PMID: 21073040

Fungal infection in the oral cavity is not uncommon. The site involved is usually species related. Cryptococcus rarely infects the oral cavity. We report an elderly patient who presented with a central lesion on the dorsum of the tongue. Biopsy revealed a fungal infection. Special stains confirmed cryptococcus. Being a rare location for cryptococcal infection, clinical suspicion should be correlated with histopathological examination. Once confirmed, the patient should be treated with an antifungal medication.

Ramasamy K, Lim SM, Abu Bakar H, Ismail N, Ismail MS, Ali MF, et al.

Phytother Res, 2010 May;24(5):640-3.

PMID: 19468989 DOI: 10.1002/ptr.2891

Endophytes, which are receiving increasing attention, have been found to be potential sources of bioactive metabolites following the discovery of paclitaxel producing endophytic fungi. In the present study, a total of 348 endophytes were isolated from different parts of 24 Malaysian medicinal plants. Three selected endophytes (HAB10R12, HAB11R3 and HAB21F25) were investigated for their antimicrobial and cytotoxic activities. For antimicrobial activity, HAB10R12 and HAB11R3 were found to be most active against bacteria and fungi, respectively. Their antimicrobial effects were comparable to, if not better than, a number of current commercial antibacterial and antifungal agents. Both HAB10R12 and HAB21F25 were found to be potential anticancer drug candidates, having potent activity against MCF-7 and HCT116 cell lines and warrant further investigation.

In vitro investigation of antifungal activity of allicin alone and in combination with azoles against Candida species

Khodavandi A, Alizadeh F, Aala F, Sekawi Z, Chong PP

Mycopathologia, 2010 Apr;169(4):287-95.

PMID: 19924565 DOI: 10.1007/s11046-009-9251-3

Candidiasis is a term describing infections by yeasts from the genus Candida, and the type of infection encompassed by candidiasis ranges from superficial to systemic. Treatment of such infections often requires antifungals such as the azoles, but increased use of these drugs has led to selection of yeasts with increased resistance to these drugs. In this study, we used allicin, an allyl sulfur derivative of garlic, to demonstrate both its intrinsic antifungal activity and its synergy with the azoles, in the treatment of these yeasts in vitro. In this study, the MIC(50) and MIC(90) of allicin alone against six Candida spp. ranged from 0.05 to 25 microg/ml. However, when allicin was used in combination with fluconazole or ketoconazole, the MICs were decreased in some isolates. Our results demonstrated the existing synergistic effect between allicin and azoles in some of the Candida spp. such as C. albicans, C. glabrata and C. tropicalis, but synergy was not demonstrated in the majority of Candida spp. tested. Nonetheless, In vivo testing needs to be performed to support these findings.

Sangetha S, Zuraini Z, Suryani S, Sasidharan S

Micron, 2009 Jun;40(4):439-43.

PMID: 19261482 DOI: 10.1016/j.micron.2009.01.003

The inhibitory effect of Cassia spectabilis methanol leaf extract was evaluated against biofilm forming Candida albicans, which was sensitive to 6.25 mg/ml concentration of the extract. Transmission (TEM) and scanning electron microscope (SEM) observations were used to study the anticandidal activity and prevention of biofilm formation by the C. spectabilis extract. SEM analysis further revealed reduction in C. albicans biofilm in response to the extract. The main abnormalities noted via TEM study was the alterations in morphology and complete collapse of the yeast cells after 36 h of exposure to the extract. The significant antifungal activity shown by this methanol extract of C. spectabilis suggests its potential against infections caused by C. albicans.

PMID: 23431829

We report a case of Cryptococcus humicolus meningitis complicated by communicating hydrocephalus in an apparently immunocompetent 49-year-old psychiatric patient from a nursing home. He presented with a history of poor oral intake, weight loss, headache, vomiting, blurred vision, frequent falls and unsteady gait for the previous three months. He had a history of chronic cough, productive of whitish sputum for the previous month but no hemoptysis. Cerebrospinal fluid culture was positive for Cryptococcus humicolus. He was treated with intravenous amphotericin B and oral fluconazole and had clinical and microbiological improvement after three weeks of treatment. Unfortunately, the patient acquired nosocomial methicillin-resistant Staphylococcus aureus infection and died due to overwhelming sepsis.

PMID: 15774599

Cryptococcus neoformans is a yeast like fungus, which is commonly found in bird droppings, especially pigeons. Most cases of cryptococcal infections occur in immunocompromised patients or in those who are on long term immunosuppressant therapies. Cryptococcal infection usually presents as a meningoencephalitis or a pulmonary infection. Skin, bone and genital infections are very rare. We report the second case of vaginal cryptococcossis to be reported in English literature and the first to be imaged with CT and MRI.

Chemotype of Litsea cubeba Essential Oil and Its Bioactivity

Abdul Hammid S, Ahmad F

Nat Prod Commun, 2015 Jul;10(7):1301-4.

PMID: 26411035

The essential oils from different parts of Litsea cubeba, collected from the highlands of Sarawak, were isolated and their chemical compositions analyzed. This study demonstrated significant variations in the chemical compositions and the chemical profiles of the volatiles and could provide valuable supplementary information on the geographical variations of the species. The fruit essential oil was dominated by citronellal, d-limonene and citronellol, while the leaf oil was high in eucalyptol and a-terpineol. High concentrations of citronellal and citronellol in both the root and bark oils were identified. In the stem, the oil was dominated by eucalyptol, d-limonene and α-terpineol. The activity of the oils against brine shrimp larvae, bacteria, yeast and fungi was determined. The oils were toxic against brine shrimp larvae with LC50 values ranging from 25.1 - 30.9 μL/mL. The oils also demonstrated a wide spectrum of inhibition against microorganisms with inhibition zones between 19.5 - 46.7 mm against Gram-positive bacteria and 10.5 - 90.0 mm against yeast and fungi. However, the oils were not active against Gram-negative bacteria.

Lachmanan SR, Haniza O, Hisham AN, Subramaniam J, Merican I

Ann Acad Med Singap, 2001 Nov;30(6):656-8.

PMID: 11817299

INTRODUCTION: Bilateral adrenal enlargement is often the result of disseminated malignant disease, and this diagnosis is particularly likely in a patient with severe weight loss. We describe a case with bilateral adrenal enlargement presenting with progressively worsening backache as a prominent symptom.

CLINICAL PICTURE: A 55-year-old man presented with intermittent low back pain which was progressively worsening, fever, anorexia, low back pain and a 10-kg weight loss. He had underlying diabetes mellitus and ischaemic heart disease. He gave a history of travel to caves for worship. Clinically, the most significant findings included nodular lesions in the anterior fauces and left palatoglossal region. Computed tomographic scan revealed bilateral adrenal masses. Biopsies were taken from the palatal nodules, which revealed histiocytes with numerous histoplasma organisms.

TREATMENT: He was commenced on itraconazole 200 mg daily for a period of 9 months. There was a dramatic initial response with settling of his fever and this was followed by subjective improvement in his well-being.

OUTCOME: He is presently on follow-up and has completed 9 months of itraconazole therapy with resolution of all his symptoms and has gained about 10 kg of weight.

Effect of griseofulvin on the toxicity of signal grass (Brachiaria decumbens) in sheep

Haisah AH, Elsheikh HA, Khairi HM, Salam Abdullah A, Rajion MA

Vet Hum Toxicol, 2003 Mar;45(2):68-71.

PMID: 12678289

The effect of griseofulvin treatment on signal grass (Brachlaria decumbens) toxicity was studied in 27 male Wiltshire Indigenous Malaysian crossbred sheep. Grazing on signal grass generally decreased the activity of the drug metabolizing enzymes in livers and kidneys. Griseofulvin oral administration of 5 mg/kg body weight for 5 consecutive days every other week for 10 w increased the hepatic concentration of cytochrome P-450 and the activity of phase II drug metabolizing enzymes (UDP-glucuronyltransferase and glutathione-S-transferase) while it decreased the hepatic and increased the renal activity of phase I enzymes aminopyrine-N-demethylase and aniline-4-hydroxylase. Griseofulvin did not protect sheep against B decumbens toxicity as 5/7 animals treated with griseofulvin and grazed on B decumbens showed signs of the plant toxicity.

Massive pleural effusions in cryptococcal meningitis

Wong CM, Lim KH, Liam CK

Postgrad Med J, 1999 May;75(883):297-8.

PMID: 10533638

Cryptococcal infection uncommonly presents with pulmonary manifestations and even more rarely so as massive bilateral effusions. Pleural involvement is usually associated with underlying pulmonary parenchymal lesions and is unusual while on antifungal therapy. We report a patient with cryptococcal meningitis who, while on intravenous 5-flucytosine and amphotericin B, developed life-threatening bilateral massive pleural effusions with evidence of spontaneous resolution, consistent with prior hypothesis of antigenic stimulation as the cause of pleural involvement.

Fulltext Candida albicans infection of a prosthetic knee replacement: a case report

Badrul B, Ruslan G

Med J Malaysia, 2000 Sep;55 Suppl C:93-6.

PMID: 11200051

We report a 64 year old man who developed Candida albicans infection following total knee arthroplasty. A two-stage exchange arthroplasty was performed after an initial swab culture grew Acinobacter sp. A scanty growth of yeast was also found from the tissue culture. Intravenous cefuroxime was instituted for six weeks followed by reimplantation four months after the removal. Three weeks after that revision, the prosthesis became infected and a culture of knee aspirate established the diagnosis of Candida albicans infection. Treatment consisted of thorough debridement of the involved joint and oral fluconazole for a year. Infection was never totally resolved and a secondary infection with methicillin resistant staphylococcus aureus then developed. Excision arthroplasty was done at two and a half years after the initial infection. At five years follow-up the infection was quiescent and he had a range of movement of 30 degrees to 70 degrees. Knee brace was used to control the valgus-varus stability.

Cryptococcosis at the University Hospital, Kuala Lumpur

Doi SA, Tan CT, Liam CK, Naganathan K

Trop Doct, 1998 Jan;28(1):34-9.

PMID: 9481195

We review our experience with 27 cases of pulmonary and meningeal cryptococcosis at the University Hospital, (Kuala Lumpar, Malaysia) where this is the most common cause of adult meningitis in patients without debilitating illnesses. Of the 27 cases analysed, six presented primarily with pulmonary symptomatology which usually were mainly cough, chest pain and low grade fever. The rest presented with primarily central nervous system (CNS) symptomatology of which headaches and fever were the most consistent symptoms although a third of these patients also had pulmonary lesions noted on chest radiographs. Treatment in all cases was with amphotericin B and 5-fluorocytosine and usually till a total cumulative dose of 1.5 g of amphotericin had been reached (an average of 10 weeks). Primary pulmonary presentations, if symptomatic, were treated as per CNS cryptococcosis due to the high likelihood of CNS dissemination. Incidental pulmonary cryptococcoma found on routine chest radiographs were confirmed by biopsy under ultrasound or fluoroscopy guidance and booked for surgical resection. Death usually occurred early in patients who presented late. Once patients responded to therapy, mortality was usually avoided. The only cause of morbidity in survivors was visual impairment or blindness, and this was attributed mainly to intracranial hypertension with residual deficits determined by the measures taken to lower intracranial pressures. Our experience suggests that: (i) symptomatic patients should have combination therapy with 5-fluorocytosine and amphotericin B till at least a cumulative dose of 1.5 g amphotericin B is reached irrespective of whether they have primary CNS or pulmonary symptomatology; (ii) non-symptomatic pulmonary cryptococcoma could be treated primarily by surgical resection; (iii) visual failure or papilloedema should be treated aggressively; and (iv) prognosis is good with adequate therapy and early presentation.

PMID: 15190640

Scopulariopsis brevicaulis is a soil fungus normally associated with onychomycosis. It causes subcutaneous infection in immunocompromised patients and is rarely isolated from blood. A case of systemic Scopulariopsis brevicaulis infection was reported in a patient with acute myeloid leukemia. The patient developed persistent fever that did not respond to wide spectrum antibiotics and amphotericin B. Scopulariopsis brevicaulis was the only pathogen isolated from blood cultures. The fever subsided with itraconazole and there was no recurrence of fungal infection with prolonged maintenance of oral itraconazole.

Oral candidosis in non-Hodgkin's lymphoma: a case report

Siar CH, Ng KH, Rasool S, Ram S, Abdul Jalil A, Ng KP

J Oral Sci, 2003 Sep;45(3):161-4.

PMID: 14650581

Though oral candidosis is an opportunistic fungal infection that commonly affects immunocompromised patients, little is known of its occurrence as a complication of Non-Hodgkin's lymphoma. This paper reports a case of oral candidosis in a 20-year-old Indonesian woman with this lymphoproliferative disease. She presented with acute pseudomembranous candidosis on the dorsum and lateral borders of the tongue, bilateral angular cheilitis and cheilocandidosis. The latter is a rare clinical variant of oral candidosis, and the lesions affecting the vermilion borders presented as an admixture of superficial erosions, ulcers and white plaques. Clinical findings were confirmed with oral smears and swabs that demonstrated the presence of hyphae, pseudohyphae and blastospores, and colonies identified as Candida albicans. A culture from a saline rinse was also positive for multiple candidal colonies. Lip and oral lesions were managed with Nystatin. The lesions regressed with subsequent crusting on the lips, and overall reduction in oral thrush. As Non-Hodgkin's lymphoma is a neoplastic disease that produces a chronic immunosuppressive state, management of its oral complications, including those due to oral candidosis, is considered a long-term indication.
