The number of patients submitted to bariatric surgery to treat morbid obesity is increasing, therefore, some nutritional deficiencies, with which many physicians are no longer familiarized, are reappearing. Postoperatively, many nutritional disorders may occur, one of them is thiamine deficiency (beriberi). The thiamine and/or vitamin B12 deficiency can correspond to 40% of the neuropathy cases after bariatric surgery. Two patients with the clinic of peripheral neuropathy and Wernicke-Korsakoff syndrome will be reported. Some months after the surgery, they presented prostration, depression, mental confusion and nystagmus, associated with pain and paresthesia in limbs (especially lower limbs). With the diagnostic hypothesis of beriberi, the treatment with thiamine started. One of the patients presented complete improvement of the neurological symptoms, however the other one remained with motor deficiency, exactly the one who spent a longer period of time between the symptoms appearance and the treatment beginning. These cases serve to alert us about the importance of nutritional vigilance after bariatric surgery.

Burning mouth syndrome is characterized by both positive (burning pain, dysgeusia and dysesthesia) and negative (loss of taste and paraesthesia) sensory symptoms involving the lips and tongue, mainly the tip and anterior two-thirds. BMS patients report a persistently altered (metallic) taste or diminished taste sensations. Acidic foods such as tomatoes and orange juice cause considerable distress. Most of the common laboratory tests suggested for BMS patients will be negative as well. BMS is best subcategorized as primary BMS, no other evident disease, and secondary BMS, which is defined as oral burning from other clinical abnormalities. The presence of BMS is very uncommon before the age of 30; 40 years for men. The onset in women usually occurs within three to 12 years after menopause, and is higher in women who have more systemic disease. Quantitative assessment of the sensory and chemosensory functions in BMS patients reveals that the sensory thresholds (significantly higher) are different than in controls. Tongue biopsies have shown that there is a significantly lower density of epithelial nerve fibers for BMS patients than controls. The above data generally support the idea that BMS is a disorder of altered sensory processing which occur following the small fiber neuropathic changes in the tongue. BMS patients frequently have depression, anxiety, sometimes diabetes, and even nutritional/mineral deficiencies, but overall these co-morbid diseases do not fully explain BMS. The management of BMS is still not satisfactory, but because BMS is now largely considered to be neuropathic in origin, treatment is primarily via medications that may suppress neurologic transduction, transmission, and even pain signal facilitation more centrally. Finally, spontaneous remission of pain in BMS subjects has not been definitely demonstrated. The current treatments are palliative only, and while they may not be much better than a credible placebo treatment, few studies report relief without intervention.

Patients with widespread pain or fibromyalgia syndrome have many symptoms besides musculoskeletal pain: e.g. fatigue, sleep difficulties, a swollen feeling in tissues, paresthesia, cognitive dysfunction, dizziness, and symptoms of overlapping conditions such as irritable bowel syndrome, headaches and restless legs syndrome. There is evidence for central sensitization in these conditions, but further studies are needed. Anxiety, stress and depression are also present in 30-45% of patients. Other factors that may contribute to symptoms include endocrine dysfunction, psychosocial distress, trauma, and disrupted sleep. Evaluation of a patient presenting with widespread pain includes history and physical examination to diagnose both fibromyalgia and associated or concomitant conditions. Fibromyalgia should be diagnosed by its own characteristic features. Some patients with otherwise typical symptoms of fibromyalgia may have as few as four to six tender points in clinical practice. Patients with rheumatoid arthritis and systemic lupus erythematosus should be evaluated for fibromyalgia, since 20-30% of them have associated fibromyalgia, requiring a different treatment approach.

Restless legs syndrome (RLS) is a sensorimotor disorder characterized by distressing sensations deep inside the limbs, typically occurring at bedtime or rest. These paresthesias involve an irresistible urge to move the limb, which provides temporary relief but at the expense of sleep and quality of life. The pathophysiology of RLS has been related to dopaminergic pathway dysfunction, thereby aligning it closely with depression from both pathophysiologic and treatment perspectives. Certain antidepressant drugs, including the selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), may induce or exacerbate RLS. We describe the case of a 34-year-old woman with no history of RLS who came to the emergency department with acute decompensated heart failure. After 7 days of hospitalization, she was waitlisted to receive a heart transplant. Her mood became depressed, and she requested a psychiatric consultation; escitalopram 10 mg at bedtime was started. Within 2 days of starting therapy, she developed very severe (determined by a score based on an RLS symptom rating scale) RLS symptoms, warranting the discontinuation of escitalopram. Within 2 days of stopping therapy, her RLS symptoms improved considerably (rated as mild). One week later, the patient was rechallenged with a lower dose of escitalopram, and her very severe RLS symptoms reappeared. Within 2 days of stopping escitalopram, her RLS symptoms again improved, with complete resolution 1 week later. Using the Naranjo adverse drug reaction probability scale, which assesses the probability of a drug causing an adverse event, the patient's score was 9, indicating a definite adverse drug reaction. Although published case reports have linked fluoxetine, sertraline, citalopram, paroxetine, and mirtazapine to RLS, this is the first report, to our knowledge, of escitalopram as a cause of RLS. Based on this case and additional data published with other SSRIs and SNRIs, we believe that escitalopram should be added to the list of agents that can induce RLS.

Clinical and experimental evidence support a relationship between susceptibility to chronic pain and a subjacent depression. Nevertheless, it's not clear if the currently available clinical evaluation instruments for depression allow for linking both disorders. Thus, we evaluated a Zung's autoscale for depression and its different categories: affective, physiological, motor and psychological, as possible predictors of sensorial and autonomic alterations and vulnerability to clinical chronic pain. In 32 healthy controls and 11 subjects with minor depression and free of treatment, ischemic pain was first induced by applying a tourniquet on the dominant arm, and then followed by paresthesias during the reperfusion of arm as the tourniquet is released. Ischemic muscular pain, post-ischemic paresthesias and associated cardiovascular responses were recorded throughout the experimental procedure. The affective category's score was correlated linearly in individual form with the greatest number of variables and it was adjusted to a model of multiple regressions that almost explained the variance in 100% with a contribution of the sensorial and autonomic variables of a 70% and 30%, respectively. In addition, the affective category was 50% greater in subjects with persistent clinical pain. The Zung's index and the other categories had a smaller number of individual linear correlations and models of multiple correlations that only explained between 30-70% of the variance, with a more predominant contribution of the autonomic variables (20-50%), especially in the psychological category. This suggests that the affective category predicts cutaneous-muscular sensorial alterations with greater effectiveness than the Zung's total index.

The study was designed to investigate effect of alpha-lipoic acid (alphaLA) and mexidol on clinical manifestations of diabetic neuropathy (DN) and the associated changes of the affective status in patients with diabetes mellitus at early stages of diabetic foot syndrome (DFS). Integral indicator of clinical symptoms of distal symmetric sensorimotor polyneuropathy (according to the neuropathic signs and symptoms scale) significantly decreased within 14 days after the onset of the treatment with alphaLA (600 mg/day) and mexidol (300 mg/day). Antineuropathic effect of alphaLA was associated with a rise in the left ventricular ejection fraction. Mexidol reduced the severity of DN-related depression and was more efficacious than alphaLA in terms of beneficial effect on spasms and paresthesia (pricking and burning sensation, numbness) in distal segments of the lower extremities. The above clinical effects of alphaLA and mexidol were unrelated to changes of glycemia, lipidemia amd lipid peroxidation.

The objective of the study was to determine the frequency of smoking in fibromyalgia (FM) and rheumatoid arthritis (RA) patients and investigate its association with the symptoms of FM. We included age-matched 302 FM (289 F, 13 M), and 115 (105 F, 10 M) RA patients. All patients were questioned about smoking and the severity of their chronic widespread pain (CWP) and symptoms of FM by using a visual analog scale (VAS, 0-10) and FM impact questionnaire. In addition, patients were asked questions about depression and anxiety. The frequency of smoking in FM patients (77 subjects, 25.5%) tended to be higher than in RA patients (19 subjects, 16.5%) (P = 0.05). When the features of smoker FM patients were compared to others, it was observed that the frequencies of subjects with an education duration >9 years (P < 0.001) and subjects with an history of psychiatric therapy (P = 0.01) and alcohol consumption (P = 0.013) were higher. The mean age of FM patients with smoking (P = 0.002) was lower; the duration of FM (P = 0.024) was shorter; and the scores of CWP severity (P = 0.05), unrestorative sleepiness (P = 0.017), paresthesia (P = 0.038) and anxiety-depression (P = 0.007) were higher. An important proportion of FM patients, nearly one-fourth, were re-smokers. Smoker FM patients had higher education level, and the severity of their FM-related symptoms like CWP and their anxiety-depression scores were higher.

Few studies have evaluated age and racial/ethnic differences in the prevalence of symptoms in human immunodeficiency virus (HIV)-infected persons. Thus, the objective of this study was to compare the prevalence of gastrointestinal, metabolic, general malaise, neurologic, or other self-reported symptoms by age and race/ethnicity among 1574 HIV-infected women enrolled in the Women's Interagency HIV Study and 955 HIV-infected men who have sex with men (MSM) enrolled in the Multicenter AIDS Cohort Study. All patients had known dates of initiation of highly active antiretroviral therapy. It was observed that women aged 50 years or more were less likely to experience gastrointestinal symptoms (24% vs. 27%; multivariable P=0.024), but more likely to experience general malaise (47% vs. 37%; multivariable P=0.004), neurologic (44% vs. 38%; multivariable P=0.048), or other symptoms (40% vs. 28%; multivariable P<0.001) compared with women less than 40 years of age. Only neurologic symptoms had a higher prevalence among older MSM (52% vs. 37%; multivariable P=0.002), largely driven by paresthesias (48% vs. 31%; multivariable P=0.004), the most common individual symptom reported by men. Caucasian women generally had the highest prevalence of symptoms, and African American women had the lowest prevalence. Few racial/ethnic differences were noted for MSM. Depression and a prior diagnosis of acquired immunodeficiency syndrome were the strongest and most consistent predictors of clinical symptoms in both cohorts. In summary, the prevalence of reported symptoms varies with patient race/ethnicity, age, and modifiable factors, such as depression and HIV disease stage. Clinicians should consider these factors when counseling patients regarding potential adverse effects of antiretrovirals or symptoms associated with HIV disease.

Hemifacial spasm (HFS) is a chronic movement disorder which presents as clonic and/or tonic facial muscle contractions frequently accompanied by many other sensory (visual or auditory disturbances, pain), motor (facial weakness, trismus, bruxism, dysarthria) and/or autonomic (lacrimation, salivation) symptoms. The aim of the study was to assess the occurrence of HFS non-motor and motor-related symptoms and their responsiveness to botulinum toxin type A (BTX-A) therapy. 56 HFS patients were included in the open-label design study. Patients were examined three times: before BTX-A injection, and 2 and 12 weeks later. The occurrence of non-motor and motor-related symptoms was assessed by a special questionnaire, and the severity of HFS was rated by the Clinical Global Impression-Severity scale (CGI-S) and depression symptoms by the Beck Depression Inventory (BDI). Over 81% of the patients before BTX-A therapy reported HFS non-motor and motor-related symptoms. Almost 50% of the patients reported more than three symptoms. The most frequent symptoms were: tearing (44.5%), eye irritation (39.3%), facial paraesthesia (26.8%) and hearing of a "clicking" sound (25.0%). 2 weeks after BTX-A injection 75% of the patients did not report any symptoms and 20% reported only one or two. 3 months later the number of symptoms had increased again, with 57% of patients reporting at least one. The number of HFS non-motor and other symptoms did not correlate with the patients' age, disease duration and the presence of neuro-vascular conflict, but were positively correlated with the CGI-S and BDI scores. This study showed that muscle contractions in HFS patients are commonly accompanied by non-motor and other motor-related symptoms and most of them are reduced following BTX-A treatment.

Sensory neuropathy (HIV-SN) is a common cause of pain in HIV-infected people. Establishing a diagnosis of HIV-SN is important, especially when contemplating opioid use in high-risk populations. However physical findings of HIV-SN may be subtle, and sensitive diagnostic tools require specialized expertise. We investigated the association between self-report of distal neuropathic pain and/or paresthesias (DNPP) and objective signs of HIV-SN. Data were obtained from the Central Nervous System HIV Antiretroviral Therapy Effects Research (CHARTER) study. Out of 237 participants, 101 (43%) reported DNPP. Signs of HIV-SN were measured by a modified Total Neuropathy Score (TNS), composed of six objective sensory subscores (pin sensibility, vibration sensibility, deep tendon reflexes, quantitative sensory testing for cooling and vibration, and sural sensory amplitude). Self-report of DNPP was associated with all six TNS items in univariate analysis and with four TNS items in multivariate analysis. The sensitivity and specificity of self-report of DNPP in detecting the presence of a sensory abnormality were 52% and 92%, respectively with a PPV of 96% and a NPV of 34%. Increasing intensity of pain measured on a visual analog scale was associated with increasing severity of sensory abnormality. In summary, our results suggest that HIV-infected patients reporting symptoms consistent with HIV-SN, such as tingling, pins and needles, or aching or stabbing pain in the distal lower extremities, usually have objective evidence of HIV-SN on neurologic examination or with neurophysiologic testing. This finding holds true regardless of demographic factors, depression or substance use history.
