Chloroquine is considered essentially nontoxic when used for the chemosuppression of malaria, but gastrointestinal upsets, headache, blurring of vision, pruritus, and uritcaria may occur during chloroquine therapy. Recently, Bhargava et al. and Eronini and Eronini have reported the extrapyramidal syndrome (EPS) following chloroquine therapy in adults. The clinical manifestations included upward rolling of the eyeballs, retraction of neck and back, trismus with marked difficulty in speech, and coarse tremors. Observations of 4 instances of EPS in children following chloroquine therapy for malaria are reported. A 2-1/2 year old girl was admitted to the All India Institute of Medical Sciences Hospital with a 4 day history of intermittent high grade pyrexia with chills and rigors. Following treatment with oral chloroquine in the recommended therapeutic dosage, the fever responded, but the child became drowsy and developed paroxysms of involuntary movements of the tongue, torticollis, torsion dystonia of the limbs, and parosysms of tonic muscular spasms. She completely recovered spontaneously within 48 hours. The 2nd case was that of a 12-year old female brought to the hospital with a 15-day history of intermittent high grade fever with chills and rigors. The patient was started on chloroquine sulfate in the recommended therapeutic dose. After an interval of 4 days she developed coarse tremors of the hands, upward rolling of the eyeballs, episodic deviation of the angle of the mouth towards the left, and trismus. These symptoms disappeared spontaneously within 8 hours. A 6-year old girl, the 3rd case, developed episodes of opisthotonous, upward rolling of the eyeballs, protrusions of the tongue, intermittent writhing movements of the upper limbs, and drowsiness following the ingestion of 6 tablets of chloroquine sulfate for suspected diagnosis of malaria. She spontaneously recovered from EPS over a period of about 48 hours. The 4th case, a 7-year old boy, gave a history of high grade fever with chills and rigors of 1 day's duration. He developed drowsiness, tonic spasms of the neck, upward rolling of the eyeballs, and writhing contortions of all limbs about 2 hours following intravenous administration of 100 mg of chloroquine. 8 hours later an additional 100 mg chloroquine was given intravenously for the mistaken diagnosis of cerebral malaria. On examination the child was drowsy, had generalized stiffness, torticollis, and trismus. He recovered gradually over a 48-hour period without any specific therapy. The exact mechanism of production of EPS remains uncertain.

A case of tetanus occurring after induced abortion is reported. The patient gave a history of low grade fever with chill and rigors, headache, neck pain and Trismus. She subsequently developed respiratory distress. However, incorrect information from the patient resulted in the delay to locate and eradicate the source of infection. Early referral to an intensive care unit for ventilatory assistance was the most appropriate step to save the patient. Complications which occurred during the course of the disease were sometimes difficult to overcome. These complications were probably related to the duration of stay in the intensive care unit. Their incidence could be reduced by more meticulous patient care.

Ninety-one new patients with myofascial pain-dysfunction (MPD) syndrome were studied prospectively. The patients experienced aural fullness, tinnitus, vertigo, odynophagia, and headache in addition to the cardinal symptoms of otalgia, muscle tenderness, temporomandibular joint (TMJ) click, and trismus. Some nonmasticatory muscles were found to be tender as frequently as the masticatory muscles. It is proposed that MPD syndrome as seen clinically involves more than just the masticatory musculature and is a composite of several head and neck myofascial pain syndromes including tensor tympani syndrome, muscle tension headache, cervical syndrome, and hyoid syndrome.

Lidocaine is the first local anesthetic of the amide type to be introduced to clinical practice. It is a versatile drug and in anesthesia, is the most commonly used local anesthetic because of its aptness of potency, rapid onset, moderate duration of action and topical activity. It is relatively safe and useful in many other clinical settings. Unfortunately, systemic intoxication and psychotic reaction associated with its use often occur because of its popularity and wider safety margin, for which guide in use is often ignored and overdose becomes commonplace. Moreover, due to its universality in use seldom reports have recently dealt with lidocaine, particularly regarding its toxic reaction. Here, we present a case of lidocaine intoxication occurring during circumcision for a reviewal of the problem. A healthy young male, weighing 65 kg, underwent circumcision for phimosis under penile block with 2% lidocaine which totaled 600 mg. Twenty minutes after injection the patient developed headache, tinnitus, visual and auditory disturbances. Muscle twitching over the mouth angles, trismus and rigidity of extremities were also noted. Later in the course he became restless, agitative, hallucinative, talkative, and verbose with repetitious words. The whole course of the disorder lasted about 5 h. It was believed that lidocaine-induced CNS intoxication, manifested by psychotic reaction broke out. Treatment with thiopental was not very impressive. Also, we took this opportunity to discuss and review the toxic reaction associated with the use of lidocaine, its risk factors, mechanism, treatment and prevention. The complicated associations of lidocaine-induced CNS toxic reaction with central control of behavior and the neurotransmitter systems (adrenergic, dopaminergic and serotonin) were also touched.

Measurable sources of muscle tension include viscoelastic tone, physiological contracture (neither of which involve motor unit action potentials), voluntary contraction, and muscle spasm (which we define as involuntary muscle contraction). The latter two depend on motor unit action potentials to generate the tension. Total muscle tension is most accurately measured as stiffness. Thixotropy of muscle is an ubiquitous and functionally important phenomenon that is not commonly recognized. A clinical pain condition associated with increased muscle tension is tension-type headache, which is largely muscular in origin; it is often caused by myofascial trigger points, but not by a pain-spasm-pain cycle, which is a physiologically and clinically untenable concept. Clinical conditions associated with painful muscle spasm include spasmodic torticollis, trismus, unnecessary muscle tension, nocturnal leg cramps, and stiff-man syndrome.

A 78-year-old Japanese female was admitted to our hospital because of headache. Trismus, opisthotonus and convulsion appeared in the early morning on the second hospital day. She was diagnosed as tetanus based on these symptoms and the history of trauma on her left hand 6 days ago. A piece of bamboo was extracted from her left hand. However, Clostridium tetani was not identified. Thiamylal and mechanical ventilation were initiated combined with Pancronium, Diazepam and tetanus immune globulin. Gabexate Mesilate was also added for disseminated intravascular coagulation syndrome probably associated with rhabdomyolysis. By these treatments, she was healed leaving only a disuse syndrome of her limbs.

Salivary duct carcinoma (SDC) is a relatively uncommon malignant tumor of the salivary gland derived from the excretory duct reserve cells of the salivary glands. The authors report a case of SDC in a 34-year-old man who presented with trismus and left sided headache, radiologically by a left parapharyngeal mass involving into the left cavernous sinus and histologically by intraductal growth pattern with a cribriform appearance and comedonecrosis. Perineural invasion of the mandibular branch of trigeminal nerve is demonstrated. Clinical and pathologic features with relevant literatures are reviewed.

Ecstasy (3,4 methylenedioxymethamphetamine, or MDMA) is a recreational drug widely used among young people in discos or rave parties (1,2). MDMA is taken because it gives a feeling of euphoria, enhances energy and sociability, and heightens sensations and sexual arousal. However, several side effects have been described: headache, nausea, anorexia, xerostomia, insomnia, myalgia, trismus, and bruxism (2,3). More serious complications have also been reported, sometimes even leading to death: hyperthermia, disseminated intravascular coagulopathy, rhabdomyolysis, acute renal failure, liver failure, and water intoxication (2,3). We report the unusual case of a death due to an apparent allergic reaction following ecstasy ingestion.

Computer applications in head and neck reconstruction are rapidly emerging and create not only a virtual environment for presurgical planning, but also help in image-guided navigational surgery. This study evaluates the use of prefabricated 3-dimensional (3D) mirror image templates made by computer-simulated adjusted occlusions to assist in microvascular prefabricated flap insertion during reconstructive surgery. Five patients underwent tumor ablation surgery in 1999 and survived for 8 years. Four of the patients with malignancy received radiation therapy. All patients in this study suffered from severe malocclusion causing trismus, headache, temporomandibular joint pain, an unsymmetrical face, and the inability of further osseointegrated teeth insertion. They underwent a 3D computer tomography examination and the nonprocessed raw data were sent for computer simulation in adjusting occlusion; thus, a mirror image template could be fabricated for microsurgical flap guidance. The computer simulated occlusion was acceptable and facial symmetry obtained. The use of the template resulted in a shorter operation time and recovery was as expected. The computer-simulated occlusion-adjusted 3D mirror image templates aid in the use of free vascularized bone flaps for restoring continuity to the mandible. The coordinated arch will help with further osseointegration teeth insertion.

Inflammatory myofibroblastic tumour (IMT) is a rare distinctive neoplasm of intermediate biological potential with a predilection for the abdominopelvic region and lung of children and young adults. It is histologically composed of spindle cells (myofibroblasts) in a myxoid to collagenous stroma with a prominent inflammatory infiltrate composed primarily of plasma cells and lymphocytes. Its pathogenesis is controversial. Arising most commonly in the lungs, only two cases of histopathologically confirmed IMT originating from the infratemporal and pterygopalatine fossae have been documented in the literature. Neither had orbital involvement. We now report the first case of IMT originating from the infratemporal fossa with orbital extension in a previously well 31-year-old woman. The patient presented with a 5-month history of intermittent right-sided headaches, progressive trismus and right lower lid swelling. She then developed right proptosis, diplopia and paraesthesia in the ophthalmic and maxillary divisions of her trigeminal nerve. Magnetic resonance imaging showed a soft tissue mass occupying most of the right infratemporal fossa with extension into pterygopalatine fossa and orbit. Provisional diagnosis from an open biopsy was nodular fasciitis. She underwent surgical debulking of the infratemporal fossa and lateral orbit through a coronal and trans-oral approach with trans-zygomatic access via total zygomatic osteotomy. Review of intraoperative specimens revised the diagnosis to IMT. Further management included systemic corticosteroids and adjuvant radiotherapy.
