Primary cutaneous lymphomas (PCLs) are the second most common group of extranodal non-Hodgkin lymphomas (NHL) with an estimated annual incidence of 1/100.000. Interferons (IFNs) are used in mono or combination therapy for cutaneous lymphomas especially for cutaneous T-cell lymphomas (CTCL) for years. IFN-α is the most widely-used type for cutaneous lymphomas. IFN-α has been shown to be a highly active agent in CTCL with response rates ranging from 40% to 80%. In this review, the current information about PCLs and IFNs treatment is summarized.

Seabirds are species in a collection of avian orders that live on and feed in saltwater and include penguins; albatrosses and petrels; gannets and cormorants; and gulls, terns, and auks. They are at risk from human activities with habitat loss, fisheries bycatch, food shortages, introduced predators and pollution impact. These effects are all exacerbated by human-induced climate change. Many researchers, non-governmental organizations, communities, and governments are working to conserve endangered seabird species by developing and implementing technologies and conservation management systems to assist seabird conservation. More recently moves are afoot to ensure organizations share data and outcomes.

Mesenchymal stem cell (MSC) transplantation may be an alternative to liver transplantation for patients with end-stage liver disease. A 24-year-old patient with Hepatic Encephalopathy due to alcoholic liver cirrhosis underwent UCMSC transplantation because there were no donors available for liver transplants involving adult deceased and living individuals. The patient was given allogeneic Umbilical cord-derived MSCs, which were then cultured following accepted practices. Subsequently, the UCMSCs were infused through the intravenous route 3 times at the interval of 30 days. Serum bilirubin, globulin, and ammonia levels were improved after the infusion and the morphology of the liver and spleen had also improved.

Successful implant restoration is depending on an adequate surgical and prosthetic protocol. In the last few years an increase in Peri-Implantitis has been attributed, in part, to the excess cement left around the implant collar and threads, leading in many cases to bone loss and even the complete failure of the implant treatment [1-5]. This article will attempt: 1. To describe a proper cementation protocol for cement-retained implant restorations to reduce cement induced implant failures, and 2. To review the alternative implant restorative options to cement-retained crowns such as screw-retained restorations, screwless and cementless implant restorations, screw-retained-cemented implant crown, angulated screw channel restorations, the lingual locking screw-retained restorations and the multi-unit abutment restorations.

Introduction: Acute kidney injury (AKI) is one of the complications associated with severe COVID-19 infection, and it can present in up to 20% to 40% of the cases; of these, approximately 20% will require renal replacement therapy (RRT). Objective: To establish clinical and laboratory characteristics in a group of patients from Colombia with COVID-19 infection and AKI that received intermittent and prolonged RRT with the GENIUS® 90 technology in between March and July 2020. Design: Cross-sectional study. Results: 78.9% of participants were men and 21.1% were women. The main comorbidities were the following: Hypertension (65.3%), diabetes mellitus (38.9%), obesity (26.3%), cancer (5.3%), Chronic obstructive pulmonary disease (11.6%), cardiovascular disease (23.2%), active smoking (11.6%). 33.7% had chronic kidney disease (CKD) in the average serum creatinine on admission was 4.4 mg/dl. The following inflammatory markers were elevated: C-reactive protein (CRP), d-dimer and ferritin (20.3 mg/dl, 931mcg/l and 1174 ng/ml, respectively). 63.5% of patients underwent sustained low-efficiency dialysis (SLED) (6 to 12 hours) and the rest of the patients (36.35%) underwent conventional hemodialysis (less than 4 hours). The mortality of the total patient sample was 36.9%, lower in patients with CKD than in patients with no previous renal disease history (18.7% and 40.1%, respectively). Conclusion: Renal complications are frequent in patients with severe COVID-19. The development of AKI could be an isolated prognostic marker associated with an increase in mortality in patients with COVID-19, and one of the options is intermittent and prolonged RRT with the GENIUS® 90 system.

Background: Down syndrome (DS) is associated with various congenital diseases and malformations, including those of the kidneys and urinary tract. It has been thought that renal tubular acidosis (RTA) is more frequent in this population. The objective of this study was to assess the frequency of RTA and, secondarily, of other renal and urological disorders in persons with DS. Method: An observational, ambispective, descriptive and cross-sectional study of patients diagnosed with RTA, or suspected kidney or urological disorders, was carried out from July 2016 to September 2017 at the Down syndrome clinic of the Mexican National Institute of Paediatrics. Urinalysis was performed, along with analyses of venous blood gas, sodium, potassium, chlorine, calcium, phosphorus, albumin and creatinine. Those with any abnormal values were referred to nephrology for diagnostic evaluation. Results: Of a total of 700 patients seen at the clinic, 47 met the selection criteria. Of these, 32 had no RTA or other renal or urological alterations. The remaining 15 continued to the second phase of the study, where 6 were diagnosed with nephropathy or uropathy (RTA, systemic arterial hypertension, monosymptomatic familial haematuria, mild renal failure secondary to reflux nephropathy, urinary tract infection or right ureteropelvic stenosis). Four had mild metabolic acidosis without meeting the criteria for diagnosis of RTA. Conclusion: RTA is not more common in children with Down syndrome. Nephropathies and uropathies should be investigated in the evaluation of DS patients.

A critical component of the radiation regimen for treating cancer patients is the precise dose delivery to the treatment organ while minimizing the dose to the healthy tissue. This study aims to evaluate in-field organ dose and dose distribution outside the target organs to estimate the excess lifetime risk of second cancer. The study was carried out with a male Alderson Rando Phantom. 20 sets of thermoluminescence dosimeters (MTS-100) were used in this study. The in-field organs absorbed dose was measured by inserting TLDs at different geometrical depths of the left lung, right lung, and stomach, and for peripheral organs skin dose TLDs were placed at the surface of the corresponding organs. Target organs were irradiated at 100 cGy and 200 cGy by a 60Co teletherapy unit, and irradiated TLDs were read out by a RE-2000 TLD reader. For precise dose delivery to the cancerous organs by 60Co teletherapy, the depth dose correction factor for lung cancer treatment is 0.8667 ± 0.01, and for the stomach is 0.7856 ± 0.017. In the case of the treatment for the lung and stomach, the closest organs received significant doses compared to the other distant organs. Thus, the risk of second cancer due to the peripheral dose is obtained. The stomach is at the highest risk when the lung is the target and the liver is at the highest risk when the stomach is the targeted organ.

Anal melanoma is a rare and highly aggressive mucosal melanocytic malignancy. It is the third most common after melanomas of the skin and retina. The peak incidence in seen in the sixth and seventh decades. The clinical symptoms are pain, anal mass, bleeding per rectum, tenesmus or change in the bowel habits. It affects anal canal, rectum or both with a tendency to spread along submucosal planes. It is mostly beyond complete resection at the time of diagnosis and majority of patients die of metastasis. MR imaging significantly increases the diagnosis of anal melanoma in its early stages.

Background: Patients with chronic kidney disease (CKD) are at the risk of increase hospital admission as compared to the general population, due to various reasons. They have increased vulnerability to cardiovascular diseases (CVD) as well as infections, therefore they usually got admit in health care units due to various reasons. The causes of hospitalization in CKD patients in this part of the world are not studied well. Methods: This cross sectional study was conducted in The Kidney Centre Post Graduate Training Institute (TKC-PGTI) of Karachi. Variables included in the study were age, gender, are of residence, ethnicity, smoking status and level of education. Comorbid conditions like causes of CKD and causes of hospitalization. Data analysis performed by using software IBM SPSS 21. Results: Total of 269 patients were enrolled in our study. The male 148(55%), mean age was 55 years. The most common cause of hospitalization in our population was infection148 (55%) and urinary tract infection (UTI) was the most common site of infection 55 (20%) followed by sepsis of unknown origin 29(10.8%). Cardiovascular events like volume overload 32 (11.4%) and acute coronary syndrome 20(7.4%) were the second most important cause of hospitalization. Conclusion: Hospitalization of CKD patients is high, and in our population infection is found to be the leading cause of hospital admission. Infection originating from urinary tract is more common in all stages of CKD patients, while blood born infection originating from double lumen (DL) dialysis catheter or arteriovenous fistula (AVF) cannulation is more common in dialysis population. Cardiovascular events, both acute coronary syndrome and pulmonary edema due to volume overload followed the infections.

Background: Early and effective identification of childhood neurodevelopmental disorders remains a critical task of all pediatric healthcare professionals, which is critical to the well-being of children and their families. Methods: A retrospective review of medical records of all preschool children referred to a Child Development Centre (CDC) in North-West England, over a six-month period between Sept 2014 and Feb 2015 was conducted. The local multi-professional approach to the clinical assessment and management of preschool children was described and the published literature on this topic was reviewed. Results: Twenty four different categories of professionals spanning the whole range of primary, secondary, and tertiary healthcare, social care and educational services were involved in the management of the patients. The largest group of professionals was the primary healthcare specialists. The ten different primary care professionals managed an average of 42% of the patients. The secondary healthcare providers were involved in the care of an average of 17%, tertiary care providers 10%, educational specialists 25% and social care professionals were involved with 5% of all the patients. The commonest diagnostic disorders were Speech/Language delay (56%), Global developmental delay (33%), Behavior difficulties (26%), Social communication concerns (21%) and Autistic spectrum disorder (19%). Conclusion: The high number and specialties of various healthcare professionals at all levels of care indicates the high social and economic investment required in managing the affected preschool children in the region. Childhood neurodevelopmental disorders in the preschool age represents a high level of public health significance.
