On the Role of Ultrasonography and CT Scan in the Diagnosis of Acute Appendicitis

The purposes of this study were to revisit the utility of ultrasonography (USG) as a primary imaging modality in acute appendicitis (AA) and to establish the role of CT scan as a second-line/problem-solving modality. All cases of suspected AA were referred for urgent USG. USG was done with standard protocol for appendicitis. Limited computed tomographic (CT) scan [NCCT ± CECT (IV contrast only)] was done for the lower abdomen and pelvis where sonographic findings were equivocal. One hundred and twenty-one patients were referred for USG for suspected appendicitis. Eight-four patients underwent surgery for AA based on clinical as well as imaging findings, of whom 76 had appendicitis confirmed at histopathology. Three patients were misdiagnosed (3.6 %) on USG as appendicitis. Of 76 patients of appendicitis confirmed histopathologically, 63 (82.8 %) had features of appendicitis on USG and did not require any additional imaging modality. Of 121 patients, 12 (10 %) needed CT scan because of atypical features on USG. Of these 12 patients, seven had retrocecal appendicitis, and three high-up paracolic appendicitis. USG alone had sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 81, 88, 92.6, 71.6, and 83 %, respectively. When combined with CT scan in select cases, the sensitivity, specificity, PPV, NPV, and accuracy of combined USG + CT scan were 96 % (P?=?0.0014), 89 %, 93 %, 93.5 % (P?=?0.0001), and 93 % (P?=?0.0484), respectively. Twenty-eight (23 %) patients were given alternative diagnosis on USG. Dedicated appendiceal USG should be used as a primary imaging modality in diagnosing or excluding AA. Appendiceal CT can serve as a problem-solving modality.     

Thoracic cord herniation and associated intra-operative nuances: a report

Background

Thoracic cord herniation is a well-established entity in the literature. Majority of the published literature deals with its surgical management in terms of “mere” detethering of cord. However, not much is written about the degree of herniation and ectopic cord tissue and its management.

Case summary

A 58-year-old male presented to us with progressive difficulty in walking. Imaging revealed a cord herniation at T7–8 level. Surgical detethering was planned. However, a significant amount of “ectopic” cord tissue was found outside the dural defect intra-operatively. Simple detethering and repositioning was difficult. Hence, the ectopic tissue was excised under neuro-physiologic monitoring and no major change was recorded intra-operatively/post-operatively.

Conclusions

Thoracic cord herniation surgery may be more than simple detethering and cord repositioning. If encountered in similar situations intra-operatively, surgeons should be able to excise ectopic tissue without grave post-operative deficits. Neuronal plasticity probably plays an important role in the pathophysiology of long-standing cord herniation.

     

Improving Trauma Care in India: the Potential Role of the Rural Trauma Team Development Course (RTTDC)

The Rural Trauma Team Development Course (RTTDC) was devised to optimize trauma resuscitation training in under-resourced rural institutions. This program appears ideal for India because of its dense traffic, large population, and high frequency of rural trauma. We report on the feasibility and desirability of introducing RTTDC in India. An instructor course for 20 faculties and a provider course for 23 were conducted in New Delhi, India. The courses were evaluated by multiple choice question (MCQ) performance, by rating the modules on a three-point scale (1 = very relevant, 2 = relevant, and 3 = not relevant) for communication skills, principles of performance improvement and patient safety (PIPS), and clinical scenarios. Evaluation questionnaires including desirability of promulgation in India were completed using a five-point Likert Scale (1 = strongly agree, 2 = agree, 3 = neutral, 4 = disagree, and 5 = strongly disagree). Overall written comments were also provided. Both faculty and providers improved post-course MCQ scores (p?<?0.05) with lower scores in the provider group. Seventy-eight percent faculty and 74 % providers rated the communication module very relevant. PIPS was rated very relevant by 72 % faculty and 65 % providers. There were over 150 comments, generally positive with over 90 % of both faculty and providers rating strongly agree to agree that the course be promulgated widely in India. The RTTDC including plans for promulgation was enthusiastically received in India, and its potential for improving trauma care including communication skills and PIPS appears excellent.     

Study of Surgical Emergencies of Tubercular Abdomen in Developing Countries

To study the various modes of presentation, diagnosis, and management of surgical emergencies of tubercular abdomen. This prospective study of surgical emergencies of tubercular abdomen was conducted in 50 patients who attended our surgical emergency from 2006 to 2008. Patients were evaluated thoroughly with history, physical examination, routine investigations, and special investigations such as ELISA, PCR, barium studies of gastrointestinal tract, and diagnostic laparoscopy as required and managed with medical and surgical treatment as necessary. The most of patients were from rural areas, in the third to sixth decades with slight male preponderance. Abdominal pain, vomiting, and constipation were commonest presenting symptoms. About 20 % patients had history of pulmonary tuberculosis and 16 % patients presented with ascites. PCR for blood and ascitic fluid was positive in 72 and 87.5 % patients, respectively. About 24 % patients were managed nonoperatively and responded to ATT. About 76 % patients needed surgery among which one-fifth of patients were operated in emergency. Procedures like adhesiolysis of gut (47.3 %), strictureplasty (10.5 %), resection anastomosis (5.2 %), right hemicolectomy (5.2 %), and ileotransverse anastomosis (7.8 %) were performed in 30 patients and peritoneal biopsy and lymph node biopsy in the remaining 8 patients. Both medically and surgically managed patients were put on antitubercular therapy. Abdominal tuberculosis is a disease of middle-aged rural people, presenting commonly with abdominal pain and vomiting with right lower abdominal tenderness. PCR (blood and ascites) for tuberculosis is much more sensitive than IgM ELISA (blood and ascites). The most of patients required surgical procedures and all patients responded dramatically to antitubercular therapy symptomatically with increase in the hemoglobin level and decrease in ESR.     

Pedicle streaking: A novel and simple aid in pedicle positioning in free tissue transfer

Introduction:The pedicle positioning in free tissue transfer is critical to its success. Long thin pedicles are especially prone to this complication where even a slight twist in the perforator can result in flap loss. Pedicles passing through the long tunnels are similarly at risk. Streaking the pedicle with methylene blue is a simple and safe method which increases the safety of free tissue transfer.Conclusion:This simple and novel method is very reliable for pedicle positioning avoiding any twist necessary for successful free tissue transfer.KEY WORDS: Free flaps, pedicle, perforator     

Simple device to determine the pressure applied by pressure clips for the treatment of earlobe keloids

Background:Keloids of the ear are common problems. Various treatment modalities are available for the treatment of ear keloids. Surgical excision with intralesional steroid injection along with compression therapy has the least recurrence rate. Various types of devices are available for pressure therapy. Pressure applied by these devices is uncontrolled and is associated with the risk of pressure necrosis. We describe here a simple and easy to use device to measure pressure applied by these clips for better outcome.Objectives:To devise a simple method to measure the pressure applied by various pressure clips used in ear keloid pressure therapy.Results:The pressure applied by different clips was variable. The spring clips were adjustable by slight variation in the design whereas the pressure applied by binder clips and magnet discs was not adjustable.Conclusion:The uncontrolled/suboptimal pressure applied by certain pressure clips can be monitored to provide optimal pressure therapy in ear keloid for better outcome.KEY WORDS: Clips, device, earlobe, magnetic discs, measure, pressure therapy, splint     

Solitary sacral osteochondroma without neurological symptoms: a case report and review of the literature

Purpose

To report a case of solitary sacral osteochondroma without neurological symptoms and describe the en bloc excision of the tumour, as well as review the literature on osteochondroma involving the sacrum.

Methods

Summary of the background data: although osteochondromas are among the most common benign tumours of the bone, they uncommonly involve the spine. Its occurence in the sacrum is rare, accounting for only 0.5 % of the osteochondromas involving spine. All previous cases of sacral osteochondroma have reported neurological symptoms on presentation.

Case report

A 21-year-old male presented with a palpable, painless mass in the left side of the sacral region of 1 year duration, without neurological symptoms. Radiological studies showed a well-circumscribed lesion with bony osteoid within arising from the sacrum at S3–S4 level left to midline, with features suggestive of osteochondroma. The tumour was excised en bloc through posterior approach. A literature review of sacral osteochondroma was conducted using MEDLINE search of English Literature and bibliographies.

Results

Histopathological studies showed the lesion to consist mature bone trabeculae with active enchondral ossification with cap of normal hyaline cartilage. Literature review yielded only 8 cases of sacral osteochondroma reported earlier.

Conclusion

This is the 9th case of solitary osteochondroma of the sacrum to be reported, the first to be reported without any neurological symptoms, and third case reported for which en bloc excision was performed.

     

Snake bite induced cellulitis leading to infected open dislocation of the first metacarpophalangeal joint – A rare complication

Non-traumatic open dislocation of the first metacarpophalangeal joint is a rare phenomenon. We present a rare such occurrence secondary to snake bite induced cellulitis. A 22-year-old girl presented with pain and instability of her right thumb two months. She had snake bite two months back following which she developed cellulitis which gradually became infected. She presented with raw area over her dorsal aspect of the thumb with active infection. Radiographs revealed metacarpophalangeal joint dislocation. She underwent debridement, stabilisation and soft tissue coverage. At final follow up, she was pain free and the wound healed completely.     

Non-union of calcaneum – A rare complication of calcaneal fracture – A case report with brief review of literature

Intra-articular fractures of calcaneum are known to be difficult to manage and lead to multiple complications including subtalar arthritis and malunion. However, non-union of calcaneum is rarely encountered. Only a total of six studies reporting on 12 patients could be found on reviewing the available literature (English language only). One such case of non-union of calcaneal fracture and its successful management is being reported in this case report. In addition, extremely limited literature available on calcaneal non-union is also briefly reviewed. Role of subtalar arthrodesis with internal fixation of fracture and bone grafting for successful management of this rare complication is highlighted along with the possibility of under-reporting of this relatively unknown complication.
