1/48. Palmar fasciectomy and keloid formation.A 53-year-old Caucasian with keloid formation on the palmar surface of the hand following Dupuytren's contracture release is presented. Only two other cases of keloid formation on the hand have been found in English literature, both on black patients. This is the first known case with association of Dupuytren's disease to be reported. Surgical excision of the keloid with intraoperative injection of triamcinolone of the wound edges resulted in clinical cure.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
2/48. Bilateral recurrent acute retinal pigment epitheliitis.Acute retinal pigment epitheliitis appears to be a specific discrete process of unknown etiology. It is generally unilateral but can be recurrent and can affect both eyes. Eyes in which the disease has run its course exhibit little or no unusual ophthalmoscopic or visual function abnormalities. The actue phase of the disease is localized to the macular area. The lesions are localized in the retinal pigment epithelium as shown by slit-lamp and contact-lens examination, the small lesions more or less surrounding the fovea. They vary from tiny grayish to black spots, which may become surrounded by a lighter halo. Fluroescein angiography is normal in acute phases but the halo-like areas may represent "window defects" with hyperfluorescence in later stages.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
3/48. Demyelinating disorder of the central nervous system occurring in black South Africans.OBJECTIVES: To investigate the nature and cause in eight black South African patients of a recurrent (multiphasic), remitting, and relapsing demyelinating disease of the CNS. methods: The clinical and laboratory investigations and radiological manifestations of these patients were documented. RESULTS: Each patient had two or more acute attacks of demyelinating disease affecting the CNS. The clinical presentations of the patients were predominantly those of multiphasic neuromyelitis optica (NMO). brain MRI in these patients showed features consistent with those described for acute disseminated encephalomyelitis (ADEM), as well as lesions that are described in multiple sclerosis. There was involvement of the corpus callosum in addition to typical ADEM lesions. Laboratory investigations excluded all other known causes of multiphasic CNS demyelination. Oligoclonal antibodies were not detected in these patients at any time. The patients were all from a population with a low risk for MS (black South Africans). CONCLUSION: The patients described here represent a new phenotypic expression of a recurrent (multiphasic), steroid sensitive, inflammatory demyelinating disorder of the CNS occurring in black South Africans. The disorder is either a distinct inflammatory demyelinating disorder of the CNS of as yet unknown aetiology, or a varied form of MS (ADEM/NMO) occurring in a population with a low risk (where the genetic trait and environmental risk factors for MS do not exist) for MS.- - - - - - - - - - ranking = 7keywords = black (Clic here for more details about this article) |
4/48. Infundibulofolliculitis of the neck.Disseminate and recurrent infundibulofolliculitis is an uncommon eruption that typically presents on the trunk and proximal extremities of young black men. A case of a young girl with infundibulofolliculitis limited to the neck is presented and reviewed, and a proposal for renaming it is considered.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
5/48. Spastic eversion of the upper eyelids.A 2-year-old black Nigerian infant presented with eversion of the upper eyelids which followed an episode of presumed measles conjunctivitis. Eversion recurred despite patching and taping, but was terminated by facial akinesia and placement of lid sutures. Orbicularis spasm undoubtedly plays a role in the pathophysiology of this disorder, acting together with other etiologic factors.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
6/48. multiple myeloma associated with lactic acidosis.Type B lactic acidosis is rare among patients with malignant diseases. To date only one case report has documented lactic acidosis occurring in a patient with multiple myeloma (MM). Our patient, a 55-year-old black man, was diagnosed with stage IIIA immunoglobulin g-kappa (IgG-kappa) MM in September 1995. He was found to have severe lactic acidosis at the time of second relapse. During the terminal phase of his disease, he required multiple hospitalizations for management of lactic acidosis and other complications of his MM. No other cause of his elevated lactate levels was identified. Although type B lactic acidosis may more commonly occur in patients with leukemia or lymphoma, it may rarely present in patients with rapidly progressive and refractory MM.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
7/48. Exacerbation of ulcerative colitis by cytomegalovirus infection in an immunocompetent Indian patient.A patient with typical features of idiopathic ulcerative colitis, in remission, developed an attack of severe colitis. sigmoidoscopy showed submucosal black nodules in the sigmoid colon. Mucosal biopsies from the involved areas showed evidence of acute on chronic colitis with cytomegalic cells and intra-nuclear inclusions suggestive of cytomegalovirus (CMV) disease. The patient attained remission following subtotal colectomy and intravenous ganciclovir therapy for 3 weeks. The patient had another relapse five months later. The colonic biopsies during this relapse showed evidence only of idiopathic ulcerative colitis, with no CMV infection. The patient responded well to steroid therapy.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
8/48. aspirin-responsive painful red, blue, black toe, or finger syndrome in polycythemia vera associated with thrombocythemia.Five patients with red, purple blue, or black toes or fingers due to thrombocythemia associated with polycythemia vera (polycythemia and thrombocythemia vera) in four and essential thrombocythemia (thrombocythemia vera) in one are described. The microvascular erythromelalgic syndrome of thrombocythemia was overlooked and progressed to cold blue swollen and painful fingers or black toes in three patients with polycythemia and thrombocythemia vera due to arteriographically documented occlusions of digital or large peripheral arteries with no evidence of preexistent atherosclerotic vascular disease. Concomitant erythromelalgia of the hand palm could be confirmed by the histopathological findings of arteriolar thrombotic lesions in the reticular dermis in two patients with polycythemia and thrombocythemia vera. The increased hematocrit in the presented patients with polycythemia and thrombocythemia vera contributed to the progression of the microvascular syndrome of thrombocythemia to major occlusive ischemic events of the extremities. Standard therapy with oral anticoagulants and reduction of the hematocrit to normal by bloodletting did not affect the platelet-mediated microvascular erythromelalgic, ischemic symptoms in the patients with polycythemia vera because thrombocythemia vera persisted. Complete relief of pain and restoration of the ischemic acral circulation disturbances in patients with thrombocythemia vera or thrombocythemia associated with polycythemia vera in maintained remission by bloodletting could be obtained by long-term treatment with low-dose aspirin.- - - - - - - - - - ranking = 6keywords = black (Clic here for more details about this article) |
9/48. Pigmented fungiform papillae on the tongue in an Asian man.Fungiform papillae of the tongue vary in their appearance. It is not rare for them to be pigmented in black subjects, but this is less common in Asians. We report a case of pigmented fungiform papillae in a 65-year-old Vietnamese man. The patient also had recurrent aphthous ulceration and hepatitis c. pigmentation affected all fungiform papillae and was asymptomatic. Macrocytosis was noted on full blood examination, while liver function tests were normal. The pigmentation of the fungiform papillae remained stable.- - - - - - - - - - ranking = 1keywords = black (Clic here for more details about this article) |
10/48. association between a black band on the inner membrane of a chronic subdural hematoma on T2*-weighted magnetic resonance images and enlargement of the hematoma.OBJECT: The cause and indication for enlargement of chronic subdural hematomas (CSDHs) have remained unresolved. The authors observed a black band on the inner membrane of a CSDH on T2*-weighted magnetic resonance (MR) images obtained in patients with symptoms. After surgical treatment, the band disappeared. The T2*-weighted sequence of MR imaging is an excellent diagnostic tool for detecting ferromagnetic substances, but it is rarely performed in cases of a CSDH. The authors speculate that the black band may be associated with the development of CSDH. methods: To investigate how the black band observed on T2*-weighted MR images contributes to the development of a CSDH, 59 lesions in 50 patients with CSDH (41 men and nine women, mean age 70 /- 11 years [range 48-93 years]) were investigated prospectively. The incidence of black bands on the first T2*-weighted MR image obtained in patients with symptomatic CSDH was 97% (31 of 32 CSDHs), which was significantly higher than that associated with asymptomatic CSDH (11% [three of 27 CSDHs], p < 0.001). The black bands associated with symptomatic CSDH disappeared soon after surgical treatment in 31 CSDHs and became fainter in another. In two instances the CSDH recurred with reappearance of the band. Twenty-four of 27 asymptomatic CSDHs had no accompanying black band. Follow-up MR images demonstrated a later formation of bands in two of 24 asymptomatic CSDHs that enlarged to symptomatic size. Logistic regression analysis revealed that the heterogeneity and thickness of the CSDH on computerized tomography scans were independently and significantly associated with the black band. CONCLUSIONS: The dynamics of the black band may depend on the enlargement or shrinkage of the CSDH.- - - - - - - - - - ranking = 12keywords = black (Clic here for more details about this article) |
