The burden of headache disorders among adults in Peru: national estimates and a health-care needs assessment from a population-based door-to-door survey.

Background: We have previously found that almost two thirds (64.6%) of adults in Peru have an active headache disorder. Here, using data from the same sample, we present attributed burden at individual and population levels.

The prevalence and demographic associations of headache in the adult population of Peru: a national cross-sectional population-based study.

Background: The Global Campaign against Headache is conducting a series of population-based studies to fill the large geographical gaps in knowledge of headache prevalence and attributable burden. One major region not until now included is South America. Here we present a study from Peru, a country of 32.

Hope and Resilience Related to Fear of COVID-19 in Young People.

In the face of the psychological crisis of fear caused by the COVID-19 pandemic, it is relevant to know the positive impact of hope and resilience during this context. The purpose of this study was to determine the correlation between hope and resilience with fear of COVID-19 in young people. The design was non-experimental, cross-sectional, and correlational.

Structured headache services as the solution to the ill-health burden of headache: 1. Rationale and description.

In countries where headache services exist at all, their focus is usually on specialist (tertiary) care. This is clinically and economically inappropriate: most headache disorders can effectively and more efficiently (and at lower cost) be treated in educationally supported primary care. At the same time, compartmentalizing divisions between primary, secondary and tertiary care in many health-care systems create multiple inefficiencies, confronting patients attempting to navigate these levels (the "patient journey") with perplexing obstacles.

Degelification of alpaca semen and the effect of dilution rates on artificial insemination outcome.

Degelification of highly viscous alpaca semen was attempted using two enzymes: trypsin and collagenase. Dilution effect on artificial insemination was determined in alpacas. Semen from 4 male alpacas was collected, degelified, diluted, and inseminated into 80 female alpacas.

Diffuse cavernous rectal hemangioma--sphincter-sparing approach to therapy. Report of a case.

Diffuse cavernous rectal hemangioma is described through a case history. Presentation, diagnostic work up, pathophysiology, and therapy for this condition are reviewed. Emphasis is placed on rectal sparing surgical techniques in the management of this disease process that affects young, otherwise healthy individuals.

Comparison of omental splenic autotransplant to partial splenectomy. Protective effect against septic death.

The possible benefit of either partial splenectomy or splenic autotransplantation as protection against post-splenectomy sepsis was investigated. Sprague-Dawley rats were challenged with intravenous Streptococcus pneumoniae and the incidence of bacteremia and mortality were recorded. Animals were divided into four groups based upon the amount of splenic tissue conserved: total splenectomy (0%), partial splenectomy (62%), splenic autotransplantation (27%), or sham celiotomy (100%).

Massive abdominal wall desmoid tumor. Treatment by resection and abdominal wall reconstruction.

The management of a massive abdominal wall desmoid tumor in a young woman with Gardner's syndrome is discussed. Treatment options included primary radiation, subtotal excision with radiation, primary chemotherapy, or radical resection with abdominal wall reconstruction. The advantages and disadvantages of the various treatment options are discussed, and the technique of resection and reconstruction is explained.

Update on biologic behavior and surgical implications of neurofibromatosis and neurofibrosarcoma.

Two instances of neurofibrosarcoma arising in young siblings with neurofibromatosis are reported to add to the body of information concerning this potentially lethal complication of von Recklinghausen's disease. The optimum treatment to achieve control of the local disease, especially for centrally located tumors, has yet to be discovered. Results of recent data suggest that radical surgical resection combined with preoperative irradiation and chemotherapy may enhance local control of peripherally located sarcomas.
