To describe a newly modified laparoscopic presacral neurectomy procedure and to evaluate the long-term benefits of the surgery as a treatment for midline dysmenorrhea. Eighty-eight reproductive female patients with midline dysmenorrhea were enrolled in the non-randomized prospective study. There were fifty-five patients in the modified laparoscopic presacral neurectomy (MLPSN) group and thirty-three patients in the conventional laparoscopic presacral neurectomy (LPSN) group. All patients received post-surgery follow-up of more than eight years for evaluation with respect to pain relief, recurrence, and complications. Upon receipt of surgery, the MLPSN and the LPSN groups both demonstrated a significant decrease (P<0.001) in the mean pain score when compared to the pre-surgery mean pain scores. However, the probability of recurrence during the eight years of follow-up was 81.8% (27 patients) in the LPSN group, compared to 43.6% (24 patients) in the MLPSN group, resulting in a significantly lower long-term recurrence rate in the MLPSN group, compared to the LPSN group (P<0.05). No patients in the MLPSN group had long-term complications and one patient had constipation after surgery in the LPSN group. The modified laparoscopic pre...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.
