From hysterical psychosis to Reactive Dissociative Psychosis

In this paper Reactive Dissociative Psychosis (RDP) is seen as a post-traumatic stress response and as a subcategory of Brief Reactive Psychosis (BRP). A review of the literature and the evolution of RDP from Hysteria and Hysterical Psychosis are given. Issue is taken with defining the duration of BRP as Brief. The authors argue that long-standing psychotic symptoms may be traumatically induced. The dissociative aspects of RDP as its key feature and the concomitant implications for accurate diagnosis are proposed. The usefulness of applying hypnosis in RDP treatment is summarized in a case study from Janet and detailed in a case from the authors' practice.This article was accepted for publication under the Editorship of Charles Charles R.

Total parenteral nutrition during acute pancreatitis: Clinical experience with 156 Patients

Over a 3-year period, 156 of 815 patients admitted to a single institution with acute pancreatitis received total parenteral nutrition (TPN) for 2,572 patient days. Seventy had simple acute pancreatitis (group I) and 86 (group II) developed local complex disease (pseudocyst, abscess, or necrotic gland). In groups I and II, respectively, days without oral intake (NPO) were 13.6±1.5 (SEM) and 24.0±2.1 (p<0.005), hospital days were 19.8±1.7 and 35.8±3.2 (p<0.005), and duration of TPN was 10.9 ±1.0 and 21.0±2.3 days (p<0.005). Thirty-three patients in group I and 53 in group II required exogenous insulin. Alteration of standard formulas was necessary in 87 patients, but cessation of therapy was necessary in only one instance. Twenty catheters were removed for suspected sepsis with only 3 confirmed cases. Fat-based formulas were well tolerated in 15% of patients. During TPN, body weight rose from 95.0±2.4% to 97.4±4.3% of ideal in group I and remained at 90.5±1.8% in group II. Albumin rose from 3.36±0.10 to 3.50±0.08 g/dl in group I and from 3.01±0.07 to 3.35±0.07 g/dl in group II. The entire cohort differed from 10 randomly chosen patients who did not receive TPN in terms of days NPO (2.8±0.3) and hospital days (5.5±0.6). Variables associated with prolongation of hospital stay and time NPO were number of prognostic criteria, local complex disease, and underlying chronic pancreatitis only in select groups. We conclude that during acute pancreatitis, TPN can be administered safely but with careful monitoring and we recommend early aggressive therapy in the subgroups noted above and when underlying malnutrition exists. In the borderline patient, TPN may be administered by peripheral vein until the severity of disease is manifest.

Resumen En el curso de un período de 3 años, 156 de 815 pacientes hospitalizados en una sola institución por pancreatitis aguda recibieron nutrición parenteral total (NPT) durante 2,572 paciente-días. Setenta presentaban pancreatitis aguda simple (grupo I) y 86 (grupo II) desarrollaron enfermedad local complicada (pseudoquiste, absceso, o necrosis de la glándula). Las siguientes fueron las características de los grupos I y II, respectivamente: días sin ingesta oral (NPO) 13.6±1.5 (SEM) y 24.0±2.1 (p<0.005), días de hospitalización: 19.8±1.7 y 35.8±3.2 (p<0.005), y duración de la NPT: 10.9±1.0 y 21.0 ±2.3 días (p<0.005). Trienta y tres pacientes en el grupo I y 53 en el grupo II requirieron insulina exógena. Se requirió alterar la fórmula estándar en 87 pacientes, pero sólo fue necesario cesar la terapia en un caso. Veinte catéteres fueron retirados por sospecha de sepsis, pero sólo en 3 se confirmó. Las fórmulas a base de grasa fueron bien toleradas en 15% de los pacientes. En el curso de la NPT el peso corporal ascendió de 95.0±2.4% a 97.4±4.3% del peso ideal en el grupo I y se mantuvo a un 90.5±1.8% en el grupo II. La albúmina ascendió de 3.36±0.10 a 3.50±0.8 g/dl en el grupo I y de 3.01±0.07 a 3.35±0.07 g/dl en el grupo II. Toda la cohorte se diferenció de un grupo de 10 pacientes escogidos al azar que no recibieron NPT en términos del número de días NPO (2.8±0.3) y de días de hospitalización (5.5±0.6). Las variables que aparecieron asociadas con prolongación de la hospitalización y el tiempo NPO fueron el número de criterios de pronóstico, la enfermedad complicada, y la presencia de pancreatitis crónica subyacente sólo en grupos seleccionados. Nuestra conclusión es que en el curso de la pancreatitis aguda, la NPT puede ser administrada con seguridad pero bajo monitoría cuidadosa, y recomendamos terapia agresiva precoz en los subgrupos anotados anteriormente y cuando exista mal nutrición concomitante. En el paciente limitrofe se puede administrar la NPT por vía periférica hasta cuando la gravedad de la enfermedad se haga manifiesta.

Résumé Pendant une période de 3 ans, 156 des 815 patients admis pour pancréatite aiguë ont reçu une alimentation parentérale totale (APT), soit en tout 2,572 jours patient. Soixante dix patients (groupe I) avaient une pancréatite simple et 86 (groupe II) avaient aussi une maladie locale complexe (pseudokyste, abcès ou nécrose du pancréas). La durée du jeûne était respectivement de 13.6±1.5 (ET) et de 24.0±2.1 (p<0.005), la durée moyenne de séjour était respectivement de 19.8±1.7 et de 35.8 ±3.2 (p<0.005) alors que la durée d'APT était respectivement de 10.9±1.0 et de 21.0±2.3 jours (p<0.005). Trente-trois patients dans le groupe I et 53 dans le groupe II avaient besoin d'insuline exogène. Un changement dans la formule standard a été nécessaire chez 87 patients mais l'APT n'a du être arrêté complètement que chez un patient seul. Vingt cathéters ont été enlevés avec suspicion de sepsis, confirmée cependant dans 3 cas seulement. Les compositions à base de lipides ont été bien tolérées chez 15% des patients. Pendant l'APT, le poids du corps s'est élevé de 95.0±2.4% à 97.4±4.3% du poids idéal chez les patients du groupe I et est resté à 90.5±1.8% chez ceux du groupe II. L'albumine s'est élevée de 3.36±0.10 à 3.50 ±0.08 g/dl dans le groupe I et de 3.01±0.07 à 3.35±0.07 g/dl dans le groupe II. La durée du jeûne (2.8±0.3) et la durée moyenne de séjour (5.5±0.6) de l'ensemble des patients différaient de ces mêmes données chez 10 autres patients choisis au hasard. Les facteurs associés avec un séjour hospitalier prolongé et sans alimentation orale étaient le nombre de critères pronostiques, l'existence de complications locales, et de pancréatite chronique sous-jacente chez certains patients. Nous concluons que pendant la pancréatite aiguë, l'APT peut être administrée sans danger sous contrôle permanent et nous conseillons un traitement agressif et précoce dans le sous groupe mentionné plus haut ou quand existe un état de nutrition déficient. Chez le patient limite, on peut se contenter d'APT par une veine périphérique tant que des signes de gravité ne se manifestent pas.

Use of a pulse oximeter for determination of systolic blood pressure in a helicopter air ambulance

INTRODUCTION: Traditional methods of determining blood pressure may be unreliable (auscultation or palpation) or unavailable (direct arterial cannulation) in the air medical environment. The authors investigated the combination of a pulse oximeter with a standard sphygmomanometer (blood pressure) cuff as an alternative method. METHOD: The pulse oximeter is applied to a finger on the same upper extremity on which a standard blood pressure cuff had been applied. A baseline blood pressure was obtained by palpation or an automated blood pressure device. One minute later, the systolic blood pressure (SBP) was determined by inflating the blood pressure cuff until the pulsatile display on the pulse oximeter was obliterated. This was taken as the systolic blood pressure. RESULTS: Complete data were obtained on 116 patients, with 223 data pairs. The SBP as obtained by the baseline method was strongly correlated with the SBP obtained by the pulse oximeter display obliteration method (r = 0.90, p < 0.001). CONCLUSION: The obliteration of the wave form display on a pulse oximeter is an accurate, convenient, inexpensive and readily available alternative method of determining SBP.     

Educational and geographic career pathways of rural vs. urban hospital administrators

Information on academic and geographic career patterns was obtained through a survey of 93 urban and rural hospital administrators in the State of Washington in 1990 (90 percent response rate). A greater proportion of urban than rural administrators had advanced degrees (93 versus 74 percent). While the most common career pathways were "always urban" (39 percent) and "always rural" (20 percent), there was little support for the presumption that hospital administrators use rural positions as stepping stones into urban careers.     

The percentage of articles which were accepted or rejected for publication in the Dutch Journal of Medicine in 1997

OBJECTIVE: To determine the acceptance and rejection percentages of articles submitted to the editors of the Nederlands Tijdschrift voor Geneeskunde (NTvG) in 1997. DESIGN: Retrospective. METHOD: The data on all articles reviewed by the editors of the NTvG in 1997 were extracted from the registration system in April 1998. These included the outcome of the review process (rejection or acceptance for publication or no definite decision yet), the article category (e.g., original article, review article), and whether the article had been solicited by the editors or was a spontaneous submission. RESULTS: In 1997, 845 articles were received. Of these 28% (240) were rejected and 59% (497) were accepted for publication. On 13% (108) no decision had been made (in April 1998). Of the articles decided upon 36% were rejected (extrapolated). 705/845 (83%) articles were unsolicited: of these 33% (235) were rejected and 54% (382) accepted; on 13% (88) the decision was pending. The solicited articles numbered 140 (17%); of these 4% (5) were rejected and 82% (115) were accepted; on 14% (20) no decision had been made yet. CONCLUSION: The rejection of articles submitted to NTvG in 1997 was 36% (in 1990 38%). Solicited articles were rejected less frequently than unsolicited ones. The yearly number of articles submitted and the rejection percentage have not changed drastically during the last eight years.     

Physical examination--the significance of Homan's sign]

Homans's sign is often used in the diagnosis of deep venous thrombosis of the leg. A positive Homans's sign (calf pain at dorsiflexion of the foot) is thought to be associated with the presence of thrombosis. However, Homans's sign has a very poor predictive value for the presence or absence of deep vein thrombosis, like any other symptom or clinical sign of this disease.     

Uniform safety of beating heart surgery using the octopus tissue stabilization system

BACKGROUND AND PURPOSE: Minimally invasive coronary artery bypass grafting (CABG) has been facilitated by the introduction of the Octopus Tissue Stabilization system (OTS). OTS improves exposure immobilizing the heart with minimal hemodynamic effects allowing multivessels off cardiopulmonary bypass (CPB) CABG. The purpose of this study was to compare the utilization and clinical outcome of the OTS in three geographically distinct centers. METHODS: 239 patients who underwent OTS-CABG at Allegheny University Hospital/Medical College of Pennsylvania, Harrisburg Hospital, and Park Nicollet Clinic/HealthSystem Minnesota were reviewed. Age, acuity of patients, and number and type of vessels bypassed were recorded. Complications, mortality, length of hospital stay, incidence of conversion to CPB and blood transfusions, and operating room costs were compared to risk matched control patients who underwent CPB CABG during the same period. RESULTS: Results were similar in all three centers. The average age was 62.3 years. Emergent operation was necessary in 7%-10% of patients, the operations averaged 1.8 grafts/patient. Arteries bypassed were LAD, DIAG, OM, RCA, PDA, and RPLB. There were 96% of operations completed without CPB. Morbidity was low (12%). Atrial fibrillation and blood transfusion rate were decreased. Mortality was 0 compared with a predicted mortality of 1.6%. Hospital length of stay was shorter and operating room costs were 61% lower. CONCLUSIONS: OTS provides predictable reproducible immobilization allowing the performance of single and multiple off-pump CABG to almost all coronary branches with minimal morbidity and decreased costs in a variety of patients. Similar findings from three different centers suggests that these results are easily reproducible.     

Breast Biopsies with ABBI(R): Experience with 183 Attempted Biopsies

When first introduced, the advanced breast biopsy instrumentation (ABBI^®) system seemed to have many advantages as a diagnostic procedure. Problems have arisen, however, both in terms of patient unsuitability and mechanical failure. In addition, there has been uncertainty as to whether the complete lesion removal it afforded could be considered definitive treatment in malignant cases. Incision margins were looked at to investigate that possibility. Of the 183 patients we saw in our first year of experience with ABBI, 48 (26%) were rejected for being poor candidates for it. In the remaining 132 biopsies there were 31 (23%) technical difficulties. All told, 14 malignancies were discovered, all of which appeared to have pathology-free incision margins radiologically. However, 13 of these 14 (93%) proved on pathologic examination to have residual malignancy. ▪
