Ileocaecal intussusception is a common cause of acute intestinal obstruction presenting as a surgical emergency. We report a case of amoebic colitis in a 62 years old man complaining of acute colicky pain in the right iliac fossa, associated with a three-day history of constipation but no other gastrointestinal tract symptoms. There was rebound tenderness on palpation of the right iliac fossa. Ultrasound scans revealed free fluid and a loop within a loop image in this area. At laparotomy, we discovered an Ileocaecal intussusception associated with a gangrenous caecum. A right hemicolectomy was performed with satisfactory outcome. The final diagnosis of amoebic colitis was obtained post-operatively using serology and pathology. This rare aetiology must be considered in patients with acute pain in the right iliac fossa in the tropical regions. Tropical surgeons must be aware of this scenario before they label a case of intussusception as idiopathic. The identification and treatment of invasive amoebic infection may reduce the recurrence of idiopathic intussusception.

Fusobacterium nucleatum is a gram-negative bacteria associated with diverse infections like appendicitis and colorectal cancer. It mainly attacks the epithelial cells in the oral cavity and throat of the infected individual. It has a single circular genome of 2.7 Mb. Many proteins in F. nucleatum genome are listed as “Uncharacterized.” Annotation of these proteins is crucial for obtaining new facts about the pathogen and deciphering the gene regulation, functions, and pathways along with discovery of novel target proteins. In the light of new genomic information, an armoury of bioinformatic tools were used for predicting the physicochemical parameters, domain and motif search, pattern search, and localization of the uncharacterized proteins. The programs such as receiver operating characteristics determine the efficacy of the databases that have been employed for prediction of different parameters at 83.6%. Functions were successfully assigned to 46 uncharacterized proteins which included enzymes, transporter proteins, membrane proteins, binding proteins, etc. Apart from the function prediction, the proteins were also subjected to string analysis to reveal the interacting partners. The annotated proteins were also put through homology-based structure prediction and modeling using Swiss PDB and Phyre2 servers. Two probable virulent factors were also identified which could be investigated further for potential drug-related studies. The assigning of functions to uncharacterized proteins has shown that some of these proteins are important for cell survival inside the host and can act as effective drug targets.

Carcinomas arising from an exstrophic urinary bladder are rare entities, and only seven such cases have been reported in the literature. We present the eighth case of advanced squamous cell carcinoma arising from an exstrophic bladder, with a pertinent review of the literature. The mean age of the patients was 54.9 years, with a male to female ratio of 3:1. The average duration of symptoms was 18.6 months. The appearance of a new growth was the most common symptom. Three patients had stage I disease, one patient each had stage II and III disease, two patients had stage IV disease, and the disease stage was not known in one patient. Five out of these eight patients underwent surgery. Four patients in the treatment group remained disease-free, with a mean survival period of 30 months. In conclusion, regular surveillance with cystoscopy is advised in all cases that had primary closure of the exstrophic bladder.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To compare the clinical and radiological outcomes of modified mini-open transforaminal lumbar interbody fusion (modMOTLIF) and open TLIF (OTLIF). OVERVIEW OF LITERATURE: Minimally invasive transforaminal lumbar interbody fusion (MTLIF) is associated with less blood loss, shorter hospital stay, and less pain. However, it has concerns like increased radiation exposure, steep learning curve, and instrumentation cost. We modified the MTLIF technique by direct freehand insertion of pedicle screws using stab incisions without tubular retractors. METHODS: The study included 24 patients in the modMOTLIF group and 27 patients in the OTLIF group. The average follow-up period was 25.6 months. Clinical outcomes were measured using Visual Analog Scale (VAS) and Oswestry Disability Index (ODI) scores. Serial X-rays were acquired at 1, 3, 6, 12, and 24 months to assess the union and presence of instability. We also compared blood loss and length of hospital stay in both groups. RESULTS: All patients showed progressive improvement in VAS and ODI scores. No differences were observed in the preoperative and postoperative ODI and VAS leg scores between the groups. The immediate postoperative VAS back score was significantly higher in the OTLIF group than in the modMOTLIF group; however, no difference was observed at 1 and 2 years. Radiological analysis showed nonunion in one and two patients in the OTLIF and modMOTLIF groups, respectively. The average blood loss was 63 mL in the mod-MOTLIF group and 254 mL in the OTLIF group. The mean hospital stay was 3 days for the modMOTLIF group and 5 days for the OTLIF group. CONCLUSIONS: modMOTLIF was associated with reduced blood loss and shorter hospital stay compared with OTLIF. No significant differences were observed in the clinical and radiological outcomes between the groups after 2 years despite reduced back pain in the immediate postoperative period in patients who underwent modMOTLIF.

Developmental anomalies of the axis are commonly encountered, especially anomalies involving the odontoid process. Anomalies of the posterior elements are uncommon. We describe a unique case of agenesis of posterior elements of C2 with basilar invagination and atlanto-axial dislocation. An obese 8-year-old boy presented with symptoms of cervical myelopathy. Radiological workup revealed a craniovertebral junction anomaly with occipitalised atlas, absent posterior elements of axis, and hypertrophied C3 spinous process. Atlanto-axial instability and basilar invagination was present. Magnetic resonance angiography revealed hypoplastic left vertebral artery. Traction with cervical tongs failed to improve the alignment and symptoms. Anterior trans-oral release, followed by posterior decompression and custom-made instrumentation, was done. The patient recovered completely and was asymptomatic at the end of two years. X-ray and computed tomography scan demonstrated reduction of basilar invagination and maintenance of alignment. This is the first case to be reported of agenesis of posterior elements of axis associated with basilar invagination. One should look for this condition in patients with hypertrophied spinous process of C3. Utilization of hypoplastic pedicle of axis serves as an additional fixation point to increase the stability of the construct.

STUDY DESIGN: Retrospective case series. PURPOSE: To describe a novel single incision that combines anterior and posterior approaches for decompression and instrumented fusion to treat tuberculosis of the thoracic spine and study the neurological and radiological outcomes. OVERVIEW OF LITERATURE: Tuberculosis of the spine remains a major health issue in many developing countries. The options for treating tuberculosis of the thoracic spine include the anterior, posterior, and combined approaches, each with its advantages and disadvantages. METHODS: Totally, 143 patients with tuberculosis of the thoracic spine were surgically treated using the “Versatile approach”. Posterior fixation was performed using sublaminar wires and a Hartshill rectangle in all patients. Anterior reconstruction was accomplished using bone graft harvested from autologous rib, iliac crest, or fibula. RESULTS: The study included 45 males and 98 females, with a mean age of 33.18±18.65 years (range, 3–82 years) and a mean follow-up of 60.23±24.56 months (range, 18–156 months). Kyphosis improved from a mean value of 24.02 preoperatively to 10.25 postoperatively. A preoperative neurological deficit was observed in 131 patients, with 130 patients regaining ambulatory power. No patient had deterioration of neurological status following surgery. Fusion was achieved in all cases. The visual analogscale score improved from an average score of 7.02 preoperatively to 1.51 at final follow-up. Eight patients had superficial macerations, which healed spontaneously. One patient had buckling of the anterior graft, and one patient had implant breakage following road traffic accident. CONCLUSIONS: The “Versatile approach” is an effective, single-stage, single-incision method that combines anterior and posterior approaches for the surgically treating tuberculosis of the thoracic spine. It offers the advantage of direct visualization for decompression and reconstruction of the anterior and posterior vertebral columns, thus providing an excellent, long-lasting clinical outcome.

INTRODUCTIONNo single study has established the superiority of one treatment of Kienböck's disease over the other. Pooled outcome data is presently considered the best way to add to the knowledge and understanding of Kienböck's disease.

METHODSA total of 12 patients (9 male and 3 female) with Kienböck's disease were included in the present case series. The mean age of the 12 patients was 28 years. One patient presented in Lichtman stage I, five in Lichtman stage II, five in Lichtman stage IIIa, and one in Lichtman stage IV. Univariate and multivariate analyses of the obtained data were performed to identify any correlations.

RESULTSThe mean follow-up time was 62 months, and the mean modified Mayo wrist score improved from the preoperative value of 29.5 to the final value of 89.6. Lichtman stage at presentation showed moderate positive correlation with the duration of symptoms (r = 0.56), and a strong negative correlation with the preoperative and final modified Mayo scores (r = -0.89 and r = -0.77, respectively). The final modified Mayo score showed moderate negative correlation with the duration of the symptoms (r = -0.55). There was a significant difference in the preoperative modified Mayo scores of patients who presented in stage II and those of patients who presented in stage IIIa (p = 0.03). However, the difference in the final modified Mayo scores of the patients in these stages was not significant (p = 0.14).

CONCLUSIONLichtman's stage is moderately related to the duration of symptoms, suggesting natural progression of the disease. The final outcomes of stages II and IIIa were the same irrespective of the surgical treatment (radial shortening and/or vascularised bone grafting).

STUDY DESIGN: Retrospective case series. PURPOSE: Describe the technique and evaluate the outcome of apical vertebral column resection (VCR) with sagittal rotation and anterior opening and posterior closing (AOPC) maneuver for correction of severe post-tubercular kyphosis (PTK). OVERVIEW OF LITERATURE: The surgical procedures described for the correction of PTK are VCR, pedicle subtraction osteotomy, transpedicular decancellation osteotomy, and closing-opening osteotomy. METHODS: We retrospectively evaluated 21 patients who had been operated on with single stage apical VCR with AOPC maneuver. Radiographs were obtained before surgery and at regular follow-up intervals. These were used to calculate the angle of kyphosis. Back pain was rated using the Visual Analog Scale (VAS) and neurological status was graded using Frankel grading. Radiological outcome was assessed by the improvement in the angle of kyphosis and fusion following surgery. Neurological status was assessed using Frankel grading. RESULTS: The study included eight males and 13 females with a mean age of 21.9 and average follow-up time of 30.4 months. The average number of vertebral bodies destroyed was 2.57. Kyphosis was improved from a mean of 68.42°±13.23° preoperative to 8.71°±4.58° postoperative. The average correction achieved was 87.10%. Preoperative VAS score improved from a mean of 6.38±0.92 preoperative to 1.38±0.49 postoperative. No patients had any sign of neurological deterioration. Seven out of eight patients with a preoperative neurological deficit improved following surgery. Two patients developed superficial wound maceration, one had persistent postoperative hypotension, and the other developed hemothorax. All patients recovered fully without a need for additional surgery. CONCLUSIONS: Single stage simultaneous anterior column lengthening and posterior column shortening is an effective method for surgical correction of severe PTK.

PURPOSE: The aim of this study was to evaluate safety and therapeutic efficacy of lutetium 177 prostate-specific membrane antigen (Lu-177-PSMA) in metastatic castration-resistant prostate cancer (mCRPC) patients with low performance status.METHODS: Twenty-two patients already treated with anti-androgens and docetaxel were enrolled for one cycle of Lu-177-PSMA therapy. Haemoglobin, total leukocyte counts, platelets and serum creatinine for toxicity profile while prostate specific antigen (PSA), Eastern Cooperative Oncology Group (ECOG) performance status, visual analogue scale (VAS) and analgesic quantification scale (AQS) for therapeutic efficacy were recorded pre and 8 weeks post therapy. Wilcoxon signed-rank and ANOVA tests were used for statistical analysis.RESULTS: Partial response (PR), stable disease (SD) and progressive disease (PD) for PSAwere seen in 5 (22.7%), 13 (59.1%) and 4 (18.2%) patients respectively treated with mean 6.88 GBq dose of Lu-177-PSMA. 8/22 (36.4%) patients showed ≥ 30% drop in PSA. Grade 3 haemoglobin toxicity was seen in 5/22 (22.7%) patients. No patient developed grade 4 haemoglobin toxicity. No patients had grade 3 or 4 leukocytopenia or thrombocytopenia. Wilcoxon signed-rank test showed statistical significant (P < 0.05) difference in pre and post treatment ECOG, VAS, and AQS scores. The ANOVA test showed statistically significant difference in mean doses of Lu-177-PSMA used in three PSA response groups while difference was non-significant for other variables.CONCLUSION: We concluded that Lu-177-PSMA therapy has adequate pain palliation in end-stage mCRPC patients with low performance status and it has a potential to become effective therapeutic option in properly selected patients.
