1/123. Unaccountable severe hypercalcemia in a patient treated for hypoparathyroidism with dihydrotachysterol.

    This report describes a forty-seven-year-old female patient with a complex medical history. She was suffering from an unspecified interstitial lung disease, papillary thyroid carcinoma which had been treated, hypoparathyroidism after thyroidectomy for which she was receiving dihydrotachysterol and calcium, and atrial fibrillation and congestive heart failure as a result of mitral stenosis. Shortly after mitral valve replacement she developed a severe hypercalcemia (serum calcium 5.95 mmol/l) during a febrile illness. At that time anti-tuberculous agents were also being administered for presumed tuberculosis. The possible mechanisms for this severe elevation of the calcium level are discussed. immobilization, while Paget's bone disease was present, and perhaps enhanced activation of dihydrotachysterol by rifampicin, could have led to increased calcium-release into the circulation. Continuous supplecation of calcium and vitamin d, provoked dehydration and the mechanism of the milk-alkali syndrome also contributed to this extremely high calcium level. It is concluded that hypoparathyroid patients being treated with vitamin d and calcium should be carefully monitored in the case of an intercurrent illness or a change in medication. ( info)

2/123. The surgical significance of the proteus stone.

    62 patients with staghorn calculi who underwent conservative surgery at the Liverpool Regional Urological Centre since 1962 have been reviewed. The evidence shows that stone disease due to proteus is more rapidly progressive than that due to other organisms. Recurrences of proteus stones continue to behave in the same manner. Complete kidney clearance at operation is an essential part of the management of these stones, if renal substance is to be preserved. ( info)

3/123. Preseptal cellulitis secondary to Proteus species: a case report and review.

    BACKGROUND: Preseptal cellulitis is a serious ocular condition that--if left untreated--has the potential to cross the septal barrier, spread to the posterior orbit, and may result in fatal complications. Because it is difficult to determine the pathogen responsible for any cellulitis without aspirating a culture sample, treatment is usually instituted by an assumption of the most common causative organisms, staphylococcus or streptococcus. CASE REPORT: A 42-year-old black woman manifested signs and symptoms consistent with right preseptal cellulitis. Throughout treatment, visual acuity remained 20/20 for both eyes, extraocular muscles were unrestricted without pain, and anterior globe structures were clear. The patient was started on a regimen of 250-mg oral dicloxacillin four times a day. When no response was seen at 36 hours, the patient was changed to 500-mg oral ciprofloxacin every 12 hours. She responded to the 500-mg ciprofloxacin and recovered with no sequelae. An abscess, which had formed during the cellulitis, self expressed and this material was cultured. The cultures identified the responsible organism as Proteus species, an unexpected pathogen in a well-groomed patient. CONCLUSION: This case demonstrates the need to consider alternate pathogens when treating preseptal cellulitis, change medications accordingly, and consider alternate treatments as needed. ( info)

4/123. Nephrobronchial fistula secondary to xantogranulomatous pyelonephritis.

    We report a case of staghorn nephrolithiasis that evolved into xanthogranulomatous pyelonephritis with perinephric abscess, nephrobronchial fistula, and lung abscess. The patient was an intravenous drug abuser who tested positive for human immunodeficiency virus, without evidence of acquired immunodeficiency syndrome. He presented with a 2-month history of untreated repeated episodes of left flank pain and hyperpyrexia. Treatment involved left nephrectomy, debridement of abscess, tube drainage, and intravenous antibiotics. The patient illustrates the need to consider untreated nephrolitiasis as a predisposing factor for pulmonary complications. ( info)

5/123. Diagnostic and therapeutic vitrectomy for endophthalmitis.

    The introduction of a compact portable vitreous suction cutter enables the aspiration and resection of infected ocular tissues for diagnostic and therapeutic purposes. Four cases of postoperative bacterial endophthalmitis are presented in which mechanical anterior vitrectomy was performed in addition to conventional antimicrobial therapy. Three of these eyes were saved and 2 retained the possibility of useful vision. A rationale for the aggressive managements of endophthalmitis is presented. ( info)

6/123. Total excision of the sternum and thoracic pedicle transposition of the greater omentum; useful strategems in managing severe mediastinal infection following open heart surgery.

    Mediastinal sepsis following open heart surgery is a significant cause of death. Open drainage of the mediastinumalone was employed originally in management of this problem. More recently, debridement, drainage, and reclosure have been used. Various irrigation solutions, such as antibiotics and Betadine, have been advocated to control severe mediastinal sepsis. Three principles of management in patients unresponsiveness to the above techniques have proved successful in two patients with life-threatening mediastinal sepsis: (1) radical, complete excision of the sternum and adjacent costal cartilages; (2) transposition of the greater omentum on a vascular pedicle to the mediastinum; and (3) primary closure with full-thickness rotational skin flaps. The radical excision of the sternum removes residual foci of sepsis in cartilage and sternal bone marrow. The transposition of the omentum provides a highly vascular, rapidly granulating covering for the contaminated great vessels and hase been successfully to prevent recurrence of suture line bleeding of an exposed ascending aortic anastomosis site. Primary closure of the wound with full-thickness skin flaps provides a suprisingly satisfactory covering for the heart. Preoperative and postoperative measurements of ventilatory mechanics have shown relatively small ventilatory impairment after the alteration of the thoracic cage imposed by excision of the sternum. Two patients have returned to active lives. A treatment failure probably due to incomplete adherence to these guidelines also is presented. ( info)

7/123. Successful in situ treatment of an infected ascending aortic graft.

    Infection of an ascending aortic prosthesis is a grave complication associated with a high mortality. In most cases, extraanatomic bypass and removal of the infected vascular graft are not possible. Furthermore, the standard approach to this problem, which includes excision and replacement or debridement and repair of infected thoracic aortic grafts, carries a high early mortality. We report the successful treatment of this life-threatening complication using a conservative strategy in which the aortic prosthesis was salvaged by in situ disinfection followed by coverage with tissue flaps.

8/123. Protean infectious types and frequent association with neurosurgical procedures in adult serratia marcescens CNS infections: report of two cases and review of the literature.

    serratia marcescens is a rare pathogen of adult central nervous system (CNS) infection. We report on the clinical features and therapeutic outcomes of two adult patients with such infections. The clinical characteristics of 13 other reported adult cases are also included for analysis. The 15 cases were nine males and six females, aged 19-83 years, in whom, underlying post-neurosurgical states and ear operation were noted in 93% (14/15). fever and conscious disturbance were the most common clinical manifestations of these 15 cases, followed by hydrocephalus, seizures, and wound infections. The manifestation types were protean, including meningitis and focal suppurations such as brain abscess, cranial and spinal epidural abscess, cranial subdural abscess, and infected lumbar pseudomeningocele. One case of S. marcescens CNS infection was diagnosed postmortem; the other 14 were diagnosed by the positive culture from CSF or pus. Antibiotic therapy with or without neurosurgical intervention was the management strategy in 14/15 cases. The therapeutic results showed a high mortality rate. ( info)

9/123. Sonographic detection of multiple brain abscesses in a newborn with iga deficiency.

    We report the case of a neonate with selective iga deficiency and multiple brain abscesses diagnosed with sonography. Brain sonography revealed multiple abscesses in the left hemisphere; the abscesses ranged from 10 to 20 mm. Cultures obtained from the cerebrospinal fluid and blood were positive for proteus mirabilis. The neonate responded promptly to broad-spectrum antibiotic therapy and had no neurologic sequelae. Because iga deficiency is associated with infections, we believe it was a predisposing factor for the brain abscesses. ( info)

10/123. Pyogenic thyroiditis and hiv infection.

    Infective thyroiditis remain rare disease entity. Six patients were seen in Jos, nigeria in the last five years. All of them were hiv positive. The presentation and management of these patients are high-lighted. The clinical features and bacteriology were similar to those previously documented for infective thyroiditis. ( info)
