Background: Deltoid fibrosis is part of a spectrum of fibrous conditions that affects both function and cosmetic surgery. Objectives: Describing anatopathology injury of fibrous deltoid muscle, and evaluating relationship between pathological anatomy and surgical technique. Subject and methods: A prospective study was undertaken to evaluate the relationship between pathological anatomy and surgical technique, which were performed from April 2006 to May 2007. The study included 279 children (102 female, 177 male); age range from 5 years old to 18 years old. Clinical examination, X-ray and ultrasound techniques were performed. Patients were operated with insertion or distal fibrous portion release. Results: The dimpling of the skin, the palpable fibrous band resolved completely in all of them. Subluxation of scapula - humeral joint in 62.4%, abducent angle more than 25 degrees in 81.3%; Adduction angle more than 15 degrees in 94.5%; and Hung NN angle less than 20 degrees in 96.4%. Droop of acromion in 74% and narrowing Scapulo - Humeral joint in 100%. Postoperative complication with dimpling of the skin or staircase like deformity and loss of the natural roundness of the lateral aspect of the shoulder in 33.5%. Conclusions: Pathological anatomy of fibrous deltoid muscle related surgical technique and postoperative complications. The big breadth and diameter of fibrous portion could create a dimpling of the skin or loss of the natural roundness of the lateral aspect of the shoulder.

Background: Nowadays, bleeding due to rupture of esophageal vein is common severe complication of portal hypertension syndrome. Spleno-renal vein anastomoses are useful procedure in the prevention of recurrent bleeding but there are some disadvantages. Objectives: To evaluate results of splenectomy, spleno-renal vein anastomoses in the prevention of recurrent bleeding due to portal hypertension at GI Emergency Department, Viet Duc Hospital. Subjects and method: This intervention study was carried out on 34 patients with bleeding due to rupture of esophageal vein in cirrhosis and portal hypertension. All patients underwent splenectomy, spleno-renal vein anastomoses. Mortality rate, recurrent bleeding, and anastomotic flow were assessed. Results and Conclusion: 34 patients (29 males and 5 females) with Child A and B cirrhosis underwent splenectomy and spleno-renal vein anastomoses. These procedures can prevent 88% of recurrent bleeding due to rupture of esophageal vein in cirrhosis and portal hypertension after 18 months of follow-up. 12% patients had recurrent bleeding. The number of patients with postoperative hepato-cerebral syndrome was small. The anastomotic stricture rate was suitable.

Epidural fibrosis is a contributing factor to the persistent pain that is associated with failed back surgery syndrome (FBSS) and other pathophysiologies, particularly as it inhibits the passage of regional medications to areas responsible for pain. Therefore, effective mechanical detachment of epidural fibrosis can contribute to pain reduction and improve function in FBSS patients. In this report, we describe the successful treatment of FBSS patients with epidural adhesiolysis using a Fogarty catheter via the transforaminal approach.

Lip canting is associated with facial asymmetry, and is one of the most challenging problems in surgical correction of facial deformities. The author corrected lip canting using bioabsorbable devices during orthognathic surgery. Soft tissue suspension procedures were performed on four patients with facial asymmetry. Lip lines improved for all patients. Over an observation period of five years, no complications were noted, nor did any late relapse develop. Furthermore, as time past, the effect of the Endotine suspension procedure increased probably due to induction of fibrosis on surrounding soft tissues.

Using a rabbit model, we assessed the postoperative status and histopathologic findings of superior oblique tenotomy with silicone expander procedure. In the control group we marked and cut the superior oblique, and in the experimental group we inserted a silicone 240 retinal band 4 mm in length along the edges of incision. At the postoperative weeks 1,3,5 and 7, we randomly chose five rabbits and made a histopathologic examination after hematoxylin-eosin and Masson's trichrome stain. The distance between the incised edges was various in the control group, but constant in the experimental group. With time inflammation decreased and fibrosis of the superior oblique increased. Foreign body reaction occurred around the suture material in both groups., but not around the silicone expander. At 5 weeks atrophy of the superior oblique was observed in both groups.From the above results, we concluded that the superior oblique lengthening procedure using silicone expander is a useful surgical method for weakening the superior oblique muscle.

OBJECTIVETo evaluate the histopathological characteristics and clinical implication of sarcolemma tissue in prepubertal concealed penis.

METHODSAfter measurement of the penile length, 10 prepubertal children with congenital concealed penis underwent modified Devine's operation (treatment group), and another 10 normal prepubertal children received circumcision (control group). The anatomic features of the penile sarcolemma tissue was observed intraoperatively, and its fibrosis was evaluated by Masson trichrome staining.

RESULTSThe penile length of the treatment group was significantly shorter than that of the control group preoperatively ([1.49 +/- 0.17 ] cm vs [4.26 +/- 0.23 ] cm, P < 0.01). The degree of penile concealment was correlated with the distal point of the attachment of its sarcolemma fibrous tissue: the closer the distal attachment point was to the coronary ditch, the more serious was penile concealment. The proportion of the area of collagen fibers in the penile sarcolemma tissue was significantly higher in the treatment group than in the control ([65.6 +/- 6.9]% vs [37.1 +/- 4.7]%, P < 0.01).

CONCLUSIONSarcolemma fibrosis was obvious in congenital concealed penis, and the key to its management is drastic removal of all the fibrous sarcolemma tissue.

Idiopathic Pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic interstitial lung disease with unknown cause, which is closely related to lung cancer. A serious complication called Acute exacerbation of IPF (AE-IPF) is prone to occur after lung resection. It progresses rapidly without effective treatment and has a poor prognosis. A typical case of AE-IPF after lung cancer surgery was reported, and its clinical characteristics, imaging features, diagnosis and treatment were summarized.

OBJECTIVE: Epidural fibrosis and adhesion are the main reasons for post-laminectomy sustained pain and functional disability. In this study, the authors investigate the effect of irradiated freeze-dried human amniotic membrane on reducing epidural adhesion after laminectomy on a rat model. METHODS: A total of 20 rats were divided into two groups. The group A did not receive human amniotic membrane implantation after laminectomy and group B underwent human amniotic membrane implantation after laminectomy. Gross and microscopic findings were evaluated and compared at postoperative 1, 3 and 8 weeks. RESULTS: The amount of scar tissue and tenacity were reduced grossly in group of rats with human amniotic membrane implantation (group B). On a microscopic evaluation, there were less inflammatory cell infiltration and fibroblast proliferation in group B. CONCLUSION: This experimental study shows that implantation of irradiated freeze-dried human amniotic membrane reduce epidural fibrosis and adhesion after spinal laminectomy in a rat model.
