RESUMEN

A 33-year-old male presented with repeated episodes of blood-streaked sputum for last one-and half-year. Chest radiograph showed consolidation in the right lower zone. Fibreoptic bronchoscopy revealed an endoluminal growth in the right lower lobe bronchus. Histopathological examination of bronchoscopic biopsy specimen confirmed adenoid cystic carcinoma.

RESUMEN

Treatment of delayed union, malunion, and nonunion is a challenge to the orthopaedic surgeons in veterinary and human fields. Apart from restoration of alignment and stable fixation, in many cases adjunctive measures such as bone-grafting or use of bone-graft substitutes are of paramount importance. Bone-graft materials usually have one or more components: an osteoconductive matrix, which acts as scaffold to new bone growth; osteoinductive proteins, which support mitogenesis of undifferentiated cells; and osteogenic cells, which are capable of forming bone in the appropriate environment. Autologous bone remains the “gold standard” for stimulating bone repair and regeneration, but its availability may be limited and the procedure to harvest the material is associated with complications. Bone-graft substitutes can either substitute autologous bone graft or expand an existing amount of autologous bone graft. We review the currently available bone graft and graft substitutes for the novel therapeutic approaches in clinical setting of orthopaedic surgery.

RESUMEN

The present study was aimed to study the effect of an ovine follicular fluid peptide on ovarian follicle and good oocyte numbers and weights of ovary, uterus, liver, pancreas and kidney in rats, R. norvegicus. A 30.1 kDa peptide was isolated from ovine follicular fluid by ammonium sulphate precipitation and then gel filtration. The peptide was tested at various levels in normal (22 and 36 day-old), superovulated (29 day-old) immature and 121-day old mature rats on the ovarian responses and other organ weights. The isolated peptide inhibited the growth of antral follicles in normal and superovulated rats. Ovarian, uterine weight and recovery of good oocytes were reduced when the peptide was administered at 100 microg dose. The peptide had no effect on kidney, liver, pancreas weight and recovery of preantral follicles.

RESUMEN

OBJECTIVES: To evaluate the frequency and clinical importance of portal hypertensive gastropathy (PHG) and gastric varices (GV) before endoscopic sclerotherapy (EST) and after esophageal variceal obliteration. METHODS: Patients with portal hypertension (PHT) with variceal bleed were prospectively evaluated for PHG and GV before EST with intravariceal injection of absolute alcohol and after esophageal variceal obliteration. Gastric varices and PHG were characterized and graded according to previously established criteria. Patients were followed up for 12-48 (mean 37) months after variceal obliteration. RESULTS: Of 70 patients with PHT 26 had PHG before (severe in two) [18/37 in cirrhosis, 6/20 in non-cirrhotic portal fibrosis (NCPF), and 2/13 in extrahepatic portal vein obstruction (EHPVO)] and 50 had PHG after variceal obliteration (severe in 22) (27/37 in cirrhosis, p = 0.03 before versus after esophageal variceal obliteration; 16/20 in NCPF, p < 0.01; and 7/13 in EHPVO, p = ns). Type I GV (continuation of esophageal varix into the stomach) was found in 25/70 before and 5/70 after esophageal variceal obliteration (p < 0.001); in contrast, other types of GV were seen in 14/70 before and 29/70 after (p < 0.01). Overt bleeding from GV and PHG during follow-up after variceal obliteration occurred in 6 and 4 patients, respectively. CONCLUSIONS: Esophageal variceal obliteration by EST increases the frequency of PHG and GV (except type I GV which get obliterated); both PHG and GV have potential to cause rebleeding.

RESUMEN

One hundred patients with congestive cardiac failure (52 males and 48 females) with age ranging from 16 to 56 yrs (mean age 42 +/- 6) were studied to determine the relative prevalence of systolic and diastolic failures, their clinical profiles and common aetiologies. Age matched 25 control subjects were also studied to established a normal range of echocardiographic values for LV diastolic function. Thirty eight patients (38%) were found to have pure diastolic heart failure and another 5 (5%) and 57 (57%) were detected to have mixed and systolic failures respectively. An attempt to correlate the clinical assessment of diastolic failure with echo doppler study showed the sensitivity and specificity of the clinical criteria for diagnosis of diastolic heart failure to be 100% and 91.94% respectively. Of the 38 cases of diastolic failure detected 39.5% had hypertension, 31.6% ischaemic heart disease and 13.16% hypertrophic cardiomyopathy.

RESUMEN

Thirty nine patients with neuroparalytic accidents due to the use of Semple-type antirabies vaccine were studied. The mean age of the patients was 25.8 +/- 13.2 years. The suspected source of infection was the bite of a dog in 36 (92.3%) cases. The mean interval between the first dose of ARV and the onset of neurological deficits was 14.4 +/- 8.7 days. The number of doses was 7 or less in 28 (71.8%) and more than 7 in 11 (28.2%) cases. With regard to neurological deficits, 5 (12.8%) had encephalopathy, 1 (2.6%) had encephalomyeloradiculopathy, 12 (30.7%) had cervical myeloradiculopathy, 4 (10.3%) had dorsolumbar myeloradiculopathy and 17 (43.6%) had polyradiculopathy. Lumbar cerebrospinal fluid analysis was done in 31 (79.5%) cases and was abnormal in 15 (48.4%), in the form of pleocytosis or raised protein or both. Electroencephalogram was done in 24 (61.5) cases and was abnormal in 7 (29.2%); in 6 (85.7%) of theme the abnormalities were subclinical. Electroneuromyography was done in 15 (38.5%) patients and was abnormal in 13 (72.2%). Visual evoked potentials were studied in 11 (28.2%) cases and were abnormal in 2 (18.2%). Thirty six (92.3%) cases received steroids and 25 (64.1%) received cyclophosphamide in addition. The therapeutic results were better in those who received cyclophosphamide. Three patients died; One died due to respiratory failure and two due to unrelated causes while on respirator. The latter two were autopsied, and findings in the brain were unremarkable.
