Background and aim Tennis elbow is an abuse condition that out comes in pain over lateral side of elbow, provoked by activities involving gripping and manipulating objects by hand. It is frequently a consequence of participation in activities requiring repetitive manual tasks with awkward wrist positions. Tennis elbow has a variety of treatment options, starting from nonoperative treatment, including conservative treatment, bracing, and physiotherapy, to the last line of treatment being surgical intervention. Materials and methods A systemic review was performed using Google, PubMed, and Medline for a period from 2015 to 2019 comparing three methods of tennis elbow treatment: steroid injection, open surgery, and arthroscopic surgery. Results A total of 21 studies included 2055 patients treated by arthroscopic surgery. Overall, 3638 patients were treated by open surgery and 633 patients were treated by steroid injection. Conclusion This systematic review looked at high-level evidence to compare arthroscopic technique, open surgical technique, and steroid injection. There were no clinically significant differences among the three techniques (open, arthroscopic, and steroid injection) according to postoperative pain intensity (visual analog scale). Steroid injection had the least complication rate, with early return to work, but had higher recurrence rate. [ABSTRACT FROM AUTHOR]

Background& Aim: Several treatment forms have been utilized to remove the pain following laparoscopic cholecystectomy (LC), including nonsteroidal anti-inflammatory drugs, opioids and local anaesthetics, however none has elucidated harmonious effectiveness. So, this study aimed to estimate the effectiveness of intraperitoneal (IP) lidocaine with tenoxicam on relieving the pain and bowel recovery post LC. Methods: A prospective clinical trial was performed in the General Surgery department, Zagazig University Hospitals, Egypt, between March 2019-March 2020. Such study was done on 126 patients suffered from chronic calcular cholecystitis categorized into two groups: Group (A): patients underwent LC without IP lidocaine or tenoxicam and Group (B): patients underwent LC with IP lidocaine and tenoxicam. Results: There was no significant variations among both groups concerning demographic and clinical characteristics. Furthermore, there was no significant variations concerning operation time or anesthesia time. Pain control satisfaction score (PCSS) was significantly higher in Group B. Visual analogue scale (VAS) was significantly lower at Group B from two-six hours with no significant variation at eight & 12 hours at rest or movement. The time of 1st demanded analgesia was earlier in Group A and total analgesia dosage was significantly higher between Group A. Group B was significantly shorter concerning bowel sound/h, oral intake/h, ambulation/h, and hospital stay/day. The shoulder pain and nausea were significantly correlating with Group A and also vomit was higher in Group A but not statistically significant. Conclusions: IP lidocaine with tenoxicam administration is a viable alternative when seeking to alleviate postoperative pain among patients undergoing LC. [ABSTRACT FROM AUTHOR]

Background Pressure ulcers have complex etiopathogenesis. They are localized mainly in the pelvic region over the bony prominences of sacral, ischial, and trochanteric areas. The fundamental surgical treatments are debridement with excision of the underlying bursa and the involved bone tissue, followed by tissue coverage. Aim This study reports our experience in repairing pelvic pressure sores with the V-Y advancement flaps and analyzes our results in terms of morbidity and recurrence. Methods A prospective study was conducted between Jan 2013 and Dec 2015 of 15 patients (11males, 4 females), withmean age of 43.5 years, with grade IV pelvic pressur sores (9 sacral, 6 ischial). 2 ulcerswere recurrent and 13 were primary. Themean ulcer size was 11.8 × 7.1 cm. The sacral bed sores were covered by the gluteus maximus (GM) fasciocutaneous V-Y advancement flaps (2 unilateral and 7 bilateral flaps) while the ischial bed sores were covered by the biceps femoris (BF) fasciocutaneous V-Y advancement flaps in 4 cases, BF myocutaneous V-Y advancement flap in 1 case and vertical GM fasciocutaneous V-Y advancement flap in 1 case. Results All flaps survived completely with no complications in 11 patients. Complications occurred in 4 cases (26.7%); (1 hematoma, 1 wound infection, 1 small wound dehiscence (1.5 cm) and 1 distal superficial flap necrosis), all treated conservatively without necessitating 2nd operation. During the follow up period from 8 to 20 months (mean- 13.2 months) only one case of ulcer recurrence (6.7%) that was treated by re-advancement of the same flap. Conclusion We can conclude that the success of pressure ulcer surgery depends not only on the appropriate flap choice but also on patient education and compliance. However, the V-Y advancement flaps offer a reliable and robust coverage of sacral and ischial pressure sores even recurrent ones with minimal donor site morbidity, accepted rate of complications, low recurrence rate and preservation of future reconstructive options.

Sex chromosome mosaicism results in a large clinical spectrum of disorders of sexual development (DSD). The percentage of 45,X cells in the developing gonad plays a major role in sex determination. However, few reports on the gonadal mosaic status have been published, and the phenotype is usually correlated with peripheral lymphocyte karyotypes, which makes the phenotype prediction imprecise. This study was conducted on 7 Egyptian DSD patients to demonstrate the effect of sex chromosome constitution of both blood lymphocytes and gonadal tissues on the phenotypic manifestations. Conventional cytogenetic and FISH analyses of blood lymphocytes were conducted, and laparoscopy with gonadal biopsy was performed for histopathologic examination and FISH analysis. Gonosomal mosaicism was detected in 3 patients who had a non-mosaic chromosome pattern in blood lymphocytes. Two patients showed the same type of sex chromosome mosaicism in both the blood and gonadal tissues but with different distributions. Two other patients revealed a non-mosaic pattern in both tissues. The present study elucidates the importance of examining sex chromosome mosaicism in gonadal tissues of DSD patients and highlights the critical role of 45,X mosaicism which can lead to serious effects during early gonadal organogenesis. © 2015 S.
