Drug and alcohol use in orthopedic trauma patients: a prospective study

Six groups of 16 rats each were fed a standard diet for 8 weeks. Aluminium (Al) complexed with organic anions (citrate, lactate, malate, or tartrate) was added to the diet of four of the groups and aluminium hydroxide to the diet of one group (control 'Al +'). Aluminium concentrations in the diets were 1500-2000 mg/kg. The sixth group (control 'Al -') served as control. Plasma, bone (femur), kidneys, cerebral cortex and cerebellum levels of aluminium were determined at 4 and 8 weeks. All the complexing agents increased tissue accumulations, compared with values in the two control groups, especially citrate in bone and kidneys and lactate in cerebral cortex. There were no significant differences (P < 0.05) in aluminium levels in the tissues considered between the 'Al +' and 'Al -' control groups. Our results show the ability of dietary organic acids to increase aluminium absorption and tissue accumulation and indicate that concurrent intake of aluminium and dietary organic acids is not appropriate.     

Immediate orthopedic surgery in multiple trauma

The increase in mortality and morbidity from multiple trauma due to road accidents, industrial trauma and combat injuries obligates treatment based on emergency systems and trauma centers. Follow-up of the frequency of different types of injury calls attention to increasing involvement of the orthopedic surgeon in primary treatment. This situation calls for appropriate deployment of immediate surgical treatment which will rapidly enable mobility. We present several methods for immediate orthopedic treatment of multiple-trauma patients.     

Occipital nerve neuralgia as postoperative complication. Views on etiology and treatment

INTRODUCTION: Meta-iodobenzylguanidine (MIBG) in its 131I-labeled form is clinically used as a tumor-targeted radiopharmaceutical in the diagnosis and treatment of adrenergic tumors. This well established drug may have additional clinical applications as a radiosensitizer or hyperthermic agent, ie., MIBG reportedly inhibits mitochondrial respiration in vitro. The mechanism for MIBG inhibition of cellular oxygen consumption is uncertain. Moreover, MIBG reportedly stimulates glycolysis both in vitro and in vivo. Our studies show the effect of MIBG on 9L glioma oxygen consumption and redox status with tumors cells in vitro and in vivo. MATERIALS AND METHODS: The effects on electron transfer were determined by following oxygen consumption with a Clark oxygen electrode. Fluorescence measurements were used to determine effects of MIBG on intracellular electron acceptors, NADPH and flavoproteins, in vitro and in vivo. 31P-NMR was used to determine alterations in tumor cell pH in vivo. RESULTS: Our results show the inhibition of oxygen utilization with MIBG for cell suspensions in vitro. The same results were demonstrated for tumor cell suspensions rapidly isolated from tumors grown in rats. Moreover, NAD(P)H and flavoprotein (Fp) fluorescence changes were observed to rapidly occur following MIBG addition in vitro. Changes in intracellular pH measured with 31P-NMR, in vivo, precede the changes in fluorescence of NAD(P)H and Fp obtained with frozen sections of tumor. CONCLUSIONS: We conclude that 31P-NMR measurements and fluorescence changes, following MIBG injection, can be used as criterion for selecting the proper time to treat tumors with ionizing radiation or hyperthermia.     

Mild brain trauma in sports. Diagnosis and treatment guidelines

OBJECTIVES: To investigate whether infectious events around birth and during early infancy are likely to be of relevance in MS pathogenesis. SUBJECTS AND METHODS: Data are available from two regions in The Netherlands: Groningen (n=320) and Rotterdam (n=226). Simultaneous clustering in birth date and birth location of MS cases is tested by the methods of Mantel, Knox and Jacquez. RESULTS: No evidence was found for a space-time interaction between place and time of birth. CONCLUSION: Perinatal infectious events are unlikely to be a major factor in determining MS susceptibility.     

The treatment of suppurative pyelonephritis

From 1986 in the urological clinic of the Dagestan Medical Academy 82 patients received surgical treatment for purulent pyelonephritis caused by urinary occlusion. Nephrostoma or pyelostoma were applied in most of the patients. In the postoperative period the patients were given antiinflammatory and infusion therapy. Recently, 40 patients were exposed to adjuvant laser treatment. The comparison of the treatment results demonstrated better outcomes in patients exposed to laser radiation. Normalization of renal function, T- and B-immunity in them was faster.     

Surgical treatment of suppurative mastitis

Due to the improvement of chemotherapy some changes in the last 10 years took place concerning the indications of active surgical interventions. Special aspects of tuberculosis of the spine and joints are emphasized.     

Thrombosis in trauma and orthopedic surgery. Prevention, diagnosis, therapy

The connection between drugs and violence has been well documented. Understanding the intricacies of this connection is essential to finding effective interventions. Much has been written about the psychosocial causes of these problems, but there have been few studies exploring the biophysiological interface between drug effects, violent behavior and brain metabolism. Over the past eight years, The Amen Clinic has been extensively involved in the clinical use of brain SPECT imaging to evaluate complicated neuropsychiatric problems, especially related to the issues of both violence and substance abuse. From this work several clinical patterns, as well as brain SPECT imaging patterns, have been recognized that may help further our understanding of these problems. In this article, following a brief review of the literature on drugs, violence and the brain, five clinical examples are explored; the authors show how these support the clinical utility of incorporating SPECT imaging into psychiatric assessment of drug abuse and violence. Finally, a model is proposed to help explain the complex interaction between the brain, violence and drug abuse.     

Vaginal pressure trauma: a complication of jet-skis

Vaginal trauma was caused by a jet-ski fall. The lesion occurred due to hyperpressure of the upper half of the vagina. A protocol for diagnosis and treatment are proposed with emphasis on laparoscopy which is not always used.     

Parapharyngeal emphysema--an unusual complication of temporal bone trauma

Medical cure of fungal prosthetic valve endocarditis (PVE) is rarely reported. We describe a patient with C. tropicalis PVE in whom surgery was believed to be contraindicated. A huge tricuspid valvular vegetation was identified by two-dimensional transthoracic echocardiography. After a total of 2 g of amphotericin B, she continued with fluconazole daily with a follow-up of fifteen months. Our patient represents the first case of long term survival of C. tropicalis PVE successfully managed without surgery.     

Severe head injury combined with orthopedic and vascular trauma of the limbs

From 1982 to 1992, 2766 brain injury patients were admitted to the University Hospital San Cecilio of Granada, Spain. In 873 cases head injury was concomitant with other injuries but the association of severe head injury and combined orthopedic and vascular trauma of the limbs was observed only in 23 cases (incidence 2%). Thirteen patients were scheduled for revascularization, and of these secondary amputation was mandatory in two cases to keep rising intracranial pressure under control. Except for epidural hematomas which constitute an absolute neurosurgical emergency, combined orthopedic and vascular trauma of the limbs can be treated before head injury. However, we prefer to work with two operating teams simultaneously. Physical examination and judicious arteriography provide means for prompt diagnosis and treatment of the injured limb. The compartment syndrome should be anticipated and fasciotomy should be used routinely. Vascular repairs normally using reverse autogenous vein are the first priority, but we must always bear in mind the deleterious effects of the revascularization syndrome which expose the brain to a second aggression, and amputation, when necessary, should be undertaken to reduce mortality.     

Diagnosis and management of laryngeal trauma in sports

The management of sports-related laryngeal trauma presents a diagnostic and therapeutic challenge. The application of basic treatment principles such as airway monitoring, thorough physical examination, and fiberoptic laryngeal examination will direct the management. Further radiologic examination or surgical intervention may be required to adequately assess and manage the injury. We review the diagnosis, treatment, and management in a case of laryngeal fracture that occurred during a National Hockey League game.     

The role of childhood sexual trauma in the etiology of borderline personality disorder: Considerations for diagnosis and treatment.

Highlights recent research findings that demonstrate a connection between severity and type of sexual abuse and presentation of borderline-like symptoms. Similarities are drawn between the type of symptoms that make up a posttraumatic stress disorder (PTSD) diagnosis, and those that compose borderline personality disorder (BPD). Neither the PTSD nor BPD diagnoses are completely adequate to address the conditions of psychiatric patients with sexual abuse histories. In PTSD, characterological dysfunction in response to severe abuse experiences is not represented in the diagnosis, while BPD attributes symptoms solely to characterological dysfunction without recognizing their adaptive nature in the face of childhood trauma. A more accurate and less stigmatizing diagnostic category for survivors of sexual abuse has a significant role in expanding the possibilities for successful treatment of these patients.

Prevention and treatment of renal insufficiency in patients with severe cranio-cerebral trauma

In 147 patients with severe craniocerebral injuries the functional state of the kidneys was examined. The incidence and peculiarities of renal function disorders were studied in such patients. A table is presented for the assessment of the degree of renal function disorders by the values of glomerular filtration and the level of nitrous products in blood. On the basis of the author's personal experience measures of prevention and treatment of renal failure in such cases are described.     

Use of flumazenil in the diagnosis and treatment of patients with coma of unknown etiology

OBJECTIVES: To evaluate the use of single-dose flumazenil in the diagnosis of coma of unknown etiology, and of continuous flumazenil infusion in the treatment of benzodiazepine-induced coma. DESIGN: Prospective study. SETTING: Emergency room and general medicine ward of a teaching hospital. PATIENTS: A total of 42 comatose adults in whom metabolic, neurologic, or traumatic causes of coma were excluded. INTERVENTIONS: a) Intravenous bolus injections of 0.25 mg flumazenil were given at 1-min intervals, either until improvement by two coma grades or a total dose of 2.0 mg was reached. b) Loading doses as in (a) followed by a maintenance infusion administered as long as indicated by repeated coma grade evaluation. MEASUREMENTS AND MAIN RESULTS: a) Of 34 patients, 28 received only the flumazenil loading dose responded promptly. Twenty-one of 25 available urine samples of the responding patients contained only benzodiazepine metabolites. Four urine samples contained benzodiazepines in combination with other drugs. Six patients did not respond to the flumazenil loading dose. The urine of three patients contained a combination of benzodiazepines and another coma-exerting drug; the remaining three were negative. A total of 24 patients, who initially responded to flumazenil loading, deteriorated to their previous coma state and were admitted to the general medical ward. Six (25%) patients developed complications related to hospitalization and their bedridden state. b) Eight other patients, who deteriorated after an initial loading dose, received a second iv bolus of flumazenil, followed by maintenance infusions over 5 to 24 hrs. Their hospital course was uneventful. CONCLUSIONS: These findings indicate that flumazenil is safe and effective in the diagnosis of benzodiazepine-induced coma. Furthermore, the use of continuous flumazenil maintenance infusion is of considerable therapeutic value in patients who exhibit deterioration after initial response to the single loading dose.     

Diagnosis and management of blunt abdominal trauma

The records of 437 patients with blunt abdominal trauma admitted to Charity Hospital, New Orleans, from 1967-1973 have been reviewed and computer-analyzed. There was an 80% increase in the incidence of blunt abdominal trauma when compared with the preceding 15-year experience. Forty-three per cent of all the patients presented with no specific complaint or sign of injury. Blunt abdominal injury was usually diagnosed preoperatively using conventional methods including history, physical examination, and routine laboratory tests and x-rays. Abdominal paracentesis via a Potter needle had an 86% accuracy. The incidence and management of specific organ injuries with associated morbidity and mortality have been discussed. Mortality and morbidity continue to be significant in blunt abdominal trauma. Isolated abdominal injuries rarely (5%) resulted in death, even though abdominal injuries accounted for 41% of all deaths. Associated injuries, especially head injury, greatly increased the risk. The insidious nature of blunt abdominal injury is borne out by the fact that more than one-third of the "asymptomatic" patients had an abdominal organ injured. A high index of suspicion and an adequate observation period therefore are mandatory for proper care of patients subjected to blunt trauma.
