Background Adherence to HIV care is complex, as barriers to care are multidimensional, particularly for ethnic minority women. Mobile health (mHealth) solutions are supportive in improving HIV health care outcomes. In the United States, however, mHealth interventions are not widely implemented in public HIV clinics and have not been customized for women. There is an unmet need for culturally and linguistically appropriate mHealth interventions that address the health care needs of minority women living with HIV. Objective This study aims to describe a protocol investigating the feasibility of an mHealth intervention for treatment adherence among women living with HIV. This is a two-phase, mixed methods, pilot randomized controlled trial that begins with qualitative patient interviews to inform the system design. Participants will be block randomized by language (English, Spanish, and Haitian Creole) to 1 of 2 study arms. Methods Women (age ≥18 years) who were followed up at the women's HIV clinic of an academ minority women living with HIV. Trial registration ClinicalTrials.gov NCT03738410; https//clinicaltrials.gov/ct2/show/NCT03738410. International registered report identifier (irrid) DERR1-10.2196/17656.Introduction Leiomyosarcomas are rare and heterogeneous group of tumors that account for less than 1% of adult malignancies. More than 50% of all vascular leiomyosarcomas occur in the lower part of vena cava. Since the first description of Perl and Virchow in 1871, only approximately 450 cases have been reported in literature. Presentation of case The patient presented due to abdominal pain and weight loss. Based on the imaging evaluations a retroduodenal tumor with compression of the inferior vena cava was observed. In the explorative laparotomy a leiomyosarcoma originating from the inferior vena cava was identified. Considering the extensive intramural and intraluminal tumor manifestation, the patient underwent a segmental resection of the vena cava. Reconstruction was achieved by implanting a polytetrafluoroethylene (PTFE) prosthesis. Postoperatively a stenosis developed due to a pericaval haematoma with consecutive compression of the prosthesis. An angiographic implantation of a stent was successfully performed. In the 24-month follow-up, the patient is free of symptoms and tumors. Discussion Leiomyosarcomas of the vena cava are classified anatomically according to their relationship to the liver and renal vessels. The clinical symptoms depend on the affected segment. The therapy of choice is radical en bloc tumor resection. After resection, the options for reconstruction include placement of a synthetic graft, primary repair and patch repair. Conclusion Due to a variety of topographic and tumor biological sarcoma manifestations, no standard has been established for the resection of this entity. The extent of resection should be planned individually.Introduction Malrotation of gut is a congenital anomaly of foetal intestinal rotation and it is mostly discovered in early childhood as acute intestinal obstruction. This condition is very rare and often silent in adults. Presentation of case We present a case of 44-year-old woman admitted with acute abdominal pain. The abdominal CT scan showed ileal conglomerate loops with thickened walls filled of liquid in the right iliac side. Laparotomic Ladd's procedure was performed successfully with division of Ladd's band, adhesiolysis, reconstruction of Treitz's ligament, small bowel resection and Merckel's diverticulum removal. The patient made an unremarkable recovery. Discussion We discuss the rarity of intestinal malrotation in adulthood and made a literature review comparison of the therapeutic options available. Conclusion Intestinal malrotation is a rare entity and adult presentation is even rarer. Some cases are asymptomatic, but when symptomatic a volvulus should be promptly suspected to avoid complications such as bowel ischemia.Introduction With the rarity and benign nature, angioleiomyoma is a tumor of disputed etiology that originates from the tunica media of the blood vessels. Lacking any characteristic clinical or radiological features, often leading to preoperative misdiagnosis, it is only diagnosed confidently on the basis of histopathology; for this reason combined with the rarity, angioleiomyoma would not be usually found at the top of the differential diagnosis list. Local excision is usually curative with excellent prognosis. Case This report discusses a case of a 60-year-old healthy lady who complained of a chronic painless mass in the right 2nd digit. Originating from the proper ulnar digital artery, it was excised with no complications. Histopathology results confirmed the diagnosis of angioleiomyoma. No recurrence was observed 6 months following the procedure. Discussion Out of the handful published papers concerned with angioleiomyoma in hands, few report the origin to be the digital artery. CPI0610 Conclusion Further awareness about this tumor is required and it should be included in the differential diagnoses list of the treating surgeon.Introduction Leiomyosarcomas (LMs) of the inferior vena cava (IVC) are very rare neoplasms seldom reported in the literature. The majority of patients does not present with specific abdominal pain and IVC LMs are used to become symptomatic with the increase of tumor volume. The role of chemotherapy or radiotherapy is not yet defined and surgical resection seems to be the only chance to improve survival rates. Presentation of case We present a case of a 58-year-old female with a recent diagnosis of IVC LM who underwent surgery with a partial resection of the anterior wall of the vein using a lateral and partial vein clamping. The primary repair of the defect could result in stricture of the vein, so a parietal peritoneum patch was used for the vein reconstruction. The postoperative course was uneventful. Discussion Actual evidence suggests that vascular sarcomas have limited responsiveness to cytotoxic chemotherapy and chemoradiotherapy, so surgery is the treatment of choice. Major surgery entailing multivisceral and complex vascular resection is usually necessary to achieve negative margins and accurate vascular reconstruction techniques are mandatory to avoid serious circulatory complications. Different kinds of graft (biological or synthetics) are available for the reconstruction, with intrinsic advantages and limitations. The use of peritoneal patches seems a valid and cheap option for vascular reconstruction and it is gaining great attention in recent years. Conclusion This case demonstrates that peritoneal graft could be a safe option to manage IVC defects in expert hands. A brief review of literature is also included.
