Clinical and surgical factors affecting the prognosis and survival rates in patients with mucormycosis.

PURPOSE: To investigate the factors affecting disease specific mortality (DSM) in patients with mucormycosis. METHODS: This retrospective study included 24 patients diagnosed with mucormycosis and who had undergone surgical and medical treatment between 2010 and 2020. There were 14 male and 10 female patients whose mean age was 53.70 ± 16.87 years, range 18-83. We reviewed the factors affecting DSM, including the extent of disease (paranasal sinus, palatal, orbital or intracranial involvement) and blood parameters (BP) that are serum glucose level (SGL), white blood cell, neutrophil, lymphocyte counts, C-reactive protein and hemoglobulin levels. Also, the effect of SGL in diabetes mellitus and BP in hematological malignancies on DSM was additionally evaluated. RESULTS: Orbital (p = 0.001) and intracranial (p < 0.01) involvement had statistically significant effect on DSM but not the palatal involvement. When Cox regression analysis was employed to analyze the effect of multiple independent factors on DSM, only the extent of disease (p = 0.023) had statistically significant effect. Receiver operating characteristic analysis of SGL for diabetic patients demonstrated that the area under the curve was 0.917 (p = 0.016). A cut-off SGL of 360 mg/dl revealed an 83.3% sensitivity and 83.3% specificity for mortality outcome for diabetic patients having mucormycosis. CONCLUSION: Orbital or cerebral involvement is related to a poor prognosis, so early endoscopic nasal examination, diagnosis and treatment are of vital importance for DSM in mucormycosis. Serum glucose level over 360 mg/dl in uncontrolled diabetic patients with fever, ophthalmological findings and facial hypoesthesia should necessitate a consultation to an otolaryngologist and an endoscopic careful nasal examination.

Assessment of Nasal Carriage of Staphylococcus Aureus and Axillar Flora in Patients With Acromegaly.

PURPOSE: Recent study showed that patients with acromegaly have typical skin findings including increased sebum secretion, decreased transepidermal water loss, more alkaline, and colder skin surface correlated with serum growth hormone and insulin-like growth factor 1 levels. Different anatomic localizations and texture of the skin differ in bacterial concentrations.Nasal carriage of Staphylococcus aureus and axillar flora in patients with acromegaly was compared with normal population with regard to duration of acromegaly as well as the growth hormone and insulin-like growth factor 1 levels. METHODS: This patient-control prospective study was conducted in university hospitals in Mersin, Turkey. The study consisted of 30 active acromegalic patients and 60 healthy adults who had no previously diagnosed chronic illness as a control group. A total of 90 volunteers were enrolled in this study; nasal and axillar cultures were obtained. Axillar and nasal specimens from anterior nares of the individuals were taken using sterile swabs. RESULTS: Nasal colonization of Staphylococcus aureus was 13.3% in acromegalic patients, but 43.4% in control group. This difference was statistically significant (P = 0.004). Patients and control group compared according to axillar cultures, the authors determined proteus colonization 16.7% in patients with acromegaly but no proteus colonization in control group. This result was statistically significant (P = 0.001). Proteus colonization was negatively correlated only with disease duration in acromegalic patients (P = 0.017). CONCLUSION: The authors demonstrated that compared with healthy subjects, acromegalic patients had low percentage of nasal carriage of Staphylococcus aureus and more gram-negative basili in the axillar flora. These nasal and axillar flora changes should be considered for prophylactic antibiotics use before surgery and ampiric antibiotics use after surgery.

The influence of direct rigid laryngoscopy on the nosocomial colonization and bacteremia.

OBJECTIVE: Direct rigid laryngoscopy (DRL) is a relatively simple and well-tolerated procedure that can provide both diagnostic and therapeutic benefits. There are no data regarding the risk of acquiring bacteremia after DRL. The purpose of this prospective study was to assess the frequency of bacteremia and nosocomial colonization following DRL and to identify possible risk factors for the development of these complications. METHODS: In this study, 55 consecutive patients with benign or malignant laryngeal pathologies undergoing DRL were included between January 2010 and January 2011. The patients have benign laryngeal lesions and suspicious malignancy. In appropriate circumstances of each patient before intubation and at postoperative 24 hours of throat swab, samples were taken in the transport medium of the patients who underwent planned DRL and underwent surgery. The samples were evaluated in our Microbiology Department. Blood cultures were performed using automated system at postoperative 5 and 24 hours. For each patient at preoperative and postoperative period, C-reactive protein levels in blood samples were measured. SPPS 16 package program was used for statistical analysis. RESULTS: The distribution of sex was 45 males and 10 females with average age of 51.4 (between 23 and 99 years). Patients who had malignant lesions (n = 17) accounted for 30.9% of all patients. Preoperative Candida colonization was recovered from the cultures obtained from 9 oropharyngeal specimens (16.4%). Postoperative oropharyngeal nosocomial bacteria colonization was observed in 14 patients (25.5%). Nosocomial colonization was found related to malignancy (P = 0.014). C-reactive protein levels of patients before and after surgery were not statistically significant (P > 0.05). At postoperative 5 and 24 hours, blood cultures of all patients were negative. Postsurgical bacteremia was not observed. CONCLUSIONS: Although there is no association between DRL and bacteremia, nosocomial colonization may be significant. Nosocomial colonization possesses a risk of development of infection especially in patients with malignancy.

Rhino-orbito-cerebral mucormycosis in patients with diabetic ketoacidosis.

Mucormycosis is a life-threatening fungal infection that occurs in immunocompromised patients. The most common predisposing risk factor for mucormycosis is diabetes mellitus. Rhino-orbito-cerebral mucormycosis is the most common form in diabetic patients and is characterized by paranasal sinusitis, ophthalmoplegia with blindness, and unilateral proptosis with cellulitis, facial pain with swelling, headache, fever, rhinitis, granular or purulent nasal discharge, nasal ulceration, epistaxis, hemiplegia or stroke, and decreased mental function. Diabetic ketoacidosis is the most common and serious acute complication of diabetic patients. We herein report 2 cases of fatal rhino-orbito-cerebral mucormycosis in a patient with diabetic ketoacidosis.

Brucella melitensis infection within warthin tumor of the parotid gland.

Brucellosis is a zoonotic systemic infectious disease, and multiorgan involvement is commonly seen, but involvement of the neck is a rare presentation of brucellosis. Granulomatous infections of the parotid gland are extremely rare. Warthin tumor is a well-known benign neoplasm of the salivary glands. In this report, we describe a Warthin tumor associated with Brucella melitensis in the same parotid gland.

Bloodstream infections and mortality-related factors in febrile neutropenic cancer patients.

BACKGROUND: We performed a prospective observational cohort study to evaluate the causative bacteria and to identify risk factors for mortality in febrile neutropenic (FN) patients with blood stream infection (BSI). MATERIAL/METHODS: We conducted a prospective data collection on all patients with bacteremia or fungemia. The patients were assigned into low-risk and high-risk groups in accordance with the Multinational Association for Supportive Care in Cancer (MASCC) Risk Index. RESULTS: Throughout the study period, the patients developed 420 FN episodes. Out of 420 episodes, only 90 (21.4%) were found to have bloodstream infection. The mean age of the patients was 45.6±18.4 years and 55.6% of the patients were male. A total of 98 isolates were recovered from the cases of BSI. Coagulase-negative Staphylococcus spp (CoNS) were the most common isolates overall (33.7%). There was a significant increase in the rate of gram-negative bacteria throughout the study period (p=0.028). Overall mortality was 33%. Multivariate analyses showed that MASCC risk scores (p=0.0001, OR=15.1, CI%95 4.5-50.7), ICU wards (p=0.0002, OR= 8.6, Cl%95 1.101-68,157) and CoNS (p=0.004, OR=12.12, CI%95 2.3-64.7) were independent risk factors associated with mortality. BSI due to CoNS was associated with lower mortality; however, MASCC high risk score and ICU stay were associated with higher mortality. CONCLUSIONS: The MASCC risk-index score and emergence of CoNS in positive blood cultures are valuable tools in the management of FN.

Risk factors for infections caused by multidrug-resistant bacteria in patients with solid tumours.

OBJECTIVES: We aimed to determine the risk factors for healthcare-associated infections (HCAI) caused by multidrug-resistant (MDR) bacteria in patients with solid tumours. METHODS: This retrospective study was performed in the Department of Clinical Microbiology and Infectious Diseases, Mersin Teaching and Research Medical Centre, between January 2004 and December 2008. SPSS version 11.5 program package was used for the statistical analyses. RESULTS: A total of 145 patients who had an HCAI were analyzed; 62% of the patients were male and their median age was 57.7 ± 16 y and median Charlson co-morbidity score was 4.94 ± 1.2. During the study period, 83 MDR bacteria were isolated from HCAIs that developed in 70 (48.3%) patients. In multiple binary logistic regression analysis, duration of hospital stay (odds ratio (OR) 1.041, 95% confidence interval (CI) 1.007-1.077; p = 0.019), surgery (OR 3.115, 95% CI 1.288-7.535; p = 0.012), use of glycopeptides (OR 5.394, 95% CI 1.960-14.850; p = 0.001), and use of third-generation cephalosporins (OR 5.521, 95% CI 2.017-15.110; p = 0.001) were found to be independent risk factors for the development of an MDR infection. CONCLUSIONS: Among hospitalized patients with a solid tumour, HCAIs caused by MDR bacteria occurred more frequently in patients undergoing surgery, receiving third-generation cephalosporins and glycopeptide antibiotics, and having a prolonged hospital stay.

Increase in Candida parapsilosis fungemia in critical care units: a 6-years study.

OBJECTIVES: We aimed to asses possible clinically significant differences between C. parapsilosis and other candida species candidemia receiving care in the intensive care unit (ICU) setting. METHODS: The study included 118 adult patients diagnosed as candidemia after admission to the ICU of a university hospital between January 2004 and December 2009. Data about demographic characteristics, underlying diseases, and risk factors for ICU-related candidemia were collected. RESULTS: During the study period, 118 patients with candidemia were identified among 2,853 patients admitted into the ICU. Candidemia was seen in 41.4 cases per 1,000 ICU admissions. The overall incidence of candidemia in ICU patients during the study period was 2.09 per 1,000 hospital admissions. Of the isolates, 18.6% were C. albicans and 81.4% were C. non-albicans. The species most frequently isolated was C. parapsilosis (66.1%, 78/118). The distribution of other Candida spp. was as follows: 15 had C. tropicalis (12.7%) and 3 had C. glabrata (2.5%). By Statistical analysis, when patients with candidemia who had C. parapsilosis were compared with other Candida spp., the following factors were found to be significantly associated with C. parapsilosis fungemia; intravascular catheters (p = 0.008), malignity (p = 0.049) and age (p = 0.039). Relationship was found between C. tropicalis and hematologic malignancies (p = 0.001). CONCLUSIONS: When infections with a high mortality such as candidemia is suspected in critically ill patients, it is important to know local risk factors and epidemiological distributions of causative agents in selection of empirical and effective antifungal treatment.

[Lesions of tuberculosis in the head and neck region: a retrospective analysis of 48 cases]. / Bas boyun bölgesi tüberküloz lezyonlari: 48 olgunun geriye dönük analizi.

OBJECTIVES: We evaluated patients who had been treated for head and neck tuberculosis. PATIENTS AND METHODS: This retrospective study included 40 patients (28 males, 20 females; mean age 32.6 years; range 11 to 65 years) who had received treatment for tuberculosis of the head and neck region between January 2000 and June 2009. Clinical findings, treatment modalities, and the results of treatment were evaluated. RESULTS: Forty-one patients had cervical lymphadenopathy, two patients had parotid gland tuberculosis, two patients had nasopharyngeal tuberculosis, and three patient were diagnosed as tongue, tonsil and larynx tuberculosis respectively. Lymph nodes in the posterior triangle were found to be the most common region afflicted by tuberculosis lymphadenitis. Diagnosis was confirmed by excisional biopsy in all patients and lesions were resolved after antituberculosis chemotherapy. CONCLUSION: Although different clinical presentations were seen, tuberculosis cervical lymphadenitis is the most common presentation of tuberculosis in the head and neck region. Tuberculosis should be considered in the differential diagnosis of the neck mass and other head and neck lesions.
