Paraneoplastic movement disorder in a patient with non-Hodgkin's lymphoma and CRMP-5 autoantibody.

The paraneoplastic autoantibody, collapsin response-mediator protein (CRMP)-5 immunoglobulin G (IgG), is specific for neuronal cytoplasmic CRMP-5, and is usually associated with small-cell lung carcinoma or thymoma. We report on details of a movement disorder that followed anti-B-cell therapy in a patient with lymphoma, and was accompanied by CRMP-5 IgG.     

Esthesioneuroblastoma in a young child. Case report

Esthesioneuroblastoma is an uncommon malignant neoplasm that arises from olfactory mucosa, often with intracranial extension.A case report of the youngest victim in the literature (2-year-old boy) is presented.     

Pathological changes in testes and liver of male albino rats after dermal exposure to DDVP insecticide.

Exposure of male albino rats to DDVP insecticide at sublethal dose of 30 mg/kg/day through dermal painting for a period of 90 days didn't show any intoxication symptoms or mortality. However, cytopathological changes in testicular and liver tissues were evident. There was a positive correlation between the degree of cellular damage and the period of insecticide administration. In general, damages were prominent in rats treated for 30 days or more. Histological examination of testes showed degenerative seminiferous tubules and fewer leydig cells. Hepatic cells were congested, atrophied and showed different stages of necrobiotic changes. This suggests a great care and caution for workers during different phases of DDVP insecticide handling.     

Bone scintigraphy in tuberculous sacroiliitis

Radionuclide bone imaging is becoming increasingly important in the evaluation of musculoskeletal pain of uncertain cause. A case in which Tc-99m MDP bone imaging was employed to investigate complaints of low back pain is presented. Scan abnormalities directed clinicians towards appropriate further workup and diagnosis of unilateral tuberculous sacroiliitis.     

Radiologic appearance of non-traumatic intracranial hemorrhage]

The diagnosis of nontraumatic intracranial hemorrhage is currently made by computed tomography and is rarely problematic. The causes of bleeding are very numerous. It is important to determine the cause of the hemorrhage promptly, because there may be a recurrence of bleeding. Guidelines for radiologists are proposed and discussed here.     

Neurotoxic effects of MDMA (“ecstasy”) administration to neonatal rats

3,4-Methylenedioxymethamphetamine damages fine serotonergic fibers and nerve terminals in adult organisms. Developing animals seem to be less susceptible to this effect, possibly due to a lack of drug-induced hyperthermia. We tested this hypothesis by producing hyperthermia in neonatal rats for 2 h after each of twice-daily MDMA (10 mg/kg s.c.) or saline injections administered from postnatal days 1–4. Other drug-treated and control litters were maintained at normothermic temperatures following injection. Changes in forebrain serotonergic innervation were assessed at postnatal day 25 (serotonin transporter binding and serotonin levels), postnatal day 60 (serotonin transporter binding), and 9 months of age (serotonin transporter immunohistochemistry). We also determined the influence of MDMA treatment on apoptotic activity by means of immunohistochemistry for cleaved caspase-3 at postnatal day 5. The hippocampus showed significant MDMA-related reductions in serotonergic markers at postnatal day 25 and postnatal day 60. At 9 months, there was no effect of prior MDMA exposure on serotonin transporter-immunoreactive fiber density in the hippocampus; however, significant reductions in fiber density were observed in two neocortical areas and a hyperinnervation was found in the caudate-putamen and nucleus accumbens shell. MDMA treatment also produced a two-fold increase in the number of cleaved caspase-3-immunoreactive cells in the rostral forebrain and hippocampus. All of these effects were completely independent of pup body temperature. These findings demonstrate that neonatal MDMA administration exposure stimulates apoptotic cell death in various forebrain areas and also leads to a long-term reorganization of the forebrain serotonergic innervation. Consequently, offspring of MDMA-using women may be at heightened risk for abnormal neural and behavioral development.     

Hemoperitoneum secondary to rupture of cystic artery pseudoaneurysm

BACKGROUND:Spontaneous hemoperitoneum of hepato- biliary origin is commonly due to hemorrhage from a liver tumor.It is rarely caused by spontaneous rupture of aneurysm in visceral arteries. METHODS:We report an unusual case of hemoperitoneum caused by rupture of cystic artery pseudoaneurysm,and also outline the approach to its management through surgical and radiological methods. RESULTS:In our patient,the pseudoanurysm was initially treated with percutaneous thrombin injection.However this method of treatment failed after initial success.The pseudoanurysm was finally obliterated successfully using microcoil embolization. CONCLUSIONS:The mainstay of treatment of cystic artery pseudoaneurysm is cholecystectomy and ligation of the aneurysm.Recent publications showed success in using microcoil embolisation.In this case we also outline the use of percutaneous thrombin injection as a definitive treatment method and discuss its success or failure as a new method of treatment.     

Inventory of plants used in traditional medicine in Somalia. III. Plants of the families Lauraceae-Papilionaceae.

Thirty-five plants are listed, which are used by traditional healers in the central and southern parts of Somalia. For each species are listed: the botanical name with synonyms, collection number, vernacular name, medicinal use, preparation of remedy and dosage. Results of a literature survey are also reported including medicinal use, substances isolated and pharmacological effects.     

Adenocarcinoma with simultaneous squamous carcinomas of the larynx

Background. Primary adenocarcinoma of the larynx is a rare neoplasm. The incidence is reported as less than 1% of all laryngeal neoplasms in multiple series. Simultaneous primary adenocarcinoma and a solitary squamous cell carcinoma of the larynx is even rarer and only one case has been found on review of the literature. Methods. A case report of a 74-year-old man with a history of right-sided throat pain, odynophagia, and progressive hoarseness is presented with a review of the literature pertaining to this unusual case. Results. The patient was found to have three distinctly separate laryngeal lesions on direct laryngoscopy. Histopathologic diagnosis of adenocarcinoma was made on one of the three biopsied sites with the other sites being squamous cell carcinoma. Following Combined radiotherapy and surgical treatment, the patient has remained free of disease. Conclusions. Adenocarcinoma of the larynx is an infrequent and lethal disease. This case report and a review of the literature demonstrate that aggressive surgical management is indicated, although still may not result in improved survival. © 1994 John Wiley & Sons, Inc.     

Ultrasonic diagnosis of non-calculous intraluminal obstruction in the extrahepatic bile ducts. Apropos of 8 cases

Ultrasound examination in 8 patients with occlusive jaundice demonstrated non-lithiasic extrahepatic intracanalar obstacles, a malignant tumor in 4 and a non-tumoral process (granuloma on suture thread, ball sludge, hemobilia in 2 cases) in the other 4. Analysis of echographic data suggested possible differential diagnosis criteria for these two types of occlusion.
