For the estimation of short-term prognosis in terminal cancer patients, it is important to establish a prognostic index that does not involve blood tests. We compared the prognostic ability of the Barthel Index (BI) with the Glasgow Prognostic Score (GPS). Ninety-seven inpatients with terminal cancer at Onomichi Municipal Hospital who died between 2018 and 2019 were retrospectively analyzed. The sensitivity, specificity, accuracy, and area under the receiver operating characteristic curve (AUROC) were compared between the BI and GPS. For predicting the 15 day prognosis, the BI showed higher specificity, accuracy, and AUROC than the GPS. For predicting the 30 day prognosis, the BI showed higher sensitivity, accuracy, and AUROC than the GPS. The BI can predict the 15 or 30 day prognosis in terminal cancer patients. As the BI does not require blood tests, it may be an option for prognostic prediction in terminal cancer patients. Full article

As the potent, selective Fms-Like Tyrosine Kinase 3 (FLT3) inhibitor gilteritinib has only been approved for use for a few years, its efficacy and complications remain incompletely understood. We herein report an elderly patient with FLT3 internal tandem duplications (FLT3-ITD) mutated acute myeloid leukemia (AML) who developed natural killer cell large granular lymphocytes (NK-LGL) in the bone marrow and peripheral blood during gilteritinib treatment. Case: A 79-year-old Japanese female had been diagnosed with FLT3-ITD-mutated AML. The patient received hydroxycarbamide 2000 mg daily for induction chemotherapy but did not achieve remission at day 28 postinduction. The treatment was then changed to gilteritinib 120 mg daily. Although the reduction of blasts in peripheral blood occurred immediately, it was revealed abnormal lymphocytes with large granules developed in bone marrow and peripheral blood. These lymphocytes were analyzed by flow cytometry, which revealed that these cells were NK-LGL because they expressed CD2, CD7, CD16, and CD56 and did not express CD3, CD19, and CD20. The patient achieved partial remission (PR) in a month with gilteritinib treatment. Leukemia eventually could not be controlled, but PR persisted for about 4 months and leukemia was controlled for 4 months after progression disease (PD) with gilteritinib treatment alone. Conclusion: Gilteritinib may induce the NK-LGL. The exact mechanism and effect of LGL in patients with FLT3 mutated AML treated with gilteritinib warrants further investigation. Full article

Cross-reactivity occurs when antibodies formed against an antigen have amino acid sequence homology with another target protein. This allows antibodies formed against the antigen to also bind to similar proteins that share structural similarity. Autoimmune reactions to gluten can lead to sporadic ataxia in susceptible genotypes due to cross-reactivity. With gluten ataxia, dietary consumption of gluten proteins induce immunological cross-reactivity with glutamic-acid decarboxylase-65 (GAD-65) target proteins found in the cerebellum. Implementation of a strict gluten-free diet has been shown to improve the expression of this form of ataxia with most patients in this subgroup. However, there are some subjects that have limited clinical responses to only a strict gluten-free diet. Dietary protein cross-reactivity to other food proteins, besides gluten, that also share structural similarity to GAD-65 may also play a role in this reaction. In this case report, we report of a patient suffering from gluten-ataxia in which a gluten-free diet alone did not generate significant clinical outcomes until other foods that cross-react with GAD-65 were also removed from their diet.

The nasopharyngeal swab is commonly used for the diagnosis of SARS-CoV-2 infection. Since the swab is performed in this site, of course, it cannot detect the presence of the virus in other tissue districts such as the lung, brain, or bowel. In the present case report, the nasopharyngeal swab was negative twice. From this, the patient discontinued antiviral therapy. Nasopharyngeal swabs were maintained negative until five days later, when we recorded a severe impairment of the patient’s clinical condition. At this time, the bronchoalveolar lavage was positive for SARS-CoV-2. The purpose of the case herein described is to suggest paying attention to the nasopharyngeal swab result. A negative detection in nasopharyngeal swab could not be indicative of COVID-19 recovery. Full article

Isolated adrenal metastasis of breast cancer is very rare, so adrenalectomy for breast cancer metastasis is rarely performed. The case of a breast cancer patient with five-year survival after resection of a left isolated adrenal metastasis is presented. A 70-year-old woman underwent left modified radical mastectomy and axillary lymphadenectomy for invasive ductal carcinoma (T2N1M0) 9 years earlier. At regular follow-up, a left adrenal mass, 4 cm in diameter, was seen on ultrasound examination and computed tomography (CT). Endoscopic adrenalectomy was performed. Pathological examination confirmed isolated adrenal metastasis of breast cancer. After surgery, hormone therapy was given for 5 years. Ten years after adrenalectomy, no metastatic lesions in other organs have been found on CT. Adrenalectomy for a metastatic adrenal tumor of breast cancer may provide survival benefits when combined with systemic hormone therapy and chemotherapy, particularly in patients with disease confined to the adrenal glands.

Background: To establish if an allergy towards all β-blockers, as a group, should be assumed, if an allergic reaction is observed while using one specific β-blocking agent. Case presentation: The non-selective β-blocker timolol caused a severe allergic ocular reaction in a non-atopic patient with advanced primary open-angle glaucoma. Results: A patch test confirmed timolol allergy. No allergic reaction to other anti-glaucomatous topical drugs was observed, and treatment with the selective β-blocker betaxolol was successfully initiated. Conclusion: Allergy to the non-selective β-blocker timolol does not necessarily predict allergy to the selective β-blocker betaxolol, and betaxolol should therefore not be excluded as an alternative treatment.

Breast cancer is the most frequent cancer diagnosed in women in the world regardless of race or ethnicity. About 10% of invasive breast carcinomas are lobular subtype. The loss of the E-caderin expression that occurs in lobular carcinoma leads to a higher risk of metastases in membranes (meningeal, pleural, peritoneum) and gastrointestinal and/or endobronchial mucous, which may lead to several odd symptomatology. We report a 79 years old female patient with lobular breast cancer associated to CDH1 germline mutation. She was diagnosed with breast cancer in December 2016 after noticing a right-armpit nodule whose pathological examination demonstrated an immunohistochemistry profile compatible with lobular breast carcinoma metastasis and had estrogen receptors 98%, progesterone receptors < 1%, ki67 25%, negative her2 score. Family history of only one paternal uncle with stomach cancer. After two lines of hormone therapy, she had disease progression and started oral chemotherapy with capecitabine. In a few weeks, the patient had refractory diarrhea. At the beginning, it was defined like colitis chemotherapy related. However, the clinical features showed necessity of further investigation. Then, she was diagnosed with CDH1 germline mutation after massive progression at gastrointestinal mucous. This case made possible to inform the family about risk of germline mutation and necessity of genetic counseling. Full article

Drug-related hospital admissions are common, and up to 25% of patients presenting to emergency departments with injuries test positive for alcohol and drug use. This case reports on a 55-year-old male who attended the emergency department (ED) at the Royal United Hospital, Bath, UK. He presented after sustaining significant soft tissue trauma to his tongue, following recreational drug use of an unknown substance. His injuries included the amputation and loss of the anterior third of his tongue, having suffered a bite from another individual. This unusual case describes the patient’s injuries and subsequent management, both in the emergency department and during follow-up. This case will be of benefit to clinicians from many disciplines including dentists, oral and maxillofacial surgeons, ENT surgeons and speech and language therapists. Full article

Both benign and malignant conditions related to regional or systemic disorders could be included in the differential diagnosis of bilateral breast edema. Some of them are often unilateral, including stromal infiltration and lymphatic obstruction presented in “peau d’ orange”, which is the usual presentation of breast cancer. However, the term “idiopathic” could be included in the spectrum of diagnoses. Here, we present a woman of 78 years old who came into our breast unit with a bilateral, painless edema of the breasts (appeared one month ago). Clinical examination revealed that both breasts were swollen with widespread erythema and the appearance of an orange peel/“peau d’ orange”. On palpation, the breasts were not sensitive, and no tumor was palpable. However, clinically palpable lymph nodes were found in both axillas. Her temperature was normal. The breast edema could not be explained from her medical history nor the medications taken. Breast ultrasound, Mammography and Magnetic Resonance Imaging were non-conclusive (BI-RADS 0) and bilateral core biopsy was negative for cancer. Anti-inflammatory plus antibiotic therapy was prescribed for 10 days and at the end of treatment, regional redness and edema were disappeared and reduced, respectively. Total recovery was found one month after the initial findings. It can be concluded that bilateral breast edema is correlated to regional or systemic conditions or it is presented as an “idiopathic” disorder of unknown etiology. Full article
