Sacrospinous fixation (SSF) or Richter’s intervention (RI) aims to treat genital prolapse by securing the posterior vaginal wall to the small sacrospinous ligament. It is performed by low approach and includes a dissection of the pararectal space, visual exposure of the sacrospinous ligament and a needle with strait needle holder with nonabsorbable threads. It is often associated with a more complex corrective procedure, including cystocele cure, vaginal hysterectomy and posterior myorrhaphy. The objective of this study is to report the results of SSF in the gynecology department of Hopital du Mali. A descriptive study was conducted from September 2014 to September 2015 concerning 37 patients operated on for uterine prolapse (UP). All patients with grade III UP were included in our study in whom a unilateral hysterectomy (UH) and sacrospinous fixation (SSF) were performed. All the patients were scheduled. Preoperatively they had benefited from an assessment and a pre-anesthetic consultation. Hospitalization of at least 24 hours prior to the operation was required. Postoperative follow-up was two years with a physical examination at 3 months, 9 months and 15 months, and phone calls between physical consultations. During the study period, we performed 37 RIs. The mean age of the patients was 48 years with extremes of 41 to 73 years. The large multiparity was found out in 35 cases (94.59%), the pauciparous were two with 3 deliveries for each. Long labor of more than 18 hours was found out in 9 patients (24.32%) and home delivery in 13 cases (35.13%). The duration of the occurrence of prolapse was at least two years and 35 patients were going through menopause. The type of anesthesia used for the surgery was spinal anesthesia for all patients. The average duration of the operation was 90 minutes. Complications occurred in three patients or 8.10% of cases, two cases of acute urine retention and one case of hematoma of the para-rectal space. The medium time of hospital stay was 5 days. The anatomical result was satis 展开更多

Infertility is a socio-cultural drama in Africa, especially in Mali and remains difficult for couples to overcome. Laparoscopy, also called minimally invasive surgery or keyhole surgery, is an operative technique that permits to explore the pelvis and perform an appropriate therapeutic procedure. The objective of our work was to assess the role of laparoscopic surgery in the treatment of female infertility at Hopital du Mali. It was a retrospective descriptive study that was conducted over a period of 5 years (January 2013 to December 2018). Any patients followed for infertility and who underwent laparoscopic surgery in the gynecology department over a period of two (2) years were included. The outcome of laparoscopic surgery was evaluated in terms of conception of pregnancy. We had collected 103 infertile patients out of 2984, with a frequency of 3.45%. The mean age of our patients was 30.2 years. Housewives and out-of-school women accounted for 68.93% and 54.37% respectively. Nulligravida represented 41.75%. Regarding infertility, it was primary in 41.75% and secondary in 58.25%, with an average duration of 6.2 years. Systematic chlamydial serology was positive in 62.14% of our patients. Hysterosalpingography (HSG) revealed bilateral tubal obstruction in 53.33% of cases. Laparoscopy found tubal adhesions in 97.80% of cases. Adhesiolysis was the main procedure performed with 84.47% bilateral tubal patency achieved in the methylene blue test. Among our patients who had contracted a pregnancy (22.99%), 85% had carried their pregnancies to term. Tubal damage was the main cause of infertility. Adhesiolysis remains the main laparoscopic procedure for treatment. 展开更多

The TCM philosophy of a meridian and associated channels pertains to the specific function of one or more organs. We define the <span style="font-family:Verdana;">Lung Primary Meridian (LUM) together with the </span><span style="font-family:Verdana;">Lung Sinew (LUSC), Divergent (LUDC), Luo-connecting (LULCC) Channels as a system of routes plus some parts of the body (such as muscles) to fulfil respiration, as a main function under different situations. There is very limited information about the Lung associated channels in classical literature of TCM. With a clear focus on the function of respiration, we have carried out a detailed analysis of the biomedical consequence of stimulating the LUM, analysed the roles played by LUSC, LUDC, and LULCC. The updated LUM and LUDC include acupoints of other meridians, serving the same purpose of performing satisfactory respiration starting from checking the quality of the inflow through the nose. The LUSC includes the respiratory muscles (plus the associated connective tissues) extending to various parts of the body. The muscles of the limb (as part of the LUSC) embrace the nerves that provide routes for somatosensory reflexes and play the role of locomotion, providing voluntary respiration via the pectoralis muscles. The muscles of LUSC are bounded by stiff connective tissue layers, forming compartments, and are part of the pulley system for various body locomotions. Within a compartment, the interstitial fluid, blood, lymph flows must be potent to protect the associated nerves related to LUM;the healthy state of the LUSC also provides freedom of various types of locomotion. The LULCC exists because the vagus nerve has a part of it passing through the spinal cords all the way down to the sacrum domain, with exiting nerve innervating two-third of the large intestine. The crucial steps of our deductions </span><span style="font-family:Verdana;">are supported by experimental evidence based on modern neurophysiology and kinesiology.

This article aims to provide some thoughts on the prevention and treatment of Coronavirus Disease 2019(COVID‑19)from the perspective of JingFang Medicine(Classical Chinese Formula).It is believed that the vague theoretical understanding of COVID‑19 in Traditional Chinese Medicine does not hinder the precise treatment of the disease by following the rule of“With this Zheng,prescribe this Fang.”According to the principle of“Fang‑Zheng Correlation”and the knowledge gained from the thousands of years of experience in treating febrile diseases,Xiao Chai Hu Decoction(小柴胡汤)and its modifications are recommended with the emphasis on individualized treatment.As another form of practicing“Fang‑Zheng Correlation,”generalized group treatment should also be paid attention to.Giving considerations to the historical medical data,Jing Fang Bai Du Powder(荆防败毒散)and Shi Shen Decoction(十神汤)are recommended for group prevention treatment.Assisting the Zheng(Upright)Qi and using tonic formulas are two entirely different concepts.According to the principle of“Fang‑Zheng Correlation,”tonics abuse should be avoided in the prevention of COVID‑19,and the using of Huang Qi(黄芪Radix Astragali seu Hedysari)should also be very carefully done. 展开更多
