Abstract: 2013 patients with various sexually transmitted diseases were screened for HIV antibodies in voluntary counseling and testing centre (VCTC) attached to Microbiology Lab of Govt. Medical College, Amritsar from Jan. 1998 to Dec. 2001. Sixty-one (3.03%) were found to be positive for HIV. 44 were males and 17 were females. There was a constant rise in the percentage positivity in females from 14.3% in 1998 to 38.09% in 2002. There was also rise in the prevalence of HIV among the STD attenders (1.65% in 1998 to 5.13% in 2001).

Abstract:
Seroprevalence of herpes simplex virus-1 and 2 antibodies in STD clinic patients
Aggarwal A,Kaur R
Indian Journal of Medical Microbiology , 2004,
Abstract: The present study was conducted on 250 serum samples of STD clinic patients and 50 serum samples of asymptomatic women to determine seroprevalence of herpes simplex-1 and 2 (HSV-1 and 2) IgM antibodies and HIV-1 and 2 antibodies. The samples were also screened for syphilis by VDRL test and confirmed by TPHA test. Seropositivity of HSV in STD clinic patients was 44/250 (17.6%) and 12/50 (24%) in asymptomatic women. In 11/44 (25%) seropositive persons for HSV, HIV 1 and 2 antibodies were present. In 10/44 (22.7%) HSV seropositive persons, coinfection with syphilis was also present, whereas in 7/44 (15.9%) HSV seropositive persons, both HIV and syphilis were present. In the control group, coinfection with other sexually transmitted infections (STIs) was not observed.

Hyaluronic acid injections for knee osteoarthritis. Systematic review of the literature.
Aggarwal A,Sempowski IP
Canadian Family Physician , 2004,
Abstract: OBJECTIVE: To determine whether viscosupplementation with intra-articular hyaluronic acid (HA) injections improves pain and function in patients with osteoarthritis (OA) in their knees. DATA SOURCES: We searched MEDLINE, Pre-MEDLINE, and Cochrane databases using the MeSH headings and key words osteoarthritis (knee) and hyaluronic acid. STUDY SELECTION: English-language case series and randomized controlled trials (RCTs) were selected. Studies with biologic, histologic, or arthroscopic outcomes were excluded. SYNTHESIS: Five case series and 13 RCTs were critically appraised. Data from three case series and three RCTs using injections of high-molecular-weight HA (Synvisc) demonstrated significant improvement in pain, activity levels, and function. The beneficial effect started as early as 12 weeks. Studies using low-molecular-weight HA had conflicting results. CONCLUSION: Viscosupplementation with high-molecular-weight HA is an effective treatment for patients with knee OA who have ongoing pain or are unable to tolerate conservative treatment or joint replacement. Viscosupplementation appears to have a slower onset of action than intra-articular steroids, but the effect seems to last longer.
Four-headed biceps brachii muscle with variant course of musculocutaneous nerve: anatomical and clinical insight
Aggarwal A,Kaur H,Sahni D,Aggarwal A
International Journal of Anatomical Variations , 2009,
Abstract: A rare case of four-headed biceps brachii muscle with variation in the course of musculocutaneous nerve was observed in left arm of a 48-year-old embalmed male cadaver. One of the extra head (third) was fleshy throughout, originated from anteromedial surface of shaft of humerus and merged with the deep surface of short head. Fourth thin tendinous head originated just below lesser tuberosity of humerus and joined with the third head. Both accessory heads were lying under cover of short head of biceps. Musculocutaneous nerve was coursing between two supernumerary heads and subsequently between third head and short head of biceps brachii muscle. Origin of third head from shaft of humerus led to passage of nerve between this head and short head, before acquiring normal position between biceps brachii and brachialis muscles, and emerging out as lateral cutaneous nerve of forearm. Intramuscular course of nerve may be a potential site for nerve compression by hypertrophied biceps associated with strenuous regular physical activity of biceps or weight lifting.
Salmonella osteomyelitis in an otherwise healthy adult male-successful management with conservative treatment: a case report.
Arora A,Singh S,Aggarwal A,Aggarwal PK
Journal of Orthopaedic Surgery , 2003,
Abstract: A 21-year-old male presented with pain in the right thigh of insidious onset and 3 months' duration. He had a history of febrile illness lasting for 15 days, 2 months prior to the onset of pain. Examination revealed swelling over the lower lateral aspect of the right thigh with some induration and tenderness. Initial X-rays of the right femur and the computed tomography scan at 10 weeks after the onset of disease were normal. Magnetic resonance imaging scan showed signal alteration with minimal destruction of the anterior cortex in the mid-diaphyseal region of the right femur. A repeated X-ray taken at 15 weeks after the onset of illness showed erosive changes, along with periosteal reaction in the diaphyseal area. The Widal test was positive. Open biopsy of the lesion revealed inflammatory non-caseating tissue. Culture of the specimen grew Salmonella typhi. The patient was given antibiotic treatment. Both X-rays and the Widal titres were normal on subsequent follow-up at 3 months.
