Objective: Identify the frequency of negative appendectomy (NA) and associated
factors associated in a private hospital in Lima.
Methods: Retrospective study of all appendectomies performed between 2012
and 2013 at a private hospital of Lima-Peru. We reviewed the medical records of patients who underwent appendectomy and had a medical report of emergency.
We excluded the ones without pathology reports. Adjusted ORs were calculated
with a logistic regression model to identify factors associated with AN.
Results: Three hundred seventy-six appendectomies were performed for
suspected appendicitis 55.9% in women). The average patient age was 33.4 ± 17.6
years. We identified 28 AN cases of 363 patients (7.7%). We found that pain in
right flank (aOR: 5.4; 95%CI: 1.4-20.8), negative Mc Burney (aOR: 3.6; 95%CI: 1.3-
10.5), pain in hypogastrium (aOR: 3.1; 95%CI: 1.1-8.4) and no leucocitosis (aOR:
2.9; 95%CI: 1.2-6.7) were associated factors to AN. Gynecologic conditions (53.6%)
and complicated diverticular disease (14.3%) are the most common diagnosis in
AN cases.
Conclusion: The obtained results indicate that the presence of pain in the right
flank, negative Mc Burney, pain in hypogastrium and no leukocytosis are factors
that can be taken into account to prevent negative appendectomy.

Cardiovascular disease in human immunodeficiency virus-infection as a cause of hospitalization: a case-series in a General Hospital in Peru
Background
Cardiovascular disease in the context of human immunodeficiency virus infection has become a major clinical concern in recent years. In the current report we assess hospitalizations due to cardiovascular disease in human immunodeficiency virus patients in a Social Security reference hospital in Peru.
Methods
A retrospective study was carried out between January 1996 and December 2012 in a General Hospital in Lima, Peru.
Results
We included 26 patients hospitalized due to cardiovascular disease. Mean age was 46.3 years (SD 12.5), predominantly male (57.7%). Ten patients (38.4%) were in Acquired Immunodeficiency Syndrome stages. Seventeen (65.4%) received high-active-antiretroviral therapy. Eleven (42.3%) had cardiac involvement and 15 (57.7%) had non-cardiac vascular involvement. The most frequent causes of cardiac involvement were pericardial effusion and myocardial infarction. On the other hand, deep vein thrombosis and stroke were the most frequent for non-cardiac vascular involvement.
Conclusions
Cardiovascular disease is an important cause of hospitalization in Peruvian human immunodeficiency virus patients, with differences between immunosuppression stages. Further studies analyzing associated factors are warranted.

A Shocking Cystory
A39-year-old woman from the south highland of Peru
presented with abdominal distention, 10-kg weight
gain, and intense stabbing pain in right upper quadrant of
the abdomen. On physical examination, she had abdominal
dullness and distention. She had a history of a liver cyst
diagnosed by ultrasound 14 years ago. Three years ago a
second ultrasound showed 3 cysts inside the first one. She
did not receive any treatment before this hospitalization.
The patient used to raise dogs and livestock (sheep and cattle)
in her rural house when she was a child. The current ultrasound
showed large cysts in liver and spleen that were
confirmed by an abdominal computed tomography (CT) scan that revealed that both cysts contained hundreds of
smaller cysts inside. Laboratory results showed a positive
enzyme-linked immunosorbent assay (immunoglobulin G)
for hydatid cyst. Laparotomy was performed, and the liver
cyst was removed as well as the entire spleen.

¿Schwannoma gástrico de crecimientorápido o tumor del estromagastrointestinal?: presentación de casoclínico y revisión de la literatura
Sr. Director:
Los schwannomas, también conocidos como neurinomas, neurilemomas o fibroblastomas perineurales, se originan a partir de las células de Schwann del tejido nervioso periférico1,2. Pertenecen a la familia de tumores mesenquimatosos, son solitarios, de crecimiento lento, típicamente encapsulados y habitualmente bien diferenciados2,3. Pueden originarse del plexo de Auerbach (en la capa muscular) o del plexo de Meissner (en la submucosa), siendo el último el de menor frecuencia2. Su tamano˜ es variable (0,5-11 cm de diámetro). La localización más frecuente corresponde a las regiones cefálica y cervical1---3; raramente se originan en el tracto gastrointestinal, pero de presentarse ahí, el segmento más afectado es el estómago2.

Primary non-polipoid intestinal folicular lymphoma: case report and review of the literature
The primary intestinal follicular lymphoma is a rare disease described in the last classification of lymphomas from WHO. It is a localized disease
with excellent prognosis. We describe in this article ,a 64 year-old Peruvian female with abdominal pain and delayed vomiting for the last two
years, has undergone a partial intestinal resection due to bowel obstruction. There was a well-circumscribed annular tumor. A diagnosis of
non-polypoid primary intestinal follicular lymphoma was made. We report the case and review the literature in this article.
