Fingertip injuries

Background:

Fingertip injuries are extremely common. Out of the various available reconstructive options, one needs to select an option which achieves a painless fingertip with durable and sensate skin cover. The present analysis was conducted to evaluate the management and outcome of fingertip injuries.

Materials and Methods:

This is a retrospective study of 150 cases of fingertip Injuries of patients aged six to 65 years managed over a period of two years. Various reconstructive options were considered for the fingertip lesions greater than or equal to 1 cm². The total duration of treatment varied from two to six weeks with follow-up from two months to one year.

Results:

The results showed preservation of finger length and contour, retention of sensation and healing without significant complication.

Conclusion:

The treatment needs to be individualized and all possible techniques of reconstruction must be known to achieve optimal recovery.     

Surgical strategies for giant medial sphenoid wing meningiomas： a new scoring system for predicting extent of resection

BACKGROUND：Surgical management of giant medial sphenoid meningiomas （〉 or =5 cm in maximum dimension） is extremely challenging due to their intimate relationship with vital neural structures like the optic nerve, cranial nerves of the cavernous sinus and the cavernous internal carotid artery. Their surgieal management is presented incorporating a radiological scoring system that predicts the grade of tumour excision. MATERIALS AND METHODS： 20 patients of giant medial sphenoidal wing meningioma （maximum turnout dimension range： 5.2 to 9.5 cm; mean maximum dimension = 6.12 ＋/- 1.06 cm） with mainly visual and extraoeular movement deficits, and raised intraeranial pressure, underwent surgery.     

Postoperative coagulopathy after live related donor hepatectomy: Incidence,predictors and implications for safety of thoracic epidural catheter

Background:

Coagulopathy after living donor hepatectomy (LDH) may endanger donor safety during removal of thoracic epidural catheter (TEC). The present study was conducted to evaluate the extent and duration of immediate postoperative coagulopathy after LDH.

Materials and Methods:

A retrospective analysis of perioperative record of LDH over three years was conducted after IRB approval. Variables such as age, gender, BMI, ASA classification, liver volume on CT scan, preoperative and postoperative INR, platelet count (PC) and ALT of each donor for five days was noted. In addition, duration of surgery, remnant as percentage total liver volume (Remnant%), blood loss, day of peak in PC and INR were also noted. Coagulopathy was defined as being present if INR exceeded 1.5 or platelet count fell below 1 × 10⁵/mm³ on any day. Data was analyzed using SPSS 20 for Windows. Between group comparison was made using the Student ‘t’ test for continuous variables and chi square test for categorical variables. Univariate analysis was done. Multiple logistic regression analysis was used to find independent factor associated with coagulopathy.

Results:

Eighty four (84) donors had coagulopathy on second day (mean INR 1.9 ± 0.42). Low BMI, % of remnant liver and duration of surgery were independent predictors of coagulopathy. Right lobe hepatectomy had more coagulopathy than left lobe and low BMI was the only independent predictor. There was no correlation of coagulopathy with age, gender, blood loss, presence of epidural catheter, postoperative ALT or duration of hospital stay. High INR was the main contributor for coagulopathy.

Conclusions:

Coagulopathy is seen after donor hepatectomy. We recommend removal of the epidural catheter after the fifth postoperative day when INR falls below 1.5.KEY WORDS: Live related donor hepatectomy, postoperative coagulopathy, thoracic epidural anaesthesia     

Relapse of Wegener's granulomatosis in the first trimester of pregnancy: a case report

The association of Wegener's granulomatosis and pregnancy is rare and poses unique therapeutic challenges, particularly when active disease presents in early pregnancy. We describe a 22-yr-old woman who recovered successfully from her initial episode of Wegener's granulomatosis with a standard course of treatment with prednisolone and cyclophosphamide. Two and a half years later, she presented with relapse during the first trimester of pregnancy (primigravida). Since the clinical features suggested mild disease, she was started on prednisolone at a dose of 1 mg/kg/day, to which she seemed to respond very well for 3 months. Unfortunately, she had a spontaneous abortion at 5 months of gestation while on 25 mg/day of prednisolone. At this time, her disease flared further, with clinically manifest lung disease which was not part of her initial presentation. She was treated with another course of oral cyclophosphamide and prednisolone, and a remission was achieved in 4 months. There are no agreed guidelines on the treatment of Wegener's granulomatosis during pregnancy. In this report, the therapeutic issues are discussed against the background of the available literature.      

Double-balloon enteroscopy and capsule endoscopy have comparable diagnostic yield in small-bowel disease: a meta-analysis

BACKGROUND & AIMS: The aim of this study was to compare the diagnostic yield of capsule endoscopy (CE) with double-balloon enteroscopy (DBE) in small-bowel (SB) disease using meta-analysis. METHODS: We performed a search of studies comparing CE with DBE in SB disease. Data on diagnostic yield of CE and DBE were extracted, pooled, and analyzed. The weighted incremental yield (IY(W)) (yield of CE--yield of DBE) of CE over DBE and 95% confidence intervals (95% CIs) for pooled data were calculated using a fixed-effect model (FEM) for analyses without, and a random-effect model (REM) for analyses with, significant heterogeneity. RESULTS: Eleven studies compared CE and DBE; the pooled overall yield for CE and DBE was 60% (n = 397) and 57% (n = 360), respectively (IY(W), 3%; 95% CI, -4% to 10%; P = .42; FEM). Ten studies reported vascular findings; the pooled yield for CE and DBE was 24% (n = 371) and 24% (n = 364), respectively (IY(W), 0%; 95% CI, -5% to 6%; P = .88; REM). Nine studies reported inflammatory findings; the pooled yield for CE and DBE was 18% (n = 343) and 16% (n = 336), respectively (IY(W), 0%; 95% CI, -5% to 6%; P = .89; FEM). Nine studies reported polyps/tumors; the pooled yield for CE and DBE was 11% (n = 343) and 11% (n = 336), respectively (IY(W), -1%; 95% CI, -5% to 4%; P = .76; FEM). CONCLUSIONS: CE and DBE have comparable diagnostic yield in SB disease, including obscure gastrointestinal bleeding. CE should be the initial diagnostic test because of its noninvasive quality, tolerance, ability to view the entire SB, and for determining the initial route of DBE. Because of its therapeutic capabilities, DBE may be indicated in patients with a positive finding on CE requiring a biopsy or therapeutic intervention, if suspicion for a SB lesion is high despite a negative CE, and in patients with active bleeding.     

Off-label abuse of antibiotics by bacteria

Antibiotics and antibiotic resistance made news on several fronts in the past year. Many public health organizations, including the CDC, used terms such as “crisis”, “catastrophic consequences”, and “nightmare scenario” to highlight the rapid emergence and spread of antibiotic resistance. A report from the Pew Commission on Industrial Farm Animal Production, on the fifth anniversary of the publication of its landmark 2008 report, noted that state and federal legislative efforts to limit non-therapeutic use of antibiotics in animal production were thwarted by drug and food animal industries. In its lobbying disclosures, the Farm Bureau stated that such efforts to limit use of animal antibiotics were “based on emotion and no credible peer reviewed science.” Meanwhile, there have been inexorable advances in our understanding of the molecular mechanisms by which antibiotics induce diversity and resistance in bacteria. This article reviews one study that probed the role of the bacterial general stress response in sub-inhibitory antibiotic-induced mutagenesis and antibiotic resistance.
