1/200. association of body cavity-based lymphoma and human herpesvirus 8 in an hiv-seronegative male. Report of a case with immunocytochemical and molecular studies.BACKGROUND: Recently lymphomas arising primarily in serosal surfaces have been found in patients with advanced acquired immunodeficiency syndrome (AIDS), but they very rarely seem to occur in human immunodeficiency virus (hiv)-negative patients. Studies on a subset of these lymphomas suggested that they represent a distinct entity associated with Kaposi's sarcoma-associated herpesvirus or human herpesvirus 8 (HHV-8). CASE: An 83-year-old, hiv-negative male was admitted to the hospital with a massive pleural effusion. Abdominal and chest computed tomographic scanning was normal. Cytologic analysis of the pleural effusion revealed a large cell, non-Hodgkin's lymphoma. polymerase chain reaction analyses on genomic dna from the pleural effusion demonstrated the presence of HHV-8 sequences in the absence of Epstein-Barr virus. CONCLUSION: It is possible and advantageous to diagnose body cavity-based lymphoma with a combination of cytologic, immunocytochemical and molecular studies of the pleural effusion in conjunction with clinical and radiographic information.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
2/200. Complicated delirium in a cancer patient successfully treated with olanzapine.delirium is common among cancer patients, especially those with advanced disease. Typical treatment involves addressing the underlying cause if possible; eliminating nonessential and/or other drugs that can worsen confusion, manipulating the environment; and administering antipsychotic drugs to control symptoms and agitated behavior, and attempt to clear the patient's sensorium. The newer atypical antipsychotics may have potential in the treatment of delirium and also have the added benefit of causing less akithisia and other extrapyramidal side effects. This is illustrated by the case of a 59-year-old woman with leukemia and pain of unclear etiology who developed a delirium and a moderate to severe extrapyramidal syndrome (EPS) in the setting of escalation of her pain medications and concomitant escalation of prochlorperazine. The patient presented with confusion and moderate to severe cogwheeling rigidity, masked facies, bradykinesia, and tremor. Additionally, the patient had a relatively recent history of subdural hematoma and one seizure. Conservative management including eliminating multiple nonessential medications (including the prochlorperazine); changing her opioid analgesic; providing a 24-hour companion: and administering low doses of haloperidol (0.5 mg-2.0 mg) were not effective in treating the patient's delirium. The patient's EPS was dramatically worse following haloperidol doses. After approximately I week without improvement, the patient was started on olanzapine 5 mg daily with initial improvement but with residual confusion in the evenings and overnight. The dose was titrated up to 10 mg nightly with 2.5 mg as needed during the day. After 3 days on this regimen, the patient's mental status exam was normal and she was discharged home. We discuss the potential utility of this atypical antipsychotic in the palliative care setting.- - - - - - - - - - ranking = 4.6589089494884keywords = pain (Clic here for more details about this article) |
3/200. Acute herpetic neuralgia and postherpetic neuralgia in the head and neck: response to gabapentin in five cases.BACKGROUND AND OBJECTIVES: The clinical presentations and pharmacologic management of three patients with acute herpetic neuralgia (AHN) and two patients with postherpetic neuralgia (PHN), confined to the head and neck region, are described. methods: Two patients had pain in the ophthalmic division of the trigeminal nerve, two had pain confined to the C2-C4 dermatomes, and one patient had C2 pain with radiating and referred pain to the second and third divisions of the trigeminal nerve. RESULTS: Gabapentin, an anticonvulsant drug, was effective in treating these patients, including the two cases of AHN. All patients reported complete pain relief after titration with gabapentin up to 1,800 mg/d. The patients noted a dose-dependent decrease in pain almost immediately after starting gabapentin. Specifically, reduction in the frequency and intensity of allodynia, burning pain, shooting pain, and throbbing pain were noted. None of the patients experienced side effects from the drug. CONCLUSIONS: In view of the results in these patients, blinded, controlled studies are needed to determine the efficacy of gabapentin for treating AHN and PHN.- - - - - - - - - - ranking = 20.965090272698keywords = pain (Clic here for more details about this article) |
4/200. Cerebral and renal embolization after lymphography in a patient with non-Hodgkin lymphoma: case report.An unusual case of lipid embolization to brain and kidney after lymphography in a patient with non-Hodgkin lymphoma of the upper anterior mediastinum is reported. Contrast material-enhanced echocardiography demonstrated a right-to-left shunt to the left atrium without evidence of a patent foramen ovale. Echo contrast particles were transiently present within the tumor surrounding the great vessels.- - - - - - - - - - ranking = 0.37482939537287keywords = upper (Clic here for more details about this article) |
5/200. Pulmonary intravascular lymphomatosis: presentation with dyspnea and air trapping.Intravascular lymphomatosis (IVL) is a rare lymphoid neoplasm that is typically of B-cell lineage and characterized by proliferation of malignant cells within small arterioles, capillaries, and venules. We report a patient with pulmonary IVL who presented clinically with progressive dyspnea, fever, and a dry cough. Pulmonary function tests revealed a marked decrease in diffusion capacity with airflow obstruction and severe air trapping. High-resolution CT (HRCT) of the chest with inspiratory and expiratory images revealed mosaic attenuation consistent with air trapping. Transbronchial biopsies revealed the diagnosis of IVL with capillary expansion in the alveolar and peribronchiolar interstitial tissue. IVL should be considered in the differential diagnosis of a patient with an interstitial lung disease, air trapping on pulmonary function tests, and mosaic attenuation on HRCT. Transbronchial biopsies may be the initial diagnostic procedure of choice.- - - - - - - - - - ranking = 1keywords = chest (Clic here for more details about this article) |
6/200. Management of pleural effusions in children with malignant lymphoma.PURPOSE: The aim of this study was to determine potential problems in the diagnosis and management of children with pleural effusions and malignant lymphoma as well as the efficacy of thoracentesis. methods: The case histories of six children with malignant lymphoma who presented with pleural effusions were reviewed. Thoracentesis was performed using the Seldinger technique. RESULTS: Four of the children presented with symptoms and chest radiograph findings similar to pneumonia. A large mediastinal mass was present in two children. Pleural fluid analysis resulted in a definitive diagnosis of lymphoma in five of the six children. Two of the children had symptoms of reexpansion pulmonary edema after removal of pleural fluid. An empyema developed in one child after thoracotomy and chest tube placement. Reaccumulation of pleural fluid was common before initiating chemotherapy. CONCLUSIONS: Malignant pleural effusions frequently are present in children with non-Hodgkin's lymphoma. They may present with respiratory distress because of the size of the effusion, the mediastinal mass, or both. Management of these pleural effusions is associated with potential complications, some of which are life threatening. Thoracentesis is the initial diagnostic and therapeutic procedure of choice. The use of a Seldinger technique for thoracentesis has proved useful and safe. In patients with large effusions, aggressive removal of the pleural fluid may be followed by reexpansion pulmonary edema.- - - - - - - - - - ranking = 2keywords = chest (Clic here for more details about this article) |
7/200. Fine needle aspiration cytology of primary non-Hodgkin's lymphoma of the tongue. A case report.BACKGROUND: Fine needle aspiration cytology (FNAC) of extranodal non-Hodgkin's lymphoma of the tongue has rarely been described. CASE: A 47-year-old male was referred to the cytology laboratory for FNAC of a 3-cm-diameter swelling on the dorsum of the tongue, with a primary clinical diagnosis of soft tissue tumor. FNAC smears showed discrete, monomorphic, round to oval cells with scanty, deep blue cytoplasm. The nuclear margin was regular, with occasional prominent nucleoli and fine nuclear chromatin. The background showed many lymphoglandular bodies. The cells were strongly positive for leukocyte common antigen. A cytologic diagnosis of high grade non-Hodgkin's (NHL) was offered and subsequently confirmed by histopathology. CONCLUSION: Primary NHL of the tongue is relatively rare. As there are no characteristic clinical features of extranodal NHL of the tongue, FNAC may be useful for rapid diagnosis and management of such cases.- - - - - - - - - - ranking = 0.60324397685338keywords = back (Clic here for more details about this article) |
8/200. Primary multifocal lymphoma of bone presenting as hypercalcemic crisis: report of a rare manifestation of extranodal lymphoma.Primary non-Hodgkin's lymphoma of bone is uncommon and usually manifests clinically as localized bone pain. Here we report a woman who presented with hypercalcemic crisis and extensive investigation revealed a primary multifocal lymphoma of bone. The course of the disease was very aggressive and despite intensive supportive care and urgent chemotherapy the patient died within 1 month. Since her blood PTH and calcitriol levels were suppressed and her parathyroid-hormone-related peptide (PTHrp) was mildly elevated, we believe that release of cytokines combined with PTHrp, as well as extensive osteolytic lesions, were the causes of the hypercalcemia. This is an unusual presenting symptom of lymphomas and to the best of our knowledge severe symptomatic hypercalcemia and crisis has never been reported in primary lymphoma of bone before.- - - - - - - - - - ranking = 2.3294544747442keywords = pain (Clic here for more details about this article) |
9/200. Hypophyseal non-Hodgkin's lymphoma presenting with diabetes insipidus: a case report.We report the case of a 64 year old male patient with a history of ischemic heart disease who underwent surgery for an abdominal mass. The histological diagnosis was highly malignant non-Hodgkin's lymphoma. After surgery the patient was admitted to our Department and received 6 courses of chemotherapy according to the COP schedule, followed by radiotherapy to the left upper abdominal region and ipsilateral lung base. The patient achieved partial remission. One month later he began to complain of left axillary lymphadenomegaly, polydipsia and polyuria. A NMR brain scan showed a hypophyseal mass. The patient was treated with DDAVP and chemotherapy with the PRO-MACE protocol; the polyuria and lymphadenomegaly disappeared and the size of the hypophyseal mass reduced markedly. The clinical picture was, therefore, attributed to a hypophyseal localization of the non-Hodgkin's lymphoma, which is a very rare manifestation of lymphomatous spread to the central nervous system. Our case is also interesting because it shows that a favorable outcome can be obtained with chemotherapy, provided that the latter is sufficiently aggressive. This is not necessarily the case with radiotherapy which may also be followed by late and severe neurologic sequelae.- - - - - - - - - - ranking = 0.37482939537287keywords = upper (Clic here for more details about this article) |
10/200. intussusception in the older child- suspect lymphosarcoma.Examination of the records of 378 children with intussusception at our institution revealed that 29 cases were caused by an identifiable intestinal lesion. A Meckel's diverticulum was the causative agent in 21 children, all of whom were under 2 yr of age. A previously undiagnosed ileal lymphosarcoma produced the intussusception in six other children, all between 6 1/2 and 9 yr of age. Our experience indicates that any child over 6 yr of age with the clinical findings of colicky abdominal pain, bloody stools, and a palpable mass plus the radiographic evidence of intussusception must be considered to have ileal lymphosarcoma until proven otherwise. Hydrostatic reduction of the intussusception must be accompanied by extensive small bowel reflux of barium in order to effectively rule out a small intestinal lesion. If this is not accomplished, surgery should be planned with the suspicion that a malignancy may be present. If this suspicion is confirmed by frozen section, the operation procedure should include wide surgical excision of the lesion along with the regional lymph nodes.- - - - - - - - - - ranking = 6.3202272575167keywords = abdominal pain, pain (Clic here for more details about this article) |
