ABSTRACT

INTRODUCTION: Human intestinal spirochetosis (HIE) is a poorly studied clinical entity with variable clinical manifestations. However, in recent years it has gained special relevance because an increasing number of cases have been described in people living with HIV (PWH) and in patients with a history of sexually transmitted infections (STI) or immunosuppression. METHODS: Retrospective review of all HIE cases identified in a tertiary level hospital (Hospital Universitario la Paz, Madrid) between 2014 and 2021. RESULTS: 36 Cases of HIE were identified. Most cases corresponded to males (94%) with a median age of 45 years. 10 patients (29.4%) were PWH and 20 (56%) were men who had sex with men. Although the clinical manifestations were very heterogeneous, the most frequent was chronic diarrhea (47%), and up to 25% of the subjects had clinical proctitis. 39% percent of patients had been diagnosed with an STI in the previous two years, this characteristic being more frequent in PWH (90% vs. 28%; p < 0.01) than in patients without HIV infection. The STI most frequently associated with a diagnosis of HIE was syphilis (31%). CONCLUSION: HIE is frequently diagnosed with other STIs and affects mostly men who have sex with men, which supports that this entity could be considered as a new STI.

ABSTRACT

Background: The prognosis of patients with stage II and stage III colon cancer is heterogeneous. Clinical and pathological characteristics, such as tumor budding, may help to further refine the recurrence risk. Methods: We included all the patients with localized colon cancer at Hospital Universitario La Paz from October 2016 to October 2021. We built a prognostic score for recurrence in the training cohort based on multivariate cox regression analysis and categorized the patients into two risk groups. Results: A total of 440 patients were included in the training cohort. After a median follow-up of 45 months, 81 (18%) patients had a first tumor recurrence. T4, N2, and high tumor budding remained with a p value <0.05 at the last step of the multivariate cox regression model for time to recurrence (TTR). We assigned 2 points to T4 and 1 point to N2 and high tumor budding. Forty-five percent of the patients were assigned to the low-risk group (score = 0). Compared to the high-risk group (score 1−4), patients in the low-risk group had a significantly longer TTR (hazard ratio for disease recurrence of 0.14 (95%CI: 0.00 to 0.90; p < 0.045)). The results were confirmed in the validation cohort. Conclusions: In our study, we built a simple score to predict tumor recurrence based on T4, N2, and high tumor budding. Patients in the low-risk group, that comprised 44% of the cohort, had an excellent prognosis.

ABSTRACT

INTRODUCTION: Piriform fossa sinus tracts (PFSTs) are a cause of recurrent neck infections in the pediatric population. Conventional management required open resection, but over the last years minimally invasive approaches have been reported in an attempt to endoscopically obliterate the PFST, using different methods such as electrocautery, laser, trichloroacetic acid, or silver nitrate. MATERIALS AND METHODS: We undertook a retrospective review of the medical records of 12 children (aged 4 months to 14 years) with PFSTs treated with endoscopic sclerosis with diathermy (ESD) between 2010 and 2016 at a tertiary care children's hospital. We also present a technical modification of ESD, using continuous infusion of airflow through the gastroscopy, to distend the piriform sinus and facilitate its recognition. PFST obliteration was performed using diathermy through a guide wire. RESULTS: Clinical presentation of the 12 affected children included neck tumor (7 [58%]), neck abscesses (4 [33%]), and thyroiditis (5 [41%]). All lesions occurred on the left side. All patients underwent both ultrasonography and barium esophagography (the latter being positive only in 50%). Two patients were treated with ESD after the open approach had failed. There was no procedure-related morbidity. One patient had a recurrence (positive barium swallow without symptoms). The success rate of this procedure in our series was 91% with one attempt and 100% with two attempts. CONCLUSION: In our experience, treatment of PFST with ESD is a reproducible, noninvasive, and an effective option. ESD could be considered a primary approach and also for revision after open surgery has failed in these patients.

ABSTRACT

Bleomycin-induced flagellate erythema is a rare but typical skin toxicity of bleomycin. We report the case of a boy with a left foot venous malformation who developed this skin rash after two sessions of bleomycin intralesional injection. We discuss the mechanism and characteristics of this reaction to bleomycin, which is usually benign and self-limited. We conclude that, although rare, flagellate pigmentation can occur when bleomycin is used as a sclerosant in children.
