2/14. Reversible ageusia after chemotherapy with pegylated liposomal doxorubicin.OBJECTIVE: To report a case of reversible ageusia in a patient with multiple myeloma receiving pegylated liposomal doxorubicin. CASE SUMMARY: A 67-year-old man with a history of arterial hypertension and persisting left bundle-branch block was diagnosed with multiple myeloma. He was initially treated with cyclophosphamide 200 mg/m(2) (days 1-4), pegylated liposomal doxorubicin 20 mg/m(2) (day 1), and dexamethasone 40 mg (days 1-4) (CLAD). That treatment was followed by high-dose melphalan therapy and autologous peripheral stem-cell transplantation. The disease recurred 18 months later, and renal failure developed. The patient was again treated with the CLAD protocol. After the first cycle, almost complete ageusia occurred, along with weight loss and severe depression. Chemotherapy was continued, but pegylated liposomal doxorubicin was replaced by conventional doxorubicin. Within 12 weeks, the patient's sense of taste returned to normal. DISCUSSION: Pegylated liposomal anthracyclines are increasingly being used as a less cardiotoxic alternative to conventional doxorubicin in first- and second-line therapy of multiple myeloma. Whereas cardiotoxicity and unspecific reactions are seen less frequently, palmar-plantar erythrodysesthesia is a common reaction to pegylated liposomal anthracyclines. No other reasons for ageusia in our patient could be identified. Based on the Naranjo probability scale, ageusia was rated as a probable reaction to pegylated liposomal doxorubicin. CONCLUSIONS: As with all new and innovative drugs, thorough documentation of infrequent adverse events is necessary. We would like to raise awareness for ageusia, which appears to be a rare but severely impairing adverse reaction to a relatively new pharmacologic agent.- - - - - - - - - - ranking = 1keywords = taste (Clic here for more details about this article) |
3/14. Hypogeusia as a complication of uvulopalatopharyngoplasty and use of taste strips as a practical tool for quantifying hypogeusia.Hypogeusia is an uncommon complication of uvulopalatopharyngoplasty (UPPP) and few reports in the literature have documented it. Excision of part of the soft palate and damage to the glossopharyngeal nerve or its lingual branch as a result of diathermy or surgery are the possible causes. The case of a 45-year-old male who suffered hypogeusia following UPPP is reported herein. He reported no improvement over a 6-month period. Quantitative assessment of his taste threshold for the 4 basic tastes using taste strips showed a score of 7/18, indicating hypogeusia. The possibility of taste disorder as a postoperative complication should be discussed before patients consent to UPPP Postoperative taste threshold assessment should be done using taste strips if the patient complains of taste disorders.- - - - - - - - - - ranking = 11keywords = taste (Clic here for more details about this article) |
4/14. Rare first symptoms of multiple sclerosis.The most frequent first symptoms of multiple sclerosis are the following: sensory symptoms, optic neuritis, motor and cerebellar syndromes. Three female patients have been diagnosed with multiple sclerosis on the basis of Poser's criteria. The onset of the disease was manifested in these cases with non-typical and rare symptoms. Patient 1, a woman, aged 24. The first symptom of the disease was an isolated lesion of nerve VI on the right side. Patient 2, a women, aged 30. The first symptom of the disease was acute pain localised within the area of the lumbar-sacral spine. Patient 3, a woman, aged 43. The first symptom of the disease was loss of taste and smell.- - - - - - - - - - ranking = 1keywords = taste (Clic here for more details about this article) |
5/14. Transient hemiageusia in cerebrovascular lateral pontine lesions.knowledge of human central taste pathways is largely based on textbook (anatomical dissections) and animal (electrophysiology in vivo) data. It is only recently that further functional insight into human central gustatory pathways has been achieved. magnetic resonance imaging studies, especially selective imaging of vascular, tumoral, or inflammatory lesions in humans has made this possible. However, some questions remain, particularly regarding the exact crossing site of human gustatory afferences. We present a patient with a pontine stroke after a vertebral artery thrombosis. The patient had infarctions in areas supplied by the anterior inferior cerebellar artery and showed vertical diplopia, right sided deafness, right facial palsy, and transient hemiageusia. A review of the sparse literature of central taste disorders and food preference changes after strokes with a focus on hemiageusia cases is provided. This case offers new evidence suggesting that the central gustatory pathway in humans runs ipsilaterally within the pons and crosses at a higher, probably midbrain level. In patients with central lesions, little attention has been given to taste disorders. They may often go unnoticed by the physician and/or the patient. Central lesions involving taste pathways seem to generate perceptions of quantitative taste disorders (hemiageusia or hypogeusia), in contrast to peripheral gustatory lesions that are hardly recognised as quantitative but sometimes as qualitative (dysgeusia) taste disorders by patients.- - - - - - - - - - ranking = 6keywords = taste (Clic here for more details about this article) |
6/14. An unusual presentation of chronic graft-versus-host disease in an unrelated bone marrow transplantation.The case described is that of an unrelated bone marrow transplantation in a 43-year-old man. Although the major histocompatibility complex met the criteria for a perfect genotypic match, de novo graft-versus-host disease developed with unusual manifestations involving structures of the oral cavity and associated areas. The loss of taste and smell, as well as profound xerostomia, was treated by stimulating salivary flow. Synergistic sialagogues were used with the hope that an increase in salivary production would mediate an improvement in taste and smell.- - - - - - - - - - ranking = 2keywords = taste (Clic here for more details about this article) |

8/14. Persistent high-altitude headache and aguesia without anosmia.High-altitude headache and taste dysfunction are usually cured within a few months by descent to sea level. We studied a patient who had persistent bitemporal throbbing headache with the associated findings of high-altitude headache syndrome 15 years after a compression chamber accident. He also had loss of taste without loss of smell since the incident.- - - - - - - - - - ranking = 2keywords = taste (Clic here for more details about this article) |

Hemiageusia, hemianaesthesia and hemiatrophy of the tongue.A patient with a submandibular gland carcinoma was found clinically to have a unilateral chorda tympani, lingual and hypoglossal nerve deficit. This unique neurological entity of loss of taste sensation of one-half of the tongue (hemiageusia), hemianaesthesia and hemiatrophy of the tongue, has not previously been reported.- - - - - - - - - - ranking = 1keywords = taste (Clic here for more details about this article) |
10/14. Generalized argyrosis in man: neurotological, ultrastructural and X-ray microanalytical findings.Generalized argyrosis can produce a number of abnormalities, including skin discoloration, liver and kidney dysfunction. We describe a patient with generalized argyrosis following long-term self-treatment with oral silver intake, in whom skin discoloration, progressive taste and smell disorders, vertigo and hypesthesia were observed. These findings were confirmed by chemosensory tests and electrophysiological investigations. The development of hypogeusia was assessed by subjective tests, while the progression of hyposmia was followed by recording olfactory evoked cortical potentials. light and electron microscopy of tissue samplings demonstrated electron-dense mineral deposits in basal membranes, in macrophages, in the perineurium of peripheral nerves, along elastic and collagenous fibers, and in necrotic cells of the oral submucosa. silver and sulfur deposits in affected tissues could be defined by X-ray microanalysis. The quantitative ratio between silver and sulfur in involved tissues was similar to that of an inorganic silver-sulfide (Ag2S) standard. The minute increase in the sulfur content when compared to the inorganic standard suggested a sulfur containing organic matrix of the tissue precipitates. Our findings indicate that the affinity of silver for membrane and neuronal structures and the deposition of silver as an insoluble compound (Ag2S) induce the progression of clinical disease.- - - - - - - - - - ranking = 1keywords = taste (Clic here for more details about this article) |
