Ultrasound-Guided Peri-Lymphatic and Peri-Neural Corticosteroid Injection as an Adjuvant to Pain and Lymphedema Management in Terminal Cancer: Two Case Reports  [PDF]
Clark K. Choi, David I. Rosenblum
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.25054
Abstract: We are reporting two patients presented with intractable cancer pain that was treated with a novel application of an ultrasound-guided peripheral nerve block using corticosteroid. This technique offered relief to both patients whom otherwise their cancer pain was difficult to manage. The first patient developed lymphedema to the right axilla from metastatic squamous cell carcinoma. After multiple injections were deposited around the brachial plexus, lymphedema on the right axilla decreased slightly in size; however, range of motion improved post-procedure prior to his discharge one week later. In the second patient with left inguinal lymphadenopathy from metastatic left ureteral transitional cell carcinoma, there was a dramatic reduction in lymphedema in the left groin and leg as well as a considerable decrease in pain score during a two week follow-up after the peri-neural and peri-lymphatic femoral block. A 75% improvement in patient satisfaction was reported in the office visit’s questionnaire form. Corticosteroids can be used as an adjuvant to peripheral nerve block to decrease the pain secondary to lymphedema caused by the inflammatory response from metastatic cancer. This application can provide an alternative way to manage severe cancer-related pain caused by lymphedema in both upper and lower limbs.

The Past, Present, and Future of Public Health Surveillance
Bernard C. K. Choi
Scientifica , 2012, DOI: 10.6064/2012/875253
Abstract: This paper provides a review of the past, present, and future of public health surveillance—the ongoing systematic collection, analysis, interpretation, and dissemination of health data for the planning, implementation, and evaluation of public health action. Public health surveillance dates back to the first recorded epidemic in 3180 B.C. in Egypt. Hippocrates (460 B.C.–370 B.C.) coined the terms endemic and epidemic, John Graunt (1620–1674) introduced systematic data analysis, Samuel Pepys (1633–1703) started epidemic field investigation, William Farr (1807–1883) founded the modern concept of surveillance, John Snow (1813–1858) linked data to intervention, and Alexander Langmuir (1910–1993) gave the first comprehensive definition of surveillance. Current theories, principles, and practice of public health surveillance are summarized. A number of surveillance dichotomies, such as epidemiologic surveillance versus public health surveillance, are described. Some future scenarios are presented, while current activities that can affect the future are summarized: exploring new frontiers; enhancing computer technology; improving epidemic investigations; improving data collection, analysis, dissemination, and use; building on lessons from the past; building capacity; enhancing global surveillance. It is concluded that learning from the past, reflecting on the present, and planning for the future can further enhance public health surveillance. 1. Introduction The term “surveillance”, derived from the French roots, sur (over) and veiller (to watch) [1], is defined in the dictionary as the “close and continuous observation of one or more persons for the purpose of direction, supervision, or control” [2]. For the purpose of this paper, the following definition is used, “Public health surveillance is the ongoing systematic collection, analysis, interpretation and dissemination of health data for the planning, implementation and evaluation of public health action” (see Section 2.3 below). Public health surveillance is considered to be an essential public health function [3, 4]. A public health system is said to have five essential functions: population health assessment, health surveillance, health promotion, disease and injury prevention, and health protection [5]. Public health surveillance is considered the best weapon to avert epidemics [6]. The objective of this paper is to provide a review of the past, present, and future of public health surveillance. The section on the past includes an account of major epidemics in human history, the historical milestones
Atom optical elements for Bose condensates
S. Choi,K. Burnett
Physics , 1997, DOI: 10.1103/PhysRevA.56.3825
Abstract: A simple model for atom optical elements for Bose condensate of trapped, dilute alkali atomns is proposed and numerical simulations are presented to illustrate its characteristics. We demonstrate ways of focusing and splitting the condensate by modifying experimentally adjustable parameters. We show that there are at least two ways of implementing atom optical elements: one may modulate the interatomic scattering length in space, or alternatively, use a sinusoidal, externally applied potential.
Quantum non-demolition measurements using Bose-Einstein condensates
S. Choi,K. Burnett
Physics , 2001, DOI: 10.1088/0953-4075/35/1/107
Abstract: We study possible scenarios for quantum non-demolition measurements using Bose-Einstein condensates. We show that the interactions between condensate atoms makes it possible to measure the atom number with minimal back action on the system. This is an example of atomic nonlinear optics that has significant implications in the quantum state preparation of the Bose condensates.
Observation of the eta_c(2S) in exclusive B-->K KsK-pi+ decays
S. -K. Choi
Statistics , 2002, DOI: 10.1103/PhysRevLett.89.102001
Abstract: We report the observation of a narrow peak in the KsK-pi+ invariant mass distribution in a sample of exclusive B-->K KsK-pi+ decays collected with the Belle detector at the KEKB asymmetric energy e+e- collider. The measured mass of the peak is M=3654+-6(stat)+-8(syst) MeV/c^2 and we place a 90% confidence level upper limit on the width of Gamma<55 MeV/c^2. The properties agree with heavy-quark potential model expectations for the eta_c(2S), the n=2 singlet S charmonium state.
Relations between Lauricella's triple hypergeometric function $F_A^{(3)}(x,\,y,\,z)$ and Exton's function $X_{8}$
Junesang Choi and Arjun K. Rathie
Advances in Difference Equations , 2013, DOI: 10.1186/1687-1847-2013-34
Abstract: Very recently Choi et al. derived some interesting relations between Lauricella's triple hypergeometric function $F_A^{(3)}(x,\,y,\,z)$ and the Srivastava function $F^{(3)}[x,\,y,\,z]$ by simply splitting Lauricella's triple hypergeometric function $F_A^{(3)}(x,\,y,\,z)$ into eight parts. Here, in this paper, we aim at establishing eleven new and interesting transformations between Lauricella's triple hypergeometric function $F_A^{(3)}(x,\,y,\,z)$ and Exton's function $X_{8}$ in the form of a single result. Our results presented here are derived with the help of two general summation formulae for the terminating ${}_2F_1(2)$ series which were very recently obtained by Kim et al. and also include the relationship between $F_A^{(3)}(x,\,y,\,z)$ and $X_{8}$ due to Exton.

Combined Spinal-Epidural Analgesia for Laboring Parturient with Arnold-Chiari Type I Malformation: A Case Report and a Review of the Literature

Abstract: Anesthetic management of laboring parturients with Arnold-Chiari type I malformation poses a difficult challenge for the anesthesiologist. The increase in intracranial pressure during uterine contractions, coughing, valsalva maneuvers, and expulsion of the fetus can be detrimental to the mother during the process of labor and delivery. No concrete evidence has implicated high cerebral spinal fluid pressure on maternal and fetal complications. The literature on the use of neuraxial techniques for managing parturients with Arnold-Chiari is extremely scarce. While most anesthesiologists advocate epidural analgesia for management of labor pain and spinal anesthesia for cesarean section, we are the first to report the use of combined spinal-epidural analgesia for managing labor pain in a pregnant woman with Arnold-Chiari type I malformation. Also, we have reviewed the literature and presented information from case reports and case series to support the safe usage of neuraxial techniques in these patients. 1. Introduction Arnold-Chiari type I malformation (ACM-I) is a congenital neurological anomaly associated with prolapse of the cerebellar tonsils into the magnum foramen [1, 2]. Approximately 30% to 50% of the ACM-I patients have associated syringomyelia. Incidence of ACM-I ranges between 0.56% and 0.77% on magnetic resonance imaging (MRI) studies, of which 15% to 30% are asymptomatic. This abnormality is mostly predisposed to women, with a female-to-male ratio of 3?:?1. Symptoms including headaches, neck and shoulder pain, paresthesia, loss of pain and temperature sensation in the upper extremities, and unsteady gait are the usual manifestations seen during early adolescence into adulthood. Severity of the symptoms ranges from mild when tonsillar herniation is larger than 5?mm to severe if it is more than 12?mm on the sagittal MRI view [3]. A combined spinal-epidural (CSE) technique was used to provide labor analgesia for our parturient with ACM-I. We also conducted a literature search for our case presentation using a public accessible medical database MEDLINE. Individual key words were entered into the query: “Arnold-Chiari,” “vaginal delivery,” “pregnancy,” “combined spinal-epidural analgesia,” “epidural analgesia,” “spinal analgesia,” “cesarean section,” “perioperative outcomes,” and their combinations. Only articles in English language were selected. The database search yielded limited number of articles, mainly case reports and case series (Table 1).
