Summary Objective: Sperm cryopreservation before gonadotoxic treatment is the basic and mos teffective method of preserving reproduction, which can be used during adolescence. The communication summarizes 26 years of experience in the operation of an oncological sperm bank, analyzes spermiograms of oncological patients, assesses the relationship between sperm pathology and diagnosis, and determines the number of deaths and the use of frozen sperm. Methods: During the existence of CAR 01 (assisted reproduction center), more than 50,000 spermiograms were performed. From January 1995 to December 2020, a total of 24,729 men were examined within the sperm bank, of which 1,448 (5.9%) had an oncological diagnosis. The spermiograms were evaluated according to current WHO (World Health Organization) manuals. Cryopreservation of sperm has undergone a major development. The rules for the storage of frozen cells have been laid down by Act No. 296/2008 Coll. since 2008. In 2019, the methodology „Cryopreservation of reproductive cells and tissues in patients before cancer treatment“ was updated. In all cases, the standard thawing technique was used. The sperms were processed by the swim-up method. As part of the treatment with assisted reproduction methods, oocytes were fertilized by the ICSI (intracytoplasmatic sperm injection) micromanipulation technique. Results: Out of 1,448 examined spermiograms in men with oncological diagnoses, testicular cancer was present in 43.7% of patients and malignant diseases of lymphatic and hematopoietic tissue were found in 24.1%, of which 70,1% included Hodgkin‘s lymphomas and 29,9% were non-Hodgkin‘s lymphomas. Leukemia was found in 7.9%, bone and cartilage cancers in 6.8%. The age of the clients of the whole group ranged from 13 to 64 years (27.2 ± 6.8 years). A total of 38.3% of men had normozoospermia, 54.2% of spermiograms showed pathological findings in 1 to 3 evaluated parameters and 7.5% of patients had azoospermia. Severe asthenozoospermia (mobility ≤ 10%) was detected in 57.2% of men and severe oligozoospermia (concentration ≤ 1 × 106 mm3) in 22.3% of patients. The lowest values of the spermiogram were found in men with testicular cancer; the best values were seen in CNS (central nervous system) cancers. The cryopreservation of sperm was performed in 1,340 cases (92.5%). So far, a total of 160 men (11.9%) have used frozen sperm, of which 6.2% in our center. In these 83 cases, the ICSI technique was always used, 38 clinical pregnancies (45.8%) and 32 births were achieved. We have registered 424 completed storages of semen (31.6%), of which 148 (11.0% of all oncology patients) were made due to death and the others at patients’ request. Using the sperm of the dead is a specific issue. Conclusion: In cancer patients, sperm pathologies occur in high percentage. The lowest spermiogram values were found in men with testicular cancer. It is necessary to take into account long-term storage and fertilization by micromanipulation methods. The number of men who die is significantly higher than the number of those who use sperm to treat infertility. Cryopreservation of sperm should be offered to each patient prior to the therapy leading to the destruction of spermatogenesis.

Abstract I wrote this journal in March 2020 prior to the World Health Organization declaring the COVID-19 infection as a worldwide pandemic on March 11. The situation in Singapore was unfolding even as public healthcare institutions were tasked to lead the charge to contain the novel coronavirus as it was then called. This journal describes my experiences and impressions during my work in an isolation ward at the National University Hospital during this early period. I was to be catapulted into Pandemic Team 3 in the second and third weeks of February 2020. The urgency of hospital measures to respond to the novel coronavirus meant that the general medicine consultant roster which I was on was hijacked to support the pandemic wards. I thought wryly to myself that it was a stroke of genius to commandeer the ready-made roster of senior physicians; it would have been difficult for the roster monster to solicit senior physicians to volunteer when there were still so many unknowns about this virus. Graphic images of the dire situation in Wuhan, China, were circulating widely on social media. It was heart-wrenching to read of Dr. Li Wen Liang’s death. He had highlighted the mysterious pneumonia-causing virus. The video clip of him singing at a karaoke session that went viral underscored the tragedy of a young life cut short. Questions raced in my mind. “Are we helpless to prevent the spread of this virus?” “Is the situation in China to be replicated here in Singapore?” This seemed incredulous, yet, might it be possible? The immediate responses that jumped up within me was “yes, it’s possible, but let’s pray not. Whatever has to be done, must be done.”

Background. The attribution of non-ClinicalTrials.gov registries among registered trials of the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) had increased until 2013. However, the attribution after 2013 is unknown. Moreover, no study has investigated the usage of non-ClinicalTrials.gov registries after 2015 or compared the characteristics of trials under non-ClinicalTrials.gov and ClinicalTrials.gov registries. Methods. This will be a meta-epidemiological study. It will include all trials registered on the ICTRP from January 1, 2014, to December 31, 2018. First, we will describe the total attribution of non-ClinicalTrials.gov registries among the ICTRP-registered trials for each year and each registry worldwide. Second, we will compare the recruitment status, target sample size, study type, study design, countries, prospective registration, funding, and study phase of the trials on ClinicalTrials.gov and other registries from 2014 to 2018. Third, we will report on the distribution of primary registries of trials from the top five countries in order of the quantity of registered trials on the ICTRP. Ethics & Dissemination. Ethics approval is not required for this study. This protocol has been registered in the University Hospital Medical Information Network Clinical Trials Registry (UMIN-CTR). The findings will be published in a peer-reviewed journal and may be presented at conferences. Trial Registration Number. UMIN000034401

Objective: To evaluate the present use of diuretics in our institution, and determine the appropriateness of that use and the incidence of adverse reactions and interactions. Design: This retrospective study describes the indications for use of an identified drug or combination of drugs. By the time the data were collected, some patients had been discharged or had died. Setting: The study was carried out in a referral center, the University Hospital “Virgen Macarena,” Seville, Spain. Patients: All patients receiving diuretic therapy. Those undergoing hemodialysis or receiving home care were excluded from the study. Intervention: A therapeutic audit was performed using specific standards of reference. Two models were used — one for each of the most frequent indications, ascites and congestive heart failure (CHF). Main Outcome Measures: A structured protocol gathered data on (1) demographic characteristics, (2) causes of admission and pathologic antecedents, (3) diuretic treatment, (4) basic controls (24-h diuresis and daily basal weight), (5) clinical evolution, and (6) concurrent complementary studies. The protocol included a checklist of the most frequent adverse drug reactions and interactions whose degree of causality was determined by applying the modified algorithm of Karch-Lasagna, used in the World Health Organization voluntary reporting system of adverse drug reactions. Results: One hundred twenty-six patients (16% of total admissions) received diuretic therapy. Of these, 71% were analyzed; information in the medical records was incomplete for the rest (29%). Fifty-one percent of the patients were more than 60 years old. The most frequent admission diagnoses were cardiovascular (51.5%), followed by digestive (16.7%) diseases. A total of 134 cardiac symptoms was seen in 50 patients. The most notable were acute pulmonary edema (26%), ischemic cardiopathy (12%), and cardiogenic shock (8%). Most patients receiving diuretic therapy (47.3%) were admitted to the internal medicine service. The most-prescribed diuretic was furosemide (59%), followed by spironolactone (27%). The combined use of furosemide and spironolactone occurred in all but 1 of the patients with hepatic ascites (92%), whereas in those with CHF the figure for the combined use of furosemide and spironolactone fell to 38% (p = 0.001). In 63% of the patients with ascites, the spironolactone dosage was changed in the first 48 hours of treatment. There was a high percentage of deaths (21%) in the study patients. Conclusions: Therapeutic strategy often does not follow the guidelines laid down in the standards of reference on diuretic use in serious CHF and/or ascites in this institution.

PURPOSE: A multicenter phase II trial was conducted to evaluate the efficacy and toxicity of gemcitabine in patients with relapsed or refractory aggressive non-Hodgkin's lymphomas (NHL). PATIENTS AND METHODS: Thirty-one patients with B-cell intermediate or high-grade NHL (Working Formulation) were enrolled onto the study. The median age was 61 years, with a Karnofsky performance status of ≤ 80% in 65% of patients. Forty-eight percent had stage III or IV (Ann Arbor Classification) at study entry. Pretreatment consisted of one, two, or three chemotherapeutic regimens in nine, 11, and 11 patients, respectively. Gemcitabine 1,250 mg/m2 was administered intravenously over 30 minutes on days 1, 8, and 15 of a 28-day schedule. RESULTS: Thirty patients were assessable for efficacy, and 31 were assessable for toxicity. No complete responses were observed, but six patients showed a partial response, 11 stable disease, and 13 progressive disease. The overall response rate was 20% (95% confidence interval, 8% to 39%) for assessable patients and 19% (95% confidence interval, 8% to 34%) for the intent-to-treat analysis. The median duration of partial response was 6 months (range, 3.7 to 15+ months). Nonhematologic World Health Organization grade 3 toxicity included hepatic toxicity in four patients and infection in two. Hematologic toxicity was observed as grade 3 anemia in three patients, grade 3 leukopenia in two patients, grade 3/4 neutropenia in two patients, and grade 3/4 thrombocytopenia in six patients. CONCLUSION: The present schedule of gemcitabine displays modest efficacy and mild toxicity in pretreated aggressive NHL.

Hodgkin's Lymphomas

Background: Lymphomas have been a global challenge for many decades and despite measures for prevention and management, the incidence continues to increase. There are two main categories, which are Non-Hodgkin’s Lymphomas and Hodgkin’s Lymphomas and most common etiologies are environmental, genetic alteration, radiation and some viruses. Objective: To describe pathology characteristics of lymphomas in Rwanda based on Hematoxylin and Eosin stained glass slides and immuno histo chemistry, and classify them according to clinical aggressiveness. Patients and Methods: We conducted a retrospective observational and descriptive study from January 2013 to December 2019. Lymphoma cases were retrieved together with relevant clinical and pathological information, and reviewed by independent pathologists. Histological diagnosis was classified according to the 2008 World Health Organization system in order to assign clinical aggressiveness of the lymphoma. Results: Three hundred and six lymphoma cases were enrolled. Males contributed to 57% of all reviewed case, and slightly over 50% were young aged ≤35 years. Approximately 191 (62%) of cases were nodal lymphomas. Approximately one fifth (18%) of lymphoma cases were HIV positive. Most 213(70%) cases were Non-Hodgkin’s Lymphomas of aggressive forms 164(77%). Among 164 cases of aggressive Non-Hodgkin’s Lymphomas, diffuse large B cell lymphoma was the leading subtype 91(55.5%), followed by solid lymphoblastic lymphoma 32(19.5%) and Burkitt lymphoma 17(10.4%). Among all Hodgkin lymphoma cases, 90(97%) were classical Hodgkin lymphomaof nodular sclerosis subtype. Hodgkin lymphoma patients were younger compared to Non-Hodgkin’s Lymphomas patients (mean age of 24.78±16.3 years versus 38.6±22. 5years, p=.000). Conclusion: Substantial proportion of Lymphomapatients in Rwanda were also HIV positive. Interestingly, Non-Hodgkin’s Lymphomas in Rwanda are predominated by the most aggressive forms, and these mostly affect a younger population. Optimal characterisation of such cases, using advanced methods, is recommended.

Background/Aims: Although the number of domestic adverse drug reactions (ADRs) reported in Korea is rapidly increasing, the analysis of ADRs in cancer patients remains limited. We sought to investigate the clinical features of ADRs in cancer patients.Methods: ADR data were collected from a spontaneous reporting system at single university hospital, between July 2010 and June 2015. ADR cases assessed to be “unlikely” or “unclassifiable” as per the criteria of the World Health Organization-Uppsala Monitoring Center were excluded. Additional medical information was retrospectively collected from chart reviews, and clinical features of ADRs were analyzed.Results: In total, 1,455 cases were reported. Of these, 822 ADRs (52.1%) were observed in cancer patients. The mean age of cancer patients was 60.8 years (range, 17–90 years), and 45.9% were male. The most prevalent clinical features were gastrointestinal abnormalities (32.6%), such as nausea and vomiting, followed by skin (28.5%) and neurologic manifestations (26.0%). Fifty-one (6.2%) and 296 cases (36.0%) were classified as severe and moderate, respectively. The most common causative agents were parenteral nutrition (PN) supplements (40.4%), followed by antibiotics (17.8%), analgesics (16.7%), iodinated contrast media (ICM, 10.6%), and vitamins (3.9%). Antineoplastic agents were responsible for 2.9% of cases. PN supplements were commonly associated with severe reactions.Conclusion: Although it is well known that antibiotics, ICM, and analgesics induce ADRs, PN supplements, vitamins, and antineoplastic agents should also be considered as common causes of ADRs in cancer patients. Further investigation and monitoring to determine the causality associated with these agents is required.

Abstract This chapter describes the various ways in which the non-Hodgkin’s lymphomas can involve the skin, how these diseases should be assessed, standard treatments available in 2002, and new directions in research. The goal of the session is to succinctly review recent developments in lymphoma classification and treatment as they apply to the unique aspects of lymphoma when manifest in the skin. In Section I, Dr. Eric Hsi reviews the special characteristics of the lymphomas seen when they proliferate in the skin and the application of the new World Health Organization classification system to the cutaneous lymphomas, emphasizing the unique challenges of recognizing and correctly classifying these diseases. He summarizes the evidence in favor of including the skin lymphomas in the overall lymphoma classification scheme and concludes with a practical description of the specific skin lymphoma entities. In Section II, Dr. Joseph Connors describes the current optimal treatment of the B-cell lymphomas when they present in or metastasize to the skin. Building on the classification scheme described by Dr. Hsi, Dr. Connors outlines a treatment approach based on current understanding of pathophysiology of these diseases and application of each of the effective modalities available for cutaneous lymphoma including radiation, chemotherapy, and immunotherapy. In Section III, Dr. Francine Foss concludes the session with a discussion of the different T-cell lymphomas that start in or spread to the skin concentrating on mycosis fungoides, cutaneous anaplastic large cell lymphoma and peripheral T-cell lymphoma. She includes comments on the newer anti-T-cell chemo- and immuno-therapeutics focusing on agents and techniques specific for cutaneous T-cell lymphomas.

The prevalence of circadian rhythm sleep-wake disorder (CRSWD) among patients with schizophrenia is not clear. The effect of comorbid CRSWD on such patients has also not been fully evaluated yet. Outpatients with schizophrenia in the maintenance phase who visited Tokyo Women’s Medical University Hospital between April 2018 and March 2019 participated in this study. The Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impressions–Severity Illness Scale (CGI-S), Global Assessment of Functioning (GAF), World Health Organization Disability Assessment Schedule II, Insomnia Severity Index (ISI), and Morningness–Eveningness Questionnaire (MEQ) were administered, and the patient responses with and without CRSWD were compared. Of the 105 patients with schizophrenia, 19 (18.1%) had CRSWD. There were trends toward higher BPRS and lower GAF scores in the CRSWD group than in the non-CRSWD group, although these did not reach statistical significance following a false discovery rate correction. Among the BPRS subitems, the anxiety scores were significantly higher in the CRSWD group than in the non-CRSWD group (p < 0.01). CRSWD was highly prevalent among patients with schizophrenia in the maintenance phase. Comorbidities of CRSWD may affect psychopathological characteristics and psychosocial functioning.
