Four to twelve days following initial antibiotic treatment for a febrile illness, three adults suddenly experienced numbness and pain over the face and entire body. Each had received a penicillin or a semisynthetic derivative, and two patients also received other antibiotics. Signs appeared rapidly and included profound sensory ataxia, areflexia, and widespread sensory loss, primarily of large fiber modalities (proprioceptive sensibility). Slowed or absent sensory conduction was found. There was no weakness, and electrical study of muscle and motor nerve conduction was normal in all. The cerebrospinal fluid was acellular, and protein levels were elevated to 126 and 175 mg/dl in two cases and were normal in the other. Presently, all have a severe, static, residual sensory deficit. During follow-up of five years, no evidence of neoplastic disease or immunological disorder has appeared. Because of the rapid onset, widespread and pure sensory involvement, and poor recovery, the lesion is most likely confined to the dorsal root and gasserian ganglia (sensory neuronopathy). This pattern resembles that of the experimental lesions induced by doxorubicin and pyridoxine. It appears likely that either the previously administered antibiotics or the illness for which they were administered were of pathogenetic importance. We designate this previously unrecognized disorder the acute sensory neuronopathy syndrome and suggest that it represents a distinct, readily identifiable clinical entity.

A phase II study of Vindesine (VDS) was carried out in 20 patients with carcinoma of the lung (14 adenocarcinomas, 3 squamous cell carcinomas, 2 large cell carcinomas and 1 small cell carcinoma), and in 18 patients with metastatic pulmonary tumor (primary organ: 4 colons, 2 uteri, 2 lungs, one each tongue, pharynx, maxillary sinus, esophagus, mediastinum, bile duct, pancreas, kidney, rectum and sarcoma). VDS was given weekly by i. v. push at a dose of 3 mg/m2. Patients should be given at least three times of VDS for eligibility. Of 18 evaluable patients with carcinoma of the lung, 3 patients with adenocarcinoma showed a partial response. Response rates were 17% for patients with carcinoma of the lung, and 25% for 12 patients with adenocarcinoma. Two responders (uterine cervical carcinoma and mediastinal embryonal carcinoma) were observed in 14 evaluable patients with metastatic pulmonary tumor. In addition, one patient with metastatic maxillary sinus tumor showed a minor response. Major hematologic toxicities of VDS were leukopenia (less than 4000 cells/mm3--92%, less than 2000 cells/mm3--28%), anemia (less than 10.0 g/dl, 38%) and thrombocytopenia (less than 10 X 10(4) cells/mm3, 11%). Major non-hematologic toxicities were numbness (24%), constipation (11%), anorexia (21%), fever (16%) and liver dysfunction (21%). The dose limiting factor of VDS was leukopenia.

The results of five cases of ameloblastoma of the mandible treated by resection, preservation of the inferior alveolar nerve, and immediate bone grafting are reported. The incisions in all cases healed by first intention. Lip sensation on the operated side returned to normal in four to six weeks in four cases and slight numbness persisted to the eighth week in one case. All patients were followed postoperatively for 13-15 years. In one case the tumor recurred in the mucous membrane seven years after surgery at the original intraoral site and invaded the underlying bone graft. The indications and contraindications for surgery and details of the procedures, including measures to prevent recurrence, are presented.

The clinical appearance of foramen magnum tumor is protean and, even at the stage when serious neurological deficits are present, the lesions are often misdiagnosed as another disease, especially cervical spondylosis and multiple sclerosis, and patients may undergo improper concervative or even surgical treatments. The best guarantee against misdiagnosis, we believed, was to establish a definition of "Foramen Magnum Syndrome" to facilitate the recollection of its peculiar clinical findings. "Foramen Magnum Syndrome" is composed of: 1. Cape distribution of sensory loss; 2. Atrophy of the intrinsic muscles of the hands; 3. Neck or suboccipital pain; 4. Dysesthesia of the hands (numbness, tingling, and cold sensation); 5. Eleventh cranial nerve palsy; 6. Stereoanesthesia. (Remember the mnemonic CANDES or DESCAN) Among these, cape distribution of sensory loss, eleventh cranial nerve palsy and cold dysesthesia (not numbness or tingling sensation) are of great importance for topological diagnosis. We also pointed out the similarities between the clinical picture of syringomyelia and that of the advanced stage of foramen magnum tumor. The syringomyelic syndrome, often seen in Arnold-Chiari malformation and basilar impression, has been attributed to the concurrent syrinx of cervical cord. But the clinical analysis of foramen magnum tumors showed that this is not always true and that compressive lesions at the foramen magnum alone can cause syringomyelic syndrome.

A total of 100 patients with American Burkitt's lymphoma (AMBL) (mean age, 15 years; M:F ratio 3:1; 3% black) have been treated at the National Cancer Institute since 1964. Eighteen of these had jaw involvement, 16 at presentation and 2 at relapse (mean age, 16 years; M:F ratio 1.6:1). None of these 18 patients was black. Of the 16 patients presenting initially with jaw tumors, 14 were first evaluated by their dentist; 8 were 16 years of age or older (adults) and 6 were younger than 16 years of age (children). Toothache and perioral numbness were the most frequent findings in adults, whereas toothache, loose teeth, intra-oral and extra-oral swelling were the most common complaints in children. Ten patients were treated with antibiotic therapy and/or dental extractions for presumed tooth infection. The distribution of jaw lesions was: unilateral mandibular (7), unilateral maxillary (4), bilateral mandibular (5), and four quadrants (2). Radiologic evaluation was abnormal in all 17 cases evaluated. Only three patients (all children) had disease limited to the jaw. Four of eight children and 3 of 10 adults are long-term survivors with a median follow-up of seven years (range, 2-15 years). American Burkitt's lymphoma with jaw involvement differs from African Burkitt's lymphoma (AFBL) with jaw involvement in a number of ways: (1) the incidence of jaw tumors in adults is similar to that in children; (2) the incidence of jaw tumors is not greater in males; (3) tumor is considerably more limited in extent with a single quadrant mandibular lesion being the most common presentation; and (4) clinical presentation also differs, with toothache and perioral numbness, uncommon in AFBL, being the most frequent complaints. These marked differences in the frequency and clinical characteristics of jaw tumor of AMBL and AFBL are consistent with other findings indicating that these diseases may differ phenotypically.

Clinical, electrodiagnostic, and morphological studies were performed on three patients with localized hypertrophic neuropathy (LHN). LHN is characterized clinically by slowly progressive motor mononeuropathy without significant pain or numbness. Nerve conduction studies and needle electrode examination show severe focal motor and sensory axonal loss. Morphological findings in the localized areas of enlarged nerves are different from those of generalized hypertrophic neuropathy, entrapment neuropathy, and neurofibroma, and consist of primary perineurial cell hyperplasia. The tumor is thus a perineurioma. This rare tumor can occur both in generalized neurofibromatosis and in isolated form and appears to be the cause of localized hypertrophic neuropathy.

A case is reported of solitary schwannoma involving the skull base with extension into the middle cranial fossa and parasellar region. The patient presented with an exophthalmos and ipsilateral facial numbness. The tumor was successfully excised via a two-stage procedure involving an initial intracranial and subsequent transmaxillary approach. The relevant literature on the presentation and treatment of schwannomas of the skull base with intracranial extension is also reviewed.

A case of reticulum cell sarcoma of the mandible in a 77-year-old woman has been presented. The patient said that she experienced pain and numbness of the affected area (mandible and lip) for two months and then a small swelling appeared. The tumor was first seen in the soft tissues of the right side of the mandible, but radiographic findings in the bone allowed us to conclude that the tumor originated in the mandible, and spread to soft tissue.

A 32-year-old female presented with medulla oblongata germinoma manifesting as numbness in the extremities. Computed tomography demonstrated a mass in the medulla oblongata expanding into the fourth ventricle. The tumor was partially removed. Immunohistochemical staining of the tumor specimen demonstrated large epithelioid cells positive for placental alkaline phosphatase, and syncytiotrophoblastic cells positive for beta subunit of human chorionic gonadotropin. Some epithelioid cells were also positive for cytokeratin. She received 44 Gy of irradiation to the posterior fossa and 20 Gy whole spinal irradiation. No signs of recurrence have occurred for 9 years. Patients with medulla oblongata germ cell tumor are comparatively older than those with other intracranial germ cell tumors and have two X chromosomes. All tumors were diagnosed as germinoma, and caused symptoms of involvement of the lower cranial nerves and the lower brain stem without pyramidal tract signs.

A case of NHL which has been in long-term remission following vigorous treatment for CNS relapse with intrathecal administration of Ara-C and focal irradiation to the brain is presented. The patient was a 61-year-old man, who was successfully treated with CHOP followed by MACOP-B for diffuse large cell NHL in 1988. Five months later he was admitted to our hospital because of loss of visual acquity and numbness in the right upper and lower extremities. The presence of lymphoma cells in CSF, abnormal shadow in the left frontal lobe on a cranial CT scan and MRI scan, and positive Ga scintigraphy yielded a diagnosis of CNS relapse of NHL. Twenty one whole brain and additional 1.0Gy to the left frontal lobe of irradiation were performed. Eight days later the left tumor disappeared. Neurological remission was obtained and has continued until now.
