The Importance of the Length of the Limbs for Gastric Bypass Patients—An Evidence-based Review

The ideal length of the gastric bypass limbs is debated. Recent evidence suggests that standard limb lengths used today have a limited impact on patient weight loss. Our objective was to appraise critically the available evidence on the influence of the length of gastric bypass limbs on weight loss outcomes. We systematically reviewed MEDLINE, the Cochrane database of evidence-based reviews, and the Database of Abstracts of Reviews of Effects for articles reporting the effect of gastric bypass length on outcomes published between 1987 and 2009. Four randomized controlled trials and several retrospective studies were identified and reviewed. Longer Roux limb lengths (at least 150 cm) were associated with a very modest weight loss advantage in the short term in superobese patients. No significant impact of alimentary limb length on weight loss for patients with body mass index (BMI) <50 was seen. When the length of the common channel approaches 100 cm, a significant impact on weight loss is observed. The currently available literature supports the notion that a longer Roux limb (at least 150 cm) may be associated with a very modest weight loss advantage in the short term in superobese patients but has no significant impact on patients with BMI ≤50. To achieve weight loss benefit due to malabsorption, bariatric surgeons should focus on the length of the common channel rather than the alimentary or biliopancreatic limbs when constructing a gastric bypass especially in the superobese population where failure rates after conventional gastric bypass are higher.     

Dialysis and Pregnancy—A Case Report and Review of the Literature

We report on a patient with an eight-year history on maintenance hemodialysis treatment without residual renal function in whom pregnancy was successfully managed through to the 29th week. During this time, under carefully modified dialysis treatment, the nephrologic course, as well as materno-fetal flow relationships were unremarkable. Fetal development was appropriate for gestational age. However, pregnancy was complicated by polyhydramnios, which necessitated i.v. tocolysis. In the 28 + 6th week of gestation, cesarean section was performed because of an antibiotic-resistant fever of unclear origin which ceased within two days of delivery Although the postnatal course of the adequately developed baby was complicated by the respiratory distress syndrome, normal development continued.

We emphasize that the intensive interdisciplinary cooperation of ne-phrologists and obstetricians is imperative for the successful manngement of pregnancy under these conditions. In these pregnancies, the main fetal problems consist of premature labor because of polyhydramnios, preterm delivery, intrauterine growth retardation and stillbirth. The mother is threatened by the development of superimposed pre-eclampsia, left ventricular failure because of volume overload and progressive anemia. In order to maintain a well-balanced homeostasis, intensification of dialysis therapy by an increase in frequency and duration is the most important therapeutic approach. Accurate fetal monitoring including frequent examination of the feto-maternal circulation by Dopplersonography as well as attentive surveillance of the mother is required to recognize the above mentioned complications.     

☆Diagnostic and therapeutic injections of the foot and ankle—An overview

Foot and ankle injections are useful diagnostic and therapeutic tools, particularly when the pain etiology is uncertain. A variety of foot and ankle injuries and pathologies, including degenerative joint disease, plantar fasciitis and different tendinopathies are amenable to injections. Understanding the foot and ankle anatomical landmarks, a thorough physical exam and knowledge of the different injection techniques is key for a successful approach to different pathologies. The objective of this study is to review the use of foot and ankle injections in the orthopaedic literature, present the readers with the senior author's experience and provide a comprehensive clinical guideline to the most common foot and ankle diagnostic and therapeutic injections.     

Osteoporosis Associated with Epilepsy and the Use of Anti-Epileptics—a Review

The increased rate of fractures associated with epilepsy has been long recognised but remains incompletely understood. Study quality and study results have varied, with some but not all studies showing bone diseases including osteoporosis and/or osteomalacia, and a high prevalence of vitamin D insufficiency and deficiency are also noted. Falls risk can also be higher in patients with epilepsy taking anti-epileptic medications, potentially leading to fracture. Larger research collaborations are recommended to further advance understanding in this field, particularly to examine underlying genetic and pharmacogenomic associations of epilepsy and anti-epileptic medication usage and its association with bone diseases and fractures, as well as further investigation into optimal management of bone health in epilepsy.     

Procidentia: The chaffin vaginal subtotal hysterectomy for the cure of fourth degree prolapse—Review of technic and results

We have reviewed our results with the “Chaffin vaginal subtotal” operation for prolapse. An analysis appears to disclose that results are superior to any other type of surgery. This technic is again discussed. The explanation and reason are given for the better results. The operation is simple and more easily performed than other vaginal plastic procedures. It is applicable to all ages as it restores and maintains the normal vagina.     

Study of the response of the urinary bladder to stimulation of the cervix uteri and clitoris — The ‘genitovesical reflex’: An experimental study

There is a debate as to whether, during the sexual act, some women eject a fluid that could be urine. As a part of investigation into this subject, the effect of stimulation of the clitoris and cervix on urinary bladder pressure and external urethral sphincter (EUS) activity was studied in 12 bitches. The clitoris and cervix were stimulated both electrically and mechanically. Upon clitoral or cervical stimulation, the vesical pressure dropped (P<0.05) and the EMG activity of EUS increased; action potentials increased and latency decreased when the stimulation frequency increased. No fluid came out of the external urethral orifice or the vagina. Stimulation of the anesthetized clitoris and cervix effected no vesical pressure or EUS response. These results were reproducible. The study has shown that on clitoral and cervical stimulation, which closely simulates the conditions during coitus, the bladder neck was firmly closed by EUS contraction, whereas the vesical detrusor was relaxed. A constant and reproducible reflex relationship existed between the clitoris, or the cervix, and the urinary bladder, which the author calls the genitovesical reflex and which probably acts to prevent urinary leak during coitus. The genitovesical reflex may prove to be of diagnostic significance in genitourinary disorders.Editorial Comment: This is a very interesting study on the effects of clitoral and cervical stimulation on the bladder and external urethral sphincter. It points out that in the normal female dog (and possibly in the normal female patient) cervical and clitoral stimulation, as might occur with coitus, should bring about relaxation of the bladder and an increase in the tone of the external urethral sphincter to prevent urine loss. I think this points out that urine loss associated with orgasm should be considered pathologic, and may be a symptom of detrusor instability. The pathologic association of urinary incontinence with orgasm and detrusor instability was pointed out by Hilton in 1988 and Khan in 1988. This paper complements these studies by demonstrating a reflex in the female dog which produces bladder relaxation and external urethral sphincter tone increase during coital-type stimulation.     

Ulnar Nerve Innervation of the Triceps Muscle: Real or Apparent? An Anatomic Study

Background

Since the 18th century, the existence of ulnar nerve innervation of the medial head of the triceps brachii muscle has been controversial. The evidence for or against such innervation has been based on macroscopic dissection, an unsuitable method for studying intraneural topography or intramuscular branching. The study of smaller specimens (embryos or fetuses) by means of serial histologic sections may resolve the controversy.

Questions/Purposes

Using fetal specimens and histology we determined the contributions of the ulnar and radial nerves to innervation of the triceps brachii muscle.

Methods

We histologically examined 15 embryonic and fetal arms. Radial nerve branches obtained from six adult arms were analyzed immunohistochemically to determine motor fiber content.

Results

The medial head of the triceps brachii muscle was always innervated by the radial nerve (ulnar collateral branch). The branches seeming to leave the ulnar nerve at elbow level were the continuation of the radial nerve that had joined the ulnar nerve sheath via a connection in the axillary region. Immunohistochemistry revealed motor and nonmotor fibers in this radial nerve branch.

Conclusions

A connection between the radial and ulnar nerves sometimes may exist, resulting in an apparent ulnar nerve origin of muscular branches to the medial head of the triceps, even though in all our specimens the fibers could be traced back to the radial nerve.

Clinical Relevance

Before performing or suggesting new muscle and nerve transpositions using this apparent ulnar innervation, the real origin should be confirmed to avoid failure.     

The Historical Narrative: Tales of Professionalism?

The historical narrative is a story told to illustrate a point, however subconsciously. The "giants" of obstetric anesthesia -- Simpson, Snow, Apgar -- and countless other less well-known physicians all contributed to the history of obstetric anesthesia. We remember them by retelling this history to illustrate elements of professionalism and how we as a profession wish to act. The Physician Charter is an excellent first approximation of a workable definition of this quality, which can and does change over time. By using the three principles and 10 professional responsibilities as a template, the past comes alive as a teaching method to each and every obstetric anesthesiologist.     

Evaluation of the Effects of Laparotomy and Laparoscopy on the Immune System in Intra-Abdominal Sepsis—A Review

This review portrays the most common experimental models of intra-abdominal sepsis. Additionally, it outlines the facts that distinguish laparotomy from laparoscopy, in respect to the immune response, when comparing these two techniques in experimental models of intra-abdominal sepsis. It describes the consequences of pneumoperitoneum and trauma produced by laparoscopy or laparotomy, respectively, on bacterial translocation and immunity. Furthermore, we report the few efforts that have been made in clinical settings, where surgeons have attempted to utilize laparoscopy as a therapeutic module when treating peritonitis or sepsis of abdominal origin. Certainly there is a need for more research in order to fortify the role of pneumoperitoneum in sepsis of abdominal origin. It seems that minimally invasive surgery will inevitably gain acceptance by surgeons, as evidence points that by inflicting less trauma the healing response is expected to be more efficient, especially in septic patients.     

The prehospital management of hypothermia — An up-to-date overview

BackgroundAccidental hypothermia concerns a body core temperature of less than 35 °C without a primary defect in the thermoregulatory system. It is a serious threat to prehospital patients and especially injured patients, since it can induce a vicious cycle of the synergistic effects of hypothermia, acidosis and coagulopathy; referred to as the trauma triad of death. To prevent or manage deterioration of a cold patient, treatment of hypothermia should ideally begin prehospital. Little effort has been made to integrate existent literature about prehospital temperature management. The aim of this study is to provide an up-to-date systematic overview of the currently available treatment modalities and their effectiveness for prehospital hypothermia management.Data sourcesDatabases PubMed, EMbase and MEDLINE were searched using the terms: “hypothermia”, “accidental hypothermia”, “Emergency Medical Services” and “prehospital”. Articles with publications dates up to October 2017 were included and selected by the authors based on relevance.ResultsThe literature search produced 903 articles, out of which 51 focused on passive insulation and/or active heating. The most effective insulation systems combined insulation with a vapor barrier. Active external rewarming interventions include chemical, electrical and charcoal-burning heat packs; chemical or electrical heated blankets; and forced air warming. Mildly hypothermic patients, with significant endogenous heat production from shivering, will likely be able to rewarm themselves with only insulation and a vapor barrier, although active warming will still provide comfort and an energy-saving benefit. For colder, non-shivering patients, the addition of active warming is indicated as a non-shivering patient will not rewarm spontaneously. All intravenous fluids must be reliably warmed before infusion.ConclusionAlthough it is now accepted that prehospital warming is safe and advantageous, especially for a non-shivering hypothermic patient, this review reveals that no insulation/heating combinations stand significantly above all the others. However, modern designs of hypothermia wraps have shown promise and battery-powered inline fluid warmers are practical devices to warm intravenous fluids prior to infusion. Future research in this field is necessary to assess the effectiveness expressed in patient outcomes.     

Nonarterialized Venous Replantation of Part of Amputated Thumb—A Case Report and Review of the Literature

Since the first successful replantation of a human thumb reported by Komatsu and Tamai in 1968, thousands of severed digits and body parts have been successfully salvaged. Restoration of anatomic form and function are the goals of replantation after traumatic tissue amputation. Regardless of anatomic location, methods include microsurgical replantation and nonmicrosurgical replantation, such as composite graft techniques. Numerous techniques to maximize tissue survival after revascularization have been described, including “pocket procedures” to salvage composite grafts, interposition vein grafts, and medicinal leeches to name a few. Artery-to-venous anastomoses have been performed with successful “arterialization” of the distal venous system in fingertip replantation. Although there is documented survival of free venous cutaneous flaps, to our knowledge this is the first report of a replanted composite body part (bone, tendon, soft tissues, and skin) utilizing exclusively multiple, microvascular, nonarterialized venous–venous anastomoses. We present a patient with an isolated band saw fillet amputation to the back of the thumb at the metacarpal–phalangeal joint region, resulting in a composite graft composed of bone, tendon, soft tissue, and skin. The hand wound provided no viable regional arterial inflow source, but there were multiple good caliber superficial veins present. The amputated tissues were replanted and revascularized by using only venous blood flow. The replanted part survival was 100% with excellent function of the digit. We conclude that a hand composite body part involving bone, tendon, soft tissues, and skin can survive replantation with a strict venous blood supply if sufficient good caliber, microvascular, venous–venous anastomoses are performed, granted that arterial inflow options are not available. This is an isolated case, yet introduces a new way of thinking regarding tissue replantation.
