Urological symptomatology in patients with reflex sympathetic dystrophy

PURPOSE: We determined the effect of reflex sympathetic dystrophy on lower urinary tract function. MATERIALS AND METHODS: A total of 20 consecutive patients (16 women and 4 men) with neurologically verified reflex sympathetic dystrophy was referred for voiding symptoms, including urgency, frequency, incontinence and urinary retention. No patient had had voiding symptoms before the initial trauma that induced reflex sympathetic dystrophy. Evaluation included medical history, physical examination, video urodynamic testing and cystoscopy. RESULTS: Mean patient age was 43.4 +/- 10.2 years (range 28 to 58) and mean duration of urological symptoms was 4.9 +/- 3.6 years (range 1 to 14). Urodynamic study demonstrated a mean cystometric bladder capacity of 417 +/- 182 ml. (range 120 to 700). The urodynamic diagnoses included detrusor hyperreflexia in 8 patients, detrusor areflexia in 8, sensory urgency in 3 and detrusor hyperreflexia with detrusor-external sphincter dyssynergia in 1. In 4 women genuine stress urinary incontinence was also documented urodynamically. CONCLUSIONS: Reflex sympathetic dystrophy may have a profound effect on detrusor and sphincter function.     

Segmental reflex sympathetic dystrophy: clinical and scintigraphic criteria

Clinical and scintigraphic criteria are proposed for the diagnosis of segmental reflex sympathetic dystrophy. Eight patients met previously described clinical criteria for reflex sympathetic dystrophy with involvement limited to only a portion of the hand. The delayed phase of the three-phase radionuclide bone scan was found to be highly sensitive (100%) for this small group of patients. Consecutive bone scans (n = 127) performed during a 6-month period for a variety of upper extremity problems were reviewed, and a segmentally diffuse pattern of tracer uptake was found to be highly specific (98%) for segmental reflex sympathetic dystrophy. Recognition and documentation of a more localized form of reflex sympathetic dystrophy will allow earlier recognition and treatment, which is an important factor in a successful outcome for managing pain dysfunction disorders.     

Balloon atrial septostomy under two-dimensional echocardiographic control: a new outlook

The comorbidity of eating disorders and reflex sympathetic dystrophy syndrome in the same patients raises the possibility of a common pathway for both conditions. Reflex sympathetic dystrophy syndrome may be manifesting itself in those individuals who have sympathetic overdrive. Microtrauma, often induced by compulsive exercise, and depression may be contributory factors. It is recommended that: patients with eating disorders who develop pain in an extremity should be investigated for possible reflex sympathetic dystrophy syndrome; patients with reflex sympathetic dystrophy syndrome should be discouraged from dieting, and eating disorders should be suspected if they begin to lose weight or are already malnourished.     

Dorsal sympathectomy and management of thoracic outlet syndrome with VATS

Dorsal sympathectomy and the management of the thoracic outlet syndrome have been considerably improved with the use of video assistance because it affords both magnification and an improved light system. Two techniques of video assistance were employed in the group of patients described here. One involved the sympathectomy done through three ports using standard video-assisted thoracic surgical methods. The second technique involved a transaxillary incision with removal of the first rib using video-assistance magnification and light, operating either directly or secondarily while visualizing the image on the television set. (The vast majority of cases have been performed using this latter technique.) Major indications for performing dorsal sympathectomy include (1) hyperhidrosis, (2) Raynaud's phenomenon, (3) Raynaud's disease, (4) causalgia, (5) reflex sympathetic dystrophy, and (6) vascular insufficiency of the upper extremity. Except for hyperhidrosis, all of the other indications require the usual diagnostic techniques, including cervical sympathetic blockade to assess whether the symptoms are relieved by temporary blockade of the sympathetic ganglia. In 326 patients, sympathectomy, performed either alone or in conjunction with first-rib removal for relief of the thoracic outlet syndrome, has been successful. In only 6 patients has sympathetic activity recurred in less than 6 months. Initially all of them were treated conservatively. Three of the 6 required a repeat sympathectomy. Postsympathectomy neuralgia occurred in only 2 of more than 326 patients. Both cases were managed successfully in a conservative fashion. Among the patients in whom a Horner's syndrome was not deliberately induced, the syndrome developed in 2. In both, the syndrome resolved spontaneously within several months.     

Algodystrophy (reflex sympathetic dystrophy syndrome) and causalgia: novel concepts regarding the nosology, pathophysiology, and pathogenesis of complex regional pain syndromes. Is the sympathetic hyperactivity hypothesis wrong?

Concepts regarding the nosology, pathophysiology and pathogenesis of reflex sympathetic dystrophy syndrome are currently in a state of flux. Causalgia and reflex sympathetic dystrophy syndrome are now generally felt to be on the same continuum and as a result interest for defining criteria for the latter condition has waned. The pathogenic role of adrenergic sympathetic activity has been so successfully challenged that the last international consensus conference judged inappropriate any reference to the sympathetic system in the terms used to designate these conditions, thus confirming the position long defended by most French authors. The vasomotor abnormalities may be due to antidromic release of neuromediators by the endings of polymodal C fibers. These fibers do not belong to the sympathetic system but often travel with sympathetic nerves, a characteristic that may explain the efficacy of sympathetic nerve blocks, although other possibilities exist including a placebo effect. Also, efferent sympathetic fibers may undergo activation by nonadrenergic mediators. The mechanisms capable of initiating and perseverating activation of polymodal C afferents are being actively investigated and have been found to exhibit similarities with the mechanisms underlying peripheral and central sensitization of pain-producing afferents. Growth factors, such as nerve growth factor, may play an important role in causalgia. In "reflex sympathetic dystrophy syndrome", microcirculatory stasis may contribute to the initiation or perpetuatation of the disorders. Further work on the nerve supply to the venular network and on the venoarterial reflex is needed.     

The reflex sympathetic dystrophy syndrome in patients who have had a spinal cord injury

Patients suffering from a spinal cord injury often present with a pain syndrome. Although the reflex sympathetic syndrome is a common diagnosis in some forms of neurological disease such as patients with a stroke, it is less frequent in those with a spinal lesion. The authors report eight patients with reflex sympathetic dystrophy who had a spinal cord injury. The diagnosis and treatment are discussed along with a review of literature.     

Calcitonin treatment in reflex sympathetic dystrophy: a preliminary study

Reflex sympathetic dystrophy is one of the important complications effecting the rehabilitation programmes of hemiplegic patients in a negative manner by causing pain and function loss. In this study, the aim was to investigate the effects of salmon calcitonin treatment in reflex sympathetic dystrophy that develops in hemiplegia. Forty-one patients with hemiplegia resulting from cerebrovascular events and stage 1-2 reflex sympathetic dystrophy were included in the study. Salmon calcitonin, 1 x 100 IU/day intramuscularly for 4 weeks, was administered to 25 of these patients (calcitonin group) to the other 16 patients physiological saline, 1 ml/day intramuscularly for 4 weeks, was administered (control group). At the end of the fourth week of treatment the pain score of the calcitonin group was significantly lower than that of the control group. Shoulder abduction and external rotation, wrist flexion and metacarpophalangeal extension of the calcitonin group were found to be significantly better than those of the control group. In the calcitonin group the significant decrease in pain and tenderness resulted in improvement of range of motion and motor functions.     

Secondary breast cancer in patients presenting with osteosarcoma: possible involvement of germline p53 mutations

Second malignancies following treatment for osteosarcoma are unusual. Breast cancer occurring in patients with osteosarcoma has been reported following therapeutic chest irradiation. We now report three cases of breast cancer occurring in young women who were successfully treated for osteosarcoma. These women had not received therapeutic chest irradiation and in two of the three women there was no family history of breast cancer. Peripheral blood was available for study from one case. Of import, this case demonstrated a germline mutation in exon 7 of the tumor suppressor gene, p53. The mutation was detected by constant denaturing gradient gel electrophoresis and confirmed by DNA sequencing. In this particular patient, inactivation of the p53 gene may be involved in the development of both the first and second malignancy.     

Occurrence and etiology of tooth caries in wearers of fixed dentures during the war]

This retrospective study was undertaken to determine the usefulness of intravenous regional anesthetic (IVRA) blocks containing ketorolac and lidocaine in the management of sympathetically-mediated pain, and to determine what factors, if any, predicted success with this technique. Sixty-one patients with reflex sympathetic dystrophy presenting to a university-affiliated teaching hospital's pain management center were evaluated. Patients underwent one or more treatments with IVRA blocks containing ketorolac and lidocaine. The duration of pain, site of extremity affected, pain symptomatology, duration of relief from the first IVRA block, absence of pain following a series of IVRA blocks and side-effects from the IVRA blocks were determined. Of the 61 patients, 16 had complete response (26 percent), 26 had a partial response (43 percent) and 19 had no response (31 percent) to the ketorolac-containing IVRA. The only symptom which predicted a failure with this therapy was allodynia. No patient had serious side effects from the IVRA block; dizziness following tourniquet release occurred in 41 percent (n = 25) of the patients. IVRA block containing ketorolac is a useful and minimally invasive technique for the management of patients with reflex sympathetic dystrophy.     

Reflex sympathetic dystrophy: result of autonomic denervation?

1. To investigate the nature of sympathetic dysfunction in the pathogenesis of reflex sympathetic dystrophy, the microcirculatory vasoconstrictive responses to dependency were investigated in the skin of the hand of 76 reflex sympathetic dystrophy patients with unilateral disease by means of laser Doppler flowmetry (in perfusion units) and capillary microscopy. The patients were divided into three stages according to their perception of skin temperature (stage I in the case of a stationary warmth sensation, stage II in the case of an intermittent warmth and cold sensation, and stage III in the case of a stationary cold sensation). The vasoconstrictive responses were induced by lowering of the affected hand. 2. As compared to controls, the mainly sympathetically mediated vasoconstrictive response at thermoregulatory level of the skin microcirculation, as measured by laser Doppler flowmetry, was attenuated at stage I (1.82 versus 1.41, P < 0.05), stage II (1.82 versus 1.09, P < 0.0001) and stage III (1.82 versus 1.14, P < 0.01), suggesting the involvement of sympathetic denervation at all stages of the reflex sympathetic dystrophy syndrome. This sympathetic denervation may also account for the observed increase in thermoregulatory skin blood flow at stage I as compared to controls (152 versus 81, P < 0.01). 3. Since sympathetic denervation has been reported to cause increased sensitivity of vascular structures to catecholamines, the decrease in thermoregulatory skin blood flow at stages II (54 versus 81, P < 0.05) and III (31 versus 81, P < 0.05), both as compared to controls, may result from hypersensitivity to catecholamines of skin microvessels. 4. The sympathetically independent vasoconstrictive response at the nutritive level of skin microcirculation, as measured by capillary microscopy, was impaired only at stage III as compared to controls (1.04 versus 2.06, P < 0.05). This divergence in microvascular reactivity upon dependency of the nutritive and thermoregulatory subsystems also supports the hypothesis of sympathetic dysfunction.(ABSTRACT TRUNCATED AT 250 WORDS)     

Unusual endocrine presentations of nasopharyngeal carcinoma

BACKGROUND: Nasopharyngeal carcinoma is endemic in Southern China and the majority of patients present with local symptoms due to the tumor. METHODS: This report describes two unusual cases of occult nasopharyngeal carcinoma in which the patients initially presented with endocrine manifestations. RESULTS: The first patient presented with Cushing's syndrome secondary to ectopic adrenocorticotropic hormone (ACTH) production. Nasolaryngoscopy showed a growth in the left nasal fossa and biopsy revealed a poorly differentiated nasopharyngeal carcinoma that exhibited positive immunostaining for ACTH. The second patient presented with a 10-month history of bone pain over both lower limbs. She was normocalcemic but her serum alkaline phosphatase was markedly elevated. A bone biopsy showed both osteoclastic and osteoblastic activity with widespread fibrosis suggestive of Paget's disease. Three months later, she developed third cranial nerve palsy. Computed tomography investigation revealed a soft tissue mass filling the sphenoid and ethmoid sinuses. Biopsy showed a poorly differentiated nasopharyngeal carcinoma. The bone biopsy was reviewed and immunohistochemistry demonstrated the presence of cells positive for the epithelial marker AE1/3 within the fibrous stroma. Radio-labeled in situ hybridization showed that Epstein-Barr virus early RNA was present in these tumor cells and the bone lesions were in fact metastases. CONCLUSIONS: Nasopharyngeal carcinoma can present with rather atypical symptoms that may lead to a delay in diagnosis. Therefore, in high risk populations, it is important to consider nasopharyngeal carcinoma as a possible primary tumor in patients with occult carcinomas.     

Significance of nondiagnostic fine-needle aspiration of the thyroid

BACKGROUND: Fine-needle aspiration biopsy (FNAB) has been shown to be rapid and cost effective in the evaluation of thyroid nodules. The significance of nondiagnostic (unsatisfactory) FNAB is uncertain, however. METHODS: We reviewed 345 consecutive thyroid FNABs and identified 59 patients with initially unsatisfactory specimens. These patients had follow-up to determine whether their thyroid nodules proved to be malignant. RESULTS: Three patients (5.1%) were found to have organ-confined papillary carcinoma of the thyroid, the largest tumor mass measuring 1.2 cm. Six patients (10.2%) had benign adenomas. CONCLUSIONS: In most cases of initially nondiagnostic FNAB of a thyroid nodule, neoplasia is not found subsequently. A minority of cases may still harbor malignancy. None of our patients in whom repeated FNA was either nondiagnostic or suggestive of benign disease were ultimately found to have a malignancy.     

Occult cancer in patients with venous thromboembolism: which patients, which cancers

We have previously demonstrated that patients with idiopathic venous thromboembolism (VTE) have a higher frequency of underlying cancer. Now we present a retrospective analysis of our 5-year experience with a series of 674 consecutive otherwise healthy patients, and a more restricted battery of diagnostic tests. Occult cancer was found in 15 patients during admission. The diagnostic tools which led to suspect occult cancer were: abdominal CT-scan (4 patients); high carcinoembryonic levels (2 patients); and high prostate-specific antigen levels (9 patients). Eight further patients were diagnosed of cancer after discharge. Cancer was more commonly found in patients with idiopathic VTE: 13/105 patients (12%) versus 10/569 patients (2%); p <0.01; O.R.: 7.9 (95% CI: 3.14-20.09). During the same period of time we diagnosed VTE in 147 patients with previously known cancer. When overall considered, VTE was the first sign of malignancy in most patients with prostatic and pancreatic carcinoma. On the contrary, most patients with breast, lung, uterine and brain cancers developed VTE as a terminal event of the disease. At variance with VTE patients and previously known cancer, most patients with occult malignancy were at an early stage. Further studies are needed to confirm whether patients with idiopathic VTE could benefit from screening for occult cancer. Meanwhile, our findings may serve as guidelines for physicians in this field.     

Biopsy-negative malignant esophageal stricture: diagnosis by endoscopic ultrasound

Endoscopic ultrasound (EUS) of the esophagus has been used primarily in staging biopsy-proven cancers. Its use as a primary diagnostic modality for esophageal malignancy has not been previously described. We report our recent experience in four patients with dysphagia and endoscopic biopsies negative for malignancy, including one patient with clinical and manometric features suggestive of achalasia. In all cases, EUS revealed a large infiltrating tumor invading through the esophageal wall into the surrounding tissues, and in one case into the aorta. Computed tomography suggested the possibility of a tumor in only one of the cases. Two patients underwent esophagectomy and were found to have adenocarcinoma. Two patients underwent repeat biopsy with alternative aggressive biopsy techniques and were found to have squamous cell carcinoma. We conclude that EUS is useful in the diagnosis of esophageal cancer and should be performed in selected patients with esophageal strictures whose biopsies are negative for malignancy; i.e., those with suspicious endoscopic or radiographic appearance, atypical presentation (e.g., profound weight loss, short duration of symptoms, or advanced age), and failure to respond to treatment.     

Lipopolysaccharide induces sickness behaviour in rats by a vagal mediated mechanism

A 52-year-old man was hospitalized for a right adrenal tumor which had been incidentally found by abdominal CT scan for examination of colon cancer. Laboratory and endocrine findings were within the normal limits except for increased urinary concentrations of noradrenaline and dopamine. Adrenal angiography revealed that the feeding artery of the tumor was the inferior suprarenal artery. Adrenal venous blood sampling studies detected no abnormalities in the concentrations of catecholamine, cortisol or aldosterone. Right adrenalectomy was performed and the tumor was histologically diagnosed as ganglioneuroma. Ganglioneuroma is a benign tumor originating from the sympathetic nerve ganglion. The adrenal origin of the tumor is relatively rare and 60 cases of adrenal ganglioneuroma including our case have been reported in Japan.     

Significance of the BTA test in bladder cancer: a multicenter trial. BTA Study Group Japan

Complex regional pain syndrome (CRPS) is a progressive, chronic illness that is enigmatic because the mechanisms for its pathogenesis have yet to be determined. Syndromes synonymous with CRPS are reflex sympathetic dystrophy, reflex neurovascular dystrophy, causalgia, algoneurodystrophy, sympathetically maintained pain, clenched fist syndrome, and Sudek's syndrome. The diagnosis of CRPS is categorized into three stages: acute, dystrophic, and atrophic. CRPS is most often precipitated by peripheral trauma (crushing injuries, lacerations, fractures, sprains, burns, or surgery) to soft tissue or nerve complexes. The pathogenesis for CRPS has been speculated as being either a disease process of the peripheral nerves, a disease process of peripheral soft tissue, or a disease process of the spinal cord. Patients suffering from CRPS may be limited in their ability to function in a self-directed, independent fashion. A longitudinal study of CRPS on 1,348 patients revealed that 96% of the study subjects still suffer some pain and disability regardless of the duration of the disease or course of treatment. Although the primary etiology for CRPS is not clearly understood, key progress has been made in terms of establishing a psychological as well as therapeutic treatment plan once the diagnosis has been made.     

Severe self-healing nail dystrophy in a patient on peritoneal dialysis

The unusual case of a patient on peritoneal dialysis who progressively developed onychodystrophy of the hands 2 months after Acinetobacter peritonitis had been reported. The nail disease consisted of acute pseudoclubbing, elkonyxis, severe Beau's lines and onychomadesis and showed spontaneous recovery within 4 months. Although reminiscent of severe Beau's lines and reflex sympathetic dystrophy, this observation shows a peculiar nail disorder of unknown cause.     

Subcutaneous morphine infusion by syringe driver for terminally ill patients

We describe a 16-year-old boy with reflex sympathetic dystrophy after a fracture of the right hand. He had inflammation of the proximal nail folds and arrested nail growth of digits 3, 4 and 5 on the right hand. After 2 months lymphatic drainage treatment, the changes of the nails had disappeared.     

Reflex sympathetic dystrophy syndrome secondary to organophosphate intoxication induced neuropathy

Reflex sympathetic dystrophy or Sudeck's atrophy is a syndrome that can usually be followed by a traumatic insult. This disorder is accompanied by signs and symptoms of vasomotor instability, trophic skin changes, and rapid development of bony demineralization. This report presents a case with reflex sympathetic dystrophy syndrome secondary to organophosphate intoxication induced neuropathy. The patient was threated with calcitonin well.
