1/46. Early autonomic dysreflexia.INTRODUCTION: During the stage of spinal shock the conventional view is that autonomic activity is abolished. Here, evidence is presented that autonomic activity is still present. patients: Four patients with acute cord transactions are presented: one new case and three from the literature. DEFINITIONS: The definitions of spinal shock and autonomic dysreflexia are given. methods: All four cases showed acute autonomic dysreflexia between 7 and 31 days after acute cord transection at a stage when the tendon reflexes were abolished. RESULTS: Two cases showed a severe rise in blood pressure; the two earlier cases, before blood pressure was routinely recorded, profuse sweating. In two cases autonomic dysreflexia was obtained when the bladder was overdistended with 1000 ml and 1600 ml. In the other two cases it occurred in response to traumatic catheterisation. This was found when supramaximal stimuli were applied. It has not been recorded routinely as, with modern management, the bladder does not get overdistended or traumatised. DISCUSSION: Other evidence, the blood pressure, and urethral tone is presented to show that sympathetic reflex activity of the cord is not abolished during spinal shock. CLINICAL SIGNIFICANCE: The clinical importance of this is that autonomic dysreflexia can be seen at an early stage and it should be considered in the differential diagnosis of a sick patient immediately after spinal injury.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/46. Sigmoid colon rupture secondary to Crede's method in a patient with spinal cord injury.Crede's method is a manual suprapubic pressure exerted with a clenched fist or fingers, used to initiate micturition, in patients with spinal cord injury (SCI) who have neurovesical dysfunction. It is usually a benign maneuver unassociated with any major complications. This paper will illustrate a case report involving a sigmoid colon rupture secondary to Crede's method in a patient with SCI. Various techniques of Crede's method are briefly described. It is recommended that patients with quadriplegia avoid forceful use of Crede's method, as it may cause contusion of the abdominal wall and injuries to internal viscera, possibly leading to colonic rupture. It is believed that this is the first reported case of such an unusual complication of Crede's method in patients with SCI.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
3/46. Xanthogranulomatous funiculitis and epididymo-orchitis in a tetraplegic patient.STUDY DESIGN: A case report of xanthogranulomatous funiculitis and epididymo-orchitis. Xanthogranulomatous inflammation is an uncommon, non-neoplastic process characterised by destruction of tissue, which is replaced by a striking cellular infiltrate of lipid-laden macrophages. CASE REPORT: A 21-year male sustained complete tetraplegia at C-6 level, after a fall in 1998. The neuropathic bladder was managed with an indwelling urethral catheter. He had many unsuccessful trials of micturition. Sixteen months after the cervical injury, he noticed swelling of the left side of the scrotum following removal of a blocked catheter. He was prescribed antibacterial therapy. Four weeks later, physical examination revealed a hard and irregular swelling encompassing the testis, epididymis and spermatic cord. The clinical diagnosis was epididymo-orchitis progressing to pyocele. Through a scrotal incision, the swollen testis, epididymis and diseased segment of the spermatic cord were removed en masse. Histopathology showed extensive areas of necrosis, with xanthogranulomatous inflammation in the spermatic cord and to a lesser extent in the testis/epididymis. CONCLUSION: Repeated episodes of high-pressure urinary reflux along the vas deferens during dyssynergic voiding, and subsequent interstitial extravasation of urine together with chronic, low-grade, suppurative infection possibly led to development of xanthogranulomatous inflammation in the testis and the epididymis. Since tissue destruction is a feature of xanthogranulomatous inflammation, the definite and curative treatment is either complete (or, where applicable, partial) excision of the affected organ in most of the cases.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
4/46. Occlusion of left common iliac vein by a distended urinary bladder in a male with paraplegia due to spinal cord injury.STUDY DESIGN: A report of a male subject who sustained paraplegia at T-5 level due to spinal cord injury (SCI) 18 years ago, and in whom, occlusion of the left common iliac vein by a distended bladder was detected during a routine follow-up. OBJECTIVES: To illustrate a rare complication of chronic distension of the urinary bladder viz occlusion of the left common iliac vein, which persisted even after providing adequate bladder drainage by intermittent catheterisation. SETTING: Regional spinal injuries Centre, Southport, UK. methods: As part of a routine follow-up, we performed intravenous urography by injecting 50 ml of Ultravist 300 in a vein over the dorsum of the left foot. Opacification of collateral veins in the pelvis was seen in the 5- and 10-min films, which suggested iliac venous occlusion. In order to confirm the diagnosis, contrast was injected intravenously in the left foot and venography was performed. RESULTS: Venography revealed a distended left common iliac vein with contrast flowing into the right internal iliac vein through collateral veins in the pelvis; the right common iliac vein and inferior vena cava were patent. Duplex Doppler sonography showed compression of left common iliac vein by the posterior wall of a distended bladder with absence of blood flow through the compressed segment. Computerised tomography (CT) confirmed the diagnosis of extrinsic compression of the left common iliac vein against the promontory of sacrum by a distended bladder. CT excluded other causes for iliac vein occlusion. CONCLUSION: In a male subject with SCI, chronic bladder distension produced occlusion of the left common iliac vein. health professionals caring for individuals with SCI should be aware that long-standing bladder distension could cause pressure effects upon adjacent structures in the pelvis.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
5/46. herpes zoster induced neuropathic bladder--a case report.herpes zoster infection involving the sacral dermatomes has been associated with bladder dysfunction and, although rarely, with acute urinary retention. Less than 150 cases have been reported in the literature. After reviewing our institute's chart records covering a period of time dating from 1991 to 2001, we found that three of our patients had developed acute urinary retention following herpes zoster skin lesions of the S2-4 dermatomes. Herein we report our findings. These three patients had previously been found to have normal voiding status. However, at the time of complaint urodynamic studies revealed detrusor areflexia or detrusor hyporeflexia with decreased sensation of bladder filling. After micturation recovery, repeat urodynamic studies revealed detrusor pressure and bladder sensation recovery. After one to six weeks of treatment, all three patients could void spontaneously without catheterization. We found that, when treated with antiviral medication, supportive analgesics, and temporary urinary drainage, which included urethral catheterization and suprapubic cystostomy, acute urinary retention associated with herpes zoster has a generally favorable prognosis. In other words, we found that in spite of its rarity, herpes zoster induced neuropathic bladder dysfunction is reversible when treated appropriately.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
6/46. Two cases of unusual urethral complications after resection of sacrococcygeal teratoma.This report describes 2 rare complications of a sacrococcygeal teratoma leading to urethral obstruction in 1 case and midurethral necrosis in the other. The anomalies appear to be based on pressure necrosis of the urethra by mechanical compression between the symphysis pubis and the teratoma.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
7/46. autonomic dysreflexia manifested by severe hypertension.BACKGROUND: autonomic dysreflexia (AD) is a sudden and exaggerated autonomic response to stimuli in patients with spinal cord injuries or dysfunction above the splanchnic sympathetic outflow (T5-T6). hypertension is a relatively common manifestation of AD. CASE REPORT: We describe a case of a young man with T4-T6 spinal cord tumor who developed severe hypertension before any other clinical feature of AD, leading to a subsequent clinical evaluation and the correct diagnosis. Treatment with labetalol was only partially successful in controlling the elevated blood pressure. hypertension resolved immediately after bladder decompression. CONCLUSIONS: AD manifested by severe hypertension is uncommon. Bladder decompression appears to be safe and effective for management of hypertension in patients with AD.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
8/46. Ambulatory blood pressure monitoring in persons with chronic spinal cord injury.BACKGROUND: hypertension alone or in the presence of autonomic dysreflexia (AD) may be underdiagnosed and consequently mismanaged in people with chronic spinal cord injury (SCI). blood pressure (BP) derangements caused by AD are characterized by labile BP, in addition to episodic hypertension. Consequently, random BP readings often prove insufficient, which makes traditional outpatient evaluation and management suboptimal. Because elevated BP is common to essential hypertension (EH) and AD, distinction between the 2 entities proves challenging. The distinction is imperative because the treatments differ. Conventional BP monitoring in the office may miss labile BP patterns and episodic BP elevations. Ambulatory BP monitoring (ABPM) is used in the general population to improve the diagnosis and management of hypertension. ABPM provides the average BP level, circadian rhythm, and short-term BP variability. There is a paucity of ABPM studies in persons with SCI. OBJECTIVE: To explore the role of ABPM in individuals with SCI. methods: This study is a case description and detailed analysis of the use of ambulatory blood pressure monitoring (ABPM) in 3 persons with chronic SCI. RESULTS: Three cases were identified in which the diagnosis of autonomic dysreflexia, exaggerated blood pressure variability and disruption of circadian blood pressure pattern was delayed using conventional blood pressure evaluation. ABPM aided in diagnosis by providing the average blood pressure level, circadian rhythm and short-term BP variability. CONCLUSION: Because conventional office BP monitoring may miss labile BP patterns and episodic BP elevations, it is limited in the SCI population. ABPM may improve the outpatient management of blood pressure abnormalities in individuals with chronic SCI by clarifying mechanisms and patterns of BP in this patient population.- - - - - - - - - - ranking = 3.6666666666667keywords = pressure (Clic here for more details about this article) |
9/46. Extravasation of the contrast media during voiding cystourethrography in a long-term spinal cord injury patient.OBJECTIVE: To present complications and pitfalls in voiding cystourethrography (VCUG) and introduce a guideline for performing VCUG in a long-term spinal cord injury (SCI) patient with neurogenic bladder dysfunction (NBD) and contracted bladder. STUDY DESIGN: A case report. SETTING: Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, thailand. METHOD: We describe a chronic C(5) tetraplegic man with NBD and contracted bladder, who developed autonomic dysreflexia (AD), gross hematuria and extravasation of contrast median during VCUG. RESULT: A foley catheter was retained after VCUG. AD was resolved and urine cleared after a week of continuous bladder irrigation. CONCLUSION: VCUG should be performed with caution in a long-term SCI patient with NBD and contracted bladder. Forceful pushing of the contrast media by the hand-injection method caused abrupt distention of the contracted bladder, damaged bladder mucosa and aggrevated AD. We suggest a guideline as follows: report bladder capacity and AD, if present, in an X-ray requisition form; use the gravity-drip method, stop the drip and drain the contrast media if a sudden headache and rising of blood pressure (BP) develop; observe urine colour, and report if bleeding or AD occurs.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
10/46. Management of the uninhibited bladder by selective sacral neurectomy.The authors report the treatment of incontinence due to uninhibited bladder contractions by selective sacral neurectomy in nine patients, four without evidence of neurological disease. A detailed and objective analysis of bladder and urethral function, together with quantitation of clinical features, was made before and after operation. Seven patients were either cured or greatly improved. The overall increase in bladder capacity and reduction of uninhibited activity were statistically significant. The resting urethral sphincter pressure was unchanged, but the contractility of the voluntary external sphincter was slightly impaired. Criteria for such neurectomies are discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = pressure (Clic here for more details about this article) |
