| The authors report a case of a salivary duct carcinoma (SDC) of the parotid gland revealed by a facial palsy. The clinical and pathological features of this highly malignant neoplasm are described. The aggressive nature of this form demands a combined chemo-radio-surgical treatment; only early recognition and treatment are likely to result in a favourable outcome. ( info) |
| We present two cases of Bell's palsy, and another with tinnitus, all in association with pre-eclampsia in the third trimester of pregnancy. We also systematically reviewed the published literature on both Bell's palsy and tinnitus in pregnancy and the puerperium using medline from January 1966 to October 1998, and searched through the references from review articles and original research publications for further studies. Studies were limited to those published in the English language. We then pooled the rates of occurrence for Bell's palsy according to trimester of pregnancy, and postpartum, as well as the associated prevalence of pre-eclampsia or gestational hypertension. We found that the majority of cases of Bell's palsy arose during the third trimester (pooled event rate 71.1%, 95% confidence interval (CI) 64.1-77.2), while almost none arose in the first trimester. During the postpartum period, the distribution of Bell's palsy was 21.3% (95% CI 15.7-28.1) of all cases, with the majority arising within days of delivery. Gestational hypertension or pre-eclampsia was present in 22.2% of cases (95% CI 12.5-36.4), well above the 5% rate in the general population. Only one paper provided data on tinnitus in pregnancy, with the distribution equal across all three trimesters. When compared to non-pregnant controls, the odds ratio for the development of tinnitus during pregnancy was 2.8 (95% CI 1.0-8.1). In conclusion, Bell's palsy, and perhaps, tinnitus, occur more frequently during the third trimester of pregnancy. Both may be presenting prodromal signs of underlying early pre-eclampsia. The pathophysiologic mechanism relating these two entities to pre-eclampsia is also discussed. ( info) |
3/51. Bell's palsy in an older patient with uncontrolled hypertension due to medication nonadherence. OBJECTIVE: To describe and inform pharmacists of a rarely reported occurrence of facial palsy in an elderly patient with uncontrolled hypertension resulting from nonadherence to blood pressure medications. CASE SUMMARY: A 62-year-old Hispanic woman presented to the hypertension clinic with left facial weakness, mild eyelid lag, and auricular pain for two days. The patient self-discontinued fosinopril and minoxidil six days and two days prior to developing these symptoms, respectively. A diagnosis of idiopathic peripheral VII cranial nerve lesion was made after ruling out other possible causes. Corticosteroids were not initiated because of this patient's labile hypertension. Palliative therapy was initiated and the left facial paralysis continuously improved during the six months after discharge. DISCUSSION: patients have rarely presented with facial paralysis as the initial feature of severe hypertension. The relationship between facial paralysis and hypertension has been reported in a small number of cases, including several reports of recurrence of paralysis during acute exacerbations of hypertension. A variety of physiologic theories to explain the relationship between facial paralysis and hypertension have been published, including small hemorrhages into the facial canal which have been confirmed by two autopsies. However, the true etiology remains unknown. CONCLUSIONS: The possible relationship between facial paralysis and uncontrolled hypertension has not been reported in pharmacy literature and has been reported only twice in subspecialty medical journals since 1990. pharmacists should be aware of the complications of hypertension and should question patients about signs and symptoms at each visit. While Bell's palsy complicating hypertension does not appear to be a serious complication, pharmacists must appreciate that the patient should be immediately evaluated to rule out a more serious neurologic event.

| The occurrence of lyme disease is rising steadily in the united states. The majority of health care providers are unfamiliar with this complex syndrome. nurses lack accurate clinical information to provide comprehensive nursing care to these patients. The progression of lyme disease is addressed through three stages. Untreated or poorly managed, lyme disease may become a chronic, debilitating illness. The author's personal story is interwoven and serves to highlight the pathophysiology of the disease and the emotional and physical costs to the patient. ( info) |
5/51. Vagal and hypoglossal Bell's palsy. A 7-year-old boy was referred because of a sudden change to nasal speech, dysarthria for words with explosive consonants in speech, and nasal regurgitation of fluids. The symptoms arose over 1 week following a capricious episode of acute asthmatic bronchitis. Physical and neurologic examinations were normal except for a left deviation of the uvula, accompanied by a "curtain" movement of the posterior pharyngeal wall against the opposite side, and a left deviation of the protruded tongue. No vascular, traumatic, infectious, neoplastic, or neurologic causes could be identified. No therapy was administered. Full recovery occurred 4 months later. The diagnosis was idiopathic vagal and right hypoglossal nerve palsy (Bell's palsy). ( info) |
6/51. Oculostapedial synkinesis following Bell's palsy. A case of oculostapedial synkinesis occurring after Bell's palsy is described. This rare phenomenon has not previously been reported following Bell's palsy. The authors discuss the method of objectively proving the diagnosis, which can be difficult. The patient was successfully treated by stapedius tendon section under local anaesthesia. ( info) |
7/51. Bell's palsy during interferon therapy for chronic hepatitis c infection in patients with haemorrhagic disorders. Two adult patients with life-long severe haemorrhagic disorders commenced on interferon-alpha2b therapy for chronic hepatitis c infection. Both developed Bell's palsy several weeks after commencing therapy, They were started on steroids and, in addition, the first patient discontinued interferon-alpha2b therapy while the second patient elected to continue with therapy. In both cases facial paralysis improved over the ensuing weeks. Bell's palsy is often idiopathic but has been reported. in association with herpesviruses. It is not a recognised complication of chronic hepatitis b or C infection, or interferon-alpha2b therapy. However, the interferons are associated with numerous adverse reactions including various neuropsychiatric manifestations and neurological syndromes. There are several reports of nerve palsies, including optic tract neuropathy, occurring during interferon therapy, and immune-based mechanisms are thought to play a role in the aetiopathogenesis. No reports of Bell's palsy in association with interferon therapy were identified in our literature search, although one possible case has been reported to the Committee of safety in medicine. Although Bell's palsy in our patients may have occurred by chance, a neuropathic effect of interferon-alpha2b on the facial nerve cannot be excluded and we urge physicians using interferons to be aware of this potential side-effect.

8/51. Bell's palsy: a 10-year experience with antiphlogistic-rheologic infusion therapy. OBJECTIVE: Treatment of idiopathic peripheral facial paralysis has remained controversial in many aspects. The authors report their experience with a protocol based on high-dose prednisolone with intravenous low-molecular-weight dextran and pentoxifylline. For this regimen, the term antiphlogistic-rheologic infusion therapy (ARIT) has been coined. STUDY DESIGN: Retrospective case-series review. SETTING: University-based hospital of otorhinolaryngology/head and neck surgery. patients: 334 patients suffering from sudden facial paralysis of unknown cause. INTERVENTION: Treatment consisted uniformly of prednisolone in a starting dosage of 250 mg tapering over 18 days and accompanying infusion of dextran and pentoxifylline. MAIN OUTCOME MEASURES: facial nerve function after 6 months, adverse effects of therapy and comorbidity. RESULTS: From 239 patients with nonrecurrent palsy having received treatment within 12 days after onset, 92% recovered completely (House-Brackmann [HB] Grade I) without sequelae. In incomplete palsy (HB Grade II-V), normal facial function was restored in 97% of cases. Results were significantly better in the group in which therapy had been started within 3 days after the onset of palsy. Other factors such as old age, hypertension, or diabetes did not seem to influence the functional outcome in this series. Serious adverse effects requiring termination of therapy were observed in 1.2% of cases. CONCLUSION: ARIT for Bell's palsy is safe and leads to recovery rates superior to the most optimistic observations of the natural course. ( info) |
9/51. Palatal necrosis in an AIDS patient: a case of mucormycosis. We report a case of rhinocerebral mucormycosis presenting in a patient with AIDS and review the literature on mucormycosis occurring in the setting of hiv disease. mucormycosis in hiv is rare. However, it can be the presenting opportunistic infection in AIDS. Predisposing factors for Mucor infection in hiv disease include low CD4 count, neutropenia, and active intravenous drug use. mucormycosis can present in the basal ganglia, the skin, the gastrointestinal tract, the respiratory tract, or may be disseminated. The disease may develop insidiously or may progress rapidly with a fulminant course. Therapy usually consists of surgical debridement/excision accompanied by intravenous amphotericin b. ( info) |
10/51. facial nerve palsy following intra-oral surgery performed with local anaesthesia. The precise cause of Bell's palsy remains unclear. A variety of mechanisms have been linked to this palsy, including viral re-activation, demyelination, oedema, vasopasm and trauma. A link with dental treatment has been suggested previously, and a series of seven cases of facial nerve palsy following intra-oral surgery are reported. All of the patients had local anaesthetic solution containing adrenaline as the vasoconstrictor administered. There may be under-reporting of this association, as patients with facial nerve palsy are treated by specialists from several disciplines, not only maxillofacial surgeons. An association with local anaesthesia administered to permit dental treatment would have important medicolegal consequences, and perhaps go some way to explaining the pathophysiology of Bell's palsy.
