Background:
The indications for total knee arthroplasty (TKA) have been expanded to include younger, demanding patients. Some TKA patients expect a return to high-performance activities to restore optimum quality of life. The concept of the medial pivot (MP) TKA is that more natural knee kinematics can be achieved by altering the bearing design. In the present study, we compared the early outcomes of MP TKA with posterior-stabilized (PS) TKA in terms of patient-reported outcomes, function, and performance.
Methods:
This randomized study was performed in a high volume joint replacement facility of a tertiary care military hospital. We enrolled 40 patients each in the MP group and PS group and assessed knee flexion, patient-reported outcome (new Knee Society Score [new KSS]), patient performance (Delaware Osteoarthritis Profile Score [DOPS]), and function (Forgotten Joint Score [FJS]) at 2 years after surgery.
Results:
Compared to PS group patients, MP group patients had similar patient-reported outcomes assessed by new KSS (satisfaction, expectation, and activity scales) and FJS. MP knee patients had better performance in the timed up and go test (p < 0.026) and self-paced walk test (p < 0.002) of DOPS. The gain in knee flexion (9.3° ± 14°) compared to baseline was significantly greater in the PS group (p < 0.013).
Conclusions
When assessed by DOPS, getting up from chair and walking speed were significantly better in MP knee patients than in PS knee patients. However, considering the predictable rollback ensured by cam and post, the PS knee produced better knee flexion. Despite these results, patients were equally satisfied with the two designs.

BACKGROUNDNumerous studies have investigated the effect of angiotensin converting enzyme (ACE) gene I/D polymorphism and various cardiovascular risk factors in different populations with varied results. Currently, the association of ACE gene polymorphism with metabolic syndrome has not been studied in North Indians. While studies assessing the effect with polymorphism on each of the components of metabolic syndrome separately are present, data regarding the metabolic syndrome per se are sparse. The present study evaluated the effect of ACE gene I/D polymorphism in patients with metabolic syndrome in North Indian population at a tertiary care centre.
METHODSFifty subjects, with thirty cases of metabolic syndrome (NCEP/ATP III guidelines, 2004) and twenty age and gender matched healthy controls were chosen. Detailed history was reviewed and clinical examination of the subjects was carried out. Relevant investigations including blood glucose (fasting and post prandial), blood urea, serum creatinine and serum lipids were done. DNA of cases and controls was analysed for I/D polymorphism using polymerase chain reaction.
RESULTSD/D genotype was more frequent in patients with metabolic syndrome as compared with healthy controls (P < 0.05). Systolic blood pressure (SBP) and diastolic blood pressure (DBP) was significantly higher in the D/D genotype than I/D and I/I genotypes (P < 0.05). Our study also showed positive association between obesity, fasting blood glucose and ACE gene polymorphism while no association was found with triglycerides and high density lipoprotein cholesterol. The I/I group was significantly associated with waist circumference and fasting blood glucose (P < 0.05).
CONCLUSIONOur study clearly showed that metabolic syndrome was associated with ACE gene polymorphism. However due to less number of subjects in the study further studies are needed to corroborate our results.

We present a case of papillary thyroid cancer (post-thyroidectomy status) on regular treatment with suppressive Levothyroxine therapy. On follow-up at 6 months after radioactive iodine ablation for remnant thyroid tissue, her thyroglobulin, and anti-thyroglobulin levels were 0.06 ng/ml and 670 IU/ml, respectively. Low-dose whole-body I-131 scan was negative. To look for the cause of isolated increased anti-thyroglobulin level, a whole-body ¹⁸F-FDG PET/CT was done which revealed multiple FDG-avid lytic skeletal lesions suggestive of metastases. For confirmation of diagnosis, ¹⁸F-FDG PET/CT-guided metabolic biopsy was done, which revealed Langerhans' cell histiocytosis on histopathological examination.

Neurolymphomatosis (NL) defined as infiltration of the central nervous system or the peripheral nervous system (PNS) by malignant lymphoma cells is a rare clinical entity. However, the increasing use of fluorodeoxyglucose positron-emission tomography (FDG-PET) and magnetic resonance imaging in evaluating PNS disorders is resulting in; this condition being recognized more frequently. Here; we report five NL patients and review the current literature. We report five patients with non-Hodgkin's lymphoma (NHL) and NL, all of whom were men aged 47-69 years. The clinical presentation varied from symmetrical peripheral neuropathy to mononeuropathy. Peripheral neuropathy was the presenting manifestation of a systemic lymphoma in two patients (40%). Neuroimaging as well as whole-body FDG-PET helped in determining the correct diagnosis in all of the patients. NL is an unusual presentation of NHL resulting from infiltration of the PNS by malignant lymphomatous cells. While evaluating peripheral neuropathy, a high degree of suspicion of NL is required since the presenting symptoms vary, conventional radiology has only modest sensitivity, and a pathological diagnosis is often difficult. FDG-PET helps in the early diagnosis and treatment of this condition.
