Cephalic tetanus as a result of rooster pecking: an unusual case

In this paper, a case of cephalic tetanus caused by rooster pecking to the face is presented. Cephalic tetanus is a rare type of tetanus defined by trismus and paralysis of 1 or more cranial nerves. On admission to hospital the patient had facial palsy and trismus. With proper medical management she recovered without any relapse.     

MR imaging findings of spinal dural involvement with Wegener granulomatosis

Involvement of the brain and meninges is rare in cases of Wegener granulomatosis, occurring in 2% to 8% of cases. Meningeal involvement in association with Wegener granulomatosis has scarcely been reported as being confined to the dura mater of brain on images and is thought to represent granulomatous infiltration. There are a few reported cases of Wegener granulomatosis that document involvement of dura at the level of the spinal cord. We present the case of a 52-year-old man with Wegener granulomatosis involving the cervical spinal dura and include detailed MR imaging findings.     

Renal antioxidant status in rats with hypertension induced by N sup omega nitro-L-arginine methyl ester

Nitric oxide (NO) has a role in the etiopathogenesis of hypertension. Relaxation of vascular smooth muscles is failed when NO production is reduced leading to increased vascular peripheral resistance. N sup omega nitro-L-arginine methyl ester (L-NAME) is one of the inhibitors of NO production. The aim of this study was to investigate oxidant-antioxidant systems of renal tissue in rats with hypertension induced by L-NAME. Rats were divided into three groups: control group and study groups treated with 100 or 500 mg/l L-NAME in drinking water for 15 days. The activities of catalase (CAT), glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD), and the levels of malondialdehyde (MDA) and NO were studied in the renal tissue after hypertension induction. Arterial blood pressure was increased in both L- NAME groups. CAT activity of 500-mg L-NAME group was higher than control. GSH-Px activity of 500-mg L-NAME group was decreased compared with 100-mg ones. NO level was lower in 500-mg L-NAME group than control. MDA levels in both L-NAME groups were decreased compared with control. In conclusion, hypertension was induced with oral L-NAME treatment. Increased CAT activity was compensated with decreased GSH-Px activity in 500-mg L-NAME group. Both study groups were protected from lipid peroxidation with NO inhibition.     

The effect of latanoprost, bimatoprost, and travoprost on intraocular pressure after cataract surgery.

PURPOSE: The aim of this study was to evaluate the effect of preoperative topical latanoprost, bimatoprost, and travoprost administration on postoperative intraocular pressure (IOP) after phacoemulsification and posterior chamber intraocular lens (PC IOL) implantation. METHODS: This prospective, randomized, double-masked study included 120 eyes of 120 consecutive, normotensive, uncomplicated cataract patients having phacoemulsification surgery with PC IOL implantation. They were randomized into 1 of 4 treatment groups, each of which had 30 patients. Two (2) h before the surgery, the patients received 0.005% latanoprost (Group 1), 0.004% bimatoprost (Group 2), 0.03% travoprost (Group 3), or placebo (Group 4, artificial tears). IOP was measured at preoperative, 4, 8, and 24 h postoperative with a Goldmann applanation tonometer. The anterior chamber was examined postoperatively 24 h for levels of cell and flare using slit-lamp biomicroscopy. RESULTS: The preoperative mean IOP was not statistically significant different among the four groups. In Groups 1 and 3, the mean IOP at 4, 8 and 24 h were significantly lower than the control (Group 4; P < 0.05). However, in Group 2, there was no significant difference in IOP during the study period, compared to the control (Group 4; P > 0.05). In addition, the mean postoperative IOP at 24 h in Groups 1 and 3 were significantly lower than the preoperative IOP (P < 0.05). No severe anterior chamber reaction was observed in any group. CONCLUSIONS: Our findings show that a single-dose topical of latanoprost and travoprost can prevent early postoperative IOP elevation after phacoemulsification surgery without any sideeffects.     

Prechallenge Antibodies: Moderators of Infection Rate,Signs, and Symptoms in Adults Experimentally Challenged With Rhinovirus Type 39

This study determined the influence of serum neutralizing antibody titers on infection rate, symptom manifestations, and provoked signs and pathophysiologies in adults experimentally exposed to rhinovirus type 39(RV-39). Antibody status was determined for 151 healthy volunteers who were then cloistered in a hotel for 6 days. At the end of the first cloister day, the volunteers were challenged with RV-39 in a median tissue culture infective dose of 100. On each of the 6 days, a nasal examination was performed, symptoms were scored, and objective tests of nasal mucociliary function, nasal airway patency, secretion production, and middle ear pressures were completed. Both subjects and investigators were blinded to the prechallenge serum homotypic antibody titers of the subjects. Four subjects presented with a wild virus and were excluded from the analysis. Of the 147 included subjects, prechallenge serum antibody titers to RV-39 were low (under 2) in 56 subjects, intermediate (2 to 8) in 51 subjects, and high (above 16) in 40 subjects. The high-titer group was significantly different from the low-titer group with respect to viral shedding, symptom load, subjective extent of illness, and secretion production, as well as in the frequency of subjects with abnormal nasal mucociliary clearance and positive middle ear pressures. The study results document that for experimental RV-39 exposure, high levels of homotypic serum neutralizing antibody titers are associated with protection from infection and a lessened degree of disease expression, but not with a reduction of otologic complications.

Different glomerulopathies accompanying non-small-cell lung cancer

The coexistence of lung cancer and glomerular lesion is not commonly reported. Malignancy-related glomerulopathy is commonly membranous glomerulonephritis. Other glomerulopathies are seldom reported. We report two cases presenting with non-small-cell lung cancer, acute renal failure and nephrotic syndrome secondary to membranoproliferative glomerulonephritis and amyloidosis.     

The effect of granulocyte macrophage-colony stimulating factor on bacterial translocation after administration of 5-fluorouracil in rats

BACKGROUND: After surgical resection for colorectal carcinoma there is a high recurrence rate and, therefore, adjuvant chemotherapy may be useful in some patients. 5-Fluorouracil (5-FU) is the most commonly used chemotherapeutic agent in the management of patients with colorectal cancer. However, gastrointestinal injury induced by chemotherapeutic agents may result in bacterial translocation from the gut into the systemic circulation. Granulocyte macrophage-colony stimulating factor (GM-CSF) may be used to prevent this side effect by means of macrophage activity stimulation. MATERIALS AND METHODS: A total of 45 rats were divided into three groups. Control group received intraperitoneal saline solution, 5-FU and GM-CSF groups received 50 mg/kg/day 5-FU intravenous infusion and GM-CSF group also received 200 ng/day GM-CSF subcutaneously for 6 days. Intestinal tissue was also sampled for pathological examination at day 7. Plasma levels of tumor necrosis factor-alpha and interleukin-6 were determined, bacterial translocation was quantified by lymph node, liver and spleen culture, and plasma endotoxin content was measured. RESULTS: White blood cell counts of the 5-FU rats were significantly lower than in the control and GM-CSF groups (P < 0.01). The plasma endotoxin, tumor necrosis factor-alpha and interleukin-6 levels in the 5-FU and GM-CSF groups were significantly increased at day 7 compared with the control groups (P < 0.01), but these levels were significantly lower in the GM-CSF group compared to the 5-FU group (P < 0.01). 5-FU intervention caused significant increase in the frequencies of bacterial translocation at liver, spleen, mesenteric lymph node, and portal blood. Compared with 5-FU group, GM-CSF decreased the bacterial translocation (P < 0.01). CONCLUSIONS: This study observed that the administration of 5-FU resulted in bacterial translocation. Activation of inflammatory response with GM-CSF is highly effective in prevention of bacterial translocation in 5-FU interventions.     

Elevated plasma concentrations of transforming growth factor-beta 1 in patients with unilateral ureteral obstruction

We measured plasma concentrations of TGF-beta 1 in patients with obstructive ureteral calculi and compared them with the plasma concentrations of healthy volunteers. The present study was a prospective study containing a homogenous group of patients with unilateral ureteral obstruction (UUO). The study consisted of patients with ureteral stones less than 7 mm in diameter that caused mild to moderate obstruction. All patients were referred by the emergency department of our hospital and examined between April 2003 and April 2004. The presence and characteristics of both stone and obstruction were determined by plain abdominal x-ray and gray-scale ultrasonography (US). Blood samples were collected from both patients and control individuals on admission and 1 week after conservative follow-up. The plasma TGF-beta 1 concentration was determined using a quantitative sandwich enzyme immunoassay specific for TGF-beta 1. There were 35 patients with 20 women and 15 men (average age 26.8±5.9 years), and 15 volunteers in the control group, with nine women and six men (average age 24.2±4.5 years). Average stone size was 5.6 mm±1.2 mm (range 3.5–7) for the patient group. US showed the presence of mild hydronephrosis in 24 and moderate hydronephrosis in 11 patients. Plasma concentrations of TGF-beta 1 in patients with ureteral obstruction (1,117±5.8 ng/ml, range 36–2,442 ng/ml) were significantly higher than those in the healthy control group (32±4 ng/ml) on admission (P<0.001). There was a significant increase in TGF-beta 1 plasma concentrations in the patient group (33,525±6.8 ng/ml, range 1,107–73,288 ng/ml) after 1 week follow-up (P<0.001). Ureteral obstruction increases plasma TGF-beta 1 concentrations in patients with ureteral stones as in UUO models in animal studies. A concomitant treatment with an anti-fibrotic agent may reduce the incidence of renal injury during obstruction.     

One-stage Transthoracic Operation for the Treatment of Right Lung and Liver Hydatid Cysts

In this study we reviewed our experience of hydatid disease of the lung and the liver and discussed the safety and the follow-up results of the one-stage operation. Between 1990 and 2004, 142 patients with pulmonary hydatid disease underwent operation in our clinic. Of these, 27 (19%) patients had cysts located on the dome of the liver, treated with phrenotomy through a right thoracotomy. Hydatid cysts located in the lungs were managed by means of cystotomy. For liver cysts, cystotomy and the inversion of the cavity with sutures was the surgical method of choice, and a drain was left in place. The pulmonary cysts of 12 (8.4%) patients were bilateral and 5 (3.5%) patients had prior surgical treatment of hepatic (n = 1) or pulmonary (n = 4) hydatid cysts. The liver cysts were approached transdiaphragmatically after the lung cysts were excised in 27 (19%) patients. In patients with pulmonary cysts, cystotomy, with or without capitonnage was performed on 123 (86.6%) patients, and wedge resection was performed on 11 (7.7%), segmentectomy was performed on 6 patients (4.2%), and lobectomy was performed on 2 (1.4%) patients. There was no mortality, and only a small number of complications were encountered: empyema in 3, excessive biliary drainage in 2, and bronchopleural fistula in only 1. We suggest that the extraction of pulmonary and hepatic cysts simultaneously through the transthoracic route is a useful and safe surgical technique. This technique also prevents the need for a second operation.
