Management of advanced pelvic cancer by exenteration.

AIM: To describe our results in managing locally advanced primary or recurrent pelvic malignancies. METHOD: Investigations included: clinical, laboratory, endoscopic (rectoscopy and colonoscopy) examinations, ultrasound scan, and CT scan or MRI of the abdomen and pelvis, to determine the extent of the pelvic malignancy. A careful explorative laparatomy of abdomen and pelvis was performed, followed by anterior, posterior or total pelvic exenteration. RESULTS: In the period June 1995-Jan 2002, 7 anterior, 2 posterior and 51 total pelvic exenterations were performed in 60 patients, distributed as follows: 28 for rectal cancer (12 primary, 16 recurrent), 20 for cervical cancer (9 primary, 11 recurrent) and 12 for other pelvic malignancies. The median survival time and overall 5-year survival rates were as follows: primary rectal cancer--50 months and 32%; recurrent rectal cancer--31 months and 17%; primary cervical cancer--46.4 months and 41% and recurrent cervical cancer--23.4 months and 16%. During the same period, 559 of our patients were treated for primary or recurrent rectal cancer by different types of straightforward resection. CONCLUSION: Pelvic exenteration is justifiable in cases of locally advanced primary and recurrent malignancies of rectum, cervical cancer and possibly in cases of other pelvic malignancies.     

Cytoreductive surgery for ovarian cancer.

AIM: The aim of this study is to describe the technique of managing peritoneal dissemination in patients with ovarian cancer, based on radical surgical excision and, later, perioperative chemotherapy. METHOD:Treatments included complete surgical resection of the peritoneal disease, and intraperitoneal intraoperative and postoperative chemotherapy, using Adriamycin intraoperatively, and Cis-platinol next 1-5 postoperative days. RESULTS: Eleven cytoreductive procedures were performed between 1996 and 2002. Eight patients with primary ovarian cancer underwent total hysterectomy with bilateral adnexectomy, omentectomy and peritonectomy of the pelvic cavity. In 3 cases with recurrent ovarian cancer, peritonectomy alone was performed. Bowel resection was performed in all patients. The median operation time was 279 min (range 190-500min). Median total blood loss was 919 mL (range 450-1330 mL). The median survival time was 22 months. CONCLUSION: Cytoreductive procedure offers satisfactory results in peritoneal carcinomatosis in patients with advanced primary ovarian cancer.     

PLGA-modified Syloid®-based microparticles for the ocular delivery of terconazole: in-vitro and in-vivo investigations

The eye is an invulnerable organ with intrinsic anatomical and physiological barriers, hindering the development of a pioneer ocular formulation. The aim of this work was to develop an efficient ocular delivery system that can augment the ocular bioavailability of the antifungal drug, terconazole. Mesoporous silica microparticles, Syloid^® 244 FP were utilized as the carrier system for terconazole. Preliminary studies were carried out using different drug:Syloid^® weight ratios. The optimum weight ratio was mixed with various concentrations (30 and 60%w/w) of poly (lactic-co-glycolic acid) (PLGA), ester or acid-capped and with different monomers-ratio (50:50 and 75:25) using the nano-spray dryer. Results revealed the superiority of drug:Syloid^® weight ratio of 1:2 in terms of yield percentage (Y%), SPAN and drug content percentage (DC%). Furthermore, incorporation of PLGA with lower glycolic acid monomer-ratio significantly increased Y%. In contrast, increasing the glycolic acid monomer-ratio resulted in higher DC% and release efficiency percentage (RE%). Additionally, doubling PLGA concentration significantly reduced Y%, DC%, drug loading percentage (DL%) and RE%. Applying desirability function in terms of increasing DC%, DL% besides RE% and decreasing SPAN, the selected formulation was chosen for DSC, XRD and SEM investigations. Results confirmed the successful loading of amorphized terconazole on PLGA-modified Syloid^® microparticles. Moreover, pharmacokinetic studies for the chosen formulation on male Albino rabbits’ eyes revealed a 2, 6.7 and 25.3-fold increase in mean residence time, C_max and AUC_0–24-values, respectively, compared to the drug suspension. PLGA-modified Syloid^® microparticles represent a potential option to augment the bioavailability of ocular drugs.     

Factors for Effective Identification of Patients at Nutritional Risk in Clinical Practice: Thematic Analysis of Qualitative Research

IntroductionDespite the high prevalence of malnutrition in patients at all levels of healthcare, early prevention and treatment of malnourished patients are often neglected and overlooked in clinical practice. The aim of this systematic literature review was to identify the factors considered most important by healthcare professionals in the identification and treatment of malnourished patients or those at risk of malnutrition.MethodsA systematic literature review of qualitative research was conducted. Documents published in scientific journals in English from 2011 to 2021 were searched in the PubMed (MEDLINE), CINAHL and ProQuest databases. The results were analysed with a thematic analysis of qualitative research findings.ResultsFrom the search set of 1010 results, 7 sources were included in the final analysis. Factors identified by health professionals as important in the identification and treatment of malnourished patients in clinical practice were grouped into five themes: unclear organizational structure; indefinite structure of nutritional care; poor continuity of nutritional care; lack of knowledge and skills of health professionals; lack of time and human resources.ConclusionsHealth policy must provide resources for nutritional care for patients at all levels of health care on the initiative of the highest professional bodies at the state level. To improve the nutritional care of patients in clinical practice, the management of health care institutions must promote and enable the professional and organizational establishment of clinical nutrition as a regular medical activity of the institution, develop clinical nutritional pathways, and promote evidence-based clinical practice and interprofessional collaboration.

Prevalence and Risk Factors of Urinary Incontinence Among Jordanian Women: Impact on Their Life

We estimate the prevalence and type of urinary incontinence (UI), possible associated risk factors, and the impact of UI on women's social and psychological well-being. The sample consisted of women attending a family medicine clinic at Jordan University Hospital (JUH) who answered a self-administered questionnaire. More than one-third of the sample reported the presence of UI. Stress type was the most frequently reported risk factor, followed by mixed incontinence, then urge. Age, diabetes, chronic cough, parity, and hysterectomy were positively associated with the presence of UI. Incontinence caused low self-esteem in more than half of the women who experienced it.     

Does Maternal HIV Disclosure Self-Efficacy Enhance Parent–Child Relationships and Child Adjustment?

Nondisclosure of maternal HIV status to young children can negatively impact child functioning; however, many mothers do not disclose due to lack of self-efficacy for the disclosure process. This study examines demographic variations in disclosure self-efficacy, regardless of intention to disclose, and assesses the relationship between self-efficacy and child adjustment via the parent–child relationship among a sample of HIV+ mothers and their healthy children (N = 181 pairs). Mothers completed demographic and self-efficacy measures; children completed measures assessing the parent–child relationship and child adjustment (i.e., worry, self-concept, depression). Across demographics, few mothers reported confidence in disclosure. Results from covariance structural modeling showed mothers endorsing higher self-efficacy had children who reported better relationship quality, and, in turn, reported fewer adjustment difficulties; higher levels of disclosure self-efficacy also directly predicted fewer adjustment problems. Findings offer support for interventions aimed at providing mothers with skills to enhance confidence for disclosing their HIV status.     

ALK-negative lung inflammatory myofibroblastic tumor in a young adult: A case report and literature review of molecular alterations

Rationale:Inflammatory myofibroblastic tumor (IMT) is a rare mesenchymal tumor that is prevalent among children and adolescents. Surgery is the most important therapeutic approach for IMT and complete resection is recommended. Although 50% of IMTs show anaplastic lymphoma kinase (ALK) rearrangements, crizotinib has proven an effective therapeutic approach. However, the genetic landscape of this tumor is still not fully understood and treatment options are limited, especially in the majority of ALK-negative tumors.Patient concerns:We describe the clinical case of a healthy 18-year-old female in whom a pulmonary nodule was incidentally detectedDiagnoses:Following a small increase in the size of the nodule, the patient underwent both ¹⁸FDG-PET/CT and ⁶⁸Ga-PET/CT, resulting in a suspicion of bronchial hamartoma.Interventions:The patient underwent surgery and a salivary gland-like lung tumor was diagnosed.Outcomes:After surgery, the patient was referred to our cancer center, where a review of the histology slides gave a final diagnosis of ALK-negative lung IMT. Given the histology, it was decided not to administer adjuvant therapy and the patient was placed in a 3-monthly follow-up program. The patient is still disease-free 2 years post-surgery.Lessons:Although there is no standard of care for the treatment of IMT, identifying genomic alterations could help to redefine the management of patients with negative-ALK disease. Our review of the literature on IMT and other kinase fusions revealed, in addition to ALK rearrangements, the potential association of ROS1, NTRK, RET, or PDGFR beta alterations with the tumor.
