Cotyledonous leiomyoma, a rare variant of uterine leiomyoma: case report

A postmenopausal woman admitted to Bayview Hospital for total abdominal hysterectomy for uterine leiomyoma had unusual frond-like vascular excrescences on the anterior wall. These were biopsied, a subtotal hysterectomy was subsequently performed and cotyledonous leiomyoma, a rare and unusual form of uterine leiomyoma, was diagnosed. The macroscopic and microscopic features were presented.(AU)

Epidemiology of Helicobacter pylori infection in Barbados

The epidemiology of Helicobacter pylori infection in Barbadian patients and controls was studied. H. pylori was isolated from biopsies from 50/100 (50 percent) adult patients undergoing endoscopy for investigation of upper gastrointestinal tract symptoms. Urease was detected in biopsies from 54 patients and gastritis was detected by histology in 71 patients. Serology was performed using a commercial ELISA method. Using an IgG concentration of 10 U/ml as a threshold, antibodies were detected in 78 percent of 100 patients undergoing endoscopy, 72 percent of 230 blood donors and 22 percent of 50 children. The mean antibody concentration was significantly higher in patients (92 U/ml) than in blood donors (49 U/ml) or in children (9.5 U/ml). Culture-positive patients (120 U/ml) had higher IgG concentration than culture-negative patients (64 U/ml). Using isolation of H. pylori or a positive biopsy urease test as a measure of true prevalence of infection, the sensitivity of serology was 96 percent, the specificity 42 percent positive predictive value 67 percent and negative predictive value 90 percent. Seroprevalence increased with age, to a peak of more than 90 percent in blood donors aged 50 - 59 years and in patients aged over 60 years. The epidemiology of H. pylori in Barbados is similar to that in developed countries, where few children was infected, but resembles other developing countries in the high seroprevalence observed in middle-aged adults.

Anterior horn cell degeneration in polymyositis associated with human T lymphotropic virus Type-1 in patients from Barbados

Anterior horn cell degeneration has only ocassionally been noted in patients with tropical spastic paraparesis associated with human T lymphotropic virus type-1 (HTLV-1) infection. We report on three adult patients with HTLV-1-associated polymyositis who had clinical evidence of anterior horn cell degeneration. One patient had moderate proximal weakness and muscle wasting in all four limbs, while two had mild upper limb weakness with more profound proximal weakness and wasting in the lower limbs. In all three patients, elctromyographic findings were compatible with motor unit loss and muscle biopsies showed mononuclear inflammatory cell infiltration; muscle cell biopsies in two patients showed features of denervation. Immunoglobulin G (IgG) antibodies to HTLV-1 were detected by enzyme-linked immunosorbent assay (ELISA) and confirmed by Western immunoblot in serum and cerobrospinal fluid in all three patients. In two, cell cultures were established from peripheral blood lymphocytes and HTLV-1 antigen was identified by immunofluorescence and the ELISA antigen-capture technique using an anti-p19 HTLV-1 mouse monoclonal antibody. The three cases illustrate the variety of neuromuscular disease, other than spastic paraparesis, that may occur in HTLV-1 infection. In some cases of HTLV-1-associated polymyositis, anterior horn cell degeneration may make a significant contribution to the muscle atrophy observed. (AU)

Anterior horn cell degeneration in HTLV-1 associated polymyositis in patients from Barbados - abstract

Anterior horn cell degeneration has only been noted occasionally in patients with tropical spastic paraparesis associated with human T-lymphotropic virus type I infection (HTLV-I). We report on three adult patients with HTLV-I associated polymyositis who had evidence of anterior horn cell degeneration. One patient had moderate proximal weakness in all 4 limbs, while 2 had mild upper limb weakness and profound proximal weakness in the lower limbs. Electromyographic findings indicated motor unit loss. Muscle biopsies in 2 patients showed features of denervation, as well as mono-nuclear inflammatory cell infiltration. HTLV-1 IgG antibodies were detected by enzyme-linked immunosorbent assay, and confirmed by Western-immunoblot, in serum and cerebrospinal fluid in all 3 patients. In two, cell cultures were established from peripheral blood lymphocytes and HTLV-1 antigen was identified by immunofluorescence and the ELISA antigen capture technique, using an anti-p 19 HTLV-1 mouse monoclonal antibody. These 3 cases illustrate the variety of neuromuscular disease, other than spastic paraparesis, that may occur in HTLV-1 infection. Anterior horn cell degeneration may coexist with HTLV-1 associated polymyositis and may make a significant contribution to the muscle atrophy observed in these cases (AU)

Human T-lymphotropic virus type I DNA in spinal cord of tropical spastic paraparesis with concomitant human T-lymphotropic virus type I negative Hodgkin's disease

We studied a 58 year old black women from Barbados who simultaneously developed myelopathy and lymphoma with human T-lymphotropic virus type I (HTLV-I) antibodies in serum and cerebrospinal fluid and died 3 years after onset. Neuropathological examination showed typical tropical spastic paraparesis (TSP). The polymerase chain reaction (PCR) demonstrated defective proviral genome retaining the HTLV-I pX and env regions in thoracic spinal cord, the level most severely affected. Defective HTLV-I in the nervous system retaining the pX region may be relevant to pathogenesis because circulating CD8+ cytotoxic lymphocytes specific for HTLV-I pX occur in HTLV-I myelopathy. This patient's lymph node biopsy specimen was consistent with Hodgkin's disease (HD), nodular sclerosis subtype, of B-cell origin. The PCR in the paraffin-embedded lymph node involved by HD failed to amplify HTLV-I proviral sequences. Complete HTLV-I proviral amplification was obtained in paraffin-embedded lymph node form positive controls (adults T-cells leukemia). To our knowledge the association of TSP and HD has not been reported previously. Despite claims the HD may be associated with HTLV-I, we demonstrated absence of HTLV-I infected T-cell in the lymphoid infiltrate of HD in this case, positive HTLV-I serology notwithstanding.(AU)

Necrotizing haemorrhagic colitis caused by resistant shigella flexneri. Report of a case

A case of fatal infection with shigella flexneri is reported. The 19-year-old male patient who presented with fulminating haemorrhagic colitis died nine days after the onset of symptoms. The infecting strain of shigella flexneri was resistant to multiple antimicrobial agents, including amoxycillin, co-trimoxazole and chloramphenicol (AU)

Uterine leiomyosarcoma with intracerebral metastasis: a case report

A case of a 36-year-old woman with a past history of uterine leiomyosarcoma and an an intracerebral metastasis is reported. The patient presented with a 24-hour history of severe headache with coma, and the CT findings were consistent with a metastatic lesion. Pathological examination of the operative specimen showed features of a leiomyosarcoma. Uterine leiomyosarcoma is an uncommon tumor and metastasis to the brain is rare (AU)

Helicobacter pylori in Barbadian patients undergoing endoscopy - abstract

The prevalence of Helicobacter pylori infection in Barbados was studied in 100 patients undergoing routine endoscopy. Biopsies were taken from within 3 cm of the gastric pylorus for culture, histology and rapid detection of urease in a buffered medium. Fifty-four patients gave a positive urease test, 50 were culture positive and 55 had histological appearance consistent with H. pylori. When compared to culture, the rapid urease test gave a sensitivity of 96 percent and a specificity of 92 percent; the positive predictive value was 92 percent and the negative predicitive value was 96 percent. The prevalence of H. pylori infection in the population studied increased with age, reaching a peak of 70 percent in the 60-79 age group. H. pylori was detected in 95 percent of patients with duodenal ulcers, 83 percent of those with type B. chronic gastritis, 57 percent of those with gastric ulcers and 66 percent of those with carcinoma of the stomach. We conclude that H. pylori infection is common in patients with chronic gastritis and duodenal ulcers in Barbados. We have demonstrated the value of a cheap, rapid direct urease test for the detection of H. pylori in gastric biopsies (AU)

Aspergillosis in a patient with acute lymphoblastic leukaemia

A case is described of a three year old boy with acute lymphoblastic leukaemia (ALL) who presented initially with aspergillosis of the nasophgillosis of the nasopharynx. Fungal infection with Aspergillus species is not uncommon in immunosuppressed children, but this case is noteworthy in that the disease presented at the onset of therapy rather than during the phase of treatment with maximum immunosuppression following chemotherapy. This type of infection is usually associated with the treatment of acute non-lymphoblastic leukaemais (AMS) rather than ALL, and prolonged periods of neutropenia which results from aggressive treatment. This patient responded rapidly to treatment with amphotericin B, coincident with resolution of his neutropenia as the underlying disease was treated, eventually eradicating the fungus (AU)

Childhood malignancies in Barbados (1985-1989): incidence and survival - abstract

The lack of frequency data on childhood malignancies in the Caribbean prompted this 5-year (1985-1989) retrospective study of childhood malignancy in Barbados. Case finding of malignancies in children <15-years-old attending the Queen Elizabeth Hospital, Barbados was undertaken by reviewing medical and other related records for the period of study. Health statistics for the island were obtained from the Statistics Department of the Ministry of Health. There were 44 cases of childhood malignancy of whom 15 died, representing about 0.3 to 1 per cent of all cancer deaths annually. The average annual incidence of childhood cancer for the 5-year-period was 143.5 per million children. Fourteen types of childhood malignancies were found, and the commonest types were brain tumours (27 per cent) and haematological cancers (27 per cent) (AU)
