Effect of cementing technique on aseptic stem loosening in cemented primary total hip arthroplasty: a systematic review and meta-analysis.

Aseptic stem loosening after total hip arthroplasty surgery is the commonest complication, whether stem is cemented or uncemented. The aseptic cemented stem loosening has been a challenging problem over the years and a leading cause for revision since the inception of total hip arthroplasty. The objective of systematic review and meta-analysis was to determine the impact of cementing technique on aseptic stem loosening in total hip arthroplasty. Methods: Cochrane, CINAHL, Embase, Google scholar, Medline, PubMed were searched in 13 December 2020. Two independent investigators extracted the data and a third investigator's involvement was reached on consensus. A total of 37 studies of revision rate due to aseptic loosening were reviewed by using fixed/random effects size and were grouped by cementing technique and studies' characteristics. The data were analyzed through Meta-Essentials and RStudio. Results: In revision total hip arthroplasty, retained femoral components revisions rate due to aseptic loosening were recorded in 37 studies involving 6167 cases. Aseptic loosening rate collectively was 5.8% (CI 95%, 0.03-0.08) and mean follow-up of study was 12.5 years. The average follow-up period, mean age at index revision surgery and percentage of aseptic loosening were insignificantly associated with revision rate (P≥0.05), in meta-regression univariant analyses. Conclusion: This investigative analysis showed that there is a minimal difference between results of cementing techniques of total hip arthroplasty in femoral components in long-term follow-ups, and usually have a low risk of failure.

Prediction of Covid-19 infection severity using ABO blood group types and Rh factor.

Background & Objective: Biological markers for the prediction of acquiring Covid-19 risk are deficient and there is a dire need of immediate research data. The objective of the study was to predict the link of ABO blood group types along with Rh factor distribution with the severity of Covid-19. Methods: This was an observational cross-sectional survey conducted in medicine department of Pakistan Ordnance Factory Hospital, Wah Cantt Pakistan, from August 2020 to December 2020 after approval of IRB. Participants tested positive for presence of Covid-19 infection by polymerase chain reaction (PCR) were included in the study. Covid-19 infection severity was measured through mild, moderate and severe disease categories and analyzed. ABO blood group and Rh subgroups data for all the Covid-19 infected patients were obtained from the laboratory section of the hospital and analyzed. Data was entered in SPSS v 26 and analyzed. Cox regression model was used to find out the severity of Covid-19. Results: Total 248 patients were included; 75% patients were male and 25% were females. The mean age of the patients was 52.77±15.58 years. A very significant association was found between ABO blood group types, Rh factor antigen and severity of Covid-19 (p=0.001). When stratified ABO, Rh antigen blood group with health status of all patients there was a very significant association between them (p=0.013). An insignificant association between male and female odds ratio of ABO blood group types but blood group B, Rh positive antigen was more susceptible in Covid-19 positive patients. Conclusion: There is a link between ABO blood group types along with Rh factor antigen (B+ and O+) with the severity of Covid-19 positive patients. ABO blood group types and Rh factor can be used as a potential marker/tool to predict the susceptibility of acquiring Covid-19 infection as well as for severity of the infection.

Management of a giant carbuncle on the posterior trunk with excision and grafting.

Carbuncle is a painful subcutaneous mass of interconnected infected hair follicles with multiple discharging sinuses. It has predisposition in conditions like diabetes, immune-compromised states, chronic skin diseases etc. The authors present a case of a 67 year old diabetic male admitted in July 2020 at Akbar Niazi Teaching Hospital (ANTH) Islamabad, with a giant carbuncle on his back. Due to its large size, systemic co-morbidity, and increased risk of complications in surgical treatment, a multi-disciplinary team approach was employed. Both general and plastic surgeons were involved, who performed excision and soft tissue coverage respectively. The aim of the surgical intervention methods, like wide excision and debridement, application of vacuum assisted wound closure (VAC), and skin grafting was to minimise the healing time and risk of development of post-operative infection. The patient was surgically managed and sent home in a good condition.

Clinical outcomes of maitland mobilization in patients with Myofascial Chronic Neck Pain: A randomized controlled trial.

BACKGROUND AND OBJECTIVE: Myofascial neck pain is a common musculoskeletal problem caused by presence of trigger points and local and referred pain patterns. Chronic neck pain is responsible for the involvement of joints, ligaments, fascia and connective tissue as well. The objective of this study was to assess the effect of Maitland mobilization in patients with myofascial chronic neck pain. METHODS: In this randomized, placebo treatment-controlled trial, 30 patients consecutively aged 25-45 years meeting inclusion criteria were isolated into two groups. The study group was treated with Maitland mobilization consistently for eight weeks while the control group got placebo treatment for a similar timeframe. Visual analog Scale (VAS), Neck disability index (NDI) and cervical range of motion (ROM) questionnaire was filled by patients before, intermediate and after the intervention to evaluate the severity of pain, functional ability and range of motion. RESULTS: Following eight weeks of treatment, when compared the post treatment effects of both groups, the significance value for VAS was 0.008, for NDI p=0.030, for Flexion p=0.573, for extension p=0.001, for right rotation p<0.001, for left rotation p=0.002, for right and left side bending p<0.001. CONCLUSION: The study concluded that Maitland mobilization grades (I-IV) are effective in reducing pain and improving functional level of NDI scale and the ranges of cervical spine in patients with myofascial chronic neck pain.

Clinical outcome of Montelukast Sodium in Children with Adenoid Hypertrophy.

BACKGROUND & OBJECTIVES: Generally, the blockage of upper respiratory tract in children is seen with the hypertrophy of adenoids and tonsils. Normally for patients with adenoid hypertrophy (AH), Adenoidectomy with or without Tonsillectomy is carried out, however it has its own complications like haemorrhage and recurrence of adenoid tissue. Consequently, therapeutic approach has increased extraordinary consideration rather than surgical procedure. The inflammatory process proposed for AH has prompted the utilization of anti-inflammatory drugs to treat this issue. The objective of this study was to assess the impacts of Montelukast sodium in children with enlarged adenoids. METHODS: A randomized controlled trail was performed from April 2018 to March 2019 in the Otorhinolaryngology clinic of Dr. Akbar Niazi Teaching Hospital, Islamabad. In this randomized, placebo treatment-controlled trial, 60 children aged 4-12 years meeting inclusion criteria were isolated into two groups. The study group was treated with Montelukast sodium 5mg consistently for three months while the control group got placebo treatment for a similar timeframe. A questionnaire was filled by parents/ guardians of every child before and after the intervention to evaluate the severity of sleep discomfort, snoring and mouth breathing. RESULTS: Following 3 months of treatment, significant reduction in size of the adenoids was seen in 76% of study group compared with just 3% of control group getting placebo treatment. CONCLUSION: Montelukast sodium seems to be effective in the reduction of the size of adenoids and improvement in clinical manifestations. It can be viewed as a viable option in contrast to surgical treatment in children with hypertrophy of adenoids.

Comparison of harmonic scalpel versus Milligan Morgan technique in haemorrhoidectomy patients.

OBJECTIVE: To compare the efficacy of harmonic scalpel versus Milligan Morgan technique in patients undergoing haemorrhoidectomy. METHODOLOGY: The comparative study was conducted at the General Hospital, Lahore, Pakistan, from March to September 2019, and comprised patients undergoing haemorrhoidectomy who were randomised into haemorrhoidectomy group A and open haemorrhoidectomy group B which was exposed to the Milligan Morgan procedure. Data was collected through a predesigned questionnaire. Data was analysed using SPSS 25. RESULTS: Of the 60 patients, there were 30(50%) in group A; 17(56.7%) males and 13(43.3%) females with an overall mean age of 44.6±7.6 years. The remaining 30(50%) patients were in group B; 19(63.3%) males and 11(36.7%) females with an overall mean age of 43.8±8.2 years. In group A, mean operative time was 20.8±2.8 minutes, while it was 26.5±2.8 minutes in group B (p=0.001). In group A, mean convalescence period was 9.7±2.9 days, while it was 13.4±3.7 days in group B (p=0.001). Group A required less time for complete wound healing compared to group B (p<0.05). CONCLUSIONS: Harmonic scalpel haemorrhoidectomy was found to be an advantageous method compared to the Milligan Morgan technique in patients undergoing haemorrhoidectomy.

Comparison of mean pain score using topical and oral metronidazole in post milligan morgan hemorrhoidectomy patient; A randomized controlled trial.

BACKGROUND AND OBJECTIVES: Milligan Morgan Hemorrhoidectomy is one of the most commonly performed surgeries. Post-operative pain is the major cause of morbidity in post hemorrhoidectomy patients. Metronidazole has an established role in relieving post hemorrhoidectomy pain. The objective was to evaluate the pain score by using topical and oral metronidazole in post Milligan Morgan hemorrhoidectomy patients. METHODS: A prospective randomized controlled trail was done in surgical departments of Akbar Niazi Teaching Hospital, Islamabad. A total of 166 consecutive patients with 3rd and 4th degree hemorrhoids were presenting in surgical OPD and who underwent Milligan Morgan hemorrhoidectomy between July 2018 and December 2018 were included in the study. Patients allocated in two groups, Group-A received topical metronidazole 10% post hemorrhoidectomy for seven days and Group-B were given oral metronidazole 400mg for 07 days. Analgesics were given on patient's requirement. Patients post hemorrhoidectomy pain was recorded by using VSA scale at baseline (1st day) and on 7th post-operative day. Data analysis was done by using SPSS 21. Pain calculated by compared in terms of mean, standard deviation between groups and independent sample T test was used. Association between demographic details like gender and ages of the patients with pain scale on 7th day was measured and chi-square distribution was used. RESULTS: Total 166 patients were included in this study. The mean ages of the patients were 44.07±10.62 years with minimum 20 and maximum 60 years. Out of 166 patients, female were 55 (33.1%) and male were 111 (66.9%). Results showed significantly lower pain in patients using topical metronidazole as compared to oral metronidazole (p=0.001). Association of pain with respect to ages was insignificant (p=0.202) whereas between genders inside the groups showed significant difference (p=0.028). CONCLUSION: These results showed that topical metronidazole significantly reduces pain in post hemorrhoidectomy patients as compared to oral metronidazole overall and even when data stratified among age, gender and type of hemorrhoids.
