Fusarium flocciferum, causing wilt disease of chili (Capsicum annuum L.) in Northern Himalayas: A first report

In August 2020 chili (Capsicum annuum L.) showing wilt symptoms were collected from different districts of the Kashmir: Pulwama, Srinagar, Baramulla, and Anantnag. From each district one location was selected for sample collection and a total of 23 chili isolates were isolated. The tissue bit technique was used to isolate fungus from the infected samples on potato dextrose agar (PDA) medium, purified using the single spore technique, maintained at 25⁰±1℃ and then stored at 4° C (Ferniah et al. 2014) . Initially cultural characteristics appeared as white colonies which gradually turned to pale white colored and attained a growth of 90 mm in 18 days of incubation at 25 ± 1°C. Microscopic observations revealed that mycelium was branched and cylindrical, 3.53-4.98 µm in width. Microconidia were ellipsoidal, hyaline, 0-1 septa werepresent, and 6-7 x 3-4 µm in size. Macroconidia were cylindrical, hyaline, 2-6 septa, measuring 20-60 x 40-45 µm in size. Molecular identification of the pathogens with ITS, TEF, and RPB2 was successfully carried out and the fungi was confirmed as Fusarium flocciferum infecting chili. Amplified PCR products were sequenced and were successfully submitted and accessioned in GenBank with accession number OM189458, OM441199, OR484037 for ITS, TEF, and RPB2 gene. To confirm Koch's postulates pathogenicity test was carried out using rhizosphere inoculation technique (Najar et al. 2011, Parihar et al. 2022). In total 7 replications for sand maize meal medium (potting mixture) was prepared by autoclaving 90 g of sand and 10 g of maize meal in 250 ml of erlenmeyer flask comprising 40 ml of distilled water. The spore suspension at 100 µl per pot was inoculated and was mixed with the sterilized potting mixture in a ratio of (2:1) and up to seven days pathogen was allowed to infect the soil (Davey and Papavizas 1962; Hami et al. 2021). Then chili seeds (cv. Kashmir long-1) were sown in infected potting mixture and grown for three weeks to allow the pathogen to infect the host plants. F. flocciferum took six weeks for appearance of symptoms in the infected potted plants. Control mock inoculation of the potting mixture was carried out using water droplets instead of spore suspension at 100 µl per pot. Seven replications were kept for both inoculated and un-inoculated / control mock pots. The plants developed initial symptoms from light green to yellowish discoloration of leaves followed by the drooping, shriveling, and ultimately leading to death. The collar region of the plant was cut vertically and observed that vascular bundles showed brownish spots and discoloration, indicating wilt as the cause of death. The pathogens were re-isolated and inoculated from all infected plants, then compared with their original pure culture inoculated first, which completely resembled based on morphological, cultural, and pathogenic characteristics. No symptoms were observed on control plants. A phylogenetic analysis was also carried out using ClustalW software that grouped the species identified by different genes into different clades. F. flocciferum has been reported earlier in pea, faba bean and bamboo (Kainthola et al. 2022; Šišić et al. 2020) . In solanaceous crops, this species have been explored as wilt pathogens for the first time from India, indicating diversifying nature of Fusarium flocciferum across various hosts including solanaceous crops.

Can honey improve the quality of cryopreserved cross bred ram semen added to tris egg yolk extender?

BACKGROUND

Honey can improve the quality of cryopreserved ram semen because of its multinutrient and cryoprotective nature added to standard tris egg yolk extender.

OBJECTIVE

Different concentrations of honey were added to the standard tris egg yolk extender to improve the post-thaw quality of crossbred ram semen.

METHOD

Thirty six (36) ejaculates from eight healthy cross bred rams were pooled and divided into four aliquots. Standard tris egg yolk extender without any alteration acted as Control (C) and was supplemented with different concentrations of honey, viz. T1 (honey 1.5%), T2 (2.5%), and T3 (3.5%).

RESULTS

The percent (mean ± S.E.M) sperm motility at pre-freeze was significantly (P < 0.05) higher in Group T2 and at post-thaw in Group T3 in comparison to T1 and C treatment groups. The percent (mean ± S.E.M) HOST reacted spermatozoa at post-thaw was significantly (P < 0.05) higher in Group C and at pre-freeze the value was significantly (P < 0.05) higher in the same treatment group than Group T1. The mean MDA level (mean ± S.E.M) at post thaw was significantly (P < 0.05) lower in Group T3 than the treatment groups C and Group T1.

CONCLUSION

From this study it is concluded that the addition of 3.5% honey to the standard tris egg yolk extender provides better protection to ram semen than the addition of 1.5% honey (i.e., Control). doi.org/10.54680/fr22610110212.

Implementing 3HP vs. IPT as TB preventive treatment in Pakistan

BACKGROUND: We assessed treatment uptake and completion for 6 months of isoniazid (6H) and 3 months of isoniazid plus rifapentine weekly (3HP) in a programmatic setting in Pakistan.METHODS: All household contacts were clinically evaluated to rule out TB disease. 6H was used for TB preventive treatment (TPT) from October 2016 to April 2017; from May to September 2017, 3HP was used for contacts aged ≥2 years. We compared clinical evaluation, TPT uptake and completion rates between contacts aged ≥2 years in the 6H period and in the 3HP period.RESULTS: We identified 3,442 contacts for the 6H regimen. After clinical evaluation, 744/1,036 (72%) started treatment, while 46% completed treatment. In contrast, 3,722 contacts were identified for 3HP. After clinical evaluation, 990/1,366 (72%) started treatment, while 67% completed treatment. Uptake of TPT did not differ significantly between the 6H and 3HP groups (OR 1.03, 95%CI 0.86-1.24). However, people who initiated 3HP had 2.3 times greater odds (95% CI 1.9-2.8) of completing treatment than those who initiated 6H after adjusting for age and sex.CONCLUSION: In programmatic settings in a high-burden country, household contacts of all ages were more likely to complete TPT with shorter weekly regimens, although treatment uptake rate for the two regimens was similar.

Recent advancements in vitrification cryodevices for gamete and gonadal tissue

Cryopreservation of gametes and gonadal tissue is nowadays primarily accomplished through vitrification. Variables such as cooling rate, viscosity and volume of vitrification solution are critical in gamete vitrification. In addition, sample size and stepwise exposure are also crucial for gonadal tissue vitrification. Recently a class of cryodevices has been developed to reduce the volume of vitrification solution so as to achieve higher cooling rates. Vitrification devices are classified as "open" or "closed" depending on whether the medium comes into direct contact with liquid nitrogen during the process. Examples of the open cryodevices for gamete vitrification are Cryotop, Cryolock, open pulled straw (OPS), etc., and closed devices are Vitrisafe, CryoTip, and high security vitrification kit. Similarly, for tissue vitrification open cryodevices used are needles, cryovials and closed devices used are Cryotissue, ovarian tissue cryosystem, etc. Among all the gamete cryodevices, Cryotop is unique and the best-selling micro-volume storage device. Use of this device has resulted in the highest number of babies born after embryo or oocyte vitrification. Another novel device, Kitasato vitrification system, is a vitrification solution absorber, which is similar to Cryotop but differs in one way, as it possesses a porous membrane that absorbs extra solution from the gamete. This review provides an update on the recent use of cryodevices for gamete and gonadal tissue vitrification. doi.org/10.54680/fr22310110112.

In vitro Assessment of Tris Egg Yolk and Soybean Lecithin Based Extenders for Cryopreservation of Crossbred Ram Semen

BACKGROUND

The replacement of egg yolk with alternative plant-derived soybean lecithin is gaining interest in both animal and human sperm cryopreservation owing to biosecurity issues with egg yolk based extenders.

OBJECTIVE

To evaluate the comparative effect of egg yolk and soyabean lecithin based extenders on the quality of cryopreserved crossbred ram semen.

METHODS

Pooled ejaculates (total ejaculates = 36) were divided into two aliquots and extended with Tris egg yolk extender (Tris extender) and soybean lecithin based commercial extender (Ovixcell) RESULTS: Among the two extenders, Ovixcell showed better sperm quality both at the pre-freeze (Sperm motility) and post-thaw stages. Lower malondialdehyde (MDA) level (nmol/mL) was observed in Ovixcell as compared to Tris extender. Both sperm quality and MDA level decreased significantly (P < 0.05) from pre-freeze to post-thaw in both the extenders.

CONCLUSION

The findings of the present study indicate that Ovixcell is a comparable alternative to Tris extender for the cryopreservation of crossbred ram semen.

Helicobacter pylori Subdues Cytokine Signaling to Alter Mucosal Inflammation via Hypermethylation of Suppressor of Cytokine Signaling 1 Gene During Gastric Carcinogenesis

Helicobacter pylori infection has been associated with the onset of gastric mucosal inflammation and is known to perturb the balance between T-regulatory (Treg) and T-helper 17 (Th17) cells which causes a spurt of interleukin 17 (IL17) and transforming growth factor-β (TGF-β) from Th17 and Treg cells within the gastric milieu. IL17 instigates a surge of interleukin 6 (IL6) from T-helper 1 (Th1) and T-helper 2 (Th2) cells. Further, H. pylori infection is known to stimulate the atypical DNA methylation in gastric mucosa. However, the precise role of cytokine signaling in induction of epigenetic modifications during gastric carcinogenesis is vaguely understood. In this study, patient samples from were examined using real-time polymerase chain reaction (qPCR), PCR, methylation-specific (MS)-PCR, and enzyme-linked immunosorbent assays. We found that H. pylori infection augments the production of interleukin 10 (IL10), IL6, and TGF-β in the gastric milieu and systemic circulation. Together with the IL6/IL10 mediated hyperactivation of the JAK/STAT pathway, H. pylori infection causes the inactivation of suppressor of cytokine signaling 1 (SOCS1) gene through the hypermethylation of the promoter region. This study signifies that H. pylori-mediated epigenetic silencing of SOCS1 in concert with inflammatory cytokines miffs hyperactivation of the JAK/STAT cascade during gastric carcinogenesis.

Primary hyperparathyroidism and pancreatitis

PURPOSE

The true association between primary hyperparathyroidism (PHPT) and pancreatitis continues to be controversial. In this study, we present clinical data, investigative profile, management and follow-up of PHPT patients with pancreatitis and compare this group with PHPT patients without pancreatitis.

METHODS

Records of 242 patients with PHPT managed at our center over 24 years were retrospectively analyzed for demographic and laboratory data. The diagnosis of pancreatitis was entertained in the presence of at least two of the three following features: abdominal pain, levels of serum amylase greater than three times the normal or characteristic features at imaging.

RESULTS

Fifteen (6.19%) of the 242 consecutive patients with PHPT had had pancreatitis. Fourteen patients (93.3%) had acute pancreatitis (AP), while one patient had chronic calcific pancreatitis. Over half (8 of 14) of the patients with AP had at least two episodes of pancreatitis. Pancreatitis was the presenting symptom in 14 (93.3%) patients. None of the pancreatitis cases had additional risk factors for pancreatitis. PHPT patients with pancreatitis had significantly higher serum calcium and ALP than PHPT patients without pancreatitis. After successful parathyroidectomy, 14 patients had no further attacks of pancreatitis during a median follow-up of 16 months (range 2-41 months), while recurrence of pancreatitis was seen in one patient.

CONCLUSIONS

We conclude that pancreatitis can be the only presenting complaint of PHPT. Our study highlights the importance of fully investigating for PHPT in any pancreatitis patient with high normal or raised serum calcium level, especially in the absence of other common causes of pancreatitis.

The Impact of Elastic Deformations of the Extracellular Matrix on Cell Migration

The mechanical properties of the extracellular matrix, in particular its stiffness, are known to impact cell migration. In this paper, we develop a mathematical model of a single cell migrating on an elastic matrix, which accounts for the deformation of the matrix induced by forces exerted by the cell, and investigate how the stiffness impacts the direction and speed of migration. We model a cell in 1D as a nucleus connected to a number of adhesion sites through elastic springs. The cell migrates by randomly updating the position of its adhesion sites. We start by investigating the case where the cell springs are constant, and then go on to assuming that they depend on the matrix stiffness, on matrices of both uniform stiffness as well as those with a stiffness gradient. We find that the assumption that cell springs depend on the substrate stiffness is necessary and sufficient for an efficient durotactic response. We compare simulations to recent experimental observations of human cancer cells exhibiting durotaxis, which show good qualitative agreement.

Improving childhood tuberculosis detection and treatment through facility-based screening in rural Pakistan

SETTING

Many children with tuberculosis (TB) remain undiagnosed due to the absence of services, lack of child-friendly diagnostics and underappreciation of TB as a common cause of childhood illness.

OBJECTIVE

To show the impact of systematic verbal screening and contact tracing with appropriate management services on TB case finding in pediatric populations.

DESIGN

Between October 2014 and March 2016, children were verbally screened at the pediatric out-patient departments of four public hospitals in Jamshoro District, Pakistan. Children with symptoms or risk of TB were referred for clinical evaluation and free chest X-ray and bacteriological tests. Children with TB were started on treatment and their care givers asked to bring household members to the hospital for screening.

RESULTS

Over 105 000 children were verbally screened and 5880 presumptive childhood TB patients were identified; 1417 children (prevalence 1.3%) were diagnosed with TB; 43% were female. The median age was 5 years; 82% had pulmonary TB. An additional 390 children with TB were diagnosed through contact tracing. These activities resulted in a three-fold increase in pediatric TB case notifications.

CONCLUSION

Systematic verbal screening with clinical evaluation and free diagnostics can identify children with TB who may otherwise be missed in rural health settings.

Three port versus four port laparoscopic cholecystectomy: a prospective comparative clinical study

Background: Although, traditional laparoscopic cholecystectomy is performed using four-port technique, various modifications were made to further enhance the advantages of laparoscopic cholecystectomy. Aim of the study is to compare the results of three-port and four-port laparoscopic cholecystectomy at single center in terms of technical feasibility, safety of the procedure, operative time, intra-operative complications, postoperative pain and post-operative analgesia requirementMethods: It was a  prospective comparative study conducted  in the department of surgery Skims Medical college Srinagar, India from July 2015 to March 2017. The study was performed on all adult patients with ultrasound documented cholelithiasis and gall bladder Polyposis. The total number of patients studied was 100 which were divided into two groups of 50 each.Results: The average operative time in three port group was 29.2 minutes (range, 15-37) compared to 30.66 minutes (range, 15-42) in four port group, which was statistically insignificant. The final visual analog scores for pain in the postoperative period was 2.30 vs 2.86 in three port and four port group respectively, with a P value=0.008, which was statistically significant.Conclusions: The three-port technique is as safe as the standard four-port technique and can be a viable alternative to four port cholecystectomy with an advantage of less pain and less analgesic requirement and better cosmetic results.

Significant Pattern of Promoter Hypermethylation of UNC5C Gene in Colorectal Cancer and Its Implication in Late Stage Disease

Background:The development of Colorectal Cancer (CRC) is a complex multistep process involving an accumulation of multiple genetic and epigenetic alterations. Epigenetic modifications, particularly DNA methylation in selected gene are recognized as common molecular alterations in human tumors. Netrin-1 receptors are aberrantly methylated in primary colorectal cancer. Epigenetic alterations in the netrin-1 receptors have been found to be related with the malignant potential of CRC. Purpose: In the present study, we evaluated the role of promoter hypermethylation of UNC5C gene (one of the netrin-1 receptors) in colorectal cancer patients of Kashmiri population (North India). Hypermethylation in tumour tissue was detected by Methylation- Specific Polymerase Chain Reaction (MS-PCR). Results: UNC5C promoter hypermethylation was significantly found to be associated with colorectal cancer cases where frequency was 62% (31 of 50) and 38% (19 of 50) patients were unmethylated (p<0.0001).UNC5C methylation was significantly higher in CRCs with a frequency of 62% than 10% in corresponding normal mucosa of (p<0.0001). Further, UNC5C hypermethylation was found to be significantly associated with stage-III/IV as compared to stage I/II with a frequency of 75.8% and 42.8% respectively(p>0.05). Conclusion: We conclude that UNC5C hypermethylation is implicated in CRC which plays a role in its tumorigenesis and may predict the late stage disease.

Sterilization and Upkeep of Laparoscopic Instruments and Equipment

Sterilization is the absolute elimination or destruction of all forms of microbial life including spores. The aim of effective sterilization is to provide sterile product to the surgeon and to the patient. On the other hand disinfection is the relative removal of pathogenic organisms except spores.  JMS 2015;18(2):123-127

Unmasking childhood tuberculosis in Pakistan: efforts to improve detection and management

Childhood tuberculosis (TB) is getting increasing global attention, as tuberculous infection and TB disease in children indicate ongoing transmission in the community. In this note from the field, we highlight issues in child TB detection, management and prevention; child TB underdiagnosis, under-reporting and lack of integration with the National TB Programme are the main challenges faced in rural settings in Pakistan. We provide examples of solutions to overcome some of these challenges and enable early TB diagnosis, effective management and disease prevention in children.

Pellet gunfire injuries among agitated mobs in Kashmir

BACKGROUND

Pellet gunfire injuries inflicted while controlling agitated mobs has been studied.

METHODS

A total of 198 patients admitted to the Accident and Emergency Department with pellet gun injuries were studied in terms of anatomic site, severity and type of injury, treatment, and outcomes.

RESULTS

72.7% of patients were aged 16-25 years. The most common sites of injury were the extremities (47.9%), abdomen (36.3%) and chest (31.3%). 59.5% of patients were found to have minor injuries. Of the 80 patients admitted to the hospital for their injuries, 43 (53.7%) required an operative procedure. Six deaths (3.03%) were observed.

CONCLUSION

While the pellet wound itself may seem trivial, if not appreciated for the potential for tissue disruption and injuries to the head, chest, and abdomen, there can be catastrophic results. Patients should be evaluated and managed in the same way as those sustaining bullet injuries.:

Perioperative management of cardiac disease

Pre-existing cardiac disease contributes significantly to morbidity and mortality amongst patients undergoing non cardiac surgery. Patients with pre-existing cardiac disease or with risk factors for it, have as much as a 3.9% risk of suffering a major perioperative cardiac event (Lee et al 1999, Devereaux 2005). Furthermore, the incidence of perioperative myocardial infarction (MI) is increased 10 to 50 fold in patients with previous coronary events (Jassal 2008).

Drainage vs no drainage in secondary peritonitis with sepsis following complicated appendicitis in adults in the modern era of antibiotics

AIM

To compare the profile of postoperative outcome in secondary peritonitis with sepsis due to complicated appendicitis in two cohorts (drainage vs no-drainage) after appendicectomy in adults in the modern era of effective antibiotics.

METHODS

A retrospective review of all adult patients who were operated for secondary peritonitis with sepsis due to complicated appendicitis was carried out. Total of 209 patients were identified from May 2005 to April 2009 with operative findings of gangrenous or perforated appendix. The patients were divided into two cohorts, those where prophylactic drainage was established (n = 88) and those where no drain was used (n = 121). Abdominal drain was removed once the drainage ceased or decreased (< 10-20 mL/d in closed system of drainage or when once daily dressing was minimally soaked in open system). Broad spectrum antibiotics to cover the gut flora were started in both cohorts at diagnosis and were stopped once septic features resolved. Peritoneal fluid for aerobic culture and sensitivity were routinely obtained intra operatively; however antibiotic regimens were not changed unless patient failed to respond to the antibiotics based on the institutional protocol. The co-morbidities and their influence on primary end points were noted. Immunocompromised patients, appendicitis complicated by inflammatory bowel disorder and tumors were excluded from the study.

RESULTS

Disease stratification and other demographic features were comparable in both cohorts. There was zero mortality in drainage group while as one patient (0.82%) died in the non-drainage group. The median duration (in days) of hospital stay (6.5 vs 4); antibiotic use (5 vs 3.5); regular parental analgesic use (5 vs 3.5) and paralytic ileus (2.5 vs 2) was more common in the drainage group. Incidence of major wound infection in patients 14 (15.9%) vs 22 (18.18%) and residual intra-abdominal sepsis (inter loop collection/abscess) -7 (8%) vs 13 (10.74%) requiring secondary intervention was not significantly different in drainage and non-drainage cohorts respectively. One patient in the drainage cohort had faecal fistula (1.1%).

CONCLUSION

The complicated appendicitis in the modern era of antibiotics does not necessitate the use of prophylactic drain placement which at times may even prove counterproductive.

Atypical localizations of hydatid disease: experience from a single institute

Introduction:

The hydatid disease most often involves the liver and the lungs. The disease can involve any part of the body except the hair, teeth and nails. Primary extrahepatico-pulmonary hydatid cysts are rare and only a few sporadic cases have been reported.

Materials and Methods:

Two hundred and forty-four patients with hydatid cysts managed surgically from January 2005 to December 2009 were evaluated retrospectively. Fourteen (5.7%) patients had isolated involvement of the atypical sites, while six (2.4%) also had a primary involvement of liver.

Results:

The cysts were present in gall bladder (0.4%), peritoneum (1.6%), spleen (1.6%), ovary (0.4%), subcutaneous (0.8%), seminal vesicle (0.4%), spinal (0.4%), pancreas (0.4%), kidney (0.4%), mediastinal (0.4%), muscle (0.4%), and brain (0.8%).

Discussion and Conclusions:

Involvement of sites other than liver and lungs by hydatid disease is rare. Symptoms are related to size, location or possible complication of the cyst. It should be strongly suspected in differential diagnosis of all abdominal cysts especially in an endemic area. Proper surgical and medical management to avoid any recurrences, and a regular follow-up, are of utmost importance to detect any late complications such as local recurrence of the disease and development of hydatidosis at the primary sites.

A systematic review of air pollution as a risk factor for cardiovascular disease in South Asia: limited evidence from India and Pakistan

Cardiovascular diseases (CVD) are major contributors to mortality and morbidity in South Asia. Chronic exposure to air pollution is an important risk factor for cardiovascular diseases, although the majority of studies to date have been conducted in developed countries. Both indoor and outdoor air pollution are growing problems in developing countries in South Asia yet the impact on rising rates of CVD in these regions has largely been ignored. We aimed to assess the evidence available regarding air pollution effects on CVD and CVD risk factors in lower income countries in South Asia. A literature search was conducted in PubMed and Web of Science. Our inclusion criteria included peer-reviewed, original, empirical articles published in English between the years 1990 and 2012, conducted in the World Bank South Asia region (Afghanistan, Bangladesh, Bhutan, India, Maldives, Nepal, Pakistan and Sri Lanka). This resulted in 30 articles. Nine articles met our inclusion criteria and were assessed for this systematic review. Most of the studies were cross-sectional and examined measured particulate matter effects on CVD outcomes and indicators. We observed a bias as nearly all of the studies were from India. Hypertension and CVD deaths were positively associated with higher particulate matter levels. Biomarkers of oxidative stress such as increased levels of P-selection expressing platelets, depleted superoxide dismutase and reactive oxygen species generation as well as elevated levels of inflammatory-related C-reactive protein, interleukin-6 and interleukin-8 were also positively associated with biomass use or elevated particulate matter levels. An important outcome of this investigation was the evidence suggesting important air pollution effects regarding CVD risk in South Asia. However, too few studies have been conducted. There is as an urgent need for longer term investigations using robust measures of air pollution with different population groups that include a wider range of air pollutants and outcomes, including early indicators of CVD. These regions are facing burdens from increasing urbanization, air pollution and populations, generally weaker health infrastructure, aging populations and increased incidence of non-communicable diseases, included CVD. The extent to which the problem of air pollution and CVD will impact these countries will depend largely on the information available to inform policy and programs, which are still lacking, political will as well as social and economic development.

Ulcerative colitis: a challenge to surgeons

Ulcerative colitis is a chronic disease that specifically affects the mucosa of the rectum and colon. Although the etiology of this recurring inflammatory disorder remains essentially unknown, there have been significant advances in identifying the likely genetic and environmental factors that contribute to its pathogenesis. The clinical course of the disease typically manifests with remissions and exacerbations characterized by rectal bleeding and diarrhea. Since ulcerative colitis most commonly affects patients in their youth or early middle age, the disease can have serious long-term local and systemic consequences. There is no specific medical therapy that is curative. Although medical therapy can ameliorate the inflammatory process and control most symptomatic flares, it provides no definitive treatment for the disease. Proctocolectomy or total removal of the colon and rectum provides the only complete cure; however, innovative surgical alternatives have eliminated the need for a permanent ileostomy. The aim of this review is to provide a detailed account of the surgical management of ulcerative colitis.

Long-term results of choledochoduodenostomy in benign biliary obstruction

AIM: To determine the long-term results of choledochodudenostomy in patients with benign billiary obstruction.

METHODS: This prospective study was conducted at Sheri Kashmir Institute of Medical Sciences Srinagar Kashmir, India over a period of 10 years from January 1997 to December 2007. The total number of patients who underwent choledochoduodenostomy during this period was 270. On the basis of etiology of biliary tract obstruction, patients were divided into a calculus group, an oriental cholangiohepatitis group, a benign biliary stricture group and others. Patients were followed for a variable period of 13 mo to 15 years.

RESULTS: Choledochoduodenostomy (CDD) with duo-denotomy was performend in four patients. CDD with removal of T- tube, CDD with left hepatic lobectomy and CDD with removal of intra biliary ruptured hydatid was performed in three patients each. In the remaining patients only CDD was performed. Immediate post operative complications were seen in 63 (23%) patients, while long-term complications were seen in 28 (11%) patients, which were statistically significant. Three patients died during hospitalization while four patients died in the late post-operative period.

CONCLUSION: Our conclusion is that CDD is safe and produces good long term results when a permanent biliary drainage procedure is required.

Role of albendazole in the management of hydatid cyst liver

BACKGROUND/AIM

Hydatidosis has a worldwide distribution and the liver is the most common organ involved. Hydatid cysts of the liver can be managed either by nonoperative or operative methods. Nonoperative methods include chemotherapy and percutaneous treatment. The study aimed at understanding the effect of albendazole therapy on the viability of protoscoleces and recurrence rate of hydatid disease of the liver.

PATIENTS AND METHODS

The study was conducted at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India, over a period of 2 years from January 2002 to December 2003, with further follow-up of 5 years. The study included 72 cases in the age group of 17-66 years, comprising 39 males and 33 females. The patients were randomized into two groups of 36 patients each. In group A, patients were directly subjected to surgery, while in group B, patients were administered albendazole for 12 weeks preoperatively, followed by a further postoperative course for 12 weeks.

RESULTS

Of patients who received albendazole therapy, no patient had viable cysts at the time of surgery, as compared to 94.45% of the patients who did not receive any preoperative albendazole (P<0.01). In patients who did not receive any albendazole therapy, recurrence rate was 16.66%, while no recurrence was seen in patients who received albendazole therapy (P≤0.05).

CONCLUSION

We conclude that albendazole is an effective adjuvant therapy in the treatment of hydatid liver disease.

Breast gangrene

BACKGROUND

Breast gangrene is rare in surgical practice. Gangrene of breast can be idiopathic or secondary to some causative factor. Antibiotics and debridement are used for management. Acute inflammatory infiltrate, severe necrosis of breast tissue, necrotizing arteritis, and venous thrombosis is observed on histopathology. The aim of was to study patients who had breast gangrene.

METHODS

A prospective study of 10 patients who had breast gangrene over a period of 6 years were analyzed

RESULTS

All the patients in the study group were female. Total of 10 patients were encountered who had breast gangrene. Six patients presented with breast gangrene on the right breast whereas four had on left breast. Out of 10 patients, three had breast abscess after teeth bite followed by gangrene, one had iatrogenic trauma by needle aspiration of erythematous area of breast under septic conditions. Four had history of application of belladonna on cutaneous breast abscess and had then gangrene. All were lactating female. Amongst the rest two were elderly, one of which was a diabetic who had gangrene of breast and had no application of belladonna. All except one had debridement under cover of broad spectrum antibiotics. Three patients had grafting to cover the raw area.

CONCLUSION

Breast gangrene occurs rarely. Etiology is variable and mutifactorial. Teeth bite while lactation and the iatrogenic trauma by needle aspiration of breast abscess under unsterlised conditions could be causative. Uncontrolled diabetes can be one more causative factor for the breast gangrene. Belladonna application as a topical agent could be inciting factor. Sometimes gangrene of breast can be idiopathic. Treatment is antibiotics and debridement.

Primary splenic hydatidosis

Primary extrahepatic hydatid cysts are rare, and primary splenic hydatid cysts even more so, constituting 2% to 3.5% of all hydatid cysts. We report here a case series of isolated splenic hydatid cysts. Case records of 382 adult patients of abdominal hydatid cysts were analyzed; eight of them (2%; aged 23 to 45 years, 5 women and 3 men) had primary splenic hydatid cysts. Seven patients presented with dull dragging pain in the left hypochondrium. Four patients had splenomegaly. Diagnosis was made at ultrasonography and/or contrast-enhanced computed tomography. Enzyme linked immunosorbent assay for hydatid antibodies tested positive in all patients. One patient presented with hemoperitoneum. All patients underwent splenectomy. Primary splenic hydatid cyst is rare but should be considered in patients with cystic lesions of the spleen.

Papillary carcinoma thyroid with metastasis to ectopic cervical thymus

Papillary carcinoma of thyroid is the most common type of thyroid neoplasm which is usually confined to the thyroid and tends to metastasize to regional lymph nodes. Distant metastasis occur in up to 15% of cases. Thymic metastasis from any malignant carcinoma is extremely rare with only four cases reported in medical literature. We report a case of papillary carcinoma of thyroid metastasizing to ectopic cervical thymus which has not been previously reported.

Pyogenic liver abscess: Changing patterns in approach

AIM

To define optimum management of the pyogenic liver abscess and assess new trends in treatment.

METHODS

One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir Institute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment.

RESULTS

Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival.

CONCLUSION

Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only.

Surgical management of complicated hydatid cysts of the liver

AIM: To review the clinical presentation and surgical management of complicated hydatid cysts of the liver and to assess whether conservative surgery is adequate in the management of complicated hydatid cysts of liver.

METHODS: The study was carried out at Sher-i-Kashmir Institute of Medical Science, Srinagar, Kashmir, India. Sixty nine patients with hydatid disease of the liver were surgically managed from April 2004 to October 2005 with a follow up period of three years. It included 27 men and 42 women with a median age of 35 years. An abdominal ultrasound, computed tomography and serology established diagnosis. Patients with jaundice and high suspicion of intrabiliary rupture were subjected to preoperative endoscopic retrograde cholangiography. Cysts with infection, rupture into the biliary tract and peritoneal cavity were categorized as complicated cysts. Eighteen patients (26%) had complicated cysts and formed the basis for this study.

RESULTS: Common complications were infection (14%), intrabiliary rupture (9%) and intraperitoneal rupture (3%). All the patients with infected cysts presented with pain and fever. All the patients with intrabiliary rupture had jaundice, while only four with intrabiliary rupture had pain and only two had fever. Surgical procedures performed in complicated cysts were: infection-omentoplasty in three and external drainage in seven; intrabiliary rupture-omentoplasty in two and internal drainage in four patients. Two patients with intraperitoneal rupture underwent external drainage. There was no mortality. The postoperative morbidity was 50% in complicated cysts and 16% in uncomplicated cysts.

CONCLUSION: Complicated hydatid cyst of the liver can be successfully managed surgically with good long term results.

Evaluation of excitation functions of proton and deuteron induced reactions on enriched tellurium isotopes with special relevance to the production of iodine-124

Cross-section data for the production of medically important radionuclide (124)I via five proton and deuteron induced reactions on enriched tellurium isotopes were evaluated. The nuclear model codes, STAPRE, EMPIRE and TALYS, were used for consistency checks of the experimental data. Recommended excitation functions were derived using a well-defined statistical procedure. Therefrom integral yields were calculated. The various production routes of (124)I were compared. Presently the (124)Te(p,n)(124)I reaction is the method of choice; however, the (125)Te(p,2n)(124)I reaction also appears to have great potential.

Meckel's diverticulum-Revisited

Meckel's diverticulum is a true intestinal diverticulum that results from the failure of the vitelline duct to obliterate during the fifth week of fetal development. In about 50% cases, it contains ectopic or heterotopic tissue which can be the cause of complications. A systematic review of literature was undertaken to study the history, incidence, embryoanatomy, clinical presentation, complication and management of Meckel's diverticulum. Although Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal tract, it is often difficult to diagnose. It may remain asymptomatic or it may mimic disorders such as Crohn's disease, appendicitis and peptic ulcer disease.

Conservative management of acute appendicitis

BACKGROUND

The acute appendicitis is the most common abdominal emergency, and the primary treatment has been appendicectomy. Antibiotics are started preoperatively and continued postoperatively as needed.

METHODS

This prospective study was carried out at Sher-i-Kashmir Institute of Medical Sciences, Soura, Srinagar, Kashmir, India to determine the role of antibiotics as the only treatment in acute appendicitis and the analgesic consumption needed. Total of 80 patients were included in the study with a duration of abdominal pain less than 72 h. Out of 80 patients, 40 patients received antibiotics intravenously for 2 days followed by oral treatment for 7 days, while another 40 patients considered as controls were randomized to surgery.

RESULTS

Patients managed conservatively were discharged within 3 days except for two--patients who required surgery after 12 and 24 h, respectively, because of peritonitis due to perforated appendicitis. Four patients were readmitted within 1 year as a result of recurrent appendicitis and had to undergo surgery when appendicitis was confirmed. The diagnostic accuracy within the operated group was 90%. Two patients had perforated appendicitis at operation.

CONCLUSION

Our conclusion is that antibiotic treatment in the patients with acute appendicitis is quite effective, and these patients may not need surgery. The patients managed conservatively with antibiotics alone experience less pain and require less analgesia but have high recurrent rate.

Acute compartment syndrome--a life and limb threatening surgical emergency

Acute compartment syndrome is a life and limb threatening condition. Clinical assessment is the diagnostic cornerstone of compartment syndrome but pressure monitoring also has a role in equivocal cases, in unconscious or uncooperative patients, and in patients with nerve blocks and other forms of regional and epidural anesthesia. A high degree of suspicion and early decompression of all compartments at risk are important for a satisfactory outcome.

Delayed diagnosis of traumatic rupture of hydatid cyst of the liver--a case report

We present a patient with slow rupture of hydatid cyst into the peritoneal cavity, presenting as massive abdominal distension and respiratory embarrassment. On paracentesis, no fluid could be drained. A small lateral incision was made under local anaesthesia to drain the 'ascites', but daughter cysts typical of hydatid came out. On laparotomy, there was a cyst in the right lobe of liver which had ruptured into the peritoneal cavity leading to secondary echinococcosis.

Chromium, cobalt and titanium metallosis involving a Nottingham shoulder replacement

Metallosis after shoulder replacement has not previously been described in the literature. We report a patient who developed extensive metallosis after implantation of an uncemented Nottingham shoulder replacement. He underwent a revision procedure. Examination of the retrieved prosthesis showed that the titanium porous coating was separating from the humeral stem and becoming embedded in the ultra-high-molecular-weight polyethylene glenoid component, resulting in abrasive wear of the humeral component. There was metallosis despite exchange of the modular humeral head. Both components had to be exchanged to resolve the problem.

Acute flaccid paraplegia: a rare complication of meningococcal meningitis

STUDY DESIGN

A case report of spinal cord dysfunction following meningococcal meningitis.

OBJECTIVES

To describe a rare complication of meningococcal meningitis.

SETTING

Spinal Unit, Armed Forces Institute of Rehabilitation Medicine, Rawalpindi, Pakistan.

METHODS

A young healthy male developed meningococcal meningitis followed by acute onset low thoracic flaccid paraplegia with complete motor and sensory loss and sphincter disturbance. He responded well to antibiotics but was not investigated for causes of paraplegia. While at home in a rural area, he developed pressure ulcers, anemia and depression. Magnetic resonance imaging of the whole spine and computed tomography scan of the brain performed after 4 and 10 weeks were normal.

RESULTS

The patient had a comprehensive rehabilitation at our institute. Recovery was complicated by ossification in the right thigh, which responded well to radiotherapy. At 1-year follow-up, the motor deficit and neurogenic bladder and bowel persisted and the patient remained wheelchair dependent for mobility.

CONCLUSION

Several mechanisms have been proposed to explain spinal cord damage after meningitis. These include spinal cord infarction; autoimmune-mediated inflammatory myelopathy and direct infection of the cord. Most probable cause of spinal cord dysfunction in this case was thoracic myelopathy.

Delayed open reduction and internal fixation of a neglected fracture dislocation of the ankle

Neglected fracture dislocations of ankle are rare in western countries. Failure to achieve anatomic reduction is associated with a poor prognosis. We present a case of a patient with a neglected Weber B fracture of the fibula with postero-lateral subluxation of the ankle. In theatre, the subluxation could not be reduced, and a posterior and lateral soft tissue release was performed. Granulation tissue was removed from the medial gutter. The fibular fracture was reduced and fixed with a six-hole dynamic compression plate. Post-operative radiographs was satisfactory and the patient was followed up for 12 months with full range of movement and function of the joint. In our case, correction was not obtained by osteotomy of the lateral malleolus alone, and medial and posterior soft tissue release was required. This was due to disruption of the deltoid ligament and posterior tibiofibular ligament and the associated scar tissue. Previous studies have shown that, if anatomic reduction is achieved, results with delayed surgery can be as good as those obtained with immediate surgery. Surgically correcting an old fracture dislocation is a difficult undertaking due to soft-tissue contractures and malunited fractures. It is important to preserve as much soft tissue attachments and periosteum to prevent avascular necrosis.

Epidemiology of spinal cord injuries in the 2005 Pakistan earthquake

STUDY DESIGN

Prospective observational study.

OBJECTIVES

To identify the epidemiological features specific to spinal injuries as a result of an earthquake.

SETTINGS

Rawalpindi, Pakistan in the months after the 8 October 2005 earthquake.

METHODS

In the month after the earthquake, the one established rehabilitation center was augmented with two makeshift spinal cord centers. Information on mechanism of injury, mode of evacuation, associated injuries was gathered, and a detailed clinical and radiological assessment was performed. Neurological status and functional outcome was determined after 10 weeks.

RESULTS

Of an estimated 650-750 spinal cord injuries, 187 were admitted to these centers, including 80 men and 107 women with a mean age of 28.3+/-12.4 years. Injuries occurred while standing in 57.8% of patients. Most (83.4%) who reached the spinal cord center were airlifted. A urinary catheter had been placed before admission in 91.5%. Most of the patients were paraplegic 89.3, with 50.8% incomplete injuries. Fracture or fracture dislocation was present in 70, and 75% underwent spinal fixation. Although pressure ulcers (28.9%) and urinary tract infections (39%) were common, deep venous thromboses (4.8%) and depression (5.8%) were seldom detected. At 10 weeks, 75% were continent or performing intermittent catheterization. There were no deaths and two births.

CONCLUSION

After a disaster, evacuation of persons with a spinal cord injury to a specialized center results in low mortality. Response planning for disasters should include early aggressive medical rehabilitation.
