Abstract Background India accounts for 20% of the global retinoblastoma (RB) burden. However, the existing data on RB1 gene germline mutations and its influence on clinical decisions is minimally explored. Methods Fifty children with RB underwent complete clinical examination and appropriate multidisciplinary management. Screening of germline RB1 gene mutations was performed through next-generation sequencing and Multiplex Ligation-dependent Probe Amplification (MLPA) analysis. The mutation and non-mutation groups were compared for clinical parameters especially severity, progression and recurrence. Results Twenty-nine patients had bilateral RB (BLRB) and 21 had unilateral RB (ULRB). The genetic analysis revealed 20 RB1 variations in 29 probands, inclusive of 3 novel mutations, known 16 mutations and heterozygous whole gene deletions. The mutation detection rate (MDR) was 86.2% in BLRB and 19% in ULRB. Associations of disease recurrence (p = 0.021), progression (p = 0.000) and higher percentage of optic nerve invasion, subretinal seeds and high-risk pathological factors were observed in the mutation group. Clinical management was influenced by the presence of germline mutations, particularly while deciding on enucleation, frequency of periodic follow up and radiotherapy. Conclusions We identified novel RB1 mutations, and our mutation detection rate was on par with the previous global studies. In our study, genetic results influenced clinical management and we suggest that it should be an essential and integral component of RB-care in India and elsewhere.

Thyroid cancer is a complex disease requiring management by a large multidisciplinary team. The number of patients with a diagnosis of thyroid cancer is significantly increasing year-on-year, and traditional models of consultant-led follow up are no longer sustainable. Although nurse-led cancer follow-up clinics are becomining increasingly common, thyroid cancer nurse-led follow-up clinics are rare. An excellent understanding of the disease, treatment and management of risk of disease recurrence is essential for safe patient care, and is discussed in this article. The clinic discussed uses the skill set of head and neck nurse specialists, including psychological support, coping strategies for long-term side effects of treatment and non-medical prescribing. A patient survey of the service revealed high levels of patient satisfaction and a desire to continue face-to-face consultations rather than telephone clinics.

Purpose To determine the effect of estrogen replacement therapy (ERT) on recurrence rate and survival in women who have undergone surgery for stage I or II endometrial cancer. Patients and Methods After surgery, eligible patients were allocated to therapy with ERT or placebo after undergoing hysterectomy with or without pelvic and aortic nodal sampling. Planned duration of hormonal versus placebo treatment was 3 years, with an additional 2 years of follow-up. Results The median follow-up time for all 1,236 eligible and assessable patients was 35.7 months. Stage, grade, histologic subtype, and percentage of patients receiving adjuvant therapy were similarly distributed between the groups. The median age at diagnosis for the 618 patients randomly assigned to ERT was 57 years (range, 26 to 91 years). Two hundred fifty-one patients (41.1%) were compliant with ERT for the entire treatment period. Disease recurrence was experienced in 14 patients (2.3%). Eight patients (1.3%) developed a new malignancy. There were 26 deaths (4.2%), and five deaths (0.8%) were a result of endometrial cancer. The median age at diagnosis for the 618 patients in the placebo group was 57 years (range, 30 to 88 years). Twelve patients (1.9%) experienced disease recurrence. Ten patients (1.6%) developed a new malignancy. There were 9 deaths (3.1%) in the placebo group, and four deaths (0.6%) were a result of endometrial cancer. Conclusion Although this incomplete study cannot conclusively refute or support the safety of exogenous estrogen with regard to risk of endometrial recurrence, it is noteworthy that the absolute recurrence rate (2.1%) and the incidence of new malignancy were low.

Abstract Background Chordomas are the most common primary spinal column malignancy in the United States. The aim of this study was to determine whether chordomas may be detected by evaluating mutations in circulating tumor DNA (ctDNA). Methods 32 patients with a biopsy-confirmed diagnosis of chordoma had blood drawn pre-operatively and/or at follow up appointments. Mutations in the primary tumor were identified by whole exome sequencing and liquid biopsy by ddPCR and/or RACE-Seq was used to detect one or more of these mutations in plasma ctDNA at concurrent or later time points. Results 87.1% of patients were ctDNA positive at the time of initial blood draw (p < 0.001). Follow up blood draws in twenty of the patients suggest that ctDNA levels may reflect the clinical status of the disease. Patients with positive ctDNA levels were more likely to have greater mutant allele frequencies in their primary tumors (p = 0.004) and undergo radiotherapy (p = 0.02), and the presence of ctDNA may correlate with response to systemic chemotherapy and/or disease recurrence. Conclusions Detection of ctDNA mutations may allow for the detection and monitoring of disease progression for chordomas.

Introduction: Early during the COVID-19 pandemic, the royal college of surgeons advised to use Non-Operative Treatment of appendicitis NOTA or otherwise open surgery for appendicitis. This study has explored the resulted management differences, and the outcome after one year follow up. Methods: Retrospective study covering Pre-pandemic data over March-May,2019 & COVID-19 pandemic data over March-May,2020. We compared the outcome of non-operative treatment approach (NOTA), open and laparoscopic surgical outcome between the 2 groups. Results: The number of admissions was lower in the COVID compared to the Pre-COVID Group (35 vs 43). In the COVID group had more CT scanning of the abdomen and pelvis (65.7% vs 42.2%; p=0.036). There was no difference in the diagnostic value for these imaging methods between the 2 groups (87.5% vs 86.6%) During COVID period Signicantly fewer patients underwent surgery (77.1 vs 92.8; p<0.04), There were signicantly more complicated appendicitis cases in the COVID group compared to Pre-COVID group (59.2 vs 28.2; p:0.021). There was in reduction LOS when comparing Laparoscopic to NOTA (1.7 vs 2.6 days; p:0.03). There has been higher complication rate in the open and NOTA treatments compared to Laparoscopic, but this was not statistically signicant (24.3 % vs 14.8%; p: 0.29). In the NOTA group 41 % of the patients had emergency or interval appendectomy in after one year follow up period. Conclusions: There was a tendency towards conservative approach/open surgery during the pandemic. Our study suggests that Laparoscopic surgery should remain the preferred method of management of appendicitis during COVID-19 pandemic considering the more complicated appendicitis. NOTA should be limited to selected high risk patients. accepting the risk of disease recurrence and need for further interval or emergency surgery

Aim of the study: Urge incontinence is considered to be a dysfunctional pathology of social interest due to the psychological and relational implications of such disability, the elevated number of affected patients and the consequent treatment costs. We propose an innovative non-pharmacological and non-invasive care methodology: Frequency rhythmic electrical modulation system (F.R.E.M.S.) therapy (FT), based on the administration of electric fields of monophasic pulsed, negative, asymmetric current, generated by a neurostimulator with the characteristics of low variable frequency, high voltage and very low impulse duration. Material and Methods: 30 patients were studied with urodynamic evaluation and radiological diagnostic techniques, and underwent 2 cycles of 15 days therapy, with a 12 months follow-up. Results: In 93% of cases, we obtained a positive result, with either disappearance or improvement of symptoms. Conclusion: Although the Authors believe that clinical results deserve further neurohistological and immunohistochemical studies, in order to define the anathomophysiological and biochemical changes induced by FT, they propose it as a possible alternative to traditional pharmacological therapy and electrical stimulation.

The urachus is a tubular structure that connects the bladder to the allantois in the embryonic development, involuting after the third trimester. The urachus carcinoma is an extremely rare tumor that accounts for <1% of all bladder cancers. We report a case of a 46-year-old woman, with no past medical history, complaining of hematuria with 6-month duration and a physical exam and an abdominal computed topographic scan revealing an exophytic mass of 6.8 cm longer axis that grew depending on the anterior bladder wall, invading the anterior abdominal wall. Cystoscopy detected mucosal erosion. The biopsy showed structures of adenocarcinoma of enteric type. The surgical specimen showed urachus adenocarcinoma of enteric type with stage IVA in the Sheldon system and stage III in the Mayo system. This case has a 3-year follow-up without disease recurrence.

<p class="abstract"><span lang="EN-US">Severe periodontal disease often leads to tooth loss, necessitating prosthetic rehabilitation to restore function and aesthetics. The concept of perio-prosthetic treatment using extensive bridges of cross-arch design was introduced approximately 30 years ago. Long term follow-up studies have shown that teeth with reduced periodontal support can be used as abutments for extensive fixed prostheses, provided periodontal disease had been treated successfully and an effective recall program had been instituted to prevent periodontal disease recurrence. Implants along with cross arch bridges in controlled periodontitis subject have never been used together for complete full mouth rehabilitation.</span></p>

Today, the late diagnosis of cancers is a big challenge, and using novel diagnostic techniques will provide essential, faster and more accurate treatments. Unfortunately, existing common and traditional diagnostic methods have not been helpful completely and most cancers are diagnosed too late. Recently, researchers have found new diagnostic methods against cancers by aptasensors; these sensory systems can detect involved biomarkers in various cancers so that the research in this field is continued strictly. Aptasensors can detect cancer markers in small quantities and high selectivity; moreover, other advantages of cancer aptasensors such as optimized time and cost saving can be considered. In addition, the aptasensors have been used in the diagnosis of the effective and related factors in cancer therapy follow-up. Here, the most researches about cancer aptasensors and other involved markers were collected, reviewed and described.

Duodenal Neuroendocrine Tumours

Background: Duodenal neuroendocrine tumours (D-NETs) are rare but increasingly diagnosed. This study aimed to assess the overall survival and recurrence rate among patients treated for D-NETs. Methods: Patients with D-NETs were retrospectively reviewed with a median follow-up time of 4.8 years (range 0.0–17.2 years). Results: A total of 32 patients with median age 68.0 years were identified. Fifteen patients underwent surgery while ten patients underwent endoscopic treatment. Mean estimated overall survival for the entire population was 12.1 years (95% CI 9.5–14.7 years), while 5-year overall survival was 81.3%. Tumour grade G1 was associated with longer mean estimated survival compared to G2 tumours (13.2 years versus 4.4 years, p = 0.010). None of the 23 patients who underwent presumed radical endoscopic or surgical resection had disease recurrence during follow-up. Tumours <10 mm could be treated endoscopically whereas a high proportion of patients with tumours 10–20 mm should be considered for surgery. Conclusion: Patients with D-NETs had long overall survival, and mortality was more influenced by other diseases. Both endoscopic and surgical resections were effective as no recurrences were diagnosed during follow-up.
