RESUMO

The purpose of this study is to investigate the risk factors of intracranial complications in adult patients with Pott Puffy Tumor (PPT). A systematic review was conducted of clinical studies from January 1983 to December 2022 that reported on PPT adult patients. The full-text articles were reviewed for the patients' ages, sex, cultured organisms, surgical procedures, clinical sequalae, and underlying diseases that may affect the onset of intracranial complications in PPT adult patients. A total of 106 studies were included. Medical data were reviewed for 125 patients (94 males, 31 females). The median age was 45 years. A total of 52% had comorbidities, mostly head trauma (24.5%), sinus/neurosurgical operations (22.4%), immunosuppression conditions (13.3%), diabetes mellitus (9.1%), cocaine use (7.1%), or dental infections (6.1%). A total of 28 cultures revealed Streptococcus (22.4%), 24 contained staphylococci (19.2%), and 22 cultures contained other pathogens (17.6%). An amount of 30.4% developed intracranial complications, with the most common being epidural abscesses or empyemas (55.3%), as well as subdural (15.7%) and extradural lesions (13.2%). Age, DM, and immunosuppression conditions are significantly associated with intracranial complications (p < 0.001, p = 0.018 and p = 0.022, respectively). Streptococcus infection is associated with intracranial complications (p = 0.001), although Staphylococcus and other microorganisms are not. Surgical intervention, mainly ESS, and broad-spectrum antibiotics remain the cornerstones of treatment.

RESUMO

Alternaria spp. have emerged as opportunistic pathogens particularly in immunosuppressed patients. A case of a breakthrough acute invasive fungal rhinosinusitis (AIFRS), caused by Alternaria alternata, is reported in a patient with acute lymphoblastic leukemia (ALL) on anidulafungin therapy, who was successfully treated with liposomal amphotericin B and surgical intervention. To date, 20 cases of AIFRS due to Alternaria spp. have been described, 19 in the USA and 1 in Chile, making this case report the first case of AIFRS due to Alternaria in Europe. The patients had median (range) age 25 (2-56) years (65% female), almost all of them (19/20) with hematological diseases and severe neutropenia (8-41 days pre-infection). Amphotericin B was the most frequently used antifungal agent, either alone or in combination. In all of the cases, systemic antifungal therapy was combined with surgery. Despite stabilization or improvement of the AIFRS, mortality was 38% (5 days to 8 months post-surgical debridement) due to their underlying disease or other infections without sign of AIFRS at autopsy.

RESUMO

OBJECTIVES: To evaluate clinical and microbiological findings that are correlated with abscess formation in adult acute epiglottitis (AE). METHODS: We reviewed 140 cases of adult AE. Demographic, clinical, imaging, and microbiological findings are analyzed for all patients with AE in comparison to those with epiglottic abscess (EA). RESULTS: A total of 113 patients presented with AE and 27 presented or progressed to EA (19.3%). Age, sex, seasonality, smoking, body mass index (BMI), and comorbidities were statistically insignificant between the 2 groups. Muffled voice (P < .013), respiratory distress (P < .001), and pre-existence of epiglottic cyst (P < .001) are symptoms and signs connected with abscess formation. A total of 120 patients were treated conservatively. Surgical treatment was performed on 20 patients with EA. About 72 out of 80 cultures revealed monomicrobial infection. Mixed flora was isolated in 8 patients with EA. Streptococcus was isolated in 51 out of 80 positive cultures (64%). Haemophilus Influenza (Hib) was not isolated in any sample. EA and mixed flora relates to a higher rate of airway intervention (P < .001). CONCLUSION: A high level of suspicion for abscess formation is required if clinical examination reveals dyspnea, muffled voice, or an epiglottic cyst in adult with AE. The existence of EA doubles the duration of hospitalization. EA is typically found on the lingual surface of the epiglottis. Supraglottic or deep neck space expansion should be treated surgically. EA is associated with a mixed flora and a higher rate of airway obstruction. Streptococcus is discovered to be the most common pathogen.

RESUMO

Extramedullary plasmacytoma (EMP) represents a distinct yet rare entity among the plasma cell neoplasms. Given its rarity, no therapeutic consensus has been met. We report the case of a 57-year-old man with a one-year history of nasal congestion and occasional dyspnoea. Imaging showed a hypermetabolic mass in the right nasopharynx extending backward towards the adjacent oropharynx, infiltrating the epiglottis. As incisional biopsy showed histologic and immunophenotypic features consistent with plasma cell neoplasm, whereas the possibility of a marginal zone lymphoma with plasmacytic differentiation was included in the differential diagnosis. A final diagnosis of EMP was reached by using flow cytometry (FC) of a cell suspension from the neoplastic tissue. The patient received local radiotherapy (RT) which resulted to complete remission. In conclusion, flow cytometry might serve as an auxiliary method in cases where immunohistochemistry cannot differentiate between a plasma cell dyscrasia and a B-non-Hodgkin lymphoma. In cases of an established diagnosis of solitary nasopharyngeal EMP RT represents an excellent treatment modality offering prolonged disease-free survival.

RESUMO

PURPOSE: The aim of this retrospective review study is to evaluate Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score as an indicative parameter in early detecting cervical necrotizing fasciitis (CNF) from deep neck infections (DNI). METHODS: We reviewed 12 cases of CNF and 538 cases of non-necrotizing deep neck infection hospitalized in our hospital over the last decade. Cervical necrotizing fasciitis was histologically confirmed. RESULTS: Using an LRINEC score of 6 as a cutoff sensitivity was calculated at 100% (95% CI 99.9-100) and specificity 72.5% (95% CI 72.4-72.6). Negative predicted value (NPV) was 100% and positive predicted value (PPV) was 7.5%. C-reactive protein (CRP), white blood count (WBC), and glucose (Glu) levels have a higher correlation. Haemoglobin (Hb), sodium (Na), and creatinine (Cr) do not seem to have a big impact in our study. CONCLUSION: LRINEC score proves to be a useful "rule-out" tool that works on the safe side with high sensitivity and poor specificity. WBC, CRP, and Glu seem to be the most significant variables of the LRINEC score. Hb, Na, and Cr make the score safer. Decision for surgery must be based on medical history, clinical symptoms and signs, imaging findings, and laboratory tests and not according to the LRINEC score itself.

RESUMO

Head and neck squamous cell carcinoma (HNSCC) of unknown primary represents a diagnostic and therapeutic challenge for treating physicians. Detection of the primary site requires appropriate diagnostic work up. During the past few years more cases of concurrent primaries are described posing significant therapeutic dilemmas. Herein, we describe the first case of a patient with three synchronous HNSCCs.
