Interscalene anesthesia for shoulder arthroscopy in a community-sized military hospital

The first 100 consecutive shoulder arthroscopic procedures performed under interscalene anesthesia at a small community-sized military hospital are the basis of this report. This method of anesthesia was compared with 100 shoulder arthroscopies performed in a previous 2-year time period under general anesthesia. A variety of arthroscopic and subsequent open reconstructive procedures about the shoulder were performed using both techniques. Using the interscalene method, 87 regional blocks were entirely successful. Thirteen patients required conversion to general anesthesia for adequate pain control; however, 4 of these had a complete block in the recovery room and required no postoperative narcotics. Seven patients required supplementation with local anesthetic when an open procedure became necessary. There were no major complications. Minor complications included 5 patients with transient Horner's syndrome, 4 patients who experienced anxiety, which was controlled with sedation, and 3 with nausea or pruritus. Interscalene anesthesia provided excellent intraoperative and postoperative analgesia with low morbidity. On a subsequent questionnaire, all patients with a successful block reported that they were extremely satisfied with their experience. Ten patients who had previous shoulder surgery under general anesthesia preferred the interscalene method. In summary, interscalene anesthesia proved to be an excellent method of anesthesia for shoulder arthroscopy. The technique is reproducible within the resources available in most community-level hospitals.     

Integration of geriatric assessment into clinical oncology practice: A scoping review

Sixty percent of newly diagnosed cancers occur in older adults and more complex planning is required to sustain quality care for older populations. Individualized care incorporating geriatric assessment can predict early mortality and treatment toxicity for older cancer patients. We mapped and summarized the available evidence on the integration of geriatric assessment into clinical oncology practice, and ascertained which domains have been implemented. We systematically searched bibliographic databases and trial registries for reports of clinical studies, clinical practice guidelines, systematic and non-systematic reviews, and grey literature published in English. We gathered data on study characteristics, geriatric domains and strategies evaluated, and relevant study objectives and findings. From a total of 10,124 identified citations, 38 articles met our eligibility criteria, 3 of which were clinical practice guidelines. Nearly half of these articles came from the United States. Domains of the geriatric assessment implemented in studies ranged from 1 to 12, with varied combinations. We identified 27 studies on strategies for implementing geriatric assessment and 24 studies on feasibility of implementing geriatric assessment, into clinical oncology practice. We also identified 3 main geriatric assessment models: 2 from the United States and 1 from Australia. Furthermore, we identified 2 reviews that reported varied components of geriatric assessment models. There is increasingly robust evidence to implement formal geriatric assessment in oncology practice. There remains a great deal of variation in the tools recommended to address each of the domains in a geriatric assessment, with only 1 guideline (American Society of Clinical Oncology guideline) settling on a specific best practice.Protocol registration: Open Science Framework osf.io/mec93.     

Renal Transplantation Under Prophylactic Eculizumab in Atypical Hemolytic Uremic Syndrome With CFH/CFHR1 Hybrid Protein

We report the first observation of successful kidney transplantation under pre‐emptive eculizumab treatment in a 7‐year‐old boy with atypical hemolytic uremic syndrome (aHUS) and a known hybrid CFH/CFHR1 gene, who was dependent on plasma therapy during the 3‐year dialysis period. The hybrid CFH/CFHR1 protein has an altered C3b/C3d binding, is incapable to protect cells from complement attack and is directly implicated in aHUS pathogenesis. There was no evidence of recurrence during the first 16‐month follow‐up period. We conclude that eculizumab alone, without plasma therapy (plasma infusion and/or plasma exchange), is sufficient to prevent recurrence of aHUS and to maintain long‐term graft function.     

Unusual electrocardiographic evidence of metastatic cardiac tumor resembling atrial infarction

A case of metastatic carcinoma of the left atrium is described. The correct antemortem diagnosis was made on the basis of electrocardiographic changes resembling atrial infarction. These included deformed P waves, deviation of the P-Ta segments and atrial arrhythmias.     

Corpus callosum and limbic system: neuroanatomic MR evaluation of developmental anomalies

Agenesis of the corpus callosum is a complex malformation of the brain that has been associated with varying degrees of limbic system maldevelopment. We retrospectively reviewed the records of 11 patients with callosal agenesis (seven total, four partial) who underwent magnetic resonance (MR) imaging, with particular attention to the associated malformations of the limbic system. Comparison was made with selected images from MR examinations of healthy volunteers and with necropsy specimens from other patients with callosal agenesis. Ten of 11 patients demonstrated limbic anomalies (severe motion artifact precluded evaluation of these structures in one patient). MR depicted not only the abnormalities intrinsic to callosal agenesis but also the frequently associated malformations of the limbic system.     

Effect of parental age on fertilization and pregnancy characteristics in couples treated by intracytoplasmic sperm injection

The purpose of this study was to investigate any influence of maternal and/or paternal age on gamete characteristics and pregnancy outcomes in intracytoplasmic sperm injection (ICSI) cycles. In all, 821 consecutive ICSI cases were analysed retrospectively. While a significant linear decline in semen volume was detected, no significant differences in the concentration, motility or morphology of the spermatozoa were found with paternal ageing. A significant decline in the number of oocytes retrieved and the number of mature oocytes obtained was found with advancing maternal age. An increase in the occurrence of digyny was noted with parental ageing, while no difference in single or bipronuclear fertilization was found. Older women had a decreased incidence of single pronucleus formation and an increase in digyny, but no significant difference in the percentage of oocytes that underwent two-pronuclear fertilization was detected with regard to maternal ageing. Pregnancy outcomes were not influenced by the age of the male partner, while a strong negative correlation was found with maternal ageing. To better analyse male partner ageing as a factor affecting pregnancy outcome, we analysed a subgroup of patients with a female partner aged <35 years who underwent ICSI. No paternal influence on ICSI pregnancy outcome was found in this subgroup of patients. We conclude that the influence on pregnancy outcome after ICSI is related mostly to maternal and not paternal age.
