Post-Traumatic Radial Artery Pseudoaneurysm at the Wrist Level: A Case Report

A pseudoaneurysm is a collection of blood outside the arterial lumen but remains in continuity with the lumen and lined by fibrous tissue. Radial artery pseudoaneurysm is a rare entity mostly occurring due to iatrogenic reasons. Traumatic causes are rare. In this case report, we report a post-traumatic left radial artery pseudoaneurysm at the wrist level in a 20-year-old male patient. The patient was treated with end-to-end repair of excised pseudoaneurysm with a vein graft taken from the radial artery vena comitantes through the same incision.

Early Reconstruction with Locoregional-Free Flaps in Post-COVID-19 Rhino-orbital-cerebral Mucormycosis Craniofacial Deformities: A Single-Center Clinical Experience from India

Aim of the Study  Mucormycosis is a rare invasive and fatal fungal infection and its resurgence in coronavirus disease 2019 (COVID-19) patients has been a matter of grave concern. It is essentially a medical disease, but surgical debridement of necrotic tissues is of paramount importance leading to severe craniofacial deformities. In this case series, we present our experience with the feasibility of early reconstruction after surgical debridement. Case Series  As a Dedicated COVID Center (DCH), the institute received the largest population of COVID-19 mucormycosis patients from the entire eastern region of the country between May 2021 and August 2021. More than 5,000 COVID-19 were admitted out of which 218 patients were diagnosed with mucormycosis. Nine patients, seven males and two females, with a mean age of 39 years with craniofacial mucormycosis underwent debridement and early reconstructions (2-4 weeks from first debridement and start of antifungal therapy) with free and pedicled flaps. All flaps survived and showed no evidence of recurrence. The average time of the early reconstruction after surgical debridement was 1.7 weeks once the course of systemic amphotericin B was received. Conclusion  After aggressive surgical resection and a short course of antifungal therapy, early reconstruction can be done safely based on clinical criteria, as long as there is no evidence of hyphae invasion on wound edges in the intraoperative pathology examination.

A Unique Case of Venous Coupler Disruption and Salvage of Venous Anastomosis in a Case of Free Latissimus Dorsi Flap Reconstruction

Free flaps are considered the gold standard for the reconstruction of various defects. Microvascular anastomosis is a very critical component of free flap surgery determining its success. The workhorse technique of hand suturing for microvascular anastomosis has consistently been used with excellent results. Recently, venous couplers are being increasingly used for performing venous anastomosis. We describe the case of a 14-year-old girl in which heel reconstruction was planned for an unstable scar and chronic osteomyelitis of the calcaneal region with a free latissimus dorsi muscle flap. Arterial anastomosis was done by hand suturing, while venous coupler (GEM coupler, Synovis Micro Companies Alliance) was used for venous anastomosis. Just before wound closure, the venous coupler spontaneously snapped open, resulting in disruption of the device and opening of the anastomosis. After securing hemostasis, the ring of the coupling device was tried to be removed, but it was adhered to the tunica externa due to the interlocking pins. Cutting the veins proximal to the rings would result in shortening of the vein with the requirement of a vein graft. The harvested latissimus dorsi muscle had a single vena comitans which had to be salvaged, so we improvised by everting the vein edges from the interlocking pins and completing the anastomosis by hand after freshening the margins. The interlocking rings were left as such in their place. Postoperative period was uneventful, and the flap survived with good results. Thus, this is a unique case where we report for the first time the disruption of a venous coupling device and subsequent salvage of free flap.

Intracoronary epinephrine during cardiac resuscitation for patients undergoing percutaneous coronary intervention for acute myocardial infarction (iCPR study)

Background

Despite significant progress in cardiopulmonary resuscitation (CPR), outcomes remain relatively poor. Epinephrine administration remains a cornerstone in the treatment of in-hospital cardiac arrest. Various routes of administration, including intravenous, intramuscular, intraosseous and endotracheal routes have been studied; however, the optimal route is debated.

Purpose

The purpose of this study was to compare patient outcomes following peripheral intravenous (IV), central IV, or arterial intracoronary (IC) epinephrine administration in patients undergoing CPR in the catheterization laboratory.

Methods

This was a prospective two-center pilot cohort study conducted in high-volume percutaneous coronary intervention (PCI) facilities in the republic of Lithuania. The study enrolled patients with acute myocardial infarction (AMI) who suffered a cardiac arrest in the cardiac catheterization laboratory during PCI. Cardiac resuscitation was performed according to the European Resuscitation Council Guidelines. Central IV was the first choice for epinephrine administration if it was available. However, in cases without central access, the route of epinephrine administration (peripheral IV or arterial IC) was at the discretion of the physician. The primary endpoint was the rate of return of spontaneous circulation (ROSC). We tested for overall differences in patient characteristics and outcomes between groups using Chi-Square (or Kruskal-Wallis) tests and used the Holm-Bonferroni adjustment (or Dunn's tests) for subsequent pairwise tests. We also performed logistic regression.

Results

There were 158 participants in this study, with 48 (30.4%), 50 (31.6%), and 60 (38.0%) receiving epinephrine via central IV, IC, and peripheral IV routes, respectively. The median age was 71 [61, 80] years and 56% of participants were men. Patient characteristics were similar across routes, except for age (higher for peripheral IV than IC), serum potassium (although no significant post-hoc differences), hemoglobin (lowest in peripheral route), and heart rhythm before CPR (higher rates of electromechanical dissociation in peripheral route). There were 111 (70%) patients who achieved the primary outcome of ROSC (Table 1). Peripheral IV administration was associated with 7-fold decreased odds of achieving ROSC (odds ratio = 0.14, 95% confidence interval = 0.05–0.36, p<0.0001) compared to central IV (no difference between central IV and IC; p=0.9343). By itself, adrenaline route yielded an area under the receiver operating characteristic curve of 0.73, indicating good predictive ability.

Conclusion

Epinephrine administration route was a significant predictor of ROSC for patients with AMI undergoing CPR in the catheterization laboratory. ROSC rates for patients who received epinephrine via IC or central IV were superior to those who received it via peripheral IV.

Approach to management of nerve gaps in peripheral nerve injuries

Peripheral nerve injuries (PNI) are a major clinical problem. In general, PNI results from motor vehicle accidents, lacerations with sharp objects, penetrating trauma (gunshot wounds) and stretching or crushing trauma and fractures. They can result in significant morbidity, including motor and/or sensory loss, which can affect significantly the life of the patient. Currently, the standard surgical technique for complete nerve transection is end-to-end neurorrhaphy. Unfortunately, there is segmental loss of the nerve trunk in some cases where nerve mobilization may permit end-to-end neurorrhaphy if the gap is less than 1 cm. When the nerve gap exceeds 1 cm, autologous nerve grafting is the gold standard of treatment. But in light of limited availability and concerned donor site morbidity, other techniques have been used: vascularized nerve grafts, cellular and acellular allografts, nerve conduits, nerve transfers and end-to-side neurorrhaphy. This review intends to present an overview of the literature on the applications of these techniques in repair of peripheral nerve injuries. This article also focuses on preoperative assessment, surgical timing, available options and future perspectives.

Medial plantar artery-based perforator and island flaps: a case series of applications in sole defects

BACKGROUND

Soft tissue defects of the plantar foot pose a challenge to the reconstructive surgeon. The plantar region of the foot has a unique skin structure, which helps in its paramount functions of weight-bearing and providing protective sensation. It is best replaced with tissue of its own kind. The medial plantar artery (MPA) flap fulfils all the requirements of an ideal replacement for small-to-medium-sized defects in the mid plantar and heel region. This study describes our experience with MPA-based flaps for small-to-medium-sized defects of the plantar foot.

METHOD

The study was conducted in a tertiary referral hospital between April 2017 and March 2020 on patients who presented with defects on the mid plantar region and heel. MPA perforator (MPAP) flap or island flap were applied. The donor site was covered with split-thickness skin grafts.

RESULTS

The study included 21 patients. MPAP flap was applied in nine patients and the island flap was applied in 12 patients. The mean age of the patients was 37.95 years and the mean flap size was 36.6cm². All flaps survived well. In two patients, venous congestion developed which resolved spontaneously, while three patients had small graft loss which also healed with conservative treatment. All patients regained protective sensation within five months of flap coverage.

CONCLUSION

Based on the MPA, both perforator and island flaps can be raised due to the fairly constant position of the perforators. These flaps have the advantage of robust vascularity with the replacement of identical tissue for weight-bearing functions along with acceptable aesthetic outcomes. Since they also have the added advantage of conferring sensation, they can be used as a primary option in cases of small-to-medium-sized plantar foot defects.

The prognostic value of the basal SYNTAX score I after early percutaneous coronary intervention using second generation drug eluting stents in patients with ST elevation myocardial infarction

Introduction

The SYNTAX score is an angiographic tool used to grade coronary artery disease (CAD) burden and complexity. SYNTAX score predicts 1-year adverse outcomes for patients with multivessel and/or left main CAD who undergo percutaneous coronary intervention (PCI). However, the relationship of the pre-PCI (basal) SYNTAX score to long-term outcomes of patients with ST-elevation myocardial infarction (STEMI) treated with primary PCI is unknown.

Purpose

To evaluate the short-term (in-hospital) and long-term (5-year) prognostic value of basal SYNTAX score in patients with STEMI who were treated with primary PCI.

Methods

We retrospectively reviewed records of consecutive patients presenting with STEMI, admitted from January 2014 to December 2016, who underwent primary PCI. We categorized patients into two groups according to SYNTAX scores: low/intermediate (≤22, 23–32) and high (>33). We utilized the Cochran-Armitage test for trend, Chi-square test, Fisher's Exact test, and Kruskal-Wallis tests to assess differences in baseline characteristics and outcomes as appropriate. We used logistic regression and calculated the area under the receiver operating characteristic curve to determine the prognostic ability of SYNTAX score groups on 5-year outcomes for stroke, myocardial infarction (MI), cardiovascular death, target vessel revascularization (TVR), all-cause mortality, and major adverse cardiovascular events (MACE).

Results

There were 768 patients who met inclusion criteria for this study. 559 (72.8%) patients were in the low/intermediate SYNTAX score group and 209 (27.2%) patients were in the high SYNTAX score group. Baseline characteristics did not differ significantly between the two groups. In-hospital pacemaker implantation, in-hospital stent thrombosis, and in-hospital cardiac arrest and in-hospital death were rare and did not differ according to SYNTAX group (Table 1). However, the odds of experiencing stroke, MI, cardiovascular death, TVR, all-cause mortality, and MACE at 5 years were significantly higher in the high SYNTAX score group, even when adjusted for heart failure, total cholesterol, and age. The associated areas under the receiver operating characteristic curve indicated moderate-to-strong prognostic ability of the basal SYNTAX score (Table 2).

Conclusion

A high SYNTAX score in patients with STEMI who undergo primary PCI is associated poorer long-term outcomes, compared to patients with an intermediate/low score. This work confirms that a high burden of CAD in patients with STEMI portends a poorer long-term prognosis.

The reverse flow extensor digitorum brevis flap for dorsal foot defects-A single center study

BACKGROUND

Defects on the dorsum of the foot remain a reconstructive challenge for plastic surgeons. There are very few pedicled flaps that have a reach up to the distal foot and those too with a threat of poor perfusion. Very often distal foot has to be resurfaced with free flap even with small defects. This study describes our experience with the reverse extensor digitorum brevis muscle (EDB) flap for small- to medium-sized defects on the dorsum of the foot.

METHODS

The study was conducted on 12 patients between February 2018 and March 2020 who presented with defects on the dorsum of the foot. The mean age of the patients was 30.8 years and the mean defect size was 20.17 cm². The EDB was applied on 10 male and 2 female subjects and resurfaced with a split thickness skin graft. The donor site was closed primarily.

RESULTS

All flaps survived well. Two patients had small graft loss and 2 partial wound dehiscence of donor site, all of which healed on conservative treatment. Three patients had temporary sensory disturbance which resolved in few weeks.

CONCLUSION

The reverse EDB flap is a reliable flap for the coverage of small- to medium-sized dorsal foot defects. The flap has the advantage of robust vascularity, expendable muscle with little donor site morbidity, an easy to learn technique, short operating time, and acceptable esthetic outcome, and it can be used as the primary option in cases of small to medium dorsal foot defects.

Tongue-lip adhesion in Pierre-Robin sequence: Role redefined

The triad of retrognathia, glossoptosis, and airway obstruction characterizes the Robin sequence along with the detrimental effects of mandibular hypoplasia on feeding, swallowing, and growth, which are very well described. Most of the babies are managed successfully on nonsurgical measures, but selected patients require surgical intervention in the neonatal period for survival. Conventionally, tracheostomy was done, which still remains a first-line surgical procedure for some surgeons. However, presently, most of the craniofacial centers have switched over to mandibular distraction procedures at an early stage and only sometimes tongue–lip adhesion (TLA). The literature is unclear as to which surgical procedure for securing the airway is more effective for these patients, and hence, the choice of procedure depends on the resources and surgical expertise. This article tells the tale of a neonate who survived by just placing a simple U-stitch between the tongue and lip, retracting the tongue outside, which is the basic concept of all TLA procedures. It also reemphasizes the importance of TLA in Robin patients to improve the airway obstruction and helps buy the time in which the mandible and associated structures grow.

Clinical Outcome of Metacarpophalangeal Joint Dislocation of the Thumb in Children: Case Series of 10 Patients

OBJECTIVES

Dislocation of the metacarpophalangeal joint of the thumb in children is an uncommon entity. The aim of this study was to evaluate the clinical outcome of pediatric patients with metacarpophalangeal joint dislocation of the thumb.

PATIENTS AND METHODS

Ten pediatric patients with metacarpophalangeal joint dislocation of the thumb were evaluated. Patients were studied prospectively over a period of 3 years. Parameters studied included patient demographics, type of dislocation, management, and any complications.

RESULTS

Mean age of patients was 6.8 years (range: 3-12 years). Seven patients underwent closed reduction and three patients were managed by open reduction. Of the total 10 patients, excellent results were obtained in 9 patients. One of the patients who reported on the fourth day of trauma and was managed by open reduction had mild joint stiffness with a range of motion of 10 to 40 degrees at final follow-up. None of these patients had infection or instability.

CONCLUSION

After thorough clinical and radiological examination, closed reduction can be done in incomplete and simple complete dislocations of metacarpophalangeal joint of the thumb. Repeated closed reduction should be avoided in complex complete injuries. Early mobilization is advised to prevent joint stiffness.

Elderly patients have more infectious complications following laparoscopic colorectal cancer surgery

AIM

Elderly patients may be at higher risk of postoperative complications, particularly infective, than younger patients.

METHOD

We prospectively followed 163 consecutive patients undergoing elective laparoscopic resection for cancer. We compared patients < 65, 65-80 and > 80 years of age at the time of surgery.

RESULTS

Seventy (42.9%) patients had no complication; 93 (57.1%) had at least one complication following surgery and in 20 (12.3%) this was major. There was no difference in major complications between the groups (P = 0.47). Patients over 65 years of age were more likely to have a complication of any severity [< 65 years, 39.3%; 65-80 years, 69.3%; and > 80 years, 63.0% (P = 0.002)]. The frequency of gastrointestinal complications (30.1%) was similar in the groups (P = 0.29), as was wound infection (25.2%) (P = 0.65). There was an increase in the frequency of infectious complications, especially chest infection, with age, from 14.8% in patients < 65 years, to 22.7% in patients 65-80 years, to 44.4% in patients > 80 years (P = 0.01). Multivariate analysis showed no increase in overall complications in elderly patients, but Stage II or Stage III cancer (OR = 2.59, P = 0.04) and increasing body mass index (BMI) (OR = 1.07 for each unit increase in BMI, P = 0.04) were related to complications. Age remained the only predictor of an infective complication on multivariate analysis. Patients > 80 years of age had 4.21 times the OR of an infective complication (P = 0.03).

CONCLUSION

Older patients are more susceptible to infective complications postoperatively, particularly chest complications. Surgeons should alter their practice to reduce morbidity, such as adopting protocols requiring early physiotherapy.

Hand amputations: epidemiology, management and resurfacing options for soft tissue coverage

OBJECTIVE

Agricultural hand injuries occur mainly among young adults, many affecting the dominant hand, thereby impeding patients' ability to work or cope with social obligations. This study was carried out with the aim of collecting data on the epidemiology and management of agricultural hand injuries in Indian subjects.

METHOD

The study was conducted in the Department of Plastic and Reconstructive Surgery, JN Medical College, AMU, Aligarh, India, from October 2009 to December 2013. Patients with agricultural hand injuries were included. Data collected included socio-demographic details, mode and type of injury, type of reconstruction, complications, length of hospital stay and assessment of post-reconstruction status. These data were tabulated and analysed.

RESULTS

The typical patient was young (mean 33.2 years), of lower socio-economic status and with a total disregard for safety regulations. There is clustering of cases during the wheat harvest season (April-June). Wheat thresher injuries were the most common cause of partial hand amputation (51%), especially during this season. This was followed by fodder cutting (kutti/chara) machine injury, especially in females and children (36%). A simple classification for these injuries has been described and Grade II injury was the commonest. Reverse radial forearm flap was the most suitable regional flap for coverage, whereas thoraco-umbilical flap was the most commonly used distant flap. Patients who had the single-stage procedure had a significantly shorter stay.

CONCLUSION

Agricultural hand injuries are not totally avoidable and their incidence can be reduced by proper education, but the low economic and literacy status of the patients is a big hurdle. The forearm offers many flaps for reconstruction of hand, which can be used in defects on dorsal or palmar aspect of hand and results in early discharge from the hospital and early rehabilitation. In patients with associated injury to the forearm, abdominal flaps can be used for cover.

Yeast cell wall and live yeast products and their combination in broiler diets formulated with weekly ingredient variations

A 6-week broiler study was conducted to evaluate whether subjecting the intestinal microflora of broilers to the effect of weekly variations in feed ingredients could be ameliorated by the inclusion of yeast-derived feed additives: a yeast cell wall extract (YCW), live yeast culture (LY) or their combination (YCW + LY). Recent changes in ingredient prices have motivated producers to formulate diets not necessarily based primarily on corn and soya bean meal. Intestinal microflora in birds can vary significantly based on the ingredient composition of their diet, and the make-up of the flora can influence overall bird performance. Within the three nutrient phases of this study, birds were fed either a traditional corn-soya ingredient profile or a variable-ingredient regimen, which had weekly changes in the ingredient composition. There were consistent ameliorative effects of the yeast treatments in both the corn-soya and the variable-ingredient groups throughout all 6 weeks, with the YCW + LY combination showing a reduced effect when compared to either product fed alone. The effectiveness of YCW and LY on ameliorating the effects of weekly ingredient variations appeared most effective during the starter and grower phases, but was less significant during the sixth week.

Burn injury in epileptic patients: an experience in a tertiary institute

The objective of this study was to evaluate the incidence, types and severity of burn injuries, including sites involved, morbidities, operative procedures, and their outcomes, to prevent or reduce the frequency and morbidity of such injuries in epileptic patients. This retrospective study was conducted at our centre between February 2008 and January 2012. The study included 54 patients who sustained burn injuries due to epileptic seizures, accounting for 1.3% of all burn admissions. All patients, irrespective of the severity of their injuries, were admitted to our centre, assessed, treated and educated regarding specific preventive measures. All study data were evaluated from patient medical records. Causes of burn injury were as follows: scald burns (30), contact with hot surfaces (12), electrical burns in the bathroom (6), and flame burns (6). Second degree burns were the most common (18 out of 54 patients) and third degree burns were the least common. Upper limb and trunk were the most common sites involved (36 out of 54 patients). Thirty patients required surgical intervention whereas the remainder was conservatively managed. Most of the injuries occurred in the age group between 30-37 years. Injuries occurred predominantly in females [42 females, 12 males; F:M=3.5:1]. The study revealed that patients with epilepsy should be categorized as a high risk group considering the sudden and unpredictable attack of epileptic seizures leading to loss of consciousness and accidental burn injuries. Early surgical intervention and targeting of all epileptic patients for education and instituting the specific preventive measures gives good outcomes.

Actinomycetoma leg ulcers in north India

INTRODUCTION

Actinomycetoma is a chronic subcutaneous infection caused by aerobic branching actinomycetes. Its clinical features are firm tumefaction of the affected site and the presence of abscesses, nodules, and sinuses that drain a seropurulent exudate containing filamenting granules. Cutaneous actinomycetoma has traditionally been deemed uncommon in the northern part of India, but recent studies have refuted this long-held notion. Thus, clinicians have to be more vigilant when they come across patients with long-standing cutaneous lesions with typical mycetomic features, as early diagnosis and treatment hold the key to a cure.

MATERIALS AND METHODS

This prospective study was carried out from June 2009 to December 2012 and comprises 13 cases of chronic nonhealing ulcers of the lower limb subsequently diagnosed as mycetoma. Socioetiological aspects, prevalence, early diagnosis, and treatment modalities of this condition are described in the study along with a simple, yet inclusive, scoring system to evaluate the post-treatment results.

RESULTS

Ten out of 13 cases with clinical suspicion of actinomycetoma were diagnosed with the condition. A majority of these diagnosed patients were middle aged and belonged to lower socioeconomic status. There was no sexual preponderance. Early treatment in the form of modified Welsh regime (amikacin + cotrimoxazole + rifampicin) was started and showed acceptable results. Post-treatment outcomes were measured on the basis of a new scoring system (Masoodi's score) devised by the authors. Two patients had a score of > 7 (good), 5 patients had a score of 4-6 (fair), and 3 patients had a score of ≤ 3 (poor).

CONCLUSION

Correct identification of the infective aetiological agent is imperative to direct therapy against actinomycetoma. Treatment success depends on an early diagnosis and instigation of treatment. Efficacy of chemotherapy, if started after an early diagnosis in the form of modified Welsh regime, produces acceptable results in the form of clinical and physical remission or cure. The functional and cosmetic parameters do not respond as well to treatment and the authors propose a new scoring system which takes into account the post-treatment results in totality.

Management of post road traffic accident compound leg defects using fasciocutaneous flaps

OBJECTIVE

To highlight the role of fasciocutaneous flaps in the management of leg and foot defects sustained after trauma, in rural India.

METHOD

This was a prospective study conducted on patients with traumatic defects of the leg and foot, admitted between May 2001 and April 2007. Selection of flaps was done on the basis of defect size, site and condition of surrounding tissue. Ipsilateral flaps (proximally- and distally-based), contralateral-leg flaps and free flaps (anterolateral thigh and radial forearm) were raised according to standard techniques and wounds resurfaced accordingly. The outcome was considered 'excellent' when there was no flap necrosis and no donor site morbidity, 'good' when there was some infection, either at the donor or recipient site, but no necrosis, 'satisfactory' when partial flap necrosis and 'poor' when there was flap loss.

RESULTS

One-hundred and ten patients (86 males and 24 females) with post-traumatic leg defects underwent reconstruction with different fasciocutaneous flaps. The ages of the patients ranged from 6 years to 58 years, with a mean age of 28.2 +/- 11.5 years. Forty cases (37%) underwent immediate reconstruction within the first 72 hours and in 70 cases (63%) delayed reconstruction was done. Hospital stay of the patients ranged from 8 days to 54 days, with a mean of 20.2 +/- 1.9 days. There were no complications recorded at donor site. The overall results were considered excellent in 92 cases (84%), good in 12 (11%), satisfactory in four (3.6%) and poor in two cases (1.8%), where flap necrosis occurred.

CONCLUSION

Our results suggest fasciocutaneous flaps are convenient, simple, reliable and easy to manage. The majority of compound leg defects can be reconstructed with fasciocutaneous flaps either from the ipsilateral leg, contralateral leg or in the form of free flaps.

Motorcycle Muffler–Induced “Pillion Burns” of Distal Leg

Motorcycles have emerged as a viable mode of transport for millions in the third world. Mufflers (exhaust pipes in some countries) remain a potential “Achilles’ tendon” or a designing flaw in the mass-produced, economical motorcycles of the developing world. Owing to the excessive temperature they attain while the hot exhaust gases pass through them and their proximity to the lower limbs while riding a motorcycle, they can lead to burns of varying nature in the lower leg. This is a descriptive retrospective study of muffler-induced lower leg burns treated at our hospital from January 2008 to December 2012. Various parameters including history, exact mode of injury, age, sex, degree and location of burn, treatment modalities, and other relevant circumstantial/logistical factors associated with such injuries were noted; data were tabulated and statistically arranged to gain an insight into this problem. Possible interventions that may help avoid such injuries are also briefly mentioned. Certain findings that are quite distinct to the findings of a few earlier studies carried out on this topic (in the developed world) remain the highlight of our study. The typical muffler-induced burns in the Indian setting occur almost exclusively in the male pillions, most of the times in the right leg in an area near the medial maleolus, and are usually second degree and respond to conservative management. Prompt treatment can circumvent much of the dreaded complications. Preemptive efforts in designing of motorcycles and following traffic regulations at the individual level remain the key to prevention.

Angiographic Estimation of Culprit Vessel Disease Severity in Acute ST- Segment Elevation Myocardial Infarction after Thrombolysis

Introduction: To study the angiographic disease severity of the infarct vessel after thrombolysis in patients with acute ST-elevation myocardial infarction and their 90 days outcome.  Methods: We conducted a retrospective analysis of a prospectively maintained cardiology database at Shifa International Hospital from February 2011 to August 2011. A total of 57 patients who underwent thrombolysis for acute ST elevated Myocardial Infarction and subsequent coronary angiographies within 24 hours of hospitalization were studied. Angiographic disease severity in the infarct vessel was quantified as mild (<50%), moderate (50-70%), severe (70-99%) and total occlusion (100%). Secondary outcomes of recurrent ischemia/reinfarction, target lesion revascularization and death were also assessed at three months follow up.  Results: Thrombolysis was successful in 48 patients. All nine cases of failed thrombolysis underwent rescue PCI. Mean time of catheterization from thrombolysis was 16 ±4 hours. Total 56 (98.2%) patients had severe (>70%) and 1 patient had moderate (50-70%) angiographic disease of the infarct vessel. Left anterior descending artery was the infarct vessel in 32 (56%) cases and right coronary artery in 20 (35%). Total 15 (26%) patients had double vessel and 11 (19%) had triple vessel coronary artery disease. Percutaneous coronary intervention was performed in all patients using bare metal stents or drug eluting stents. At three month follow-up, only one patient had recurrent myocardial infarction due to stent thrombosis.  Conclusions: The overwhelming majority of patients presenting with ST elevation myocardial infarction have angiographic evidence of severe underlying disease in the infarct vessel despite clinically successful hrombolysis. Keywords: acute coronary syndrome; coronary angiography; myocardial infarction; thrombolysis.

Elective laparoscopic cholecystectomy for surgical trainees: predictive factors of operative time

AIM

To determine pre-operative criteria to predict duration and technical difficulty of laparoscopic cholecystectomies that will aid in identifying patients suitable for training lists.

METHOD

A prospective analysis of 835 consecutive patients who underwent laparoscopic cholecystectomies. Data collected included patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (ES), duration of surgery (from skin incision to skin closure), peri-operative and postoperative complications and histological gallbladder wall thickness.

RESULTS

Post-operative complications were seen in 3% (n=20). Overall open conversion rate was 2%. The mean duration of surgery was 78.76 +/- 1.75 minutes. Age, ERCP and ES were not independent predictors of a long operation time. However, a positive correlation was seen with histological gallbladder wall thickness and duration of surgery (p=0.001). The mean operating time for gallbladder wall thickness < 3 mm was 72.1 +/- 1.62 minutes whereas that for > 3 mm thickness was 83.3 +/- 2.05 minutes (p=<0.001).

CONCLUSION

Gallbladder wall thickness can be used as an independent predictor of a long operation time.

Use of tissue ink to maintain identification of individual cores on needle biopsies of the prostate

BACKGROUND

There is an increasing necessity to extract the maximum amount of information, beyond even a cancer diagnosis, from prostate biopsies. Thus, maintaining site-specific information regarding individual biopsy cores might be critical.

AIM

To evaluate the applicability of employing tissue ink to maintain the identity of individual prostatic biopsy cores.

METHOD

In this ongoing study, 12 core prostate biopsy specimens are sent to the laboratory in individual pots labelled according to anatomical site. The specimens are placed in two separate multi-compartment cassettes. They are inked with different colours to identify the site of origin from each lobe. The cassettes are then processed with a single paraffin block for each side; the six cores from each side can be mounted on a single slide.

RESULTS

The different colours used adhere well to the biopsy cores, thus maintaining the identity of each core. Six cores from each side are embedded in a single paraffin block and examined on a single slide, making it cost-effective, while maintaining high quality, accurate histopathological information.

CONCLUSION

Differential inking of prostate biopsy cores is an easily applicable method that is cost-effective and provides tumour location information. Prostate biopsy data archived to maintain individual core information might be used to determine applicability of such information to predict extra-capsular extension by correlating with imaging and radical prostatectomy findings, and for treatment planning.

Multiple sclerosis in Pakistan

We describe retrospective data from the largest series of patients (n=142) with multiple sclerosis (MS) from Pakistan. Mean age at onset was 27 years, with a female to male ratio of 1.45:1. The disease onset was polysymptomatic in 75% patients. Motor weakness was the most common onset symptom (70%), followed by sensory symptoms (45%). Optico-spinal type of MS was seen in only 3% of patients The courzse was relapsing-remitting (RR) in 81%, primary progressive (PP) in 21%, and secondary progressive (SP) in 4% of patients. Almost three-fourths of the patients were moderately (45%) or severely (31%) disabled at the time of evaluation. Two-thirds of patients with severe disability had a mean disease duration of only 5.2 years. In conclusion, MS is not uncommon in Pakistan, and many patients were found to have severe disability despite short disease duration. Multiple Sclerosis 2007; 13: 668-669. http://msj.sagepub.com

Complications of Renal Transplantation in Patients With Amyloidosis

OBJECTIVE

Renal transplantation in patients with end-stage renal failure (ESRF) secondary to amyloidosis carries a high risk of postoperative complications. Preoperative investigations are crucial for a successful perioperative course. There are limited data studying the outcome of patients with amyloid nephropathy who undergo renal transplantation. Therefore, we undertook this retrospective review of our experience to highlight the difficulties.

MATERIALS AND METHODS

Thirteen patients with AA amyloid-induced ESRF underwent cadaveric renal transplantation from 1985 to 2001 in the Irish transplant population. The perioperative course of these patients was compared to an age-matched control group of 142 nonamyloid patients who had cadaveric renal transplantation during the same time period. Both groups were followed annually for 5 years.

RESULTS

The 1- and 5-year patient survival rates were 69% and 69% in the amyloid as compared with 97% and 87% for the control group. In the amyloid group, early death was primarily due to cardiac causes followed by complications of sepsis. Graft survival at 1 and 5 years was 56% and 56% in the amyloid group as compared with 87% and 59% in the control group (P = .0027). Four deaths with a functioning graft contributed to the early graft losses.

CONCLUSION

Increased complications, especially cardiac, are noted post-renal transplantation among patients with renal amyloidosis. However, appropriate guideline, for the perioperative management of these patients has yet to be established.

Desmocollin switching in colorectal cancer

The desmocollins are members of the desmosomal cadherin family of cell-cell adhesion molecules. They are essential constituents of desmosomes, intercellular junctions that play a critical role in the maintenance of tissue integrity in epithelia and cardiac muscle. In humans, three desmocollins (Dsc1, Dsc2 and Dsc3) have been described. The desmocollins exhibit tissue-specific patterns of expression; only Dsc2 is expressed in normal colonic epithelium. We have found switching between desmocollins in sporadic colorectal adenocarcinoma with a reduction in Dsc2 protein (in 8/16 samples analysed by immunohistochemistry) being accompanied by de novo expression of Dsc1 (16/16) and Dsc3 (7/16). Similar results were obtained by western blotting of a further 16 samples. No change was found in Dsc2 mRNA, but de novo expression of Dscs 1 and 3 was accompanied by increased message levels. Loss of Dsc2 (8/19) and de novo expression of Dsc1 (11/19) and Dsc3 (6/19) was also found in colorectal adenocarcinomas on a background of colitis. The data raise the possibility that switching of desmocollins could play an important role in the development of colorectal cancer.

Metformin monotherapy in lean women with polycystic ovary syndrome

This study was carried out to compare ovulation and pregnancy rates in response to metformin therapy in lean and obese women with polycystic ovary syndrome (PCOS). A total of 34 (17 lean and 17 obese) women with PCOS were treated with 500 mg metformin 3 times daily for 12 weeks. In the lean and obese groups, the mean body mass index was 24 and 36, and the mean fasting insulin concentrations were 12 and 21 mIU/l respectively. There was no difference between the two groups as regarding age, DHEA-S, androstenedione, 17-OH progesterone and LH concentrations. In the lean and obese groups 15/17 women (88%) and 5/17 women (29%) ovulated while 11/17 women (65%) and 3/17 women (18%) conceived respectively. Comparison between the groups was found to be statistically significant. Metformin monotherapy is very effective in improving ovulation and pregnancy rates in lean women with PCOS as compared with obese women.

Vasography in urethral stricture: novel application of an old technique

Urethral stricture disease in men has traditionally been investigated with ascending and voiding cystourethrography as well as urethroscopy. The main emphasis during the preoperative assessment is on establishing the exact extent of the disease process in order to plan appropriate management. We describe a technique that represents a novel approach to the assessment of proximal urethral stricture and in selected cases would be of immense help in defining its precise nature and planning definitive treatment.

DICLOFENAC SUPPOSITORY ANALGESIA FOR TRANSRECTAL ULTRASOUND GUIDED BIOPSIES OF THE PROSTATE: A DOUBLE-BLIND, RANDOMIZED CONTROLLED TRIAL

PURPOSE

A significant proportion of men undergoing transrectal ultrasound (TRUS) and prostate biopsy report pain during the procedure. A number of different methods of pain relief have been suggested in the literature. We prospectively evaluated the effect of diclofenac suppositories on pain experienced by men undergoing TRUS and prostate biopsy.

MATERIALS AND METHODS

A prospective, randomized, double-blind, placebo controlled study was performed in 72 patients requiring prostate biopsy. Patients were randomly assigned to receive 100 mg diclofenac or placebo 1 hour prior to the procedure. They were asked to indicate on a 10 cm visual analogue scale the degree of discomfort during the procedure. The patients were then seen 2 weeks later and any morbidity, including infection and bleeding, was assessed.

RESULTS

Patients given diclofenac had significantly lower pain scores than those given placebo (2.8 vs 4.9, p <0.001). The 2 groups were similar in regard to age, prostate volume, biopsy number, prostate specific antigen, histological diagnosis and complication rate.

CONCLUSIONS

Rectal administration of diclofenac 1 hour prior to TRUS and prostate biopsy is a simple procedure that significantly relieves the pain experienced with no increase in morbidity. With the trend toward more core samples, screening for prostate cancer and the younger age of patients undergoing biopsy we urge urologists to provide analgesia for this painful procedure.

Delayed cholangitis resulting from a retained T-tube fragment encased within a stone: a rare complication

Inserting a T-tube after choledochotomy for the removal of bile duct stones remains a time-honored practice. Biliary drainage after bile duct exploration has some advantages. It minimizes bile leakage, provides access for cholangiography, and removes occasional retained stones. The use of T-tubes also has been associated with significant complications. Biliary sepsis, bile duct trauma during removal, bile leakage leading to peritonitis, retention of a fragment, stricture formation after removal have been reported. We report an unusual case of cholangitis caused by a T-tube fragment within a large stone, occurring 11 years after bile duct exploration. A 39-year-old woman underwent common bile duct exploration with insertion of a T-tube. Cholangiography was normal, but as the T-tube was removed, its horizontal limb was missing. The patient failed to present for endoscopic removal a few weeks after surgery Five years later, she presented with recurrent biliary pains and a mild episode of cholangitis. This last episode was associated with severe pain and jaundice. After initial conservative treatment, endoscopic retrograde cholangiopancreatography was performed, and endoscopic removal of the fragment and stone material was successful. Despite the declining numbers of bile duct explorations in the laparoscopic era and the tendency to use transcystic drainage or primary closure of a choledochotomy, the T-tube will continue to be a useful tool in biliary surgery, subject to consideration of the indications and the available alternatives. The reported case highlights the importance of careful tube preparation to prevent partial separation at removal, and early removal of a missing fragment to avoid potential serious complications.

Incidence of Helicobacter pylori in patients with interstitial cystitis

OBJECTIVE

Chronic gastritis has compelling similarities to interstitial cystitis (IC). It is characterised by chronic pain in a tubular organ. Histologically, epithelial damage, inflammatory response in the lamina propria and epithelial ulcerations are seen. An infective cause was rarely considered until the emergence of Helicobacter pylori over the past 15 years. We have had experience of patients with bladder pain and irritability reporting improvement with antihistamines. It has also been reported that IC symptoms improved dramatically after treatment for H. pylori infection. Previous studies have determined the incidence of H. pylori antibodies in women with IC but we examined bladder material histologically and performed the Campylobacter-like organism (CLO) test on the biopsy specimens.

MATERIALS AND METHODS

A prospective controlled study was performed. Patients with urinary symptoms fulfilling the National Institute of Diabetes and Digestive and Kidney Diseases criteria for IC underwent GA cystoscopy at which the macroscopic appearance of the bladder was noted and biopsies were taken. The biopsy material underwent histological examination and CLO test. Control patients who were undergoing cystoscopy for reasons other than investigation of IC also had biopsy taken and the CLO test was performed on these specimens.

RESULTS

Five of 15 patients with symptoms and signs of IC had a positive CLO test. Three of 15 patients of the control group had a positive CLO test. With the 2-sided chi(2) test there was no statistical difference between the 2 groups.

CONCLUSION

Our small prospective control study does not support the hypothesis that H. pylori is an important component in the pathogenesis of interstitial cystitis.
