Paresthesia is defined as an alteration in local sensibility, associated with numbness, tingling, or unpleasant sensations caused by nerve lesions or irritation. It can be temporary or permanent. The treatment protocol for facial paresthesia is primarily based on the use of drugs and implant removal, which may not be completely effective or may require other risk exposure when there is no spontaneous regression. However, other therapeutic modalities such as acupuncture can be used. The aim of...

Concordant paresthesia coverage is an independent predictor of pain relief following spinal cord stimulation (SCS). Using aggregate data, our objective is to produce a map of paresthesia coverage as a function of electrode location in SCS. This retrospective analysis used x-rays, SCS programming data, and paresthesia coverage maps from the EMPOWER registry of SCS implants for chronic neuropathic pain. Spinal level of dorsal column stimulation was determined by x-ray adjudication and active cathodes in patient programs. Likelihood of paresthesia coverage was determined as a function of stimulating electrode location. Segments of paresthesia coverage were grouped anatomically. Fisher's exact test was used to identify significant differences in likelihood of paresthesia coverage as a function of spinal stimulation level. In the 178 patients analyzed, the most prevalent areas of paresthesia coverage were buttocks, anterior and posterior thigh (each 98%), and low back (94%). Unwanted paresthesia at the ribs occurred in 8% of patients. There were significant differences in the likelihood of achieving paresthesia, with higher thoracic levels (T5, T6, and T7) more likely to achieve low back coverage but also more likely to introduce paresthesia felt at the ribs. Higher levels in the thoracic spine were associated with greater coverage of the buttocks, back, and thigh, and with lesser coverage of the leg and foot. This paresthesia atlas uses real-world, aggregate data to determine likelihood of paresthesia coverage as a function of stimulating electrode location. It represents an application of "big data" techniques, and a step toward achieving personalized SCS therapy tailored to the individual's chronic pain. © 2017 International Neuromodulation Society.

A patient with failed back surgery syndrome reported paresthesia in his hands and arms during a spinal cord stimulation (SCS) screening trial with a low thoracic electrode. The patient's severe thoracic stenosis necessitated general anesthesia for simultaneous decompressive laminectomy and SCS implantation for chronic use. Use of general anesthesia gave the authors the opportunity to characterize the patient's unusual distribution of paresthesia. During SCS implantation, they recorded SCS-evoked antidromic potentials at physiologically relevant amplitudes in the legs to guide electrode placement and in the arms as controls. Stimulation of the dorsal columns at T-8 evoked potentials in the legs (common peroneal nerves) and at similar thresholds, consistent with the sensation of paresthesia in the arms, in the right ulnar nerve. The authors' electrophysiological observations support observations by neuroanatomical specialists that primary afferents can descend several (in this case, at least 8) vertebral segments in the spinal cord before synapsing or ascending. This report thus confirms a physiological basis for unusual paresthesia distribution associated with thoracic SCS.

Paresthesia is a burning or prickling sensation or partial numbness, resulting from neural injury. The symptoms can vary from mild neurosensory dysfunction to total loss of sensation in the innervated area. Only a few cases have described apical periodontitis to be the etiological factor of impaired sensation in the area innervated by the inferior alveolar and mental nerves. The aim of the present paper is to report a case of periapical lesion-induced paresthesia in the innervation area of the mental nerve, which was successfully treated with endodontic retreatment.

Lesogaberan, a γ-aminobutyric acid (GABA)B receptor agonist, was developed for the treatment of gastroesophageal reflux disease in patients with a partial response to proton pump inhibitor therapy. A high prevalence of paresthesia was observed in healthy individuals after dosing with lesogaberan in early-phase clinical trials. The aim of this review was to gain further insight into paresthesia caused by lesogaberan by summarizing the relevant preclinical and clinical data. This study was a narrative review of the literature and unpublished data. The occurrence of paresthesia may depend on the route or rate of drug administration; several studies were conducted to test this hypothesis, and formulations were developed to minimize the occurrence of paresthesia. Phase I clinical studies showed that, in healthy individuals, paresthesia occurred soon after administration of lesogaberan in a dose-dependent manner regardless of the route of administration. The occurrence of paresthesia could be decreased by fractionating the dose or reducing the rate of administration. These findings suggest that the initial rate of absorption plays an important part in the development of paresthesia. Modified-release formulations minimize the occurrence of paresthesia while retaining the anti-reflux activity of the drug, as measured by esophageal pH and the number of transient lower esophageal sphincter relaxations. The development of lesogaberan was halted because the effect on gastroesophageal reflux disease symptoms observed in Phase II studies was not considered clinically meaningful in the target patient population. Nevertheless, it is an example of successful formulation development designed to minimize the occurrence of a compound's adverse effect while retaining its pharmacodynamic action.

Whenever endodontic therapy is performed on mandibular posterior teeth, damage to the inferior alveolar nerve or any of its branches is possible. Acute periapical infection in mandibular posterior teeth may also sometimes disturb the normal functioning of the inferior alveolar nerve. The most common clinical manifestation of these insults is the paresthesia of the inferior alveolar nerve or mental nerve paresthesia. Paresthesia usually manifests as burning, prickling, tingling, numbness, itch...

Several studies have suggested that the likelihood of paresthesia may depend on the local anesthetic used. The purpose of this study was to determine if the type of local anesthetic administered had any effect on reports of paresthesia in dentistry in the United States. The authors obtained reports of paresthesia involving dental local anesthetics during the period from November 1997 through August 2008 from the U.S. Food and Drug Administration Adverse Event Reporting System. They used chi(2) analysis to compare expected frequencies, on the basis of U.S. local anesthetic sales data, with observed reports of oral paresthesia. During the study period, 248 cases of paresthesia occurring after dental procedures were reported. Most cases (94.5 percent) involved mandibular nerve block. The lingual nerve was affected in 89.0 percent of cases. Reports involving 4 percent prilocaine and 4 percent articaine were 7.3 and 3.6 times, respectively, greater than expected (chi(2), P paresthesia occurs more commonly after use of 4 percent local anesthetic formulations. These findings are consistent with those reported in a number of studies from other countries. Until further research indicates otherwise, dentists should consider these results when assessing the risks and benefits of using 4 percent local anesthetics for mandibular block anesthesia.

Paresthesia-dominant and pain-dominant subgroups have been noted in carpal tunnel syndrome (CTS), a peripheral neuropathic disorder characterized by altered primary somatosensory/motor (S1/M1) physiology. We aimed to investigate whether brain morphometry dissociates these subgroups. Subjects with CTS were evaluated with nerve conduction studies, whereas symptom severity ratings were used to allocate subjects into paresthesia-dominant (CTS-paresthesia), pain-dominant (CTS-pain), and pain/paresthesia nondominant (not included in further analysis) subgroups. Structural brain magnetic resonance imaging data were acquired at 3T using a multiecho MPRAGE T1-weighted pulse sequence, and gray matter cortical thickness was calculated across the entire brain using validated, automated methods. CTS-paresthesia subjects demonstrated reduced median sensory nerve conduction velocity (P = 0.05) compared with CTS-pain subjects. In addition, cortical thickness in precentral and postcentral gyri (S1/M1 hand area) contralateral to the more affected hand was significantly reduced in CTS-paresthesia subgroup compared with CTS-pain subgroup. Moreover, in CTS-paresthesia subjects, precentral cortical thickness was negatively correlated with paresthesia severity (r(34) = -0.40, P = 0.016) and positively correlated with median nerve sensory velocity (r(36) = 0.51, P = 0.001), but not with pain severity. Conversely, in CTS-pain subjects, contralesional S1 (r(9) = 0.62, P = 0.042) and M1 (r(9) = 0.61, P = 0.046) cortical thickness were correlated with pain severity, but not median nerve velocity or paresthesia severity. This double dissociation in somatotopically specific S1/M1 areas suggests a neuroanatomical substrate for symptom-based CTS subgroups. Such fine-grained subgrouping of CTS may lead to improved personalized therapeutic approaches, based on superior characterization of the linkage between peripheral and central neuroplasticity.

The aim of this study was to compare the efficacy of CT and MRI in evaluating orofacial pain and paresthesia. A total of 96 patients with orofacial pain and/or paresthesia were included in this study. The patients who underwent CT and/or MRI examinations were assessed, and the efficacy of CT and/or MRI examinations in detecting the causative disease of the orofacial pain and paresthesia was evaluated. Seventy (72.9%) of 96 patients underwent CT and/or MRI examinations. Whereas CT examinations detected 2 diseases (4.5%) in 44 tests, 13 diseases (37.1%) were detected in 35 MRI examinations. Seven (53.8%) of 13 diseases, which were detected by MRI, were found in elderly patients. A high percentage of patients, who claimed orofacial pain and paresthesia, have other diseases in their brain, especially in elderly patients, and MRI is more useful than CT for evaluating these patients.

This report describes a rare case of femoral nerve paresthesia caused by an acetabular paralabral cyst of the hip joint. A 68-year-old woman presented with a 6-month history of right hip pain and paresthesia along the anterior thigh and radiating down to the anterior aspect of the knee. Radiography showed osteoarthritis with a narrowed joint space in the right hip joint. Magnetic resonance imaging showed a cyst with low T1- and high T2-weighted signal intensity arising from a labral tear at the anterior aspect of the acetabulum. The cyst was connected to the joint space and displaced the femoral nerve to the anteromedial side. The lesion was diagnosed as an acetabular paralabral cyst causing femoral neuropathy. Because the main symptom was femoral nerve paresthesia and the patient desired a less invasive procedure, arthroscopic labral repair was performed to stop synovial fluid flow to the paralabral cyst that was causing the femoral nerve paresthesia. After surgery, the cyst and femoral nerve paresthesia disappeared. At the 18-month follow-up, the patient had no recurrence. There have been several reports of neurovascular compression caused by the cyst around the hip joint. To the authors' knowledge, only 3 cases of acetabular paralabral cysts causing sciatica have been reported. The current patient appears to represent a rare case of an acetabular paralabral cyst causing femoral nerve paresthesia. The authors suggest that arthroscopic labral repair for an acetabular paralabral cyst causing neuropathy can be an option for patients who desire a less invasive procedure.

Carpal tunnel syndrome has been associated with sleep position preferences. The aim of this study is to assess self-reported nocturnal paresthesias and sleeping position in participants with and without carpal tunnel syndrome diagnosis to further clinical knowledge for preventive and therapeutic interventions. A cross-sectional survey study of 396 participants was performed in young adults, healthy volunteers, and a patient population. Participants were surveyed on risk factors for carpal tunnel syndrome, nocturnal paresthesias, and sleep preferences. Binary logistic regression analysis was performed comparing participants with rare and frequent nocturnal paresthesias. Subanalyses for participants without carpal tunnel syndrome under and over 21 years of age were performed on all factors significantly associated with subclinical compression neuropathy in the overall population. Thirty-three percent of the study population experienced nocturnal paresthesias at least weekly. Increased body mass index ( P < .001) and sleeping with the wrist flexed ( P = .030) were associated with a higher frequency of nocturnal paresthesias. Side sleeping was associated with less frequent nocturnal symptoms ( P = .003). In participants without carpal tunnel syndrome, subgroup analysis illustrated a relationship between nocturnal paresthesias and wrist position. In participants with carpal tunnel syndrome, sleeping on the side had a significantly reduced frequency of nocturnal paresthesias. This study illustrates nocturnal paresthesias in people without history of carpal tunnel syndrome including people younger than previously reported. In healthy patients with upper extremity subclinical compression neuropathy, sleep position modification may be a useful intervention to reduce the frequency of nocturnal symptoms prior to developing carpal tunnel syndrome.

The objective of the study was to investigate how patients with sciatica due to disc herniation rate the bothersomeness of paresthesia and weakness as compared to leg pain, and how these symptoms are associated with socio-demographic and clinical characteristics. A cross-sectional study was conducted on 411 patients with clinical signs of radiculopathy. Items from the Sciatica Bothersomeness Index (0 = none to 6 = extremely) were used to establish values for paresthesia, weakness and leg pain. Associations with socio-demographic and clinical variables were analyzed by multiple linear regression. Mean scores (SD) were 4.5 (1.5) for leg pain, 3.4 (1.8) for paresthesia and 2.6 (2.0) for weakness. Women reported higher levels of bothersomeness for all three symptoms with mean scores approximately 10% higher than men. In the multivariate models, more severe symptoms were associated with lower physical function and higher emotional distress. Muscular paresis explained 19% of the variability in self-reported weakness, sensory findings explained 10% of the variability in paresthesia, and straight leg raising test explained 9% of the variability in leg pain. In addition to leg pain, paresthesia and weakness should be assessed when measuring symptom severity in sciatica.

The present study describes a case of endodontic sealer (AH Plus) penetration within and along the mandibular canal from the periapical zone of a lower second molar after endodontic treatment. The clinical manifestations comprised anesthesia of the left side of the lower lip, paresthesia and anesthesia of the gums in the third quadrant, and paresthesia and anesthesia of the left mental nerve, appearing immediately after endodontic treatment. The paresthesia and anesthesia of the lip and gums were seen to decrease, but the mental nerve paresthesia and anesthesia persisted after 3.5 years. This case illustrates the need to expend great care with all endodontic techniques when performing nonsurgical root canal therapy, especially when the root apices are in close proximity to vital anatomic structures such as the inferior alveolar canal.

To determine the incidence of paresthesia during lumbar puncture performed with the patient in different positions. A single-blind prospective study of patients scheduled for elective cesarean section, randomized to 3 groups. In group 1 patients were seated in the direction of the long axis of the table, with heels resting on the table. In group 2 they were seated perpendicular to the long axis of the table, with legs hanging from the table. In group 3 they were in left lateral decubitus position. Lumbar punctures were performed with a 27-gauge Whitacre needle. One hundred sixty-eight patients (56 per group) were enrolled. Paresthesia occurred most often in group 3 (P = .009). We observed no differences in blood pressure after patients moved from decubitus position to the assigned position. Nor did we observe between-group differences in blood pressure according to position taken during puncture. Puncture undertaken with the patient seated, heels on the table and knees slightly bent, is associated with a lower incidence of paresthesia than puncture performed with the patient seated, legs hanging from the table. Placing the patient's heels on the table requires hip flexion and leads to anterior displacement of nerve roots in the dural sac. Such displacement would increase the nerve-free zone on the posterior side of the sac, thereby decreasing the likelihood of paresthesia during lumbar puncture. A left lateral decubitus position would increase the likelihood of paresthesia, possibly because the anesthetist may inadvertently not follow the medial line when inserting the needle.

Hypertrophic scar pain, pruritus, and paresthesia symptoms are major and particular concerns for burn patients. However, because no effective and satisfactory methods exist for their alleviation, the clinical treatment for these symptoms is generally considered unsatisfactory. Therefore, their risk factors should be identified and prevented during management. We reviewed the medical records of 129 post-burn hypertrophy scar patients and divided them into two groups for each of three different symptoms based on the University of North Carolina "4P" Scar Scale: patients with scar pain requiring occasional or continuous pharmacological intervention (HSc pain, n=75) vs. patients without such scar pain (No HSc pain, n=54); patients with scar pruritus requiring occasional or continuous pharmacological intervention (HSc pruritus, n=63) vs. patients without such scar pruritus (No HSc pruritus, n=66); patients with scar paresthesia that influenced the patients' daily activities (HSc paresthesia, n=31) vs. patients without such scar paresthesia (No HSc paresthesia, n=98). Three multivariable logistic regression models were built, respectively, to identify the risk factors for hypertrophic burn scar pain, pruritus, and paresthesia development. Multivariable analysis showed that hypertrophic burn scar pain development requiring pharmacological intervention was associated with old age (odds ratio [OR]=1.046; 95% confidence interval [CI], 1.011-1.082, p=0.009), high body mass index(OR=1.242; 95%CI,1.068-1.445, p=0.005), 2-5-mm-thick post-burn hypertrophic scars (OR=3.997; 95%CI, 1.523-10.487; p=0.005), and 6-12-month post-burn hypertrophic scars (OR=4.686; 95%CI; 1.318-16.653; p=0.017). Hypertrophic burn scar pruritus development requiring pharmacological intervention was associated with smoking (OR=3.239; 95%CI, 1.380-7.603; p=0.007), having undergone surgical operation (OR=2.236; 95%CI, 1.001-4.998; p=0.049), and firm scars (OR=3.317; 95%CI, 1.237-8.894; p=0.017).

Although epidural anesthesia is considered safe, several complications may occur during puncture and insertion of a catheter. Incidences of paresthesia vary between 0.2 and 56%. A prospective, open, cohort-controlled pilot study was conducted in 188 patients, ASA I-III, age 19-87 years, scheduled for elective surgery and epidural anesthesia. We evaluated a 20 G polyamide (standard) catheter and a 20 G combined polyurethane-polyamide (new) catheter. Spontaneous reactions upon catheter-insertion, paresthesia on questioning, inadvertent dural or intravascular puncture, and reasons for early catheter removal were recorded. The incidence of paresthesia reported spontaneously was 21.3% with the standard catheter and 16.7% with the new catheter. Systematically asking for paresthesia almost doubled the paraesthesia rate. Intravascular cannulation occurred in 5%. No accidental dural punctures occurred. An overall incidence of 13.3% of technical problems led to early catheter removal. The new catheter was at least equivalent to the standard regarding epidural success rate and safety : rate of paresthesia, intravascular and dural cannulation.

Orthognathic surgery is the surgical procedure that makes correcting deformities of the bones in the region of the maxilla and mandible a reality in the Brazilian dentistry. However, this type of surgery usually involves paresthesia in the postoperative period, concerning the surgeons who perform them and generating discomfort to patients. This study aimed at evaluating the effect of infrared laser (830 nm) in the prevention and treatment of paresthesias after orthognathic surgery. Six patients underwent orthognathic surgery: the experimental group composed of 4 patients and the control group that did not receive laser therapy composed of 2 patients. The experimental group received laser applications during the transoperative and 12 postoperative sessions. Tests for mechanical (deep and shallow) and thermal (cold) sensitivity were performed in the preoperative and postoperative period (during 12 sessions) in the lip and chin areas by the same operator. The paresthesia was classified into 1, strong; 2, moderate; 3, mild; and 4, absent, through the patient's response to stimuli. The results showed that all patients had no disturbance of sensitivity in the preoperative period, but paresthesia was presented at various levels in the postoperative period. Both groups showed recovery of deep mechanical sensitivity within a shorter time interval compared with the superficial mechanical and thermal sensitivity. However, at the 12th assessment, patients who underwent the laser therapy showed better reduction in the level of paresthesia or even complete regression of this. The laser, therefore, brought benefits to the treatment of paresthesia, accelerating the return of neurosensorial sensitivity.

After an inferior alveolar nerve (IAN) injury, the onset of altered sensation usually begins immediately after surgery. However, it sometimes begins after several days, which is referred to as delayed paresthesia. The authors considered three different etiologies that likely produce inflammation along the nerve trunk and cause delayed paresthesia: compression of the clot, fibrous reorganization of the clot, and nerve trauma caused by bone fragments during clot organization. The aim of this article was to evaluate the etiology of IAN delayed paresthesia, analyze the literature, present a case series related to three different causes of this pathology, and compare delayed paresthesia with the classic immediate symptomatic paresthesia.

Traditional spinal cord stimulation (SCS) requires that paresthesia overlaps chronic painful areas. However, the new paradigm high-frequency SCS (HF-SCS) does not rely on paresthesia. A review of preclinical and clinical studies regarding the use of paresthesia-free HF-SCS for various chronic pain states. We reviewed available literatures on HF-SCS, including Nevro's paresthesia-free ultra high-frequency 10 kHz therapy (HF10-SCS). Data sources included relevant literature identified through searches of PubMed, MEDLINE/OVID, and SCOPUS, and manual searches of the bibliographies of known primary and review articles. The primary goal is to describe the present developing conceptions of preclinical mechanisms of HF-SCS and to review clinical efficacy on paresthesia-free HF10-SCS for various chronic pain states. HF10-SCS offers a novel pain reduction tool without paresthesia for failed back surgery syndrome and chronic axial back pain. Preclinical findings indicate that potential mechanisms of action for paresthesia-free HF-SCS differ from those of traditional SCS. To fully understand and utilize paresthesia-free HF-SCS, mechanistic study and translational research will be very important, with increasing collaboration between basic science and clinical communities to design better trials and optimize the therapy based on mechanistic findings from effective preclinical models and approaches. Future research in these vital areas may include preclinical and clinical components conducted in parallel to optimize the potential of this technology. © 2017 International Neuromodulation Society.

Paresthesia, a common feature of epidural spinal cord stimulation (SCS) for pain management, presents a challenge to the double-blind study design. Although sub-paresthesia SCS has been shown to be effective in alleviating pain, empirical criteria for sub-paresthesia SCS have not been established and its basic mechanisms of action at supraspinal levels are unknown. We tested our hypothesis that sub-paresthesia SCS attenuates behavioral signs of neuropathic pain in a rat model, and modulates pain-related theta (4-8 Hz) power of the electroencephalogram (EEG), a previously validated correlate of spontaneous pain in rodent models. Results show that sub-paresthesia SCS attenuates thermal hyperalgesia and power amplitude in the 3-4 Hz range, consistent with clinical data showing significant yet modest analgesic effects of sub-paresthesia SCS in humans. Therefore, we present evidence for anti-nociceptive effects of sub-paresthesia SCS in a rat model of neuropathic pain and further validate EEG theta power as a reliable 'biosignature' of spontaneous pain.

Multiple sclerosis (MS) is a chronic progressive autoimmune disease impacting both body and mind. Typically, patients with MS report fatigue, depression, and paresthesia. Standard treatment consists of immune modulatory medication, though there is growing evidence that exercising programs have a positive influence on fatigue and psychological symptoms such as depression. We tested the hypothesis that, in addition to the standard immune regulatory medication, either yoga or aquatic exercise can ameliorate both fatigue and depression, and we examined whether these interventions also influence paresthesia compared with a nonexercise control condition. Fifty-four women with MS (mean age: M = 33.94 yr, SD = 6.92) were randomly assigned to one of the following conditions: yoga, aquatic exercise, or nonexercise control. Their existing immune modulatory therapy remained unchanged. Participants completed questionnaires covering symptoms of fatigue, depression, and paresthesia, both at baseline and on completion of the study 8 wk later. Compared with the nonexercise control condition and over time, fatigue, depression, and paresthesia decreased significantly in the yoga and aquatic exercise groups. On study completion, the likelihood of reporting moderate to severe depression was 35-fold higher in the nonexercise control condition than in the intervention conditions (yoga and aquatic exercising values collapsed). The pattern of results suggests that for females with MS and treated with standard immune regulatory medication, exercise training programs such as yoga and aquatic exercising positively impact on core symptoms of MS, namely, fatigue, depression, and paresthesia. Exercise training programs should be considered in the future as possible complements to standard treatments.

This paper presents a probabilistic assessment of the risks of transient adult paresthesia (tingling of the extremities) resulting from ingestion of methylmercury (MeHg) in fish and shellfish. Two scenarios are evaluated: the baseline, in which the MeHg dose results from the combined effects of eating canned tuna fish, various marine seafood, and freshwater sportfish, and an impact scenario in which the Hg content of the freshwater sportfish is increased due to local deposition from a hypothetical 1000 Mw{sub e} coal-fired power plant. Measurements from the literature are used to establish the parameters of the baseline, including atmospheric rates of Hg deposition and the distributions of MeHg in fish. The Hg intake for the impact scenario is then based on linear scaling of the additional annual Hg deposition as estimated from a Guassian plume dispersion model. Human health responses are based on a logistic fit to the frequencies of paresthesia observed during a grain poisoning incident in Iraq 1971-2. Based on a background prevalence rate of 2.2% for adult paresthesia, the assessment predicts a 5% chance that the increase in paresthesia prevalence due to either baseline or incremental MeHg doses might approach about 1% of the background prevalence rate. 15 refs., 3 figs., 3 tabs.

Guillain-Barré syndrome is an acute demyelinating disease which presents in a classic form with muscular weakness and the lack of reflexes. There are multiple variations and atypical forms of the disease, being facial diplegia with paresthesia one of them. Also, the absence of reflexes in this syndrome is typical but not constant, since 10% of patients present reflexes. We describe a case of atypical presentation with bilateral facial palsy, paresthesia, brisk reflexes and weakness in the lower limbs in a 33 year old woman.

A case report is presented that deals with mental nerve paresthesia resulting from the "flare-up" of a mandibular second premolar with three root canals. A review of the literature and discussion follow, which suggest possible mechanisms that may be responsible for paresthesia as well as treatment regimens that may be used to minimize the incidence of this unexpected but occasional post-treatment endodontic sequela.

Background Continuous epidural anesthesia is useful for endoscopic urologic surgery, as mostly performed in the elderly patients. In such a case, it is necessary to obtain successful sacral anesthesia, and the insertion of epidural catheter in the caudad direction may be needed. However, continuous epidural catherization has been related to paresthesias. This study aimed to evaluate the effects of the direction of the catheter insertion on the incidence of paresthesias in the elderly patients. Methods Two hundred elderly patients scheduled for endoscopic urologic surgery were enrolled. The epidural catheter was inserted at L2-3, L3-4, and L4-5 using the Tuohy needle. In Group I (n = 100), the Tuohy needle with the bevel directed the cephalad during the catheter insertion. In Group II (n = 100), it directed the caudad. During the catheter insertion, an anesthesiologist evaluated the presence of paresthesias and the ease or difficulty during the catheter insertion. Results In Group I (n = 97), 15.5% of the patients had paresthesias versus 18.4% in Group II (n = 98), and there was no significant difference between the two groups. In paresthesia depending on the insertion site and the ease or difficulty during the catheter insertion, there were no significant differences between the two groups. Conclusions Our results concluded that the direction of epidural catheter insertion did not significantly influence the incidence of paresthesias in the elderly patients. PMID:23741568

Paresthesia is a well-known complication of extraction of mandibular third molars (MTMs). The authors evaluated the relationship between paresthesia after MTM extraction and the cortical integrity of the inferior alveolar canal (IAC) by using computed tomography (CT). The authors designed a retrospective cohort study involving participants considered, on the basis of panoramic imaging, to be at high risk of experiencing injury of the inferior alveolar nerve who subsequently underwent CT imaging and extraction of the MTMs. The primary predictor variable was the contact relationship between the IAC and the MTM as viewed on a CT image, classified into three groups: group 1, no contact; group 2, contact between the MTM and the intact IAC cortex; group 3, contact between the MTM and the interrupted IAC cortex. The secondary predictor variable was the number of CT image slices showing the cortical interruption around the MTM. The outcome variable was the presence or absence of postoperative paresthesia after MTM extraction. The study sample comprised 179 participants who underwent MTM extraction (a total of 259 MTMs). Their mean age was 23.6 years, and 85 (47.5 percent) were male. The overall prevalence of paresthesia was 4.2 percent (11 of 259 teeth). The prevalence of paresthesia in group 3 (involving an interrupted IAC cortex) was 11.8 percent (10 of 85 cases), while for group 2 (involving an intact IAC cortex) and group 1 (involving no contact) it was 1.0 percent (1 of 98 cases) and 0.0 percent (no cases), respectively. The frequency of nerve damage increased with the number of CT image slices showing loss of cortical integrity (P=.043). The results of this study indicate that loss of IAC cortical integrity is associated with an increased risk of experiencing paresthesia after MTM extraction.

Hydroxy-α-sanshool, the active ingredient in plants of the prickly ash plant family, induces robust tingling paresthesia by activating a subset of somatosensory neurons. However, the subtypes and physiological function of sanshool-sensitive neurons remain unknown. Here we use the ex vivo skin-nerve preparation to examine the pattern and intensity with which the sensory terminals of cutaneous neurons respond to hydroxy-α-sanshool. We found that sanshool excites virtually all D-hair afferents, a distinct subset of ultra-sensitive light touch receptors in the skin, and targets novel populations of Aβ and C-fiber nerve afferents. Thus, sanshool provides a novel pharmacological tool for discriminating functional subtypes of cutaneous mechanoreceptors. The identification of sanshool-sensitive fibers represents an essential first step in identifying the cellular and molecular mechanisms underlying tingling paresthesia that accompanies peripheral neuropathy and injury.

Eagle's syndrome is characterized by a variety of symptoms, including throat pain, sensation of a foreign body in the pharynx, dysphagia, referred otalgia, and neck and throat pain exacerbated by head rotation. Any styloid process longer than 25 mm should be considered elongated and will usually be responsible for Eagle's syndrome. Surgical resection of the elongated styloid is a routine treatment and can be accomplished using a transoral or an extraoral approach. We report a patient with a rare giant styloid process that was approximately 81.7 mm. He complained of a rare symptom: hemitongue paresthesia. After removal of the elongated styloid process using the extraoral approach, his symptoms, including the hemitongue paresthesia, were alleviated. We concluded that if the styloid process displays medium to severe elongation, the extraoral approach will be appropriate. Copyright © 2014 American Association of Oral and Maxillofacial Surgeons.

Loss of upper extremity motion caused by axillary burn scar contracture is a major complication of burn injury. Positioning acutely injured patients with axillary burns in positions above 90° of shoulder abduction may improve shoulder motion and minimize scar contracture. However, these positions may increase injury risk to the nerves of the brachial plexus. This study evaluated the occurrence of paresthesias, pain, and positional intolerance in four shoulder abduction positions in healthy adults. Sixty men and women were placed in four randomly assigned shoulder abduction positions for up to 2 hours: 1) 90° with elbow extension (90 ABD); 2) 130° with elbow flexion at 110° (130 ABD); 3) 150° with elbow extension (150 ABD); and 4) 170° with elbow extension (170 ABD). Outcome measures were assessed at baseline and every 30 minutes and included the occurrence of upper extremity paresthesias, position comfort/tolerance, and pain. Transient paresthesias, lasting less than 3 minutes, occurred in all test positions in 10 to 37% of the cases. Significantly fewer subjects reported paresthesias in the 90 ABD position compared with the other positions (P < .01). Pain was reported more frequently in the 170° position (68%) compared with the other positions (P < .01). Positioning with the elbow flexed or in terminal extension is not recommended, regardless of the degree of shoulder abduction. Positioning patients in a position of 150° of shoulder abduction was shown to be safe and well tolerated. Consideration of positions above this range should be undertaken cautiously and only with strict monitoring in alert and oriented patients for short time periods.

To identify volume and dose predictors of paresthesia after irradiation of the brachial plexus among women treated for breast cancer. The women had breast surgery with axillary dissection, followed by radiation therapy with (n=192) or without irradiation (n=509) of the supraclavicular lymph nodes (SCLNs). The breast area was treated to 50 Gy in 2.0-Gy fractions, and 192 of the women also had 46 to 50 Gy to the SCLNs. We delineated the brachial plexus on 3-dimensional dose-planning computerized tomography. Three to eight years after radiation therapy the women answered a questionnaire. Irradiated volumes and doses were calculated and related to the occurrence of paresthesia in the hand. After treatment with axillary dissection with radiation therapy to the SCLNs 20% of the women reported paresthesia, compared with 13% after axillary dissection without radiation therapy, resulting in a relative risk (RR) of 1.47 (95% confidence interval [CI] 1.02-2.11). Paresthesia was reported by 25% after radiation therapy to the SCLNs with a V40 Gy ≥ 13.5 cm(3), compared with 13% without radiation therapy, RR 1.83 (95% CI 1.13-2.95). Women having a maximum dose to the brachial plexus of ≥55.0 Gy had a 25% occurrence of paresthesia, with RR 1.86 (95% CI 0.68-5.07, not significant). Our results indicate that there is a correlation between larger irradiated volumes of the brachial plexus and an increased risk of reported paresthesia among women treated for breast cancer.

One prominent side effect from neurostimulation techniques, and in particular spinal cord stimulation (SCS), is the change in intensity of stimulation when moving from an upright (vertical) to a recumbent or supine (horizontal) position and vice versa. It is well understood that the effects of gravity combined with highly conductive cerebrospinal fluid provide the mechanism by which changes in body position can alter the intensity of stimulation-induced paresthesias. While these effects are well established for leads that are placed within the more medial aspects of the spinal canal, little is known about these potential effects in leads placed in the lateral epidural space and in particular within the neural foramina near the dorsal root ganglion (DRG). We prospectively validated a newly developed paresthesia intensity rating scale and compared perceived paresthesia intensities when subjects assumed upright vs. supine bodily positions during neuromodulation of the DRG. On average, the correlation coefficient between stimulation intensity (pulse amplitude) and perceived paresthesia intensity was 0.83, demonstrating a strong linear relationship. No significant differences in paresthesia intensities were reported within subjects when moving from an upright (4.5 ± 0.14) to supine position 4.5 (± 0.12) (p > 0.05). This effect persisted through 12 months following implant. Neuromodulation of the DRG produces paresthesias that remain consistent across body positions, suggesting that this paradigm may be less susceptible to positional effects than dorsal column stimulation. © 2014 International Neuromodulation Society.

Bilateral sagittal split osteotomy (BSSO) aims to correct congenital or acquired mandibular abnormities. Temporary or permanent neurosensory disturbance is the most frequent complication of BSSO. To evaluate the influence of IAN handling during osteotomy, the authors undertook a prospective study in 290 patients who underwent BSSO. The occurrence and duration of paresthesia was evaluated 4 weeks, 3 months, 6 months, and 1 year after surgery. Paresthesia developed immediately after surgery in almost half of the patients. Most cases of paresthesia resolved within 1 year after surgery. A significantly higher prevalence of paresthesia was observed on the left side. The authors found a correlation between the type of IAN position between the left and right side. The type of split (and IAN exposure) did not have a significant effect on the occurrence or duration of neurosensory disturbance of the IAN. The authors did not find a correlation between the occurrence and duration of paresthesia and the direction of BSSO. Mandibular hypoplasia or mandibular progenia did not represent a predisposition for the development of paresthesia. In the development of IAN paresthesia, the type of IAN exposure and the split is less important than the side on which the split is carried out.

Paresthesia is a rare clinical finding subsequent to surgery accompanied by the administration of local anesthetics. A small patient population was identified whose clinical problem may be explained by neurotoxicity due to a local anesthetic metabolite. Reasonable questions arise from these clinical observations that would benefit from prospective studies to explain sensory loss on a biochemical basis. PMID:2077986

High-Frequency Stimulation of Dorsal Column Axons: Potential Underlying Mechanism of Paresthesia-Free Neuropathic Pain Relief.

Science.gov (United States)

Arle, Jeffrey E; Mei, Longzhi; Carlson, Kristen W; Shils, Jay L

2016-06-01

Spinal cord stimulation (SCS) treats neuropathic pain through retrograde stimulation of dorsal column axons and their inhibitory effects on wide dynamic range (WDR) neurons. Typical SCS uses frequencies from 50-100 Hz. Newer stimulation paradigms use high-frequency stimulation (HFS) up to 10 kHz and produce pain relief but without paresthesia. Our hypothesis is that HFS preferentially blocks larger diameter axons (12-15 µm) based on dynamics of ion channel gates and the electric potential gradient seen along the axon, resulting in inhibition of WDR cells without paresthesia. We input field potential values from a finite element model of SCS into an active axon model with ion channel subcomponents for fiber diameters 1-20 µm and simulated dynamics on a 0.001 msec time scale. Assuming some degree of wave rectification seen at the axon, action potential (AP) blockade occurs as hypothesized, preferentially in larger over smaller diameters with blockade in most medium and large diameters occurring between 4.5 and 10 kHz. Simulations show both ion channel gate and virtual anode dynamics are necessary. At clinical HFS frequencies and pulse widths, HFS preferentially blocks larger-diameter fibers and concomitantly recruits medium and smaller fibers. These effects are a result of interaction between ion gate dynamics and the "activating function" (AF) deriving from current distribution over the axon. The larger fibers that cause paresthesia in low-frequency simulation are blocked, while medium and smaller fibers are recruited, leading to paresthesia-free neuropathic pain relief by inhibiting WDR cells. © 2016 International Neuromodulation Society.

Effect of Cryoanalgesia on Post Midsternotomy Pain and Paresthesia Following CABG

Directory of Open Access Journals (Sweden)

H Hosseini

2009-07-01

Full Text Available Introduction: Control of post thoracotomy pain is particularly important in prevention of post operative respiratory complications. Several methods are proposed for control of postoperative pain. Cryoanalgesia by freezing of intercostal nerves is able to providing long term pain relief in post operative period which probably results in cutaneous sensory changes. Methods: This clinical trial study was done on 124 patients who underwent CABG surgery. Patients were randomly divided in two groups; control group (group I and study group (group II. In study group cryoanalgesia was applied intraoperatively on the intercostal nerves. All of the patients received appropriate analgesia on demand in postoperative period. Pain in LIMA harvesting site and sternum was measured by visual analogue pain score before discharge, one and three months following cryoanalgesia. In all of the patient’s, presence of paresthesia was evaluated. The amount of administered analgesics (narcotic, opium, indomethacin was noted daily. Data of this investigation was analyzed and evaluated using SPSS 11.5 software. Results: Pain score of sternum was higher in study group before discharge and was lower at one and three months after operation than the control group that was statistically significant (P=0.01. Pain score of LIMA region before discharge was higher, at one month post operation was equal and at three months post operative was lower than the control group (P=0.045. Use of morphine and opium was lower (P=0.017 and use of indomethacin was higher in the cryoanalgesia group that was statistically significant (P=0.001. Incidence of paresthesia was lower in the study group (P=0.001. Conclusion: It is proposed that cryoanalgesia is a safe and effective method for reduction of pain and paresthesia and need for analgesics following CABG operation.

β-alanine is a common ingredient in supplements consumed by athletes. Indeed, athletes may believe that the β-alanine induced paresthesia, experienced shortly after ingestion, is associated with its ergogenic effect despite no scientific mechanism supporting this notion. The present study examined changes in cycling performance under conditions of β-alanine induced paresthesia. Eight competitive cyclists (VO2max = 61.8 ± 4.2 mL·kg·min(-1)) performed three practices, one baseline and four experimental trials. The experimental trials comprised a 1-km cycling time trial under four conditions with varying information (i.e., athlete informed β-alanine or placebo) and supplement content (athlete received β-alanine or placebo) delivered to the cyclist: informed β-alanine/received β-alanine, informed placebo/received β-alanine, informed β-alanine/received placebo and informed placebo/received placebo. Questionnaires were undertaken exploring the cyclists' experience of the effects of the experimental conditions. A possibly likely increase in mean power was associated with conditions in which β-alanine was administered (±95% CL: 2.2% ± 4.0%), but these results were inconclusive for performance enhancement (p = 0.32, effect size = 0.18, smallest worthwhile change = 56% beneficial). A possibly harmful effect was observed when cyclists were correctly informed that they had ingested a placebo (-1.0% ± 1.9%). Questionnaire data suggested that β-alanine ingestion resulted in evident sensory side effects and six cyclists reported placebo effects. Acute ingestion of β-alanine is not associated with improved 1-km TT performance in competitive cyclists. These findings are in contrast to the athlete's "belief" as cyclists reported improved energy and the ability to sustain a higher power output under conditions of β-alanine induced paresthesia.

Paresthesia was the third-most-common adverse event following immunization (AEFI) with 2009 monovalent AS03-adjuvanted A(H1N1)pdm09 vaccine in Quebec, Canada and was also frequently reported in Europe. This study assessed clinical features and risk factors associated with this unexpected AEFI. Reports to the passive surveillance system were summarized. A case-control study was conducted to assess risk factors and additional investigations were undertaken among cases with symptoms persisting ≥12 months. There were 328 reports of paresthesia affecting the vaccinated arm (58%), but also face (45%), lower limbs (40%) and back/thorax (23%) with numbness but also muscle weakness (61%), motor impairment (61%), generalized myalgia (37%), visual (14%) and/or speech effects (15%). Reporting rate was highest in women of reproductive age, peaking at 30-39 years-old (28/100,000 doses administered) and exceeding that of men of the same age (7/100,000 doses) by 4-fold. Median time to onset was 2h. Symptoms subsided within one week in 37% but lasted ≥6 months in 26%. No consistent or objective neurological findings were identified. Risk was increased with allergy history, respiratory illness the day of vaccination, depressive symptoms and family history of pulmonary disease, but decreased with physical activity the day of vaccination, and regular weekly alcohol consumption. Paresthesia following 2009 pandemic vaccine receipt lasted several weeks and included other motor-sensory disturbances in an important subset of patients. Although it does not correspond with known neurological disease, and causality remains uncertain, further investigation is warranted to understand the nature and frequency of paresthesia as a possible AEFI with influenza vaccines.

Spinal cord stimulation (SCS) traditionally is thought to require paresthesia, but there is evidence that paresthesia-free stimulation using high-density (HD) parameters might also be effective. The purpose of this study is to evaluate relative effectiveness of conventional, subthreshold HD, and sham stimulation on pain intensity and quality of life. Fifteen patients with response to conventional stimulation (60 Hz/350 μsec) were screened with a one-week trial of subthreshold HD (1200 Hz/200 μsec/amplitude 90% paresthesia threshold) and enrolled if there was at least 50% reduction on visual analog scale (VAS) for pain. Subjects were randomized into two groups and treated with four two-week periods of conventional, subthreshold HD, and sham stimulation in a randomized crossover design. Four of 15 patients responded to subthreshold HD stimulation. Mean VAS during conventional, subthreshold HD, and sham stimulation was 5.32 ± 0.63, 2.29 ± 0.41, and 6.31 ± 1.22, respectively. There was a significant difference in pain scores during the blinded crossover study of subthreshold HD vs. sham stimulation (p Paresthesia are not necessary for pain relief using commercially available SCS devices, and may actually increase attention to pain. Subthreshold HD SCS represents a viable alternative to conventional stimulation among patients who are confirmed to have a clinical response to it. © 2015 International Neuromodulation Society.

Full Text Available Objectives : Hand paresthesia is common syndrome and the cause is more unknown than known reason. The Purpose of this study were investigated the effects of Myofacial Pain Syndrome theory to make diagnosis and treatment by Pharmacopuncture for the patients of hand paresthesia. Method : This study was carried out to established the clinical criteria of hand parethesia. The patients who had past history of diabeics, neuropathy induced by alcohol or drug were excluded, and 86 patients who had hand paresthesia related with unknown-reason was selected by the interview process. And the effects of Pharmacopuncture theory were analyzed using VAS score before and after treatment. Results and conclusions : 56.9% of unknown-reason patients are positive at diagnosis by MPS theory. While positive group decrease from 62.81±14.27 to 25.28±15.97, negative group decrease from 55.88±10.92 to 48.28±14.01 by VAS scores. Positive group was accordingly more effective than negative group. So diagnosis and treatment for hand numbness patients by MPS theory was useful in clinical.

A paucity of appreciation exists that the "double crush" phenomenon can account for persistent leg symptoms even after spinal neural decompression surgery. We present an unusual case of multiple locations of nerve compression causing persistent lower limb paresthesia in a 40-year old male patient. The patient's lower limb paresthesia was persistent after an initial spinal surgery to treat spinal lateral recess stenosis thought to be responsible for the symptoms. It was later discovered that he had peroneal muscle herniations that had caused superficial peroneal nerve entrapments at 2 separate locations. The patient obtained much symptomatic relief after decompression of the peripheral nerve. The "double crush" phenomenon and multiple levels of nerve compression should be considered when evaluating lower limb neurogenic symptoms, especially after spinal nerve root surgery.

A single-center retrospective study. To compare the speed of recovery of different sensory symptoms, pain, numbness, and paresthesia, after lumbar nerve root decompression. Lumbar radiculopathy is characterized by different sensory symptoms like pain, numbness, and paresthesia, which may resolve at different rates after surgical decompression. Eighty-five cases with predominant lumbar radiculopathy treated surgically were reviewed. Oswestry Disability Index score, 36-Item Short Form Health Survey scores (Physical Component Summary and Mental Component Summary), and pain drawing at preoperative and at 6 weeks, 3 months, 6 months, and 1-year follow-up were reviewed. Recovery rate between different sensory symptoms were compared in all patients, and between the short-term compression (paresthesia; 28 (32.9%) had all these 3 component of sensory symptoms. Mean pain score improved fastest (55.3% at 6 wk); further resolution until 1 year was slow and not significant compared with each previous visit. Both numbness and paresthesia scores showed a trend of faster recovery during the initial 6-week period (20.5% and 24%, respectively); paresthesia recovery reached a plateau at 3 months postoperatively, but numbness continued a slow recovery until 1-year follow-up. Both Oswestry Disability Index score and Physical Component Summary scores (54.02 ± 1.87 and 26.29 ± 0.93, respectively, at baseline) improved significantly compared with each previous visits at 6 weeks and 3 months postoperatively, but further improvement was insignificant. Mental Component Summary showed a similar trend but smaller improvement. The short-term compression group had faster recovery of pain than the long-term compression group. In lumbar radiculopathy patients after surgical decompression, pain recovers fastest, in the first 6 weeks postoperatively, followed by paresthesia recovery that plateaus at 3 months postoperatively. Numbness recovers at a slower pace but continues until 1 year. 4.

Home Use of a Pyrethroid-Containing Pesticide and Facial Paresthesia in a Toddler: A Case Report

Full Text Available Paresthesias have previously been reported among adults in occupational and non-occupational settings after dermal contact with pyrethroid insecticides. In this report, we describe a preverbal 13-month-old who presented to his primary care pediatrician with approximately 1 week of odd facial movements consistent with facial paresthesias. The symptoms coincided with a period of repeat indoor spraying at his home with a commercially available insecticide containing two active ingredients in the pyrethroid class. Consultation by the Northwest Pediatric Environmental Health Specialty Unit and follow-up by the Washington State Department of Health included urinary pyrethroid metabolite measurements during and after the symptomatic period, counseling on home clean up and use of safer pest control methods. The child’s symptoms resolved soon after home cleanup. A diagnosis of pesticide-related illness due to pyrethroid exposure was made based on the opportunity for significant exposure (multiple applications in areas where the child spent time, supportive biomonitoring data, and the consistency and temporality of symptom findings (paresthesias. This case underscores the vulnerability of children to uptake pesticides, the role of the primary care provider in ascertaining an exposure history to recognize symptomatic illness, and the need for collaborative medical and public health efforts to reduce significant exposures in children.

The aims of the present study were to analyze the effectiveness of current perception threshold (CPT) testing to determine patients' minor paresthesia of the infraorbital region after open reduction and internal fixation (ORIF) for unilateral zygomaticomaxillary bone fracture (UZF) and to clarify which nerve fiber was related to the paresthesia. We conducted a retrospective cohort study of patients who had undergone ORIF after UZF. We also performed neurosensory testing for healthy volunteers who served as the control group. The predictor variables were the period of measurement of Semmes-Weinstein monofilament (S-W) testing and CPT testing (preoperatively and 1 and 5 years postoperatively), measurement side, and disease status (UZF or control). The outcome variables were paresthesia status of the infraorbital nerve region and the results of S-W and CPT testing in both UZF and control groups. The differences in the S-W and CPT values between the affected and unaffected sides in the UZF group and between the UZF and control groups were analyzed by t test (P paresthesia at 1 and 5 years postoperatively. At 5 years postoperatively, the S-W values in all patients showed normalization. From the results of CPT testing, only the A-β fiber function showed significant improvement at 5 years postoperatively. The CPT test was an effective sensory test for determining minor paresthesia that could not be detected using S-W testing. Paresthesia of the infraorbital nerve region was caused by the damaged A-δ and C fibers. Copyright © 2015 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc.

The purpose of this study was to compare findings on the relationship between impacted molar roots and the mandibular canal in panoramic and three-dimensional cone-beam CT (CBCT) images to identify those that indicated risk of postoperative paresthesia. The relationship between impacted molars and the mandibular canal was first classified using panoramic images. Only patients in whom the molar roots were either in contact with or superimposed on the canal were evaluated using CBCT. Of 466 patients examined using both panoramic and CBCT images, 280 underwent surgical extraction of an impacted molar, and 15 of these (5%) reported postoperative paresthesia. The spatial relationship between the impacted third molar root and the mandibular canal was determined by examining para-sagittal sections (lingual, buccal, inter-radicular, inferior, and combinations) obtained from the canal to the molar root and establishing the proximity of the canal to the molar root (in contact with or without loss of the cortical border and separate). The results revealed that darkening of the roots with interruption of the mandibular canal on panoramic radiographs and the inter-radicular position of the canal in CBCT images were characteristic findings indicative of risk of postoperative paresthesia. These results suggest that careful surgical intervention is required in patients with the above characteristics.

Evidence is mounting that magnet therapy could alleviate the symptoms of multiple sclerosis (MS). This study was performed to test the effects of the pulsing magnetic fields on the paresthesia in MS patients. This study has been conducted as a randomized, double-blind, parallel-group clinical trial during the April 2012 to October 2013. The subjects were selected among patients referred to MS clinic of Imam Reza Hospital; affiliated to Kermanshah University of Medical Sciences, Iran. Sixty three patients with MS were included in the study and randomly were divided into two groups, 35 patients were exposed to a magnetic pulsing field of 4mT intensity and 15-Hz frequency sinusoidal wave for 20min per session 2 times per week over a period of 2 months involving 16 sessions and 28 patients was exposed to a magnetically inactive field (placebo) for 20min per session 2 times per week over a period of 2 months involving 16 sessions. The severity of paresthesia was measured by the numerical rating scale (NRS) at 30, 60days. The study primary end point was NRS change between baseline and 60days. The secondary outcome was NRS change between baseline and 30days. Patients exposing to magnetic field showed significant paresthesia improvement compared with the group of patients exposing to placebo. According to our results pulsed magnetic therapy could alleviate paresthesia in MS patients .But trials with more patients and longer duration are mandatory to describe long-term effects.

Transient neurologic dysfunction is a characteristic feature of migraine. About 20% of migraineurs may experience various symptoms in the absence of any headache at one time or another. Visual auras are the most common auras of migraine, and migraine is considered as the most common cause of transient vision loss in young patients. Sensory auras are the second most common migrainous auras. However, the literature is silent for isolated sensory aura as a migraine equivalent. Herein we report 14 patients with recurrent episodic paresthesia in the limbs and other body parts. All patients fulfilled the diagnostic criteria of "typical aura without headache" of ICHD-3β. All patients were subjected to various investigations to rule out secondary causes. Ten patients received antimigraine drugs and all showed a positive response to therapy. Recurrent spontaneous paresthesia is quite common in the general population and many patients remain undiagnosed. We speculate that a subset of patients might be related to migrainous sensory auras. © 2015 American Headache Society.

Chronic post-sternotomy chest pain and paresthesia (PCPP) are frequently seen and reduce the quality of life. We aimed to demonstrate the efficacy and safety of gabapentin compared with diclofenac in the treatment of PCPP and to elucidate the similarities of PCPP to neuropathic pain syndromes. The prospective, randomized, open-label, blinded end-point design of study was used. One hundred and ten patients having PCPP lasting three months or more were randomized to receive 800 mg/daily gabapentin (n=55) and 75 mg/daily diclofenac (n=55) for thirty days. All patients have undergone cardiac surgery and median sternotomy. The perception of pain or paresthesia was evaluated as 0--Normal (no pain or paresthesia), 1--Mild, 2--Moderate, 3--Severe at baseline and after thirty days of treatment. Recurrences were questioned after three months. Statistical analyses were performed using independent samples t, Chi-square, continuity correction, Fisher's exact, Mann Whitney U and Kruskal Wallis tests. In gabapentin group, mean pain and paresthesia scores regressed from 2.12+/- 0.76 to 0.54+/- 0.83 (pparesthesia scores regressed in diclofenac group from 1.93+/- 0.8 to 1.0+/- 1.13 (p<0.001) and from 1.76+/- 0.74 to 1.24+/- 0.96 (p=0.002), respectively. Although, both gabapentin and diclofenac were found to be effective without obvious side effects in the treatment of PCPP (p<0.001), gabapentin was found to be superior to diclofenac (p=0.001 and p<0.001, respectively). Adverse effects were seen in 7% of patients on gabapentin and 4% of patients on diclofenac. Results also showed that symptomatic relief with gabapentin lasts longer than diclofenac (p<0.001). Both gabapentin and diclofenac are effective in the treatment of chronic PCPP, without obvious side effects. However, gabapentin is found to be superior to diclofenac and its effects sustain longer. The results show that there may be some evidence in PCPP as a kind of neuropathic pain.

In spinal cord stimulation for the management of chronic, intractable pain, a satisfactory analgesic effect can be obtained only when the stimulation-induced paresthesias cover all painful body areas completely or partially. To investigate the effect of stimulus pulse width (PW) and contact configuration (CC) on the area of paresthesia (PA), perception threshold (VPT), discomfort threshold (VDT), and usage range (UR) in spinal cord stimulation. Chronic pain patients were tested during a follow-up visit. They were stimulated monopolarly and with the CC giving each patient the best analgesia. VPT, VDT, and UR were determined for PWs of 90, 210, and 450 microseconds. The paresthesia contours at VDT were drawn on a body map and digitized; PA was calculated; and its anatomic composition was described. The effects of PW and CC on PA, VPT, VDT, and UR were tested statistically. Twenty-four of 31 tests with low thoracic stimulation and 8 of 9 tests with cervical stimulation gave a significant extension of PA at increasing PW. In 14 of 18 tests (low thoracic), a caudal extension was obtained (primarily in L5-S2). In cervical stimulation the extension was predominantly caudal as well. In contrast to VPT and VDT, UR is not significantly different when stimulating with any CC. PA extends caudally with increasing PW. The mechanism includes that the larger and smaller dorsal column fibers have a different mediolateral distribution and that smaller dorsal column fibers have a smaller UR and can be activated only when PW is sufficiently large. A similar effect of CC on PA is unlikely as long as electrodes with a large intercontact distance are applied.

BACKGROUND A rare variant of Guillain-Barré syndrome (GBS) consists of facial diplegia and paresthesia, but an even more rare association is with facial hemiplegia, similar to Bell's palsy. This case report is of this rare variant of GBS that was associated with IgG antibodies to galactocerebroside and phosphatidic acid. CASE REPORT A 54-year-old man presented with lower left facial palsy and paresthesia of his extremities, following an upper respiratory tract infection. Physical examination confirmed lower left facial palsy and paresthesia of his extremities with hyporeflexia of his lower limbs and sensory loss of all four extremities. The differential diagnosis was between a variant of GBS and Bell's palsy. Following initial treatment with glucocorticoids followed by intravenous immunoglobulin (IVIG), his sensory abnormalities resolved. Serum IgG antibodies to galactocerebroside and phosphatidic acid were positive in this patient, but not other antibodies to glycolipids or phospholipids were found. Five months following discharge from hospital, his left facial palsy had improved. CONCLUSIONS A case of a rare variant of GBS is presented with facial diplegia and paresthesia and with unilateral facial palsy. This rare variant of GBS may which may mimic Bell's palsy. In this case, IgG antibodies to galactocerebroside and phosphatidic acid were detected.

Spontaneous paresthesia of the mental nerve is considered an ominous clinical sign. Mental nerve paresthesia has also been referred to as numb chin syndrome. Several potentially different factors have been investigated for their role in interfering with the inferior alveolar nerve (IAN) and causing mental nerve neuropathy. In the present case, the patient had an elongated calcified styloid process that we hypothesized had caused IAN irritation during mandibular movement. This eventually resulted in progressive loss of sensation in the mental nerve region. To our knowledge, this dynamic irritation, with complete recovery after resection of the styloid process, has not been previously reported.

Transforaminal and interlaminar epidural steroid injections are commonly used interventional pain management procedures in the treatment of radicular low back pain. Even though several studies have shown that transforaminal injections provide enhanced short-term outcomes in patients with radicular and low back pain, they have also been associated with a higher incidence of unintentional intravascular injection and often dire consequences than have interlaminar injections. We compared 2 different approaches, midline and lateral parasagittal, of lumbar interlaminar epidural steroid injection (LESI) in patients with unilateral lumbosacral radiculopathic pain. We also tested the role of concordant pressure paresthesia occurring during LESI as a prognostic factor in determining the efficacy of LESI. Prospective, randomized, blinded study. Pain management center, part of a teaching-community hospital in a major metropolitan US city. After Institutional Review Board approval, 106 patients undergoing LESI for radicular low back pain were randomly assigned to one of 2 groups (53 patients each) based on approach: midline interlaminar (MIL) and lateral parasagittal interlaminar (PIL). Patients were asked to grade any pressure paresthesia as occurring ipsilaterally or contralaterally to their "usual and customary pain," or in a distribution atypical of their daily pain. Other variables such as: the Oswestry Disability Index questionnaire, pain scores at rest and during movement, use of pain medications, etc. were recorded 20 minutes before the procedure, and on days 1, 7, 14, 21, 28, 60, 120, 180 and 365 after the injection. Results of this study showed statistically and clinically significant pain relief in patients undergoing LESI by both the MIL and PIL approaches. Patients receiving LESI using the lateral parasagittal approach had statistically and clinically longer pain relief then patients receiving LESI via a midline approach. They also had slightly better quality of

Full Text Available Paresthesiae-producing deep brain stimulation (stimulation of ventrocaudal nucleus - VC, medial lemniscus - ML or internal capsule - IC is one of the few procedures to treat the steady element of neural injury pain (NIP currently available. Reviewing the first 60 patients with NIP submitted to deep brain stimulation (DBS from 1978 to 1991 at the Division of Neurosurgery, Toronto Hospital, University of Toronto, we observed that 6 patients complained of unpleasant paresthesiae with paresthesiae-producing DBS, preventing permanent electrode implantation in all of them. Such patients accounted for 15% of the failures (6 out of 40 failures in our series. In an attempt to improve patient selection, we reviewed our patients considering a number of parameters in order to determine risk factors for unpleasant paresthesiae elicited by paresthesiae-producing DBS. The results showed that this response happenned only in patients with brain central pain complaining of evoked pain, secondary to a supratentorial lesion. Age, sex, duration of pain, quality of the steady pain, size of the causative lesion and site (VC,ML,IC and type (micro or macroelectrode of surgical exploration were not important factors. Unpleasant paresthesiae in response to dorsal column stimulation, restricted thalamic lesion on computed tomography and the occurrence of associated intermittent pain were considered major risk factors in this subset of patients and the presence of cold allodynia or hyperpathia in isolation and the absence of sensory loss were considered minor risk factors. It is our hope that the criteria here established will improve patient selection and so, the overall results of DBS.A estimulação cerebral profunda (ECP de sítios cuja estimulação elicita parestesia (núcleo talâmico ventrocaudal - VC, lemnisco medial - LM e cápsula interna - CI é um dos poucos métodos atualmente disponíveis para o tratamento do elemento constante da dor por injúria neural (DIN

The aim of our study was to evaluate the extent to which the preservation or the section of the intercostobrachial nerve (ICBN) influences the development of postoperatoryparesthesia and to assess whether the development of paresthesiamay change the patient's life quality after surgical treatment for breast carcinoma. We performed a nonrandomized retrospective study including 100 patients who underwent axillary lymph node dissection for infiltrating breast carcinoma associated with axillary lymph node metastases. Using a questionnaire we studied the patients general life quality in the postoperative period. For the statistical analysis we used GraphPad Prism, Fisher'™s exact test and Chi square test. Results: 100 patients were included in our study with a mean age of 59.7 years. In 50 cases, the ICBN was preserved (Group 1),while in the remaining 50 cases the ICBN was sectioned during surgery (Group 2). Significantly more patients from Group 2 complained about postoperative paresthesia (p=0.026). In our series, the management of the ICBN cannot be significantly correlated with the impairment of the patients daily activities (p=0.2), sleeping cycle (p=0.2), and general life quality after surgery (p=0.67). We can conclude that the management of ICBN has a great influence on the development of postoperative paresthesia. Although the paresthesia does not have a negative effect on the patient'™s life quality in the postoperative period, in our opinion it is important to preserve the ICBN in order to prevent postoperative paresthesia.

To search major Islamic Traditional Medicine (ITM) textbooks for definition, etiology and medicinal plants used to manage 'khadar' or 'paresthesia', a common sensory symptom of multiple sclerosis (MS) and peripheral neuropathies. In addition, the conformity of the efficacy of ITM-suggested plants with the findings from modern pharmacological research on MS will be discussed. Data on the medicinal plants used to treat 'khadar' were obtained from major ITM texts. A detailed search in PubMed, ScienceDirect, Scopus and Google Scholar databases was performed to confirm the effects of ITM-mentioned medicinal plants on MS in view of identified pharmacological actions. Moringa oleifera Lam., Aloe vera (L.) Burm.f., Euphorbia species, Citrullus colocynthis (L.) Schrad., and Costus speciosus (Koen ex. Retz) Sm. are among the most effective ITM plants for the management of 'khadar'. Recent experimental evidence confirms the effectiveness of the mentioned plants in ameliorating MS symptoms. Moreover, according to ITM, prolonged exposure to cold and consuming foodstuff with cold temperament might be involved in the etiopathogenesis of MS. The use of traditional knowledge can help finding neglected risk factors as well as effective and safe therapeutic approaches, phytomedicines and dietary habits for the management of paresthesia and related disorders such as MS.

To compare the therapeutic effects on upper extremity paresthesia of intra-muscular steroid injections into the scalene muscle with those of stretching exercise only. Twenty patients with upper extremity paresthesia who met the criteria were recruited to participate in this single-blind, crossover study. Fourteen of 20 patients were female. The average age was 45.0 ± 10.5 years and duration of symptom was 12.2 ± 8.7 months. Each participant completed one injection and daily exercise program for 2 weeks. After randomization, half of all patients received ultrasound-guided injection of scalene muscles before exercise, while the other was invested for the other patients. After two weeks, there was a significant decrease of the visual analog scale score of treatment effect compared with baseline in both groups (6.90 to 2.85 after injection and 5.65 to 4.05 after stretching exercise, p50% reduction in post-treatment visual analog scale, was 18 of 20 (90.0%) after injection, compared to 5 of 20 (25.0%) after stretching exercise. There were no cases of unintended brachial plexus block after injection. Ultrasound-guided steroid injection or stretching exercise of scalene muscles led to reduced upper extremity paresthesia in patients who present with localized tenderness in the scalene muscle without electrodiagnostic test abnormalities, although injection treatment resulted in more improvements. The results suggest that symptoms relief might result from injection into the muscle alone not related to blockade of the brachial plexus.

Pain relief via spinal cord stimulation (SCS) has historically revolved around producing paresthesia to replace pain, with success measured by the extent of paresthesia-pain overlap. In a recent murine study, by Shechter et al., showed the superior efficacy of high frequency SCS (1 kHz and 10 kHz) at inhibiting the effects of mechanical hypersensitivity compared to sham or 50 Hz stimulation. In the same study, authors report there were no differences in efficacy between 1 kHz and 10 kHz delivered at subperception stimulation strength (80% of motor threshold). Therefore, we designed a randomized, 2 × 2 crossover study of low frequency supra-perception SCS vs. subperception SCS at 1 kHz frequency in order to test whether subperception stimulation at 1 kHz was sufficient to provide effective pain relief in human subjects. Twenty-two subjects with SCS, and inadequate pain relief based on numeric pain rating scale (NPRS) scores (>5) were enrolled, and observed for total of seven weeks (three weeks of treatment, one week wash off, and another three weeks of treatment). Subjects were asked to rate their pain on NPRS as a primary efficacy variable, and complete the Oswestry Disability Index (ODI) and Patient's Global Impression of Change (PGIC) as secondary outcome measures. Out of 22 subjects that completed the study, 21 subjects (95%) reported improvements in average, best, and worst pain NPRS scores. All NPRS scores were significantly lower with subperception stimulation compared to paresthesia-based stimulation (p paresthesia based stimulation on ODI scores (p = 3.9737 × 10 -5 ) and PGIC scores (p = 3.0396 × 10 -5 ). © 2016 International Neuromodulation Society.

Full Text Available Objectives: The objective of this study was to compare the effects of Sweet Bee Venom(Sweet BV Therapy between the hand paresthesia patients with Osteoporosis and without Osteoporosis. Methods: This study was carried out to established the clinical criteria of hand parethesia. The patients who had past history of diabeics, neuropathy induced by alcohol or drug and was positive on Myofacial Pain Syndrome Theory were excluded. 32 patients who had hand paresthesia related with unknown-reason was selected by the interview process. And the effects of treatment were analyzed using VAS score before treatment, after treatment, after 1 month and after 3 months. Results and conclusion: After treatment, While Osteoporosis group decrease from 64.81±17.81 to 27.21±17.32, Non-Osteoporosis group decrease from 58.76±11.43 to 24.74±13.81 by VAS scores. and After 3 months, While Osteoporosis group increase from 27.21±17.32 to 54.96±19.40, Non-Osteoporosis group increase from 24.74±13.81 to 32.43±15.57. Non-Osteoporosis group was accordingly more effective than Osteoporosis group after 3 months. So Sweet BV therapy for hand numbness patients without Osteoporosis was effective than patients with Osteoporosis.

Identification of early presenting signs of the Basal Cell Nevus (BCNS; synonyme Gorlin-Goltz) syndrome, which is associated with a principal triad of multiple basal cell nevi, jaw odontogenic keratocysts, and skeletal anomalies, in stomatological and neurological practices. Proposal of multidisciplinary diagnostic algorithm comprising other medical specialists, including pathology, imaging, laboratory and molecular analyses based on the study outcomes. Case report of a male patient reporting paresthesia of their lower jaw, with right facial asymmetry (maxilla and mandible) and radiological detection of large osteolytic lesions in both jaws, including a retrospective analysis of a representative Czech cohort with BCNS from within the last decade. Clinical, imaging and laboratory analyses were carried out at a national tertiary centre. A multidisciplinary clinical approach followed by surgical management lead to the identification of odontogenic cysts, which were substantiated by histological examination. DNA sequencing of the PTCH1 gene detected a c.2929dupT resulting in p. Tyr977Leufs*16 pathogenic variant. This finding confirmed the clinical and laboraoty diagnosis of BCNS. Parental DNA analysis showed that this causal genetic defect arose de novo. Surgical management and orthodontic therapy were successful. Analysis of the reported case and retrospective data analysis provided evidence that paresthesia of the lower jaw should be considered as one of the early presenting signs of this rare disorder in stomatological and neurological practice. Obtained results allowed us to formulate recommendations for diagnostic practice in stomatology and neurology.

The aim of this retrospective study was to evaluate the effectiveness of laser therapy for acceleration and recovery of nerve sensitivity after orthognathic or minor oral surgeries, by analysis of clinical records of patients treated at the Special Laboratory of Lasers in Dentistry (LELO, School of Dentistry, University of São Paulo), throughout the period 2007-2013. Nerve tissue lesions may occur during various dental and routine surgical procedures, resulting in paresthesia. Laser therapy has been shown to be able to accelerate and enhance the regeneration of the affected nerve tissue; however, there are few studies in the literature that evaluate the effects of treatment with low-power laser on neural changes after orthognathic or minor oral surgeries. A total of 125 clinical records were included, and the data on gender, age, origin of the lesion, nerve, interval between surgery and onset of laser therapy, frequency of laser irradiation (one or two times per week), final evolution, and if there was a need to change the irradiation protocol, were all recorded. These data were related to the recovery of sensitivity in the affected nerve area. Descriptive analyses and modeling for analysis of categorical data (α=5%) were performed. The results from both analyses showed that the recovery of sensitivity was correlated with patient age (p=0.015) and interval between surgery and onset of laser therapy (p=0.002). Within the limits of this retrospective study, it was found that low- power laser therapy with beam emission band in the infrared spectrum (808 nm) can positively affect the recovery of sensitivity after orthognathic or minor oral surgeries.

Clinical courses following two-stage mandibular wisdom tooth extraction (TMWTE) carried out for preventing postoperative mental nerve paresthesia (MNP) were analyzed. When panoramic X-ray showed overlapping of wisdom tooth root on the superior 1/2 or more of the mandibular canal, interruption of the white line of the superior wall of the canal, or diversion of the canal, CT examination was facilitated. In cases where contact between the tooth root and canal was demonstrated in CT examination, TMWTE was then selected after gaining the patient's consent. TMWTE consisted of removing more than a half of the tooth crown and tooth root extraction at the second step after 2-3 months. The clinical features of wisdom teeth extracted and postoperative courses including tooth movement and occurrence of MNP during two-stage MWTE were evaluated. TMWTE was carried out for 40 teeth among 811 wisdom teeth (4.9%) that were extracted from 2007 to 2009. Among them, complete procedures were accomplished in 39 teeth, and crown removal was performed insufficiently at the first-stage operation in one tooth. Tooth movement was detected in 37 of 40 cases (92.5%). No postoperative MNP was observed in cases in which complete two-stage MWTE was carried out, but one case with insufficient crown removal was complicated by postoperative MNP. Seven mild complications (dehiscence, cold sensitivity, etc.) were noted after the first-stage operation. Therefore, we conclude that TMWTE for high-risk cases assessed by X-ray findings is useful to avoid MNP after MWTE. (author)

A multicenter study was initiated to evaluate the performance of the transverse tripolar system for spinal cord stimulation. Computer modeling had predicted steering of paresthesia with a dual channel stimulator to be the main benefit of the system. The quantitative analysis presented here includes the results of 484 tests in 30 patients. For each test, paresthesia coverage as a function of voltage levels was stored in a computerized database, including a body map which enabled calculation of the degree of paresthesia coverage of separate body areas, as well as the overlap with the painful areas. The results show that with the transverse tripolar system steering of the paresthesia is possible, although optimal steering requires proper placement of the electrode with respect to the spinal cord. Therefore, with this steering ability as well as a larger therapeutic stimulation window as compared to conventional systems, we expect an increase of the long-term efficacy of spinal cord stimulation. Moreover, in view of the stimulation-induced paresthesia patterns, the system allows selective stimulation of the medial dorsal columns.

Diagnostic lumbosacral segmental nerve blocks with local anesthetics: a prospective double-blind study on the variability and interpretation of segmental effects.

Science.gov (United States)

Wolff, A P; Groen, G J; Crul, B J

Selective spinal nerve infiltration blocks are used diagnostically in patients with chronic low back pain radiating into the leg. Generally, a segmental nerve block is considered successful if the pain is reduced substantially. Hypesthesia and elicited paresthesias coinciding with the presumed segmental level are used as controls. The interpretation depends on a standard dermatomal map. However, it is not clear if this interpretation is reliable enough, because standard dermatomal maps do not show the overlap of neighboring dermatomes. The goal of the present study is to establish if dissimilarities exist between areas of hypesthesia, spontaneous pain reported by the patient, pain reduction by local anesthetics, and paresthesias elicited by sensory electrostimulation. A secondary goal is to determine to what extent the interpretation is improved when the overlaps of neighboring dermatomes are taken into account. Patients suffering from chronic low back pain with pain radiating into the leg underwent lumbosacral segmental nerve root blocks at subsequent levels on separate days. Lidocaine (2%, 0.5 mL) mixed with radiopaque fluid (0.25 mL) was injected after verifying the target location using sensory and motor electrostimulation. Sensory changes (pinprick method), paresthesias (reported by the patient), and pain reduction (Numeric Rating Scale) were reported. Hypesthesia and paresthesias were registered in a standard dermatomal map and in an adapted map which included overlap of neighboring dermatomes. The relationships between spinal level of injection, extent of hypesthesia, location of paresthesias, and corresponding dermatome were assessed quantitatively. Comparison of the results between both dermatomal maps was done by paired t-tests. After inclusion, data were processed for 40 segmental nerve blocks (L2-S1) performed in 29 patients. Pain reduction was achieved in 43%. Hypesthetic areas showed a large variability in size and location, and also in comparison to

A new type of spinal cord stimulation electrode, providing contact combinations with a transverse orientation, is presented. Electrodes were implanted in the cervical area (C4-C5) of two chronic pain patients and the stimulation results were subsequently simulated with a computer model consisting of a volume conductor model and active nerve fiber models. For various contact combinations a good match was obtained between the modeling results and the measurement data with respect to load resistance (less than 20% difference), perception thresholds (16% difference), asymmetry of paresthesia (significant correlation) and paresthesia distributions (weak correlation). The transversally oriented combinations provided the possibility to select either a preferential dorsal column stimulation, a preferential dorsal root stimulation or a mixed stimulation. The (a)symmetry of paresthesia could largely be affected in a predictable way by the selection of contact combinations as well. The transverse tripolar combination was shown to give a higher selectivity of paresthesia than monopolar and longitudinal dipolar combinations, at the cost of an increased current (more than twice).

Bilateral endoscopic endonasal marsupialization of nasopalatine duct cyst

Directory of Open Access Journals (Sweden)

Yohei Honkura

2015-02-01

Full Text Available Nasopalatine duct cysts are the most common non-odontogenic cysts in the maxilla, and are conventionally treated through a sublabial or palatine approach. Recently, the endoscopic approach has been used, but experience is extremely limited. We treated a 29-year-old male with nasopalatine duct cyst by endoscopic marsupialization, but paresthesia of the incisor region occurred after surgery. This paresthesia gradually remitted within 6 months. The nasopalatine nerve, which innervates the upper incisor region, enters two lateral canals separately at the nasal floor and exits the central main canal at the palate. Damage to the bilateral nasopalatine nerves might lead to paresthesia, so we recommend careful examination for nerve fibers during endoscopic surgery, especially if fenestration is performed on both sides.

Focused studies on sensory manifestations, especially pain and paresthesia in Guillain-Barre' (GB) syndrome are few and far between. To study the sensory manifestations in GB syndrome during 10 days of hospitalization with clinico-electrophysiological correlation. The study included 60 non-consecutive patients with GB syndrome, fulfilling National Institute of Neurological and Communicative Disorders and Stroke (NINCDS) criteria for GB syndrome. Data especially related to clinical and electrophysiological evidence of sensory involvement were analyzed. Pain was assessed using a) visual analogue paraesthesias (Vapar), b) visual analogue for pain (Vap) and c) verbal rating scale for pain (Verp). Sensory symptoms were widely prevalent: paraesthesia in 45 (75%) patients and pain in 30 (50%) patients. Impairment of different sensory modalities included: pain in 8 (13.3%), joint position sense in 14 (23.3%), and vibration in 11 (18.3%). Electrophysiological evidence of abnormal sensory nerve conduction was noted in 35 (58.3%) patients. Pain assessment using Vapar, Vap and Verp for from Day 1 to Day 10 of hospitalization revealed that from Day 7 onwards the degree and frequency of sensory symptoms and signs decreased. On comparing various clinico-electrophysiological parameters among patients of GB syndrome with and without pain and paresthesia. Presence of respiratory distress correlated with pain and paresthesia (P=0.02). Sensory manifestations in GB syndrome are often under-recognized and under-emphasized. This study analyzed the evolution and the profile of pain and paresthesia in GB syndrome during hospitalization. Knowledge, especially about evolution of pain and paresthesia during hospitalization might improve understanding and patient care.

Many studies have demonstrated the efficacy and the medical/economic value of epidural spinal cord stimulation for the treatment of "failed back surgery syndrome" (FBSS). However, the back pain component of FBSS has been recalcitrant. Recent clinical trials have suggested that multicolumn surgically implanted leads combined with enhanced programming capabilities in the newer implantable pulse generators demonstrate the ability to treat the back pain component of FBSS. The objective of our present international multicentre study is to prospectively evaluate these findings in a larger population. We conducted a prospective, nonrandomized, observational study on 76 patients with refractory FBSS, consecutively implanted with multicolumn spinal cord stimulation (SCS) between 2008 and 2011 in three neurosurgical pain management centers (Poitiers, France; Montréal, Canada; and Regina, Canada). The primary objective of this study was to prospectively analyze the effect of multicolumn lead programming on paresthesia coverage for the back pain region in these patients. The secondary objective was to assess the analgesic efficacy of this technique on the global and back pain components. Paresthesia could be induced in the lower extremities in the majority of patients with at least one of the configurations tested. Bilateral low back paresthesia was induced in 53.5% of patients, while unilateral low back paresthesia was induced in 78.9% of patients. Multicolumn configurations were statistically more effective than monocolumn configurations for all anatomic regions studied. At 6 months, 75.4% of patients receiving multicolumn stimulation (n = 57) obtained at least a 30% improvement of the back pain VAS score, while 42.1% of patients obtained at least a 50% improvement of the back pain VAS score. This study confirms the hypothesis that multicolumn SCS should be considered as an important tool in the treatment of radicular and axial pain in FBSS patients. The efficacy of this

Kirkpatrick, J N

1987-01-01

A syndrome of headache, fatigue, dizziness, paresthesias, chest pain, palpitations and visual disturbances was associated with chronic occult carbon monoxide exposure in 26 patients in a primary care setting. A causal association was supported by finding a source of carbon monoxide in a patient's home, workplace or vehicle; results of screening tests that ruled out other illnesses; an abnormally high carboxyhemoglobin level in 11 of 14 patients tested, and abatement or resolution of symptoms when the source of carbon monoxide was removed. Exposed household pets provided an important clue to the diagnosis in some cases. Recurrent occult carbon monoxide poisoning may be a frequently overlooked cause of persistent or recurrent headache, fatigue, dizziness, paresthesias, abdominal pain, diarrhea and unusual spells.

Disturbances of sensation occasioned by experimental arrest of blood flow

Alfred Auersperg

1949-12-01

Full Text Available Disturbances of sensation in the hand were studied during and after experimental arrest of circulation to the arm. Blockage of circulation was performed as outlined by Lewis and Pochin, by putting the cuff of a sphygmomanometer on the upper arm and bringing the pressure rapidly up to 200 mm/Hg. The experiments listed below were intended to demonstrate the variability of a central reaction brought about by fairly definite disturbances of the ischaemic periphery. All experiments were made on the present writers and repeated on nine other subjects, none of whom had systolic pressure reaching 150 mm/Hg. I - Blockage of circulation in both arms led to symmetrical phenomena in both hands (thermal paresthesias, tingling and hyposthesia, both under symmetrical experimental circumstances, and under the following variations: So long as the cuff pressure on both arms was above the systolic blood pressure, differences as great as 300 mm/Hg in one cuff and 150 mm in the other did not alter the symmetry of the effects. Neither was symmetry and synchronism of paresthesias affected when compression on one side preceded equal compression on the other up to 20 seconds. II - When a punctate pressure is applied to the paresthetic field the paresthesias disappear around that point and the latter is clearly brought out from the indifferent background produced in the area of depressed skin. On the basis of Kugelberg's findings, it seems that this occurs because the impulses caused by pressure have a higher frequency and substitute the spontaneous abnormal discharges of the ischaemic nerve fibers. III - Repeated mechanical stimulation of a fingertip during the experiment failed to show any influence on sensory (touch thresholds, in contrast, therefore, to what would be expected on the basis of the physiologic experiments which show rapid fatigue of ischaemic structures. IV - In contrast to what might be expected from the intense changes undergone by receptors in the

Due to long-term use of peripheral veins and arteriovenous fistula (AVF failure, central venous catheterization was the only choice for hemodialysis. She developed right upper extremiti’s pain and paresis during hemodialysis. A posteroanterior chest x-ray showed the catheter tip was accidently pushed from right internal jugular vein into right subclavian vein during hemodialysis by the dialysis center nurse. Therefore, we believe that the physician should be aware of any changes in the catheter size after insertion. And a chest x-ray should ensure the catheter’s correct position in any patient who develops complications.

To take high resolution manometry in 44 cases of pharyngeal paraesthesia patients and 23 normal subjects separately. According to the RSI score,the 44 patients were divided into group A (the group without reflux, RSI 0.05). The esophagus DCI of group B was lower than that of group A and control group (P 0.05). The pharyngeal paresthesia symptoms of'patients was associated with the increasing of UES pressure. The pharyngeal paresthesia symptoms of group with reflux was related to low pressure of LES and high pressure of UES. The last part of esophagus of group with reflux had obstacles in powers, which weaken the peristalsis and declined the ability to clear the bolus and gastric reflux material.

Improved spatial targeting with directionally segmented deep brain stimulation leads for treating essential tremor

Science.gov (United States)

Keane, Maureen; Deyo, Steve; Abosch, Aviva; Bajwa, Jawad A.; Johnson, Matthew D.

2012-08-01

Deep brain stimulation (DBS) in the ventral intermediate nucleus of thalamus (Vim) is known to exert a therapeutic effect on postural and kinetic tremor in patients with essential tremor (ET). For DBS leads implanted near the caudal border of Vim, however, there is an increased likelihood that one will also induce paresthesia side-effects by stimulating neurons within the sensory pathway of the ventral caudal (Vc) nucleus of thalamus. The aim of this computational study was to (1) investigate the neuronal pathways modulated by therapeutic, sub-therapeutic and paresthesia-inducing DBS settings in three patients with ET and (2) determine how much better an outcome could have been achieved had these patients been implanted with a DBS lead containing directionally segmented electrodes (dDBS). Multi-compartment neuron models of the thalamocortical, cerebellothalamic and medial lemniscal pathways were first simulated in the context of patient-specific anatomies, lead placements and programming parameters from three ET patients who had been implanted with Medtronic 3389 DBS leads. The models showed that in these patients, complete suppression of tremor was associated most closely with activating an average of 62% of the cerebellothalamic afferent input into Vim (n = 10), while persistent paresthesias were associated with activating 35% of the medial lemniscal tract input into Vc thalamus (n = 12). The dDBS lead design demonstrated superior targeting of the cerebello-thalamo-cortical pathway, especially in cases of misaligned DBS leads. Given the close proximity of Vim to Vc thalamus, the models suggest that dDBS will enable clinicians to more effectively sculpt current through and around thalamus in order to achieve a more consistent therapeutic effect without inducing side-effects.

Three dimensional titanium plating system was developed by Farmand in 1995 to meet the requirements of semi rigid fixation with lesser complication. The purpose of this in vivo prospective study was to evaluate and compare the clinical effectiveness of three dimensional and two dimensional Titanium miniplates for open reduction and fixation of mandibular parasymphysis fracture. Thirty patients with non-comminuted mandibular parasymphysis fractures were divided randomly into two equal groups and were treated with 2 mm 3D and 2D miniplate system respectively. All patients were systematically monitored at 1st, 2nd, 3rd, 6th week, 3rd and 6th month postoperatively. The outcome parameters recorded were severity of pain, infection, mobility, occlusion derangement, paresthesia and implant failure. The data so collected was analyzed using independent t test and Chi square test (α = .05). The results showed that one patient in each group had post-operative infection, occlusion derangement and mobility (p > .05). In Group A, one patient had paresthesia while in Group B, two patients had paresthesia (p > .05). None of the patients in both the groups had implant failure. There was no statistically significant difference between 3D and 2D miniplate system in all the recorded parameters at all the follow-ups (p > .05). 3D miniplates were found to be better than 2D miniplates in terms of cost, ease of surgery and operative time. However, 3D miniplates were unfavorable for cases where fracture line was oblique and in close proximity to mental foramen, where they were difficult to adapt and more chances for tooth-root damage and inadvertent injury to the mental nerve due to traction.

Spinal Cord Stimulation in Chronic Pain: Mode of Action.

Vallejo, Ricardo; Bradley, Kerry; Kapural, Leonardo

2017-07-15

Literature review. A review of the literature that presents a perspective on mechanisms of actions behind spinal cord stimulation (SCS) therapy for chronic pain. SCS is an effective therapeutic alternative for the treatment of intractable chronic pain. Its application has been mostly based on the gate control theory of pain. Computational models have been fundamental on the understanding of clinical observations and the design of therapies that provide optimal neuromodulation. Research has provided insight into the involvement of specific neurotransmitters that support segmental and supraspinal mechanisms of action. A literature review was performed with emphasis on mechanisms of action for SCS including the effects of electrical fields on spinal cord structures based on computational models and preclinical and clinical explorations. This review provides background on the development of SCS, which has been driven around a paresthesia-based paradigm as a result of the gate control theory. A review of computational models emphasizes their importance on our current understanding of the mechanism of action and clinical optimization of therapy. Electrophysiology and molecular biology have provided a closer, yet narrow, view of the effect of SCS on neurotransmitters and their receptors, which have led to the formulation of segmental and supraspinal mechanisms. Literature supporting the involvement of glial cells in chronic pain and their characteristic response to electrical fields should motivate further investigation of mechanisms involving neuroglia. Finally, a review of recent results paresthesia-free strategies should encourage research on mechanisms of action. The mechanisms of SCS have been extensively studied and several consistent phenomena have emerged. The activation of A-beta fibers to induce paresthesia also involve neurotransmitter release via segmental and supraspinal pathways. Despite advancements, much remains to be understood, particularly as new

Selective Radiofrequency Stimulation of the Dorsal Root Ganglion (DRG) as a Method for Predicting Targets for Neuromodulation in Patients With Post Amputation Pain: A Case Series.

While spinal cord stimulation (SCS) has established itself as an accepted and validated treatment for neuropathic pain, there are a number of conditions where it has experienced less, long-term success: post amputee pain (PAP) being one of them. Dorsal root ganglion (DRG) stimulation has shown great promise, particularly in conditions where traditional SCS has fallen short. One major difference between DRG stimulation and traditional SCS is the ability to provide focal stimulation over targeted areas. While this may be a contributing factor to its superiority, it can also be a limitation insofar stimulating the wrong DRG(s) can lead to failure. This is particularly relevant in conditions like PAP where neuroplastic maladaptation occurs causing the pain to deviate from expected patterns, thus creating uncertainty and variability in predicting targets for stimulation. We propose selective radiofrequency (RF) stimulation of the DRG as a method for preoperatively predicting targets for neuromodulation in patients with PAP. We present four patients with PAP of the lower extremities. RF stimulation was used to selectively stimulate individual DRG's, creating areas of paresthesias to see which most closely correlated/overlapped with the painful area(s). RF stimulation to the DRG's that resulted in the desirable paresthesia coverage in the residual or the missing limb(s) was recorded as "positive." Trial DRG leads were placed based on the positive RF stimulation findings. In each patient, stimulating one or more DRG(s) produced paresthesias patterns that were contradictory to know dermatomal patterns. Upon completion of a one-week trial all four patients reported 60-90% pain relief, with coverage over the painful areas, and opted for permanent implant. Mapping the DRG via RF stimulation appears to provide improved accuracy for determining lead placement in the setting of PAP where pain patterns are known to deviate from conventional dermatomal mapping. © 2017

Full Text Available Rostral spread of intrathecal drugs and sensitization of supraspinal sites may provoke several adverse effects. This case describes a patient with right hemifacial paresthesia, trismus and dysphasia on the trigeminal nerve distribution after intrathecal sufentanil administration. Primigravida, 34 years, 39 weeks of pregnancy, with hypothyroidism and pregnancy induced hypertension. Allergic to latex. In the use of puran T4, 50 μg /day. When the patient presented cervical dilatation of 4 cm, she requested analgesia. She was placed in the sitting position and a spinal puncture was performed with a 27G needle pencil point in L4/L5 (1.5 mg of bupivacaine plus 7.5 μg of sufentanil. Next, was performed an epidural puncture in the same space. It was injected bupivacaine 0.065%, 10 ml, to facilitate the passage of the catheter. After 5 min lying down in the lateral upright position, she complained of perioral and right hemifacial paresthesia, mainly maxillary and periorbital, as well as trismus and difficulty to speak. The symptoms lasted for 30 min and resolved spontaneously. After 1 h, patient requested supplementary analgesia (12 ml of bupivacaine 0.125% and a healthy baby girl was born. Temporary mental alterations have been described with the use of fentanyl and sufentanil in combined epidural-spinal analgesia, such as aphasia, difficulty of swallowing, mental confusion and even unconsciousness. In this patient, facial areas with paresthesia indicated by patient appear in clear association with the ophthalmic and maxillary branches of the trigeminal nerve and the occurrence of trismus and dysphagia are in association with the mandibular motor branch. The exact mechanism of rostral spread is not known, but it is speculated that after spinal drug administration, a subsequent epidural dose may reduce the intratecal space and propel the drug into the supraspinal sites.

Acute herpes simplex virus (HSV) infection was detected in 23 of 102 consecutively examined, sexually active male homosexuals who presented with anorectal pain, discharge, tenesmus, or hematochezia, as compared with 3 of 75 homosexual men without gastrointestinal symptoms (P less than 0.01). Findings that were significantly more frequent in men with HSV proctitis than in men with proctitis due to other infectious causes included fever (48 per cent), difficulty in urinating (48 per cent), sacral paresthesias (26 per cent), inguinal lymphadenopathy (57 per cent), severe anorectal pain (100 per cent), tenesmus (100 per cent), constipation (78 per cent), perianal ulcerations (70 per cent), and the presence of diffuse ulcerative or discrete vesicular or pustular lesions in the distal 5 cm of the rectum (50 per cent). Serologic evidence indicated that 85 per cent of the men with symptomatic HSV proctitis were having their first episode of HSV-2 infection. The diagnosis of HSV proctitis is suggested by the presence of severe anorectal pain, difficulty in urinating, sacral paresthesias or pain, and diffuse ulceration of the distal rectal mucosa.

Carpometacarpal subchondral cysts due to repetitive movements in shoemaker: a case report.

2011-12-01

Subchondral carpometacarpal cysts are classic and almost pathognomonic lesions found in workers using vibrating instruments over prolonged periods of time. We present the case of a 53-year-old woman who worked for 30 years sewing shoe uppers, a task which required grasping firmly a pear-shaped handle awl and pushing it through the leather upper and the sole of the shoe, with combined flexion and supination movement of the wrist. After approximately 20 years of working, the patient noted gradual onset of paresthesias in the dominant (right) hand, with increasing difficulty in grasping the awl. Subsequent diagnosis of carpal tunnel syndrome was confirmed by electrophysiologic testing and its surgical release was performed. Nevertheless, hand pain, paresthesias and weakness persisted. Ultrasound of the snuffbox tendons excluded DeQuervain tenosynovitis. Radiographic imaging of the symptomatic hand showed carpometacarpal subchondral cystic formations. In addition to demonstrating the usefulness of radiographic imaging in patients with persistent hand pain post-carpal release, this case is important in illustrating that repetitive movements with high pressure over the palmar carpal area may cause bone cysts, even if the subjects do not use vibrating tools.

2011-07-01

The minimally invasive transpsoas interbody fusion technique requires dissection through the psoas muscle, which contains the nerves of the lumbosacral plexus posteriorly and genitofemoral nerve anteriorly. Retraction of the psoas is becoming recognized as a cause of transient postoperative thigh pain, numbness, paresthesias, and weakness. However, few reports have described the nature of thigh symptoms after this procedure. The authors performed a review of patients who underwent the transpsoas technique for lumbar spondylotic disease, disc degeneration, and spondylolisthesis treated at a single academic medical center. A review of patient charts, including the use of detailed patient-driven pain diagrams performed at equal preoperative and follow-up intervals, investigated the survival of postoperative thigh pain, numbness, paresthesias, and weakness of the iliopsoas and quadriceps muscles in the follow-up period on the ipsilateral side of the surgical approach. Over a 3.2-year period, 59 patients underwent transpsoas interbody fusion surgery. Of these, 62.7% had thigh symptoms postoperatively. New thigh symptoms at first follow-up visit included the following: burning, aching, stabbing, or other pain (39.0%); numbness (42.4%); paresthesias (11.9%); and weakness (23.7%). At 3 months postoperatively, these percentages decreased to 15.5%, 24.1%, 5.6%, and 11.3%, respectively. Within the patient sample, 44% underwent a 1-level, 41% a 2-level, and 15% a 3-level transpsoas operation. While not statistically significant, thigh pain, numbness, and weakness were most prevalent after L4-5 transpsoas interbody fusion at the first postoperative follow-up. The number of lumbar levels that were surgically treated had no clear association with thigh symptoms but did correlate directly with surgical time, intraoperative blood loss, and length of hospital stay. Transpsoas interbody fusion is associated with high rates of immediate postoperative thigh symptoms. While larger

ERYTHEMA ELEVATUM DIUTINUM AS MOST PROBABLE DIAGNOSIS: A CASE REPORT

Directory of Open Access Journals (Sweden)

Erick Francisco Sanchez Jimenez

2013-07-01

Full Text Available Cutaneous vasculitis can be cause by multiple disorders or can be idiopathic. Many diseases can present with similar findings, therefore histopathologic examination is always require for confirming the right diagnosis. The erythema elevatum diutinum (EED is a localized vasculitis, classified as a neutrophilic dermatosis. It’s a rare cutaneous condition, distribute on the extensor surface of the extremities, more frequently in the dorsum of the hands, knees and elbows. They have a symmetric distribution and can be asymptomatic, painful; or pruritic, sometimes accompanied paresthesias. The most common clinical presentation is round erythematous papules which become erythemato-violaceous or purpuric plaques. There are not pathognomonic histopathological findings, but can present as a leukocytoclastic vasculitis with perivascular neutrophilic infiltration in the middle and superficial dermis. I presented the case of a 61-year-old female, with erythematous purpuric painful plaques, irregular, symmetric and elevated, located in both thenar regions of her hands and paresthesias. The patient’s presentation is consistent with multiple characteristics of EED such as the description of the lesions, the anatomical location, the symmetric distribution and the histopathological findings of an initial disease. This patient does not have all the clinical progression and outcome, due to the initial stage of the disease.

Spinal Anesthesia and Minimal Invasive Laminotomy for Paddle Electrode Placement in Spinal Cord Stimulation: Technical Report and Clinical Results at Long-Term Followup

S. Sarubbo

2012-01-01

Full Text Available Object. We arranged a mini-invasive surgical approach for implantation of paddle electrodes for SCS under spinal anesthesia obtaining the best paddle electrode placement and minimizing patients’ discomfort. We describe our technique supported by neurophysiological intraoperative monitoring and clinical results. Methods. 16 patients, affected by neuropathic pain underwent the implantation of paddle electrodes for spinal cord stimulation in lateral decubitus under spinal anesthesia. The paddle was introduced after flavectomy and each patient confirmed the correct distribution of paresthesias induced by intraoperative test stimulation. VAS and patients’ satisfaction rate were recorded during the followup and compared to preoperative values. Results. No patients reported discomfort during the procedure. In all cases, paresthesias coverage of the total painful region was achieved, allowing the best final electrode positioning. At the last followup (mean 36.7 months, 87.5% of the implanted patients had a good rate of satisfaction with a mean VAS score improvement of 70.5%. Conclusions. Spinal cord stimulation under spinal anesthesia allows an optimal positioning of the paddle electrodes without any discomfort for patients or neurosurgeons. The best intraoperative positioning allows a better postoperative control of pain, avoiding the risk of blind placements of the paddle or further surgery for their replacement.

The carpal tunnel syndrome (CTS) is a common working pathology. The CTS diagnosis is not so easy because neurophysiological investigations are necessary. The purpose of this study is to evaluate the working risks and the presence of CTS signs using a focused anamnestic and clinical procedure. We evaluated the working risks of CTS in a population of 65 male workers of a steel industry (average age 25.1 and seniority 2.82), performing 5 different tasks. The Borg Scale was used to evaluate the subjective muscle effort. Diurnal paresthesia (V1FG), nocturnal paresthesia (V1FN), hypersensitivity (V1IS), hypostenia (V1IT) were considered. We identified three main working risks repetitiveness of single actions, static and prolonged posture of the truck, muscle effort. 21.5% of the workers showed at least one of the three symptoms;13.8% showed one or more symptoms; the clinical objectivity was observed in 18.5%. A relation between V1FG, V1FN, clinical objective linked to the workers age of the task 1 (p =0.035) is showed. To prevent CTS, the use of the Borg Scale associated with identification of the risks and with the anamenstic-clinical investigation is useful to discriminate people at risk of CTS.

2015-01-01

Background Whether or not uniportal video-assisted thoracoscopic surgery (VATS) is beneficial for spontaneous pneumothorax remains inconclusive. This meta-analysis aimed to summarize the available evidence to assess the feasibility and advantages of uniportal VATS for the treatment of spontaneous pneumothorax compared with three-port VATS. Methods Eligible publications were identified by searching the Cochrane Library, PubMed, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Data databases and CQVIP. Odds ratios (OR) and standardized mean differences (SMD) with 95% confidence intervals (CI) were calculated to compare dichotomous and continuous variables, respectively. Results This meta-analysis was based on 17 studies and included a total of 988 patients with spontaneous pneumothorax. No death was reported during the perioperative period. Compared with three-port VATS groups, there was a statistically significant difference in uniportal VATS groups regarding postoperative hospital stay (SMD= −0.58; 95% CI: −1.04 to −0.12; P=0.01), paresthesia (OR=0.13; 95% CI: 0.07 to 0.24; Pparesthesia as well as an improvement in patients’ satisfaction. This meta-analysis indicated that using uniportal VATS to treat spontaneous pneumothorax was safe and feasible, and it may be a better alternative procedure because of its advantage in reducing postoperative pain and paresthesia.

2013-01-01

Background: Post-dural puncture headache (PDPH) is a common problem in anaesthesia practice especially in obstetric anaesthesia. Autologous epidural blood patch (AEBP) is the main stay of treatment of PDPH when it is not relieved with conservative management. Objective: To describe the efficacy of AEBP in treatment of PDPH. Study Design: Prospective descriptive study. Setting and Duration: The study was conducted at departments of Anaesthesia and Intensive Care, Military Hospital, Rawalpindi and Combined Military Hospital, Malir, from July 2008 to July 2011. Methodology: All patients who received AEBP during study period secondary to PDPH were included. Up to 20 ml of autologous blood was injected in epidural space. Effectiveness of AEBP was judged by relief of symptom; any complications associated with AEBP i.e. backache and paresthesia were also noted. Data was interpreted as mean and percentages. Results: A total of 30 AEBP were performed during the study period in predominantly female patients (n=27) with mean age of 27.8 years. AEBP was performed after a mean 3.83 days of lumbar puncture. Complete relief was observed in 29 (96%) patients; one patient required a second patch. During the follow-up, 7 (23%) patients complained of backache and 2(6%) of paresthesias. conclusion: AEBP is an effective way of providing relief from PDPH. (author)

Occult Carbon Monoxide Poisoning

Morbidity after conventional dissection of axillary lymph nodes in breast cancer patients

Science.gov (United States)

2014-01-01

Background Conventional axillary lymph node dissection (ALND) has recently become less radical. The treatment morbidity effects of reduced ALND aggressiveness are unknown. This article investigates the prevalence of the main complications of ALND: lymphedema, range-of-motion restriction, and arm paresthesia and pain. Methods This cross-sectional study included 200 women with invasive breast cancer who underwent breast-conserving surgery (82.5%, n = 165) or mastectomy (17.5%, n = 35) with ALND from 2007 to 2011. Arm perimetry was used to assess lymphedema, defined as a difference >2 cm in the upper arm circumference between the nonsurgical and surgical arms. Range-of-motion restriction was assessed by evaluating the degree of arm abduction. Paresthesia was measured in the inner and proximal arm regions. Arm pain was assessed by directly questioning the patients and defined as either present or absent. Results The average (±SD) time between ALND and morbidity evaluation was 35 ± 18 months (range, 7-60 months). The average dissected lymph node number per patient was 14 ± 4 (range, 6-30 lymph nodes). Only 3.5% (n = 7) of the patients presented with lymphedema. Single-incision approaches to breast tumor and ALND (P = 0.04) and the presence of a postoperative seroma (P = 0.02) were associated with lymphedema in univariate analysis. Paresthesia was the most frequent side effect observed (53% of patients, n = 106). This complication was associated with increased age (P < 0.0001) and a larger dissected lymph node number (P = 0.01) in univariate and multivariate analysis. Additionally, 24% (n = 48) of patients had noticeable limited arm abduction. Among the patients, 27.5% (n = 55) experienced sporadic arm pain corresponding to the surgically treated armpit. In multivariate analysis, the pain risk was 1.9-fold higher in patients who underwent ALND corresponding to their dominant arm (95% CI, 1.0-3.7, P = 0

Chemotherapy-induced peripheral neuropathy is a debilitating side effect of chemotherapy, which manifests as paresthesias, dysesthesias, and numbness in the hands and feet. Numerous chemoprotective agents and treatments have been used with limited success to treat chemotherapy-induced peripheral neuropathy. We report a case in which a patient presenting with chemotherapy-induced peripheral neuropathy received an IV lidocaine infusion over the course of 60 minutes with complete symptomatic pain relief for a prolonged period of 2 weeks.

2014-01-01

The carpal tunnel syndrome (CTS) is the most common cause of severe hand pain. In this study we treated acute pain in CTS patients by means of local intradermal injections of anti-inflammatory drugs (mesotherapy). In twenty-five patients (forty-five hands), CTS diagnosis was confirmed by clinical and neurophysiological examination prior to mesotherapy. A mixture containing lidocaine 10 mg, ketoprophen lysine-acetylsalycilate 80 mg, xantinol nicotinate 100 mg, cyanocobalamine 1,000 mcg plus injectable water was used. Sites of injection were three parallel lines above the transverse carpal ligament and two v-shaped lines, one at the base of the thenar eminence, and the other at the base of the hypothenar eminence. The day after the treatment, all but four patients reported a significant reduction in pain and paresthesias. After 12 months, 17 patients had a complete pain relief, eight patients reported recurrence of pain and sensory symptoms and four out of them underwent surgical treatment. With the obvious limits of a small-size open-label study, our results suggest that mesotherapy can temporary relieve pain and paresthesias in most CTS patients and in some cases its effect seems to be long-lasting. Further controlled studies are needed to confirm our preliminary findings and to compare mesotherapy to conventional approaches for the treatment of CTS.

To evaluate the safety and efficacy of retrograde endovenous laser ablation (EVLA) and to compare it with the conventional antegrade EVLA for incompetent small saphenous vein (SSV). Small saphenous vein was cannulated via two approaches under ultrasound-guidance. One method involved puncturing the SSV cranially at mid-calf (the antegrade group). If the antegrade puncture into the SSV failed twice, the other approach for puncture was selected that involved puncturing the SSV toward the ankle (the retrograde group). Patients were evaluated in terms of technical and clinical success, closure rates of the SSV, and complications including pain, bruising, or paresthesia at all follow-up visits. The 1470 nm endovenous laser was used in all limbs. Technical success was seen in all limbs in both groups (100%). Closure rate in both groups showed about 95%, without significant difference (p = 0.685). Similar linear endovenous energy density was supplied during the EVLA in both groups (p = 0.876). Three frequent complications including bruising, pain, and paresthesia did not show statistical significance between groups (p = 0.465, 0.823, 1.000, respectively). Major complications were absent in both groups. The EVLA for the incompetent SSV using a retrograde approach is safe and effective and should be considered the alternative method if the antegrade access fails due to vasospasm or small SSV diameter.

Five years' experience of transverse groin incision for femoral artery access in arterial reconstructive surgery: parallel observational longitudinal group comparison study.

LENUS (Irish Health Repository)

Beirne, Christopher

2008-07-01

Vertical groin incisions (VGIs) have been used to access femoral vessels, but reports allude to wound complications. Our aim was to compare VGI with transverse groin incision (TGI) for femoral artery exposure. Over a 5-year interval, 196 patients with 284 femoral artery exposures for supra- and infrainguinal procedures were studied. Primary endpoints were surgical skin site wound infection, seroma, haematoma formation, and major lower limb amputation. Secondary endpoints were graft patency, wound paresthesias, and length of hospital stay. There were 160 TGIs and 124 VGIs. The demographics and risk factor profile were not statistically different between groups. Seroma developed in 4.4% of TGIs and 13.7% of VGIs (p= .005). The complicated skin and soft tissue infection rate was five times greater with VGI (p= .001). The VGI group had a significantly higher rate of major amputation (p= .0005). Significantly higher graft failure rates were observed in the VGI group (p= .011). No paresthesia was reported in any TGI wound. The mean hospital stay was also significantly shorter in the TGI group (p= .006). The study data support and expound on the theory that an alternative incision to VGI offers lower short- and long-term morbidity. Our findings sustain the selection of the TGI in femoral artery surgery for both supra- and infrainguinal procedures without compromise of vessel exposure.

Sciatic nerve injuries following total hip arthroplasty are disabling complications. Although degrees of injury are variable from neuropraxia to neurotmesis, mechanical irritation of sciatic nerve might be occurred by protruding hardware. This case shows endoscopic decompression for protruded acetabular screw irritating sciatic nerve, the techniques described herein may permit broader arthroscopic/endoscopic applications for management of complications after reconstructive hip surgery. An 80-year-old man complained of severe pain and paresthesias following acetabular component revision surgery. Physical findings included right buttock pain with radiating pain to lower extremity. Radiographs and computed tomography imaging showed that the sharp end of protruded screw invaded greater sciatic foramen anterior to posterior and distal to proximal direction at sciatic notch level. A protruding tip of the acetabular screw at the sciatic notch was decompressed by use of techniques gained from experience performing endoscopic sciatic nerve decompression. The pre-operative pain and paresthesias resolved post-operatively after recovering from anesthesia. This case report describes the first documented endoscopic resection of the tip of the acetabular screw irritating sciatic nerve after total hip arthroplasty. If endoscopic resection of an offending acetabular screw can be performed in a safe and minimally invasive manner, one can envision a future expansion of the role of hip arthroscopic surgery in several complications management after total hip arthroplasty.

Full Text Available Background and objective: The close proximity of lingual nerve in relation to the lingual cortical bone of the posterior mandibular third molar is clinically important because lingual nerve may be subjected to trauma during surgical removal of the impacted lower third molar. This prospective study aimed to evaluate the incidence of lingual nerve paresthesia following surgical removal of mandibular third molar in College of Dentistry, Hawler Medical University. Methods: A total of 116 third molars surgery were carried out under local anesthesia for 116 patients for removal of lower mandibular teeth Using Terence Ward's incision made in all cases, and after that, the buccal flap was reflected, lingual tissues had been retracted during bone removal with a periosteal elevator. The sensory disturbance was evaluated on the 7th postoperative day by standard questioning the patients: “Do you have any unusual feeling in your tongue, lingual gingiva and mucosa of the floor of the mouth?" Results: One patient experienced sensory disturbance, the lingual nerve paresthesia incidence was 0.9% as a transient sensory disturbance, while no patient of permanent sensory disturbance. Conclusion: The incidence of injury to the lingual nerve can be minimized by careful clinical evaluation, surgeon’s experience, surgical approach and knowledge about anatomical landmarks during surgical removal of an impacted lower third molar tooth.

Conventional spinal cord stimulation (SCS) delivers a tonic waveform with consistent stream of pulses; burst delivers groups of pulses separated by short pulse-free periods. The current study compared the short-term safety and efficacy of burst with tonic stimulation in subjects already receiving SCS. At 4 IRB-approved sites, 22 subjects previously implanted with an SCS device for intractable, chronic pain gave informed consent and received burst stimulation for 14 days. Subjects reported average daily Visual Analog Scale (VAS) for overall, trunk, and limb pain using tonic stimulation and after 7 and 14 days of burst stimulation. Thoughts about pain were assessed using the Pain Catastrophizing Scale. Areas of paresthesia were assessed during tonic and burst stimulation using body maps. Assessment of patient satisfaction and preferred stimulation occurred after 14 days of burst. Average daily overall VAS reduced 46% from a mean of 53.5 (±20.2) mm during tonic SCS to 28.5 (±18.1) mm during burst (p pain relief was the most common reason cited for preference. A majority of subjects reported improved pain relief using burst compared with tonic stimulation. Most subjects experienced less paresthesia during burst and preferred burst citing better pain relief. © 2015 The Authors.

Purpose: To test the hypothesis that increasing the nerve length within the treatment volume for trigeminal neuralgia radiosurgery would improve pain relief. Methods and Materials: Eighty-seven patients with typical trigeminal neuralgia were randomized to undergo retrogasserian gamma knife radiosurgery (75 Gy maximal dose with 4-mm diameter collimators) using either one (n=44) or two (n=43) isocenters. The median follow-up was 26 months (range 1-36). Results: Pain relief was complete in 57 patients (45 without medication and 12 with low-dose medication), partial in 15, and minimal in another 15 patients. The actuarial rate of obtaining complete pain relief (with or without medication) was 67.7%±5.1%. The pain relief was identical for one- and two-isocenter radiosurgery. Pain relapsed in 30 of 72 responding patients. Facial numbness and mild and severe paresthesias developed in 8, 5, and 1 two-isocenter patients vs. 3, 4, and 0 one-isocenter patients, respectively (p=0.23). Improved pain relief correlated with younger age (p=0.025) and fewer prior procedures (p=0.039) and complications (numbness or paresthesias) correlated with the nerve length irradiated (p=0.018). Conclusions: Increasing the treatment volume to include a longer nerve length for trigeminal neuralgia radiosurgery does not significantly improve pain relief but may increase complications

Subacute combined degeneration of the spinal cord (vitamin B 12 -deficient myelopathy) is a neurologic disorder manifesting progressive symptoms of paresthesia and spastic paralysis. As shown by pathology, it initially involves the posterior columns of the thoracic cord. We present a case of vitamin B 12 deficiency with preferential posterior column involvement of the thoracic cord in a child. Theoretically, this should be the earliest, most reversible stage of the disease, making recognition of this MRI pattern of critical importance. (orig.)

Endoscope-assisted transoral open reduction and internal fixation (EAORIF) for mandibular condyle fractures has recently become popular because it is minimally invasive, provides excellent visibility without a large incision, and reduces surgical scarring and the risk of facial nerve injury. This report describes a retrospective clinical study that compared certain clinical parameters, including postoperative function, between the retromandibular (RM) approach and EAORIF. Fifteen patients were treated by the RM approach, whereas 15 underwent EAORIF between July 2006 and September 2011 at Kyushu Dental College, Japan. Clinical indices comprised fracture line, fracture type, number of plates used, surgical duration, bleeding amount, and functional items, including maximum interincisal opening, mandibular deviation on the opening pathway, malocclusion, facial paresthesia, and temporomandibular joint pain and clicking. The areas subjected to either approach included lower neck and subcondyle. The RM approach was used for mandibular condyle fractures with dislocation of a small bone segment. Both groups used 2 plates in all cases. Surgical duration, maximum interincisal opening, mandibular deviation, occlusion, and temporomandibular joint function at 6 months after surgery were comparable between groups. The average bleeding amount in the EAORIF group was greater than in the RM group. One patient from the RM group developed facial paresthesia that persisted for 6 months after surgery. It was concluded that surgical treatment was suitable for fractures of the lower neck and subcondylar. Both procedures showed good results in the functional items of this study.

Spinal cord stimulation (SCS) has been in clinical use for nearly four decades. In earliest observations, researchers found a significant increase in pain threshold during SCS therapy without changes associated with touch, position, and vibration sensation. Subsequent studies yielded diverse results regarding how SCS impacts pain and other sensory thresholds. This pilot study uses quantitative sensory testing (QST) to objectively quantify the impact of SCS on warm sensation, heat pain threshold, and heat pain tolerance. Nineteen subjects with an indwelling SCS device for chronic pain were subjected to QST with heat stimuli. QST was performed on an area of pain covered with SCS-induced paresthesia and an area without pain and without paresthesia, while the SCS was turned off and on. The temperature at which the patient detected warm sensation, heat pain, and maximal tolerable heat pain was used to define the thresholds. We found that all three parameters, the detection of warm sensation, heat pain threshold, and heat pain tolerance, were increased during the period when SCS was on compared with when it was off. This increase was observed in both painful and non-painful sites. The observed pain relief during SCS therapy seems to be related to its impact on increased sensory threshold as detected in this study. The increased sensory threshold on areas without pain and without the presence of SCS coverage may indicate a central (spinal and/or supra-spinal) influence from SCS. © 2015 International Neuromodulation Society.

Gamma knife surgery (GKS) has been employed for treating intractable pain such as trigeminal neuralgia (TN) and pain relief has been gained from the treatment, however, little is understood about the side effects of other sensitivities induced from GKS. We assessed ten patients (four men and six women; mean age 67 years) with TN who were investigated by questionnaire for symptoms and visual analog scale (VAS) of pain, and their threshold of touch sensation was examined using Semmes-Weinstein monofilaments, cold sensation and allodynia before and after GKS. MR and CT images were obtained after a Leksell head frame was applied to the head parallel to the trigeminal nerve. These images were uploaded to a computer system and retro-Gasserian area planned the target was correctly marked on the images of a computer in which gamma planning software was installed. All patients were irradiated with a maximum dose of 90 Gy at retro-Gasserian using a 4 mm collimator. The mean±standard deviation (SD) of VAS of pain was 8.5±1.3 and 8 patients had facial paresthesia before GKS. All patients experienced a significant reduction in pain without side effects such as effect on the peripheral nerves without 6 month after GKS. Allodynia, facial paresthesia or cold sensation numbness occurred in the patients before GKS disappeared according to complete pain relief. These results suggest that GKS is a safe and effective treatment for TN. (author)

A 30-year-old male with T-cell acute lymphoblastic leukemia presented with facial numbness. Neurological examination revealed paresthesia of the left trigeminal nerve. Cerebrospinal fluid (CSF) cytology showed no atypical cells. Gadolinium-enhanced magnetic resonance (MR) imaging demonstrated enlargement and enhancement of intracranial portions of the left trigeminal nerve. The abnormal MR imaging findings almost completely resolved after the chemotherapy. Gadolinium-enhanced MR imaging is not only a useful procedure for the early diagnosis of cranial nerve invasion by leukemia but it might be helpful to follow the changes after the treatment.

Full Text Available Venomous animals are those that, by means of a hunting and defense mechanism, are able to inject their prey with a toxic substance produced in their bodies, directly from specialized glands (e.g., tooth, sting, spur through which the poison passes. Millipedes are poisonous animals; they can be harmful to humans, and their effects usually manifest as erythematous, purpuric, and cyanotic lesions; local pain; and paresthesia. Here, we report a case of skin contact with a millipede for 6h resulting in skin lesions similar to blue toe syndrome.

Tumors can metastasize to the oral cavity and affect the jaws, soft tissue and salivary glands. Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Because of their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. The purpose of this report is to present a rare case of a metastatic breast carcinoma mimicking a periodontal abscess in the mandible. A 55-year-old Caucasian woman was referred to our clinic for evaluation of bisphosphonate-induced jaw osteonecrosis. She had undergone modified radical mastectomy with axillary lymph node dissection for invasive ductal carcinoma of the left breast. Her clinical examination showed diffuse swelling and a periodontal pocket of 6 mm exhibiting suppuration in the posterior right mandible. Moreover, paresthesia of the lower right lip and chin was noted. There were no significant radiographic findings other than alveolar bone loss due to her periodontal disease. Although the lesion resembled a periodontal abscess, metastatic carcinoma of the breast was suspected on the basis of the patient's medical history. The area was biopsied, and histological analysis confirmed the final diagnosis of metastatic breast carcinoma. The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease. This case highlights the importance of the value of a detailed medical history and thorough clinical examination for the early detection of metastatic tumors in the oral cavity.

Sleep disturbances in Guillain-Barre Syndrome (GBS), though common, have not received focused attention. To study frequency and nature of sleep disturbances in patients with GBS, using validated questionnaires, and analyze the contributing factors. This prospective study included 60 patients fulfilling National Institute of Neurological and Communicative Diseases and Stroke (NINCDS) criteria for GBS (mean age: 32.7 ± 12.9 years; median: 30 years; M:F = 46:14), evaluated from 2008 to 2010. Data regarding sleep were collected on 10 consecutive days following admission using Richard Campbell Sleep score, St Mary's Hospital Sleep Questionnaire, and Pittsburgh Sleep Quality Index (PSQI) and correlated with various possible contributing factors like pain, paresthesia, anxiety, depression, autonomic dysfunctions, severity of disease, and therapeutic interventions among others. Qualitative and quantitative sleep disturbances were rather frequent and involved over 50% patients: abnormal PSQI - 13.3%, abnormal score on Richard scale - 51.6%, abnormal sleep onset latency - 35%, sleep fragmentation - 40%, and reduced sleep duration - 46.6%. The symptoms were severe during the first week of hospitalization and reduced thereafter. Sleep disturbances as scored on Richard scale significantly correlated with anxiety, pain, paresthesia, and severity of immobility (P < 0.05) but not with depression and use of analgesics or antineuritic drugs. This study first of its kind suggests that sleep disturbance in GBS is frequent, multi-factorial, often disturbing, and varies during the course of illness. Routine enquiry into the sleep disturbances and timely intervention may reduce morbidity and improve their quality of life. © 2012 John Wiley & Sons A/S.

According to data from the National Oceanic and Atmospheric Administration,in the years from 1959 to 1994, lightning was responsible for more than 3000 deaths and nearly 10,000 casualties. The most important characteristic features of lightning injuries are multisystem involvement and widely variable severity. Lightning strikes are primarily a neurologic injury that affects all 3 components of the nervous system: central, autonomic,and peripheral. Neurologic complications of lightning strikes vary from transient benign symptoms to permanent disability. Many patients experience a temporary paralysis called keraunoparalysis. Here we reported a 22-year-old mountaineer man with complaining of left sided hemiparesis after being hit by a lightning strike in the mountain 3 hours ago. There was no loss of consciousness at hitting time. On arrival the patient was alert, awake and hemodynamically stable. In neurologic examination cranial nerves were intact, left sided upper and lower extremity muscle force was I/V with a combination of complete sensory loss, and right-sided muscle force and sensory examination were normal. There is not any evidence of significant vascular impairment in the affected extremities. Brain MRI and CT scan and cervical MRI were normal. During 2 days of admission, with intravenous hydration, heparin 5000 unit SC q12hr and physical therapy of the affected limbs, motor and sensory function improved and was normal except mild paresthesia. He was discharged 1 day later for outpatient follow up while vitamin B1 100mg orally was prescribed.Paresthesia improved after 3 days without further sequels.

Case Report. Stroke is the most common cause of long-term disability. Dysesthesia, an unpleasant sensory disturbance, is common following thalamic stroke and evidence-based interventions for this impairment are limited. The purpose of this case report was to describe a decrease in dysesthesia following manual therapy intervention in a patient with history of right lacunar thalamic stroke. A 66-year-old female presented with tingling and dysesthesia in left hemisensory distribution including left trunk and upper/lower extremities, limiting function. Decreased left shoulder active range of motion, positive sensory symptoms but no sensory loss in light touch was found. She denied pain and moderate shoulder muscular weakness was demonstrated. Laterality testing revealed right/left limb discrimination deficits and neglect-like symptoms were reported. Passive accessory joint motion assessment of glenohumeral and thoracic spine revealed hypomobility and provoked dysesthesia. Interventions included passive oscillatory joint mobilization of glenohumeral joint, thoracic spine, ribs and shoulder strengthening. After six sessions, shoulder function, active range of motion, strength improved and dysesthesia decreased. Global Rating of Change Scale was +5 and QuickDASH score decreased from 45% to 22% disability. Laterality testing was unchanged. Manual therapy may be a beneficial intervention in management of thalamic stroke-related dysesthesia. Implications for Rehabilitation While pain is common following thalamic stroke, patients may present with chronic paresthesia or dysesthesia, often in a hemisensory distribution. Passive movement may promote inhibition of hyperexcitable cortical pathways, which may diminish aberrant sensations. Passive oscillatory manual therapy may be an effective way to treat sensory disturbances such as paresthesias or dysesthesia.

  In able-bodied participants, it is possible to induce a sense of perceptual embodiment in an artificial hand using a visual-tactile illusion. In amputee patients, electrical stimulation of sensory afferents using transcutaneous electrical nerve stimulation (TENS) has been shown to generate somatic sensations in an amputee's phantom limb(s). However, the effects of TENS on the perceptual embodiment of an artificial limb are not known. Our objective was to investigate the effects of TENS on the perceptual embodiment of an artificial limb in fully intact able-bodied participants.   We used a modified version of the rubber hand illusion presented to 30 able-bodied participants (16 women, 14 men) to convey TENS paresthesia to an artificial hand. TENS electrodes were located over superficial radial nerve on the lateral aspect of the right forearm (1 cm proximal to the wrist), which was hidden from view. TENS intensity was increased to a strong non-painful TENS sensation (electrical paresthesia) was felt beneath the electrodes and projecting into the fingers of the hand. The electrical characteristics of TENS were asymmetric biphasic electrical pulsed waves, continuous pulse pattern, 120 Hz pulse frequency (rate), and 80 µs pulse duration (width).   Participants reported significantly higher intensities of the rubber hand illusion during the two TENS conditions (mean = 5.8, standard deviation = 1.9) compared with the two non-TENS conditions (mean = 4.9, standard deviation = 1.7), p embodiment of an artificial hand. Further exploratory studies involving an amputee population are warranted. © 2011 International Neuromodulation Society.

To describe outcomes after surgical management of pediatric elbow dislocation with incarceration of the medial epicondyle. We conducted a retrospective case review of 11 consecutive children and adolescents with an incarcerated medial epicondyle fracture after elbow dislocation. All patients underwent open reduction internal fixation using a similar technique. We characterized outcomes at final follow-up. Average follow-up was 14 months (range, 4-56 mo). All patients had clinical and radiographic signs of healing at final follow-up. There was no radiographic evidence of loss of reduction at intervals or at final follow-up. There were no cases of residual deformity or valgus instability. Average final arc of elbow motion was 4° to 140°. All patients had forearm rotation from 90° supination to 90° pronation. Average Mayo elbow score was 99.5. Four of 11 patients had ulnar nerve symptoms postoperatively and 1 required a second operation for ulnar nerve symptoms. In addition, 1 required a second operation for flexion contracture release with excision of heterotopic ossification. Three patients had ulnar nerve symptoms at final follow-up. Two of these had mild paresthesia only and 1 had both mild paresthesia and weakness. Our results suggest that open reduction internal fixation of incarcerated medial epicondyle fractures after elbow dislocation leads to satisfactory motion and function; however, the injury carries a high risk for complications, particularly ulnar neuropathy.

Luiz Eduardo Imbelloni

Full Text Available CONTEXT AND OBJECTIVES: In major orthopedic surgery of the lower limbs, continuous spinal anesthesia (CSA and combined spinal epidural anesthesia (CSE are safe and reliable anesthesia methods. In this prospective randomized clinical study, the blockading properties and side effects of CSA were compared with single interspace CSE, among patients scheduled for major hip or knee surgery. DESIGN AND SETTING: Prospective clinical study conducted at the Institute for Regional Anesthesia, Hospital de Base, São José do Rio Preto. METHODS: 240 patients scheduled for hip arthroplasty, knee arthroplasty or femoral fracture treatment were randomly assigned to receive either CSA or CSE. Blockades were performed in the lateral position at the L3-L4 interspace. Puncture success, technical difficulties, paresthesia, highest level of sensory and motor blockade, need for complementary doses of local anesthetic, degree of technical difficulties, cardiocirculatory changes and postdural puncture headache (PDPH were recorded. At the end of the surgery, the catheter was removed and cerebrospinal fluid leakage was evaluated. RESULTS: Seven patients were excluded (three CSA and four CSE. There was significantly lower incidence of paresthesia in the CSE group. The resultant sensory blockade level was significantly higher with CSE. Complete motor blockade occurred in 110 CSA patients and in 109 CSE patients. Arterial hypotension was observed significantly more often in the CSE group. PDPH was observed in two patients of each group. CONCLUSION: Our results suggest that both CSA and CSE provided good surgical conditions with low incidence of complications. The sensory blockade level and hemodynamic changes were lower with CSA.

A 62-year-old man was referred to us after unsuccessful treatment of bilateral weakness in his upper and lower extremities with paresthesia in both lower extremities. Computed tomography (CT) revealed soft tissue masses in the left kidney along the capsule and paraaortic region that were of relatively low attenuation with accompanying granular calcifications. Pathological diagnosis of the biopsy specimen was extramedullary plasmacytoma accompanied by extramedullary hematopoiesis and amyloid deposition. Although the CT findings correlated well with the pathological results, the case was extremely atypical for extramedullary plasmacytoma in respect to location and the accompaniment with extramedullary hematopoiesis.

This paper reports eighteen patients with spondylolysis evaluated with sagittal MR imaging to correlate the factors and degree of faoraminal stenosis at the level of the lysis with clinical findings. Fifteen presented with low back pain, eight with radiculopathy and one with paresthesia in the lower limbs, and two were asymptomatic. The degree of foraminal stenosis, quantified in three grades, was not correlated with the onset of radiculopathy. Three foraminal herniations were responsible for radiculopathy. Presence of isthmic bony tip and fibrocartilage buildup were not correlated with symptoms. Foraminal compression can be demonstrated by MR imaging, but without clinical correlations

Abstract Objective To present a case of a pregnant patient with meralgia paresthetica who improved using manual therapy and exercise procedures. Clinical Features A 22-year-old patient in the sixteenth week of pregnancy had low back pain, bilateral anterolateral thigh paresthesia and groin pain for a duration of 1 month. She had no motor deficits in either lower extremity and her reflexes were intact. As a standard clinic procedure, a battery of functional tests were performed including: active straight leg raise, long dorsal ligament test, and the pelvic pain provocation procedure. Based on her clinical history and physical responses to the aforementioned functional tests, the diagnosis of meralgia paresthetica was deduced. Intervention and Outcome Treatment was provided at 6 visits over a 6-week period where the patient underwent evaluation, manual intervention, and exercise prescription. Active Release Technique (ART) was performed to the restricted right sacroiliac (SIJ) complex and quadratus lumborum muscles. ART and post-isometric relaxation were applied to the illiopsoas muscles. The home exercise program consisted of pelvic/low back mobility, stabilization and relaxation exercises. After 6 treatments, the patient reported complete resolution of low back pain and left lower extremity symptoms and a 90% improvement in the right thigh symptoms. At her one-year follow-up, the patient reported no further complications and the absence of pain. Conclusions Manual therapy and exercises may serve as an effective treatment protocol for pregnant patients experiencing low back pain complicated by paresthesia. Because these conservative procedures offer a low-risk intervention, additional clinical studies are warranted to further study this treatment. PMID:19674679

Although ciguatera fish poisoning (CFP) is the most common seafood intoxication worldwide, its burden has been difficult to establish because there are no biomarkers to diagnose human exposure. We explored the incidence of CFP, percentage of CFP case-patients with laboratory-confirmed ciguatoxic meal remnants, cost of CFP illness, and potential risk factors for CFP. During 2005 and again during 2006, we conducted a census of all occupied households on the island of Culebra, Puerto Rico, where locally caught fish are a staple food. We defined CFP case-patients as persons with gastrointestinal symptoms (abdominal pain, vomiting, diarrhea, or nausea) and neurological symptoms (extremity paresthesia, arthralgia, myalgia, malaise, pruritus, headache, dizziness, metallic taste, visual disturbance, circumoral paresthesia, temperature reversal, or toothache) or systemic symptoms (e.g., bradycardia) within 72 hr of eating fish during the previous year. Participants were asked to save fish remnants eaten by case-patients for ciguatoxin analysis at the Food and Drug Administration laboratory in Dauphin Island, Alabama (USA). We surveyed 340 households during 2005 and 335 households during 2006. The estimated annual incidence of possible CFP was 4.0 per 1,000 person-years, and that of probable CFP was 7.5 per 1,000 person-years. One of three fish samples submitted by probable case-patients was positive for ciguatoxins. None of the case-patients required respiratory support. Households that typically consumed barracuda were more likely to report CFP (p = 0.02). Our estimates, which are consistent with previous studies using similar case findings, contribute to the overall information available to support public health decision making about CFP prevention.

Full Text Available Exacerbation of the immune response against Mycobacterium leprae can lead to neuritis, which is commonly treated via immunosuppression with corticosteroids. Early neurolysis may be performed concurrently, especially in young patients with a risk of functional sequelae. We report the case of a young patient experienced intense pain in the left elbow one year after the treatment of tuberculoid-tuberculoid leprosy. The pain was associated with paresthesias in the ulnar edge and left ulnar claw. After evaluation, the diagnosis was changed to borderline tuberculoid leprosy accompanied with neuritis of the left ulnar nerve. Early neurolysis resulted in rapid reduction of the pain and recovery of motor function.

Wasserman, T.H.; Nelson, J.S.; VonGerichten, D.

1984-01-01

The dose limiting toxicity of the nitroimidazole radiosensitizers is peripherial neuropathy. Improved pharmacology of newer drugs has eliminated the encephalopathy. Peripheral neuropathies are predominently mild to moderate paresthesias of both hands and feet. Subjective changes occur with or without minimal objective changes on neurologic exam. All of the neuropathies occurred within 30 days of the last drug dose and are of varible duration. Sural nerve biopsies from patients indicate progressive axonal degeneration affecting both large and small caliber myelinated fibers. Axonal damage appears to be more severe in the distal portion of the nerves. More data are needed for correlation of clinical and pathological changes

Peripheral neuropathy and nerve compression syndromes lead to substantial morbidity following burn injury. Patients present with pain, paresthesias, or weakness along a specific nerve distribution or experience generalized peripheral neuropathy. The symptoms manifest at various times from within one week of hospitalization to many months after wound closure. Peripheral neuropathy may be caused by vascular occlusion of vasa nervorum, inflammation, neurotoxin production leading to apoptosis, and direct destruction of nerves from the burn injury. This article discusses the natural history, diagnosis, current treatments, and future directions for potential interventions for peripheral neuropathy and nerve compression syndromes related to burn injury.

Full Text Available Gitelman’s syndrome is a rare autosomal-recessive tubular disorder characterized by hypomagnesemia and hypocalciuria associated to hypokalemia. The clinical spectrum is wide and usually characterized by chronic fatigue, cramps, muscle weakness and paresthesiae. We describe a case of a 43 year-old male patient with early onset of knee arthritis and no other symptoms. Ultrasound revealed diffuse and confluent hyperechoic deposits in cartilage, fibrocartilage of the menisci and synovium and calcium pyrophosphate crystals were observed in the synovial fluid of the knee. The concomitant presence of hypomagnesemia, hypocalciuria and hypokalemia made clear the diagnosis of Gitelman’s syndrome associated with chondrocalcinosis.

The identification and actual location of MF are important in order to avoid sensory dysfunction or paresthesia due to mental nerve injury. In the literature there are some rare reports on the anatomical variations of the MF such as its location or presence of accessory foramina. The present report describes the absence of mental foramina on the left side of the mandible, as detected by cone-beam computed tomography before impacted tooth removal and observed directly during surgery.

Full Text Available Colchicine is a relatively safe medication that is widely used for both prevention and treatment of gout attack. However, serious adverse events, including myoneuropathy and multiorgan failure, have been reported. We report a case of colchicine-induced myoneuropathy in a female kidney transplant recipient who had been taking cyclosporine. She developed gastrointestinal discomfort and paresthesia 5 days after the initiation of colchicine. She showed signs of myoneuropathy, and hepatic and renal injury. Colchicine toxicity was suspected, and colchicine was discontinued. Her symptoms and laboratory findings improved gradually. Literature was reviewed for previous reports of colchicine-induced myoneuropathy in solid organ transplant recipients.

Full Text Available Acute intermittent porphyria (AIP and ichthyosis vulgaris both are autosomal dominant disorders with incomplete penetrance caused by the deficiency of porphobilinogen deaminase enzyme and filaggrin protein, respectively. We report a rare case of a 9-year-old boy having two genetic diseases with an unclear association. An acute attack of AIP is characterized by gastrointestinal symptoms and neuropsychiatric manifestations. Although rare in the first decade of life, the presence of reddish urine with a typical presentation such as abdominal pain, hypertension, seizure, and paresthesias lead us to the diagnosis of AIP. The precipitating factor in the present case was prolonged fasting in Ramadan.

To assess outcomes after endovenous laser ablation (EVLA) of the small saphenous vein (SSV). Retrospective review was performed of all consecutive EVLA procedures performed over a 39-month period at three neighboring vein practices for symptomatic, duplex ultrasound-proven incompetence of the SSV. EVLA was performed under ultrasound guidance with an 810- or 980-nm diode laser in continuous mode using the pullback method while sparing the deep, most cephalad segment of the SSV near the saphenopopliteal junction. Follow-up after EVLA included patient symptoms, physical examination, and duplex ultrasound. Pretreatment variables were similar across all three practices. EVLA was performed to treat 67 incompetent SSVs in 63 patients (86% women; mean age and 95% confidence interval, 50 ± 3 years; range, 20-82 years). Average energy delivered was 92 J/cm. Immediate technical success and occlusion of the treated vein at 1-2 weeks was 100%. Imaging follow-up length was 243 ± 65 days (range, 3-893 days). Clinical follow-up (243 ± 66 days) showed symptomatic improvement in 66 (99%) of 67 patients; one patient had recanalization with recurrent reflux by ultrasound (2%). Complications included one case of paresthesias lasting beyond 1 month of follow-up (2%) and three cases of superficial phlebitis (4%), but no deep vein thrombosis, skin burns, or other complications. Although ablation involved only the superficial portion of the SSV and spared its deep segment in the popliteal fossa, SSV occlusion typically extended up to the saphenopopliteal junction or to a gastrocnemial collateral, without popliteal vein involvement. EVLA of the SSV is safe and effective when the saphenopopliteal junction and popliteal fossa are avoided. This approach may help reduce the risk of paresthesias or other complications while maintaining low recanalization rates.

To compare the functional outcome of successful microsurgical replantation versus amputation closure for single fingertip amputations. Forty-six fingertip amputations in 46 patients (23 were replanted successfully, 23 had amputation closure) were included in this study. Thumb amputations were excluded. Grip strength and active range of motion of the proximal interphalangeal joint were evaluated. The patients were questioned about their symptoms of pain, paresthesia, and cold intolerance. The Disabilities of the Arm, Shoulder, and Hand questionnaire was given and the disability/symptom score was evaluated. Patients' satisfaction with the surgical result was assessed. Time spent in the hospital and time off from work were reviewed. Active range of motion of the proximal interphalangeal joint was greater in the successful replantation group. Although the existence of paresthesia and cold intolerance were not statistically different between the 2 groups, pain in the affected fingers was more frequent in the amputation closure group. The average Disabilities of the Arm, Shoulder, and Hand score of the successful replantation group was statistically better. All patients in the successful replantation group were highly or fairly satisfied with the surgical results, whereas 14 patients in the amputation closure group were highly or fairly satisfied. The time spent in the hospital and the time off from work for the successful replantation group were longer. Successful replantation of single fingertip amputations can result in minimal pain, better functional outcome, better appearance, and higher patient satisfaction. We recommend attempting fingertip replantation not only to obtain the best appearance but also to gain better functional outcome. If the patient requests the simple surgery and earlier return to work amputation closure is an accepted method despite the disadvantage of digital shortening and the risk for a painful stump.

Full Text Available Chronic myelogenous leukemia (CML is a myeloproliferative disorder characterized by increased proliferation of predominantly myeloid cells in the bone marrow and their accumulation in the peripheral blood. Nowadays, drugs known as tyrosine kinase inhibitors (TKIs are the standard treatment for CML. Since TKIs specifically target BCR-ABL, the activated tyrosine kinase fusion protein, they are expected to cause less hematological and nonhematological side effects than medications used before. We report a case of a 61-year-old patient treated with the second-generation TKI, nilotinib, that presented with very common side effects (skin rash, myalgia, and paresthesia, and also with rare, but severe hypocalcemia and potentially dangerous and fatal QTc elongation.

A middle aged male presented with non-tender cystic swelling over left distal forearm since 1 year. No other cutaneous abnormality could be found except mild paresthesia of the overlying skin and equivocal thickening of the ipsilateral ulnar nerve. Routine investigation was within normal limits. Detailed workup of the patient including MRI of the lesion suggested the diagnosis as tenosynovitis with a soft tissue mass. Fine needle aspiration cytology from the cyst showed foamy macrophages and acid fast bacilli; while PCR of the aspirate confirmed the etiological agent as M. leprae. We, thus, report a unique case of isolated tenosynovitis as a sole manifestation of pure neural leprosy which is extremely rare in world literature. PMID:25814736

Hemangiopericytoma is an uncommon mesenchymal neoplasm that rarely affects the spinal canal. Primary malignant hemangiopericytoma of the spinal column is extremely rare. We report on a case of primary epidural malignant hemangiopericytoma of the thoracic spinal column that invaded vertebral bone and caused spinal cord compression in a 21-year-old man. The patient presented with progressive back pain over a four-month period that progressed to paraparesis, bilateral leg paresthesia and urinary incontinence. The surgical intervention involved laminectomy and subtotal resection of the tumor, with posterior vertebral fixation. Postoperative involved-field radiotherapy was administered. A marked neurological improvement was subsequently observed. We describe the clinical, radiological, and histological features of this tumor and review the literature.

A retromolar canal is an anatomical variation in the mandible. As it includes the neurovascular bundle, local anesthetic insufficiency can occur, and an injury of the retromolar canal during dental surgery in the mandible may result in excessive bleeding, paresthesia, and traumatic neuroma. Using imaging analysis software, we evaluated the cone-beam computed tomography (CT) images of two Korean patients who presented with retromolar canals. Retromolar canals were detectable on the sagittal and cross-sectional images of cone-beam CT, but not on the panoramic radiographs of the patients. Therefore, the clinician should pay particular attention to the identification of retromolar canals by preoperative radiographic examination, and additional cone beam CT scanning would be recommended.

The most frequent malignant salivary gland tumours are the mucoepidermoid tumour, adenoid cystic carcinoma and adenocarcinoma. The major salivary glands and the minor glands of the mouth and upper respiratory tract may potentially develop any of these malignant lesions. Malignant lesions most frequently present as a palpable mass and tend to enlarge more rapidly than benign neoplasms. Pain, paresthesia, muscle paralysis and fixation to surrounding tissue are all ominous signs and symptoms. The only reliable means of differential diagnosis of these lesions is biopsy and histologic analysis. Therapy involves surgery or a combination of surgery and radiation therapy. The ultimate prognosis is governed by the intrinsic biologic behaviour of the neoplasms, the extent of disease and adequate clinical therapy

2014-10-01

Malignancies in the head and neck region are difficult to diagnose because of their deep location and presence of symptoms mimicking those of temporomandibular disorders or other orofacial pain disorders. A 75-year-old woman reported experiencing right-sided jaw pain, temporal discomfort and paresthesia. She had undergone conservative therapy for temporomandibular joint disorder, which was unsuccessful. A magnetic resonance image of the midface revealed a mass on the base of the tongue along with possible metastatic lesions to the brain. Further investigation of the lesions revealed them to be metastatic melanoma. Patients with atypical symptoms of facial pain, including neurological signs, should undergo further investigation with advanced imaging to determine the source of the symptoms, which could include neoplasms.

Anti-MAG neuropathy is a very rare form of acquired polyneuropathy associated with IgM monoclonal gammopathy of undetermined significance (MGUS). We conducted a retrospective review of 194 consecutive MGUS patients seen at the Penn State Hershey Cancer Institute. We identified six patients among 37 (16 %) with IgM MGUS with anti-MAG neuropathy. Interestingly, an additional patient had anti-MAG neuropathy without MGUS. Common clinical manifestations were numbness and paresthesias of the extremities and gait imbalance. All four patients treated with rituximab and none of the three untreated ones had a subjective improvement of their symptoms. We conclude that all patients with IgM MGUS and neuropathy should be screened for anti-MAG antibodies and, if positive, they should be offered treatment with rituximab.

Full Text Available Eosinophilic meningitis or encephalitis is a rare disorder and is most commonly caused by Angiostrongylus cantonensis. Humans are accidentally infected when they ingest raw snails or vegetables contaminated with the parasite larvae. Because of the improvement in sanitary food handling practices, the occurrence of A. cantonensis eosinophilic meningitis has been decreasing in Taiwan in recent decades. The common symptoms and signs of eosinophilic meningitis are severe headache, neck stiffness, paresthesia, vomiting, nausea, and fever. Acute urinary retention is a rare presentation. We report a case of A. cantonensis eosinophilic meningitis in an intellectually disabled patient who presented with acute urinary retention without any other meningeal signs. The patient received supportive treatment with corticosteroid therapy and was discharged and received urinary rehabilitation at home.

Full Text Available Lumbosacral plexopathies are of considerably less epidemiologic common prevalence than brachial plexus. The most common form of trauma resulting in lesions affecting the lumbosacral plexus is injuries to sacroiliac region. The symptoms which are caused by compressing lumbosacral plexus are sensory disturbance and weakness in an affected leg. The author reports a case of a 65-year-old male with a history of right acetabular fracture status post open reduction and internal fixation by plate and screw who complained weakness and numbness in the right leg. Four months later, he still had difficulty in walking and felt paresthesia at the right lateral thigh and entire of the right foot. His further investigation which was electrodiagnostic study was diagnosed as right lumbosacral plexopathies.

Full Text Available Lumbar spinal stenosis results from the progressive combined narrowing of the central spinal canal, the neurorecesses, and the neuroforaminal canals. In the absence of prior surgery, tumor, or infection, the spinal canal may become narrowed by bulging or protrusion of the intervertebral disc annulus, herniation of the nucleus pulposis posteriorly, thickening of the posterior longitudinal ligament, hypertrophy of the ligamentum flavum, epidural fat deposition, spondylosis of the intervertebral disc margins, or a combination of two or more of the above factors. Patients with spinal stenosis become symptomatic when pain, motor weakness, paresthesia, or other neurologic compromise causes distress. In one case, we administrated oriental medical treatment with acupuncture treatment and herb-medicine. Oriental medical treatment showed desirable effect on lumbar spinal stenosis.

Full Text Available At the present time the incidence of illicit drug use increases worldwide among young adults. Abuse of these substances is a rare cause of stroke in young adults. Cocaine, heroin, cannabis, and amphetamines use increase the risk of stroke. Cannabis sativa induce main effects by delta-9-hydrocannabinol. The main mechanism of marijuana-related stroke in young patients is vasospazm. The other possible mechanisms are systemic hypotension, impaired cerebral autoregulation, alteration of cerebral blood flow, cardioembolism due to atrial fibrillation. In this article a 25-year-old young male patient with paresia and paresthesia of right side who had chronic abuse of marijuana is reported. Clinicians must be alert about marijuana can be seriously harmful to cerebrovascular system in chronic use.

One of the most common oral surgical procedures is the extraction of the lower third molar (LTM). Postoperative complications such as paresthesia due to inferior alveolar nerve (IAN) injury are commonly observed in cases of horizontal and vertical impaction. The present report discusses a case of a vertically impacted LTM associated with a dentigerous cyst. An intimate contact between the LTM roots and the mandibular canal was observed on a panoramic radiograph and confirmed with cone-beam computed tomographic (CBCT) cross-sectional cuts. An orthodontic miniscrew was then used to extrude the LTM prior to its surgical removal in order to avoid the risk of inferior alveolar nerve injury. CBCT imaging follow-up confirmed the success of the LTM orthodontic extrusion.

Reversible brachial plexopathy has occurred in very low incidence in patients with breast carcinoma treated definitively with radiation therapy. Of 565 patients treated between January 1968 and December 1979 with moderate doses of supervoltage radiation therapy (average axillary dose of 5000 rad in 5 weeks), eight patients (1.4%) developed the characteristic symptoms at a median time of 4.5 months after radiation therapy. This syndrome consists of paresthesias in all patients, with weakness and pain less commonly seen. The symptom complex differs from other previously described brachial plexus syndromes, including paralytic brachial neuritis, radiation-induced injury, and carcinoma. A possible relationship to adjuvant chemotherapy exists, though the etiology is not well-understood. The cases described demonstrate temporal clustering. Resolution is always seen

Full Text Available Background: The concept of femoral neck preservation in total hip replacement (THR was introduced in 1993. It is postulated that retaining cortical bone of the femoral neck offers triplanar stability, uniform stress distribution, and accommodates physiological anteversion. However, data on safety, efficacy and learning curve are lacking. Materials and Methods: We prospectively assessed all patients who were operated for a THR with a short neck preserving stem (MiniHip between 2012 and 2014. The safety and learning curve were assessed by recording operative time; stem size; and adverse events including periprosthetic fracture; paresthesia; and limb length discrepancy (LLD. The cohort was divided into equal groups to assess the learning curve effect, and the cumulative sums (CUSUM test was performed to monitor intraoperative neck fractures. For assessment of efficacy, Oxford Hip Score (OHS and Short Form-36 (SF-36 scores were compared preoperatively and postoperatively. Results: 138 patients with median age 62 years (range 35–82 years were included with a median followup of 42 months (range 30–56 months. The minimum followup was 2.5 years. The OHS, SF-36 (physical and mental component scores improved by a mean score of 26, 28, and 27 points, respectively. All patients had LLD of <10 mm (1.9 mm ± 1.3. Adverse events included intraoperative neck fracture (n = 6, subsidence (n = 1, periprosthetic fracture (n = 1, paresthesia (n = 12, and trochanteric bursitis (n = 2. After early modification of the technique to use a smaller finishing broach, the CUSUM test demonstrated acceptable intraoperative neck fracture risk. The second surgery group had a reduced risk of intraoperative neck fracture (5/69 vs. 1/69 P = 0.2, reduced operative time (66 vs. 61 min, P = 0.06, and increased stem size (5 vs. 6, P = 0.09 although these differences were not statistically significant. Conclusions: The MiniHip stem is safe alternative to standard THR with good

Background: In this study, we present the previously unreported pain relief outcomes of 108 patients treated at Gamma Knife of Spokane for typical trigeminal neuralgia (TN) between 2002 and 2011. Methods: Pain relief outcomes were measured using the Barrow Neurological Institute (BNI) pain intensity scale. In addition, the effects gender, age at treatment, pain laterality, previous surgical treatment, repeat Gamma Knife radiosurgery (GKRS), and maximum radiosurgery dose have on patient pain relief outcomes were retrospectively analyzed. Statistical analysis was performed using Andersen 95% confidence intervals, approximate confidence intervals for log hazard ratios, and multivariate Cox proportional hazard models. Results: All 108 patients included in this study were grouped into BNI class IV or V prior to GKRS. The median clinical follow-up time was determined to be 15 months. Following the first GKRS procedure, 71% of patients were grouped into BNI class I-IIIb (I = 31%; II = 3%; IIIa = 19%; IIIb = 18%) and the median duration of pain relief for those patients was determined to be 11.8 months. New facial numbness was reported in 19% of patients and new facial paresthesias were reported in 7% of patients after the first GKRS procedure. A total of 19 repeat procedures were performed on the 108 patients included in this study. Following the second GKRS procedure, 73% of patients were grouped into BNI class I-IIIb (I = 44%; II = 6%; IIIa = 17%, IIIb = 6%) and the median duration of pain relief for those patients was determined to be 4.9 months. For repeat procedures, new facial numbness was reported in 22% of patients and new facial paresthesias were reported in 6% of patients. Conclusions: GKRS is a safe and effective management approach for patients diagnosed with typical TN. However, further studies and supporting research is needed on the effects previous surgical treatment, number of radiosurgery procedures, and maximum radiosurgery dose have on GKRS clinical

Experienced neurosurgeons at eight spinal cord stimulation centers in the United States, Canada, and Europe participated in a study from 1997 to 2000 investigating the safety, performance, and efficacy of a Transverse Tripolar Stimulation (TTS) system invented at the University of Twente, the Netherlands. This device was proposed to improve the ability of spinal cord stimulation to adequately overlap paresthesia to perceived areas of pain. Fifty-six patients with chronic, intractable neuropathic pain of the trunk and/or limbs more than three months' duration (average 105 months) were enrolled with follow-up periods at 4, 12, 26, and 52 weeks. All patients had a new paddle-type lead implanted with four electrodes, three of them aligned in a row perpendicular to the cord. Fifteen of these patients did not undergo permanent implantation. Of the 41 patients internalized, 20 patients chose conventional programming using an implanted pulse generator to drive four electrodes, while 21 patients chose a tripole stimulation system, which used radiofrequency power and signal transmission and an implanted dual-channel receiver to drive three electrodes using simultaneous pulses of independently variable amplitude. On average, the visual analog scale scores dropped more for patients with TTS systems (32%) than for conventional polarity systems (16%). Conventional polarity systems were using higher frequencies on average, while usage range was similar. Most impressive was the well-controlled "steering" of the paresthesias according to the dermatomal topography of the dorsal columns when using the TTS-balanced pulse driver. The most common complication was lead migration. While the transverse stimulation system produced acceptable outcomes for overall pain relief, an analysis of individual pain patterns suggests that it behaves like spinal cord stimulation in general with the best control of extremity neuropathic pain. This transverse tripole lead and driving system introduced

Low-level laser has been widely used in Dentistry and many studies have focused on its application in oral surgeries. This study was conducted with the aim of searching for scientific evidence concerning the effectiveness of laser to reduce pain or paresthesia related to orthognathic surgery. An electronic search was performed in PubMed, Scopus, Science Direct, LILACS, SciELO, CENTRAL, Google Scholar, OpenGrey, and ClinicalTrials.gov, up to November 2016, with no restrictions on language or year of publication. Additionally, a hand search of the reference list of the selected studies was carried out. The PICOS strategy was used to define the eligibility criteria and only randomized clinical trials were selected. Out of 1,257 identified citations, three papers fulfilled the criteria and were included in the systematic review. The risk of bias was assessed according to the Cochrane Guidelines for Clinical Trials and results were exposed based on a descriptive analysis. One study showed that laser therapy was effective to reduce postoperative pain 24 hours (P=0.007) and 72 hours (P=0.007) after surgery. Other study revealed the positive effect of laser to improve neurosensory recovery 60 days after surgery, evaluated also by the two-point discrimination (P=0.005) and sensory (P=0.008) tests. The third study reported an improvement for general sensibility of 68.75% for laser group, compared with 21.43% for placebo (P=0.0095), six months after surgery. Individual studies suggested a positive effect of low-level laser therapy on reduction of postoperative pain and acceleration of improvement of paresthesia related to orthognathic surgery. However, due to the insufficient number and heterogeneity of studies, a meta-analysis evaluating the outcomes of interest was not performed, and a pragmatic recommendation about the use of laser therapy is not possible. This systematic review was conducted according to the statements of PRISMA and was registered at PROSPERO under the

Celiac disease is an immune-mediated disorder elicited by ingestion of gluten in genetically susceptible persons. This disorder is characterized by specific histological changes of the small intestine mucosa resulting in malabsorption. This case was written up as it was an unusual and dramatic presentation of celiac disease. We report the case of a 3-year-old Albanian girl who presented at our clinic with carpal spasms and hand paresthesia. A physical examination at admission revealed a relatively good general condition and body weight of 10.5 kg (10 percentile). Carpal spasms and paresthesias of her extremities were present. Neuromuscular irritability was demonstrated by positive Chvostek and Trousseau signs. Blood tests showed severe hypocalcemia with a total serum calcium of 1.2 mmol/L (normal range 2.12 to 2.55 mmol/L), ionized calcium of 0.87 (normal range 1.11 to 1.30 mmol/L), and 24-hour urine calcium excretion of 9.16 mmol (normal range female celiac disease was performed: antigliadin immunoglobulin A, anti-tissue transglutaminase, and anti-endomysial immunoglobulin A antibodies were positive. A duodenal biopsy revealed lymphocyte infiltration, crypt hyperplasia, and villous atrophy compatible with celiac disease grade IIIb according to the Marsh classification. Following the diagnosis of celiac disease, human leukocyte antigen typing was performed, giving a definite diagnosis of celiac disease. She was started on a gluten-free diet. Due to failure to follow a gluten-free diet, episodes of carpal spasms appeared again. Unfortunately, at the age of 7 years she presents with delayed psychophysical development. Although hypocalcemia is a common finding in celiac disease, hypocalcemic carpal spasm is a rare initial manifestation of the disease. Therefore, the possibility of celiac disease should be considered in patients with repeated carpal spasms that seem unduly difficult to treat. This should be evaluated even in the absence of gastrointestinal

Failed back surgery syndrome (FBSS) is a term embracing a constellation of conditions that describes persistent or recurring low back pain, with or without sciatica following one or more spine surgeries. It has been shown in animals that electrical stimulation of the high cervical C2 area can suppress pain stimuli derived from the L5-S1 dermatome. It is unknown whether C2 electrical stimulation in humans can be used to treat pain derived from the L5-S1 area, and a case is reported in which subcutaneous C2 is applied to treat FBSS. A patient presents to the neuromodulation clinic because of FBSS (after three lumbar diskectomies) and noninvasive neuromodulation is performed consisting of transcutaneous electrical nerve stimulation (TENS) at C2. The C2 TENS stimulation is successful in improving pain. It induces paresthesias in the C2 dermatome above a certain amplitude threshold, but does not generate paresthesias in the pain area. However, the patient becomes allergic to the skin-applied TENS electrodes and therefore a new treatment strategy is discussed with the patient. A subcutaneous C2 electrode is inserted under local anesthesia, and attached to an external pulse generator. Three stimulation designs are tested: a classical tonic stimulation, consisting of 40 Hz stimulation, a placebo, and a burst stimulation, consisting of 40 Hz burst mode, with five spikes delivered at 500 Hz at 1000 μsec pulse width and 1000 μsec interspike interval. The patient's stimulation results demonstrate that burst mode is superior to placebo and tonic mode, and she receives a fully implanted C2 electrode connected to an internal pulse generator via an extension wire. The burst design is capable of both suppressing the least and worst pain effectively, and she has remained almost pain-free for over three years. © 2012 International Neuromodulation Society.

Sonography and electrodiagnosis in carpal tunnel syndrome diagnosis, an analysis of the literature

International Nuclear Information System (INIS)

Seror, P.

2008-01-01

We present a review of the international literature concerning sonography for the diagnosis of carpal tunnel syndrome (CTS). Analysis of the results and comparison with electrodiagnostic data provide a sensible albeit personal view on the relevance of sonography and whether it competes or is complementary to electrodiagnosis (EDX). Although EDX is considered as the gold standard for CTS diagnosis, one author chose surgical results to define CTS. The normal and threshold mean values for sonography are particularly variable from one study to another. The standard deviation (S.D.), when compared to mean values, makes normal and abnormal data overlap considerably and produces many false negatives when the specificity is high, and many false positives when the sensitivity is high. In fact, sonography is non-interpretable in only 10 to 15% of the population, and it affirms the median nerve lesion at the wrist in 55% of cases when EDX does it in more than 90% with common tests. Further more the specificity of sonography leads to a false positive diagnosis in 1 case out of 5 versus 1 out of 40 with EDX. The main conclusion is that there is no competition but rather a complementarity between sonography and EDX: sonography is certainly an efficient imaging technique but cannot replace proper EDX performed for upper limb paresthesiae. Namely, sonography can answer only one out of the 8 questions a complete EDX answer: Are sonographic images compatible with a median nerve lesion at the wrist? The answer to this solely question can be obtain with a partial EDX using a single conduction test (motor or sensitive), then duration and cost will be comparable to sonography but will be both more sensitive and specific. Finally, one must kept in mind that the final aim of all examinations in CTS is to determine the cause(s) of upper limb paresthesiae, not simply if there is a median nerve lesion at wrist or not

Guillain-Barré syndrome is a rare occurrence in pregnant women. We describe the case of a 21-year old woman, seen at "Nuevo Hospital Civil de Guadalajara" with a term pregnancy, who presented with limbs weakness and paresthesias, drowsiness and malaise. Her vital signs were normal but she was quadriparetic, there was muscular atrophy in the extremities and deep tendon reflexes were decreased. Spinal fluid analysis revealed a protein of 71.2 mg/dl, glucosa 48 mg/dl and no white cells and both Gram stain and routine cultures were negative. EMG studies reported poliradiculoneuritis; a C-section was done, and both the mother and a newborn girl did very well. Guillain-Barré syndrome should be suspected in similar cases in order to offer prompt intervention.

Ciguatera fish poisoning: impact for the military health care provider.

Ciguatera toxin is a marine neurotoxin produced by microorganisms that becomes concentrated in predatory fish. Toxicity in humans results from the ingestion of contaminated fish harvested in tropical waters. Clinical manifestations of illness include the rapid onset of gastrointestinal symptoms and neurological abnormalities. Because of the rapid onset of symptoms and the potential for case clusters from a common source ingestion of contaminated fish, there is the potential that ciguatera poisoning may initially mimic illnesses caused by antipersonnel biological and chemical agents. We present data on an active duty soldier who presented to sick call for evaluation of new onset paresthesias and was diagnosed with ciguatera toxin poisoning. We also present a review of ciguatera poisoning literature with emphasis on the distinguishing features between ciguatoxin and other neurotoxins of military significance.

Telangiectasia is the dilation of dermal capillaries mainly due to hypertension and vein insufficiency. Treatments of choice for this condition are sclerotherapy with foam liquid or intradermal fiber optic laser energy delivery. The aim of this study was to assess the efficacy of a new therapeutic approach consisting in the use of polymerized hyaluronic acid mesotherapic injections following sclerotherapy in the areas of the skin affected by telangiectasia in patients without major vein insufficiency. A total of 20 women, aged between 19 and 64 years, affected by recurrent lower leg telangiectasia, were included in this study. Patients were preliminarily submitted to echo color Doppler sonography to rule out severe saphenofemoral valve and lower limb major vein insufficiency. All patients underwent 3 sessions a month of polidocanol 1% capillary injections for 2 months. This was followed by 0.1 ml cross-linked hyaluronic acid introduction in the polidocanol 1% needle track. A total of 50 mesotherapic injections (0.05 ml each) were performed on the skin surface where an ice pack was previously applied for 4 to 5 minutes. A follow-up visit was performed at 3 months. The results, based on photographic examination, were rated as follows: poor improvement (0%-50%), good improvement (51%-75%), and very good improvement (76%-100%). The side effects of the clinical procedure, in terms of pain, itching, paresthesia, ecchymosis, and relapse of telangiectasia over the treated skin surface, as well as a persisting pigmentation in the injection spots and induced benefits related to leg heaviness and comfort, were recorded. In total, 6 patients displayed a slight venous insufficiency, 3 patients displayed patent venous insufficiency, and 11 patients did not show any venous insufficiency. Before treatment, itching was present in 18 out of 20 patients, paresthesia in 15 out of 20 patients, ecchymosis in 16 out of 20 patients, and leg heaviness in 15 out of 20 patients. At the 3

Ciguatera poisoning appears after ingestion of contaminated fish from tropical coral reefs. Due to the diversity of clinical symptoms and the absence of a specific test in humans, the diagnosis is often difficult. A retrospective study of 10 patients consulting for a clinical and epidemiological picture compatible with ciguatera poisoning after a trip to tropical countries between 1993 and 2000. Most infections but one were acquired in the Caribbean area and there were 8 females. Clinical manifestations started within the first 24 hours after fish ingestion. Chief symptoms were diarrhea and nausea, followed by neurological symptoms, mainly limbs paresthesias that persisted for several weeks. The severity of clinical symptoms was variable and not related to age or initial symptoms. Ciguatera poisoning has to be considered in the diagnosis of acute gastroenteritis affecting travellers to tropical areas.

Ciguatera toxicity is a poisoning from consuming reef fish that had fed on dinoflagellates such as Gambierdiscus toxicus found along coral reefs. The toxin is oil soluble, odorless, colorless, tasteless, heat stable, and is concentrated in larger carnivorous fish such as amberjack, barracuda, eel, grouper, red snapper, sea bass, and Spanish mackerel. Onset of symptoms is usually within 6-12 hours after ingestion. Gastrointestinal symptoms lasting 1-2 days include abdominal pain, nausea, vomiting, and diarrhea. Neurological symptoms may persist for weeks or several months or--rarely--years and include circumoral and extremity paresthesias, temperature sensation reversal, itching, weakness, ataxia, and others. A patient with burning hands and feet who had not found relief using other methods had diagnosis of ciguatera toxicity assisted by hypnotically refreshed memory followed by rapid relief with hypnotic suggestions in 1 session and remained free of symptoms.

Full Text Available n-hexane neuropathy has been described after glue sniffing and industrial exposure. Onset may be subacute and reminiscent of Guillain-Barre' syndrome. Five patients (15-18 years old presented with paresthesia, severe weakness of the extremities particularly lower extremities, as well as muscular atrophy, total areflexia and gait disturbances were admitted in hospital in March 2003. All of these boys were workers of a small footwear production unit. They worked as gluers of leather pieces. Nerve conduction velocity studies showed latency prolongation and cerebrospinal fluid (CSF analysis showed normal protein. In the workplace assessment, it was found that hexacarbone-containing adhesives were used in an inappropriate ventilated place and without any personal protective devices. These patients were re-examined 8 months later. Sensory and autonomic symptoms were alleviated but two of them still had gait disturbance and decreased reflexes.

Fibromyalgia revisited: the challenge to a diagnoses remains

Directory of Open Access Journals (Sweden)

José Eduardo Martinez

2010-12-01

Full Text Available ABSTRACT Fibromyalgia is a clinical syndrome characterized by widespread musculoskeletal pain associated with areas of the body known as tender points which, when pressured gently, cause an exaggerated pain response. The most accepted physiopathological theory is that the pain in fibromyalgia results from an unbalance between the pain transmission stimulus mechanism and the pain inhibition one. The symptoms range from widespread musculoskeletal pain; disruptive sleep patterns; fatigue; short-lived generalized stiffness (generally in the morning; edema sensation and paresthesia. There is a constant association with other functional syndrome such as: depression, anxiety, migraine and irritable bowel syndrome. In 1990 The American College of Rheumatology developed a set of criteria to diagnose fibromyalgia and include it in scientific studies so as to help with the upcoming of a patient´s diagnosis and its follow up.

1999-07-01

Objective. To present a novel approach for treatment of intractable occipital neuralgia using percutaneous peripheral nerve electrostimulation techniques. Methods. Thirteen patients underwent 17 implant procedures for medically refractory occipital neuralgia. A subcutaneous electrode placed transversely at the level of C1 across the base of the occipital nerve trunk produced paresthesias and pain relief covering the regions of occipital nerve pain Results. With follow-up ranging from 1-½ to 6 years, 12 patients continue to report good to excellent response with greater than 50% pain control and requiring little or no additional medications. The 13th patient (first in the series) was subsequently explanted following symptom resolution. Conclusions. In patients with medically intractable occipital neuralgia, peripheral nerve electrostimulation subcutaneously at the level of C1 appears to be a reasonable alternative to more invasive surgical procedures following failure of more conservative therapies.

Five cases with development of syringomyelia, following long stable period of paraplegia after spinal trauma, have been studied with a resistive MRI unit. In all five cases there was spinal cord damage at the lower dorsal or dorsolumbar vertebral levels. Symptoms and signs of syringomyelia developed after long steady period with increased paresthesia, muscle weakness and pain of the shoulders and upper extremities. MRI revealed syringomyelia involving the dorsal and cervical cord up to the C1 or C2 level. The syringomyelia cavity was hypointense on T1 weighted images, but T2 weighted images showed isointensity in 2 of 4 cases showing no flow void. At the site of the cord injury there was diffuse increased signal intensity within the cord, probably indicating myelomalacia or gliosis. Pathogenesis of post-traumatic syringomyelia was discussed from the standpoint of diagnosis and treatment. (author)

Subacute combined degeneration (SCD) of the spinal cord is a neurological complication arising from vitamin B 12 deficiency. Typical findings are demyelination and axonal loss of the posterior and lateral columns of the thoracic and cervical spinal cord, leading to sensory ataxia and paresthesia. Clinical and neurological features and MRI findings all contribute to the diagnosis of this entity. In the Korean medical literature, only one case of of SCD involving pre-treatment MRI has been reported. We describe one case of SCD in a post-gastrectomy patient who initially presented with progressive sensory abnormality in both upper and lower extremities and showed T2 hyperintensity in the posterior and lateral columns of the spinal cord; this diminished, with clinical improvement, after vitamin B12 therapy. Our report includes the MR images obtained during follow up. (author)

A 38-year-old female presented with a trigeminal neurinoma manifesting as left facial paresthesia. The diagnosis was based on magnetic resonance (MR) imaging findings. Gamma knife radiosurgery (GKR) was performed at another hospital at her request. Fifteen months after the GKR, follow-up MR imaging revealed tumor regrowth causing extensive compression of the brainstem, and cyst formation in the tumor. Her clinical symptoms including facial pain and diplopia had worsened, so she was referred to our affiliated hospital for microsurgery. The tumor was totally resected, but the left trigeminal nerve had to be sacrificed because of pseudocapsule formation which covered both the tumor and the trigeminal nerve fibers. The diplopia disappeared, but her facial pain deteriorated after the operation. GKR can induce fibrosis or degenerative change in nearby structures, which may complicate subsequent surgery. (author)

Facial hemiatrophy: Review of literature and a case report

Directory of Open Access Journals (Sweden)

Manisha S Tijare

2011-01-01

Full Text Available A case report of hemifacial atrophy is presented in this paper. It is also known as Parry-Romberg syndrome, is an uncommon degenerative and poorly understood condition. It is characterized by progressive atrophy of the skin, subcutaneous tissue, muscle, cartilage or bone; the condition can leave a marked deformity on one side of the face. The incidence and the cause of this alteration is debatable. The most common complications that appear in association to this health disorder are: trigeminal neuritis, facial paresthesia, severe headache and epilepsy. Now, plastic surgery with graft of autogenous fat can be performed, after stabilization of the disease, to correct the deformity. Orthodontic treatment can help in the correction of any associated malformation. This presentation gives a review of concern literature about the etiology, physiopathology, differential diagnosis and treatment of hemifacial atrophy.

Transient urinary retention and chronic neuropathic pain associated with genital herpes simplex virus infection.

Genital herpes (GH) causes genital ulcer disease, severe transient pain, and often paresthesias. Whether or not GH can cause urinary retention or chronic neuropathic pain is not well known. We present two immunocompetent patients with GH associated with neuropathic symptoms. We also review the literature on GH and associated neurologic problems. Patient 1 had primary herpes simplex virus (HSV)-2 infection with transient urinary retention and chronic bilateral neuropathic pain in the sacral area. Patient 2 had recurrent HSV-1 associated with unitaleral chronic neuropathic pain in the sacral area. Although transient urinary retention associated with GH is not uncommon, chronic neuropathic pain has not been reported previously. Our cases show that chronic neuropathic pain, that is "pain initiated or caused by a primary lesion or dysfunction in the nervous system," can follow genital HSV infection.

2010-05-01

Extraction of impacted mandibular third molars (M3s) may cause temporary or permanent neurosensorial disturbances of the inferior alveolar nerve (IAN). Although the incidence of this complication is low, a great range of variability has been reported in the literature. Several methods to reduce or eliminate this complication have been proposed, such as orthodontic-assisted extraction, extraction of the second molar, or intentional odontoectomy. The purpose of this series of cases is to present a novel approach for a riskless extraction of impacted mandibular M3s in contact with the IAN. Nine consecutive patients (4 male and 5 female; mean age 24.9 years, range 18-43 years) required the extraction of 10 horizontally or mesioangular impacted mandibular M3s. In all cases the M3 was in contact with the IAN with a high risk of nerve injury. A staged approached was proposed and accepted by the patients. This approach consisted in the surgical removal of the mesial portion of the anatomic crown to create adequate space for mesial M3 migration. After the migration of the M3 had taken place, the extraction could then be accomplished in a second surgical session minimizing neurological risks. All M3s moved mesially within 6 months (mean 174.1 days, range 92-354 days) and could be successfully removed without any neurological consequences. This technique may be considered as an alternative approach to the extraction of horizontally or mesioangular impacted M3s in proximity to the IAN.

There are difficulties in procedure of regional block of 2 and 3 brunches of the trigeminal nerve despite availability of many different methods of nerves imaging. The difficulties are connected with complex anatomy structure. Neurostimulation not always effective and as a rule, is accompanied with wrong interpretation of movement response on stimulation. The changing of the tactics on paraesthesia search improves the situation. The use of new methods of nerves imaging (3D-CT) also allows decreasing the frequency of fails during procedure of regional block of the brunches of the trigeminal nerve.

Do carbamazepine, gabapentin, or other anticonvulsants exert sufficient radioprotective effects to alter responses from trigeminal neuralgia radiosurgery?

Laboratory studies have documented radioprotective effects with carbamazepine. We sought to determine whether carbamazepine or other anticonvulsant/neuroleptic drugs would show significant radioprotective effects in patients undergoing high-dose small-volume radiosurgery for trigeminal neuralgia. We conducted a retrospective review of 200 patients undergoing Gamma Knife (Elekta Instrument AB, Stockholm, Sweden) stereotactic radiosurgery for trigeminal neuralgia between February 1995 and May 2008. We selected patients treated with a maximum dose of 80 Gy with 4-mm diameter collimators, with no previous microvascular decompression, and follow-up ≥6 months (median, 24 months; range, 6-153 months). At the time of radiosurgery, 28 patients were taking no anticonvulsants, 62 only carbamazepine, 35 only gabapentin, 21 carbamazepine plus gabapentin, 17 carbamazepine plus other anticonvulsants, and 9 gabapentin plus other anticonvulsants, and 28 were taking other anticonvulsants or combinations. Pain improvement developed post-radiosurgery in 187 of 200 patients (93.5%). Initial complete pain relief developed in 84 of 200 patients (42%). Post-radiosurgery trigeminal neuropathy developed in 27 of 200 patients (13.5%). We could not significantly correlate pain improvement or initial complete pain relief with use of carbamazepine, gabapentin, or use of any anticonvulsants/neuroleptic drugs or other factors in univariate or multivariate analysis.

Purpose: Laboratory studies have documented radioprotective effects with carbamazepine. We sought to determine whether carbamazepine or other anticonvulsant/neuroleptic drugs would show significant radioprotective effects in patients undergoing high-dose small-volume radiosurgery for trigeminal neuralgia. Methods and Materials: We conducted a retrospective review of 200 patients undergoing Gamma Knife (Elekta Instrument AB, Stockholm, Sweden) stereotactic radiosurgery for trigeminal neuralgia between February 1995 and May 2008. We selected patients treated with a maximum dose of 80 Gy with 4-mm diameter collimators, with no previous microvascular decompression, and follow-up {>=}6 months (median, 24 months; range, 6-153 months). At the time of radiosurgery, 28 patients were taking no anticonvulsants, 62 only carbamazepine, 35 only gabapentin, 21 carbamazepine plus gabapentin, 17 carbamazepine plus other anticonvulsants, and 9 gabapentin plus other anticonvulsants, and 28 were taking other anticonvulsants or combinations. Results: Pain improvement developed post-radiosurgery in 187 of 200 patients (93.5%). Initial complete pain relief developed in 84 of 200 patients (42%). Post-radiosurgery trigeminal neuropathy developed in 27 of 200 patients (13.5%). We could not significantly correlate pain improvement or initial complete pain relief with use of carbamazepine, gabapentin, or use of any anticonvulsants/neuroleptic drugs or other factors in univariate or multivariate analysis.

Full Text Available Abstract Background There are no studies that have directly investigated the incremental reduction in sensory morbidity that lymphoscintigraphy images (LS and triangulated body marking or other skin marking techniques provide during sentinel lymph node biopsy (SLNB compared to using only the probe without LS and skin marking or using only dye. However, an indirect assessment of this potential for additional sensory morbidity reduction is possible by extracting morbidity data from studies comparing the morbidity of SLNB to that of axillary lymph node dissection. Methods A literature search yielded 13 articles that had data on sensory morbidity at specific time points on pain, numbness or paresthesia from SLNB that used radiotracer and probe or used only dye as a primary method of finding the sentinel node (SN. Of these, 10 utilized LS, while 3 did not utilize LS. By matching the data in studies not employing LS to the studies that did, comparisons regarding the percentage of patients experiencing pain, numbness/paresthesia after SLNB could be reasonably attempted at a cutoff of 9 months. Results In the 7 studies reporting on pain after 9 months (> 9 months that used LS (1347 patients, 13.8% of patients reported these symptoms, while in the one study that did not use LS (143 patients, 28.7% of patients reported these symptoms at > 9 months (P 9 months that used LS (601 patients, 12.5% of patients reported these symptoms, while in the 3 studies that did not use LS (229 patients, 23.1% of patients reported these symptoms at > 9 months (P = 0.0002. Similar trends were also noted for all these symptoms at ≤ 9 months. Conclusion Because of variations in techniques and time of assessing morbidity, direct comparisons between studies are difficult. Nevertheless at a minimum, a clear trend is present: having the LS images and skin markings to assist during SLNB appears to yield more favorable morbidity outcomes for the patients compared to performing

This prospective randomized study compared the coracoid and retroclavicular approaches to ultrasound-guided infraclavicular brachial plexus block (IBPB) in terms of needle tip and shaft visibility and quality of block. We hypothesized that the retroclavicular approach would increase needle tip and shaft visibility and decrease the number of needle passes compared to the coracoid approach. A total of 100 adult patients who received IBPB block for upper limb surgery were randomized into two groups: a coracoid approach group (group C) and a retroclavicular approach group (group R). In group C, the needle was inserted 2 cm medial and 2 cm inferior to the coracoid process and directed from ventral to dorsal. In group R, the needle insertion point was posterior to the clavicle and the needle was advanced from cephalad to caudal. All ultrasound images were digitally stored for analysis. The primary aim of the present study was to compare needle tip and shaft visibility between the coracoid approach and retroclavicular approach in patients undergoing upper limb surgery. The secondary aim was to investigate differences between the two groups in the number of needle passes, sensory and motor block success rates, surgical success rate, block performance time, block performance-related pain, patient satisfaction, use of supplemental local anesthetic and analgesic, and complications. Needle tip visibility and needle shaft visibility were significantly better in group R (p = 0.040, p = 0.032, respectively). Block performance time and anesthesia-related time were significantly shorter in group R (p = 0.022, p = 0.038, respectively). Number of needle passes was significantly lower in group R (p = 0.044). Paresthesia during block performance was significantly higher in group C (p = 0.045). There were no statistically significant differences between the two groups in terms of sensory or motor block success, surgical success, block-related pain, and patient satisfaction

Pareja, Juan A; Montojo, Teresa; Alvarez, Mónica

2012-04-01

Nummular headache is characterized by head pain exclusively felt in a rounded or elliptical area, typically 1 to 6 cm in diameter. The pain remains confined to the same symptomatic area, which does not change in shape or size with time. The symptomatic area may be localized in any part of the head but mostly in the parietal region. Rarely, the disorder may be multifocal, each symptomatic area keeping all the characteristics of nummular headache. The pain is generally mild or moderate, commonly described as oppressive or stabbing, and lasting minutes, hours, or days, with a remitting or unremitting pattern. Superimposed on the baseline pain, there may be spontaneous or triggered exacerbations. During and between symptomatic periods, the affected area may show variable combinations of hypoesthesia, dysesthesia, paresthesia, tenderness, and trophic changes. Nummular headache emerges as a primary disorder with a clear-cut clinical picture developed in a unique topography.

Acupuncture-induced Popliteal Arteriovenous Fistula Successfully Treated With Percutaneous Endovascular Intervention

Full Text Available A 39-year-old female visited our cardiovascular outpatient department with paresthesia and soreness around the right popliteal fossa, where thrill was palpable. There was no history of trauma, apart from her having undergone acupuncture several years previously. An arteriovenous fistula (AVF was diagnosed by vascular ultrasonography and magnetic resonance imaging. Angiography confirmed the presence of an AVF fed by the medial geniculate artery. Transarterial embolization was performed to close the AVF using coils and tissue adhesive. To the best of our knowledge, acupuncture-induced AVF has not been previously reported. We present a case demonstrating the merits of percutaneous endovascular intervention for treating this rare complication. The additional administration of a tissue adhesive can achieve complete closure of the AVF in the event of an unsatisfactory result following coil embolization. Doctors should be aware of the potential vascular complications of acupuncture, and of the management options.

Health care of people at work. Workers exposed to lead. I. Inorganic lead

Energy Technology Data Exchange (ETDEWEB)

Waldron, H.A.

1978-01-01

The risks associated with exposure to inorganic lead and the means by which these risks can be minimized are outlined. Lead is used to make a variety of metal products, the grids and oxides in storage batteries, pigments, chemicals, and also for lead plating. In the United States about 70% of the total lead consumption is related to transportation. Uptake of inorganic lead is by ingestion and inhalation. About 90% of the total body burden of lead is contained within the skeletal tissues. Lead is excreted in the kidney, in sweat, and in milk. Toxic effects are directed against the blood, the nervous system, and the kidney. Symptoms of lead poisoning are abdominal pain, constipation, vomiting, asthenia, paresthesia, psychological symptoms, and diarrhea. Physical and biological monitoring can serve to protect workers. Diagnosis of lead poisoning is not easy. Treatment involves removal from exposure and/or treatment with a chelating agent.

2002-01-01

Diabetic neuropathy is a clinical state of nerve damage caused by hyperglicaemia, raised activation of polyol pathway, oxydative stress, changes in endoneurial arteries and myelinated fibres. Patient complains of pain and paresthesiae in hands and limbs. The feelings of pain, temperature, touch, vibration are significantly reduced. The changes may also concern cranial nerves (IIII, IV, VI, VII), intracostal nerves, hands and limbs (Garland and Tavemer syndrome). Autonomic neuropathy concerns the impairment of autonomic functions of cardio-vascular, gastro-intestinal, uro-genital and other systems. The treatment concerns the improvement of diabetes metabolic control. Antiinflammatory antisteroid drugs are widely used but their usefulness is limited. Antidepressive drugs are the most often used group. The improvement is observed after 6 months of treatment. The side effects - orthostatic hypotension, heart rhythm disturbation and obstipation are harmful for the patients with coronary heart disease. In the cases of persistent pain the oral antiepileptic drugs may be used or cream with capsaicin for skin surface.

Neurolymphomatosis is a rare condition defined as an infiltration of nerves, nerve roots or nervous plexuses by haematological malignancy. Its diagnosis may sometimes be difficult with conventional imaging techniques. This paper aims to emphasize the importance of this entity and the role of (18)F-FDG PET/CT in this indication. We present the case of a 53-year-old male who complained of sharp pain in his right hip and right leg paresthesia after 2 years of complete remission from Non-Hodgkin's lymphoma. Physical examination and CT scan were negative and the lumbar MRI showed protrusion of L5-S1 disc. Physiotherapy, nonsteroid antiinflammatory drugs and steroids were inefficient. PET/CT was performed four months after the onset of the symptoms, revealing focal FDG uptake in the right S1 nerve root and linear FDG uptake along the right sacral plexus suggesting relapse. This was confirmed by histology. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

COMPLICATIONS AFTER EXTRACTION OF IMPACTED THIRD MOLARS - LITERATURE REVIEW

Directory of Open Access Journals (Sweden)

Elitsa G. Deliverska

2016-07-01

Full Text Available Third molar surgery is the most common procedure performed by oral and maxillofacial surgeons worldwide. This article addresses the incidence of specific complications and, where possible, offers a preventive or management strategy. Complications, such as pain, dry socket, swelling, paresthesia of the lingual or inferior alveolar nerve, bleeding, and infection are most common. Factors thought to influence the incidence of complications after third molar removal include age, gender, medical history, oral contraceptives, presence of pericoronitis, poor oral hygiene, smoking, type of impaction, relationship of third molar to the inferior alveolar nerve, surgical time, surgical technique, surgeon experience, use of perioperative antibiotics, use of topical antiseptics, use of intra-socket medications, and anaesthetic technique. For the general dental practitioner, as well as the oral and maxillofacial surgeon, it is important to be familiar with all the possible complications after this procedure. This improves patient education and leads to prevention, early recognition and management.

Full Text Available Objective. The present study was aimed at evaluating the use of mechanical and manual lymphatic therapy as a treatment for lymphedema resulting from orthopedic surgery that became painful after an episode of erysipelas. Case Report. A 70-year-old male patient suffered direct trauma resulting in a compound fracture of the tibia and fibula of the left leg. He was treated with an external fixator for four months followed by plaster cast immobilization for three weeks. He presented with fever and paresthesia in the lower left limb that resulted in an episode of erysipelas, and the patient evolved with painful lymphedema. Treatment using the Godoy and Godoy technique was proposed, including manual and mechanical lymphatic therapy. Water displacement volumetry was used to quantify the leg size reduction. Results. After 10 sessions of therapy, the patient presented a significant reduction in the limb volume and remission of symptoms. Conclusions. The method used may be a promising option for the treatment of posttraumatic edemas with pain.

The aim of this study was to confirm the effectiveness of a real-time three-dimensional navigation system for use during various oral and maxillofacial surgeries. Five surgeries were performed with this real-time three-dimensional navigation system. For mandibular surgery, patients wore acrylic surgical splints when they underwent computed tomography examinations and the operation to maintain the mandibular position. The incidence of complications during and after surgery was assessed. No connection with the nasal cavity or maxillary sinus was observed at the maxilla during the operation. The inferior alveolar nerve was not injured directly, and any paresthesia around the lower lip and mental region had disappeared within several days after the surgery. In both maxillary and mandibular cases, there was no abnormal hemorrhage during or after the operation. Real-time three-dimensional computer-navigated surgery allows minimally invasive, safe procedures to be performed with precision. It results in minimal complications and early recovery.

The purpose of this study was to determine the efficacy and stability of the biodegradable fixation system for treatment of mandible fractures in pediatric patients by measuring the bite force. Sixty pediatric patients with mandibular fractures (36 males, 24 females) were included in this study. The 2.5-mm resorbable plates were adapted along Champy's line of ideal osteosynthesis and secured with four 2.5 mm diameter monocortical resorbable screws, 8 mm in length. All patients were followed for 10 months. Clinical parameters, such as soft tissue infection, nonunion, malunion, implant exposure, malocclusion, nerve injury, and bite force for stability, were prospectively assessed. Adequate fixation and primary bone healing was achieved in 100% of the cases. Six minor complications (10%) were observed: 2 soft tissue infections (3%), 1 plate dehiscence (2%), 1 malocclusion (2%), and 2 paresthesia (3%). 2.5-mm resorbable plating system along Champy's line of ideal osteosynthesis is a good treatment modality for mandible fractures in pediatric patients.

Full Text Available OBJECTIVE: To analyze retrospectively 309 fractures in the clavicle and the relation with injury of the supraclavicular nerve after trauma. METHODS: It was analyzed 309 patients with 312 clavicle fractures. The Edinburgh classification was used. Four patients had fractures in the medial aspect of the clavicle, 33 in the lateral aspect and 272 in the diaphyseal aspect and three bilateral fractures. RESULTS: 255 patients were analyzed and five had paresthesia in the anterior aspect of the thorax. Four patients had type 2 B2 fracture and one type 2 B1 fracture. All patients showed spontaneous improvement, in the mean average of 3 months after the trauma. CONCLUSION: Clavicle fractures and/ or shoulder surgeries can injure the lateral, intermediary or medial branches of the supraclavicular nerve and cause alteration of sensibility in the anterior aspect of the thorax. Knowledge of the anatomy of the nerve branches helps avoid problems in this region.

Solitary intracranial tuberculoma mimicking a malignant tumor in a patient without tubercular lesions or a history of disease: a case report

Directory of Open Access Journals (Sweden)

Javier A. Bustamante-Rengifo

2013-05-01

Full Text Available Cerebral tuberculoma is a rare cause of intracranial mass. In Latin America and Colombia where tuberculosis is endemic, it represents between 5 and 30% of brain tumours. A 53-year-old Colombian woman was admitted to a third-level hospital in Cali, Colombia, after reporting loss of consciousness, headache, paresthesia, and flight of ideas for a two-week period. Imaging studies showed a left frontal mass of malignant appearance whose first possible diagnosis was metastatic neoplasia or glioma. With the initial results, absence of history of chronic infectious diseases and a history of thyroidectomy, a surgical procedure was carried out and a histopathological and molecular evaluation was conducted. The pathology report noted necrotizing granulomatous inflammation and tissue staining and molecular tests for detection of M. tuberculosis were positive and the patient was managed with anti-tubercular treatment. Intracranial masses are frequently targeted as a malignant neoplastic disease for surgical treatment. Considering an infectious etiology must be a diagnostic option.

A Case with Bilateral Periventricular Nodular Heterotopia Diagnosed as Depression

Directory of Open Access Journals (Sweden)

Melek Kandemir

2010-06-01

Full Text Available Periventricular nodular heterotopia is a form of neuronal migration abnormality. Periventricular nodular heterotopia can easily be recognized by cranial magnetic resonance imaging. The most common clinical appearance is epileptic seizures. In some cases, symptoms are accompanied with psychiatric complaints. In this article, we report a 33-year-old female with complaints of left-sided paresthesia induced by emotional stress. She had been followed at an outpatient psychiatry clinic for about 10 years with the diagnosis of somatization disorder. Her electroencephalography recordings -awake as well as during sleep- were found to be normal. The cranial magnetic resonance imaging showed bilateral periventricular nodular heterotopia. Her seizures were controlled with carbamazepine treatment. Partial epileptic seizures might also be observed, even though the cerebral heterotopic lesions are bilateral. When a history is obtained from a patient with somatoform complaints, it should be kept in mind that these symptoms might be seizures, and the patient should be questioned accordingly

A tapered mandibular contour is popular with Far Eastern Asians. This study describes a safe and accurate method of using preoperative virtual surgical planning (VSP) and an intraoperative ostectomy guide to maximize the esthetic outcomes of mandibular symmetry and tapering while mitigating injury to the inferior alveolar nerve (IAN). Twelve subjects with chief complaints of a wide and square lower face underwent this protocol from January to June 2015. VSP was used to confirm symmetry and preserve the IAN while maximizing the surgeon's ability to taper the lower face via mandibular inferior border ostectomy. The accuracy of this method was confirmed by superimposition of the perioperative computed tomography scans in all subjects. No subjects complained of prolonged paresthesia after 3 months. A safe and accurate protocol for achieving an esthetic lower face in indicated Far Eastern individuals is described. Copyright © 2016 International Association of Oral and Maxillofacial Surgeons.

The clinical features of bites from Texas coral snakes (Micrurus tener) have not been well studied. Our goal was to review the largest number of victims of Texas coral snakebites to determine their characteristics, effects, treatment, and outcome. Retrospective case series of Micrurus tener exposures reported to the Texas Poison Center Network from 2000 to 2004. Eighty-two patients were included in the analysis. Most (57.3%) were 18 to 49-year-old men. Almost 90% had local swelling, pain, erythema, or paresthesias. Only 7.3% had systemic effects, and none of these were severe. Over half received coral snake antivenin, and 15.9% were given opioids for pain. No patient died and no patient required mechanical ventilation due to hypoventilation from the snakebite. There were more local findings and less severe systemic effects than previously reported. Antivenin is not needed for most of these patients, and opioids may be administered safely.

Churg-Strauss syndrome (CSS) is a rare systemic vasculitis that affect small and medium-sized blood vessels and is accompanied by asthma, eosinophilia, and peripheral neuropathy. This report describes a case of a 52-year-old man who had a history of sinusitis, asthma, and thymus cancer and who had complained of bilateral lower extremity paresthesia and weakness for a month. Peripheral neuropathy was detected by electrodiagnostic studies. Resection of a mediastinal mass, which was diagnosed as thymic neuroendocrine carcinoma, was performed five months before his visit. After thymectomy, peripheral blood tests revealed a gradual increase in eosinophils. Two months after surgery, he was admitted to the hospital for dyspnea, and nodules of focal consolidation were found in his chest X-ray. One month later, pyoderma occurred in the right shin, and the skin biopsy showed extravascular eosinophilic infiltration. He was diagnosed with CSS after thymectomy, and we report a very rare case of CSS presented with thymic neuroendocrine carcinoma.

Veratrum album (white or false hellebore) is a poisonous plant containing steroidal alkaloids that cause nausea, vomiting, headache, visual disturbances, paresthesia, dizziness, bradycardia, atrioventricular block, hypotension, and syncope. It is regularly mistaken for Gentiana lutea (yellow gentian). We report accidental poisoning with V. album mistaken for Allium ursinum (wild garlic), a wild plant used in soups and salads in Central Europe. Four adults (24-45 years) accidentally ingested V. album mistaken for A. ursinum in self-prepared salads and soups. Within 15-30 min of ingestion they developed nausea, vomiting, and abdominal pain. At the same time dizziness, tingling, dimmed and jumping vision, transient blindness, and confusion appeared. On arrival at the ED, all patients had sinus bradycardia and hypotension. Following treatment the patients were discharged well 24-48 h after ingestion. In patients presenting with gastrointestinal, neurological, and cardiovascular symptoms a history of wild plant ingestion suggests possible poisoning with V. album mistaken for wild garlic.

Full Text Available We report a case of a 43-year-old female who presented with right ear fullness and otorrhea. She was initially diagnosed with mastoiditis that was not responsive to multiple courses of antibiotics and steroids. She was then diagnosed with refractory inflammatory pseudotumor, and subsequent treatments included several mastoidectomies, further steroids, and radiation therapy. The patient went on to develop mastoiditis on the contralateral side as well as central nervous system involvement with headaches and right-sided facial paresthesias. Reexamination of the mastoid tissue revealed a significantly increased number of IgG4-positive cells, suggesting a diagnosis of IgG4-related disease. The patient improved clinically and radiographically with rituximab and was able to taper off azathioprine and prednisone. IgG4-related disease should be considered in patients with otologic symptoms and be on the differential diagnosis in patients with inflammatory pseudotumor. Staining for IgG and IgG4 is essential to ensure a prompt diagnosis and treatment.

A dangerous mixture

Full Text Available A 59-year old woman was admitted for fatigue and arm paresthesias with Trousseau sign. Her medical history included thyroidectomy and hypercholesterolemia recently treated with simvastatin. Laboratory tests showed severe hypokalemia and hypocalcemia, severe increase in muscle enzymes, metabolic alkalosis; low plasma renin activity, increased thyroid-stimulating hormone, normal free thyroxine, increased parathyroid hormone, decreased vitamin D3; alterations in electrolyte urinary excretion, cortisol and aldosterone were excluded. Hypothesizing a statin-related myopathy, simvastatin was suspended; the patient reported use of laxatives containing licorice. Electrolytes normalized with intravenous supplementation. Among many biochemical alterations, none stands out as a major cause for muscular and electrolyte disorders. All co-factors are inter-connected, starting with statin-induced myopathy, worsened by hypothyroidism, secondary hyperaldosteronism and vitamin D deficiency, leading to hypocalcemia and hypokalemia, perpetrating muscular and electrolyte disorders. The importance of considering clinical conditions as a whole emerges with multiple co-factors involved. Another issue concerns herbal products and their potential dangerous effects.

Acute compartment syndrome (ACS) is an uncommon complication of uncontrolled hypothyroidism. If unrecognized, this can lead to ischemia, necrosis and potential limb loss. A 49-year-old female presented with the sudden onset of bilateral lower and upper extremity swelling and pain. The lower extremity anterior compartments were painful and tense. The extensor surface of the upper extremities exhibited swelling and pain. Motor function was intact, however, limited due to pain. Bilateral lower extremity fasciotomies were performed. Postoperative Day 1, upper extremity motor function decreased significantly and paresthesias occurred. She therefore underwent bilateral forearm fasciotomies. The pathogenesis of hypothyroidism-induced compartment syndrome is unclear. Thyroid-stimulating hormone-induced fibroblast activation results in increased glycosaminoglycan deposition. The primary glycosaminoglycan in hypothyroid myxedematous changes is hyaluronic acid, which binds water causing edema. This increases vascular permeability, extravasation of proteins and impaired lymphatic drainage. These contribute to increased intra-compartmental pressure and subsequent ACS.

Angiostrongylus eosinophilic meningitis is caused by infection with larvae of the rat lungworm, Angiostrongylus cantonensis. We report the case of an adult who ingested a raw, giant African snail (Achatina fulica) on the island of O‘ahu in Hawai‘i and developed an eosinophilic meningoencephalitis with severe headache, confusion, sixth cranial nerve palsy, ataxia, limb weakness, and paresthesia. He was treated with lumbar punctures to relieve pressure, high dose corticosteroids, and 14 days of albendazole. He had a prolonged convalescence, requiring 3 months of prednisone, and still had evidence of motor nerve weakness 4 months after exposure. A field investigation at the site of exposure yielded 5 of 9 Achatina fulica snails with evidence of A. cantonensis DNA by PCR. Cerebrospinal fluid samples from the patient were negative acutely but positive on day 15 of symptoms, using an investigational, real-time PCR assay. We discuss clinical management of this case in light of the current medical literature. PMID:23901383

A significant number of patients with essential thrombocythemia (ET) complain of symptoms including distal parts of the extremities (e.g., paresthesias or Raynaud's phenomenon). The aim of the present study was to examine peripheral circulation in the upper extremities of individuals with ET. The study included 45 ET patients and 30 control subjects. All participants were subjected to thermography, photoplethysmography, impedance plethysmography, and applanation tonometry pulse wave analysis. The patients with ET differed significantly from the control subjects in terms of 3rd finger skin temperature (mean 31.04 vs. 32.45°C), skin temperature gradient (mean 1.82 vs. 0.11°C), photoplethysmographic amplitude (median 0.25 vs. 0.74%), and pulse waveform in the radial artery (more frequent occurrence of type B waveform). Pulse wave parameters correlated with the skin temperature gradient. The study findings imply the altered regulation of peripheral circulation in ET, including a decreased flow and an increased resistance. Copyright © 2017 Elsevier Inc. All rights reserved.

Pleural puncture with thoracic epidural: A rare complication?

Full Text Available Freedom from pain has almost developed to be a fundamental human right. Providing pain relief via epidural catheters in thoracic and upper abdominal surgeries is widely accepted. Pain relief through this technique not only provides continuous analgesia but also reduces post-operative pulmonary complications and also hastens recovery. But being a blind procedure it is accompanied by certain complications. Hypotension, dura puncture, high epidural, total spinal, epidural haematoma, spinal cord injury and infection are some of the documented side effects of epidural block. There are case reports eliciting neurological complications, catheter site infections, paresthesias, radicular symptoms and worsening of previous neurological conditions. Few technical problems related to breakage of epidural catheter are also mentioned in the literature. The patient had no sequelae on long term follow up even when a portion of catheter was retained. We present a case report where epidural catheter punctured pleura in a patient undergoing thoracotomy for carcinoma oesophagus.

2014-01-01

Palpitations, paresthesias and anxiety are very common reasons of consultation in primary care. We report the case of a 40 year-old Caucasian woman who came to the clinic due to these symptoms, and was finally diagnosed with Takayasu arteritis. Later, she had an episode of headache, as the initial manifestation of cerebral venous thrombosis. Takayasu arteritis is a systemic vasculitis affecting medium and large arteries, mainly leacausing stenosis of the aorta and its branches. It most frequently affects Asian women, being much rarer in Europe. The primary care doctor plays a key role in the initial diagnosis and monitoring of patients with rare diseases, such as Takayasu arteritis, and must be a basic support for the patient and family, providing information and advice, and contributing with his work to reduce the vulnerability of this group.

2010-06-01

Full Text Available Periventricular nodular heterotopia is a form of neuronal migration abnormality. Periventricular nodular heterotopia can easily be recognized by cranial magnetic resonance imaging. The most common clinical appearance is epileptic seizures. In some cases, symptoms are accompanied with psychiatric complaints. In this article, we report a 33-year-old female with complaints of left-sided paresthesia induced by emotional stress. She had been followed at an outpatient psychiatry clinic for about 10 years with the diagnosis of somatization disorder. Her electroencephalography recordings -awake as well as during sleep- were found to be normal. The cranial magnetic resonance imaging showed bilateral periventricular nodular heterotopia. Her seizures were controlled with carbamazepine treatment. Partial epileptic seizures might also be observed, even though the cerebral heterotopic lesions are bilateral. When a history is obtained from a patient with somatoform complaints, it should be kept in mind that these symptoms might be seizures, and the patient should be questioned accordingly.

A 31-year-old male with severe limitation of mouth opening was referred to our department of Chonbuk National University Hospital. The physical status of the patient was hyposthenic. Extraoral examination showed no condylar movement of the both temporomandibular joints, no pain, no faical swelling or paresthesia. Intraoral examination showed several cervical caries on the upper anterior teeth, and gingival swelling on the whole dentition. Transcranial view showed no condylar movement, and narrowing of joint spaces. Chest P-A view showed straightening of thoracic, lumbar spine, and squaring of vertebrae of the same spines. Conventional lateral radiograph of cervical spine showed calcification of the intervertebral ligament. Computed tomograph showed extensive bone formation between temporal bone and the both condylar heads. Labortory findings showed positive reaction on HLA-B27 histocompatibility antigen and increased level of IgA, IgG, ESR. Based on the clinical, radiographic, and the labortary findings, final diagnosis was made as bony ankylosis of the both temporomandibular joints secondary to ankylosing spondylitis.

A 51-year-old woman had been exposed to a high concentration of trichloroethylene for about 12 years. She had been employed in a factory where metal screws and washers for automobiles were manufactured. She had been engaged in dipping baskets of the screws and washers into an open bath of trichloroethylene. She first experienced symptoms of dizziness and headaches after degreasing the screws and washers. She also experienced sleepiness and fatigability, as well as paresthesia in the feet, hands and around the mouth. The muscle strength and tendon reflexes of the extremities were weakened: coordination was slightly clumsy and slow; and her gait was lightly paretic. Air samples were analyzed by gas chromatography and concentrations in the breathing zone of the worker were very high (579 and 792 ppm). It can be concluded from this investigation that peripheral nerve impairment is one of the important signs in chronic trichloroethylene poisoning. 15 references, 2 figures, 1 table.

A giant plexiform schwannoma of the brachial plexus: case report

2011-11-01

Full Text Available Abstract We report the case of a patient who noticed muscle weakness in his left arm 5 years earlier. On examination, a biloculate mass was observed in the left supraclavicular area, and Tinel's sign caused paresthesia in his left arm. Magnetic resonance imaging showed a continuous, multinodular, plexiform tumor from the left C5 to C7 nerve root along the course of the brachial plexus to the left brachia. Tumor excision was attempted. The median and musculocutaneous nerves were extremely enlarged by the tumor, which was approximately 40 cm in length, and showed no response to electric stimulation. We resected a part of the musculocutaneous nerve for biopsy and performed latissimus dorsi muscle transposition in order to repair elbow flexion. Morphologically, the tumor consisted of typical Antoni A areas, and immunohistochemistry revealed a Schwann cell origin of the tumor cells moreover, there was no sign of axon differentiation in the tumor. Therefore, the final diagnosis of plexiform Schwannoma was confirmed.

MRI-guided cryoablation of the posterior femoral cutaneous nerve for the treatment of neuropathy-mediated sitting pain

2017-01-01

Neuropathy of the posterior femoral cutaneous nerve may manifest as pain and paresthesia in the skin over the inferior buttocks, posterior thigh, and popliteal region. Current treatment options include physical and oral pain therapy, perineural injections, and surgical neurectomy. Perineural steroid injections may provide short-term pain relief; however, to our knowledge, there is currently no minimally invasive denervation procedure for sustained pain relief that could serve as an alternative to surgical neurectomy. Percutaneous cryoablation of nerves is a minimally invasive technique that induces a sustained nerve conduction block through temporary freezing of the neural layers. It can result in long-lasting pain relief, but has not been described for the treatment of neuropathy-mediated PFCN pain. We report a technique of MR-guided cryoablation of the posterior femoral cutaneous nerve resulting in successful treatment of PFCN-mediated sitting pain. Cryoablation of the posterior femoral cutaneous nerve seems a promising, minimally invasive treatment option that deserves further investigation. (orig.)

Methamphetamine Related Radiculopathy: Case Series and Review of Literature

Directory of Open Access Journals (Sweden)

Mohsen Foroughipour

2013-06-01

Full Text Available Background: Peripheral nervous injury and neuromuscular complications from methamphetamine abuse has not been reported. The mechanism is not yet identified. Methods: Eight patients with lower extremity weakness following methamphetamine abuse were reported during December 2009 to May 2010. Results: Patients presented with lower extremity weakness. All patients were co-abusers of methamphetamine and opioids. Other clinical manifestations comprised of distal paresthesia of the lower extremities with progression to proximal portions, with minimal sensory involvement in the distal of the lower extremities. Electrodiagnostic findings were consistent with lumbosacral Radiculopathy. Vital signs were unremarkable and all laboratory tests were within normal limits. Follow-up examination after three months showed improvement of weakness in 3 patients. Conclusion: For patients with a history of illicit drug abuse and acute neuromuscular weakness, methamphetamine or heroin toxicity should be taken into account. Hence, urine morphine and amphetamine/ methamphetamine tests should be performed and serum lead and thallium levels should be evaluated. In addition, rhabdomyolysis and myoglobinuria should be worked up.

Ilizarov process is used for the management of multiple fractures, polytrauma conditions, cosmetic limb lengthening, and fracture malunion. Complications associated with the process are nerve palsy, joint contracture, premature or delayed osseous consolidation, a nonunion and permanent stiffness of the joint, pin tract infection, edema, and transient paresthesia, etc. In our case, there was a fatal complication. A 25-year-old African lady underwent the Ilizarov procedure for femur lengthening in a hospital in New Delhi, India. During her first distraction process, she suddenly collapsed at the hospital and could not be revived. At postmortem, a small hematoma was seen around the surgically fractured area. On histopathology of internal organs, fat globules were present in the vasculature of brain and lungs. Cause of death was opined as due to fat embolism. This is the first case reported of a fatal fat embolism following Ilizarov procedure for limb lengthening in a healthy adult. © 2018 American Academy of Forensic Sciences.

Autoantibodies against voltage-gated potassium channels (VGKC-Abs) are associated with acquired neuromyotonia (Isaacs' syndrome) and related disorders such as Morvan's syndrome and some cases of limbic encephalitis. The mechanisms underlying the various phenotypes induced by VGKC-Abs are not fully understood. Recently, we reported a case of LE with VGKC-Abs accompanied by severe intestinal pseudo-obstruction and thymoma. Thymectomy and immunosuppressive therapy induced dramatic clinical improvement of LE symptoms, and VGKC-Abs titers decreased from 1254 pM to 549 pM (normal>100 pM). Seventeen months later, the patient developed progressive generalized muscle cramping, paresthesias in his lower extremities, excessive sweating, and severe constipation. There was no recurrence of the LE. Electromyography showed fasciculation potentials and myokymic discharges, and the plasma VGKC-Abs titer was again elevated to 879 pM. Here we report a case of Isaacs' syndrome after complete remission of LE with VGKC-Abs that may provide an insight into a possible link among VGKC-Abs associated syndromes.

Gout Initially Mimicking Rheumatoid Arthritis and Later Cervical Spine Involvement

Eduardo Araújo Santana Nunes

2014-01-01

Full Text Available Gout is clinically characterized by episodes of monoarthritis, but if not treated properly, it can lead to a chronic polyarthritis, which may eventually mimic rheumatoid arthritis (RA. We present the case of a 59-year-old man, with a history of symmetrical polyarthritis of the large and small joints with later development of subcutaneous nodules, which was initially misdiagnosed as RA, being treated with prednisone and methotrexate for a long period of time. He complained of occipital pain and paresthesia in his left upper limb, and computed tomography (CT and magnetic resonance imaging (MRI revealed the presence of an expansive formation in the cervical spine with compression of the medulla. He was admitted for spinal decompressive surgery and the biopsy specimen demonstrated a gouty tophus. Chronic gout can mimic RA and rarely involves the axial skeleton, and thus its correct diagnosis and the implementation of adequate therapy can halt the development of such damaging complications.

To investigate the safety of trivalent seasonal influenza vaccine (TIVc) (Optaflu ® ), the first cell culture seasonal trivalent influenza vaccine available in Europe. Codes and unstructured text in adult electronic healthcare records (The Health Improvement Network) were searched for a TIVc brand name or batch number and possible outcomes within a 3 month pre- to 6 month post-TIVc exposure study period (2012-2015). The outcomes were severe allergic reactions, Bell's palsy, convulsions, demyelination, paresthesia, noninfectious encephalitis, neuritis (optic and brachial), vasculitis, inflammatory bowel disease, and thrombocytopenia. Risk periods were defined based on biologically plausible time frame postvaccination when an outcome caused by the vaccine might be expected to occur. Possible outcomes were adjudicated against outcome specific case definitions and a date of onset assigned by using electronic and other medical records. Observed (risk period) to expected (outside risk and preexposure periods) rate ratios, postexposure incidence, and plots of time from exposure to outcome were reported. Sixteen of 1011 events from 4578 exposures fulfilled a primary case definition and had a date of onset during the study period. Three were in observed time. The observed-to-expected rate ratios were (3.3, 95% CI 0.3, 31.7) for convulsions and (1.5, 95% CI 0.2, 14.9) for thrombocytopenia with 1 outcome each in observed time. There was 1 incident inflammatory bowel disease in observed, but none in expected, time. The small sample size restricts interpretation; however, no hypothesis of an increased risk of a study outcome was generated. Adjudication of events against case definitions to reduce misclassification of onset and outcomes allowed use of precise risk periods. KEY POINTS This observational study did not generate a hypothesis of an association between the first cell-culture seasonal influenza vaccination available in the European Union and any of the study

Although linezolid is known to be effective when used as an adjunct therapy in the treatment of patients with multidrug-resistant tuberculosis (MDR-TB), the clinical experience is limited. In this study the efficacy and adverse effects of linezolid treatment were evaluated. A retrospective study of tolerability and efficacy of linezolid in MDR-TB patients was performed in Madrid, Spain. Demographic characteristics, microbiological and clinical features and data on treatment tolerability were collected. Regimens were constructed with a target of prescribing, at least, five anti-tuberculosis agents likely to be effective. Linezolid, at a dosage of 1200 or 600 mg daily, was included to complete the treatment if no other sensitive drugs were available. Vitamin B6 was used to reduce toxicity. Treatment outcome and clinical status at last contact were compared between patients with linezolid-containing regimens and with those without linezolid-containing regimens. During the period 1998-2014, 55 patients with MDR-TB received treatment. In 21 of these patients, linezolid was added. The median of linezolid administration was 23.9 months (IQT 13.1-24.7). Patients using linezolid showed a greater resistance to drugs, with a median of 6 (IQR 5-7) compared with those who did not use it, with a median of 4 drugs (IQR 3-5) (plinezolid group (73.5 days) did not differ significantly from those in the non-linezolid group (61 days) (p=0.29). There were no significant differences in the outcomes of the two patient groups. There were no reported adverse events in 81% of patients assigned to linezolid therapy. Only four patients developed toxicity attributed to linezolid. The most serious adverse event in these patients was anemia observed in the two patients treated with 1200 mg per day. One of them also developed moderate paresthesia. In both cases the dosage was reduced to 600 mg per day, with improvement of the anemia and paresthesias. No patients stopped linezolid therapy.

Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU, incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons. Materials and methods: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 lumbar laminectomy and diskectomy surgeries were identified, with 183 undergoing general anesthesia and 361 undergoing spinal anesthesia (SA. Linear and multivariate regression analyses were performed to identify differences in blood loss, operative time, time from entering the operating room (OR until incision, time from bandage placement to exiting the OR, total anesthesia time, PACU time, and total hospital stay. Secondary outcomes of interest included incidence of postoperative spinal hematoma and death, incidence of paraparesis, plegia, post-dural puncture headache, and paresthesia, among the SA patients. Results: SA was associated with significantly lower operative time, blood loss, total anesthesia time, time

Neurologic sequelae associated with foscarnet therapy.

Science.gov (United States)

Lor, E; Liu, Y Q

1994-09-01

To report three cases of possible foscarnet-induced neurologic sequelae. We report two cases of seizures and one case of hand cramping and finger paresthesia after starting foscarnet therapy with no evidence of predisposing risk factors, such as serum laboratory abnormalities, renal dysfunction, or known central nervous system (CNS) involvement. All three patients had stable laboratory values during therapy and when the neurologic adverse effects occurred. All patients were receiving appropriate dosages of foscarnet. The incidence of seizures in AIDS patients was reviewed. A history of CNS lesions, infections, and/or AIDS per se may increase the risk of a neurologic adverse effect while receiving foscarnet therapy. Acute ionized hypocalcemia may cause these neurologic adverse effects. Ionized hypocalcemia is transitory, is related to the rate of foscarnet infusion, and may not be reflected as a change in total serum calcium concentration. Foscarnet probably contributed to the neurologic adverse effects reported here. Foscarnet may need to be administered at a slower rate than is recommended by the manufacturer. Electrolytes must be monitored closely; however, a neurologic adverse effect may not be foreseen.

Behavior as a sentry of metal toxicity

Energy Technology Data Exchange (ETDEWEB)

Weiss, B.

1978-01-01

Many of the toxic properties of metals are expressed as behavioral aberrations. Some of these arise from direct actions on the central nervous system. Others arise from primary events elsewhere, but still influence behavior. Toxicity may be expressed either as objectively measurable phenomena, such as ataxia, or as subjective complaints, such as depression. In neither instance is clinical medicine equipped to provide assessments of subtle, early indices of toxicity. Reviewers of visual disturbances, paresthesia, and mental retardation exemplify the potential contribution of psychology to the toxicology of metals. Behavior and nervous system functions act as sensitive mirrors of metal toxicity. Sensitivity is the prime aim in environmental health assessments. Early detection of adverse effects, before they progress to irreversibility, underlies the strategy for optimal health protection. Some of the toxic actions of metals originate in direct nervous system dysfunction. Others may reflect disturbances of systems less directly linked to behavior than the central nervous system. But behavior, because it expresses the integrated functioning of the organism, can indicate flaws in states and processes outside the nervous system.

[Imported tropical fish causes ciguatera fish poisoning in Germany].

Science.gov (United States)

Zimmermann, Katharina; Eisenblätter, Anneka; Vetter, Irina; Ebbecke, Martin; Friedemann, Miriam; Desel, Herbert

2015-01-01

Ciguatera is a seafood-borne illness caused by consumption of tropical fish contaminated with ciguatoxins, lipophilic polyethers that are produced in benthic dinoflagellates and accumulate through the marine food chain. Ciguatera cases in Europe usually occur in travellers returning from tropical and subtropical regions of the Pacific and Carribean, where ciguatera is endemic. In 2012, several cases of ciguatera occurred in Germany due to sale of contaminated fish products originating from the Indian Ocean. Although the symptomatology in these cases were typical of ciguatera, with patients reporting gastrointestinal discomfort including nausea, vomiting and diarrhea as well as neurological effects including widespread intense pruritus, paresthesias, hypothermia or altered temperature sensation and diffuse pain, correct diagnosis was delayed in all cases due to lack of awareness of the treating medical practitioners. In light of increasing global mobility, trade, and occurrence of ciguatoxic fish in previously non-endemic areas, ciguatera should be considered as a possible diagnosis if gastrointestinal and neurological symptoms occur shortly after consumption of fish.

Hydroxychloroquine is an oral antimalarial medication commonly used off-label for a variety of rheumatological conditions, including systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome and dermatomyositis. We present a case of a 64-year-old woman who presented with acute onset headache, bilateral tinnitus, and left-sided facial numbness and tingling in the setting of accidentally overdosing on hydroxychloroquine. By the next morning, the patient began to experience worsening in the tingling sensation and it eventually spread to her left arm, thigh and distal extremities. The patient also complained of new onset blurring of her peripheral vision and feeling 'off balance.' Despite a complete neurological and ophthalmological work-up with unremarkable imaging and blood work, the patient has had no improvement in her tinnitus, left-sided paresthesias, visual disturbance or ataxia. This is a unique case of hydroxychloroquine overdose resulting in permanent neurotoxic vestibulopathy. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Aims The purpose of this study was to determine the efficacy and stability of the biodegradable fixation system for treatment of mandible fractures in pediatric patients by measuring the bite force. Methods Sixty pediatric patients with mandibular fractures (36 males, 24 females) were included in this study. The 2.5-mm resorbable plates were adapted along Champy's line of ideal osteosynthesis and secured with four 2.5 mm diameter monocortical resorbable screws, 8 mm in length. All patients were followed for 10 months. Clinical parameters, such as soft tissue infection, nonunion, malunion, implant exposure, malocclusion, nerve injury, and bite force for stability, were prospectively assessed. Results Adequate fixation and primary bone healing was achieved in 100% of the cases. Six minor complications (10%) were observed: 2 soft tissue infections (3%), 1 plate dehiscence (2%), 1 malocclusion (2%), and 2 paresthesia (3%). Conclusion 2.5-mm resorbable plating system along Champy's line of ideal osteosynthesis is a good treatment modality for mandible fractures in pediatric patients. PMID:27195206

Hybrid fixation in the bilateral sagittal split osteotomy for lower jaw advancement

Felipe Ladeira Pereira

2010-02-01

Full Text Available Miniplate and screw fixation has been widely used in bilateral sagittal split osteotomy, but some issues remain unclear concerning its lack of rigidity when compared to Spiessl's bicortical technique. This paper demonstrates the hybrid fixation technique in a case report. A 34-year-old female patient underwent a double jaw surgery with counter-clockwise rotation of the mandible fixed using the hybrid fixation technique. The patient evolved well in the postoperative period and is still under follow up after 14 months, reporting satisfaction with the results and no significant deviation from the treatment plan up to now. No damage to tooth roots was done, maxillomandibular range of motion was within normality and regression of the inferior alveolar nerve paresthesia was observed bilaterally. The hybrid mandibular fixation is clearly visible in the panoramic and cephalometric control radiographs. It seems that the hybrid fixation can sum the advantages of both monocortical and bicortical techniques in lower jaw advancement, increasing fixation stability without significant damage to the mandibular articulation and the inferior alveolar nerve. A statistical investigation seems necessary to prove its efficacy.

Monoclonal IgM anti-myelin-associated glycoprotein (MAG) antibody-related peripheral neuropathy (anti-MAG neuropathy) is predominantly a demyelinating sensory neuropathy with ataxia and distal paresthesia. The clinical course of anti-MAG neuropathy is usually slowly progressive making difficult the identification of clear criteria to start a specific treatment. Although no consensus treatment is yet available, a rituximab-based regimen targeting the B-cell clone producing the monoclonal IgM may be proposed, alone or in combination with alkylating agents or purine analogs. However, in some rare cases, an acute and severe neurological deterioration can occur in few days leading to a rapid loss of autonomy. In these cases, a treatment rapidly removing the monoclonal IgM from the circulation might be useful before initiating a specific therapy. We report successful treatment with plasma exchanges (PE) in four patients presenting with acute neurological deterioration. PE allowed a dramatic and rapid neurological improvement in all patients. PE are safe and may be useful at the initial management of these cases of anti-MAG neuropathy.

Basilar migraine is a complicated headache which the International Headache Society describes as 'migraine with aura symptoms clearly originating from the brainstem or from both occipital lobes'. For years this headache was thought to originate from a transient disturbance in the vertebrobasilar circulation, but more recent studies suggest that a central neuronal disorder may be the source of migraine. Basilar migraines may have certain symptoms which are similar to other neurologic, vascular, psychiatric and metabolic diseases, yet there are specific criteria which can help differentiate it from other diagnoses. It is characterized by a throbbing occipital headache which may be preceded by an aura. The unusual symptoms of basilar migraine, which may precede and continue throughout the duration of the headache and even after it, include bilateral visual symptoms, altered mental status, vertigo, gait ataxia, bilateral paresthesia, bilateral paralysis and dysarthria. We describe a 29-year-old black female whose husband brought her to the emergency department complaining of confusion, headache, and left-sided weakness for 2 h prior to arrival.

Brachial branches of the medial antebrachial cutaneous nerve: A case report with its clinical significance and a short review of the literature

2016-01-01

Full Text Available The medial antebrachial cutaneous nerve (MACN is a branch of the brachial plexus with a great variation within its branches. Knowledge of these variations is critical to neurologists, hand surgeons, plastic surgeons, and vascular surgeons. The aim of this study was to search for variations of the MACN and to discuss their clinical significance. For this study, six arm cadavers from three fresh cadavers were dissected and examined to find and study possible anatomical variations of the MACN. The authors report a rare case of a variation of the MACN, in which there are four brachial cutaneous branches, before the separation to anterior (volar and posterior (ulnar branch, that provide sensory innervation to the medial, inferior half of the arm, in the area that is commonly innervated from the medial brachial cutaneous nerve. To our knowledge, this is the first documented case of this nerve variation. This variation should be taken into serious consideration for the differential diagnosis of patients with complaints of hypoesthesia, pain, and paresthesia and for the surgical operations in the medial part of the arm.

Full Text Available Background: Cerebral venous thrombosis (CVT is uncommon after cesarean section. Although it can be a leading cause of maternal mortality. CVT may occur during pregnancy because of hypercoagulable states such as preeclampsia, thrombophilias, antiphospholipid antibody syndrome and sepsis.Case presentation: A 31 years old woman G2 Ab1 at 37 weeks gestational age with  premature rupture of membrane underwent cesarean section because breech presentation and preeclampsia. Spinal anesthesia was done for emergent cesarean section. On the second day after cesarean section, she developed headache, vomiting, focal neurologic deficits, paresthesia, blurred vision. Brain magnetic resonance imaging (MRI showed thrombosis in anterior half of superior sagittal sinus. Treatment consisted of anticoagulation.  Conclusion: Thrombophilias, pregnancy-related hypertension and cesarean section are the predisposing factors for thromboembolism. Unfractionated heparin and low molecular weight heparin (LMWs are effective drugs for thromboprophylaxis. It is vital to prevent venous thrombosis to reduce mortality during both intrapartum and postpartum periods. Consideration of cerebral venous thrombosis in similar cases is recommended.

High prevalence of Cumulative Trauma Disorders (CTD) of shoulder and wristle among supermarket cashiers have been reported by several studies. To evaluate CTD prevalence in a group of supermarket cashiers in Pisa area is the aim of this study. Standardized Questionnaire and clinical examination have been performed in 128 female supermarket cashiers. In subjects having Symptoms and Signs, Elettroneurography and Echography have been performed. 54 subjects had Paresthesias and performed elettroneurography: 44 (34,4%) had Median nerve impairment at the wrist and among them 37 cases were bilateral; 15 had Ulnar nerve impairment (11,7%), among them 8 were bilateral. Moreover we have performed the echographies in all the 25 subjects with a positive medical examination of the shoulder and they all (19,5% del totale) showed a rotator cuff tendinosis. 25 subjects with CTD (44,6%) showed a comorbidity. An index called BiCo considering both bilaterality and comorbility has been calculated. The percentage of CTD is much more elevated than in general population and many workers present comorbility and bilaterality: a strategy for primary prevention improving ergonomy and information is needed.

Accidental injury of the inferior alveolar nerve due to the extrusion of calcium hydroxide in endodontic treatment: a case report

Directory of Open Access Journals (Sweden)

2016-02-01

Full Text Available During clinical endodontic treatment, we often find radiopaque filling material beyond the root apex. Accidental extrusion of calcium hydroxide could cause the injury of inferior alveolar nerve, such as paresthesia or continuous inflammatory response. This case report presents the extrusion of calcium hydroxide and treatment procedures including surgical intervention. A 48 yr old female patient experienced Calcipex II extrusion in to the inferior alveolar canal on left mandibular area during endodontic treatment. After completion of endodontic treatment on left mandibular first molar, surgical intervention was planned under general anesthesia. After cortical bone osteotomy and debridement, neuroma resection and neurorrhaphy was performed, and prognosis was observed. But no improvement in sensory nerve was seen following surgical intervention after 20 mon. A clinician should be aware of extrusion of intracanal medicaments and the possibility of damage on inferior alveolar canal. Injectable type of calcium hydroxide should be applied with care for preventing nerve injury. The alternative delivery method such as lentulo spiral was suggested on the posterior mandibular molar.

Use of SIG device to accurately place permanent miniature dental implants to retain mandibular overdenture. A case report.

Sussman, Harold I; Goodridge, Opal F

2006-01-01

A case of mini-dental implant insertion for retention of a mandibular overdenture in a hospitalized patient has been documented. The additional use of the SIG (drill guide) directional device in the implant placement protocol gave the practitioner more confidence and resulted in the proper alignment of the three ball-top, one-piece fixtures. The three implants were inserted exactly 1 cm apart and parallel to each other. The distal fixtures were approximately 1 cm away from the mental foramina, thereby eliminating the risk of lip paresthesia. Keeper caps were placed in the denture's intaglio after one month. The keeper caps allowed for proper retention of the overdenture. The caps also enabled the patient to easily insert and withdraw his denture, even though he displayed limited manual dexterity. The tissue response was excellent, and oral hygiene was made easier with adequate spacing of the exposed ball-tops. The overall experience for both the operator and the patient was very positive. General dentists should be able to readily master this technique and add it to their armamentarium for the benefit of all their patients.

The aim of this randomized clinical trial was to assess the efficacy of exclusive lingual nerve block (LNB) in achieving selective lingual soft-tissue anesthesia in comparison with conventional inferior alveolar nerve block (IANB). A total of 200 patients indicated for the extraction of lower premolars were recruited for the study. The samples were allocated by randomization into control and study groups. Lingual soft-tissue anesthesia was achieved by IANB and exclusive LNB in the control and study group, respectively. The primary outcome variable studied was anesthesia of ipsilateral lingual mucoperiosteum, floor of mouth and tongue. The secondary variables assessed were (1) taste sensation immediately following administration of local anesthesia and (2) mouth opening and lingual nerve paresthesia on the first postoperative day. Data analysis for descriptive and inferential statistics was performed using SPSS (IBM SPSS Statistics for Windows, Version 22.0, Armonk, NY: IBM Corp. Released 2013) and a P nerve block in achieving selective anesthesia of lingual soft tissues. It is technically simple and associated with minimal complications as compared to IAN block.

Transient hypoxic respiratory failure in a patient with severe hypophosphatemia.

Oud, Lavi

2009-03-01

Respiratory failure in severely hypophosphatemic patients has been attributed to respiratory muscle weakness, leading to ventilatory failure. While frequently documenting hypercarbic respiratory failure, previous reports of hypophosphatemia-related respiratory failure in patients otherwise free of pulmonary or airway disease often did not provide sufficient information on gas exchange and pulmonary function, precluding inference on alternative or additional sources of respiratory dysfunction in this population. We report a case of acute hypoxic respiratory failure in a 26 year-old bulimic woman with severe hypophosphatemia. The patient presented with acute onset of dyspnea, paresthesias, limb shaking, and severe hyperventilation. SpO2 was 74%, requiring administration of 100% O2, with normal chest radiograph. Serum phosphate was <0.3 mmol/liter (1.0 mg/dL). Further evaluation did not support pulmonary, vascular, neurogenic or external exposure-related causes of hypoxic respiratory failure, which rapidly resolved with parenteral correction of hypophosphatemia. To date, hypoxic respiratory failure has not been reported in association with hypophosphatemia. Increased awareness and further investigations can help elucidate the mechanisms of hypophosphatemia-associated hypoxemia.

There are no published studies on the management of carpal tunnel syndrome (CTS) patients who have already been operated for recurrent CTS on the contralateral side. The aim of this study was to evaluate 13 patients with CTS who underwent primary release using a Canaletto ® implant. The 13 patients had all been operated for recurrent CTS previously. On the contralateral side, they all had subjective signs, and two of them already had complications. All were operated with the Canaletto ® implant according to Duché's technique, in a mean of 20minutes. After a mean 19.3-month follow-up, paresthesia, pain, and QuickDASH scores were significantly improved, even in one patient who underwent revision at another facility. This preliminary study suggests that use of a Canaletto ® implant as first-line treatment for CTS in patients who already underwent revision surgery on the other side is a simple and safe technique, without worsening of symptoms. These findings should be assessed with a prospective randomized controlled trial. Copyright © 2017 SFCM. Published by Elsevier Masson SAS. All rights reserved.

Oral mucositis (OM) is the severe inflammation, lesioning and ulceration of the epithelia, accompanied by bleeding and intensive pain. OM is a common complication of dental implantation. Low-level laser therapy (LLLT) has been found to enhance the repair and healing of epithelia. The aim of this study was to evaluate the effectiveness of preventive and treatment use of LLLT (B-Cure Laser Dental Pro technology in original author's techniques) in the patients who have undergone dental implantation. Simple blind randomized prospective one-center comparative placebo-controlled clinical trial is carried out on the group of 30 partially edentulous patients. It is proved that the use of LLLT before and after installation of dental implants provides: 1) reliable reduction (by 3.5 times) of the frequency of implication and intensity of pain in the first days after operation; 2) reduction (by 3.3-3.7 times) of frequency, duration and intensity of local edematous and inflammatory processes in peri-implant zone and facial soft tissue edema; 3) effective prophylaxis of postoperative sensory, paresthesia and neurologic disturbances in maxillofacial area.

The American College of Surgeons Oncology Group trial Z0011 was a prospective, randomized, multicenter trial comparing overall survival between patients with positive sentinel lymph nodes (SLNs) who did and did not undergo axillary lymph node dissection (ALND). The current study compares complications associated with SLN dissection (SLND) plus ALND, versus SLND alone. From May 1999 to December 2004, 891 patients were randomly assigned to SLND + ALND (n = 445) or SLND alone (n = 446). Information on wound infection, axillary seroma, paresthesia, brachial plexus injury (BPI), and lymphedema was available for 821 patients. Adverse surgical effects were reported in 70% (278 of 399) of patients after SLND + ALND and 25% (103 of 411) after SLND alone (P alone group. At 1 year, lymphedema was reported subjectively by 13% (37 of 288) of patients after SLND + ALND and 2% (six of 268) after SLND alone (P alone. Lymphedema was more common after SLND + ALND but was significantly different only by subjective report. The use of SLND alone resulted in fewer complications.

The authors present 17 cases of malignant neurogenic neoplasms of the head and neck observed in the Department of Otolaryngology in the years 1948-1993. The latest opinions on etiopathology, diagnosis and treatment of these tumors were described. Age and sex of patients, localization of tumor, symptoms histopathology and treatment were analyzed. Progressions of the disease were estimated retrospectively. It has been proved that these tumors develop quickly, give pain and paresthesia. Their diagnosis is very difficult because of their submucosal growth and difficult histopathological interpretation. A characteristic feature of these neurogenic tumors is the ability to give distant metastases. This feature differentiates them from squamous neoplasms, which give mainly nodal metastases. All the patients were subjected to surgery combined with conventional or high voltage radiotherapy. The positive effect of combined chemotherapy in cases of esthesioneuroblastoma is worthy of note. The prognosis in these tumors is often unfavorable. In the group under discussion 13 patients died because of recurrences, two patients are considered to be cured and the remaining 2 patients have had no recurrence for 2 and 3 years. (author)

Title III of the 1990 Clean Air Act Amendments (CAAA) directed the US Environmental Protection Agency (EPA) to evaluate the rate and effect of mercury emissions in the atmosphere and technologies to control the emissions. The US DOE sponsored a risk assessment project at Brookhaven (BNL) to evaluate health risks of mercury emissions from coal combustion. Methylmercury (MeHg) is the compound predominantly responsible for human exposure to atmospheric mercury in the United States, through fish ingestion. In the BNL study, health risks to adults resulting from Hg emissions from a hypothetical coal-fired power plant were estimated using probabilistic risk assessment techniques. This study showed that the effects of emissions of a single large power plant may double the background exposures to MeHg resulting from consuming fish obtained from a localized are near the power plant. Even at these more elevated exposure levels, the attributable incidence in mild neurological symptoms (paresthesia) was estimated to be quite small, especially when compared with the estimated background incidence in the population. 29 refs., 5 figs., 2 tabs.

Full Text Available Restless legs syndrome (RLS is a neurological disorder characterized by uncomfortable sensation of paresthesia in legs that subsequently causes involuntary and continuous movement of the lower limbs, especially at rest. Its prevalence in hemodialysis is more than that in the general population. Different risk factors have been suggested for RLS. We studied the prevalence and risk factors of RLS in 137 hemodialysis patients followed up at our center. The patients completed at least three months on dialysis and fulfilled four criteria for the diagnosis of RLS. We compared the patients with and without RLS, and the odds ratios (ORs were estimated by the logistic regression models. The prevalence of RLS was 36.5% in the study patients. Among the variables, diabetes was the only predicting factor for the development of RLS. The diabetic patients may be afflicted with RLS 2.25 times more than the non-diabetics. Women developed severe RLS 5.23 times more than men. Neurodegeneration, decrease in dopamine level, higher total oxidant status, and neuropathy in diabetic patients may explain the RLS symptoms.

Chronological observation in early radiation myelopathy of the cervical spinal cord; Gadolinium-enhanced MRI findings in two cases

Energy Technology Data Exchange (ETDEWEB)

Hirota, Saeko; Yoshida, Shoji; Soejima, Toshinori (Hyogo Medical Center for Adults, Akashi (Japan)) (and others)

Gd-enhanced MR images of two patients with clinically and histopathologically diagnosed chronic progressive radiation myelitis (CPRM) were observed chronologically. One of them had had nasopharyngeal cancer and received radiotherapy at a dose of 100 Gy to the C1-2 level of the spinal cord. She developed CPRM 25 months after the termination of radiotherapy. The other had had malignant lymphoma originating from the tonsil and received chemoradiotherapy. The dose delivered to her cervical spinal cord was 40 Gy, and she developed CPRM 30 months later. Gd-enhanced MRI in the early phase revealed a small crescent-shaped nidus with or without a very small central nonenhanced area in both cases. Enhancement was not great. At that time, patients noticed only the inability to perceive pain and temperature or paresthesia in the opposite side. In a few months, MRI revealed a much more strongly enhanced and larger nidus with enlargement of a central nonenhanced area accompanied by long segmental cord enlargement. The patients' neurological symptoms had also progressed, with hemiparesis developing, for example. (author).

2015-01-01

Full Text Available Background. Subacute combined degeneration (SCD is a rare cause of demyelination of the dorsal and lateral columns of spinal cord and is a neurogenic complication due to cobalamin deficiency. Anemia of chronic disease (ACD occurs in patients with acute or chronic immune activation, including infective endocarditis. It remains to be elucidated whether ACD patients are more sensitive to suffer from SCD. Little cases about SCD patients accompanied with ACD have been reported till now. Here we reported a 36-year-old man with SCD with a medical history of mitral inadequacy over 20 years, who was admitted and transported from another hospital to our hospital due to an 8-month history of gait disturbance, lower limb weakness and paresthesia, and loss of proprioception. Significant laboratory results and echocardiography suggest iron deficiency anemia and infective endocarditis (IE. The SCD diagnosis was confirmed by MRI, which showed selective demyelination in the dorsal and lateral columns of spinal cord. In conclusion, the ACD patients may suffer from SCD, which can be diagnosed by 3 Tesla magnetic resonance imaging.

1999-12-01

Intracranial involvement by adenoid cystic carcinoma (ACC) is very rare and there is no report of intracranial extension from the palate ACC in Korea. Intracranial involvement can occur in one of three ways: direct extension, perineural spread, and hematogenous spread. A case report of a 35-year-old woman with intracranial ACC is presented. Initially she had ACC of the right palate and was treated by surgery and postoperative radiation therapy. Three years and 10 months later, the paresthesia in the distribution of ophthalmic and maxillary branch of right trigeminal nerve developed without evidence of recurrence in CT scan. Ptosis and total ophthalmoplegia developed sequentially and the second operation was performed. It was suggested that the tumor was spread perineurally along the trigeminal nerve into the Gasserian ganglion and then cavernous sinus and orbit. Seven years and 6 months after the first operation, direct intracranial extension into the right temporal lobe developed via sphenoid bone, sphenoid sinus and temporal bone and the third operation was done. And then Jung metastasis was diagnosed. She is alive for 9 years 5 months after first operation.

Spinal cord injury after conducting transcatheter arterial chemoembolization for costal metastasis of hepatocellular carcinoma

Directory of Open Access Journals (Sweden)

Sang Jung Park

2012-09-01

Full Text Available Transcatheter arterial chemoembolization (TACE has been used widely to treat patients with unresectable hepatocellular carcinoma. However, this method can induce various adverse events caused by necrosis of the tumor itself or damage to nontumor tissues. In particular, neurologic side effects such as cerebral infarction and paraplegia, although rare, may cause severe sequelae and permanent disability. Detailed information regarding the treatment process and prognosis associated with this procedure is not yet available. We experienced a case of paraplegia that occurred after conducting TACE through the intercostal artery to treat hepatocellular carcinoma that had metastasized to the rib. In this case, TACE was attempted to relieve severe bone pain, which had persisted even after palliative radiotherapy. A sudden impairment of sensory and motor functions after TACE developed in the trunk below the level of the sternum and in both lower extremities. The patient subsequently received steroid pulse therapy along with supportive care and continuous rehabilitation. At the time of discharge the patient had recovered sufficiently to enable him to walk by himself, although some paresthesia and spasticity remained.

Evans, R W

1992-11-01

Motor vehicle accidents with a whiplash mechanism of injury are one of the most common causes of neck injuries, with an incidence of perhaps 1 million per year in the United States. Proper adjustment of head restraints can reduce the incidence of neck pain in rear-end collisions by 24%. Persistent neck pain is more common in women by a ratio of 70:30. Whiplash injuries usually result in neck pain owing to myofascial trauma, which has been documented in both animal and human studies. Headaches, reported in 82% of patients acutely, are usually of the muscle contraction type, often associated with greater occipital neuralgia and less often temporomandibular joint syndrome. Occasionally migraine headaches can be precipitated. Dizziness often occurs and can result from vestibular, central, and cervical injury. More than one third of patients acutely complain of paresthesias, which frequently are caused by trigger points and thoracic outlet syndrome and less commonly by cervical radiculopathy. Some studies have indicated that a postconcussion syndrome can develop from a whiplash injury. Interscapular and low back pain are other frequent complaints. Although most patients recover within 3 months after the accident, persistent neck pain and headaches after 2 years are reported by more than 30% and 10% of patients. Risk factors for a less favorable recovery include older age, the presence of interscapular or upper back pain, occipital headache, multiple symptoms or paresthesias at presentation, reduced range of movement of the cervical spine, the presence of an objective neurologic deficit, preexisting degenerative osteoarthritic changes; and the upper middle occupational category. There is only a minimal association of a poor prognosis with the speed or severity of the collision and the extent of vehicle damage.

procedures. Early in the study, heating of the internal capsule resulted in 2 cases (8%) of mild hemiparesis, which improved and prompted monitoring of an additional axis during magnetic resonance thermometry. Other persistent adverse events were orofacial paresthesia (4 events [20%]), finger paresthesia (1 event [5%]), and ataxia (1 event [5%]). Focused ultrasound thalamotomy for patients with TDPD demonstrated improvements in medication-refractory tremor by CRST assessments, even in the setting of a placebo response.

This retrospective case study analysed the incidence and symptoms of ciguatera fish poisoning (ciguatera) in Guadeloupe (French West Indies) between 2013 and 2016. Cases attending the emergency departments of the two public hospitals and the reports received by the regional health authority in charge of monitoring (ARS) were compiled. Two hundred and thirty-four cases of poisoning were observed, with a mean annual incidence of 1.47/10,000 (95% CI): 1.29-1.66), i.e 5 times higher than the previously reported incidence (1996-2006). The main species described as being responsible for poisoning were fish from the Carangidae family (n = 47) (jack), followed by fish from the Lutjanidae family (n = 27) (snapper), Serranidae family (n = 15) (grouper), Sphyraenidae family (n = 12) (barracuda), and Mullidae family (n = 12) (goatfish). One case of lionfish ciguatera was observed. 93.9% of patients experienced gastrointestinal symptoms, 76.0% presented neurological signs (mainly paresthesia, dysesthesia and pruritus) and 40.3% presented cardiovascular symptoms (bradycardia and/or hypotension). A high frequency (61.4%) of hypothermia (body temperature ciguatera poisoning throughout the Caribbean region must be improved, notably after reef disturbance due to Irma and Maria major cyclones.

Purpose: To evaluate the incidence and causes of complications associated with balloon-occluded arterial infusion chemotherapy (BOAI) for pelvic malignancies. Methods: In 34 courses of BOAI in 22 patients with pelvic malignancies, we analyzed the incidence of complications as well as the effect of the dose of the anticancer drugs, the infusion site, and the number of BOAI administrations on these complications. Complications were divided into two categories: cystitis-like symptoms and neurological complications such as pain, numbness, and paresthesia of the lower extremities and the hip. Results: Eleven patients (50%) suffered from complications, seven (31.8%) from neurological complications and four (18.2%) from cystitis-like symptoms. The complications appeared in 14 courses (42.4%) of BOAI, neurological complications in 10 (30.3%) and cystitis-like symptoms in four (12.1%). A high dose of anti-cancer drugs and infusion from the anterior division tended to induce neurological complications more frequently; however, the cystitis-like symptoms were not related to any factors. Conclusion: Our results indicate that a smaller dose of anti-cancer drugs should be infused from the bilateral internal iliac arteries for safer pelvic BOAI

Full Text Available Abstract Introduction Intracranial schwannomas unrelated to the cranial nerves are uncommon. We report a new case of tentorial schwannoma unrelated to the cranial nerves, with extension into the pons. A literature review with discussion of the most relevant pathogenetic aspects is also performed. Case presentation A 42-year-old Caucasian man was admitted with right-sided paresthesias and weakness of his upper and lower extremities. The neurological examination revealed right hemiparesis and hemi-hypoesthesia. A brain magnetic resonance imaging scan revealed a cerebellopontine lesion, arising from the left free edge of the tentorium, and extending into his pons. A piecemeal removal was performed through a retrosigmoid approach. The lesion was not found to be associated with any cranial nerves. The histological examination revealed a schwannoma Antoni type A. His postoperative course was uneventful. At one year follow-up, the patient was neurologically intact and the magnetic resonance imaging of his brain performed at that time showed complete removal without signs of recurrence. Conclusion Tentorial schwannomas are rare clinical entities. Knowledge of their clinical, radiological and anatomical characteristics is very important for the correct diagnosis and management.

Anti-Myelin oligodendrocyte glycoprotein (MOG) antibodies are detected in various demyelinating diseases, such as pediatric acute disseminated encephalomyelitis (ADEM), recurrent optic neuritis, and aquaporin-4 antibody-seronegative neuromyelitis optica spectrum disorder. We present a patient who developed anti-MOG antibody-positive ADEM following infectious mononucleosis (IM) due to Epstein-Barr virus (EBV) infection. A 36-year-old healthy man developed paresthesia of bilateral lower extremities and urinary retention 8 days after the onset of IM due to primary EBV infection. The MRI revealed the lesions in the cervical spinal cord, the conus medullaris, and the internal capsule. An examination of the cerebrospinal fluid revealed pleocytosis. Cell-based immunoassays revealed positivity for anti-MOG antibody with a titer of 1:1024 and negativity for anti-aquaporin-4 antibody. His symptoms quickly improved after steroid pulse therapy followed by oral betamethasone. Anti-MOG antibody titer at the 6-month follow-up was negative. This case suggests that primary EBV infection would trigger anti-MOG antibody-positive ADEM. Adult ADEM patients can be positive for anti-MOG antibody, the titers of which correlate well with the neurological symptoms.

Postherpetic neuralgia (PHN) is often refractory to existing treatments. Treatment of the dorsal root ganglion (DRG) using monopolar pulsed radiofrequency (PRF), which is a non- or minimally neurodestructive technique, is not efficacious in all patients. This study aimed to determine the safety and clinical efficacy of bipolar high-voltage, long-duration PRF on the DRG in PHN patients. Self before-after controlled clinical trial. Department of Pain Medicine, the First Affiliated Hospital of China Medical University. Ninety patients diagnosed with PHN for > 3months were included. Bipolar high-voltage, long-duration PRF at 42°C for 900 seconds was applied after the induction of paresthesias covered the regions of hyperalgesic skin. The therapeutic effects were evaluated using a visual analog scale (VAS) and the 36-item Short Form health survey (SF-36) before treatment and one, 4, 8, and 12 weeks after PRF. The VAS scores at one, 4, 8, and 12 weeks after PRF treatment were significantly lower than before treatment (P DRG is an effective and safe therapeutic alternative for PHN patients. This treatment could improve the quality of life of PHN patients. NO ChiCTR-OCS-14005461.

Neurological manifestations of Ehlers-Danlos syndrome(s): A review

Castori, Marco; C. Voermans, Nicol

2014-01-01

The term “Ehlers-Danlos syndrome” (EDS) groups together an increasing number of heritable connective tissue disorders mainly featuring joint hypermobility and related complications, dermal dysplasia with abnormal skin texture and repair, and variable range of the hollow organ and vascular dysfunctions. Although the nervous system is not considered a primary target of the underlying molecular defect, recently, increasing attention has been posed on neurological manifestations of EDSs, such as musculoskeletal pain, fatigue, headache, muscle weakness and paresthesias. Here, a comprehensive overview of neurological findings of these conditions is presented primarily intended for the clinical neurologist. Features are organized under various subheadings, including pain, fatigue, headache, stroke and cerebrovascular disease, brain and spine structural anomalies, epilepsy, muscular findings, neuropathy and developmental features. The emerging picture defines a wide spectrum of neurological manifestations that are unexpectedly common and potentially disabling. Their evaluation and correct interpretation by the clinical neurologist is crucial for avoiding superfluous investigations, wrong therapies, and inappropriate referral. A set of basic tools for patient’s recognition is offered for raising awareness among neurologists on this underdiagnosed group of hereditary disorders. PMID:25632331

Levine, Adrian B; Parrent, Andrew G; MacDougall, Keith W

2017-01-01

Spinal cord stimulation (SCS) is a well-established treatment for chronic neuropathic pain in the lower limbs. Upper limb pain comprises a significant proportion of neuropathic pain patients, but is often difficult to target specifically and consistently with paresthesias. We hypothesized that the use of dorsal nerve root stimulation (DNRS), as an option along with SCS, would help us better relieve pain in these patients. All 35 patients trialed with spinal stimulation for upper limb pain between July 1, 2011, and October 31, 2013, were included. We performed permanent implantation in 23/35 patients based on a visual analogue scale pain score decrease of ≥50% during trial stimulation. Both the SCS and DNRS groups had significant improvements in average visual analogue scale pain scores at 12 months compared with baseline, and the majority of patients in both groups obtained ≥50% pain relief. The majority of patients in both groups were able to reduce their opioid use, and on average had improvements in Short Form-36 quality of life scores. Complication rates did not differ significantly between the two groups. Treatment with SCS or DNRS provides meaningful long-term relief of chronic neuropathic pain in the upper limbs.

Every year, 240,000 people are struck by lightning worldwide, causing injuries leading to significant handicaps. Most of the symptoms involve brain lesions; neuromuscular sequelae and myelopathy are less common. We describe five cases of patients struck by lightning with various clinical presentations. The first patient presented painful paresthesias in both upper limbs that disappeared 18 months later; the injury was a plexopathy. The second patient developed proximal weakness in the upper-left limb due to a myopathy. Two patients presented with various motor weaknesses in the lower limbs due to motor neuron disease and myelopathy. The last patient had a transient tetraplegy, which resolved in 5minutes; the diagnosis was keraunoparalysis. Lightning injuries can have many consequences depending on the different mechanisms involved. The clinical presentation is often due to a very focal lesion without any secondary extension. Motor neuron disease probably results from post-traumatic myelopathy. We discuss the ALS-electrocution association, frequently described in the literature. Various peripheral nerve and spinal cord lesions can be seen in lightning strike victims involving myelopathy, motor neuron, muscle and plexus. Clinical syndromes are often atypical but outcome is often favorable. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

2017-01-01

Trigeminal trophic syndrome (TTS) is an uncommon disorder of the trigeminal nerve tract and trigeminal brainstem nucleus. The syndrome is characterized by a triad of unilateral crescentic ulcers with anesthesia and paresthesias of the involved trigeminal dermatomes. A 24-year-old right-handed black female presented to our emergency department with a 4-week history of rapidly progressive painless desquamation/denudation of skin over her right face and scalp. Four weeks prior, she had been admitted to another institution for seizures and was diagnosed with seizures provoked by synthetic marijuana use. She was afebrile during her initial presentation at our institution. Dermatologic examination revealed denudation of the epidermis and partial dermis over the right frontal, parietal, and temporal scalp with associated alopecia. To our knowledge, the association of disorders of the trigeminal nerve pathway, including TTS, with the use of synthetic marijuana has not been previously reported. The long-term neurologic effects of synthetic marijuana are difficult to predict, and the pathologic underpinnings of TTS are largely unknown. Further studies dedicated to exploring the underlying molecular and cellular mechanisms may translate into effective therapies and approaches to halt and reverse the process and prevent tissue destruction and cosmetic disfigurement.

Full Text Available Background: Chronic low back pain is among a wide spread musculoskeletal conditions that is related to disability with high economy cost. There are several treatment modalities for controlling chronic low back pain (CLBP, among them high intensity laser therapy (HILT and epidural blocks (EB use more commonly. This study aimed to evaluate the benefits and hazards of each of these two methods.Materials and Methods: We designed a randomized controlled double blind study during 24 months.101 patients divided in 2 groups (52 in EB and 49 in HILT group. Pain intensity was assessed by using faces pain scales (FPS and LINKERT questionaries' before procedure and during one, four, 12, and 24 weeks after beginning the procedures.Results: There were no differences between two groups in FPS lumber tenderness, straight leg rising test (SLRT, paresthesia, deep tendon reflex (DTR, and imaging changes. Motor problems seem was less in HILT group comparing EB.Conclusion: This study showed both EB and HILT approaches can control the pain intensity and motor activities in CLBP patients. Future studies will clarify the precise importance of each these methods.

Post-finasteride syndrome and post-SSRI sexual dysfunction: two sides of the same coin?

2018-04-19

Sexual dysfunction is a clinical condition due to different causes including the iatrogenic origin. For instance, it is well known that sexual dysfunction may occur in patients treated with antidepressants like selective serotonin reuptake inhibitors (SSRI). A similar side effect has been also reported during treatment with finasteride, an inhibitor of the enzyme 5alpha-reductase, for androgenetic alopecia. Interestingly, sexual dysfunction persists in both cases after drug discontinuation. These conditions have been named post-SSRI sexual dysfunction (PSSD) and post-finasteride syndrome (PFS). In particular, feeling of a lack of connection between the brain and penis, loss of libido and sex drive, difficulty in achieving an erection and genital paresthesia have been reported by patients of both conditions. It is interesting to note that the incidence of these diseases is probably so far underestimated and their etiopathogenesis is not sufficiently explored. To this aim, the present review will report the state of art of these two different pathologies and discuss, on the basis of the role exerted by three different neuromodulators such as dopamine, serotonin and neuroactive steroids, whether the persistent sexual dysfunction observed could be determined by common mechanisms.

Full Text Available We analyzed 37 patients who underwent segmental wide resection of bone tumors and reconstruction with a modular titanium endoprosthesis at the Orthopaedic Oncology Group, between 1992 and 1998. Twelve patients were male and 25 were female, with a mean age of 30 years (9 - 81. The mean follow-up was 14 months (2 - 48. The diagnoses were: osteosarcoma (14 cases, metastatic carcinoma (10, Ewing's sarcoma (4, giant cell tumor (4, malignant fibrous histiocytoma (3, chondrosarcoma (1, and aneurysmal bone cyst (1. Eleven articulated total knee, 8 partial proximal femur with bipolar acetabulum, 8 partial proximal humerus, 3 total femur, 2 partial proximal tibia, 2 diaphyseal femur, 2 diaphyseal humerus, and 1 total proximal femur with cementless acetabulum endoprosthesis implant procedures were done. The complications related to the procedure included: infection (5 cases, dislocation (3, module loosening (1, and ulnar nerve paresthesia (1. We used the following criteria for the clinical evaluation: presence of pain, range of motion, reconstruction stability, surgical and oncologic complications, and patient acceptance. The results were good in 56.8% of the cases, regular in 32.4% and poor in 10.8%.

To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far. Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4. All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years. This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

Although thalamic deep brain stimulation (DBS) has been established as an effective therapy for refractory tremor in Parkinson's disease and essential tremor, reports investigating the efficacy of posterior subthalamic area (PSA) DBS for severe, debilitating tremors continue to emerge. However, questions regarding the optimal anatomical target, surgical approach, programming paradigms and effectiveness compared to other targets remain. In this report, we aimed to review the current literature to assess different stereotactic techniques, anatomical considerations, adverse effects and stimulation settings in PSA DBS. A comprehensive literature review was performed searching for articles discussing tremors and PSA stimulation. We performed a quantitative analysis comparing different DBS tremor targets. Tremor improvement is consistently documented in most reports with an average reduction in tremor of 79% depending on the specific tremor syndrome. Tremor benefit in patients with multiple sclerosis (MS) tremor was significantly higher than for other stimulation targets. Transient paresthesias, imbalance, dizziness and dysarthria are the most common side effects with PSA DBS. PSA DBS is an effective and safe treatment for tremor control and should be considered in patients with refractory tremors with associated cerebellar or dystonic features, proximal tremors and MS tremor. © 2016 S.

1982-04-01

CT findings of meningeal carcinomatosis were studied in 17 patients (seven with lung cancer, two with breast cancer, one with gastric cancer, one with malignant melanoma, five with leukemia, and one with malignant lymphoma). The diagnosis was confirmed by a cytological survey of the cerebrospinal fluid and/or autopsy. Signs and symptoms caused by meningeal carcinomatosis at the CT examination varied from individual to individual. Those most frequently observed were signs of increased intracranial pressure, often accompanied by cranial nerve palsies, paresthesia, motor weakness, cerebellar signs, and nuchal stiffness, CT scan revealed evidence of meningeal carcinomatosis in ten cases out of the seventeen. CT evidences were obtained in 16.7% of the cases with hematologic malignancy and in 81.8% of those with non-hematologic malignancies. The CT findings of meningeal carcinomatosis may be summarized as follows: I. 1) Obliteration and narrowing of the cisterns and sulci, with contrast enhancement along them. 2) Enhanced spots/areas beneath the brain surface, with contrast enhancement. 3) Diffuse, slightly high density of the brain surface, with contrast enhancement. 4) Enhancement of the ventricular wall. 5) Hydrocephalus. II. 1) No CT abnormalities.

Full Text Available Numb chin syndrome (NCS is characterized by facial neuropathy along the distribution of the mental branch of the trigeminal nerve. We report a case of NCS in a 65 year old woman who initially presented to her dentist with nonspecific symptoms that she thought were related to a tooth infection. The patient was otherwise healthy and her medical history was significant for breast cancer treated 20 years prior; her cancer was thought to be in complete remission. Upon clinical examination and conventional dental radiography, no pathology was seen such as odontogenic, periodontal, or jawbone infection. Only paresthesia and hypoesthesia was noted unilaterally in her left chin, jaw and lower lip. A computed tomography scan was obtained for further evaluation and revealed lytic metastatic disease involving the right mandible at the level of the mandibular foramen; lytic lesions of the thoracic vertebrae and multiple pulmonary nodules were also noted. Oncologic referral was made immediately which confirmed a diagnosis of metastatic breast cancer. Familiarity with NCS is important for oral health care providers in order to identify etiology and differential diagnosis, as well as to provide appropriate referral and management.

Sacroiliac joint (SIJ) can cause low back pain when its joint capsule and ligamentous tissue are damaged. We report our experience in treating three SIJ dysfunction patients presenting with acute low back pain (a 38 year-old male, a 24 year-old male, and a 32 year-old female). SIJ dysfunction was diagnosed using the one-finger test, the modified Newton test, and SIJ injection. In all three patients, lumbar MRI demonstrated slightly degenerated lumbar lesions (lumbar canal stenosis, lumbar disc hernia). Two patients had paresthesia or pain in the leg and all three patients showed iliac muscle tenderness in the groin, which was thought to be a referred symptom because of improvement after SIJ injection. The two male patients returned to work and the problems have not recurred. Although our female patient resumed daily life as a housewife, her condition recurred at intervals of 2-3 months and she required regular SIJ injections. The prevalence of SIJ dysfunction of low back pain is about 10%, so it should be considered as a differential diagnosis when treating low back pain and designing treatment for lumbar spinal disorders.

An outbreak of unexplained and severe kidney disease, "Mesoamerican Nephropathy," in mostly young, male sugar cane workers emerged in Central America in the late 1990's. As a result, an estimated 20,000 individuals have died, to date. Unfortunately, and with great consequence to human life, the etiology of the outbreak has yet to be identified. The sugarcane fields in Chichigalpa, Chinandega, Nicaragua, have been involved in the outbreak, and during our initial investigation, we interviewed case patients who experienced fever, nausea and vomiting, arthralgia, myalgia, headache, neck and back pain, weakness, and paresthesia at the onset of acute kidney disease. We also observed a heavy infestation of rodents, particularly of Sigmodon species, in the sugarcane fields. We hypothesize that infectious pathogens are being shed through the urine and feces of these rodents, and workers are exposed to these pathogens during the process of cultivating and harvesting sugarcane. In this paper, we will discuss the epidemic in the Chichigalpa area, potential pathogens responsible for Mesoamerican Nephropathy, and steps needed in order to diagnose, treat, and prevent future cases from occurring.

1982-01-01

Thirty-three patients with grade III and IV supratentorial astrocytomas who were entered into a radomized two-arm study to evaluate the effect of misonidazole in conjunction with postoperative irradiation are available for analysis. All patients received the same radiation dose: 6650 rads (43 MeV photons) in 31 fractions over 7 1/2 weeks. Misonidazole was given orally 4 to 5 hours before irradiation on those treatment days when fractional radiation doses of 400 rads were used. The cumulative dose of misonidazole was 27 g, corresponding to 12.6 to 16.4 g/m 2 . With a minimum follow-up time of one year, median survival for patients receiving postoperative irradiation had a median survival of 57.1 weeks. The difference in the distribution of survival times between both groups is statistically significant (p < 0.02). From an analysis of variance for age, it cannot be ruled out that the survival difference between the two groups is at least partly due to differences in ages. Side effects of misonidazole were minimal, with only 2 patients experiencing mild paresthesias and 4 noting a transient tinnitus

Surface electrical stimulation (SES) is being investigated as a noninvasive method to evoke natural sensations distal to electrode location. This may improve treatment for phantom limb pain as well as provide an alternative method to deliver sensory feedback. The median and/or ulnar nerves of 35 subjects were stimulated at the elbow using surface electrodes. Strength-duration curves of hand sensation were found for each subject. All subjects experienced sensation in their hand, which was mostly described as a paresthesia-like sensation. The rheobase and chronaxie values were found to be lower for the median nerve than the ulnar nerve, with no significant difference between sexes. Repeated sessions with the same subject resulted in sufficient variability to suggest that recalculating the strength-duration curve for each electrode placement is necessary. Most of the recruitment curves in this study were generated with 28 to 36 data points. To quickly reproduce these curves with limited increase in error, we recommend 10 data points. Future studies will focus on obtaining different sensations using SES with the strength-duration curve defining the threshold of the effective parameter space.

To investigate the influence of the local sensory abnormality in throat while the change of motility in the upper esophageal sphincter (UES) and lower esophageal sphincter (LES), as well as the change of esophageal body in pharyngeal paraesthesia. From January 2014 to January 2015 there were sixty-four patients who had pharyngeal susceptible syndrome (PSS) but without confirmed organic disease were enrolled as the PSS group, forty healthy volunteers as the control group. High resolution manometry (HRM) was utilized to distinguish esophageal motility patterns of PSS, including the muscular tension of LES and UES, the integrity, adaptability, amplitude, speed and duration of esophageal peristalsis at 10 swallows. The resting LES and UES pressures and the distal contractile integral (DCI) of esophagus in PSS group were lower than that in control group (P 0.05). The average peak pressure was similar in two groups (P > 0.05). Muscle tension around the UES has no obvious change when pharyngeal paraesthesia occurred, but the reduction of esophageal motor function, clearance ability, anti-reflux gastroesophageal junction, causing the abnormal reflux which hurt the pharyngeal surface mucosa maybe one of the most important reasons leading to pharyngeal paresthesia.

Periosteal chondroma is a very unusual cartilaginous neoplasm of the spinal canal. We herein report a case of periosteal chondroma in a 41-year-old male who presented with gait disturbance and paresthesia of both lower extremities. Magnetic resonance (MR) images showed an extradural mass which caused compression of the spinal cord at the T5/6 level. The mass showed iso-signal intensity on T1-weighted images, high signal intensity on T2-weighted images, and nodular and peripheral rim enhancement on post-contrast T1-weighted images. Computed tomography (CT) images showed a mass with punctate calcifications and extension into the left T5/6 neural foramen. MR and CT images showed extrinsic cortical bone erosion of the posterior inferior body of T5 and superior pedicle of T6, bone remodeling with overhanging margins, and sclerosis adjacent to the tumor. The patient underwent a complete excision of the mass by left T5/6 hemi-laminectomy and exhibited complete resolution of his symptoms. Histopathologic examination revealed periosteal chondroma. Tumor recurrence was not recorded during the 18-month follow-up period. (orig.)

Full Text Available Introduction: VZV is an exclusively human pathogen. The primary infection typically occurs during childhood and causes varicella. As with other members of the herpes viruses’ family, VZV is noninfectious in its latent form but can reactivate at a later time to form intact virions in the involved sensory neurons. These virions then migrate to the skin through axons, spread from cell to cell, and penetrate the epidermis.Case Report: In this case a 72 years old woman with history of diabetes mellitus and hypertension is reported hospitalized because of urinary retention, weakness and parestesia in the right leg, complicated with vesiculoulcerative lesions in sacral area with distribution to the right buttock and vagina. L.P was done to confirm inflammatory radicopathy that showed aseptic meningitis and therapy started with acyclovir and prednisolone. Patient got well and discharged from the hospital.Conclusion: Motor weakness in noncranial nerve is one of the zoster complications known as zoster paresis. Weakness begins suddenly 2-3 weeks after rash and progresses to extremities. In this case 3 weeks after rash, nerve complications were observed. We recommend to do paresthesia examination of skin for eruption in all patients presented with paresis.

To analyze the nosazontology of pharyngeal paraesthesia and investigate the treatment. Two hundred and twelve misdiagnosed pharyngeal paraesthesia patients were investigated by history inquiry, routine examination, 24-hour esophageal pH monitoring, barium X-ray of the oesophagus, anxieties-athymic private measuring scale, coefficient of variation of the R-R (CVR-R), bioavailable testosterone detection (Bio-T), erection experiment and questionnaire about man climacteric syndrome. The concomitant symptoms and positions of pharyngeal paresthesia were also studied. We adopted individuallized sequential multi-therapy for every patient according to the cause of disease. The cause of disease within 212 cases of pharyngeal paraesthesia included 62 psychic trauma, 32 endocrine system disease, 106 upper gastrointestinal disease, circulatory disease, 9 circulatory disease, 3 idiopathic. With individualized treatment, 110 cases had fully recovered, 63 cases excellence and 31 cases utility, and the efficiency rate was 96.23%. Pharyngeal paraesthesia can be caused by several factors. Thorough examination and comprehensive analysis should be applied to those incurable patient who has been treated for a long time. Short course of treatment and irrational drug use are the main causes of short-term recurrence and unsatisfactory curative effect.

CT findings of meningeal carcinomatosis were studied in 17 patients (seven with lung cancer, two with breast cancer, one with gastric cancer, one with malignant melanoma, five with leukemia, and one with malignant lymphoma). The diagnosis was confirmed by a cytological survey of the cerebrospinal fluid and/or autopsy. Signs and symptoms caused by meningeal carcinomatosis at the CT examination varied from individual to individual. Those most frequently observed were signs of increased intracranial pressure, often accompanied by cranial nerve palsies, paresthesia, motor weakness, cerebellar signs, and nuchal stiffness, CT scan revealed evidence of meningeal carcinomatosis in ten cases out of the seventeen. CT evidences were obtained in 16.7% of the cases with hematologic malignancy and in 81.8% of those with non-hematologic malignancies. The CT findings of meningeal carcinomatosis may be summarized as follows: I. 1) Obliteration and narrowing of the cisterns and sulci, with contrast enhancement along them. 2) Enhanced spots/areas beneath the brain surface, with contrast enhancement. 3) Diffuse, slightly high density of the brain surface, with contrast enhancement. 4) Enhancement of the ventricular wall. 5) Hydrocephalus. II. 1) No CT abnormalities. (author)

The authors present 17 cases of malignant neurogenic neoplasms of the head and neck observed in the Department of Otolaryngology in the years 1948-1993. The latest opinions on etiopathology, diagnosis and treatment of these tumors were described. Age and sex of patients, localization of tumor, symptoms histopathology and treatment were analyzed. Progressions of the disease were estimated retrospectively. It has been proved that these tumors develop quickly, give pain and paresthesia. Their diagnosis is very difficult because of their submucosal growth and difficult histopathological interpretation. A characteristic feature of these neurogenic tumors is the ability to give distant metastases. This feature differentiates them from squamous neoplasms, which give mainly nodal metastases. All the patients were subjected to surgery combined with conventional or high voltage radiotherapy. The positive effect of combined chemotherapy in cases of esthesioneuroblastoma is worthy of note. The prognosis in these tumors is often unfavorable. In the group under discussion 13 patients died because of recurrences, two patients are considered to be cured and the remaining 2 patients have had no recurrence for 2 and 3 years.

The clinical and neurophysiological characteristics of radiation-induced brachial plexopathy (RBP) were assessed in 79 breast cancer patients without signs of recurrent disease at least 60 months after radiotherapy (RT). Clinically, 35% (95% confidence limits: 25-47%) had RBP. Fifty percent (31-69%) had affection of the entire plexus, 18% (7-36%) of the upper trunk only, and 4% (1-18%) of the lower trunk. In 28% (14-48%), assessment of a definite level was not possible. In most, symptoms began during or immediately after RT, thus being without significant latency. Numbness or paresthesias (71%, 52-86%) and pain (43%, 25-62%) were the most prominent symptoms, while the most prominent objective signs were decreased or absent muscle stretch reflexes (93%, 77-99%) closely followed by sensory loss (82%, 64-93%) and weakness (71%, 52-86%). Neurophysiological investigations were carried out in 46 patients (58%). The most frequent abnormalities in patients with RBP were signs of chronic partial denervation with increased mean duration of individual motor unit potentials, and decreased amplitude of compound muscle and sensory action potentials. Nerve conduction velocities were normal. (author)

Full Text Available Palytoxin (PLTX, one the most potent marine toxins, and/or its analogs, have been identified in different marine organisms, such as Palythoa soft corals, Ostreopsis dinoflagellates, and Trichodesmium cyanobacteria. Although the main concern for human health is PLTXs entrance in the human food chain, there is growing evidence of adverse effects associated with inhalational, cutaneous, and/or ocular exposure to aquarium soft corals contaminated by PLTXs or aquaria waters. Indeed, the number of case reports describing human poisonings after handling these cnidarians is continuously increasing. In general, the signs and symptoms involve mainly the respiratory (rhinorrhea and coughing, skeletomuscular (myalgia, weakness, spasms, cardiovascular (electrocardiogram alterations, gastrointestinal (nausea, and nervous (paresthesia, ataxia, tremors systems or apparates. The widespread phenomenon, the entity of the signs and symptoms of poisoning and the lack of control in the trade of corals as aquaria decorative elements led to consider these poisonings an emerging sanitary problem. This review summarizes literature data on human poisonings due to, or ascribed to, PLTX-containing soft corals, focusing on the different PLTX congeners identified in these organisms and their toxic potential.

Full Text Available Bortezomib, an effective anticancer drug for multiple myeloma, often causes peripheral neuropathy which is mainly characterized by numbness and painful paresthesia. Nevertheless, there is no effective strategy to escape or treat bortezomib-induced peripheral neuropathy (BIPN, because we have understood few mechanism of this side effect. In this study, we evaluated behavioral and pathological characteristics of BIPN, and investigated pharmacological efficacy of various analgesic drugs and adjuvants on mechanical allodynia induced by bortezomib treatment in rats. The repeated administration of bortezomib induced mechanical and cold allodynia. There was axonal degeneration of sciatic nerve behind these neuropathic symptoms. Furthermore, the exposure to bortezomib shortened neurite length in PC12 cells. Finally, the result of evaluation of anti-allodynic potency, oral administration of tramadol (10 mg/kg, pregabalin (3 mg/kg, duloxetine (30 mg/kg or mexiletine (100 mg/kg, but not amitriptyline or diclofenac, transiently relieved the mechanical allodynia induced by bortezomib. These results suggest that axonal degeneration of the sciatic nerve is involved in BIPN and that some analgesic drugs and adjuvants are effective in the relief of painful neuropathy.

Full Text Available Complex regional pain syndrome (CRPS is a disease with unclear pathophysiology. The condition is characterized by pain, soft tissue change, vasomotor change, and even psychosocial disturbance. It may affect the upper more than the lower extremities, and the distal more than the proximal. The trigger factors include carpal tunnel release, Dupuytren's repair, tendon release procedures, knee surgery, crush injury, ankle arthrodesis, amputation, and hip arthroplasty. Rarely, it has been associated with stroke, mastectomy, pregnancy, and osteogenesis imperfecta. Herein, we present a rare case of a patient who was diagnosed with CRPS after transradial cardiac catheterization. CRPS was first diagnosed due to hand swelling, allodynia, paresthesia, and the limited range of motion of interphalangeal, metacarpophalangeal, and wrist joints, with the preceding factor of transradial cardiac catheterization, and was then confirmed by a three-phase bone scan. After intensive physical therapy with hydrotherapy, manual soft tissue release, and occupational therapy for the hand function, there was much improvement in range of motion and hand function. There was no allodynia or painful sensation in the follow-up. After training, the functional status of this patient was adequate for daily activity.

Perspectives on the Role of Fospropofol in the Monitored Anesthesia Care Setting

Full Text Available Monitored anesthesia care (MAC is a safe, effective, and appropriate form of anesthesia for many minor surgical procedures. The proliferation of outpatient procedures has heightened interest in MAC sedation agents. Among the most commonly used MAC sedation agents today are benzodiazepines, including midazolam, and propofol. Recently approved in the United States is fospropofol, a prodrug of propofol which hydrolyzes in the body by alkaline phosphatase to liberate propofol. Propofol liberated from fospropofol has unique pharmacological properties, but recently retracted pharmacokinetic (PK and pharmacodynamic (PD evaluations make it difficult to formulate clear conclusions with respect to fospropofol's PK/PD properties. In safety and efficacy clinical studies, fospropofol demonstrated dose-dependent sedation with good rates of success at doses of 6.5 mg/kg along with good levels of patient and physician acceptance. Fospropofol has been associated with less pain at injection site than propofol. The most commonly reported side effects with fospropofol are paresthesia and pruritus. Fospropofol is a promising new sedation agent that appears to be well suited for MAC sedation, but further studies are needed to better understand its PK/PD properties as well its appropriate clinical role in outpatient procedures.

paresthesias were reported by 6 volunteers (46% during both IH and NIH tests. It is worth noting that paresthesias were only reported during NIH, by 2 participants (15.4%.The elimination T½ of CO during IH was comparable with the values reported during HOT, and lower than can be achieved with NOT or NIH. No serious adverse effects were reported during IH procedures. Further studies, especially direct comparisons with NOT and HOT, are necessary to evaluate the effectiveness of IH in the treatment of acute CO poisoning.

Neurologic complications of electrolyte disturbances and acid-base balance.

Espay, Alberto J

2014-01-01

Electrolyte and acid-base disturbances are common occurrences in daily clinical practice. Although these abnormalities can be readily ascertained from routine laboratory findings, only specific clinical correlates may attest as to their significance. Among a wide phenotypic spectrum, acute electrolyte and acid-base disturbances may affect the peripheral nervous system as arreflexic weakness (hypermagnesemia, hyperkalemia, and hypophosphatemia), the central nervous system as epileptic encephalopathies (hypomagnesemia, dysnatremias, and hypocalcemia), or both as a mixture of encephalopathy and weakness or paresthesias (hypocalcemia, alkalosis). Disabling complications may develop not only when these derangements are overlooked and left untreated (e.g., visual loss from intracranial hypertension in respiratory or metabolic acidosis; quadriplegia with respiratory insufficiency in hypermagnesemia) but also when they are inappropriately managed (e.g., central pontine myelinolisis when rapidly correcting hyponatremia; cardiac arrhythmias when aggressively correcting hypo- or hyperkalemia). Therefore prompt identification of the specific neurometabolic syndromes is critical to correct the causative electrolyte or acid-base disturbances and prevent permanent central or peripheral nervous system injury. This chapter reviews the pathophysiology, clinical investigations, clinical phenotypes, and current management strategies in disorders resulting from alterations in the plasma concentration of sodium, potassium, calcium, magnesium, and phosphorus as well as from acidemia and alkalemia. © 2014 Elsevier B.V.

Full Text Available Aim. Although inguinal hernia repair is the most frequently performed surgical procedure in the world, the best repair method has not gained acceptance yet. The ideal repair must be safe, simple, and easy to perform and require minimal dissection which provides enough exploration, maintain patient’s comfort in the early stage, and also be cost-effective, reducing operation costs, labor loss, hospital stay, and recurrence. Materials and Methods. There were eighty-five patients between the ages of 18 and 75, diagnosed with inguinal hernia in our clinic. Lichtenstein procedure for hernia repair was performed under spinal anesthesia in all patients. Forty-two patients had the standard procedure and, in 43 patients, the polypropylene mesh was used without fixation. All patients were examined and questioned on the 7th day of the operation in terms of pain, scrotal edema, and the presence of seroma and later on in the 6th postoperative month in terms of paresthesia, neuropraxia, and recurrence by a single physician. Results. Operative time and pain scores in the nonfixation group were significantly lower, without any increase in rates of recurrence. Conclusion. Based on these findings, in Lichtenstein hernia repair method, nonfixation technique can be used safely with better results.

Brown marbled grouper (Epinephelus fuscoguttatus) is an apex predator from coral reefs of the Indo-Pacific region. All five published case series of ciguatera after consumption of brown marbled grouper were reviewed to characterize the types, severity and chronicity of ciguatera symptoms associated with its consumption. Three of these case series were from large outbreaks affecting over 100-200 subjects who had eaten this reef fish served at banquets. Affected subjects generally developed a combination of gastrointestinal, neurological and, less commonly, cardiovascular symptoms. Gastrointestinal symptoms occurred early and generally subsided in 1-2 days. Some neurological symptoms (e.g., paresthesia of four limbs) could last for weeks or months. Sinus bradycardia and hypotension occurred early, but could be severe and prolonged, necessitating the timely use of intravenous fluids, atropine and dopamine. Other cardiovascular and neurological features included atrial ectopics, ventricular ectopics, dyspnea, chest tightness, PR interval >0.2 s, ST segment changes, polymyositis and coma. Concomitant alcohol consumption was associated with a much higher risk of developing bradycardia, hypotension and altered skin sensation. The public should realize that consumption of the high-risk fish (especially the ciguatoxin-rich parts and together with alcohol use) and repeated ciguatoxin exposures will result in more severe and chronic illness.

Unlike in children, brain stem gliomas in adult are rare and still poorly understood. In addition, most adult brain stem gliomas result predominantly in the pons and are less often found in the medulla oblongata. Here, we report a case of an adult glioma in the medulla oblongata and its molecular biological features. A 46-year-old male presented with gait disturbance, paresthesia, and dysphagia. Magnetic resonance imaging (MRI) showed a diffuse hyper-intensive lesion in the medulla oblongata on a T 2 -weighted image without gadolinium contrast enhancement. We performed an open biopsy and the lesion was pathologically diagnosed as a diffuse astrocytoma. Molecular biological analyses revealed the absence of histone H3.3 mutation (H3F3A K27M), and presence of methylation of O-6-methylguanine-DNA methyltransferase (MGMT) promoter and a mutation in isocitrate dehydrogenase 1 (IDH-1). The patient received local radiotherapy and temozolomide chemotherapy. The patient's symptoms were ameliorated, and MRI showed no tumor growth at 6 months after the initial treatment. Biopsy for brain stem lesions is generally thought to have risk of complications, but if performed minimally, it is useful to diagnose and determine treatment strategy. Obtaining patient characteristics and molecular biological features will provide insight towards therapeutic treatment for adult brain stem gliomas.

Delayed post-traumatic spinal cord infarction in an adult after minor head and neck trauma: a case report

Directory of Open Access Journals (Sweden)

Bartanusz Viktor

2012-09-01

Full Text Available Abstract Introduction Delayed post-traumatic spinal cord infarction is a devastating complication described in children. In adults, spinal cord ischemia after cardiovascular interventions, scoliosis correction, or profound hypotension has been reported in the literature. However, delayed spinal cord infarction after minor head trauma has not been described yet. Case presentation We report the case of a 45-year-old Hispanic man who had a minor head trauma. He was admitted to our hospital because of paresthesias in his hands and neck pain. A radiological workup showed cervical spinal canal stenosis and chronic cervical spondylotic myelopathy. Twelve hours after admission, our patient became unresponsive and, despite full resuscitation efforts, died. The autopsy revealed spinal cord necrosis involving the entire cervical spinal cord and upper thoracic region. Conclusions This case illustrates the extreme fragility of spinal cord hemodynamics in patients with chronic cervical spinal canal stenosis, in which any further perturbations, such as cervical hyperflexion related to a minor head injury, can have catastrophic consequences. Furthermore, the delayed onset of spinal cord infarction in this case shows that meticulous maintenance of blood pressure in the acute post-traumatic period is of paramount importance, even in patients with minimal post-traumatic symptoms.

Burning mouth syndrome – a common dental problem in perimenopausal women

Szponar, Elżbieta

2014-01-01

Burning mouth syndrome (BMS) is characterized by the presence of burning, paresthesia or pain of the oral mucosa in the absence of pathologic lesions revealed during the clinical examination. Moreover, the pain may be accompanied by oral dryness, hypersensitivity to some food compounds and taste disorders. Etiopathogenesis of this condition remains unclear. Potential local causative factors include among the others mechanical irritation, parafunctions and dysfunctions of the stomatognathic system, contact allergy to dental materials and electro-galvanic phenomena. Potential systemic causes include diabetes mellitus, B group vitamin deficiency (vitamins B1, B2, B6 and B12), folic acid and iron deficiency, hormonal imbalance, gastrointestinal diseases, psychiatric and neurological disorders and drug-induced side effects. The hypothesis concerning the role of hormonal changes in the development of BMS seems to be confirmed by a high incidence of this condition in perimenopausal women. Up to now, due to an unclear etiology of the disease, the treatment is very often ineffective and mainly symptomatic, which may exacerbate patient's anxiety and discomfort. In this paper we present the main etiologic factors of the burning mouth syndrome. We discuss the basic diagnostic and therapeutic methods and the influence of hormonal replacement therapy on the course of BMS based on the current medical reports. PMID:26327855

Primary hyperparathyroidism is an endocrine disorder recognized by hyperfunction of parathyroid gland, which can result in persistent bone absorption and brown tumor. Facial involvement of brown tumor is rare and usually involves the mandible. Giant cell tumor (GCT) is an expansile osteolytic bone tumor which is very similar in clinical, radiological and histological features to brown tumor. Herein, we present a 35-year-old woman with an 11-month history of gradually swelling of the right maxilla and buccal spaces began during pregnancy two years ago. No other clinical or laboratory problems were detected. Postpartum CT scan demonstrated a lytic expansile multi-septated mass lesion containing enhancing areas, which initially described as GCT of the right maxillary sinus following surgery. Four months later, gradual progressive swelling of the bed of tumor was recurred and revised pathological slices were compatible with GCT. Regarding patient recent paresthesia, repeated laboratory tests were performed. Finally, according to laboratory results (elevation of serum calcium and parathyroid hormone), ultrasonographic findings and radioisotope scan (Sestamibi), probable parathyroid mass and brown tumor of maxilla was diagnosed. Pathology confirmed hyperplasia of right inferior parathyroid gland. Our case was thought-provoking due to its interesting clinical presentation and unusual presentation of brown tumor in parathyroid hyperplasia

This cross-sectional study aimed to compare the effects of treatment with an atypical antipsychotic drug (olanzapine or risperidone) on quality of life (QoL) and to document adverse effects in 115 patients diagnosed with schizophrenia who attended the ambulatory service of Hospital Dr. João Machado, Natal, Rio Grande do Norte, Brazil. Socioeconomic, sociodemographic, and clinical variables were compared. The QoL Scale validated for Brazil (QLS-BR) was used to evaluate QoL, and adverse effects were assessed using the Udvalg for Kliniske Undersøgelser Side Effect Rating Scale. Data were analyzed using the χ(2) test and Student's t test, with a significance level of 5 %. Patients in both drug groups showed severe impairment in the occupational domain of the QLS-BR. Global QLS-BR scores indicated impairment among risperidone users and severe impairment among olanzapine users. The most significant side effects were associated with risperidone, including asthenia/lassitude/fatigue, somnolence/sedation, paresthesia, change in visual accommodation, increased salivation, diarrhea, orthostatic posture, palpitations/tachycardia, erythema, photosensitivity, weight loss, galactorrhea, decreased sexual desire, erectile/orgasmic dysfunction, vaginal dryness, headache, and physical dependence. QoL was impaired in patients using olanzapine and in those using risperidone. Risperidone use was associated with psychic, neurological, and autonomous adverse effects and other side effects.

Objective and Importance. Brainstem metastases (BSMs) are uncommon but serious complications of some cancers. They cause significant neurological deficit, and options for treatment are limited. Stereotactic radiosurgery (SRS) has been shown to be a safe and effective treatment for BSMs that prolongs survival and can preserve or in some cases improve neurological function. This case illustrates the use of repeated SRS, specifically Gamma Knife radiosurgery (GKRS) for management of a unique brainstem metastasis. Clinical Presentation. This patient presented 5 years after the removal of a lentigo maligna melanoma from her left cheek with left sided facial numbness and paresthesias with no reported facial weakness. Initial MRI revealed a mass on the left trigeminal nerve that appeared to be a trigeminal schwannoma. Intervention. After only limited response to the first GKRS treatment, a biopsy of the tumor revealed it to be metastatic melanoma, not schwannoma. Over the next two years, the patient would receive 3 more GKRS treatments. These procedures were effective in controlling growth in the treated areas, and the patient has maintained a good quality of life. Conclusion. GKRS has proven in this case to be effective in limiting the growth of this metastatic melanoma without acute adverse effects. PMID:24194991

The aim of this retrospective study was to describe the oral procedures used in osteo-odonto-keratoprosthesis (OOKP) surgery, and the demographics and oral findings of candidate patients in Singapore. The OOKP procedure utilizes an autologous tooth-bone complex to mount a poly-methylmethacrylate optical cylinder, as an artificial cornea, stabilized by an overlying autologous buccal mucosal graft. Consecutive patients referred over 3 years for dental evaluation prior to OOKP surgery were included. A total of 21 patients underwent oral clinical and radiographic evaluation. The aetiology of blindness included Stevens-Johnson's syndrome (11 cases), chemical burns (9 cases) and multiple failed corneal grafts (1 case). Evaluation revealed that 12 patients were suitable for OOKP surgery, 8 were at risk of complication or failure and 1 had no usable teeth. Fourteen patients have undergone unilateral OOKP Stage 1 surgery successfully. Complications included fracture of a tooth from its lingual bone necessitating the harvesting of a second tooth (1 case), oronasal perforation (1 case), exposure of adjacent roots (5 teeth), lower lip paresthesia (2 cases) and submucosal scar band formation in the buccal mucosal graft donor site (10 cases). Thirteen patients have completed Stage 2 surgery, with attainment of their best possible visual potential following OOKP surgery.

The purpose of this study was to compare overall patient satisfaction after orthognathic surgery with the following specific categories: appearance, functional ability, general health, sociability, and patient-clinician communication. A 16-question survey was developed and administered to include patients at either 6 or 12 months after orthognathic surgery between June 2013 and June 2014 at the University of Pennsylvania and Massachusetts General Hospital. The predictor variables included age, sex, type of procedure, medical comorbidities, intra- or postoperative complications, and presence of paresthesia. The outcome variable was patient satisfaction overall and in each category based on a Likert scale (0: not satisfied at all to 5: very satisfied).A total of 37 patients completed the survey and had a high overall rate of satisfaction (100% of responses were 4 or 5 on Likert scale). Overall satisfaction had the highest correlation with appearance (ρ=0.52, P=0.0009) followed by sociability (ρ=0.47, P=0.004), patient-clinician communication (ρ=0.38, P=0.02) functionality (ρ=0.19, P=0.26), and general health (ρ = -0.11, P = 0.51). Patients had high satisfaction scores for orthognathic surgery. Satisfaction with postoperative appearance had the strongest correlation with overall satisfaction.

The aim of this work is to demonstrate the accidents and complications rates on third molars surgeries performed by senior dentistry students. A retrospective study of 122 patient charts submitted to third molars surgeries was done. Patient age, gender, dental in arch position, and accidents/complications were considered with the charts presenting incomplete dates being excluded from the study. After all, 88 patients (210 surgeries) were included. The majority of the patients were female (70.4 %), with the average age of 24 years. Mandibular molars represented more than half of the surgical procedures (56.2 %), with teeth at vertical position the most found (60.3 %). The cases of accidents and complications totalized 10.4 % of all performed procedures, being hemorrhage (1.9 %), root fractures (1.9 %), and maxillary tuberosity fracture (1.9 %) the most found. Suture dehiscence (1.4 %), dry socket (1.4 %), oroantral communications (0.9 %), paresthesia (0.9 %), and infection (0.4 %) were also observed. Surgeons' inexperience was not considered a determinant factor to modify the rates of accidents and complications at third molars surgeries when compared to previous works developed by experienced surgeons. It is important to highlight the necessity of the students' knowledge of the most adequate treatments of each of the accidents and complications.

Full Text Available Brown marbled grouper (Epinephelus fuscoguttatus is an apex predator from coral reefs of the Indo-Pacific region. All five published case series of ciguatera after consumption of brown marbled grouper were reviewed to characterize the types, severity and chronicity of ciguatera symptoms associated with its consumption. Three of these case series were from large outbreaks affecting over 100–200 subjects who had eaten this reef fish served at banquets. Affected subjects generally developed a combination of gastrointestinal, neurological and, less commonly, cardiovascular symptoms. Gastrointestinal symptoms occurred early and generally subsided in 1–2 days. Some neurological symptoms (e.g., paresthesia of four limbs could last for weeks or months. Sinus bradycardia and hypotension occurred early, but could be severe and prolonged, necessitating the timely use of intravenous fluids, atropine and dopamine. Other cardiovascular and neurological features included atrial ectopics, ventricular ectopics, dyspnea, chest tightness, PR interval >0.2 s, ST segment changes, polymyositis and coma. Concomitant alcohol consumption was associated with a much higher risk of developing bradycardia, hypotension and altered skin sensation. The public should realize that consumption of the high-risk fish (especially the ciguatoxin-rich parts and together with alcohol use and repeated ciguatoxin exposures will result in more severe and chronic illness.

Full Text Available The case of a 54-year-old cardiac patient is reported, who was admitted to hospital with a complaint of sudden pain in the legs associated with edema, paresthesia, and coldness. Arterial embolism of the lower limbs was diagnosed and the patient was submitted to bilateral embolectomy. The patient evolved with a burning sensation, hypersensitivity in the right leg, swelling, and difficulty bending and stretching the sole of the foot and the knee. A physical examination detected edema and increased tension in the anterior, lateral, and posterior compartments. Treatment using intermittent massage of the leg during the evaluation of the patient was chosen in an attempt to stimulate lymphatic and venous drainage. After a few minutes of stimulation, there was significant improvement in the pain and edema. In 40 minutes, there was total reduction of the pain in the posterior and lateral compartments and improvement of over 50% in the anterior compartment. After this, the patient started to bend the knee without pain and bend the sole of the foot with slight pain. On the following day, the patient was walking around the hospital ward without difficulty. It seems that intermittent massage is a therapeutic option in selected cases of compartment syndrome.

Full Text Available BACKGROUND: Polyneuropathy, organomegaly, endocrinopathy, monoclonal syndrome (POEMS is a rare paraneoplastic syndrome associated with plasma cell dyscrasia. CASE REPORT: A 48-year-old man presented with a 1-year history of paresthesia and progressive weakness of extremities. Diagnosis of POEMS syndrome was made for him on the basis of clinical presentation, additional physical findings, typical sclerotic bone lesion, and bone marrow findings. In last admission, he explained episodes of dyspnea and chest pain that associated with frequent premature ventricular contraction in his electrocardiograph. Patient heart monitoring showed some episodes of complete heart block. Infra-His atrioventricular block in electro-physiologic study was detected. He had no history of ischemic heart disease. His cardiopulmonary findings on examination were normal. All results of cardiac biomarkers and serum electrolytes and repeated echocardiography were within normal range. Cong red staining of rectal fat pad biopsy was negative. After pacemaker insertion radiation of sclerotic bone, lesion started for him, but radiotherapy was ineffective, and he expired with respiratory failure. Complete heart block in POEMS syndrome has not been reported previously, and it is the first POEMS case with complete heart block. CONCLUSION: Complete heart block is a cardiac manifestation of POEMS syndrome.   Keywords: Complete Heart Block, POEM Syndrome, Multiple Meloma

Although hyperthyroidism arising from primary thyroid disease is rare in pregnancy, transient gestational hyperthyroidism is not uncommon. This condition can be associated with hyperemesis gravidarum (HG), and Wernicke's encephalopathy. We present the case of a woman with toxic nodular goiter complicating HG-associated Wernicke's encephalopathy. A 38-year-old Caucasian woman, who had received a diagnosis of hyperthyroidism and HG early in her pregnancy, had intrauterine fetal death at Week 16 of gestation. One day after undergoing therapeutic abortion, she was admitted to our clinic with persistent thyrotoxicosis, nausea, and vomiting. A toxic thyroid nodule was detected. She was given antithyroid medication, total parenteral nutrition. On Day 10 of hospitalization, she developed ataxia, aphasia, and somnolence. Cranial magnetic resonance imaging showed increased bilateral thalamic signalization. She was given a diagnosis of Wernicke's metabolic encephalopathy, for which she received thiamine and multivitamin preparations. She responded dramatically on the second day of thiamine therapy. Her consciousness improved rapidly and she began to speak. Her muscle tone was slightly weak and she had paresthesias in both legs. Absorption of thiamine may be particularly impaired in pregnant women with hyperemesis and hyperthyroid disease. Wernicke's encephalopathy should be considered in hyperthyroid women with HG who develop neurological abnormalities.

Full Text Available Primary hyperaldosteronism is one of the few causes of hypertension that can be cured by surgery. Primary hyperaldosteronism is caused by adrenocortical adenoma or hyperplasia. It is important to differentiate between adrenal adenoma and hyperplasia because the preferred treatments are different. In all patients with new-onest or worsening hypertension the primary hyperaldosteronism should be considered as an etiology. Patients with primary hyperaldosteronism classically have hypertension with spontaneous hypokalemia. The serum sodium concentration is usually normal in patients with primary aldosteronism who are not taking diuretics. Weakness, fatigue, paresthesia, tetany and even paralysis may develop. Renin and angiotensin II are suppressed in both forms of primary hyperaldosteronism due to feedback. Polyuria may develop secondary to vasopressin resistance from chronic hyperkaliuria. Hypertension or eclampsia during pregnancy is common in women with primary hyperaldosteronism. Case report: A 42-years-old woman presented with headache, severe hypertension, general weakness, easy fatigability, vertigo, palpitation, visual disorders and nocturia. She had a past history of eclampsia 10 years ago. In laboratory investigation there was hypokalemia, elevated serum aldosterone, low renin activity and hyperkaliuria. In abdominal CT-scan there was a hypodense mass measuring 2 cm in diameter in her left adrenal gland. The patient had primary hyperaldosteronism due to aldosteronoma.

Full Text Available Diabetic neuropathy is a severe complication of diabetes mellitus (DM that considerably worsens the patients quality of life and reduces life expectancy.The FIELD study for the first time demonstrated the ability of fenofibrate to prevent macro- and microvacular complications in patientswith DM2 regardless of glycated hemoglobin level and dyslipidemia at the early stage of the disease. Neuropathy being a manifestation of microangiopathy,it suggests the possibility to treat this disorder with fenofibrate.Aim. To study effects of fenofibrate in patients with type 2 diabetes mellitus complicated by diabetic neuropathy. Materials and methods. The present study included 73 patients with DM2 randomized into 2 groups to receive standard therapy (antihypertensiveand glucose control, statins or fenofibrate (Tricor 145 mg, Solvay Pharma in addition to the standard treatment. Results. Positive effect of fenofibrate on autonomous and peripheral neuropathy was apparent within 6 months after the onset of therapy when thesought parameters of AP, glycemia, and lipid spectrum were achieved. Fenofibrate improved cardiovascular function, reduced cardiac rhythm variability;QT length and dispersion, pain and paresthesia thereby enhancing quality of life and preventing cardiovascular catastrophes including death. Conclusion. It is concluded that supplementation of standard therapy of DM with fenofibrate is both safe and pathogenetically sound.

Churg-Strauss syndrome (CSS) is an anti-neutrophil cytoplasmic antibody (ANCA) associated vasculitis; it is extremely rare in childhood and defined according to the Chapel-Hill Consensus as an eosinophil-rich and granulomatous inflammation involving the respiratory tract and necrotizing vasculitis affecting small to medium-sized vessels. Children commonly have a history of asthma and sinusitis whilst clinical presentation typically involves pulmonary tract and less frequently skin, heart, gastrointestinal tract, and peripheral nerves. Cardiopulmonary disease is higher in children and prognosis is worse. It is associated with significant eosinophilia and raised serum IgE-levels. ANCA are only found in 25% of childhood cases. Here we report the case of a 10-year-old girl who presented to us with vomiting, abdominal pain, and weight loss, paresthesias of lower extremities and breathlessness as well as a history of asthma, sinusitis and allergic rhinitis. She was treated with corticosteroids, cyclophosphamide, intravenous immunoglobulin, mycophenolate mofetil (MMF), and rituximab. However, remission was only achieved after initiation of omalizumab therapy, a recombinant humanized anti-IgE antibody. To the best of our knowledge this is the first pediatric patient suffering from CSS successfully managed with adjuvant anti-IgE therapy resulting in the control of respiratory as well as gastrointestinal symptoms. © 2013 Wiley Periodicals, Inc.

Once the tumor becomes symptomatic, the various presentations may be related to the location and compression of adjacent structures. Meningioma is primarily treated through surgical intervention, and thus earlier diagnosis is likely to result in better prognosis. The symptoms of the meningioma may mimic other diseases, making precise diagnosis difficult, which will then delay treatment. We report a case of brain meningioma that showed initial signs and symptoms similar to cervical radiculopathy. The symptoms extended gradually, and the ultimate diagnosis of meningioma was confirmed based on brain-image studies. After brain-tumor excision, postoperation radiotherapy, and aggressive rehabilitation, the patient was able to perform better in daily activities.Keywords: hemiplegia, menigioma, paresthesia, radiculopathy, rehabilitation

OBJECT There is currently no consensus on the safety of sports participation for patients with Chiari I malformation (CM-I). The authors' goal was to define the risk of sports participation for children with the imaging finding of CM-I. METHODS A prospective survey was administered to 503 CM-I patients at 2 sites over a 46-month period. Data were gathered on imaging characteristics, treatment, sports participation, and any sport-related injuries. Additionally, 81 patients completed at least 1 subsequent survey following their initial entry into the registry and were included in a prospective group, with a mean prospective follow-up period of 11 months. RESULTS Of the 503 CM-I patients, 328 participated in sports for a cumulative duration of 4641 seasons; 205 of these patients participated in contact sports. There were no serious or catastrophic neurological injuries. One patient had temporary extremity paresthesias that resolved within hours, and this was not definitely considered to be related to the CM-I. In the prospective cohort, there were no permanent neurological injuries. CONCLUSIONS No permanent or catastrophic neurological injuries were observed in CM-I patients participating in athletic activities. The authors believe that the risk of such injuries is low and that, in most cases, sports participation by children with CM-I is safe.

Full Text Available OBJECTIVE: The aim of this study is to describe the risk factors associated with the presentation of brucellosis on the spine, and determine the strength of association between these factors. METHODS: The medical records of patients with brucellosis on the spine were analyzed and a spreadsheet was created to compile the following data: age, sex, place of origin and residence, risk factors (exposure at work, consumption of unpasteurized products and comorbidities, clinical presentation (lumbar pain, anorexia, headache, myalgia, fatigue, paresthesia, dysesthesia, muscle weakness, weight loss, fever, affected spine level, presence of abscesses, disease duration (acute, subacute, chronic, laboratory studies (erythrocyte sedimentation rate, C-reactive protein, serology, blood culture, Rose Bengal test, histopathological reports, imaging studies (x-rays, MRI, bone gammagraphy, established treatment (medical and/or surgical, therapeutic failure and sequelae. RESULTS: A total of 17 patients, 10 women (58.8% and seven men (41.2%, were reviewed from January 2007 to January 2011. The group had a mean age of 57.8 years with a standard deviation of +13.91 and age range between 16-74 years. CONCLUSIONS: There is no significant difference between the groups compared with respect to age and sex, however, improvement of the neurological deficit was observed in eight patients who underwent surgical procedure.

According to amputees, sensory feedback is amongst the most important features lacking from commercial prostheses. Although restoration of touch by means of implantable neural interfaces has been achieved, these approaches require surgical interventions, and their long-term usability still needs to be fully investigated. Here, we developed a non-invasive alternative which maintains some of the advantages of invasive approaches, such as a somatotopic sensory restitution scheme. We used transcutaneous electrical nerve stimulation (TENS) to induce referred sensations to the phantom hand of amputees. These sensations were characterized in four amputees over two weeks. Although the induced sensation was often paresthesia, the location corresponded to parts of the innervation regions of the median and ulnar nerves, and electroencephalographic (EEG) recordings confirmed the presence of appropriate responses in relevant cortical areas. Using these sensations as feedback during bidirectional prosthesis control, the patients were able to perform several functional tasks that would not be possible otherwise, such as applying one of three levels of force on an external sensor. Performance during these tasks was high, suggesting that this approach could be a viable alternative to the more invasive solutions, offering a trade-off between the quality of the sensation, and the invasiveness of the intervention.

Spontaneous Cervical Intradural Disc Herniation Associated with Ossification of Posterior Longitudinal Ligament

Full Text Available Intradural herniation of a cervical disc is rare; less than 35 cases have been reported to date. A 52-year-old man with preexisting ossification of posterior longitudinal ligament developed severe neck pain with Lt hemiparesis while asleep. Neurological exam was consistent with Brown-Séquard syndrome. Magnetic resonance images showed a C5-6 herniated disc that was adjacent to the ossified ligament and indenting the cord. The mass was surrounded by cerebrospinal fluid signal intensity margin, and caudally the ventral dura line appears divided into two, consistent with the “Y-sign” described by Sasaji et al. Cord edema were noted. Because of preexisting canal stenosis and spinal cord at risk, a laminoplasty was performed, followed by an anterior C6 corpectomy. Spot-weld type adhesions of the posterior longitudinal ligament to the dura was noted, along with a longitudinal tear in the dura. An intradural extra-arachnoid fragment of herniated disc was removed. Clinical exam at 6 months after surgery revealed normal muscle strength but persistent mild paresthesias. It is difficult to make a definite diagnosis of intradural herniation preoperatively; however, the clinical findings and radiographic signs mentioned above are suggestive and should alert the surgeon to look for an intradural fragment.

Full Text Available Side effects of antimalarial drug can overlap with malaria symptoms. We evaluated 50 patients with vivax malaria in Mâncio Lima, Acre, treated with chloroquine and primaquine. Patients were evaluated for the presence of 21 symptoms before and after treatment and for reported side effects of these drugs after treatment was started. The most frequent symptoms before medication were headache, fever, chills, sweating, arthralgia, back pain, and weakness, which were present in between 40% and 76% of respondents. The treatment reduced the occurrence of these symptoms and reduced the lack of appetite, but gastrointestinal symptoms and choluria increased in frequency. There were no reports of pale stools before medication, but 12% reported the occurrence of this symptom after treatment started. Other symptoms such as blurred vision (54%, pruritus (22%, paresthesia (6%, insomnia (46%, and “stings” into the skin (22% were reported after chloroquine was taken. The antimalarial drugs used to treat P. vivax malaria reduce much of the systemic and algic symptoms but cause mainly gastrointestinal side effects that may lead to lack of adherence to drug treatment. It is important to guide the patient for the appearance and the transience of such side effects in order to avoid abandoning treatment.

Topiramate induced peripheral neuropathy: A case report and review of literature.

Drug-induced peripheral neuropathy had been rarely reported as an adverse effect of some antiepileptic drugs (AEDs) at high cumulative doses or even within the therapeutic drug doses or levels. We describe clinical and diagnostic features of a patient with peripheral neuropathy as an adverse effect of chronic topiramate (TPM) therapy. A 37-year-old woman was presented for the control of active epilepsy (2010). She was resistant to some AEDs as mono- or combined therapies (carbamazepine, sodium valproate, levetiracetam, oxcarbazepine and lamotrigine). She has the diagnosis of frontal lobe epilepsy with secondary generalization and has a brother, sister and son with active epilepsies. She became seizure free on TPM (2013-2017) but is complaining of persistent distal lower extremities paresthesia in a stocking distribution. Neurological examination revealed presence of diminished Achilles tendon reflexes, stocking hypesthesia and delayed distal latencies, reduced conduction velocities and amplitudes of action potentials of posterior tibial and sural nerves, indicating demyelinating and axonal peripheral neuropathy of the lower extremities. After exclusion of the possible causes of peripheral neuropathy, chronic TPM therapy is suggested as the most probable cause of patient's neuropathy. This is the first case report of topiramate induced peripheral neuropathy in the literature.

2018-03-01

Supernumerary or accessory heads of the biceps brachii are persistent muscular structures which can vary in number and location in the arm. Variations in other arm muscles, such as the coracobrachialis, can accompany supernumerary biceps brachii musculature in the upper limb. In this case report, we describe two rare muscular variants in a single adult male: a four-headed biceps brachii and the muscular elevator of the latissimus dorsi tendon. Additionally, accessory muscles of the brachialis and flexor digiti minimi brevis were identified in the upper limb. To our knowledge, the muscular variants identified here are considered rare, and their co-occurrence in a single upper limb has not been described previously. Also, a four-headed biceps brachii consisting of both the infero-medial and infero-lateral humeral heads has not been described previously to our knowledge. We postulate that the simultaneous appearance of several muscular variations may indicate a signaling disruption in embryogenesis during muscle patterning of the ventral limb bud. Knowledge of variant musculature in the arm is important for surgeons and clinicians as these muscles and their aberrant innervation patterns can complicate surgical procedures and may compress arteries and nerves producing upper limb pain and paresthesia. The clinical, functional and embryological implications of the upper limb variants are discussed.

Pneumomediastinum, Subcutaneous Emphysema, and Tracheal Tear in the Early Postoperative Period of Spinal Surgery in a Paraplegic Achondroplastic Dwarf

Directory of Open Access Journals (Sweden)

Sinan Kahraman

2013-01-01

Full Text Available Achondroplasia was first described in 1878 and is the most common form of human skeletal dysplasia. Spinal manifestations include thoracolumbar kyphosis, foramen magnum, and spinal stenosis. Progressive kyphosis can result in spinal cord compression and paraplegia due to the reduced size of spinal canal. The deficits are typically progressive, presenting as an insidious onset of paresthesia, followed by the inability to walk and then by urinary incontinence. Paraplegia can be the result of direct pressure on the cord by bone or the injury to the anterior spinal vessels by a protruding bone. Surgical treatment consists of posterior instrumentation, fusion with total wide laminectomy at stenosis levels, and anterior interbody support. Pedicle screws are preferred for spinal instrumentation because wires and hooks may induce spinal cord injury due to the narrow spinal canal. Pedicle lengths are significantly shorter, and 20–25 mm long screws are appropriate for lower thoracic and lumbar pedicles in adult achondroplastic There is no information about the appropriate length of screws for the upper thoracic pedicles. Tracheal injury due to inappropriate pedicle screw length is a rare complication. We report an extremely rare case of tracheal tear due to posterior instrumentation and its management in the early postoperative period.

Johnson-Arbor, Kelly

2012-01-01

Decompression sickness (DCS) of an inside attendant (IA) is rarely encountered in hyperbarics. This report describes an IA who developed Type II DCS after a routine hyperbaric exposure. A 50-year-old male complained of lower extremity weakness and paresthesias after serving as an IA during a hyperbaric treatment to 40 fsw (122.52 kPa). Within 10 minutes after the conclusion of the treatment, the IA experienced irritability and confusion, and was unable to walk. Physical examination revealed decreased sensation below the T7 level, and decreased strength in the lower extremities. Type II DCS was diagnosed, and the IA was recompressed to 60 fsw (183.78 kPa) on a U.S. Navy Treatment Table 6, which resulted in improvement of his symptoms. Transthoracic echocardiography with bubble study performed 16 months after the event demonstrated a large patent foramen ovale (PFO). Increased age, decreased physical fitness and the undiagnosed PFO may have predisposed this attendant to developing DCS. Although rare, DCS may occur in IAs. Routine monitoring and reporting of the long-term health of hyperbaric IAs should be considered by hyperbaric facilities and medical directors in order to further understand the characteristics of DCS and other hyperbaric-related conditions in these workers.

The use of electrocautery for tissue dissection is becoming increasingly popular, despite the associated risk of poor wound healing and excessive scarring. We conducted this study to compare the wound complications and early and late clinical results resulting from electrocautery versus the scalpel to create a cutaneous flap during thyroidectomy. The subjects of this study were 100 patients, randomized prospectively to either a scalpel group (group S, n = 50) or an electrocautery group (group E, n = 50). Thickness of tissue damage, postoperative thickness of the flap, discomfort in the neck 7 days after surgery, and hypoesthesia and paresthesia in the neck 3 months after surgery were significantly higher in group E than in group S. There were no significant differences in overall postoperative wound complications, postoperative pain, satisfaction with the cosmetic result, or overall outcome of the operation between the groups. Although the incidence of seroma was higher in group E (20%) than in group S (8%), the difference was not significant. Although electrocautery was associated with increased histological tissue damage, postoperative flap edema, discomfort, and other complications in the early stage, the clinical and cosmetic results of flaps made using electrocautery or a scalpel were similar and satisfactory 6 months after surgery.

Schwannoma of the Median Nerve at the Wrist and Palmar Regions of the Hand: A Rare Case Report

Full Text Available Schwannomas are also known as neurolemmas that are usually originated from Schwann cells located in the peripheric nerve sheaths. They are the most common tumours of the hand (0.8–2%. They usually present solitary swelling along the course of the nerve however multiple lesions may be present in cases of NF type 1, familial neurofibromatosis, and sporadic schwannomatosis. Schwannomas are generally represented as an asymptomatic mass; however pain, numbness and fatigue may take place with the increasing size of the tumour. EMG (electromyelography, MRI (magnetic resonance imagination, and USG (ultrasound are helpful in the diagnosis. Surgical removal is usually curative. In this paper, we present a 24-year-old male referred to our clinic for a lump located at the volar side of the left wrist and a lump located in his left palm and numbness at his 3rd and 4th fingers. Total excision was performed for both lesions. Histopathological examination of the masses revealed typical features of schwannoma. At the 6th-month followup the patient was symptom-free except for slight paresthesia of the 3rd and the 4th fingers. For our knowledge, this is the second case in the literature presenting wrist and palm involvement of the median nerve schwannoma.

Paresthesias are the first symptom that people report following toxic doses of methylmercury. The authors conducted a psychophysical study of tactile sensation to evaluate the somatosensory abilities of subjects living in a methylmercury-polluted area around Minamata City, Japan. The authors examined control subjects and methylmercury-exposed subjects with and without numbness. A history of methylmercury exposure was taken and a neurological examination performed. Aluminum-oxide abrasive papers were used as stimuli in a psychophysical sensory examination of fine-surface-texture discrimination. Difference thresholds from 3 μm were calculated by the two-alternative, forced-choice technique. Difference thresholds in control subjects were also calculated for comparison. The difference threshold was 6.3 μm in exposed subjects with sensory symptoms, 4.9 μm in exposed subjects without sensory symptoms, and 2.7 μm in control subjects. Acuity of fine-surface-texture discrimination was disturbed not only in subjects with clinical complaints of hand numbness, but also in subjects without hand numbness who lived in the district where methylmercury exposure occurred. Sensory testing using a psychophysical test of fine-surface-texture discrimination in this population suggests that the number of individuals affected by methylmercury exposure in the polluted area was greater than previously reported

Full Text Available Cutaneous nerve injury is the most common complication following foot and ankle surgery. However, clinical studies including long-term follow-up data after cutaneous nerve injury of the foot and ankle are lacking. In the current retrospective study, we analyzed the clinical data of 279 patients who underwent foot and ankle surgery. Subjects who suffered from apparent paresthesia in the cutaneous sensory nerve area after surgery were included in the study. Patients received oral vitamin B 12 and methylcobalamin. We examined final follow-up data of 17 patients, including seven with sural nerve injury, five with superficial peroneal nerve injury, and five with plantar medial cutaneous nerve injury. We assessed nerve sensory function using the Medical Research Council Scale. Follow-up immediately, at 6 weeks, 3, 6 and 9 months, and 1 year after surgery demonstrated that sensory function was gradually restored in most patients within 6 months. However, recovery was slow at 9 months. There was no significant difference in sensory function between 9 months and 1 year after surgery. Painful neuromas occurred in four patients at 9 months to 1 year. The results demonstrated that the recovery of sensory function in patients with various cutaneous nerve injuries after foot and ankle surgery required at least 6 months

Full Text Available Introduction: Malignent Fibrous Histiocytoma (MFH is the most frequent soft tissue sarcoma of adulthood. The most common sites affected by MFH are limbs, orbit, retroperitoneum, pelvis and knee. Oral cavity and mandible involvements are very rare. Case Report: A 35-year-old male was visited in the oral medicine department of Hamadan dental school with the chief complaint of pain and teeth mobility. The patient also had a history of paresthesia in lower lip for two monthes. In intraoral examination, there was a crater like, deep and disseminated ulcer in lower buccal and ligual gingiva of right mandibular teeth and exophitic lesion with smooth surface, and color similar to normal mucosa with 2×2×3 cm in diameter in buccal and lingual part of right lateral and central teeth extended to left second premolar was observed. Gingival resorption was observed in all adjascent teeth. There was radiolucency with irregular border in all part of lesion. MFH was confirmed by histopathological report.Conclusion: The most common complaint of patients with malignant fibrous histiocytoma is the growing mass that could be ulcerative or painful. Early diagnosis and referral is very important in prognosis and survival of the patients.

Full Text Available Introduction: A lipoma is a benign tumor of the adipose tissue and the most common tumor of the subcutaneous tissue which is most commonly found on the trunk. It appears as a round or oval subcutaneous mass of soft consistency, which is not attached to the skin or to the deeper tissues. Its growth can cause compressive symptoms, the most common being pain and paresthesia. Case report: Considering the fact that lipomas very rarely occur in the hand and foot, in this paper we present a case of a large lipoma in the hand of a 70-year-old female patient, with a subcutaneous tumor, in the area of the ulnar side of the left palm, and the pain and tingling in the fourth and fifth finger. Longitudinal incision on the medial side of the palm and transversal incision up to the proximal palmar crease were performed under general endotracheal anesthesia. The extirpated tumor was, due to its dimensions (5.6 x 3.4 x 2.5 cm, categorized as a giant hand lipoma. A histopathological analysis confirmed the diagnosis of lipoma. Conclusion: A hand lipoma requires surgical treatment exclusively, involving a qualified hand surgeon, which is important because of the high functional and aesthetic importance of the hand.

Full Text Available The linkage between brain response to acupuncture and subsequent analgesia remains poorly understood. Our aim was to evaluate this linkage in chronic pain patients with carpal tunnel syndrome (CTS. Brain response to electroacupuncture (EA was evaluated with functional MRI. Subjects were randomized to 3 groups: (1 EA applied at local acupoints on the affected wrist (PC-7 to TW-5, (2 EA at distal acupoints (contralateral ankle, SP-6 to LV-4, and (3 sham EA at nonacupoint locations on the affected wrist. Symptom ratings were evaluated prior to and following the scan. Subjects in the local and distal groups reported reduced pain. Verum EA produced greater reduction of paresthesia compared to sham. Compared to sham EA, local EA produced greater activation in insula and S2 and greater deactivation in ipsilateral S1, while distal EA produced greater activation in S2 and deactivation in posterior cingulate cortex. Brain response to distal EA in prefrontal cortex (PFC and brain response to verum EA in S1, SMA, and PFC were correlated with pain reduction following stimulation. Thus, while greater activation to verum acupuncture in these regions may predict subsequent analgesia, PFC activation may specifically mediate reduced pain when stimulating distal acupoints.

2016-01-01

In the era of video-assisted thoracoscopic surgery (VATS), uniportal and single incision thoracoscopic surgeries are gaining popularity. The spectrum of uniportal VATS indications is now almost equal to that of conventional VATS. For example, successful uniportal sleeve lobectomy, rib segmental resection, and management of intraoperative bleeding have all been reported. According to published data in the English-language literature, more than 9,545 uniportal VATS have been performed to date, including 1,293 lobectomies, 1,024 procedures for pneumothorax, and 6,845 sympathectomies. Of the 192 articles discussing this topic, 35 were conducted in Spain, and there were an increasing number of publications from China, Korea, and other Asian countries. There were 41 technical and review articles, all of which provided an excellent foundation of surgical concept and skill learning. The benefits of uniportal VATS include better surgical geometry and cosmetics. Regarding postoperative outcomes, thirteen out of the 15 articles reviewed showed that uniportal VATS has similar or superior outcomes to conventional VATS. Most studies demonstrated that uniportal VATS produced less postoperative pain and paresthesia. In conclusion, uniportal VATS can produce excellent operative outcome, which is becoming a mature surgical approach in thoracic disease, supported by fast-accumulating and abundant experience.

The aim of this hospital-based survey was to determine baseline stroke knowledge in Croatian population attending the outpatient services at the Department of Neurology. A multiple choice questionnaire was designed, divided into three sections: (i) demographic data, (ii) knowledge of stroke risk factors and stroke signs and (iii) actions the patients would undertake if confronted with risk of stroke and information resources regarding health. The analysis included 720 respondents (54.9% women). The respondents most frequently indicated stroke symptoms as following: speech disorder 82%, paresthesiae on one side of the body 71%, weakness of arm or leg 55%, unsteady gait 55%, malaise 53%, monocular loss of vision 44%. The risk factors most frequently identified were hypertension 64%, stress 61%, smoking 59%, elevated lipids 53%, obesity 52%, coagulation disorder 47%, alcoholism 45%, low-physical activity 42%, elderly age 39%, cardiac diseases 38%, weather changes 34%, drugs 33% and diabetes 32%. If confronted with stroke signs 37% of respondents would consult the general practitioner and 31% would call 911 or go to a neurologist. Amongst patients with a risk factor, only diabetics were aware that their risk factor might cause stroke (P risk factors for stroke. The results of our study will help to create and plan programmes for improvement of public health in Croatia.

Full Text Available ABSTRACT INTRODUCTION: the fishing activity throughout the Upper Paraguay River Basin has huge financial and biological importance. This retrospective study investigated the occurrence of injuries caused by fish of the Pseudoplatystoma genus (spotted catfish or pintado and striped catfish or cachara in professional fishermen of the Pantanal of Mato Grosso do Sul State. METHODS: we collected information through a questionnaire, showing that fishing is carried out by workers with low level of education, mainly adults or seniors with low financial gains. RESULTS: in Miranda town, 126 of 315 fishermen were interviewed and 38 individuals reported injuries (30.16%. In Corumbá town, 355 of 627 fishermen were interviewed, and 111 (56,61% reported injuries. The lacerated lesions were the most common, associate with edema, erythema, radiating pain to the root of the limb, paresthesias and local necrosis. More rarely, they reported the occurrence of fever, cardiac arrhythmias and cold sweating. These manifestations may be associated with late secondary infections or envenomations caused by the toxins in the stingers of the fish. Many questionable and inappropriate treatments are used, sometimes aggravating the injuries. CONCLUSIONS: the freshwater professional fishermen need guidance on first aid measures and prevention of accidents caused by these venomous fish.

for months and years, there is a possibility that every medic can encounter its unusual symptoms, requiring specific treatment. The following toxins cause the poisoning: ciguatoxin, meitotoxin, ostreotoxin, domoic acid and some other unspecified toxins. They are lipid soluble, thermo stable and cannot be decomposed by culinary processing. These toxins have neurotoxic, cardiotoxic, hemolytic properties and cause diarrheic syndrome. Clinical presentation is characterized by average latent period of 12 hours after the consummation, vomiting and diarrhea next 24 hours and neurological symptoms that appear at the beginning of the poisoning with paresthesias along the body, changing feeling of hot and cold, strong myalgia. Disturbances in cardiac rhythm and conduction, strong dehydration or shock are possible in severe cases. Light cases pass over in several days, but, more often the poisoning has a chronic course – from 3-4 months to 1 year, with prevalence of neurologic symptoms: myalgia, paresthesias, skin itching with scratches, depression. The management is not specific and includes stomach lavage with activated charcoal, fluids replacement during the first 24 hours, corticosteroids, antiallergics, high doses of vitamins from group B (Vit. B1, Vit. B6, Vit. B12, mannitol IV, nootropic medicaments, antidepressants and other symptomatic medicaments. The prophylaxis is done by examining every fish with specific test for detecting ciguateratoxin.

The total sample was divided into the anxiety and depressive disorder group (GTDA (n = 26 and the control group (CG (n = 22. RESULTS: B-K total scores were greater in the GTDA comparing with the CG (22.6 vs. 13.7. Paresthesia and melancholia were significantly more severe in the GTDA. GTDA patients also complained of a greater number of symptoms (6.8 vs. 4.8 than the GC. Paresthesia, weakness and melancholia were significantly more present in the GTDA. CONCLUSION: Although the small sample limitation we could observe a great bias of depressive and anxiety disorders over menopause outpatients. For that reason, the symptomatic profile of each patient must always be observed by the gynecologist, avoiding exclusive observation of B-K total score to decide about the treatment.

Full Text Available Burning mouth syndrome (BMS is characterized by the presence of burning, paresthesia or pain of the oral mucosa in the absence of pathologic lesions revealed during the clinical examination [1-3]. Moreover, the pain may be accompanied by oral dryness, hypersensitivity to some food compounds and taste disorders [4-6]. Etiopathogenesis of this condition remains unclear. Potential local causative factors include among the others mechanical irritation, parafunctions and dysfunctions of the stomatognathic system, contact allergy to dental materials and electro-galvanic phenomena. Potential systemic causes include diabetes mellitus, B group vitamin deficiency (vitamins B1, B2, B6 and B12, folic acid and iron deficiency, hormonal imbalance, gastrointestinal diseases, psychiatric and neurological disorders and drug-induced side effects. The hypothesis concerning the role of hormonal changes in the development of BMS seems to be confirmed by a high incidence of this condition in perimenopausal women [2, 7, 8]. Up to now, due to an unclear etiology of the disease, the treatment is very often ineffective and mainly symptomatic, which may exacerbate patient’s anxiety and discomfort. In this paper we present the main etiologic factors of the burning mouth syndrome. We discuss the basic diagnostic and therapeutic methods and the influence of hormonal replacement therapy on the course of BMS based on the current medical reports.

Burning mouth syndrome (BMS) is a chronic oral pain syndrome that primarily affects peri- and postmenopausal women. It is characterized by oral mucosal burning and may be associated with dysgeusia, paresthesia, dysesthesia, and xerostomia. The etiology of the disease process is unknown, but is thought to be neuropathic in origin. The goal of this systematic review was to assess the efficacy of the various treatments for BMS. Literature searches were conducted through PubMed, Web of Science, and Cochrane Library databases, which identified 22 randomized controlled trials. Eight studies examined alpha-lipoic acid (ALA), three clonazepam, three psychotherapy, and two capsaicin, which all showed modest evidence of potentially decreasing pain/burning. Gabapentin was seen in one study to work alone and synergistically with ALA. Other treatments included vitamins, benzydamine hydrochloride, bupivacaine, Catuama, olive oil, trazodone, urea, and Hypericum perforatum. Of these other treatments, Catuama and bupivacaine were the only ones with significant positive results in symptom improvement. ALA, topical clonazepam, gabapentin, and psychotherapy may provide modest relief of pain in BMS. Gabapentin may also boost the effect of ALA. Capsaicin is limited by its side effects. Catuama showed potential for benefit. Future studies with standardized methodology and outcomes containing more patients are needed. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Touch perception on the fingers and hand is essential for fine motor control, contributes to our sense of self, allows for effective communication, and aids in our fundamental perception of the world. Despite increasingly sophisticated mechatronics, prosthetic devices still do not directly convey sensation back to their wearers. We show that implanted peripheral nerve interfaces in two human subjects with upper limb amputation provided stable, natural touch sensation in their hands for more than 1 year. Electrical stimulation using implanted peripheral nerve cuff electrodes that did not penetrate the nerve produced touch perceptions at many locations on the phantom hand with repeatable, stable responses in the two subjects for 16 and 24 months. Patterned stimulation intensity produced a sensation that the subjects described as natural and without "tingling," or paresthesia. Different patterns produced different types of sensory perception at the same location on the phantom hand. The two subjects reported tactile perceptions they described as natural tapping, constant pressure, light moving touch, and vibration. Changing average stimulation intensity controlled the size of the percept area; changing stimulation frequency controlled sensation strength. Artificial touch sensation improved the subjects' ability to control grasping strength of the prosthesis and enabled them to better manipulate delicate objects. Thus, electrical stimulation through peripheral nerve electrodes produced long-term sensory restoration after limb loss. Copyright © 2014, American Association for the Advancement of Science.

The infraorbital nerve (ION) is a terminal branch of the maxillary nerve (V2) providing sensory innervation to the malar skin. It is sometimes necessary to sacrifice the ION and its branches to obtain adequate maxillary sinus exposure for radical resection of sinonasal tumors. Consequently, patients suffer temporary or permanent paresthesia, hypoestesthia, and neuralgia of the face. We describe an innovative technique used for preservation of the ION while removing the anterior, superior, and lateral walls of the maxillary sinus through a medial endoscopic transnasal maxillectomy. All patients who underwent transnasal endoscopic maxillectomy with ION transposition in our institute were retrospectively reviewed. Two patients were identified who had been treated for sinonasal cancers using this approach. No major complications were observed. Transient loss of ION function was observed with complete recovery of skin sensory perception within 6 months of surgery. One patient referred to a mild permanent anesthesia of the upper incisors. No diplopia or enophthalmos were encountered in any of the patients. The ION transposition is useful for selected cases of benign and malignant sinonasal tumors that do not infiltrate the ION itself but involve the surrounding portion of the maxillary sinus. Anatomic preservation of the ION seems to be beneficial to the postoperative quality of life of such patients. © 2016 ARS-AAOA, LLC.

This study aimed to evaluate the effect of health education combining diet and exercise supervision on menopausal symptoms and diet/exercise habits. The randomized controlled study enrolled 60 patients with perimenopausal syndrome (Kupperman Menopause Index (KMI) score ≥15). The participants were randomized into either an intervention group (n = 30) or a control group (n = 30). Women were interviewed with questionnaires about perimenopausal symptoms, diet pattern and exercise habit. Their height and weight were measured. Women in the intervention group received health education, diet supervision and exercise supervision twice a week while those in the control group continued as normal. The total KMI score, scores of individual symptoms, diet pattern and exercise habit were measured after intervention. The total KMI score, the individual KMI scores for paresthesia, irritability, depression/suspicious, fatigue, arthralgia/myalgia, and palpitations of the intervention group were significantly lower compared with the control group after intervention. The intake of cereal, meat, fats and oils of the intervention group were significantly lower at week 12 compared with baseline. The percentage of women with a regular exercise habit was significantly higher in the intervention group than in the control group after intervention. Twelve weeks intervention of health education combining diet and exercise supervision could improve perimenopausal symptoms and help the patients establish good living habits.

Full Text Available Introduction: Topiramate was serendipitously synthesized in 1979 during research aimed at developing a fructose-1,6-diphosphatase inhibitor that might be used in the treatment of diabetes mellitus. Some investigators have suggested it might be used in the treatment of binge eating disorder (BED. The aim of this review was to evaluate current knowledge and opinions on this topic. Materials and methods: We conducted a search of five electronic databases (PubMed, Embase, Nice, Cochrane, Cinahl using the search strategy ‘‘topiramate’’ AND ‘‘binge’’, ‘‘binge eating disorder.’’ No time limits were applied, and only reports of randomized controlled trials were included in our analysis. Results: In clinical studies, topiramate use has been associated with significant weight loss mediated by reductions in the frequency of bingeing episodes. The most common side effects of the drug are paresthesias, but nephrolithiasis, oligohydrosis, and dizziness have also been described. Conclusions: Available data are limited, but the literature we reviewed suggests that topiramate can be useful in the medical treatment of BED, reducing both body weight and binge episodes. Side effects are not negligible. Before topiramate can be regarded as a good tool for the treatment of BED, further data must be obtained from longer, methodologically correct studies of larger populations.

A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used. (author)

2002-01-01

Restless legs syndrome (RLS) is defined by an irresistible need to move associated with leg paresthesia. Two additional features are essential for diagnosis: (1) worsening of symptoms at rest with temporary relief by activity, and (2) worsening of symptoms during the evening and/or during the night. The suggested immobilization test (SIT) has been developed to evaluate the presence of these criteria. This test quantifies leg movements and leg discomfort during a 1-hour period of immobility prior to bedtime. We used the SIT to evaluate the effects of immobility on leg discomfort and leg movements experienced by 19 patients with RLS and 19 control subjects. Results show that immobility significantly worsens both leg discomfort and periodic leg movements (PLM) in patients with RLS but not in controls. Patients with RLS showed a higher leg discomfort score (32.6 +/- 15.1 mm vs. 5.7 +/- 7.9 mm; P < 0.00001), a greater maximum leg discomfort value (63.4 +/- 27.4 mm vs. 13.7 +/- 23.0 mm; P < 0.00001) and a greater PLM index (88.4 +/- 62.6 vs. 10.4 +/- 20.6; P < 0.00004) than control subjects. These results further validate the use of the SIT as a diagnostic and research tool for RLS and confirm the contention of the International RLS study group that RLS symptoms worsen at rest.

There are a variety of techniques for targeting placement of an infraclavicular blockade; these include eliciting paresthesias, nerve stimulation, and 2-dimensional (2D ultrasound (US guidance. Current 2D US allows direct visualization of a “flat” image of the advancing needle and neurovascular structures but without the ability to extensively analyze multidimensional data and allow for real-time manipulation. Three-dimensional (3D ultrasonography has gained popularity and usefulness in many clinical specialties such as obstetrics and cardiology. We describe some of the potential clinical applications of 3D US in regional anesthesia. Methods. This case represents an infraclavicular catheter placement facilitated by 3D US, which demonstrates 360-degree spatial relationships of the entire anatomic region. Results. The block needle, peripheral nerve catheter, and local anesthetic diffusion were observed in multiple planes of view without manipulation of the US probe. Conclusion. Advantages of 3D US may include the ability to confirm correct needle and catheter placement prior to the injection of local anesthetic. The spread of local anesthetic along the length of the nerve can be easily observed while manipulating the 3D images in real-time by simply rotating the trackball on the US machine to provide additional information that cannot be identified with 2D US alone.

Whiplash injury (WI) is commonly evaluated in medico-legal practice. With the aim of knowing the determining factors of WI's medico-legal prognosis, a prospective and observational study was carried out. One hundred and twenty consecutive patients who were clinically observed and evaluated in the Medico-Legal Clinic of Barcelona were studied. Socio-demographic, clinical, radiographic and evolutive factors were analyzed. We included 120 patients with a mean age of 35.6 (14) years (range, 4-74), with a homogeneous male/female distribution. An earlier cervical pathology was detected in 10% of patients; none of them had previous psychiatric pathology. 95% corresponded to road-traffic accident cases and there were 5 aggression cases. Over 50% of cases involved a rear-end collision. All patients had neck pain, almost 25% had headache and 13% had paresthesia. According to the Whiplash Association Disorders clinical classification, distribution in grades (G) was: G I 51%, G II 32% and G III 17%. Patients reported recovery within a mean time of 71.6 (46) days (range, 4-244), with 51,2 (45) no working days (range, 0-180 days). The 52% of the patients rest with complains. According to the recovery time, the following medico-legal prognostic factors were identified: age (p legal prognostic factors were age, being females, severity of initial clinical symptoms, previous cervical pathology and abnormal cervical MRI/CT.

Hereditary neuropathy with liability to pressure palsy (HNPP) is an autosomal dominant neuropathy. It is characterized by recurrent sensory and motor nerve palsies, usually precipitated by minor trauma or compression. Even though rare in childhood, this disorder is probably underdiagnosed given its wide spectrum of clinical symptoms. We review three separate cases of HNPP diagnosed in children with various phenotypes: fluctuating and distal paresthesias disrupting learning at school, cramps related to intensive piano practice, and discrete muscle weakness with no functional complaint. Family history should be carefully reviewed to identify potential undiagnosed HNPP cases, as in our three reports. Electrophysiological study is essential for the diagnosis, with a double advantage: to confirm the presence of focal abnormalities in clinically symptomatic areas and to guide molecular biology by revealing an underlying demyelinating polyneuropathy. The diagnosis of HNPP is confirmed by genetic testing, which in 90% of cases shows a 1.5-Mb deletion of chromosome 17p11.2 including the PMP22 gene. Patients are expected to make a full recovery after each relapse. However, it is very important for both the patient and his or her family to establish a diagnosis in order to prevent recurrent palsy brought on by situations involving prolonged immobilizations leading to nerve compression.

Context Scrub typhus is an acute febrile disease caused by Orientia tsutsugamushi. The disease can usually involve the lungs, heart, liver, spleen and brain through hematogenous dissemination. However, very rarely, acute transverse myelitis in the spinal cord develops from scrub typhus. We present a case of acute transverse myelitis following scrub typhus with a review of the literature. Findings A 66-year-old male visited a hospital for general myalgia, mild headache, and fever in October. He was noted to have thick, black papule skin on his abdomen, which was highly suggestive of scrub typhus. To confirm the diagnosis, O. tsutsugamushi antibody titers were examined and detected highly in serum by an indirect fluorescence antibody assay. Doxycycline, the standard treatment for scrub typhus, was administered. However, after seven days of treatment, he rapidly developed weakness in the right leg, paresthesia in both lower limbs, and voiding difficulty. Spinal magnetic resonance imaging (MRI) revealed lesions with high signal intensity involving the spinal cord at the thoracolumbar junction. Paraparesis gradually improved following steroid pulse therapy for five days. At one-year follow-up, he could walk without cane. Conclusions Orientia tsutsugamushi causes scrub typhus, which can affect not only the brain, but also the spinal cord. Although acute transverse myelitis develops rarely from scrub typhus, this should be considered as differential diagnosis in patients of fever with neurological deficit in endemic areas.

Abstract Background: Around 90% of sciatica cases are due to a herniated intervertebral disc in the lumbar region. Ankle acupuncture (AA) has been reported to be effective in the treatment of acute nonspecific low back pain. This study aims to evaluate the efficacy of a single session of ankle acupuncture for disc-related sciatica. Method: This will be a double-blinded, randomized controlled clinical trial. Patients diagnosed with disc-related sciatica will be randomly divided into 3 parallel groups. The treatment group (n = 30) will receive ankle acupuncture. The 2 control groups will either undergo traditional needle manipulation (n = 30) or sham acupuncture (n = 30) at the same point as the treatment group. The primary outcome will be pain intensity on a visual analog scale (VAS). The secondary outcomes will be paresthesia intensity on a VAS and the Abbreviated Acceptability Rating Profile (AAPR). The success of blinding will be evaluated, and the needle-induced sensation and adverse events will be recorded. All outcomes will be evaluated before, during, and after the treatment. Discussion: This study will determine the immediate effect and specificity of ankle acupuncture for the treatment of disc-related sciatica. We anticipate that ankle acupuncture might be more effective than traditional needle manipulation or sham acupuncture.

Panic disorder is a chronic and debilitating illness. In this article, we present an algorithm of the diagnosis and treatment of the illness. We place much importance upon the patient variables associated with the treatment decisions. We emphasize strong patient involvement in treatment as a way to become panic free and improve level of functioning. Panic disorder is defined in DSM-IV1 as "The presence of recurrent panic attacks followed by at least one month of persistent concern about having another panic attack, worry about the possible implications or consequences of the panic attack, or a significant behavioral change related to the attacks." A panic attack is defined as "a discrete period of intense fear or discomfort, in which four or more of the following symptoms developed abruptly and reached a peak within 10 minutes." 1) Palpitations, pounding heart or accelerated heart rate; 2) sweating; 3) trembling or shaking; 4) sensations of shortness of breath or smothering; 5) feeling of choking; 6) chest pain or discomfort; 7) nausea or abdominal distress; 8) feeling dizzy, unsteady, light-headed or faint; 9) derealization or depersonalization; 10) fear of losing control or going crazy; 11) fear of dying; 12) paresthesias; 13) chills or hot flashes. The following hypotheses have been used to conceptualize panic disorder from a psychiatrist's perspective.

The request for less-aggressive procedures to improve mandibular contour is increasing. Several kinds of threads have been used for this purpose. Nevertheless, PLLA (poly-L-Lactic acid) traction thread procedure has not been previously described. To investigate the role of PLLA traction threads in improving mandibular contour. Twenty women were enrolled in the study. They were differentially classified for skin laxity. Patients were treated in a single session with two PLLA traction threads per side. Specific post-procedure instructions were given to patients, and complications occurred after the procedures were estimated. A Fisher's t-test was performed to identify criteria related to longevity of results. We found longevity of results to be associated with younger age (p = 0.001), absence of severe skin laxity of jawline and neck (p = 0.001), and aesthetic satisfaction (p = 0.024). Edema, swelling, and temporary skin contour irregularities were found in most cases (N = 16; 80%), whereas paresthesia resolving without sequelae in 2-4 weeks was found in two cases (10%). Our results show that selected patients, younger than 51 and showing a mild-moderate degree of skin laxity of jawline and neck angle represent ideal candidates for PLLA traction thread treatment. Further studies will be performed to confirm our results.

Management of paclitaxel-induced neurotoxicity

Directory of Open Access Journals (Sweden)

Manisha Bhutani

Full Text Available Paclitaxel exerts its antitumor activity by promoting microtubule assembly and stabilizing microtubules. Microtubules are important for the development and maintenance of neurons. As a consequence, neurotoxicity is one of the drug’s major side effects. The risk of neurotoxicity depends on dose, duration and schedule of paclitaxel. Risk increases for patients with pre-existing conditions that may cause neuropathy (such as alcohol consumption, diabetes, or renal disease or with simultaneous or prior exposure to other neurotoxic chemotherapy such as platinum-based drugs, vinca alkaloids, immunomodulators, proteasome inhibitors, and epothilones. Patients with paclitaxel-induced neurotoxicity (PINT experience a constellation of symptoms over the course of treatment and beyond, ranging from mild to severe. Typically, the clinical presentation reflects an axonal peripheral neuropathy with glove-and-stocking distribution sensory loss, combined with features suggestive of nerve hyperexcitability including paresthesia, dysesthesia, and pain. Proprioceptive and motor effects become apparent as neuropathy becomes more advanced. These symptoms may be prolonged, severe, disabling, relatively resistant to intervention and adversely affect activities of daily living and thereby quality of life. Management is mainly symptomatic and supportive. Despite attempts to minimize PINT with changes in dose, vehicle, delivery systems, infusion schedule and premedication or co-treatment with neuroprotective agents, PINT remains dose-limiting in many instances and is a barrier to achieving the desired clinical response.

The authors describe a technical expedient applied during the removal of totally or partially impacted lower third molars, in order to prevent lingual nerve damage. EXPERIMENTAL ASSAY: Retrospective study. The sample includes 1835 extractions of totally or partially impacted lower third molars, performed on 1030 patients, 493 males and 537 females, aging between 12 and 72 years. All the operations were carried out under local anaesthesia with standardization of the surgical protocol. A mucoperiosteal paramarginal flap was used in case of germectomy, whereas a mucoperiosteal marginal flap with mesial releasing incision was used in case of fully mature teeth. Ostectomy and tooth sectioning were performed using a round and fissure bur respectively, assembled on a straight low-speed handpiece and under irrigation with sterile saline. The authors reported only one case of transient lingual nerve paresthesia (0.05%) which occurred in a 19-years old female presenting a totally impacted third molar mesial-lingual inclination. Symptoms disappeared spontaneously one week postoperatively. Therefore the overall incidence of permanent nerve damage was equal to 0%. The data reported in literature show a lingual nerve lesion incidence ranging between 0% and 22%. With this simple surgical expedient the incidence of permanent lingual damage was 0%. Thus, it is the authors' opinion that this simple expedient should be applied in all cases of impacted third molar removal.

A recent study showed that implant-prosthetic rehabilitation in well-controlled HIV patients gave slightly worse results than in an healthy population, and failures were all linked to infection. The aim of this study was to examine the associations between the success of implant-prosthetic treatment and systemic CD4+ level, smoking habits, and oral hygiene. This mono-centric study included HIV patients with a stable disease and good oral hygiene requiring implant rehabilitation. Each patient received at least one dental implant. Prosthesis were delivered after 90 days in the upper jaw and 60 days in the lower jaw. Primary outcome measures were prosthetic failures, implant failures, peri-implant marginal bone level changes, and biological complications (peri-implantitis, pus, pain, paresthesia). The possible association with CD4 count, smoking habits, and oral hygiene was analyzed. Sixty-eight patients received 194 implants, and 66 patients (190 implants) were followed for 1 year. No significant associations were found between CD4+ count, oral hygiene-associated variables, and any of the outcome measures. If compared with nonsmoking/light smoking patients, patients who smoked >10 cigarettes/day suffered a statistically significant greater number of implant failures (p ≤ .005), presented a comparatively higher number of peri-implantitis (p 10 cigarettes/day) demonstrated an increased risk of early implant failure, peri-implantitis, episodes of pus, and self-reported pain. © 2015 Wiley Periodicals, Inc.

Many studies worldwide have demonstrated the negative impact of an unhealthy built environment on citizens. In the case of diabetes, studies have concentrated on the environmental impact and accessibility issues of a place i.e. the home and neighborhood, whereas few studies have addressed the comfort of the type and spatial arrangement of a household and linked it with the prevalence of diabetes. Also, little research has tackled the place's impact on diabetic patients and their views concerning their environments. This paper demonstrates the outcomes of survey that was carried out on diabetic individuals who usually visit the King Fahd teaching hospital of the University of Dammam, Al-Khober, the Kingdom of Saudi Arabia (KSA). The patients were surveyed and physically examined. The present researchers found significant links between patients' diabetes symptoms such as reported paresthesia and blurred vision, and medical investigations results such as lipid profile, blood glucose and blood pressure with the environmental conditions of their homes and neighborhoods. The paper shows that the prevalence of the disease is not only caused by an unhealthy lifestyle but also by an unhealthy built environment. Moreover, it illustrates that unhealthy built environment promotes unhealthy life styles. It makes recommendations on how to improve the built environment in the KSA to be healthier for all citizens including the diabetic patients.

Full Text Available Objectives: The purpose of present article was to review aetiological factors, mechanism, clinical symptoms, and diagnostic methods as well as to create treatment guidelines for the management of inferior alveolar nerve injury during dental implant placement.Material and Methods: Literature was selected through a search of PubMed, Embase and Cochrane electronic databases. The keywords used for search were inferior alveolar nerve injury, inferior alveolar nerve injuries, inferior alveolar nerve injury implant, inferior alveolar nerve damage, inferior alveolar nerve paresthesia and inferior alveolar nerve repair. The search was restricted to English language articles, published from 1972 to November 2010. Additionally, a manual search in the major anatomy, dental implant, periodontal and oral surgery journals and books were performed. The publications there selected by including clinical, human anatomy and physiology studies.Results: In total 136 literature sources were obtained and reviewed. Aetiological factors of inferior alveolar nerve injury, risk factors, mechanism, clinical sensory nerve examination methods, clinical symptoms and treatment were discussed. Guidelines were created to illustrate the methods used to prevent and manage inferior alveolar nerve injury before or after dental implant placement.Conclusions: The damage of inferior alveolar nerve during the dental implant placement can be a serious complication. Clinician should recognise and exclude aetiological factors leading to nerve injury. Proper presurgery planning, timely diagnosis and treatment are the key to avoid nerve sensory disturbances management.

Cerebral Vasospasm with Ischemia following a Spontaneous Spinal Subarachnoid Hemorrhage

Full Text Available Cerebral vasospasm is a well-known consequence of aneurysmal subarachnoid hemorrhage (SAH triggered by blood breakdown products. Here, we present the first case of cerebral vasospasm with ischemia following a spontaneous spinal SAH. A 67-year-old woman, who was on Coumadin for atrial fibrillation, presented with chest pain radiating to the back accompanied by headache and leg paresthesias. The international normalized ratio (INR was 4.5. Ten hours after presentation, she developed loss of movement in both legs and lack of sensation below the umbilicus. Spine MRI showed intradural hemorrhage. Her coagulopathy was reversed, and she underwent T2 to T12 laminectomies. A large subarachnoid hematoma was evacuated. Given her complaint of headache preoperatively and the intraoperative finding of spinal SAH, a head CT was done postoperatively that displayed SAH in peripheral sulci. On postoperative day 5, she became obtunded. Brain MRI demonstrated focal restricted diffusion in the left frontoparietal area. Formal angiography revealed vasospasm in anterior cerebral arteries bilaterally and right middle cerebral artery. Vasospasm was treated, and she returned to baseline within 48 hours. Spontaneous spinal SAH can result in the same sequelae typically associated with aneurysmal SAH, and the clinician must have a degree of suspicion in such patients. The pathophysiological mechanisms underlying cerebral vasospasm may explain this unique case.

Ciguatoxins are the major toxins responsible for ciguatera fish poisoning, a disease dominated by muco-cutaneous sensory disorders including paresthesiae, cold dysesthesia and pruritus. While the ciguatoxins are well known to target voltage-gated sodium channels (VGSCs), the ensuing molecular mechanisms underlying these sensory disorders remain poorly understood. In this study, we propose a primary sensory neuron-keratinocyte co-culture as an appropriate model to study the neuro-cutaneous effects of ciguatoxins. Using this model, we show for the first time that nanomolar concentrations of Pacific ciguatoxin-2 (P-CTX-2) induced a VGSC-dependent release of substance P (SP) and calcitonin gene-related peptide (CGRP). As these neuropeptides are known mediators of pain and itch sensations, the ciguatoxin-induced sensory disturbances in ciguatera fish poisoning may involve the release of these neuropeptides. We further determined time- and P-CTX-2 concentration-dependence of the release of SP and CGRP from the co-culture model. Moreover, we highlighted the influence of extracellular calcium on the release of neuropeptides elicited by P-CTX-2. These findings underline the usefulness of this novel in vitro model for studying the cellular and molecular mechanisms of the neuro-cutaneous effects of ciguatoxins, which may assist with identifying potential therapeutics for ciguatera fish poisoning.

Chronic venous disease (CVD) is an important clinical condition with substantial epidemiological implications and socio-economic repercussions. In the Western world the consequences of its high prevalence, the costs of diagnosis and therapy, the significant loss of working hours and the repercussions on patients'quality of life are well known. Pharmacotherapy for CVD has greatly developed over the last 40 years and largely used in the symptomatic treatment of CVD together with compression therapy and to make patients more comfortable. The clinical efficacy on the symptoms (feeling of heaviness, pain, paresthesia, heat and burning sensations, night cramps, etc.) has long been confirmed by Level III, IV and V evidence, but there are now Level I and II trials on specific drugs. For the bioflavonoids double-blind, randomised trials have used micronized purified flavonoid fraction; rutosides; escin; anthocyanosides; and synthetic calcium dobesilate. It was therefore surprising some recent difficulties in the use of this important treatment in health national system in Italy. In this up-date we use the method on evidence-based medicine from the medical literature. We have started a governance and economic analysis of the problem in Italy. Particular consideration was given to the evidence set out in review, meta-analysis, guidelines and Consensus Statements in this field. The evidence for pharmacological agents in the treatment of CVD suggests today a wide use in all CEAP classes.

Atypical Central Neurocytoma with Recurrent Spinal Dissemination over a Period of 20 Years: A Case Report and Review of the Literature

Tareq A. Juratli

2013-01-01

Full Text Available We present an unusual case of a late recurrent central neurocytoma that was rediagnosed as an ependymoma and neurocytoma in accordance with changes in histological classifications. Case Description. A 56-year-old male teacher presented with incomplete transverse syndrome due to several intradural extramedullary tumors at the level of lumbar vertebrae 1–3. The histological diagnosis at the time was atypical ependymoma. One year later, two additional tumors were removed at the L5-S1 vertebral level. For 12 years, the patient remained tumor free on followup. Fourteen years after the initial diagnosis, the patient presented with thoracic paresthesias due to two new extramedullary tumors in the C7-T1 and the T8-T9 vertebral levels. After complete removal of the tumors, a radiological survey revealed an intracranial lesion in the third ventricle. Five months later, an additional lesion recurrence was removed surgically. The most recent histological diagnosis revealed an atypical central neurocytoma. In retrospect, the previous tumors were reclassified as neurocytoma according to the additional immunohistochemistry evidence. Discussion. There is no standard adjuvant treatment regimen for atypical neurocytoma; therefore, the patient is currently under close followup. Modern histopathological diagnosis is essential in these cases. Potential routes for dissemination of the tumor should be considered upon first recurrence.

The clinical symptoms of myelopathy are variable and non-specific. Demyelinating as well as neoplastic spinal cord diseases can cause paresthesia, progressive sensomotoric deficits and bowel and bladder dysfunction. Imaging of the spine, especially with magnetic resonance imaging (MRI), is an essential component in the diagnostic assessment of myelopathy and makes a substantial contribution to achieving the correct diagnosis. Although intramedullary neoplasms are far less common than demyelinating spinal cord diseases, radiologists should be familiar with the three most common entities, astrocytoma, ependymoma and hemangioblastoma, which represent over 70% of all spinal cord neoplasms. An early diagnosis and therapy is essential with neoplastic and demyelinating spinal cord diseases to hold residual neurological deficits as low as possible. (orig.) [German] Die klinische Symptomatik von Myelopathien ist aeusserst variabel und unspezifisch. Sowohl demyelinisierende als auch tumoroese Rueckenmarkerkrankungen koennen Paraesthesien, progrediente sensomotorische Ausfaelle und eine Sphinkterdysfunktion hervorrufen. Bildgebende Untersuchungen, und hier allen voran die MRT, sind ein unerlaesslicher Bestandteil zur Abklaerung von Myelopathien und tragen wesentlich zur korrekten Diagnose bei. Intramedullaere Tumoren sind zwar weitaus seltener als demyelinisierende Rueckenmarkerkrankungen, dennoch sollte der Radiologe mit den Bildmerkmalen der 3 haeufigsten Tumorarten, dem Astrozytom, Ependymom und Haemangioblastom vertraut sein, die ueber 70% aller Rueckenmarktumoren verursachen. Eine moeglichst fruehe Diagnostik und Therapie sind bei tumoroesen und demyelinisierenden Rueckenmarkerkrankungen essenziell, um bleibende neurologische Defizite moeglichst gering zu halten. (orig.)

Full Text Available Infection with human T cell lymphotropic virus type I (HTLV-I causes multiple neurologic disorder , due to the retroviruses.Spinal cord disease of this type is named TSP (tropical spastic paraparesis that were drawn to the attention of neurologists 45 years ago. The clinical picture is one of the slowly progressive paraparesis with increased tendon reflexes & Babinski signs ; disorder of sphincteric control is usually an early change. Paresthesia , reduced vibratory & position senses, & ataxia have been described. The diagnosis is confirmed by the detection the antibodies to the virus in serum . There are anecdotal reports of improvement with IV-administration of gammaglobulin. But HTLV1-infection has other clinical manifestations. This report presents a rare case with bilateral facial weakness as primary manifestation. This case is related to a 41 years old woman. The clinical picture was bilateral facial weekness and approximately after 2 months, she referred to hospital with myelitis. In primary exams and evaluation, the diagnose was HTLV-I infection. The diagnosis was confirmed by the detection of the antibodies against the virus in her serum. She dead after 2.5 months of the first sign due to disease severity and bulbar palsy. Possible transmission routes and the risk of encountering the disease outside endemic areas must be attended , and it is recommended to evaluate antibodies in the children of the patients.

A 25-year-old male complained of intermittent, sharp pains about the left eye and in the left side of the chest. Neurological examination revealed paresthesia and impaired perception of touch and pin-pricks in the dermatomes of Th8 and Th9 on the left side. In all four extremities, the muscle stretch reflexes were equal and slightly hyperactive, without weakness or sensory deficits. Metrizamide myelography showed defective filling at the level between the upper 8th and 9th thoracic vertebrae. The lesion was also demonstrated by computed tomography (CT) scan performed 1 hour later, appearing as an oval, radiolucent mass in the left dorsal spinal canal, which compressed the spinal cord forward and toward the right. Serial sections of the spinal canal revealed the lesion to be partly filled with contrast medium. Repeat CT scan 24 hours after metrizamide myelography showed more contrast medium in the periphery of the lesion, giving it a doughnut-shaped appearance. At surgery a smooth-surfaced cyst containing sebum and white hair was totally removed from the intradural extramedullary space. The histological diagnosis was dermoid cyst. There have been a few reported cases of intracranial epidermoid cyst in which filling of the cyst was suggested on metrizamide CT myelography. These findings may complicate the differential diagnosis of arachnoid cyst and dermoid or epidermoid cyst when only CT is used.

Ultrasound-Guided Interscalene Catheter Complicated by Persistent Phrenic Nerve Palsy

Directory of Open Access Journals (Sweden)

Andrew T. Koogler

2018-01-01

Full Text Available A 76-year-old male presented for reverse total shoulder arthroplasty (TSA in the beach chair position. A preoperative interscalene nerve catheter was placed under direct ultrasound-guidance utilizing a posterior in-plane approach. On POD 2, the catheter was removed. Three weeks postoperatively, the patient reported worsening dyspnea with a subsequent chest X-ray demonstrating an elevated right hemidiaphragm. Pulmonary function testing revealed worsening deficit from presurgical values consistent with phrenic nerve palsy. The patient decided to continue conservative management and declined further invasive testing or treatment. He was followed for one year postoperatively with moderate improvement of his exertional dyspnea over that period of time. The close proximity of the phrenic nerve to the brachial plexus in combination with its frequent anatomical variation can lead to unintentional mechanical trauma, intraneural injection, or chemical injury during performance of ISB. The only previously identified risk factor for PPNP is cervical degenerative disc disease. Although PPNP has been reported following TSA in the beach chair position without the presence of a nerve block, it is typically presumed as a complication of the interscalene block. Previously published case reports and case series of PPNP complicating ISBs all describe nerve blocks performed with either paresthesia technique or localization with nerve stimulation. We report a case of a patient experiencing PPNP following an ultrasound-guided placement of an interscalene nerve catheter.

Full Text Available OBJECTIVE: Carpal tunnel syndrome (CTS is defined as median nerve entrapment within the carpal tunnel at the wrist. Pain and paresthesia are the most common presenting symptoms of the patients. In this study, our aim was to identify the association between intensity of presenting symptoms and electrophysiologic findings in patients referred to the electrophysiology laboratory with prediagnosis of CTS. METHODS: Sixty-two consecutive patients who were referred to the electrophysiology laboratory with the diagnosis of CTS were enrolled in the study. The intensity of pain was determined by visual analog scale, the findings of Tinel-Phalen tests were assessed, and clinico-demographic findings were recorded. Nerve conduction studies were performed bilaterally in median and ulnar nerves. The severity of CTS was determined with electrophysiologic evaluation, and the association between electrophysiologic findings and symptoms were analyzed statistically. RESULTS: Sixty-two (57 female, 5 male patients were examined in the study. CTS was bilateral in 53 patients and unilateral in 9 patients (total 115 hands. Mean pain score was 5.78 ± 3.50. In 28 hands with a clinical diagnosis of CTS, no electrophysiologic CTS findings were found, whereas in 32 hands mild, in 41 hands moderate and in 14 hands severe findings were obtained. CONCLUSION: According to our study, there was no statistically significant association between severity of symptoms and severity of electrophysiologic findings in CTS

Eight patients (seven males and one female) were suffering from over-irradiation syndrome as a result of treatments from a malfunctioning linear electron accelerator. The mean accidental estimated dose was 136 Gy delivered to the ''open-neck'' (seven cases) and to the thoracic wall (one case), during a mean of 5.4 sessions (range 1-9 sessions). Paresthesia and weakness in the upper extremities were the earliest symptoms (87.5 %), with evolution to paralysis in all patients. No patient is alive (mean survival time 64 days). In all cases MRI was negative for neurologic lesions in the acute phase (< 90 days from irradiation; Radiation Therapy Oncology Group scoring system). Late signs of radiation myelitis manifested as high-intensity signals on T2-weighted images in three patients, and as Gd-DTPA enhancement of T1-weighted images in one case. Autopsies performed on four patients who died in acute phase showed morphologic alterations in white matter: edema in 75 %, and necrosis and glial reaction as well as obliterative vasculitis in all cases. In cases of over-irradiation, MRI may be normal in acute phase even if the patients have severe neurologic deficit, as positive MRI findings appear only in delayed radiation myelitis. (orig.).

The purpose of this study was to assess the efficacy of image-guided radiofrequency (RF) ablation of cystic renal tumors. Between November 2005 and August 2007, computed tomography (CT) or ultrasound-guided RF ablation was performed in nine patients with 14 Bosniak category III (n = 5) or IV (n = 9) cystic renal tumors using an internally cooled RF ablation system. We evaluated the number of sessions, cycles and duration of energy application, treatment results, lesion size change, and complications. Together the cystic renal tumors required 15 sessions and 23 cycles of energy application. The duration of energy application per one tumor ablation ranged from 1 to 12 min (mean 6 min). The last follow-up CT indicated complete coagulation of 14/14 (100%) lesions. None of these tumors had recurred within 1-19 months (mean 8 months). The maximum diameter of the cystic renal tumors was significantly reduced from 2.5 {+-} 0.6 cm before ablation to 1.7 {+-} 0.7 cm at the last follow-up CT (P < 0.01). Complications were pneumothorax (n = 2), inguinal paresthesia (n = 1), and arteriovenous fistula (n = 1). Image-guided RF ablation is an effective treatment for Bosniak category III or IV cystic renal tumors, which might need relatively shorter duration of energy application than purely solid renal tumors of the same size.

Full Text Available OBJECTIVE: To assess the impact of multiple sclerosis (MS on the professional life of Brazilian patients. METHOD: One hundred MS patients were randomly selected from the database of the Brazilian Multiple Sclerosis Association (ABEM. An individual interview was carried out by telephone by a member of ABEM, who collected data on the patients' clinical status, educational level and professional lives. RESULTS: Complete data were obtained from 96 patients (27 males and 69 females aged 55.0±14.1 years, with average disease duration of 4.6±4.0 years. Eighty percent had eleven or more years of schooling. Among the whole group, 66% did not present limitations on walking. The longer the disease duration and the older the patient were, the higher the chances were that the patient was retired or receiving workers' compensation benefits. However, even among patients with MS for less than five years, the rate of non-participation in the workforce was 47.7%. Fatigue, paresthesia, cognitive dysfunction and pain were often cited as the motives for not working. CONCLUSION: MS patients presented high levels of unemployment, retirement and receipt of workers' compensation benefits, despite their high schooling levels. Age, disease duration and disability influenced these results for the whole group. However, even among younger patients with shorter disease duration and low disability, this finding remained.

Primary Intradural Hemangiopericytoma With Intramedullary Invasion

Full Text Available Hemangiopericytoma (HPC is a rare tumor of the central nervous system and is usually found intracranially. Intraspinal HPCs are very rare and mostly involve the extradural bony structures. Primary intradural HPC has only been reported in 10 cases, all of which occurred in the extramedullary region. Intramedullary invasion has never been reported. Here, we describe a case of primary intradural HPC of the thoracic spine that presented initially with paresthesia and paraplegia of both legs. Magnetic resonance imaging of the thoracic spine showed an intradural dumbbell-shaped tumor at the T10 level. The initial impression was neurogenic tumor, meningioma, or metastasis. During operation, the tumor was found to have obvious intramedullary invasion. Gross-total removal was done, and the patient's neurological function improved; there was no recurrence at the 3-year follow-up. There is no consensus as to what constitutes the optimal treatment of HPC, but most neurosurgeons will advocate gross-total resection. A comparative analysis between intradural and extradural HPCs showed a higher chance of gross-total resection for intradural HPCs, while the recurrence rates showed no difference. The role of adjuvant radiotherapy remains uncertain. Due to the high risk of recurrence and metastasis of HPCs, close follow-up for a long period is mandatory. [J Chin Med Assoc 2009;72(10:536–541

Full Text Available Petrous apex lesions of temporal bone progress slowly. Most of the time not only destruct this area but also involve neighbouring element. The symptoms of the neighbouring neuro-vasculare involvement we can recognize these lesions. The most common symptoms of involvement of the petrous apex are: headache, conductive hearing loss or sensorineural type, paresthesia and anesthesia of the trigeminal nerve, paresia and paralysis of the facial nerve, abducent nerve. In retrospective study which has been in the ENT and HNS wards of Amiralam hospital, 148 patients have been operated due to temporal bone tumor; from these numbers, 21 (13.6% patients had petrous apex lesions of temporal bone. Eleven (52.9% patients of these 21 persons were men and the remaining 10 (47-6% were women. The average age of the patients was 37 years. The common pathology of these patients were glomus jugulare tumors, hemangioma, schwannoma, meningioma, congenital cholesteatoma, giant cell granuloma. The kind of operations that have been done on these patients were: infratemporal, translabyrinthine and middle fossa approaches. The conclusion of this study shows that petrous apex area is an occult site. The symptoms of this lesion are not characteristic, meticulous attention to the history and physical examination are very helpful to recognition of these lesions and it's extention.

Peripheral nerve block is an accepted method in lower limb surgeries regarding its convenience and good tolerance by the patients. Quick performance and fast sensory and motor block are highly demanded in this method. The aim of the present study was to compare 2 different methods of sciatic and tibial-peroneal nerve block in lower limb surgeries in terms of block onset. In this clinical trial, 52 candidates for elective lower limb surgery were randomly divided into 2 groups: sciatic nerve block before bifurcation (SG; n = 27) and separate tibial-peroneal nerve block (TPG; n = 25) under ultrasound plus nerve stimulator guidance. The mean duration of block performance, as well as complete sensory and motor block, was recorded and compared between the groups. The mean duration of complete sensory block in the SG and TPG groups was 35.4 ± 4.1 and 24.9 ± 4.2 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). The mean duration of complete motor block in the SG and TPG groups was 63.3 ± 4.4 and 48.4 ± 4.6 minutes, respectively, which was significantly lower in the TPG group (P = 0.001). No nerve injuries, paresthesia, or other possible side effects were reported in patients. According to the present study, it seems that TPG shows a faster sensory and motor block than SG.

Erectile dysfunction and amatorial cycling.

Today cycling is considered a useful form of exercise for reducing cardiovascular risk, but it may also represent a risk factor for erectile dysfunction and perineal-genital paresthesia. These disorders are attributed to the local reduction of oxygen in the perineal-genital area, secondary to the perineal compression. Numerous studies have been carried out measuring the penile oxygen pressure or penile blood flow by echo-colour-Doppler: a reduced inflow of blood and oxygen to the cavernous tissue was demonstrated. The attention of the specialist is therefore concentrated on the compression of the perineum on the bicycle saddle and how to reduce this through the position of the cyclist on the bicycle (i.e. height and tilt of the saddle), the different shapes of saddle available (i.e. noseless, grooved, wide, etc.) and the padding materials of the saddle. In order to reduce perineal compression, the posterior part of the saddle should be as wide as the distance between the two ischiatic tuberosities. In addition, the saddle should be studied on the basis of the biotype of the cyclist: ectomorphic, mesomorphic or endomorphic. However, in the genesis of the erectile dysfunction of the cyclist, apart from the above-mentioned factors, an "individual predisposition to developing erectile dysfunction" linked to the perineal-genital anatomy (i.e. type of insertion of the perineum into the root of the penis, number of layers of the tunica albuginea of the corpus cavernosum) cannot be excluded.

The present study was undertaken to evaluate the efficacy of biodegradable plating system for fixation of maxillofacial fractures and to study the morbidity associated with the use of biodegradable plates and screws. This prospective study consisted of 10 patients with maxillofacial fractures requiring open reduction and internal fixation. Fractures with infection, comminuted and pathological fractures were excluded. All were plated with biodegradable system (Inion CPS) using standard plating principles and observed for a total period of 24 weeks. Characteristics of the fractures, ease of use of bioresorbable plate/screw system and post operative complications were assessed. Of total 10 patients, eight patients were of midface fracture and two pediatric patients with mandibular fracture, with nine male and one female. The mean age was 32.8 years. Out of 20 plates and 68 screws applied to the 10 fractures sites; there were three incidences of screw breakage with no other intraoperative difficulties. Paresthesia of the infraorbital nerve was present in two patients, and recovered completely in four weeks after surgery. Fracture reduction was considered to be satisfactory in all cases. One patient developed postsurgical infection and was managed with oral antibiotics and analgesics. Favorable healing can be observed through the use of biodegradable plates and screws to stabilize selected midface fractures in patients of all ages, as well as mandible fractures in early childhood, however further studies with more sample size are required.

Decompression sickness (DCS) in humans is associated with reductions in ambient pressure that occur during diving, aviation, or certain manned spaceflight operations. Its signs and symptoms can include, but are not limited to, joint pain, radiating abdominal pain, paresthesia, dyspnea, general malaise, cognitive dysfunction, cardiopulmonary dysfunction, and death. Probabilistic models of DCS allow the probability of DCS incidence and time of occurrence during or after a given hyperbaric or hypobaric exposure to be predicted based on how the gas contents or gas bubble volumes vary in hypothetical tissue compartments during the exposure. These models are calibrated using data containing the pressure and respired gas histories of actual exposures, some of which resulted in DCS, some of which did not, and others in which the diagnosis of DCS was not clear. The latter are referred to as marginal DCS cases. In earlier works, a marginal DCS event was typically weighted as 0.1, with a full DCS event being weighted as 1.0, and a non-event being weighted as 0.0. Recent work has shown that marginal DCS events should be weighted as 0.0 when calibrating gas content models. We confirm this indication in the present work by showing that such models have improved performance when calibrated to data with marginal DCS events coded as non-events. Further, we investigate the ramifications of derating marginal events on model-prescribed air diving no-stop limits. Copyright © 2017 Elsevier Ltd. All rights reserved.

Around 90% of sciatica cases are due to a herniated intervertebral disc in the lumbar region. Ankle acupuncture (AA) has been reported to be effective in the treatment of acute nonspecific low back pain. This study aims to evaluate the efficacy of a single session of ankle acupuncture for disc-related sciatica. This will be a double-blinded, randomized controlled clinical trial. Patients diagnosed with disc-related sciatica will be randomly divided into 3 parallel groups. The treatment group (n = 30) will receive ankle acupuncture. The 2 control groups will either undergo traditional needle manipulation (n = 30) or sham acupuncture (n = 30) at the same point as the treatment group. The primary outcome will be pain intensity on a visual analog scale (VAS). The secondary outcomes will be paresthesia intensity on a VAS and the Abbreviated Acceptability Rating Profile (AAPR). The success of blinding will be evaluated, and the needle-induced sensation and adverse events will be recorded. All outcomes will be evaluated before, during, and after the treatment. This study will determine the immediate effect and specificity of ankle acupuncture for the treatment of disc-related sciatica. We anticipate that ankle acupuncture might be more effective than traditional needle manipulation or sham acupuncture. ChiCTR-IPR-15007127 (http://www.chictr.org.cn/showprojen.aspx?proj=11989).

A prospective MRI study of 39 whiplash patients was performed and the results were compared with the clinical findings within 15 days after trauma. The MRI parameters included disc bulging either with impingement on the anterior epidural space or with medullary compression, foraminal stenosis, dorsal ligament thickening, osteophyte extension and intramedullary or paravertebral soft tissue injury. All changes were graded visually on a four-point scale (no, some, moderate or extensive changes). After the MRI evaluation was made the clinical findings were analysed by two orthopaedic surgeons using a specially designed protocol. With MRI 29 patients (74 %) showed no or only slight changes, and were thus regarded as normal variations. Of these, 10 of 29 patients (34 %) had as the only symptom pain in the head or in the neck, 19 of 29 patients (66 %) showed neurological changes, either paresthesias, sensory deficits or weakness of upper extremities. In 10 (26 %) patients with moderate or extensive MRI changes, 3 of 10 (33 %) had only head or neck pain, or both, and 7 of 10 (66 %) had neurological changes. Use of MRI in whiplash injury is helpful, but it is not the first-choice radiological examination method. Despite neurological changes, the frequency of true traumatic lesions is low. There is no clear correlation between the patients` subjective symptoms or clinical signs and the findings with MRI. However, MRI can be used to find patients with disk herniation that can be treated surgically. (orig.)

A 1-year-old dog ingested a mixture of blood agar and Mycoplasma agar plates. The Mycoplasma agar plates contained thallium acetate, which resulted in an estimated minimum dose of 5 mg thallium acetate/kg bodyweight. Clinical signs over the course of 2-3 weeks included vomiting, diarrhea, weight loss, alopecia, dysphonia, ataxia, paresthesia, intension tremors, megaesophagus with subsequent aspiration pneumonia, and several seizure episodes. The dog was treated with intravenous fluids and placement of a gastric feeding tube. Thallium concentrations in hair were 8.2 µg/g in samples taken on day 19, 16.4 µg/g in samples taken 3 months after exposure, 13.4 µg/g in samples taken 5 months after exposure, and nondetectable in samples taken 7 months after exposure. The blood thallium concentration was 190 µg/l on day 19 and nondetec table 3 months after exposure. Megaesophagus and dysphonia continued for 10 months after exposure. This case of thallium poisoning following ingestion of mycoplasma agar plates demonstrates that unusual sources of thallium still exist and suggests that thallium toxicosis should be included in the list of differential diagnoses in dogs presented with megaesophagus, especially if alopecia and other unexplained peripheral neuropathies are present. Hair and blood samples are useful specimens to reach an accurate diagnosis even if taken several weeks post exposure. The postexposure blood and hair thallium concentrations reported in this case are useful data for diagnosticians investigating dogs with potential thallium poisoning.

2015-01-01

High-frequency stimulation (HFS) has recently gained attention as an alternative to parameters used in traditional spinal cord stimulation (SCS). Because HFS is paresthesia free, the gate theory of pain control as a basis of SCS has been called into question. The mechanism of action of HFS remains unclear. We compare the effects of HFS and traditional SCS on quantitative sensory testing parameters to provide insight into how HFS modulates the nervous system. Using quantitative sensory testing, we measured thermal detection and pain thresholds and mechanical detection and pressure pain thresholds, as well as vibratory detection, in 20 SCS patients off stimulation (OFF), on traditional stimulation (ON) and on HFS in a randomized order. HFS significantly increased the mechanical detection threshold compared to OFF stimulation (p < 0.001) and traditional SCS (p = 0.01). Pressure pain detection and vibratory detection thresholds also significantly increased with HFS compared to ON states (p = 0.04 and p = 0.01, respectively). In addition, HFS significantly decreased 10- and 40-gram pinprick detection compared to OFF states (both p = 0.01). No significant differences between OFF, ON and HFS states were seen in thermal and thermal pain detection. HFS is a new means of modulating chronic pain. The mechanism by which HFS works seems to differ from that of traditional SCS, offering a new platform for innovative advancements in treatment and a greater potential to treat patients by customizing waveforms. © 2015 S.

Aim: The aim of this study is to compare piezoelectric surgery versus rotatory osteotomy technique in removal of mandibular impacted third molar. Materials and Methods: Sample size of 30 patients 18 males, 12 females with a mean age of 27.43 ± 5.27. Bilateral extractions were required in all patients. All the patients were randomly allocated to two groups in one group, namely control group, surgical extraction of mandibular third molar was done using conventional rotatory osteotomy and in the other group, namely test group, extraction of lower third molar was done using Piezotome. Results: Parameters assessed in this study were – mouth opening (interincisal opening), pain (visual analog scale VAS score), swelling, incidence of dry socket, paresthesia and duration of surgery in both groups at baseline, 1st, 3rd, and 7th postoperative day. Comparing both groups pain scores with (P piezosurgery group (51.40 ± 17.9) minutes compared to the conventional rotatory group with a mean of (37.33 ± 15.5) minutes showing a statistically significant difference (P = 0.002). Conclusion: The main advantages of piezosurgery include soft tissue protection, optimal visibility in the surgical field, decreased blood loss, less vibration and noise, increased comfort for the patient, and protection of tooth structures. Therefore, the piezoelectric device was efficient in decreasing the short-term outcomes of pain and swelling although taking longer duration than conventional rotatory technique it significantly reduces the associated postoperative sequelae of third molar surgery.

The potential danger of eating wild lettuce: a brief review of human rat lungworm infection.

Science.gov (United States)

Ewers, Evan C; Anisowicz, Sarah K

2014-11-01

Angiostrongylus cantonensis, the causative agent of human rat lungworm disease, is the most common cause of eosinophilic meningitis worldwide and is endemic throughout Asia Pacific. It is acquired through the consumption of infected freshwater mollusks or contaminated produce. Human angiostrongyliasis is usually a self-limited disease presenting with headache and various neurologic sequelae varying from cranial nerve palsies to radiculitis and/or paresthesias. Fatal cases are rare, and manifest as fulminant meningomyeloencephalitis. The diagnosis is made through the use of clinical history, exam, and laboratory data including peripheral blood counts, cerebrospinal fluid (CSF) examinations, and serologic or molecular diagnostic techniques. Medical therapy is largely focused on symptomatic relief, and includes analgesics, lumbar puncture, and corticosteroids. In resource-limited settings, prevention is key, and the use of analgesics can provide symptomatic relief after infection. Efforts to increase disease awareness have been made in endemic areas, as evidenced by the recent Rat Lungworm Disease Scientific Workshop which was held in Honolulu in 2011. The proceedings of the workshop were published in a supplement to this journal (Hawaii J Med Public Health. Jun 2013;72(6):Supp 2). However, wilderness medicine and travel medicine specialists must also be aware of the disease, how it is contracted, its presentation, and treatment options should they encounter a patient who is in or has returned from an endemic area. This brief review highlights eosinophilic meningitis caused by A. cantonensis, including an example case, an overview of its clinical presentation, treatment options, and prevention.

Full Text Available Abstract Background Fibromyalgia syndrome displays sympathetically maintained pain features such as frequent post-traumatic onset and stimuli-independent pain accompanied by allodynia and paresthesias. Heart rate variability studies showed that fibromyalgia patients have changes consistent with ongoing sympathetic hyperactivity. Norepinephrine-evoked pain test is used to assess sympathetically maintained pain syndromes. Our objective was to define if fibromyalgia patients have norepinephrine-evoked pain. Methods Prospective double blind controlled study. Participants: Twenty FM patients, and two age/sex matched control groups; 20 rheumatoid arthritis patients and 20 healthy controls. Ten micrograms of norepinephrine diluted in 0.1 ml of saline solution were injected in a forearm. The contrasting substance, 0.1 ml of saline solution alone, was injected in the opposite forearm. Maximum local pain elicited during the 5 minutes post-injection was graded on a visual analog scale (VAS. Norepinephrine-evoked pain was diagnosed when norepinephrine injection induced greater pain than placebo injection. Intensity of norepinephrine-evoked pain was calculated as the difference between norepinephrine minus placebo-induced VAS scores. Results Norepinephrine-evoked pain was seen in 80 % of FM patients (95% confidence intervals 56.3 – 94.3%, in 30 % of rheumatoid arthritis patients and in 30 % of healthy controls (95% confidence intervals 11.9 – 54.3 (p Conclusions Fibromyalgia patients have norepinephrine-evoked pain. This finding supports the hypothesis that fibromyalgia may be a sympathetically maintained pain syndrome.

Carboxytherapy may generate local pain that is considered the main limiting factor in clinical practice. Transcutaneous electric nerve stimulation (TENS) is widely used in the control of acute pain; however, the effect of TENS on pain relief during carboxytherapy has not been studied to date. To assess the effect of TENS on pain intensity during carboxytherapy in patients with cellulite in the gluteal region. This randomized clinical trial was conducted with 84 patients, 18-44 years of age, who had moderate cellulite in the gluteal region, according to Cellulite Severity Scale, but never received carboxytherapy. Patients were randomized into 3 groups: active TENS, placebo TENS, and control group. For the intervention, skin depressions with cellulite were outlined, and the gluteal area to be treated was defined. The subcutaneous injection of CO 2 was performed using 0.30 × 13 mm-needles at a 45° angle, with a controlled flow rate of 100 mL/min maintained for 1 minute at each puncture site. The parameters for TENS were as follows: frequency of 100 Hz and pulse duration of 200 μs; TENS intensity was adjusted until the patient reported strong paresthesia. The visual numeric pain rating scale was used to assess pain intensity after each puncture. The active TENS group reported lower pain intensity compared to the placebo TENS (P TENS) was effective in reducing pain intensity during carboxytherapy in patients with cellulite in the gluteal region. © 2018 Wiley Periodicals, Inc.

While contraindications to Essure® placement have been provided by the manufacturer, there is no consensus on how best to remove these contraceptive devices. Here, we describe a non-hysterectomy removal of Essure® for a patient with a septate uterus (ESHRE Class IIb uterine malformation). A 35yr old G4 P2 presented for removal of Essure® implants after three years of gradually increasing pelvic pain, weight gain, headache, dizziness, lower extremity paresthesia, and fatigue which followed hysteroscopic sterilization (HS). Prior to HS, the patient was in good general health. She did not smoke and had never had a miscarriage. HS was performed under general anesthesia in October 2012. HSG obtained three months later, confirmed bilateral tubal occlusion but revealed an abnormal uterine cavity. A repeat HSG in 2015 showed minimal device migration, no contrast dye spill and a deeply bifid uterine cavity. At our center laparoscopic cornual dissection and bilateral partial tubal resection achieved removal of both devices intact and the patient was discharged three hours after surgery. Her postoperative recovery was uneventful. The presence of a Müllerian anomaly is a relative contraindication to the Essure® procedure. This is the first reported description of successful removal of Essure® coils in the setting of an ESHRE Class IIb uterine anomaly, and underscores the importance of careful patient selection, accurate pre-operative imaging and a conservative technique which renders hysterectomy unnecessary.

Full Text Available Introduction: Attention Deficit Hyperactivity Disorder (ADHD is the most common behavioral issue for children. One of the sleeping disorders most frequently related to ADHD is the Restless Legs Syndrome (RLS, characterized by an irresistible urge to move the legs, something that is generally associated with paresthesias and motor restlessness. The prevalence rate of RLS in children diagnosed with ADHD is close to 18%, but in Colombia, these cases have been hardly studied. Objective: To determine the frequency of RLS, in children with ADHD. Methods: A cross-sectional study, filled out by parents of children diagnosed with ADHD, were analyzed. This questionnaire contained clinical criteria for classifying ADHD according to the DSM-IV, as well as diagnostic criteria for RLS by the National Institutes of Health (2003. Results: A predominance rate of 65.6% in combined ADHD was observed in children with RLS criteria. Upon carrying out an exploratory data analysis, it was found that having a family history of RLS and belonging to the middle or low socioeconomic strata are conditions associated with the presence of RLS in children with ADHD, with a significant p (p < 0.000 and a PR of 4.47 (3.16-6.32. Conclusions: The prevalence of RLS was similar to the findings of other clinical investigations. However, it highlights new prevalence values in relation to the comorbidity between ADHD and RLS, suggesting the need for new clinical and therapeutic alternatives amidst the presence of both syndromes.

The aim of this study was to evaluate the efficacy of thermal therapy, in particular hydromassage therapy with the ''Ca' Rossa'' salsobromoiodic water of the Thermae Oasis (Ferrara, Italy), in patients with chronic venous insufficiency (CVI) of the inferior limbs. Fourty-four patients with primary varices of the legs were enrolled. The anamnestic symptomatologic indicators of disease were: pain, perception of heaviness or paresthesias, nocturnal cramps, ''restless leg'' syndrome, pruritus. The symptoms were evaluated for both intensity and frequency. An additional clinical indicator was the centimetric measurement of the leg diameters at 3 levels: supramalleolar, mid-calf and mid-thigh. The patients were subdivided in two groups: patients submitted to a cycle of hydromassage with salsobromoiodic water and patients treated with compressive elastic stocking (12 mmHg). At the end of the treatment cycle, symptomatologic and clinical data were reassessed, in addition to morphological and velocimetric parameters related to the function of the peripheral vascular system. The results showed in Group A (thermal water hydromassage) an improved reduction of subjective and objective symptoms as compared to the control Group B, demonstrating a superior efficacy of thermal therapy. The efficacy of hydromassage therapy is due not only to the favourable action of hydrostatic pressure upon venous flow of the inferior limbs, but also to the peculiar chemical and physical characteristics of the thermal water utilized in this study. The elevated osmotic power of hydromassage is responsible for the significant intrinsic antiedematous properties.

Nondrug-related aspect of treating Ekbom disease, formerly known as restless legs syndrome

Full Text Available Ulrike H MitchellDepartment of Exercise Sciences, Brigham Young University, Provo, UT, USAAbstract: Ekbom disease (EKD, formerly known as restless legs syndrome (RLS has affected and bothered many people over the centuries. It is one of the most prevalent neurological disorders in Europe and North-America, affecting about 10% of the population. The main characteristics are the strong urge to move, accompanied or caused by uncomfortable, sometimes even distressing, paresthesia of the legs, described as a "creeping, tugging, pulling" feeling. The symptoms often become worse as the day progresses, leading to sleep disturbances or sleep deprivation, which leads to decreased alertness and daytime functions. Numerous studies have been conducted assessing the efficacy of dopaminergic drugs, opioids, and other pharmacologic agents in alleviating EKD symptoms. However, there is also a growing body of evidence demonstrating the effectiveness of nonpharmacologic treatments including life style changes, physical activity programs, pneumatic compression, massage, near-infrared light therapy, and complementary therapies. The working mechanisms behind these alternatives are diverse. Some increase blood flow to the legs, therefore reducing tissue hypoxia; some introduce an afferent counter stimulus to the cortex and with that "close the gate" for aberrant nerve stimulations; some increase dopamine and nitric oxide and therefore augment bio-available neurotransmitters; and some generate endorphins producing an analgesic effect. The advantages of these treatments compared with pharmacologic agents include less or no side effects, no danger of augmentation, and less cost.Keywords: RLS, modalities, massage, intermittent compression, NIR

2018-02-01

Full Text Available Background Tolosa–Hunt syndrome (THS related neurological symptoms are described in literature as “unilateral”, “recurrent”, “episodic”, “intense”, “severe”, “lancinating” or “stabbing” pain on the upper face and forehead and may be misdiagnosed due to the similarity of few symptoms and a significant number of common characteristics between both conditions. Aims The aim of this brief report is to indicate some important clinical insights related to Tolosa Hunt syndrome, and to give a frank account on the multidisciplinary approach on neurological-related symptomatology in maxillofacial region. Methods We analysed a selection of patients with such clinical picture. To better describe the proper management of clinical cases, we report a 50-year-old female reporting an history of two years of recurrent, severe stabbing pain around the right eye, prominence of her cheek and forehead. Her general dentist first mistakenly diagnosed toothache and, thus, it was subsequently misdiagnosed the trigeminal neuropathy (TN. Results Reported exemplificative case presented a mild ptosis, diplopia of the right eye, corneal reflex loss, paresthesia and hyperesthesia of upper part of left side of face. Magnetic resonance imaging (MRI findings were suggestive of THS. Complete resolution of symptoms was achieved with oral Prednisolone and constant monitoring of symptoms. Conclusion THS may be added to the long list of differential diagnosis of TN and general dentist and oral surgeons should be informed about such rare causes of facial pain through continued medical education programs.

Seventeen patients with stage IA non-Hodgkin's lymphoma of the Waldeyer's ring were treated with radiation therapy with or without chemotherapy. All lesions were judged as having intermediate grade malignancy in the Working Formulation. Eight patients received combined treatment with three cycles of cylcophosphamide, doxorubicin, vincristine and prednison (CHOP) and radiation therapy with 30 to 40 Gy. Another 9 patients were treated with radiation therapy 40 to 60 Gy alone. After a median follow-up of 69 months, all 8 patients, treated with combined modality were alive and relapse-free whereas 4 of the 9 treated with irradiation alone had relapsed. All relapses occurred transdiaphragmatically. Two of the 4 relapsing patients were saved, but the other two died of the disease. The 5-year relapse-free and cause-specific survival rates were 100% and 100% in the combined modality group, and 56% and 76% in the radiation therapy alone group (relapse-free: p=0.04, cause-specific: p=0.16). There were no serious complications related to treatment, although most patients complained of mouth dryness and most patients given CHOP had paresthesia. Our opinion was that the total impact of these two side-effects on quality of life was less pronounced after combined modality than after radiation therapy alone. Limited chemotherapy and radiation therapy seemed to be more beneficial than radiation therapy alone not only in relapse-free survival but also in quality of life after treatment. (orig.)

The aim of the study was to evaluate the sympathectomy procedures for primary hyperhidrosis in terms of complications and effectiveness. From January 2010 to September 2012 we performed 130 sympathectomies in 65 patients, 27 males (42%) and 38 females (58%). Electrocoagulation was used in 20 procedures (15%), ultrasonic scalpel in 54 (42%), and radiofrequency dissector in 56 (43%). Seven patients (11%) underwent bilateral sympathectomy in the same surgical session, while in 58 (89%) the right surgical approach was delayed 30 days from the first procedure. We noticed 12 complications (9%): (a) chest pain in 6 patients (4 with electrocoagulation, 1 with ultrasonic scalpel, and 1 with radiofrequency dissector), which disappeared in 20 ± 1 day; (b) paresthesias in 3 electrocoagulation patients, was solved in 23 ± 5 days; (c) bradycardia in 1 ultrasonic patient, normalized in 4th postoperative hour; (d) unilateral relapse in 2 electrocoagulation patients after the second side approach, positively treated in 1 patient by resurgery in video-assisted thoracoscopy (VAT). The quality-adjusted life year and the quality of life evaluation revealed a statistically significant improvement (p = 0.02) in excessive sweating and general satisfaction after surgery, with Ultracision and LigaSure showing better findings than electrocoagulation. The latest generation devices offered greater efficacy in the treatment of hyperhidrosis, minimizing complications and facilitating the resumption of normal work and social activity of patients.

We report a case of a 62-year-old postmenopausal hypertensive lady who was treated for osteoporosis with calcium and Vitamin D. She presented with progressive lower limb weakness and paresthesia with sensory level at T4. Investigations revealed high parathyroid hormone 1152 ng/dl, calcium 10.9 mg/dl, and low phosphorus of 2.4 mg/dl after stopping calcium supplement. Chest x-ray showed an expansile mass lesion of the right 6th rib confirmed by chest CT. Thoracic MRI showed a mass lesion extending from the T3 vertebral body and compressing the spinal cord. There were multiple lytic lesions of the scalp, ribs, femur, and pelvis suggesting metastatic lesions. A neck ultrasound and SESTA MIBI parathyroid scan confirmed a right lower parathyroid adenoma. Excision biopsy of the rib lesion confirmed a vascular lesion with features of brown tumor BT. Decompression surgery of the thoracic spine was performed, and the histopathology confirmed BT. Two weeks later the patient underwent right parathyroidectomy that proved to be a parathyroid adenoma. She showed a remarkable improvement in her clinical condition and there were some regression of the bony lesions observed 12 months post parathyroidectomy. This case should alert physicians to the association of multiple brown tumors in PHPT and that the presentation may be an aggressive one mimicking metastasis, patients with osteoporosis warrant at least calcium profile to rule out a secondary cause.

1995-01-01

A prospective MRI study of 39 whiplash patients was performed and the results were compared with the clinical findings within 15 days after trauma. The MRI parameters included disc bulging either with impingement on the anterior epidural space or with medullary compression, foraminal stenosis, dorsal ligament thickening, osteophyte extension and intramedullary or paravertebral soft tissue injury. All changes were graded visually on a four-point scale (no, some, moderate or extensive changes). After the MRI evaluation was made the clinical findings were analysed by two orthopaedic surgeons using a specially designed protocol. With MRI 29 patients (74 %) showed no or only slight changes, and were thus regarded as normal variations. Of these, 10 of 29 patients (34 %) had as the only symptom pain in the head or in the neck, 19 of 29 patients (66 %) showed neurological changes, either paresthesias, sensory deficits or weakness of upper extremities. In 10 (26 %) patients with moderate or extensive MRI changes, 3 of 10 (33 %) had only head or neck pain, or both, and 7 of 10 (66 %) had neurological changes. Use of MRI in whiplash injury is helpful, but it is not the first-choice radiological examination method. Despite neurological changes, the frequency of true traumatic lesions is low. There is no clear correlation between the patients' subjective symptoms or clinical signs and the findings with MRI. However, MRI can be used to find patients with disk herniation that can be treated surgically. (orig.)

We report a case who developed internuclear ophthalmoplegia as a result of a closed head injury. A CT scan (Delta scan 50 FSII) demonstrated a small hemorrhage (9 x 12 mm. on actual measurement) in the dorsum of the upper pons. The patient is a 40-year-old male who fell backward while chasing a fly ball, striking the back of the head. He was rendered unconcious for some ten minutes. Upon admission, mild impairment of the adduction of both eye-balls was noted; 10 hours later this became more obvious, along with cerebellar ataxia, mild dysarthria, and paresthesia of the face. A CT scan obtained immediately after admission revealed an area of increased density compatible with a hemorrhage in the dorsum of the upper pons. A follow-up CT scan on the 12th hospital day revealed a complete resolution of the initially noted high-density in the upper pons, and 2 weeks following admission, the above-noted signs started to improve. Two and a half months following the injury he returned to work as a printer, although a detailed neuro-otological examination done 29 months after the injury still demonstrated evidence of bilateral internuclear ophthalmoplegia. To the author's knowledge, only 13 cases of traumatic 'MLF syndrome' have been reported so far, and our case is the first in which a CT scan indeed demonstrated the lesion. The details of the case are presented, along with the results of the neuro-otological evaluation. (author)

The purpose of this study was to evaluate the compound nerve action potential amplitude and latency measured to determine the degree of myelination and the number of fibers stimulated in a model of stimulated frog sciatic nerve laser at 810 nm as perioperative treatment after injury. It used 30 bullfrogs (Rana catesbeiana) to obtain 60 sciatic nerves forming four groups, groups 1 and 2 worked with nerves in vitro, were dissected in humid chambers for placing isolated organ, was recorded on compound nerve action potential, the second group laser was applied at 24, 48, 72, 96 and 120 hours and at the same time were placed in 10% formalin. Groups 3 and 4 are worked in vivo localizing the nerve and causing damage through compression, occurred over the compound nerve action potential to assess the degree of myelination and the number of fibers stimulated, the group 4 was applied to 810 nm laser (500 Hz, 10 J, 200 mW) after injury, after 48 hours, three frogs were sacrificed by introducing the nerves in 10% formalin. The latency recorded by stimulating the sciatic nerve of frog to 0.5 mA and 100 ms in groups 1 and 2 show significant differences (p 000), as to the extent, if any statistically significant difference. (p<0.001 and p<0.000). The laser produces a favorable response in the treatment of paresthesia (post-traumatic neuropathy).

Objective: To explore the clinical significance of retrograde access for the interventional treatment of lower extremity arterial occlusive diseases when the occluded segment of lower extremity artery could not be reached through antegrade access. Methods: Twenty-seven cases (male 17, female 10; age range 32-89 years) were retrospectively investigated, including 18 with lower limb arteriosclerosis obliterans, 7 with diabetic foot and 2 with thromboangiitis obliterans. According to the Fontaine staging, 6 cases were classified as Fontaine Ⅱ, 11 were classified as Fontaine Ⅲ and 10 were classified as Fontaine Ⅳ. All cases underwent endovascular operation through antegrade access first with an attempt to cross the occlusive segment, but in vain. So retrograde access was tried via puncture of pedis dorsalis or posterior tibial artery or exposure of lateral branches of posterior tibial artery, peroneal artery or dorsal artery by open surgery,which followed by Percutaneous transluminal angiography and (or) stenting. Results: The operation through retrograde access was successful in all cases with obvious improvement of ischemic symptoms. Hematoma at the puncture site occurred in 3 patients, and paresthesia of toes occurred in 1 after dorsalis pedis arteriotomy. No severe perioperative complication occurred. The average ankle brachial index increased from 0.37 ± 0.11 preoperatively to 0.85 ± 0.12 postoperatively. Conclusions: Retrograde access could be used as an alternative strategy in lower extremity arterial occlusive diseases when the occluded segment could not reach through antegrade access. (authors)

An Occult Malignancy Behind a Demyelinating Disease

Full Text Available We report a case of a 38-year-old man presenting with bilateral lower extremity weakness and paresthesias that progressed during a 4-month period to severe polyneuropathy forcing the patient to be bed bound. Throughout his multiple hospitalizations, he was treated erroneously for chronic inflammatory demyelinating polyneuropathy, without significant improvement in his symptoms. In addition, he developed hepatosplenomegaly (organomegaly; endocrinopathies such as diabetes mellitus, central hypogonadism, and hypothyroidism; monoclonal spike evidenced in the serum electrophoresis; and hyperpigmentation of skin, altogether consistent with POEMS syndrome. During his last hospitalization he developed excruciating pain on his left hip, and imaging revealed the presence of a 9 × 6 cm osteolytic mass with sclerotic rim in the left acetabulum. Biopsy of the mass confirmed an isolated IgG lambda plasmacytoma. The patient received radiation to his left acetabular lesion followed by left hip replacement. Subsequently, the patient underwent autologous bone marrow transplant. Eighteen months after his initial presentation, he had satisfactory clinical response and is functional without significant limitations. POEMS syndrome is a rare paraneoplastic syndrome secondary to an underlying plasma cell disorder, which can oftentimes be overlooked and misdiagnosed. The median age of presentation is 51 years, and only 31% of the cases occur in fairly young patients under the age of 45 as evidenced in this case. As clinicians, we should be aware of the constellation of features associated with POEMS syndrome and be able to recognize them promptly.

Fabry disease related patients with classical mutation usually exhibit similar severe phenotype especially concerning renal manifestation. A dry blood spot screening (DBS) and the DNA analysis has been performed in a 48-year-old man (Patient 1) because of paresthesia. The DBS revealed absent leukocyte α -Gal A enzyme activity while DNA analysis identified the I354K mutation. Serum creatinine and e-GFR were in normal range and also albuminuria and proteinuria were absent. The brain MRI showed ischemic lesions and a diffuse focus of gliosis in the white matter, while the echocardiogram showed a left ventricular hypertrophy. The renal biopsy performed in the case index showed a massive deposition of zebra bodies. By a familiar investigation, it was recognized that his brother (Patient 2) died 2 years before from sudden death syndrome at the age of 49. He had suffered sporadic and undiagnosed pain at the extremities, a prior cataract, bilateral neurosensorial hearing loss and left ventricular hypertrophy on Echocardiogram. His previous laboratory examinations revealed a normal serum creatinine and the absence of proteinuria. Pedigree analysis of the brothers revealed a high disease burden among family members, with an affected cousin (Patient 3) who progressed early to end-stage renal disease (ESRD) that required renal transplantation. Here we describe the clinical history of three adult male members of the same family with the same genotype who manifested different presentation and progression of the disease, particularly concerning the renal involvement.

2016-06-01

We sought to report the successful surgical management of a case of ecchordosis physaliphora (EP) using a neuro-endoscopic trans-third ventricular approach (ETTVA) and to provide a current review of literature on EP. A 57-year-old man presenting with a 2-year history of diplopia due to right abducens nerve palsy and paresthesia of the left body underwent magnetic resonance imaging, which revealed a retroclival intracisternal lesion. The cystic lesion was considered to be most likely EP according to neuroradiologic features. The patient underwent an endoscopic trans-third ventricular resection. A pediatric endoscope was passed from a precoronal burr hole through the left lateral into the third ventricle. The floor of the third ventricle was opened by a 2-micron laser. This approach permitted us to expose the lesion in the retroclival cistern and follow up with a subtotal removal. Remnants of the capsule, which were firmly adherent to small pontine arteries and the left abducens nerve, were left. Histology confirmed EP. The patient recovered well from surgery, and symptoms regressed at clinical follow-up. The endoscopic approach for third ventriculostomy can also be used for the surgical management of retroclival lesions. However, a small pediatric endoscope with an angled view, which can be passed through the floor of the third ventricle without causing harm, is mandatory to explore all important structures in the narrow surgical space. Limitations in this delicate environment are firm adhesions to vessels and nerves because only 1-instrument manipulation is possible and bleeding must be avoided. Copyright © 2016 Elsevier Inc.

Ipilimumab (a monoclonal antibody against CTLA-4) and nivolumab (a humanized antibody against PD-1) target these immune checkpoint pathways and are used for treatment of melanoma and an increasing number of other cancers. However, they may cause immune-related adverse effects (IRAEs). Although many endocrinopathies are known to be IRAEs, primary hypoparathyroidism with severe hypocalcemia has never been reported. This is the first case of hypoparathyroidism as an IRAE presenting to an Emergency Department with acute hypocalcemia. A 73-year-old man with metastatic melanoma presented to the Emergency Department for the chief complaints of imbalance, general muscle weakness, abdominal pain and tingling in extremities. He had wide spread metastasis, and begun immunotherapy with concurrent ipilimumab and nivolumab 1.5months ago. At presentation, he had ataxia, paresthesia in the hands and feet, and abdominal cramping. Magnetic resonance imaging of the brain was unremarkable. He was found to be hypocalcemic with undetectable plasma parathyroid hormone. He was admitted for treatment of symptomatic hypocalcemia and was diagnosed with primary hypoparathyroidism. Shortly afterwards, he had thyrotoxicosis manifesting as tachycardia and anxiety, followed by development of primary hypothyroidism. At 4months after the Emergency Department visit, his parathyroid function and thyroid function had not recovered, and required continued thyroid hormone replacement and calcium and vitamin D treatment for hypocalcemia. Primary hypoparathyroidism caused by ipilimumab and nivolumab may acute manifest with severe symptomatic hypocalcemia. Emergency care providers should be aware of hypoparathyroidism as a new IRAE in this new era of immuno-oncology. Copyright © 2017 Elsevier Inc. All rights reserved.

[First ciguatera outbreak in Germany in 2012].

2016-12-01

In November 2012, 23 cases of ciguatera with typical combinations of gastrointestinal and neurological symptoms occurred in Germany after consumption of imported tropical fish (Lutjanus spp.). A questionnaire was used to gather information on the disease course and fish consumption. All patients suffered from pathognomonic cold allodynia. Aside from two severe courses of illness, all other cases showed symptoms of moderate intensity. During a three-year follow-up, seven patients reported prolonged paresthesia for more than one year. Two of them reported further neuropathies over almost three years. This is the first time that long-term persistence of symptoms has been documented in detail. Outbreak cases were allocated to eight clusters in seven German cities. A further cluster was prevented by the successful recall of ciguatoxic fish. Three clusters were confirmed by the detection of ciguatoxin in samples of suspicious and recalled fish. An extrapolation on the basis of ciguatoxic samples revealed twenty prevented cases of ciguatera. Further officially unknown cases should be assumed. During the outbreak investigations, inadvertently falsely labelled fish species and fishing capture areas on import and retail level documents were observed. The ascertainment of cases and the outbreak investigations proved to be difficult due to inconsistent case reports to poisons centers, local health and veterinary authorities. In Germany, many physicians are unaware of the disease pattern of ciguatera and the risks caused by tropical fish. The occurrence of further outbreaks during the following years emphasizes the increasing significance of ciguatera in Germany.

Yusho is a mass food poisoning that was caused by ingestion of rice oil contaminated with dioxins and related organochlorines in 1968. Patients with Yusho suffer from skin symptoms (acneform eruptions, liability to suppuration and pigmentation, respiratory symptoms (cough and expectoration of sputum, neurological symptoms (numbness and paresthesia of extremities, arthralgia and general fatigue, and no effective treatment has yet been developed. In this clinical trial, four Kampo formulae (Bakumondo-to, Keigai-rengyo-to, Gosha-jinki-gan and Hochu-ekki-to were administered to four representative Yusho symptoms (respiratory, skin, neurological symptoms and general fatigue, respectively. Twenty-seven Yusho patients were enrolled and two formulae were administered to each patient for half-a-year each. The effectiveness of Kampo formulae was estimated by changes in the intensity of symptoms measured by a visual analogue scale (VAS of 100 mm recorded at baseline and after administration of each formula. The influence of Kampo formulae on patients’ quality of life (QOL was also assessed by the SF-36 (NBS. Twenty-five patients completed the treatment. Bakumondo-to significantly improved respiratory symptoms as well as patients’ QOL in the context of vitality, compared with other formulae. In contrast, Hochu-ekki-to impaired patients’ QOL in the context of physical functioning and vitality, compared with other formulae. This study demonstrated for the first time that a Kampo formula Bakumondo-to is useful for treating respiratory symptoms caused by dioxins.

Bariatric surgery is considered to be the most effective treatment of morbid obesity and improvement of obesity-related comorbidities, such as type II diabetes. However, both peripheral and central neurological complications can occur after bariatric surgery. Such complications tend to occur more frequently after bypass surgery than after sleeve gastrectomy (SG). The objective of this study was to identify the patients that presented post-operative neurological complications after undergoing SG and describe the incidence, presentation, and management of these complications. This was a retrospective study of 592 cases of SG performed between 2009 and 2014 with a special focus on patients who presented neurological complications. Of the 592 SG cases, only seven (1.18 %) patients presented neurological complications. All patients had uneventful post-operative course, but all reported feeding difficulties, accompanied by severe dysphagia, and rapid weight loss, with a mean weight loss of 35 kg (30-40 kg) 3 months after SG. All patients were readmitted owing to neurological symptoms that included paresthesia, abolition of deep tendon reflexes of the lower limbs, muscle pain, and motor and sensitive deficits in some cases. There were two cases of Wernicke's encephalopathy. All patients were treated for neuropathy secondary to vitamin B1 deficiency and had a significant improvement and/or resolution of their symptoms. Neurological complications after SG are rare and are often preceded by gastrointestinal symptoms, rapid weight loss, and lack of post-operative vitamin supplementation. Re-hospitalization and multidisciplinary team management are crucial to establish the diagnosis and initiate treatment.

In this prospective study, 13 randomly selected patients underwent treatment for zygomatic-complex fractures (2 site fractures) and mandibular fractures using 1.5 / 2 / 2.5-mm INION CPS biodegradable plates and screws. To assess the fixation of zygomatic-complex and mandibular fractures with biodegradable copolymer osteosynthesis system. In randomly selected 13 patients, zygomatic-complex and mandibular fractures were plated using resorbable plates and screws using Champy's principle. All the cases were evaluated clinically and radiologically for the type of fracture, need for the intermaxillary fixation (IMF) and its duration, duration of surgery, fixation at operation, state of reduction at operation, state of bone union after operation, anatomic reduction, paresthesia, occlusal discrepancies, soft tissue infection, immediate and late inflammatory reactions related to biodegradation process, and any need for the removal of the plates. Descriptives, Frequencies, and Chi-square test were used. In our study, the age group range was 5 to 55 years. Road traffic accidents accounted for the majority of patients six, (46.2%). Postoperative occlusal discrepancies were found in seven patients as mild to moderate, which resolved with IMF for 1-8 weeks. There were minimal complications seen and only as soft tissue infection. Use of biodegradable osteosynthesis system is a reliable alternative method for the fixation of zygomatic-complex and mandibular fractures. The biodegradable system still needs to be refined in material quality and handling to match the stability achieved with metal system. Biodegradable plates and screws is an ideal system for pediatric fractures with favorable outcome.

Temple and Postauricular Dissection in Face and Neck Lift Surgery

Directory of Open Access Journals (Sweden)

Joo Heon Lee

2017-07-01

Full Text Available Periauricular paresthesia may afflict patients for a significant amount of time after facelift surgery. When performing face and neck lift surgery, temple and posterior auricular flap dissection is undertaken directly over the auriculotemporal, great auricular, and lesser occipital nerve territory, leading to potential damage to the nerve. The auriculotemporal nerve remains under the thin outer superficial fascia just below the subfollicular level in the prehelical area. To prevent damage to the auriculotemporal nerve and to protect the temporal hair follicle, the dissection plane should be kept just above the thin fascia covering the auriculotemporal nerve. Around the McKinney point, the adipose tissue covering the deep fascia is apt to be elevated from the deep fascia due to its denser fascial relationship with the skin, which leaves the great auricular nerve open to exposure. In order to prevent damage to the posterior branches of the great auricular nerve, the skin flap at the posterior auricular sulcus should be elevated above the auricularis posterior muscle. Fixating the superficial muscular aponeurotic system flap deeper and higher to the tympano-parotid fascia is recommended in order to avoid compromising the lobular branch of the great auricular nerve. The lesser occipital nerve (C2, C3 travels superficially at a proximal and variable level that makes it vulnerable to compromise in the mastoid dissection. Leaving the adipose tissue at the level of the deep fascia puts the branches of the great auricular nerve and lesser occipital nerve at less risk, and has been confirmed not to compromise either tissue perfusion or hair follicles.

The objective of this case report is to describe the use of transverse tripolar dorsal column stimulation in a patient with a history of irritable bowel syndrome (IBS) associated with abdominal pain resistant to conservative treatments. We report a 36-year-old man who presented to the pain clinic with an eight-year history of IBS (constipation predominant with occasional diarrheal episodes), with "crampy and sharp" abdominal pain. He also had nonradicular thoracic spine pain due to thoracic scoliosis. Both pains were affecting his ability to function as an attorney. Prior conservative therapy, including psychologic treatment, antidepressants, and opioids, was without any benefits. The use of a spinal cord stimulator (SCS) was discussed with the patient. The procedure was performed after Institutional Review Board approval. A tripolar SCS was implanted at the T8 level using one-eight contact and two-four contact percutaneous leads based on paresthesia reproduction of patient's areas of discomfort. This tripolar spinal cord stimulation provided relief of abdominal and thoracic pain, and better management of gastrointestinal symptoms. The patient was followed-up for one year, and his quality of life also was improved via the IBS-Severity Scoring System quality of life tool. The use of the tripolar SCS in this patient provided relief of abdominal and thoracic spine pain, regulated bowel habits, and improved the patient's quality of life. We believe that the use of SCS should be considered as a treatment option in patients with IBS when all conservative treatments failed. © 2012 International Neuromodulation Society.

Purpose: We assessed clinical outcome and long-term tumor control after fractionated stereotactic radiotherapy (FSRT) for unilateral schwannoma. Methods and Materials: Between 1995 and 2007, 496 patients were treated with fractionated stereotactic radiotherapy at Johns Hopkins Hospital (Baltimore, MD); 385 patients had radiologic follow-up that met the inclusion criteria. The primary endpoint was treatment failure. Secondary endpoints were radiologic progression and clinical outcome. Logistic regression analysis assessed the association of age, race, tumor side, sex, and pretreatment symptoms. Results: In 11 patients (3%) treatment failed, and they required salvage (microsurgical) treatment. Radiologic progression was observed in 116 patients (30.0%), including 35 patients (9%) in whom the treatment volume more than doubled during the follow-up period, although none required surgical resection. Tumors with baseline volumes of less than 1 cm 3 were 18.02 times more likely to progress than those with tumor volumes of 1 cm 3 or greater (odds ratio, 18.02; 95% confidence interval, 4.25-76.32). Treatment-induced neurologic morbidity included 8 patients (1.6%) with new facial weakness, 12 patients (2.8%) with new trigeminal paresthesias, 4 patients (0.9%) with hydrocephalus (1 communicating and 3 obstructive), and 2 patients (0.5%) with possibly radiation-induced neoplasia. Conclusions: Although the rate of treatment failure is low (3%), careful follow-up shows that radiologic progression occurs frequently. When reporting outcome, the 'no salvage surgery needed' and 'no additional treatment needed' criteria for treatment success need to be complemented by the radiologic data.

First-episode psychosis as the initial presentation of multiple sclerosis: a case report.

Enderami, Athena; Fouladi, Rose; Hosseini, Seyed Hamzeh

2018-01-01

Multiple sclerosis (MS) is an inflammatory disease that affects the central nervous system (CNS). MS with episode of psychosis is a rare entity, and to the best of our knowledge, no case has been reported from Iran till date. We report a case of MS with first-episode psychosis in a 27-year-old single man with no history of psychiatric disorder or drug abuse. The patient developed neurological symptoms after 3 months and was finally diagnosed as a case of MS. His symptoms started with behavioral dysfunctions and progressively resulted in depression. Subsequently, treatment was performed with citalopram 20 mg daily, risperidone 2 mg three times a day, and biperiden 2 mg three times a day; however, no improvements in the symptoms were observed. T2-weighted magnetic resonance imaging has demonstrated periventricular and white matter multiple sclerotic plugs with lesions. Eventually, MS was diagnosed after the appearance of paresthesia, upper and lower limb muscle weakness, ataxia, and urinary incontinency as typical signs. Then, the medications were changed to methylprednisolone and interferon therapy, which resulted in improvements in the clinical conditions of the patient. Based on the fact that organic disorders such as MS may sometimes appear with initial pure psychiatric symptoms without any neurological signs and symptoms, examinations for symptoms linked to CNS dysfunction, cognitive changes, atypical symptoms, detailed neurological examination, and limited response to conventional antipsychotic drugs are highly recommended to be carried out for patients with first-episode psychosis and even in the followup period.

A cross-sectional study. Neuropathic pain (NP) after spinal cord injury (SCI) tends to be hard to treat, and its heterogeneous properties make it difficult to identify and characterize. This study was conducted to assess the characteristics of SCI-related NP in detail. A single hospital for SCI rehabilitation. This study included 72 patients who were seen at our hospital in 2012 and 2013 and who had sustained SCI at least 3 months before enrollment. The patients completed the Neuropathic Pain Symptom Inventory (NPSI) and the Short Form (SF)-36 Health Inventory. The NPSI score was analyzed for correlations with clinical presentations of SCI and SF-36 subitems. Paresthesia/dysesthesia was the most common subtype of NP after SCI. With regard to location, below-level superficial NP was significantly more intense than at-level pain. Patients who underwent surgery showed significantly less evoked pain compared with patients with non-surgery. Patients reported significantly more severe pain if >1 year had elapsed after the SCI. Patients with an American Spinal Injury Association Impairment Scale grade of B for completeness of injury reported more intense NP than those with other grades. Among the SF-36 subitems, NP correlated significantly with bodily pain, general health and mental health. NP in SCI patients was significantly associated with the location of pain, the time period since the injury, surgery and quality-of-life factors. A more detailed understanding of the characteristics of NP may contribute to better strategies for relieving the pain associated with SCI.

We followed eight hereditary motor and sensory neuropathy patients with proximal dominance (HMSN-P) in Shiga prefecture from 1984 to 2007. There were 4 men and 4 women from two families showing autosomal and dominant prepotency. These families were related by marriage. The average onset of disease was at 53.4 +/- 8.9 (40-68) years-old. Initial symptoms were difficulty of standing up, difficulty elevating their arms, limping, or numbness. The main feature was neurogenic muscular atrophy with proximal dominance. All deep tendon reflexes were decreased or nonexistent. Paresthesia in the hands and feet and/or decreased vibratory sense in the legs were found in six patients. High CK blood levels were recognized in three patients. EMG in four patients revealed neurogenic pattern. Nerve conduction study was conducted in two patients. MCV of the median nerve and of the tibial posterior nerve, also SCV of the median nerve and of the sural nerve were within normal range in all nerves. Amplitudes of sensory action potential or of M wave were decreased or nonexistent in five of eight nerves, and distal latency of M waves was delayed in three of four nerves. These data suggests dysfunction of distal parts of the peripheral nerve fibers and axonal degeneration of the nerve trunk. Seven patients have died, and their average death age was 69.1 +/- 8.2 (52-77) years-old. Their average affected period was 16.6 (4-30) years. Their clinical history resembles Okinawa-type HMSN-P, but without the painful muscle cramps which are distinctive Okinawa-type signs.

Patients with anophthalmic or phthisis socket suffer from cosmetic problems. To resolve those problems, the authors present the surgical outcomes of deep superior sulcus (DSS) augmentation using acellular dermal matrix in patients with anophthalmic or phthisis socket. The authors retrospectively reviewed anophthalmic or phthisis patients who underwent surgery for DSS augmentation using acellular dermal matrix. To evaluate surgical outcomes, the authors focused on 3 aspects: the possibility of wearing contact prosthesis, the degree of correction of the DSS, and any surgical complications. The degree of correction of DSS was classified as excellent: restoration of superior sulcus enough to remove sunken sulcus shadow; fair: gain of correction effect but sunken shadow remained; or fail: no effect of correction at all. Ten eyes of 10 patients were included. There was a mean 21.3 ± 37.1-month period from evisceration or enucleation to the operation for DSS augmentation. All patients could wear contact prosthesis after the operation (100%). The degree of correction was excellent in 8 patients (80%) and fair in 2. Three of 10 (30%) showed complications: eyelid entropion, upper eyelid multiple creases, and spontaneous wound dehiscence followed by inflammation after stitch removal. Uneven skin surface and paresthesia in the forehead area of the affected eye may be observed after surgery. The overall surgical outcomes were favorable, showing an excellent degree of correction of DSS and low surgical complication rates. This procedure is effective for patients who have DSS in the absence or atrophy of the eyeball.

Multinodular and vacuolating neuronal tumor (MVNT) have been recently added to the WHO classification of CNS tumors and has not been extensively reported upon in the radiological literature. We report the first radiological and the largest series of cases, aiming to highlight the natural history of lesions with the imaging appearance of MVNT with long follow-up time. In this retrospective study, we collected cases with the imaging appearance of MVNT. All lesions were evaluated by using routine MR imaging, with follow-up of up to 93 months. Patient demographics, clinical course, and MRI features of the lesions were recorded. Twenty-four subjects were enrolled, f/m = 16:8, age range 24-59 years, with a median age of 45 years. The patients' symptoms were often episodic and most frequently due to headaches in 12 (50%), visual symptoms in 6 (25%), seizures in 5 ± 1 (20-25%), paresthesia in 4 (∝17%), cognitive difficulties in 4 (∝17%), in addition to other variable neurological symptoms, or incidental. A total of 30 lesions identified, 77% of the lesions had gadolinium-enhanced MRI and only 13% showed enhancement. A 6.7% of the lesions that had MRI followed up showed progression, while the rest remained stable up to 93 months interval. All patients had intact neurological examinations (except one case that was diagnosed with optic neuritis), were managed conservatively, and did well. The natural history of lesions with imaging features of MVNT is overall stable from a clinical and imaging appearance over time. (orig.)

Phantom limb pain (PLP) is a neuropathic condition in which pain is perceived as arising from an amputated limb. PLP is distinct from, although associated with, pain in the residual limb and nonpainful phantom sensations of the missing limb. Its treatment is extremely challenging; pharmaceutical options, while commonly employed, may be insufficient or intolerable. Neuromodulatory interventions such as spinal cord stimulation have generated mixed results and may be limited by poor somatotopic specificity. It was theorized that dorsal root ganglion (DRG) neuromodulation may be more effective. Patients trialed a DRG neurostimulation system for their PLP and were subsequently implanted if results were positive. Retrospective chart review was completed, including pain ratings on a 100-mm visual analogue scale (VAS) and patient-reported outcomes. Across eight patients, the average baseline pain rating was 85.5 mm. At follow-up (mean of 14.4 months), pain was rated at 43.5 mm. Subjective ratings of quality of life and functional capacity improved. Some patients reduced or eliminated pain medications. Patients reported precise concordance of the paresthesia with painful regions, including in their phantom limbs; in one case, stimulation eliminated PLP as well as nonpainful phantom sensations. Three patients experienced a diminution of pain relief, despite good initial outcomes. DRG neuromodulation may be an effective tool in treating this pain etiology. Clinical outcomes in this report support recent converging evidence suggesting that the DRG may be the site of PLP generation and/or maintenance. Further research is warranted to elucidate mechanisms and optimal treatment pathways. © 2015 International Neuromodulation Society.

A 67-year-old woman with asthma visited our hospital with increasing dyspnea and new-onset paresthesia and purpura in her legs. Physical examination showed a wheeze, pretibial edema, and surrounding purpura. Chest X-rays showed cardiac decompensation and an electrocardiogram revealed a new ST-T change. Laboratory data showed leukocytosis, hypereosinophilia (10,450/μL), troponin T(+), elevated BNP, and markedly elevated eosinophil cationic protein (ECP) (> 150 ng/mL). Echocardiography revealed diffuse left ventricular hypokinesis (ejection fraction 30%) with increased wall thickness. Coronary angiography was normal. Cardiac magnetic resonance imaging implied diffuse myocardial edema and subendocardial late gadolinium enhancement. Skin biopsy of purpura showed superfi cial perivascular dermatitis with remarkable eosinophilic infiltrations. No evidence of drug allergies, parasitic infection, or myeloproliferative disorder was detected. Based on these findings, a diagnosis of eosinophilic myocarditis due to Churg-Strauss syndrome was considered. She was administered prednisolone at a dose of 1 mg/kg, cyclophosphamide, and diuretics. Several markers of eosinophilic myocarditis and heart failure gradually improved, including ECP. She was discharged 30 days later with no cardiac event. Eosinophilic myocarditis is characterized by predominantly eosinophilic infi ltration. Eosinophilic granule proteins, such as ECP and major basic protein, play important roles in the pathogenesis of eosinophilic myocarditis. We experienced a rare case of eosinophilic myocarditis due to Churg-Strauss syndrome. Markedly elevated ECP played an important role in the early diagnosis and subsequent reduction in ECP served as a marker of monitoring. In an asthmatic patient with dyspnea, hypereosinophilia, and vasculitis, Churg-Strauss syndrome with eosinophilic myocarditis should be considered.

Background Coronectomy is the surgical removal of the crown of the tooth deliberately leaving part of its roots. This is done with the hope of eliminating the pathology caused, and since the roots are still intact, the integrity of the inferior alveolar nerve is preserved. Objectives The aim is to carry out a systematic review in order to be able to provide results and conclusions with the greatest scientific evidence possible. Material and Methods A literature review is carried out through the following search engines: Pubmed MEDLINE, Scielo, Cochrane library and EMI. The level of evidence criteria from the Agency for Healthcare Research and Quality was applied, and the clinical trials’ level of quality was analyzed by means of the JADAD criteria. Results The following articles were obtained which represents a total of 17: 1 systematic review, 2 randomized clinical trials and 2 non-randomized clinical trials, 3 cohort studies, 2 retrospective studies, 3 case studies and 4 literature reviews. Conclusions Coronectomy is an adequate preventative technique in protecting the inferior alveolar nerve, which is an alternative to the conventional extraction of third molars, which unlike the former technique, presents a high risk of injury to the inferior alveolar nerve. However, there is a need for new clinical studies, with a greater number of samples and with a longer follow-up period in order to detect potential adverse effects of the retained roots. Key words: Coronectomy, inferior alveolar nerve, nerve injury, wisdom tooth removal, paresthesia, and systematic review. PMID:25858081

PurposeVenous malformations (VM) involving the hand and forearm often lead to chronic pain and dysfunction, and the threshold for treatment is high due to the risk of nerve and skin damage, functional deterioration and compartment syndrome. The purpose of this study is to demonstrate that sclerotherapy of diffuse and infiltrative VM of the hand is a safe and effective therapy.Materials and MethodsA retrospective review of all patients with diffuse and infiltrative VM of the hand and forearm treated with sclerotherapy from 2001 to 2014 was conducted. All VM were diagnosed during the clinical visit by a combination of physical examination and imaging. Sclerotherapy was performed under imaging guidance using ethanol and/or sodium tetradecyl sulfate foam. Clinical notes were reviewed for signs of treatment response and complications, including skin blistering and nerve injury.ResultsSeventeen patients underwent a total of 40 sclerotherapy procedures. Patients were treated for pain (76 %), swelling (29 %) or paresthesias (6 %). Treatments utilized ethanol (70 %), sodium tetradecyl sulfate foam (22.5 %) or a combination of these (7.5 %). Twenty-four percent of patients had complete resolution of symptoms, 24 % had partial relief of symptoms without need for further intervention, and 35 % had some improvement after initial treatment but required additional treatments. Two skin complications were noted, both of which resolved. No motor or sensory loss was reported.ConclusionSclerotherapy is a safe and effective therapy for VM of the hand with over 83 % of patients experiencing relief.

Full Text Available Background: Transient neurological symptoms (TNS, was described in patients recovering from spinal anesthesia with lidocaine but its etiology remains unknown this study was evaluated the influence of ambulation time on the occurrence of TNSs after spinal anesthesia with lidocaine 5%. Materials and Methods: This randomized clinical trial was conducted on 60 patients with American Society of Anesthesiologists Grades I and II, who were candidates for lower abdominal surgery in supine or lithotomy positions. Patients were randomly divided into early ambulation group (Group A who were asked to start walking as soon as the anesthesia was diminished or to the late ambulation group (Group B who walked after at least 12 h bedridden. Participants were contacted 2 days after spinal anesthesia to assess any type of pain at surgical or anesthesia injection site, muscle weakness, fatigue, vertigo, nausea, vomiting, headache, and difficult urination or defecation. Results: Four subjects (13.3% in Group A and two patients (6.7% in Group B had pain at anesthesia injection site (P = 0.019. Fourteen patients in Group A (46.7% and six patients in Group B (20% had post-dural puncture headache (P = 0.014. Participants in Group B reported difficult urination more than Group A (P = 0.002. there were not statistically significant differences between two groups regarding frequency of fatigue, muscle weakness, vertigo, nausea, vomiting, difficult defecation, paresthesia, and the mean of visual analogue scale at the surgical site. Conclusion: Early ambulation after spinal anesthesia with lidocaine did not increase the risk of neurologic complication.

Smith, Adam M; Butler, Thomas H; Dolan, Michael S

2017-12-01

Elite-level women's fastpitch softball players place substantial biomechanical strains on the elbow that can result in medial elbow pain and ulnar neuropathic symptoms. There is scant literature reporting the expected outcomes of the treatment of these injuries. This study examined the results of treatment in a series of these patients. We identified 6 female softball pitchers (4 high school and 2 collegiate) with medial elbow pain and ulnar neuropathic symptoms. Trials of conservative care failed in all 6, and they underwent surgical treatment with subcutaneous ulnar nerve transposition. These patients were subsequently monitored postoperatively to determine outcome. All 6 female pitchers had early resolution of elbow pain and neuropathic symptoms after surgical treatment. Long-term follow-up demonstrated that 1 patient quit playing softball because of other injuries but no longer reported elbow pain or paresthesias. One player was able to return to pitching at the high school level but had recurrent forearm pain and neuritis 1 year later while playing a different sport and subsequently stopped playing competitive sports. Four patients continued to play at the collegiate level without further symptoms. Medial elbow pain in women's softball pitchers caused by ulnar neuropathy can be treated effectively with subcutaneous ulnar nerve transposition if nonsurgical options fail.

Full Text Available O osteossarcoma extra-esquelético é uma neoplasia rara caracterizada pela produção de osteóide "maligno". Esta condição tem sido descrita em faixa etária acima da esperada para o osteossarcoma ósseo, e a coxa é o local de predileção. Realizamos revisão da literatura e descrevemos o caso clínico de uma paciente de 19 anos de idade com história de massa na região cervical direita associada a parestesia dos membros superiores, a qual foi diagnosticada como portadora de osteossarcoma extra-esquelético. Enfatizamos as características clínicas, os aspectos das imagens em diversos métodos empregados (exames radiográficos convencionais, tomografia computadorizada, exame por ressonância magnética, análise histopatológica e os principais diagnósticos diferenciais desta afecção.Extraskeletal osteosarcoma is a rare neoplasm characterized by the formation of a malignant osteoid. This condition is usually described in patients aged greater than expected for other intraosseous osteosarcomas, and the thigh is the most common site. We report a clinical case of a 19-year-old female patient and review the literature. The patient presented with a mass in the right side of the neck and paresthesia of the upper limbs. The mass corresponded to an extraskeletal osteosarcoma. We discuss the clinical findings, image findings (conventional radiographs, computed tomography, magnetic resonance imaging, histopathology results and differential diagnosis of this condition.
