Gorham's disease: a literature review and case reports

Gorham's disease (disappearing bone disease, massive osteolysis, idiopathic osteolysis, essential osteolysis, progressive atrophy of bone, spontaneous absorption of bone, phantom bone, hemangiomatosis/lymphangiomatosis of bone, progressive osteolysis) is an extremely rare occurrence. There are fewer than 150 reported cases in the literature. This disorder can be characterized by spontaneous or posttraumatic progressive resorption of bone. The etiology is still very speculative, the prognosis unpredictable, and any effective therapy still unknown. This paper presents a review of the literature and two case reports of suspected Gorham's disease of the bones of the foot.     

Vibrio vulnificus infections: case reports and literature review

This study's purpose was to determine the validity of near-infrared interactance (NIR) and bioelectric impedance (BIA) in tracking changes in body composition over 12 wk of either a high intensity endurance (ET) or resistance (RT) training program in nondieting weight-stable untrained males. Prior to and following the control or training period, each subject completed a series of body composition analyses including hydrostatic weighing (HW) with a measurement of residual volume: anthropometric measurements including height, weight, skinfold, and girth: BIA measurement: and NIR measurements. Based on the HW results, there were no significant body composition changes in the control group. For the ET group, a significant decline in relative body fat resulted from a reduction in fat weight (FW) with no change in fat-free weight (FFW). In the RT group, both a significant decline in FW and an increase in FFW contributed to this group's decline in relative body fat. Tracking changes in relative body fat, FW, and FFW, skinfolds agree reasonably well with HW in all groups while BIA and NIR did not always track body composition changes well. For example, SF and BIA were significantly correlated with the changes in FFW (HW = +4.1%, SF = +4.5%. BIA = +3.1%. NIR = -0.7%) observed in the RT group compared to HW (SF: r-value = 0.45, SEE = 2.5; BIA: r = 0.33, SEE = 3.4) while the NIR measurements were nonsignificant (r = 0.09, SEE = 5.0). Interestingly, NIR underestimated the gain in FFW in the resistance trained group while BIA underestimated the changes in relative body fat. FW, and FFW in the endurance trained group. Based on these results, BIA and NIR appear not to be appropriate measurement tools for tracking body composition changes in endurance and resistance training individuals respectively.     

Adult-onset subacute sclerosing panencephalitis: case reports and review of the literature

Temperature was measured during drilling in bovine cortical bone specimens. A surgical drill fitted with a custom-designed speedometer and mounted on a drill press was used to drill holes at one speed, 49,000 rpm, and at forces in the range of 1.5 to 9.0 N. The resulting temperatures were recorded by thermocouples placed at various locations. The distribution of maximum local temperature rise (delta T) was best fitted by the function delta T = aR-b, where R is the distance from the center of the drilled hole and a and b are constants that were found by regression analysis. It was also found that the temperature increased with force, up to about 4.0 N, and then decreased at forces greater than that because of decreased drilling time. A separate series of tests revealed that temperatures were higher in the longitudinal direction than in the circumferential direction; this difference was attributed to the anisotropic thermal properties of bone.     

Interhemispheric subdural hematoma in adults: case reports and a review of the literature

The interhemispheric subdural hematoma is a relatively uncommon type of subdural hematoma, especially seen in patients with blood clotting disturbances. When its mass becomes sufficiently large, specific neurological abnormalities such as hemiparesis and signs of the falx syndrome are seen. Treatment can consist of conservative observation or craniotomy and is dictated by the clinical course. Conservative management is the treatment of choice for patients without disturbances of consciousness and for patients with stable clinical conditions. Surgical treatment is necessary in patients with progressive deterioration. Three case reports are presented, as well as a review of 64 cases described in the literature. The salient aspects of this clinical entity are discussed.     

Droperidol in the interim management of severe mania: case reports and literature review

There is little information in the literature concerning the use of droperidol in psychiatry. This article presents three cases in which extremely agitated and treatment-refractory persons with mixed mania derived benefit from droperidol administered orally. Symptomatic improvement, including decreased agitation and intrusiveness, improved sleep, and decreased rates of sleep, was observed with the use of oral droperidol at doses ranging from 10-80 mg daily. The only adverse reaction was a dystonia in one patient. This article also reviews the limited available literature on the use of droperidol in psychiatry. Only eight English language articles describing the use of droperidol for psychosis or agitation were found. Future controlled studies to examine the usefulness of oral dosing of droperidol in mania are suggested.     

Intraduodenal hematoma complicating intestinal biopsy: case reports and review of the literature

We report two cases of postbiopsy duodenal hematoma and review 14 additional cases. Duodenal hematoma predominantly occurs in children and presents with abdominal pain, vomiting, and pancreatitis. Upper gastrointestinal series, abdominal ultrasound, and CT scan are useful in visualizing the hematoma. No comparative studies of the usefulness of these techniques are available, but a CT is indicated if perforation is suspected. The treatment is conservative if no perforation is detected, and resolution of symptoms generally occurs within 2 wk.     

Reflex sympathetic dystrophy in hemiplegia--two case reports and review of the literature

Reflex sympathetic dystrophy (RSD) can be precipitated by a variety of events. We report two cases of RSD in hemiplegic patients detected within three months of the cerebrovascular accidents. Diagnosis of RSD was based upon clinical and scintigraphic findings. Management included elevation, range of movement of the affected joints and analgesics. With treatment, the pain and swelling subsided, range of motion of joints improved and the patients were able to participate in the rehabilitation programme. A high index of suspicion, early diagnosis and aggressive treatment were found to be essential for the successful treatment of RSD.     

Calcification of the fetal heart--four case reports and a literature review

Calcification of the heart and vessels in fetuses is a rare condition. It may be dystrophic or metastatic. An extremely rare form of vascular calcification has been termed 'idiopathic arterial calcification of infancy', which is inherited in an autosomal recessive pattern. We report four cases of myocardial calcifications of different origin diagnosed in utero. The correct diagnosis is very important in regard to genetic counselling.     

Moyamoya disease and pregnancy: case report and review of the literature

OBJECTIVE AND IMPORTANCE: Many female patients with moyamoya disease are of childbearing years, including those who were diagnosed before entering their childbearing years. However, there have been no extensive reviews of the management of pregnancy and delivery in association with moyamoya disease. The purpose of this report is to describe the case of a patient with moyamoya disease complicated by pregnancy and to review the literature on other such cases. CLINICAL PRESENTATION AND INTERVENTION: We report a 23-year-old primipara with moyamoya disease who delivered uneventfully by cesarean section under spinal anesthesia at 38 weeks of gestation. In the literature, 30 cases were reported of patients who had been diagnosed with moyamoya disease before pregnancy and delivery, and 23 patients who were symptomatic and were diagnosed for the first time with moyamoya disease in association with pregnancy. CONCLUSION: There is no evidence that pregnancy increases the risk of cerebrovascular accident or that bypass surgery decreases its risk. Poor prognosis of the patient or the newborn is mostly caused by cerebral hemorrhage and not by cerebral ischemia. It is important to control blood pressure and especially to avoid toxemia during pregnancy. Either cesarean section or vaginal delivery can be accomplished safely. Any anesthetic method can be used, provided special attention is given to avoiding hypocapnia, hypotension, and hypertension. Oral contraceptives should be avoided.     

Mesenteric ischemia secondary to cocaine abuse: case reports and literature review

In summary, we report two cases of mesenteric ischemia following cocaine abuse in young women. In such cases it is always difficult to prove a direct causal relationship between the abuse of cocaine and mesenteric ischemia. Both our patients were relatively young (in their thirties) and did not have any history of atherosclerosis, and their urine toxicity screens were positive for the use of cocaine. Cocaine-related hospital visits are on the increase. Mesenteric ischemia should be considered in the differential diagnosis when evaluating a young patient with a history of cocaine abuse presenting with an acute abdomen.     

Hepatitis associated with terbinafine therapy: three case reports and a review of the literature

Single-rooted premolar teeth, stained with blood utilizing the technique devised by Freccia & Peters (1981), were subjected to traditional and non-peroxide bleaching agents. Colour changes were recorded over a period of 7 days using a Speedmaster R75-CP Reflection Densitometer. The most efficient removal of staining occurred after the application of 30% hydrogen peroxide, with sodium perborate being 75% as effective. All bleaching agents realized their optimum efficacy within the first 3 days. A combination of three enzymes (amylase, lipase and trypsin) with disodium edetate was not as effective as the routine bleaching agents; however, the combination did have a modifying effect on the blood stains. It is suggested that other non-peroxide agents should be investigated to determine their efficacy in removing staining from experimentally induced blood-stained teeth.     

Onychomycosis associated with Onychocola canadensis: ten case reports and a review of the literature

BACKGROUND: Onychocola canadensis is a nondermatophyte mold associated with onychomycosis particularly in temperate climates (eg, Canada, New Zealand, and France). The slow growth rate of O canadensis and lack of resemblance to any other known nail-infecting fungus may have delayed its discovery. We are aware of 23 mycologically confirmed cases of O canadensis in the literature. OBJECTIVE: We describe 10 previously unreported Canadian patients, specimens from whom grew O canadensis. We also review the literature on infections associated with this organism. METHODS: Cases of O canadensis onychomycosis were diagnosed on the basis of (1) the finding of compatible filaments on direct microscopy of nail and (2) consistent culture from repeated specimens. All patients from whom O canadensis was isolated were followed up, but those in whom outgrowth was not consistent were not accepted as having "authentic" infections. RESULTS: In 10 patients O canadensis was found to be associated with distal lateral subungual onychomycosis (6 patients), white superficial onychomycosis (1 patient), and as an insignificant contaminant in the nails of 3 patients. Less commonly the organism may cause tinea manuum or tinea pedis interdigitalis. O canadensis appears to be more frequent in the elderly, especially females. It is not unusual for a patient with onychomycosis caused by O canadensis to be a gardener or farmer, suggesting that the infectious inoculum may originate from the soil. The optimal therapy for onychomycosis caused by this organism remains unclear. CONCLUSION: O canadensis may be the etiologic agent of distal and lateral subungual or white superficial onychomycosis; however, it may sometimes be present in an abnormal-appearing nail as an insignificant finding, not acting as a pathogen.     

Cirrhosis and pregnancy. A case report and review of the literature

A clinical case of a pregnant suffering from hepatic cirrhosis with ascites, splenomegaly and portal hypertension is described. The pregnancy carried on till the 31st week, even though with the repeated use of tocholytic agents. Cesarean section was performed because of the onset of serious jaundice and the decline of general maternal conditions. The infant, who had an Apgar score of 8 at the 1st and 5th minute, died on the 10th day because of accuse haemorrhagic interstitial pneumonitis in premature lungs and hepatopathy associated with widespread jaundice. The mother was discharged on the 25th day of the postpartum period, in light of the net improvement of her general metabolic condition, the sudden regression of the jaundice and the decrease of the cholestasis indices. A review of the literature discussing maternal complications fetal risks, management of pregnancy and delivery and outcome of the newborn are presented.     

Fractures of the lateral process of the talus: two case reports and a comprehensive literature review

Fractures of the lateral process of the talus are frequently overlooked and should be considered in the differential diagnosis of patients with acute and chronic ankle pain. Early diagnosis is emphasized in all series reviewed in the literature to prevent long-term complications. Thorough radiographic evaluation is necessary to determine the need for operative vs. nonoperative management. Small nondisplaced fractures are treated with cast immobilization, whereas large or displaced fractures usually require open reduction and internal fixation. Comminution of fragments may necessitate surgical excision. To achieve the best possible results, a timely diagnosis is required, and it is our belief that early treatment has better overall results.     

Focal segmental glomerulosclerosis in children with acute lymphocytic leukemia: case reports and review of literature

In a randomised double-blind parallel study the gastroduodenal tolerability of 300 mg acetylsalicilic acid daily (ASA, CAS 50-78-2) has been evaluated in the presence of placebo (n = 8), 40 mg pantoprazole (CAS 102625-70-7) daily (8 a.m.) (n = 16) and 300 mg ranitidine (CAS 66357-35-5) daily (8 a.m.) (n = 16) in healthy volunteers using upper GI-endoscopy. The treatment period lasted 14 days, endoscopic controls were performed at entry and repeated at day 14. At entry, the mean endoscopic score averaged 1.0 +/- 0.0 (+/- SEM) in the ASA/placebo, in the ASA/pantoprazole and the ASA/ranitidine group. In the placebo experiments 300 mg ASA daily induced marked gastroduodenal lesions at day 14 (lesion score of 6.8 +/- 1.4 (+/- SEM). Concomitant administration of 40 mg pantoprazole daily offered significant protection against 300 mg ASS daily on day 14 (2.1 +/- 0.6) (+/- SEM) (p < 0.05) vs ASA/placebo. 300 mg ASA plus 300 mg ranitidine daily reduced the damaging score to 4.9 +/- 1.2 (+/- SEM) (n.s. vs ASA/ placebo). Our data suggest that coadministration of 40 mg pantoprazole daily reduces significantly gastroduodenal lesions evoked by 300 mg ASA daily.     

Extracorporeal circulation in pregnancy: report of a case. Update and review of the literature

OBJECTIVE: To investigate the role of platelet activating factor (PAF) in the hypoxic pulmonary hypertension. MATERIAL AND METHODS: Fifteen of 30 male Wistar rats were exposed to hypoxia for 3 weeks, and another 15 rats served as controls. The pulmonary arterial pressure was examined by catheterization. The sections of rat lung were treated by the avidin-biotin-peroxidase complex method to expose the location of PAF. RESULTS: The rats developed pulmonary hypertension and right ventricular hypertrophy after hypoxic exposure. Under the light microscope, PAF is distributed on the vascular and alveolar walls of normal lung, and the content of PAF in the lung of rats with hypoxic pulmonary hypertension are remarkably higher than those of normoxic controls. CONCLUSIONS: PAF plays not only a physiological role in the rat lung, but also a pathophysiologic role in hypoxic pulmonary hypertension.
