Acute onset of halos and glare: Bilateral corneal epithelial edema with cystic eruptions—atypical presentation of amiodarone keratopathy

Background Amiodarone (Cordarone™; Wyeth, Ayerst, New York) is a potassium channel blocking antiarrythmal medication indicated for recurrent ventricular fibrillation and recurrent hemodynamically unstable ventricular tachycardia. Chemically, it is classified as an iodinated benzofuran derivate antiarrythmal drug not chemically related to any other available antiarrhythmic drug. Documented side effects of amiodarone include neurologic, gastrointestinal, dermatologic, cardiovascular, and ophthalmic. The ophthalmic abnormalities include optic neuropathy, optic neuritis, papilledema, corneal deposits, photosensitivity, lens opacities, and macular degeneration. Corneal microdeposits are seen in virtually all patients who receive amiodarone for more than 6 months. Corneal microdeposits result secondary to the secretion of amiodarone by the lacrimal gland with accumulation on, and absorption by, the corneal epithelium. Approximately 10% of these patients become symptomatic with glare and halos; however, that alone is usually not enough to precipitate intervention. Case report A 69-year-old woman presented to our office with a 2-week history of halos and glare in both eyes (OU). Her ocular history was significant for occasional contact lens wear. Her systemic history was significant for atrial fibrillation, for which she was taking amiodarone daily for the last 6 years. Six weeks before the onset of her chief complaint, her daily amiodarone dosage was increased from 100 mg to 300 mg. Ophthalmic examination found decreased visual acuities OU, amiodarone keratopathy (subepithelial verticillata), and diffuse corneal epithelial edema with diffuse sodium fluorescein staining OU. The corneal compromise was treated in 2 ways: the source medication was discontinued, and the ocular signs were medicated with a prophylactic topical antibiotic along with supportive preparations (tears/lubricants) and monitored over 2 weeks until full elimination of the pathologic signs and their symptoms. Even after complete resolution of the acute keratitis, the infiltrative keratopathy persisted along with the initial complaints of halos and glare. The supportive treatments were maintained over the course of 2 months until full recovery. Conclusion By exclusion, it was determined that the subepithelial depositions and cystic formations were secondary to an acute amiodarone dosage increase by a new practitioner. Prompt communication resulted in the physician discontinuing that medicine.

The dead little girl

Despite our sensitivity to the suffering experienced by adult clients, victims of childhood sexual abuse, echoes of these events continue to reverberate throughout their lives. Rarely does a client afford us more than a glimpse into the agony caused by those traumatic experiences. This paper describes the treatment of a woman whose initial complaint centered on a lack of desire for sexual contact with her husband. As the case evolved, she began to recall childhood traumatic experiences that had remained long repressed. Her literary talent allowed a level of expression not often available in the therapy setting. Excerpts from her writings provide a unique dimension to this case description.

Analysis of 95 cases of squamous cell carcinoma of the external and middle ear

Objective To analyze the clinical characteristics, 5-year survival, and prognostic factors of squamous cell carcinoma (SCC) of the external and middle ear. Methods A multi institutional study. Ninety five cases of patients from 10 institutions were reviewed on their age and sex distribution, initial complaints, stages, tumor locations, treatments, and outcomes. Prognostic factors were discussed based on the Pittsburgh staging system. Results This disease seems to appear in the elderly with a peak age of 50–69 years. Males appear to be more predisposed than females with an odd ratio of 1.7. The initial complaints were not typical, while 12.6% of patients presented a history of recurrent otitis externa or chronic otitis media. Regional metastasis was recognized in 13.7% of patients, while no distant metastasis was confirmed. SCC located in the external ear could be detected in an earlier stage than that in the middle ear. The overall 5-year survival was 66.8% in total, and decreased significantly with stage. SCC in stages I and II was susceptible to each therapeutic strategy with a 5-year survival of 100%. Operation combined with radiotherapy and/or chemotherapy was the major treatment for stages III and IV SCC, while radiotherapy and chemotherapy were applied mainly for those who had been considered inappropriate for operation. The overall survival was 67.2% for stage III and 29.5% for stage IV, and operation with pathologically tumor free margin could improve the survival to 72.7% when combined with radio- and chemotherapy. Stage, completeness of operation with tumor free margin, recurrence, and metastasis have significant influence on survival. Conclusion Local infiltration seems to be the main behavior of SCC in the external and middle ear. Early diagnosis and treatment were important because SCC in the earlier stage is susceptible to be cured. For tumors of advanced stage, operation should be performed with pathologically tumor free margin, and operation combined with radiotherapy and chemotherapy could improve the survival. Tumor stage adds more influence on survival than its location. Recurrence and metastasis mainly occur in advanced stages and result in a poor survival.

Fatal outcome from extreme acute gastric dilation after an eating binge

A 22-year-old woman is presented with acute gastric dilation after an eating binge, who died of complications of acute reperfusion syndrome. A young patient was admitted in our clinic with critical condition without any significant previous medical history. Her initial complaints--diarrhea, vomiting and abdominal pain--began after an enormous food intake. There was no history of medications or toxic substances. Physical examination showed a normally-developed, well-nourished female in severe distress with an extremely distended abdomen. Femoral pulses were absent. The US and CT scan showed a dilated stomach, extended into the pelvis, dislocating the intestinal organs and compressed the aorta and mesenteric veins. Urgent laparotomy was performed. An enormously distended stomach was encountered without volvulus, obstruction or adhesions. About 11 liters of gastric content was removed gastrotomy and nasogastric tube. Following the gastric decompression, the mesenteric and femoral pulses reappeared. During the operation, the cardio-respiratory status was stabilized, but in the following 24 hours irreversible shock developed, possibly due to the reperfusion of the retroperitoneal organs and the lower extremities. In the postoperative period disseminated intravascular coagulopathy developed. In an uncontrollable state of diffuse bleeding, 36 hours post-operation, the patient died. In retrospective investigation, the family confessed that previous psychological treatments which aimed at her bulimic attacks. Acute gastric dilatation is very uncommon and is of various etiologies, two of these being anorexia nervosa and bulimia. Several cases documenting complications of gastric dilatation were published; however, such severe complications, involving gastric infarction and compression of the aorta with ischemic injury of the bowels and lower extremities, are rare.

Surgery for Gastrointestinal Endometriosis: Indications and Results

Background: Although gastrointestinal endometriosis is an uncommon and often unexpected finding, the best treatment requires removal of all endometriotic lesions.The purpose of our study was to report our experience with the diagnosis and treatment of bowel endometriosis. Material and Methods: From January 1997 to January 2004, 13 patients (mean 35.7y; range 21–55y) were operated for bowel endometriosis. We noted: age, history of endometriosis, previous pregnancies, preoperative investigations and symptoms, operative procedure and intraoperative findings. Follow-up varied between one month postoperative examination and seven years.Results: Presenting symptoms of the cases were: acute appendicitis (3), dysmenorrhoea (7), constipation (6), pelvic pain (2), rectal bleeding (3) and dyspareunia (2). Operative management was performed in accordance with the anatomical distribution. Seven patients had a history of previous operations and multifocal involvement was present in 61.5% of cases. At a median follow-up of 12.2 months, 83.3% had complete relief of their initial complaints, with only one reoperation needed. The pregnancy rate after surgery was 66.6%. Preoperative tests were: ultrasound for ovarian endometriomas, coloscopy, barium enema, vaginal palpation for detecting rectovaginal involvement, MRI and CT scan. These tests predicted the extension of endometriotic process correctly in 50% of the cases.Conclusions: Endometriosis of the sigmoid and rectum is rare but can give rise to severe gastrointestinal and pelvic symptoms. Preoperative investigations are not infallible in predicting the extent of the disease, sometimes placing the surgeon before a dilemma, because it involves mostly young women in the reproductive phase of life. The colorectal surgeon, therefore, should seek the advice of an experienced gynaecologist and vice versa. Removal of all endometriotic lesions is mandatory for obtaining an optimal relief of symptoms.

Creutzfeldt-Jakob’s disease: case report with emphasis on the electroencephalographic features

Creuzfeldt-Jakob’s Disease is a rare neurodegenerative disorder that is included among the transmissible spongiform encephalopathies. The clinical features are those of a rapid progressive dementia with mioclonic jerks, which progresses to death in less than one year. We report the case of a 79 years old woman, with initial complaints of vertigo, visual and gait compromise, with an initial brain MRI, EEG and CSF that had no specific features of CJD. After 12 days she was again admitted to the hospital with a worsening of her symptoms, along with global spasticity, inability to walk and a further deterioration of speech and swallowing. A new EEG disclosed periodic triphasic complexes, typical of the disease. CSF had a positive 14-3-3 protein. She later evolved with mioclonic jerks, coma, multiple infectious complications and, ultimately, death 45 days after her second admission. We focus on the role of the EEG as an adjuctive eletrophysiological tool for the presumptive in vivo diagnosis of the disease.

Diffuse granulomatous necrotizing scleritis

A 34-year-old man presented with anterior scleral thinning in the right eye (RE) and a painful nodular scleritis in the left eye (LE). Fundus examination showed a healed vasculitis and an inferior epiretinal neovascular membrane in the LE. Topical and systemic oral steroids and antiviral medication were prescribed. One year later, optic disc hyperaemia and swelling and macular oedema became apparent in the LE. Pulsed intravenous steroids were administered for 1 year, when a nasal septum perforation and vitreous haemorrhage in the LE were diagnosed. The eye was enucleated 3.5 years after the initial complaint. Necrotizing granulomatous tissue replacing the sclera and subconjunctival granulomatous tissue were observed. Six months later, oedema and neovascularization of the right optic disc were observed and cyclophosphamide was started, with regression of the clinical signs. No systemic abnormalities have so far become apparent. Posterior scleritis is most often observed in patients with no signs of associated systemic autoimmune disease. The diagnosis in this case is most probably one of Wegener's granulomatosis (WG). In WG, the diagnosis is based on necrotizing granulomas of the respiratory tract, generalized focal necrotizing vasculitis and focal necrotizing glomerulonephritis. Eye involvement with WG has been reported in up to 58% of cases. Evaluation of the scleritis patient should include a detailed medical history, chest X-rays, blood tests, autoantibody serology and analysis of urinary sediment. Cyclophosphamide is the treatment of choice for patients with ocular manifestations of WG, polyarteritis nodosa or rheumatoid arthritis, either alone or in combination with systemic steroids. Visual loss is expected in 85% of individuals with severe necrotizing posterior scleritis.

Numb cheek syndrome as the first manifestation of anti–Hu paraneoplastic neuronopathy

Sirs: Unilateral numb cheek syndrome (NCS) has rarely been described as the first manifestation of malignancy due to neoplastic involvement of the trigeminal nerve, more specifically the maxillary branch [1, 2]. NCS as the first symptom of subacute paraneoplastic sensory neuronopathy has, to the best of our knowledge, never been reported. We present this case because its rarity led to a diagnostic delay of several months. A 47-year-old man presented with a one month history of numbness in the left cheek, both inner and outer surfaces. The area of numbness corresponded with the mandibular division of the left trigeminal nerve (V3). His medical history was unremarkable. Neurological examination was normal including the left V3 area. As the main part of the cheek is innervated by the buccal nerve we considered that our patient had a mandibular sensory neuropathy probably due to compression or infiltration of the nerve by local malignancy, as seen in other types of trigeminal mononeuropathy [3]. Ancillary investigations including contrast enhanced brain MRI, thorax CT and extensive laboratory examinations of the blood and urine were normal. Cerebrospinal fluid (CSF) examination revealed mild lymphocytic pleocytosis, slightly elevated protein of 0.69 g/l (0.2–0.5) and no malignant cells or oligoclonal bands. Although intracranial malignancy could not be ruled out an expectant policy was chosen by the patient. Two months later he complained of slightly unsteady gait. A second MRI of the brain and skull base was normal. Another 4 months later he noticed numbness of his left hand and foot. Neurological examination showed only left sided facial hypalgesia. Nerve conduction studies were consistent with a non uniformly distributed, predominantly axonal, sensorimotor neuropathy, most pronounced in the left extremities. Repeated conventional CSF examination only showed an increased protein level of 0.86 g/l. Anti-Hu antibodies in CSF were detected with indirect immunofluorescence and Western blotting techniques. A second thorax CT and whole body PET-scan eventually showed a solitary lesion in the right hilus, which proved to be a metastasis of an anaplastic small cell carcinoma on histological examination. Although the primary tumour remained unrevealed, a paraneoplastic multifocal mainly sensory neuronopathy associated with presumed primary small cell lung carcinoma was diagnosed and combined chemotherapy started. Fifteen months after the initial complaint the primary tumour remained undetected and no metastases were found. The neuropathy progressed resulting in very severe sensorimotor neuropathy with asymmetric painful paresthesias, diffuse proprioceptive loss and weakness in all extremities. In patients with paraneoplastic anti-Hu associated neuropathy (AHN) involvement of the cranial nerves may be present but is very rarely the presenting symptom. AHN most commonly presents as a subacute sensory neuropathy, less frequently as a sensorimotor neuropathy [5, 6]. These neurological symptoms typically antedate the diagnosis of cancer and most commonly involve the extremities [4–7]. In 306 patients with malignancy and associated anti-Hu antibodies, 50 % of the patients had a sensory neuropathy [4–6]. Three of them had trigeminal nerve involvement, but in no one was cheek numbness described as the only presenting symptom. As initially no primary tumour was found, we did not consider AHN as a potential cause of the unilateral cheek numbness in our patient. The final diagnosis was reached because of the extension of the sensory symptoms and eventually the evidence of an asymmetric sensorimotor neuropathy. The diagnostic delay between the NCS and final diagnosis was 6 months, which lies within the range of reported diagnostic delays in AHN patients [4–7]. As early treatment of the underlying malignancy is the mainstay of treatment, we report this patient in order to add NCS to the list of presenting symptoms of AHN.

Endometrial Carcinoma Metastasis to the Distal Phalanx of the Hallux: A Case Report

Endometrial carcinoma is the most common invasive cancer of the female genital tract and accounts for 7% of all invasive cancer in women. Bony metastasis is uncommon with endometrial carcinoma and distal metastasis is very rare. The purpose of this paper is to present a case of an 86 year-old female with endometrial carcinoma metastasis to the distal phalanx of the hallux. The patient had a known history of endometrial carcinoma with metastases (FIGO IIIC), and had been diagnosed with pulmonary and bony metastases 2 months prior to presentation. Her initial foot complaint was of a painful, infected ingrown toenail. The infection continued to progress following avulsion of the nail, and the patient was then diagnosed with osteomyelitis. Given her past history, the possibility of metastasis to the hallux was also considered. A hallux amputation was performed, and the pathology report revealed the diagnosis of endometrial carcinoma metastasis to the distal phalanx of the hallux. While the amputation site healed uneventfully, the patient refused further treatment measures for her carcinoma and eventually succumbed to the disease.

Hair loss: is there a relationship with hair care practices in Nigeria?

BACKGROUND Hair loss occurs in all ethnic populations, but the etiology varies considerably from group to group. In black women, many forms of alopecia are associated with hair care practices. However, the causes of alopecias in African women have not been extensively investigated. OBJECTIVE This descriptive, cross-sectional, hospital-based study was undertaken to document common complaints on initial presentation for hair loss, hair care practices and patterns of hair loss, and to determine if there is a relationship between hair loss and hair care practices. METHODS A total of 39 female patients seen over a 12 month period were enrolled in the study. Demographic information recorded included age, sex, marital status and occupation. Information regarding medical history included initial presenting complaints, duration of hair loss, site of hair loss, whether there was skin or systemic involvement, hair care practices and the duration of these practices. Examination of the scalp, a hair-pull test, documentation of the pattern of hair loss, relevant laboratory tests and biopsies were carried out. RESULTS All 39 patients were adults. Major complaints at initial presentation, apart from hair loss, included itchy scalp in 17 patients (43.6%), painful scalp in 11 patients (28.2%), hair breakage in seven patients (17.9%) and flaking scalp in four patients (10.3%). All the women relaxed their hair at some point in time. Chemical relaxants were consistently used by 22 patients (53.7%), eight patients (20.5%) alternated these with plaits/braids, and nine patients (23.1%) wore extensions. The use of local concoctions in hair care management was reported by three patients (7.7%). Scarred alopecias were observed in 20 patients (51.3%), while 19 (48.7%) had non-scarred alopecias. Those who reported prolonged and frequent use of chemical relaxants [mean duration (+/- standard deviation) 23.2+/-9.3 years] exhibited scarred alopecia more commonly than those who did not often use chemical relaxants (P<0.001). The application of local concoctions or pomades was also a regular practice amongst females with scarred alopecias. CONCLUSIONS Itchiness, pain, ready hair breakage and flaking scalp were common complaints at initial presentation. A range of alopecias were documented, and it was also observed that duration of hair care practice and hair styling were relevant to hair loss, particularly for women with central centifugal cicatricial alopecias (CCCAs), which resulted in scarring.

Das Herz Handy®—ein neues telemedizinisches Servicekonzept für Herzpatienten

Telemedicine is a new milestone for the health care system in the care of patients with heart disease. New technologies and the possibilities of fast data transmission have enabled this step forward. The Cardiophone offers a new telemonitoring Service Concept, which is available 24 hours a day. The patient is by the aid of the Cardiophone connected with the Medical Service Center at just the press of a button, can record and transmit an ECG and can be localized by the incorporated GPS. We report about our experiences with 363 patients over 3 years. Out of 5064 patient contacts associated with 7561 calls, 559 emergency contacts occurred. From the initial main complaints, working diagnoses were established. The final confirmed diagnoses were arrhythmias (27.8%), coronary heart disease (25.9%), psychovegetative syndrome (12.7%), backbone pain (6.2%), gastrointestinal syndrome (3.6%), others (1.8%), and exclusion diagnosis (19.9%). Ten myocardial infarctions were diagnosed, of whom 3 were confirmed; the other 7 were treated as stabile angina pectoris. Overall 823 ECG were transmitted, in average 1.6 ECGs per emergency contact. In 131 ECGs changes of the ST-segment or T-wave could be documented; 26 patients showed a pacemaker ECG. Atrial and ventricular arrhythmias as well as conduction disturbances were seen. The majority of emergency contacts (n=477, 85.3%) were successfully managed by the Service Center. In 38 emergency contacts (6.8%) admission to hospital was recommended; in 4 cases (0.7%) an ambulance was activated via the local dispatcher by the Service Center and in 29 cases (5.2%) the emergency ambulance.

Catastrophic Presentation of Infant Botulism May Obscure or Delay Diagnosis

Three infants with infant botulism are presented to illustrate how atypical, early, and severe features may obscure or delay diagnosis. Two boys aged 6 weeks and 20 days, respectively, presented with rapid deterioration after brief periods of poor feeding, one with an apparent life-threatening event at home and the other with a full cardiopulmonary arrest. Initial abnormal laboratory findings of coagulopathy suggested sepsis in the first infant. In the second infant, severe acidosis and hypoglycemia suggested an underlying metabolic disorder. A third infant, aged 1 month, was hospitalized originally with an admitting diagnosis of "pharyngitis" resulting from his inability to take adequate feedings. He received intravenous fluids and antibiotics. One week later he suffered a respiratory arrest. Laboratory findings of severe hyponatremia and acidosis at the time of his arrest suggested a metabolic etiology. Even retrospectively, none of these infants had the typical initial complaint of constipation, and none were noted to have ptosis or facial weakness before catastrophic collapse. However, in each case, the parent had initially brought the child to the physician for "poor feeding" or "poor suck," which was not recognized by medical personnel as a result of bulbar weakness. Ultimately, all 3 infants were found to have infant botulism. All 3 had received antibiotics before catastrophic collapse, possibly contributing to the rapidity of the deterioration. Each recovered, although the delay in diagnosis made them ineligible for treatment with botulism immunoglobulin.

Hepatitis A Virus Infection Presenting With Seizures

Hepatitis A infection rarely causes extrahepatic manifestations. Here we present a 5-year-old patient with an initial complaint of nuchal rigidity and convulsions during the course of hepatitis A infection. Because hepatitis A virus RNA was demonstrated in the cerebrospinal fluid, it was thought that convulsions might be related to this viral infection.

Risk factors and early signs of Alzheimer's disease in a family study sample

Several predictors of Alzheimer's disease (AD) have been identified. However, the relevance and independent contribution of risk factors and of possible early signs such as mild cognitive impairment and subjective memory impairment on the development of AD has not been investigated prospectively in a cohort of non-demented elderly including first-degree relatives of AD subjects. The development of AD was investigated in 757 non-demented elderly. Initial diagnoses were made from personal interviews. Information on 633 subjects after 4.7 +/- 1.2 years (mean +/- SD) was obtained either from personal or family history interviews. Using forward logistic regression analysis, predictors were identified by comparing their presence in 38 subjects who developed AD and 577 subjects who remained non-demented. The most important predictors of later Alzheimer's disease were increased age (Odds ratio OR = 1.086/additional year, p < 0.001), initial subjective memory complaints (OR = 2.68, p = 0.019), initial mild cognitive impairment (OR = 2.51, p = 0.032) and female gender (OR = 2.84, p = 0.069). Exploratory analysis revealed that previous depression after the age of 60 years (OR = 2.37, p = 0.033) and the presence of the apolipoprotein E4 allele (OR = 2.49, p = 0.043) individually predicted new AD during follow-up. A positive family history of AD (i. e. being a first degree relative of a subject suffering from AD) did not significantly influence the development of AD (p > 0.2). Increased age, the presence of mild cognitive impairment, subjective memory impairment and gender are the most relevant independent predictors of later Alzheimer's disease that may be used in combination for clinical prediction of AD.

Expression of vascular endothelial growth factors and their receptors in human endometrium from women experiencing abnormal bleeding patterns after prolonged use of a levonorgestrel-releasing intrauterine system

Menstrual bleeding disturbances are a common initial complaint among users of the levonorgestrel-releasing intrauterine system (LNG-IUS). In this study, women who experienced bleeding disturbances recurring after a previous period of problem-free use and who therefore wanted removal of their LNG-IUD were investigated. Vascular endothelial growth factors (VEGFs) and their receptors are thought to be involved in normal endometrial angiogenesis. The aim of the study was to elucidate the possible association of these VEGF and receptors with bleeding disturbances among users of LNG-IUS. Endometrial biopsies were obtained from users of the LNG-IUS who complained of bleeding disturbances (n = 17) and from women without such problems (n = 14). The endometrial expression of these VEGFs and their receptors was analysed using immunohistochemistry. Endometrial endothelial cells from LNG-IUS users with menstrual bleeding disturbances exhibited significantly higher immunoreactivity for VEGFR-1 and VEGFR-3 than those from women without bleeding disturbances. Stromal cells showed significantly lower immunoreactivity for VEGF-A in samples from LNG-IUS users with bleeding disturbances than in those without. Changes in the expression of these angiogenic growth factors and their receptors in LNG-IUS-exposed endometrium might be involved in the formation of fragile and dysfunctional blood vessels that subsequently give rise to bleeding disturbances.

How accurate is the diagnosis of exercise induced asthma among Vancouver schoolchildren?

Background: Limited access to exercise testing facilities means that the diagnosis of exercise induced asthma (EIA) is mainly based on self-reported respiratory symptoms. This is open to error since the...

Interexaminer Reliability in Physical Examination of Pediatric Patients With Abdominal Pain

To test the interexaminer reliability of abdominal examinations performed by pediatric emergency medicine physicians and surgeons in an emergency department. A prospective cross-sectional study in which 3 different types of physicians (pediatric emergency department residents, pediatric emergency department attending physicians, and pediatric surgeons in training) independently examined a convenience sample of children (aged 3-19 years) with initial complaint of abdominal pain. The interexaminer reliability of 6 components of the abdominal examination (the presence or absence of abdominal distension, abdominal tenderness to percussion, abdominal tenderness to palpation, abdominal guarding, rebound tenderness, and bowel sounds) and the clinical diagnosis of peritonitis was tested. Sixty-eight patients were examined by pediatric emergency department residents and pediatric emergency department attending physicians. All 3 physician types examined 46 of these 68 patients. When comparing residents and attending physicians, the components of the abdominal examination showed less than moderate chance-adjusted agreement (kappa range, -0.04 to 0.38). When comparing attending physicians and surgeons, the presence of rebound tenderness showed moderate agreement (kappa = 0.54). The rest of the components demonstrated less than moderate chance-adjusted agreement (kappa range, -0.04 to 0.34). The components of the abdominal examination are poorly reliable between physician types. Only the "rebound tenderness" component of the abdominal examination shows moderate agreement between the pediatric emergency department attending physicians and the surgeon. No component of the abdominal examination appears to be consistently reliable. Interexaminer agreement must be considered when developing management strategies for acute abdomen. Interventions to improve reliability should be developed.

Is lumbar spondylosis a cause of urinary retention in elderly women?

Lumbar spondylosis (LS) is a common spinal degenerative disorder which causes various types of lower urinary tract dysfunction (LUTD). However, it is not certain whether LS may cause urinary retention in elderly women. In a period covering the past 3 years, we retrospectively reviewed: a) urodynamic case records of women with urinary retention (post-void residuals, PVR > 100 ml), b) the records of women with LUTD due to LS (cauda equina syndrome and spinal canal narrowing by MRI), and c) uro-neurological features of women who belonged to both a) and b). a) One-hundred women with a mean age of 58 years had urinary retention. The most common underlying disease was multiple system atrophy [19], followed by multiple sclerosis [13] and cervical/thoracic tumours [8]. LS was the fourth most common [5], with the highest age (71 years) of all diseases. b) Nineteen women with LUTD had LS (12, canal narrowing of 50-70%; 7 > 70 %), with a mean PVR volume of 60 ml. A fourth [5] of them had urinary retention, with severe spinal canal narrowing (all 5 > 70%). c) Thus, 5 women belonged to both a) and b). In 4 of these women, LUTD followed or occurred together with typical cauda equina syndrome symptoms such as sciatica and saddle anesthesia. However, one elderly woman presented with painless urinary retention, and absent ankle reflexes were the sole neurological abnormality. The urodynamic abnormalities underlying urinary retention included an underactive detrusor in all 5, bladder sensory impairment in 3, an unrelaxing sphincter in 2, a low compliance detrusor in one, neurogenic sphincter motor unit potentials in 2 of 4 studied, and cholinergic supersensitivity of the detrusor in one of 3 studied. Surgical decompression ameliorated urinary retention in 1 of 2 women who had surgery. In our series, only 5 percent of the women with urinary retention had LS, but LS poses a potential risk for retention, particularly in elderly women with severe spinal canal narrowing. Preganglionic somato-autonomic dysfunctions underlie this condition. It may appear as the sole initial complaint in cases in which no other obvious neurological abnormalities are found.

Change in Differential Diagnosis and Patient Management With the Use of Portable Ultrasound in a Remote Setting

Physicians practicing in remote areas are typically limited in their choice of diagnostic tools. The goal of this study was to determine whether the use of a portable ultrasound (US) device on selected patients in a remote setting would alter physician diagnosis and management. This was a prospective observational study of the affects of US on physician decision making deep in the Amazon jungle. A battery-operated Sonosite 180 Plus with 2 interchangeable transducers (4-7-MHz broadband intercavitary transducer and 2-5-MHz broadband abdominal transducer) was used. The patient population consisted of local tribal people. Two of the physicians on the team performed all US examinations. Team physicians requesting US examinations filled out a survey before and after the US examination. Before the US, the referring physician filled out a survey describing the patient's initial complaint, pertinent past medical history and physical findings, and an initial (pre-US) differential diagnosis and planned treatment with expected disposition. After the results of the US were reviewed with the referring physicians, the doctors were asked to fill out the remainder of the survey, allowing comparison of pre- and post-US differential diagnosis, treatment plan, and disposition. A total of 25 US studies were performed during this study (1 trauma US scan, 6 hepatobiliary studies, 5 transabdominal pelvic scans, 7 transvaginal pelvic studies, 3 renal studies, and 3 abdominal aortic scans). The monitor on the US unit experienced a rare failure shortly after being used at 17,000 ft and then 10 times at sea level, and no further US scans could be performed. US scan results dramatically altered the disposition of 7 patients, including 4 patients who avoided a potentially dangerous 2-day evacuation to more definitive medical care. Three patients were found to need rapid referral to the nearest clinic for surgical evaluation. When used in a remote location, portable US provides a significant benefit that can dramatically alter disposition and treatment.
