Epstein-Barr virus (EBV)-associated lymphoepithelioma-like gastric carcinoma (LELC) is characterized by a lower lymph node (LN) metastasis rate and a higher survival rate than other forms of gastric cancer. Although current prognosis for LELC is favorable, the most common approach is radical gastrectomy involving an extensive D2 lymph node dissection. Here, we report four cases of EBV-associated early LELC that were treated by an alternative approach, endoscopic submucosal dissection (ESD). The long-term outcome of this procedure is discussed. All patients were treated by ESD en bloc, and all ESD specimens showed tumor-free lateral resection margins. None of the lesions showed lymphovascular invasion. A pathological examination of ESD specimens revealed submucosal invasion of more than 500 μm in all four cases. One patient underwent additional radical surgery post-ESD; no residual tumor or LN metastasis was noted in the surgical specimen. The other three patients did not undergo additional surgery, either because of severe comorbidity or their refusal to undergo operation, but were subjected to medical follow-up. None of the ESD-treated patients reported local recurrence or distant metastases during the 27-32 mo of follow-up after ESD.

Analysis of eye diseases of patients at Kasungu District Hospital in Malawi was made. Malawi is one of the poorest countries in the world and the health system faces a lot challenges in terms of resources. The study was, therefore, done to understand the burden and distribution of eye diseases in this resource-limited setting. A retrospective study was conducted by extracting data from data registers in the outpatient eye department for the period of May 2015 to june 2016. The data of the reported eye diseases analyzed with variables such as patient gender, eye disease type, patient age and times of the year. There was no association between eye diseases and gender nor with times of the year. However, it was noted that the commonest type of eye disease was conjunctivitis. And, there was strong association of some disease type with age, for example, conjunctivitis was common in young age group while cataract was common in the elderly. It was shown in this study that many of the eye diseases endemic in Africa do generally occur in this selected district as well. However, the analysis presents the possibility of reducing the incidences of many diseases by preventive measures and access to health facilities on time.
