A Systematic Review of Intracranial Complications in Adults with Pott Puffy Tumor over Four Decades.

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.

Breakthrough Acute Necrotizing Invasive Fungal Rhinosinusitis by Alternariaalternata in a Patient with Acute Lymphoblastic Leukemia on Anidulafungin Therapy and Case-Based Literature Review.

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.

Ubi pus, ibi evacua: a review of 601 peritonsillar abscess adult cases.

BACKGROUND: Peritonsillar abscess (PTA) is the most common deep neck infection, occurring as a consequence of bacterial acute tonsillitis or as a result of infection of the Weber glands, with frequent and life-threatening complications. AIM: To investigate several factors associated with complications and worse prognosis, such as defining the method of surgical drainage and treatment of a PTA which remains an area of controversy in the literature METHODS: The purpose of this retrospective study is to examine the epidemiological, clinical, and laboratory findings of 601 adult patients and to discuss them along with their treatment plan. RESULTS: Pharyngalgia was the most common reported symptom, followed by trismus, odynophagia, fever, hot potato voice, malaise, and cervical lymphadenopathy. Sixty-eight patients developed complications. Streptococcus species were the most common pathogens. A statistically significant difference was found in days of hospitalization, WBC and CRP levels, age, and the pre-existing systemic diseases between patients with and without complications. A comparison of patients treated with intravenous and oral antibiotics revealed no statistically significant difference. CONCLUSION: Οver 10% of PTA cases may develop complications, the most common of which is extension into deep neck spaces. Comorbid conditions increase the risk of complications. Despite the wide range of treatment strategies, incision and drainage remain the cornerstone of surgical treatment. In patients with no comorbidities, intravenous antibiotics appear to have no advantage over oral antibiotics.

Clinical and Microbiological Factors Associated With Abscess Formation in Adult Acute Epiglottitis.

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.

Solitary extramedullary plasmacytoma of the nasopharynx: The role of flow cytometry.

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.

Early detecting cervical necrotizing fasciitis from deep neck infections: a study of 550 patients.

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.

Multiple synchronous squamous cell carcinomas of the head and neck: A case report.

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.

Detection of local allergic rhinitis in children with chronic, difficult-to-treat, non-allergic rhinitis using multiple nasal provocation tests.

BACKGROUND: There is little evidence on the incidence and characteristics of local allergic rhinitis (LAR) in children. Most studies have included subjects with perennial rhinitis only, and results are based on the investigation of no more than three allergens per study. Our aim was to determine the proportion of children with LAR amongst children with chronic, difficult-to-treat, perennial or seasonal, rhinitis but no evidence of sensitization to aeroallergens, or other alternative diagnosis. METHODS: We performed multiple nasal provocation tests (M-NPTs) with four locally relevant aeroallergens (Phleum pratense, Olea europea, Alternaria alternata, and Dermatophagoides pteronyssinus) in children with absence of aeroallergen sensitization, seen during a calendar year in a specialized rhinitis clinic. We additionally performed single NPT to children with allergic rhinitis (AR; positive control group). The result of the NPT was based on symptoms and acoustic rhinometry. Identification of nasal hyper-reactivity (NHR) triggers was through a questionnaire. RESULTS: Local allergic rhinitis was confirmed in 29.2% (7/24) of the negative SPT/blood testing population. All but one of the children reacted to one allergen and one to two. All AR children had positive single NPT with results similar to the LAR. There were no differences in age at examination and rhinitis onset, gender distribution, family atopy, and past or current environment of residency, while the prevalence of reported NHR triggers was comparable amongst the three groups. CONCLUSION: This is the first pediatric study where the seasonal or perennial rhinitis population was thoroughly tested for LAR against four aeroallergens. LAR is present in a considerable proportion of children with chronic, difficult-to-treat rhinitis and no sensitization to aeroallergens, and therefore, the performance of NPT should be strongly considered in these cases. There were no distinct clinical characteristics between LAR, AR, and non-allergic rhinitis in children.
