Oxidised cellulose in musculoskeletal oncology procedure: Does it reduce postoperative blood loss?

BACKGROUND: Major musculoskeletal oncology procedures often result in perioperative bleeding. This exposes patients to allogeneic red blood cell transfusion and its potential complications, thus increasing the risk of surgical wound infection and prolonged hospital stay. This study aimed to investigate the efficacy of oxidised cellulose, a topical haemostatic agent, in reducing postoperative blood loss and its subsequent risks. METHODS: In this randomised controlled trial, 40 patients undergoing major musculoskeletal oncology procedures were assigned to control and intervention groups. Oxidised cellulose was inserted into the surgical wound after the resection's conclusion before the wound's closure to reduce postoperative bleeding for patients in the intervention group. Postoperative closed suction drain system (Redivac TM) volume, drop in haemoglobin level, allogeneic red blood cell transfusion rate, duration of surgery, and length of hospital stay were compared between the two groups. RESULTS: The postoperative Redivac volume (Control: 432 MLS vs. Intervention: 431.75 MLS), drop in haemoglobin level (Control: 3.12 g/dL vs. Intervention: 3.06 g/dL), duration of surgery (Control: 134 vs. Intervention: 156 min), and allogeneic red blood cell transfusion were lower in the intervention group (Control: 204 MLS vs. Intervention: 170 MLS), but they were not statistically significant (p > 0.05) (Control: 134 vs. Intervention: 156 min). Mean hospital stay was similar in both groups (Control: 5.45 days vs. Intervention: 5.85 days). CONCLUSION: Oxidised cellulose use does not significantly affect postoperative blood loss, the rate of allogeneic blood transfusion, and hospital stay. However, we believe its use contributes positively but not considerably towards lower postoperative blood loss in musculoskeletal oncology surgeries.

Chronic recurrent multifocal osteomyelitis of the first metatarsal bone: a case report.

We report a case of chronic recurrent multifocal osteomyelitis in a 9-year-old girl. She presented with a 9-month history of gradually worsening pain and swelling in her left foot. Non-steroidal anti-inflammatory drugs were prescribed but the symptoms persisted. She underwent curettage through a small oval corticotomy window on the first metatarsal bone. The pain and swelling improved promptly and she was able to walk without pain 2 weeks later. Curettage enabled rapid symptomatic relief and induced remission, with little risk of complications.

Is the femoral neck geometry adequate for placement of the proximal femoral nail in the Malaysian population? A review of 100 cases.

Issues that had been encountered during proximal femoral fracture fixation using proximal femoral nail include (i) the adequacy of the femoral neck width in the local population and (ii) the potential difficulty encountered during fixation in certain prefixed angles as determined by the implant. This was a retrospective, descriptive study evaluating the anterior-posterior pelvic radiographs of 100 consecutive patients, from January to August 2007, managed at University Malaya Medical Centre, Kuala Lumpur. The femoral neck width in the population studied was adequate for placement of femoral neck screw and anti-rotation pin or hip pin using the proximal femoral nail implant. (mean = 34.0 +/- 3.7 mm, min = 24.6 mm). There was no significant difference between the working area using an implant angled at 130 degrees or 135 degrees (P = 0.91). Both femoral neck width and neck shaft angle of the Malaysian population studied were not a factor influencing the placement of femoral neck lag screws and anti-rotation pin.

A Study about Co-Infection of Fungal Pathogens in Active Tuberculosis Patients.

The diagnosis of mycotic lung infection in pulmonary TB patients remains misdiagnosed because of its non-specific clinical manifestations which mimics the symptoms of TB. Physicians have to rely on the investigation but as radiology and pathology cannot probe the appropriate diagnosis, conventional microbiology or PCR testing continue as an essential mode for the diagnosis. In developing country like India PCR is not cost effective. Thus, Direct microscopy by KOH (10%), Gram's staining & Culture remains only option for identification. A three-year cross-sectional study was carried out in the Department of Microbiology, Maharishi Markandeshwar Institute of Medical Science & Research, Mullana, India from August 2015 to August 2018. On 300 LED positive sputum samples collected from previously treated cases of pulmonary TB. Early morning sputum was collected and subjected to KOH 10%, Gram's staining afterwards cultured on Sabouraud Dextrose Agar and species identification was done by LPCB preparation. In 300 LED smear positive samples, the dominant pathogens were C. albicans (43.3%), followed by C. non-albicans (26.7%), A. fumigatus (21.7%) etc. ATT administration for 5-8 months' duration of illness showed highest fungal infection (45%) and maximum growth of fungus was seen in the Autumn season (45%). The co-occurrence of fungi with tubercle bacteria adds fatal consequences thus routine screening is recommended for proper diagnosis and early treatment of mycotic infection in the patients of Pulmonary TB on ATT.

Line Immunoassay: A Rapid Test for Screening TORCH Complex in Antenatal Patients with Bad Obstetric History.

TORCH {Toxoplasma gondii, Rubella, Cytomegalovirus (CMV), the Herpes Simplex Virus (HSV)} infection causes pregnancy wastage at any stage of gestation. Serological assays can be an important tool for diagnosis. It includes ELISA which is highly specific & sensitive with certain drawbacks like time consuming and for each genus separate test have to be done. Line-Immunoassay (LIA), a newer, cheaper and reliable technique on contrary is done on single panel strip. The present retrospective study was conducted with the aim to evaluate the efficacy of Line Immunoassay for detection of TORCH IgM antibodies. A total of 630 samples from the pregnant women with Bad Obstetric History (BOH) attending OPD and IPD of Obstetrics and Gynecology Department of Maharishi Markandeshwar Institute of Medical Science & Research (MMIMSR), Mullana, Ambala, Haryana, India from 2011 to 2015 were subjected to Line-Immunoassay and ELISA for detection of IgM antibodies against TORCH agents in Department of Microbiology. The analysis for TORCH complex showed 32.85% positivity by LIA while 36.03% by ELISA. The diagnostic accuracy of LIA when ELISA considered gold standard was also exhibited which showed Sensitivity of 90.75%, Specificity of 99.75% while PPV & NPV were 99.52%, 95.05% respectively. The statistical analysis showed results were statistically insignificant (p value >0.05). Comparison of detection of TORCH IgM antibodies by ELISA & Line-Immunoassay express good sensitivity & specificity requiring significantly less time and low cost by Line-Immunoassay, concludes that Line-Immunoassay may be used as screening test.

The rate of glove perforations in orthopaedic procedures: single versus double gloving. A prospective study.

Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves worn by the surgical team were assessed after the surgery using the water-loading test. A total of 1452 gloves were tested, and the rate of perforation was 3.58%. Most of these perforations (61.5%) were unnoticed. The main surgeons had the most perforations (76.9%), followed by first assistants (13.5%) and second assistants (9.6%). Most perforations occurred at the non-dominant hand. The commonest site of perforation was the index finger followed by the thumb. Shearing force with instruments accounted for 45% of the noticed perforations. Majority of these occurred during nailing procedures (33%) and internal fixation without the use of wires (19%). Our rate of glove perforation is similar to other series. Most of them went unnoticed and were mainly due to shearing injuries rather than perforation by sharps. Therefore, there is an increased risk of contamination and break in asepsis during surgery.

The efficacy and safety of intramuscular injections of methylcobalamin in patients with chronic nonspecific low back pain: a randomised controlled trial.

INTRODUCTION: Chronic, nonspecific low back pain is a difficult ailment to treat and poses an economic burden in terms of medical expenses and productivity loss. The aim of this study was to determine the efficacy and safety of intramuscular metylcobalamin in the treatment of chronic nonspecific low back pain. METHODS: This was a double-blinded, randomised, controlled experimental study. 60 patients were assigned to either the methylcobalamin group or the placebo group. The former received intramuscular injections of 500 mcg parenteral methylcobalamin in 1 ml solution three times a week for two weeks, and the placebo group received 1 ml normal saline. Patients were assessed with Oswestry Disability Index questionnaire Version 2.0 and Visual Analogue Scale pain score. They were scored before commencement of the injections and at two months interval. RESULTS: Of the 60 patients, 27 received the placebo injections and 33 were given methylcobalamin injections. A total of 58 patients were available for review at two months (placebo: n is 26; methylcobalamin: n is 32). There was a significant improvement in the Oswestry Disability Index and Visual Analogue Scale pain scores in the methylcobalamin group as compared with the placebo group (p-value less than 0.05). Only minor adverse reactions such as pain and haematoma at the injection sites were reported by some patients. CONCLUSION: Intramuscular methylcobalamin is both an effective and safe method of treatment for patients with nonspecific low back pain, both singly or in combination with other forms of treatment.
