Early-rectal Cancer Treatment: A Decision-tree Making Based on Systematic Review and Meta-analysis

Local excision (LE) has arisen as an alternative to total mesorectal excision for the treatment of early rectal cancer. Despite a decreased morbidity, there are still concerns about LE outcomes.This systematic-review and meta-analysis design is based on the “PICO” process, aiming to answer to three questions related to LE as primary treatment for early-rectal cancer, the optimal method for LE, and the potential role for completion treatment in high-risk histology tumors and outcomes of salvage surgery.The results revealed that reported overall survival (OS) and disease-specific survival (DSS) were 71%–91.7% and 80%–94% for LE, in contrast to 92.3%–94.3% and 94.4%–97% for radical surgery. Additional analysis of National Database studies revealed lower OS with LE (HR: 1.26; 95%CI, 1.09–1.45) and DSS (HR: 1.19; 95%CI, 1.01–1.41) after LE. Furthermore, patients receiving LE were significantly more prone develop local recurrence (RR: 3.44, 95%CI, 2.50–4.74). Analysis of available transanal surgical platforms was performed, finding no significant differences among them but reduced local recurrence compared to traditional transanal LE (OR:0.24;95%CI, 0.15–0.4). Finally, we found poor survival outcomes for patients undergoing salvage surgery, favoring completion treatment (chemoradiotherapy or surgery) when high-risk histology is present.In conclusion, LE could be considered adequate provided a full-thickness specimen can be achieved that the patient is informed about risk for potential requirement of completion treatment. Early-rectal cancer cases should be discussed in a multidisciplinary team, and patient's preferences must be considered in the decision-making process.     

Patience is a virtue: Multiple preoperative visits are associated with decreased recurrence in pediatric pilonidal disease

Background/PurposeThis study aimed to compare preoperative management strategies for patients undergoing trephination for pilonidal disease and evaluate risk factors for recurrence.MethodsA retrospective review was performed of children undergoing index surgical treatment with trephination for pilonidal disease between September 2017 and April 2019. Intraoperative and postoperative management were standardized. Demographic and perioperative data were collected and analyzed.ResultsOne-hundred twenty patients were identified with a median follow-up time of 7.5 months (interquartile range 4.1–13.2 months). Overall, 24 (20%) patients had a postoperative recurrence of pilonidal disease. Patients with multiple preoperative surgery clinic visits were less likely to have recurrent disease compared to those seen only once preoperatively (11% vs 26%, p = 0.040). Compared to patients without recurrence, those who recurred went to the operating room sooner from the time of initial surgical consultation (32 days vs 54 days, p < 0.001). Perioperative antibiotics, history of acute infection, and prior drainage procedures were not risk factors for recurrence.ConclusionsMultiple preoperative clinic visits are associated with a lower recurrence rate in children undergoing trephination for pilonidal disease. An increased duration of preoperative medical management may be responsible for this finding. Prospective study is needed to confirm these findings and identify additional factors that influence recurrence.Type of StudyTreatment Study.Level of EvidenceIII (Retrospective Comparative).

Mulibrey nanism: Three additional patients and a review of 39 patients

We report on 3 patients with Mulibrey nanism (MN), or Perheentupa syndrome: the first 2 sibs from Argentina and a new patient from Spain. All 3 patients had growth failure, short stature, abnormal pigmentary retinal changes, and a J-shaped sella turcica. These findings are considered major criteria of MN. Two had pericardial constriction, which is a frequent and lifethreatening abnormality in this syndrome. MN is a rare autosomal recessive condition. Reviewing the 39 patients described so far, we have classified the anomalies into the very frequent (present in more than 66%), frequent (in at least 25%), and not frequent. Identifying the anomalies specific to MN should help its early diagnosis and treatment. © 1995 Wiley-Liss, Inc.     

Molecular characterization and genetic variation of the VP7 gene of human rotaviruses isolated in Paraguay

Rotavirus is the main cause of acute diarrhea in infants and young children worldwide. In Paraguay, acute diarrhea ranks fourth among the causes of mortality in children under 4 years of age. Rotavirus was detected in 93 out of 410 patients admitted to three main hospitals in Asunción, Paraguay from August 1998 to August 2000. Samples from 64 patients were analyzed by RT-PCR for G and P typing. G4P[8] (46.9%; 30/64) was the most common strain detected, followed by G9P[8] (17.2%; 11/64) and G1P[8] (10,9%; 7/64). Since G4 was predominant during the epidemiological peaks of 1998 and 1999, four samples were sequenced and all grouped into sublineage Ic. This sublineage was reported for the first time in 1998 in Argentina, southern border of Paraguay, and it was shown to be responsible for the increased prevalence of G4 during the epidemiological season of 1998 in that country. In addition, Paraguayan G1 strains grouped in different lineages (I and II). However, G9 was predominant during the rotavirus epidemiological peak of 2000, and phylogenetic analysis of five samples grouped into a common emergent/reemergent lineage that circulates worldwide. Since vaccination could reduce the severity and the number of cases of rotavirus disease, this study suggests that a vaccine containing recently isolated variants of the most prevalent types (G1-G4) together with the emerging G9 type, might be sufficient to elicit a protective immune response against the rotavirus types circulating currently in Paraguay.
