Surgical management of overfilling of the root canal: a case report.

Overfilling of the root canal is one of the most common errors encountered in dental practice. A 40-year-old woman complained of paresthesia and swelling affecting the left side of the mandible. Panoramic radiographs revealed that the root canal was overfilled; endodontic restorative material extended as far as the mandibular angle. Several months after surgical removal of the tooth and excess filling material, the symptoms subsided.

[Aquadynia: a role for VIP?].

BACKGROUND: Aquadynia (water-related cutaneous pain) is a very rare disorder, recently described. CASE REPORT: A 40 year-old woman suffered from aquagenic pruritus, complicated by paresthesia and pain. There was no clinical argument in favor of a psychiatric disorder, Fabry's disease or any other disease. Clinical and histological cutaneous examinations were normal. Immunohistochemical study of neurotransmitters (substance P, calcitonin gene-related peptide or CGRP, vasoactive intestinal peptide or VIP, somatostatine) did not show any modification in nerve density. However, VIP-immunoreactive epidermal cells were observed. Electromyography and study of somesthesic-evoked potentials were normal. No treatment had provided any efficacy. Clonidine and capsaicin had been prescribed with partial success. DISCUSSION: Three other cases of aquadynia have been reported. Differential diagnoses of aquadynia are aquagenic pruritus and urticaria, hysteria or simulation, Fabry's disease, erythermalgia, peripheral neuropathy or polycythemia vera. The presence of VIP-immunoreactive cells suggests that VIP could be produced by these cells after contact with water. The effects of propanolol and clonidine on aquadynia are in favor of an adrenal component.

[Subacute myelitis revealed by human immunodeficiency virus infection].

A 35 year-old heterosexual man had a six months history of cervical myelitis with progressive paraplegia, leg weakness and paresthesia of the four extremities. Spinal cord MRI showed a high T2 signal intramedullary lesion wide from the bulbo-medullary junction to D4. Post gadolinium T1 sequence revealed an enhancement in front of C3-C4 vertebrae. VIH serology was positive. Corticosteroid treatment achieved a marked improvement. In addition to vacuolar myelopathy, well-known at the advanced stages of the HIV infection (AIDS), myelitis and clinical pictures simulating multiple sclerosis were described during early stages of the infection. These inflammatory lesions of the central nervous system and sometimes of the peripheral nervous system seems to be related to the immune response dysfunction induced by the VIH.

[Cheiro-oral syndrome due to a cortical infarction in the precentral gyrus: a case report].

We report a 65-year-old woman with sudden onset of paresthesia on the left side of the lip and left thumb. Neurological examinations did not demonstrate any disturbance of higher brain function or motor function except for subjective thermohyperesthesia of the left thumb. Brain MRI demonstrated a small high intensity lesion on T2-weighted images (T2 WI) and diffusion-weighted images (DWI) in the right anterior precentral gyrus. She was diagnosed with cerebral infarction presenting with pure cheiro-oral syndrome (COS). Her neurological symptoms were completely abolished 4 or 5 days later. The thalamus is the region responsible for COS in the majority of cases while reports that a cortical infarction causes COS are rare, because it is difficult to show a small cortical lesion on CT or conventional T2WI. DWI is superior to T2 WI in discriminating between acute and chronic ischemic lesions as well as in detecting small cortical lesions adjacent to the cerebrospinal fluid. In this patient, the lesion was vaguely hyperintense on T2 WI and difficult to differentiate from an artifact caused by cerebrospinal fluid. The precentral gyrus infarction detected on DWI was thought to cause COS in this patient. Not only lesions of the postcentral gyrus as a primary sensory cortex but also those of the precentral gyrus or opercula causing COS were described in previous reports, indicating that the hand and mouth sensory areas may be widely distributed. Cortical mapping studied by electrical stimulation through subdural grid electrodes also supports this finding. Further examination of the relation between neurological symptoms and localization on MR images such as DWI is needed to clarify the distribution of the sensory cortex.

Cutaneous lesion associated with multiple endocrine neoplasia type 2A: lichen amyloidosis or notalgia paresthetica?

Three patients of a French family demonstrated an association of multiple endocrine neoplasia type 2A (MEN 2A) with a pruritic scapular skin lesion. The lesions are similar to those described as familial cutaneous lichen amyloidosis in unrelated MEN 2A and medullary thyroid carcinoma families, but histological, immunohistochemical, and ultrastructural analysis of skin biopsies from each patient in the French family did not show amyloid deposition. The topography of the lesion follows dermatomes C8-D3. The patients report not only pruritus but also paresthesia and hyperalgesia, and one showed touch hypoesthesia and pain hyperesthesia in the area of the lesion. Such an association of cutaneous and neurological features suggests notalgia paresthetica (NP), a neuropathy of the posterior dorsal rami nerves. We thus suggest that the cutaneous lesions associated with MEN 2A might be secondary to pathology in the neural crest-derived dorsal sensory nerves. The amyloid, when present, would be secondary to scratching. We propose that patients presenting with familial NP be suspect for MEN 2A.

[Damage to the lateral cutaneous femoral nerve after transfemoral angiography].

We report on two patients with lesions of the lateral cutaneous nerve of the thigh after transfemoral angiography. Symptoms were hypesthesia, dysesthesia and hypalgesia of the right lateral thigh. One patient had no hematoma, the other a hematoma of the medial thigh which did not enlarge thigh circumference. Both patients had had a tight pressure bandage applied for 24 hours. There were no signs of a femoral nerve lesion. Both patients were severely distressed by paresthesia. The numbness subsided after three weeks in one patient, but pain persisted. The other patient had symptoms for over six months. The lateral cutaneous nerve of the thigh is located distinctly lateral to the puncture site in transfemoral angiography. Hence we suggest that the nerve lesion was caused neither by the puncture itself nor by a hemorrhage, but by the tight bandage.

[Transcutaneous oximetry in symptomatic diabetics].

In a group of 33 patients affected by diabetes mellitus transcutaneous oxygen tension (PtcO2) was measured by means of a Clark polarographic electrode. Patients were divided into 3 groups according to the symptoms and/or to the clinical findings: group A: paresthesia (22 limbs); group B: claudication (6 limbs); group C: rest pain and/or necrosis (13 limbs). Moreover, group C was divided into: C1 trophic neuropathy lesion (7 limbs) and C2 trophic ischemic lesion (6 limbs). Our data point out that there is a statistically significant difference between mean PtcO2 values in limbs with trophic ischemic lesions versus the other 3 groups. Therefore, PtcO2 is particularly indicated and useful in the study of diabetic patients with peripheral vascular disease where integrates the other instrumental noninvasive techniques.

[Ataxic Guillain-Barré syndrome with delayed facial diplegia].

We described a patient with ataxic Guillain-Barré syndrome who subsequently developed facial diplegia. A 38-year-old man developed ataxia, distal limb paresthesias, mild dysphagia, urinary retention and orthostatic hypotension a week after an episode of laryngitis. He had high titers of serum anti-GQ1b, anti-GD1b, anti-GM1b, anti-GT1a, and anti-GD1a IgG antibodies during the acute phase. Although the initial symptoms markedly improved by intravenous immunoglobulin therapy, asymmetric facial diplegia subsequently occurred and remained longer than ataxia. Similar course of facial nerve palsy has been reported in patients with Fisher syndrome. Common pathophysiological mechanism may function in the development of delayed facial diplegia in Fisher syndrome and ataxic Guillain-Barre syndrome.

[Carpal tunnel syndrome].

The name of Carpal Tunnel Syndrome (CTS) refers to a complex of symptoms resulting from the pressure exerted on the median nerve in the carpal tunnel area [81]. In most cases, it is not possible to establish CTS causes, and we diagnose idiopathic CTS. CTS is the most frequent pressure neuropathy. Typical clinical symptoms include sensory effects in the forms of pain paresthesia or hypesthesia, limited to the wrist area innervated by the median nerve, presence if Tinel's symptoms, or a positive Phalen's test. In more advance cases, doctors find motor symptoms displayed by difficulties in the performance of precise activities, grasp weakness or thenar muscle atrophy. In some patients, we observe autonomous symptoms, e.g. skin perspiration disorders (dry skin on thumb, index and middle fingers), or vasomotor disorders. The most essential for diagnosis confirmation are electrophysiological examinations, which evaluate the median nerve functions. Sometimes, imaging techniques are useful, e.g. ultrasound, MRI and CTS scanning of the wrist. The most effective form of idiopathic treatment of CTS is surgery.

Compression of the radial branch of the median nerve due to an anomalous muscle belly of the first lumbrical in a child.

Compression of the radial branch of the median nerve due to an anomalous muscle belly of the first lumbrical is a new diagnostic entity. We found this in the case of a 12-year-old girl with intermittent pain, weakness and paresthesias in the right hand. Provocative signs and symptoms in the distribution of only the radial branch of the median nerve are the most important signs distinguishing this case from carpal tunnel syndrome.

Calciphylaxis in a patient with POEMS syndrome without renal failure and/or hyperparathyroidism. A case report.

POEMS (Crow-Fukase) syndrome is a rare plasma cell lymphoproliferative disorder associated with polyneuropathy (P), organomegaly (O), endocrinopathy (E), monoclonal (M) gammopathy and skin (S) abnormalities. The latter are usually not specific and include hyperpigmentation, hypertrichosis, cutaneous angioma and skin-thickening. A 45-year-old Italian woman was admitted to hospital because of muscle weakness, marked fatigue and paresthesia of the upper and lower extremities. Two and a half years earlier, a POEMS syndrome had been diagnosed on the basis of a history of organomegaly and mild lymphadenopathy, IgA-lambda monoclonal gammopathy, hypothyroidism, severe lower and upper limb sensory-motor peripheral neuropathy and a single osteosclerotic lesion in the left humerus. Eight weeks later, she developed skin lesions bioptically shown to be due to calciphylaxis-induced cutaneous vasculitis. To our knowledge, this is the first case of POEMS syndrome with this peculiar type of vasculitis. The absence of predisposing conditions, namely renal failure, hyperparathyroidism or clotting disorders renders the pathogenetic mechanism(s) of this severe type of vasculitis more intriguing.

Masked deficit of vitamin B12 in the patient with heterozygous beta-thalassemia and spastic paraparesis.

The spinal cord, brain, optic nerves and peripheral nerves may be affected by vitamin B12 (cobalamin) deficiency. Deficiency of vitamin B12 also causes megaloblastic anaemia, meaning that the red blood cells are usually larger than normal. In this paper we report a 16-year old girl who was referred to us for the evaluation of mild paraparesis and paresthesias marked by tingling "pins and needles" feelings and general weakness. The patient, her parents and sisters were on a strict vegan diet, which made us believe that vitamin B12 deficiency may be the possible cause of the neurologic clinical manifestations. The serum level of vitamin B12 was low, but there was no macrocytosis in the routine blood examination. The electrophoresis of haemoglobin was pathologic, there was 3.7% of HbA2 and 11.6% of HbF (heterozygous form of beta-thalassaemia). When megaloblastic anaemia occurs in combination with a condition that gives rise to microcytic anaemia, many megaloblastic features may be masked. Instead of being macrocytic, the anaemia could be normocytic or even microcytic. Vitamin B12 deficiency is a diagnosis that must not be overlooked. This case report turns the light on the fact that increased MCV is a hallmark in vitamin B12 deficiency, but it is not an obligatory sign.

U.S. navy diver/aviator/skydiver with AGE from a previously unknown PFO.

A 32 year old US Naval aerospace physiologist with dive, jump and flight qualifications presented to a US Navy hyperbaric medicine department complaining of nausea, unsteadiness and left hand and forearm paresthesia that began almost immediately after completing a 28ft/ 40min recreational dive. Following an abbreviated history and physical examination the patient was diagnosed to be suffering from an arterial gas embolism. He was treated with hyperbaric therapy during which his symptoms resolved. Follow-on transesophageal echocardiography revealed an atrial septal aneurysm with a patent foramen ovale resulting in a right-to-left shunt after Valsalva maneuver, but no evidence of ventricular dysfunction, wall motion abnormalities, or abnormal ejection. His episode was attributed to paradoxical air embolism and he was disqualified from further special duty. In order to regain his dive, jump and flight qualifications, the patient elected to undergo repair of the cardiac defect with a device that is relatively new in the operational military setting. The procedure was a success, he was granted waivers for his prior qualifications, and remains in that status to this day. This is the first known case where an atrial septal occluder has been used to preserve these special duty qualifications.

[Transient neurological syndrome after spinal hyperbaric bupivacaine: a new case].

A 47-year-old woman underwent hysteroscopy and removal of an endometrial polyp because of irregular, acyclic bleeding of 6 months' duration. The procedure was carried out under spinal anesthesia. No adverse events occurred during puncture or surgery, or in the immediate postoperative recovery period. Recovery from the sensory and motor block was normal. Twenty-four hours after surgery gluteal and lower limb pain and paresthesia developed, with no sensory or motor deficit. The symptoms suggested transient neurological syndrome. This syndrome has been defined by pain in the lower limbs, buttocks, thighs and calves after uncomplicated spinal anesthesia and full recovery from the sensorimotor block during the immediate postoperative period (first 24 hours). The condition is self-limiting and does not leave permanent neurological sequelae. Recent studies have demonstrated biochemical and anatomical changes that provide a structural basis for this clinical entity. According to this literature, transient neurological syndrome might be a mild expression of local anesthetic toxicity. Recent findings show that the initial injury to the nerve cell membrane, induced by high concentrations of local anesthetic could lead to permanent neuronal damage.

[Multiple mononeuropathy associated to treatment with pravastatin].

INTRODUCTION: The first reports of neuropathy due to treatment with statins appeared in 1994, although it is an infrequent complication. It usually consists of an axonal polyneuropathy, which is predominantly sensory, distal and symmetric, and may be subacute or chronic. We present here the second case reported in the literature of multiple mononeuropathy associated to the use of statins. CASE REPORT: A 51-year-old female patient who, after beginning therapy with pravastatin, presented with progressive, asymmetrically distributed, distal paresthesias in the limbs and an unstable gait. An electromyographic study was compatible with multiple mononeuritis. Results of complementary tests that were carried out to preclude other causes of multiple mononeuropathy were normal. The patient's condition improved on withdrawing treatment with the drug and it became worse again when therapy was restarted. When pravastatin therapy was stopped for good, the patient's condition progressively improved until she was practically free of symptoms. CONCLUSIONS: The relationship between treatment with statins and the appearance of polyneuropathy has been proved in different epidemiological case-control studies. It does not only appear as the classical distal symmetrical polyneuropathy, but has also been reported as taking on atypical clinical forms including a few cases, like ours, of multiple mononeuropathy. The risk of developing this complication is low and is offset by the cardiovascular benefits offered by statins, although it may become more common in the future due to the increasing rate of use of these agents. It is important to bear this cause of neuropathy in mind, given the fact that it is potentially reversible.

Neurosarcoidosis presenting as acute infarction on diffusion-weighted MR imaging: summary of radiologic findings.

A 36-year-old woman presented with acute-onset right lower extremity paresthesias, dysarthria, right facial droop, and right hemiparesis. CT and MR imaging of the brain revealed extensive white matter disease and left basal ganglia infarction with dural and leptomeningeal enhancement. Differential considerations included vasculitis, granulomatous disease, and neoplasm. Chest, abdomen, and pelvis CTs were normal. Right temporal lobe biopsy revealed noncaseating granulomatous inflammation consistent with neurosarcoidosis.

[Aneurysmal bone cyst of the spine. Case report].

The aneurysmal bone cyst (ABC) is a fast-growing tumor of undefined neoplastic nature. It is occasionally an aggressive benign lesion whose treatment of choice is a complete resection, even though the risk of profuse transoperative bleeding exists. We present a female patient with thoracic spine deformity, with progressive paresthesias and muscle weakness of lower extremities that evolved to paralysis of both lower extremities and sphincter incontinence. Based on radiographic films, lytic lesions were identified at T7 to T9 vertebrae as well as medullary space invasion. In electrophysiologic tests, a complete somatosensorial pathway block was reported. Prior to resection of the neoplastic lesion and thoracolumbar stabilization, an incisional biopsy was performed. There was no postoperative medullary functional improvement. Morphological findings corresponded to an aneurysmal bone cyst at T8. This lesion is mainly located in the long bones and less frequently of the spine, where instability and medullary compression may occur. It is possible to confuse this neoplasia with other lesions. Hence, definite diagnosis with biopsy is necessary for determining an adequate therapeutic plan to eradicate recurrence risk or associated neurologic sequelae, as well as to gain proper stability at the involved vertebral segments.

Steroid myopathy: clinical and immunohistochemical study of a case.

A 42 year old woman with foot process disease, was treated with corticosteroids for 6 years. She had been suffering, for about 3 years from progressive muscle weakness of the limbs, accompanied by general paresthesia, cramps of the calves and burning muscle pain both at rest and an effort. The clinical, neurophysiological and histochemical examination indicated noninflammatory myopathic damage. The progressive reduction of corticosteroid dosage led rapidly to a distinct improvement, but not to a remission, of symptoms. Clinical and laboratory findings were consistent with those observed in most cases of steroid myopathy described in literature. We discuss the possible pathogenetic role of corticosteroids in this affection.
