Researchers analyzed data on 52 HIV-positive patients with Kaposi's sarcoma (KS) aged 23-67 (74% Black, 26% White; male/female ratio = 2.8:1) referred to the Johannesburg General Hospital in South Africa during 1980-1990 to examine the hospital's experience with these patients. 23 patients had a fever and/or at least 10% weight loss. 34% had prior or coexistent opportunistic infection, particularly Pneumocystis carinii pneumonia,
fungal disease
, or tuberculosis. Possible risk factors among 21 patients were homosexual intercourse, history of sexually transmitted disease, and drug abuse. Almost all patients had skin disease, either localized or disseminated. Other KS sites included the oral cavity, regional lymph nodes, and large bowel. 90% of 20 patients treated with radiation responded to treatment. Response rates for radiation treatment among the 20 patients were 80% for symptomatic relief, 45% for complete remission, 45% for partial remission, and 10% for tumor progression. The recurrence-free period among irradiated patients was five months. Five patients developed radiation-induced mucositis of the oropharyngeal region. None of the 32 patients treated with chemotherapy and not radiation experienced complete remission. Chemotherapy induced partial remission in 38% and tumor progression in 62% of patients. 9% of chemotherapy-treated patients experienced symptomatic relief. Deteriorating performance status and/or debilitating side effects (severe mucositis and neutropenic
sepsis
) necessitated cessation of chemotherapy or dose modification. The clinical course of AIDS-related KS in this population paralleled that in Western countries. Based on these findings, the authors recommend local radiation therapy to treat AIDS-related KS or a watch-and-wait policy for asymptomatic, minimal disease in patients with an intact immune status.

We evaluated the efficacies of serum catalase (CAT), 5'-nucleotidase (5'NT), and tumor necrosis factor-alpha (TNF) as diagnostic markers of acute graft-vs-host disease (GVHD) in 28 allogeneic bone marrow transplant recipients by comparing their abilities to discriminate between GVHD-related and non-GVHD-related complications. Mean peak serum CAT concentrations for patients with GVHD-related complications (n = 17) were about fivefold higher than concentrations in patients with non-GVHD-related complications (n = 25; P = 0.003), whereas the mean peak concentrations of serum 5'NT and TNF were not substantially different. Similarly, the sensitivity and specificity of serum CAT (100% and 88%, respectively) for use as a diagnostic marker of GVHD were much better than those of serum 5'NT (88% and 24%, respectively) or serum TNF (65% and 4%, respectively). Receiver-operating characteristic plots of all possible sensitivity-specificity pairs obtained over the whole range of results also showed that serum CAT has the best diagnostic accuracy. Low specificities of serum TNF and 5'NT were caused mainly by their increase in
septicemia
,
fungal infection
, and veno-occlusive disease and after the use of granulocyte-macrophage colony-stimulating factor to stimulate donor cell engraftment. Serum CAT may prove to be a rapid and relatively noninvasive test for the diagnosis of acute GVHD.

Surgery does not cure Crohn's disease, but only its complications, as the recurrence rate that requires a new intervention is 6% per year. The resections performed by the surgeon should be as limited as possible, in order to avoid the consequent malabsorption. The identification of two forms of Crohn's disease, with different aggressiveness, has found that the stricturoplastic is an encouraging way of treatment for those forms with a prevalent stenotic component. A lot of studies have evaluated the relationships between recurrences and resections on margins microscopically free or affected by the disease. The aim of this study was a retrospective verification of the influence of any possible microscopical residue of the disease on the recurrence rate, evaluating whether the two different forms of aggressiveness of the disease (presence of stenosis or fistula) can influence the rate and precocity of the recurrence onset. In 37 patients operated for the first time of ileal or ileocolic resection, the overall recurrence rate was 18.9%; neither the presence of microscopically affected margins nor the presence of fistulas or stenosis has showed to have an influence on the onset of the recurrences. The only data that emerged is a greater precocity of the onset of recurrence in those patients whose disease was characterised by the presence of enteric fistulas. The forms in which fistulas and perforations were evident showed a recurrence rate not significantly higher than that of forms with stenosis only, but the period of time free from the disease was notably longer for the latter. In the end, patients in which typical granulomas were present showed a recurrence rate of just 9%, compared to 23% of patients in which granulomas were absent. MATERIALS AND METHODS. From 1980 through 1992, 61 patients affected by Crohn's disease were operated. There were 39 men and 22 women (mean age: 40.4 years). The mean length of the follow-up was 55.5 months. It was the first operation for 43 patients, while 9 had already undergone surgery in other hospitals; 9 patients showed anorectal complications. The operations performed on the patients for the first time have been ileal resection in the following localizations: duodenum-jejunum 4, jejunum and ileal 34, colic 5; the recurrences treated have been ileal-jejunum in 7 cases and colic in 2. In 2 cases of recurrence a stricturoplastic has been performed. RESULTS. The operative mortality was of 3 patients: 2 due to
sepsis
for anastomotic dehiscence and 1 to systemic
mycosis
. Four postoperative fistulas were observed. Recurrence of the disease occurred in 13 patients (26.5%), specifically in 21.4% of the patients operated for the first time and in 57.1% of those that were operated for recurrences. DISCUSSION AND CONCLUSIONS. In the treatment of Crohn's disease, it is important to identify any possible group with high risk of recurrence in order to undertake an appropriate medical prophylaxis. The results concerning the presence of microscopical disease on the resection margins are today still controversial. Some groups of authors prefer wide resection margins, some others are in favour of restricted resections. Our considerations let us assert that in those patients in which the resections have been performed on margins with microscopic presence of the disease, the interval before the recurrence occurs is not significantly shorter than that of patients with free margins. But the patients suffering from Crohn's disease with fistulae, probably need medical post-operative therapy to delay recurrences onset.

The aim of the present study was to analyze the main clinical and evolutive characteristics of a series of 10 patients diagnosed with
sepsis
by Candida tropicalis over a 5-year period in a Hematology Unit. The mean age of the 10 patients was 23 years (range 13-66 years) with 6 males and 4 females. Eight patients had acute leukemia, 1 non-Hodgkin's lymphoma and another patient had severe bone marrow aplasia. All the patients presented intense granulocytopenia (< 0.5 x 10(9)/L), had intravenous catheters and were receiving wide spectrum antibiotics as treatment for bacterial infection. The diagnosis of the
fungal infection
was based on the growth of C. tropicalis in blood cultures together with the evidence of tissue involvement by the fungus. Fever (> 38 degrees C) was the initial symptom of the infection in all the patients, being accompanied by myalgia in 5 cases, pleuritic pain in 2 and septic shock in 1. Violaceous erthymatomous pustules disseminated over the trunk and limbs, the histologic study of which demonstrated the presence of C. tropicalis were observed in 9 patients. Septic metastasis were found in the liver (2 cases), serosae (2 cases), the psoas muscle and the brain (1 case), respectively. Eight patients underwent treatment with amphotericin B which was complemented with 5-fluorocytosin in 6, with death occurring in the remaining 2 patients prior to the start of treatment. Three patients died with active
fungal infection
(2 by cerebral hemorrhage and 1 by septic shock). In 2 patients the infection evolved to chronic systemic candidiasis and in the remaining 5 patients infection was resolved with hemoperipheral values returning to normal.
Sepsis
by Candida tropicalis is a severe complication in patients with granulocytopenia, being mainly characterized by fever, cutaneous papulae and, to a lesser extent, muscle pain. Amphotericin B alone, or in combination with 5-fluorocytosin constitute a treatment of choice in this infection, which nonetheless is associated with an undisdainful mortality.

Neutrophilic eccrine hidradenitis (NEH) is a rare neutrophilic dermatosis occurring most frequently during induction chemotherapy for a variety of malignancies. We report a case of NEH in a 41-year-old woman with acute myeloblastic leukemia under daunorubicin, cytarabine and etoposide chemotherapy. She developed red, tender and painful nodules on a shoulder. The lesions resolved spontaneously. Histological examination is mandatory as the clinical presentation of this dermatosis is highly polymorphic. Leukemia cutis,
sepsis
, deep
fungal infection
and Sweet's syndrome must be excluded as these implicate different therapies.

Fever is associated with malignancy and is a common problem in cancer patients. Fever in the cancer patients is closely linked with infection, especially when the patient is granulocytopenic. When fever appears, a series of diagnostic and therapeutic measures must be taken even if precise knowledge of the cause of the infection is lacking. Fever can be caused by infection or by the cancer itself through tumor-related necrosis, hemorrhage or pyrogens. Infection is the more common cause, however. Bacterial and fungal
sepsis
can coexist and the bacteremia can overshadow the more difficult to determine
fungal infection
. For this reason it has become accepted practice to administer amphotericin B to granulocytopenic patients who remain febrile after a few days of broad-spectrum antimicrobial therapy and in whom no bacteria can be documented. Viral infection is rarely diagnosed in neutropenic patients without concomitant immunosuppression.

Mucormycosis is an opportunistic
fungal infection
that commonly begins by invading the respiratory tract. The purpose of the present study was to define the clinical presentation of pulmonary mucormycosis and to evaluate current treatment regimens. Thirty patients treated at our institution and 225 cases reported in the literature were reviewed. For the combined groups, the mean age at presentation was 41 +/- 21 years and associated medical conditions included leukemia or lymphoma (37%), diabetes mellitus (32%), chronic renal failure (18%), history of organ transplantation (7.6%), or a known solid tumor (5.6%). The in-hospital mortality was 65% for patients with isolated pulmonary mucormycosis, 96% for those with disseminated disease, and 80% overall. The mortality in patients treated surgically was 11%, significantly lower than the 68% mortality in those treated medically (p = 0.0004). The most common causes of death were fungal
sepsis
(42%), respiratory insufficiency (27%), and hemoptysis (13%). Pulmonary mucormycosis has a high mortality; however, antifungal agents appear to improve survival. In addition, surgical resection may provide additional benefit to patients with pulmonary mucormycosis confined to one lung.

A clinical assessment of
fungal infection
in hepatobiliary and pancreatic diseases during 1975 and 1991 was made and 25 cases of systemic
mycosis
were noted. Among 25 cases there were 20 liver diseases (hepatocellular carcinoma 12, liver cirrhosis 5, fulminant hepatitis 2, polyarteritis nodosa 1), 2 cases of gallbladder cancer and 3 cases of pancreatic cancer. The fungus was consisted of 14 cases (56%) of Candida, 9 cases of Aspergillus (36%), and 2 cases of Cryptococcus (8%).
Fungal infection
was most frequent in the lung (8 cases) and esophagus (6 cases), but rarely in the stomach, lymph node, liver, thyroid, kidney and gallbladder. Generalized fungus infection was noted in four cases (16%). Fatal
fungal infection
was complicated in liver cirrhosis (2 cases), fulminant hepatitis (one case), gallbladder cancer (one case) and cystadenocarcinoma of the pancreas (one case). In five fatal cases three cases of Aspergillus pneumonia and two cases of Candida
septicemia
were included. Glucocorticoid was used in 13 cases (52%) and anti-cancer drugs was administered in two cases (12%). However, in 9 cases (36%) without treatment of glucocorticoid or anti-cancer drug
fungal infection
was detected. In conclusion, there is a possibility of
fungal infection
in grave hepatic diseases and empirical administration of anti-fungal agent may be necessary.

Local infection and burn wound
sepsis
are one of the most severe problems in the treatment of thermally injured patients. Early surgical treatment and the use of topical antiseptics led to a decrease in the infection rate and significantly improved the survival rate of burns patients within the last twenty-five years. Many antiseptics are used in the treatment of burns. Silver nitrate, silver sulphadiazine, sulfamylon and povidone-iodine (PVP-I) are the most common substances used worldwide in burn care facilities. Clinical studies demonstrate that treatment with PVP-I is the most effective against bacterial and
fungal infection
. Several methodological problems however arise from direct comparison between these antiseptics, and local and systemic adverse effects can make the right choice difficult. Some case reports documented possible side effects in the treatment of patients with PVP-I, leading to general concerns about this treatment. Absorption of iodine and possible changes in thyroid hormones are well known, but evaluation of the clinical consequences is controversial. Reports of severe metabolic acidosis and renal insufficiency with lethal results have condemned the use of PVP-I in the treatment of extensive burns. The case reports, however, dealt with patients suffering from general morbidity and
sepsis
and therefore these single reports may not be generally valid. Local treatment of burns may cause further problems. The beneficial effect of a decrease of bacterial counts in deeper tissue may be confounded by other effects delaying wound healing, as shown in some experimental studies. Controlled clinical investigations on burn patients however are still missing. The paper will discuss these topics in detail referring to the treatment of burns with PVP-I. It is based on a critical review of the literature and the author's own experience in burns therapy.

The incidence, aetiology and clinical significance of visceral
mycoses
in HIV-infected subjects were evaluated by a retrospective survey of the clinical and microbiological records of 237 consecutive AIDS patients followed-up since 1984. Seventy-four patients out of 237 (31.2%) (56 males, 18 females; 55 IV drug abusers, 7 heterosexuals, 6 homobisexuals, 3 blood recipients and 3 children with congenitally-acquired HIV infection) presented 77 different episodes of visceral
fungal infection
as a whole, represented by candidiasis in 56 cases (oesophageal 45, pulmonary 5,
sepsis
2, eye involvement 2, endocarditis and invasive oropharyngeal infection in the remaining 2 patients), cryptococcosis in 17 cases (meningoencephalitis in all subjects, with disseminated infection in 11 of them), and aspergillosis in 4 cases (pulmonary 2, cerebral and cranio-facial in the remaining 2 patients). In 57 out of 74 patients (77%), visceral
mycoses
were diagnostic or concurrent with the diagnosis of AIDS. Fungal diseases, as a whole, showed a significantly higher incidence (p < 0.03) among drug abusers, whereas homobisexual men presented a significantly lower frequency (p < 0.001, chi-square test) than AIDS patients with other risk factors for HIV infection. The onset of cryptococcosis was significantly associated with the male sex (p < 0.005, Fisher exact test). All subjects suffering from a visceral
mycosis
were severely immunosuppressed, with a higher rate of neutropenia in patients developing Candida and Aspergillus spp. infection (23 out of 56 patients with visceral candidiasis and 3 out of 4 cases of aspergillosis had an absolute neutrophil count lower than 1500 cells/mm3), while a severe reduction in CD4+ lymphocyte count was more evident among patients with cryptococcosis (13 out of 17 patients had a CD4+ cell count lower than 50/mm3). After remission of the primary episode of
fungal infection
(obtained in 80.5% of cases), the incidence of relapse observed in a long follow-up period (mean time 57.6 +/- 39.2 weeks) was elevated both for patients with cryptococcosis (7 cases out of 17) and subjects with candidiasis (19 cases out of 53), with no significant difference among patients receiving a secondary prophylaxis or not (22 relapses observed in 53 patients treated with maintenance antifungals versus 4 episodes in 8 patients followed for a comparable mean time with no antimycotic treatment). Fifty-two out of 74 patients (70.3%) have died up to now; in 21 of them death was due to or associated with the visceral
mycosis
(cryptococcosis in 11 cases, candidiasis in 8, aspergillosis in 2).(ABSTRACT TRUNCATED AT 400 WORDS)
