PURPOSE
Primary oral mucosal melanoma (OMM) is a rare neoplasm accounting for the 0.2% to 0.8% of all melanomas. The aim of the present manuscript is (1) to describe 2 cases of primary OMM treated at our department, and (2) to perform a systematic literature review on primary OMM occurrence and treatment.
METHODS
Two cases of primary OMM were described. A systematic review is presented in order to assess the treatment options, recurrence, metastasis development, and survival rate of primary OMM.
RESULTS
Two patients were referred for the development of a lesion of the hard palate and the maxillary gingival mucosa, respectively. An incisional biopsy was performed in both patients, followed by extensive surgical resection after a thorough consideration of patient history and systemic involvement. The literature search retrieved 447 primary OMM cases. In the 30% of cases, distant metastases were already present at the time of diagnosis. The management of primary OMM most frequently involved surgical treatment and adjuvant radiotherapy.
CONCLUSIONS
Primary OMM still represents a challenge for the clinician, as the diagnosis is often performed when metastases have already developed. The prognosis is generally poor, thus highlighting the need for further investigations to improve early diagnosis.

Review
The microbiome is vital for the proper function of the gastrointestinal tract (GIT) and the maintenance of overall wellbeing. Gut ischemia may lead to disruption of the intestinal mucosal barrier, resulting in bacterial translocation. In this systematic review, according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) guidelines, we constructed a search query using the PICOT (Patient, Intervention, Comparison, Outcome, Time) framework. Eligible studies reported in PubMed, up to April 2021 were selected, from which, 57 publications' data were included. According to these, escape of intraluminal potentially harmful factors into the systemic circulation and their transmission to distant organs and tissues, in utero, at birth, or immediately after, can be caused by reduced blood oxygenation. Various factors are involved in this situation. The GIT is a target organ, with high sensitivity to ischemia-hypoxia, and even short periods of ischemia may cause significant local tissue damage. Fetal hypoxia and perinatal asphyxia reduce bowel motility, especially in preterm neonates. Despite the fact that microbiome arouse the interest of scientists in recent decades, the pathophysiologic patterns which mediate in perinatal hypoxia/asphyxia conditions and gut function have not yet been well understood.

Review
BACKGROUND
In addition to conditioning measures in liver surgery, perioperative anti-tumor therapy is becoming increasingly more important in cholangiocarcinoma (CCA).
OBJECTIVE
Systematic literature review on the status of multimodal and in particular neoadjuvant therapy for CCA.
MATERIAL AND METHODS
Literature overview of the current scientific original and review articles.
RESULTS
Resection and rarely also liver transplantation are still the only curative treatment approaches for CCA in the non-distant metastatic stage; however, long-term results, e.g. in node positive tumors, are still unsatisfactory. Adjuvant chemotherapy is now standard but cannot be used in many patients. Neoadjuvant concepts include chemotherapy and local and locoregional procedures, such as radioembolization. Both are increasingly used in intrahepatic CCA (iCCA) but rarely in perihilar CCA. Initial data show that this is very effective in iCCA to achieve secondary operability in primarily inoperable cases. In addition, based on the current literature, neoadjuvant therapy also seems justified in operable intrahepatic CCA with a high risk of recurrence (e.g. lymph node metastases).
CONCLUSION
There is a high potential for the use of multimodal therapy in CCA, which could further increase in the near future as a result of new therapeutic agents. Due to the lack of evidence clear recommendations cannot be given; however, it is becoming apparent that neoadjuvant therapy is gaining importance in iCCA and is already increasingly used as part of individual concepts in patients with a high risk of recurrence.

Review
(1) Background: Anal canal adenocarcinomas constitute 1% of all gastrointestinal tract cancers. There is a current lack of consensus and NICE guidelines in the United Kingdom regarding the management of this disease. The overall objective was to perform a systematic review on the multitude of practice and subsequent outcomes in this group. (2) Methods: The MEDLINE, EMBASE, EMCARE and CINAHL databases were interrogated between 2011 to 2021. PRISMA guidelines were used to select relevant studies. The primary outcome measure was 5-year overall survival (OS). Secondary outcome measures included both local recurrences (LR) and distant metastases (DM). The Newcastle-Ottawa Scale (NOS) was used to assess the quality of studies retrieved. The study was registered on PROSPERO (338286). (3) Results: Fifteen studies were included. Overall, there were 11,967 participants who were demographically matched. There were 2090 subjects in the largest study and five subjects in the smallest study. Treatment modalities varied from neoadjuvant chemoradiotherapy (CRT), CRT and surgery (CRT + S), surgery then CRT (S + CRT) and surgery only (S). Five-year OS ranged from 30.2% to 91% across the literature. LR rates ranged from 22% to 29%; DM ranged from 6% to 60%. Study heterogeneity precluded meta-analysis. (4) Conclusions: Trimodality treatment with neoadjuvant chemoradiotherapy (CRT) followed by radical surgery of abdominoperineal excision of rectum (APER) appeared to be the most effective approach, giving the best survival outcomes according to the current data.

OBJECTIVES
Occult breast cancer (OBC) is a rare malignant breast tumor. Because of the rare cases and limited clinical experience, a huge therapeutic difference has existed all over the world and standardized treatments have yet been established.
METHODS
A meta-analysis was conducted using MEDLINE and Embase databases to identify the choice of OBC surgical procedures in all studies: (1) patients undergoing axillary lymph node dissection (ALND) or sentinel lymph node biopsy (SLNB) only; (2) patients undergoing ALND with radiotherapy (RT); (3) patients undergoing ALND with breast surgery (BS); (4) patients undergoing ALND with RT and BS; and (5) patients undergoing observation or RT only. The primary endpoints were mortality rates, the second endpoints were distant metastasis and locoregional recurrence.
RESULTS
Among the 3,476 patients, 493 (14.2%) undergo ALND or SLNB only; 632 (18.2%) undergo ALND with RT; 1483 (42.7%) undergo ALND with BS; 467 (13.4%) undergo ALND RT and BS, and 401 (11.5%) undergo observation or RT only. After comparing the multiple groups, both groups 1 and 3 have higher mortality rates than group 4 (30.7% vs. 18.6%, p < 0.0001; 25.1% vs. 18.6%, p = 0.007), and group 1 has higher mortality rates than groups 2 and 3 (30.7% vs.14.7%, p < 0.00001; 30.7 vs. 19.4%, p < 0.0001). Group (1 + 3) had a prognosis advantage over group 5 (21.4% vs. 31.0%, p < 0.00001). There was no significant difference both in the distant recurrence rates and locoregional rates between group (1 + 3) and group (2 + 4) (21.0% vs. 9.7%, p = 0.06; 12.3% vs. 6.5%, p = 0.26).
CONCLUSION
On the basis of this meta-analysis, our study indicates that BS including modified radical mastectomy (MRM) and breast-conserving surgery (BCS) combined RT may appear as the optimal surgical approach in patients with OBC. RT cannot prolong both the time of distant metastasis and the local recurrences.

Review
Data describing features and management of oropharyngeal neuroendocrine carcinomas (NEC) remain sparse. A systematic review was performed. Patients were stratified by treatment modality and examined for disease progression and survival outcomes. Ninety-four patients from 50 publications were included. Average age at diagnosis was 59.7 years (range 14-83). 73.4% were male. Most studies did not document HPV status. Forty patients (85.1%) were p16 positive, and 34 (85.0%) were HPV-ISH positive. Overall survival was 75.4% at 1 year, and 40.0% at 2 years. Of patients with locoregional disease, 33.8% developed distant metastasis. 12.5% of patients developed locoregional recurrence. Patients who developed distant metastases had worse overall survival (p = 0.0004). No significant difference was found between treatment modalities. Human papilloma virus may be associated with oropharyngeal NEC. Current treatments provide locoregional control, but distant metastases are common and confer low overall survival.

Review
OBJECTIVE
Body piercing is defined as the penetration of jewellery into openings made in different body areas. In the last decades, it has become increasingly common in the general population. The aim is to analyse the available literature about complications from body piercing for contributing to raise the awareness towards this issue and to plan and perform appropriate prevention interventions.
STUDY DESIGN
This is a systematic review.
METHODS
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used to perform this systematic review; the protocol was registered with PROSPERO [CRD42020177972]. PubMed, Scopus and Web of Science were searched from database inception to April 2020, and articles in English language reporting a proven association between piercings and health risks were included, and their quality were assessed by adequate quality assessment tools.
RESULTS
A total of 4748 studies were found, and after duplicates removal and screening, 84 articles were included. Studies dealing with microbiological effects reported these complications both locally and at distant sites as a result of the spreading of the primary site infection: mastitis, endocarditis, glomerulonephritis, cephalic tetanus, viral hepatitis, HIV, cerebellar brain abscess and toxic shock syndrome. In addition, bleeding, gingival recession, dental injuries, contact dermatitis, granulomatous dermatitis, keloid, fibroma and basal cell carcinoma were reported.
CONCLUSIONS
Health authorities should promote educational campaigns to spread the knowledge on health risks related to piercings. Besides, piercers are often not adequately aware of all the possible adverse effects due to piercings because their professional training differs among countries. It is therefore advisable to provide periodical upgrade of their education in this field.

Review
Although papillary thyroid carcinoma (PTC) is considered to have an excellent prognosis, some recently identified more aggressive variants show reduced overall survival rates. Hobnail PTC (HPTC) was newly recognized as one of these aggressive forms, affecting recurrence, metastasis, and overall survival rates. Herein, we performed a systematic review and meta-analysis of studies including cases or case series with patients with HPTC. Furthermore, we included our individual case series consisting of six patients. The pooled mortality rate in the cohort, consisting of 290 patients, was 3.57 (95% CI 1.67−7.65) per 100 person/years. No sex differences could be observed concerning mortality (p = 0.62), but older age and tumor size significantly affected mortality (p = 0.004 and p = 0.02, respectively). The percentage of hobnail cells did not affect mortality (p = 0.97), neither did the presence of BRAF mutations. Classical characteristics such as the presence of extrathyroidal extension (p = 0.001), distant metastases (p < 0.001), and lymph node metastases (p < 0.001) all had a significant impact on mortality. Thus, HPTC appears to correlate with worse overall survival, and all PTC cases should be carefully assessed for this variant.

Journal of Gynecology Obstetrics and... Dec 2022We performed a systematic review in order to describe the clinical presentation, therapeutic management and outcomes of malignant myoepitelioma of the breast.
OBJECTIVES
We performed a systematic review in order to describe the clinical presentation, therapeutic management and outcomes of malignant myoepitelioma of the breast.
SEARCH STRATEGY
A systematic search of MEDLINE and EMBASE references from January 1980 to Marsh 2020 was performed. We included articles that reported cases of malignant breast myoepithelioma. Data from eligible studies were independently extracted onto standardized forms by two reviewers.
RESULTS
31 articles including 47 cases of malignant breast myoepithelioma and 3 other unpublished cases managed in our establishment were included in this systematic review. The average age at diagnosis was 60.7 years old [range 30-81]. The average size of the tumor was 46mm [range 10 -230]. 30 patients had a partial mastectomy and 18 a total mastectomy. Only 15% of patient (7/48) had an axillary sentinel lymph node biopsy of whom one was positive. 33% of patients (16/48) had an axillary lymph node dissection which was positive for one patient. 19% (n=9) had adjuvant radiotherapy and 15% (n=7) had adjuvant chemotherapy. 33% (n=10) of patients with partial mastectomy had at least one recurrence, versus 5.5% (n=1) after a total mastectomy. The average time between the diagnosis and the first recurrence was 25.4 months [range: 1-50]. 64% (n=7) had a second partial mastectomy and only 18% (n=2) had a total mastectomy. 27% of patient had chemotherapy after their first recurrence and 27% had radiotherapy if it was not received in first line treatment. 40% (n=4/10) of patients with partial mastectomy who recurred have had at least 2 breast recurrences. 28% (n=14) of all patients had distant metastases. 20% of patients (n=10) died whose 80% (n=8) had distant metastatic disease.
CONCLUSIONS
This systematic review provided a precise summary of the clinical characteristics and treatment of patients presenting with Malignant breast myoepithelioma in the past 40 years. We anticipate that these results will help inform current investigations and treatment.

Review
Horizontal glottectomy (HG) is a particular type of partial laryngectomy indicated for exclusive glottic tumor with anterior commissure involvement. The purpose of this study is to systematically review the literature about functional and oncological outcome of HG. This systematic review adhered to the recommendations of the PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analysis) 2009 guidelines. Articles mentioning patients undergoing HG for laryngeal squamous cell carcinoma were included. A total of 14 articles were selected and reviewed from 19 identified. The whole study population consisted of 420 patients who underwent HG. Three hundred and thirty-nine patients out of 359 were staged as T1. The range of post-operative follow-up was 5 months to 10 years. Fifty-five recurrences were experienced, being local, regional and distant in 35, 12 and 8 patients, respectively. Laryngeal preservation rate was 93.6%. Nasogastrict tube was removed on average after 10.1 days. The tracheostomy was maintained for 11.3 days. Mean hospitalization lasted for 11.7 days. According to the results of this systematic review, HG is an oncologically safe surgical option for T1a-T1b glottic tumors with oncological outcomes comparable to other treatment. HG could be a good therapeutical choice whenever poor laryngeal exposure and/or patient's refusal of radiotherapy are encountered, or when patient's medical history represents a contraindication for radiation therapy.
