BACKGROUND: Primary effusion lymphoma (PEL) is a rare malignancy usually associated with HIV infection. Management and outcomes are poorly understood. METHODS: The medical records of all patients diagnosed with HIV-associated PEL at our institution between 1999 and 2014 were reviewed. Patients were followed till death, treatment failure or loss of follow-up. RESULTS: Twelve patients with PEL were identified during the 15 year study period; 9 had HIV infection. All 9 were male; median age was 45 years. All presented with local symptoms and were diagnosed with PEL a median of 11 years after HIV diagnosis. Location was pleural (3), pericardial (3), peritoneal (1) and extracavitatory (2). By definition, all had Ann Arbor stage 4 at diagnosis. Median follow-up was 34 months. Two patients had poor performance status and were unable to get chemotherapy. Seven patients had a complete remission (CR) and two died within 1 month of diagnosis. The median CD4 levels at PEL diagnosis in patients with poor versus good outcomes were 54 cells/mm3 (range, 26-82 cells/mm3) and 211 cells/mm3 (range, 73-800 cells/mm3). In contrast, the median lactate dehydrogenase (LDH) levels at PEL diagnosis with poor versus good prognosis were 1074 U/L (range, 703-1445 U/L) and 283 U/L (range, 156-760 U/L). CONCLUSIONS: Given its rarity, our knowledge of PEL relies solely on case reports and case series. Prompt HAART and chemotherapy may be effective in HIV- associated PEL and good outcomes are possible. LDH and CD4 may be possible prognostic factors in PEL.

Acute lymphoblastic leukemia (ALL) is a haematological malignancy that can involve the central nervous system (CNS). Less than 10 % of patients with ALL have CNS involvement at presentation. The cranial nerve most commonly affected is cranial nerve VII although bilateral involvement is rare. Management and outcomes of these patients are not well understood. Moreover bilateral Bells palsy as a presenting symptom of ALL is extremely uncommon. We report a very unusual presentation of ALL with bilateral facial nerve palsy, and discuss the management strategies and outcomes for patients with ALL that present with cranial nerve palsies.
RESUMEN
Sarcoidosis and Crohns disease have been associated with increased long term risk of lymphoproliferative disorders, including lymphomas. Newly developed lymphadenopathy in a patient with these disorders should prompt pathological evaluation. Castleman's disease is a lymphoproliferative disorder characterized by enlarged hyperplastic lymph nodes with regressed follicles surrounded by expanded mantle zones of small lymphocytes, and interfollicular vascular proliferation in the hyaline-vascular type. Similar to sarcoidosis and Crohns disease, its etiology is incompletely understood, although immune dysregulation, genetic factors and infectious and environmental factors are thought to play a role in all three diseases. Interleukin-6 is a possible pathological common factor between these three disease processed. Unicentric, hyaline-vascular type Castleman's disease can be treated successfully with complete surgical resection. We report a patient with long history of sarcoidosis and Crohns disease with newly developed lymphadenopathy which was found to be due to Castleman's disease.

We present a patient with autoimmune autonomic ganglionopathy (AAG) who had persistently positive ganglionic nicotinic acetylcholine receptor antibody levels despite immunosuppressive therapy. Rituximab-based therapy for an incidental lymphoma was associated with prolonged symptomatic and serological control of AAG.

A 61-year-old man with relapsing-remitting multiple sclerosis developed extranodal large B-cell lymphoma of the stomach following monthly natalizumab infusions for 6 years. Development of lymphoproliferative disorders increases with chronic use of immunosuppression. Cases of primary central nervous system lymphoma as well as one case of peripheral T-cell lymphoma have previously been reported with natalizumab use. Given the absence of a known association between multiple sclerosis and extranodal presentations of diffuse large B-cell lymphoma, a causal association with natalizumab administration cannot be excluded.
RESUMEN
Non-verbal communication is an important component of the physician-patient interaction. Oncology patients face specific emotional and psychological issues requiring additional physician emotional support. Multiple studies in oncology patients have revealed that patients perceive physicians seated during the medical interview to be more compassionate, caring, and likely to spend more time with the patients. These are all associated with improved patient outcomes. Barriers to sitting may be due to those imposed by time, space, and reduced perceived benefit of sitting by the physician. Although a sitting posture alone is unlikely to compensate for poor communication skills, assessing patient preference to physician posture, and following their preference, can be a simple way of improving communication, and thus patient outcomes, especially in oncology patients. The widespread introduction of the electronic medical record (EMR) system over the last decade has added a "third wheel" to the original dyadic physician-patient relationship. Physician posture and eye gaze towards to the EMR and its components has a deleterious effect on communication. Appropriate training and sensitization in this regard should be provided for physicians.

Prostatic adenocarcinoma is the most common cancer in men, but only a handful of cases of prostatic angiosarcoma have been reported in the literature. Prior radiation therapy for prostatic adenocarcinoma has been hypothesized to be a risk factor for angiosarcoma. The increasing practice of prostate cancer screening and the use of radiation therapy for management of prostatic adenocarcinoma will likely lead to more cases of prostatic angiosarcoma. Diagnosis is made by tissue sampling. Optimal management of these aggressive tumors remains to be defined and outcomes are poor with a high 1-year mortality. Primary care physicians and urologists should be aware of this rare entity and refer these patients to specialist centers where they can be managed by a multidisciplinary team. We report a case of angiosarcoma of the prostate gland diagnosed in a male presenting with lower urinary tract symptoms 5 years after brachytherapy for prostate adenocarcinoma.
RESUMEN
Although rare, clinicians and patients must be aware that therapy related malignancies, specifically acute myeloid leukemia (AML), can occur as a complication of adjuvant chemotherapy for breast cancer. Vigilance for signs and symptoms is appropriate. AML with t (8;16) is a specific translocation leading to formation of a fusion protein (MYST3/CREBBP). The MYST3/CREBBP AML tends to develop within 2 years of adjuvant chemotherapy, especially for breast cancer, without preceding myelodysplasia. It usually presents with disseminated intravascular coagulation and osteolytic lesions and has a poor prognosis despite aggressive resuscitation and therapy. With the increasing use of adjuvant chemotherapy for breast cancer, we are seeing a definite increase in the incidence of therapy related myelodysplastic syndromes and AML. One must keep this complication in mind while counseling and following up breast cancer patients who have received adjuvant chemotherapy. New osteolytic bone lesions in a patient with history of breast cancer do not necessarily mean metastatic disease and should be fully evaluated.

OBJECTIVES: This study aimed to estimate outcomes of splanchnic vein thrombosis (SVT) in hospitalized patients with acute pancreatitis (AP). METHODS: This was a retrospective study (January 1996 to December 2006) via chart review. RESULTS: Over 10 years, 1.8% (45/2454) of patients with AP with a mean (SD) age of 58 (15) years were diagnosed with SVT. Splenic vein thrombosis was the most common form of SVT (30/45 patients, 67%). Seventeen patients were anticoagulated with heparin, when the SVT was diagnosed in the acute stage followed by oral anticoagulation (AC). The thrombosis that was most commonly anticoagulated was portal vein thrombosis in 11 (65%) of 17 patients. Of 17 patients in the AC group, 2 (12%) showed recanalization as compared with 3 (11%) of 28 patients in the non-AC group (P > 0.05). The mortality was 3 (7%) of 45 (2 from the AC group versus 1 in the non-AC group, P > 0.05). Two of these died of multiorgan failure, and the other, from septic shock. None of the deaths were due to bleeding complications. CONCLUSIONS: Splanchnic vein thrombosis occurred in 1.8% patients of AP. The use of AC was reasonably safe with no fatal bleeding complications. However, there was no significant difference in the recanalization rates in those with and without AC.
