A 28-year-old male presented with a low grade fever, decreased activity, left hemiparesis and signs of intracranial hypertension. CT showed a moderate hydrocephalus and a large irregular mass in the right temporoparietal region with garland-like enhancement after injection of the contract medium. These findings suggested a malignant brain tumor. MR images demonstrated a mass with low-iso signal intensity on T1 weighted image and low-iso-high mixed intensity on T2, which is like a mosaic pattern. Multiple cerebrospinal fluid space seedings including the wall of the lateral ventricle, the surface of the cerebellum and pons, and the cervical spinal cord were clearly delineated on MR images after Gd-DTPA injection. The large mass was totally removed by craniotomy after ventricle drainage for hydrocephalus. Microscopic examinations showed dense fibrous connective tissue with infiltration of Langhans' giant cells, lymphocytes and fibroblasts around the necrotic centers. These hard components may have been responsible for the low signal intensity on T2-MR images. Many Candida elements were clearly shown with the periodic acid Schiff stain. The diagnosis was that the lesion was an intraparenchymal granuloma due to Candida infection. The patient died on the 8th postoperative day because of brain stem malfunction. Intracranial fungal infection rarely produces a granuloma in the central nervous system. Though it is difficult to diagnose a large irregular mass in the brain, MR images, especially T2 weighted images are useful for the diagnosis of fungal granuloma.

The sudden onset of hypertension mandates investigation for secondary causes. We report the case of a young man with a very rare systemic fungal disease that included massive unilateral perirenal adenopathy. Treatment was associated with the abrupt onset of severe hypertension. Imaging studies suggested progressive constriction of one kidney with treatment, presumably as a result of healing adenopathy. We suggest that this case is a new example of hypertension secondary to constrictive perinephritis (Page kidney).

The first case of a cutaneous cryptococcosis associated with systemic erythematous lupus (SLE) diagnosed in our Mycology Reference Centre is presented: a 24-year-old female patient diagnosed with SLE, nephrotic syndrome, arterial hypertension, renal insufficiency due to glomerulonephritis type IV and cellulitis in the right thigh and gluteus. Cryptococcus neoformans was isolated by cutaneous biopsy and haemoculture. Cryptococcal antigen was detected in serum by the latex agglutination test. As the patient did not respond to fluconazol intravenous treatment, amphotericin B administration was performed. She died of acute renal insufficiency.

Fungal infection of the genitourinary system is a relatively uncommon presentation. Cryptococcuria has rarely been recognized in clinical practice. Patients with positive urine culture for Cryptococcus neoformans from 1992 to 2003 were retrospectively reviewed. Sixteen patients were identified. Nine (56%) patients were male, with a mean age of 44 +/- 21 (range, 16-88) years. Fifteen (94%) patients had underlying conditions such as HIV infection, diabetes mellitus, hypertension, and/or systemic lupus erythematosus. Thirteen (81%) patients had cryptococcuria as a manifestation of disseminated cryptococcosis, and the rest had only isolated cryptococcuria. Urinary analysis revealed proteinuria (75%), pyuria (31%), and budding yeast (13%). Nine (56%) patients received antifungal therapy. Other patients were misdiagnosed or died before treatment. The mortality rate was 64%. In conclusion, cryptococcuria is not extremely rare and can present as a manifestation of disseminated cryptococcosis or isolated urinary tract infection.

A promising approach to improving outcomes in patients with cryptococcal meningitis is to use adjunctive passive immunotherapy with a monoclonal antibody (MAb) directed against the capsular polysaccharide of Cryptococcus neoformans. This is the first application of MAb therapy for the treatment of a fungal disease in humans. We determined the safety and maximum tolerated dose of the murine anticryptococcal MAb 18B7 in a phase I dose-escalation study. The subjects were human immunodeficiency virus-infected patients who had been successfully treated for cryptococcal meningitis. Six dosing cohorts received MAb 18B7 at 0.01 to 2 mg/kg of body weight as a single infusion. Three patients each received 0.01, 0.05, 0.2, and 0.5 mg of MAb 18B7 per kg without significant adverse events. Four of the subjects who received the 1-mg/kg dose had mild study drug-associated toxicity, including transient nausea, vomiting, back pain, and urticarial rash. Two of the subjects who received 2 mg/kg developed drug-associated mild to moderate nausea, vomiting, chills, and myalgias. One of the subjects who received 2 mg/kg developed intracranial hypertension 10 weeks after MAb 18B7 administration. Serum cryptococcal antigen titers in the cohorts receiving doses of 1 and 2 mg/kg declined by a median of twofold at 1 week and a median of threefold at 2 weeks postinfusion, but the titers subsequently returned toward the baseline values by week 12. The half-life of MAb 18B7 in serum was approximately 53 h, while the MAb was undetectable in the cerebrospinal fluid of all patients. These data support the continued investigation of MAb 18B7 at a maximum single dose of 1.0 mg/kg.

Acute pancreatitis develops immediately after the causative impulse, while chronic pancreatitis develops after the long-term action of the noxious agent. A typical representative of acute pancreatitis is biliary pancreatitis, chronic pancreatitis develops in alcoholism and has a long latency. As alcoholic pancreatitis is manifested at first as a rule by a potent attack, it is classified in this stage as acute pancreatitis. The most frequent etiological factors in our civilization are thus cholelithiasis and alcoholism (both account for 20-50% in different studies). The assumed pathogenetic principles in acute biliary pancreatitis are the common canal of both efferent ducts above the obturated papilla, duodenopancreatic reflux and intrapancreatic hypertension. A detailed interpretation is however lacking. The pathogenesis of alcoholic pancreatitis is more complicated. Among others some part is played by changes in the calcium concentration and fusion of cellular membranes. Idiopathic pancreatitis occurs in up to 10%, part of the are due to undiagnosed alcoholism and cholelithiasis. Other etiologies are exceptional. Similarly as in cholelithiasis pancreatitis develops also during other pathological processes in the area of the papilla of Vater such as dysfunction of the sphincter of Oddi, ampulloma and juxtapapillary diverticulum, it is however usually mild. The incidence of postoperative pancreatitis is declining. Its lethality is 30% and the diagnosis is difficult. In the pathogenesis changes of the ion concentration are involved, hypoxia and mechanical disorders of the integrity of the gland. Pancreatitis develops in association with other infections--frequently in mumps, rarely in hepatitis, tuberculosis, typhoid and mycoses. Viral pancreatitis is usually mild. In parasitoses pancreatitis develops due to a block of the papilla Vateri. In hyperparathyroidism chronic pancreatitis is more likely to develop, recent data are lacking. As to dyslipoproteinaemias, pancreatitis develops in the Ist, IVth and Vth type of Frederikson's classification, in rare recessive disorders and other conditions such as hypothyroidism, renal insufficiency, oestrogen substitution and others. In pancreas divisum chronic pancreatitis is more likely to develop. In exotic countries tropical pancreatitis is most frequent. It is however similarly as alcoholic pancreatitis primarily chronic. A very serious course is usual in traumatic pancreatitis. Risk factors of pancreatitis after ERCP are in particular undilated biliary pathways, dysfunction of the sphincter of Oddi and the use of a needle knife (bistoury). Medicamentous prevention is not substantiated. Drug induced pancreatic damage is much rarer than hepatotoxicity. Pancreatitis is caused most frequently by immunosuppressives, methyldopa, corticoids and oestrogens. The question remains to what extent the course of pancreatitis is influenced by its etiology. Biliary, alcoholic, traumatic and postoperative pancreatitis is usually severe, pancreatitis associated with viroses and induced by drugs is usually mild.

Amphotericin B (AmB) is a crucial agent in the management of serious systemic fungal infections. In spite of its proven track record, its well-known side effects and toxicity will sometimes require discontinuation of therapy despite a life-threatening systemic fungal infection. The mechanism of action of AmB is based on the binding of the AmB molecule to the fungal cell membrane ergosterol, producing an aggregate that creates a transmembrane channel, allowing the cytoplasmic contents to leak out, leading to cell death. Most of the efforts at improving AmB have been focused on the preparation of AmB with a lipid conjugate. AmB administration is limited by infusion-related toxicity, an effect postulated to result from proinflammatory cytokine production. The principal acute toxicity of AmB deoxycholate includes nausea, vomiting, rigors, fever, hypertension or hypotension, and hypoxia. Its principal chronic adverse effect is nephrotoxicity. AmB probably produces renal injury by a variety of mechanisms. Risk factors for AmB nephrotoxicity include male gender, higher average daily dose of AmB (> or = 35 mg/day), diuretic use, body weight > or = 90 kg, concomitant use of nephrotoxic drugs, and abnormal baseline renal function. Clinical manifestations of AmB nephrotoxicity include renal insufficiency, hypokalemia, hypomagnesemia, metabolic academia, and polyuria due to nephrogenic diabetes insipidus. Human studies show convincingly that sodium loading in excess of the usual dietary intake notably reduces the incidence and severity of AmB-induced nephrotoxicity.

Lentinus edodes is the first medicinal macrofungus to enter the realm of modern biotechnology. It is the second most popular edible mushroom in the global market which is attributed not only to its nutritional value but also to possible potential for therapeutic applications. Lentinus edodes is used medicinally for diseases involving depressed immune function (including AIDS), cancer, environmental allergies, fungal infection, frequent flu and colds, bronchial inflammation, heart disease, hyperlipidemia (including high blood cholesterol), hypertension, infectious disease, diabetes, hepatitis and regulating urinary inconsistencies. It is the source of several well-studied preparations with proven pharmacological properties, especially the polysaccharide lentinan, eritadenine, shiitake mushroom mycelium, and culture media extracts (LEM, LAP and KS-2). Antibiotic, anti-carcinogenic and antiviral compounds have been isolated intracellularly (fruiting body and mycelia) and extracellularly (culture media). Some of these substances were lentinan, lectins and eritadenine. The aim of this review is to discuss the therapeutic applications of this macrofungus. The potential of this macrofungus is unquestionable in the most important areas of applied biotechnology.

We report a 16 years old boy with diagnosis of Acute Myeloid Leukemia with severe immune suppression secondary to his primary disease and to leukemia's treatment. Early during the course of his chemotherapy he developed symptoms and signs compatible with invasive fungal disease (IFD). Lungs were primarily compromised followed by CNS involvement with manifestations of intracranial hypertension. Laboratory exams were remarkable for prolonged neutropenia and indirect evidence of Aspergillus sp infection, with successive detection of positive and increasing levels of galactoman antigen in serum. With this case we want emphasize the great importance of invasive fungal disease in immune suppressed patients and particularly the CNS compromise. This represents a medical emergency which deserves to start a complete and comprehensive microbiology diagnosis and concomitantly start an empiric antifungal treatment. The importance of neuroimaging for a correct identification of the number, location and size of CNS lesions must be highlighted. The election of MRI, if available, should be preferred due to a better performance than CT scan. Brain biopsy should be discussed when all the non invasive attempts for etiology identification have failed. The invasive fungal CNS compromise has medical treatment and the surgical drainage has to be considered for lesions greater than 2 cm or for those making a mass effect or have failed with medical treatment.
