Endoscopic staple-assisted esophagodiverticulostomy: an excellent treatment of choice for Zenker's diverticulum.

OBJECTIVES: The objectives of the present study are to review the technique of endoscopic staple-assisted esophagodiverticulostomy (ESED) for the treatment of Zenker's diverticulum and to describe our experience and modifications with ESED and the advantages of ESED over previous treatments of Zenker's diverticulum. STUDY DESIGN: Retrospective review of 74 cases of ESED performed for the treatment of Zenker's diverticulum. METHODS: Patient's records were retrospectively reviewed and tabulated for age, sex, size of diverticulum, symptoms, duration of symptoms, operative time, length of postoperative hospital stay, oral intake, complications, and relief of symptoms. RESULTS: The senior author (R.L.S) previously reported results in 36 cases of ESED performed in 34 patients with Zenker's diverticulum. We have performed an additional 38 cases of ESED in 37 patients between March 1997 and August 1999. The rate of success of ESED was similar between the two series The average perioperative time, time until oral intake, and length of postoperative hospital stay decreased in the second series. Overall, there were no mortalities and few complications with ESED. Compared with other forms of treatment of Zenker's diverticulum, such as Dohlman's procedure, diverticulectomy, and diverticulopexy, ESED has a similar rate of success, decreased perioperative time, decreased convalescence, and decreased mortality and complications. CONCLUSIONS: Cost-effectiveness, safety, and efficacy of ESED offer new advantages over previously used treatments for Zenker's diverticulum. These results continue to support the use of ESED as the initial treatment of choice for patients with Zenker's diverticulum.

Experience with the below-knee total-contact cast in the management of tibial fractures.

The method of application of the below-knee total-contact cast is illustrated, stressing the importance of firm moulding over the medial flare of the tibia, the popliteal space and the patellar tendon. Forty patients with tibial shaft fractures treated in this manner in Middlemore Hospital during the past four years are reviewed, and a comparison of some features is made with those of forty similar fractures treated in conventional above-knee plasters. The results indicate that a well-applied total contact case controls these fractures adequately and that convalescence is relatively straighforward. In addition, there are obvious advantages to the patient in respect of comfort and mobility.

Mini-laparoscopic versus laparoscopic approach to appendectomy.

BACKGROUND: The purpose of this clinical study is to evaluate the feasibility of using 2-mm laparoscopic instruments to perform an appendectomy in patients with clinically suspected acute appendicitis and compare the outcome of this mini-laparoscopic or "needlescopic" approach to the conventional laparoscopic appendectomy. METHODS: Two groups of patients undergoing appendectomy over 24 months were studied. In the first group, needlescopic appendectomy was performed in 15 patients by surgeons specializing in advanced laparoscopy. These patients were compared with the second or control group that included 21 consecutive patients who underwent laparoscopic appendectomy. We compared the patients' demographic data, operative findings, complications, postoperative pain medicine requirements, length of hospital stay, and recovery variables. Differences were considered statistically significant at a p-value < 0.05. RESULTS: Patient demographics, history of previous abdominal surgery, and operative findings were similar in both groups. There was no conversion to open appendectomy in either group. No postoperative morbidity or mortality occurred in either group. The needlescopic group had a significantly shorter mean operative time (p = 0.02), reduced postoperative narcotics requirements (p = 0.05), shorter hospital stay (p = 0.04), and quicker return to work (p = 0.03) when compared with the laparoscopic group. CONCLUSIONS: We conclude that the needlescopic technique is a safe and effective approach to appendectomy. When performed by experienced laparoscopic surgeons, the needlescopic technique results in significantly shorter postoperative convalescence and a prompt recovery.

The significance of early subtle coronary arterial lesions on echocardiogram in Kawasaki disease.

Intensive echocardiographic studies were undertaken in 37 patients with Kawasaki disease (KD) and 12 febrile controls during the acute stages. Video-tape recordings were read doubly-blinded by 3 pediatric cardiologists at 2 hospitals. Three characteristics of subtle coronary arterial lesions, including contour of lumen, smoothness of endothelium and sono-homogeneity of the surrounding tissue were particularly described. Seven of the 37 KD patients (19%) were found to have coronary arterial aneurysms (CAA) at the end of the convalescent stage. The 3 cardiologists agreed in the diagnosis of the subtle lesions by 72%. More patients with Kawasaki disease were found to have an irregular endothelium than the controls (P < 0.001). KD patients later complicated with CAA were more likely to have had the three characteristics of subtle coronary lesions during the acute stage than the KD patients without aneurysms (P < 0.001). Also, the coronary arterial size measured during the acute stage were found to be positively correlated with their largest dilatation at the convalescent stage (P = 0.0001, r = 0.61). We conclude that early subtle coronary arterial lesions can herald the development of coronary arterial aneurysms.

An outbreak of Legionella pneumophila suspected to be associated with spa pools on display at a retail store in New Zealand.

AIM: To investigate and characterise a cluster of six cases of severe pneumonia in the Wellington region notified to Regional Public Health in November 2003. And to describe the public health response to an identified subgroup of Legionella infections. METHODS: The case definition was "a person admitted to Wellington or Hutt Hospital between 29 October 2003 and 9 November 2003 with severe pneumonia". The cluster was initially investigated by interviewing patients to obtain histories of activities and exposures, and by reviewing medical notes. Medical teams sent further clinical specimens for testing (sputum for polymerase chain reaction [PCR], convalescent Legionella serology, and urine for Legionella antigen testing). Further investigation of Legionella pneumophila cases involved obtaining detailed exposure histories, environmental investigations at the suspect source of infection, and taking water and biofilm swabs for Legionella detection and serotyping. RESULTS: Three cases from the cluster were confirmed as, or compatible with, Legionella pneumophila serogroup 2. With the other three cases there was evidence of infection with L. longbeachae (two cases) or respiratory syncytial virus (one case). Exposure histories for the L. pneumophila cases revealed that the three cases had visited a Lower Hutt retail outlet with operating spa pools on display. Legionella pneumophila serogroup 1 was cultured from one of three pools. All pools were positive for Legionella on direct fluorescent antibody testing. CONCLUSIONS: Although unproven, the display spa pools were considered to be the most likely source of Legionella infection in the three cases that had visited the retail outlet. Although Legionella isolated from the pools was a different serogroup from that identified in two cases, the pools were considered to be the most likely source of infection in view of inadequate chlorination of the waters. Public health intervention to address the immediate and longer-term health risks from the pools is described. This is the second outbreak of Legionella pneumophila linked to operating display spa pools in New Zealand and it appears to be the fourth recorded outbreak of Legionnaires' disease associated with operating spa pools on display.

Immune-indian ink method for detection of hepatitis A associated antigen and antibody.

TIndian-ink grains coated with commercial gamma globulin (immune-Indian-ink) were agglutinated by 3 percent of sera from healthy volunteer blood donors; by 4 percent of those from hospital staff in contact with patients suffering from hepatitis; and by 10 percent of those from patients with viral diseases other than hepatitis, In contrast, the rate of positive reactions was 86 percent in the case of sera taken from patients in the acute phase of an illness diagnosed as hepatitis A on the basis of epidemiological and clinical data. Investigation of serum samples taken serially from patients positive in the acute phase of illness revealed that the immune-Indian-ink agglutinating factor does not persist for long in majority of cases. Two months after discharge from the hospital it was present in 18 percent of the patients only. The reaction proved negative when a limited number of cases diagnosed as hepatitis B were investigated. The immune-Indian-ink agglutinating factor was inhibited by all but one of 36 sera taken in the convalescent phase from patients with a diagnosis of hepatitis A. Some sera displaying agglutination with immune-Indian-ink gave a reaction with uncoated Indian-ink, too. Efforts to free the sera from non-specific agglutinating factor by starch-block electrophoresis have led to partial success. Fractionation on Sephadex G-200 columns suggested that in molecular weight (or particle size) the immune-Indian-ink agglutinating factor is smaller than HBsAg and larger than the non-specific agglutinating factor. On the basis of these results it is assumed that the immune-tindian-ink reaction is suitable for detecting an antigen tentatively called IH chi Ag and its antibody (IH chi Ab) specific to hepatitis A.

Comparison of laparoscopically assisted vaginal hysterectomy and abdominal hysterectomy in taiwan.

In order to clarify the feasibility of laparoscopically assisted vaginal hysterectomy (LAVH) using a not-for-extra charge instrument and to determine its cost-effectiveness in the Taiwan national health care system, we designed a prospective comparison which recruited candidates with nonmalignant uterine tumors prepared for hysterectomy to assess treatment by the laparoscopic versus the laparotomic approach. There were 144 patients in the laparoscopic group and 157 patients in the laparotomic group. The two groups were similar in characteristics. A total of 138 LAVHs were completed with six conversions (4.2%) to abdominal hysterectomy. Intraoperatively, the mean operating time in the LAVH group was longer than in the laparotomic group (134 vs 112 minutes, p < 0.001). No statistically significant differences were found between the two groups in mean estimated blood loss (260 vs 259 mL) and complications (5.8 vs 4.5%). Postoperatively, mean flatulence-relief time (27.4 vs 31.3 hours) and intramuscular meperidine requirements (1.6 vs 2.5 ampoules, 1 ampoule = 50 mg) were significantly less with LAVH. There were no differences in mean hemoglobin levels (10.7 vs 10.9 g/dL), complications (9.4 vs 13.4%, p = 0.288), or hospital stay (4.9 vs 5.2 days, p = 0.058). The mean total hospital charges (NT$48,390 vs 41,649) and insurance-paid costs (NT$43,992 vs 38,389) were significantly greater in the LAVH group. In conclusion, LAVH when performed by an experienced laparoscopist and for adequately selected patients, permits a better short-term convalescence, but is more expensive compared with conventional abdominal hysterectomy.

[Prospective study on family burden following traumatic brain injury in children].

OBJECTIVE: To collect basic information on family burdens and long-term influence of children suffered from traumatic brain injury (TBI). METHODS: Through prospective study, child behavioral problems, and injury-related family burden were assessed longitudinally in children with TBI over 6 months during the post injury period and children's pre-injury family function rated by parents soon after injury. Post injury child behavior and family outcomes were assessed at 6-month follow-up period. RESULTS: The mean adaptation partnership growth affection and resolve scale (APGAR) score of 113 children before TBI was 7.96 and score after TBI was 6.94, which had significantly difference through t test. The mean APGAR score after 6 months was 7.60, which was significantly different from the hospital data. Among group with severe TBI, the family APGAR score in hospital was significantly smaller than that before injury occurred, and the family APGAR score in 6 months after being discharged from the hospital had no significant difference with the score when staying in the hospital. The three leading dimensions among family burden scale of diseases (FBS) scores after TBI were dimension of family economic burden, family daily life and family entertainment. 6 months later, the three leading dimensions had changed to be as dimension of mental health status, dimension of family relationship and dimension of family economic burden. Mean score of child behavior checklist (CBCL) assessed at 6-months follow up period among 113 children was among normal range. CONCLUSIONS: Family function of children with TBI was affected by TBI. However, family function could be recovered along with child's convalescence except among children with severe TBI. Long-term pressure of TBI on family was revealed in mental health status and family relationship. In this study, there were no evidence of association between TBI and children's behavior problem.

Depression and physical disability outcomes in depressed medically ill hospitalized older adults.

The authors examined depression/disability outcomes in hospitalized older medical patients during the year after hospital discharge to assess the pattern and rate of changing depression and disability, the causal relationship between these variables, and to identify patients at greatest risk for poor outcomes. A group of 119 medical patients at Duke Hospital were both depressed and disabled; they were followed for a median of 47 weeks after hospital discharge. Time-series analyses showed that depression and disability tended to track together, and most changes occurred within the first 6 months after discharge. Blacks were more likely to remit from depression despite continued disability and less likely to experience continued depression despite decreased disability. Patients with a history of depression were less likely to experience improvement in depression unless disability improved. Number of medical diagnoses and depression severity independently predicted poorer depression outcomes. Certain characteristics of patients during hospitalization predict depression/disability outcomes after discharge.

Campylobacter jejuni as a cause of acute diarrhoea in children: a study at an urban hospital in Bangladesh.

The importance of C. jejuni as an aetiological agent of childhood diarrhoea was investigated at an urban children's hospital in Dhaka over a period of 1 year. C. jejuni was isolated from 25.5% of 102 diarrhoeal patients compared to 8.6% of 93 age and sex-matched healthy control children studied (P less than 0.002). The organism was isolated as a single pathogen in 17.6% of diarrhoeal patients. No C. coli was detected. The infection rate was significantly higher (P less than 0.05) amongst children up to 1 year of age (32.8%) compared to those aged over 1 year (15.9%). The clinical features of the majority of Campylobacter-positive cases resembled toxin-mediated secretory type diarrhoea. A fourfold rise of antibody titre against autologous Campylobacter strains was observed in the convalescent sera of Campylobacter-positive cases. The findings strongly suggest that C. jejuni is an important aetiological agent of childhood diarrhoea amongst Bengali children and therefore should be looked for in diarrhoeal illness.

Laparoscopic antireflux surgery and repair of hiatal hernia.

Laparoscopic mobilization of the esophagus and esophagogastric (O-G) junction enables the safe and effective performance of endoscopic antireflux surgery for intractable reflux esophagitis. The two antireflux procedures that we have evaluated in clinical practice at this institution are the ligamentum teres cardiopexy (n = 9) and partial posterior fundoplication (n = 5). More recently, laparoscopic repair of large symptomatic hiatal hernia (sliding, paraesophageal, and mixed) has also been introduced (n = 4). The procedure entails reduction of the hernia, mobilization of the O-G junction with crural repair by a continuous suture technique employing a special preformed jamming loop knot, followed by total fundoplication, which is fixed proximal to the anterior margin of the diaphragmatic hiatus and distal to the O-G junction. The early results (maximum follow-up 18 months) of this experience have been favorable, with minimal morbidity, early hospital discharge, and effective control of reflux symptoms without adverse sequelae. Laparoscopic antireflux surgery is an alternative to long-term medication in patients with intractable esophagitis, and laparoscopic repair of large hiatal hernias offers significant advantage over the conventional open surgical approach in terms of rapid convalescence.

Challenges of major incident management when excess resources are allocated: experiences from a mass casualty incident after roof collapse of a military command center.

During a military exercise in northern Norway in March 2000, the snow-laden roof of a command center collapsed with 76 persons inside. Twenty-five persons were entrapped and/or buried under snow masses. There were three deaths. Seven patients had serious injuries, three had moderate injuries, and 16 had minor injuries. A military Convalescence Camp that had been set up in a Sports Hall 125 meters from the scene was reorganized as a causality clearing station. Officers from the Convalescence Camp initially organized search and rescue. In all, 417 persons took part in the rescue work with 36 ambulances, 17 helicopters, three ambulance airplanes and one transport plane available. Two ambulances, five helicopters and one transport aircraft were used. Four patients were evacuated to a civilian hospital and six to a field hospital. The stretcher and treatment teams initially could have been more effectively organized. As resources were ample, this was a mass casualty, not a disaster. Firm incident command prevented the influx of excess resources.

Outpatient therapy of serious pediatric infections with ceftriaxone.

Convalescent outpatient parenteral antibiotic therapy with ceftriaxone was evaluated in an uncontrolled study of 101 children with documented serious bacterial infections, including meningitis. Criteria for outpatient therapy were established to assure that risks of complications from the illness were minimal at the time of discharge from the hospital. Daily physician visits and motivated, capable parents were considered essential in outpatient management. Ceftriaxone was given once daily to children with non-central nervous system infections and once or twice daily intravenously to children with meningitis. The mean durations of therapy for children with non-central nervous system infections and with meningitis were 2.4 and 4.6 days, respectively. No child enrolled in this study was readmitted to the hospital for medical or social reasons. Probable complications of treatment included diarrhea in 13% of children with meningitis and in 6% of children with non-central nervous system infections. One child with meningitis developed pseudomembranous colitis. For children who are infected with bacteria that are highly susceptible to ceftriaxone, single daily dose outpatient therapy is a reasonable option for management if a good clinical response to initial treatment is demonstrated and the risks of complications of the disease process are negligible.

[Large scale outbreak of Yersinia pseudotuberculosis serotype 5a infection at Noheji-machi in Aomori Prefecture].

In June 1991, there were large scale outbreaks of Yersinia pseudotuberculosis at 4 primary schools and 1 junior high-school in Noheji-machi in Aomori Prefecture. A total of 732 patients (725 pupils and school children, 7 teachers and personnel) were affected and 134 were hospitalized. Sex ratio of incidence was 1.1:1.0 without appreciable difference. Clinical symptoms (478 patients) were represented frequently by pyrexia (86.4%), eruption (73.8%), abdominal pain (66.7%), vomiting nausea (63.4%), etc., and were characterized by a strawberry tongue, pharyngeal redness, membranous desquamation of the fingers and arthralgia during convalescence. Yersinia pseudotuberculosis was isolated from 27 (81.8%) of 33 patients stool specimens, 1 waste water specimen and 2 (11.7%) of cooking employees' stool specimens. The isolates were confirmed serotype 5a, and positive for calcium-dependency and autoagglutination, and harboring 40-50 megadalton virulent plasmid. Restrictive endonuclease digestive pattern of plasmid proved to be identical. In many cases, patients' serum antibody titer showed a significant increase ratio to the isolated strain. In term of drug susceptibility, all the strains were sensitive to cefem, penicillin and amino-glycoside series and resistant to macrolide and sulfa series. The infectious source was limited to the school feeding, but the responsible food remained unknown. Mean latency and exposure day were presumed to be 6.5 days and May 30, respectively.

Stereotactic computed tomographic-guided aspiration and thrombolysis of intracerebral hematoma : protocol and preliminary experience.

BACKGROUND AND PURPOSE: We review preliminary experience with patients harboring intracerebral hematoma (ICH) treated by stereotactic computed tomographic (CT) guided thrombolysis and aspiration and assess procedure feasibility and safety. METHODS: Twelve patients with supratentorial ICH >/=25 mL without suspected underlying structural etiology or coagulopathy and an initial Glasgow Coma Scale (GCS) score of >/=5 were treated. A catheter was directed stereotactically or manually into the ICH through a burr hole under CT guidance. Hematoma aspiration was followed by instillation of urokinase (5 000 to 10 000 IU). This was repeated every 6 to 8 hours at bedside, with interval CT imaging, until the ICH volume diminished to <25 mL, less than half of its initial volume, or after a maximum of 10 aspirations/instillations. RESULTS: Mean age was 69 years (range 55 to 82 years). Median initial GCS was 12 (range 5 to 14). There were 7 ganglionic and 5 lobar ICH, and baseline hematoma size ranged 29 to 70 mL (mean 46 mL). Final ICH volume ranged from 14 to 51 mL (mean 21 mL), with ICH volume reduction by an average of 57% (range 38% to 70%). One patient (8. 3%) suffered hematoma expansion during the procedure. At 6 months after the procedure, 3 patients (25%) had achieved a good recovery (Glasgow Outcome Scale [GOS] score of 5), 5 patients (42%) were dependent (GOS 3), and 1 (8.3%) remained vegetative (GOS 2). Three patients (25%) died in hospital (1 from cardiac arrhythmia and 2 from respiratory failure). CONCLUSIONS: CT-guided thrombolysis and aspiration appears safe and effective in the reduction of ICH volume. Further studies are needed to assess optimal thrombolytic dosage and must include controlled comparisons of mortality, disability outcome, time until convalescence, and cost of care in treated and untreated patients.

[Tularemia: report of 16 cases in the Castilla-Leon community].

OBJECTIVE: To report the clinico-epidemiological characteristics of 16 patients with the diagnosis of tularemia. METHOD: Retrospective review of clinical records of patients admitted to the hospital or examined at health centers in Vizcaya, with clinical course and epidemiology consistent with tularemia, from January to March 1998. CASE DEFINITION: Patient with suggestive clinical course and epidemiology (exposure to hares coming from the epizootic area) and positive serology (antibodies to Francisella tularensis > 1/160 in convalescent phase serum). RESULTS: Sixteen patients (8 males, 8 females) with a mean age of 53 years. The incubation period ranged from 1 and 8 days (mean: 5). Nine patients had the ulceroganglionar form, two the pharyngeal form, one the oculoganglionar form and one the typhoidal form. In three patients only cutaneous lesion or lesions were observed. The antibiotic treatment administered included streptomycin for five patients, tobramycin for 2 patients, and ciprofloxacin, azithromycin and amoxicillin (plus doxycycline) for other three patients. Three patients received initially antitermic drugs (with poor response) and later two of them, doxycycline. The administered antibiotic in the remaining three patients was unknown. The clinical course was satisfactory in all of them and so far no relapses have been detected. CONCLUSIONS: The ulceroglandular form, as it appears in literature, was the most common form in this series of patients with tularemia. Neither severe diseases nor complications were observed. Although streptomycin is considered the drug of choice, other antibiotics are likely equally effective, at least for the non complicated forms of the disease.

[Detection of convalescent Vibrio cholerae carriers using the enterotest].

Although the existence of chronic carriers of Vibrio cholerae has been posited, the information in this regard is limited and contradictory. In order to determine the usefulness of the encapsulated string test (enterotest) for detecting V. cholerae in duodenal secretions of biliary origin (biliduodenal secretions), 59 patients (30 males and 29 females) over the age of 15 with clinically and bacteriologically diagnosed cholera were evaluated. All the patients, who were treated at the María Auxiliadora Departmental Hospital in Lima, Peru, were put on the same rehydration regimen and were given 2 g of tetracycline daily for 3 days. Between 24 h and 7 days after completion of the antibiotic treatment the first control tests were performed: culture of biliduodenal secretions obtained using enterotest and culture of feces obtained by rectal swab. No patient had diarrhea at the time of the first test. The biliduodenal secretion cultures revealed the presence of V. cholerae in five patients (8.5%) (four females and one male), while the fecal culture yielded negative results in all cases. One week later the control test was repeated on four of the five patients. All the biliduodenal secretion cultures were negative and only one fecal culture was positive at this stage. The patient in question was subjected to the same control tests one week later and both were negative. It is concluded that enterotest can be a simple, well-tolerated, low-cost method for detecting V. cholerae carriers.

Reduction of postoperative morbidity following patient-controlled morphine.

The present study examined the impact of two methods of pain management on recovery in 38 women undergoing hysterectomy. One group received IV morphine in the recovery room and IM morphine on the ward on a PRN basis (PRN group). In the other group, a loading dose of morphine 8 mg IV was given when the patient first complained of pain and patient-controlled IV morphine (PCA) was initiated and continued for 48 h (PCA group). Both groups received similar amounts of morphine overall, differently distributed over time. The PCA patients received 8 mg.h-1 in the recovery room (approximately 2.5 hrs) and less thereafter. The PRN patients received approximately 2 mg.h-1 for the entire 48-hr period. Pain control was better throughout convalescence and less variable across time with PCA management. Minute ventilation also recovered faster and by day four was 25 per cent above the preoperative baseline in the PCA group. In addition, oral temperature became normal one day earlier, ambulation recovered more rapidly and patients were discharged from hospital earlier. The data suggest that early treatment with relatively high, self-titrated morphine doses may alter the course of the metabolic response to surgery.
