Belly Dancer Syndrome: An Unusual Cause of Abdominal Pain.

BACKGROUND: Belly dancer syndrome is a rare condition consisting of involuntary, repetitive, often rhythmic contractions of the diaphragm, causing undulating movements of the abdomen that recall those of a belly dancer. It is frequently associated with pain or discomfort in the upper abdomen or lower chest, but clinical symptoms are highly variable often resulting in late diagnosis. Very few pediatric cases have been reported, all of which were secondary to other conditions, and to our knowledge, no idiopathic cases of Belly Dancer Syndrome have been reported in children. CASE: We present the case of a 14-year-old girl who presented to the emergency department with sudden onset of abdominal pain. She was initially diagnosed and treated for pancreatitis because blood tests revealed very high lipase, but when jerky abdominal wall movements became pronounced, belly dancer syndrome was suspected. Full work-up included abdominal ultrasound, chest x-ray, electroencephalogram, electromyography, magnetic resonance imaging, and toxic screen, all of which were normal. She was treated successfully with oral diazepam and referred to a pediatric neuropsychiatrist. CONCLUSIONS: Belly dancer syndrome is a rare condition often misdiagnosed owing to multiple presentations. Increased awareness is necessary to prevent late diagnosis and incorrect treatment.

Concomitant Parenchymal, Subarachnoid, and Ventricular Neurocysticercosis in Rome, Italy: A Case Report with a 4-Year Follow-Up.

Neurocysticercosis (NCC) is caused by the larval stage of Taenia solium. This parasitic disease is endemic in many areas of the world and is emerging in Europe. NCC can affect different brain regions, but simultaneous involvement of the parenchymal, subarachnoid, and ventricular regions is rare. We report the case of a 39-year-old woman from Honduras, resident in Rome for 10 years, who presented to the Emergency Department complaining of headaches, transient hemianopsia, and bilateral papilledema. MRI showed a concomitant parenchymal, subarachnoid, and ventricular involvement in the brain. T. solium IgG antibodies were detected in the blood. The etiological diagnosis of NCC was obtained by identifying T. solium in cerebrospinal fluid using Next Generation Sequencing. Endoscopic neurosurgery with the placement of a ventricular shunt and medical long-term anti-parasitic treatment with a cumulative number of 463 days of albendazole and 80 days of praziquantel were performed. A successful 4-year follow-up is reported. NCC is one of the most common parasitic infections of the human CNS, but it is still a neglected tropical disease and is considered to be an emerging disease in Europe. Its diagnosis and clinical management remain a challenge, especially for European clinicians.

Brain excitability changes in the relapsing and remitting phases of multiple sclerosis: a study with transcranial magnetic stimulation.

OBJECTIVE: Recent functional and imaging studies have substantially contributed to extend the concept of multiple sclerosis (MS), classically regarded as a disease limited to the myelin axonal sheath. Several findings, in fact, point to a parallel involvement of neuronal components of the central nervous system (CNS) in the course of MS. In the present study, therefore, we explored, in MS patients, some characteristics of central motor pathways related to changes of neuronal excitability as measured using transcranial magnetic stimulation (TMS). METHODS: Seventy-nine patients affected by relapsing-remitting (RR) MS were examined using single and paired TMS in order to assess excitability changes in the hand motor cortex occurring during relapse and/or remission of the disease. The analyzed parameters were: motor-evoked potential (MEP) threshold, silent period (SP), intracortical inhibition (ICI) with paired pulses from 1 to 6 ms interstimulus intervals (ISIs), and central motor conduction time (CMCT). RESULTS: The analysis of variance exhibited a strong correlation (P<0.001) between the clinical phase and the type of excitability changes: 'relapsing' patients showed increased threshold and reduced SP duration. 'Relapsing' patients also displayed a significant lack of normal intracortical inhibition (ICI). By contrast, 'remitting' patients showed a significant SP prolongation with normal motor thresholds. CONCLUSIONS: The present findings reveal changes in cortical excitability that might play a role in the pathophysiology of MS symptoms. In particular, the relapsing phase of MS has been found to be associated with cortical hyperexcitability irrespective of the site of clinical manifestation or new plaque formation. These results might help to explain the puzzling picture of neurological symptoms observed in MS patients during different phases of the disease. SIGNIFICANCE: Alterations of neuronal components of the CNS play a role in MS.

Fracture-dislocation of the shoulder and brachial plexus palsy: a terrible association.

Primary post-traumatic anterior dislocation of the shoulder with associated fracture of the greater tuberosity and brachial plexus injury is rare and, to our knowledge, has never previously been reported in the literature. We present a case of this unhappy triad in which a brachial plexus injury was diagnosed and treated 3 weeks later. The characteristics of this rare condition are discussed on the basis of our case and the published literature in order to improve early diagnosis and treatment of this lesion.
