancement (TTA) cage without the need for extension of the stifle joint, while producing preoperative radiographs. TTA cage size was determined by applying 4 different methods using radiograph images in mediolateral direction of fully extended stifles of dogs (n=43), with and without naturally occurring cranial cruciate ligament disease: parallel shift (PS) method, common tangent (CT) method, «2,1» method (cage size = 2,1 × tibia plateau length - tibial tuberosity width), and margo cranialis (MC) method (cage size = length of MC/6*1,75). Two new methods, «2,1», and MC were compared to the existing CT and PS methods. All 4 methods resulted in reliable cage sizes. Intraclass correlation coefficients showed an excellent reliability of the CT and PS to the «2,1» method and a good reliability in regards to the MC method. In conclusion, TTA cage size of the tibia anatomy alone can be determined on radiographs without the need of full extension of the stifle joint. Based on the results, two different methods of cage size measurement are recommended in order to increase diagnostic accuracy and to prevent the insertion of suboptimal cages.

Abstract
INTRODUCTION Monteggia fractures are rare traumatic injuries in cats and dogs. Ulna repair is mostly achieved by plates. Stable radial head fixation however is challenging. Temporary position screws have to be removed due to rotation forces in the elbow joint causing screw loosening. We present a novel and simple method using a sling technique, which holds the radial head in its physiological position and allows normal elbow movement.

Abstract
PURPOSE Pilot studies of combined therapies treating benign nodular goiters reported promising results. The aim of this study was to investigate the effectiveness of combined microwave ablation (MWA) and radioiodine therapy (RIT) with a special focus on thyroid function at the 3-month follow-up. MATERIALS AND METHODS 15 patients (median age: 55 years) with a large goiter and benign thyroid nodules or Graves' disease were treated with the combined therapy. Serum levels of triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), thyroglobuline (Tg) and, additionally, antibody levels against thyroglobulin (TgAb), thyrotropin receptors (TRAb) and thyroid peroxidase (TPOAb) were measured at enrollment, post MWA and at the 3-month follow-up (3MFU). Furthermore, the goiter volume, I-131 dose and hospitalization time were analyzed to evaluate effectiveness. MWA was operated under local anesthesia with a system working in a wavelength field of 902 to 928 MHz. RESULTS TSH, T4, T3 and Tg did not change at 3MFU, except for in two patients in whom the initial TSH levels improved to normal thyroid functioning levels at follow-up. One of the patients developed a high TRAb-level that receded back into the normal range. At 3MFU, the combined therapy showed a mean thyroid volume reduction of 26.4 ml ± 7.9 ml (30.5 % ± 4.6 % (p < 0.05)). By utilizing the combined therapy, administered activity could be reduced by 26.6 % ± 4.8 % (p < 0.05) and hospitalization time by 30.9 % ± 19.9 % (p < 0.05). CONCLUSION The data confirmed the effectiveness of the combination of MWA with RIT. The combined therapy is an innovative and conservative approach and could become a safe alternative to surgery for the treatment of very large benign nodular goiters. Due to the short follow-up and the limited number of patients, further studies will be necessary. KEY POINTS • The combined therapy shows a significant volume reduction in benign nodular goiters. • Initial MWA improves the RIT results by reducing the required therapy activity. • Thyroid function is preserved after combined therapy.

Abstract
For some time Norwich terriers have been known to suffer from respiratory problems. In order to assign this weakness to a pathophysiology, 23 terriers were examined clinically, with laryngoscope and with rhinomanometry. In addition their skulls were dimensioned on radiographs. Widened nostrils, overlong soft palates and the everted laryngeal pouches were consistent with brachycephalic syndrome. Resistance values in the nasal passage corresponded to the appearance in brachycephalic dogs. Skull measurements gave inconsistent results, because length to width ratios and craniofacial angles denoted mesaticephaly, whereas the facial to cranial length ratios (S-index = 0.65) lay in the brachycephalic sector. It can be concluded, that the Norwich terrier breed is in transition towards brachycephaly with some individual dogs already suffering from the brachycephalic syndrome. Breeders are requested to introduce necessary counter measures.

Abstract
The purpose of this study was to determine if treatment strategy had a significant effect on the occurrence of physiological changes consistent with metabolic syndrome and/or type 2 diabetes in patients using atypical antipsychotic medications. The four variables assessed were: weight gain, fasting blood sugar, triglycerides and cholesterol. The two strategies compared were (1) evidence-based practice, derived from the Texas Medication Algorithm Project, and (2) practitioner preference. A retrospective chart review was performed on patients diagnosed with a chronic psychiatric disorder being treated with atypical antipsychotics. The dates of the reviewed records were from 1 January 2008 to 31 December 2008. The sample of patients totaled 113. Statistical analysis included logistic regression for each of the four variables assessed. The use of evidence-based practice guidelines was found to have strong positive effects on two of the four variables assessed. Further studies need to be conducted to include medications being taken to lower lipids and blood sugar. Overall, the use of evidence-based practice guidelines has a positive effect on weight, triglycerides and cholesterol. It is important that patients be closely monitored and changes made in a timely manner to minimize adverse effects of atypical antipsychotics.

Abstract
INTRODUCTION According to the guidelines for cancer of the skin in the head and neck region of the German association of Otolaryngology, Head and Neck surgery squamous cell carcinoma (SCC) of the pinna are classified by using the current TNM system of skin cancer. As soon as cartilage is infiltrated, irrespective of other criteria like tumour size, SCC of the thin skin of the pinna are classified as T4 category. As therapy considerably depends on the TNM stage a review of the prognostic value of cartilage infiltration as well as other histological criteria seems to be justified. METHODS Medical records of all patients (n = 36) being operated for SCC of the pinna between August 1988 and January 2004 at our department were retrospectively analysed with regard to a statistical correlation of histological criteria, cervical lymph node metastases and prognosis. RESULTS In 36 cases a histological re-evaluation could be performed on the original tumour samples (34 male symbol : 2 female symbol; average age was 76 years, with an age interval of 54 - 99 years). 26 SCC cases were smaller than 2 cm, 8 cases between 2 and 5 cm and 2 cases bigger than 5 cm of size. 36 % of SCC cases had infiltration of the auricular cartilage. Statistical analysis did not show a statistical correlation of either cartilage infiltration, tumour size bigger than 2 cm or 1 cm, tumour grading and tumour depth with regard to lymph node metastases. DISCUSSION According to our results, cartilage infiltration as single criterion of inclusion into a T4 category should be analysed cautiously. The anatomical peculiarity of the pinna where cartilage lies directly beneath very thin skin should be taken into account. A survey of a bigger group of patients e. g. as a multicenter study would be desirable for such a rare malignancy.

Abstract
In 32 male dogs colopexy, vasopexy, cystopexy and castration was performed for the treatment of perineal hernia. Recurrence rate in this study is 22%, what is comparable to other studies using different methods. The degree of severity and the number of complications is lower with this technique than with others. Enlargement of the prostate was evident in 59% and bladder retroflexion in 22% of the dogs. A celiotomy allows to recognize, assess, reduce and fix displaced organs which is not possible by using other methods. The aim is to regain the tubular structure of the ampulla recti and to fix prostate and bladder cranioventrally to the pelvic entrance. The castration performed at the same time causes the prostate gland to atrophy within 2-3 weeks, what makes the pelvic entrance even wider and the dogs return to normal defecation.

Abstract
An eight-month-old female rottweiler was presented with a history of intermittent lameness of the right hindlimb of 4 weeks duration. Radiographs showed a fragmentation in two plantar sesamoid bones of the metatarsophalangeal joint. Based on these clinical and radiographic signs sesamoid disease of the 2nd and 7th sesamoid bone in the right hindpaw was diagnosed. The fragmented sesamoids were surgically removed and histologically examined. The treatment was successful and the dog became lamnessfree. Additional radiographs showed fragmentations of sesamoid bones VII of both the forepaws, but they did not cause any lameness.

Abstract
Molecular analysis of biological specimens usually requires extraction of high-molecular weight DNA free of foreign DNA contaminants. DNA was extracted from black flies at different life stages that had been preserved by 4 methods: larvae and adults in ethanol, larvae in Carnoy's solution, adults on card-points, and adults hand-swatted and sun-dried. Using specific primers for the mitochondrial ND4 gene, a 257-bp amplicon was obtained from specimens preserved by ethanol, card-point mounting, and sun-drying. Successful amplification often required DNA dilutions > or = 1:20 (< 1-10 ng). DNA from specimens preserved in Carnoy's solution (ethanol: acetic acid, 3:1) yielded degraded DNA, resulting in fewer successful amplications. Parasitic nematodes and, to a lesser extent, gut contents resulted in extra products when amplified with randomly amplified polymorphic DNA (RAPD) primers. Sufficient DNA was extracted from the head of a larva for a successful polymerase chain reaction (PCR), eliminating the need to remove the contaminating gut and parasites.

Abstract
Twenty cases with patellar luxation in dogs and cats, in which a sulcoplasty and cranialisation of the tuberositas tibiae were performed, were investigated and reviewed retrospectively. Twelve knees were available for follow-up after a mean period of 15 months. Clinical scoring of patients showed eight with no lameness, three with an occasional weightbearing lameness, and one with a frequent weightbearing lameness. The patella was stable and could not be luxated in ten out of twelve cases. Degenerative joint disease was slightly progressive in the postoperative period. It did not impair the outcome of the procedure.

Abstract
Type II B arylsulfatases are known to inactivate slow reacting substance (SRS), but the mechanism is unclear. In the present study, ordinary commercial preparations of Sigma limpet arylsulfatase largely inactivated the glutathionyl and cysteinyl-glycyl forms of SRS, but the cysteinyl form of SRS was largely resistant to the enzyme. Evidence is presented which established that a major mechanism for the inactivation of the glutathionyl and cysteinyl-glycyl SRS types, at least by the particular enzyme preparations we have studied, involves cleavage of the glycine moiety from the sulfur containing side chain. This was confirmed by digestion studies with glutathione itself. In addition, there is some evidence to indicate that the enzyme may destabilize the double bond structure of the SRS molecule, contributing to the overall inactivation.
