Venetoclax-induced vitiligo in a patient with chronic lymphocytic leukemia.

Venetoclax, a highly selective Bcl-2 inhibitor, is an orally bioavailable drug that has been approved as first-line therapy for chronic lymphocytic leukemia (CLL) in combination with obinutuzumab, as well as monotherapy in the setting of relapsed CLL. Although some of its life-threatening side effects are well known, including tumor lysis syndrome and cytopenias, others less known side effects include skin reactions. Skin rash is commonly reported in literature, which is often mild and not life-threatening. In this case report, the authors describe what is potentially the second case of venetoclax-induced vitiligo reported in literature. A 77-year-old man with CLL Rai stage II with cytogenetics showed 11 q23 deletion in 14% of cells, and 14q32 partial deletion in 9% of cells developed vitiligo in his extremities 2 years into treatment. A decision was made to continue venetoclax with close monitoring as the side effect was mild and not debilitating. The patient continued to do well. Although vitiligo is not associated with increased mortality risk, its development is associated with increased psychological stress. The mechanism by which vitiligo develops remains unclear. There may be an association between drug-induced vitiligo and improved cancer prognosis; however, larger studies need to be carried out to prove this hypothesis.

Three Cases of Lenalidomide Therapy for Multiple Myeloma and Subsequent Development of Secondary B-ALL.

INTRODUCTION: Multiple myeloma (MM) is the second most common hematological malignancy, accounting for 1% of all cancers, with median age of diagnosis between 66-70 years. MM remains incurable despite advances in treatment over time. Lenalidomide is an important medication used in induction therapy for MM and is also used for maintenance therapy for standard risk patients. With its increasing use, data is emerging about its use being associated with increased risk of secondary primary malignancies (SPM), especially when used as maintenance therapy. CASE SERIES: In this case series, we describe three patients with refractory MM treated with lenalidomide maintenance who later developed sALL. All had a common presentation of pancytopenia. They developed cytopenias while being on lenalidomide which was refractory to lenalidomide cessation, prompting bone marrow biopsy. MANAGEMENT AND OUTCOME: Lenalidomide was subsequently stopped, and patients were treated for secondary B-ALL. However, all passed away either due to relapse of disease or complications arising from treatment. DISCUSSION: The mechanism of lenalidomide associated SPMs is not well understood however its incidence is well documented. At least 13 cases of ALL (predominantly B-cell ALL) following Immunomodulator imide drugs (IMiDs) have been reported in literature. An analysis of a larger cohort of patients is required to determine causality of lenalidomide with sALL. However, benefits of maintenance lenalidomide in patients with MM outweighs the risk of developing SPMs. Albeit persistent pancytopenia on lenalidomide therapy should be evaluated with bone marrow biopsy since it could be caused by secondary B -cell ALL.

The influence of operation theatre environment on patients' perceptions during awake procedures: a cross-sectional study.

OBJECTIVE: To determine the perceptions of patients regarding operation theatre conversation and environment during an awake procedure. METHODS: The descriptive, cross-sectional study was conducted from February to August 2017 in postoperative wards of Military Hospital, Rawalpindi, Pakistan, and comprised women undergoing gynaecological or obstetric procedures under regional anaesthesia. Closedended questionnaires were distributed via nonprobability convenient sampling. Operation theatre data was collected from the anaesthesia notes, and data was analysed using SPSS 22. RESULTS: There were 93 female subjects with a mean age of 28.23}5.42 years (range: 19-48 years). Overall, 90(96.8%) subjects regarded the conduct of operation theatre staff as cooperative and friendly with 64(68.8%) viewing the conversation among the staff as helpful in relieving anxiety. The thought of anaesthesia waning caused anxiety in 40(43%) subjects, but there was no difference in perceived anxiety between those counselled 61(65%) and not counselled by the anaesthetist. With regards to the environment, 41(44%) subjects said more measures were required to prevent patients from seeing the operating field. Besides, 30(32.2%) and 20(21%)subjects had reservations regarding the presence of male staff and medical students respectively. The opinion regarding medical professionals did not change for 60(64%) subjects after the procedure, and 37(39.8%) recommended that communication skills of medical professional needed improvement. CONCLUSIONS: The environment in the theatre can have an influence on the patient's anxiety levels. Counselling by surgeons, casual conversations in the theatre can help alleviate apprehensions of the patients.

Testicular Plasmacytoma Masking as Epididymo-orchitis in a Known Multiple Myeloma Patient.

BACKGROUND/AIM: Extramedullary plasmacytoma (EMP) is defined as a localized plasma cell neoplasm that arises in tissues other than the bone. The most common sites of involvement of EMP are the upper airways followed by lymph nodes, gastrointestinal tract, thyroid gland, skin, brain, liver, and lungs. Testicular plasmacytoma has a very rare occurrence with about 70 cases reported in literature to date. CASE REPORT: We describe a 52-year-old-male with a diagnosis of multiple myeloma presenting with lytic lesions of the axial skeleton. He had lambda light chain restricted, R-ISS stage II with high risk cytogenetics as he tested positive for t(4;14). He underwent four cycles of cyclophosphamide, bortezomib and dexamethasone followed by auto-peripheral stem cell transplantation. He was kept on ixazomib, lenalidomide and dexamethasone maintenance therapy, but relapsed soon after and was diagnosed with plasmacytoma of the left lung. Therapy was switched to daratumumab, carfilzomib and dexamethasone and the patient received radiation of his left lung. He then developed left painless testicular mass which was treated with six weeks course of antibiotics. However due to persistence of concerning features on scrotal ultrasound post-treatment, the patient underwent radical orchiectomy with pathology coming back positive for plasma cells. CONCLUSION: The testes serve as a sanctuary site for hematological malignancies due to the presence of the testicular-blood barrier. Hence, it is imperative to keep a high index of suspicion for testicular plasmacytoma in the right clinical context when evaluating a patient with known multiple myeloma.
