Two girls with mixed connective tissue disease (MCTD) were treated in our hospital in the past 5 years. Patient 1, a 10-year-old girl presenting with migratory arthralgia, had an initial diagnosis of juvenile rheumatoid arthritis. Muscle weakness with elevated levels of creatine kinase and liver enzymes, sclerodactyly, Raynaud's phenomenon and heliotrope sign developed subsequently in the following 3 years. Patient 2, a 13-year-old girl, had been treated for suspected systemic lupus erythematosus since 9 years of age. She presented with lymphadenopathy, arthralgia, pericardial effusion, and paralytic ileus. The symptoms waxed and waned. Sclerodactyly, Raynaud's phenomenon, proteinuria, and hypertension were also noted. Both patients had high serum titers of antinuclear antibody (speckled pattern, 1:5120) and were seropositive for antiribonuclear protein antibody. Intravenous immunoglobulin, prednisolone, cyclosporine A, and nonsteroidal anti-inflammatory drugs (NSAIDs) were given to patient 1. Patient 2 received cyclosporine A, prednisolone, and methylprednisolone pulse therapy. The disease has been well controlled for 2 years by low-dose immunosuppressants and NSAIDs. MCTD is a rare juvenile rheumatic disease: early identification and appropriate treatment can improve the disease outcome.

Although cancer has an annual incidence of only about 150 new cases per 1 million U.S. children, it is the second leading cause of childhood deaths. Early detection and prompt therapy have the potential to reduce mortality. Leukemias, lymphomas and central nervous system tumors account for more than one half of new cancer cases in children. Early in the disease, leukemia may cause nonspecific symptoms similar to those of a viral infection. Leukemia should be suspected if persistent vague symptoms are accompanied by evidence of abnormal bleeding, bone pain, lymphadenopathy or hepatosplenomegaly. The presenting symptoms of a brain tumor may include elevated intracranial pressure, nerve abnormalities and seizures. A spinal tumor often presents with signs and symptoms of spinal cord compression. In children, lymphoma may present as one or more painless masses, often in the neck, accompanied by signs and symptoms resulting from local compression, as well as signs and symptoms of systemic disturbances, such as fever and weight loss. A neuroblastoma may arise from sympathetic nervous tissue anywhere in the body, but this tumor most often develops in the abdomen. The presentation depends on the local effects of the solid tumor and any metastases. An abdominal mass in a child may also be due to Wilms' tumor. This neoplasm may present with renal signs and symptoms, such as hypertension, hematuria and abdominal pain. A tumor of the musculoskeletal system is often first detected when trauma appears to cause pain and dysfunction out of proportion to the injury. Primary care physicians should be alert for possible presenting signs and symptoms of childhood malignancy, particularly in patients with Down syndrome or other congenital and familial conditions associated with an increased risk of cancer.

Renovascular hypertension is an important but not so common cause of hypertension. Rarely the extrinsic compression of renal arteries by retroperitoneal structures may be responsible for hypertension. Lymphadenopathy due to metastasis has been reported to cause renovascular hypertension. The present case reports hypertension which resulted from tubercular abdominal lymphadenopathy in a twenty one years male. The patient was treated with antitubercular medication with which his hypertension also got controlled. An unusual cause of hypertension and a rare complication of tuberculosis is reported.

A 65-year-old male was admitted for evaluation of severe anaemia, recurrent epistaxis, axillary lymphadenopathy, and hepatomegaly. The diagnosis of Waldenstrom's macroglobulinaemia was made on the basis of clinical and laboratory findings. The patient developed intracerebral haemorrhage without associated hypertension and with normal coagulation profile.

A 77-year-old woman was referred to our hospital because of leukocytosis and leukoblastosis in September 1999. She was healthy except for hypertension, and no abnormal findings in the peripheral blood had been observed up to December 1998. Physical examination revealed neither hepatosplenomegaly nor superficial lymphadenopathy. A bone marrow film showed massive proliferation of blast cells (87.8%), some of which contained coarse basophilic granules (38.6%). The cells were negative for peroxidase and esterase (alpha-naphtyl butyrate and ASD-chloroacetate) staining, but the granules showed metachromasia upon toluidine blue staining. As immunophenotypic analysis of the cells showed double positive for CD13/CD19 but negativity for CD33, this case did not meet the diagnostic criteria for biphenotypic acute leukemia. Chromosome and gene analysis showed positivity for the Ph1 chromosome with minor bcr/abl chimeric mRNA. A homogenate of the peripheral mononuclear cells demonstrated a high concentration of histamine. Electron microscopy analysis confirmed that some of the blast cells contained dense granules, which closely resembled "immature basophil granules" morphologically. These results suggested that the blast cells showed basophilic differentiation. As the clinical course and peripheral blood findings were different from blastic crisis of chronic myelogenous leukemia (CML) and CML with minor bcr/abl chimeric mRNA, the present case was diagnosed as "multiphenotypic acute leukemia", a type of acute basophilic leukemia classified by Duchayne.

The use of silicone in patients with immune-compromising diseases is controversial because of fears that there may be inflammatory reactions against the material. We report the case of a patient who suffered from cutaneous sarcoidosis with bihilar lymphadenopathy and obesity (110 kg; BMI, 38 kg/m2) that was exaggerated by cortisone therapy. The patient underwent adjustable gastric banding because of aggravating comorbid hypertension and hyperlipidemia. Six months postoperatively, she had achieved an excess weight loss of 33%. During this period, she had a relapse of scar sarcoidosis of the right elbow and bilateral hilar lyphadenopathy. Although she was treated with a double dose of cortisone (8 mg daily), the scars from the laparoscopy as well as those in the gastric region adjacent to the band remained unaffected. We therefore believe that preexisting immune-compromising diseases are not an absolute contraindication against gastric banding, particularly since our patient experienced a notable improvement in her quality of life.

A 73-year-old African American female presented to our clinic with painful lower extremity lesions of 2 weeks duration. She was in her usual state of health until 3 months prior to presentation when she reported symptoms of fatigue and weakness. She also noticed an enlarging mass on the left side of her neck. She denied fevers, chills, night sweats or cough. Her symptoms were unresponsive to a course of oral dicloxacillin. The neck mass enlarged over 8 weeks and she was referred to our institution for evaluation. CT scan of the neck showed an enlarged lymph node. Ten days prior to her presentation in dermatology, a fine needle aspirate of the enlarging lymph node revealed necrotizing granulomas. Tissue was sent for routine mycobacterial and fungal cultures. Routine blood work, chest radiograph, and a tuberculin skin test were also performed. At the time of her dermatology visit she described the development of multiple new painful, non-pruritic lesions, bilaterally on the lower extremities. She also reported a red crusted area that appeared at the site of her tuberculin test that was placed subsequent to the development of her lower extremity lesions. Her past medical history was significant for Parkinson's disease, hypothyroidism and hypertension. Her current medications included l-thyroxine, estrogen and diltiazem. Her travel history was only remarkable for a trip to Jamaica the previous spring. She was born and raised in Haiti. She reported a history of a positive tuberculin skin test 20 years ago, but received no therapy. Physical examination revealed a 2 x 3 centimeter firm, nontender left lateral neck mass (Fig. 1). Her right forearm revealed an erythematous, ulcerated, indurated plaque 1.5 cm in diameter (Fig. 2.). Her lower extremities revealed tender 0.5 to 1 cm erythematous nodules below the knees bilaterally (Fig. 3). A punch biopsy of a lower extremity nodule revealed a mild pervisacular dermal infiltrate. Within the subcutaneous tissue there was septal widening. There was also a lymphohistiocytic infiltrate with a slight admixture of neutrophils within the septa of the fat lobules. There was no evidence of necrotizing vasculitis or collagen necrosis. An acid-fast stain was not performed. The histologic findings were consistent with a diagnosis of erythema nodosum. Her laboratory evaluation including CBC, electrolytes, thyroid studies, angiotensin converting enzyme level and chest radiograph were normal. Approximately 1 week after her dermatological evaluation, the fine-needle aspirate culture grew Mycobacterium tuberculosis. A diagnosis of tuberculous lymphadenitis associated with erythema nodosum was confirmed. The patient was started on quadruple therapy of isoniazid, rifampin, ethambutol and pyrazinamide. Her lower limb skins lesions rapidly resolved over the subsequent month and her neck mass also diminished in size. She completed 6 months of antituberculous therapy with complete resolution of her lymphadenopathy.

Percutaneous stenting of the pulmonary arteries (PAs) represents a potential option in cases of PA compression due to a variety of conditions. We present the first reported case of successful bilateral percutaneous stenting of the PAs in a patient with non-small cell lung cancer and severe right ventricular hypertension due to mediastinal lymphadenopathy compressing both PAs. Although the natural course of the disease was not altered, the patient had significant symptomatic relief without adverse effects. Additionally, there was objective evidence of improvement. This case suggests that endovascular stenting is a feasible palliative management option in patients with right ventricular failure due to malignant extrinsic compression of the PAs.

Retroperitonela lymph node dissection (RPLND), cisplatin-based chemotherapy, and tumor surveillance has dramatically improved survival of patients with non-seminomatous germ cell tumors. Complications, including renal vascular injuries, have been encountered with post-chemotherapy RPLND. We report on a patient with delayed renovascular hypertension and nephritic sediment following RPLND. A thirty year old man presented with well-controlled hypertension following treatment of a left testicular non-seminomatous germ cell tumor 11 years earlier. Post-orchiectomy investigation revealed retroperitoneal lymphadenopathy which was treated with cispaltin-based chemotherapy. A residual mass was managed surgically and during perihilar dissection, the left renal vein was injured and repaired. Current investigation revealed hypertension and a nephritic urine sediment, both of which resolved with left simple nephrectomy. We believe that inadvertent renal artery injury was responsible for this late complication.

Out of 334 children with acute lymphoblastic leukemia who were treated with St Jude Total XI and Total XIII chemotherapy protocols were investigated and 21 (6.3%) were hypertensive. The incidence of tumor lysis syndrome was higher in the hypertensive group than in the nonhypertensive group (28.6% vs. 11.5%) (P = 0.035). There were no differences between patients treated with high-dose methylprednisolone and prednisolone St Jude Total XI and Total XIII, St Jude Total XIII LR and St Jude Total XIII HR groups in respect of the above-mentioned parameters. Central nervous system involvement, skeletal system involvement, abdominal lymphadenopathy, elevated lactate dehydrogenase and leukocyte count, French-American-British types and immunophenotypes were not found to be statistically significant to the development of hypertension (P > 0.05). We found that renal leukemic infiltration is a risk factor in hypertension development (P = 0.04) and hypertension is a risk factor for renal parenchymal disorder in the follow-up period (P = 0.0001). Six patients presenting with hypertension in the first week of disease therapy were evaluated for renal parenchymal disorder and glomerular filtration rate abnormality in the follow-up period. Glomerular filtration rate abnormality was found in 1 and renal scintigraphic dimercaptosuccinic acid abnormalities (reduced uptake and dilated hypoactivity) were found in 4 patients. Hypertension was also found to be a risk factor for renal parenchymal disorder in the follow-up period.
