Synchronous laryngeal cancer.

Multiple primary cancers are usually defined as primary malignant tumors of different histological origins in one person. Synchronous cancers are defined as two or more primary cancers diagnosed in the same patient at the same time or within six months after identifying the first tumor, and those cancers that develop at more than a six-month interval are termed as metachronous multiple primary cancers. Our study comprised of a patient with synchronous laryngeal cancer with double localizations. The case was solved through surgical excision of the tumors. Histopathological and immunohistochemistry examinations revealed synchronous laryngeal cancer. Laryngeal cancer should usually be managed through surgical resection, followed by oncological treatment.

HPV and Other Risk Factors Involved in Pharyngeal Neoplasm-Clinical and Morphopathological Correlations in the Southwestern Region of Romania.

Oropharyngeal squamous cell carcinoma (OPSCC) development is strongly associated with risk factors like smoking, chronic alcohol consumption, and the living environment, but also chronic human papilloma virus (HPV) infection, which can trigger cascade cellular changes leading to a neoplastic transformation. The prevalence of these factors differs among different world regions, and the prevention, diagnosis, and prognosis of OPSCC are highly dependent on them. We performed a retrospective study on 406 patients diagnosed with OPSCC in our region that were classified according to the tumor type, localization and diagnosis stage, demographic characteristics, risk factors, and histological and immunohistochemical features. We found that most of the patients were men from urban areas with a smoking habit, while most of the women in our study were diagnosed with tonsillar OPSCC and had a history of chronic alcoholism. During the immunohistochemical study, we analyzed the tumor immunoreactivity against anti-p16 and anti-HPV antibodies as markers of HPV involvement in tumor progression, as well as the correlation with the percentage of intratumoral nuclei immunomarked with the anti-Ki 67 antibody in serial samples. We observed that the percentage of Ki67-positive nuclei increased proportionally with the presence of intratumoral HPV; thus, active HPV infection leads to an increase in the rate of tumor progression. Our results support the implementation of strategies for OPSCC prevention and early diagnosis and can be a starting point for future studies aiming at adapting surgical and oncological treatment according to the HPV stage for better therapeutic results.

Cutaneous Malignant Melanoma Metastatic to the Larynx and Trachea: A Case Report and Review of the Literature.

Malignant melanoma rarely develops in mucous membranes. Statistical data show that approximately 0.6-9.3% of patients with cutaneous malignant melanoma will develop metastases in the upper aerodigestive tract mucosa, and within these metastatic sites, the least common are the laryngeal and tracheobronchial ones. This exceedingly rare clinical entity has no clear treatment recommendations; radical surgery does not seem to benefit the patient in term of life expectancy. We present the case of a 56-year-old male patient diagnosed with laryngeal and tracheobronchial melanoma metastases. Prior to admission to our clinic the patient had a personal history of malignant melanoma of the nuchal region operated on 7 years ago, malignant melanoma of the gallbladder and metastatic left axillary polyadenopathy for which he underwent surgical treatment 3 months prior. Histopathological and immunohistochemical reports established the diagnosis of laryngeal metastasis of malignant melanoma. Genetic molecular analysis was positive for B-Raf (BRAF) gene and hence Vemurafenib was administered, with a favorable outcome at the one-year follow-up. Nevertheless, there are currently no clear universally accepted guidelines for the treatment of laryngeal melanoma, mainly due to the rarity of this clinical entity. We conducted a review of similar cases reported in the literature. Interestingly, reviewing the cases reported in the literature, it appears that laryngeal metastases of a primary cutaneous melanoma are more common in men, with an average time to metastasis of 4.3 years.

Multicenter Epidemiological Study of Nosebleeds Requiring Hospitalization.

Epistaxis is a common presenting symptom either emergency condition or ambulatory in Otorhinolaryngology, affecting people of all ages. A multicentric retrospective descriptive study of 380 patients who were hospitalized with epistaxis over a 3.8 year period was carried out. Data collected was analyzed using IBM SPSS Statistics 25 and illustrated using Microsoft Office/Word 2016. The current study showed that male adults after 60 years old are most affected by nasal bleeding. More than half of hospitalized patients have severe epistaxis at the time of hospitalization. However, further studies are necessary to be done in order to fully elucidate the epidemiology of nosebleeds requiring hospitalization.

Etiological Profile of Epistaxis: Pre-Pandemic Versus Pandemic.

Nosebleed or epistaxis is one of the most common forms of presenting an emergency in the ENT field. Since March 11, 2020, the World Health Organisation has proclaimed COVID-19 a global pandemic, and the world has been closed down. The main objective of the study is to analyse and compare the dynamics of epistaxis aetiology among the cases that required hospitalisation in the pre-pandemic period and the period of the COVID 19 pandemic. The study is multicenter retrospective from October 2018 to May 2022, including 380 cases of hospitalised epistaxis, with the mention that March 2020 is considered the beginning of the pandemic period. 60.8% of the patients enrolled in the study in the pre-pandemic period (60.8%) and 39.2% in the pandemic period. Differences between groups were not statistically significant between study entries (pre-pandemic vs. pandemic) and age (p=0.331), gender (p=0.916) or existence of local causes for epistaxis (p=0.895). Patients with general causes for epistaxis were more frequently enrolled in the pandemic period, while patients without general causes for epistaxis were more frequently enrolled in the pre-pandemic period. Patients with a hospitalisation period of more than 5 days were more frequently enrolled in the pre-pandemic period while patients with a hospitalisation period of 3 to 5 days were more frequently enrolled in the pandemic period. Also, patients with idiopathic epistaxis were more frequently enrolled in the pre-pandemic period. Based on the results presented in our study, the period of the Covid 19 pandemic directly influenced both the number of patients and the period of hospitalisation.

Kaposi's sarcoma of the larynx: case series.

Kaposi's sarcoma (KS) represents a type of cancer that usually arises on the skin and very rarely in other organs. KS-associated herpesvirus (KSHV), also known as human herpesvirus-8 (HHV-8) commonly arises in patients with acquired immunodeficiency syndrome (AIDS). Laryngeal involvement of KS is very rare. Our study comprised of three cases with laryngeal KS. All cases were solved through surgical excision of the tumor. Histopathological and immunohistochemistry examinations revealed laryngeal KS. Laryngeal KS should be managed through surgical resection, followed by oncological treatment.

Reconstructive challenges of sinonasal tumors: A case report.

Sinonasal tumors are an uncommon pathological entity and applying the optimal treatment may represent a challenge, even for experienced physicians. A various number of techniques and materials may be used in the reconstruction of craniofacial defects following surgery for extensive sinonasal cancer. The aim of the present study was to present the case of a 33-year-old male patient diagnosed with a large sinonasal tumor and discuss the challenges faced while selecting the most suitable rehabilitation technique. In the present case, it was decided that the optimal solution was to use a craniofacial prosthesis in order to cover the entire defect, as well as a temporoparietal flap. In summary, reconstructive interventions must always be adapted to each individual patient and a multimodal approach may lead to a highly satisfactory outcome, for both the patient and the surgical team. All the reconstructive solutions available must always be kept in mind and adapted to the individual requirements of each case, taking into consideration both the extent of the tumor and the comorbidities of the patient, as there is no one solution that is considered as optimal for all patients.

Endoscopic assessment of sinonasal mucormycosis with SPIES: The 'battlefield' sign.

Sinonasal mucormycosis is an extremely challenging pathology for the ear, nose and throat (ENT) surgeon from a therapeutic point of view. The disease affects immunocompromised patients and exhibits lethal potential. Although the diagnosis is relatively easy to suspect due to the distinctive clinical aspects which consists of black crusting present in the nasal fossae able to be confirmed by biopsy, the treatment requires resection of all affected tissue with safety limits. Due to the tendency of invasion associated with this fungal infection and taking into account the location involved (the sinonasal area) and the grave condition of these patients, it is extremely important to perform only the minimal resection necessary, but that includes all tissue infected by the fungus. This article presents a minimally invasive method of evaluation that can be performed during endoscopic surgical intervention and that aids the surgeon to better evaluate the affected area. It is associated with no additional risks for the patients, but it helps the surgeon to perform the intervention efficiently while not damaging healthy tissue. The authors consider that the method presented will aid the surgeon during the endoscopic surgical intervention in evaluating the lesion and resecting all the affected tissue while preserving healthy areas.

Arterial only anastomosis associated with modified Baudet technique in ear replantation: Case reports and literature review.

BACKGROUND: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice. We propose the association of microsurgical techniques with some modification (modified Baudet technique) to obtain higher survival rate of the reimplanted stump. METHODS: This study included cases of 3 male patients with total ear amputation, the injuries and their mechanism (workplace accident) being identical. Chief complaints were pain, bleeding, important emotional impact due by an unaesthetic appearance. The established diagnosis was traumatic complete ear amputation (grade IV auricular injury according to Weerda classification). Microsurgical replantation was performed only with arteriorraphy, and no vein anastomosis. Cartilage incisions and skin excisions were made to enlarge the cartilage-recipient site contact area. Medicinal leeches were used to treat venous congestion, to which systemic anticoagulant therapy was added. RESULTS: The results showed the survival of the entire replanted segment in all cases, with good function and esthetical appearance. Patients were fully satisfied with the final outcome. CONCLUSION: Microsurgical replantation is the gold standard, for the surgical treatment of total ear amputation. We believe that cartilage incisions and the increased surface of contact between cartilage and recipient site has an adjuvant role in revascularization of the amputated stump (with only arterial anastomosis) and the use of hirudotherapy helps to relieve early venous congestion.

Histopathological Features of Chronic Rhinosinusitis with Nasal Allergic Polyps.

Chronic rhinosinusitis with nasal polyps of allergic etiology is one of the most common pathology in the ENT sphere that affect a significant percentage of population. The paper aims to establish the involvement of the allergic component in the genesis of nasal polyposis. The study included 150 nasal polyps from patients hospitalized and operated in the ENT Department of Craiova's Clinical Emergency County Hospital. The biological material was fixed in 10% buffered formalin, processed by classical paraffin embedding technique followed by hematoxylin-eosin staining and it was interpreted in the Pathology Department of the same hospital. We evaluated a number of histopathological parameters that were given severity scores. The most common changes at epithelial level were: basal layer hyperplasia observed in 87 cases (58%), goblet cell hyperplasia in 121 cases (80.66%), basal membrane thickening with values between 10-42µm corresponding to a number of 118 cases (78.66%). The most important stromal changes were edema in 88% and infiltration with eosinophils 100%, indicating the allergic nature of this disease.

Involvement of inflammatory cells in chronic rhinosinusitis with nasal polyps.

Inflammation plays an important role in the pathogenesis of nasal polyps. Understanding the biomolecular action mechanisms of inflammatory elements can contribute to improving the prognosis of these lesions. The study analyzed the distribution and immunohistochemically quantified eosinophils [eosinophil major basic protein (BMK-13)], lymphocytes [cluster of differentiation (CD) 4, CD8, CD20] and plasmocytes (CD138) in both the epithelial and stromal compartment in relation to composite scores, which included specific histopathological parameters for 50 sinonasal polyps. Inflammatory elements predominated at stromal level, the high histological composite scores being frequently associated with increased expression of inflammatory elements. Also, the numerical distribution of inflammatory elements indicated positive linear relations within the groups BMK-13∕CD8 and CD4∕CD20∕CD138, and a negative linear relation between the two groups. This aspect can support the existence of alternative or sequential pathogenic mechanisms involved in the pathogenesis of sinonasal polyps, and the results obtained can be used for a better stratification of patients in order to optimize the therapy.

Basal cell carcinoma and basosquamous carcinoma, two faces of the same condition?

Basal cell carcinoma (BCC) is the most common locally invasive malignant epidermal neoplasm. It is generally a tumor that runs a slow progressive course and can usually be cured by surgery. Basosquamous carcinoma is considered by some authors a rare subtype of BCC, while others describe it as independent tumor with different evolution from BCC. The aim of the study was to present a very interesting case of initially otherwise ordinary BCC that during its repeated and extensive relapses changed its histopathology in a basosquamous carcinoma, despite the free surgical margins and leading to major surgeries with loss of right eye. We present a case of 75-year-old male diagnosed in 2008 with a tumor located in the right naso-orbital region. The patient underwent surgical treatment, the histopathology being consistent with BCC. He presented recurrences of the tumor in 2009 and 2010 that were excised at approximately 9 and 16 months, respectively, from the first intervention. In 2010, the surgical procedure was radical, with removal of the tumor and the entire right superior eyelid. This approach proved to have negative side effects over the right eye in time. Therefore, after two months, a complete exenteration of the right orbit was necessary. The tumor recurred again for three times, after 20, 30 and 42 months from the first intervention and every time surgical treatment was applied. The microscopic inspection of the biopsies showed similarities between recurrences and initial tumor. In 2013, after 57 months from the first intervention, the patient was readmitted with a lesion in the same region that was excised but that time the histopathology differed from the previous, the tumor being composed of sheets of achromic epithelioid cells, with vesicular nuclei and prominent, eosinophilic nucleoli. The tumor cells were positive for pan-cytokeratin AE1∕AE3 and negative for S100 protein, human melanoma black 45 (HMB45) and vimentin that sustained the diagnosis of basosquamous carcinoma. The paper presented an interesting case with different histopathological features from a recurrence to other, with important implication in diagnosis and prognosis. The transformation of BCC into basosquamous carcinoma sustain that the basosquamous carcinoma is better a rare, aggressive variant of BCC, than an individual lesion.

Simultaneous Quantitation of Boric Acid and Calcium Fructoborate in Dietary Supplements by HPTLC-Densitometry.

The paper describes a new, simple, selective and precise high-performance thin-layer chromatographic (HPTLC) method for the simultaneous identification and quantitative determination of boric acid (BA) and calcium fructoborate (CFB) in bulk and tablet/capsule dosage forms of dietary supplements. HPTLC silica gel G 60 F254 precoated glass plates were used as the stationary phase. The mobile phase consisted of 2-propanol-water 8:2 (v/v). The two boron-based compounds were adequately separated with the Rf values of 0.83 ± 0.01 (BA) and 0.59 ± 0.01 (CFB).

Rare metastasis of renal carcinoma in the frontoethmoid-orbital region - case report and review of the literature.

A tumor located in the region of the paranasal sinuses and the orbit is not usually a metastasis, but a primary tumor. Even more, renal cell carcinoma (RCC) is very rarely the cause of metastasis in the paranasal sinuses or the orbit. Up to the present moment, few cases have been reported in the literature of such an association. The aim of the authors is to highlight the rare case of a male patient presented with ptosis, frontal swelling, minor headaches and epistaxis, as the only symptoms, but in which the mass located in the left frontoethmoidal region with extension to the orbit proved to be a RCC metastasis, thus leading to the diagnosis of the primary renal tumor. We must underline the need for clinical suspicion and the importance of accurate histopathological and immunohistochemical investigations, in such rare cases, where they are crucial in obtaining the right diagnosis.

Antimicrobial resistance development following surgical site infections.

Surgical site infections (SSIs) determine an increase in hospitalization time and antibiotic therapy costs. The aim of this study was to identify the germs involved in SSIs in patients from the Clinical Emergency County Hospital of Craiova (SCJUC) and to assess their resistance to antimicrobials, with comparisons between surgical wards and the intensive care unit (ICU). The biological samples were subjected to classical bacteriological diagnostics. Antibiotic resistance was tested by disc diffusion. We used hierarchical clustering as a method to group the isolates based upon the antibiotic resistance profile. The most prevalent bacterial species isolated were Staphylococcus aureus (S. aureus; 50.72%), followed by Escherichia coli (E. coli; 17.22%) and Pseudomonas aeruginosa; 10.05%). In addition, at lower percentages, we isolated glucose-non-fermenting, Gram-negative bacteria and other Enterobacteriaceae. The antibiotic resistance varied greatly between species; the most resistant were the non-fermenting Gram­negative rods. E. coli exhibited lower resistance to third generation cephalosporins, quinolones and carbapenems. By contrast, Klebsiella was resistant to many cephalosporins and penicillins, and to a certain extent to carbapenems due to carbapenemase production. The non-fermenting bacteria were highly resistant to antibiotics, but were generally sensitive to colistin. S. aureus was resistant to ceftriaxone (100%), penicillin (91.36%), amoxicillin/clavulanate (87.50%), amikacin (80.00%) and was sensitive to levofloxacin, doxycycline, gentamycin, tigecycline and teicoplanin. The Enterobacteriaceae resistance was only slightly higher in the ICU, particularly to carbapenems (imipenem, 31.20% in the ICU vs. 14.30% in the surgical wards; risk ratio = 2.182). As regards Staphylococcus species, but for non-fermenting bacteria, even if the median was almost the same, the antibiotic resistance index values were confined to the upper limit in the ICU. The data gathered from this study may help infection control teams to establish effective guidelines for antibiotic therapies in various surgical procedures, in order to minimize the risk of developing SSIs by the efficient application of the anti-infection armamentarium.

Chondrosarcoma of the hyoid bone: a case report.

Chondrosarcoma is a malignancy of the mesenchymal tissue derived from transformed cells that produce the cartilage matrix. In the neck area, it represents less than 0.5% of malignant tumor pathology. Chondrosarcoma of the hyoid bone is extremely rare, only 20 cases having been published so far (PubMed 2014). We present the case of a 30-year-old patient from the urban area, admitted in the ENT (Ear, Nose & Throat) Emergency Service with inspiratory dyspnea, dysphagia, stomatolalia, with evolutive and progressive clinical history of 2-3 months. Endoscopic examination revealed a pharyngolaryngeal tumor process located in the right vallecula, who by mass effect displaces the above-hyoid epiglottis. CT (computerized tomography) scan described a cervical polycystic tumor aspect, with multiple septae and inside calcifications with a diameter of 3-4 mm. Surgery consisted in removal of the tumor process together with the hyoid bone. Histopathological and especially immunohistochemical examination established the diagnosis of low-grade chondrosarcoma of the hyoid bone. For assessment of the phenotype of the tumor cells, the following immunohistochemical markers were used: p53, Ki67. The patient followed radiochemotherapic oncological treatment and returned for regular follow-ups. There was a positive development with no signs of regional or remote relapse or metastasis for 24 months after surgical treatment. Surgery is the treatment of choice, with complete removal of the tumor, with chemoradiation playing an adjuvant role. Regular tracking of the patient is mandatory.
