Single-stage medial plateau elevation and metaphyseal osteotomies in advanced-stage Blount’s disease: a new technique

PurposeSurgical treatment in advanced-stage infantile Blount’s disease with medial plateau (MP) depression is challenging. Several osteotomies and fixation methods have been described with no established benchmark. We conducted this study to evaluate the efficacy and safety of a new single-stage technique for acute medial condyle elevation and metaphyseal osteotomies with internal fixation.MethodsA prospective case series of 19 consecutive patients (21 knees) with severe infantile Blount’s disease underwent a single-stage MP elevation and metaphyseal osteotomies, with internal fixation. The mean age was 10.3 years (8.2 to 13.6) and the mean follow-up was 5.1 years (3.2 to 8.3). The outcome measures included clinical and radiological parameters and patient-reported pediatric outcomes data collection instrument (PODCI) score.ResultsThe mean PODCI score improved significantly from 50% to 88%. The mean internal tibial torsion improved from -27° to 11°. All cases maintained full knee extension, no limitation in flexion range of movement and no signs of instability or lateral thrust gait. All the radiographic parameters improved significantly; the mean tibiofemoral angle improved from -29° to 7°, the metaphyseal-diaphyseal angle improved from 33.4° to 4.7° and the angle of depressed MP improved from 38.3° to 2.4° (p < 0.001). At the latest follow-up, no cases of deformity recurrence were identified, the final limb-length discrepancy was < 1 cm in all patients.ConclusionSingle-stage MP elevation and metaphyseal osteotomies with internal fixation significantly improved the clinical and radiographic parameters and PODCI score in advanced infantile Blount’s disease and precluded the use of external immobilization, with no evidence of deformity recurrence.Level of evidenceIV     

Seatbelt syndrome associated with an isolated rectal injury: case report

Background

Spontaneous splenic rupture considered a relatively rare but life threatening. The three commonest causes of spontaneous splenic rupture are malignant hematological diseases, viral infections and local inflammatory and neoplastic disorders. We describe a unique and unusual case of inflammatory myofibroblastic tumor of the tail of pancreas presented with massively enlarged spleen and spontaneous splenic rupture.

Case presentation

A 19 years old male patient with no significant past medical history presented to emergency room with abdominal pain and fatigue. Massively enlarged spleen was detected. Hypotension and rapid reduction of hemoglobin level necessitated urgent laparatomy. About 1.75 liters of blood were found in abdominal cavity. A large tumor arising from the tail of pancreas and local rupture of an enlarged spleen adjacent to the tumor were detected. Distal pancreatectomy and splenectomy were performed. To our knowledge, we report the first case of massively enlarged spleen that was complicated with spontaneous splenic rupture as a result of splenic congestion due to mechanical obstruction caused by an inflammatory myofibroblastic tumor of the tail of pancreas. A review of the literature is also presented.

Conclusion

Inflammatory myofibroblastic tumor of the tail of pancreas should be included in the differential diagnosis of the etiological causes of massively enlarged spleen and spontaneous splenic rupture.     

Clinical “case series”: a concept analysis

Objectives

To analyze the concept of “case series” in the medical literature compared with case reports.

Methods

A PubMed search for articles published during 2009 which had “case series” in their title was performed. A total number of 621 articles were retrieved. 586 papers were included in the analysis and 35 were excluded (18 were commentary letters, 5 were not in English, and twelve could not be retrieved by our Library). The number of patients and category of these articles were analyzed.

Results

The median (range) of the number of cases of articles having “case series” in their title was 7 (1–6432) cases. 186/ 586 articles had less than 5 cases (31.7%, 95% CI (28.3–35.1%)). The median (range) of the number of cases of articles having “case report” as their publication type was 4 (1–178) cases. Out of the 219 articles categorized as case reports 114 (52.1%, 95% CI (45.6–58.6%)) had less than five cases.

Conclusions

The concept of “case series” is not well defined in the literature and does not reflect a specific research design. We suggest that a case series should have more than four patients while four paitents or less should be reported individually as case reports.     

Papillary thyroid carcinoma presenting as a lateral neck cyst

Background

Solitary lateral cervical cystic mass is an uncommon presentation of papillary thyroid carcinoma.

Objectives

To report our recent experience in the diagnosis and management of papillary thyroid carcinoma presenting as a lateral neck cyst.

Methods

Patients who had papillary thyroid carcinoma and presented as a painless lateral neck cyst at the Department of Surgery, Al-Ain Hospital, from April 2005 to June 2009 were retrospectively studied. Their clinical presentation, diagnosis and management were reviewed.

Results

Five patients were studied. No thyroid nodules were clinically palpable in all patients. Fine needle aspiration cytology from the cyst was positive for papillary thyroid carcinoma in three patients (60 percent). Two patients were diagnosed after excisional biopsy. Three patients had total thyroidectomy with modified radical neck dissection and postoperative radioactive iodine ablation. Two patients preferred to travel overseas for treatment. Thyroid histopathological examination has shown papillary thyroid carcinoma in all operated patients with multiple microscopic foci in two of them. This was associated with multiple bilateral cervical lymph node involvement.

Conclusions

Metastatic papillary thyroid carcinoma presenting as a neck cyst is a diagnostic challenge. Excisional biopsy is indicated if fine needle aspiration cytology was inconclusive so as to rule out malignancy.     

Factors affecting mortality of critical care trauma patients

Background

Critically-ill trauma patients have a high mortality.

Objective

To study the factors affecting the mortality of ICU trauma patients treated at Al-Ain Hospital, United Arab Emirates (UAE).

Methods

All trauma patients who were admitted to the ICU were prospectively collected over three years (2003–2006). Univariate and multivariate analysis were used to compare patients who died and who did not. Gender, age, nationality, mechanism of injury, systolic blood pressure and GCS on arrival, the need for ventilation, presence of head or chest injuries, AIS for the chest and head injuries and the ISS were studied.

Results

There were 202 patients (181 males). The most common mechanism of injury was road traffic collisions (72.3 %). The overall mortality was 13.9%. A direct logistic regression model has shown that factors that affected mortality were decreased GCS (p < 0.0001), mechanism of injury (p = 0.004) with burns having the highest mortality, increased age (p = 0.004), and increased ISS (p = 0.02). The best GCS that predicted mortality was 5.5 while the best ISS that predicted mortality was 13.5.

Conclusion

Road traffic collision is the most common cause of serious trauma in UAE followed by falls. Decreased GCS was the most significant factor that predicted mortality in the ICU trauma patients.

Bicycle-related injuries requiring hospitalization in the United Arab Emirates

ObjectivesTo study the anatomical distribution, severity, and outcome of bicycle-related injuries requiring hospitalization in Al-Ain city, United Arab Emirates in order to improve preventive measures.MethodsAll patients with bicycle-related injuries who were admitted to Al-Ain Hospital or who died after arrival were studied. Data were prospectively collected over a period of six years (October 2001–October 2007). Demography of patients, Glasgow Coma Scale (GCS), Injury Severity Score (ISS), hospital stay, and mortality were analysed.ResultsThere were 130 patients (126 males). Mean (SD) age was 27.1 (14.5) years. 17.7% were United Arab Emirates (UAE) nationals. None of the patients was wearing a helmet. The percentage of UAE nationals of less than 15 years old was significantly higher (65.2%) than non-UAE nationals (14.3%) (p < 0.0001, Fisher's Exact Test). The most common mechanism of injury for UAE nationals was falling from a bicycle (73.7%) whilst for non-UAE nationals was hitting a moving vehicle (66.7%). 96 (73.9%) patients had head and face injuries whilst 91 patients (70%) had extremity injuries. On arrival to the hospital, the median (range) ISS was 4 (1–41) and the median (range) GCS was 15 (3–15). The median (range) of total hospital stay was 4 (1–95) days. 17 patients (13.1%) were admitted to the Intensive Care Unit. Two patients died because of head injury (overall mortality was 1.5%).ConclusionsThe majority of hospitalized injured cyclists in our study were low income adults using cycling as a cheap transportation method. Compulsory helmet use by bicycle riders and subsidising helmet cost should be adopted so as to reduce morbidity and mortality of bicycle-related injuries.
