Obesity is a complex chronic disease and common comorbidity in kidney failure and is the leading causes of death and disability in this population. Guidelines do not specifically address the preferred weight management option(s) for obesity while on dialysis. Large body size is a limiting factor for consideration of a kidney transplantation. We report on a successful bariatric surgery with a young adult after 5.5 years on dialysis with hope for a future transplant. Success was demonstrated with progressive weight loss without adverse changes in renal clinical markers accompanied by improvements in exercise tolerance and health status thereby improving her suitability for a kidney transplant. Further studies and guidelines are needed to address weight loss options for those with obesity on dialysis and want to lose weight.

BACKGROUND: Isolated dislocations of the scaphoid are extremely rare types of injuries, commonly associated with severe ligament disruptions, and are occasionally misdiagnosed. Treatment options for dislocations of the scaphoid mainly include closed reduction, with or without internal fixation, and open reduction with ligament repair.
METHODS: A 59-year-old male worker sustained a twisting trauma of his right wrist, caused by a moving belt while he was operating a machine. When he presented at our emergency department, the patient complained of swelling, tenderness, and restriction of movement of the right wrist. Radiographs confirmed a primary complex partial radial dislocation of the scaphoid and some chip fractures of the capitate and hamate. Closed reduction with K-wire internal fixation was performed with the assistance of arthroscopy, and an excellent prognosis was achieved.
CONCLUSIONS: Arthroscopy-assisted reduction is a minimally invasive method to reduce the dislocated scaphoid and maintain the blood supply.

UNASSIGNED: Extra mammary Paget\'s disease (EMPD) is a rare disease characterised by intraepithelial involvement of the skin by non-squamous carcinoma cells in the vulva, perineum, and scrotum. Secondary EMPD is even rarer and accounts for roughly 25% of cases (Delport, 2012) [1]. Surgery (Mohs/wide local excision) is the standard treatment for primary non-invasive disease, but management of secondary invasive EMPD is less defined as there are no current treatment guidelines.
METHODS: A 76-year-old lady had a 1-year history of a pruritic perianal rash that was refractory to multiple topical agents. A biopsy confirmed a diagnosis of EMPD in June 2020 and on staging imaging was found to have metastatic disease in her right inguinal lymph node. Upon discussion at a multi-disciplinary team (MDT) meeting, she proceeded chemo radiation therapy followed by systemic chemotherapy as she had such extensive perianal disease that would make surgery quite morbid. She had interval imaging 3 monthly to assess response to treatment. In June 2021, the patient had a complete clinical response and has ongoing 6 monthly surveillance.
UNASSIGNED: EMPD is extremely rare and currently treatment options for secondary EMPD are still being navigated. Specifically, there are no current randomised control trials (RCTs) that compare outcomes in secondary EMPD between radiation therapy and surgery and in the context of stage III disease. This case report documents the treatment approach governed by MDT consensus and has a 1 year follow up. The case report has been reported in line with the SCARE 2020 criteria (Agha et al., 2020) [2].
CONCLUSIONS: The patient has had a good outcome with treatment, however ongoing surveillance is required.

Pulmonary large cell neuroendocrine carcinoma (LCNEC) is a rare but destructive tumor type, accounting for approximately 1% of all lung cancers, associated with poor prognosis. LCNEC is challenging diagnosing using biopsy specimens. While current LCNEC therapies include surgery, radiotherapy, and chemotherapy, it has not yet proved its greatest treatment strategies. Immunotherapy is rapidly emerging as a possibility for lung cancer treatment. However, there are scant reports in the literature regarding LCNEC immunotherapy. Therefore, the author here reports a case of LCNEC by immunotherapy, and retrospective reviews the present research status and progress of LENCE and corresponding clinical treatment progress. This case will supply valuable information for the treatment options for LCNEC. A 64-year-old male smoker was treated for one month for blood in his sputum. Chest radiography and computed tomography revealed a 3-cm solitary tumor in the left upper lung. We treated the patient with thoracoscopic radical surgery for upper left lung cancer. Postoperative pathology shows pulmonary LCNEC. We performed postoperative chemotherapy with a double-drug regimen holding platinum. Then, bevacizumab, paclitaxel, and the PD-L1 checkpoint inhibitor nivolumab were applied, but the patient progressed rapidly. Immunotherapy is an ineffective treatment possibility for these patients, even if PD-L1 expression is positive. A possible contributing factor is the timing of immunotherapy too late.

BACKGROUND: Mirror aneurysms are a rare subtype of multiple aneurysms, located in identical or adjacent arterial segment bilaterally. We report a case series of 3 such patients amongst whom one of them had 3 sets of mirror aneurysms and the other patient had 2 sets of mirror aneurysm on the same arterial segment which has not been reported till date.
METHODS: A retrospective analysis of 3 patients with incidentally detected multiple mirror aneurysms, who were treated with microsurgical clipping and coiling, was conducted. A systematic search was performed using the PUBMED database and relevant articles were reviewed with particular attention to incidence, associated conditions, risk factors and management strategies. Written informed consent was obtained from all of the patients for publication of this case report and accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal on request. This research work has been reported in line with the PROCESS criteria (Agha et al., 2018).
RESULTS: All the 3 patients were females with incidentally detected multiple mirror aneurysms. All the 3 patients were known Hypertensives. All the aneurysms were successfully clipped by a multistage, bilateral craniotomy except the one in the cavernous ICA, for which an endovascular procedure is planned. All of them had an uneventful postoperative course with the CT angiogram showing obliteration of all the clipped aneurysms except the one in the cavernous ICA.
CONCLUSIONS: Multiple mirror aneurysms represent a rare occurrence of a diverse pathology. Both these described types of cases have not been reported so far in the literature. The treatment strategy for mirror aneurysms should be determined individually based on the location, size, and morphology of the aneurysms, as well as, on the clinical manifestations of each patient.

Currently, large quantities of municipal solid waste (MSW) in many cities of the developing countries are being dumped in informal or formal but unregulated dumpsites that threaten the ecological environment and general public health. The situation in Dar es Salaam, Tanzania is of particular concern and is further challenged by a rapidly growing population and urbanization without adequate waste management systems. Current MSW treatment options have been selected based on the judgment and the experience of individuals with authority while underestimating the role of scientifically derived techniques. This study analyzes the most efficient waste treatment options, particularly scenarios with the lowest economic and environmental costs (EcC and EnC, respectively). It uses 12 years (2006-2017) of MSW management data and compares potential waste treatment options for the identified waste streams. A total of 108 different scenarios were designed, and a multi-criteria analysis method was applied to enable the identification of 11 scenarios with acceptable EcCs and EnCs. These formed an initial decision matrix of aggregation dominance that was then categorized into four groups, each represented by the most ideal point. Finally, the dominant scenario that formed the core for all considered options was found. It costs around $274,100 USD while saving about 1585 metric tons (MT) of CO2 emissions daily. This suggests that after all the MSW generated in the city is collected and segregated, organic waste should be composted whilst plastic, paper, glass, and ferrous metal should be recycled. After treatment, other waste will go to some form of landfill. Sustainable management of MSW in this city and others with similar conditions should consider particular local conditions and could use the methods and the findings of this study as a starting point.

BACKGROUND: Cranial irradiation is one of the main treatment modalities for central nervous system tumors. It carries many complications, one being occlusive radiation vasculopathy of large vessels. It is an underrecognized etiology for stroke, especially in the younger population. The pathophysiological process is controversial, but there is much literature supporting the theory of its being a secondary form of moyamoya disease.
METHODS: A 31-year-old Caucasian man with a history of pineal blastoma at the age of 3 years, which was treated with resection, radiotherapy, and chemotherapy, presented to our institution with right M1 stroke. Further assessment by computed tomographic perfusion study with acetazolamide demonstrated steal phenomenon of the right middle cerebral artery territory (type III response) with a small internal region of matched cerebral blood volume defect (that is, infarct core). Coincidentally, he was found to have multiple brain masses consistent with meningiomas. Occlusive radiation vasculopathy was the most likely culprit of the patient\'s stroke. The patient was treated medically with \"baby\" acetylsalicylic acid and clopidogrel for 3 months, then continued only on baby acetylsalicylic acid.
CONCLUSIONS: Late-onset occlusive radiation vasculopathy is a potentially severe iatrogenic manifestation of radiotherapy that requires a high index of suspicion as an etiology of stroke in young population, especially those with coexistent meningioma that might be a strong indicator for occlusive radiation vasculopathy as the stroke culprit. We reviewed the available literature to better understand the pathogenesis, clinical presentation, and treatment options of occlusive radiation vasculopathy. Applying perfusion studies with acetazolamide measures the cerebrovascular reserve in patients with occlusive radiation vasculopathy, which could help in determining the appropriate available treatment option.

BACKGROUND: With the newly described one step melanoma surgical approach, some patient groups could be successfully treated within one surgical session. Depending on the tumour thickness (measured preoperatively) at a later stage (also depending on the ultrasound findings of the locoregional lymph nodes) the respective surgical intervention is planned with the respective field of surgical safety (one-stage melanoma surgery with or without removal of lymph nodes). The innovations could make to some extent some of the already existing algorithms more difficult (due to the introduction of a high-frequency ultrasound to determine the tumor thickness preoperatively as an absolute prerequisite for dermosurgical centres), but it would also lead with absolute certainty to better or least optimal results regarding the prognosis, the side effects and the financial factor also.
METHODS: We present a patient from the Department of Dermatology, Venereology and Dermatologic Surgery at the Medical Institute-Ministry of Interior (MVR-Sofia), treated with the one-step melanoma surgery method with perfect final results. The preoperative tumour thickness determined via ultrasound and the postoperatively measured histological tumour thickness was identical: between 0.98 and 1 mm, which allowed removal of the melanoma lesion with a field of surgical security of 1 cm in all directions and did not require additional removal of a draining lymph node or excisions.
CONCLUSIONS: Thanks to this new approach, some patients could avoid one surgical intervention, which could be interpreted as a significant advantage or probably also survival benefit. This methodology and its successful application were first officialised by the representatives of the Bulgarian Society for Dermatologic Surgery- (BULSDS), and the purpose of this action, in general, is to fully improve clinical management of patients suffering from cutaneous melanoma in terms of compactness by 1) reducing the number of unnecessary surgeries or the number of surgical interventions in general; 2) reducing side effects occurring in surgeries and 3) introducing a serious optimization in terms of financial resources needed or used in the second hospitalization of patients. The question remains open whether the accepted or the current recommendations for surgical treatment of melanoma will be transformed or adapted for the matching patient groups.

Diffuse malignant peritoneal mesothelioma (DMPM) is generally an understudied disease, largely because most molecular and clinical studies of mesothelioma have been conducted in patients with the more common malignant pleural mesothelioma. We present the case of a 45-year-old male that initially presented with abdominal discomfort and ascites. Diagnostic workup revealed advanced DMPM. Bimodal treatment was stared with cytoreductive surgery and hyperthermic intraperitoneal perfusion with chemotherapy procedure, followed by pemetrexed systemic monotherapy. After the disease progression, and because of a very good previous treatment response to pemetrexed, we decided to rechallenge systemic pemetrexed, along with the introduction of cisplatin. Although the intent behind systemic treatment was at first solely palliative, overall survival after the initial diagnosis was 50 months. Treatment based on rechallenging pemetrexed with or without cisplatin in patients with advanced DMPM can result in a quite satisfactory disease control and symptom management.

Neuroendocrine tumor (NET) is detected in the examination of polypectomy material, presenting as rectal polyp. Since this is a rare case, we aimed to summarize the approach to rectal NET\'s.
