One hundred and three acromegalic patients from 14 medical centers were enrolled in this study to determine the efficacy and safety of the somatostatin analog, octreotide acetate, during long term treatment. Seventy percent of the patients had undergone previous surgery or radiation treatment. Octreotide was initiated at a dose of 100 micrograms, sc, every 8 h and gradually increased to a maximum of 1500 micrograms daily depending upon the individual patient's clinical and biochemical response [GH and insulin-like growth factor I (IGF-I) reduction]. The mean duration of treatment was 24 months (range, 3-30 months). However, most patients were treated for a mean of 30 months, because this study took place after an initial 6-month study previously reported. Mean serum GH fell from 30.9 micrograms/L (range, 2.7-350) to 5.7 micrograms/L (range, 0.6-59) at the 3 months visit and remained suppressed (P < 0.001). Plasma IGF-I concentrations were also significantly reduced and remained in the normal range for at least half of the treatment visits in 56 of 87 patients (64%) treated for 12-30 months. Patients with higher initial GH concentrations were less likely to normalize IGF-I concentrations during treatment (P < 0.001). There was no evidence of drug tachyphylaxis in those patients who continued taking stable doses of medication. With some exceptions, dose increments above 800 micrograms daily in 31 patients did not provide additional benefit in terms of GH and IGF-I reduction. Headache, excessive perspiration, fatigue, and joint pain were ameliorated in 83-95% of patients. Mean finger circumference was decreased significantly at the 12 month visit (P < 0.05). The most common adverse events reported were diarrhea, abdominal discomfort, loose stools, and nausea; these symptoms usually disappeared within 3 months of treatment. Five patients discontinued octreotide because of adverse events. Of 102 patients with normal baseline ultrasound examinations of the gallbladder, 24 patients (23.5%) developed gallstones (usually during the first year of treatment), and 21 patients developed sludge alone. Gallstone formation was not related to the dose of octreotide. Most patients with cholelithiasis were asymptomatic, and none developed cholecystitis. These observations suggest that octreotide is a valuable long term medical treatment for acromegaly.

The safety of AmBisome was evaluated in 187 transplant recipients treated for 197 episodes. Patients included 89 bone marrow transplant recipients, 64 liver transplant recipients, 20 renal transplant recipients and 14 recipients of combined organs. AmBisome was instituted for verified invasive fungal infection in 34 cases, suspected invasive fungal infections in 80 cases and as prophylaxis in 83 cases. AmBisome was given for a median of 11 days (range 1-112 days) with a maximum daily dose of 1.49 +/- 0.70 mg/kg/day (mean +/- SD). The total cumulative dose of AmBisome was 1.11 +/- 1.78 g (mean +/- SD). Side-effects definitely attributed to AmBisome therapy included low potassium (n = 3), low back pain (n = 3), dyspnoea (n = 2), allergic rash (n = 1), nausea and vomiting (n = 1), confusion (n = 1), rise in alkaline phosphatase (n = 1) and cholecystitis (n = 1) with an overall incidence of 13 of 197 (7%). AmBisome was discontinued due to side-effects in 6 (3%) of the cases. During AmBisome treatment the mean cyclosporin dose was 9.6 +/- 28.8 mg/kg/day. Compared to pre- and post-AmBisome therapy there was a significantly increased cyclosporin concentration in blood during AmBisome therapy. Side-effects with possible association to AmBisome therapy included low serum potassium (36%), increase in serum creatinine (31%), rise in alkaline phosphatases (26%) and fever (3%). The overall mean increase in serum creatinine was 20%. Other possible side-effects like headache, abdominal pain, rash, rise in bilirubin, cramps and pancreatitis was seen in single patients.(ABSTRACT TRUNCATED AT 250 WORDS)

In Bucaramanga, Colombia, dengue haemorrhagic fever (DHF) has become endemo-epidemic since 1992. A cross-sectional study covering a period of 10 years (February, 1992 to February, 2002) was undertaken in children under 13 years of age hospitalized at the University Hospital. Observations were recorded on the clinical features, laboratory tests and the natural development of the disease. A total of 763 patients were examined, of whom 617 were classified as having DHF according to the WHO criteria (9.1% Grade I, 61.5% Grade II, 21.7% Grade III and 7.5% Grade IV). One hundred forty six patients could not be classified. The highest incidence took place in 1997, 1998 and 2001. Seventy four per cent of patients came from the metropolitan area of Bucaramanga; 48% were males; 0.3%, newborns; 11.8%, infants; 23%, pre-school children, and 64.9%, school children. The most important clinical features were fever and haemorrhagic manifestations (100%); vomiting (60%); abdominal pain (57%); headache (50%); osteomyalgia (40.8%); hepatomegaly (33%), and macular rash (29%). Among the haemorrhagic manifestations we found petechiae (56%); positive tourniquet test (35%); gastrointestinal bleeding (34%), and epistaxis (32%). Serous effusion was found in 17.7% of cases. Alarm signs of shock were found in 29%. Fifty two per cent had leucopenia and 37.3% atypic lymphocytes. Among other unusual manifestations were hepatitis, encephalopathy, alithiasic cholecystitis, acute renal failure, haemophagocytic syndrome and coinfections. Of the 617 cases, 12 died (1.5%).

Clinical and laboratory features, complications and treatment were retrospectively studied in 70 patients with bacteriologically documented typhoid fever, treated between January 1995 and June 2002 at Principal Hospital in Dakar, Senegal. Data analysis was done on a global basis as well as comparatively between the 37 children (under 15 years) and 33 adults. Mean age was 16.7 years (range, 1 to 52). The sex ratio was 1.4. Clinical manifestations included fever (97%), headache (50%), vomiting (71%), abdominal pain (54%), diarrhoea (49%), nnd splenomegaly (10%) without statistically significant difference between children and adults. Lyinphopenia was found in 51% of patients and anaemia in 78%. Coexisting illnesses Included malaria in 25.5% (mainly children) and hepatitis (transminases > 10N) in 24%. Complications included cholecystitis in 3 patients, gastrointestinal haemorrhage in 2, peritonitis in one, endocnrditis in one and osteomyelitis in one. Only one patient (HIV-positive) died. The incidence of antibiotic resistance was low, i.e., ainoxicilline: 2%, nalidixic acid: 1% and cotrimoxazole: 8.2%. No multidrug resistance was observed. This study shows that typhoid fever remains a major health problem in Dakar with slow resolution and potential complications. Amoxicililne and chloramphenicol can still be used for first-line treatment of typhoid fever. Little difference was found between children and adults.

An 80-year-old man who had undergone total gastrectomy and splenectomy for gastric cancer 13 years ago presented with headache, drowsiness, and high fever 1 month after a traffic accident. Brain CT scans revealed bilateral subdural fluid collections. Diffusion-weighted imaging (DWI) showed mixed high and low signal intensities in the left subdural fluid, and contrast-enhanced MR imaging revealed capsule enhancement of the left subdural fluid collection. The patient was diagnosed with left subdural empyema, and 2 burr-holes were drilled for drainage and irrigation. Operative findings revealed a neomembrane underneath the dura mater. Old hematoma and yellowish-white purulent fluid were present within the neomembrane. This confirmed the diagnosis of infected subdural hematoma (ISH). Abscess culture results were positive for Escherichia coli. The patient's symptoms resolved postoperatively with subsequent antibiotic therapy. However, 4 months after the operation, he suddenly died of severe sepsis and disseminated intravascular coagulation following cholecystitis, which was possibly associated with splenectomy. The clinical presentation, diagnosis, and treatment of an unusual case of ISH have been discussed. We emphasize that DWI and enhanced MR imaging may be useful for diagnosing ISH, and serial DWI evaluations may help in monitoring the therapeutic response in ISH.

Scrub typhus is widely distributed across the Asia-Pacific region, Taiwan included. The clinical manifestations and complications of scrub typhus vary and the illness ranges in severity from mild to fatal. The etiology of facial nerve palsy varies and infectious agents have been associated with this condition. Rickettsiae species have, however, rarely been reported as the causative agents. We report the case of a 49-year-old man who had fever, malaise, headache, oligouria and tea-colored urine. Bilateral pneumonitis, acute renal failure, acalculous cholecystitis and aseptic meningitis were diagnosed after a series of examinations. The patient recovered after doxycycline treatment but he developed bilateral facial palsy during the convalescent phase, which improved after the administration of a steroid. The diagnosis of infection with Orientia tsutsugamushi was confirmed by the Taiwan Center of Disease Control and the tests for Leptospira, Rickettsia typhi and Coxiella burnetii were all negative. This case indicates that scrub typhus needs to be included in the differential diagnoses of cases of bilateral and simultaneous facial nerve palsy, particularly in areas where the disease is endemic.

Epidemics of Dengue fever (DF) and Dengue hemorrhagic fever (DHF) are common in Southeast Asia. DF is defined & classified according to WHO criteria. Variable clinical manifestations of DF & DHF have been described in earlier studies. But some patients present with unusual clinical features and clinical profile not classifiable according to the present WHO criteria. Some of these complications if not recognized early and treated properly can even prove fatal. So this study was done to describe various clinical features in Dengue fever with special emphasis on unusual manifestations. This study was conducted at University College of Medical Sciences and associated Guru Teg Bahadur hospital; a tertiary care hospital, located in East Delhi in India. It was a retrospective study of 76 patients of probable DF; including 4 cases of DHF (according to WHO classification); 60 males & 16 females above 12 years of age admitted in medical wards of Guru Teg Bahadur hospital in an outbreak of DF which occurred during September-December 2009. The data obtained was analyzed to see clinical and laboratory profile of DF/DHF with special emphasis on unusual manifestations. The mean age of the patients was 28 +/- 9.6 years. Fever was present in all the cases with an average duration of fever being 5.47 +/- 2.2 days with body ache, (84.2%), vomiting (61.8%), abdominal pain (51.3%) and headache (19.7%) being the other presenting complaints. Hemorrhagic manifestations in the form of gum bleeding and epistaxis (35.5%), positive tourniquet test (27.6%); skin rashes (15.8%), melena (15.8%) and hematemesis (5.26%) were also present. In our study a fair no of patients presented with unusual symptoms like pain in abdomen 39 (51.3%), nausea 32 (42.1%), & vomiting 47 (61.8%), which is higher than that reported previous outbreak. Of the 39 patients who presented with abdominal pain; ultrasonography of abdomen was done in 25 patients. Fifteen (38%) of these were found to have acalculous cholecystitis. Amongst the known manifestations of DF, abdominal pain has been well described, but acalculous cholecystitis as a cause of abdominal pain is scantly reported. Another unusual manifestation was the presentation of patients (7.89%) in circulatory failure without the evidence of plasma leakage and not fulfilling all the criterion proposed by WHO for DHF/DSS. All of the above patients had very low platelet counts & tourniquet test was positive in all these six patients. Hepatomegaly and splenomegaly were observed in 34.2% and 7.89% of cases, respectively. Renal dysfunction was observed in 13.1% of cases. Laboratory investigations revealed thrombocytopenia (with a platelet count of < 100,000/microl) in all cases. Leucopenia (WBC < 4,000/mm2) and Hemoconcentration (Hct > 20% of expected for age and sex) were found in 38% and 5.26% of the cases, respectively. Results of our study indicate that apart from usual manifestations, sometimes unusual but clinically extremely important manifestations can occur which if not detected early can prove fatal. So a vigilant and timely approach is warranted.

Acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi are a rare condition. A 24-year-old female patient was admitted to our clinic with abdominal pain, nausea, fever, headache, urinary burning, and bloody urine. Based on clinical, laboratory, and radiological evaluations, the patient was diagnosed with acute acalculous cholecystitis and acute hemorrhagic cystitis due to Salmonella Typhi. The patient was treated with intravenous ceftriaxone for two weeks. After the treatment, the patient's clinical and laboratory findings improved. Acute acalculous cholecystitis due to Salmonella Typhi concomitant with acute hemorrhagic cystitis is very rare and might be difficult to diagnose. Infectious agents such as Salmonella Typhi should be considered when acute acalculous cholecystitis and acute hemorrhagic cystitis are detected in adult patients with no underlying diseases.

A 14-year-old girl was admitted to hospital with fever, headache, sore throat and abdominal pain. Her blood lymphocyte count and inflammatory markers were raised. Acute Epstein-Barr virus (EBV) infection was suspected and confirmed serologically and by measuring the viral load. On day 7, she developed jaundice with abnormal liver function tests. An abdominal ultrasound scan revealed thickening of the gallbladder and bile duct walls without calculi suggesting acute acalculous cholecystitis. The patient improved slowly with symptomatic treatment, and a repeat ultrasound scan six months later was normal. Acalculous cholecystitis is a rare complication of EBV infection and usually has a good prognosis.
