Selected AbstractsMultiwavelength Laser Treatment of Venous LakesDERMATOLOGIC SURGERY, Issue 12 2009MÓNICA RONCERO MD BACKGROUND Venous lakes (VLs) are common benign ectasias in the upper dermis, usually observed in older people. Different treatment strategies have been described as useful, such as cryosurgery, excision, and various types of laser. OBJECTIVE We report our experiences using a multiwavelength laser, which has not been previously described. PATIENTS AND METHODS Thirty-nine VLs in 30 patients were treated. Treatment with 595-nm pulsed-dye laser was conducted at 20 ms and 10 J/cm2, followed by 1,064-nm neodymium-doped yttrium aluminum garnet laser at 20 ms and 70 J/cm2. RESULTS Complete resolution was observed in 38 lesions (95%). No complications after treatment were noted. One case developed a small scar. CONCLUSIONS Multiwavelentgh laser (595 nm; 1,064 nm) provides a safe, fast, and effective option in the treatment of VLs. [source] Efficacy of combined cyclosporine A and ketoconazole treatment of anal furunculosisJOURNAL OF SMALL ANIMAL PRACTICE, Issue 5 2004T. O'Neill Cyclosporine A and ketoconazole were used as a combined therapy to treat 19 dogs with anal furunculosis. Complete resolution of all lesions was achieved in three to 10 weeks, but recurrences occurred in seven of the 19 dogs (36.8 per cent), with remission periods extending from one to six months for these dogs. Adverse effects of treatment included excessive hair loss, intermittent lethargy, vomiting and decreased appetite in some dogs, but none of the signs were considered serious. The results of treatment are comparable with, if not better than, the surgical alternatives. There is an approximate 70 per cent cost saving over the use of cyclosporine alone. [source] Ciprofloxacin-induced palatal tremorMOVEMENT DISORDERS, Issue 7 2007Yuk-Fai Cheung MRCP Abstract We describe an 84-year-old man with an unusual clinical presentation of palatal tremor in association with ciprofloxacin treatment. The patient had rhythmical movements not only of the soft palate but also of the face and trunk. Complete resolution of the symptoms occurred 2 days after discontinuation of ciprofloxacin and administration of sodium valproate. This is the first reported case of palatal tremor secondary to the use of ciprofloxacin. © 2007 Movement Disorder Society [source] Complete resolution of pulmonary Rhizopus oryzae infection with itraconazole treatment: more evidence of the utility of azoles for zygomycosisMYCOSES, Issue 3-4 2004D. P. Eisen Rhizopus oryzae; Zygomykose; Itraconazol Summary Zygomycosis often requires aggressive surgical and antifungal therapy. We report a non-neutropenic patient with myelodysplastic syndrome and iron overload receiving cytotoxic therapy who presented with pulmonary Rhizopus oryzae infection. This patient was cured through the use of itraconazole alone and the literature on the utility of azole antifungals for zygomycosis is reviewed.

We discuss the relationship of this eruption to other pustular disorders of infancy and hypothesize a mechanism that may initiate the eruption. [source] Complete resolution of a squamous cell carcinoma of the skin using intralesional 5-aminolevulinic acid photodynamic therapy intralesional PDT for SCCPHOTODERMATOLOGY, PHOTOIMMUNOLOGY & PHOTOMEDICINE, Issue 5 2010Eleni Sotiriou We present an 82-year-old female patient with a 2-year history of an infiltrative squamous cell carcinoma (SCC) on her right cheek. The patient was treated with one intralesional photodynamic therapy (PDT) session using 10% 5-aminolevulinic acid solution. We used red light by a non-coherent light source at a light dose of 100 J/cm2 and a fluency rate of 100 mW/cm2. Complete clinical and histological response was achieved 3 months after the treatment procedure. Cosmetic outcome was evaluated as fair. The patient remains disease free with the absence of any clinical sign of recurrence 16 months after PDT. Long-term follow-up is needed for assessment of recurrences. Optimization of the therapeutic protocol, as well as justification of our results in larger studies are needed in order to elicit safe conclusions. [source] Clinical Manifestations of Superior Semicircular Canal Dehiscence,THE LARYNGOSCOPE, Issue 10 2005Lloyd B. Minor MD Abstract Objectives/Hypotheses: To determine the symptoms, signs, and findings on diagnostic tests in patients with clinical manifestations of superior canal dehiscence. To investigate hypotheses about the effects of superior canal dehiscence. To analyze the outcomes in patients who underwent surgical repair of the dehiscence. Study Design: Review and analysis of clinical data obtained as a part of the diagnosis and treatment of patients with superior canal dehiscence at a tertiary care referral center. Methods: Clinical manifestations of superior semicircular canal dehiscence were studied in patients identified with this abnormality over the time period of May 1995 to July 2004. Criteria for inclusion in this series were identification of the dehiscence of bone overlying the superior canal confirmed with a high-resolution temporal bone computed tomography and the presence of at least one sign on physiologic testing indicative of superior canal dehiscence. There were 65 patients who qualified for inclusion in this study on the basis of these criteria. Vestibular manifestations were present in 60 and exclusively auditory manifestations without vestibular symptoms or signs were noted in 5 patients. Results: For the 60 patients with vestibular manifestations, symptoms induced by loud sounds were noted in 54 patients and pressure-induced symptoms (coughing, sneezing, straining) were present in 44. An air-bone on audiometry in these patients with vestibular manifestations measured (mean ± SD) 19 ± 14 dB at 250 Hz; 15 ± 11 dB at 500 Hz; 11 ± 9 dB at 1,000 Hz; and 4 ± 6 dB at 2,000 Hz. An air-bone gap 10 dB or greater was present in 70% of ears with superior canal dehiscence tested at 250 Hz, 68% at 500 Hz, 64% at 1,000 Hz, and 21% at 2,000 Hz. Similar audiometric findings were noted in the five patients with exclusively auditory manifestations of dehiscence. The threshold for eliciting vestibular-evoked myogenic potentials from affected ears was (mean ± SD) 81 ± 9 dB normal hearing level. The threshold for unaffected ears was 99 ± 7 dB, and the threshold for control ears was 98 ± 4 dB. The thresholds in the affected ear were significantly different from both the unaffected ear and normal control thresholds (P < .001 for both comparisons). There was no difference between thresholds in the unaffected ear and normal control (P = .2). There were 20 patients who were debilitated by their symptoms and underwent surgical repair of superior canal dehiscence through a middle cranial fossa approach. Canal plugging was performed in 9 and resurfacing of the canal without plugging of the lumen in 11 patients. Complete resolution of vestibular symptoms and signs was achieved in 8 of the 9 patients after canal plugging and in 7 of the 11 patients after resurfacing. Conclusions: Superior canal dehiscence causes vestibular and auditory symptoms and signs as a consequence of the third mobile window in the inner ear created by the dehiscence. Surgical repair of the dehiscence can achieve control of the symptoms and signs. Canal plugging achieves long-term control more often than does resurfacing. [source] Allergic contact dermatitis to basic red 46 occurring in an HIV-positive patientAUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 3 2006Nathan Curr SUMMARY A 41-year-old HIV-positive man presented with a 2-month history of a generalized pruritic rash, which had started on his feet. Patch testing made a diagnosis of allergic contact dermatitis to the textile dye basic red 46, likely to have been present in his dark-blue-coloured socks. Complete resolution of his symptoms occurred with avoidance of these socks. The patient had developed allergic contact dermatitis with a low CD4 T lymphocyte count of 361 cells/µl (normal range 410,1545 cells/µl). This raised the question of the level of CD4 count necessary for an individual to develop allergic contact dermatitis to an allergen, given its role in delayed hypersensitivity. It was concluded that a low CD4 count as a result of HIV infection does not decrease the ability of an individual to develop allergic contact dermatitis. Whereas the effector role in delayed type 4 hypersensitivity reactions is mediated by CD4 T lymphocytes, in allergic contact dermatitis it appears that CD4 T lymphocytes have the suppressor role, with CD8 T lymphocytes having the effector role. [source] Doxycycline-induced staining of permanent adult dentitionAUSTRALIAN DENTAL JOURNAL, Issue 4 2005E. Ayaslioglu Abstract Background: Doxycycline is the most effective antibiotic for managing brucellosis. Although it is relatively free from side effects, complications involving the skin, nails and teeth may rarely be encountered. Methods: Four patients with brucellosis developed yellow-brown discolouration of teeth following a 30,45 day course of doxycycline therapy during summer at a dose of 200mg/day. Results: All four patients were diagnosed as having doxycycline-induced staining of the permanent dentition. In all cases, the staining completely resolved and the teeth recovered their original colour following abrasive dental cleaning. Conclusions: These observations indicate that the incidence of staining of the permanent dentition, as a complication of doxycycline, may be much higher than the literature indicates, especially if treatment is administered during summer months. Fortunately, this complication is reversible and does not require termination of doxycycline therapy. Complete resolution following abrasive cleaning may suggest that an extrinsic mechanism within the dental milieu may be involved in its pathogenesis. Strict avoidance of sunlight exposure during high-dose, long-term doxycycline therapy might prevent the development of this complication. [source] Daclizumab, an efficient treatment for steroid-refractory acute graft- versus -host diseaseBRITISH JOURNAL OF HAEMATOLOGY, Issue 3 2006Pierre Bordigoni Summary In a phase II study, daclizumab was given as single second-line agent to 62 patients with steroid-refractory acute graft- versus -host disease (aGVHD). Complete resolution of aGVHD was achieved in 68·8% of patients. This response rate was significantly associated with a lower number of involved organs and smaller extent of skin involvement. The 4-year event-free survival (EFS) was 54·6%. Grade ,III aGVHD, ,2 involved organs at baseline and patient age >18 years were independently associated with lower EFS. Daclizumab could be a suitable alternative treatment for aGVHD, particularly when limited to the skin or gastrointestinal tract. [source] Effectiveness of erdosteine, a second generation mucolytic agent, in children with acute rhinosinusitis: a randomized, placebo controlled, double-blinded clinical studyACTA PAEDIATRICA, Issue 4 2010E Unuvar Abstract Aim:, To evaluate whether mucolytic agents have an adjuvant role with antibiotics in the treatment of children with rhinosinusitis. Methods:, Ninety-two children with rhinosinusitis were recruited for this randomized, placebo controlled, double-blinded clinical trial. Mean age was 8.5 ± 3.2 years. Erdosteine (5,8 mg/kg/day) was administered to 49 children, and 43 children received placebo. Changes in symptoms were recorded with the standard S5 scoring for 14 days. Complete resolution of symptoms on day 14 was considered to be clinical improvement. Results:, Eighty-one participants completed the study. Forty-one were in the treatment group and 40 in the placebo group. The average S5 scoring value at the onset of study was 11.0 in treatment group and 12.1 in placebo group. On day 14, mean scores were 3.1 in the treatment group and 2.8 in the placebo group. Complete improvement was 78% in the treatment group and 74.4% in the placebo group. There was no significant difference between the groups. There were no clinically detected serious side effects or complications in both groups. Conclusion:, Use of erdosteine as a mucolytic agent in children with acute rhinosinusitis does not directly affect the success of treatment.

Acyclovir (15 mg/kg/d for 10 d) was administered for severe genitourinary symptoms. The CSF culture was positive for HSV type 2. Conclusion: Complete resolution of all symptoms demonstrates that, as in adults, HSV-2 meningitis does not require high-dose or prolonged acyclovir therapy. [source] ENDOSCOPIC OCCLUSION OF CYSTIC DUCT USING N -BUTYL CYANOACRYLATE FOR POSTOPERATIVE BILE LEAKAGEDIGESTIVE ENDOSCOPY, Issue 4 2010Eric K. Ganguly Bile leak after cholecystectomy is well described, with the cystic duct remnant the site of the leak in the majority of cases. Endoscopic retrograde cholangiopancreatography (ERCP) with biliary stent placement has a high success rate in such cases. When ERCP fails, options include surgery, and percutaneous and endoscopic transcatheter occlusion of the site of bile leak. Here, we describe a case of endoscopic transcatheter occlusion of a persistent cystic duct bile leak after cholecystectomy using N -butyl cyanoacrylate glue. A 51-year-old man had persistent pain and bilious drainage following a laparoscopic cholecystectomy. The bile leak persisted after endoscopic placement of a biliary stent for a confirmed cystic duct leak. A repeat ERCP was carried out and the cystic duct was occluded with a combination of angiographic coils and N -butyl cyanoacrylate glue. The patient's pain and bilious drainage resolved. A follow-up cholangiogram confirmed complete resolution of the cystic duct leak and a patent common bile duct. [source] SPONTANEOUS COLONIC HEMATOMA: ENDOSCOPIC APPEARANCEDIGESTIVE ENDOSCOPY, Issue 2 2007Marcus Martins Dos Santos Intramural colonic hematoma is a rare complication of anticoagulation therapy. We report a patient under therapy with acetylsalicylic acid, low-molecular-weight heparin and clopidogrel for unstable angina, who presented with massive lower gastrointestinal bleeding secondary to spontaneous intramural colonic hematoma, with unremarkable coagulation tests. Diagnosis was promptly made by colonoscopy, and the patient was successfully managed with a conservative approach, with complete resolution of symptoms after 7 days. This is the first report of spontaneous intramural colonic hematoma presumed to be related to acetylsalicylic acid, enoxaparin and clopidogrel. [source] ORIGINAL INVESTIGATIONS: Different Clinical Features of Aortic Intramural Hematoma Versus Dissection Involving the Descending Thoracic AortaECHOCARDIOGRAPHY, Issue 8 2005Mariano Falconi M.D. Objective: The objective of this study is to test the hypothesis that the absence of flow communication in aortic intramural hematoma (IMH) involving the descending aorta may have a different clinical course compared with aortic dissection (AD). Methods: We prospectively evaluated clinical and echocardiographic data in AD (76 patients) and IMH (27 patients) of the descending thoracic aorta. Results: Patients did not differ with regard to age, gender, or clinical presentation. IMH and AD had the same predictors of complications at follow-up: aortic diameter (>5 cm) at diagnosis and persistent back pain. Surgical treatment was more frequently selected in AD (39% vs. 22%, P < 0.01) and AD patients who underwent surgical treatment had higher mortality than those with IMH (36% vs. 17%, P < 0.01). There was no difference in mortality with medical treatment (14% in AD vs. 19% in IMH, P = 0.7). During follow-up, of 23 patients with IMH, 11 (47%) showed complete resolution or regression, 6 (26%) increased the diameter of the descending aorta, and typical AD developed in 3 patients (13%). No changes occurred in 14% of the group. Three-year survival rate did not show significant differences between both groups (82 ± 6% in IMH vs. 75 ± 7% in AD, P = 0.37). Conclusion: IMH of the descending thoracic aorta has a relatively frequent rate of complications at follow-up, including dissection and aneurysm formation. Medical treatment with very frequent imaging and timed elective surgery in cases with complications allows a better patient management. [source] Capillary zone electrophoresis with a dynamic double coating for analysis of carbohydrate-deficient transferrin in human serum: Impact of resolution between disialo- and trisialotransferrin on reference limitsELECTROPHORESIS, Issue 24 2003Christian Lanz Abstract Capillary electrophoresis with a dynamic double coating formed by charged polymeric reagents represents a very effective tool for the separation of iron-saturated transferrin (Tf) isoforms and thus the determination of carbohydrate-deficient transferrin (CDT) in human serum. The resolution between di- and trisialo-Tf is dependent on the applied voltage and capillary temperature. With a 50 ,m inside diameter (ID) capillary of about 60 cm total length mounted into the P/ACE MDQ, 28 kV and 40°C, the resolution of the two Tf isoforms is shown to be between 1.0 and 1.4, whereas with reduced voltage and/or temperature, increased resolution at the expense of elongated run times is observed. Best data with complete resolution (Rs , 1.4) are obtained at 20 kV and 30°C. For the determination of CDT in serum, incomplete separation of di- and trisialo-Tf is demonstrated to have an impact on the reference limits. Analysis of the sera of 54 healthy individuals with no or moderate alcohol consumption and using valley-to-valley peak integration, the upper (lower) reference limits for CDT in relation to total Tf at the two power levels are 1.33 (0.52) and 1.57 (0.81)%, respectively, representing intervals that are significantly different (P < 0.001). Furthermore, the reference intervals are shown to be strongly dependent on the peak integration approach used. Valley-to-valley peak integration should only be employed for conditions with complete resolution between disialo- and trisialo-Tf. [source] Large-volume sample stacking combined with separation by 2-hydroxypropyl-,-cyclodextrin for analysis of isoxyzolylpenicillins by capillary electrophoresisELECTROPHORESIS, Issue 17 2003Zhiwei Zhu Abstract A simple, quick and sensitive capillary electrophoretic technique has been developed for the pharmaceutical analysis of isoxazolylpenicillins (oxacillin, cloxacillin and dicloxacillin) at trace levels for the first time. This method comprises large-volume sample stacking using the electroosmotic flow (EOF) pump (LVSEP), separation using 2-hydroxypropyl-,-cyclodextrin (HP-,-CD) as selective complex-forming background electrolyte additive, and direct UV detection. A complete resolution was achieved in the optimal background electrolyte containing 5.2 mM HP-,-CD. LVSEP was successfully applied in their determinations to improve the sensitivity, where the EOF in the buffer zone was suppressed by using an acidic buffer with pH 3.6. The detection limits of the current technique were found to be 2.0 ,g/L for each of the isoxazolylpenicillins based on the signal-to-noise ratio of 3. The curves of peak response versus concentration were linear from 5.0 to 400.0 ,g/L with regression coefficients of 0.9982, 0.9986 and 0.9976, respectively. The interaction of isoxazolylpenicillins with HP-,-CD was discussed. The association constants for complexes of HP-,-CD with isoxazolylpenicillins were determined by electrophoretic method. The obtained association constants were 27.3, 34.9, and 48.5 M,1, respectively, being proportional to their hydrophobic properties and steric hindrances. A simple and easy-manipulative sample preparation method was developed and validated by analyzing commercially available milk samples. It was found that with current sample preparation process and instrumentation system, 0.1 mL of milk sample is enough for the analysis of isoxazolylpenicillins to meet European Union (EU) guideline of 30 ,g/kg. [source] Diagnosis at dusk: Malignant hypertension and phaeochromocytoma in a 6-year-old girlEMERGENCY MEDICINE AUSTRALASIA, Issue 1 2008John Corcoran Abstract Phaeochromocytoma is a rare catecholamine-secreting tumour that may arise at any age, but is particularly unusual in childhood. The case of a 6-year-old girl who presented with a prolonged history of general malaise, headaches and abdominal pain is reported. On examination, she was noted to have malignant hypertension. Subsequent imaging of the abdomen demonstrated a left adrenal mass, with the diagnosis of phaeochromocytoma being confirmed by serial raised urinary metanephrines. Sympathetic blockade was established prior to definitive surgical treatment, resulting in complete resolution of the patient's symptoms and hypertension. Genetic screening of the family has since identified a previously undocumented missense mutation in the patient's VHL gene. The case raises the importance of routine measurement of blood pressure in all paediatric patients regardless of age, presentation or other factors. [source] Failure of intramuscular antivenom in Red-back spider envenomingEMERGENCY MEDICINE AUSTRALASIA, Issue 4 2002Geoffrey K Isbister Abstract Four cases of Red-back spider envenoming are reported in which there was minimal response to intramuscular antivenom. Intravenous antivenom was then administered in each case with almost complete resolution of symptoms. All cases were followed up to confirm the effect of treatment. This failure of intramuscular Red-back antivenom raises the question of its efficacy. There has been no controlled trial to prove that intramuscular Red-back antivenom is effective and animal work with other antivenoms has demonstrated the intramuscular formulation to have delayed and incomplete effects. Controlled studies should be undertaken to establish the effectiveness of intravenous and intramuscular Red-back antivenom. [source] Vasoconstriction as the Etiology of Hypercalcemia-induced SeizuresEPILEPSIA, Issue 5 2004Tsung-Hua Chen Summary: Purpose: Reversible cerebral vasoconstriction has been hypothesized to be the etiology of seizures due to hypercalcemia, but angiographic studies documenting vasoconstriction have not previously been available. Methods: We present a 43-year-old woman who had frequent seizures that later evolved to status epilepticus with marked hypercalcemia at the time of the seizures. Results: Magnetic resonance imaging (MRI) of the patient's brain revealed high signal changes in T2 -weighted imaging, fluorescence-attenuated inversion recovery (FLAIR), and diffusion-weighted imaging (DWI) over the bilateral occipital and thalamic areas. Cerebral angiography showed blood vessels narrowing, disappearing altogether over the right posterior cerebral artery (PCA) branch, which is compatible with vasoconstriction. Vasoconstriction caused the MRI high signal in the occipital area, which was associated with subsequent periodic lateralized epileptic discharges. The patient's clinical condition improved with management of seizures and hypercalcemia. A second brain MRI 2 weeks later revealed complete resolution of the high-signal lesions. Follow-up cerebral angiography study also showed total recovery of vasoconstriction. Conclusions: The sequence of events suggests the hypothesis that reversible cerebral vasoconstriction may play a role in hypercalcemia-induced seizures. [source] Conservative physiotherapeutic management of chronic haematomata and haemophilic pseudotumours: case study and comparison to historical managementHAEMOPHILIA, Issue 1 2009A. I. D'YOUNG Summary., A conservative, non-operative physiotherapeutic regime for the management of chronic haematomata and pseudotumours in patients suffering from haemophilia is described in this article. Two cases are described where physiotherapy treatment is applied to large masses at the shoulder and femur respectively, where therapy commenced within the first 6 months following onset. These are presented relative to a case that was managed over a much longer period without early physiotherapy input, and the relative outcomes are examined. While both the early physiotherapy-managed cases showed a complete resolution at follow-up examination, the more established chronic pseudotumour required surgical excision, with significant residual muscle contractility, length and strength issues noted on clinical and magnetic resonance imaging reviews. No adverse symptoms or haemostatic issues were reported in response to this less invasive treatment regime by either patient in the two conservative physiotherapy cases. [source] Cervical spondylodiscitis: A rare complication after phonatory prosthesis insertionHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 1 2006Andrea Bolzoni MD Abstract Background. Tracheoesophageal puncture has excellent voice rehabilitation after total laryngectomy. However, despite its easy insertion and use, severe complications have been reported. Methods. We report a case of cervical spondylodiscitis, occurring in a 67-year-old woman submitted to phonatory prosthesis insertion. After 1 month, she complained of severe cervicalgia associated with fever. Spondylodiscitis involving C6, C7, and the intervening vertebral disk with medullary compression was detected by means of imaging studies. Results. A right cervicotomy with drainage of necrotic tissue was performed, and a deepithelialized fasciocutaneous deltopectoral flap was interposed between the neopharynx-esophagus and the prevertebral fascia to protect the neurovascular axis. MR performed 1 month later showed a complete resolution of the infectious process. Conclusions. Severe neck pain after tracheoesophageal puncture should alert the physician about the possibility of a cervical spondylodiscitis. MR is the most useful imaging technique for preoperative and postoperative evaluation. When neurologic symptoms are detected, surgical exploration of the neck is mandatory. © 2005 Wiley Periodicals, Inc.

Chang MD Abstract Background The purpose of this study was to assess the effectiveness of free tissue transfer for treatment of advanced mandibular osteoradionecrosis (ORN) in head and neck cancer patients. Methods We reviewed 29 patients who were treated for advanced mandibular ORN by radical resection and reconstruction with free flaps at our institution. All patients had either failed to respond to conservative treatment, including hyperbaric oxygen therapy and debridement or had pathological fracture due to ORN. Results Twenty-four vascularized bone (17 fibula, five iliac, and two scapula), four rectus abdominis myocutaneous, and one radial forearm fasciocutaneous free flaps were used. The complications occurred in 6 of 29 patients (21%). A total of four flaps (14%) were lost. The mean follow-up was 2 years 9 months. All patients had complete resolution of ORN symptoms. No evidence of ORN recurrence was observed in any patient. Conclusion For advanced osteoradionecrosis of the mandible, radical resection followed by reconstruction using free flap provides a reliable means of obtaining good wound healing with acceptable aesthetic and functional results. © 2001 John Wiley & Sons, Inc.

[source] Electrical Stimulation of Sphenopalatine Ganglion for Acute Treatment of Cluster HeadachesHEADACHE, Issue 7 2010Mehdi Ansarinia MD (Headache 2010;50:1164-1174) Introduction., Cluster headaches (CH) are primary headaches marked by repeated short-lasting attacks of severe, unilateral head pain and associated autonomic symptoms. Despite aggressive management with medications, oxygen therapy, nerve blocks, as well as various lesioning and neurostimulation therapies, a number of patients are incapacitated and suffering. The sphenopalatine ganglion (SPG) has been implicated in the pathophysiology of CH and has been a target for blocks, lesioning, and other surgical approaches. For this reason, it was selected as a target for an acute neurostimulation study. Methods., Six patients with refractory chronic CH were treated with short-term (up to 1 hour) electrical stimulation of the SPG during an acute CH. Headaches were spontaneously present at the time of stimulation or were triggered with agents known to trigger clusters headache in each patient. A standard percutaneous infrazygomatic approach was used to place a needle at the ipsilateral SPG in the pterygopalatine fossa under fluoroscopic guidance. Electrical stimulation was performed using a temporary stimulating electrode. Stimulation was performed at various settings during maximal headache intensity. Results., Five patients had CH during the initial evaluation. Three returned 3 months later for a second evaluation. There were 18 acute and distinct CH attacks with clinically maximal visual analog scale (VAS) intensity of 8 (out of 10) and above. SPG stimulation resulted in complete resolution of the headache in 11 attacks, partial resolution (>50% VAS reduction) in 3, and minimal to no relief in 4 attacks. Associated autonomic features of CH were resolved in each responder. Pain relief was noted within several minutes of stimulation. Conclusion., Sphenopalatine ganglion stimulation can be effective in relieving acute severe CH pain and associated autonomic features. Chronic long-term outcome studies are needed to determine the utility of SPG stimulation for management and prevention of CH. [source] Orthostatic Headaches in the Syndrome of the Trephined: Resolution Following CranioplastyHEADACHE, Issue 7 2010Bahram Mokri MD Objective., To draw attention to the syndrome of the trephined as a potential cause for orthostatic headaches without cerebrospinal fluid (CSF) leak. Background., Orthostatic headaches typically result from CSF leaks but sometimes may occur in conditions without any evidence of CSF leakage. Methods., A 37-year-old right-handed woman became comatose after a motor vehicle accident with cerebral contusions and massive left cerebral edema. A large frontoparietal craniectomy was carried out. In 5 months, she made good neurologic recovery. Freeze-preserved bone flap was placed back. In several weeks she was functionally near normal. Two years later, she began to complain of orthostatic headache and gradually additional manifestations appeared including progressive gait unsteadiness, imprecise speech, cognitive difficulties, and an increasing left hemiparesis along with progressive sinking of the skull defect and shift of the midline and ventricular distortion. She underwent removal of resorptive sinking bone flap and construction of an acrylic cranioplasty. Results., At 6-month follow-up, there was complete resolution of the orthostatic headaches, remarkable neurologic improvement along with resolution of midline shift and ventricular distortion. Conclusion., The syndrome of the trephined is yet another cause of orthostatic headaches without CSF leak. [source] Favorable Response to Analgesics Does Not Predict a Benign Etiology of HeadacheHEADACHE, Issue 6 2008Jennifer V. Pope MD Background., Distinguishing between primary and secondary headaches (HAs) is essential for the safe and effective management of patients with HA. A favorable response to analgesics may be observed with both classes of HAs and therefore is not a good predictor of who needs further evaluation. Objective., To systematically review the data that a favorable response to analgesics including triptans should not be used to exclude a serious secondary cause of HA. Design., PubMed search of English-language articles between 1980 and 2007 and reference lists of these articles. Two authors independently reviewed articles for study results and quality. Inclusion was based on 100% agreement between authors. We included articles that described secondary HAs as (1) having a favorable response to analgesics and/or (2) having a favorable response to sumatriptan. Of the 548 studies identified by our search strategy, 18 were included in our final analysis. Results., Seven of the 18 studies found that 46/103 patients (44%) described a significant or complete resolution of secondary HA from medications such as anti-emetics and nonsteroidal anti-inflammatory drugs (NSAIDs). Eleven of the 18 articles including 25/25 patients (100%) described a significant or complete resolution of secondary HA from sumatriptan, a serotonin 5HT agonist. Conclusions., A favorable response to analgesics including triptans should not be used to exclude a serious secondary cause of HA. [source] Outpatient Intravenous Dihydroergotamine for Refractory Cluster HeadacheHEADACHE, Issue 3 2004E. Magnoux MD Objective.,To evaluate the efficacy and safety of outpatient intravenous dihydroergotamine (DHE) for treatment of refractory cluster headache. Method.,Medical records were retrospectively reviewed of all patients with cluster headache who received outpatient intravenous DHE for treatment of refractory cluster headache between January 1992 and May 2000. Results.,One hundred four treatments were identified in 70 patients. There were 7 dropouts. Of the 97 completed treatments, 60 were for episodic cluster headache and 37 were for chronic cluster headache. Results for all treatments showed complete resolution of pain during the intravenous phase at 1 month in 61 (63%) of 97 cases, partial resolution in 13 cases (15%), and failure in 23 cases (24%). For the treatment of episodic cluster headache, there was complete resolution in 44 (73%) of 60 cases, partial resolution in 9 cases (13%), and failure in 7 cases (12%). For treatment of chronic cluster headache, there was complete resolution in 17 (46%) of the 37 cases, partial resolution in 4 cases (11%), and 16 failures (43%). As regards side effects and safety, the treatment triggered chest pain suspected of being vasospastic angina in 1 patient on day 7 of the treatment, when she was in the subcutaneous phase. Two patients dropped out due to fear of the injection, 1 because of palpitations, 1 because of chest tightness, and 2 others because of leg cramps, nausea, and diarrhea. Conclusions.,Outpatient intravenous DHE is a safe treatment. It is useful for refractory cluster headache, is more effective for the episodic form than the chronic form, and has a rapid onset of action. It did not change the evolution of the episodic form, but it did appear to induce remission in the chronic form or transform it to the episodic form. We advance a hypothesis to explain this. [source] Chylous effusions complicating lymphoma: a serious event with octreotide as a treatment optionHEMATOLOGICAL ONCOLOGY, Issue 2 2003J. Evans Abstract Chylous effusions have an identical appearance to milk and occur when the thoracic duct is blocked. Since chyle represents direct absorption of fat from the small intestine lacteals, it is rich in fat, calories, vitamins and immunoglobulins. Drainage of this milk-like fluid from any cavity (chest or abdomen) results in rapid weight loss and profound cachexia. The recognition of this milk-like fluid as chyle is urgent for the implementation of the correct treatment. In adults, lymphoma is one of the commonest malignancies to cause blockages in the thoracic duct. Once the diagnosis is made, conservative treatment with strict dietary adjustment often fails to prevent weight loss or resolve the underlying cause. Since the condition is uncommon, no guidelines exist. Many surgeons recommend early surgical intervention before the patient becomes too weak. Surgery may also fail. We report the case of a 62-year-old man with chylous effusions and a weight loss of 30,kg. The nature of the effusion was unrecognized for the first 16 weeks. Upon diagnosis, dietary adjustment was made and a lymphangiogram organized with a view to surgery. Literature searches revealed two cases in which somatostatin was used after surgical procedures failed. We therefore used octreotide (a synthetic analogue of somatostatin). We report complete resolution of the condition within 72,h leading to the resumption of a normal diet and discharge within 2 weeks. Copyright © 2003 John Wiley & Sons, Ltd. [source] Prevention of hemodialysis-related muscle cramps by intradialytic use of sequential compression devices: A report of four casesHEMODIALYSIS INTERNATIONAL, Issue 3 2004Muhammad Ahsan Background:, Hemodialysis (HD)-related lower extremity (LE) muscle cramps are a common cause of morbidity in end-stage renal disease patients on maintenance HD. Numerous pharmacologic and physical measures have been tried with variable success rates. Methods:, Sequential compression devices (SCD) improve venous return (VR) and are commonly used to prevent LE deep venous thrombosis in hospitals. We hypothesized that LE cramps are triggered by stagnant venous flow during HD and are preventable by improving VR. We prospectively studied four adult patients (mean age 61 ± 14 years) on thrice-weekly HD who experienced two or more episodes of LE cramping weekly in the month before the study. SCD were applied before each HD on both legs and compressions were intermittently applied at 40 mmHg during treatment. Results:, All four patients reported complete resolution of cramping during the study period that lasted 1 month or 12 consecutive dialysis treatments. Conclusion:, Application of SCD to LE may prevent the generation of LE HD-related cramping in a select group of patients. Larger, controlled studies are needed to establish the utility of this noninvasive alternative for the prevention of LE HD-related cramps. [source] | ||||||||||||||||||||||||||||||||||||||||||||||
