Objective To evaluate the treatment outcomes of patients with Differentiated thyroid cancer (DTC) who underwent total thyroidectomy followed by RAI therapy at the Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC) in Oman. Methods This is a retrospective observational clinical study conducted at SQCCCRC. The study included all patients diagnosed with DTC who were admitted to SQCCCRC between June 2021 and November 2023. A total of 255 patients were identified and met the inclusion criteria for this study. Results The mean age at diagnosis was 39.9 ± 12.4 years (range: 14–79), with 78% of patients being female. The mean BMI was 30.3 ± 6.4 kg/m², with nearly half of the cohort (48.2%) classified as obese (BMI ≥ 30). Most patients had papillary thyroid carcinoma (92.9%), while follicular and Hürthle cell carcinoma accounted for 5.9% and 0.8% of cases, respectively. Based on the American Joint Committee on Cancer (AJCC) staging, 86.3% of the patients were classified as stage I and 3.9% as stage II. Six patients (2.4%) had stage IVB disease. According to American Thyroid Association (ATA) risk stratification the majority were low-risk. Patient age was strongly associated with disease stage. The distribution of metastatic cases varied by region, with the highest proportion observed in Dhofar. Most patients (87.1%) received a single dose of radioactive iodine (RAI), with a median cumulative dose of 3.7 mCi). At six months post-treatment, 70.2% of patients had a TG level < 0.2 ng/mL. Conclusion The outcome of therapy in majority of our patients is favorable with 72% having excellent biochemical response at last follow up. None of the patients with distant metastasis achieved excellent response and a high proportion of them came from the Dhofar governorate, a targeted intervention would be of benefit. Low risk patients require special attention and may need radioactive iodine during follow up, unlike other regions and hence warrant very close follow up and further review to establish the best practice guidelines in our region.

Objective The repair of the tympanic membrane has been attempted with large variety of synthetic, homologous and autologous tissue; however, temporalis fascia and cartilage-perichondrium are used most commonly today. Study Design This is a prospective study of patients confirmed to have CSOM and operated during the years of 2012-2013 at Al Nahdha Hospital, Muscat, Sultanate of Oman. The patients were followed up postoperatively at which we compared the graft success rate and level of hearing improvement. Setting ENT clinic at Al Nahda hospital Subjects Patients who presented to the ENT clinic at Al Nahda hospital, operated in the period between 2012 and 2013, diagnosed as CSOM and meeting our inclusion criteria. Methods We compared the outcome of the repair of the tympanic membrane perforation using temporalis fascia graft versus cartilage perichondrium grafts. Results 100% of the cartilage-perichondrium group showed a successful graft uptake in comparison to 98.9% in the temporalis fascia. Our data did not show significant differences in the average air bone gap change in both groups. Conclusion Both cartilage-perichondrium and temporalis fascia provide viable autograft material. Both achieve comparable and excellent graft uptake. Completion of our study is needed to study the hearing restoration in both groups.

Lennert lymphoma (lymphoepitheloid lymphoma) is an extremely rare variant of peripheral T-cell lymphoma, not otherwise specified. Here we report a case of Lennert lymphoma diagnosed in a 57-year-old woman. She had a three-year history of waxing and waning lymphadenopathy with a rapid increase in size in the past four months before presentation. A needle biopsy and a fine needle aspiration were non-diagnostic due to extensive necrosis. The patient underwent a right neck lymph node excisional biopsy which showed the lymph node architecture was effaced by numerous and sometimes confluent clusters of epithelioid histiocytes and infiltration of small lymphocytes. Extensive necrosis was present. Immunohistochemical stains revealed a mixed population of B- and T-cells with the T-cells showing diminished T-cell markers CD3, CD5, and CD7. Flow cytometric analysis detected a small population (7% of total lymphocytes) of CD4-positive T-lymphocytes with loss of CD3, CD5, and CD7 expressions. PCR-based T-cell receptor gene rearrangement studies showed positive results (clonal peaks) in both gamma and beta genes. Stains for microorganisms were negative. The overall findings indicate Lennert lymphoma. To our knowledge, this is the first reported case of Lennert lymphoma with extensive necrosis. The patient is undergoing chemotherapy. The diagnosis of Lennert lymphoma can be challenging, particularly in cases with extensive necrosis. Our case highlights that adequate sampling is important in the investigation of patients with suspected Lennert lymphoma. A careful pathologic examination with ancillary studies including flow cytometry, immunohistochmistry, and cytogenetic and molecular studies leads to the accurate diagnosis.

In Mexico, breast cancer is the second most common site of cancer in women and in most developed and emerging countries. Incidence rates have increased in many countries, although in some, mortality has remained stable with a slight reduction. There are geographical differences with high rates of breast cancer in North America, Northern Europe and Oceania, and lower rates in Central and South America, South and East Europe; in addition to emerging countries in Africa and Asia. Genetic and hereditary factors constitute less than 5% of breast cancer cases and other risk factors for breast cancer are related to the reproductive life of the woman. This work was carried out in order to determine if the risk factors considered classic are really associated with breast cancer in our sample of Mexican women studied.

This report presents a case of collision tumors of low-grade B-cell lymphoma and poorly differentiated adenocarcinoma in the caceum of a 63-year-old woman. Lymphoma was diagnosed incidentally after appendectomy for a clinical presentation of acute appendicitis. Imaging follow-up demonstrated mesenteric lymphadenopathy and liver lesions, and all surgically resected regional mesenteric lymph nodes and liver biopsy were found to be infiltrated by both mucosa-associated lymphoid tissue (MALT) lymphoma and adenocarcinoma. Systemic chemotherapy was administered for advanced colonic adenocarcinoma with liver metastases. The occurrence of synchronous lymphoma and adenocarcinoma of the colorectal region is rare, and this is a previously unreported case of a patient that was diagnosed during management of acute appendicitis.
