11/1021. Septic shock due to helicobacter fennelliae in a non-human immunodeficiency virus-infected heterosexual patient. helicobacter fennelliae (formerly campylobacter fennelliae) has been reported to cause bacteremia in homosexual men with or without human immunodeficiency virus (hiv) infection. We report here a 48-year-old, non-hiv-infected, heterosexual man with diabetes mellitus and cirrhosis of the liver who developed bacteremia and septic shock due to H. fennelliae. The patient was treated successfully initially with intravenous ampicillin-sulbactam and ceftazidime, followed by ampicillin-sulbactam only. These agents were active in vitro against the isolate by E-test results. To our knowledge, this is the first documented case of septic shock due to H. fennelliae in a non-hiv-infected, heterosexual, immunocompromised patient. ( info) |
12/1021. insulin resistance in patients with depression and its changes in the clinical course of depression: a report on three cases using the minimal model analysis. It has been reported that depression and diabetes mellitus often occur together, and insulin resistance has been observed in patients with depression. For further understanding of the relationship of depression to insulin resistance, three patients with depression were given the oral glucose tolerance test (OGTT) and the frequently sampled intravenous glucose tolerance test (FSIGT) with minimal model analysis before and after antidepressant treatment. Depressive patients showed decreased glucose tolerance, enhanced insulin secretion, and diminished insulin sensitively during OGTT and FSIGT. These abnormalities were resolved after their recovery from depression without changes in body weight or diet. ( info) |
13/1021. Cyclosporin A mono-therapy in nephrotic syndrome with contra-indication of steroid therapy. We describe three cases of nephrotic syndrome with a contra-indication for steroid therapy successfully treated with cyclosporin A (CsA). A 21-year-old man with focal segmental glomerulosclerosis (FSGS) complicated by necrosis of the femoral head, and a 34-year-old woman and a 48-year-old man with minimal change disease (MCD) complicated by psychogenic reaction and diabetes mellitus, respectively, were given CsA at initial dosages of 3.8-5.0 mg/kg/day and immediately remitted completely. However, two of these patients suffered relapses when CsA was tapered. They are currently maintained in complete or partial remission on CsA at dosages of 3.2-4.7 mg/kg/day. These findings suggest that CsA mono-therapy may be useful in nephrotic syndrome patients contra-indicated for steroid therapy. ( info) |
14/1021. Neurological deficit following spinal anaesthesia: MRI and CT evidence of spinal cord gas embolism. A 62-year-old diabetic woman developed permanent neurological deficits in the legs following spinal anaesthesia. MRI showed oedema in the spinal cord and a small intramedullary focus of signal void at the T10 level, with negative density at CT. Intramedullary gas bubbles have not been reported previously among the possible neurological complications of spinal anaesthesia; a combined ischaemic/embolic mechanism is hypothesised. ( info) |
| We report a family in which a mother and son were affected with diabetes mellitus and myopathy characterized by ragged red fibers and suggestive of mitochondrial disease. Mitochondrial dna (mtDNA) analysis of dna isolated from peripheral blood showed a T-->C point mutation at nucleotide position 14709, in the transfer rna gene for glutamic acid. We review the association of diabetes and mtDNA mutations. This child's case is unusual because of the early onset of diabetes, which is more typical of mtDNA deletions. ( info) |
16/1021. mucormycosis of the central airways: CT findings in three patients. Computed tomographic (CT) findings are described in three diabetic patients with central airways mucormycosis. The CT findings of the tracheobronchial mucormycosis include enhancing areas of mural thickening (n = 3), luminal narrowing (n = 3), intramural air (n = 3), low-attenuation nonenhancing bronchial wall thickening (n = 2), and bronchonodal fistula formation (n = 1). These CT features in a diabetic patient should raise a high index of suspicion for tracheobronchial mucormycosis, particularly when typical radiographic features of pulmonary tuberculosis are absent.

| Heteroplasmic mitochondrial dna (mtDNA) defects are an important cause of inherited human disease. On a cellular level, the percentage of mutant mtDNA is the principal factor behind the expression of the genetic defect. Marked variation in the level of mutant mtDNA among tissues is thought to be responsible for the diverse clinical phenotypes associated with the same pathogenic mtDNA mutation. This study was designed to determine whether the percentage level of a pathogenic mtDNA molecule is determined by a purely random process. The tissue distribution of the A3243G MELAS point mutation was analyzed in five individuals who were members of a family with maternally inherited diabetes and deafness. The level of mutant mtDNA was measured in four tissues in three individuals and three tissues in two individuals. The highest level of mutant mtDNA occurred in skeletal muscle, followed by hair follicles, and then buccal mucosa, with the lowest levels in blood (leucocyte/platelet fraction). The probability of observing any strict hierarchy in family is 4.82 x 10(-5). These results indicate that the distribution of the A3243G mutation is not solely determined by random processes.

18/1021. Concha bullosa pyocele--undiagnosed for 3 years. We report a rare case of post-traumatic concha bullosa pyocele in a diabetic teenager that has gone undiagnosed for 3 years. The clinical findings, radiological features and management are discussed. The literature is reviewed. ( info) |
19/1021. A case of acromegaly accompanied by adrenal preclinical Cushing's syndrome. We encountered a 58-year-old woman with acromegaly accompanied by a cortisol-secreting adrenal tumor without clinical features of hypercortisolism. The simultaneous occurrence of these two endocrinopathies in one individual is extremely rare. She was diagnosed as having diabetes mellitus 8 years ago. Afterwards, in spite of insulin therapy, her hyperglycemia could not be well controlled. Her acromegaly and preclinical Cushing's syndrome were histopathologically proven to be due to a pituitary adenoma and an adrenocortical adenoma, respectively. Successful treatment for these endocrinopathies resulted in greatly improved blood sugar control because of a reduction in insulin resistance. In this case of preclinical Cushing's syndrome, replacement therapy with glucocorticoid was able to be discontinued at only 8 weeks after adrenalectomy, so that the period of necessary replacement was much shorter than that for overt Cushing's syndrome. This is the first report describing insulin resistance before and after treatment in a case of acromegaly accompanied by adrenal preclinical Cushing's syndrome. ( info) |
| We report a rare case of acromegaly in which pituitary infarction possibly developed in a GH-producing pituitary adenoma following gastrointestinal bleeding from peptic ulcer. In this case, pituitary infarction resulted in spontaneous remission of acromegaly associated with diabetes mellitus. In addition, detailed histological investigation revealed that clinically silent pituitary apoplexy was mainly an acute ischemic event which occurred recently in a GH-producing adenoma. This event led to massive coagulation necrosis of the tumor and endocrinological improvement. ( info) |
